Description

Active drive type folding and unfolding supporting device and mobile contact network

Technical Field

The utility model belongs to the technical field of the removal contact net, concretely relates to active drive formula receive and releases supporting device and adopt device's removal contact net.

Background

According to the existing contact net, two ends of the contact net are provided with gantries, walking devices are arranged on the gantries and are respectively connected with two ends of a movable contact line assembly, and the walking devices can drive the contact line assembly to move when walking to drive the whole contact line to move.

The length of the contact net is generally 800 meters, and the length of the contact net can reach about 1700 meters for a ten thousand ton line. If the mode has huge defects, the scheme is that a tensioned contact line drives a contact line assembly in the whole mobile contact net to move from a non-working position to a working position, the contact line assembly is arranged on a telescopic mechanism, the telescopic mechanism retracts under a natural state, and the contact line is positioned at one side edge (the non-working position) of a railway; when the running gear at both ends moves toward the work position, drives the contact line of tensioning and moves from the non-work position toward the work position (railway top), and the power that control telescopic machanism expandes comes from the contact line, adopts the problem that this kind of mode exists to have: please refer to fig. 1.

1. Bending points are formed at the connecting positions of all contact line assemblies and the contact line in the moving section of the mobile contact line system, the bending of the contact line is a problem which needs to be avoided to the utmost extent, and the bending points are necessarily formed by adopting the mode. Taking a mobile contact network of 800 meters as an example, assuming that the distance between the upright columns is 20 meters, 40 upright columns are needed, the numbers are 1, 1+ N …, 20, … and 40 respectively, a walking device is arranged on the portal frame and is connected with two ends of the mobile contact line assembly respectively, the walking device can drive the first contact line assembly to move towards the working position (the first bending point can be generated and is most obvious) when walking, and only when the telescopic mechanisms in the first and the forty upright columns are stretched to move, the telescopic mechanisms on the second and the thirty-ninth upright columns can be driven to stretch and open, and the telescopic mechanisms are driven to move towards the middle position gradually from two ends in sequence. In a tensioned contact line, only a small force is required to form the bending point, which is more apparent when used in a longer distance moving contact system.

2. The gantry crane has the condition of immovable pulling, a walking device in the gantry moves to pull a first telescopic mechanism to extend, when the first telescopic mechanism is completely stretched, a catenary cable and/or a contact line between the walking device and the first upright post telescopic mechanism is stretched to the maximum moving amount and can not be pulled any more, and the immovable pulling condition occurs. The middle telescopic mechanism does not completely move to the working position, and the traveling devices at the two ends move to the maximum moving position on the gantry and cannot be pulled again. This solution can be pulled still and not in place, especially if there is no pulling in the middle part.

3. The contact line in the whole contact net moving section can form a large arc by adopting the mode, the width of the whole arc can exceed the power-taking width range of the pantograph, and the condition that the whole moving contact net cannot be used appears.

4. This way a gravity balancing device is provided at the slider to pull the slider up, or a spring is provided below the slider to drag it, or a spring is provided above the slider to pull the slider up to overcome the inherent weight of the slider. This reduces to some extent the force required to drive the retraction mechanism to extend. However, the problem is that when the traveling devices at the two ends are in place, the contact line cannot provide any more horizontally moving tension, and particularly for the telescopic mechanism of the upright at the middle position, even if the slider is provided with upward lifting force by the counterweight, when the contact line does not provide or provide any more stretching tension, the telescopic mechanism on the upright at the middle position of the moving contact line cannot be further unfolded, and the contact line cannot be effectively pushed to the working position.

SUMMERY OF THE UTILITY MODEL

From the above, the essential reasons for the defects are that the walking device is used for driving the contact wire to move horizontally, the tensioned contact wire between the two walking devices is used for driving the telescopic mechanism to move above the net railway through the tensioned contact wire, the walking device can drive the contact wire assembly to move, so that the contact wire assembly can approach or depart from the upright column in the horizontal direction, and the telescopic mechanism stretches and supports the contact wire assembly along with the movement of the contact wire assembly.

In the scheme, a small force at any position on a tensioned contact line can form a bending point, the stretching force of any contact net component is obtained from the stretching mechanism stretching from the side position of the contact net component, when the stretching mechanisms of the first stand column and the last stand column can not be stretched, any contact net component at the middle position can not provide stretching tension from the side position, the bending point can be formed, an arc line can be formed, and the situation of the stretching mechanism which can not be stretched exists.

as shown in fig. 2A, the first: one end of the supporting structure 2 is movably connected with the moving mechanism 3, one end of the connecting piece 4 is connected with the upright post 1, and the other end of the connecting piece 4 is connected with the supporting structure 2; the connecting piece adopts flexible material to make or adopts rigid material to make in this embodiment. The driving structure provided in this embodiment is provided on the column.

As shown in fig. 2B, the third: one end of the supporting structure 2 is communicated with the upright post 1 and is movably connected with the upright post, one end of the connecting piece 4 is movably connected with the moving mechanism 3, and the other end of the connecting piece 4 is movably connected with the supporting structure 2.

As a preferred embodiment, in the present embodiment, the direction rotating mechanism 27 is used, the supporting structure 2 can rotate to move to the working position or the non-working position, and the supporting structure can realize the horizontal direction rotation of the whole supporting structure through the direction rotating mechanism 27.

In this embodiment, when the supporting structure is switched to rotate between the working position state, the non-working position state, or the working position and the non-working position, the supporting structure can rotate in the horizontal direction through the direction rotating mechanism.

The direction rotation mechanism in this embodiment includes a rotation member for providing horizontal rotation to the support structure and a rotation member for providing contraction rotation to the support structure.

As shown in fig. 2C, preferably, the first: the rotating member providing horizontal rotation of the support structure comprises a rotating shaft 28; the rotating part providing the retracting rotation for the supporting mechanism comprises a hinge part 29, the rotating shaft is arranged on the moving mechanism, the hinge part is arranged on the rotating shaft, and one end of the supporting structure is hinged with the hinge part;

in addition, as for the implementation of the direction rotating mechanism, for example, a rotating shaft is arranged on the moving mechanism, and a lantern ring is arranged at one end of the supporting structure, so that the horizontal rotation can be realized, and the lantern ring also has a swinging space in the telescopic rotating direction.

And the second method comprises the following steps: the rotating part for providing the supporting structure with horizontal rotation comprises a first rotating shaft; the rotating part for providing the retracting rotation for the supporting mechanism comprises a second rotating shaft, the first rotating shaft is arranged on the moving mechanism, and one end of the supporting structure is arranged on the second rotating shaft; or

In this embodiment, the moving mechanism is provided with a lantern ring, one end of the supporting structure is provided with another lantern ring, and the two lantern rings are buckled to realize rotation in the horizontal direction and swing in the telescopic direction.

The other implementation mode is as follows: a universal shaft is adopted, and one end of the supporting structure is arranged on the moving mechanism through the universal shaft. And so on, which are not exhaustive, that is, the support structure mounted on the moving mechanism can rotate in the telescopic rotating direction and the horizontal direction.

In this embodiment, the drive mechanism drives the movement mechanism 3 to move so that the free end of the support structure 2 drives the contact wire 5 and/or the messenger wire 6 to move to the active position or the inactive position.

The telescopic mechanism is used for moving the carrier cable and/or the contact line to a working position or a non-working position. Moving the catenary is required to place the catenary and/or contact line under tension. When the tension on the two sides of the supporting structure is unbalanced, on one hand, the unbalanced tension is easy to deform the supporting structure under the action of long time, and on the other hand, construction errors are easy to exist between the upright columns and the installation angle of the supporting structure, and particularly, the carrier cable and/or the contact line are influenced by thermal expansion and cold contraction. For example, when the whole catenary is in a working state, the existing telescopic cantilever cannot rotate in the horizontal direction, the catenary and/or the contact line of the existing telescopic cantilever are/is fixedly fixed on the cantilever (a supporting structure), the catenary and/or the contact line between the upright post and the upright post extend through a thermal expansion line body, so that the catenary between the upright post and the upright post cannot be tensioned, and the catenary and the contact line are fixedly fixed on the cantilever, so that tension provided by the tension devices on the portal frames at two ends cannot be gradually transmitted. And the utility model discloses in utilize direction rotary mechanism, bearing structure can rotate so that flexible bearing structure, and bearing structure passes through direction rotary mechanism can realize that holistic bearing structure horizontal direction rotates.

Therefore, in the process of switching the supporting structure to rotate in the working position state, the non-working position state or between the working position and the non-working position, the supporting structure can rotate in the horizontal direction through the direction rotating mechanism. Effectual solution construction error, the influence that expend with heat and contract with cold brought, the unbalanced problem of effectual solution supporting mechanism both sides pulling force in addition simultaneously can be according to the pulling automatically regulated that messenger wire andor contact wire both ends provided for messenger wire and contact wire keep at the tensioning state always, and this technical problem can not be solved to current technical mode, also can not reach the beneficial effect that the technical scheme brought.

To facilitate review, reference may be made to fig. 31 and 32, fig. 31 being a schematic view of the support structure in the extended working position; FIG. 32 is a schematic view of the support structure retracted in an inoperative position;

in this embodiment, the driving mechanism provided in each active driving type retracting and releasing support device drives the corresponding moving mechanism to move, so that the free end of the support structure drives the contact line and/or the catenary to move to the working position or the non-working position. The catenary and/or contact line directly or indirectly arranged at the free end of the supporting structure is kept at the same horizontal height and basically forms a straight line through respective driving mechanisms on the upright posts.

It should be noted that the driving mechanisms provided for the respective moving mechanisms drive the corresponding moving mechanisms to move by a corresponding amount. The utility model discloses in this kind of drive mode that sets up in permanent working process, the amount of movement of moving mechanism on the stand separately is equivalent. The problem of inconsistent movement amount of the moving mechanism in a long working process in a plurality of upright columns is solved.

In the process that a plurality of supporting structures in the mobile overhead line system are switched to rotate in the working position state, the non-working position state or between the working position and the non-working position, the supporting structures can rotate in the horizontal direction through the direction rotating mechanism. Of course, in this solution, where the connecting element is connected to the upright, a directional rotation mechanism is also used, which ensures that the connecting element can rotate both in the horizontal direction and in the horizontal direction.

Preferably, at least one of the two ends of the moving catenary is provided with a gantry, referring to fig. 30, in this embodiment, the moving catenary further includes gantries 26 arranged at the two ends of the moving catenary, and the gantry 26 is provided with a moving trolley 22 and a driving device 23, where the driving device is used for driving the moving trolley to move on a cross beam of the gantry to drive the catenary and/or the contact line to move. When the other end of the supporting structure drives the contact wire and/or the catenary to move to the working position or move to the non-working position, the moving trolley on the gantry is driven to drive the catenary and/or the contact wire to move.

In the embodiment, a suspension terminal lower anchoring device 24 is further arranged, the driving device 23 is used for driving the movable trolley 22 to move on the cross beam of the portal 26, the suspension terminal lower anchoring device 24 is arranged on the movable trolley 22, and two ends of the catenary 6 and/or the contact wire 5 are respectively anchored on the suspension terminal lower anchoring devices 24 of the portals 26 at two ends. The gantry 26 is also provided with a fixed contact suspension lower anchoring device 25, and the fixed contact line 5 is anchored on the fixed contact suspension lower anchoring device 25.

Description of the working principle: as shown in fig. 29, which is a schematic structural diagram of the catenary 6 and/or the contact wire 5 in the working position, when moving from the working position to the non-working position, the driving device 23 on the two side gantries 26 drives the moving trolley 22 to move, and the lower anchor device 24 of the suspension terminal suspended below the moving trolley 22 follows, so as to drive the catenary 6 and/or the contact wire 5 to move from the two ends to the non-working position; meanwhile, the moving mechanism 3 in each active driving type retraction supporting device moves up and down on the upright post 1, so that the other ends of all the supporting structures 2 move along the direction close to the corresponding upright post 1 to drive the whole contact line 5 and/or the carrier cable 6 to move to a non-working position;

when moving from a non-working position to a working position, the moving mechanism 3 in each active driving type retraction supporting device moves upwards on the upright post 1, so that the other ends of all the supporting structures 2 move along the direction far away from the corresponding upright post 1 to drive the whole contact line 5 and/or the messenger wire 6 to expand and move to the working position; at the same time, the driving device 23 on the gantry 26 is actuated to drive the moving trolley 22 to move. The movement of the entire contact wire 5 and/or messenger 6 to the working position is effected. In the process, because the active driving type retractable supporting device is adopted in the embodiment, the bending point condition in the prior art can be effectively avoided, and the active driving type retractable supporting device is integrally adopted in the mobile contact network, the whole carrier cable 6 and/or the contact wire 5 can be basically kept in the same straight line no matter in the process that the carrier cable 6 and/or the contact wire 5 are moved from the non-working position to the working position or in the common that the carrier cable 6 and/or the contact wire 5 are moved from the working position to the non-working position, so that the technical defect that an arc line appears in the prior art is avoided; on the other hand, each upright post 1 in the whole mobile contact network adopts an active driving type retracting and supporting device, so that the situation that the telescopic mechanism cannot be unfolded in place due to the fact that the telescopic mechanism cannot be pulled still in the prior art is avoided.

In the present embodiment, the structure for setting the two ends of the mobile contact network may further adopt that at least one of the two ends of the mobile contact network is provided with a weight, and fig. 31 shows a schematic diagram in which the weights are both provided at the two ends; the two ends of the carrier cable and/or the contact line directly or indirectly act on the balance weight 34; the balance weights arranged on the two sides are used for tensioning the carrier cable and/or the contact line; or

At least one of the two ends of the mobile catenary is provided with a spring mechanism 35, and a schematic diagram of the spring mechanism arranged at the two ends is shown in 32; the ends of the messenger and/or contact wire act directly or indirectly on the spring mechanism.

Preferably, not shown in the figures, at least one end of the moving contact net is provided with a dragging mechanism, and the pulling force provided by the dragging mechanism directly or indirectly acts on the catenary cable and/or the contact line; or

As a preferred embodiment, the two ends of the mobile overhead line system are combined in any two of the first to the fourth ways.

In the above embodiments, it is explained many times that in the related art, a tensioned catenary and/or a contact wire is adopted, and a telescopic structure is driven to expand or contract by translation of the contact wire and/or the catenary, which has a problem that a stretching force of any one contact net assembly is obtained from the telescopic mechanism which is stretched from a side position of the contact net assembly, when the telescopic mechanisms of the first and last columns cannot be stretched any more, any contact net assembly in a middle position cannot provide a stretching force from the side position any more, and a bending point is formed, so that an arc line is formed, and a situation that the contact net assembly cannot be pulled and the telescopic mechanism cannot be stretched exists.

The above scheme is that the free end of the telescopic structure is pulled to open or contract the telescopic structure by the translation of the tensioned catenary and/or contact line in the whole mobile contact network. The problem with which this is the case has already been explained above.

The other mode is that a tensioned steel wire rope is adopted at one side of a middle upright column of the whole mobile contact network to pull the sliding end of the moving mechanism in each upright column, a branch pull rope is connected at the corresponding position of each upright column and penetrates through the upper surface of the tensioned steel wire rope of the whole mobile contact network, each branch is respectively connected with the sliding end, and the sliding ends in each branch are driven to slide up or slide down by the left and right movement of the tensioned steel wire rope. This approach also has disadvantages:

1. because the movement of the sliding blocks is controlled only by one tensioned steel wire rope, in the process of stressed movement, each branch point can form a tension point when acting on the steel wire rope due to the weight of the sliding end of each branch point, the tension points cannot be kept on the same straight line, and the tensioned steel wire rope can also form an arc line and a bending point, so that the most serious result is that the sliding forming amount of the corresponding sliding end on each upright post is different, the horizontal movement of the carrier cable and/or the contact line is different under the action of the telescopic mechanism, the stroke of the horizontal movement of the carrier cable and/or the connection line is unequal, the arc line of the carrier cable and/or the contact line is formed, and the pantograph cannot effectively take electricity seriously; in addition, the inconsistent stroke of the sliding end can also cause the inconsistent horizontal height of the free end of the telescopic mechanism, so that the catenary and/or the contact line cannot be maintained at the same horizontal height, and the problem that the pantograph cannot contact the contact line when power is taken can occur.

2. In the using process of the steel wire rope, the length deformation of the steel wire rope is easily increased due to the long-term tension at the two ends, the closer the steel wire rope to the pulling motor, the larger the bearing tension of the steel wire rope, the more the deformation increment of each branch is, the influence on the pulling sliding quantity of the sliding end in each branch can be generated, the problem of the improper sliding quantity can be caused, and the radian or the bending point reflected on the carrier cable and/or the contact line can be more obvious under the action of the telescopic mechanism.

3. The problem of the expend with heat and contract with cold of wire rope itself, remove the contact net and need can work at 20 degrees below zero, 40 big temperature difference ranges on zero, according to the length 800 meters of ordinary contact net, the expend with heat and contract with cold problem of that wire rope also can lead to the stand to go up the amount of movement of moving end improper. In the longer contact network, the moving end on the upright column close to the pulling motor moves in place, and the moving end in the farther upright column does not move in place.

In practical working conditions, the three problems are commonly existed, and under the amplification of the telescopic mechanism, the contact line and/or the carrier cable can have bending points, an arc line can be formed, the stretching cannot be realized, and the condition that the telescopic mechanism cannot be unfolded or cannot be unfolded is existed.

Therefore, the utility model provides a mode such as the actuating mechanism configuration adopts the motor in each stand, push rod, lead screw, sprocket, the effectual moving amount of having guaranteed of moving mechanism is suitable. Of course, the motor adopted in the patent can also use the steel wire rope to pull the balance weight. The weight of the balance weight and the length of the steel wire rope are kept consistent under the same external parameters, such as temperature and humidity. The expend with heat and contract with cold volume of wire rope is unanimous on every stand, so the stroke volume that moving mechanism removed on the stand is equivalent, just so can effectually ensure the messenger wire and or the contact wire of support structure free end and keep at same level and form a straight line basically, the effectual pitch arc problem of having overcome appearing in the correlation technique, overcome the problem of the point of bending, overcome the problem of drawing motionless, the utility model provides a technical scheme can effectual assurance telescopic machanism expand or contract and target in place.

The mobile contact network operation principle of the embodiment is explained as follows:

the driving mechanisms arranged in each active driving type retraction supporting device drive the corresponding moving mechanisms to move, so that the moving mechanisms move upwards along the length direction of the upright posts;

the moving mechanism drives one end of the supporting structure to move upwards along the length direction of the upright post;

the free end of each supporting structure, namely the other end of each supporting structure moves along the direction far away from the upright post to drive the contact line and/or the catenary cable to move to the working position;

the contact wire and/or the carrier wire arranged directly or indirectly on the free end of each supporting structure form a basically straight line in the working position, and the contact wire and/or the carrier wire are kept at the same horizontal height.

The mobile contact network operation principle of the embodiment is explained as follows:

the driving mechanisms arranged in each active driving type retractable supporting device drive the corresponding moving mechanisms to move, so that the moving mechanisms move downwards along the length direction of the upright posts;

the moving mechanism drives one end of the supporting structure to move downwards along the length direction of the upright post;

the free end of each support structure, i.e. the other end of the support structure, moves in the direction close to the upright column to drive the contact wire and/or the catenary to move to the non-working position.

The contact wire and/or the carrier wire arranged directly or indirectly on the free end of each supporting structure form a basically straight line when in a non-working position, and the contact wire and/or the carrier wire are kept at the same horizontal height.

In this embodiment, when the other end of the support structure drives the contact wire and/or the catenary to move to the working position or to move to the non-working position, the moving trolley on the gantry drives the catenary and/or the contact wire to follow up.

In the operation method, the driving mechanism drives the moving mechanism to move, and simultaneously, the moving trolley on the portal frame is driven to drive the lower anchor device of the suspension terminal to move to the working position and be electrically connected with the fixed contact lower anchor device of the suspension terminal. At the moment, the movable contact net is in a working position state, and the freight train can drive in or drive out.

When the driving mechanism drives the moving mechanism to move, the moving trolley on the portal is driven to drive the lower anchor device of the suspension terminal to be electrically disconnected with the fixed contact lower anchor device, and the moving trolley moves to a non-working position. At this time, the mobile contact network is in a non-working position state, and the freight train can perform cargo handling operation, maintenance operation and the like.

The operation method adopts the active driving mode, so that the bending point condition in the prior art can be effectively avoided, and the technical defect of arc lines in the prior art is avoided; on the other hand, each upright post in the whole mobile contact network adopts an active driving type retracting and supporting device, so that the situation that the telescopic mechanism is not unfolded in place due to the fact that the telescopic mechanism is not pulled still in the prior art is avoided.

On the other hand, it is important to add that in the present embodiment, the travel of each moving mechanism in the movement of the corresponding column is equivalent (upward movement or downward movement). By adopting the active driving type retractable supporting device provided by the embodiment, the equivalent moving amount (stroke amount) of the moving mechanism in each upright post can be effectively ensured.

The embodiment also provides a step for balancing the tension unbalance of the left side and the right side of the supporting structure of the carrier cable and/or the contact wire pair:

during the process that the supporting structure is switched to rotate between the working position state, the non-working position state or the working position and the non-working position,

when the tension of the carrier cables and/or the contact lines on the left side and the right side acting on the supporting structure is unbalanced, the supporting structure can rotate in the horizontal direction through the direction rotating mechanism, so that the tension of the carrier cables and/or the contact lines on the left side and the right side acting on the supporting structure becomes balanced.

In the process that the supporting structure on each upright post in the mobile contact network is switched to rotate in a working position state, a non-working position state or between the working position and the non-working position, the respective supporting structure can rotate in the horizontal direction through the corresponding direction rotating mechanism. Effectual solution construction error, the influence that expend with heat and contract with cold brought, simultaneously also effectual solution support mechanism both sides unbalanced problem of pulling force, effectual tensioning contact wire andor messenger, the pulling automatically regulated that the technical scheme that provides in this implementation can also provide according to messenger and andor contact wire both ends for messenger and contact wire keep at the tensioning state always, and this technical problem can not be solved to current technical mode, also can not reach the beneficial effect that the technical scheme brought.

While embodiments of the present invention have been shown and described, it is to be understood that the above embodiments are exemplary and not to be construed as limiting the present invention, and that those skilled in the art include within their scope variations, modifications, substitutions and alterations.
