Description

In-tank car arrester, car arresting system and cage

Technical Field

The utility model relates to a car arrester installed in a cage, and also relates to the cage with the car arrester.

Background

A cage is one of the most common lifting devices for mines, for example, and people or vehicles need to be kept relatively stable after entering the cage to avoid a large amount of lateral movement of the cage. Personnel restrict its improper activity according to the safety code easily, but the vehicle easily produces fore-and-aft direction's activity in the cage lifting process, influences the stationarity that the cage promoted.

In view of this, after the trackless rubber-tyred vehicle enters the cage, it is usually necessary to manually arrange car stoppers in front of and behind the wheels to restrain the trackless rubber-tyred vehicle at a predetermined position of the cage, so as to prevent the trackless rubber-tyred vehicle from generating a large lateral movement, which affects the lifting safety of the cage. However, the manual placement of the car arrester requires a person to enter the cage first to perform the car arresting operation, which has certain safety and uncertainty. Therefore, with the development of technology, it has become a normal practice to provide a car arrester in a cage.

Chinese patent document CN109422186A discloses an automatic car arrester for elevator cage, which is provided with a first car arresting block and a second car arresting block on the same side of a cage chassis, wherein one car arresting block can limit backward movement of a vehicle entering the cage, and the other car arresting block can limit vehicle movement. The two car stopping blocks are arranged on the cage chassis in a hinged mode, and a push rod is provided to push the car stopping blocks to rotate, so that the car stopping blocks are located at car stopping positions or are turned below the track to be located at disengaging positions.

The inventors believe that it is preferable for a car arrester that a component of the respective car arrester is in a dead-centre position when, for example, a car arrester block is the prime mover. In this state, the driving portion of the car arrester should have a good driving state. In chinese patent document CN109422186A, when the car stopping block is in a car stopping state and the wheel is used as a power end, the power arm of the car stopping block is relatively large, and there is a relatively high requirement for the resistance arm of the car stopping block.

Further, chinese patent document CN211110587U discloses a car stopper in a cage, wherein a pair of stopping claws are provided at both sides of a rail in a corresponding cage and turned inward from both sides so that the stopping claws are located above a rail surface, when a car presses on the stopping claws, there are a force in a rail direction and a force perpendicular to the rail to the stopping claws, and both forces do not cause the stopping claws to be separated from the rail, thereby providing better reliability. The principle of the structural design is that the plane of the motion trail of the blocking claw is perpendicular to the running direction of the vehicle, but not parallel to the running direction of the vehicle, so that the force of the wheel acting on the blocking claw does not generate the force for enabling the blocking claw to retreat, and the vehicle blocking reliability is better. The utility model also adopts the same principle, starts from the aspect of compactness and aims to improve the use reliability. For example, in the cage internal damper disclosed in chinese patent document CN211110587U, the driving part needs to be installed on the cage, and the operating environment of the cage is relatively harsh, which affects the reliability of the driving part. Meanwhile, as the cage is lifted through the steel wire rope, the cage does not have independent power configuration, if the power (explosion-proof type) is configured for the car stopper in the cage independently, the waste is caused, an independent installation space is required, and the compactness is relatively poor.

Detailed Description

It should be noted that, for a mine, the environment at the wellhead is relatively good, the dust content and the air humidity in the mine are relatively high, and the temperature in part of the mine is relatively high, so that the environmental factors are easy to reduce the service life of related equipment.

For mines, such as cages, hoisting of the cages is usually performed by using, for example, a winch, the cages are usually of a box-type structure, an even number of roller cage shoes are usually installed on the cages, cage guides are installed on the well wall, and the cages run on the cage guides by means of the roller cage shoes, so that the relative stability of the lifting of the cages is ensured.

Leave certain distance between cage and the wall of a well, avoid cage and wall of a well collision, when for example pendulum rod 10 was set up, the pendulum rod 10 that stretches out the cage because of the support of cage to the cage of cage, and had sufficient space and make and do not produce the motion between pendulum rod 10 and the wall of a well and interfere.

In the case of a track, which has two track members, the inner side of the track is generally the space between the two track members, which is the inner side, and the opposite is the outer side, which is the reference defined by the inner and outer sides.

The same is true for cages where the space confined by the box is inside and vice versa.

The in-tank car arrester, car arresting system and cage will be described with reference to the structures illustrated in fig. 1 to 4, first, the cage is not provided with any special change in its structure, in other words, the cage is still a conventional cage, the body of the relevant in-tank car arrester is located on the lower side of the lower plate 19 of the cage, the arresting claw 7 is turned over from the outside of the in-tank rail 1, if the lower plate 19 is a cover plate which completely covers the bottom of the cage, a hole needs to be opened at the position where the arresting claw 7 protrudes, and besides, any cage in the field can be used. Here, since other structures of the cage are not related to the implementation of the present invention, the structure thereof will not be described in detail.

With regard to the cage-mounted frame of the car arrester, it is usually chosen as a beam on the underside of the lower tray 19 of the cage, or other lower part of the cage with a reliable supporting force.

The frame is a component of the mechanism, and is a stationary member relative to a movable member in the mechanism, and can be accurately read in the mechanical field.

With respect to the pawl 7, as shown in fig. 4, the crank arm 6 and the pawl 7 are both mounted on a shaft, defined for clarity as a first shaft, and the crank arm 6 and the pawl 7 are locked to a second shaft by circumferential and axial connections to the first shaft. The axial connection is mainly locked by a shaft shoulder, a shaft collar or a snap spring, and the circumferential connection is in key connection or interference connection.

Further, the axis of the first rotating shaft is parallel to the in-tank track 1, therefore, the swinging plane of the blocking claw 7 is perpendicular to the in-tank track 1, when the blocking claw 7 swings to the upper surface of the in-tank track 1, the part of the blocking claw 7, which is positioned on the upper surface of the in-tank track 1, can block the wheel 20 of the mine car, and under ideal conditions, the part of the blocking claw 7, which is positioned on the in-tank track 1, can be attached to the upper surface of the in-tank track 1, so that the in-tank track 1 can provide effective support for the blocking claw 7, and the burden of the driving part of the blocking claw 7 is reduced.

The blocking pawl 7 does not need to be rotated, but only needs to be swung (maximum rotation angle less than 360 degrees), which is understood to have two stops, one of which can be directly constrained by the upper surface of the in-tank track 1 and the other of which can be provided by the maximum stroke of the drive mechanism driving the blocking pawl 7.

The swinging is based on a repetitive work and can be understood as a form of reciprocating motion, and accordingly, with regard to the driving mechanism for driving the blocking pawl 7, which is capable of providing the required reciprocating motion, the reciprocating driving mechanism does not necessarily have to have its own motive member in the form of reciprocating motion, such as a crank-slider mechanism, and the revolving motive member can drive the slider in a reciprocating motion.

Based on the foregoing description, the movement form of the blocking claw 7 is swing, and the state that the blocking claw 7 is located on the upper surface of the in-tank track 1 is referred to as a first state, and belongs to a car-blocking state. The other state, the second state, is not blocked by the tramcar, and therefore the blocking pawl 7 should be swung away from the blocking of the wheel 20 of the tramcar.

The stopping pawl 7 illustrated in fig. 4 can avoid the limitation of the wheel 20 by swinging counterclockwise by not more than 90 degrees. Regarding the angle of rotation of the blocking pawl 7, or the rotational operating stroke, and taking secure disengagement as a design factor, the structure illustrated in fig. 4 is such that the blocking pawl 7 swings counterclockwise by an angle sufficient to effectively disengage the blocking pawl 7 from the wheel 20. In the case of a rail car, there is no interference with the movement of the wheels 20 at the designed out-of-contact corner stop point, i.e. the second condition described above.

It should be noted that, in the cage, there is an in-tank rail 1 in both of the rail-guided mine car and the trackless mine car, and the trackless mine car is parked at a position substantially on the in-tank rail 1.

Different from the existing in-tank car arrester, the driving part of the driving mechanism extends out of the lower disc body 19 of the cage to one side so as to be connected with the power part arranged at the well mouth after the cage is lifted in place.

The connection between the prime mover and the power part can be, for example, manual connection or automatic connection, the groove 16 shown in fig. 2 can realize automatic connection, because the cage lifting is limited by a guide rail, for example, the swing rod 10 equipped with a car arrester in the cage can enter the groove 16 based on up-and-down movement when the cage is lifted to a wellhead, the swing rod 10 can be pushed to move by the movement of the driving trolley 18 with the groove 16 in the direction parallel to the track 1 in the cage, and then the steel wire rope 8 is driven to pull the crank arm 12, so as to drive the blocking claw 7 to swing.

As for the pendulum rod 10 overhanging from one side to the other side of the in-tank rail 1, it is understood that the rail is a front-back direction along the rail direction, and a left-right direction perpendicular to the rail direction in the horizontal plane, which is also generally called a lateral direction, and therefore, the pendulum rod 10 overhanging from one side of the in-tank rail 1 means that the pendulum rod 10 is disposed substantially transversely to the in-tank rail 1.

In fig. 1, the upper end of the rocker 10 is hinged to the lower plate 19 via a hinge support 11, so that the rocker 10 is also pivoted.

Because the swing rod 10 is relatively long, the swing angle of the swing rod is relatively small, and the motion of the relatively long swing rod 10 at the rod end is close to linear motion. In fig. 1, the radial movement of the counter punch is achieved by using a flexible member, such as a wire 8, connected to a rocker 10.

Further, the drive mechanism includes:

rope wheels, which are installed on the lower plate 19, include ropes, such as steel wire ropes 8, steel strands, etc., and are generally used to construct pulley blocks through fixed pulleys or movable pulleys, which are satisfied in the embodiment of the present invention, and the four pulleys 9 shown in fig. 1 are all fixed pulleys.

Corresponding to the movement form of the swing link 10, wherein the rope comprises a first part parallel to the in-can track 1 and a second part perpendicular to the in-can track 1, and the first part is connected with the swing link 10; in fig. 1, the wire rope 8 forms a rectangular loop and is connected to the pendulum rod 10 using, for example, a wire rope clamp.

Further, the driving mechanism further comprises a first crank arm, such as the crank arm 12 shown in fig. 1, the crank arm 12 being connected to the second part and being mounted on the frame by a second rotating shaft, such as the rotating shaft 3 illustrated in fig. 1, for converting the linear motion of the second part into a swinging motion of the crank arm 12.

The driving mechanism further comprises an adapter which is connected with the blocking claw 7 through a connecting rod, specifically, as shown in fig. 3, the adapter is a triangular structure conversion plate 4, one vertex position of the conversion plate 4 is connected with the rotating shaft 12, the other two vertex positions are connected with one connecting rod 5 which respectively forms the connecting rod, and the connecting rod 5 is hinged with the crank arm 6.

The aforementioned connections between the connecting rod 5 and the crank arm 6, as well as the changeover panel 4, for example, are all articulated.

In some embodiments, the shaft 3 is mounted to the lower plate 19 by a pair of bearing seats 2. in fig. 1, it can be seen that the shaft 3 has a length sufficient to mount a plurality of parts on the shaft, and therefore, an adapter, such as an adapter plate 4, is mounted on the shaft section of the shaft 3 between the two bearing seats 2 for primary load bearing.

The crank arm 12 is located outside a bearing seat 2 and is correspondingly connected with the shaft head of the rotating shaft 3 for introducing power.

In fig. 3, the adapter plate 4 is of an isosceles trapezoid structure and therefore has a middle section with its own axis, substantially the axis of the rotating shaft 3, upon swinging of the adapter plate 4, the two hinge points for connection with the connecting rod 5 being symmetrical with respect to the middle section of the rotating shaft 3.

The axis of the adapter plate 4 is more precisely expressed as the axis of rotation of the adapter plate 4 itself.

As described above, the sheave system includes four sheaves 9, and the four sheaves constitute four vertexes of a rectangle to be laid on the lower side of the lower disc 19, and two sides of the rectangle are parallel to the in-tank rail 1, and the other two sides are perpendicular to the in-tank rail 1; the wire rope 8 forms a rectangular loop based on the arrangement of the four pulleys 9.

Accordingly, the two second portions each drive one crank arm 12. Each crank arm 12 drives two blocking claws 7, and the two crank arms 12 correspond to four wheels of the mine car exactly.

In relation to the car arrester in the tank, the car arrester system comprises a part located outside the tank, namely a power part, or the aforementioned power part, which is installed at the well head of the mine, and the cage can be connected to the inside part of the tank, namely, for example, the swing link 10, just after being lifted into place, to provide power. In some embodiments, the power section comprises:

a linear motion pair, the moving component of which has a motion form parallel to the in-tank track 1 and is provided with a groove 16 which is penetrated up and down, the groove 16 faces to the side of the cage and is aligned with the extending end of the moving component in the direction determined by the in-tank track 1; and
