Further, the track structure 2 is mainly used for sliding the cart 1 up and down when the cart 1 is on an incline or stairs.

Referring to fig. 1-4, two crawler belt structures 2 are laterally mounted on a supporting frame 11, in particular, the crawler belt structures 2 are rotatably or movably engaged with the supporting frame 11, and the crawler belt structures 2 extend along the length direction of the side edges of the supporting frame 11. In particular, the two track structures 2 are substantially parallel and spaced apart from each other.

The track structure 2 described above is discussed in detail in connection with fig. 1-4:

the track structure 2 comprises a track 21, the track 21 surrounding two rotating members 22 and the two rotating members 22 being driving members of the track 21, which rotating members 22 may in some examples be gears and/or pulleys, for which rotating members 22 are rotatable about respective axes of rotation, such that the track structure 2 during use has a substantially flat upper part and during use a substantially flat lower part, and the flat parts are intended to be in contact with a surface to be walked (incline and/or stairs).

In fig. 4, the trolley 1 is also provided with a drive device 23, such as an electric motor or the like, for driving the track structure 2 in operation, which drive device 23 is mainly designed for controlling the rotation of the rotating member 22, which drive device 23 may in some examples rest on the advancing surface of the trolley 1, and which drive device 23 corresponds in position to the track structure 2.

Further, the driving means 23 drive at least one transmission member 24 in rotation, which transmission member 24 is keyed to the same rotation axis as at least one rotation element 22 of the track structure 2.

In particular, in some embodiments, the number of rotating elements 22 keyed to the transmission member 24 is one, and the rotating elements 22 are the active components of the track structure 2.

In particular, in some embodiments, the rotatable member 22 is positioned laterally outboard with respect to the support frame 11 when the drive member 24 is positioned laterally inboard with respect to the support frame 11.

Further, in the cart 1, two driving devices 23 are provided, corresponding to the two track structures 2, respectively, so that each track structure 2 can be operated by the respective driving device 23 independently of the other track structure 2.

Of course, for the above-mentioned track structure 2, a tensioning wheel or roller (not shown) may also be added between the two rotating members 22 in the track 21.

Further, for the track structure 2, the outer side of the track 21 may be at least partially covered with a housing, particularly, in some embodiments, the housing is covered over or transverse to the track 21 to provide protection to the track 21.

With reference to fig. 1, the trolley 1 is provided with a structure for sliding or rolling in addition to the track structure 2, in particular, the rolling structure described above, in some embodiments, employs two wheels 12 on opposite sides of the support frame 11, the wheels 12 being used for supporting and/or moving the trolley 1.

In particular, at least two identical and coaxial wheels 12 are provided.

In particular, the wheels 12 are configured to move in a horizontal plane and/or stairs.

In particular, the aforementioned wheels 12 are mounted on the support frame 11 and positioned in correspondence with or close to the second stop 4.

In particular, the two wheels 12 are rotatable about substantially horizontal and parallel axes, and the two wheels 12 are substantially provided with a gap accommodating the second stop 4.

It should be noted that the trolley 1 according to the invention is constructed such that the axes of rotation of the two wheels 12 and the two rotational constructions provided in the track structure 2 remain substantially parallel, but not coaxial.

In connection with fig. 1, for the support frame 11, the support surface thereof is provided with a support structure on which the substation equipment to be transported is intended to be positioned and/or placed.

Further, for the support structure, the support structure comprises a first stop 3 and a second stop 4, which are angled with respect to each other, in particular, in some embodiments, the first stop 3 and the second stop 4 are arranged or defined at an angle of about 90 °.

In particular, in some embodiments the first stop 3 is arranged substantially parallel to the length direction of the track structure 2, while the second stop 4 is arranged substantially perpendicular to the length direction of the track structure 2.

With particular attention to fig. 1, the dimensions of the above-mentioned support structure can be varied to accommodate different sizes of equipment, for which purpose, in some embodiments, the second stop 4 can be designed to move relative to the first stop 3.

In general, the first stopper 3 and the second stopper 4 are designed to have a sliding structure.

Furthermore, a pushing structure, such as a pushing cylinder, may be further added to the first blocking member 3, so as to implement automatic movement of the second blocking member 4 relative to the first blocking member 3.

For the above-described support structure, the first and second stops 3, 4 define the support position of the equipment to be transported.

In particular, the above-mentioned first and second stops 3, 4 generally select a frame-like structure formed by a plurality of longitudinal members, which are separated and connected to each other by transverse bars and/or plates possibly provided with perforations, so as to constitute a continuous and complete support plane for the supporting substation equipment.

In particular, in some embodiments, the first stop 3 described above may be constituted by a blocking frame for which it has longitudinal members connected to each other by transverse plates, while the second stop 4 is defined by a plate member having a transverse extension for attachment to the blocking frame.

Further, the first blocking member 3 is mounted on a carrying frame which is mounted on the above-mentioned supporting frame 11.

In particular, the carrying frame is fixedly connected with the supporting frame 11.

In particular, the second stop 4 is mounted on the first stop 3 and/or on the carrying frame.

In connection with fig. 1, in some embodiments the hand truck 1 is equipped with a grip structure, in particular in the present embodiment the grip structure is arranged at the upper end of the hand truck 1 and is in the form of an easy-to-grip, i.e. the grip structure is mounted near a corresponding end of the hand truck 1 near the wheel 12.

In particular, with reference to fig. 1, the grip is arranged in a telescopic manner on the longitudinal member of the first stop 3.

In particular, for the grip described above, the side face thereof may also be provided with a control portion 5, such as a trigger handle 7 or a control key or the like.

In particular, the control section 5 may be mounted on a grip structure and/or a cart control device, such as a button panel, a control panel with buttons and/or levers, and/or a touch screen.

As an alternative to the control section 5 described above, the control panel for commanding and/or controlling the trolley 1 can also be positioned on a suitable remote control or other remote control system for the purpose of operating the trolley 1 without touching the trolley 1 by an operator.

It should be noted that the main functions of the grip in the above-mentioned grip structure are to facilitate the operator to move the cart 1, including the cart 1 with the body moving vertically, the cart 1 with the body moving horizontally, and the cart 1 with the body tilting or slightly tilting (see fig. 1 in particular).

In particular, in some examples, the grip structure described above may be mounted on a carrier frame that is mounted on a support frame.

In connection with fig. 1, the trolley 1 described above is also provided with means for tilting or angularly displacing the support mechanism, the support frame or the support structure relative to the track structure 2.

In particular, the means for tilting or angularly displacing the support structure may for example comprise one or more inclined pushing devices 6, such as electric jacks, hydraulic cylinders or air cylinders.

In particular, one end of the above-mentioned diagonal pushing device 6 is pivotally connected to the supporting frame 11 by means of a bearing bracket and the other end is pivotally connected to the supporting structure.

In particular, in some examples, the above-mentioned tilting means 6 may also be connected to an electronic control unit, the tilting action of the tilting means 6 being achieved by receiving a corresponding control command of the electronic control unit.

The trolley 1 in the locked state, in other words the trolley 1 in the non-carrying substation equipment, will be discussed in detail below in connection with fig. 1, where the structure of the trolley 1 in fig. 1 will be shown in detail in connection with fig. 1.

As mentioned above, the trolley 1 described above provides a support frame 11, a support structure being arranged on a support surface of the support frame 11 and being associated with the support frame 11, in this example the top surface of the support frame 11, for carrying substation equipment to be transported, a pair of wheels 12, the wheels 12 being for supporting and/or moving the trolley 1 (see fig. 1), preferably the wheels 12 being arranged on opposite sides of the support structure.

Furthermore, the trolley 1 described above provides a pair of track structures 2 arranged underneath the support frame 11, i.e. on opposite sides with respect to the support structure.

Specifically, each of the two track structures 2 comprises a track 21 or belt, the track 21 being surrounded at both ends by at least one rotating member 22, for example a sprocket wheel, for the rotating member 22.

Two of the crawler belt structures 2 are mounted on the supporting frame 11 and are arranged opposite to each other, and in particular, the crawler belt structures 2 are parallel to the length direction of the supporting frame 11.

Further, when the cart 1 is moved on the inclined surface or step in the middle, the illustrated horizontal plane, the crawler belt structure 2 is used, since the crawler belt 21 clamps the edge of the stair step or the crawler belt 21 contacts on the inclined plane, the cart 1 can tilt and translate the general transportation substation equipment along the quasi-line of the stair itself or the inclined plane, and the operator can easily move the cart 1 through the grip structure.

Further, as mentioned above, each track structure 2 comprises at least two rotating elements 22, the two rotating elements 22 being respectively a driving rotating element 22 and a driven rotating element 22, the driving rotating elements 22 being integrated in a transmission member 24 driven by suitable driving means 23 and being keyed by means of the same rotation axis, the driving rotating elements 22 thus defining the position of the transmission member 24.

Specifically, the driving rotating member 22 is a rotating member 22 that actively drives the crawler belt structure 2 to operate, and the driven rotating member 22 is a rotating member 22 that is idle and passively rotates.

Further, since the active rotary member 22 is keyed to a rotational shaft to which the transmission member 24 is keyed, the transmission member 24 is connected to an output portion of the driving device 23 via a belt, in particular, a transmission joint of the driving device 23, for example, a pulley structure connected to an output shaft of the driving device 23.

Each track structure 2 of the trolley 1 described above comprises an active rotation element 22 rotating integrally with a transmission member 24, the transmission member 24 being connected to a drive 23 of the trolley 1, either directly or through a further transmission structure.

Preferably, the transmission member 24 may be connected with a belt to a transmission joint connected to the driving device 23 for further connection of the driving device 23.

Preferably, in the embodiment of the trolley 1 shown in fig. 3, the transmission member 24 is arranged in the vicinity of the wheels 12, although in alternative embodiments it may be provided that the transmission member 24 is positioned at the driven rotator 22, with equivalent technical effects.

Preferably, the rotating member 22 comprises an element having an at least partially annular configuration.

Preferably, the rotating member 22 has an outer toothed profile around which the crawler belt 21 of the crawler belt structure 2 is wound, and the inner profile of the rotating member 22 is connected to the rotating shaft by a key and rotates with respect to the braking portion 8, and the braking portion 8 is mounted on the supporting frame 11 and constitutes an integral structure with the supporting frame 11.

Preferably, the rotating member 22 includes a gear, although the rotating member 22 may alternatively include a sprocket.

Furthermore, on the side of the support frame 11, a support seat for defining the drive means 23 may be fitted.

Preferably, the support base is removable.

The trolley 1 in this example also comprises a control part 5, which control part 5 is controllable by an operator and which correspondingly controls at least one rotating member 22 in the track structure 2, which rotating member 22 is preferably an active rotating member 22.

The braking means constituted by the spring 84 structure is disposed inside the rotating member 22 for the purpose of braking/stopping the rotation of the rotating member 22 and thus the movement state of the track structure 2.

Normally, the brake device is in its contracted state under the action of an externally applied force to maintain the brake device at a distance from the rotating member 22, thereby allowing the rotating member 22 to rotate and thus allowing the forward rotational movement of the track structure 2.

Preferably, the braking device may be mounted on either the driving rotating member 22 or the driven rotating member 22.

As mentioned above, the support frame 11, in particular a support structure mounted on the support frame 11, is associated with a grip structure for movement and/or climbing in an inclined direction during the ascent or descent of a ramp and/or stairs.

Further, a trigger handle 7 is arranged on the grip structure.

Further, the grip structure may extend and tilt with respect to the length of the support structure of the cart 1.

Further, the trigger handle 7 described above is connected to the braking portion 8 and configured to be switched in the following state.

A rest state of the trigger handle 7, in which the braking portion 8 is in an activated state;

an operating state of the trigger handle 7 in which the braking portion 8 is in a deactivated state.

Further, the trigger handle 7 is disposed on the side of the grip so as to adopt two use states, specifically:

the trigger handle 7 is not operated in a stationary state in which the trigger handle 7 is not subjected to external stress.

In the operating state of the trigger handle 7, the trigger handle 7 is operated for a long time by a pressing force applied to the trigger handle 7 by an operator for a long time in the operating state of the trigger handle 7.

Further, in the case where the operator does not apply pressure or motion to the trigger handle 7, the trigger handle 7 is returned to or kept in an original state, and at this time, the trigger handle 7 is stopped and is in a stationary state of the trigger handle 7.

Further, the trigger handle 7 is connected to the braking portion 8, for example by means of wires or other conventional equivalent structures, acting on the rotating member 22 to brake and/or thus lock the movement of the track structure 2.

Further, in some embodiments, during operation of the track 21, an operator actively depresses the trigger handle 7, causing the trigger handle 7 to operate, thereby braking and/or organizing the rotation of the rotatable member 22, and thus the rotation of the track structure 2; and when the operator releases the trigger handle 7, the trigger handle 7 returns to its rest position. The above-described manner can thus achieve a standstill of the trolley 1 in the case of a transport person transporting the substation equipment on an incline and/or an incline of a staircase.

Further, the cart 1 also includes other arrangements for facilitating movement of the cart 1, such as a grip structure, a cart 1 with a body easily moved in a vertical state, a cart 1 with a body in a horizontal state, and a cart 1 with a body in an inclined state.

Furthermore, the supporting structure of the cart 1 may further provide a box structure for loading substation equipment.

Specifically, the support portion includes at least one support member 82, the support member 82 being mounted on the support frame 11.

Preferably, the above-mentioned braking portion 8 may be partially inserted or housed within the internal profile of the rotating member 22.

Preferably, the braking portion 8 comprises at least a partially curved profile to restore the curvature of the internal profile of the rotating member 22 so as to be able to exert an effective braking action.

Further, the braking portion 8 further comprises a movable engagement member 81, which engagement member 81 is preferably pin-shaped, which is connected to the trigger handle 7, for example by means of a cable (not visible), so that pressing of the trigger handle 7 causes the engagement member 81 to move.

Preferably, the engagement member 81 is a slip fit.

Preferably, the above-mentioned engagement member 81 is mounted and/or supported on a support 82 of the braking portion 8.

Further, the braking portion 8 has an open groove 83, the open groove 83 is formed on the support 82, and the engaging member 81 is mounted inside the open groove 83 and slides along the open groove 83 in a sliding manner.

Preferably, the braking portion body 85 is partially hinged at one end to the support 82 and constrained at the other end to the engagement member 81.

Further, the above-described braking portion 8 further includes a spring 84 having one end connected to the engaging member 81 and the other end restrained to the support 82.

In particular, the spring 84 is associated with the engagement member 81, and thus the braking portion body 85 may push the braking portion body 85 into contact with the inner contour of the rotary 22 under the elastic action of the spring 84, thereby braking or preventing the movement of the rotary 22. When the brake part body 85 is spaced and/or does not act on the inner contour of the rotating member 22, i.e. the brake part body 85 is partly disengaged from the rotating member 22, thereby allowing the rotating member 22 to rotate, and thus the track structure 2 continues to operate.

Further, the spring 84 is loaded or compressed by the movement of the engagement member 81 in the open groove 83, and thus, the elastic action direction of the spring 84 is opposite to the movement direction of the engagement member 81.

Further, the movement is caused by the action of the trigger handle 7.

From the above, it can be conveniently derived that when the trigger handle 7 is pressed and held in the active condition, see fig. 9, the braking portion 8 is in the inactive condition, i.e. the engagement member 81 (which is connected to the trigger handle 7 by a cable or similar means, in contrast to the elastic action of the spring 84) is prepared to slide in the open slot 83 and bring the braking portion body 85 (associated with said engagement member 81) spaced/removed from the internal profile of said rotating member 22, thus allowing free rotation of said rotating member 22 and thus free movement of the track 21 around said rotating member 22. In contrast, when the trigger handle 7 is returned or in a stationary state (see fig. 1), the braking portion 8 is in an activated state, at which time the engaging member 81 slides within the open groove 83 due to the elastic force of the spring 84, the engaging member 81 is attached to the trigger handle 7, for example, by a cable or the like, the braking portion 8 is in contact with the inner contour of the rotating member 22, thereby braking/preventing the rotating member 22 from rotating, and the crawler belt 21 is thus movable around the rotating member 22.

Further, as shown in fig. 5 to 7, the support 82 of the braking portion 8 includes an open groove 83, and the above-mentioned engaging portion is selected from movable pins mounted and slidably supported in the open groove 83.

In fig. 5-7, the deactivated state of the braking portion 8 is illustrated, when the braking portion 8 is in a state allowing the rotation of the rotating member 22 to be free, thereby also causing a movement of the track 21 adapted to be rotated by the rotating member 22. When the trigger handle 7 is pressed, the cable, not visible in the figures, is stretched, moving from the rest position to the active position of the movable pin in the slot 83, compressing the spring 84 and moving the braking portion body 85 away from the inner contour of the rotating member 22, allowing the free rotation of the rotating member 22 and the free movement of the track 21.

When the user releases the trigger handle 7 or in any case when the trigger handle 7 is in a rest state, in which the cable, not visible in the figure, is in a released state or is kept in a rest state, this will move the movable pin in the open slot 83 from the working position to the rest position, thereby releasing the compression amount of the spring 84 (see fig. 7), so that the braking part body 85 approaches the inner contour surface of the rotating member 22, thereby braking the rotation of the rotating member 22 and restricting the movement of the crawler 21.

In particular, the trolley 1 described above can be prepared as an automated operating structure by means of an automated member, a power unit, a control unit and a coupling device applied to the control unit.

In particular, the above-mentioned automation component further comprises a microswitch.

In particular, the power unit preferably comprises a gear motor equipped with a magnetic brake.

In particular, the power unit comprises a housing, inside which there is a battery compartment that can be easily removed from the power unit, said gear motor preferably being equipped with a magnetic brake, with an electronic board having the function of controlling the gear motor, preferably of a type similar to that having a four-quadrant power controller for controlling the gear motor (reference being made in particular to patent publication number CN 1265256C), a transmission joint being keyed to the output shaft of the gear motor to transmit rotation to the motion transmitting member of the track structure 2.

In particular, the power unit may further provide a grip structure so that the grip structure may be removed from the support frame 11.

In particular, the power unit may further provide a connection means in the form of a connection socket to the support frame 11.

In particular, the connection seat is provided on the connection to the support frame 11.

In particular, the power cells may be configured in different modes and different powers as desired.

In particular, the power unit is used to motorized the trolley 1 up and down so that the travel on the stairs is electric rather than manual, which is very advantageous for the operator to move on stairs or general inclines during the lifting phase of the trolley 1.

In particular, the control unit controls the power supply unit so that a user can control the operation of the power supply unit; suitably, the control unit may be connected to the power unit by a cable and be equipped with a potentiometer to adjust the speed of the gearmotor.

In particular, the potentiometer enables PWM modulation of the voltage and has a controlled direction of travel, which is then moved forward/backward using a balance or a proportion of appropriate magnitude.

In particular, in one possible embodiment, the braking action of the trolley 1 when on a slope may be performed by a magnetic brake of the gear motor of the power unit.

Further, these magnetic brakes are deactivated only when a voltage is supplied to the gearmotor and recover immediately after it is removed.

Preferably, the rotating member 22 of the track structure 2 may be automated by means of a drive chain, which in turn is rotatably connected to a coupling housed in the housing of the power unit.

In particular, when automating the trolley 1 using the above-described automation components, the operator ensures that the complete operation of the trolley 1 is controlled by the control unit in combination with the action of the magnetic brake of the gear motor of the power unit, so that each rotating member 22 of the track structure 2 is placed and maintained in a state in which the track 21 is free to rotate.

In particular, the above-mentioned free-rotation condition of the track structure 2 can be carried out in a simple manner by means of the coupling means of the control unit, which are constituted by clips or C-shaped elements connected to the control unit itself.

In particular, said coupling means of the control unit are applied to the trigger handles 7 by pressure, when they are close or possibly close to the working position of the trigger handles 7, achieving a holding of the trolley 1 with the brake part 8 in the deactivated state.

In particular, for safety reasons and to prevent damage to the trolley 1, in the figures in which the power unit is installed, a mechanical microswitch (not visible in the figures) is provided on the support frame 11, which controls the activation/deactivation state of the trigger handle 7 by being directly coupled, by a part, to a cable connected to the trigger handle 7, the other side being connected to a common connection controlling the operation of the power unit. In so doing, the phenomenon that the gear motor is operated by the braking of the braking portion 8 is avoided.

Specifically, the braking portion 8 is in a braking state and the micro switch is in a closed state, so that the gear motor is allowed to move only when the trigger handle 7 is in a pressed state; under other conditions, the microswitch is normally open.

Further, the trolley 1 described above can be used for transportation/movement from horizontal to incline/stairs according to the following method of use (further shown in fig. 8):

the trolley 1 is held by substation equipment for facilitating movement of the trolley 1;

the trolley 1 is tilted by means of wheels 12 to move in a horizontal plane;

the trolley 1 is placed on the tracks 21 of the track structure 2, on an inclined plane/stairs, the trolley 1 will move with or without substation equipment, keeping the trigger handle 7 in a pressed state, allowing free movement of the tracks 21;

if it is intended to stop the trolley 1 on a slope or stairs, the trigger handle 7 is released, so that the trigger handle 7 is moved to a rest position, whereby the above-mentioned braking of the track structure 2 is achieved.

As is clear from the above, the trolley 1 according to the invention allows a safe and flexible transport of substation equipment from ladders of any size or shape, including but not limited to spiral, straight and on substantially horizontal planes.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, or alternatives falling within the spirit and principles of the invention.
