Description

Technical Field

[0001] The utility model relates to the technical field of clamping carts, and more particularly to an auxiliary cart device and a clamping cart. Background Art

[0002] Clamp trucks are long freight railcars with unique oversized transport capabilities. They are widely used to transport large and ultra-large equipment. With the development of heavy industry and railway transportation, the requirements for clamp trucks in railway transportation are becoming increasingly higher.

[0003] like Figure 1 As shown, the clamp car has two half-carriages. For ease of understanding, the two half-carriages are defined as the first half-carriage and the second half-carriage respectively. The first half-carriage and the second half-carriage are used to load cargo. When the car is running empty, the first half-carriage and the second half-carriage can be connected.

[0004] The first and second half car sections have essentially the same structure and are arranged symmetrically. They generally consist of a bogie 100, a small underframe 400, a large underframe 200, and a clamping beam 300. The bogie 100 is mounted on the bottom of the small underframe 400, the large underframe 200 is supported on two small underframes 400, and the clamping beam 300 is supported on the large underframe 200. The clamping beam 300 has a lug plate at its lower portion. This lug plate and lug pin connect the cargo to the cargo, thereby clamping the cargo between the clamping beam 300 of the first and second half car sections.

[0005] When loading and unloading, the clamp truck needs to separate the first half of the car from the second half. Due to the long loading and unloading time, the traction locomotive cannot wait for a long time to perform the clamp truck ramming operation, which often requires a large amount of manpower or the rental of other tractors to perform the vehicle ramming operation, resulting in high loading and unloading costs.

[0006] Therefore, how to save manpower and rental fees of other tractors and save the cost of loading and unloading vehicles is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0007] In view of this, the purpose of the present invention is to provide an auxiliary cart pushing device to save manpower and other tractor rental costs, and save the cost of loading and unloading the cart;

[0008] Another object of the present invention is to provide a clamping cart with the auxiliary cart device.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] An auxiliary pushing device for assisting a vehicle to be pushed in moving, comprising:

[0011] A mounting base, used for fixing on the vehicle to be pushed;

[0012] The cart telescopic device has one end hinged on the mounting seat and the other end being a ground-supporting thrust output end. When in use, the ground-supporting thrust output end acts on the force-bearing part.

[0013] Optionally, in the above auxiliary cart device, the ground-supporting thrust output end is provided with a ground-supporting support, and the ground-supporting support is hinged to the ground-supporting thrust output end.

[0014] Optionally, in the auxiliary cart device, the ground-supporting support has a ground-supporting surface, and a gripping portion is provided on the ground-supporting surface.

[0015] Optionally, in the auxiliary cart device, the gripping portion includes a plurality of inserting floors spaced apart on the supporting floor surface; and / or,

[0016] The gripping portion includes a plurality of ground-inserting spikes arranged at intervals on the supporting surface; and / or,

[0017] The gripping portion includes friction lines arranged at intervals on the supporting surface.

[0018] Optionally, in the auxiliary cart device, the mounting seat includes:

[0019] A mounting seat body is used to be fixed on the vehicle to be pushed, and one end of the cart telescopic device is hinged to the mounting seat body;

[0020] The oblique support body is respectively connected to the mounting seat body and the vehicle to be pushed.

[0021] Optionally, the auxiliary cart device further includes an idle bracket, which is used to be fixed on the vehicle to be pushed, and the idle bracket has a supporting portion for supporting the cart telescopic device.

[0022] Optionally, in the above auxiliary cart device, the supporting portion is a slot with an opening facing upward.

[0023] Optionally, the auxiliary cart device further includes a guardrail, which is used to be fixed on the vehicle to be pushed and is arranged around the outer side of the mounting seat.

[0024] The auxiliary pusher device provided by the utility model can assist a vehicle to be pushed in both left and right directions. When assisting the vehicle to be pushed to the left, the pusher telescopic device rotates to the lower right, and the ground-supporting thrust output end of the pusher telescopic device extends and touches the ground. The telescopic rod of the pusher telescopic device further extends, pushing the vehicle forward a certain distance to the left. After the telescopic rod of the pusher telescopic device is partially retracted, the ground-supporting thrust output end is again pressed against the ground, and then the telescopic rod is further extended, pushing the vehicle forward again. This reciprocating cycle allows the vehicle to continue to move forward to the left.

[0025] To assist the vehicle in moving to the right, the telescopic mechanism rotates downward and left, extending the ground-supporting thrust output end of the mechanism and resting it on the ground. The telescopic rod of the mechanism then extends further, pushing the vehicle a certain distance to the right. After the rod retracts partially, the ground-supporting thrust output end rests on the ground, and the rod is extended again, further pushing the vehicle forward. This cycle repeats until the vehicle continues to move to the right.

[0026] The utility model controls the vehicle's left and right forward movement by pushing the telescopic device, which does not require manual operation or the use of a traction vehicle, thereby improving the convenience and safety of operation. At the same time, it saves a lot of personnel costs and the cost of renting a traction vehicle.

[0045] The core of this utility model is to provide an auxiliary cart pushing device to save manpower and other tractor rental costs, saving the cost of loading and unloading the cart;

[0046] Another core of the present invention is to provide a clamping cart with the auxiliary cart device.

[0047] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0048] When loading and unloading, the clamp truck needs to separate the first and second car sections. Due to the long loading and unloading times, the traction locomotive cannot wait for long periods of time to allow the clamp truck to move. During loading and unloading, the first and second car sections must be moved back and forth to adjust the distance between them. Because the first and second car sections are heavy, moving them without the aid of a traction locomotive requires significant manpower. Alternatively, a separate traction vehicle may be required to pull the first and second car sections, resulting in high loading and unloading costs.

[0049] Based on this, the embodiment of the present utility model discloses an auxiliary cart device to save manpower and rental costs of other tractors, and save the cost of loading and unloading carts.

[0050] like Figure 1-Figure 4 As shown, the auxiliary cart device 500 disclosed in the embodiment of the present invention is used to assist the vehicle to be pushed in moving. It should be noted that the application scenario of the auxiliary cart device 500 is not limited to the clamping vehicle. All vehicles that do not have traction power and require external equipment or human traction can use the auxiliary cart device 500 to assist in pushing the vehicle to move and change the position of the vehicle.

[0051] The auxiliary cart device 500 disclosed in this embodiment of the utility model includes a mounting base 502 and a cart telescopic device 501. The mounting base 502 is used to be fixed to the vehicle to be pushed. If the vehicle to be pushed is a clamping vehicle, the mounting base 502 can be fixed to the frame of the clamping vehicle, for example, the mounting base 502 can be fixed to the large base frame 200 or the small base frame 400. The mounting base 502 provides a mounting base for the cart telescopic device 501.

[0052] One end of the cart telescopic device 501 is hinged to the mounting base 502, and the other end serves as a ground-supporting thrust output terminal. When in use, the ground-supporting thrust output terminal acts on a force-receiving location. For example, the ground-supporting thrust output terminal can be connected to a force-applying location, such as the ground or another immovable location, to serve as the main force-applying location, not limited to the ground.

[0053] The cart telescopic device 501 can be any device that can change its length by extending and shortening, including but not limited to a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc.

[0054] It should be noted that the extension and retraction of the telescopic rod of the cart telescopic device 501 can be controlled by a remote control to enhance operational convenience. The operator can control the extension and retraction of the cart telescopic device 501 using buttons on the remote control. After the cart telescopic device 501 is retracted, the operator simply rotates the cart telescopic device 501 to the appropriate angle, ensuring that the ground-supporting thrust output end touches the ground. The operator then controls the extension of the cart telescopic device 501 using the buttons on the remote control. Repeating this operation can achieve propulsion of the vehicle.

[0055] To facilitate the articulation between the cart telescopic device 501 and the mounting base 502, a hinge support 5021 is provided on the mounting base. A hinge lug 5012 is provided at one end of the cart telescopic device 501. The hinge lug 5012 is hingedly connected to the hinge support 5021 via a hinge axis. The cart telescopic device 501 can rotate along the hinge axis, allowing the ground-supporting thrust output end to be supported on a force-bearing location (e.g., the ground) by the rotation of the cart telescopic device 501. When the vehicle needs to be pushed to the left, the ground-supporting thrust output end can be supported on the ground and located on the right side of the hinge shaft. By controlling the telescopic rod of the trolley telescopic device 501 to extend, the overall length of the trolley telescopic device 501 is lengthened, thereby generating a thrust to push the vehicle to the left, and then the vehicle can move forward to the left; similarly, when the vehicle needs to be pushed to the right, the ground-supporting thrust output end can be supported on the ground and located on the left side of the hinge shaft. By controlling the telescopic rod of the trolley telescopic device 501 to extend, the overall length of the trolley telescopic device 501 is lengthened, thereby generating a thrust to push the vehicle to the right, and then the vehicle can move forward to the right.

[0056] like Figure 5 As shown, the auxiliary pusher device 500 provided by the present invention can assist the vehicle to be pushed in both left and right directions. When assisting the vehicle to be pushed to the left, the pusher telescopic device 501 rotates to the lower right, and the ground-supporting thrust output end of the pusher telescopic device 501 extends and touches the ground. The telescopic rod of the pusher telescopic device 501 continues to extend, pushing the vehicle forward a distance to the left. After the telescopic rod of the pusher telescopic device 501 is partially retracted, the ground-supporting thrust output end is again pressed against the ground, and then the telescopic rod is further extended, pushing the vehicle forward again. This reciprocating cycle continues, and the vehicle continues to move forward to the left.

[0057] like Figure 6As shown, when assisting the vehicle to be pushed to the right, the cart telescopic device 501 rotates downward and leftward, and the ground-supporting thrust output end of the cart telescopic device 501 extends and touches the ground. The telescopic rod of the cart telescopic device 501 further extends, pushing the vehicle forward a certain distance to the right. After the telescopic rod of the cart telescopic device 501 retracts partially, the ground-supporting thrust output end touches the ground again, and then the telescopic rod is further extended, pushing the vehicle forward again. This reciprocating cycle continues, and the vehicle continues to move to the right.

[0058] The utility model controls the left and right forward movement of the vehicle by using the pusher telescopic device 501, which does not require manual operation or the use of a traction vehicle, thereby improving the convenience and safety of operation and saving a lot of labor costs and the cost of renting a traction vehicle.

[0059] In order to increase the area of ​​the ground-supporting thrust output end acting on the ground, in this embodiment, a ground-supporting support 5011 is provided at the ground-supporting thrust output end, and the ground-supporting support 5011 is hingedly connected to the ground-supporting thrust output end. In this embodiment, the ground-supporting support 5011 is hingedly connected to the ground-supporting thrust output end. Therefore, the angle between the ground-supporting support 5011 and the cart telescopic device 501 can be adjusted according to the angle between the ground and the cart telescopic device 501, so that the bottom surface of the ground-supporting support 5011 can be parallel to the ground and supported on the ground, thereby increasing the contact area between the ground-supporting support 5011 and the ground, improving friction, and preventing slipping on the ground during the cart pushing process.

[0060] Those skilled in the art will appreciate that the larger the ground contact area of ​​the support bracket 5011, the greater the friction, and the less likely it is to slip and fail when a large thrust is generated. Those skilled in the art can select the ground contact area of ​​the support bracket 5011 based on the application scenario of the auxiliary cart device 500 and the vehicle in which it is used, so as to reduce the footprint of the support bracket 5011 while still meeting the required friction.

[0061] like Figure 5 As shown, in order to further improve the grip of the ground-supporting support 5011, in this embodiment, the ground-supporting support 5011 has a support surface, which is a surface that contacts the ground. The support surface is provided with a gripping portion 5013. After the support surface of the ground-supporting support 5011 contacts the ground, the gripping portion 5013 can be inserted under the ground, thereby increasing the friction between the ground-supporting support 5011 and the ground, further improving the grip and preventing slipping during operation.

[0062] Furthermore, the gripping portion 5013 may include a plurality of inserting plates spaced apart on the supporting surface. The inserting plates may be disposed perpendicular to the supporting surface or inclined relative to the supporting surface. Figure 5 In the solution shown, the inserting floor and the supporting ground are inclined at a certain angle.

[0063] When the inserting floor is perpendicular to the supporting floor, and the pusher device 500 is needed to assist in pushing the vehicle, the pusher telescopic device 501 is rotated to a certain angle relative to the ground, and the supporting support 5011 is placed on the ground. The gripping portion 5013, which is perpendicular to the supporting floor, is then inserted into the ground using external force, thereby securing the telescopic device 501 to the ground. However, this method requires the operator to insert the gripping portion 5013 into the ground using external force, which inevitably affects the vehicle's travel efficiency.

[0064] If the inserting floor is tilted at a certain angle to the supporting ground, the operator does not need to use external force to insert the gripping portion 5013 under the ground. Specifically, when the inserting floor is tilted to the supporting ground, when the auxiliary cart device 500 is needed to assist in pushing the vehicle to walk, the cart telescopic device 501 is rotated to a certain angle relative to the ground, and the supporting support 5011 is placed on the ground. It should be noted that the inserting floor should be adjusted to tilt in the same direction as the cart telescopic device 501. For example, when the lower end of the telescopic device 501 is tilted to the right compared to the upper end, the lower end of the inserting floor should also be tilted to the right compared to the upper end. With this arrangement, when the telescopic rod of the cart telescopic device 501 is extended, causing the cart telescopic device 501 to become longer, the inserting floor can be automatically inserted under the ground without the operator applying external force to perform this operation.

[0065] Because the cylinder and telescopic rod of the cart telescopic device 501 can rotate relative to each other, one of the hinged ear plate 5012 and the ground support 5011 is disposed on the cylinder, and the other is disposed on the telescopic rod. As the telescopic rod is extended or retracted, the distance between the hinged ear plate 5012 and the ground support 5011 can be changed. Furthermore, because the cylinder and telescopic rod can rotate relative to each other, the ground support 5011 can be rotated as needed to adjust the inclination direction of the insert floor, so that the insert floor can tilt in the same direction as the cart telescopic device 501.

[0066] The number and spacing of the insert floors can be selected by those skilled in the art according to the application scenario and are not limited to the method shown in the figure.

[0067] Furthermore, the gripping portion 5013 may also include a plurality of ground spikes spaced apart on the support surface. These spikes differ from the floorboards in that the floorboards are plate-like structures, while the spikes are rod-like structures. It should be noted that both the floorboards and the ground spikes can be inserted into the ground, enhancing the grip of the support 5011 and preventing slipping. The ground spikes can also be arranged similarly to the floorboards, for example, perpendicular to or at an angle to the support surface.

[0068] Furthermore, the gripping portion 5013 may also include friction grooves spaced apart on the supporting surface. The friction grooves can increase the friction between the supporting base 5011 and the ground, and can also prevent slipping to a certain extent. Those skilled in the art will appreciate that the gripping portion 5013 may include a plurality of inserts, inserting spikes, and friction grooves, or may include only one or both of these.

[0069] The thrust generated by the cart telescopic device 501 acts on the vehicle to be pushed through the mounting base 502, thereby enabling the vehicle to move. Especially for heavier vehicles, the required thrust is greater, so the mounting base 502 needs to have sufficient connection strength to prevent the mounting base 502 from becoming unsoldered and broken due to the large thrust required when the cart telescopic device 501 assists in pushing the cart.

[0070] like Figure 4 As shown, in this embodiment, the mounting base 502 may include a mounting base body and an oblique support body. The mounting base body is used to be fixed to the vehicle to be pushed, and one end of the cart telescopic device 501 is hinged to the mounting base body. Specifically, one end of the cart telescopic device 501 may be hinged to the lower side of the mounting base body, that is, the hinge support 5021 is fixed to the lower side of the mounting base body.

[0071] The oblique support body is respectively connected to the mounting base body and the vehicle to be pushed. The oblique support body can be a triangular plate body, one side of the oblique support body can be welded to the upper surface of the mounting base body, and the other side can be welded to the vehicle to be pushed.

[0072] In this embodiment, the mounting base 502 is designed to have an inclined support body in addition to the mounting base body. The inclined support body increases the connection area between the mounting base 502 and the vehicle to be pushed (for example, the welding area, which can also be fixed with fasteners), thereby having greater connection strength and preventing the problem of breakage at the connection.

[0073] The cart telescopic device 501 is only used when it is needed to push the vehicle and is idle the rest of the time. To store the cart telescopic device 501 when it is not in use, in this embodiment, the auxiliary cart device 500 may further include an idle bracket 504. The idle bracket 504 is used to be fixed to the vehicle to be pushed. The idle bracket 504 has a support portion for supporting the cart telescopic device 501. The support portion may be a slot with an upward opening, through which the cart telescopic device 501 can be engaged, preventing the cart telescopic device 501 from detaching from the idle bracket 504, thereby improving the reliability of the idle bracket 504 in fixing the cart telescopic device 501. It should be noted that the idle bracket 504 can also be used to fix the cart telescopic device 501 in other ways, and is not limited to the slot method.

[0074] During normal vehicle travel, i.e., when the auxiliary pusher device 500 is not required for assistance, the pusher telescopic device 501 can be fixed to the idle bracket 504. This prevents the pusher telescopic device 501 from swinging back and forth during normal vehicle travel, colliding with surrounding objects, and causing damage to the surrounding objects and the pusher telescopic device 501 itself, as the pusher telescopic device 501 is only fixed to the mounting base 502 by a hinged connection. In this embodiment, the use of the idle bracket 504 to fix the pusher telescopic device 501 can restrain the pusher telescopic device 501 from swinging uncontrollably.

[0075] When the auxiliary pusher device 500 is needed to assist in pushing the vehicle, it is only necessary to remove the pusher telescopic device 501 from the idle bracket 504.

[0076] Because the mounting base 502 protrudes from the vehicle's body and is typically a rectangular plate structure, its edges and corners are relatively sharp and can easily strike the operator. Therefore, the auxiliary cart device 500 disclosed in this embodiment may further include a guardrail 503, which is used to be fixed to the vehicle to be pushed and is disposed around the outside of the mounting base 502. The guardrail 503 should be formed by bending a relatively rounded rod, or it can be a box structure with the mounting base 502 disposed inside. In short, as long as it can prevent the sharp parts of the mounting base 502 from striking the operator, it is sufficient.

[0077] The present invention also discloses a clamping vehicle, comprising a first half-carriage and a second half-carriage, each of which includes a chassis and an auxiliary pusher device 500. The auxiliary pusher device 500 is disposed on the chassis, and the auxiliary pusher device 500 is the auxiliary pusher device 500 disclosed in the above embodiment. The chassis can be a large chassis 200 or a small chassis 400. To ensure that the auxiliary pusher device 500 can provide a relatively stable thrust for the clamping vehicle, auxiliary pusher devices 500 can be disposed on both sides of the chassis of the first half-carriage and the second half-carriage.

[0078] The clamping cart disclosed in the embodiment of the present invention has all the technical effects of the auxiliary cart device 500 , and thus will not be described in detail herein.
