Description

Technical Field

[0001] The present invention relates to the technical field of clamp vehicles, and more particularly to a clamp beam and a clamp vehicle. Background Art

[0002] Clamp trucks are long and large freight railway vehicles with unique over-limit transportation capabilities, and are widely used in the transportation of large and super-large and other unconventional equipment. With the development of heavy industry and railway transportation, the requirements for clamp trucks in railway transportation are getting higher and 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 goods. When the car is running empty, the first half-carriage and the second half-carriage can be connected.

[0004] The structures of the first half car and the second half car are basically the same, and the two are arranged symmetrically. The two generally include a bogie 100, a small chassis 400, a large chassis 200 and a clamp beam 300. The bogie 100 is arranged at the bottom of the small chassis 400, the large chassis 200 is supported on two small chassis 400, and the clamp beam 300 is supported on the large chassis 200. The lower part of the clamp beam 300 has a car ear plate, and the car ear plate and the car ear pin are used to achieve connection with the cargo, so that the cargo is clamped between the clamp beams 300 of the first half car and the second half car.

[0005] like Figure 2 As shown, the clamp beam 300 includes two side beam bodies 301, which are connected to form an integral structure through accessories such as tie rods 303, and each side beam body 301 is welded with a car lug plate 302. The side beam body 301 includes a side beam web 3011, the top of the side beam web 3011 is connected to the side beam top plate, the bottom is connected to the side beam bottom plate 3012, and the end is connected to a plurality of side beam reinforcement plates 3013. In the prior art, the car lug plate 302 is docked on the side beam bottom plate 3012 and the side beam reinforcement plate 3013, and is welded to the side beam bottom plate 3012 and the side beam reinforcement plate 3013. Since the clamp beam 300 is connected to the cargo through the car lug plate 302, the longitudinal beam of the cargo is transferred to the clamp beam 300 through the car lug plate 302. The ear plate 302 is welded to the side beam bottom plate 3012 and the side beam reinforcement plate 3013. The gravity of the cargo needs to be transmitted to the side beam web 3011 of the clamp beam 300 through the side beam bottom plate 3012 and the side beam reinforcement plate 3013. The force transmission path at the ear plate 302 is relatively long. Any problem in any welding node on the force transmission path will cause structural failure of the clamp beam 300.

[0006] Therefore, how to optimize the force transmission path of the car ear plate and improve the reliability of the clamp beam is a problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0007] In view of this, the object of the present invention is to provide a clamp beam to optimize the force transmission path of the car ear plate and improve the reliability of the clamp beam; Another object of the present invention is to provide a clamp vehicle having the clamp beam.

[0008] To achieve the above object, the present invention provides the following technical solutions: A clamp beam, used for clamping a vehicle, comprises two side beam bodies and a vehicle ear plate arranged in parallel, wherein the two side beam bodies are connected by a connecting body; The side beam body includes a side beam web, a side beam bottom plate and a side beam top plate, the side beam bottom plate is arranged at the bottom of the two side beam webs, the side beam top plate is arranged at the top of the two side beam webs, the side beam webs are two steel plate structures arranged in parallel, the lug plates are two steel plate structures respectively connected to the two side beam webs, and the thickness of the lug plates is greater than the thickness of the side beam webs, and the ends of the lug plates are welded to the side beam webs.

[0009] Optionally, in the above-mentioned clamp beam, the side beam body also includes a side beam end plate connected to the end of the side beam web, an insertion opening is formed between the side beam bottom plate and the side beam end plate, the car ear plate is inserted into the insertion opening and welded to the side beam web.

[0014] The clamp beam provided by the present invention has a side beam top plate connected to the upper side of the two side beam webs, and a side beam bottom plate connected to the lower side of the two side beam webs, so that the side beam body forms a stable structure. The two car ear plates are respectively welded to the two side beam webs. When the car ear plates are subjected to force, the force is directly transmitted to the side beam webs through the car ear plates, and no intermediate parts are required for transition. The force transmission path is shorter, which reduces the problem of increased risk of fracture caused by more connection points on the force transmission path due to the longer force transmission path, and improves the safety of the clamp beam.

DETAILED DESCRIPTION

[0023] The core of the present invention is to provide a clamp beam to optimize the force transmission path of the car ear plate and improve the reliability of the clamp beam; Another core of the present invention is to provide a clamp vehicle having the clamp beam.

[0024] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the clamp beam 300 disclosed in the embodiment of the present invention includes two parallel side beam bodies 301 and a car ear plate 302, and the two side beam bodies 301 are connected by a connector. The connector connects the two side beam bodies 301 into a relatively stable whole, so that the clamp beam 300 can stably support the cargo. The lower part of one end of each side beam body 301 is provided with a car ear plate 302, and both ends of the cargo shell are also provided with hinged ear plates corresponding to the car ear plates 302. When the cargo needs to be connected, the hinged ear plate of the cargo is inserted between the two car ear plates 302, and the car ear pin is inserted, so that the cargo and the clamp beam 300 are completed.

[0026] It should be noted that both ends of the cargo are provided with hinged ear plates to be respectively connected to the two clamp beams 300 of the clamping vehicle, so that the cargo is loaded between the two clamp beams 300. At the same time, two hinged ear plates are provided on the left and right sides of the cargo to be respectively connected to the car ear plates 302 of the two side beams 301 of the same clamp beam 300, that is, the front, back, left and right sides of the cargo are connected to the clamping vehicle through four connection points, thereby improving the reliability of cargo fixation.

[0027] The side beam body 301 disclosed in this embodiment includes a side beam web 3011, a side beam bottom plate 3012 and a side beam top plate 3016. The side beam bottom plate 3012 is arranged at the bottom of the two side beam webs 3011, and the side beam top plate 3016 is arranged at the top of the two side beam webs 3011. The side beam webs 3011 are two steel plate structures arranged in parallel. The ear plates 302 are also two steel plate structures and are respectively connected to the two side beam webs 3011. The thickness of the ear plates 302 is greater than that of the side beam webs 3011, and the ends of the ear plates 302 are welded to the side beam webs 3011.

[0028] The clamp beam 300 disclosed in the embodiment of the present invention has a side beam top plate 3016 connected to the upper side of the two side beam webs 3011, and a side beam bottom plate 3012 connected to the lower side of the two side beam webs 3011, so that the side beam body 301 forms a stable structure. The two car ear plates 302 are welded to the two side beam webs 3011 respectively. When the car ear plates 302 are subjected to force, the force is directly transmitted to the side beam webs 3011 through the car ear plates 302, and no intermediate parts are required for transition. The force transmission path is shorter, which reduces the problem of increased risk of fracture caused by more connection points on the force transmission path due to the longer force transmission path, and improves the safety of the clamp beam 300.

[0029] Since the stress-bearing part of the clamp beam 300 is the position of the vehicle ear plate 302, in this embodiment, the side beam body 301 can be designed as a trapezoidal structure, that is, the width of one end of the side beam web 3011 close to the vehicle ear plate 302 is designed to be greater than the width of the other end, so as to ensure that the end connected to the vehicle ear plate 302 has a larger size to ensure sufficient strength.

[0030] In a specific embodiment of the present invention, the side beam body 301 may further include a side beam end plate 3015 connected to the end of the side beam web 3011, and the upper part of the side beam end plate 3015 may also be connected to the side beam top plate 3016. An insertion port is formed between the side beam bottom plate 3012 and the side beam end plate 3015, and the car ear plate 302 is inserted into the insertion port and welded to the side beam web 3011. That is, in this embodiment, the weld 3021 between the side beam web 3011 and the car ear plate 302 is designed within the insertion port. After the car ear plate 302 and the side beam web 3011 are welded, the side wall of the insertion port also has a certain supporting effect on the car ear plate 302, which can improve the reliability of the connection of the car ear plate 302 to a certain extent.

[0031] Further, the end of the side beam bottom plate 3012 is bent to form a bottom plate bent plate, the side beam end plate 3015 is bent to form an end plate bent plate, and an insertion opening is formed between the bottom plate bent plate and the end plate bent plate. The bottom plate bent plate can be formed by bending the main part of the side beam bottom plate 3012 downward, and the end plate bent plate can be formed by bending the main part of the side beam end plate 3015 outward, so that an insertion opening extending obliquely downward is formed between the bottom plate bent plate and the end plate bent plate.

[0032] The sides of the ear plate 302 are respectively fitted with the bottom plate bending plate and the end plate bending plate. After the ear plate 302 is connected to the cargo, the hinge hole of the ear plate 302 is subjected to a downward force, and the bottom plate bending plate and the end plate bending plate both support the ear plate 302, thereby protecting the reliability of the weld 3021 and avoiding the risk of desoldering and fracture.

[0033] In a specific embodiment of the present invention, the side beam web 3011 is formed with a butt end face in the insertion port, and the two ends of the butt end face extend to the side beam bottom plate 3012 and the side beam end plate 3015 respectively, and the end of the car ear plate 302 is welded to the butt end face. In this embodiment, the insertion port is surrounded by the side beam bottom plate 3012 and the side beam end plate 3015, and the width of the withdrawal port can be designed according to the width of the car ear plate 302, so that the car ear plate 302 can be inserted into the insertion port and can be supported on the side beam bottom plate 3012 and the side beam end plate 3015. In order to ensure that the car ear plate 302 can be welded with the side beam web 3011 in the insertion port, in this embodiment, the side beam web 3011 has a portion extending into the insertion port, and the portion forms a butt end face to facilitate the welding of the car ear plate 302 and the side beam web 3011.

[0034] In this embodiment, each plate of the side beam body 301 can be connected by welding to ensure that the side beam body 301 can form a stable overall structure. In order to improve the strength of the two side beam webs 3011, multiple support columns 3014 can be welded between the two side beam webs 3011. In particular, multiple support columns 3014 can be set at the end of the side beam web 3011 with a larger height to prevent the side beam web 3011 from deforming. In addition, multiple side beam reinforcement plates 3013 can be welded between the two side beam webs 3011.

[0035] like Figure 3 As shown, in a specific embodiment of the present invention, the connecting body may include a bolster 304 and an end cross beam 306. The bolster 304 is welded to the first ends of the two side beams 301, and the end cross beam 306 is welded to the second ends of the two side beams 301. The second end of the side beam 301 is an end of the side beam 301 connected to the vehicle ear plate 302. The bolster 304 and the end cross beam 306 may extend from the side beam top plate 3016 to the side beam bottom plate 3012 to ensure a larger connection area with the side beam 301 and improve the strength of the clamp beam 300. It should be noted that the height of the bolster 304 and the end cross beam 306 can also be designed according to demand, and is not limited to the embodiment of extending from the side beam top plate 3016 to the side beam bottom plate 3012.

[0036] The connector disclosed in this embodiment adopts a solution of a pillow block 304 and an end cross beam 306 welded between two side beam bodies 301. Compared with the conventional connection using a tie rod, since there is no need to use a pin shaft to realize the connection process between the tie rod and the side beam body 301, it solves the problem of too many scattered parts in the existing structure and the cumbersome assembly by pin connection, saving time and manpower.

[0037] Furthermore, the connector may further include a middle cross beam 305 and / or a reinforcing cross beam 307 arranged between the bolster 304 and the end cross beam 306. In this embodiment, a number of middle cross beams 305 and / or reinforcing cross beams 307 may be arranged on the bolster 304 and the end cross beam 306 according to needs, the middle cross beam 305 may be an I-beam, and the middle cross beam 305 and the reinforcing cross beam 307 may be welded to one side close to the top plate 3016 of the side beam.

[0038] like Figure 1 As shown, an embodiment of the present invention discloses a clamping vehicle, which includes a chassis and a clamping beam 300. The chassis may include a large chassis 200 and a small chassis 400. The clamping beam 300 is arranged on the chassis (which may be the large chassis 200), and the clamping beam 300 is the clamping beam 300 disclosed in the above embodiment. Since the clamping beam 300 is provided, all the technical effects of the clamping beam 300 are combined, and will not be repeated herein.

[0039] When loading and unloading, the clamp car needs to separate the first half car from the second half car. Since the loading and unloading time is long, the traction locomotive cannot wait for a long time to perform the tamping operation for the clamp car. When loading and unloading, the first half car and the second half car need to be pushed repeatedly to adjust the distance between the first half car and the second half car. Since the first half car and the second half car are heavy, a lot of manpower is needed to push them to move without the help of a traction locomotive; or other traction vehicles are rented to tow the first half car and the second half car, resulting in high loading and unloading costs.

[0040] Based on this, Figure 5-Figure 7 As shown, the clamping vehicle disclosed in the embodiment of the present invention may also include an auxiliary cart device 500 to save manpower and other tractor rental costs, and save the cost of loading and unloading vehicles. The auxiliary cart device 500 includes a mounting seat 502 and a cart telescopic device 501.

[0041] The mounting seat 502 is fixed on the base frame (e.g., the large base frame 200), and the mounting seat 502 provides a mounting base for the cart telescopic device 501. One end of the cart telescopic device 501 is hinged on the mounting seat 502, and the other end is a ground-supporting thrust output end. When in use, the ground-supporting thrust output end acts on the force-bearing part. For example, the ground-supporting thrust output end can be abutted against the force-applying position, such as the ground or other fixed parts that can be used as the force-applying body, and are not limited to the ground.

[0042] The trolley 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.

[0043] 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 improve the convenience of operation. The operator can control the extension and shortening of the cart telescopic device 501 by pressing the buttons of the remote control. After the cart telescopic device 501 is shortened, the operator only needs to rotate the cart telescopic device 501 to the corresponding angle (usually, the angle of the cart telescopic device 501 does not require the operator to assist in rotating. When the cart telescopic device 501 is shortened, it will automatically rotate to the angle where its ground-supporting thrust output end touches the ground under its own gravity. Only when the length of the cart telescopic device 501 is less than the distance from the ground, the operator needs to assist in swinging the angle of the cart telescopic device 501 so that it can touch the ground at an inclined angle), and ensure that the ground-supporting thrust output end touches the ground, and then control the extension of the cart telescopic device 501 by pressing the buttons of the remote control. Repeating the operation in sequence can achieve the pushing of the vehicle.

[0044] In order to facilitate the articulation of the cart telescopic device 501 and the mounting seat 502, a hinge support 5021 is provided on the mounting seat, and a hinge lug 5012 is provided at one end of the cart telescopic device 501. The hinge lug 5012 is articulated with the hinge support 5021 via a hinge axis. The cart telescopic device 501 can rotate along the hinge axis, so that the ground-supporting thrust output end can be supported on the force-bearing part (such as the ground) through 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 becomes longer, 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 becomes longer, thereby generating a thrust to push the vehicle to the right, and then the vehicle can move forward to the right.

[0045] like Figure 8 As shown, the auxiliary cart device 500 disclosed in this embodiment can assist the clamping trolley to move in both left and right directions. When the auxiliary clamping trolley moves forward to the left, the cart telescopic device 501 rotates to the lower right, and the ground-supporting thrust output end of the cart telescopic device 501 extends and pushes against the ground. The telescopic rod of the cart telescopic device 501 continues to extend, pushing the clamping trolley forward a distance to the left. After the telescopic rod of the cart telescopic device 501 is retracted to a certain length, the ground-supporting thrust output end is pushed to the ground, and then the telescopic rod is extended again, pushing the clamping trolley forward again, and the clamping trolley is repeatedly moved back and forth, and the clamping trolley continues to move forward to the left.

[0046] like Fig. 9 As shown, when the auxiliary clamping trolley moves to the right, the trolley telescopic device 501 rotates to the lower left, and the ground-supporting thrust output end of the trolley telescopic device 501 extends and pushes against the ground. The telescopic rod of the trolley telescopic device 501 continues to extend, pushing the clamping trolley to the right for a distance. After the telescopic rod of the trolley telescopic device 501 is retracted to a certain length, the ground-supporting thrust output end is pushed against the ground, and then the telescopic rod is extended again, pushing the clamping trolley forward again, and the clamping trolley is repeatedly moved back and forth, and the clamping trolley continues to move to the right.

[0047] The present invention uses the cart telescopic device 501 to control the clamping cart to move forward left and right, without the need for manual operation or the use of a traction vehicle or other vehicle, thereby improving the convenience and safety of the operation. At the same time, a large amount of personnel costs and the cost of renting a traction vehicle are saved.

[0048] 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 hinged to the ground-supporting thrust output end. In this embodiment, the ground-supporting support 5011 is hinged to the ground-supporting thrust output end, so that 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, so as to increase the contact area between the ground-supporting support 5011 and the ground, improve the friction, and prevent slipping with the ground during the cart pushing process.

[0049] Those skilled in the art can understand that the larger the ground contact area of ​​the ground support 5011, the greater the friction force, and the less likely it is to fail due to slipping when a large thrust is generated. Those skilled in the art can select the ground contact area of ​​the ground support 5011 according to the application scenario of the auxiliary cart device 500 and the vehicle used, so as to reduce the floor space of the ground support 5011 while satisfying the friction force.

[0050] like Figure 8 As shown, in order to further improve the gripping force of the ground-supporting support 5011, in this embodiment, the ground-supporting support 5011 has a ground-supporting surface, which is a surface that fits on the ground. The ground-supporting surface is provided with a gripping portion 5013. After the ground-supporting surface of the ground-supporting support 5011 is supported on the ground, the gripping portion 5013 can be inserted under the ground, thereby improving the friction between the ground-supporting support 5011 and the ground, further improving the gripping force, and preventing slipping during operation.

[0051] Furthermore, the gripping portion 5013 may include a plurality of inserting plates spaced apart on the supporting surface. The inserting plates may be disposed perpendicularly to the supporting surface or inclined relative to the supporting surface. Figure 8 The solution shown is that the inserted floor and the supporting ground are inclined at a certain angle.

[0052] When the inserting floor is arranged vertically with 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. The gripping part 5013 arranged vertically with the supporting ground is inserted under the ground by external force, so as to achieve the effect of fixing the telescopic device 501 on the ground. However, this method requires the operator to insert the gripping part 5013 under the ground by external force, which will inevitably affect the walking efficiency of the vehicle.

[0053] When the inserted floor is tilted at a certain angle to the supporting ground, there is no need for the operator to insert the gripping portion 5013 under the ground by external force. Specifically, when the inserted 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 inserted floor should be adjusted to be tilted 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 side compared to the upper end, the lower end of the inserted floor should also be tilted to the right side compared to the upper end. With this arrangement, when the telescopic rod of the cart telescopic device 501 is extended, making the cart telescopic device 501 longer, the inserted floor can be automatically inserted under the ground without the operator applying external force to perform this operation.

[0054] Since the cylinder body and the 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 arranged on the cylinder body, and the other is arranged on the telescopic rod, so that when the telescopic rod is telescopic, the distance between the hinged ear plate 5012 and the ground support 5011 can be changed. Since the cylinder body and the telescopic rod can rotate relative to each other, the ground support 5011 can be rotated according to demand, so as to adjust the inclination direction of the plug-in floor, so that the plug-in floor can be inclined in the same direction as the cart telescopic device 501.

[0055] The number and spacing of the plug-in 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.

[0056] In addition, the gripping part 5013 may also include a plurality of ground-inserting spikes arranged at intervals on the supporting ground surface. The ground-inserting spikes are different from the ground-inserting floor surface in that the ground-inserting floor surface is a plate structure, while the ground-inserting spikes are a rod structure. It should be noted that both the ground-inserting floor surface with a rod structure and the ground-inserting spikes with a rod structure can be inserted under the ground to enhance the gripping force of the supporting ground support 5011 and prevent slipping. The ground-inserting spikes can also be arranged in the same manner as the ground-inserting floor surface, for example, they can be perpendicular or inclined to the supporting ground surface.

[0057] Furthermore, the gripping portion 5013 may also include friction patterns arranged at intervals on the supporting ground surface. The friction patterns can increase the friction between the supporting base 5011 and the ground surface, and can also prevent slipping to a certain extent. It can be understood by those skilled in the art that the gripping portion 5013 may include a ground plate, ground spikes, and friction patterns at the same time, or may include only one or both of them.

[0058] The thrust generated by the cart telescopic device 501 acts on the vehicle to be pushed through the mounting seat 502, thereby enabling the vehicle to be pushed to move. In particular, for a heavy vehicle to be pushed, a large thrust is required, so the mounting seat 502 needs to have sufficient connection strength to prevent the mounting seat 502 from being desoldered and broken due to the large thrust required when the cart telescopic device 501 assists in pushing the cart.

[0059] like Figure 7 As shown, in this embodiment, the mounting seat 502 may include a mounting seat body and an oblique support body. The mounting seat body is fixed on the base frame, and one end of the trolley telescopic device 501 is hinged on the mounting seat body. Specifically, one end of the trolley telescopic device 501 may be hinged to the lower side of the mounting seat body, that is, the hinge support 5021 is fixed to the lower side of the mounting seat body.

[0060] The oblique support body is connected to the mounting seat body and the vehicle to be pushed respectively. The oblique support body can be a triangular plate body, one side of which can be welded to the upper surface of the mounting seat body, and the other side can be welded to the chassis of the clamp vehicle.

[0061] 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, and fasteners can also be used for fixing), so that it has greater connection strength and prevents the problem of breakage at the connection.

[0062] The trolley telescopic device 501 is used only when it is needed to push the clamping trolley to move, and is idle at other times. In order to store the trolley telescopic device 501 when it is idle, in this embodiment, the auxiliary trolley device 500 may also include an idle bracket 504, which is used to be fixed on the chassis, and the idle bracket 504 has a supporting portion for supporting the trolley telescopic device 501. The supporting portion may be a card slot with an opening facing upward, through which the trolley telescopic device 501 can be clamped, preventing the trolley telescopic device 501 from detaching from the idle bracket 504, thereby improving the reliability of the idle bracket 504 fixing the trolley telescopic device 501. It should be noted that the idle bracket 504 can also fix the trolley telescopic device 501 in other ways, not limited to the card slot.

[0063] When the clamping vehicle is driving normally, that is, when the auxiliary trolley device 500 is not needed to assist in walking, the trolley telescopic device 501 can be fixed on the idle bracket 504 to prevent the trolley telescopic device 501 from swinging back and forth and colliding with surrounding objects when the clamping vehicle is driving normally, thereby causing damage to the surrounding objects and the trolley telescopic device 501 itself. In this embodiment, the trolley telescopic device 501 is fixed by the idle bracket 504, which can restrain the trolley telescopic device 501 from swinging uncontrollably and randomly.

[0064] When the auxiliary trolley device 500 is needed to assist in pushing the clamping trolley to move, it is only necessary to remove the trolley telescopic device 501 from the idle bracket 504 .

[0065] Since the mounting seat 502 will protrude from the body of the clamping vehicle, and the mounting seat 502 is usually a rectangular plate structure, the edges and corners are relatively sharp, which is easy to hit the operator. Based on this, the auxiliary cart device 500 disclosed in this embodiment may also include a guardrail 503, which is fixed to the base frame and surrounded by the outer side of the mounting seat 502. The guardrail 503 should be formed by bending a relatively rounded rod body, or a box body structure can be used to surround the mounting seat 502 inside. In short, as long as the sharp part of the mounting seat 502 can be prevented from hitting the operator, it will be fine.

[0066] In addition, in order to ensure that the auxiliary trolley device 500 can provide a relatively stable thrust for the clamping trolley, auxiliary trolley devices 500 are provided on both sides of the base frame.
