Abstract

Disclosed in the present invention are a Schnabel beam and a Schnabel car. The Schnabel beam comprises two side beam bodies arranged in parallel and two ear plates arranged in parallel, and the two side beam bodies are connected by means of a connecting body. The side beam bodies comprise side beam web plates, 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 web plates, the side beam top plate is arranged at the top of the two side beam web plates, and the side beam web plates are two plates arranged in parallel; and the ear plates are two plates respectively connected to the two side beam web plates, and ends of the ear plates are welded to the side beam web plates. The two ear plates of the present invention are respectively welded to the two side beam web plates. When the ear plates are subjected to force, an acting force is directly transmitted to the side beam web plates by means of the corresponding ear plates, and an intermediate member is not required for transition, resulting in a short force transmission path, thereby reducing the problem of an increased risk of fracture caused by a large number of connecting points on a long force transmission path, and improving the use safety of the Schnabel beam.

Description

A clamp-shaped beam and clamping vehicle

[0001] This application claims priority to Chinese Patent Application No. 202411825540.3, filed on December 11, 2024, entitled "A Clamping Beam and Clamping Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of clamping cart technology, and more specifically, to a clamp-shaped beam and a clamping cart. Background Technology

[0003] Clamp cars are long and heavy freight railway cars with unique oversized transport capabilities, widely used in the transportation of large, extra-large, and other unconventional equipment. With the development of heavy industry and railway transportation, the requirements for clamp cars in railway transportation are becoming increasingly stringent.

[0004] As shown in Figure 1, the clamping vehicle has two half-cars. For ease of understanding, the two half-cars are defined as the first half-car and the second half-car. The first half-car and the second half-car are used to load goods. When the vehicle is running empty, the first half-car and the second half-car can be connected.

[0005] The first and second half-cars have essentially the same structure and are arranged symmetrically. They generally include a bogie 100, a small underframe 400, a large underframe 200, and a clamp beam 300. The bogie 100 is located at the bottom of the small underframe 400, the large underframe 200 is supported by the two small underframes 400, and the clamp beam 300 is supported by the large underframe 200. The lower part of the clamp beam 300 has a lug plate, which, along with lug pins, connects to the cargo, thus clamping the cargo between the clamp beams 300 of the first and second half-cars.

[0006] As shown in Figure 2, the clamp-shaped beam 300 includes two side beams 301, which are connected by tie rods 303 and other accessories to form an integral structure. Each side beam 301 is welded with a lug plate 302. Each side beam 301 includes a side beam web 3011, with a top plate connected to the top of the web 3011, a bottom plate 3012 connected to the bottom, and several reinforcing plates 3013 connected to the ends. In the prior art, the lug plates 302 are mated to the bottom plate 3012 and the reinforcing plates 3013, and welded to them. Since the clamp-shaped beam 300 is connected to the cargo via the lug plates 302, the longitudinal beams of the cargo are transferred to the clamp-shaped beam 300 through the lug plates 302. The ear plate 302 is welded to the side beam bottom plate 3012 and the side beam reinforcing plate 3013. The weight of the cargo also needs to be transmitted to the side beam web plate 3011 of the clamp beam 300 through the side beam bottom plate 3012 and the side beam reinforcing plate 3013. The force transmission path at the ear plate 302 is relatively long. If any welding node on the force transmission path has a problem, it will lead to the structural failure of the clamp beam 300.

[0007] Therefore, optimizing the force transmission path of the wheel lugs and improving the reliability of the clamp beam are problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a clamp-shaped beam to optimize the force transmission path of the car ear plate and improve the reliability of the clamp-shaped beam.

[0009] Another object of the present invention is to provide a clamping vehicle having the above-mentioned clamp-shaped beam.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A clamp-shaped beam for clamping a vehicle includes two parallel side beams and a lug plate, wherein the two side beams are connected by a connector.

[0012] The side beam 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, and the side beam top plate is arranged at the top of the two side beam webs. The side beam web is a structure of two parallel steel plates. The lug plate is a structure of two steel plates that are respectively connected to the two side beam webs, and the thickness of the lug plate is greater than the thickness of the side beam web. The ends of the lug plates are welded to the side beam web.

[0013] Optionally, in the above-mentioned clamp-shaped beam, the side beam body further includes a side beam end plate connected to the end of the side beam web, an insertion port is formed between the side beam bottom plate and the side beam end plate, the wheel plate is inserted into the insertion port and welded to the side beam web.

[0014] Optionally, in the above-mentioned clamp-shaped beam, the end of the side beam bottom plate is bent to form a bottom plate bending plate, the side beam end plate is bent to form an end plate bending plate, and the insertion port is formed between the bottom plate bending plate and the end plate bending plate;

[0015] The sides of the wheel panel are respectively attached to the bottom plate bending plate and the end plate bending plate.

[0016] Optionally, in the above-mentioned clamp-shaped beam, the web of the side beam has a mating end face formed in the insertion port, and the two ends of the mating end face extend to the bottom plate of the side beam and the end plate of the side beam, respectively.

[0017] The end of the wheel plate is welded to the mating end face.

[0018] Optionally, in the above-mentioned clamp-shaped beam, the connecting body includes:

[0019] The bolster beam is welded to the first end of the two side beams;

[0020] An end beam is welded to the second end of the two side beams, the second end of which is the end of the side beam that connects to the wheel plate.

[0021] Optionally, in the above-mentioned clamp beam, the connecting body further includes a central crossbeam and / or a reinforcing crossbeam arranged between the bolster beam and the end crossbeam.

[0022] The clamp-shaped beam provided by this invention has a top plate connected to the upper side of the webs of the two side beams, and a bottom plate connected to the lower side of the webs of the two side beams. This arrangement creates a stable structure for the side beam. Two lug plates are welded to the webs of the two side beams respectively. When the lug plates are under stress, the force is directly transmitted to the webs of the side beams without the need for intermediate components. This results in a shorter force transmission path, reducing the increased risk of breakage due to a longer force transmission path and more connection points, thus improving the safety of the clamp-shaped beam.

[0023] A clamping vehicle, comprising:

[0024] Base frame;

[0025] A clamp-shaped beam is disposed on the base frame, and the clamp-shaped beam is as described in any of the preceding claims.

[0026] Optionally, the clamping cart described above further includes an auxiliary trolley device, which includes:

[0027] Mounting base, fixed on the base frame;

[0028] The trolley telescopic device has one end hinged to the mounting base and the other end is the ground-supporting thrust output end. In use, the ground-supporting thrust output end acts on the force-bearing part.

[0029] Optionally, in the above-mentioned clamping vehicle, the ground-supporting thrust output end is provided with a ground-supporting support, which is hinged to the ground-supporting thrust output end.

[0030] Optionally, in the above-mentioned clamping cart, the auxiliary trolley device further includes an idle support and / or a guardrail, the idle support being fixed to the base frame, and the idle support having a support portion for supporting the trolley telescopic device;

[0031] The guardrail is fixed to the base frame and surrounds the outside of the mounting base.

[0032] The clamping vehicle provided by this invention, having the aforementioned clamp-shaped beam, possesses all the technical effects of the aforementioned clamp-shaped beam, which will not be elaborated upon here. Attached Figure Description

Detailed Implementation

[0041] The core of this invention lies in providing a clamp-shaped beam to optimize the force transmission path of the car ear plate and improve the reliability of the clamp-shaped beam;

[0042] Another core aspect of this invention is to provide a clamping vehicle having the aforementioned clamp-shaped beam.

[0043] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the invention as described in the claims. It should be noted that, for ease of description, only the parts relevant to the invention are shown in the drawings. Unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0044] As shown in Figures 1, 3, and 4, the clamp-shaped beam 300 disclosed in this embodiment of the invention includes two parallel side beams 301 and lug plates 302, which are connected by a connector. The connector links the two side beams 301 into a relatively stable whole, enabling the clamp-shaped beam 300 to stably support the cargo. Each side beam 301 has a lug plate 302 at one end, and the cargo shell also has hinged lug plates corresponding to the lug plates 302 at both ends. When cargo needs to be connected, the hinged lug plates of the cargo are inserted between the two lug plates 302 and fitted with lug pins, thus connecting the cargo to the clamp-shaped beam 300.

[0045] It should be noted that both ends of the cargo are equipped with hinged lugs to connect to the two clamping beams 300 of the clamping vehicle, respectively, loading the cargo between the two clamping beams 300. Simultaneously, two hinged lugs are provided on the left and right sides of the cargo to connect to the lugs 302 of the two side beams 301 of the same clamping beam 300, respectively. In other words, the cargo is connected to the clamping vehicle through four connection points (front, back, left, and right), improving the reliability of cargo securing.

[0046] 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 parallel steel plate structures. The lug plate 302 is also a two steel plate structure and is connected to the two side beam webs 3011 respectively. The thickness of the lug plate 302 is greater than the thickness of the side beam webs 3011, and the end of the lug plate 302 is welded to the side beam webs 3011.

[0047] The clamp-shaped beam 300 disclosed in this embodiment of the invention has a top plate 3016 connected to the upper side of the two side beam webs 3011, and a bottom plate 3012 connected to the lower side of the two side beam webs 3011. This arrangement makes the side beam body 301 form a stable structure. Two lug plates 302 are respectively welded to the two side beam webs 3011. When the lug plate 302 is under force, the force is directly transmitted to the side beam webs 3011 through the lug plate 302 without the need for intermediate parts. The force transmission path is shorter, which reduces the increased risk of breakage caused by a longer force transmission path and more connection points, thus improving the safety of the clamp-shaped beam 300.

[0048] Since the stress-bearing part of the clamp beam 300 is the position of the ear plate 302, in this embodiment, the side beam body 301 can be designed as a trapezoidal structure, that is, the width of the side beam web 3011 near the 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 ear plate 302 has a larger size and ensures sufficient strength.

[0049] 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 wheel 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 wheel ear plate 302 is designed within the insertion port. After the wheel ear plate 302 is welded to the side beam web 3011, the side wall of the insertion port also provides a certain degree of support for the wheel ear plate 302, which can improve the reliability of the connection of the wheel ear plate 302 to a certain extent.

[0050] Furthermore, the end of the side beam bottom plate 3012 is bent to form a bottom plate bending plate, and the side beam end plate 3015 is bent to form an end plate bending plate, forming an insertion opening between the bottom plate bending plate and the end plate bending plate. The bottom plate bending plate can be formed by bending the main body of the side beam bottom plate 3012 downwards, and the end plate bending plate can be formed by bending the main body of the side beam end plate 3015 outwards, so that an insertion opening extending obliquely downwards is formed between the bottom plate bending plate and the end plate bending plate.

[0051] The sides of the ear plate 302 are respectively attached to 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. 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 weld failure and breakage.

[0052] In a specific embodiment of the present invention, the side beam web 3011 has a mating end face formed within the insertion port. Both ends of the mating end face extend to the side beam bottom plate 3012 and the side beam end plate 3015, respectively. The end of the wheel lug 302 is welded to the mating end face. In this embodiment, the insertion port is formed by the side beam bottom plate 3012 and the side beam end plate 3015. The width of the insertion port can be designed according to the width of the wheel lug 302, allowing the wheel lug 302 to be inserted into the insertion port and supported on the side beam bottom plate 3012 and the side beam end plate 3015. To ensure that the wheel lug 302 can be welded to the side beam web 3011 within the insertion port, in this embodiment, the side beam web 3011 has a portion extending into the insertion port, which forms the mating end face to facilitate welding of the wheel lug 302 to the side beam web 3011.

[0053] In this embodiment, the plates of the side beam 301 can be connected by welding to ensure that the side beam 301 forms a stable integral structure. 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 provided at the end of the side beam web 3011 with a larger height to prevent deformation of the side beam web 3011. In addition, multiple side beam reinforcing plates 3013 can also be welded between the two side beam webs 3011.

[0054] As shown in Figure 3, in a specific embodiment of the present invention, the connecting body may include a bolster beam 304 and an end crossbeam 306. The bolster beam 304 is welded to the first end of the two side beams 301, and the end crossbeam 306 is welded to the second end of the two side beams 301. The second end of the side beams 301 is the end where the side beams 301 connect to the wheel lugs 302. The bolster beam 304 and the end crossbeam 306 may extend from the top plate 3016 of the side beams to the bottom plate 3012 of the side beams to ensure a large connection area with the side beams 301 and improve the strength of the clamp beam 300. It should be noted that the height of the bolster beam 304 and the end crossbeam 306 can also be designed according to requirements, and is not limited to the implementation scheme of extending from the top plate 3016 of the side beams to the bottom plate 3012 of the side beams.

[0055] The connector disclosed in this embodiment adopts a scheme in which the pillow beam 304 and the end crossbeam 306 are welded between the two side beams 301. Compared with the traditional tie rod connection, since it is not necessary to use a pin to connect the tie rod to the side beam 301, the problem of too many loose parts in the existing structure and the cumbersome assembly by pin connection is solved, saving time and manpower.

[0056] Furthermore, the connecting body may also include a central crossbeam 305 and / or a reinforcing crossbeam 307 arranged between the bolster beam 304 and the end crossbeam 306. In this embodiment, a number of central crossbeams 305 and / or reinforcing crossbeams 307 may be arranged on the bolster beam 304 and the end crossbeam 306 as needed. The central crossbeam 305 may be an I-beam, and both the central crossbeam 305 and the reinforcing crossbeam 307 may be welded to one side near the top plate 3016 of the side beam.

[0057] As shown in Figure 1, this embodiment of the invention discloses a clamping vehicle, which includes a base frame and a clamping beam 300. The base frame may include a large base frame 200 and a small base frame 400. The clamping beam 300 is disposed on the base frame (which may be the large base frame 200), and the clamping beam 300 is the clamping beam 300 disclosed in the above embodiment. Because it has the above-described clamping beam 300, it possesses all the technical effects of the clamping beam 300 described above, which will not be repeated here.

[0058] When loading and unloading goods, the clamping car needs to be separated into its first and second halves. Because loading and unloading takes a long time, the locomotive cannot wait for extended periods to perform tamping operations on the clamping car. Furthermore, during loading and unloading, the first and second halves need to be repeatedly pushed to adjust the distance between them. Since the first and second halves are quite heavy, a significant amount of manpower is required to move them without a locomotive; alternatively, other tractor vehicles must be rented to tow them, resulting in high loading and unloading costs.

[0059] Based on this, as shown in Figures 5 and 6, the clamping vehicle disclosed in this embodiment of the invention may further include an auxiliary trolley device to save manpower and rental costs of other tractor vehicles, thereby reducing loading and unloading costs. The auxiliary trolley device includes a mounting base 502 and a trolley extension device 501.

[0060] The mounting base 502 is fixed to the base frame (e.g., the main base frame 200), providing a mounting foundation for the trolley telescopic device 501. One end of the trolley telescopic device 501 is hinged to the mounting base 502, and the other end is the ground-supporting thrust output end. In use, the ground-supporting thrust output end acts on the force-bearing part. For example, the ground-supporting thrust output end can be placed against the force-applying position, such as the ground or other fixed parts, serving as the main force-applying component, and is not limited to the ground.

[0061] The trolley telescopic device 501 can be any device capable of changing its length by extending and shortening, including but not limited to hydraulic cylinders, pneumatic cylinders, electric push rods, etc.

[0062] It should be noted that the extension and retraction of the telescopic rod of the trolley telescopic device 501 can be controlled by a remote control to improve operational convenience. The operator can control the extension and retraction of the trolley telescopic device 501 using the buttons on the remote control. After the trolley telescopic device 501 is retracted, the operator only needs to rotate it to the corresponding angle (usually, the operator does not need to assist in rotating the trolley telescopic device 501; when retracting, it will automatically rotate under its own gravity to the angle at which its ground-supporting thrust output end touches the ground. Only when the length of the trolley telescopic device 501 is less than the distance to the ground does the operator need to assist in swinging the trolley telescopic device 501 to ensure it touches the ground at an inclined angle), ensuring that the ground-supporting thrust output end is in contact with the ground. Then, the operator can control the extension of the trolley telescopic device 501 using the buttons on the remote control. Repeating this process will allow the vehicle to be pushed.

[0063] To facilitate the hinge connection between the trolley telescopic device 501 and the mounting base 502, a hinge support 5021 is provided on the mounting base, and a hinge ear plate 5012 is provided at one end of the trolley telescopic device 501. The hinge ear plate 5012 and the hinge support 5021 are hinged together via a hinge shaft. The trolley telescopic device 501 can rotate along the hinge shaft, so that the ground-supporting thrust output end can be supported on the force-bearing part (e.g., the ground) through the rotation of the trolley telescopic device 501. When it is necessary to push the vehicle 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 extension rod of the trolley telescopic device 501 to extend, the overall length of the trolley telescopic device 501 is increased, thereby generating a thrust to push the vehicle to the left, and thus allowing the vehicle to move forward to the left. Similarly, when it is necessary to push the vehicle 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 extension rod of the trolley telescopic device 501 to extend, the overall length of the trolley telescopic device 501 is increased, thereby generating a thrust to push the vehicle to the right, and thus allowing the vehicle to move forward to the right.

[0064] As shown in Figure 5, the auxiliary trolley device disclosed in this embodiment can assist the clamping trolley in moving to the left and right. When the auxiliary clamping trolley moves to the left, the trolley telescopic device 501 rotates to the lower right, and the ground-supporting thrust output end of the trolley telescopic device 501 extends and touches the ground. The telescopic rod of the trolley telescopic device 501 continues to extend, thus pushing the clamping trolley forward a certain distance to the left. After the telescopic rod of the trolley telescopic device 501 retracts to a certain length, the ground-supporting thrust output end touches the ground again, and then the telescopic rod continues to extend, thus pushing the clamping trolley forward again. This process is repeated alternately, so that the clamping trolley continues to move to the left.

[0065] As shown in Figure 6, 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 touches the ground. The telescopic rod of the trolley telescopic device 501 extends further, pushing the clamping trolley forward a certain distance to the right. After the telescopic rod of the trolley telescopic device 501 retracts to a certain length, the ground-supporting thrust output end touches the ground again, and then the telescopic rod extends further, pushing the clamping trolley forward again. This alternating process continues, allowing the clamping trolley to continuously move to the right.

[0066] This invention controls the left and right forward movement of the clamping vehicle using a trolley telescopic device 501, eliminating the need for manual operation or the use of a tractor or other vehicle, thus improving operational convenience and safety. It also saves significant personnel and vehicle rental costs.

[0067] To increase the contact area between the ground and the output end of the ground-supporting thrust, 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 trolley telescopic device 501 can be adjusted according to the angle between the ground and the trolley 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 slippage on the ground during trolley pushing.

[0068] Those skilled in the art will understand that the larger the contact area of ​​the ground support 5011, the greater the friction, and the less likely it is to fail due to slippage when generating a large thrust. Those skilled in the art can select the ground support area of ​​the ground support 5011 according to the application scenario of the auxiliary trolley device and the vehicle used, so as to reduce the footprint of the ground support 5011 while meeting the friction requirements.

[0069] As shown in Figure 5, in order to further improve the grip of the ground support 5011, in this embodiment, the ground support 5011 has a ground support surface, which is the surface that fits against the ground. A gripping part 5013 is provided on this ground support surface. After the ground support surface of the ground support 5011 is supported on the ground, the gripping part 5013 can be inserted into the ground, increasing the friction between the ground support 5011 and the ground, further improving the grip and preventing slippage during operation.

[0070] Furthermore, the gripping part 5013 may include a plurality of insert plates spaced apart on the supporting surface. The insert plates may be installed perpendicular to the supporting surface or inclined to it. The embodiment shown in Figure 5 is that the insert plates are inclined at a certain angle to the supporting surface.

[0071] When the floor insert and the supporting ground are set perpendicularly, and when an auxiliary trolley device is needed to assist in pushing the vehicle, the trolley telescopic device 501 is rotated to a certain angle relative to the ground, and the supporting ground support 5011 is placed on the ground. Then, the gripping part 5013, which is perpendicular to the supporting ground, is inserted into the ground by external force, thereby fixing the telescopic device 501 to the ground. However, this method requires the operator to insert the gripping part 5013 into the ground by external force, which inevitably affects the vehicle's walking efficiency.

[0072] With the floor insert and the supporting ground tilted at a certain angle, the operator does not need to use external force to insert the gripping part 5013 into the ground. Specifically, when the floor insert and the supporting ground are tilted, and when an auxiliary trolley device is needed to assist in pushing the vehicle, the trolley 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 floor insert should be adjusted to tilt in the same direction as the trolley telescopic device 501. For example, if the lower end of the telescopic device 501 is tilted to the right compared to the upper end, then the lower end of the floor insert should also be tilted to the right compared to the upper end. With this setting, when the telescopic rod of the trolley telescopic device 501 extends, making the trolley telescopic device 501 longer, the floor insert can be automatically inserted into the ground without the operator needing to apply external force.

[0073] Because the cylinder and telescopic rod of the trolley telescopic device 501 can rotate relative to each other, one of the hinged ear plate 5012 and the ground support 5011 is mounted on the cylinder, and the other is mounted on the telescopic rod. This allows the distance between the hinged ear plate 5012 and the ground support 5011 to change when the telescopic rod extends or retracts. Furthermore, since the cylinder and telescopic rod can rotate relative to each other, the ground support 5011 can rotate as needed to adjust the tilt direction of the insert plate, ensuring that the insert plate tilts in the same direction as the trolley telescopic device 501.

[0074] The number and spacing of the floorboards can be selected by those skilled in the art based on the application scenario, and are not limited to the method shown in the figure.

[0075] In addition, the gripping part 5013 may also include multiple ground spikes spaced apart on the supporting surface. The ground spikes differ in shape from the floor panels; the floor panels are plate-like structures, while the ground spikes are rod-like structures. It should be noted that both the rod-shaped floor panels and the rod-shaped ground spikes can be inserted into the ground to enhance the grip of the supporting support 5011 and prevent slippage. The ground spikes can also be configured similarly to the floor panels, for example, they can be perpendicular to or inclined to the supporting surface.

[0076] Furthermore, the gripping part 5013 may also include friction patterns spaced apart on the supporting surface. The friction patterns can increase the friction between the supporting support 5011 and the ground, and can also prevent slippage to some extent. Those skilled in the art will understand that the gripping part 5013 may simultaneously have floorboards, spikes, and friction patterns, or may include only one or both of these.

[0077] The thrust generated by the trolley telescopic device 501 is applied to the vehicle to be pushed through the mounting base 502, thereby enabling the vehicle to move. Especially for heavier vehicles, a larger thrust is required. Therefore, the mounting base 502 needs to have sufficient connection strength to prevent it from detaching and breaking due to the large thrust required when the trolley telescopic device 501 assists in pushing the trolley.

[0078] In this embodiment, the mounting base 502 may include a mounting body and an inclined support. The mounting body is fixed to the base frame, and one end of the trolley telescopic device 501 is hinged to the mounting body. Specifically, one end of the trolley telescopic device 501 may be hinged to the lower side of the mounting body, that is, the hinge support 5021 is fixed to the lower side of the mounting body.

[0079] The inclined support is connected to both the mounting base and the vehicle to be pushed. The inclined support can be a triangular plate, with one side welded to the upper surface of the mounting base and the other side welded to the base frame of the clamping vehicle.

[0080] In this embodiment, the mounting base 502 is designed to have an additional 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 (e.g., the welding area, or fasteners can be used for fixation), thus providing greater connection strength and preventing the problem of breakage at the connection.

[0081] The trolley telescopic device 501 is only used when the clamping cart needs to be moved; otherwise, it remains idle. To facilitate the storage of the trolley telescopic device 501 when not in use, in this embodiment, the auxiliary trolley device may further include an idle support. The idle support is fixed to the base frame and has a support portion for supporting the trolley telescopic device 501. The support portion can be an upward-facing slot, through which the trolley telescopic device 501 can be engaged, preventing it from detaching from the idle support and improving the reliability of the idle support in securing the trolley telescopic device 501. It should be noted that the idle support can also secure the trolley telescopic device 501 in other ways, not limited to the slot method.

[0082] When the clamping cart is in normal operation, i.e., when the auxiliary trolley device is not required to assist its movement, the trolley telescopic device 501 can be fixed to an unused support. This prevents the trolley telescopic device 501 from swinging back and forth and colliding with surrounding objects, causing damage to both the surrounding objects and the trolley telescopic device 501 itself, as it is only fixed to the mounting base via a hinge. In this embodiment, using an unused support to fix the trolley telescopic device 501 can restrain its uncontrolled swinging.

[0083] When an auxiliary trolley device is needed to assist in moving the clamping cart, simply remove the trolley telescopic device 501 from the unused support.

[0084] Since the mounting base 502 protrudes beyond the body of the clamping cart, and the mounting base 502 is typically a rectangular plate structure, its edges and corners are relatively sharp, making it easy for operators to bump into it. Therefore, the auxiliary cart device disclosed in this embodiment may also include a protective railing 503. The protective railing 503 is fixed to the base frame and surrounds the outside of the mounting base 502. The protective railing 503 should be formed by bending a relatively rounded rod, or it can be a box structure that surrounds the mounting base 502 inside; in short, it should be able to prevent the sharp parts of the mounting base 502 from colliding with the operator.

[0085] In addition, in order to ensure that the auxiliary trolley device can provide a relatively stable thrust for the clamping cart, auxiliary trolley devices are installed on both sides of the base frame.
