Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0025] Please also refer to Figures 1 to 4 The auxiliary device for paving railway boxcar floors provided by the present invention is now described. The auxiliary device for paving railway boxcar floors comprises a transfer platform 1 located outside a carriage 10 and a movable trolley 2 located inside the carriage 10. The transfer platform 1 has a load-bearing plate 11 for receiving and moving steel plates, and the movable trolley 2 has a support plate 21 for receiving and moving the steel plates within the carriage 10. The load-bearing plate 11 can be moved upward to be flush with the support plate 21, thereby allowing the steel plates to be transferred horizontally onto the support plate 21.

[0026] Compared with the prior art, the auxiliary device for paving railway boxcar floors provided in this embodiment utilizes the transfer platform 1 outside the carriage 10 to receive the steel plates transported by the lifting equipment, and drives the steel plates to dock with the support plates 21 of the mobile trolley 2 in the carriage 10 by lifting and moving the load-bearing plate 11 on the transfer platform 1, so as to facilitate pushing the steel plates onto the support plates 21, and then the mobile trolley 2 drives the steel plates to move to the position where they need to be paved in the carriage 10. In the above process, the joint operation of the transfer platform 1 and the mobile trolley 2 inside and outside the carriage 10 meets the steel plate transportation needs of the steel floor paving operation in the boxcar, and the operation is simple and convenient, which greatly reduces the labor intensity of manual operation and improves work efficiency. At the same time, the lifting and lowering setting of the load-bearing plate 11 enables the transfer platform 1 to dock with the mobile trolley 2 in carriages 10 of different heights, thereby improving the scope of use and practicality of the device.

[0027] It should be noted that the steel floor of the boxcar compartment 10 is made of multiple single steel plates welded together. For compartments 10 that need to have their floors replaced, the mobile trolley 2 can be placed directly on the original floor to transport the new floor. For compartments 10 that need to have new floors installed, the steel plates on the transfer platform 1 can be manually pushed into the compartment 10, and after the steel plates are laid in the middle of the compartment 10, the mobile trolley 2 can be placed on the steel plates to receive and transport the subsequent steel plates. Specifically, the length of a single floor matches the width of the compartment 10, and the mobile trolley 2 pushes the steel plates along the length direction of the compartment 10. A "wave-catching" paving method is used in the compartment 10, that is, the steel plates are moved from the middle of the compartment 10 to the two ends of the compartment 10 for progressive paving, and the cycle is repeated until the steel floor is laid.

[0028] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 2 A plurality of transmission rollers 12 are rotatably connected to the carrying plate 11 and are arranged with their main shafts perpendicular to the conveying direction of the steel plate. The plurality of transmission rollers 12 are arranged at intervals along the conveying direction of the steel plate.

[0029] In this embodiment, the lifting equipment transports the steel plate to the transfer platform 1. The load plate 11 is raised and lowered according to the height of the carriage 10 to ensure that the load plate 11 is flush with the support plate 21 of the mobile trolley 2 in the carriage 10. At this point, the steel plate needs to be manually pushed onto the support plate 21. Multiple transmission rollers 12 are provided on the load plate 11. During the process of pushing the steel plate, the transmission rollers 12 roll accordingly, converting sliding friction into rolling friction. This greatly reduces the frictional resistance when pushing the steel plate and reduces the operator's operating intensity.

[0030] Furthermore, the transmission roller 12 may be made of a rubber roller, or a structure in which a rubber sleeve is wrapped around the periphery of a steel roller to protect the steel plate from being scratched.

[0031] In some embodiments, the transmission roller 12 can also be changed to a universal steel ball wheel structure to form point contact between the steel plate and the supporting plate 11. The flexible rolling characteristics of the universal steel ball wheel itself can be used to enable the steel plate to slide flexibly, thereby achieving horizontal transfer of the steel plate.

[0032] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 2 The transfer platform 1 includes a frame 13 and a lifting mechanism 14 connected to the top of the frame 13 , and the carrying plate 11 is connected to the top of the lifting mechanism 14 .

[0033] In this embodiment, the frame 13 can be made of a plurality of rectangular steel pipes and a top plate welded together to ensure the strength of the frame 13. The height of the frame 13 can reach more than half the height of the floor of the lowest adapted compartment 10. On the one hand, the appropriate height facilitates operation by workers, and on the other hand, the load plate 11 can be fine-tuned by the lifting mechanism 14 to dock with the support plate 21, which helps to improve the stability of the transfer platform 1.

[0034] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 2 The lifting mechanism 14 includes two groups of scissors support assemblies 141 and a telescopic driving member 142 for driving the scissors support assemblies 141 to rise and fall. The two groups of scissors support assemblies 141 are respectively arranged near the two sides of the supporting plate 11. A linkage rod 143 is connected between the two groups of scissors support assemblies 141. The lower end of the telescopic driving member 142 is hinged to the frame 13, and the upper end of the telescopic driving member 142 is hinged to the linkage rod 143.

[0035] In this embodiment, each set of scissor support assemblies 141 includes a first scissor arm and a second scissor arm hinged to each other. The lower end of the first scissor arm is slidably connected to the frame 13, and the upper end is hinged to the bottom of the supporting plate 11. The lower end of the second scissor arm is hinged to the frame 13, and the upper end is slidably connected to the bottom of the supporting plate 11. The two sets of scissor support assemblies 141 are respectively arranged close to both sides of the supporting plate 11 to ensure the smooth lifting and lowering of the supporting plate 11. The linkage rod 143 is connected between the two opposite first scissor arms or the second scissor arms. The extension and retraction of the telescopic drive member 142 can push the linkage rod 143 to swing vertically, thereby driving the second scissor arm and the first scissor arm to swing vertically around their respective hinge points to achieve the lifting and lowering of the supporting plate 11.

[0036] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 2 The telescopic driving member 142 is an electric cylinder, and the frame 13 is provided with a battery 15 electrically connected to the telescopic driving member 142 and a control switch 16 electrically connected to the battery 15.

[0037] In this embodiment, a battery 15 is installed on the frame 13 to provide power to the telescopic drive 142, eliminating the need for external power supply cables, thereby preventing interference with the steel plate transportation process. The telescopic drive 142 is activated and deactivated by a control switch 16, ensuring the reliability of the lifting mechanism 14.

[0038] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 2The bottom of the frame 13 is connected to four first running wheels 17, and the first running wheels 17 are respectively arranged near the four corners of the frame 13. The bottom of the frame 13 is also connected to four support members 18 which are arranged one by one corresponding to the first running wheels 17. The support member 18 has a support part 181 that can extend downward to support on the ground.

[0039] In this embodiment, to facilitate the movement of the transfer platform 1, first running wheels 17 are provided at the bottom of the frame 13, and a handle 131 is provided on one side of the frame 13 to facilitate pushing the frame 13 to move the transfer platform 1. Specifically, the two first running wheels 17 near the handle 131 are universal wheels, while the two first running wheels 17 away from the handle 131 are fixed wheels, facilitating the movement of the frame 13. A control switch 16 is provided on the handle 131 to facilitate operator operation.

[0040] After the transfer platform 1 is moved to the door of the carriage 10, in order to prevent the frame 13 from slipping during the transportation of the steel plates, a support member 18 is provided at the bottom of the frame 13 to replace the first running wheel 17 to support the frame 13. Specifically, four support members 18 are also provided, which correspond to the four first running wheels 17 one by one to ensure the stability of the frame 13. When the transfer platform 1 is in the walking state, the support portion 181 is separated from the ground to avoid hindering the movement of the first running wheel 17; when the transfer platform 1 is moved to a suitable position, the support portion 181 extends downward until it contacts the ground, and then continues to extend downward a certain distance to lift the first running wheel 17 to separate it from the ground. At this time, the four support portions 181 can ensure stable support for the frame 13.

[0041] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 2 and Figure 3 The support member 18 includes a support base 182 connected to the frame 13 and an adjusting screw 183 threadedly connected to the side of the support base 182. The adjusting screw 183 extends in the up and down directions. The support portion 181 is a chassis connected to the lower end of the adjusting screw 183. The upper end of the adjusting screw 183 is connected to a rotating handle 184 extending radially outward.

[0042] In this embodiment, the support base 182 can be welded to the frame 13. A threaded hole extending vertically through one side of the support base 182 is formed, into which the adjustment screw 183 is threadedly connected. The rotary handle 184 includes a handle rod extending radially through the adjustment screw 183 and a handle ball disposed at the end of the handle rod. The chassis and the adjustment screw 183 are detachably connected, for example, by being threadedly connected to the chassis and the adjustment screw 183 or by fasteners such as screws. Horizontally turning the rotary handle 184 causes the adjustment screw 183 to rotate and extend downward relative to the support base 182, thereby supporting the chassis on the ground.

[0043] Specifically, the frame 13 is a frame-shaped structure formed by welding rectangular tubes. The adjusting screw 183 is located on the side of the support seat 182 close to the middle of the frame 13. The frame-shaped structure of the frame 13 can provide an operating space for the rotation of the handle 184. This arrangement avoids the support member 18 protruding outward from the outside of the frame 13, thereby avoiding affecting the workers' operation of pushing the steel plate from both sides of the frame 13.

[0044] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 4 The mobile trolley 2 includes a body 22 , a handrail 221 connected to one side of the body 22 , and a second traveling wheel 23 connected to the bottom of the body 22 , and the support plate 21 is connected to the top of the body 22 .

[0045] In this embodiment, the height of the vehicle body 22 is relatively low to lower the center of gravity of the steel plates during transportation, ensuring smooth transportation. Furthermore, the vehicle body 22 is constructed of aluminum alloy, which effectively reduces its weight, allowing it to be easily carried by a single person. Once loaded with steel plates, it is flexible and easy to move. Four second running wheels 23 are also provided, positioned near the four corners of the vehicle body 22. The two second running wheels 23 near the handrail 221 are universal wheels, while the two second running wheels 23 away from the handrail 221 are fixed wheels, facilitating the movement of the mobile cart 2.

[0046] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 4 A plurality of spaced-apart universal balls 24 are connected in a rolling manner to the top surface of the support plate 21 , and the universal balls 24 are used to support and guide the steel plate.

[0047] In this embodiment, a number of universal balls 24 can be arranged in a rectangular array on the top surface of the support plate 21. The arrangement of the universal balls 24 changes the surface contact between the steel plate and the support plate 21 into multiple point contacts, thereby reducing the friction coefficient between the steel plate and the support plate 21, so that the steel plate can be easily pushed onto the support plate 21 or easily pushed out from the support plate 21, while also reducing the wear of the support plate 21 on the steel plate.

[0048] As a specific embodiment of the auxiliary device for paving railway boxcar floors provided by the utility model, see Figure 4 A flexible chain 25 is connected to the handrail 221, and the outward end of the flexible chain 25 is connected to a chain hook 26 for hooking on the side edge of the steel plate.

[0049] In this embodiment, the flexible chain 25 is a circular chain formed by linking multiple circular links. One end of the flexible chain 25 is connected to the handrail 221, and the other end is connected to a chain hook 26. When the mobile cart 2 is transporting steel plates, the chain hook 26 can be hooked onto the outer edge of the steel plate to secure it and prevent it from slipping. When the mobile cart 2 is not in use, the flexible chain 25 can be wrapped around the handrail 221 for easy storage and to prevent it from becoming disorganized.

[0050] Furthermore, the chain hooks 26 can be connected to the flexible chain 25 at different locations depending on the width of the steel plate, ensuring that the flexible chain 25 can stably hook individual steel plates of varying widths. Two sets of flexible chains 25 and chain hooks 26 are provided, one on each side of the handrail 221. Using these two sets of chain hooks 26 to hook the steel plate increases its stability.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
