Description

Technical Field

[0001] The utility model relates to the technical field of flat car accessories, in particular to a novel portable ferry for railway flat cars. Background Art

[0002] Flat cars are mainly used to transport large or heavy goods such as steel, wood, cars, and mechanical equipment. Flat cars can also meet the needs of national defense and carry various military equipment. Among them, flat cars without end plates (fixed end plates of flat cars are lost or damaged) need to use portable crossing plates at the ends to fill the gaps between flat cars, so as to facilitate the equipment to move from flat cars to the ground, or from the ground to flat cars. However, a railway flat car ferry plate published in China with utility model patent application number 201120434627X requires a torque wrench to be used to tighten the connection between it and the flat car end during use, specifically, the fastening bolts are used to position the end plate, the end plate bracket, and the bolts to clamp and fix the end plate. However, using this method, the first support beam needs to be inserted, and then the three parties need to cooperate to perform the tightening operation. Therefore, during the tightening process, the entire ferry plate is prone to uneven force, and abnormalities such as tilting or warping occur. Therefore, another person is needed to cooperate to facilitate the tightening operation, which results in time-consuming and labor-intensive assembly or disassembly, and low work efficiency. Utility Model Content

[0003] In view of the problem that the existing railway flat car ferry is time-consuming and labor-intensive to assemble or disassemble, resulting in low work efficiency, the utility model provides a novel portable railway flat car ferry, which is easy to install and operate on the end of the flat car, saves time and labor, and improves work efficiency.

[0004] The technical solution is as follows: a novel portable railroad flat car ferry, comprising a first support beam and a second support beam, wherein the first support beam and the second support beam are connected by a first reinforcing rib, and the first support beam and the second support beam are externally connected to a first telescopic rod sleeve structure, characterized in that: a second telescopic rod sleeve structure is provided at a side of the second support beam away from an end connected to the first support beam, a rectangular positioning tube is provided on the outside of the second telescopic rod sleeve structure, a rectangular positioning hole is provided on the rectangular positioning tube, and the rectangular positioning tube is connected and fixed to an end bracket at an end of the flat car by using a combination of bolts and nuts;

[0005] It is further characterized in that: the rectangular positioning tubes include two and are vertically arranged, and are respectively fixedly connected to the two side walls of the second telescopic rod sleeve structure;

[0006] The first telescopic rod sleeve structure and the second telescopic rod sleeve structure respectively include an external rectangular sleeve outer tube, a rectangular inner tube with a sliding fit connection is provided inside the sleeve outer tube, a positioning hole is provided at the end of the sleeve outer tube, and evenly spaced connecting holes are provided on the rectangular inner tube, and the positioning hole is connected to the connecting hole by a positioning pin.

[0007] After adopting the above structure, since the side of the second support beam is provided with a second telescopic rod sleeve structure, it can cooperate with the first telescopic rod sleeve structure to provide a larger auxiliary plane area. At the same time, a rectangular positioning tube is provided on the outside of the second telescopic rod sleeve structure. By inserting the rectangular positioning tube into the end bracket at the end of the flat car and fixing it with the positioning parts of bolts and nuts, the assembly is convenient, time and labor are saved, and work efficiency is improved.

[0009] Figure 2 It is a schematic diagram of the overall structure of the utility model in another direction;

[0010] Figure 3 It is a schematic diagram of the structure of the utility model installed on the upper end of a flat car. DETAILED DESCRIPTION

[0011] like Figure 1 , 2 As shown, a new type of portable ferry for railway flat cars includes a first support beam 1 and a second support beam 2. The first support beam 1 and the second support beam 2 are connected by a first reinforcing rib 3. The first support beam 1 and the second support beam 2 are externally connected with a first telescopic rod sleeve structure 4. The side of the second support beam 2 away from the end connected to the first support beam 1 is provided with a second telescopic rod sleeve structure 5. A second reinforcing rib 9 is provided between the first telescopic rod sleeve structure 4 and the second telescopic rod sleeve structure 5. By respectively setting two mutually parallel first telescopic rod sleeve structures 4 and second telescopic rod sleeve structures 5, a larger plane area can be provided when the equipment or goods on the auxiliary flat car are moved. Specifically, the first telescopic rod sleeve structure 4 and the second telescopic rod sleeve structure 5 have the same structure, both of which include an external rectangular sleeve outer tube 6, a rectangular inner tube 7 connected by sliding fit is provided inside the sleeve outer tube 6, a positioning hole 61 is provided at the end of the sleeve outer tube 6, and the rectangular inner tube 7 is provided with evenly spaced connection holes 71. The rectangular inner tube 7 is pulled outward, and the positioning hole 61 is connected to the connecting hole 71 by a positioning pin (not shown in the figure), so that the extended position of the rectangular inner tube 71 is fixed.

[0012] A rectangular positioning tube 8 is provided on the sleeve outer tube of the second telescopic rod sleeve structure 5. The rectangular positioning tube 8 includes two and is vertically arranged. The rectangular positioning tubes 8 are respectively fixedly connected to the two side walls of the sleeve outer tube of the second telescopic rod sleeve structure 5. A rectangular positioning hole 81 is provided on the rectangular positioning tube 8. The rectangular positioning tube 8 is connected and fixed to the end bracket 10 at the end of the flat car by using a combination of bolts and nuts. By connecting the rectangular positioning tubes 8 at different positions to the end bracket of the flat car, the ferry of the utility model can be set parallel or vertically to the body surface of the flat car to achieve different usage purposes. When set parallel to the body of the flat car, such as Figure 3 As shown, two ferry plates are arranged at the end of the flat car, and two installation states of the two ferry plates are shown in the figure. When the area of ​​the flat car needs to be increased, the ferry plates of the utility model are arranged in parallel, and the bracket 9 at the end of the flat car contacts the bottom of the ferry plate and plays a supporting role. By adjusting the length of the first telescopic rod sleeve structure 4 and the second telescopic rod sleeve structure 5 thereon, the auxiliary support area of ​​the ferry plate is increased. At the same time, the ferry plate is directly connected to the end of the flat car by a rectangular positioning tube 8 using a bolt and nut assembly, so it is not easy to rotate or shake, has good connection stability, and is easy to operate, saving time and effort. When it is not needed, the ferry plate is arranged vertically. At this time, the ferry plate is directly connected to the end of the flat car by a bolt and nut assembly through another rectangular positioning tube 8. At this time, the ferry plate is equivalent to the end plate.

[0013] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by anyone familiar with the technology within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
