The upper beam connecting plate is provided between the two upper beam bodies 11 for connection, and a connecting rod 17 is also provided to connect and tighten the two upper beam bodies 11. In this arrangement structure, the top wheel axle 13 of the car is precisely matched with the circular hole of the upper beam, and the axle length is larger than the spacing space inside the upper beam. Therefore, when replacing the top wheel 12 of the car, the top wheel 12 cannot be directly removed. It is necessary to first remove the side rope, lower rope, upper beam connecting plate, upper cover 18, lower cover 19 installed on the upper beam body, and remove one side of the upper beam body 11 before removing the top wheel 12 of the car. It is extremely inconvenient to replace the top wheel 12 of the car. If the upper beam body 11 is removed, the car frame will lose support, and there is a risk of the car tilting or falling apart.

[0019] The specific implementation of the present utility model will be further described below in conjunction with the accompanying drawings.

[0020] like Figure 2~Figure 6 As shown, the utility model is an easily disassembled upper beam assembly for a car top wheel, which comprises two upper beams 21 arranged side by side in parallel, an upper beam connecting plate 26 fixedly connected to the upper beams 21 to keep them parallel, a car top wheel 22 whose axis is perpendicular to the upper beams 21 and located between the two upper beams 21, and a clamping plate 25 detachably fixedly installed on the inner side of the upper beams 21, wherein the clamping plate 25 has a support hole for the end of the axle 23 of the car top wheel 22 to fit through and located above the upper beams 21. The clamping plate 25 detachably fixedly installed on the upper beams 21 is arranged between the two upper beams 21 and close to the upper beams 21 as a supporting connection component, and a support hole for the axle 23 of the car top wheel to pass through is arranged on the clamping plate 25, so that the car top wheel 22 can be installed using the clamping plate 25. The car top wheel 22 can be disassembled by disassembling the clamping plate 25, without disassembling the upper beam body, thereby facilitating the disassembly and replacement of the car top wheel 22. The two ends of the upper beam connecting plate 26 are fixedly connected to the upper beam 21 so that a stable connection structure is formed between the upper beams 21, and the process of disassembling and assembling the car top wheel 22 does not affect the stability of the upper beam main structure.

[0021] The two ends of the upper beam connecting plate 26 are fixedly connected to the upper side surfaces of the upper beams 21. This not only limits the spacing between the upper beams 21, but also adjusts the level of the upper beams 21.

[0022] Preferably, at least two of the upper beam connecting plates 26 are angle steels extending across the two upper beams. A connecting plate is provided on the upper side of the upper beam, so that an angle steel that integrally spans the two upper beams 21 can be provided as the upper beam connecting plate, thereby preventing the upper beam connecting plate 26 from bending, thereby making the structure stronger, preventing the upper beam 21 from axial torsion, and making the structure more stable.

[0023] More preferably, the lower edge of the clamping plate 25 is lower than the lower edge of the car top wheel 22, and a tension bolt 27 passing through the clamping plate 25 on both sides and the upper beam 21 is provided below the car top wheel 22. An upper beam connecting plate 26 is provided on the upper side of the upper beam 21 at the front and rear sides of the car top wheel 22, and the upper beam is supported and pulled and fixed with the tension bolts 27 in three directions, thereby improving the stability of the overall structure.

[0024] The supporting hole is a circular hole adapted to the end of a circular wheel shaft, which is convenient for installing the car top wheel 22.

[0025] More preferably, the positions where the two ends of the axle 23 of the car top wheel 22 pass through the axle clamping plate 25 are provided with side grooves perpendicular to the axis center, and an axle clamping plate 35 fixedly locked to the axle clamping plate 25 is provided close to the outer side surface of the axle clamping plate 25, and one side of the axle clamping plate 35 is adapted to be embedded in the side groove to prevent the axle 23 from rotating and also to prevent the axle 23 from retreating, thereby ensuring the stability of the installation of the car top wheel 22.

[0026] The shaft clamping plate 25 is fixedly mounted on the upper beam 21 by fastening bolts. The fastening bolts can be removed to disassemble the shaft clamping plate 25 and the car top wheel 22. The car top wheel 22 can be removed by disassembling the shaft clamping plate 25 on one side.

[0027] Among them, the upper side of the upper beam 21 is provided with an upper cover 28 that can cover the upper sides of the two car top wheels 22. The upper cover 28 is tightly connected to the upper end of the clamping plate 25, so that the installation position of the upper cover is higher and does not need to extend down to the upper beam, thereby simplifying the structure of the upper cover and reducing its height to save materials and reduce costs, and it is easier to install, and it can also avoid the installation position of the upper beam, so that the upper beam connecting plate 26 can be set on the upper side of the upper beam, with better push-pull strength and better structural stability. The upper beam connecting plate 26 in the prior art is located on the inner side between the two upper beams 21, and the end of the upper beam connecting plate 26 is bent and then tightly connected to the upper beam, and its connection strength is lacking.

[0028] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
