[0024] It needs to be explained that: the top of the hoisting trolley 1 is stably and fixedly connected with the transmission bin 2 through welding, so that displacement or loosening between the two will not occur in complex working environment, limit grooves 3 are symmetrically arranged on the two sides of the transmission bin 2 through precise machining, the limit grooves 3 have strict size tolerance requirements and the width is matched with the connecting rods 6 to limit the connecting rods 6, so that the connecting rods 6 can only move in the limit grooves 3, the gear 4 is rotatably connected with the transmission bin 2 through high-precision bearings, so that the gear 4 can be kept stable and low resistance during operation, the two sides of the gear 4 are respectively and precisely meshed with the toothed plates 5, when the gear 4 rotates, the two toothed plates 5 move in opposite directions, and the connecting rods 6 are fixedly connected with the toothed plates 5 on the sides of the two toothed plates 5 respectively through firm bolt connection. One end of the connecting rod 6 precisely penetrates through the limit groove 3 and is tightly fixed with the toothed plate 5, and the connecting mode ensures that the movement of the toothed plate 5 can be accurately transmitted to the connecting rod 6. The limit blocks 8 are tightly sleeved on the outer walls of the two connecting rods 6, the limit blocks 8 are used for accurately limiting the connecting rods 6 during movement and preventing unnecessary shaking or deviation of the connecting rods 6, and the first fixing rods 9 are fixedly connected with the bottoms of the two connecting rods 6 through welding. The cleaning assemblies are fixedly connected with the bottoms of the two first fixing rods 9, the cleaning assemblies can clean specific working areas during the operation of the hoisting trolley 1, so that the working environment is kept clean, and the self-locking motor 10 is fixedly connected with the transmission bin 2. One end of the output shaft of the self-locking motor 10 penetrates through the surface of the transmission bin 2 and is tightly connected with the gear 4 through key connection, so that the power output by the self-locking motor 10 can be efficiently transmitted to the gear 4 to drive the operation of the whole transmission system, and the self-locking characteristic of the self-locking motor 10 can prevent the gear 4 from rotating, fix the positions of the two toothed plates 5 and prevent the positions from changing.

[0025] In the embodiment of the utility model, the cleaning assembly includes the movable groove 11 arranged at the bottom of the hoisting trolley 1, the first rotating shaft 12 is arranged in the movable groove 11, the first rotating shaft 12 is fixedly connected with the driving bevel gear 13 at one end, and the other end is fixedly connected with the rotating wheel of the hoisting trolley 1, the driving bevel gear 13 is meshed with the driven bevel gear 14, the driven bevel gear 14 is fixedly connected with the second rotating shaft 15 at the bottom, the second rotating shaft 15 is sleeved with the limiting rod 21 on the outer wall, one end of the limiting rod 21 is fixedly connected with the inner wall of the movable groove 11, the second rotating shaft 15 is provided with the containing plate 16 below, the containing plate 16 is rotatably connected with the scraper 17 at the bottom, the containing plate 16 is fixedly connected with the guide plate 18 at the bottom on the side away from the first fixing rod 9, the guide plate 18 is a triangular structure, and the plurality of containing plates 16 are fixedly connected with the bottoms of the two first fixing rods 9 on the two sides respectively.

[0026] It should be noted that: the size, depth and width of the movable groove 11 are accurately planned according to the specifications and operation requirements of other components of the cleaning assembly, so as to provide a stable and suitable installation and operation space for the subsequent components. The other end of the first rotating shaft 12 is fixedly connected with the rotating wheel of the hoisting trolley 1. When the rotating wheel of the hoisting trolley 1 rotates, it will directly drive the first rotating shaft 12 to rotate synchronously, thereby providing a power source for the entire cleaning assembly. This ingenious design enables the cleaning assembly to be synchronized with the operation of the hoisting trolley 1 without the need for additional power devices. The driving bevel gear 13 and the driven bevel gear 14 are precisely meshed and connected, ensuring accurate transmission ratio and stable power transmission from the first rotating shaft 12 to the driven bevel gear 14. The bottom of the driven bevel gear 14 is also fixedly connected with the second rotating shaft 15. In order to ensure the stability and accuracy of the second rotating shaft 15 during rotation, a limiting rod 21 is sleeved on the outer wall of the second rotating shaft 15. One end of the limiting rod 21 is fixedly connected with the inner wall of the movable groove 11 by bolts. It can effectively limit the radial shaking and axial displacement of the second rotating shaft 15, ensuring that the second rotating shaft 15 always remains in the correct rotating position, thereby ensuring the normal operation of the entire cleaning assembly. The lower end of the second rotating shaft 15 penetrates the surface of the containing plate 16 and is fixedly connected with the scraper 17. The containing plate 16 is fixedly connected with the two first fixed rods 9 on both sides of the bottom. The containing plate 16 is made of high-strength aluminum alloy material. Its main function is to fix the position of the scraper 17 and the guide plate 18. When the second rotating shaft 15 rotates, it can drive the scraper 17 to rotate on the containing plate 16. The scraper 17 is made of rubber, which can effectively remove dust, stones and other debris. The guide plate 18 is designed in a unique triangular structure, which has a good guiding effect. When the scraper 17 scrapes the debris, the guide plate 18 can guide and collect the debris, avoiding scattering of the debris, improving the cleaning efficiency and effect.

[0027] In the embodiment of the utility model, the hoisting trolley 1 is movably connected with the movable block 19 at the bottom, and the second fixed rod 20 is fixedly connected with the lower surface of the movable block 19, and the collecting bin 7 is fixedly connected with the bottom of the second fixed rod 20.

[0028] It should be noted that: the movable block 19 is T-shaped and can be slid into the T-shaped groove formed in the bottom of the hoisting trolley 1, so as to realize the connection or separation of the movable block 19 and the hoisting trolley 1. The second fixed rod 20 is designed in a hollow tubular shape, which not only has sufficient strength but also effectively reduces its own weight and the overall burden of the hoisting trolley 1. The collecting bin 7 is fixedly connected with the bottom of the second fixed rod 20 by bolts and nuts. The collecting bin 7 is designed in a cuboid shape, which is convenient to install and fix and has a large storage space. The guide plate 18 can guide the debris into the collecting bin 7 for collection.

[0029] The working principle of the lifting trolley of the double-beam portal crane is as follows: when the lifting trolley 1 moves, the self-locking motor 10 is started, the gear 4 is driven to rotate, the one side tooth plate 5 is driven to move upward, the one side connecting rod 6 is driven to move upward, the first fixed rod 9 is pulled to move upward, the first fixed rod 9 pulls the two sides of the containing plate 16, the containing plate 16 drives the scraper 17 to move upward along the movable groove 11, the scraper 17 drives the second rotating shaft 15 to drive the driven bevel gear 14 to separate from the driving bevel gear 13, the driving bevel gear 13 is prevented from driving the driven bevel gear 14 to rotate, the two sides of the cleaning device are driven to move upward, the other side tooth plate 5 moves downward, the other side 6 connecting rod moves downward to drive the first fixed rod 9, the containing plate 16 is pushed to move downward, the driven bevel gear 14 is engaged with the driving bevel gear 13, the two cleaning devices on the other side move downward and abut against the end faces of the two main beams, and the sundries on the advancing path are cleaned.

[0030] When the lifting trolley 1 moves, the rotating wheel of the lifting trolley 1 rotates to drive the first rotating shaft 12, so that the driving bevel gear 13 is driven to rotate, the driven bevel gear 14 is driven to rotate, and the scraper 17 is driven to rotate, so that the end face of the main beam can be cleaned, at this time, the sundries are moved to the collecting bin 7 through the inclined surface of the guide plate 18, and the collecting bin 7 and the movable block 19 can be cleaned by pulling the second fixed rod 20 to slide out along the T-shaped groove opened at the bottom of the lifting trolley 1.
