[0002] In the field of building construction, as an important safety protection device, the climbing frame net is widely used on the outer layer of the scaffolding to prevent people and objects from falling. However, at present, when transporting the climbing frame net at the construction site, it mainly relies on manual handling or small cart transportation. These methods have problems such as low efficiency and cumbersome operation.

[0003] The small cart transportation plan often requires binding and fixing the climbing frame net. And due to size limitations, only a small amount of climbing frame nets can be transported each time, resulting in low transportation efficiency. At the same time, it increases the labor intensity of construction workers. The existing transportation methods cannot meet the needs of the construction site for efficient and convenient transportation of climbing frame nets. There is an urgent need for a new type of transportation tool that can solve the above problems.

[0032] Please refer to Figure 1-2 , in the climbing frame net transport vehicle of this embodiment, it includes a vehicle frame 1. The vehicle frame 1 is U-shaped. Grips 7 are fixed on the upper surfaces of the left and right sides of the vehicle frame 1 to facilitate pushing the vehicle frame 1 to move. Connecting rods 5 are fixed on both the front and rear sides of the vehicle frame 1 to increase the stability of the vehicle frame 1. Wheels 6 are rotatably connected to both the left and right sides of the vehicle frame 1 through bearing seats to facilitate pushing the vehicle frame 1 to move. A plurality of boxes 3 are provided on the lower surface of the inner cavity of the vehicle frame 1. An installation mechanism 2 for limiting the boxes 3 is provided inside the vehicle frame 1.

The climbing frame net is fixed through the fixing mechanism 4, which facilitates the vehicle frame 1 to drive the climbing frame net to move.

[0033] Please refer to Figure 3 , in order to facilitate fixing the climbing frame net, the fixing mechanism 4 in this embodiment includes a rotating component and a limiting component. The rotating component includes a first rotating rod 401 rotatably connected to the lower surface of the inner cavity of the box 3 through a bearing seat, a worm 402 fixed on the upper surface of the first rotating rod 401, a second rotating rod 403 fixed on the upper surface of the worm 402 and penetrating and extending above the box 3, a threaded rod 404 rotatably connected between the front and rear sides of the inner cavity of the box 3 through a bearing seat, and a worm gear 405 fixed on the outer surface of the threaded rod 404 and meshing with the worm 402. The second rotating rod 403 drives the worm 402 and the first rotating rod 401 to rotate together, and the worm 402 drives the worm gear 405 and the threaded rod 404 to rotate together.

[0034] The limiting component includes two moving blocks 406 threadedly connected to the outer surface of the threaded rod 404, clamping blocks 407 fixed on the upper surfaces of the moving blocks 406, and two vertical plates 408 fixed on the inner cavity wall of the box 3. When the threaded rod 404 rotates, the two moving blocks 406 move relatively or away from each other simultaneously, and drive the clamping blocks 407 to move together.

[0035] Among them, the thread of the threaded rod 404 is in two sections, and the two thread directions are opposite. When the threaded rod 404 rotates, the two moving blocks 406 move relatively or away from each other simultaneously. A rotating handle is fixed on the upper surface of the second rotating rod 403 to facilitate driving the second rotating rod 403 to rotate.

[0036] In addition, a rotating hole is formed on the front surface of the vertical plate 408, and the threaded rod 404 is rotatably connected to the inside of the rotating hole through a bearing to increase the stability when the threaded rod 404 rotates. Two sliding rods are fixed between the two vertical plates 408, and the moving blocks 406 are slidably connected to the outer surfaces of the sliding rods to increase the stability when the moving blocks 406 move.

[0037] In the fixing mechanism 4 of this embodiment, the climbing frame net is placed between two clamping blocks 407. The rotating handle is rotated to drive the second rotating rod 403, the worm 402 and the first rotating rod 401 to rotate together. The worm 402 drives the worm wheel 405 and the threaded rod 404 to rotate together, so that the two moving blocks 406 move relatively at the same time. The moving block 406 drives the clamping block 407 to move together, and the climbing frame net is clamped and fixed by the clamping block 407, which facilitates the transportation of the climbing frame net by a transport vehicle and prevents the climbing frame net from loosening and falling during transportation.

[0038] Please refer to Figure 4-5 , in order to facilitate the disassembly and packing of the box body 3, the installation mechanism 2 in this embodiment includes an insertion block 208 fixed to the lower surface of the box body 3. A plurality of cavities 201 are opened inside the vehicle frame 1, and a plurality of slots 209 are opened on the lower surface of the inner cavity of the vehicle frame 1. A card hole 207 is opened on the right side of the insertion block 208. The installation mechanism 2 further includes a telescopic rod 202 fixed to the right side of the inner cavity of the cavity 201, a spring 203 sleeved on the outer surface of the telescopic rod 202, a moving block 204 fixed to the left side of the telescopic rod 202, a pull rod 205 fixed to the front of the moving block 204, and a clamping rod 206 fixed to the left side of the moving block 204. The moving block 204 and the clamping rod 206 are driven to move together by the pull rod 205.

[0039] Among them, the insertion block 208 is slidably connected to the inside of the slot 209 for limiting the box body 3, and the clamping rod 206 is slidably connected to the inside of the card hole 207 for fixing the box body 3.

[0040] In addition, the left side of the spring 203 is fixed to the right side of the moving block 204, and the right side of the spring 203 is fixed to the right side of the inner cavity of the cavity 201. The spring 203 is used to reset the moving block 204, driving the clamping rod 206 to snap into the inside of the card hole 207 to install and fix the box body 3.

[0041] Furthermore, a plurality of square holes are opened on the front of the vehicle frame 1, and the pull rod 205 is slidably connected to the inside of the square holes, which facilitates the movement of the moving block 204 driven by the pull rod 205.

[0042] It should be noted that the telescopic rod 202 includes a rod sleeve fixed to the right side of the inner cavity of the cavity 201, a sleeve rod slidably connected to the inside of the rod sleeve, a limit block fixed to the back of the sleeve rod, a limit groove opened on the back of the inner cavity of the rod sleeve, the limit block is slidably connected to the inside of the limit groove, and the left side of the sleeve rod is fixed to the right side of the moving block 204. The telescopic rod 202 enables the moving block 204 to perform a linear motion left and right.

[0043] In the installation mechanism 2 of this embodiment, pulling the pull rod 205 drives the movable block 204 and the clamping rod 206 to move together and compress the spring 203, causing the clamping rod 206 to move away from the slot 209. Insert the insertion block 208 into the inside of the slot 209, release the pull rod 205, and the movable block 204 resets, causing the clamping rod 206 to snap into the inside of the clamping hole 207, installing the insertion block 208 and the box body 3. Conversely, the box body 3 can be disassembled, and the operation is simple.

[0044] The working principle of the above embodiment is as follows:

[0045] (1) Place the climbing frame net between the two clamping blocks 407, rotate the rotating handle, the rotating handle drives the second rotating rod 403 to rotate, drive the worm 402 and the first rotating rod 401 to rotate together through the second rotating rod 403, drive the worm gear 405 and the threaded rod 404 to rotate together through the worm 402. Since the thread directions of the two sections of the threaded rod 404 are opposite, drive the two moving blocks 406 to move relatively at the same time by rotating the threaded rod 404. The moving blocks 406 will slide on the outer surface of the sliding rod, increasing the stability when the moving blocks 406 move. When the moving blocks 406 move, they will drive the clamping blocks 407 to move together, and clamp and fix the climbing frame net through the clamping blocks 407, facilitating the transportation of the climbing frame net by the transport vehicle and preventing the climbing frame net from loosening and falling during transportation.

[0046] (2) When the box body 3 needs to be installed, pull the pull rod 205. The pull rod 205 drives the movable block 204 to move in the cavity 201 and compress the spring 203 and the telescopic rod 202. The movable block 204 will drive the clamping rod 206 to move together at the same time, causing the clamping rod 206 to move away from the slot 209. At this time, insert the insertion block 208 into the inside of the slot 209, release the pull rod 205, and the movable block 204 will reset under the action of the spring 203, driving the clamping rod 206 to move, causing the clamping rod 206 to snap into the inside of the clamping hole 207, installing the insertion block 208 and the box body 3. Conversely, the box body 3 can be disassembled, and the operation is simple.
