Background Technology

[0002] During construction, a large amount of building materials such as steel bars, formwork, concrete, and steel reinforcement are needed. Manual loading and unloading of materials on vehicles is a common and important process, but this process is fraught with safety risks.

[0003] Due to the complex working environment, when loading and unloading materials on transport vehicles, workers sometimes need to stand on the roof or the edge of the vehicle. Their footing is unstable, which can easily lead to slipping and falling. In addition, there are no suitable suspension points for the safety belts during the operation, which makes it difficult for workers to work at heights and poses a risk of falling from heights. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a movable device that protects personnel on material transport vehicles and provides safety belt suspension points for manual loading and unloading of materials. The device is easy to install, disassemble, and carry, and can significantly improve construction safety.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a safety belt hanging and moving device for manual loading and unloading of materials at construction sites, comprising symmetrically distributed telescopic poles, the telescopic end of which moves along the ground height direction above the fixed end, and is supported and fixed by a pin passing laterally through the fixed end of the telescopic pole, forming a suspended working area between the symmetrical telescopic poles, and also including a bearing crossbar and a support mechanism, the two ends of the bearing crossbar being fixedly connected to the telescopic ends of the symmetrical telescopic poles, the bearing crossbar being placed horizontally, the height of the bearing crossbar being adjusted by the telescopic poles, the support mechanism being connected to the outer wall of the fixed end of the telescopic pole for supporting the fixed end of the telescopic pole, and a differential fall arrester being fixedly connected to the bearing crossbar.

[0006] Furthermore, the support mechanism includes a support frame formed by horizontal support rods and vertical support rods, and a reinforcing rod connected between the support frame and the fixed end of the telescopic upright. The reinforcing rod is inclined and is connected to the telescopic upright and the vertical support rod by a swivel fastener.

[0007] Furthermore, the support frame is arranged at uniform intervals on the side away from the suspended working area, and forms multiple triangular support structures with the fixed end of the telescopic pole.

[0008] Furthermore, one end of the horizontal support rod is connected to the outer wall of the fixed end of the telescopic pole, and the other end of the horizontal support rod extends away from the telescopic pole. The vertical support rod is connected to the extended end of the horizontal support rod, and the horizontal support rod is fixedly connected to the fixed end of the vertical support rod and the telescopic pole respectively using cross fasteners.

[0009] Furthermore, the crossbar and the telescopic end of the telescopic pole are fixedly connected by a cross-shaped fastener.

[0010] Furthermore, the bottom end of the telescopic pole is equipped with a caster wheel.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows:

[0012] 1. The structure is simple and the manufacturing cost is low. The frame is erected by using steel pipes and fasteners on site, and the finished differential fall arrestor and base rollers are assembled and fixed. The installation is simple, the disassembly is easy, and it is convenient to carry and has a high reusability.

[0013] 2. This device can effectively solve the risk of falling from heights for workers loading and unloading materials from trucks at construction sites, ensuring necessary safety for workers when working at heights.

[0014] 3. The detachable and movable design allows for easy adjustment of the position according to the different locations of loading and unloading materials, solving the problem of the risk of falling from height due to the lack of safety belt suspension points during the current material loading and unloading process, while improving the efficiency of construction operations.

[0021] like Figure 1-4 As shown, a safety belt mounting and moving device for manual loading and unloading of materials at construction sites includes symmetrically distributed telescopic poles 1. The telescopic end of the telescopic pole 1 moves along the ground height direction above the fixed end and is supported and fixed to the telescopic end by a pin that passes laterally through the fixed end of the telescopic pole 1. A suspended working area is formed between the symmetrical telescopic poles 1. It also includes a load-bearing crossbar 2 and a support mechanism 3. The two ends of the load-bearing crossbar 2 are fixedly connected to the telescopic ends of the symmetrical telescopic poles 1. The load-bearing crossbar 2 is placed horizontally, and its height is adjusted by the telescopic poles 1. The support mechanism 3 is connected to the outer wall of the fixed end of the telescopic pole 1 for support. A differential fall arrester 4 is fixedly connected to the fixed end of the telescopic pole 1 and the bearing crossbar 2. The bearing crossbar 2 and the telescopic end of the telescopic pole 1 are fixedly connected by a cross fastener 10. The bottom end of the telescopic pole 1 is equipped with a movable wheel 11. The distance between the symmetrical telescopic poles 1 is adjusted and locked by the cross fasteners 10 on the outer side walls of both ends of the bearing crossbar 2. At the same time, the telescopic end of the telescopic pole 1 moves up and down within its fixed end to adjust the height of the bearing crossbar 2 and limit the height of the differential fall arrester 4, so that the height and width of the suspended working area are fixed. After the device is moved to the vehicle loading and unloading position by the movable wheel 11, the support mechanism 3 increases the support stability of the device.

[0022] like Figure 3 and Figure 4As shown, to improve the stability of the device and facilitate its movement for position adjustment, the support mechanism 3 includes a support frame 7 formed by horizontal support rods 5 and vertical support rods 6, and a reinforcing rod 8 connecting the support frame 7 to the fixed end of the telescopic pole 1. The reinforcing rod 8 is inclined and connected to the telescopic pole 1 and the vertical support rod 6 by a swivel fastener 9. The support frame 7 is evenly spaced on the side away from the suspended working area, forming multiple triangular support structures with the fixed end of the telescopic pole 1. One end of the horizontal support rod 5 is connected to the outer wall of the fixed end of the telescopic pole 1, and the other end of the horizontal support rod 5 extends away from the telescopic pole 1. One side of pole 1 extends, and vertical support pole 6 is connected to the extension end of horizontal support pole 5. Horizontal support pole 5 is fixedly connected to the fixed end of vertical support pole 6 and telescopic pole 1 using cross fasteners 10. Support mechanism 3 extends and supports in three directions on the outside of telescopic pole 1, providing support to the side away from the vehicle and the two sides parallel to the front and rear of the vehicle. Support frame 7 is fixedly connected to the fixed end of telescopic pole 1 using cross fasteners 10, providing stable support for telescopic pole 1. With the flexible steering support of reinforcing pole 8, vertical support pole 6 can be lifted and moved to a designated position using moving wheels 11. After moving to the position, the steering fasteners 9 are tightened again, improving work efficiency.

[0023] In practical use, the length of the top load-bearing crossbar 2 is selected according to the width of the material loading and unloading vehicle. The telescopic end of the telescopic pole 1 is firmly connected to both ends of the load-bearing crossbar 2 through the cross fastener 10. The differential fall arrester 4 is fixed at the position of 1 / 3 and 2 / 3 of the length of the top crossbar. The height of the telescopic end of the telescopic pole 1 is adjusted according to the height of the material loading and unloading and the on-site usage. The height of the differential fall arrester 4 can be determined by oneself. The telescopic end of the telescopic pole 1 is moved up and down within its fixed end for adjustment. The telescopic end is supported and fixed by the pin passing through the fixed end of the telescopic pole 1 laterally.

[0024] The bottom of the telescopic pole 1 is assembled with two 6-inch casters 11. After moving the suspended work area of ​​the device to the material loading and unloading position, the brake of the caster 11 should be stepped on to lock the caster 11. After use, the caster 11 can be disassembled and reused.

[0025] An anti-tipping structure is erected at the bottom of the telescopic pole 1 by the support mechanism 3. The structure is erected in three directions at the bottom of the support pole, with four short steel pipes in each direction. It is constructed using two vertical support poles 6, one horizontal support pole 5, and one diagonal reinforcing pole 8. The height-adjustable telescopic pole 1 is reinforced and connected to any one of the vertical support poles 6 of the support frame 7 using cross-shaped fasteners 10. The diagonal reinforcing pole 8 and the vertical support pole 6 are connected by a swivel fastener 9 to solve the problem of steering without force. At the same time, when moving the device, part of the cross-shaped fastener 10 on the horizontal support pole 5 needs to be removed. The vertical support pole 6 can be lifted using the swivel fastener 9 and moved to the designated position using the moving wheels 11. After moving to the position, the cross-shaped fastener 10 is tightened again. The workers attach their safety belts to the differential fall arrestor 4 and continue working, which improves work efficiency and effectively solves the risk of falling from height in high-altitude operations.
