Description

Technical Field

[0001] The utility model belongs to the field of construction engineering, and in particular relates to a waterproof coiled material conveying and paving device. Background Art

[0002] In rail transit or structural engineering construction, a single or double layer of waterproofing membrane is often required to be laid on the outside of the structure. The construction scope includes the entire surface area of ​​the structure, and the construction workload is large. In the process of waterproofing membrane construction, a crane is generally used to place the rolled waterproofing membrane in one location, and then the workers carry it to the laying location. If it is in a special location such as a groove or a structural top plate, the vehicle cannot enter and it needs to be completely carried manually. In addition, most of the current laying is done by manually spreading the waterproofing membrane, or using steel pipes, one person holds up the waterproofing membrane and the other pulls it outward to spread it. Since a single roll of waterproofing membrane is heavy, during the construction of waterproofing membrane, workers' manual handling and laying will consume a lot of labor, the workers' workload is large, the labor intensity is high, and the operation efficiency is low.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0019] This embodiment includes a vehicle body, which includes two wheels 1 and a frame. Unlike conventional vehicles, the frame of the present invention includes an upper frame and a lower frame that are rotatably connected together, and the lower frame is connected to the wheel 1. Preferably, the wheel 1 uses a solid tire. Among them, the lower frame includes two vertical support rods 2, and a transverse support rod 3 is fixedly connected between the two vertical support rods 2. An oblique support rod 4 is connected in the middle of the transverse support rod 3, and the upper end of the oblique support rod 4 is rotatably connected to a horizontal gear 5.

[0020] The upper frame includes two parallel handle bars 6 in a natural state. A handle 7 is provided at one end of the handle bar 6 close to the gear 5. The handle 7 is tilted downward and is provided with a non-slip silicone sleeve. In order to enhance the stability of the upper frame, an oblique connecting rod 16 is preferably fixedly connected between the handle bar 6 and the vertical connecting rod 10. The other end of the handle bar 6 is vertically connected to the clamping short rod 8, and the end of the clamping short rod 8 is rotatably connected to the rotating drum 9. Preferably, the rotating drum 9 adopts a bearing A, wherein the inner ring of the bearing A is fixed to the end of the clamping short rod 8, and the outer ring of the bearing A is rotatable. The middle part of the handle bar 6 is fixedly connected downward to the vertical connecting rod 10, and the vertical connecting rod 10 is rotatably connected to the vertical support rod 2. Preferably, the upper frame and the lower frame are rotatably connected together via a bearing B15. Specifically, the upper end of the vertical support rod 2 is fixedly connected to the inner ring of the bearing B15, and the lower end of the vertical connecting rod 10 is fixedly connected to the outer ring of the bearing B15. The outer ring of the bearing B15 is rotatable, thereby realizing the rotational connection between the upper frame and the lower frame.

[0021] Horizontal racks 12 are hinged on both handle bars 6 through pins 11. The two racks 12 are located on both sides of the gear 5 and mesh with the gear 5. Torsion springs 13 are installed on both pins 11. The two legs 14 of the torsion springs 13 are blocked by blocking columns 17 fixed on the handle bars 6 and the racks 12 respectively. Preload forces are applied to the two torsion springs 13 to make the racks 12 close to the gear 5. This preload force ensures that the racks 12 always press the gear 5, mesh with the gear 5, and do not separate from the gear 5. The preload forces on the two torsion springs 13 are equal, so in a natural state without external force, the two handle bars 6 are parallel to each other.

[0022] When in use, push the vehicle body to the waterproof membrane drum position, the worker holds the handle 7 and rotates the two handle rods 6 to separate the two rotating drums 9 outward, and at the same time, let the rotating drums 9 on both sides be respectively located at the opening positions at both ends of the waterproof membrane drum, and then rotate the two handle rods 6 to let the rotating drums 9 move inward, so that the two rotating drums 9 are respectively extended into the waterproof membrane drum, and then the waterproof membrane drum is picked up by the two rotating drums 9, and the vehicle body is pushed to transport the waterproof membrane to the paving position, and then the worker pulls one end of the waterproof membrane outward for paving. After the paving is completed, the worker lowers the position of the rotating drum 9 and places the waterproof membrane in a suitable position, and then rotates the two handle rods 6 to let the rotating drum 9 come out of the waterproof membrane drum. After releasing the hands, the two handle rods 6 return to a parallel state due to the elastic force of the torsion spring 13. During the whole process, the pre-tightening force of the torsion spring 13 makes the two racks 12 always press the gear 5 and not separate from the gear 5.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
