Description

Technical Field

[0001] The utility model relates to the technical field of coil laying and fixing, in particular to a waterproof coil fixing device. Background Art

[0002] The building waterproof project is a sub-project that ensures the structure of a building (structure) is not invaded by water and the internal space is not damaged by water. The building waterproof project occupies an important position in the entire building project. The building waterproof project involves many parts of the building (structure), such as the basement, wall and floor, wall body, roof, etc. Among them, the laying of waterproof coils can waterproof the positions that need to be waterproofed in the building. When laying the waterproof coils, a fixing device is needed to fix and install them, and then the laying construction is carried out.

[0003] A fixing mechanism for a waterproof coil laying device described in the publication number CN216471162U includes a frame and a rotating shaft rotatably installed on the frame for fixing the waterproof coil. A ratchet is fixedly sleeved on the rotating shaft near the end. A locking mechanism is movably arranged on the frame to cooperate with the ratchet to make the ratchet rotate unidirectionally, and an operating end for controlling the cooperation position of the locking mechanism and the ratchet. In this application, a ratchet and a locking mechanism cooperating with it are arranged at one end of the rotating shaft for fixing the waterproof coil to limit the rotation direction of the rotating shaft. The movement of the locking mechanism can change its contact position with the ratchet, thereby changing the rotation direction of the ratchet and the rotating shaft. Thus, the rotating shaft can be used for both winding and unwinding. The limitation of the rotation direction of the rotating shaft by the locking mechanism makes the rotating shaft always maintain a unique working state, avoiding the excessive freedom of the rotating shaft to rotate back and forth, which affects the work efficiency or causes too much unwinding and improper winding amount when laying the waterproof coil. However, the prior art still has defects:

[0004] In the prior art, after the waterproof coil is fixed on the rotating shaft, the second spring is stretched to the longest. The second spring provides a pulling force to make the pressure roller apply pressure to the waterproof coil. As the thickness of the waterproof coil decreases, the stretching length of the second spring gradually decreases. However, the gradually decreasing pulling force will inevitably result in an increasingly smaller limiting pressure on the waterproof coil, making the limitation of the pressure roller on the waterproof coil not stable enough.

[0029] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] A waterproof coiled material fixing device includes an underframe 1. The underframe 1 is a fixed frame structure on the waterproof coiled material laying device. Support seats 2 are fixedly connected to the upper ends of both ends of the underframe 1. An installation mechanism 3 is arranged between the two support seats 2. The installation mechanism 3 includes a rotating shaft 31 inserted between the two support seats 2. A waterproof coiled material 32 is sleeved in the middle of the rotating shaft 31. An inclined placing groove 33 for cooperating with the rotating shaft 31 is formed on the support seat 2. The rotating shaft 31 is inserted into the waterproof coiled material 32 and then placed on the two support seats 2 through the placing groove 33.

[0031] A compaction roller 4 is arranged between the two end chassis 1. The compaction roller 4 is located at the rear lower part of the waterproof coiled material 32. One end of the waterproof coiled material 32 bypasses the rear side of the compaction roller 4 and extends forward to contact the ground. The compaction roller 4 further squeezes and fits the waterproof coiled material 32 to the ground.

[0032] A fixed seat 5 is arranged at the rear side between the two end support seats 2. The upper end of the fixed seat 5 is inclined. A tightening mechanism 6 is arranged on the fixed seat 5. The tightening mechanism 6 includes a fixed shaft 61 arranged at the upper rear end of the waterproof coiled material 32. A tightening roller 62 is rotatably connected in the middle of the fixed shaft 61. The tightening roller 62 abuts against the waterproof coiled material 32, applying pressure to the unwinding of the waterproof coiled material 32 to make the unwinding smoother.

[0033] An installation plate 7 is arranged at the upper end of the tightening roller 62. The installation plate 7 is inclined. There is a lifting mechanism 8. The lifting mechanism 8 is arranged on the installation plate 7. The lifting mechanism 8 includes a cylinder 81 and a sliding column 82. The cylinder 81 is fixedly connected to the middle of the upper end of the fixed seat 5. The lower end of the cylinder 81 is fixedly connected to the middle of the upper end of the installation plate 7. The two sliding columns 82 are fixedly connected to both sides of the upper end of the installation plate 7. The upper ends of the sliding columns 82 penetrate through the fixed seat 5, and the cylinder 81 drives the installation plate 7 to move up and down.

[0034] A elastic force mechanism 9 is arranged on the installation plate 7. The elastic force mechanism 9 includes a movable plate 91 arranged at the upper end of the installation plate 7. The movable plate 91 is inclined. The cylinder 81 and the lower ends of the sliding columns 82 are both movably inserted into the movable plate 91. Fixed rods 92 are fixedly connected to both sides of the lower end of the movable plate 91. The lower ends of the fixed rods 92 penetrate through the installation plate 7 and are fixedly sleeved on one end of the fixed shaft 61. A baffle 93 is fixedly sleeved in the middle of the fixed rod 92. A spring 94 is arranged between the upper end of the baffle 93 and the lower end of the installation plate 7. The spring 94 is sleeved on the fixed rod 92. A touch switch 95 is fixedly connected to the lower end of the fixed rod 92. The lower end of the touch switch 95 contacts the surface of the waterproof coiled material 32. The cylinder 81 drives the installation plate 7 to move downward, thereby driving the tightening roller 62 to move downward to abut against the waterproof coiled material 32. The spring 94 provides an elastic force to the tightening roller 62. The tightening roller 62 drives the fixed rod 92 to move upward to compress the spring 94. The movable plate 91 moves under the limitation of the fixed rod 92. When the touch switch 95 cannot contact the surface of the waterproof coiled material 32, the cylinder 81 starts to move downward continuously to drive the tightening roller 62 to abut against the waterproof coiled material 32, making the pressure of the tightening roller 62 on the waterproof coiled material 32 more stable and making the unwinding of the waterproof coiled material 32 smoother.

[0035] When the present utility model is specifically implemented, as Figures 1-6 shown, in use, the chassis 1 is the fixed frame structure on the waterproof coiled material laying device. The rotating shaft 31 is inserted into the waterproof coiled material 32 and then placed on the two end support seats 2 through the placing groove 33. One end of the waterproof coiled material 32 bypasses the rear side of the compaction roller 4 and extends forward to contact the ground. The compaction roller 4 further squeezes and fits the waterproof coiled material 32 to the ground.

[0036] The air cylinder 81 drives the mounting plate 7 to move downward, thereby driving the pressing roller 62 to move downward to press against the waterproof coiled material 32. The pressing roller 62 rotates on the fixed shaft 61 following the unwinding of the waterproof coiled material 32. The spring 94 provides an elastic force to the pressing roller 62. The pressing roller 62 drives the fixed rod 92 to move upward to compress the spring 94. The movable plate 91 moves under the limitation of the fixed rod 92. When the unwinding diameter of the waterproof coiled material 32 becomes smaller and the touch switch 95 cannot touch the surface of the waterproof coiled material 32, the air cylinder 81 starts to move downward continuously to drive the pressing roller 62 to press against the waterproof coiled material 32, making the pressure of the pressing roller 62 on the waterproof coiled material 32 more stable and making the unwinding of the waterproof coiled material 32 smoother.
