Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material construction equipment, in particular to a rolling device for laying waterproof coiled materials. Background Art

[0002] Waterproof membranes are mainly used for building walls, roofs, tunnels, roads, landfills, etc. They are a kind of flexible building material products that can be rolled into a roll to resist the leakage of external rainwater and groundwater. At present, after the waterproof membrane is initially laid, workers are usually required to use a rolling device to compact the laid waterproof material, which can not only expel the air between the waterproof material and the ground, but also further strengthen the adhesion between the waterproof material and the ground. The existing rolling device is generally composed of a cart frame and a load-bearing roller. The worker pushes the cart frame to make the roller roll. However, during the actual use of the rolling device, since the roller can only move in a straight line, when changing the rolling position, the worker often needs to manually drag it. Because the roller is relatively heavy, manual dragging is not only labor-intensive, but also during the dragging process, the edges of the roller at both ends are prone to scratching the surface of the waterproof material, thereby reducing the laying quality of the waterproof material.

[0022] Furthermore, a counterweight box 8 with an upward opening is placed on the top of the movable box body 1, which not only increases the weight of the entire device to further increase the rolling pressure of the pressure roller 2, but also serves as a storage space for construction tools for waterproof membranes.

[0023] Furthermore, a plurality of circular positioning grooves 81 are provided at the bottom of the counterweight box body 8, and a positioning protrusion 11 that engages with the positioning grooves 81 is fixedly provided on the top of the mobile box body 1, which can position the counterweight box body 8 on the top of the mobile box body 1 to ensure that the counterweight box body 8 moves stably with the mobile box body 1.

[0024] Furthermore, U-shaped handles 82 are fixedly provided on both sides of the counterweight box body 8, which can facilitate the staff to remove and place the counterweight box body 8 from the top of the mobile box body 1.

[0025] Furthermore, the pushcart frame 3 includes a pair of support plates 31 fixed to the top of the movable box body 1, and handrails 32 at both ends of which are fixedly connected to the inverted L-shaped plate 71. The lower portion of the support plates 31 is inclined upward and the upper portion is horizontally curved. The handrails 32 are fixedly connected to the upper portion of the support plates 31. By using the above-mentioned pushcart frame 3, it is convenient for workers to easily push the movable box body 1 and the pressure roller 2 to roll the waterproof material.

[0026] Furthermore, a pair of handles 33 are fixedly connected to the side walls of the handrail 32, and the handles 33 are perpendicular to the handrail 32, which can facilitate the staff to drag the mobile box body 1 to change the rolling position.

[0027] Furthermore, the flip assembly 7 includes a lifting arrangement on the inverted L-shaped plate 71, a pair of connecting rods 72 that are hinged to the inverted L-shaped plate 71 and have their other ends hinged to the two flip arms 5, a screw rod 73 that is vertically rotatable and is arranged on the top of the movable box body 1 and passes through the inverted L-shaped plate 71, and a nut 74 that is fixed to the inverted L-shaped plate 71 and is threadedly connected to the screw rod 73. The flip arms 5 at one end of the two rotating shafts 4 are respectively hinged to the two connecting rods 72. The nut 74 and the connecting rod 72 are respectively located on the adjacent horizontal and vertical surfaces behind the inverted L-shaped plate 71. The adjacent horizontal and vertical surfaces in front of the inverted L-shaped plate 71 respectively contact the top and side of the movable box body 1. The thread of the screw rod 73 is trapezoidal, and can lock the nut 74 before and after the screw rod 73 rotates to maintain the angular position of the flip arm 5.

[0028] Furthermore, an N-shaped plate 12 is fixedly provided on the top of the movable box body 1, and the screw rod 73 and the nut 74 are located inside the N-shaped plate 12. The two sides of the inverted L-shaped plate 71 slide in contact with the inner sides of the N-shaped plate 12 respectively, which can not only further ensure the lifting stability of the inverted L-shaped plate 71, but also protect the transmission safety of the screw rod 73 and the nut 74 to a certain extent.

[0029] Furthermore, the upper end of the screw rod 73 rotates through the top of the N-shaped plate 12 and is fixedly connected to a rotating handle 75, which can facilitate the staff to control the rotation of the screw rod 73.

[0030] The working principle of this embodiment is as follows:

[0031] When it is necessary to change the rolling position, first crank the handle 75 by hand to rotate the screw rod 73, and then the nut 74 threadedly connected to the screw rod 73 drives the inverted L-shaped plate 71 to slide downward along the screw rod 73. Since the inverted L-shaped plate 71 and the two flip arms 5 are respectively hinged with the connecting rod 72, the two connecting rods 72 will push the two flip arms 5 to flip until the two flip arms 5 are vertically parallel. Moreover, since these two flip arms 5 and the other two flip arms 5 are respectively connected to the two rotating shafts 4, the four flip arms 5 will be vertically parallel together. Finally, the rollers 6 on the four flip arms 5 will support and lift the entire movable box body 1 and make the pressure roller 2 suspended in the air. At this time, the worker can not only easily drag the movable box body 1 to move in the vertical direction of the rolling of the pressure roller 2, but also the suspended pressure roller 2 cannot scratch the surface of the waterproof material of the inverted 71 during the dragging process, thereby conveniently and safely changing the rolling processing position of the device.
