Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane laying technology, and in particular to a waterproof membrane flattening device. Background Technology

[0002] Waterproof membrane is a flexible building material that can be rolled into rolls. It is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist the leakage of external rainwater and groundwater. It is the first line of defense for waterproofing projects and plays a vital role in the entire project.

[0003] After waterproof membrane is applied, air bubbles often remain inside, causing the membrane to bulge or loosen. Therefore, a flattening device is needed to flatten it. The conventional flattening method is to use a flattening roller to roll on the membrane to flatten it. As the frequency of use increases, the surface of the flattening roller will be damaged and will easily adhere to some glue. The glue can also easily attract other debris, requiring regular maintenance and cleaning. However, most existing flattening rollers have a fixed frame structure, which is inconvenient to disassemble, making maintenance and cleaning inconvenient. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] Reference Figure 1-4This utility model provides an embodiment of a waterproof roll flattening device, comprising a movable frame 1, four movable wheels 2 located at the bottom of the movable frame 1 near the four corners, which can be omnidirectional for easy movement; a fixing recess 3 on the movable frame 1, a lifting frame 4 slidably disposed within the fixing recess 3, a flattening roller 5 rotatably connected to the lifting frame 4; a fixing frame 6 fixedly connected to the top of the movable frame 1; a fixing groove 8 at the bottom of the fixing frame 6; a lifting plate 9 slidably connected within the fixing groove 8; an adjusting screw 10 rotatably connected to the top of the lifting plate 9; and a mechanism for adjusting the screw 10. The screw 10 has a threaded groove 11 that fits into the thread. The lifting plate 9 and the fixed groove 8 are nested and slidingly fitted. When the screw 10 rotates and moves down in the threaded groove 11, it can limit and guide the lifting plate 9, making it rise and fall smoothly. The top of the adjusting screw 10 is fixedly connected to a rotating block 12. A handle 13 is provided on one side of the top of the rotating block 12. During operation, the handle 13 is grasped and rotated around the position of the adjusting screw 10, which can drive the rotating block 12 to rotate, thereby driving the adjusting screw 10 to rotate. The top of the lifting frame 4 is fixedly connected to a fixed seat 14. An installation mechanism is provided between the lifting plate 9 and the fixed seat 14.

[0030] The mounting mechanism includes a mounting groove 15 on a fixed base 14 and a mounting block 17 fixedly connected to the bottom of a lifting plate 9. A locking groove 16 is provided on the inner wall of the mounting groove 15. An inner groove 18 is provided at the contact point between the mounting block 17 and the lifting plate 9. An adjusting screw 19 is rotatably connected inside the lifting plate 9. A moving block 20 is nested and slidably connected inside the inner groove 18. The moving block 20 is threaded onto the adjusting screw 19, and a locking block 21 is fixedly connected to the moving block 20. The mounting block 17 and the mounting groove 15 are nested together, and the locking block 21 and the locking groove 16 are also nested together. Two sets of locking grooves 16, inner grooves 18, moving blocks 20, and locking blocks 21 are provided. The threads on both sides of the adjusting screw 19 are reversed. The two moving blocks 20 are connected to the reversed threads on both sides of the adjusting screw 19. A rotating block is fixedly connected to one end of the adjusting screw 19. The lifting plate 9 has a storage groove 22, and the rotating block 23 is located in the storage groove 22. The rotating block 23 has a handle 24, which is located near the edge of the rotating block 23. By grasping the handle 24 and rotating it around the center of the rotating block 23, the rotating block 23 can be rotated. A locking mechanism is provided between the lifting plate 9 and the rotating block 23. During operation, the mounting block 17 is inserted into the mounting groove 15, and the handle 24 is grasped to rotate the rotating block 23. The rotating block 23 rotates the adjusting screw 19, which in turn rotates the two moving blocks 20 in opposite directions. The two moving blocks 20 then move the two locking blocks 21 into the corresponding locking grooves 16, thus completing the positioning and installation of the mounting mechanism. This allows the flattening roller 5 to be installed together with the moving frame 1. Similarly, it can be easily disassembled for maintenance and cleaning of the flattening roller 5.

[0031] A push handle 7 is fixedly connected to one side of the outer surface of the fixed frame 6. The push handle 7 allows the entire structure to be easily pushed and moved.

[0032] The rotating block 23 is provided with a storage groove 25, and the handle 24 is rotatably connected in the storage groove 25. The storage groove 25 allows the rotating block 23 to be built-in. The storage groove 25 can be rotated and stored in the storage groove 25 when the handle 24 is not in use, which improves the safety of the operating structure and prevents accidental contact.

[0033] The locking mechanism includes a threaded groove 26 on the top of the lifting plate 9 and a pin hole 30 on the outer surface of the rotating block 23. A threaded rod 27 is threadedly connected to the threaded groove 26. A rotating block 28 and a pin 29 are fixedly connected to the top and bottom of the threaded rod 27, respectively. The pin 29 and the pin hole 30 are connected by an insertion fit. Multiple pin holes 30 are provided and evenly distributed on the outer surface of the rotating block 23. During operation, rotating the rotating block 28 causes the threaded rod 27 to be screwed into the threaded groove 26. The threaded rod 27 causes the pin 29 to be inserted into the pin hole 30, thereby locking the rotating block 23 and preventing it from rotating, thus ensuring the stability of the structural positioning. Similarly, the locking mechanism can be easily released during operation.

[0034] Working principle: When using the waterproof membrane flattening device, grasp the handle 24 and make it revolve around the center of the rotating block 23. This will cause the rotating block 23 to rotate, which in turn causes the adjusting screw 10 to rotate. The adjusting screw 10, through its engagement with the threaded groove 11, causes the lifting plate 9 to descend. The lifting plate 9 causes the fixed seat 14 to descend, which in turn causes the lifting frame 4 to descend. The lifting frame 4 causes the flattening roller 5 to descend and fit against the surface of the waterproof membrane, pushing the moving frame 1 to move. The flattening roller 5 rolls forward to flatten the waterproof membrane. When it is necessary to maintain and clean the flattening roller 5, open the locking mechanism and then open the installation mechanism. This will separate the lifting frame 4, making it convenient to maintain and clean the flattening roller 5.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
