Description

Technical Field

[0001] The invention belongs to the technical field of roll material construction, and in particular relates to a roller device for paving self-adhesive waterproof roll materials. Background Art

[0002] Self-adhesive waterproofing membrane is a flexible waterproofing material that can be rolled into a roll. It has good waterproof properties and can effectively prevent water penetration. It is also self-adhesive and can be directly laid on surfaces such as walls and floors without the use of adhesives. At present, the laying construction of self-adhesive waterproofing membranes generally requires multiple people to complete; at least one person controls the rolling process of the membrane, and at least one person compacts the laid coils in time to prevent hollowing. This makes the construction speed relatively slow, and due to the poor effect of manual compaction and poor adhesion, it is easy to cause quality defects such as leakage and hollowing, thereby reducing the reliability of waterproofing. The second defect of manual compaction is that when the waterproofing membrane is laid on a slope, the direction of manual force needs to be changed at any time, which makes it difficult to control. Based on this, there is a need for a construction equipment that can lay self-adhesive waterproofing membranes efficiently and with high quality. Summary of the Invention

[0003] The purpose of the present invention is to provide a roller device for laying self-adhesive waterproof membranes. By arranging a downward pressure device on the roller for laying waterproof membranes, it replaces manual downward pressure, thereby improving construction efficiency and saving manpower; in addition, the above-mentioned downward pressure device can adjust the downward pressure angle so that it can still perform the above-mentioned work when laying waterproof membranes on a sloped surface.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is: a roller device for laying self-adhesive waterproof roll materials, comprising a frame, a guide wheel installed at the front end of the frame, a film-applying roller installed at the rear end of the frame, and a storage roller arranged on the frame and used for storing waterproof roll materials; it is characterized in that it also includes a lower pressure plate unit arranged on the frame and used to press down the film-applying roller, a rotating column unit for making the lower pressure plate unit rotate along the axial direction of the film-applying roller, and a cylinder for adjusting the height of the lower pressure plate unit.

[0005] A further preferred technical solution is that: the lower pressure plate unit includes an arc-shaped plate, and a lower pressure column arranged on the arc-shaped plate; the rotating column unit includes a mounting block arranged on the cylinder column, a rotating column for connecting the lower pressure column, and an arc-shaped rotating groove arranged on the mounting block and used to install the rotating column.

[0006] A further preferred technical solution is that: the rotating column unit further includes a rotating block for rotating the rotating column, and a telescopic block portion provided between the rotating block and the rotating column.

[0007] A further preferred technical solution is that: a rotating shaft is provided axially on the film-laminating roller; a rotating shaft groove for installing the rotating shaft is provided on the frame, and a sinking plate portion for supporting the rotating shaft is provided on the rotating shaft groove.

[0008] A further preferred technical solution is that: a pulling rope for connecting to the inner side of the rotating block is provided on the sinking plate portion; and a rough surface is provided on the inner side of the rotating block.

[0009] A further preferred technical solution is that the telescopic block portion includes a groove body provided on the inner side of the rotating block and used for sleeve-engaging the rotating column, and a return spring provided in the groove body and used for pushing the rotating column outward.

[0010] A further preferred technical solution is that the sinking plate portion includes a sinking plate, a sinking plate support arranged at the lower end of the sinking plate, and a buffer spring for pushing the sinking plate support outward.

[0011] A further preferred technical solution is that the sinking plate portion further includes a pull-down plate arranged on the side of the sinking plate support and used for connecting the pull rope.

[0012] A further preferred technical solution is that: the rear end of the frame is provided with an armrest extending laterally.

[0013] A method for laying a self-adhesive waterproof membrane comprises the following steps:

[0014] S1. Clean the base layer and apply the base modifier of the waterproof membrane to the base layer until it cools down and does not stick to the touch;

[0015] S2. For locations with insufficient moisture-proofing, such as external corner lines and detailed connection points, follow the standards or design requirements;

[0016] S3. Use the roller device for laying the self-adhesive waterproof membrane to pre-lay the waterproof membrane to the reference point, making sure the paper protective film faces downward;

[0017] S4, peel off the protective film from one end of the waterproof membrane, pull the peeled protective film down evenly, and at the same time stick a part of the peeled protective film on the pre-applied base modifier, and lay it while pulling. Pay attention to the exhaust pipe when laying, so that the waterproof membrane and the base are more closely connected, and pay attention to aligning with the reference point at all times.

[0018] The present invention is also beneficial in that:

[0019] First, after the lower pressure plate completes pressing down on the film-laminating roller, the rotating column is automatically locked together by the transmission action of the pulling rope, which has the function of automatically locking the inclination angle of the lower pressure plate; its advantage is that it utilizes the sinking effect of the sinking plate which acts as a buffer when the film-laminating roller sinks, so as to drive the rotating block above to move inward by pulling the rope to lock the current position of the rotating column.

[0020] Second, the rotating column slides in the arc-shaped rotating groove to adjust the inclination angle of the lower pressure plate, and has the function of stepless angle adjustment;

[0021] Third, the contact point between the lower pressure plate and the film-laminating roller has a curved plate that matches the curvature of the film-laminating roller, so the force is applied evenly;

[0022] Fourth, there is a handrail extending to the side on the rear side of the frame to facilitate workers to work on the side. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

[0039] Embodiment: A roller device for laying self-adhesive waterproofing membranes, comprising a frame 1, a guide wheel 2 mounted on the front end of the frame 1, a film-applying roller 3 mounted on the rear end of the frame 1, and a storage roller 4 provided on the frame 1 and used to store waterproofing membranes; characterized in that it also comprises a lower pressing plate unit 5 provided on the frame 1 and used to press down the film-applying roller 3, a rotating column unit 6 used to rotate the lower pressing plate unit 5 along the axial direction of the film-applying roller 3, and a cylinder 7 used to adjust the height of the lower pressing plate unit 5. Figure 1-3As shown, during construction, workers only need to push the frame 1 forward to lay the waterproofing membrane A on the ground, and can work on an inclined surface with a certain inclination angle. The working principle is that the upper part of the waterproofing membrane A is wrapped around the storage roller 4, and the upper part of the lower end is attached to but not attached to the film-applying roller 3. The guide wheel 2 and the lowest point of the film-applying roller 3 are located on the same horizontal plane. When the frame 1 is pushed forward, the guide wheel 2 and the film-applying roller 3 roll forward together. Under the downward pressure of the film-applying roller 3, the self-adhesiveness of the waterproofing membrane A causes it to stick to the ground, and drives the storage roller 4 to rotate, thereby releasing more waterproofing membrane A, thus achieving the purpose of laying the waterproofing membrane A on the ground. Among them, the electrical components used to control the lifting and lowering of the cylinder 7 are common control systems in the prior art.

[0040] In the above process, the waterproof membrane A cannot be well adhered to the ground by the gravity of the film-laminating roller 3 alone, so a lower pressure plate unit 5 is set on the side of the frame 1 close to the film-laminating roller 3 to apply a downward force to the film-laminating roller 3 so that the waterproof membrane A can be more tightly adhered to the ground, reducing hollowing, water leakage and other phenomena.

[0041] Preferably, the rear end of the frame 1 is provided with a handrail 104 extending to the side. Figure 4 When the staff walks behind the frame 1, they may step on the waterproof membrane A that has just been pasted on the ground, which may destroy the uniformity of the adhesion between the waterproof membrane A and the ground. After the handrail 104 is provided, it is convenient for the staff to push the frame 1 sideways and avoid stepping directly on the waterproof membrane A.

[0042] <Operating Principle of Lower Plate Unit 5 and Rotating Column Unit 6>

[0043] The lower pressure plate unit 5 includes an arc-shaped plate 501 and a lower pressure column 502 provided on the arc-shaped plate 501; the rotating column unit 6 includes a mounting block 601 provided on the cylinder 7 column, a rotating column 602 for connecting the lower pressure column 502, and an arc-shaped rotating groove 603 provided on the mounting block 601 and for mounting the rotating column 602. Figure 5-6 The curvature of the curved plate 501 matches the curvature of the cylindrical side of the film-applying roller 3, ensuring uniform pressure from the curved plate 501 on the film-applying roller 3. The cylinder 7, via the mounting block 601, applies a downward pressure to the downward pressure column 502, which is then transmitted to the film-applying roller 3 via the curved plate 501. A rotating column 602 is also positioned between the mounting block 601 and the downward pressure column 502. This rotating column 602 rotates along the circumferential direction of the film-applying roller 3, thereby changing the angle at which the curved plate 501 acts on the film-applying roller 3. This ensures that the pressure applied by the curved plate 501 is perpendicular to the ground surface even when the film-applying roller 3 is operating on a slope, facilitating the adhesion of the waterproof membrane A to the ground.

[0044] refer to Figure 7 The arc-shaped rotating groove 603 provided in the mounting block 601 has an arc similar to the arc of the cylindrical body of the film-laminating roller 3 , so that the rotating column 602 can rotate along the circumferential direction of the film-laminating roller 3 .

[0045] The rotating column unit 6 further includes a rotating block 604 for rotating the rotating column 602, and a telescopic block portion 605 disposed between the rotating block 604 and the rotating column 602. Figure 8-10 The rotating block 604 is located on the outside of the mounting block 601. One of its functions is to facilitate the staff to adjust the position of the rotating column 602. The second function is to fit together with the outer side of the mounting block 601 through the contraction of the telescopic block 605, and fix the current position of the rotating column 602 through friction to fix the inclination angle of the force exerted by the arc plate 501 on the film roller 3.

[0046] <How the film roller 3 is set on the frame 1>

[0047] The film-applying roller 3 is provided with a rotating shaft 301 in the axial direction; the frame 1 is provided with a rotating shaft groove 101 for installing the rotating shaft 301, and the rotating shaft groove 101 is provided with a sinking plate portion 102 for supporting the rotating shaft 301. Figure 11 A rotating shaft 301 is provided on the side of the film-applying roller 3, and the axis of the rotating shaft 301 coincides with the axis of the film-applying roller 3. The radius of the rotating shaft 301 is smaller than that of the film-applying roller 3. The rotating shaft 301 is inserted into the rotating shaft groove 101 to achieve the effect of installing the film-applying roller 3 inside the frame 1. Preferably, one rotating shaft 301 is provided on each film-applying roller 3, and correspondingly, a rotating shaft groove 101 is provided on both sides of the frame 1 for installing the rotating shaft 301.

[0048] A sinking plate portion 102 is provided on the inner bottom surface of the rotating shaft groove 101 for supporting the rotating shaft 301. The sinking plate portion 102 is similar to the suspension component of a vehicle, so that the film roller 3 can sink to a certain extent, so that it can fit more closely to the ground under the downward pressure of the arc plate 501, thereby playing the role of tightly fitting the waterproof membrane A on the ground.

[0049] <Principle of Locking the Inclination Angle of the Rotating Column 602 While Pressing Down the Laminating Roller 3>

[0050] The sinking plate 102 is provided with a pull rope 103 for connecting to the inner side of the rotating block 604; the inner side of the rotating block 604 is provided with a rough surface. When the arc plate 501 presses down the film roller 3, the sinking plate 102 moves downward, thereby driving the pull rope 103 to move downward and pull the rotating block 604 inward. Figure 9-10The inner side of the rotating block 604 is in contact with the outer side of the mounting block 601. The inner side of the rotating block 604 is provided with a rough surface. When the rotating block 604 is in contact with the outer side of the mounting block 601, the friction force generated therebetween is sufficient to fix the rotating column 602 in its current position, thereby achieving the purpose of locking its tilt angle.

[0051] The telescopic block 605 includes a slot 605a disposed on the inner side of the rotating block 604 and adapted to receive the rotating column 602, and a return spring 605b disposed within the slot 605a and adapted to prop up the rotating column 602. When the pull cord 103 pulls the rotating block 604 inward, the rotating block 604 causes the slot 605a to move inward, thereby compressing the return spring 605b and causing it to deform until the rotating block 604 is fully in contact with the mounting block 601. To adjust the angle of the rotating column 602 based on the current ground tilt, the downward pressure on the film-applying roller 3 must first be released. At this point, the inward force of the pull cord 103 pulling the rotating block 604 disappears. With the outward push of the return spring 605b, the rotating block 604 no longer adheres to the outer side of the mounting block 601, allowing the angle of the rotating column 602 to be adjusted again.

[0052] refer to Figure 12 The sinking plate portion 102 includes a sinking plate 102a, a sinking plate support 102b provided at the lower end of the sinking plate 102a, and a buffer spring 102c for pushing the sinking plate support 102b outward. The curvature of the sinking plate 102a is equal to the curvature of the outer side surface of the rotating shaft 301. Unlike the curved plate 501, the concave surface of the sinking plate 102a faces upward, while the concave surface of the curved plate 501 faces downward. The purpose of the sinking plate 102a is to support the rotating shaft 301. When the curved plate 501 presses down on the film-applying roller 3, the rotating shaft 301 presses the sinking plate 102a downward, causing the sinking plate support 102b to sink and compress the buffer spring 102c to contract. When the arc-shaped plate 501 stops pressing the film-laminating roller 3, the buffer spring 102c pushes the sinking plate support 102b outward, causing the sinking plate support 102b to move upward, so that the sinking plate 102a returns to its original position.

[0053] The sinking plate portion 102 further includes a pull-down plate 102d provided on the side of the sinking plate support 102b and used to connect the pull rope 103. When the sinking plate support 102b sinks, the pull-down plate 102d is driven to sink together, thereby pulling the pull rope 103 downward, and a portion of the pull rope 103 moves into the internal cavity of the frame body 1, so that the outer end also pulls the rotating block 604 inward, making it fit together with the mounting block 601. Preferably, refer to Figure 12-13A number of fixed pulleys are provided in the cavity of the frame 1 for installing the pulling rope 103 and guiding the extension direction of the pulling rope 103 so that its lower end is always vertically connected to the lower pull plate 102d and its upper end is always vertically connected to the rotating block 604, making its pulling force more uniform.

[0054] Preferably, the frame 1 is provided with a lower pressure plate unit 5 and a rotating column unit 6 on both sides of the film-laminating roller 3, and a linkage mechanism is provided between the two, so that the lower pressure plate unit 5 and the rotating column unit 6 on the left and right sides can operate synchronously, so that the film-laminating roller 3 is subjected to more uniform force.

[0055] Preferably, the storage roller 4 is provided with a ratchet mechanism, Figure 1 The storage roller 4 can only rotate counterclockwise but not clockwise, thereby avoiding accidentally storing the waterproof membrane A that has been attached to the ground during movement.

[0056] The laying method of self-adhesive waterproof membrane is as follows:

[0057] S1. Clean the base layer and apply the base modifier of the waterproof membrane to the base layer until it cools down and does not stick to the touch;

[0058] S2. For locations with insufficient moisture-proofing, such as external corner lines and detailed connection points, follow the standards or design requirements;

[0059] S3. Use the roller device for laying the self-adhesive waterproof membrane to pre-lay the waterproof membrane to the reference point, making sure the paper protective film faces downward;

[0060] S4, peel off the protective film from one end of the waterproof membrane, pull the peeled protective film down evenly, and at the same time stick a part of the peeled protective film on the pre-applied base modifier, and lay it while pulling. Pay attention to the exhaust pipe when laying, so that the waterproof membrane and the base are more closely connected, and pay attention to aligning with the reference point at all times.
