Description

Technical Field

[0001] This invention relates to the field of waterproof membrane laying technology, specifically to a waterproof membrane laying device. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up and serve as a leak-proof connection between the foundation of the project and the building. They are the first line of defense for waterproofing the entire project and play a vital role in the overall project.

[0003] During road paving, waterproof membranes need to be laid on the road to ensure its waterproofness. The existing laying method usually involves operators unrolling the waterproof membrane little by little, applying a cold primer to the road in advance, and then using a flame gun for hot-melt laying. This laying method usually requires multiple operators to work at the same time. At the same time, the use of flame guns often leads to safety accidents, reducing the convenience of laying waterproof membranes and increasing labor and laying costs.

[0004] Combining the above issues, we find that existing waterproof membrane laying devices on the market are difficult to avoid all of the problems mentioned above during use. Even if they can solve the problems, they require the use of external tools, thus failing to achieve the desired effect. Therefore, we propose a waterproof membrane laying device.

[0036] The laying mechanism 2 includes a pretreatment unit 21, which is located inside the first housing 12 and the second housing 13. The pretreatment unit 21 is used to unwind and level the waterproof membrane.

[0037] The pretreatment unit 21 includes a first cross 2101, which is snapped into the interior of a second housing 13. A second cross 2113 is snapped into the interior of the second housing 13. Four placement rods 2112 are snapped between the first cross 2101 and the second cross 2113. Bolts 2111 are threaded to both ends of each placement rod 2112, which are snapped between the first cross 2101 and the second cross 2113 via the bolts 2111. A first support roller 2116 and a second support roller 211 are rotatably connected inside the first housing 12 and the second housing 13, respectively. 5. Drive wheels 2117 are fixedly mounted on the surfaces of the first support roller 2116, the second support roller 2115, the first pulley group 17, and the second pulley group 18. Belts 2122 are installed inside both the first box body 12 and the second box body 13. The two drive wheels 2117 are connected by the belts 2122. The first support roller 2116 rotates through the cooperation of the first pulley group 17, the belts 2122, and the drive wheels 2117. The second support roller 2115 rotates through the cooperation of the second pulley group 18, the belts 2122, and the drive wheels 2117. A support plate 21 is fixedly mounted on the inner wall of the first box body 12. 14. A first friction plate 2119 is slidably installed on the inner wall of the first box 12. A copper plate 2118 is fixedly installed on the bottom of the first friction plate 2119. A second friction plate 2120 is slidably installed on the surface of the first friction plate 2119.

Friction pads are adhered to the surfaces of the first friction plate 2119 and the second friction plate 2120. By setting the pretreatment unit 21, it is possible to drive the anti- During the unwinding process of the waterproof membrane, the heat generated by the friction between the first friction plate 2119 and the second friction plate 2120 preheats and heat-melts the waterproof membrane. After the waterproof membrane passes the leveling plate 2121, it is leveled, reducing wrinkles that could lead to poor installation. When laying the waterproof membrane, multiple operators are not required. The waterproof membrane can be preheated in advance during the laying process, which increases the heat-melting effect in the next step and ensures the flatness of the waterproof membrane before laying, thus improving the efficiency of laying the waterproof membrane.

[0038] A tension spring 2105 is fixedly installed on the inner wall of the second cross 2113. A movable plate 2106 is fixedly installed on one end of the tension spring 2105. A connecting rod 2107 is fixedly installed on one side of the movable plate 2106. One end of the connecting rod 2107 extends to the outer side of the second cross 2113 and is fixedly installed with a positioning plate 2108. A positioning rod 2109 is fixedly installed on one side of the positioning plate 2108. The inner wall of the second box 13 has four positioning holes 2110 that cooperate with the positioning rods 2109. The tension spring 2105, movable plate 2106, connecting rod 2107, positioning plate 2108, positioning rod 2109, and positioning hole 2110 work together to allow the positioning rod 2109 to fully enter the inner cavity of the positioning hole 2110, thereby positioning the second cross 2113 and the waterproof membrane. This causes the waterproof membrane to rotate during unwinding, ensuring stability during unwinding. It also allows for the replacement of one roll of waterproof membrane with another after one roll is used up, ensuring stability during waterproof membrane installation and improving convenience.

[0039] A rotating rod 2103 is fixedly installed on one side of both the first cross 2101 and the second cross 2113. A bearing 2104 is fixedly installed on the rotating rod 2103. A retaining ring 2102 is fixedly installed on the outer ring of the bearing 2104. The retaining ring 2102 is engaged with the inner cavity of the second box 13. Through the coordinated use of the rotating rod 2103, the bearing 2104 and the retaining ring 2102, it is possible to make it more convenient for operators to replace another roll of waterproof membrane and ensure the stability during replacement.

[0040] A slide rod 2123 is fixedly installed on the inner wall of the first box 12. A sliding sleeve 2124 is slidably installed on the surface of the slide rod 2123. An mounting plate 2127 is fixedly installed on one side of the sliding sleeve 2124. The mounting plate 2127 is fixedly installed on the first friction plate 2119. A spring 2125 is fixedly installed on the top of the sliding sleeve 2124. One end of the spring 2125 is fixedly installed on the inner wall of the first box 12. The spring 2125 is sleeved on the slide rod 2123. A hook 2126 is fixedly installed on the top of the mounting plate 2127. The hook 2126 is made of elastic metal material. By setting up hook 2126, which is hung on the first box 12, the copper plate 2118, the first friction plate 2119 and the second friction plate 2120 are lifted, making it convenient for the operator to pass the waterproof membrane between the copper plate 2118 and the support plate 2114. By setting up sliding rod 2123, sliding sleeve 2124, mounting plate 2127 and spring 2125, the copper plate 2118 and the support plate 2114 can apply a certain clamping force to the waterproof membrane, so that the heat can be better transferred to the waterproof membrane, and the waterproof membrane can be better preheated and leveled.

[0041] A motor 2131 is fixedly mounted on one side of the mounting plate 2127. An eccentric plate 2132 is fixedly mounted on the output end of the motor 2131. A drive shaft 2135 is fixedly mounted on one side of the eccentric plate 2132. A sliding plate 2133 is connected to the surface of the drive shaft 2135. A movable groove 2134 is provided on one side of the sliding plate 2133. The drive shaft 2135 is disposed in the movable groove 2134. A connecting rod 2136 is fixedly mounted on one side of the sliding plate 2133. One end of the connecting rod 2136 is fixedly mounted on the surface of the second friction plate 2120. A limit plate 2128 is fixedly mounted on one side of the mounting plate 2127. Two guide rods 2129 are slidably mounted in the inner cavity of the limit plate 2128. One end of each guide rod 2129 is fixedly mounted on the second friction plate 2120. On the surface of plate 20, a flat plate 2121 is fixedly installed on one side of the support plate 2114 and the copper plate 2118. Guide grooves 2130 are opened on both sides of the limiting plate 2128, and guide rods 2129 are slidably installed in the guide grooves 2130. By setting up a motor 2131, an eccentric plate 2132, a transmission shaft 2135, a sliding plate 2133, a movable plate 2106, and a connecting rod 2136, friction can be generated between the first friction plate 2119 and the second friction plate 2120 to preheat and heat-melt the waterproof membrane. By setting up the limiting plate 2128, the guide rod 2129, and the guide grooves 2130, the second friction plate 2120 can be made more stable during movement, ensuring that the second friction plate 2120 will not deviate during movement.

[0042] When waterproof membrane needs to be laid, the waterproof membrane is fitted onto the placement rod 2112. The placement rod 2112 is then installed between the first cross 2101 and the second cross 2113 using bolts 2111. After installation, the positioning plate 2108 is pulled, causing the positioning rod 2109 to move. Simultaneously, the positioning plate 2108 moves, causing the connecting rod 2107 to move. The movement of the connecting rod 2107 causes the movable plate 2106 to pull the tension spring 2105. At this point, the user moves the first cross 2101 and the second cross 2113, placing them inside the second housing 13. Simultaneously, the first cross 2101 and the second cross 2113 engage the retaining ring 2102 inside the second housing 13. The reaction force of the tension spring 2105 then... The positioning rod 2109 is moved into one of the positioning holes 2110 to position one of the waterproof membranes. The user places one end of the waterproof membrane on the second support roller 2115, passes one end of the waterproof membrane between the support plate 2114 and the copper plate 2118, and then places it on the first support roller 2116. The waterproof membrane is then passed through the through hole on the bottom plate 11 and the first box 12 to the bottom of the bottom plate 11. After one end of the waterproof membrane passes through the bottom of the bottom plate 11, the bottom plate 11 lays the waterproof membrane as it moves. The reaction force of the spring 2125 drives the sliding sleeve 2124 to move on the sliding rod 2123. The movement of the sliding sleeve 2124 drives the mounting plate 2127 to move. The mounting plate 2127 drives the first friction plate 2123 to move. When the first friction plate 2119 moves, it drives the copper plate 2118 to move, causing the copper plate 2118 and the support plate 2114 to exert a slight clamping force on the waterproof membrane. At this time, the second cover plate 14 is installed, and then the first cover plate 15 is closed via a pivot. The user starts the motor 2131 using an external control switch and a battery. The motor 2131 drives the eccentric plate 2132 to rotate, which in turn drives the transmission shaft 2135 to rotate. The transmission shaft 2135 drives the sliding plate 2133 to move via the movable groove 2134. The sliding plate 2133 drives the connecting rod 2136 to move, which in turn drives the second friction plate 2120 to move, causing the second friction plate 2120 to reciprocate. This reciprocating motion generates friction between the second friction plate 2119 and the first friction plate 2119, thus generating heat. While the motor 2131 is running, the user pushes the first housing 12 using the handle 16. The first housing 12 moves the base plate 11, which moves via the first pulley group 17 and the second pulley group 18. The first pulley group 17 and the second pulley group 18 drive the transmission wheel 2117 to rotate. Through the cooperation of the transmission wheel 2117 on the first pulley group 17, the second pulley group 18, the first support roller 2116, and the second support roller 2115 with the belt 2122, the first support roller 2116 and the second support roller 2115 are driven to rotate, thereby driving the waterproof membrane to unwind. During the unwinding process of the waterproof membrane, the heat generated by the friction between the first friction plate 2119 and the second friction plate 2120 has a certain preheating and heat-melting effect on the waterproof membrane.After the waterproof membrane passes through position 2121 on the flat plate, it should be leveled to prevent wrinkles that could lead to poor installation. During the installation process, the waterproof membrane can be preheated to enhance the heat-fusion effect in the next step, ensuring its flatness before installation and improving installation efficiency.

[0043] The laying mechanism 2 also includes a hot melt drying unit 22, which is located inside the first box 12. The hot melt drying unit 22 is used to hot melt the waterproof membrane and dry the cold primer. The hot melt drying unit 22 is used in conjunction with the pretreatment unit 21.

[0044] The hot melt drying unit 22 includes a hot melt blower 2204, which is fixedly installed in the inner cavity of the first box 12.

One end of each oil outlet pipe 2211 extends to the outside of the first box 12 and to the bottom of the base plate 11. A nozzle 2201 is fixedly connected to one end of each oil outlet pipe 2211. A housing 2212 is fixedly installed on one side of the hot melt blower 2204. A collection box 2203 is fixedly installed on one side of 2212. Several air outlet pipes 2205 are fixedly connected to one side of the collection box 2203.

One end of the air outlet pipe 2205 is fixedly connected to the air outlet bucket 2202. The hot melt blower 2204 is used in conjunction with the first support roller 2116. By setting up the hot melt drying unit 22, multiple operators are not required when laying the waterproof membrane. At the same time, operators do not need to use a flame gun for hot melting, which ensures both safety and efficiency during laying and reduces the cost of laying the waterproof membrane.

[0045] A refueling pipe 2209 is fixedly connected to one side of the fuel tank 2206. One end of the refueling pipe 2209 extends to the outside of the first box 12. The inner cavity of the refueling pipe 2209 is plugged with a cap 2210. By setting the refueling pipe 2209 and the cap 2210, it is convenient for users to add cold base oil into the fuel tank 2206.

[0046] After the waterproof membrane is preheated, the hot melt blower 2204 and oil pump 2207 are started simultaneously. The hot air generated by the hot melt blower 2204 melts the waterproof membrane, while the oil pump 2207 draws the cold primer oil in the oil tank 2206 into the inner cavity of the oil outlet pipe 2211. The cold primer oil is then sprayed onto the road surface through the nozzle 2201. After spraying, the device is pushed forward. While the hot melt blower 2204 melts the waterproof membrane, a certain amount of hot air is collected by the air collection box 2203. The hot air then enters the box 2212 and then the air outlet pipe 2205. It is then blown out through the air outlet 2202 to dry the cold primer oil. After drying, the melted waterproof membrane is laid on the cold primer oil by the forward movement of the device, achieving the purpose of convenient laying.

[0047] A cleaning mechanism 3 is provided at the bottom of the base plate 11. The cleaning mechanism 3 works in conjunction with the hot melt drying unit 22. The cleaning mechanism 3 is used to clean the stones and dust in the paving area.

[0048] The cleaning mechanism 3 includes two cleaning pipes 304. One end of the cleaning pipe 304 is fixedly connected to one side of the housing 2212, and the other end of the cleaning pipe 304 passes through the outside of the first housing 12 and extends to the bottom of the base plate 11. One end of the cleaning pipe 304 is fixedly connected to an air outlet box 303. A stone cleaning plate 301 is fixedly installed on the bottom of the base plate 11. The stone cleaning plate 301 is distributed in a triangular pattern. By setting up the cleaning mechanism 3, the operator does not need to clean the laying position in advance, which ensures the convenience of laying the waterproof membrane.

[0049] A brush plate 302 is fixedly installed on the bottom of the base plate 11. The brush plate 302 is distributed in a triangle and the bottom of the brush plate 302 is set as a brush. By setting the brush plate 302, the brush plate 302 can sweep the paved road surface, remove dust, and facilitate the laying of waterproof membrane.

[0050] During the operation of the device, the stone cleaning plate 301 can clear the gravel to both sides, while the brush plate 302 sweeps the dust to the position that the air outlet box 303 can reach. During the operation of the hot melt blower 2204, hot air enters the cleaning pipe 304 through the box 2212, and then enters the inner cavity of the air outlet box 303 through the cleaning pipe 304. Finally, it is blown out from the air outlet box 303, blowing the dust and some fine sand and gravel particles to both sides of the laying position, ensuring the cleanliness of the laying position. Therefore, the operator does not need to clean beforehand, ensuring the convenience of laying waterproof membrane.
