Description

Technical Field

[0001] The invention relates to the field of waterproofing, and in particular to a roof waterproofing coiled material laying device. Background Art

[0002] Waterproof membrane is a kind of flexible building material commonly used in building walls, roofs, tunnels, roads and other construction projects. It can resist external rainwater, groundwater leakage, etc.

[0003] At present, there are mainly the following methods for laying waterproof membranes: hot melt method, cold adhesive method, self-adhesive method, wet laying method, mechanical fixing method, empty laying method, etc. Among them, the hot melt method is the most common. The method is to heat the bottom surface and the base layer of the membrane by flame to melt the asphalt at the bottom of the membrane, and then stick it on the material that needs waterproofing. It is now commonly used in the laying construction of waterproof membranes in construction projects such as roofs and roofs. Usually, the staff operates manually or uses a laying device. When laying manually, the staff first needs to pre-lay the waterproof membrane, lay the waterproof membrane first in the place where waterproofing is required, and determine the laying direction of the waterproof membrane according to the length and width of the waterproof plane required, and then roll up the pre-laid waterproof membrane and bake it on the side with asphalt. The temperature of the flame will melt the asphalt The waterproofing membrane that has been baked is then quickly laid so that the waterproofing membrane is closely attached to the plane that needs waterproofing, and finally the side of each waterproofing membrane is baked and sealed. This manual waterproofing membrane laying construction usually has low construction efficiency. When using a laying device for laying, people cannot observe the heating condition of the waterproofing membrane well when pushing the cart, and a slow pushing speed will make the heating time too long, which will cause the waterproofing membrane to burn. Therefore, when people push manually, they may push the cart too fast to avoid burning the waterproofing membrane. However, if the forward speed is too fast, it will cause uneven heating of the membrane, which will cause the membrane to be poorly bonded. Therefore, a roof waterproofing membrane laying device that can prevent the uneven heating of the waterproofing membrane caused by the excessive speed of the cart is first designed. Summary of the invention

DETAILED DESCRIPTION

[0032] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0033] Example 1: A roof waterproofing membrane laying device, please refer to Figure 1-Figure 5The vehicle machine 1 includes a vehicle machine 1, a first connecting member 11 is fixed at the front of the vehicle machine 1, a sliding block 15 is slidably connected to the front of the first connecting member 11, a rotating block 151 is rotatably connected to the front of the sliding block 15, a flame head 14 is rotatably connected to the rotating block 151, a second connecting member 161 is rotatably connected to the lower part of the vehicle machine 1, a torsion spring 17 is fixedly connected to the vehicle machine 1 on both the left and right sides of the second connecting member 161, a shaft is rotatably connected to the front of the second connecting member 161, a waterproofing coil 16 is wound on the shaft, and asphalt is provided on the side of the waterproofing coil 16 that needs to be heated, and the waterproofing coil 16 contains asphalt when it is wound. The green side faces outward, and wheels are rotatably connected to the left and right sides of the vehicle machine 1. A first bidirectional screw 110 is fixed on the side where the wheels are close to each other, and the first bidirectional screw 110 is rotatably connected to the vehicle machine 1. Air valves 112 are fixed on the inner sides of the left and right sides of the vehicle machine 1. The air valves 112 are retractable and have openings. Connecting rings 111 are fixed to the retractable ends of the air valves 112. The connecting rings 111 are threadedly connected to the corresponding first bidirectional screws 110. A fuel tank 12 is fixed to the rear of the vehicle machine 1, and a flattening component capable of flattening the waterproof coiled material 16 is connected to the fuel tank 12.

[0034] See also Figure 1-Figure 3 , further comprising a fuel pipe 13 , one end of which is connected to the flame head 14 , and the other end of the fuel pipe 13 passes upward through the rotating block 151 and is connected to the upper side of the fuel tank 12 .

[0035] See also Figure 2 , further comprising a switch 113, which is disposed on the upper side of the fuel tank 12, and the flame head 14 is electrically connected to the switch 113 through a control module.

[0036] See also Figure 4 The flattening assembly includes two sliding members 191, which are slidably connected to the rear side of the fuel tank 12. A pressure spring 19 is fixedly connected between the sliding member 191 and the fuel tank 12. A connecting column 181 is fixed to the lower side of the sliding member 191, and an extrusion column 18 is rotatably connected between the connecting columns 181.

[0037] When people need to lay the waterproofing coiled material 16 on the roof, the device can be used for operation. First, people manually rotate the rotating block 151, and the rotating block 151 drives the flame head 14 to rotate, so that the flame head 14 can be aimed at the waterproofing coiled material 16. Then people manually press the switch 113 and open the air valve 112. The switch 113 controls the flame head 14 to start through the control module, so that the flame head 14 starts to spray fire. The flame head 14 sprays fire at the waterproofing coiled material 16, so that the asphalt on the waterproofing coiled material 16 melts. Then people manually push the vehicle machine 1 forward, and the vehicle machine 1 drives the second connecting member 161 to drive the waterproofing coiled material 16 to move forward. The heated asphalt will adhere to the roof that needs to be waterproofed, so that the waterproofing coiled material 16 is attached to the roof. 7, the second connecting member 161 can be prevented from tilting when the vehicle 1 is traveling, so that the second connecting member 161 can drive the waterproof coiled material 16 to be in close contact with the roof. When the extrusion column 18 at the rear of the vehicle 1 contacts the laid waterproof coiled material 16, the extrusion column 18 will squeeze the waterproof coiled material 16 downward, so that the air between the waterproof coiled material 16 and the roof is discharged, so that the waterproof coiled material 16 and the roof are more closely attached. Under the action of the pressure spring 19, the extrusion column 18 can press the waterproof coiled material 16 tightly. People manually push the vehicle 1 forward, and the wheel of the vehicle 1 rotates, and the wheel drives the first bidirectional screw 110 to rotate. The connecting ring 111 is threadedly connected to the corresponding first bidirectional screw 110, so that the connecting ring 111 starts to move toward each other. The connecting ring 111 drives the telescopic end of the air valve 112 to extend because the opening size of the air valve 112 is fixed, so the maximum value of the rate of gas exchange inside and outside the air valve 112 is fixed, so that the fastest speed of the telescopic end of the air valve 112 is fixed, and then the maximum speed of the connecting ring 111 moving on the first bidirectional screw 110 is fixed. Therefore, when people push the vehicle machine 1 too fast, the rotation of the first bidirectional screw 110 will be hindered. When people push the vehicle machine 1, they can feel the obstruction by hand, so that people know that the moving speed of the vehicle machine 1 is too fast, and then people can reduce the speed of pushing the vehicle machine 1, so as to prevent the waterproof membrane 16 from being insufficiently and unevenly heated. When the waterproof membrane 16 is laid After completion, people close the air valve 112, and then press the switch 113 again to close the flame head 14. The above operation uses the air valve 112 to control the maximum speed at which the connecting ring 111 moves on the first bidirectional screw 110. When people push the vehicle machine 1 too fast, the pushing of the vehicle machine 1 will be hindered, so that people know that the moving speed of the vehicle machine 1 is too fast, and then people will reduce the pushing speed. Because people cannot observe the heating condition of the waterproof coiled material 16 well when pushing the vehicle machine 1, people cannot manually control the pushing speed of the vehicle machine 1 well. When pushing, the moving speed may be too fast, resulting in the disadvantage of uneven heating of the waterproof coiled material 16. By setting the extrusion column 18 to extrude the waterproof coiled material 16,The waterproofing membrane 16 can be more closely attached to the roof, and the waterproofing effect is better.

[0038] Example 2: Based on Example 1, please refer to Figure 6-Figure 7 , and also includes a stabilizing mechanism that can limit the left and right movement of the vehicle 1 when laying the waterproof membrane 16 to avoid uneven paving. The stabilizing mechanism includes two second telescopic members 281, and the second telescopic members 281 are respectively fixed to the left and right sides of the vehicle 1. A telescopic rod 24 is fixedly connected between the second telescopic member 281 and its telescopic end. A connecting block 28 is fixed to the lower side of the second telescopic member 281. The connecting block 28 is set in an L shape. The lower side of the connecting block 28 is provided with an inclined surface away from each other. The lower side of the telescopic end of the second telescopic member 281 is fixed with a first telescopic member 25 A compression spring 251 is provided inside the first telescopic member 25, so that the first telescopic member 25 is elastic, and a blocking block 29 is fixed on the side where the telescopic ends of the first telescopic member 25 are close to each other. The blocking block 29 is squeezed and matched with the inclined surface of the lower part of the corresponding connecting block 28. A second fixing member 271 is fixed on the lower side of the telescopic end of the first telescopic member 25, and three rollers 26 are rotatably connected to the second fixing member 271. A plurality of rubber members 27 are circumferentially distributed on the rollers 26. A driving component that can drive the telescopic end of the second telescopic member 281 to extend and retract is connected to the vehicle machine 1.

[0039] See also Figure 6-Figure 7 The driving assembly includes a connecting frame 201, which is fixed inside the vehicle machine 1. A first dual-axis motor 2 is fixed on the upper part of the connecting frame 201. The output shafts on the left and right sides of the first dual-axis motor 2 are fixed with rotating rods 21. The sides of the rotating rods 21 that are away from each other are threadedly connected with one-way screws 22. The one-way screws 22 are rotatably connected between the corresponding second telescopic member 281 and its telescopic end. A first fixing member 23 is fixed between the telescopic rod 24 and the one-way screw 22.

[0040] When people push the vehicle machine 1, it is difficult to control the manual operation, so the vehicle machine 1 cannot be controlled to move in a straight line. The vehicle machine 1 may deviate during the laying process. Therefore, a stabilizing mechanism is provided to enable the vehicle machine 1 to keep moving forward. The following is its working principle: when people lay the waterproof membrane 16 and need to push the vehicle machine 1 in a straight line, the rubber parts 27 are in contact with the roof that needs to be waterproofed. Because the friction between the rubber parts 27 and the roof is very large, the vehicle machine 1 can be prevented from deviating when it moves forward. Under the action of the compression spring 251, the compression spring 251 can prevent the first telescopic part 25 from retracting during the operation of the vehicle machine 1, so that the rubber part 27 is in close contact with the roof. When the rubber part 27 is in contact with the roof , the blocking block 29 is not separated from the connecting block 28. When people need to drive the vehicle machine 1 to turn to lay the next waterproof membrane 16, people can start the output shaft of the first double-axis motor 2 to reverse. The first double-axis motor 2 reverses to drive the rotating rod 21 to reverse. The rotating rod 21 is threadedly connected with the corresponding one-way screw 22, so that the one-way screw 22 moves toward the side close to each other, and the one-way screw 22 drives the first fixing member 23 to move toward the side close to each other. The first fixing member 23 drives the telescopic end of the telescopic rod 24 to retract, and the telescopic rod 24 drives the telescopic end of the second telescopic member 281 to retract, and the second telescopic member 281 drives the first telescopic member 25 to move toward the side close to each other, and the first telescopic member 25 drives the blocking blocks 29 to move toward each other. The blocking block 29 and the connecting block 28 move on one side, and the inclined surfaces of the blocking block 29 and the connecting block 28 are squeezed, so that the blocking block 29 is squeezed and moved upward, and the blocking block 29 drives the telescopic end of the first telescopic member 25 to retract, and the compression spring 251 is compressed. The telescopic end of the first telescopic member 25 drives the second fixing member 271 and then drives the rubber member 27 to move upward, so that the rubber member 27 is separated from the roof. Then people turn off the first dual-axis motor 2, and then they can manually drive the vehicle machine 1 to turn. When people want to push the vehicle machine 1 to move in a straight line again, they start the first dual-axis motor 2 to rotate forward, and the output shaft of the first dual-axis motor 2 drives the rotating rod 21 to rotate forward. The rotating rod 21 and the corresponding one-way screw 22 are threadedly connected, so that the one-way screw 22 moves away from each other. The one-way screw 22 drives the first fixing member 23 to move toward the side away from each other, the first fixing member 23 drives the telescopic end of the telescopic rod 24 to extend, the telescopic rod 24 drives the telescopic end of the second telescopic member 281 to extend, the second telescopic member 281 drives the first telescopic member 25 to move toward the side away from each other, the first telescopic member 25 drives the blocking block 29 to move toward the side away from each other, so that the blocking block 29 and the inclined surface of the connecting block 28 are separated, and then because the roller 26 and the rubber member 27 have their own weight, the roller 26 drives the second fixing member 271 and then drives the telescopic end of the first telescopic member 25 to extend, the compression spring 251 is reset, and the rubber member 27 is attached to the roof, and people turn off the first dual-axis motor 2,Then the vehicle 1 can be driven to move in a straight line. The above operation is performed by setting the rubber member 27. When the rubber member 27 is in contact with the roof, the friction between the rubber member 27 and the roof is large, thereby preventing the vehicle 1 from deviating when the vehicle 1 moves in a straight line, thereby making the waterproof membrane 16 more flat.

[0041] See also Figure 8-Figure 10 , and also includes a lifting mechanism that can lift the entire device so that the device can move the position of the vehicle machine 1 left and right when the stabilizing mechanism is restricted. The lifting mechanism includes a telescopic column 301, which is fixed to the lower side of the right part of the vehicle machine 1. The lower side of the telescopic column 301 is fixedly connected to the second dual-axis motor 3, and the output shafts on the front and rear sides of the second dual-axis motor 3 are fixedly connected to the first rotating column 37. Four third telescopic members 36 are fixedly connected to the left and right sides of the lower part of the vehicle machine 1. Every two third telescopic members 36 form a group. The two groups of third telescopic members 36 corresponding to the left and right sides are rotatably connected to the crawler 31 through the transmission wheel. The third fixed member 35 is fixedly connected between the third telescopic members 36 around each crawler 31. The first rotating column 37 passes through the transmission wheel on the right side of the corresponding crawler 31 and is fixedly connected thereto. The first rotating column 37 is rotatably connected to the corresponding third telescopic member 36. A second rotating column 371 is fixedly connected between the transmission wheels on the left side of the crawler 31. The first rotating column 37 is connected to a moving component that allows the crawler 31 to move up and down.

[0042] See also Figure 8-Figure 10 The moving component includes four first bevel gears 32, two of which are fixedly connected to the sides of the first rotating column 37 away from each other, and the other two first bevel gears 32 are fixedly connected to the front and rear sides of the second rotating column 371 respectively. The second rotating column 371 is rotatably connected to the third telescopic member 36 on the left. Two second bidirectional screws 34 are fixedly connected to the lower sides of the left and right sides of the vehicle machine 1. The second bidirectional screws 34 are threadedly connected to the second bevel gears 33, and the second bevel gears 33 are meshed with the corresponding first bevel gears 32.

[0043] When laying the waterproof membrane 16, the distance between each waterproof membrane 16 is roughly the same, and people will have a large deviation when manually pushing the cart machine 1, which will result in a large difference in the distance between the waterproof membranes 16, which will lead to waste of the waterproof membrane 16 or poor waterproof effect. Therefore, a lifting mechanism is provided that can lift the cart machine 1 and allow the cart machine 1 to move left and right. The following is its working principle: when the cart machine 1 needs to move left and right, people can start the second dual-axis motor 3, and the output shafts on the front and rear sides of the second dual-axis motor 3 both drive the corresponding first rotating column 37 to rotate, and the first rotating column 37 drives the corresponding first bevel gear 32 to rotate, and at the same time, the first rotating column 37 drives the corresponding right transmission wheel of the crawler 31 Rotate, the rotation of the transmission wheel on the right drives the corresponding crawler 31 to rotate and then drives the transmission wheel on the left to rotate, the transmission wheel on the left drives the second rotating column 371 to rotate, the second rotating column 371 drives the first bevel gear 32 on the left to rotate, the first bevel gear 32 and the corresponding second bevel gear 33 are meshed, so that the second bevel gear 33 starts to rotate, the second bevel gear 33 and the corresponding second bidirectional screw 34 are threadedly connected, so that the second bevel gear 33 starts to move downward while rotating, the second bevel gear 33 drives the first bevel gear 32 to move downward, the first bevel gear 32 on the right drives the corresponding first rotating column 37 to move downward, the first bevel gear 32 on the left drives the second rotating column 371 to move downward, and the first rotating column The first bevel gear 32 and the second bevel gear 33 are both unable to move downward, so that the first bevel gear 32 can no longer drive the first rotating column 37 to move downward, and the second bevel gear 33 can no longer move downward, but the second bevel gear 33 continues to rotate, so that the second bidirectional screw 34 starts to move upward, and the second bidirectional screw 34 jointly drives the vehicle machine 1 to move upward, so that the wheels of the vehicle machine 1 are separated from the roof, and the crawler 31 continues to rotate, and the crawler 31 will drive the vehicle machine 1 to move left and right. When the second bevel gear 33 moves to the lowest part of the thread line of the second bidirectional screw 34, the second bevel gear 33 continues to rotate, and the second bidirectional screw 34 starts to move upward. The screw rods 34 will move downward in the opposite direction, and the second bidirectional screw rods 34 will drive the vehicle machine 1 to move downward and reset. When the crawler belt 31 drives the vehicle machine 1 to move to the specified position, the wheels of the vehicle machine 1 just touch the roof, and the second bidirectional screw rods 34 touch the roof. The second bevel gears 33 continue to rotate, which will cause the second bevel gears 33 to move upward. The second bevel gears 33 on the left will drive the second rotating column 371 and then drive the transmission wheel on the left to move upward. The second bevel gears 33 on the right will drive the first rotating column 37 and then drive the transmission wheel on the right to move upward. The transmission wheels will drive the crawler belt 31 to move upward and reset, so that the crawler belt 31 is separated from the roof, thereby completing the left and right movement of the vehicle machine 1, and then people turn off the second dual-axis motor 3.Then people can lay the waterproofing coil 16 again. The above operation drives the first rotating column 37 to rotate through the output shaft of the second dual-axis motor 3. The first rotating column 37 drives the track 31 and then drives the second rotating column 371 to rotate, so that the first bevel gear 32 rotates, and then the second bevel gear 33 rotates. The second bevel gear 33 and the second bidirectional screw 34 are threadedly connected, and the track 31 moves downward, so that the track 31 contacts the roof. At the same time, the second bevel gear 33 rotates, so that the second bidirectional screw 34 drives the vehicle 1 to move upward, and the rotation of the track 31 drives the vehicle 1 to move left and right, thereby avoiding the situation where people manually push the vehicle 1, causing a large position error of the vehicle 1.

[0044] See also Figure 11-Figure 12 , and also includes a rotating mechanism that can rotate the flame head 14 so that the flame head 14 can perform flame sealing on the side of the waterproof membrane 16. The rotating mechanism includes a third connecting member 4, which is slidably connected to the middle of the upper rear side of the vehicle machine 1, and a spur gear 42 is rotatably connected to the lower front side of the third connecting member 4. The lower side of the spur gear 42 is fixedly connected to the flame head 14, and racks 41 are fixed on both sides of the upper front side of the first connecting member 11, and the racks 41 and the spur gears 42 are meshed with each other.

[0045] When the waterproofing membrane 16 is completely laid, people need to perform edge sealing on the positions where the waterproofing membrane 16 contacts each other. Edge sealing can prevent water from entering through the gaps at the left and right edges, thereby achieving a better waterproofing effect. Therefore, the device is provided with a rotating mechanism that can rotate the flame head 14. The following is its working principle: when people need to perform edge sealing on the left and right sides of the waterproofing membrane 16, people can manually drive the sliding block 15 to move to the left, and the sliding block 15 drives the rotating block 151 to drive the flame head 14 to move to the left. The flame head 14 drives the spur gear 42 to drive the third connecting member 4 to move to the left. The spur gear 42 is meshed with the rack 41 on the left, so that the spur gear 42 starts to rotate clockwise, and the spur gear 42 drives the flame head 14 to rotate clockwise. Then people press the switch 113, and the switch 113 controls the flame head 14 to start, so that the flame head 14 can spray fire at the edge on the left side of the waterproofing membrane 16. At the same time, people push the vehicle machine 1 forward, thereby The left side of the material 16 is sealed, and then people press the switch 113 to turn off the flame head 14. People manually drive the sliding block 15 to move right, and the sliding block 15 drives the rotating block 151 to drive the flame head 14 to move right. The flame head 14 drives the spur gear 42 and then drives the third connecting member 4 to move right. The spur gear 42 is meshed with the rack 41 on the right, so that the spur gear 42 starts to rotate counterclockwise. The spur gear 42 drives the flame head 14 to rotate counterclockwise, and then people press the switch 113, the switch 113 controls the flame spray head 14 to start, so that the flame spray head 14 can spray fire at the edge of the right side of the waterproof membrane 16, and at the same time, people push the vehicle machine 1 forward to seal the right side of the waterproof membrane 16. The above operation is carried out by the spur gear 42 and the racks 41 on the left and right sides meshing with each other, so that the spur gear 42 drives the flame spray head 14 to rotate, so that the flame spray head 14 can spray fire on the left and right edges of the waterproof membrane 16, thereby completing the edge sealing of the waterproof membrane 16.
