Description

Technical Field

[0001] The invention relates to the field of waterproof construction, and in particular to a TSR waterproof coiled material auxiliary laying device for underground engineering construction. Background Art

[0002] Patent No. CN108756089B discloses a high-efficiency waterproofing membrane laying device, which is used in the field of waterproofing construction. The key points of its technical solution are: it includes a main beam frame, on which a discharge roller, a pressure roller and a pressure wheel that contact the surface to be laid are rotatably connected through a first rotating shaft, a second rotating shaft and a third rotating shaft respectively, and the waterproofing membrane is rolled up on the discharge roller. A hot melting device is provided on the main beam frame, and the end of the waterproofing membrane away from the discharge roller passes over the pressure roller and contacts the surface to be laid. An anti-overturning device is connected to one end of the main beam frame in the forward direction; the technical effects are: 1. The waterproofing membrane can be put down while being continuously hot-melted on the surface to be laid, which greatly improves the laying efficiency of the waterproofing membrane; 2. The tripod and the main beam frame form a triangular structure, which makes the whole device highly stable and not easy to tip over, thereby improving the laying stability of the waterproofing membrane.

[0003] Although the device can quickly lay the coiled material on the surface to be laid, the range of the coiled material baked by the flame sprayed by the hot melt nozzle is fixed, and it is difficult to ensure that the coiled material is heated evenly. Moreover, when the device stops moving, if the staff cannot close the hot melt nozzle in time, the sprayed flame will continue to burn the coiled material, which may easily burn the coiled material. Summary of the invention

[0004] In order to solve the above problems, it is necessary to design a TSR waterproof membrane auxiliary laying device for underground engineering construction.

[0005] The technical implementation scheme of the present invention is: a TSR waterproofing membrane auxiliary laying device for underground engineering construction, including a vehicle body, a front wheel shaft, a fixed discharge rod, a guide wheel, a front pressure wheel, a rear wheel shaft, a rear pressure wheel, a handrail, a gas tank, an air guide pipe, a placement frame, a rotating rod, a valve, a fixed conduit, a flamethrower, a swing mechanism and an automatic fire-off mechanism.

[0008] Furthermore, it also includes a slow-stop mechanism, which is used to slow down the closing speed of the automatic flame-off mechanism when laying is completed, so that the last laid coil receives enough heat.

[0009] Furthermore, the slow stop mechanism includes a vertical slide, a connecting rod, a sliding rod, a ratchet bar, a ratchet and a U-shaped fixed rod. The vertical slide is fixed on the placement rack, a sliding rod is slidably provided in the vertical slide, the sliding rod is connected to the lifting rack through a connecting rod, a ratchet bar is provided on the sliding rod, a U-shaped fixed rod is fixed on the placement rack, and a ratchet is dampingly connected to the U-shaped fixed rod.

[0014] The present invention has the following beneficial effects:

[0015] 1. When laying the waterproof roll material, the present invention first flattens the waterproof roll material before heating, and the waterproof roll material is heated after passing through the flame nozzle, and the rear pressure wheel rolls the waterproof roll material again to make the waterproof roll material stick to the ground, thereby realizing the function of laying the waterproof roll material.

[0016] 2. During the movement of the vehicle body, the sliding ball will move along the slide groove on the rotating guide column, and at the same time will drive the flame-spout to swing left and right, so that the flame-spout can evenly heat the waterproof membrane, thus realizing the function of swinging the flame-spout left and right.

[0017] 3. When the vehicle body stops moving, if the flame nozzle continues to heat the waterproof membrane, the waterproof membrane is likely to be damaged. When the vehicle body in the present application stops moving, the cam is set downward, the connecting spring will pull the lifting frame downward, and the descent of the lifting frame will push the sliding frame outward, and the sliding frame will release the restriction on the swing block and the rotating rod. The torsion spring will drive the rotating rod and the swing block to swing downward and close the valve at the same time, thereby realizing the function of automatically closing the valve.

[0018] 4. When the vehicle body stops moving, the lifting frame will be pulled downward by the connecting spring, and the sliding rod and ratchet bar fixedly connected to the rear side of the lifting frame will move downward accordingly. The ratchet bar will be blocked by the ratchet during the downward movement. The lifting frame will slide downward under the pulling force of the connecting spring and will be resisted by the ratchet, which will slow down the downward movement of the lifting frame and the closing speed of the valve, so that the flame nozzle can heat the last laid waterproof membrane.

[0019] 5. When the vehicle body moves, the collecting brush can sweep the debris on the front side into the collecting frame in the first fixed frame, thereby realizing the function of cleaning the debris on the front side of the vehicle body.

[0020] 6. The limiting plate fits the waterproof membrane on the fixed discharge rod. Under the restriction of the sliding block, the waterproof membrane cannot slide left and right, thereby ensuring the position of the waterproof membrane.

[0021] 7. The glue in the heated waterproof membrane has softened. When the rear pressure wheel presses over the waterproof membrane, the glue may stick to the rear pressure wheel. When the rear pressure wheel rotates, the scraper can scrape off the glue on the outside, thereby removing the glue adhering to the rear pressure wheel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] A TSR waterproofing membrane auxiliary laying device for underground engineering construction, such as Figure 1-12 As shown, it includes a vehicle body 1, a front wheel shaft 101, a fixed discharge rod 102, a guide wheel 103, a front pressure wheel 104, a rear wheel shaft 105, a rear pressure wheel 106, a handrail 107, a gas tank 2, an air guide pipe 2001, a placement rack 201, a rotating rod 202, a valve 2021, a fixed guide tube 206, a flame nozzle 210, a swing mechanism and an automatic fire-off mechanism. The front wheel shaft 101 is provided between the rotating wheels on the front side of the vehicle body 1, and the rotating wheels on the rear side of the vehicle body 1 are provided between the rotating wheels on the rear side of the vehicle body 1. A rear wheel shaft 105 is arranged between the vehicle body 1. When the vehicle body 1 moves, the front wheel shaft 101 and the rear wheel shaft 105 will rotate accordingly. A fixed discharge rod 102 is fixed on the front side of the vehicle body 1. The fixed discharge rod 102 is used to place the waterproof coiled material. A guide wheel 103, a front pressing wheel 104 and a rear pressing wheel 106 are arranged in the vehicle body 1. After the waterproof coiled material passes through the guide wheel 103, it is pressed on the paving surface by the front pressing wheel 104. A handrail 107 is also fixed on the vehicle body 1. The staff can use the handrail to lay the waterproof coiled material. The hand 107 pushes the vehicle body 1 to move, and a placement rack 201 is provided in the middle section of the vehicle body 1. A gas cylinder 2 is installed on the placement rack 201, and a fixed conduit 206 is connected to the gas cylinder 2 through an air pipe 2001. The gas in the gas cylinder 2 enters the fixed conduit 206 through the air pipe 2001, and the fixed conduit 206 is fixedly arranged on the placement rack 201. A rotating rod 202 is rotatably arranged in the placement rack 201, and the rotating rod 202 passes through the air pipe 2001. The part of the rotating rod 202 located on the inner side of the air pipe 2001 is connected to the valve 2021, and the rotating rod 202 can drive the valve 2021 to rotate when it rotates. The fixed conduit 206 is connected to a flamethrower 210 through a hose, and a swing mechanism is provided on the placement rack 201, and the swing mechanism is used to drive the flamethrower 210 to swing. The automatic fire-off mechanism is provided on the placement rack 201, and the automatic fire-off mechanism is used to drive the valve 2021 to rotate to block the air pipe 2001 and stop supplying gas to the flamethrower 210.

[0038] Before laying, the waterproofing coiled material is first placed outside the fixed discharge rod 102, and then the front end of the waterproofing coiled material is wound backward from the middle of the two guide wheels 103, and then placed at the bottom of the front pressure wheel 104, and then the rotating rod 202 is manually rotated. After the rotating rod 202 opens the valve 2021 in the air guide pipe 2001, the gas in the gas tank 2 is ejected from the flame vent 210 through the air guide pipe 2001 and the fixed guide tube 206, and the gas is ignited at the flame vent 210, and then the vehicle body 1 is manually pushed to move. When the vehicle body 1 moves, the front pressure wheel 104 will press the waterproofing coiled material and roll forward, so that the waterproofing coiled material is on the fixed discharge rod 10 2, when the waterproof coiled material passes through the flame vents 210, the glue on the waterproof coiled material is heated and melted, so that the waterproof coiled material sticks to the ground. As the vehicle body 1 moves, the waterproof coiled material in the heating pot will be crushed by the rear pressure wheel 106, and the waterproof coiled material will be pressed tightly on the ground. During the movement of the vehicle body 1, the swing mechanism will run accordingly, and the swing mechanism will drive the two flame vents 210 to swing back and forth, so that the waterproof coiled material can be heated evenly. When laying is completed, the automatic fire-off mechanism will automatically rotate the rotating rod 202 and close the valve 221, and the flame vents 210 will stop spraying fire, realizing the function of automatic heating and laying of waterproof coiled material.

[0039] like Figure 3-5 As shown, the swing mechanism includes a first pulley 203, a transmission belt 204, a second pulley 205, a fixed slide rail 207, a rotating guide column 208, a sliding ball 209 and a sliding connecting rod 2091. The first pulley 203 is fixed on the rear wheel shaft 105, and the second pulley 205 is rotatably provided on the placement frame 201. The transmission belt 204 is wound between the first pulley 203 and the second pulley 205. The diameter of the first pulley 203 is larger than that of the second pulley 205. The fixed guide 206 is fixed with a fixed slide rail 207, the second pulley 205 is coaxially fixedly connected with a rotating guide column 208, a wavy slide groove is provided on the rotating guide column 208, a sliding ball 209 is slidably provided in the slide groove on the rotating guide column 208, the sliding ball 209 can slide in the slide groove on the rotating guide column 208, the sliding ball 209 is slidably connected to the fixed slide rail 207 through a sliding connecting rod 2091, the sliding ball 209 is also fixedly connected to the flame-spouting port 210 through a connecting rod, and when the rotating guide column 208 rotates, the sliding ball 209 can make the flame-spouting port 210 swing left and right.

[0040] When the vehicle body 1 moves, the rear wheel shaft 105 will drive the transmission belt 204 and the second pulley 205 to rotate through the first pulley 203. When the second pulley 205 rotates, it can drive the fixed slide rails 207 on both sides thereof to rotate. The fixed slide rails 207 are provided with wavy slide grooves. When the fixed slide rails 207 rotate, the sliding ball 209 in the slide groove will drive the sliding connecting rod 2091 to slide back and forth in the fixed slide rail 207. When the sliding ball 209 slides along the slide groove, it can also drive the flamethrower 210 to swing left and right, so that the flamethrower 210 can evenly heat the waterproof membrane, thereby realizing the function of driving the flamethrower 210 to move back and forth.

[0041] like Figure 6 As shown, the automatic fire-off mechanism includes a cam 3, a lifting frame 301, a fixed guide sleeve 302, a connecting spring 303, a fixed slide 304, a sliding frame 305, a return spring 306, a swing block 307 and a torsion spring 308. The second pulley 205 is coaxially fixedly connected with the cam 3. The placement frame 201 is fixedly provided with a fixed guide sleeve 302. The lifting frame 301 is slidably provided in the fixed guide sleeve 302. The cam 3 can prop up the lifting frame 301. A connecting spring 303 is provided between the lifting frame 301 and the placement frame 201. The two ends of the connecting spring 303 are respectively fixed on the lifting frame 301 and the placement frame 201. The lifting frame 301 is provided with a fixed A slideway 304 and a sliding frame 305 are provided in the fixed slideway 304 for sliding movement. A return spring 306 is provided between the sliding frame 305 and the fixed slideway 304. The two sliding frames 305 are symmetrically arranged. The two ends of the return spring 306 are respectively fixed on the sliding frame 305 and the fixed slideway 304. A torsion spring 308 is provided between the rotating rod 202 and the air guide tube 2001. The two ends of the torsion spring 308 are respectively fixed on the air guide tube 2001 and the rotating rod 202. A swing block 307 is also fixed on the rotating rod 202. When the rotating rod 202 rotates, the swing block 307 rotates accordingly. The two sliding frames 305 can support the swing block 307 from the bottom of the swing block 307.

[0042] When laying the waterproof membrane, the cam 3 in the vehicle body 1 first pushes the lifting frame 301 upward, at this time the connecting spring 303 is stretched, and then the rotating rod 202 is rotated. The rotating rod 202 will drive the swing block 307 to swing upward during rotation. The upward swing of the swing rod will push the two sliding frames 305 to both sides and stretch the return spring 306. When the swing rod rotates to a horizontal state, the swing rod just breaks contact with the two sliding frames 305. The two sliding frames 305 will slide inward under the elastic force of the return spring 306 and support the swing rod from the bottom. At this time, the valve 2021 has just been opened, and the swing rod cannot swing downward under the support of the two sliding frames 305, and the torsion spring 308 is also restricted. During the movement of the vehicle body 1, the cam 3 continues to rotate with the second pulley 205. Due to the first pulley 203 The diameter of the cam 3 is larger than that of the second pulley 205, so the second pulley 205 rotates faster, and the time for the cam 3 to rotate one circle is much shorter than the time for the lifting frame 301 to be pulled down by the connecting spring 303. Therefore, when the lifting frame 301 descends and contacts with the sliding frame 305, the cam 3 can prop up the lifting frame 301 again, making it difficult for the lifting frame 301 to open the sliding frame 305 during the movement of the vehicle body 1. When the vehicle body 1 stops moving, the protruding part of the cam 3 faces downward. At this time, the lifting frame 301 will slide downward under the pull of the connecting spring 303 and open the two sliding frames 305 outward, and the swing blocks 307 and the rotating rod 202 on the inner sides of the two sliding frames 305 will swing downward and reset under the action of the torsion spring 308, and at the same time close the valve 2021, thereby realizing the function of automatically closing the valve 2021.

[0043] like Figure 6-7 As shown, it also includes a slow-stop mechanism, which is used to slow down the closing speed of the automatic flame-off mechanism when laying is completed, so that the last laid coil receives enough heat.

[0044] If the flame nozzle 210 is closed immediately when the vehicle body 1 stops being pushed, the last section of waterproof coiled material laid will be heated for too short a time, which may cause the waterproof coiled material to not be firmly bonded to the ground. The stop-change mechanism can provide a resistance to the lifting frame 301 when it descends, preventing the lifting frame 301 from descending too quickly, thereby achieving the function of heating the last laid coiled material.

[0045] like Figure 6-7As shown, the slow stop mechanism includes a vertical slide 4, a connecting rod 401, a sliding rod 402, a ratchet bar 403, a ratchet 404 and a U-shaped fixed rod 405. The vertical slide 4 is fixedly provided on the placement rack 201, and a sliding rod 402 is slidably provided in the vertical slide 4. The sliding rod 402 is connected to the lifting rack 301 through the connecting rod 401. The sliding rod 402 and the connecting rod 401 will move up and down with the lifting rack 301. A ratchet bar 403 is provided on the sliding rod 402, and a U-shaped fixed rod 405 is fixed on the placement rack 201. The U-shaped fixed rod 405 is damped and connected with a ratchet 404. The ratchet 404 will encounter a certain resistance when rotating on the U-shaped fixed rod 405, and the ratchet bar 403 is meshed with the ratchet 404, and the ratchet 404 will prevent the ratchet bar 403 from descending.

[0046] When the vehicle body 1 stops moving, the connecting spring 303 will pull the lifting frame 301 downward, and the lifting frame 301 will drive the sliding rod 402 to slide downward through the connecting rod 401 at its rear side. When the sliding rod 402 slides downward, it will drive the ratchet bar 403 to move downward, and the ratchet bar 403 will mesh with the ratchet wheel 404 when it moves downward. Since the ratchet wheel 404 and the U-shaped fixing rod 405 are connected by damping, the ratchet wheel 404 will prevent the ratchet bar 403 from descending. The descending speed of the ratchet bar 403 will be affected by the ratchet wheel 404, and the descending speed of the sliding rod 402 and the lifting frame 301 will also be affected by the ratchet wheel 404. Therefore, when the vehicle body 1 stops moving, the lifting frame 301 is affected by the ratchet wheel 404 and slides slowly downward. During the descent of the lifting frame 301, the flame nozzle 210 will heat the waterproof membrane laid last to enhance the bonding effect of the waterproof membrane and the ground.

[0047] like Figure 1 and Figure 8 As shown, a cleaning mechanism is also included, which includes a collecting brush 5, an arc-shaped baffle 501, a first fixed frame 502, a collecting frame 503, an exhaust fan 504 and a filter cloth 505. The collecting brush 5 is evenly distributed on the front wheel shaft 101 of the vehicle, and the collecting brush 5 can contact the ground. The first fixed frame 502 is fixed in the vehicle body 1, and the collecting brush 5 will sweep the debris on the ground into the first fixed frame 502. The arc-shaped baffle 501 is fixed on the first fixed frame 502, and the arc-shaped baffle 501 can prevent the debris stuck in the collecting brush 5 from flying backward from the upper side of the vehicle body 1. The first fixed frame 502 is provided with a collecting frame 503 and an exhaust fan 504, and the collecting frame 503 is installed with a filter cloth 505.

[0048] When laying the waterproof membrane, there may be stones and other debris on the ground. When the vehicle body 1 moves, turn on the exhaust fan 504, and the collecting brush 5 set on the front wheel shaft 101 of the vehicle will sweep the stones on the ground backwards into the first fixed frame 502, and the filter cloth 505 will filter the debris to prevent the stones from passing through the rear side of the collecting frame 503 in the first fixed frame 502. After laying, the collecting frame 503 in the first fixed frame 502 is pulled outward, and then the stones and other debris in the collecting frame 503 are poured out, thereby realizing the function of cleaning the debris on the front side of the vehicle body 1.

[0049] like Figure 2 and Figure 9-10 As shown, a limiting mechanism is also included, which is installed on the fixed unwinding rod 102 and is used to clamp the coil.

[0050] During the movement of the vehicle body 1, the waterproof coiled material fixed on the discharge rod 102 will rotate continuously. During the rotation of the waterproof coiled material, the limiting mechanism can limit the left and right sliding of the waterproof coiled material to ensure the laying effect.

[0051] like Figure 2 and Figure 9-10 As shown, the limiting mechanism includes a limiting plate 6, an arc guide plate 601, a fixing frame 602, a pulling block 603, a sliding block 604, a reset spring 605 and a pull rope 606. The vehicle body 1 is fixed with an arc guide plate 601, and the fixed discharge rod 102 is just located at the center of the arc guide plate 601. When placing the waterproof coiled material, the arc guide plate 601 plays a supporting and guiding role. The fixed discharge rod 102 is fixed with a fixing frame 602. The fixed discharge rod 102 is slidably provided with a limiting plate 6. The limiting plate 6 is tightly attached to one end of the waterproof coiled material, and the fixing A sliding stopper 604 is provided on the discharge rod 102 for sliding movement. When the sliding stopper 604 extends outward, it can prevent the limit plate 6 from moving. A return spring 605 is provided between the sliding stopper 604 and the fixed discharge rod 102. The two ends of the return spring 605 are respectively fixed on the fixed discharge rod 102 and the sliding stopper 604. A pull rope 606 is fixed on the sliding stopper 604. The pull rope 606 passes through the fixed frame 602 and is fixed on the pulling block 603. Manual movement of the pulling block 603 can drive the sliding stopper 604 to move through the pull rope 606.

[0052] When placing the waterproof coiled material into the fixed discharge rod 102, the end of the waterproof coiled material is placed on the arc guide plate 601 and the gap in the middle of the waterproof coiled material is aligned with the fixed discharge rod 102, and then the waterproof coiled material is pushed to move toward the fixed discharge rod 102. When the waterproof coiled material contacts the sliding stopper 604 on the fixed discharge rod 102, it can squeeze the inner shape and compress the return spring 605. When the waterproof coiled material is out of contact with the sliding stopper 604, the sliding stopper 604 will slide outward under the push of the return spring 605. When the waterproof coiled material is placed, First, place the limiting plate 6 in the arc guide plate 601, and then pull the pulling block 603 outward so that the pulling block 603 passes through the center of the limiting plate 6. When the pulling block 603 is pulled outward, the pull rope 606 will pull the sliding block 604 inward. When the sliding block 604 retracts into the fixed discharge rod 102, the limiting plate 6 is pushed to make it close to the waterproof membrane. Then, release the pulling block 603, and the sliding block 604 will slide outward under the elastic force of its respective return springs 605 and block the outside of the limiting plate 6, thereby realizing the function of limiting the waterproof membrane.

[0053] like Figure 11-12 As shown, it also includes a scraper 7, a second fixed frame 701, a rotating shaft 702, a spiral spring 703, a rotating plate 704 and a glue collecting frame 705. The scraper 7 and the second fixed frame 701 are fixed in the vehicle body 1. The scraper 7 is tangent to the rear pressure wheel 106. The second fixed frame 701 is rotatably connected with a rotating plate 704 through the rotating shaft 702. There is a gap between the rotating plate 704 and the rear pressure wheel 106. A spiral spring 703 is connected between the rotating shaft 702 and the second fixed frame 701. Both ends of the spiral spring 703 are respectively fixed on the rotating shaft 702 and the second fixed frame 701. A glue collecting frame 705 is provided in the second fixed frame 701. The glue collecting frame 705 is used to collect the glue scraped by the scraper 7. The glue collecting frame 705 is magnetically connected to the second fixed frame 701, and the glue collecting frame 705 can be drawn out from the second fixed frame 701.

[0054] The glue on the heated waterproof coiled material melts. When the rear pressure wheel 106 passes through the waterproof coiled material, the glue on the waterproof coiled material may stick to the rear pressure wheel 106. The glue on the rear pressure wheel 106 will be scraped off when passing through the scraper 7, and the glue on the scraper 7 will flow along the rotating plate 704 into the glue collecting frame 705 in the second fixed frame 701. If the glue on the rear pressure wheel 106 is thicker, the rotating plate 704 will rotate around the rotating shaft 702 toward the inside of the second fixed frame 701. When the thicker part is out of contact with the rotating plate 704, the rotating plate 704 will rotate and reset along with the rotating shaft 702 under the elastic force of the spiral spring 703, thereby achieving the function of scraping off the glue adhering to the rear pressure wheel 106.
