Description

Technical Field

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

[0002] In the construction of rail transit, in order to enhance the waterproof performance of the tunnel structure, pre-laid waterproof membrane is used to lay on the surface of the tunnel structure. The existing technology uses manual laying method to lay the waterproof membrane on the tunnel structure, which makes it difficult to uniformly preheat the surface of the waterproof membrane. If the temperature is too low, the adhesion between the waterproof membrane and the base layer will be poor, and if the temperature is too high, the membrane will easily melt through.

[0003] Furthermore, during the manual pre-laying of waterproof membrane, small pebbles adhere to the surface of the tunnel structure base. When the waterproof membrane is laid on the tunnel structure base, these pebbles push up the corresponding waterproof membrane, creating gaps between the waterproof membrane and the tunnel structure base, resulting in bulges. Even with significant pressure applied to these gaps, the interference from the pebbles themselves cannot eliminate the bulges between the waterproof membrane and the tunnel structure base. This affects the full adhesion between the waterproof membrane and the tunnel structure base, making it easy for the waterproof membrane to detach from the tunnel structure base, greatly reducing the waterproof performance of the tunnel structure base.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a pre-laid waterproof membrane laying device to solve the problems mentioned in the background art, such as the difficulty in uniformly preheating the surface of the waterproof membrane and removing small stones adhering to the tunnel structure base surface when the existing waterproof membrane is laid manually, which causes bulges between the waterproof membrane and the tunnel structure base surface and affects the waterproof performance of the tunnel structure base surface.

[0050] Furthermore, the blowing area of ​​the blowing assembly is isolated from the pre-laying area of ​​the waterproof membrane using a mounting bracket and a guide plate.

[0051] Compared with the prior art, the beneficial effects of the present invention are:

[0052] 1. This invention, by setting up a preheating component and a driving component, allows the upper and lower spray pipes to spray the tunnel structure base surface. During the spraying process, the driving motor drives the cam to rotate via the drive shaft. The cam drives the first rack rod to move along the first guide rail via the push rod. The first rack rod drives the upper spray pipe to move via the upper swing rod. At the same time, the first rack rod drives the second rack rod to move along the second guide rail in the opposite direction to the first rack rod via the reversing gear. The second rack rod drives the guide rod to move along the retraction groove, which compresses the pre-tension spring. Simultaneously, the second rack rod drives the lower spray pipe to move via the lower swing rod. Under the reciprocating push of the cam on the push rod and the continuous elastic force of the pre-tension spring on the second rack rod, the upper and lower spray pipes swing and spray heat along the continuously fed waterproof membrane, ensuring that the surface of the waterproof membrane can be uniformly preheated and improving the subsequent pre-laying and bonding effect.

[0053] 2. In this invention, during the process of moving the support by pulling the plate, the support moves the guide plate through the mounting frame. The guide plate moves the inclined slope along the upper surface of the tunnel structure base. When there are stones on the upper surface of the tunnel structure base, the inclined slope can directly scoop the stones onto the guide plate, thereby avoiding the stones from hindering the pre-laying process when pre-laying waterproof membrane.

[0054] 3. In this invention, the drive shaft drives the second belt to rotate, the second belt drives the second helical gear to rotate via the driven shaft, the second helical gear drives the rotating shaft to rotate via the first helical gear, the rotating shaft drives the first belt to rotate via the driven roller, and the first belt drives the push rod to move along the upper surface of the guide plate, so that the stones shoveled onto the guide plate by the inclined slope are carried out into the collection trough for collection, thereby achieving the timely transfer of stones from the guide plate and avoiding the subsequent impact of the inclined slope's shoveling effect due to the accumulation of stones on the guide plate.

[0055] 4. This invention improves the waterproofing performance of the tunnel structure by activating a blower during the process of shoveling stones on an inclined slope. The blower continuously blows air through the air outlet to the transition area between the inclined slope and the tunnel structure base surface, causing dust that is difficult to shovel away from the pre-laid area. This avoids dust interference between the waterproof membrane and the tunnel structure base surface, which could lead to bulging between the waterproof membrane and the tunnel structure base surface.

[0056] 5. By isolating the blowing area of ​​the blower assembly from the pre-laying area of ​​the waterproof membrane using a mounting frame and a guide plate, the present invention can ensure that when the blower blows away the dust on one side of the mounting frame and guide plate, the preheated waterproof membrane on the other side of the mounting frame and guide plate will not be stuck to the dust.

Detailed Implementation

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] Example 1

[0067] Please see Figure 1-7 The present invention provides a technical solution:

[0068] A pre-laid waterproof membrane laying device includes a tunnel structure base surface 100, and further includes:

[0069] The laying unit 1 is located on the upper end of the tunnel structure base surface 100 and is used to move along the surface of the tunnel structure base surface 100 to complete the laying of the waterproof membrane 131.

[0070] The preheating unit 2 includes a preheating component 21 disposed at the upper end of the laying unit 1 for heating the surface of the waterproof membrane 131 and a driving component 22 disposed on one side of the preheating component 21 for driving the preheating component 21 to reciprocate.

[0071] The cleaning unit 3 includes a shovel assembly 31 located near the surface of the tunnel structure base 100 for shoveling up stones from the tunnel entrance surface, and an outlet assembly 32 located at the upper end of the shovel assembly 31 for exporting and collecting the shoveled stones.

[0072] It should be noted that during use, the laying unit 1 is pulled to move along the upper surface of the tunnel structure base 100. The laying unit 1 lays the waterproof membrane 131 along the upper end of the tunnel structure base 100 after passing through the preheating component 21. When the waterproof membrane 131 passes through the preheating component 21, the drive component 22 drives the preheating component 21 to swing back and forth, so that the waterproof membrane 131 can be preheated evenly before pre-laying. At the same time, the laying unit 1 drives the shovel component 31 to shovel up the stones on the tunnel structure base 100. The drive component 22 drives the guide component 32 to rotate, so that the stones shoveled on the shovel component 31 can be carried out in time. This ensures that the surface of the waterproof membrane 131 is evenly preheated, and also cleans up the stones in the pre-laying area in time, avoiding bulging between the waterproof membrane 131 and the tunnel structure base 100.

[0073] As an improvement, the laying unit 1 includes:

[0074] Bracket 11;

[0075] A pressure roller 12, located at the lower end of the support 11, is used to roll along the surface of the tunnel structure base 100 to lay the waterproof membrane 131.

[0076] Roller 13, mounted on the upper end of the bracket 11, is used to unwind the waterproof membrane 131;

[0077] Guide roller 14, connected to the upper end of the bracket 11 near the preheating assembly 21, is used to flatten and guide the waterproof membrane 131.

[0078] Furthermore, the preheating component 21 includes:

[0079] A cantilever beam 211 is connected to the upper end of the bracket 11. A first guide rail 2111 is provided inside the upper part of the cantilever beam 211, and a second guide rail 2113 is provided inside the lower part of the cantilever beam 211. An installation groove 2112 is provided inside the cantilever beam 211 and between the first guide rail 2111 and the second guide rail 2113. A retraction groove 2114 is provided inside the cantilever beam 211 and at one end of the second guide rail 2113.

[0080] The first rack rod 212 is slidably inserted into the first guide rail 2111. One end of the rack rod 2121 is fixedly connected to a push rod 2121 extending from the inside of the first guide rail 2111 to the outside. An upper swing rod 2122 is connected to one side of the first rack rod 2122. Multiple sets of upper spray pipes 2123 are provided at equal intervals on one side of the upper swing rod 2122.

[0081] The second rack rod 215 is slidably inserted into the second guide rail 2113. A lower swing rod 2151 is connected to one side of the second rack rod 215. A lower spray pipe 2152 is provided at equal intervals on one side of the lower swing rod 2151. The lower spray pipe 2152 and the upper spray pipe 2123 are staggered.

[0082] It should be added that the upper spray pipe 2123 and the lower spray pipe 2152 are equipped with temperature control monitoring devices, which are not shown in the figure. These devices are used to monitor the spray temperature of the upper spray pipe 2123 and the lower spray pipe 2152 in real time, so as to prevent the waterproof membrane 131 from being poorly bonded to the base layer due to excessively low temperature, and the waterproof membrane 131 from being easily melted through due to excessively high temperature.

[0083] The limiting shaft 213 is fixedly inserted into the mounting groove 2112;

[0084] The reversing gear 214 is rotatably connected to the outside of the limiting shaft 213. Its upper end and lower end are respectively engaged with the first rack 212 and the second rack 215, and are used to switch the movement direction of the first rack 212 and the second rack 215.

[0085] The guide rod 216 is slidably inserted into the retraction groove 2114 and one end is connected to the second rack rod 215;

[0086] A preload spring 217 is sleeved on the outside of the guide rod 216 and is used to drive the second rack rod 215 to reset.

[0087] Furthermore, the driving component 22 includes:

[0088] Mounting plate 221 is connected to one side of the bracket 11;

[0089] A drive motor 222 is connected to the lower end of the mounting plate 221, and a drive shaft 2221 is provided on the upper end of the drive motor 222.

[0090] Cam 223, connected to the upper end of drive shaft 2221, is used to drive push rod 2121 to swing back and forth.

[0091] The preheating unit 2 further includes a heating component 23, which includes:

[0092] Heating tank 231 is placed on the upper end of the support 11;

[0093] A conduit 232 is connected to the upper end of the heating tank 231, and a valve 2321 for controlling the heating supply of the heating tank 231 is provided at the upper end of the conduit 232.

[0094] The upper end of the hose 233 is connected to one end of the conduit 232, and the lower end is connected to the interior of the preheating component 21.

[0095] As an improvement, the shovel assembly 31 includes:

[0096] The guide plate 311 is connected to the output component 32;

[0097] An inclined slope 313 is connected to one side of the guide plate 311. It extends obliquely from the upper surface of the guide plate 311 to a position close to the upper surface of the tunnel structure base surface 100, and is used to shovel stones on the tunnel structure base surface 100 into the upper surface of the guide plate 311.

[0098] A collection trough 312 is located at one end of the guide plate 311 and is used to collect the stones brought out by the discharge component 32 from the guide plate 311.

[0099] Furthermore, the export component 32 includes:

[0100] Mounting bracket 321 is connected to the lower end of the preheating component 21;

[0101] The rotating shaft 322 is rotatably inserted into the mounting bracket 321 and is located directly above the collection groove 312;

[0102] The driven roller 323 is fixedly sleeved on the outside of the rotating shaft 322;

[0103] The first belt 324 is sleeved on the outside of the driven roller 323;

[0104] Multiple sets of push rods 325 are provided at equal intervals along one side of the inclined slope 313 along the first belt 324, and are used to push the stones on the guide plate 311 into the collection trough 312.

[0105] Furthermore, the export component 32 also includes:

[0106] The first helical gear 326 is fixedly connected to one end of the rotating shaft and is used to drive the rotating shaft 322 to rotate.

[0107] The second helical gear 327 meshes with the upper end of the first helical gear 326;

[0108] Driven shaft 328 is connected to the upper end of the second helical gear 327;

[0109] The second belt 329 has one end sleeved on the outside of the driven shaft 328 and the other end sleeved with the drive assembly 22.

[0110] The cleaning unit 3 further includes a blower assembly 33, which includes:

[0111] Hair dryer 331 is connected to one side of the mounting bracket 321;

[0112] Air outlet 332 is connected to one side of the blower 331. The air outlet 332 is tilted and aligned with the transition area between the inclined slope 313 and the tunnel structure base surface 100. It is used to blow dust that is difficult to be scooped up by the inclined slope 313 to areas outside the pre-laid waterproof membrane 131.

[0113] It should be noted that during use, the laying unit 1 is placed on the upper surface of the tunnel structure base 100, and the waterproof membrane 131 is pre-pulled from the roller 13 through the guide roller 14 to the bottom of the pressure roller 12. Then, the drive motor 222 is started and the valve 2321 is opened, so that the heat source in the heating tank 231 enters the upper swing rod 2122 and the lower swing rod 2151 through the conduit 232 and the hose 233 respectively. The upper swing rod 2122 sprays hot air onto the surface of the waterproof membrane 131 through the upper spray pipe 2123, and the lower swing rod 2151 sprays hot air onto the surface of the waterproof membrane 131 through the lower spray pipe 2152, so that the surface of the waterproof membrane 131 is preheated. Then, the pulling plate 111 is pulled, and the pulling plate 111 drives the pressure roller 12 to roll along the upper surface of the tunnel structure base 100 through the bracket 11, so that the waterproof membrane 131 is pre-laid by the pressure roller 12 along the upper surface of the tunnel structure base 100.

[0114] like Figure 2-5 As shown, this invention, by setting a preheating component 21 and a driving component 22, during the spraying process of the upper nozzle 2123 and the lower nozzle 2152 onto the tunnel structure base surface 100, the driving motor 222 drives the cam 223 to rotate via the driving shaft 2221. The cam 223 drives the first rack rod 212 to move along the first guide rail 2111 via the push rod 2121. The first rack rod 212 drives the upper nozzle 2123 to move via the upper swing rod 2122. At the same time, the first rack rod 212 drives the second rack rod 215 along the second guide rail 2113 towards the first rack rod 2123 via the reversing gear 214. 12. Moving in the opposite direction, the second rack rod 215 drives the guide rod 216 to move along the retraction groove 2114, which compresses the pre-tension spring 217. At the same time, the second rack rod 215 drives the lower spray pipe 2152 to move through the lower swing rod 2151. Under the reciprocating push of the cam 223 on the push rod 2121 and the continuous elastic force of the pre-tension spring 217 on the second rack rod 215, the upper spray pipe 2123 and the lower spray pipe 2152 swing and spray heat along the continuously fed waterproof membrane 131 to ensure that the surface of the waterproof membrane 131 can be preheated evenly and improve the subsequent pre-laying bonding effect.

[0115] like Figure 6-7 As shown, in order to prevent the waterproof membrane 131 from not being able to fully contact the tunnel structure base surface 100 due to the presence of stones on the surface of the tunnel structure base surface 100 before the pressure roller 12 pre-lays the waterproof membrane 131, this invention, in the process of the pull plate 111 pulling the support 11 to move, the support 11 drives the guide plate 311 to move through the mounting frame 321. The guide plate 311 drives the inclined slope 313 to move along the upper surface of the tunnel structure base surface 100. When there are stones on the upper surface of the tunnel structure base surface 100, the inclined slope 313 can directly scoop the stones onto the guide plate 311, thereby avoiding the stones from hindering the pre-laying process when pre-laying the waterproof membrane 131.

[0116] While the drive motor 222 drives the cam 223 to rotate via the drive shaft 2221, it also drives the second belt 329 to rotate via the drive shaft 2221. The second belt 329 drives the second helical gear 327 to rotate via the driven shaft 328. The second helical gear 327 drives the rotating shaft 322 to rotate via the first helical gear 326. The rotating shaft 322 drives the first belt 324 to rotate via the driven roller 323. The first belt 324 drives the push rod 325 to move along the upper surface of the guide plate 311, so that the stones shoveled onto the guide plate 311 by the inclined slope 313 are carried out into the collection trough 312 for collection. This achieves the timely transfer of stones from the guide plate 311, preventing the subsequent accumulation of stones on the guide plate 311 from affecting the shoveling effect of the inclined slope 313.

[0117] In addition, such as Figure 6 As shown, in the implementation of this invention, for some dust that is difficult to be scooped up by the inclined slope 313, the present invention activates the blower 331 during the process of scooping stones on the inclined slope 313. The blower 331 continuously blows air through the air outlet 332 to the transition area between the inclined slope 313 and the tunnel structure base surface 100, so that the dust that is difficult to be scooped up is blown away from the pre-laid area, avoiding the interference of dust between the waterproof membrane 131 and the tunnel structure base surface 100, which would cause bulging between the waterproof membrane 131 and the tunnel structure base surface 100, thereby improving the waterproof performance of the tunnel structure base surface 100.

[0118] Example 2

[0119] like Figure 6 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0120] The blowing area of ​​the blowing assembly 33 is isolated from the pre-laying area of ​​the waterproof membrane 131 by the mounting bracket 321 and the guide plate 311.

[0121] This design ensures that when the blower 331 blows away dust from one side of the mounting bracket 321 and the guide plate 311, the preheated waterproof roll 131 on the other side of the mounting bracket 321 and the guide plate 311 will not be stuck to the dust.

[0122] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0123] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
