Abstract

This invention relates to the field of waterproof membrane laying, and more particularly to a device for laying waterproof membranes in civil engineering. Current methods for laying waterproof membranes often result in uneven laying and gaps at the overlap of two membranes. This device for laying waterproof membranes in civil engineering includes a grooved support plate, etc. A connecting rod is fixedly connected to the upper part of the grooved support plate, and two support frames are fixedly connected to the connecting rod, with the two support frames arranged symmetrically. When the operator starts a servo motor, the device moves forward, unwinding the asphalt felt onto the ground. One end of the asphalt felt covers the already laid asphalt felt on the ground, while a pressure roller presses the newly laid asphalt felt and the overlap between the two felts. This results in a smoother laying of the asphalt felt and a tighter fit between the two felts, leading to better waterproofing after the asphalt felt is laid.

Description

Technical Field

[0001] This invention relates to the field of waterproof membrane laying, and more particularly to a waterproof membrane laying device for civil engineering. Background Technology

[0002] Waterproof membrane, also known as asphalt felt, has excellent waterproof and flexible properties. It is mainly used in building walls, roofs, etc., to resist the seepage of external rainwater and groundwater. It is a flexible building material that can be rolled up and serves as a leak-proof connection between the foundation of the project and the building. It is the first barrier for waterproofing the entire project and plays a vital role in the overall project.

[0003] However, the current process of laying waterproof membrane usually involves multiple workers working together, which requires high skill levels from the workers. This can easily lead to the waterproof membrane not being laid evenly. In order to achieve a good waterproof effect, the joints of two adjacent waterproof membranes need to overlap, but there will be gaps at the overlaps, which will result in the two waterproof membranes not being bonded tightly enough, thus affecting the waterproof effect of the asphalt felt. Summary of the Invention

[0004] In view of the shortcomings or deficiencies of the prior art, the present invention provides a civil engineering waterproof membrane laying device, which can make the asphalt felt laid more flat and reduce the gap between two asphalt felts, so that the two asphalt felts are more tightly bonded, thereby making the waterproof effect of the asphalt felt better.

[0005] A waterproof membrane laying device for civil engineering includes a slotted support plate, a connecting rod fixedly connected to the upper part of the slotted support plate, two support frames fixedly connected to the connecting rod, the two support frames being symmetrically arranged, a support roller being rotatably connected between the upper parts of the two support frames, an intermittent moving mechanism being provided on the support frame, the intermittent moving mechanism being used to drive the device to move intermittently, the intermittent moving mechanism being connected to the slotted support plate, and a flattening mechanism being provided on the support frame, the flattening mechanism being used to flatten the asphalt felt.

[0006] As a preferred embodiment of the present invention, the top of the slotted support plate has a placement slot.

[0007] As a preferred embodiment of the present invention, the top of the connecting rod has a second placement groove.

[0008] As a preferred embodiment of the present invention, the intermittent moving mechanism includes rotating rollers. Three rotating rollers are rotatably connected between the two support frames. Two of the rotating rollers have a first auxiliary wheel fixedly connected to their ends away from the slotted support plate, and the other rotating roller has a first traveling wheel fixedly connected to its end away from the slotted support plate. Three lifting blocks are slidably connected to the slotted support plate. Two of the lifting blocks have two second auxiliary wheels, and the other lifting block has a second traveling wheel. Compression springs connect the slotted support plate and the three lifting blocks. Two rotating rollers are rotatably connected to the two second auxiliary wheels via universal couplings, and the other rotating roller is connected to the second traveling wheel via a universal coupling. A servo motor is fixedly connected to the connecting rod. A power shaft is fixedly connected to the output shaft of the servo motor. The power shaft is rotatably connected to one of the support frames. A small sector gear is fixedly connected to the power shaft, and a large gear is fixedly connected to the other rotating roller. The large gear is located below the small sector gear and meshes with it.

[0009] As a preferred embodiment of the present invention, the flattening mechanism includes a lifting support rod, which is slidably connected to two support frames. A compression spring is connected between the lifting support rod and the support frame, and the compression spring is sleeved on the lifting support rod. A pressure roller is rotatably connected between the lower parts of the two lifting support rods.

[0010] As a preferred embodiment of the present invention, it further includes a bubble leveling mechanism, which is mounted on another rotating roller. The bubble leveling mechanism includes a large sector gear, which is fixedly connected to a power shaft. A bidirectional screw is rotatably connected between the connecting rod and one of the support frames. A small gear is fixedly connected to the bidirectional screw, which is located above the large sector gear and meshes with it. A movable support is threaded onto the bidirectional screw. The power shaft passes through the movable support, and another rotating roller passes through the movable support. A fixed plate is fixedly connected to the lower part of the movable support. Two lifting rods are slidably connected to the fixed plate and are symmetrically arranged. Two return springs are connected between the fixed plate and each of the two lifting rods, and the return springs are sleeved on the lifting rods. Two leveling rollers are rotatably connected between the two lifting rods.

[0011] As a preferred embodiment of the present invention, it further includes a flattening and pressurizing mechanism, which is disposed on the connecting rod. The flattening and pressurizing mechanism includes a fixed rod, which is fixedly connected to the connecting rod. A slotted plate is fixedly connected to the bottom of the fixed rod, and a guide groove is formed on the slotted plate. A fixed round rod is fixedly connected between the tops of the two lifting rods, and the end of the fixed round rod away from the lifting rod is located in the guide groove on the slotted plate.

[0012] As a preferred embodiment of the present invention, it further includes a bonding rod, the bonding rod being fixedly connected between the lower parts of the two lifting rods, and a side scraper being fixedly connected between the bottoms of the two lifting rods.

[0013] The beneficial effects of this invention are as follows: First, the operator starts the servo motor, which drives the device forward. As the device moves forward, the asphalt felt is unrolled and laid on the ground. One end of the asphalt felt covers the asphalt felt already laid on the ground. At the same time, the pressure roller rolls the newly laid asphalt felt and the overlapping area of ​​the two asphalt felts. In this way, the purpose of laying asphalt felt on the ground can be achieved, and the asphalt felt laid on the ground can be rolled to make the asphalt felt laid flatter. At the same time, the overlapping area of ​​the two asphalt felts can be rolled to make the two asphalt felts fit more tightly, thereby making the waterproof effect of the laid asphalt felt better.

[0014] Secondly, when the output shaft of the servo motor drives the power shaft to rotate, one of the flattening rollers will reciprocate and press the overlapping part of the two asphalt felts, and the other flattening roller will reciprocate and press the asphalt felt laid on the ground, which can make the two asphalt felts fit together more tightly, thereby reducing the gap between the two asphalt felts.

[0015] In addition, when the fixed plate moves both lifting rods horizontally, the fixed round rod will move both lifting rods downward, and the two lifting rods will move the two flattening rollers downward. In this way, the roller pressure of the flattening rollers on the felt can be increased, which further makes the two felts fit together more tightly. Attached Figure Description

Detailed Implementation

[0024] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0025] Example 1: A device for laying waterproof membrane in civil engineering, such as Figures 1-6 As shown, the device includes a slotted support plate 1 with a placement slot 1 on its top. A connecting rod 2 is welded to the upper part of the slotted support plate 1, and a placement slot 2 is formed on the top of the connecting rod 2. Two support frames 3 are bolted to the connecting rod 2 and are symmetrically arranged. A support roller 31 is rotatably connected between the upper parts of the two support frames 3. An intermittent moving mechanism is provided on the support frame 3 to drive the device to move intermittently. The intermittent moving mechanism is connected to the slotted support plate 1. A flattening mechanism is provided on the support frame 3 to flatten the asphalt felt.

[0026] The intermittent moving mechanism includes rotating rollers 41. Three rotating rollers 41 are rotatably connected between the two support frames 3. Two of the rotating rollers 41, at their ends away from the slotted support plate 1, are connected to first auxiliary wheels 42 via flat keys. The other rotating roller 41, at its end away from the slotted support plate 1, is connected to a first traveling wheel 43 via a flat key. Three lifting blocks 44 are slidably connected to the slotted support plate 1. Two of the lifting blocks 44 have two second auxiliary wheels 45 mounted on them, and the other lifting block 44 has a second traveling wheel 46 mounted on it. Compression springs 47 are connected to the slotted support plate 1 and the three lifting blocks 44 via hooks. Two of the rotating rollers 41 are respectively connected to two of the second auxiliary wheels 42. A universal coupling 48 is rotatably connected between the two rollers 5 and the second traveling wheel 46. The universal coupling 48 is used to drive the second traveling wheel 46 and the two second auxiliary wheels 45. A servo motor 49 is bolted to the connecting rod 2. A power shaft 410 is welded to the output shaft of the servo motor 49. The power shaft 410 is rotatably connected to one of the support frames 3. A small sector gear 411 is connected to the power shaft 410 via a flat key. A large gear 412 is connected to the other roller 41 via a flat key. The large gear 412 is located below the small sector gear 411 and will mesh with the small sector gear 411.

[0027] The flattening mechanism includes a lifting support rod 51, which is slidably connected to two support frames 3. A compression spring 52 is connected between the lifting support rod 51 and the support frame 3 via a hook. The compression spring 52 is sleeved on the lifting support rod 51. A pressure roller 53 is rotatably connected between the lower parts of the two lifting support rods 51. The pressure roller 53 is used to roll the roofing felt.

[0028] Initially, an tarpaulin is laid on the ground. A roll of tarpaulin is placed between the top of the slotted support plate 1 and the top of the connecting rod 2. First, the worker pulls out one end of the tarpaulin, which passes over the support roller 31, two rotating rollers 41, and pressure roller 53, and is laid on the ground. Then, the worker starts the servo motor 49. The output shaft of the servo motor 49 drives the power shaft 410 to rotate. The rotation of the power shaft 410 drives the small sector gear 411 to rotate. The small sector gear 411 meshes with the large gear 412. The small sector gear 411 intermittently drives the large gear 412 to rotate. The rotation of the large gear 412 intermittently drives the other rotating roller 41 to rotate. The rotation of the rotating roller 41 intermittently drives the first traveling wheel 43 and one of the universal couplings 48 to rotate. The rotation of the universal coupling 48 intermittently drives the second traveling wheel 46 to rotate. The rotation of the first traveling wheel 43 and the second traveling wheel 46 together intermittently propels the device forward. The two first auxiliary wheels 42 and the two second auxiliary wheels 45 will intermittently rotate under the action of friction. The rotation of the first auxiliary wheels 42 and the second auxiliary wheels 45 will intermittently drive two of the rotating rollers 41 and the other two universal couplings 48 to rotate. As the device moves forward, the roofing felt will be unrolled and laid on the ground, with one end of the roofing felt covering the existing roofing felt on the ground. Simultaneously, the second traveling wheel 46 and the two second auxiliary wheels 45 roll onto the tarpaulin already laid on the ground. The tarpaulin on the ground compresses the second traveling wheel 46 and the two second auxiliary wheels 45, causing them to move upwards. The second traveling wheel 46 and the two second auxiliary wheels 45 then drive the three lifting blocks 44 to move upwards, compressing the compression spring 47. The second traveling wheel 46 and the two second auxiliary wheels 45 also drive the three universal couplings 48 to swing upwards. Then, the pressure roller 53 rolls the newly laid tarpaulin and the overlapping area of ​​the two tarpaulins. This process is repeated until the tarpaulin is laid and then disengages from the second traveling wheel 46 and the two second auxiliary wheels 45. The compression spring 47 will reset, which will cause the three lifting blocks 44 to move downwards and reset. The reset of the three lifting blocks 44 will cause the second traveling wheel 46 and the two second auxiliary wheels 45 to move downwards and reset respectively. The reset of the second traveling wheel 46 and the two second auxiliary wheels 45 will cause the three universal couplings 48 to swing downwards and reset respectively. Finally, the staff will turn off the servo motor 49. In this way, the purpose of laying asphalt felt on the ground can be achieved, and the asphalt felt laid on the ground can also be rolled to make the asphalt felt laid flatter. At the same time, the overlapping parts of two asphalt felts can also be rolled to make the two asphalt felts fit more tightly, thereby making the waterproof effect of the laid asphalt felt better.

[0029] Example 2: Based on Example 1, such as Figure 5 and Figure 6As shown, it also includes a bubble leveling mechanism, which is mounted on the power shaft 410. The bubble leveling mechanism includes a large sector gear 61, which is connected to the power shaft 410 via a key. A bidirectional screw 62 is rotatably connected between the connecting rod 2 and one of the support frames 3. A small gear 63 is connected to the bidirectional screw 62 via a key. The small gear 63 is located above the large sector gear 61 and meshes with it. A movable support 64 is threaded onto the bidirectional screw 62. The power shaft 410 passes through the movable support 64, and another rotating roller 41 passes through the movable support 64. A fixed plate 65 is welded to the lower part of the movable support 64. Two lifting rods 66 are slidably connected to the fixed plate 65. The two lifting rods 66 are symmetrically arranged. Two return springs 67 are connected to the fixed plate 65 and the two lifting rods 66 through hooks. The return springs 67 are sleeved on the lifting rods 66. Two flattening rollers 68 are rotatably connected between the two lifting rods 66. The flattening rollers 68 are used to roll the overlapping part of the two roofing felts.

[0030] Initially, the two flattening rollers 68 press the asphalt felt under the action of the return springs 67. When the output shaft of the servo motor 49 drives the power shaft 410 to rotate, the power shaft 410 drives the large sector gear 61 to rotate. The rotation of the large sector gear 61 will intermittently drive the small gear 63 to rotate. The rotation of the small gear 63 will drive the bidirectional screw 62 to rotate. The rotation of the bidirectional screw 62 will drive the moving support 64 to move horizontally back and forth through the thread. The horizontal back and forth movement of the moving support 64 will drive the fixed plate 65 to move horizontally back and forth. The horizontal movement of the fixed plate 65 will drive the two lifting rods 66, the two flattening rollers 68 and the four return springs 67 to move horizontally back and forth. One of the flattening rollers 68 will reciprocate and roll the overlapping part of the two asphalt felts, and the other flattening roller 68 will reciprocate and roll the asphalt felt laid on the ground, which can make the two asphalt felts fit more tightly, thereby reducing the gap between the two asphalt felts.

[0031] Example 3: Based on Example 2, such as Figure 6 and Figure 7 As shown, it also includes a flattening and pressurizing mechanism, which is mounted on the connecting rod 2. The flattening and pressurizing mechanism includes a fixed rod 71, which is welded to the connecting rod 2. The bottom of the fixed rod 71 is connected to a slotted plate 72 by bolts. The slotted plate 72 has a guide groove. A fixed round rod 73 is welded between the tops of the two lifting rods 66. The end of the fixed round rod 73 away from the lifting rod 66 is located in the guide groove on the slotted plate 72.

[0032] When the fixed plate 65 moves both lifting rods 66 horizontally, the two lifting rods 66 together move the fixed round rod 73 horizontally along the guide groove on the slotted plate 72. During the horizontal movement of the fixed round rod 73, the slotted plate 72 will squeeze the fixed round rod 73 downward. The fixed round rod 73 will then move both lifting rods 66 downward. The two lifting rods 66 will then move both flattening rollers 68 downward. Then, the two lifting rods 66 and the two flattening rollers 68 will move upward under the action of the return spring 67. The upward movement of the two lifting rods 66 will together move the fixed round rod 73 upward. When the fixed plate 65 moves the two lifting rods 66 in the opposite horizontal direction to reset, the two lifting rods 66 will together move the fixed round rod 73 in the opposite horizontal direction along the guide groove on the slotted plate 72 to reset. In this way, the rolling pressure of the flattening roller 68 on the felt can be increased, further making the two felts fit together more tightly.

[0033] Example 4: Based on Example 3, such as Figure 6 As shown, it also includes a bonding rod 8, which is bolted between the lower parts of the two lifting rods 66. The bonding rod 8 is used to press and flatten the gap between the two oil felts. A side scraper 9 is bolted between the bottoms of the two lifting rods 66. The side scraper 9 is used to press and flatten the overlapping part of the two oil felts.

[0034] The bonding rod 8 and the side scraper 9 can squeeze and flatten the asphalt felt, further reducing the gap between the two asphalt felts.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
