Description

Technical Field

[0001] This invention belongs to the technical field of pipe jacking equipment, specifically a rectangular pipe jacking equipment for tunnels. Background Technology

[0002] Pipe jacking equipment is a type of equipment used in building construction, primarily in tunnel construction. Rectangular pipes used in tunnel construction need to be placed on the pipe jacking equipment, which lifts the rectangular pipes to facilitate subsequent installation and use.

[0003] A Chinese patent with publication number CN103938703A discloses a pipe jacking construction method. The key technical point is that all concrete pipes are connected and tightened using a concrete socket pipe structure, followed by grouting after the concrete pipes are tightened. This pipe jacking construction method not only facilitates stable equipment installation but also ensures convenient and safe construction, easy transportation of materials and waste soil, high pipe jacking accuracy, and applicability to pipe jacking construction in various regions.

[0004] However, when assembling existing rectangular jacking pipe bodies on the construction site, they all need to be placed on the jacking pipe erection equipment body first. When placing the rectangular jacking pipe body on the jacking pipe erection equipment body, a crane is used to lift it up. Since the traditional jacking pipe erection equipment body does not have a guiding device, it is difficult to successfully lift the rectangular jacking pipe body into the jacking pipe erection equipment body in one go. It requires multiple attempts before the rectangular jacking pipe body can be placed into the jacking pipe erection equipment body, which greatly reduces the efficiency of placing the rectangular jacking pipe body and affects the subsequent installation of the rectangular jacking pipe body.

[0005] Therefore, the present invention provides a tunnel rectangular pipe jacking erection device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A rectangular pipe jacking erection device for tunnels, comprising an erection device body and a rectangular pipe jacking body, wherein the top of the erection device body is provided with the rectangular pipe jacking body, and a rotating shaft is rotatably connected to the top of the erection device body. An "L"-shaped bracket is fixedly fitted onto the surface of the rotating shaft. An arc-shaped guide block is fixedly connected to the top of the bracket. The guide block is made of rubber, and a receiving groove is opened on one side of the guide block. A guide wheel is rotatably connected inside the receiving groove. Currently, when assembling the rectangular pipe jacking body on the construction site, it needs to be placed on the pipe jacking erection device body first. When placing the rectangular pipe jacking body on the pipe jacking device body, a crane is used to lift it. Because traditional pipe jacking device bodies do not have guiding devices, it is difficult to successfully lift the rectangular pipe jacking body into the pipe jacking device body in one attempt; multiple attempts are required before the rectangular pipe jacking body can be successfully placed into the pipe jacking device body. This significantly reduces the efficiency of placing the rectangular jacking pipe body and affects its subsequent installation. In this invention, when a crane lifts the rectangular jacking pipe body above the erecting equipment body, the body is positioned between two sets of guide blocks. As the jacking pipe body continues to descend, the support is compressed and rotates to match the shape of the pipe body. At this point, the side wall of the pipe body connects with the guide wheels in the receiving groove. As the pipe body continues to descend, the guide wheels assist in guiding it, correcting any misalignment and allowing for quick alignment with the erecting equipment body. Once the pipe body is fully inside the equipment, the two sets of guide blocks at the top of the equipment reset and become firmly attached to the pipe body, facilitating rapid installation and greatly improving the efficiency of placing the jacking pipe body into the equipment.

[0008] Preferably, a sliding rod is slidably connected inside the receiving groove, and a scraper is fixedly connected to the bottom of the sliding rod. A spring is fixedly connected to one end of the scraper near the sliding rod, and the other end of the spring is fixedly connected to the receiving groove. During operation, when the rectangular jacking pipe body contacts the guide wheel and moves, the rectangular jacking pipe body will be covered with mud due to its use at the tunnel construction site. The guide wheel will also pick up mud from the rectangular jacking pipe body when it rotates. When the guide wheel rotates into the receiving groove, the mud on the guide wheel will be scraped off by the scraper, thus preventing the mud from adhering to the guide wheel for a long time. When the scraper encounters mud that is too tightly adhered, it cannot scrape it off in one go. The scraper will slide away from the guide wheel through the sliding rod, thus passing over the mud that is too tightly adhered, making it easier for the scraper to continue scraping.

[0009] Preferably, a fixing plate is fixedly connected to the inner wall of the storage trough, and the fixing plate is arc-shaped. During operation, when the scraper scrapes the soil off the guide wheel, the soil will fall onto the fixing plate of the storage trough. Since the fixing plate is arc-shaped, it will guide the soil out of the storage trough, thereby preventing the soil from accumulating in the storage trough.

[0010] Preferably, an impact piece made of sheet metal is fixedly connected to one side of the fixed plate, a first magnet is fixedly connected to the top of the impact piece, and a second magnet is fixedly connected inside the guide wheel. During operation, when the guide wheel starts to rotate, it will rotate along with the second magnet inside. Since the second magnet and the first magnet are like poles and repel each other, the first magnet will carry the impact piece to impact the fixed plate, causing the fixed plate to vibrate, thereby reducing the occurrence of blockage between the fixed plate and the guide wheel and playing a role in unblocking.

[0011] Preferably, a rod is fixedly connected to the bottom of the impact plate, and a draining rod is fixedly connected to one side of the impact plate. During operation, when the impact plate swings and impacts, it will swing along with the rod and the draining rod. The rod breaks up the soil, making it smaller and easier to flow. The draining rod is inserted into the soil and swings to facilitate the drainage of the soil between the fixed plate and the guide wheel, thus further clearing the soil and allowing it to flow out of the collection trough.

[0012] Preferably, a sliding groove is provided on one side of the bracket, and a sliding block is slidably connected inside the sliding groove. The top of the sliding block is fixedly connected to a guide block, and a pressure plate is fixedly connected to the bottom of the sliding block. A rubber water tank is fixedly connected to one side of the bracket, and the water tank is located directly below the pressure plate. A guide pipe is fixedly connected to the bottom of the water tank. During operation, when the rubber guide block is squeezed, the guide block will deform, thereby squeezing the sliding block in the sliding groove. This causes the sliding block to slide towards the water tank along with the pressure plate. The pressure plate squeezes the rubber water tank, which is pre-stored with hot water and has an insulation layer inside. The hot water in the tank is sprayed out to the rotating shaft through the guide pipe, thereby heating the rotating shaft. This prevents snow water from splashing onto the rotating shaft when the equipment is used outdoors in winter, causing the rotating shaft to freeze and become unable to rotate.

[0013] Preferably, two curved plastic tubes are fixedly connected to both sides of the guide tube. The inner wall of the curved tubes is provided with water spray nozzles. A third magnet and a metal connecting block are fixedly connected to the ends of the two sets of curved tubes that are close to each other. During operation, when placing the curved tubes, the two sets of curved tubes are placed on both sides of the rotating shaft. After the two sets of curved tubes are placed, since the curved tubes are made of plastic, they can deform. The bottom ends of the two sets of curved tubes are rotated in the direction that they are close to each other. At this time, the third magnet and the metal connecting block at one end attract and fix each other, thereby fixing the two sets of curved tubes. This allows the water sprayed from the curved tubes to heat the rotating shaft from all directions, further facilitating the rotation of the rotating shaft.

[0014] Preferably, a guide block is fixedly connected inside the guide pipe, and a through hole is opened in the middle of the guide block. The two sides of the guide block are arc-shaped. When hot water flows into the guide pipe during operation, because the two sides of the guide block are arc-shaped, some hot water will flow through the arc-shaped guide block to the arc-shaped pipes on both sides, and the hot water between the guide pipes will flow away through the through hole, thereby heating the rotating shaft at the bottom of the guide pipe and realizing the diversion of hot water in the guide pipe.

[0015] Preferably, a rectangular groove is provided on one side of the flow guide block, and a rectangular plate is fixedly connected inside the rectangular groove. A fan blade is rotatably connected to the bottom of the rectangular plate. During operation, when hot water flows to the arc-shaped part of the flow guide block, some hot water will continue to flow down through the rectangular groove. When the hot water impacts the arc-shaped fan blade, it will drive the fan blade to rotate. The fan blade will spread the hot water in all directions, further enabling the hot water to heat the rotating shaft from all directions.

[0016] Preferably, a corrugated pipe is fixedly connected to the inner wall of the chute, and the other end of the corrugated pipe is fixedly connected to the sliding block. During operation, when the sliding block slides, it will stretch and move along with the corrugated pipe, thereby keeping the chute in a closed whole and preventing dust and dirt from the construction site from entering the chute and affecting the normal use of the sliding block.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention provides a rectangular tunnel jacking installation device. Using guide blocks and a receiving groove, when a crane lifts the rectangular jacking pipe body above the installation device, the rectangular jacking pipe body is positioned between two sets of guide blocks. As the rectangular jacking pipe body continues to descend, the support structure is compressed and rotates to conform to the shape of the rectangular jacking pipe body. At this point, the side wall of the rectangular jacking pipe body connects with the guide wheels in the receiving groove. As the rectangular jacking pipe body continues to descend, the guide wheels assist in guiding the rectangular jacking pipe body, correcting any misalignment. The rectangular jacking pipe body can be quickly aligned with the installation device body. Once the rectangular jacking pipe body is fully inside the installation device body, the two sets of guide blocks at the top of the installation device body reset and become firmly attached to the rectangular jacking pipe body. This facilitates the rapid lifting of the rectangular jacking pipe body into the installation device body, significantly improving the efficiency of placing the jacking pipe body into the installation device body.

[0019] 2. This invention provides a rectangular tunnel jacking device. Through a chute and a sliding block, when a rubber guide block is compressed, the guide block deforms, thereby compressing the sliding block within the chute. This causes the sliding block, carrying a pressure plate, to slide towards a water tank. The pressure plate compresses the rubber water tank, which is pre-stored with hot water and has an internal insulation layer. The hot water is sprayed through a guide pipe to the rotating shaft, heating it. This prevents snowmelt from freezing the rotating shaft during outdoor use in winter, thus preventing it from rotating. Attached Figure Description

[0030] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0031] Example 1:

[0032] Please see Figures 1-3As shown in the embodiment of the present invention, a rectangular tunnel jacking device includes a device body 2 and a rectangular jacking pipe body 1. The rectangular jacking pipe body 1 is mounted on the top of the device body 2. A rotating shaft 4 is rotatably connected to the top of the device body 2. An "L"-shaped bracket 3 is fixedly fitted onto the surface of the rotating shaft 4. An arc-shaped guide block 5 is fixedly connected to the top of the bracket 3. The guide block 5 is made of rubber, and a storage groove 6 is opened on one side of the guide block 5. A guide wheel 7 is rotatably connected inside the storage groove 6. When assembling the existing rectangular jacking pipe body 1 on the construction site, it needs to be placed on the jacking pipe jacking device body 2 first. When placing the rectangular jacking pipe body 1 on the jacking pipe jacking device body 2, a crane is used to lift it. Since the traditional jacking pipe jacking device body 2 does not have a guiding device, it is difficult to successfully lift the rectangular jacking pipe body 1 into the jacking pipe jacking device body 2 in one attempt. Multiple attempts are required before the rectangular jacking pipe body 1 can be successfully placed into the jacking pipe jacking device body 2, thus greatly reducing the time required. The previous method reduced the efficiency of placing the rectangular jacking pipe body 1 and affected its subsequent installation. In this invention, when the rectangular jacking pipe body 1 is hoisted above the erecting equipment body 2 using a crane, it is positioned between two sets of guide blocks 5. As the rectangular jacking pipe body 1 continues to be lowered, the support 3 is compressed and rotates to match the shape of the rectangular jacking pipe body 1. At this point, the side wall of the rectangular jacking pipe body 1 connects with the guide wheels 7 in the receiving groove 6. As the rectangular jacking pipe body 1 continues to move downwards, the guide wheels 7 assist in guiding the rectangular jacking pipe body 1, correcting any misalignment. The rectangular jacking pipe body 1 can then be quickly aligned with the erecting equipment body 2. Once the rectangular jacking pipe body 1 is fully inside the erecting equipment body 2, the two sets of guide blocks at the top of the erecting equipment body 2 will reset and fit snugly against the rectangular jacking pipe body 1, facilitating the rapid hoisting of the rectangular jacking pipe body 1 into the erecting equipment body 2 and greatly improving the efficiency of placing the jacking pipe body into the erecting equipment body 2.

[0033] The storage groove 6 is slidably connected to a sliding rod 8. A scraper 9 is fixedly connected to the bottom of the sliding rod 8. A spring 10 is fixedly connected to one end of the scraper 9 near the sliding rod 8. The other end of the spring 10 is fixedly connected to the storage groove 6. During operation, when the rectangular jacking pipe body 1 contacts the guide wheel 7 and moves, the rectangular jacking pipe body 1 will be covered with mud because it is used at the tunnel construction site. The guide wheel 7 will also be covered with mud when it rotates. When the guide wheel 7 rotates into the storage groove 6, the mud on the guide wheel 7 will be scraped off by the scraper 9, thus preventing the mud from adhering to the guide wheel 7 for a long time. When the scraper 9 encounters mud that is too tightly adhered, the scraper 9 cannot scrape it off at once. The scraper 9 will slide away from the guide wheel 7 through the sliding rod 8, thus passing over the mud that is too tightly adhered, making it easier for the scraper 9 to continue scraping.

[0034] The inner wall of the storage trough 6 is fixedly connected to a fixing plate 11, which is arc-shaped. During operation, when the scraper 9 scrapes the soil off the guide wheel 7, the soil will fall onto the fixing plate 11 of the storage trough 6. Since the fixing plate 11 is arc-shaped, it will guide the soil out of the storage trough 6, thereby preventing the accumulation of soil in the storage trough 6.

[0035] A sheet metal impact piece 12 is fixedly connected to one side of the fixed plate 11, and a first magnet 13 is fixedly connected to the top of the impact piece 12. A second magnet 14 is fixedly connected inside the guide wheel 7. When working, when the guide wheel 7 starts to rotate, it will rotate the second magnet 14 inside it. Since the second magnet 14 and the first magnet 13 are like poles and repel each other, the first magnet 13 will carry the impact piece 12 to impact the fixed plate 11, causing the fixed plate 11 to vibrate. This reduces the blockage between the fixed plate 11 and the guide wheel 7 and plays a role in clearing blockage.

[0036] The bottom of the impact plate 12 is fixedly connected to the insertion rod 15, and one side of the impact plate 12 is fixedly connected to the unblocking rod 16. When working, the impact plate 12 swings and impacts, and it swings together with the insertion rod 15 and the unblocking rod 16. The insertion rod 15 breaks up the soil, making the soil smaller and easier to flow. The unblocking rod 16 is inserted into the soil and swings, which facilitates the unblocking of the soil between the fixed plate 11 and the guide wheel 7, and plays a further unblocking role, so that the soil can flow out of the collection trough 6.

[0037] like Figures 4-6 As shown, a sliding groove 31 is provided on one side of the bracket 3. A sliding block 17 is slidably connected inside the sliding groove 31. The top of the sliding block 17 is fixedly connected to the guide block 5, and a pressure plate 18 is fixedly connected to the bottom of the sliding block 17. A rubber water tank 19 is fixedly connected to one side of the bracket 3. The water tank 19 is located directly below the pressure plate 18, and a guide pipe 20 is fixedly connected to the bottom of the water tank 19. During operation, when the rubber guide block 5 is compressed, the guide block 5 will produce... The deformation causes the sliding block 17 in the chute 31 to be squeezed, which in turn causes the sliding block 17 to slide towards the water tank 19 along with the pressure plate 18. The pressure plate 18 squeezes the rubber water tank 19, which is pre-stored with hot water and has an insulation layer inside. The hot water in the water tank 19 is sprayed out to the rotating shaft 4 through the guide pipe 20, thereby heating the rotating shaft 4. This prevents snow water from splashing onto the rotating shaft 4 when the equipment body 2 is used outdoors in winter, causing the rotating shaft 4 to freeze and become unable to rotate.

[0038] Plastic arc-shaped tubes 21 are fixedly connected to both sides of the guide tube 20. The inner wall of the arc-shaped tube 21 is provided with a water spray nozzle 22. A third magnet 23 and a metal connecting block 24 are fixedly connected to the ends of the two sets of arc-shaped tubes 21 that are close to each other. During operation, when placing the arc-shaped tubes 21, the two sets of arc-shaped tubes 21 are sleeved on both sides of the rotating shaft 4. After the two sets of arc-shaped tubes 21 are sleeved, since the arc-shaped tubes 21 are made of plastic, they can deform. The bottom ends of the two sets of arc-shaped tubes 21 are rotated in the direction that they are close to each other. At this time, the third magnet 23 and the metal connecting block 24 at one end attract and fix each other, thereby fixing the two sets of arc-shaped tubes 21. This allows the water sprayed from the arc-shaped tubes 21 to heat the rotating shaft 4 from all directions, further facilitating the rotation of the rotating shaft 4.

[0039] A flow guide block 25 is fixedly connected inside the flow guide pipe 20. A through hole 26 is opened in the middle of the flow guide block 25, and the two sides of the flow guide block 25 are arc-shaped. When hot water flows into the flow guide pipe 20, because the two sides of the flow guide block 25 are arc-shaped, some hot water will flow through the arc-shaped flow guide block 25 to the arc-shaped pipes 21 on both sides, and the hot water between the flow guide pipes 20 will flow away through the through hole 26, thereby heating the rotating shaft 4 at the bottom of the flow guide pipe 20, and realizing the diversion of hot water in the flow guide pipe 20.

[0040] A rectangular groove 27 is provided on one side of the flow guide block 25. A rectangular plate 28 is fixedly connected inside the rectangular groove 27. A fan blade 29 is rotatably connected to the bottom of the rectangular plate 28. During operation, when hot water flows to the arc-shaped part of the flow guide block 25, some hot water will continue to flow down through the rectangular groove 27. When the hot water impacts the arc-shaped fan blade 29, it will drive the fan blade 29 to rotate. The fan blade 29 will spread the hot water in all directions, further enabling the hot water to heat the rotating shaft 4 in all directions.

[0041] Example 2:

[0042] like Figure 7 As shown in Example 1, another embodiment of the present invention is as follows:

[0043] A corrugated pipe 30 is fixedly connected to the inner wall of the slide 31, and the other end of the corrugated pipe 30 is fixedly connected to the sliding block 17. During operation, when the sliding block 17 slides, it will stretch and move the corrugated pipe 30 together, so that the slide 31 is in a closed whole, preventing dust and dirt from the construction site from entering the slide 31 and affecting the normal use of the sliding block 17.

[0044] Working principle: When the rectangular jacking pipe body 1 is hoisted above the erecting equipment body 2 using a crane, the rectangular jacking pipe body 1 is positioned between the two sets of guide blocks 5. As the rectangular jacking pipe body 1 continues to be lowered, the support 3 is compressed and rotates, thus conforming to the shape of the rectangular jacking pipe body 1. At this point, the side wall of the rectangular jacking pipe body 1 connects with the guide wheels 7 in the receiving groove 6. As the rectangular jacking pipe body 1 continues to move downward, the guide wheels 7 assist in guiding the rectangular jacking pipe body 1, correcting any misalignment. The rectangular jacking pipe body 1 can then be quickly aligned with the erecting equipment body 2. Once the rectangular jacking pipe body 1 is fully inside the erecting equipment body 2, the two sets of guide blocks at the top of the erecting equipment body 2 will reset, thus fitting and fixing the rectangular jacking pipe body 1 together. This facilitates the rapid hoisting of the rectangular jacking pipe body 1 into the erection equipment body 2, greatly improving the efficiency of placing the jacking pipe body into the erection equipment body 2. When the rectangular jacking pipe body 1 contacts the guide wheel 7 and moves, because the rectangular jacking pipe body 1 is used at the tunnel construction site, it will be covered with mud. The guide wheel 7 will also pick up mud from the rectangular jacking pipe body 1 as it rotates. When the guide wheel 7 rotates into the receiving groove 6, the mud on the guide wheel 7 will be scraped off by the scraper 9, thus preventing the mud from adhering to the guide wheel 7 for a long time. When the scraper 9 encounters mud that is too tightly adhered, it cannot scrape it off in one go. The scraper 9 will slide away from the guide wheel 7 via the sliding rod 8, thus passing over the tightly adhered mud and facilitating scraping. Scraper 9 continues scraping. After scraping the dirt off the guide wheel 7, the dirt falls onto the fixed plate 11 of the collection trough 6. Since the fixed plate 11 is curved, it guides the dirt into the collection trough 6, preventing dirt accumulation. When the guide wheel 7 starts to rotate, it rotates the internal second magnet 14. Since the second magnet 14 and the first magnet 13 are like poles and repel each other, the first magnet 13 will impact the impact plate 12 towards the fixed plate 11, causing the fixed plate 11 to vibrate. This reduces blockage between the fixed plate 11 and the guide wheel 7, thus clearing the blockage. When the impact plate 12 swings and impacts, it will swing the insertion rod 15 and the unblocking rod 16 together. The insertion rod 15 breaks up the dirt, making it more compact. The mud is made smaller to facilitate flow. The dredging rod 16 is inserted into the mud and swings to facilitate the clearing of mud between the fixed plate 11 and the guide wheel 7, further clearing the mud and allowing it to flow out of the collection trough 6. When the rubber guide block 5 is squeezed, it deforms, which in turn squeezes the sliding block 17 in the chute 31. This causes the sliding block 17 to slide towards the water tank 19 along with the pressure plate 18. The pressure plate 18 squeezes the rubber water tank 19, which is pre-stored with hot water and has an internal insulation layer. The hot water in the water tank 19 is sprayed out through the guide pipe 20 to the rotating shaft 4, thereby heating the rotating shaft 4. This prevents snowmelt from dripping onto the rotating shaft 4 and causing it to freeze when the equipment body 2 is used outdoors in winter.Therefore, rotation is impossible. When placing the arc-shaped tubes 21, two sets of arc-shaped tubes 21 are fitted onto both sides of the rotating shaft 4. After the two sets of arc-shaped tubes 21 are fitted, since the arc-shaped tubes 21 are made of plastic, they can deform. Rotating the bottom ends of the two sets of arc-shaped tubes 21 towards each other, the third magnet 23 at one end and the metal connecting block 24 at the other end attract and fix each other, thereby fixing the two sets of arc-shaped tubes 21. This allows the water sprayed from the arc-shaped tubes 21 to heat the rotating shaft 4 from all directions, further facilitating the rotation of the rotating shaft 4. When hot water flows inside the guide pipe 20, it is... The guide block 25 has an arc shape on both sides, so some hot water flows through the arc-shaped guide block 25 to the arc-shaped pipes 21 on both sides. Hot water between the guide pipes 20 flows away through the through holes 26, thus heating the rotating shaft 4 at the bottom of the guide pipe 20, achieving diversion of the hot water within the guide pipe 20. When the hot water flows to the arc-shaped part of the guide block 25, some hot water continues to flow down through the rectangular groove 27. When the hot water impacts the arc-shaped fan blades 29, it drives the fan blades 29 to rotate, dispersing the hot water in all directions, further ensuring that the hot water heats the rotating shaft 4 from all angles.

[0045] 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.
