Description

Technical Field

[0001] This invention belongs to the field of pipe gallery construction technology, specifically a prefabricated pipe gallery translation and jacking device. Background Technology

[0002] A utility tunnel is an underground corridor for pipelines and electrical circuits. To facilitate maintenance and improve the city's appearance, a tunnel space is built underground in the city to integrate various engineering pipelines, making it convenient for unified planning, design, construction and management. It is an important infrastructure to ensure the operation of the city.

[0003] Most existing utility tunnels are prefabricated. They are prefabricated in a factory using molds. After the prefabricated utility tunnels are completed, they are transported to the construction site for assembly. During construction, an inverted trapezoidal burial trench is dug along the route of the utility tunnel to be buried. A crane is used to lift the prefabricated utility tunnel into the burial trench. The prefabricated utility tunnels are then connected end to end to form a utility tunnel. Soil is then backfilled and a road is laid on the surface.

[0004] When using a crane to lift the utility tunnel to the bottom of the burial trench, multiple construction workers are needed to coordinate with the crane to lift and adjust the tunnel multiple times. This results in the tunnel sections being connected end to end, and the size of the gaps between each section directly affects the quality of the entire tunnel. If the gaps between the sections are too large, it will make the subsequent filling and sealing with concrete difficult, and may even cause water leakage. If the gaps between the sections are too small, it will cause the sections to be squeezed and collided, resulting in damage to the tunnel.

[0005] Therefore, the present invention provides a prefabricated pipe gallery translation and jacking 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 prefabricated pipe gallery translation and jacking device of this invention includes a tracked vehicle body. A fixed frame is fixedly connected to the top surface of the front of the tracked vehicle body. A jacking arm is rotatably mounted in the middle of the fixed frame. An extension arm is slidably mounted in the middle of the jacking arm. A horizontal beam is provided at the end of the extension arm away from the fixed frame. A jacking hydraulic cylinder is fixedly connected to the top of the jacking arm. The piston rod end of the jacking hydraulic cylinder is fixedly connected to the top of the end of the extension arm near the horizontal beam. After the prefabricated pipe gallery is manufactured, it is transported to the construction site for assembly and construction, utilizing… The crane lifts the precast pipe gallery into the embedment trench. At this time, the construction workers control the tracked vehicle to approach the precast pipe gallery to be assembled, and lower the jacking arm to keep it horizontal. This allows the horizontal beam to fit against the middle of the precast pipe gallery. The jacking hydraulic cylinder pushes the extension arm to slide from the middle of the jacking arm, pushing the horizontal beam to move and pushing the precast pipe gallery to be assembled closer to the assembled precast pipe gallery, maintaining the specified gap. This completes the translation and jacking work of the precast pipe gallery, reducing the difficulty of the construction workers' work, making it easier for the workers to control the gap between the precast pipe galleries, and improving the construction quality of the pipe gallery tunnel.

[0008] Preferably, a connecting seat is bolted to one end of the extension arm near the horizontal beam, the connecting seat is fixedly connected to the middle of the horizontal beam, and both ends of the horizontal beam are provided with sliding grooves. A sliding arm is slidably installed inside the sliding groove, and an inner cavity is provided in the middle of the sliding arm. A translation hydraulic cylinder is fixedly connected to one end of the sliding groove near the middle of the horizontal beam. The outer ring of the translation hydraulic cylinder is fitted inside the inner ring of the inner cavity, and the piston rod end of the translation hydraulic cylinder is fixedly connected to the end of the inner cavity; thereby increasing the applicability of the translation and pushing device.

[0009] Preferably, guide rails are fixedly connected to the top and bottom of the side of the sliding arm away from the connecting seat. Slider blocks are slidably installed at both ends of the top and bottom guide rails. L-shaped plates are fixedly connected to the sides of the two sliders on the same side away from the sliding arm, and the bent parts of the two L-shaped plates are close to each other. This reduces the probability of tilting when the precast pipe gallery is pushed horizontally. At the same time, when there is a misalignment between the precast pipe gallery to be assembled and the precast pipe gallery after assembly, the construction personnel control the retraction of the translation hydraulic cylinder on one side, which drives the four L-shaped plates to translate sequentially, thereby pushing the precast pipe gallery to be assembled to translate, so that the precast pipe gallery to be assembled is aligned with the precast pipe gallery after assembly, which facilitates the construction personnel to adjust the position of the precast pipe gallery, thereby improving the accuracy of the precast pipe gallery assembly.

[0010] Preferably, a fixing groove is provided in the middle of the side of the sliding arm away from the connecting seat, and a fixing block is slidably installed inside the fixing groove. A U-shaped plate is fixedly connected to the side of the L-shaped plate away from the connecting seat. The fixing block and the U-shaped plate are fixedly connected by bolts, and the fixing block is in contact with the L-shaped plate. This not only fixes and connects the L-shaped plate, but also supports the L-shaped plate, thereby improving the support strength of the L-shaped plate.

[0011] Preferably, lifting hydraulic cylinders are rotatably mounted on both sides of the fixed frame, and slide rails are fixedly connected to both sides of the middle part of the jacking arm. Support blocks are slidably installed inside the slide rails, and the piston rod end of the lifting hydraulic cylinder is rotatably connected to the support block; thereby facilitating the movement of the tracked vehicle body and making it easier for construction personnel to adjust the vertical position of the precast pipe gallery jacking.

[0012] Preferably, a support frame is rotatably mounted on one end of the push arm near the extension arm, a main shaft is rotatably mounted on the bottom of the support frame, a pair of support wheels are rotatably mounted on the outer rings of both ends of the main shaft, and a support roller is fixedly connected to the top side of the middle part of the support frame. The outer wall of the support roller is in sliding fit with the bottom surface of the push arm. The support roller contacts the bottom surface of the push arm, and the support frame and the push arm form a large angle, thereby providing auxiliary support for the push arm and improving the working stability of the translational push device.

[0013] Preferably, both sides of the push arm near the extension arm are rotatably equipped with adjusting hydraulic cylinders, and the piston rod end of the adjusting hydraulic cylinder is rotatably connected to the middle of the support frame; by setting the adjusting hydraulic cylinder, the rotation of the support frame is driven, realizing the expansion and retraction of the support frame, which is convenient for construction personnel to operate.

[0014] Preferably, positioning posts are fixedly connected to both sides of the connecting seat near the extension arm, and positioning holes are opened on both sides of the end of the extension arm near the connecting seat. The outer wall of the positioning post slides into the inner wall of the positioning hole. The positioning post is inserted into the positioning hole to initially position and connect the connecting seat and the extension arm. The through hole of the connecting seat and the extension arm is connected, which facilitates the installation of bolts by the staff, thereby facilitating the installation work of the staff.

[0015] Preferably, a blocking push post is fixedly connected to the bottom surface of the connecting seat. The blocking push post has an arc-shaped surface at one end near the extension arm. The arc-shaped surface of the blocking push post slides in cooperation with the outer wall of the support roller. This fixes the support roller and reduces the impact of the support frame on the movement of the tracked vehicle body.

[0016] Preferably, a top support block is fixed to the end of the sliding arm away from the connecting seat, and multiple anti-slip grooves are evenly provided on the outer wall of the top support block; the anti-slip grooves increase the friction between the precast pipe gallery and the top support block, thereby pulling the precast pipe gallery outward and increasing the gap between the precast pipe galleries.

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

[0018] 1. The precast pipe gallery translation and jacking device of the present invention comprises a tracked vehicle body, a fixed frame, a jacking arm, an extension arm, a horizontal beam, and a jacking hydraulic cylinder. After the precast pipe gallery is manufactured, it is transported to the construction site for assembly. A crane is used to lift the precast pipe gallery into the embedment trench. At this time, the construction personnel control the tracked vehicle body to approach the precast pipe gallery to be assembled, lower the jacking arm so that the jacking arm is kept horizontal, and the horizontal beam is attached to the middle of the precast pipe gallery. The jacking hydraulic cylinder pushes the extension arm to slide from the middle of the jacking arm, pushing the horizontal beam to move, and pushing the precast pipe gallery to be assembled closer to the assembled precast pipe gallery, maintaining a specified gap, thereby completing the translation and jacking work of the precast pipe gallery. This reduces the difficulty of the construction personnel's work, makes it easier for the staff to control the gap between the precast pipe galleries, and improves the construction quality of the pipe gallery tunnel.

[0019] 2. The precast pipe gallery translation and jacking device of the present invention comprises a connecting seat, sliding arms, translation hydraulic cylinders, guide rails, sliders, and L-shaped plates. Based on the actual width of the precast pipe gallery, the translation hydraulic cylinders on both sides are controlled to push the sliding arms along the sliding grooves, and the sliders along the guide rails, so that the L-shaped plates on both sides clamp and fix the side walls of the precast pipe gallery. When there is a misalignment between the precast pipe gallery to be assembled and the precast pipe gallery after assembly, the construction personnel control the translation hydraulic cylinder on one side to retract and the translation hydraulic cylinder on the other side to extend, causing the sliding arms on both sides to translate to one side, driving the four L-shaped plates to translate sequentially, thereby pushing the precast pipe gallery to be assembled to translate, aligning the precast pipe gallery to be assembled with the precast pipe gallery after assembly, thus increasing the applicability of the translation and jacking device.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figures 1 to 3 As shown in the embodiment of the present invention, a precast pipe gallery translation and jacking device includes a tracked vehicle body 1. A fixed frame 2 is fixedly connected to the top surface of the front of the tracked vehicle body 1. A jacking arm 3 is rotatably mounted in the middle of the fixed frame 2. An extension arm 4 is slidably mounted in the middle of the jacking arm 3. A horizontal beam 5 is provided at the end of the extension arm 4 away from the fixed frame 2. A jacking hydraulic cylinder 6 is fixedly connected to the top of the jacking arm 3. The piston rod end of the jacking hydraulic cylinder 6 is fixedly connected to the top of the end of the extension arm 4 near the horizontal beam 5. In this embodiment, the tracked vehicle body 1 is a tracked chassis with a power structure and a cab on the top. The tracked vehicle body 1 is similar to the body structure of an excavator. During operation, the precast pipe gallery... After fabrication, the precast pipe gallery is transported to the construction site for assembly. A crane is used to lift the precast pipe gallery into the embedding trench. At this time, the construction personnel control the tracked vehicle 1 to approach the precast pipe gallery to be assembled, and lower the jacking arm 3 to keep the jacking arm 3 horizontal. This allows the horizontal beam 5 to fit against the middle of the precast pipe gallery. The jacking hydraulic cylinder 6 pushes the extension arm 4 to slide from the middle of the jacking arm 3, pushing the horizontal beam 5 to move and pushing the precast pipe gallery to be assembled closer to the assembled precast pipe gallery, maintaining the specified gap. This completes the translation and jacking work of the precast pipe gallery, reducing the difficulty of the construction personnel's work, making it easier for the staff to control the gap between the precast pipe galleries, and improving the construction quality of the pipe gallery tunnel.

[0028] like Figures 1 to 3As shown, a connecting seat 7 is bolted to one end of the extension arm 4 near the horizontal beam 5. The connecting seat 7 is fixedly connected to the middle of the horizontal beam 5. Slide grooves 8 are provided at both ends of the horizontal beam 5. Slide arms 9 are slidably installed inside the slide grooves 8. An inner cavity 10 is provided in the middle of the slide arm 9. A translation hydraulic cylinder 11 is fixedly connected to one end of the slide groove 8 near the middle of the horizontal beam 5. The outer ring of the translation hydraulic cylinder 11 is fitted inside the inner ring of the inner cavity 10. The piston rod end of the translation hydraulic cylinder 11 is fixedly connected to the end of the inner cavity 10. During operation, according to the actual width of the precast pipe gallery, the translation hydraulic cylinders 11 on both sides are controlled to push the slide arms 9 to slide along the slide grooves 8, so that the outer wall of the slide arms 9 always fits against the outer walls of both sides of the precast pipe gallery, thereby increasing the applicable range of the translation and pushing device.

[0029] like Figures 1 to 3 As shown, guide rails 12 are fixedly connected to the top and bottom of the side of the sliding arm 9 away from the connecting seat 7. Sliding blocks 13 are slidably installed at both ends of the guide rails 12 at the top and bottom. L-shaped plates 14 are fixedly connected to the sides of the two sliding blocks 13 on the same side away from the sliding arm 9, with the bent portions of the two L-shaped plates 14 close to each other. During operation, after the position of the sliding arm 9 is adjusted, the sliding blocks 13 are slidably installed on the guide rails 12. Pushing the sliding blocks 13 along the guide rails 12 causes the L-shaped plates 14 on both sides to clamp and fix the side walls of the precast pipe gallery, thereby reducing the impact on the precast pipe gallery. The probability of tilting during the horizontal pushing of the pipe gallery; at the same time, when there is a misalignment between the precast pipe gallery to be assembled and the precast pipe gallery after assembly, the construction personnel control the retraction of the translation hydraulic cylinder 11 on one side and the extension of the translation hydraulic cylinder 11 on the other side, so that the sliding arms 9 on both sides move to one side, driving the four L-shaped plates 14 to move sequentially, thereby pushing the precast pipe gallery to be assembled to move horizontally, so that the precast pipe gallery to be assembled is aligned with the precast pipe gallery after assembly, which facilitates the construction personnel to adjust the position of the precast pipe gallery, thereby improving the accuracy of the precast pipe gallery assembly.

[0030] like Figures 1 to 3 As shown, a fixing groove 15 is provided in the middle of the side of the sliding arm 9 away from the connecting seat 7. A fixing block 16 is slidably installed inside the fixing groove 15. A U-shaped plate 17 is fixedly connected to the side of the L-shaped plate 14 away from the connecting seat 7. The fixing block 16 and the U-shaped plate 17 are fixedly connected by bolts, and the fixing block 16 is in contact with the L-shaped plate 14. During operation, after adjusting the L-shaped plates 14 on both sides to clamp and fix the side walls on both sides of the prefabricated pipe gallery, the fixing block 16 is slid into the fixing groove 15, so that the fixing block 16 slides to the position of the L-shaped plate 14, so that the bolt on the fixing block 16 is inserted into the groove of the U-shaped plate 17 and the bolt is locked. This not only fixes and connects the L-shaped plate 14, but also supports the L-shaped plate 14, improving the support strength of the L-shaped plate 14.

[0031] like Figures 1 to 3As shown, lifting hydraulic cylinders 18 are rotatably mounted on both sides of the fixed frame 2, and slide rails 19 are fixedly connected to both sides of the middle part of the push arm 3. Support blocks 20 are slidably installed inside the slide rails 19, and the piston rod end of the lifting hydraulic cylinder 18 is rotatably connected to the support block 20. When the tracked vehicle body 1 needs to move during operation, the lifting hydraulic cylinder 18 pushes the support block 20 to slide along the slide rail 19, pushes the push arm 3 to rotate upward along the fixed frame 2, and lifts the push arm 3, thereby facilitating the movement of the tracked vehicle body 1. At the same time, it is convenient for construction personnel to adjust the vertical position of the precast pipe gallery push.

[0032] like Figures 1 to 3 As shown, a support frame 21 is rotatably mounted on one end of the push arm 3 near the extension arm 4. A main shaft 22 is rotatably mounted on the bottom of the support frame 21. A pair of support wheels 23 are rotatably mounted on the outer rings of both ends of the main shaft 22. A support roller 24 is fixedly connected to the top side of the middle part of the support frame 21. The outer wall of the support roller 24 slides in contact with the bottom surface of the push arm 3. During operation, when the push arm 3 is lowered to a horizontal position, the support frame 21 is rotated at the same time, so that the support wheels 23 contact the ground. At this time, the support roller 24 contacts the bottom surface of the push arm 3. At this time, the support frame 21 and the push arm 3 form a large angle, thereby providing auxiliary support for the push arm 3 and improving the working stability of the translation and pushing device.

[0033] like Figures 1 to 3 As shown, both sides of the push arm 3 near the extension arm 4 are rotatably equipped with adjusting hydraulic cylinders 25. The piston rod end of the adjusting hydraulic cylinder 25 is rotatably connected to the middle of the support frame 21. The adjusting hydraulic cylinder 25 drives the rotation of the support frame 21, realizing the expansion and retraction of the support frame 21, which is convenient for construction personnel to operate.

[0034] like Figures 1 to 3 As shown, positioning posts 26 are fixedly connected to both sides of the connecting seat 7 near the extension arm 4, and positioning holes 27 are opened on both sides of the end of the extension arm 4 near the connecting seat 7. The outer wall of the positioning post 26 slides in fit with the inner wall of the positioning hole 27. When installing the horizontal beam 5, the connecting seat 7 is bolted to the extension arm 4. First, the positioning post 26 is inserted into the interior of the positioning hole 27 to initially position and connect the connecting seat 7 and the extension arm 4. At the same time, the through hole of the connecting seat 7 and the extension arm 4 is connected, which facilitates the installation of bolts by the workers, thereby facilitating the installation work.

[0035] like Figures 1 to 3As shown, a blocking push column 28 is fixedly connected to the bottom surface of the connecting seat 7. The blocking push column 28 has an arc-shaped surface at one end near the extension arm 4. The arc-shaped surface of the blocking push column 28 slides in cooperation with the outer wall of the support roller 24. During operation, after the prefabricated pipe gallery is translated and pushed, the tracked vehicle body 1 needs to be moved. The hydraulic cylinder 25 is adjusted to retract the support frame 21, so that the support frame 21 rotates and fits against the bottom surface of the push arm 3. The push hydraulic cylinder 6 pulls the extension arm 4 into the interior of the push arm 3. At the same time, it drives the blocking push column 28 to translate to the bottom of the support roller 24 and contact the support roller 24 to fix the support roller 24, thereby reducing the impact of the support frame 21 on the movement of the tracked vehicle body 1.

[0036] Example 2

[0037] like Figure 4 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a top support block 29 is fixedly connected to one end of the sliding arm 9 away from the connecting seat 7, and a plurality of anti-slip grooves 30 are evenly opened on the outer wall of the top support block 29; during operation, when the gap between the prefabricated pipe racks is small, the horizontal beam 5 moves to the middle of the prefabricated pipe rack, and the translation hydraulic cylinder 11 pushes the sliding arm 9 to slide out from the inside of the sliding groove 8, pushing the top support blocks 29 on both sides to squeeze the inner walls of the two sides of the prefabricated pipe rack. The friction between the prefabricated pipe rack and the top support block 29 is increased by the anti-slip grooves 30. The pushing hydraulic cylinder 6 pulls the extension arm 4 into the inside of the pushing arm 3, thereby pulling the prefabricated pipe rack outward and increasing the gap between the prefabricated pipe racks.

[0038] Working principle: After the prefabricated pipe gallery is manufactured, it is transported to the construction site for assembly. A crane is used to lift the prefabricated pipe gallery into the burial trench. The construction personnel control the tracked vehicle 1 to approach the prefabricated pipe gallery to be assembled. At this time, the lifting hydraulic cylinder 18 pushes the support block 20 to slide along the slide rail 19, and pushes the top push arm 3 to rotate upward along the fixed frame 2, lifting the top push arm 3. The construction personnel control the lifting hydraulic cylinder 18 to lower the top push arm 3 to a horizontal state.

[0039] According to the actual width of the precast pipe gallery, the translation hydraulic cylinders 11 on both sides are controlled to push the sliding arm 9 to slide along the slide groove 8, and the slider 13 is slidably installed on the guide rail 12. The slider 13 is pushed to slide along the guide rail 12, so that the L-shaped plates 14 on both sides clamp and fix the side walls of the precast pipe gallery. The fixing block 16 is slid into the fixing groove 15, so that the fixing block 16 slides to the position of the L-shaped plate 14, so that the bolt on the fixing block 16 is inserted into the groove of the U-shaped plate 17 and the bolt is locked. At the same time, the hydraulic cylinder 25 is adjusted to drive the rotation of the support frame 21, so that the support wheel 23 contacts the ground. At this time, the support roller 24 contacts the bottom surface of the push arm 3. At this time, the support frame 21 and the push arm 3 form a large angle, thereby providing auxiliary support for the push arm 3.

[0040] When there is a misalignment between the precast pipe gallery to be assembled and the precast pipe gallery after assembly, the construction workers control the retraction of the translation hydraulic cylinder 11 on one side and the extension of the translation hydraulic cylinder 11 on the other side, causing the sliding arms 9 on both sides to translate to one side, driving the four L-shaped plates 14 to translate sequentially, thereby pushing the precast pipe gallery to be assembled to translate, so that the precast pipe gallery to be assembled is aligned with the precast pipe gallery after assembly; the jacking hydraulic cylinder 6 pushes the extension arm 4 to slide from the middle of the jacking arm 3, pushing the horizontal beam 5 to move, pushing the precast pipe gallery to be assembled closer to the precast pipe gallery after assembly, and maintaining the specified gap; the precast pipe galleries between When the gap is small, the horizontal beam 5 moves to the middle of the precast pipe gallery, and the translation hydraulic cylinder 11 pushes the sliding arm 9 out of the inside of the sliding groove 8, pushing the top support blocks 29 on both sides to squeeze the inner walls of the precast pipe gallery on both sides. The anti-slip groove 30 increases the friction between the precast pipe gallery and the top support block 29. The jacking hydraulic cylinder 6 pulls the extension arm 4 into the inside of the jacking arm 3, thereby pulling the precast pipe gallery outward and increasing the gap between the precast pipe galleries. This completes the translation and jacking work of the precast pipe gallery, reduces the difficulty of the construction workers' work, makes it easier for the workers to control the gap between the precast pipe galleries, and improves the construction quality of the pipe gallery tunnel.
