Description

Technical Field

[0001] This utility model belongs to the field of pipeline laying technology, specifically a pipeline laying jacking device. Background Technology

[0002] With the acceleration of old city renovation, the number of small-diameter pipeline laying projects is increasing. The construction methods are mainly trenching and trenchless construction. However, traditional trenching construction has many drawbacks such as road damage, traffic disruption, and environmental pollution. Small-diameter pipe jacking construction technology is a good alternative for laying or repairing old pipelines. When laying pipelines, trenches are dug at both ends of the pipeline. A directional drilling device is set on one side to drill holes for the pipeline pre-buried route. Then, the holes are enlarged and the pipeline to be laid is jacked in to achieve pipeline laying.

[0003] Existing pipeline jacking devices require digging jacking trenches at both ends of the pipeline. The bottom of these trenches is usually soft, wet soil, which makes it easy for the support height to change during use, affecting the jacking angle of the pipeline. In addition, conventional horizontal hydraulic propulsion devices require digging large trenches, resulting in a large working area and significant damage to roads. Therefore, a new pipeline jacking device is proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes a pipe-laying jacking device. This device addresses the issues of excavating trenches at both ends of the pipe jacking process, where the bottom of these trenches is typically soft, wet soil. During use, the support height of these trenches is easily altered, potentially affecting the jacking angle of the pipe. Furthermore, conventional horizontal hydraulic propulsion devices require excavating large trenches, resulting in a large working area and significant road damage. Through a lifting structure, the horizontal height of the supporting plates at both ends can be adjusted to freely change the pipe's entry direction, enabling more accurate jacking and ensuring the pipe is jacked along the pre-drilled hole for successful pipe laying. Adjusting the longitudinal hydraulic propulsion to vertical propulsion reduces the area of ​​trenches excavated at both ends of the pipe laying process, minimizing earthwork and damage to the construction road surface.

[0005] The technical solution adopted by this utility model to solve its technical problem is a pipe laying jacking device, including a supporting base plate, and a supporting vertical plate is vertically fixed at one end of the supporting base plate;

[0006] The lifting structure has two lifting structures slidably installed on the top side of the supporting base plate, and the top of the two lifting structures is provided with pipes;

[0007] The supporting base plate has a sliding groove inside. The lifting structure includes a second slider, which is slidably disposed in the sliding groove. The supporting cross plate is disposed above the second slider. The bottom side of the supporting cross plate is provided with a slide rail, and the first slider is symmetrically slidably mounted on the slide rail.

[0008] A bidirectional lead screw is provided, with mounting brackets fixed to the bottom sides of both ends of the support cross plate, and a bidirectional lead screw rotatably mounted between the two mounting brackets. A screw is provided inside the first slider, and the bidirectional lead screw rotatably passes through the first slider.

[0009] The lifting rod has a fixed seat between the bottom side of the first slider and the top side of the second slider, and the lifting rod is connected between the two fixed seats. The bidirectional lead screw is a bidirectional screw rod, and a rotating disk is installed at one end of the bidirectional lead screw. A handle is installed on the rotating disk to facilitate the adjustment of the height of the lifting structure.

[0010] Preferably, a baffle is fixed to the top side of one of the lifting structures, and a vertically downward sliding hole is opened in the middle of the supporting vertical plate. A sliding plate is slidably arranged in the sliding hole, and the sliding plate is fixed to one side of the push plate. A connecting seat is provided on one side of the baffle and the bottom of the sliding plate, and a push rod is connected and installed between the two connecting seats.

[0011] Preferably, a hydraulic cylinder mounting base is fixed to one side of the top of the support vertical plate, a hydraulic cylinder is installed on the bottom side of the hydraulic cylinder mounting base, and a push plate is connected to the bottom of the working end of the hydraulic cylinder.

[0012] Preferably, the top side of the supporting horizontal plate is provided with a support seat, and the two support seats are arranged in a V-shape. By rotating the rotating screw, the V-shaped frame can be pushed downward to clamp and fix one end of the pipe, which can ensure the stability of the force during the pipe pushing process and avoid tilting and deviation, thus affecting the jacking effect of the pipe.

[0013] Preferably, a fixing plate is fixed to the top of the other side of the baffle, and a screw hole is provided inside the fixing plate. A rotating screw is rotatably installed in the screw hole, and a V-shaped bracket is rotatably connected to the bottom end of the rotating screw.

[0014] Preferably, a monitoring structure is installed on the other side of the baffle. The monitoring structure includes a locking screw, which is fixed on the other side of the baffle. A sliding plate is slidably disposed on the locking screw, and a locking nut is rotatably disposed on the locking screw. A laser head is installed at one end of the sliding plate. The pipe is erected above two support seats, and the V-shaped frame is disposed above the pipe. By rotating and loosening the locking nut, the sliding plate can be allowed to slide freely. The laser head is used for point calibration. After the point is determined, during the pipe jacking process, the accuracy and stability of the pipe advancement can be accurately determined by judging the irradiation point of the laser head.

[0015] The advantages of this utility model are:

[0016] This utility model is used when laying pipes by pushing them in. During the rotation of the bidirectional screw, the two first sliders at the bottom of the support plate move relative to each other or in opposite directions. This allows the horizontal height of the support plate to be adjusted. By adjusting the horizontal height of the support plate at both ends, the direction of the pipe's entry hole can be freely adjusted for more accurate insertion. This ensures that the pipe is pushed in along the pre-drilled hole, thus achieving the laying of the pipe.

[0017] During pipeline advancement, the hydraulic cylinder pressurizes the push plate downwards, and with the help of the push rod, it pushes the lifting structure to move horizontally along the slide groove of the support base plate. Under the pressure of the side of the baffle, the pipeline is advanced. Adjusting the longitudinal hydraulic propulsion to vertical advancement can reduce the area of ​​trenching at both ends of the pipeline laying, reduce earthwork, and reduce damage to the construction road surface.

[0029] One of the lifting structures 13 has a baffle 8 fixed on its top side. A vertically downward sliding hole is opened in the middle of the supporting vertical plate 2. A sliding plate 14 is slidably arranged in the sliding hole. The sliding plate 14 is fixed to one side of the push plate 5.

[0030] A connecting seat is provided on one side of the baffle 8 and the bottom of the slide plate 14 respectively, and a push rod 6 is connected and installed between the two connecting seats;

[0031] The second slider 138 is provided in the interior of the supporting base plate 1. The lifting structure 13 includes the second slider 138, which is slidably disposed in the sliding groove. The supporting horizontal plate 132 is disposed above the second slider 138. The bottom side of the supporting horizontal plate 132 is provided with a slide rail 135, and the first slider 136 is symmetrically slidably mounted on the slide rail 135.

[0032] The bidirectional lead screw 133 is provided. Mounting brackets are fixed to the bottom sides of both ends of the support plate 132. The bidirectional lead screw 133 is rotatably installed between the two mounting brackets. A screw is provided in the first slider 136. The bidirectional lead screw 133 is rotatably installed through the first slider 136.

[0033] The lifting rod 137 is provided with a fixed seat between the bottom side of the first slider 136 and the top side of the second slider 138, and the lifting rod 137 is connected between the two fixed seats.

[0034] The bidirectional lead screw 133 is a bidirectional screw, and a rotating disk 134 is installed at one end of the bidirectional lead screw 133. A handle is installed on the rotating disk 134. A support seat 131 is provided on the top side of the support plate 132. The two support seats 131 are arranged in a V-shape. During operation, rotating the rotating disk 134 can drive the bidirectional lead screw 133 to rotate. During the rotation of the bidirectional lead screw 133, the two first sliders 136 at the bottom of the support plate 132 can move relative to each other or in opposite directions, which can adjust the horizontal height of the support plate 132. By adjusting the horizontal height of the support plate 132 at both ends, the inlet direction of the pipe 12 can be freely adjusted so as to more accurately insert the pipe into the hole and ensure that the pipe is inserted along the pre-drilled hole to realize the laying of the pipe.

[0035] The sliding surface of the second slider 138 is in close contact with the inner wall of the groove of the inner wall of the support base plate 1, which can provide sufficient friction to prevent the adjusted lifting structure 13 from moving back and forth. The lifting structure 13, which is equipped with baffle 8, performs the pushing operation of the pipe 12 under hydraulic thrust. There is also sufficient friction between the two-way screw 133 and the slide rail 135 to prevent the height of the support plate 132 from changing, which can help to achieve the advancement of the pipe 12 with the angle of entry of movement.

[0036] A fixing plate 10 is fixed to the top of the other side of the baffle 8. The fixing plate 10 has a screw hole inside, and a rotating screw 9 is rotatably installed in the screw hole. A V-shaped frame 11 is rotatably connected to the bottom end of the rotating screw 9. During operation, by rotating the rotating screw 9, the V-shaped frame 11 can be pushed downward to clamp and fix one end of the pipe 12, which can ensure that the pipe 12 is stable under force during the advancement process and avoid tilting and deviation, thus affecting the jacking effect of the pipe 12.

[0037] A monitoring structure 7 is installed on the other side of the baffle 8. The monitoring structure 7 includes a locking screw 72. The locking screw 72 is fixed on the other side of the baffle 8. A sliding plate 71 is slidably arranged on the locking screw 72. A locking nut 73 is rotatably installed on the locking screw 72. A laser head 74 is installed at one end of the sliding plate 71. The pipe 12 is erected above two support seats 131. The V-shaped frame 11 is set above the pipe 12. During operation, when the pipe 12 is pushed forward, the sliding plate 71 can be freely slid by rotating and loosening the locking nut 73. The laser head 74 is used for point calibration. After the point is determined, during the pipe 12 pushing forward, the irradiation point of the laser head 74 can be judged to accurately determine whether the pipe 12 is pushed forward accurately and stably.

[0038] With the acceleration of urban renewal, the number of small-diameter pipeline laying projects is increasing. The main construction methods are trenching and trenchless construction. However, traditional trenching construction is increasingly unsuitable for green and "non-invasive" construction due to numerous drawbacks such as road damage, traffic disruption, and environmental pollution. This has prompted construction companies to research and develop new alternative methods. Small-diameter pipe jacking is a good alternative method for laying or repairing old pipelines. During pipeline laying, trenches are dug at both ends of the pipeline. A directional drilling device is installed on one side to drill holes for the pre-buried pipeline route. Then, the holes are enlarged before the pipe is jacked in, thus laying the pipeline.

[0039] The pipe 12 is placed on the lifting structure 13 of the support base plate 1. When positioning the pipe, the rotating disk 134 can drive the bidirectional screw 133 to rotate. During the rotation of the bidirectional screw 133, the two first sliders 136 at the bottom of the support horizontal plate 132 can move relative to each other or in opposite directions, which can adjust the horizontal height of the support horizontal plate 132. By adjusting the horizontal height of the support horizontal plate 132 at both ends, the insertion direction of the pipe 12 can be freely adjusted so as to more accurately insert the pipe into the hole and ensure that the pipe is inserted along the previously opened hole to realize the laying of the pipe.

[0040] The sliding surface of the second slider 138 is in close contact with the inner wall of the groove of the inner wall of the support base plate 1, which can provide sufficient friction to prevent the adjusted lifting structure 13 from moving back and forth. The lifting structure 13 with baffle 8 installed performs the pushing operation of pipe 12 under hydraulic thrust. There is also sufficient friction between the two-way screw 133 and the slide rail 135 to prevent the height of the support plate 132 from changing, which can help to achieve the advancement of pipe 12 with the angle of entry of movement.

[0041] During the pipeline advancement process, by rotating the screw 9, the V-shaped frame 11 can be pushed downward to clamp and fix one end of the pipeline 12, ensuring the stability of the force on the pipeline 12 during advancement and avoiding tilting or deviation, which would affect the jacking effect of the pipeline 12.

[0042] During the jacking of pipe 12, the sliding plate 71 can be freely slid by rotating and loosening the locking nut 73. The laser head 74 is used for point calibration. After the point is determined, during the jacking of pipe 12, the irradiation point of the laser head 74 can be judged to accurately determine whether the advancement of pipe 12 is accurate and stable.

[0043] When the pipeline is advanced, the hydraulic cylinder 4 pressurizes the push plate 5 to move downward. With the cooperation of the push rod 6, the lifting structure 13 can be pushed to move horizontally along the slide of the support base plate 1. Under the pressure of the side of the baffle 8, the pipeline 12 is pushed forward. Adjusting the longitudinal hydraulic propulsion to vertical propulsion can reduce the area of ​​trenching at both ends of the pipeline laying, reduce earthwork, and reduce damage to the construction road surface.

[0044] In the description of this specification, the basic principles, main features and advantages of this utility model have been shown and described above. For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
