Description

Technical Field

[0001] This invention relates to the field of intermediate equipment technology for pipe jacking machines, specifically to a wedge-shaped intermediate structure and its usage method. Background Technology

[0002] A pipe jacking machine is a tunnel excavation device that uses the pipe jacking method. The intermediate chamber is an important piece of equipment for the pipe jacking machine. When the pipe jacking machine encounters insufficient jacking force or the jacking force exceeds the stress of the pipe section, the intermediate chamber needs to be activated. After the pipe jacking machine construction is completed, the hydraulic cylinder of the intermediate chamber often needs to be removed and the shell left in the tunnel as a permanent structure. The existing intermediate chamber structure is complex and not conducive to disassembly.

[0003] When the intermediate structure pushes the pipe jacking, it usually only relies on the thrust of the hydraulic cylinder to move the pipe. As the pipe advances, due to the accumulation of soil at the front end of the pipe, the resistance encountered by the intermediate structure gradually increases, which in turn gradually increases the load on the hydraulic cylinder, greatly reducing the service life of the hydraulic cylinder. At the same time, the existing intermediate structure can only push the front segment when pushing the pipe jacking, but cannot drive the rear segment forward, resulting in poor linkage effect.

[0004] Therefore, it is necessary to invent a wedge-shaped pipe jacking relay station structure and its usage method. Summary of the Invention

[0005] To address this, the present invention provides a wedge-shaped jacking pipe relay station structure and its usage method. The chuck is installed into the front segment by bolt connection, and the swivel device is installed into the rear segment by the cooperation of the electric telescopic rod and the chuck hole. When it is necessary to push the jacking pipe to move, the front segment can be displaced in two stages by the cooperation of the jacking and swivel assembly and the arc-shaped swivel groove, so as to solve the problems of complex disassembly and short service life of the existing relay station structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wedge-shaped jacking pipe relay station structure and its usage method, comprising a jacking device, a rear tube segment, and a front tube segment. The jacking device is located inside the rear tube segment, and the rear tube segment is used in conjunction with the front tube segment. The jacking device includes an outer cylinder, and a jacking assembly is provided at the front end of the outer cylinder. A jacking plate is connected to the front end of the jacking assembly. An arc-shaped pressure plate is fixedly installed on the outer side of the front end face of the jacking plate. Four sets of arc-shaped pressure plates are provided and distributed on the four sides of the front end of the jacking plate.

[0007] The top-spinning assembly includes a base sleeve, the end of which is fixedly connected to the front end face of the outer cylinder. A limiting groove is formed on the front side wall of the base sleeve. There are four sets of limiting grooves, and the included angle between each pair is 90°. A relay sleeve is slidably connected to the inner wall of the base sleeve. A right inclined surface and a left inclined surface are formed on all four sides of the front wall of the relay sleeve. The right inclined surface and the left inclined surface are symmetrically arranged. The right inclined surface and the left inclined surface on the same side are aligned with the limiting groove on that side. Triangular sliders are fixedly installed on the outer walls of the four sides of the front end of the relay sleeve. The triangular sliders are slidably connected to the corresponding limiting grooves.

[0008] The inner wall of the relay sleeve is slidably connected to a top shaft. A cross slot is provided at the center of the end face of the top shaft. An inclined top plate is fixedly installed on the front face of the top shaft. There are four sets of inclined top plates. The top shaft and the front face of the inclined top plate are fixedly connected to the rotary plate. The inclined surfaces at the ends of the four sets of inclined top plates are in close contact with the right inclined surface and the left inclined surface.

[0009] Preferably, the right and left inclined surfaces coincide with the top two inclined surfaces of the corresponding triangular sliders, and the end walls of two adjacent sets of triangular sliders are fixedly installed with the same connecting plate. A cylinder is fixedly installed on the top surface of the end of the base sleeve. Multiple sets of cylinders are provided and evenly distributed on the base sleeve, and the top output ends of the multiple sets of cylinders are fixedly connected to the connecting plate.

[0010] Preferably, a planetary gear mechanism is connected to the inner wall of the outer cylinder, and a cross-shaped insert is fixedly installed at the output end of the planetary gear mechanism. The cross-shaped insert is engaged with a cross slot and slidably connected to the top shaft. A motor is fixedly installed on the inner wall of the end of the outer cylinder, and the output end of the motor is fixedly connected to the input end of the planetary gear mechanism.

[0011] Preferably, the rear tube segment is slidably connected to the front tube segment, and the inner wall of the rear tube segment end is provided with a locking hole. There are four sets of locking holes evenly distributed on the inner wall of the rear tube segment. A connecting seat is provided in the middle of the rear tube segment end. Electric telescopic rods are fixedly installed on the outer walls of the four sides of the connecting seat. The output ends of the four sets of electric telescopic rods are respectively engaged with the four sets of locking holes, and the connecting seat is fixedly connected to the rear tube segment. A hydraulic cylinder is fixedly installed on the front end face of the connecting seat, and the output end of the hydraulic cylinder is fixedly connected to the end wall of the outer cylinder.

[0012] Preferably, a chuck is fixedly installed on the inner wall of the front end of the front tube segment by bolts, and a rotating cylinder is fixedly installed on the inner wall of the chuck. An arc-shaped rotating groove is opened on the end wall of the rotating cylinder. There are four sets of arc-shaped rotating grooves, which are respectively engaged with four sets of arc-shaped pressure plates. A buffer zone is opened at the top of the arc-shaped rotating groove.

[0013] Preferably, a method for using a wedge-shaped jacking pipe relay station structure further includes the following specific operating steps:

[0014] S1: Install the chuck into the front tube segment with bolts, and at the same time, insert the four sets of electric telescopic rods into the chuck holes to complete the installation of the relay station structure. After the relay station is installed between the two sets of top tubes, drive the hydraulic cylinder to make its output shaft push the spinning device forward, so that the arc-shaped pressure plate and the arc-shaped spinning groove are fully engaged. At this time, the relay station is in the initial state.

[0015] S2: When it is necessary to push the front-end jacking pipe to move, multiple sets of cylinders are driven to push the connecting plate with their output shafts, thereby driving the relay sleeve to slide in the base sleeve. Under the limiting action of the limiting slide groove, the triangular slider pushes the inclined jacking plate to slide outward, thereby pushing the rotary plate and chuck to move forward, so that the front pipe segment moves forward and thus pushes the front-end jacking pipe to make a certain displacement.

[0016] S3: When the cylinder output reaches the extreme position, the inclined top plate is completely separated from the limit slide groove. At this time, the drive motor drives the planetary gear mechanism to work, which causes the cross shaft connected to the planetary gear mechanism to rotate. The cross shaft drives the top shaft to rotate, causing the inclined top plate at the front end of the top shaft to rotate on the left inclined surface and the end face of the intermediate sleeve. At the same time, it drives the rotating plate to rotate, causing the arc-shaped pressure plate at the front end of the rotating plate to misalign with the arc-shaped rotating groove, thereby pushing the rotating cylinder and the chuck to move, causing the front tube segment to move forward, thereby pushing the front top tube to perform a second displacement.

[0017] S4: When the arc-shaped pressure plate moves to the buffer zone, the arc-shaped pressure plate and the arc-shaped swivel groove can re-engage, and the inclined top plate rotates exactly 90°. At this time, the front tube segment reaches the maximum displacement. Then, the arc-shaped pressure plate and the arc-shaped swivel groove are re-engaged by the secondary drive hydraulic cylinder, that is, the arc-shaped pressure plate and the arc-shaped swivel groove are in the initial state. At this time, the arc-shaped pressure plate is locked onto the end wall of the arc-shaped swivel groove by the reverse motor. At the same time, the reverse drive cylinder and hydraulic cylinder make the rear tube segment move forward so that the rear tube segment re-engages with the front tube segment. At the same time, the relay returns to the initial state.

[0018] S5: After the work is completed, retract the four sets of electric telescopic rods so that their output ends can be dislodged from the chuck holes. At the same time, remove the chuck from the front tube segment using bolts, thereby removing the internal structure of the relay room and completing the disassembly of the relay room structure.

[0019] The beneficial effects of this invention are:

[0020] 1. When it is necessary to push the front-end jacking pipe to move, multiple sets of cylinders are driven to push the connecting plate with their output shafts, thereby driving the relay sleeve to slide inside the base sleeve. Under the limiting action of the limiting groove, the triangular slider pushes the inclined top plate to slide outward, thereby pushing the rotary plate and chuck to move forward, causing the front tube segment to move forward and thus pushing the front-end jacking pipe to make a displacement. When the cylinder output reaches the extreme position, the inclined top plate is completely separated from the limiting groove. At this time, the drive motor drives the planetary gear mechanism to work with its output shaft, thereby causing the cross shaft connected to the planetary gear mechanism to rotate. At this time, the cross shaft drives the top shaft to rotate, causing the inclined top plate at the front end of the top shaft to rotate on the left inclined surface and the end face of the relay sleeve. At the same time, it drives the rotary plate to rotate, causing the arc-shaped pressure plate at the front end of the rotary plate to misalign with the arc-shaped rotary groove, thereby pushing the receiving cylinder and chuck to move, causing the front tube segment to move forward and thus pushing the front-end jacking pipe to make a second displacement.

[0021] 2. When the arc-shaped pressure plate moves to the buffer zone, the arc-shaped pressure plate and the arc-shaped swivel groove can re-engage, and the inclined top plate rotates exactly 90°. At this time, the front tube segment reaches the maximum displacement. Then, the arc-shaped pressure plate and the arc-shaped swivel groove are re-engaged by the secondary drive hydraulic cylinder, that is, the arc-shaped pressure plate and the arc-shaped swivel groove are in the initial state. At this time, the arc-shaped pressure plate is locked onto the end wall of the arc-shaped swivel groove by the reverse motor. At the same time, the reverse drive cylinder and hydraulic cylinder make the rear tube segment move forward so that the rear tube segment re-engages with the front tube segment. At the same time, the intermediate station returns to the initial state.

[0022] 3. Install the chuck into the front tube segment using bolts, and simultaneously engage the four sets of electric telescopic rods into the locking holes to complete the installation of the relay station structure. After installing the relay station between the two sets of jacking pipes, drive the hydraulic cylinder to push the swivel device forward with its output shaft, so that the arc-shaped pressure plate and the arc-shaped swivel groove are fully engaged. At this time, the relay station is in its initial state. After the work is completed, retract the four sets of electric telescopic rods so that their output ends are disengaged from the locking holes. At the same time, remove the chuck from the front tube segment using bolts to remove the internal structure of the relay station, thus completing the disassembly of the relay station structure.

Detailed Implementation

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] See attached document Figure 1-12 The present invention provides a wedge-shaped jacking pipe relay station structure and usage method, including a jacking device 100, a rear tube 200 and a front tube 300. The jacking device 100 is located inside the rear tube 200. The rear tube 200 and the front tube 300 are used in conjunction. The jacking device 100 includes an outer cylinder 140. A jacking assembly 110 is provided at the front end of the outer cylinder 140. A jacking plate 150 is connected to the front end of the jacking assembly 110. An arc-shaped pressure plate 151 is fixedly installed on the outer side of the front end face of the jacking plate 150. There are four sets of arc-shaped pressure plates 151 distributed on the four sides of the front end of the jacking plate 150.

[0038] The top-spinning assembly 110 includes a base sleeve 111, the end of which is fixedly connected to the front end face of the outer cylinder 140. A limiting groove 112 is formed on the front side wall of the base sleeve 111. Four sets of limiting grooves 112 are provided, with an included angle of 90° between each pair. A relay sleeve 113 is slidably connected to the inner wall of the base sleeve 111. A right inclined surface 114 and a left inclined surface 115 are formed on all four sides of the front wall of the relay sleeve 113. The right inclined surface 114 and the left inclined surface 115 are symmetrically arranged. The right inclined surface 114 and the left inclined surface 115 on the same side are aligned with the limiting groove 112 on that side. Triangular sliders 116 are fixedly installed on the four outer walls of the front end of the cylinder 113. The triangular sliders 116 are slidably connected to the corresponding limiting grooves 112. Specifically, when it is necessary to push the front end jacking pipe to move, multiple sets of cylinders 130 are driven to push the connecting plate 117 with their output shafts, thereby driving the relay sleeve 113 to slide in the base sleeve 111. Under the limiting action of the limiting grooves 112, the triangular sliders 116 push the inclined jacking plate 120 to slide outward, thereby pushing the rotating plate 150 and the chuck 310 to move forward, so that the front pipe segment 300 moves forward, thereby pushing the front end jacking pipe to make a certain displacement.

[0039] A top shaft 118 is slidably connected to the inner wall of the relay sleeve 113. A cross slot 119 is provided at the center of the end face of the top shaft 118. An inclined top plate 120 is fixedly installed on the front face of the top shaft 118. There are four sets of inclined top plates 120. The top shaft 118 and the front face of the inclined top plate 120 are fixedly connected to the rotary plate 150. The inclined surfaces at the ends of the four sets of inclined top plates 120 are in close contact with the right inclined surface 114 and the left inclined surface 115.

[0040] Furthermore, the right inclined surface 114 and the left inclined surface 115 respectively coincide with the top two inclined surfaces of the corresponding triangular sliders 116. The end walls of two adjacent sets of triangular sliders 116 are fixedly installed with the same connecting plate 117. The top surface of the end of the base sleeve 111 is fixedly installed with a cylinder 130. Multiple sets of cylinders 130 are provided and evenly distributed on the base sleeve 111. The top output ends of multiple sets of cylinders 130 are fixedly connected to the connecting plate 117. The inner wall of the outer cylinder 140 is connected to a planetary gear mechanism 141. The output end of the planetary gear mechanism 141 is fixedly installed with a cross-shaped insert shaft 142. The cross-shaped insert shaft 142 is engaged with the cross slot 119 and slidably connected to the top shaft 118. The inner wall of the end of the outer cylinder 140 is fixedly installed with a motor 143, and the output end of the motor 143 is fixedly connected to the input end of the planetary gear mechanism 141. Specifically, when the cylinder 130 outputs to the extreme position, the inclined top plate 120 is exactly completely aligned with the limit. When the sliding groove 112 separates, the drive motor 143 drives the planetary gear mechanism 141 to work, thereby causing the cross-shaped insert shaft 142 connected to the planetary gear mechanism 141 to rotate. At this time, the cross-shaped insert shaft 142 drives the top shaft 118 to rotate, causing the inclined top plate 120 at the front end of the top shaft 118 to rotate on the left inclined surface 115 and the end face of the relay sleeve 113. At the same time, it drives the rotating plate 150 to rotate, causing the arc-shaped pressure plate 151 at the front end of the rotating plate 150 to misalign with the arc-shaped rotating groove 321, thereby pushing the rotating cylinder 320 and the chuck 310 to move, causing the front tube segment 300 to move forward, thereby pushing the front top tube to perform a two-stage displacement. When the arc-shaped pressure plate 151 moves to the buffer zone 322, the arc-shaped pressure plate 151 and the arc-shaped rotating groove 321 can re-mesh, and the inclined top plate 120 rotates exactly 90°. At this time, the front tube segment 300 reaches the maximum displacement.

[0041] Furthermore, the rear segment 200 is slidably connected to the front segment 300. The inner wall of the rear segment 200's end has four sets of locking holes 210 evenly distributed on its inner wall. A connecting seat 220 is located at the middle of the rear segment 200's end. Electric telescopic rods 221 are fixedly installed on the four outer walls of the connecting seat 220. The output ends of the four sets of electric telescopic rods 221 are respectively engaged with the four sets of locking holes 210, and the connecting seat 220 is fixedly connected to the rear segment 200. A hydraulic cylinder 222 is fixedly installed on the front end face of the connecting seat 220. The output end of the hydraulic cylinder 222 is fixedly connected to the end wall of the outer cylinder 140. A chuck 310 is fixedly installed on the inner wall of the front end of the front tube segment 300 by bolts. The chuck 310 and the front tube segment 300 are detachable. A rotating cylinder 320 is fixedly installed on the inner wall of the chuck 310. An arc-shaped rotating groove 321 is opened on the end wall of the rotating cylinder 320. There are four sets of arc-shaped rotating grooves 321, which are respectively connected to... Four sets of arc-shaped pressure plates 151 are engaged. A buffer zone 322 is provided at the top of the arc-shaped swivel groove 321. The buffer zone 322 can serve as a transition zone for the arc-shaped pressure plates 151, allowing them to move smoothly into the next set of arc-shaped swivel grooves 321. Specifically, the chuck 310 is installed into the front tube segment 300 by bolts, and at the same time, the four sets of electric telescopic rods 221 are inserted into the locking holes 210, thereby completing the installation of the relay station structure. After the relay station is installed between the two sets of top tubes, the hydraulic cylinder 222 is driven so that its output shaft pushes the swivel device 100 forward, so that the arc-shaped pressure plates 151 and the arc-shaped swivel grooves 321 are fully engaged. At this time, the relay station is in its initial state. After the work is completed, the four sets of electric telescopic rods 221 are retracted, and their output ends are disengaged from the locking holes 210. At the same time, the chuck 310 is removed from the front tube segment 300 by bolts, thereby removing the internal structure of the relay station and completing the disassembly of the relay station structure.

[0042] The process of using this invention is as follows: Those skilled in the art install the chuck 310 into the front tube 300 with bolts, and at the same time, insert the four sets of electric telescopic rods 221 into the locking holes 210, thereby completing the installation of the relay station structure. After the relay station is installed between the two sets of top tubes, the hydraulic cylinder 222 is driven to push the spinning device 100 forward with its output shaft, so that the arc-shaped pressure plate 151 and the arc-shaped swivel groove 321 are fully engaged. At this time, the relay station is in the initial state. After the work is completed, the four sets of electric telescopic rods 221 are retracted, and their output ends are dislodged from the locking holes 210. At the same time, the chuck 310 is removed from the front tube 300 with bolts, thereby removing the internal structure of the relay station and completing the disassembly of the relay station structure.

[0043] When it is necessary to push the front-end jacking pipe to move, multiple sets of cylinders 130 are driven to push the connecting plate 117 with their output shafts, thereby driving the relay sleeve 113 to slide in the base sleeve 111. Under the limiting action of the limiting slide groove 112, the triangular slider 116 pushes the inclined jacking plate 120 to slide outward, thereby pushing the rotary plate 150 and the chuck 310 to move forward, so that the front pipe segment 300 moves forward, thereby pushing the front-end jacking pipe to make a certain displacement.

[0044] When cylinder 130 outputs to its extreme position, the inclined top plate 120 is completely separated from the limiting slide groove 112. At this time, the drive motor 143 drives the planetary gear mechanism 141 to work, thereby causing the cross-shaped insert shaft 142 connected to the planetary gear mechanism 141 to rotate. The cross-shaped insert shaft 142 drives the top shaft 118 to rotate, causing the inclined top plate 120 at the front end of the top shaft 118 to rotate on the left inclined surface 115 and the end face of the relay sleeve 113. At the same time, it drives the rotating plate 150 to rotate, causing the arc-shaped pressure plate 151 at the front end of the rotating plate 150 to misalign with the arc-shaped rotating groove 321, thereby pushing the rotating cylinder 320 and the chuck 310 to move, causing the front tube segment 300 to move forward, thereby pushing the front top tube to move. In the second stage of displacement, when the arc-shaped pressure plate 151 moves onto the buffer zone 322, the arc-shaped pressure plate 151 and the arc-shaped swivel groove 321 can re-engage, and the inclined top plate 120 rotates exactly 90°. At this time, the front tube segment 300 reaches its maximum displacement. Subsequently, the arc-shaped pressure plate 151 and the arc-shaped swivel groove 321 are re-engaged through the secondary drive hydraulic cylinder 222, that is, the arc-shaped pressure plate 151 and the arc-shaped swivel groove 321 are in the initial state. At this time, the arc-shaped pressure plate 151 is locked onto the end wall of the arc-shaped swivel groove 321 by the reverse motor 143. At the same time, the reverse drive cylinder 130 and the hydraulic cylinder 222 cause the rear tube segment 200 to move forward, so that the rear tube segment 200 and the front tube segment 300 re-engage, and the intermediate section returns to the initial state.

[0045] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.

The output ends of the four sets of electric telescopic rods (221) are respectively engaged with the four sets of locking holes (210), and the connecting seat (220) is fixedly connected to the rear tube segment (200). A hydraulic cylinder (222) is fixedly installed on the front end face of the connecting seat (220). The output end of the hydraulic cylinder (222) is fixedly connected to the end wall of the outer cylinder (140).

5. The wedge-shaped jacking pipe relay station structure according to claim 4, characterized in that: A chuck (310) is fixedly installed on the inner wall of the front end of the front tube segment (300) by bolts. A rotating cylinder (320) is fixedly installed on the inner wall of the chuck (310). An arc-shaped rotating groove (321) is opened on the end wall of the rotating cylinder (320). There are four sets of arc-shaped rotating grooves (321) that are respectively engaged with four sets of arc-shaped pressure plates (151). A buffer zone (322) is opened at the top of the arc-shaped rotating groove (321).

6. The method of using the wedge-shaped jacking pipe relay station structure according to claim 5, characterized in that: The specific operating steps are as follows: S1: Install the chuck (310) into the front tube segment (300) by bolts, and at the same time, insert the four sets of electric telescopic rods (221) into the chuck holes (210) to complete the installation of the relay station structure. After the relay station is installed between the two sets of top tubes, drive the hydraulic cylinder (222) to make its output shaft push the spinning device (100) forward, so that the arc-shaped pressure plate (151) and the arc-shaped swirl groove (321) are fully engaged. At this time, the relay station is in the initial state. S2: When it is necessary to push the front end jacking pipe to move, multiple sets of cylinders (130) are driven to push the connecting plate (117) with their output shafts, thereby driving the relay sleeve (113) to slide in the base sleeve (111). Under the limiting action of the limiting groove (112), the triangular slider (116) pushes the inclined top plate (120) to slide outward, thereby pushing the rotary plate (150) and chuck (310) to move forward, so that the front pipe segment (300) moves forward, thereby pushing the front end jacking pipe to make a displacement. S3: When the cylinder (130) outputs to the extreme position, the inclined top plate (120) is completely separated from the limit slide (112). At this time, the drive motor (143) drives the planetary gear mechanism (141) to work, thereby causing the cross-shaped insert shaft (142) connected to the planetary gear mechanism (141) to rotate. At this time, the cross-shaped insert shaft (142) drives the top shaft (118) to rotate, causing the inclined top plate (120) at the front end of the top shaft (118) to rotate on the left inclined surface (115) and the end face of the relay sleeve (113), and at the same time, it drives the rotating plate (150) to rotate, causing the arc-shaped pressure plate (151) at the front end of the rotating plate (150) to be misaligned with the arc-shaped rotating groove (321), thereby pushing the rotating cylinder (320) and the chuck (310) to move, causing the front tube segment (300) to move forward, thereby pushing the front top tube to perform a second displacement. S4: When the arc-shaped pressure plate (151) moves to the buffer zone (322), the arc-shaped pressure plate (151) and the arc-shaped swivel groove (321) can re-engage, and the inclined top plate (120) rotates 90°. At this time, the front tube segment (300) reaches the maximum displacement. After that, the arc-shaped pressure plate (151) and the arc-shaped swivel groove (321) are re-engaged by the secondary drive hydraulic cylinder (222). That is, the arc-shaped pressure plate (151) and the arc-shaped swivel groove (321) are in the initial state. At this time, the arc-shaped pressure plate (151) is locked on the end wall of the arc-shaped swivel groove (321) by the reverse motor (143). At the same time, the reverse drive cylinder (130) and the hydraulic cylinder (222) are reversed, so that the rear tube segment (200) moves forward and re-engages with the front tube segment (300). At the same time, the intermediate station returns to the initial state. S5: After the work is completed, retract the four sets of electric telescopic rods (221) so that their output ends are removed from the chuck holes (210). At the same time, remove the chuck (310) from the front tube segment (300) by bolts, thereby removing the internal structure of the relay room and completing the disassembly of the relay room structure.
