Description

Technical Field

[0001] The present application relates to the technical field of underground pipeline construction equipment, and in particular to a relay room for pipe jacking construction that is easy to disassemble and assemble. Background Art

[0002] In long-distance pipe jacking construction, as the jacking length increases, the axial resistance of the pipeline gradually increases. When the resistance exceeds the set value of the pipe jacking equipment or the bearing capacity of the pipe structure, it will cause the pipeline to be difficult to jack or the pipe to break. In order to ensure the normal progress of the construction, the relay room method is usually used for construction, that is, a relay room is set up in the middle of the long-distance pipeline, and the pipeline is jacked in sections through the relay room.

[0003] The relay room mainly includes a cylinder barrel and a hydraulic cylinder arranged on the inner wall of the cylinder barrel, and the pipeline is pushed forward by the hydraulic cylinder. For example, a relay room is disclosed in the patent document with publication number CN115853531A. It mainly includes a first shell and a second shell, and the first shell is arranged outside the second shell. A hydraulic cylinder is arranged on the inner wall of the second shell through a clamp. The two ends of the hydraulic cylinder are respectively connected to the first shell and the second shell. The expansion and contraction of the hydraulic cylinder can drive the first shell and the second shell to slide relative to each other to achieve pipe jacking.

[0004] After the pipe jacking construction is completed, the hydraulic cylinder is disassembled, and the first shell and the second shell are left in the tunnel and filled with concrete to complete the construction of the underground pipeline. In the related art, the disassembly of the hydraulic cylinder usually requires multiple workers to cooperate with each other to disassemble the hydraulic cylinder, and the workers need to disassemble the clamps multiple times. This process has a heavy labor burden on the workers and takes a long time, which is not conducive to improving the construction efficiency. Summary of the invention

[0005] In order to improve the work efficiency of pipe jacking construction, the present application provides a relay room for pipe jacking construction that is easy to disassemble and assemble.

[0006] The present application provides a relay room for pipe jacking construction that is easy to disassemble and assemble, which adopts the following technical solution:

[0007] A relay room for pipe jacking construction that is easy to disassemble and assemble, comprises an inner cylinder and an outer cylinder sleeved on the outside of the inner cylinder, a hydraulic cylinder is also arranged inside the inner cylinder, and also comprises a quick locking assembly arranged on the hydraulic cylinder, a moving assembly that can move inside the pipe, and a telescopic structure installed on the moving assembly, wherein the quick locking assembly comprises two locking blocks slidably connected to the hydraulic cylinder, locking grooves are correspondingly opened on the inner cylinder, the locking blocks are inserted into the locking grooves, and sliding the locking blocks can drive the locking blocks to disengage from the locking grooves, one end of the telescopic structure is connected to the hydraulic cylinder, and the other end is connected to the moving assembly, and the telescopic structure can drive the hydraulic cylinder to move radially along the inner cylinder.

[0008] By adopting the above technical solution, when the relay room is not in use, the telescopic structure is in a retracted state. At this time, the hydraulic cylinder is fixed to the mobile assembly through the telescopic structure, and the mobile assembly drives the hydraulic cylinder to move to the specified position in the relay room, and multiple hydraulic cylinders are evenly spaced around the axis of the inner cylinder. Subsequently, by controlling the operation of the telescopic structure, the hydraulic cylinder can be driven to approach the inner wall of the inner cylinder along the radial direction of the inner cylinder. After the hydraulic cylinder reaches the specified position, the locking block is inserted into the locking groove to limit the hydraulic cylinder, thereby realizing the rapid installation of the hydraulic cylinder. Similarly, when disassembling the hydraulic cylinder, the locking block is moved to disengage it from the locking groove, and the hydraulic cylinder is driven to approach the mobile assembly through the telescopic structure, thereby realizing the rapid disassembly of the hydraulic cylinder.

[0009] Optionally, the quick locking assembly also includes a mounting plate, and the hydraulic cylinder and the locking block are both mounted on the plate; two locking blocks are provided and are located near the two ends of the hydraulic cylinder; a driving assembly for driving the locking block to move is provided on the mounting plate, and the driving assembly includes two driving blocks corresponding to the locking blocks, and the driving block is slid, and the driving block can drive the locking block to move after abutting against the locking block.

[0010] By adopting the above technical solution, a mounting plate is provided to facilitate the installation of the locking block and the installation of the drive assembly. Two locking blocks are provided and the locking blocks are driven to move by the drive block, which facilitates the staff to adjust the position of the locking block.

[0011] Optionally, mounting grooves are provided on the inner tube corresponding to the two ends of the hydraulic cylinder body, and the two ends of the hydraulic cylinder body are inserted into the mounting grooves. The mounting groove is provided with an opening on the side close to the axis of the inner tube, and the hydraulic cylinder can detach from the mounting groove by moving radially along the inner tube.

[0012] By adopting the above technical solution, a mounting groove is provided to further limit the positions of both ends of the hydraulic cylinder, thereby further improving the stability of the hydraulic cylinder after installation.

[0013] Optionally, the two driving blocks are located between two groups of locking blocks, and when the two driving blocks are away from each other, they can drive the locking blocks to be inserted into the locking grooves; the telescopic structure includes two rotating rods respectively rotatably connected to the two driving blocks, the two rotating rods are rotatably connected to each other, and the end of the rotating rod away from the driving block is detachably connected to the moving component.

[0014] By adopting the above technical solution, when the driving block moves, it drives the two rotating rods connected to each other to rotate, and the rotation of the rotating rods can drive the hydraulic cylinder to move. At the same time, one driving block corresponds to a group of locking blocks. When the two driving blocks are away from each other, they can abut against the locking blocks, driving the locking blocks to be inserted into the locking grooves. During the actual construction process, the hydraulic cylinder is installed on the mobile component, the two driving blocks are close to each other, the telescopic structure is extended, and the hydraulic cylinder is placed in the installation groove. The telescopic structure is then disassembled from the mobile component. At this time, the telescopic structure contracts to reduce the space occupied by the telescopic structure. At the same time, the two locking blocks are close to their corresponding locking blocks, so that the locking blocks are inserted into the locking grooves to achieve the positioning of the hydraulic cylinder. At the same time, the mobile component can be moved out of the relay room.

[0015] Optionally, the two driving blocks are spaced apart in a direction perpendicular to their sliding direction.

[0016] By adopting the above technical solution, the two drive blocks are arranged at intervals so that there will be no interference between the two drive blocks during the sliding process. In the actual construction process, the telescopic structure is in a retracted state (that is, the ends of the two rotating rods are in a state of being away from each other). In this state, the drive blocks are also located away from their corresponding locking blocks. Subsequently, the two drive blocks can be moved to drive the hydraulic cylinder to move. When the two rotating rods are parallel to each other, the hydraulic cylinder is in the extreme position away from the moving component. At this time, the hydraulic cylinder can enter the installation groove, and then the connection between the telescopic structure and the moving component is disconnected, and the drive blocks are continued to be moved. The two drive blocks are away from each other and continue to approach the locking block. At this time, the telescopic structure shrinks in the direction close to the hydraulic cylinder until the drive block abuts against the locking block and drives the locking block to be inserted into the locking groove. There is no need to change the moving direction of the drive block during the whole process, which improves the continuity of the installation and disassembly process of the hydraulic cylinder.

[0017] Optionally, a driving assembly for driving the driving blocks to move closer to or away from each other is provided on the mounting plate, and the driving assembly includes a driving rod and a driving member, the driving rod is rotatably connected between the two driving blocks, the driving rod is provided with two thread grooves with opposite rotation directions, and threads in opposite directions that fit in the thread grooves are respectively provided on the side surfaces of the driving blocks close to the driving rod corresponding to the two thread grooves.

[0018] By adopting the above technical solution, the two driving blocks are threadedly connected to the driving rod, thereby realizing synchronous driving of the driving blocks.

[0019] Optionally, the moving component includes a connecting rod, a connecting groove is provided on the connecting rod corresponding to the telescopic structure, a sliding groove is provided on the side wall of the connecting groove perpendicular to the rotation axis of the rotating rod, a rotating shaft is provided at the end of the rotating rod away from the driving block, one end of the rotating shaft is inserted in the sliding groove, and can slide along the length direction of the sliding groove.

[0020] By adopting the above technical solution, the rotating shaft is inserted into the sliding groove, so as to realize the sliding and rotating connection between the moving component and the rotating rod, thereby ensuring the telescopic function of the telescopic structure.

[0021] Optionally, a disengagement groove is provided on the connecting rod, and the disengagement groove is connected to the sliding groove. When the two rotating rods are parallel, the rotating axis corresponds to the disengagement groove.

[0022] By adopting the above technical solution, when installing the hydraulic cylinder, the driving block drives the two rotating rods to rotate, and then drives the two rotating shafts to slide and rotate in the sliding groove. When the two rotating rods are parallel, the hydraulic cylinder is inserted into the installation groove, and the rotating shaft corresponds to the disengagement groove. Thereafter, as the driving block continues to move, the rotating shaft can be disengaged from the disengagement groove, so that the telescopic structure and the moving component are automatically disconnected, thereby improving construction efficiency. Conversely, the same is true during the disassembly process. When the two rotating rods are parallel to each other, the rotating shaft is placed in the disengagement groove, and then enters the sliding groove to realize the connection between the telescopic structure and the moving component.

[0023] Optionally, a pre-connection component is provided on the side wall of the mounting groove, and the pre-connection component includes a block and an elastic member, the block is connected to the side wall of the mounting groove in a direction perpendicular to the sliding direction of the hydraulic cylinder, and the mounting plate is provided with a block groove for inserting one side of the block; the block is provided with a guide slope, the guide slope is used to guide the block away from the hydraulic cylinder, and the elastic member is used to apply a force to the block to make the block close to the hydraulic cylinder.

[0024] By adopting the above technical solution, after the hydraulic cylinder is installed in the installation groove, the hydraulic cylinder can be initially fixed in the installation groove under the action of the elastic member and the stopper, preventing the hydraulic cylinder from being separated from the installation groove during the contraction of the telescopic structure. During the disassembly of the hydraulic cylinder, the telescopic structure exerts a force on the hydraulic cylinder, and the hydraulic cylinder overcomes the elastic force of the elastic member and is separated from the installation groove, which facilitates the disassembly of the hydraulic cylinder.

[0025] Optionally, a monitoring system is provided on the inner cylinder, and the monitoring system includes a reference block, a distance measuring module and an industrial computer; the reference block and the distance measuring module are respectively provided on the inner cylinder and the outer cylinder, the distance measuring module is used to monitor the distance between the reference block and the distance measuring module itself, and the industrial computer is used to receive the distance information measured by the distance measuring module and calculate the displacement of the reference block in the vertical direction at different times;

[0026] The method for the industrial computer to calculate the displacement of the reference block in the vertical direction comprises:

[0027] The reference block is provided with a reference inclined surface inclined along the vertical direction;

[0028] S1: Benchmark measurement, when the relay room is not working, measure the distance L1 between the reference point on the reference slope and the ranging module;

[0029] S2: Normal measurement, during the hydraulic cylinder ejection process, the distance L2 between the reference point and the distance measurement module is measured again;

[0030] S12: Distance conversion,

[0031] The vertical offset (B) between the inner cylinder and the outer cylinder is calculated by using the distance L2 measured in step S21 and the distance L1 measured in step S20.

[0032] By adopting the above technical solution, the distance measuring module detects the distance of the reference point on the reference inclined plane. When the inner cylinder and the outer cylinder are relatively displaced in the vertical direction, the distance measured by the distance measuring module changes. Through the relationship between the reference inclined plane and the distance L, the displacement of the reference block relative to the distance measuring module in the vertical direction is obtained, thereby reflecting the change of the inner cylinder and the outer cylinder in the vertical direction. By monitoring this change, the staff can effectively control the working status of the relay room, reduce the deformation of the relay room, and effectively prevent the occurrence of disasters.

In this embodiment, the outer cylinder 11 and the inner cylinder 12 are both circular cylindrical structures, the outer cylinder 11 is sleeved outside the inner cylinder 12, and the outer cylinder 11 can slide relative to the outer cylinder 11 along its own length direction. The hydraulic cylinder 13 is arranged in a direction parallel to the axis of the inner cylinder 12, and a plurality of them are evenly spaced along the circumference of the inner cylinder 12 (the specific number is set according to the actual situation of the pipe jacking construction). Six are set in this embodiment. A quick locking assembly 2 is provided on the hydraulic cylinder 13, and the quick locking assembly 2 is used to fix the support frame 323, thereby realizing the rapid installation and disassembly of the hydraulic cylinder 13.

The two ends of the hydraulic cylinder 13 are respectively abutted on the two abutment rings 14. The expansion and contraction of the hydraulic cylinder 13 can drive the inner tube 12 and the outer tube 11 to move relative to each other, thereby realizing the pipe jacking action.

[0046] Reference Figure 1 and Figure 2A mounting ring 15 is coaxially arranged on the inner wall of the inner cylinder 12, and the outer wall of the mounting ring 15 is welded to the inner wall of the inner cylinder 12. The mounting ring 15 is arranged in parallel with the abutting ring 14, and the cylinder body of the hydraulic cylinder 13 is located between the mounting ring 15 and the abutting ring 14. Mounting grooves 16 are provided on the abutting ring 14 and the mounting ring 15 at both ends of the cylinder body of the hydraulic cylinder 13, and both ends of the cylinder body of the hydraulic cylinder 13 are inserted into the mounting grooves 16 to improve the stability of the hydraulic cylinder 13 after installation. The mounting groove 16 forms an opening on the inner wall of the mounting ring 15 and the abutting ring 14, and both ends of the cylinder body of the hydraulic cylinder 13 are slidably fitted in the mounting groove 16 along the radial direction of the inner ring. The hydraulic cylinder 13 can be disengaged from the mounting groove 16 by moving the hydraulic cylinder 13 along the radial direction of the mounting ring 15.

[0047] Reference Figure 2 and Figure 3 The quick locking assembly 2 includes a locking block 21, which is slidably connected to the hydraulic cylinder 13. A locking groove 24 is correspondingly provided on the inner tube 12. The sliding locking block 21 is inserted into the locking groove 24, thereby limiting the position of the hydraulic cylinder 13 and further realizing the rapid disassembly of the hydraulic cylinder 13.

[0048] Reference Figure 2 and Figure 3 The quick locking assembly 2 also includes a mounting frame 22, which includes a mounting plate 221 and a hoop 222. The mounting plate 221 is arranged on one side of the hydraulic cylinder 13 in a direction perpendicular to the length direction of the hydraulic cylinder 13. The hoop 222 is a U-shaped structure, the opening of the hoop 222 faces the mounting plate 221, and the hoop 222 is arranged outside the hydraulic cylinder 13. Both ends of the hoop 222 are welded to the mounting plate 221 to fix the hydraulic cylinder 13. The locking block 21 is installed on the side of the mounting plate 221 away from the hydraulic cylinder 13 to facilitate the connection between the locking block 21 and the hydraulic cylinder 13.

[0049] Reference Figure 2 and Figure 3 The quick locking assembly 2 also includes a driving block 23, which is slidably connected to the side of the mounting plate 221 away from the hydraulic cylinder 13 in a direction parallel to the length direction of the hydraulic cylinder 13. The locking block 21 is arranged on one side of the sliding direction trajectory of the locking block 21 in a direction perpendicular to the sliding direction of the driving block 23, and the sliding direction of the locking block 21 is perpendicular to the sliding direction of the driving block 23. A driving inclined surface is arranged on the driving block 23, and the sliding driving block 23 and the driving inclined surface abut against the locking block 21 can drive the locking block 21 to slide in a direction away from the driving block 23. A driving assembly 5 for driving the driving blocks 23 to move closer to or away from each other is arranged on the mounting frame 22, so as to facilitate automatic control of the movement of the driving block 23.

[0050] In order to further improve the stability of the hydraulic cylinder 13 after installation, the locking blocks 21 can be provided in multiple numbers. In this embodiment, two locking blocks 21 are provided. The two locking blocks 21 are respectively located near the two ends of the hydraulic cylinder 13. The two driving blocks are located between the two locking blocks.

[0051] Reference Figure 1 and Figure 4 , a pick-and-place device 3 is also provided on the mounting plate 221, and the pick-and-place device 3 includes a telescopic structure 31 and a moving assembly 32. The telescopic structure 31 is provided in multiples corresponding to the multiple hydraulic cylinders 13. One end of the telescopic structure 31 is connected to the mounting plate 221, and the other end is connected to the moving assembly 32. The moving assembly 32 is used to drive the telescopic structure 31 to move along the axis of the inner tube 12. Rollers are provided at the bottom of the moving assembly 32 to facilitate the sliding of the moving assembly 32 on the track laid inside the pipeline. By controlling the operation of the telescopic structure 31, the hydraulic cylinder 13 can be driven to move radially along the inner tube 12, thereby causing the hydraulic cylinder 13 to detach from the mounting groove 16, or enter the mounting groove 16, to realize the automatic disassembly and installation of the hydraulic cylinder 13, further reducing the labor burden of the staff and improving the construction efficiency.

[0052] Reference Figure 2 and Figure 3 The telescopic structure 31 includes two rotating rods 311, which are rotatably connected to each other, and the axis of the rotating rod 311 is located in the middle of its length direction. The two rotating rods 311 are arranged corresponding to the two driving blocks 23, one end of the rotating rod 311 is rotatably connected to the driving block 23, and the other end is connected to the moving assembly 32. The rotating rod 311 can drive the hydraulic cylinder 13 to move radially along the inner tube 12.

[0053] Reference Figure 1 and Figure 2 The moving assembly 32 includes a connecting rod 321, a bottom plate 322 and a support frame 323. The support frame 323 is welded to the bottom plate 322, and the roller is rotatably connected to the bottom plate 322, so as to realize the movement of the moving assembly 32. The connecting rod 321 is a cylindrical structure, and the connecting rod 321 is coaxially arranged with the inner cylinder 12. The connecting rod 321 is welded to the support frame 323, and the end of the rotating rod 311 away from the driving block 23 is rotatably connected to the connecting rod 321, and can slide along the length direction of the connecting rod 321.

[0054] Reference Figure 2 and Figure 5The two driving blocks 23 are spaced apart in a direction perpendicular to their own sliding direction, so that the two driving blocks 23 will not interfere with each other during the sliding process. At the same time, without changing the sliding direction of the driving blocks 23, the two driving blocks 23 can first approach each other and then move away from each other, so that the moving direction of the driving blocks 23 does not need to be changed during the installation or removal of the hydraulic cylinder 13, making the installation and removal process of the hydraulic cylinder 13 more continuous, further improving the efficiency of the installation or removal of the hydraulic cylinder 13.

[0055] Reference Figure 2 and Figure 5 The driving assembly 5 includes a driving rod 51 rotatably connected to the mounting plate 221 and a driving member 52 for driving the driving rod 51 to rotate. The driving rod 51 is arranged in a direction parallel to the sliding direction of the driving block 23 and is located between the sliding paths of the two driving blocks 23. In this embodiment, the driving member 52 is a servo motor, and the output shaft of the servo motor is connected to the driving rod 51 to drive the driving rod 51 to rotate. The driving rod 51 is provided with two thread grooves with opposite rotation directions, and the trajectory lines of the two thread grooves in the length direction coincide. The side wall of the driving block 23 close to the driving rod 51 is provided with threads with opposite rotation directions. The threads on the two driving blocks 23 respectively cooperate with the two thread grooves with opposite rotation directions to achieve the synchronous approach or distance between the driving blocks 23.

[0056] Reference Figure 1 and Figure 2 , the end of the rotating rod 311 connected to the driving block 23 is defined as the driving end, and the end of the rotating rod 311 away from the driving block 23 is defined as the driven end. Figure 6 , a rotating shaft 326 is welded on the driven end, and two connecting grooves 324 are provided on the connecting rod 321 corresponding to the two rotating shafts 326, and the driven end is inserted into the connecting grooves 324. A sliding groove 325 is provided on the side wall of the connecting groove 324 perpendicular to the rotating shaft 326, and one end of the rotating shaft 326 away from the rotating rod 311 is inserted into the sliding groove 325. The rotating shaft 326 can rotate and slide in the sliding groove 325, so as to realize the rotation and sliding between the driven end and the connecting rod 321.

[0057] Reference Figure 2 and Figure 6 A disengagement groove 327 is provided on the connecting rod 321 at a position corresponding to the sliding groove 325. When the length directions of the two rotating rods 311 are parallel to each other, the rotating shaft 326 corresponds to the disengagement groove 327. At this time, the rotating shaft 326 can be disengaged from the disengagement groove 327, so that after the hydraulic cylinder 13 is installed in place, continuing to move the driving block 23 can drive the rotating rod 311 to disengage from the sliding groove 325, thereby automatically realizing the disconnection between the telescopic structure 31 and the moving component 32.

[0058] Reference Figure 2 and Figure 6, the driven ends of the two rotating rods 311 are defined as the first end and the second end respectively. Before the hydraulic cylinder 13 is installed, the rotating shaft 326 is located in the sliding groove 325 and is located at the end away from the disengagement groove 327. At this time, the telescopic structure 31 is in a retracted state, and the hydraulic cylinder 13 is located near the moving component 32. This state is defined as the initial state of the telescopic structure 31.

[0059] Reference Figure 1 and Figure 2 During the construction process, the telescopic structure 31 is in the initial state. At this time, the inner tube 12 and the outer tube 11 of the relay room are pushed into the tunnel by the jacking equipment, and then the hydraulic cylinder 13 is driven to move to the inside of the inner tube 12 by the moving assembly 32, and multiple hydraulic cylinders 13 are evenly arranged around the axis of the inner tube 12. The moving direction of the driving block 23 when the two driven ends move in the direction close to the disengagement groove 327 is defined as the installation direction, and the driving block 23 is moved along the installation direction to make the two driving blocks 23 approach each other, driving the two driven ends of the rotating rod 311 to also approach each other and approach the disengagement groove 327.

[0060] Reference Figure 1 and Figure 2 As the driving block 23 moves, when the positions of the two driving blocks 23 correspond to each other (that is, when the two rotating rods 311 are parallel to each other), the hydraulic cylinder 13 enters the installation groove 16. Figure 6 At the same time, the rotating shaft 326 corresponds to the disengagement slot 327. At this time, the driving block 23 continues to be moved along the first direction, and the rotating shaft 326 disengages from the sliding slot 325, automatically disconnecting the connection between the moving assembly 32 and the connecting rod 321. The driving block 23 continues to be moved along the installation direction, and the two driving blocks 23 move away from each other. When the driving block 23 abuts against the locking block 21, the locking block 21 is driven to move, thereby limiting the hydraulic cylinder 13. At the same time, the connecting rod 321 is driven to approach the hydraulic cylinder 13, reducing the space occupied by the telescopic structure 31 and reducing the impact on the laying of the track in the inner cylinder 12.

[0061] Reference Figure 1 and Figure 2In order to reduce the possibility that the hydraulic cylinder 13 is disengaged from the mounting groove 16 before the locking block 21 is inserted into the locking groove 24, a pre-connection assembly 4 is provided on the side wall of the mounting groove 16. The pre-connection assembly 4 includes a stopper 41 and a reset member 42. A receiving groove 43 is provided on the side wall of the mounting groove 16. A stopper groove is provided on the mounting plate 221 corresponding to the stopper 41. One end of the stopper 41 can be inserted into the stopper groove, thereby preventing the hydraulic cylinder 13 from disengaging from the mounting groove 16. The elastic member 25 is also provided in the receiving groove 43, and is used to keep the stopper 41 from moving out of the receiving groove 43. In this embodiment, the reset member 42 is a spring, one end of which is welded to the side wall of the receiving groove 43, and the other end is welded to the stopper 41. Under the action of the reset member 42, the stopper 41 can prevent the hydraulic cylinder 13 from disengaging from the mounting groove 16. The stopper 41 is provided with guiding inclined surfaces 44 on both sides perpendicular to the sliding direction of the hydraulic cylinder 13, and the guiding inclined surfaces 44 are inclined in a direction of approaching each other from a side close to the receiving groove 43 to a side away from the receiving groove 43 along the sliding direction of the stopper 41. When a sufficiently large force is applied to the hydraulic cylinder 13, the stopper 41 can overcome the elastic force of the reset member 42 and enter the receiving groove 43 under the action of the guiding inclined surfaces 44, thereby facilitating the removal and installation of the hydraulic cylinder 13.

[0062] Reference Figure 1 and Figure 2 When the hydraulic cylinder 13 needs to be disassembled, the moving assembly 32 is moved to a specific position inside the inner tube 12 in advance. Then the two driving blocks 23 are controlled to move in the disassembly direction (the opposite direction of the installation direction). After the driving block 23 is disengaged from the locking block 21, the locking block 21 automatically disengages from the locking groove 24 under the action of the elastic member 25. At this time, the pre-connection assembly 4 supports the hydraulic cylinder 13 and prevents the hydraulic cylinder 13 from disengaging from the installation groove 16. Figure 6 As the driving block 23 moves, when the length directions of the two rotating rods 311 are parallel, the rotating shaft 326 enters the disengagement groove 327 and corresponds to the sliding groove 325. Then, the driving block 23 continues to move, and the rotating shaft 326 enters the sliding groove 325, so that the rotating rod 311 is connected with the connecting rod 321. At this time, under the action of the rotating rod 311, a force is applied to the hydraulic cylinder 13 to move it to the outside of the installation groove 16. Under the action of the force, the stopper 41 overcomes the elastic force of the reset member 42 and sinks into the receiving groove 43. Then, the hydraulic cylinder 13 can be disengaged from the installation groove 16, and the automatic disassembly of the hydraulic cylinder 13 is realized.

[0063] Reference Figure 1 and Figure 2During the process of jacking the pipe in the relay room, as the ejection length increases, the shear force on both ends becomes greater. Under the action of the shear force, the inner tube 12 and the outer tube 11 may be misaligned in the vertical direction, or the axes of the two may form an angle. In order to ensure the construction quality and safety, it is necessary to monitor the deformation of the relay room to effectively predict possible situations, reduce safety risks and ensure construction quality.

[0064] Reference Figure 1 and Figure 2 A monitoring system is set up inside the relay room. The detection system includes a reference block 6, a distance measuring module 62, and an industrial computer for receiving information measured by the distance measuring module 62 and processing the information; it also includes a display module connected to the industrial computer for displaying information and a power supply module for powering each module.

[0065] Reference Figure 1 and Figure 2 , the reference block 6 and the distance measuring module 62 are respectively mounted on the inner cylinder 12 and the outer cylinder 11. The distance measuring module 62 is used to measure the vertical distance between the reference point (the area point formed by the position corresponding to the distance measuring module 62 on the reference block 6) and itself. A reference inclined surface 61 is provided on the side of the reference block 6 close to the distance measuring module 62, and the reference inclined surface 61 is inclined in the vertical direction toward or away from the distance measuring module 62. In this embodiment, the reference inclined surface 61 is inclined in the vertically upward direction toward the distance measuring module 62.

[0066] When the inner cylinder 12 and the outer cylinder 11 are relatively deformed or displaced in the vertical direction, the position of the measuring point on the reference inclined plane 61 measured by the distance measuring module 62 changes, thereby causing the measurement information of the distance measuring module 62 to change accordingly.

[0067] Reference Figure 7 and Figure 8 , the detection system detection steps include:

[0068] S1: Calculate the deformation of the inner tube 12 and the outer tube 11 in the vertical direction

[0069] It includes the steps of:

[0070] S10: Benchmark measurement,

[0071] When the hydraulic cylinder 13 is not ejected, the distance L1 between the reference point and the distance measuring module 62 is measured for the first time in this state.

[0072] The specific measurement steps of S10 include:

[0073] S101: distance information collection.

[0074] The distance measurement module 62 includes a laser emission module, a laser receiving module, a timing module and a data processing module.

[0075] S102: The laser emission module serves as a light source to emit laser pulses to the target to be measured, and the timing module starts timing at the same time.

[0076] S103: The laser is reflected after being irradiated on the reference surface, and the laser receiving module receives the laser signal, while the timing module stops timing.

[0077] S04: The data processing module calculates the distance L between the reference point and the distance measurement module 62.

[0078] Specific: L = 1 / 2ct;

[0079] Wherein L is the distance between the reference point and the distance measurement module 62; c is the speed of light in the atmosphere; and t is the time interval between the laser emission and reception timing components.

[0080] S11: Normal measurement,

[0081] During the ejection process of the hydraulic cylinder 13, the distance L2 between the reference point and the distance measuring module 62 is measured again.

[0082] S12: Distance conversion,

[0083] The vertical offset (B) between the inner cylinder 12 and the outer cylinder 11 is calculated by the distance L2 measured in step S21 and the distance L1 measured in step S20, as follows:

[0084] B=(L2-L1) / tan(α)

[0085] In this embodiment, the reference inclined plane 61 is inclined in a vertically upward direction away from the distance measuring module 62 , and α is an angle (acute angle) between the reference inclined plane 61 and the vertical direction.

[0086] S13: Repeat steps S21 and S22 to obtain the offset B between the inner cylinder 12 and the outer cylinder 11 at times t1, t2, t3, ..., tn.

[0087] S2: Data output:

[0088] The offsets at multiple times are output through the display module, and the staff can analyze the working status of the relay room according to the change trends between the multiple offsets and monitor the working status of the relay room.

[0089] The implementation principle of a relay room for pipe jacking construction that is easy to disassemble and assemble in the embodiment of the present application is as follows: when disassembling the hydraulic cylinder, the connecting shaft is moved to a position coaxial with the inner cylinder inside the inner cylinder by the roller at the bottom of the moving assembly. The driving assembly drives the two driving blocks to slide along the installation direction, and the sliding of the driving blocks drives the rotating rod to rotate. As the rotating rod rotates, the hydraulic cylinder moves in the direction close to the installation groove. When the two rotating rods are parallel to each other, the hydraulic cylinder enters the installation groove. At the same time, the rotating shaft corresponds to the disengagement groove, and the driving block continues to be moved to drive the rotating rod to rotate, so that the rotating shaft is disengaged from the disengagement groove, so that the telescopic structure is disengaged from the moving assembly. At this time, the moving assembly can be moved out to facilitate the construction of other processes. When disassembling the hydraulic cylinder, the two driving blocks move along the disassembly direction. When the two rotating rods are parallel to each other, the rotating shaft corresponds to the sliding groove. At this time, the rotating shaft can enter the sliding groove to connect the telescopic structure with the moving assembly. Then, as the rotating assembly shrinks, the hydraulic cylinder is driven to disengage from the installation groove, realizing the rapid disassembly of the hydraulic cylinder.

[0090] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
