[0002] With the large-scale development of urban construction, it is necessary to lay sewage interception pipes or energy (liquefied gas, natural gas, etc.) supply pipes in the city. The more common method is to dig trenches to bury pipes and cables, which will cause environmental pollution, traffic jams, and construction safety hazards. Therefore, trenchless pipe laying technology has been developed and used. That is, a construction technology that uses rock and soil drilling methods to lay, repair and replace underground pipelines without digging trenches on the road surface and destroying a large area of ​​the surface layer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the present invention performs active interference detection and needs to move along the drilling path while observing each frequency band, the fixed frame is directly pushed, and the fixed frame and the movable frame move through the wheels at the bottom, and the movable frame drives the guide instrument to move, which saves the operator from operating the guide instrument by hand. In addition, during the movement, the receiving plate can be removed from the connecting frame and placed at the destination so that the laser is irradiated onto the receiving plate.

[0016] During the movement of the material storage box along the guide rod, the present invention utilizes the intermittent protrusion design of the guide rod. During the movement of the inner cylinder on the material storage box on the guide rod, the inner cylinder and the connecting buckle can be intermittently opened and closed, thereby allowing the material inside the material storage box to intermittently enter the inside of the connecting buckle, and then be intermittently dropped onto the ground through the connecting buckle as a mark. On the one hand, leaving the mark on the ground can facilitate the operator to record the moving route of the guide instrument. On the other hand, the design of intermittent material dropping can not only record the route, but also save the use of materials, save resources and reduce costs.

[0017] In the process of main shaft rotation of the present invention, a part of the surface of the main shaft extending to the inside of the piston cylinder is provided with a thread, and a push piece is arranged on the threaded part, and the push piece and the thread are connected by a ball nut pair. Therefore, when the main shaft rotates, the push piece moves along the main shaft, and when the stabilizing rod moves downward, the internal pressure of the piston cylinder will be changed. The pressure change will force the stabilizing rod to move downward, causing the stabilizing rod to penetrate into the ground, thereby ensuring the stability of the fixed frame and avoiding interference with the calibration confirmation process due to the instability of the fixed frame during the movement of the guide instrument.

[0031] See also Figure 2 as well as Figure 3 As shown, the clamping connection between the movable frame 22 and the fixed frame 1 can be eliminated, thereby making the fixed frame 1 immobile, and allowing the guide instrument 5 to follow the movable frame 22 and detach from the fixed frame 1 to move freely. When the movable frame 22 moves, the first telescopic rod 34 is pulled, and the length design of the first telescopic rod 34 can adjust the moving distance of the guide instrument 5.

[0032] The material storage box 21 is installed on the rotating seat 31, and the rotating seat 31 is provided with a motor 23. The output end of the motor 23 is provided with a synchronous belt 27 connected to the slide seat 33, and a guide rod 28 is provided on one side of the slide seat 33. One side of the material storage box 21 is connected to the synchronous belt 27 and when the synchronous belt 27 is working, the material storage box 21 is driven by the synchronous belt 27 and moves on the guide rod 28; the material storage box 21 is connected with a connecting buckle 29. When the material storage box 21 moves along the guide rod 28, the connecting buckle 29 uses the intermittent protrusion design of the guide rod 28 to make the material storage box 21 The material is dropped onto the ground; a connecting buckle 29 connected to the synchronous belt 27 is provided on one side of the storage box 21, a second telescopic rod 35 is provided on one side of the mobile frame 22, one end of the second telescopic rod 35 is connected to the fixed box 41, an inner cylinder is provided inside the storage box 21, the inner cylinder is connected to the connecting buckle 29, and the inner cylinder is connected to the guide rod 28, a connecting frame 26 is fixed on the mobile frame 22, the connecting frame 26 is located on one side of the slide 33, one end of the first telescopic rod 34 is fixedly connected to the connecting frame 26, and the receiving plate 25 is fixed to the connecting frame 26;

[0033] See also Figures 3 to 7 As shown, when the fixing frame 1 is pushed to move the guide instrument 5, the motor 23 is started, and the output end of the motor 23 drives the synchronous belt 27 to work. When the synchronous belt 27 works, it drives the storage box 21 to move through the connecting buckle 29. When the storage box 21 moves along the guide rod 28, refer to Figure 6 As shown, by utilizing the intermittent protrusion design of the guide rod 28, during the movement of the inner cylinder on the storage box 21 on the guide rod 28, the inner cylinder and the connecting buckle 29 can be intermittently opened and closed, thereby allowing the material inside the storage box 21 to intermittently enter the connecting buckle 29, and then be intermittently dropped onto the ground through the connecting buckle 29 as a mark. On the one hand, leaving marks on the ground can facilitate the operator to record the moving route of the guide instrument 5. On the other hand, the design of intermittent material delivery can not only record the route, but also save the use of materials, save resources and reduce costs.

[0034] See also Figure 3 as well as Figure 4 When the guide instrument 5 is free to move by separating the movable frame 22 from the fixed frame 1, the rotating seat 31 can be rotated, the rotating seat 31 drives the first telescopic rod 34 to rotate, the first telescopic rod 34 drives the connecting frame 26 to rotate, and the connecting frame 26 drives the movable frame 22 to rotate, thereby changing the deflection angle of the guide instrument 5, thereby freely adjusting the moving direction of the guide instrument 5, which is convenient for the operator to debug on site; in addition, this process does not require starting the motor 23.

[0035] A pre-tightening mechanism 4 is provided below the fixed frame 1 to ensure the stability of the fixed frame 1 when the mobile frame 22 moves. The pre-tightening mechanism 4 includes a fixed box 41 connected to the rotating seat 31. A main shaft 47 with a torsion spring structure runs through the fixed box 41. A traction rope 43 with one end connected to the mobile frame 22 is wound around the main shaft 47. A piston cylinder 44 is provided below the fixed box 41. A stabilizing rod 45 slides inside the piston cylinder 44. One end of the main shaft 47 extends to the inside of the piston cylinder 44. When the traction rope 43 is pulled and the main shaft 47 is driven to rotate, the main shaft 47 extends to one end of the piston cylinder 44. The internal pressure of the piston cylinder 44 is compressed to force the stabilizing rod 45 to move downward. A connecting plate 42 is fixed to one side of the fixed box 41. The connecting plate 42 is fixedly connected to the rotating seat 31. The traction rope 43 is connected to the fixed box 41 through and there is a scale on the traction rope 43. A part of the surface of the main shaft 47 extending to the inside of the piston cylinder 44 is threaded. A push piece 46 is provided on the threaded part. The push piece 46 is connected to the thread through a ball nut pair. When the main shaft 47 rotates, the push piece 46 moves along the main shaft 47. When the push piece 46 moves inside the piston cylinder 44, it drives the stabilizing rod 45 to move downward.

[0036] See also Figure 4 , Figure 5 as well as Figure 8As shown, during the confirmation calibration process, the receiver, sensor and related components are placed on the fixed frame 1, and the mobile frame 22 is pulled to separate the guide instrument 5 from the fixed frame 1. When the auxiliary mechanism 2 drives the guide instrument 5 to move away from the fixed frame 1, the mobile frame 22 pulls the traction rope 43. Since the other end of the traction rope 43 is wound around the main shaft 47, when the mobile frame 22 pulls the traction rope 43, the traction rope 43 drives the main shaft 47 to rotate. By pulling the length of the traction rope 43, the distance between the guide instrument 5 and the fixed frame 1 is adjusted to ensure whether the depth value is in compliance with the inspection, thereby ensuring accurate calibration; In addition, during the rotation of the main shaft 47, since a portion of the surface of the main shaft 47 extending to the inside of the piston cylinder 44 is threaded, and a push piece 46 is provided on the threaded portion, and the push piece 46 is connected to the thread by a ball nut pair, when the main shaft 47 rotates, the push piece 46 moves along the main shaft 47, and when the stabilizing rod 45 moves downward, the internal pressure of the piston cylinder 44 will change. The pressure change will force the stabilizing rod 45 to move downward, causing the stabilizing rod 45 to penetrate into the ground, thereby ensuring the stability of the fixed frame 1 and avoiding interference with the calibration confirmation process due to the instability of the fixed frame 1 during the movement of the guide instrument 5.

[0037] Working principle: When performing active interference detection, it is necessary to observe each frequency band while moving along the drilling path, and directly push the fixed frame 1. The fixed frame 1 and the mobile frame 22 move through the wheels at the bottom, and the mobile frame 22 drives the guide instrument 5 to move. In addition, during the movement, the receiving plate 25 can be removed from the connecting frame 26 and placed at the destination so that the laser 24 can be irradiated onto the receiving plate 25. During the movement of the guide instrument 5, the movement of the guide instrument 5 can be observed by the situation of the laser 24 irradiating the receiving plate 25;

[0038] When the fixing frame 1 is pushed to move the guide instrument 5, the motor 23 is started, and the output end of the motor 23 drives the synchronous belt 27 to work. When the synchronous belt 27 works, it drives the storage box 21 to move through the connecting buckle 29. When the storage box 21 moves along the guide rod 28, Figure 6 As shown, by utilizing the intermittent protrusion design of the guide rod 28, during the movement of the inner cylinder on the storage box 21 on the guide rod 28, the inner cylinder and the connecting buckle 29 can be intermittently opened and closed, thereby allowing the material inside the storage box 21 to intermittently enter the connecting buckle 29, and then be intermittently dropped onto the ground through the connecting buckle 29 as a mark.

[0039] In addition, the clamping connection between the mobile frame 22 and the fixed frame 1 can be cancelled, so that the fixed frame 1 can be immobilized, and the guide instrument 5 can follow the mobile frame 22 to separate from the fixed frame 1 and move freely; when the guide instrument 5 is free to move by separating the mobile frame 22 from the fixed frame 1, the rotating seat 31 can be rotated, the rotating seat 31 drives the first telescopic rod 34 to rotate, the first telescopic rod 34 drives the connecting frame 26 to rotate, and the connecting frame 26 drives the mobile frame 22 to rotate, thereby changing the deflection angle of the guide instrument 5, thereby freely adjusting the moving direction of the guide instrument 5, which is convenient for the operator to debug on site; in addition, this process does not require starting the motor 23;

[0040] During the confirmation calibration process, the receiver, sensor and related components are placed on the fixed frame 1, and the mobile frame 22 is pulled to separate the guide instrument 5 from the fixed frame 1. When the auxiliary mechanism 2 drives the guide instrument 5 to move away from the fixed frame 1, the mobile frame 22 pulls the traction rope 43. Since the other end of the traction rope 43 is wrapped around the main shaft 47, when the mobile frame 22 pulls the traction rope 43, the traction rope 43 drives the main shaft 47 to rotate. By pulling the length of the traction rope 43, the distance between the guide instrument 5 and the fixed frame 1 is adjusted to ensure that the depth value is checked to ensure accuracy of the calibration.

[0041] In addition, during the rotation of the main shaft 47, since a portion of the surface of the main shaft 47 extending to the inside of the piston cylinder 44 is threaded, and a push piece 46 is provided on the threaded portion, and the push piece 46 is connected to the thread through a ball nut pair, when the main shaft 47 rotates, the push piece 46 moves along the main shaft 47, and when the stabilizing rod 45 moves downward, the internal pressure of the piston cylinder 44 will change. The pressure change will force the stabilizing rod 45 to move downward, causing the stabilizing rod 45 to penetrate into the ground, thereby ensuring the stability of the fixing frame 1.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
