Description

Technical Field

[0001] This utility model relates to the field of pipe-laying construction technology, specifically to a pipe-laying construction device for a large-diameter steel pipe guide rail in a top-shield dual-mode tunneling system. Background Technology

[0002] The steel pipe guide rail pipe-threading construction equipment is a guiding and support system used for underground pipeline laying. It guides the steel pipe to be precisely threaded along the designed path through the guide rail, while providing stable support to ensure construction safety and efficiency. The top-shield dual-mode tunneling large-diameter steel pipe guide rail pipe-threading construction equipment is a composite tunneling equipment that integrates two technical modes: pipe jacking and shield tunneling. It is specifically designed for pipe-threading construction of large-diameter steel pipes under the constraint of guide rails. For example, in the prior art 1 (Chinese patent application number CN201721378697.1, application date 2017-10-24), a pipe jacking steel pipe threading device is used to directly jack the main pipeline. The main pipeline is equipped with a pipe sleeve to protect the anti-corrosion layer, which greatly improves the construction progress and reduces the damage to the external anti-corrosion layer of the threaded steel pipe.

[0003] While existing technologies can improve the efficiency of pipe threading in the later stages, the steel pipes may loosen and shift due to prolonged compression during the actual threading process, thus reducing the efficiency of pipe threading. At the same time, loosened and shifted steel pipes may be damaged due to excessive compression force, further reducing the efficiency of pipe threading and making them impractical. Therefore, the top-shield double-mode tunneling large-diameter steel pipe guide rail threading construction equipment has been proposed, which can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a top-shield double-mode tunneling large-diameter steel pipe guide rail pipe-threading construction equipment to solve the problem mentioned in the background art that the steel pipes on the market become loose and shift due to long-term compression, and that the loose and shifted steel pipes are damaged by excessive compression force, thus reducing the efficiency of pipe threading.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a top-shield dual-mode tunneling large-diameter steel pipe guide rail pipe-passing construction device, comprising an auxiliary plate and a control cabinet installed below the auxiliary plate, wherein a guide rail is slidably connected to the bottom of the control cabinet via an auxiliary groove, a stepper motor is provided on the outer side of the control cabinet, and the output end of the stepper motor is connected to the output end of a moving wheel via gear transmission, a moving wheel is also provided below the control cabinet, and a guide rail is slidably connected to the bottom of the two moving wheels, two positioning clamps with identical structures are slidably installed on the top of the auxiliary plate, and anti-slip pads are attached to the inner sides of the two positioning clamps, and a positioning component is provided inside the positioning clamp, wherein the positioning component includes two limiting blocks, the two limiting blocks are slidably installed inside the positioning clamp, and two rows of limiting grooves are opened inside the auxiliary plate, wherein the limiting grooves and the limiting blocks form a snap-fit ​​connection.

[0006] Preferably, one end of two compression springs is fixedly connected inside the positioning clamp, and the other end of the two compression springs is fixedly connected to a limit block, and the two compression springs have the same structure.

[0007] Preferably, the outer surfaces of the two limiting blocks are inclined, and the two limiting blocks are symmetrically arranged about the vertical center line of the positioning clamp.

[0008] Preferably, two levers are slidably mounted on the outer side of the positioning clamp, and one end of a pull rope is fixedly connected to the side of the two levers near the positioning clamp, and the other end of the two pull ropes is fixedly connected to a limit block through a guide wheel.

[0009] Preferably, a return spring is provided on the outer side of the positioning clamp, and a lever is connected to each end of the return spring.

[0010] Preferably, a top plate is slidably installed inside the auxiliary plate, and a positioning clamp is correspondingly provided on the outer side of the top plate. One end of two extrusion rods is rotatably connected to the inner side of the top plate, and a moving block is rotatably connected to the other end of the two extrusion rods. The two extrusion rods are in an inclined shape.

[0011] Preferably, the auxiliary plate has two energy storage springs fixedly connected to one end, and the other end of the two energy storage springs is fixedly connected to a moving block, and the two moving blocks are symmetrically slidably installed inside the auxiliary plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) Before the pipe-threading construction equipment for the top shield double-mode tunneling large-diameter steel pipe guide rail, the steel pipe is placed on the auxiliary plate, and then two positioning clamps are squeezed at the same time to clamp and position the placed steel pipe through two anti-slip pads, so as to avoid the phenomenon of squeezing and damage to the steel pipe in the later stage due to misalignment and displacement, and improve the efficiency of pipe-threading in the later stage.

[0014] (2) In the process of the positioning clamps being squeezed and contracted, the two inclined limiting blocks will contract and move by the squeezing of the auxiliary plate. Then, the two compression springs will use their own elasticity to push the two limiting blocks into the two rows of limiting grooves in sequence, so as to fix the position of the positioning clamps after sliding, and avoid the phenomenon of the two positioning clamps loosening and falling off during the clamping and positioning of the steel pipe in the later stage, thus improving stability.

[0015] (3) When the steel pipe is to be released from clamping after being inserted, the double-mode tunneling equipment for large-diameter steel pipe guide rail can simply press two levers to move two pull ropes. At this time, the two pull ropes will pull two limit blocks to move through the guide wheel, so that the two limit blocks are separated from the two limit grooves. Then the positioning clamp can be reset and moved, so that the steel pipe can be released from clamping. The operation is more time-saving and labor-saving.

[0016] (4) The top shield double-mode tunneling large-diameter steel pipe guide rail pipe-passing construction equipment utilizes a reset spring set on the outside of the positioning clamp, and then connects levers to both ends of the reset spring. The reset spring can use its own elastic force to elastically reset the two levers after pressing and retracting, so as to facilitate repeated disassembly and assembly operations in the later stage.

[0017] (5) In the process of the positioning clamp plate squeezing and moving, the positioning clamp plate will simultaneously squeeze the top plate to retract and move. At this time, the retracting and moving top plate will simultaneously drive the two squeezing rods to drive the two moving blocks to squeeze and store the two energy storage springs, so as to facilitate the later disassembly of the positioning clamp plate. During the disassembly and replacement of the positioning clamp plate, the two squeezing and storing energy springs will reset the two squeezing and retracting moving blocks through their own elasticity. Then, the two moving blocks will drive the squeezing rods to reset the positioning clamp plate through the two squeezing rods, thereby assisting the later disassembly and reset of the positioning clamp plate and reducing the disassembly and assembly burden of the workers.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides the following technical solution: a pipe-threading construction device for large-diameter steel pipe guide rails in top-shield dual-mode tunneling:

[0028] Example 1: To address the issue of existing steel pipes becoming loose and shifting due to prolonged compression, and the resulting damage from excessive compression force, thus reducing pipe threading efficiency, the following solution is disclosed: an auxiliary plate 1 and a control cabinet 2 installed below the auxiliary plate 1. A guide rail 4 is slidably connected to the bottom of the control cabinet 2 via an auxiliary groove 5. A stepper motor 8 is mounted on the outer side of the control cabinet 2, and its output is connected to the output of a moving wheel 3 via gear transmission. Moving wheels 3 are also located below the control cabinet 2, and the guide rail 4 is slidably connected to the bottom of both moving wheels 3. Before pipe threading, the steel pipe is placed on the auxiliary plate 1, and two positioning clamps 6 are simultaneously pressed, with two anti-slip pads 7 clamping and positioning the placed steel pipe to prevent damage from misalignment later, thus improving pipe threading efficiency. Then, the stepper motor 8 is activated to drive the two moving wheels 3 to slide within the guide rail 4, assisting in the subsequent pipe threading process. Figures 1-3 As shown.

[0029] Two identical positioning clamps 6 are slidably mounted on the top of the auxiliary plate 1, and anti-slip pads 7 are attached to the inner sides of the two positioning clamps 6. Positioning components are provided inside the positioning clamps 6, including two limiting blocks 17, which are slidably mounted inside the positioning clamps 6. Two rows of limiting grooves 9 are formed inside the auxiliary plate 1, and the limiting grooves 9 and the limiting blocks 17 are engaged. Two compression springs 18 are fixedly connected to one end inside the positioning clamps 6, and the other end of the two compression springs 18 is fixedly connected to the limiting blocks 17. The structures of the two compression springs 18 are identical. Similarly, the outer surfaces of the two limiting blocks 17 are inclined, and the two limiting blocks 17 are symmetrically arranged about the vertical center line of the positioning clamp 6. During the compression and contraction movement of the positioning clamp 6, the two inclined limiting blocks 17 will contract and move due to the compression of the auxiliary plate 1. Subsequently, the two compression springs 18 will use their own elasticity to spring the two limiting blocks 17 into the interior of the two rows of limiting grooves 9 in sequence, so as to fix the position of the sliding positioning clamp 6, and avoid the two positioning clamps 6 from loosening and falling off during the clamping and positioning of the steel pipe later, thus improving stability. Figure 1 and Figure 7 As shown.

[0030] Two levers 10 are slidably mounted on the outer side of the positioning clamp 6. One end of a pull rope 11 is fixedly connected to the side of each lever 10 closest to the positioning clamp 6. The other ends of the two pull ropes 11 are fixedly connected to limit blocks 17 via guide wheels. A return spring 12 is provided on the outer side of the positioning clamp 6, with levers 10 connected to both ends of the return spring 12. When it is necessary to release the clamp on the steel pipe after it has been inserted, simply press the two levers 10, which will cause the two pull ropes 11 to retract and move via the return spring 12. This retracting pull rope will then simultaneously pull the two limit blocks 17 via the guide wheels, causing the two limit blocks 17 to retract and move, separating them from the two limit grooves 9. The positioning clamp 6 can then be reset, thus releasing the steel pipe from the clamp. This operation is more time-saving and labor-saving. Figures 3-7 As shown.

[0031] Example 2 differs from Example 1 in that a top plate 16 can be installed to assist in the quick disassembly of the top plate 16, thereby improving the efficiency of subsequent steel pipe assembly and disassembly and reducing the workload of workers. The following is disclosed:

[0032] A top plate 16 is slidably mounted inside the auxiliary plate 1, and a positioning clamp 6 is correspondingly mounted on the outer side of the top plate 16. Two pressing rods 13 are rotatably connected to one end of their inner side, and a moving block 14 is rotatably connected to the other end of each pressing rod 13. The two pressing rods 13 are inclined. Two storage springs 15 are fixedly connected to one end inside the auxiliary plate 1, and the moving block 14 is fixedly connected to the other end of each storage spring 15. The two moving blocks 14 are symmetrically slidably mounted inside the auxiliary plate 1. During the pressing and moving process of the positioning clamp 6, the positioning clamp 6 simultaneously presses the top plate 16 to retract. When the top plate 16 retracts and moves, it simultaneously drives the two pressing rods 13 to drive the two moving blocks 14 to press and store force on the two storage springs 15. This facilitates the subsequent disassembly of the positioning clamp 6. During the disassembly and replacement of the positioning clamp 6, the two pressing and storing force springs 15 can use their own elasticity to reset the two pressing and retracting moving blocks 14. Subsequently, the two moving blocks 14 will drive the pressing rods 13 to reset the positioning clamp 6 through the two pressing rods 13, thereby assisting in the subsequent disassembly and reset of the positioning clamp 6, reducing the disassembly and assembly burden on the workers. Figure 5 and Figure 6 As shown.
