Description

Technical Field

[0001] The present invention belongs to the technical field of pipe jacking construction equipment, and particularly relates to an adjustable support guide rail for pipe jacking construction. Background Technique

[0002] Pipe jacking technology is a non-excavation pipe laying construction technology used for municipal construction. Generally, a working shaft is made perpendicular to the ground, and then a high-pressure hydraulic jack is used to push a cement or steel pipe coated with a lubricating medium into the ground. The advantages are that it does not affect the surrounding environment or has less impact, the construction site is small, and the noise is small. Moreover, it can work deep underground, which is an incomparable advantage of open-cut pipe burying. However, pipe jacking technology also has disadvantages, such as long construction time and high project cost. During construction, a support guide rail is required, and the construction tools move on the guide rail and carry out construction.

[0003] The comparative document (publication number CN208281627U) discloses an adjustable support guide rail used during pipe jacking construction, including two parallel tracks and legs. The two parallel tracks are connected by cross braces, and the length of the cross braces can be adjusted; a plurality of legs are correspondingly arranged on the two parallel tracks, one end of the legs is connected to the track and the other end supports on the ground, and the height of the legs can be adjusted.

[0004] When construction workers carry out construction on tunnel pipe jacking, as the construction progresses, they need to adjust the position of the tools accordingly. Generally, the support guide rail adopts a relatively fixed structure and needs to be disassembled accordingly according to the construction progress, which will bring certain troubles to pipe jacking construction, and frequent disassembly operations will occupy more working time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figures 1-6 A pipe jacking construction adjustable support guide rail includes a set of tracks with two cross guide rails 1. Upper protrusions 6 are provided on the upper sides of the two cross guide rails 1, lower protrusions 7 are provided on the lower sides of the two cross guide rails 1, a base 3 is slidably installed between the two cross guide rails 1, the base 3 is slidably connected to the lower protrusions 7, the two sets of tracks are connected by a connecting mechanism 4, and a plurality of holes 12 are formed in the lower protrusions 7;

[0028] The connecting mechanism 4 is installed on the upper projection 6. A clamping groove 9 is provided at the end of the cross guide rail 1, and the connecting mechanism 4 is installed on the clamping groove 9. The connecting mechanism 4 includes an I-shaped connecting piece 10. The four corners of the I-shaped connecting piece 10 are respectively clamped in the four clamping grooves 9. U-shaped shafts 8 are installed on the four corners of the I-shaped connecting piece 10. The I-shaped connecting piece 10 is fixedly connected to the cross guide rail 1 through the U-shaped shafts 8;

[0029] Adjusting mechanisms 5 are symmetrically arranged on the base 3. The adjusting mechanisms 5 are used to adjust the position of the base 3 on the cross guide rail 1. The adjusting mechanisms 5 include two sliders 17, and the sliders 17 are slidably installed on the base 3.

[0030] A connecting groove 13 is provided on the I-shaped connecting piece 10. One end of the U-shaped shaft 8 is provided with a first clamping shaft 14. The I-shaped connecting piece 10 includes an intermediate part and a corner part. The other end of the U-shaped shaft 8 is provided with a second clamping shaft 11. The first clamping shaft 14 is clamped on the intermediate part, and the U-shaped shaft 8 is clamped on the corner part. The two sets of tracks are fixedly connected together through the connecting mechanism 4. After the four corners of the I-shaped connecting piece 10 are respectively clamped at the corresponding positions of the clamping grooves 9, the U-shaped shafts 8 are installed on the four clamping grooves 9. One end of the U-shaped shaft 8 is clamped above the cross guide rail 1, and the other end is clamped at the lower position of the cross guide rail 1, so as to realize the fixing effect of the connecting mechanism 4 on the two cross guide rails 1.

[0031] Both ends of the second clamping shaft 11 are respectively inserted into two holes 12. The U-shaped shaft 8 is fixedly connected to the cross guide rail 1 through the second clamping shaft 11. The two ends of the U-shaped shaft 8 are respectively clamped on the upper surface and the lower surface of the cross guide rail 1, so as to realize the fixed connection between the I-shaped connecting piece 10 and the cross guide rail 1, and then realize the effect of extending the track.

[0032] Two openings 16 corresponding to the adjusting mechanism 5 are provided on the base 3. The range of the openings 16 covers at least three holes 12, and the sliders 17 are slidably connected relative to the openings 16. By controlling the sliders 17, the distance between the bottom plate 2 and the cross guide rail 1 is controlled, so as to realize the position adjustment of the bottom plate 2 on the cross guide rail 1.

[0033] A first side plate 21 is provided on one side of the base 3, and a second side plate 22 is symmetrically provided on the other side. The adjusting mechanism 5 further includes two cylinders 24. The two cylinders 24 are respectively fixedly installed on the first side plate 21 and the second side plate 22, and the positions of the two cylinders 24 are arranged staggeredly. The driving end of the cylinder 24 is fixedly connected with a driving shaft 15. The two driving shafts 15 are respectively fixedly connected to the two sliders 17. Magnetic shafts 20 are slidably inserted on the two sliders 17. The magnetic shafts 20 pass through the openings 16 and are inserted into the holes 12. The two cylinders 24 cooperate with each other to control the position of the sliders 17. The magnetic shafts 20 are installed on the sliders 17. By controlling the magnetic shafts 20, the position of the bottom plate 2 relative to the cross guide rail 1 is adjusted, and then the adjustment effect is realized.

[0034] An L-shaped shaft 19 is provided at one end of the slider 17, and an electromagnet 18 is mounted on the L-shaped shaft 19. The magnetic shaft 20 is used in conjunction with the electromagnet 18. When the electromagnet 18 is energized, it has an attractive or repulsive magnetic force on the magnetic shaft 20, so that the magnetic shaft 20 can be inserted into the hole 12 or taken out of the hole 12.

[0035] A protrusion 23 is provided on the slider 17 on one side of the magnetic axis 20, and a plurality of protrusions 23 are arranged staggered with each other. The end of the drive shaft 15 away from the cylinder 24 is fixedly connected to the protrusion 23 on the slider 17 at a farther position, and the L-shaped shaft 19 is fixedly connected to one side of the protrusion 23. The cylinder 24 controls different positions, so that the cross guide 1 can be moved relative to the base plate 2, and then the adjustment effect can be achieved. A buckle is provided on the side of the base 3 away from the adjustment mechanism 5. The tool can be installed on the base 3 through the buckle, and the base plate 2 can be moved relative to the cross guide 1, thereby moving the position of the tool, and flexibly performing pipe jacking construction.

[0036] The construction equipment is mounted on the base 3 by snap-fitting. When the construction tool needs to be moved, the position of the bottom plate 2 relative to the cross guide 1 is controlled by the adjusting mechanism to achieve the adjustment function. The four cylinders 24 are controlled to operate. First, the two cylinders 24 on the same side are controlled to remove the magnetic axis 20 connected to the cylinder 24 through the slider 17 from the hole 12, that is, the electromagnet 18 is energized to present a magnetic force opposite to the magnetic axis 20. The attraction of the electromagnet 18 on the magnetic axis 20 will cause the magnetic axis 20 to detach from the hole 12. The driving end of the cylinder 24 drives the slider 17 to move on the opening 16 through the driving shaft 15 and the protrusion 23, and the two sliders 17 are moved away from each other. The slider 17 is moved to the position of another hole 12, and then the current direction of the electromagnet 18 is changed so that the magnetic poles between the electromagnet 18 and the magnetic axis 20 are the same and repel each other, so that the magnetic axis 20 can be pushed into the hole 12.

[0037] Then move another magnetic axis 20, and adsorb the magnetic axis 20 through the corresponding electromagnet 18, so that the magnetic axis 20 is separated from the hole 12, and start the corresponding cylinder 24, which drives the slider 17 to move in the opening 16 through the driving shaft 15, and moves the magnetic axis 20 to another hole 12 accordingly, and then control the electromagnet 18 to repel the magnetic force of the magnetic axis 20, so as to insert the electromagnet 18 into the corresponding hole 12;

[0038] The two magnetic axes 20 complete the displacement within the range of the opening 16, and then the two cylinders 24 are started. The two cylinders 24 cooperate with each other to extend and retract, thereby driving the base 3 and the bottom plate 2 to move relative to the cross guide 1, and then realize the adjustment function, driving the corresponding construction tools to move.

[0039] When it is necessary to splice and extend the length of the track, place the four corners of the I-shaped connector 10 on the card slots 9 on the cross guide rail 1, and insert the U-shaped shaft 8 into the four corners. Insert the first card shaft 14 at one end of the U-shaped shaft 8 on one side of the I-shaped connector 10, and insert the second card shaft 11 at the other end of the U-shaped shaft 8 into the other side. Then insert the second card shaft 11 into the hole 12, thereby realizing the fixed connection between the I-shaped connector 10 and the cross guide rail 1.

[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
