Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to a method and device for laying a track for slag transportation in a steep and long-distance inclined shaft. Background Art

[0002] With the increasing number of long and large tunnels being built in my country, in order to solve the problem of tunnel ventilation, tunnel construction often encounters difficulties such as large height differences, steep slopes, and long distances. The method of "long tunnels and short construction" through inclined shafts is usually adopted to ensure the construction period. In the past, during construction, an excavator loader was usually used to load the bucket on the working surface, which was then towed to the intersection of the main and branch tunnels by an electric vehicle via a track. The bucket was then towed to the outside of the branch tunnel by a winch at the branch tunnel entrance. The slag was then concentrated on the slag unloading platform and finally loaded onto a dump truck by a loader and transported to the slag dump. The traditional process has the following problems: large capital investment in construction equipment, complicated auxiliary facilities, difficult maintenance, a large number of auxiliary construction personnel, secondary transportation of slag at the branch tunnel entrance, and low emergency response capabilities in the event of sudden geological disasters in the tunnel. In order to solve the above problems, the existing technology lays tracks in the inclined shaft and uses a transport vehicle to directly travel on the tracks to transport tunnel slag. However, this method requires laying tracks in the inclined shaft in advance, and the space in the inclined shaft is small. Traditional tunnel track laying equipment is difficult to use in the narrow inclined shaft. Therefore, the technology has so far adopted manual laying with auxiliary tools, which is too slow. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a track laying device for slag transportation in a large-slope and long-distance inclined shaft.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment discloses a method for laying a track for transporting slag in a large-slope and long-distance inclined shaft. First, the bottom surface 100 of the inclined shaft needs to be arranged, leveled and compacted, and then a plurality of positioning holes 300 are dug on the bottom surface 100 of the inclined shaft. The positions of the positioning holes 300 are opened according to the length of the track 200. When laying the track, the first group of tracks 200 are laid manually, and the locator 3 at one end of the track 200 is placed into the positioning hole 300, and the track 200 is compacted. In this way, the laying device can move on the laid first group of tracks 200. The laying device can then lay the second group of tracks, the third group of tracks... until the Nth group of tracks downward along the bottom surface 100 of the inclined shaft.

[0025] See also Figures 2 to 10 As shown, the above-mentioned large-slope long-distance inclined shaft slag transportation track laying device includes a base plate 1, a rail car 10 is installed on the lower side of the base plate 1, and the front end of the base plate 1 extends to the outside of the rail car 10 to facilitate the installation of the track 200. The base plate 1 can move on the track 200 through the rail car 10. At the same time, a track clamp is installed on the rail car 10. After the track clamp is clamped on the track 200, the base plate 1 can be stabilized on the track 200, and can effectively prevent the base plate 1 and the track 200 from relative displacement. After the track clamp is released, the base plate 1 can move on the track 200. The track clamp is a prior art and will not be described here.

[0026] A chute 11 is provided on the upper side of the base plate 1, and a slide 12 is slidably connected within the chute 11. A drive device for driving the slide 12 to slide is mounted on the base plate 1. The drive device includes a screw 16, which is rotatably connected within the chute 11. A power motor 17 is mounted on one side of the base plate 1 to drive the screw 16. A screw nut is fixedly connected to the slide 12, and the screw 16 is threadedly connected within the screw nut. In this way, the power motor 17 drives the screw 16 to rotate clockwise or counterclockwise, and the transmission force between the screw 16 and the screw nut can cause the slide 12 to reciprocate within the chute 11.

[0027] The flip block is hinged inside the slide 12. A flip motor 18 is installed on one side of the slide 12 to drive the flip block to rotate. The way the flip motor 18 drives the flip block is existing technology and will not be described in detail here. A hydraulic cylinder 13 is installed on the flip block. Two guides 2 are provided on the base plate 1. Two rails 200 slide one by one on the guides 2. The guides 2 include a fixed plate 21. The fixed plate 21 is fixed to the upper side of the base plate 1. One side of the fixed plate 21 is rotatably connected to an "L"-shaped guide plate 22. A lubricating liquid injection device 23 is installed on one side of the fixed plate 21. The lubricating liquid injection device 23 is used to spray lubricating liquid on the surface of the guide plate 22, which helps the rail 200 slide on the upper side of the guide plate 22. The lubricating liquid injection device 23 is existing technology and will not be described in detail here. A fixed rod 14 is fixedly connected between the two rails 200. The telescopic end of the hydraulic cylinder 13 is hinged to the electromagnetic clamp 15. The electromagnetic clamp 15 is adsorbed and fixed to the fixed rod 14.

[0028] A locator 3 is hinged to the lower side of one end of each track 200. The locator 3 can be inserted into the positioning hole 300 of the bottom surface 100 of the inclined shaft to locate the position of the track 200 and prevent the track 200 from tilting on the bottom surface 100 of the inclined shaft. The locator 3 includes a positioning block 30, and a mounting groove 32 is provided on the upper side of the positioning block 30. The mounting groove 32 is hinged to the fixing seat 5 through the hinge shaft 52, and the fixing seat 5 is fixed to the track 200. A placement groove 31 is provided at the bottom of the positioning block 30, and a sliding hole connected to the placement groove 31 is provided at the bottom of the mounting groove 32. A reinforcing rod 33 is slidably connected in the sliding hole. The upper end of the reinforcing rod 33 is fixedly connected to the struck block 35, and the lower end of the reinforcing rod 33 is fixedly connected to the anchor rod head 34. A clearance groove 36 is provided at the upper end of the sliding hole, and the struck block 35 can enter the clearance groove 36. The lower side of the track 200 is fixedly connected to the striking block 4, and the striking block 4 is arranged corresponding to the struck block 35. One side of the striking block 4 is slidably connected to the insertion rod 6. A socket 51 is provided on one side of the fixed seat 5, and the insertion rod 6 can be inserted into the socket 51. An adaptation device is provided in the striking block 4, and the adaptation device is used to drive the insertion rod 6 to translate and insert it into the socket 51. A cavity is set in the striking block 4, and the insertion rod 6 slides in the wall hole of the cavity. The part of the insertion rod 6 located in the cavity is fixedly connected to the rack 61. The adaptation device includes a rotating shaft 71 rotatably connected to the inner wall of the cavity. The rotating shaft 71 is connected to the inner wall of the cavity through a one-way rotating bearing. The one-way rotating bearing is a prior art and is used to limit the rotating shaft 71 to only one-way rotation. A coaxially arranged gear 72 and a ratchet 73 are fixedly connected to the rotating shaft 71. The gear 72 is meshed with the rack 61. A through groove running through the striking block 4 is provided at the bottom of the cavity. A vertical rod 74 is slidably connected in the through groove. A plurality of ratchets 75 are installed on the vertical rod 74. The ratchet teeth 75 can push the ratchet 73 to rotate.

[0029] When the above-mentioned large-slope long-distance inclined shaft slag transportation track laying device is used, see Figure 2First, place the track 200 above the substrate 1 so that the track 200 is located on the upper side of the guide plate 22. The fixing rod 14 between the track 200 is fixed by the electromagnetic clamp 15. At this time, the track 200 and the substrate 1 are in a parallel state. The substrate 1 is driven forward along the track 200 by the track car 10. When it reaches the appropriate position, the track clamp clamps the track 200, and the substrate 1 is temporarily fixed. The driving device drives the slide 12 forward in the slide groove 11. When the positioner 3 at one end of the track 200 is aligned with the positioning hole 300, see Figure 9 and Figure 10 , the flip motor 18 drives the flip block to rotate, thereby rotating the hydraulic cylinder 13. At this time, the track 200 also rotates accordingly, thereby placing the locator 3 into the positioning hole 300. Then the track clamp is released, and the base plate 1 moves backward. During the process of the base plate 1 moving backward, the telescopic end of the hydraulic cylinder 13 extends, so that the electromagnetic clamp 15 and the fixed rod 14 remain relatively stationary. The purpose of moving the base plate 1 is to provide space for the track 200 to fall under its own gravity. After the above conditions are met, the electromagnetic clamp 15 releases the fixed rod 14. At this time, the track 200 rotates downward due to the loss of the adsorption force of the electromagnetic clamp 15 and is laid on the bottom surface 100 of the inclined shaft. Then, the electromagnetic clamp 15 adsorbs the fixed rod 14, lifts the track 200 upward, and then puts it down. By lifting and putting down the track 200 multiple times, the track 200's own gravity is used to compact the bottom surface 100 of the inclined shaft and align the track 200 with the track 200 behind.

[0030] In order to improve the strength of the track 200 after it is laid, when the track 200 falls due to gravity multiple times, the striking block 4 on the track 200 can just hit the struck block 35, and the struck block 35 moves downward, thereby causing the reinforcement rod 33 to move downward and the anchor head 34 to be inserted into the soil at the bottom of the positioning hole 300. In this way, the anchor head 34 acts as an anchor. After the track 200 is laid, concrete slurry is injected into the positioning hole 300, and the concrete slurry will also enter the placement groove 31. After the concrete slurry solidifies, the locator forms a whole with the surrounding geology, thereby improving the strength of the track 200 after it is laid. In order to align the front and back of the track 200 after laying, when the track 200 falls due to gravity, the vertical rod 74 will also hit the upper side of the positioning block 30, so that the vertical rod 74 will move upward, and under the action of the ratchet 75, the ratchet 73 will rotate. The rotation of the ratchet 73 will drive the gear 72 to rotate. Under the meshing force of the gear 72 and the rack 61, the insertion rod 6 will gradually translate forward and finally be inserted into the insertion hole 51. After the insertion rod 6 is inserted into the insertion hole 51, it is proved that the track 200 has been laid in place and the front and back are aligned. At this time, the track 200 cannot move anymore, so the front and back tracks can be laid neatly. In addition, by inserting the insertion rod 6 into the insertion hole 51, the front and back tracks are connected as a whole, which can enhance the stability of the track laying to a certain extent.
