Description

Technical Field

[0001] The invention belongs to the technical field of lining trolleys, and in particular relates to a traveling device of a hydraulic lining trolley in an underground coal mine. Background Art

[0002] Lining trolley, full name tunnel lining trolley, is a special equipment that must be used in the secondary lining of the tunnel construction process. It is mainly used for the concrete lining construction of the inner wall of the tunnel, and is also used for the pouring of secondary lining (secondary lining) concrete for tunnels, diversion tunnels, etc.

[0003] Some invention patents in the field of lining trolley technology are disclosed in the prior art, among which the patent with publication number CN212535692U discloses a walking device of a fully automatic lining trolley, including a lining trolley body, a slide rail, a cleaning structure, a mounting shell, a cleaning rod, a mounting rod, a cleaning brush and a driving structure. The top side of the slide rail used to guide the lining trolley in this technical solution is a "human" shaped inclined surface structure, so that when the falling rock particles are large, they will roll down directly, and when the falling rock particles are small, they will accumulate on the surface of the slide rail. Two symmetrically arranged cleaning rods are arranged inside the mounting shell arranged at the traveling end of the lining trolley body, and a rotatably connected mounting rod is provided at the end of the cleaning rod. The cleaning brush fixed on the other side of the mounting rod can The surface of the slide rail is cleaned, and when the mounting rod rotates, due to the inclined structure of the top side of the slide rail, the cleaning brush can remain close to the surface of the slide rail, thereby achieving the best cleaning effect, effectively sweeping away the fine particles on the surface of the slide rail, and avoiding the accumulation of gravel on the surface of the slide rail to hinder the movement of the lining trolley. This technical solution still has some shortcomings in the process of application. The cleaning method of the walking mechanism of the lining trolley is relatively single. Since the track is mostly solidified concrete, the concrete used in coal mines has high strength and strong adsorption capacity. The cleaning effect of relying solely on a cleaning brush is limited, and concrete structure residues are prone to appear, which not only easily accelerates the wear of the trolley walking mechanism, but also is prone to downtime or delays due to track problems.

[0004] Based on this, the present invention designs a traveling device of a hydraulic lining trolley in an underground coal mine to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the existing lining trolley's traveling mechanism has a relatively single cleaning method.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, during the process of the second unfolding plate and the first unfolding plate being folded backward, the two second elastic bands will respectively pull the track cleaning tools connected thereto to unfold. Since two adjacent track cleaning tools are connected by multiple first elastic bands, the process of the two outermost track cleaning tools unfolding backward will drive multiple track cleaning tools to unfold synchronously. The air in the assembly disk is sucked into the piston cylinder. As the air is sucked into the piston cylinder, the low pressure strength in the piston cylinder gradually weakens, and the first pressure spring starts to perform elastic reset movement. Under the push of the first pressure spring, the first sealing plug re-enters the first bucket-shaped cover. The knob is twisted again until the upper wedge-shaped seat is completely reset. Since the assembly disk and the piston rod are connected by a rotating connection The track cleaning tools are connected to each other, so the multiple track cleaning tools after deployment will be able to swing in a circle around the assembly disc, thereby achieving the effect of flexible switching of the track cleaning tools and convenient management. In the process of the track cleaning tool group gradually deploying from both sides to the inside, the outer track cleaning tool moves downward before the inner track cleaning tool, thereby achieving the effect of cutting the concrete agglomerates on the track and realizing multiple scraping cleaning. The clean track can reduce the wear on the trolley running mechanism, thereby extending its service life, slowing down the wear of the running wheels and bearing components of the trolley running mechanism, and reducing the cost of maintenance and replacement. Keeping the track clean can ensure that the trolley runs smoothly and smoothly, avoid downtime or delays caused by track problems, thereby improving operating efficiency.

[0016] 2. In the present invention, when the slide plate slides downward, it will drive the supporting spring connected to it to undergo elastic deformation. Since the third elastic band has a certain elasticity, when the slide plate pulls two adjacent slide plates through two groups of third elastic bands, the descending distance of the slide plate is smaller than the descending distance of the slide plate. Similarly, the descending distance of the outer slide plate gradually decreases, so that the descending distances of the two adjacent track cleaning tools are different.

[0029] Working principle, when using: The two outermost rail cleaning cutters 2033 are elastically connected to the first unfolding plate 101 and the second unfolding plate 103 respectively by using two second elastic bands 206. In the initial state, the second unfolding plate 103 is in a closed state. At this time, the first adapter frame 104 is rotatably connected to one end of the hydraulic cylinder through the first adapter 105, and the second adapter frame 106 is rotatably connected to the other end of the hydraulic cylinder through the second adapter 107. The hydraulic cylinder is controlled to retract to open the first unfolding plate 101 and the second unfolding plate 103. The first adapter frame 104 is separated from the first adapter 105, and the hydraulic cylinder is continuously controlled to retract to make the first unfolding plate 101 and the second unfolding plate 103 fold backward around the bridging plate 102. In this process, the bridging plate 102 and the rear pad 201 will undergo elastic deformation, and the planar structure will be transformed into a curved structure. The external drive device twists the assembly disk 505, and the assembly disk 505 drives the external thread 506 to rotate in the threaded opening. The assembly disk 505 extends downward in the threaded opening. When the external thread 506 is completely out of the threaded opening, the assembly disk 505 moves out of the threaded opening. In this process and subsequent stages, the piston rod 503 stretches in the piston cylinder 502 under the elastic thrust of the piston spring 504. During the stretching movement of the piston rod 503 and the piston cylinder 502, the pressure in the piston cylinder 502 will gradually decrease and form a low-pressure environment in the piston cylinder 502. Then slowly twist the knob 6065, and the knob 606 The threaded cylinder 6064 is driven to rotate on the threaded surface of the threaded rod 6063, and the threaded rod 6063 retracts in the threaded cylinder 6064, driving the upper wedge seat 6062 to slide on the inclined surface of the lower wedge seat 6061. The downward pressure exerted by the upper wedge seat 6062 on the lower wedge seat 6061 gradually weakens. Under the action of the low-pressure environment, the first sealing plug 602 moves upward. On the one hand, the first sealing plug 602 slides upward in the first mesh plate 604 through the first sliding rod. On the other hand, the first sealing plug 602 is separated from the first bucket cover 601, and the first pressure spring 605 is gradually squeezed and compressed; When the piston rod 503 stretches in the piston cylinder 502, the piston rod 503 will pull down the second tooth plate 904 through the transmission frame 905, and the second tooth plate 904 will move on the gear 903, and the gear 903 will rotate. Under the rotation of the gear 903, the first tooth plate 902 moves upward, and the first tooth plate 902 will drive the docking plate 10 to move upward through the transmission seat 901 during the upward movement. During the upward movement of the docking plate 10, the slide plate 2031 connected thereto will be driven to slide in the slide groove 202, and the track cleaning tool 2033 connected to the slide plate 2031 will slide downward. During the downward sliding process of the slide plate 2031, the two third elastic bands will be pulled by the two third elastic bands. The adjacent skateboards 2031 move upward, since each skateboard 2031 is elastically supported by the supporting spring 2032 connected to it, and the third elastic band also has a certain elasticity, the skateboard 2031 will drive the supporting spring 2032 connected to it to undergo elastic deformation during the downward sliding process. Since the third elastic band has a certain elasticity, when the skateboard 2031 pulls the two adjacent skateboards 2031 through the two groups of third elastic bands, the descending height of the skateboard 2031 is less than the descending height of the skateboard 2031. Similarly, the descending height of the outer skateboard 2031 gradually decreases, so that the descending heights of the two adjacent track cleaning tools 2033 are different.

[0030] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
