Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydraulic supports, in particular to a self-moving unit support. Background Art
[0002] The safe production of coal mines is highly dependent on the stable support of the tunnels, which is the key line of defense to prevent the surrounding rock from becoming unstable, collapsing, or significantly deforming. Given the complex geological conditions commonly found in coal mine tunnels, such as uneven roof and floor plates and fragile roofs, timely support after excavation operations is particularly important. Currently, most coal mines use a single support system with a beam. During operation, most of these systems require manual disassembly and movement by workers. The manual movement of the supports is inefficient, significantly increasing the physical exertion and labor burden of the workers. At the same time, the installation and configuration of the supports is complex and tedious, increasing the difficulty of implementation. Some support systems exhibit insufficient stability under certain conditions, affecting the overall safety performance of the tunnels.
[0003] In the prior art, for example, the Chinese utility model patent with publication number CN221169625U discloses a lateral self-moving unit bracket, which specifically discloses a base, a column provided on the base, a top beam provided on the top of the column, a self-moving frame provided on the periphery of the base, an internal cavity of the self-moving frame forming a space for accommodating the base, a plurality of bottom lifting jacks provided on the self-moving frame, and the bottom lifting jacks used to lift the base off the bottom surface; a lateral movement cylinder and a pair of guide rods provided on the base, the two ends of the guide rods being connected to the self-moving frame, one end of the lateral movement cylinder being fixed to the base, and the other end of the lateral movement cylinder being connected to the self-moving frame. This lateral self-moving unit bracket does not require auxiliary handling equipment and can achieve self-lateral movement only by relying on the structure of the bracket itself. However, the lane is narrow, and it is difficult for transportation machinery and equipment to enter, and it is impossible to drag the bracket to move. In addition, the ground at the bottom of the lane is not wide, making it difficult for the bracket to move by itself. Summary of the Invention

[0022] See also Figures 1 to 3 ( Figures 1 to 3 All are for showing all features, not operation diagrams), the present application provides a self-moving unit bracket, including: a bracket body 100, a forward moving component 200 and a backward moving component 300, the bracket body 100 includes a column 120, a top beam 110, a base 130 and a side support jack 140, the two ends of the column 120 are respectively connected to the top beam 110 and the base 130, the side support jacks 140 are symmetrically arranged on both sides of the base 130, and the side support jacks 140 can be extended and retracted up and down in the vertical direction; the forward moving component 200 includes a front push jack 210, a front baffle 220 and a bottom plate 230, the fixed end of the front push jack 210 is connected to one end of the base 130 The telescopic end of the front pushing jack 210 is connected to the front baffle 220, one end of the bottom plate 230 is vertically connected to one end of the front baffle 220, and the bottom plate 230 is attached to the lower surface of the base 130 away from the top beam 110; and the rearward moving assembly 300 includes a rear pushing jack 310 and a rear support jack 320, the rear pushing jack 310 is arranged back to back with the front pushing jack 210, and the fixed end of the rear pushing jack 310 is connected to one end of the column 120 away from the top beam 110, the telescopic end of the rear pushing jack 310 is vertically connected to the fixed end of the rear support jack 320, and the rear support jack 320 can be telescoped up and down in the vertical direction.
[0023] Specifically, the top beam 110, column 120 and base 130 in the bracket body 100 can all adopt the hydraulic bracket commonly used in the prior art. The side support jacks 140 are connected to the side support jacks 140 on both sides through steel plates and other materials, and two side support jacks 140 are set on each side, and a pressure plate is set at the telescopic end of the side support jack 140; the fixed end of the front pushing jack 210 extends into the front end of the base 130 and is fixed by a pin or an installation barrel; the fixed end of the rear pushing jack 310 is connected to the column 120 by a frame, a pipe clamp, etc., and the front pushing jack 210 and the rear pushing jack 310 are set back to back.
[0024] Furthermore, when the self-moving unit support is supporting, the top beam 110 contacts the top of the tunnel and the base 130 contacts the bottom of the tunnel; when the self-moving unit support is moving, the column 120 contracts downward, causing the top beam 110 to move down and away from the top of the tunnel. After the column 120 contracts to a preset position, the side support jack 140 extends downward and contacts the bottom of the tunnel, causing the base 130 to be lifted and suspended, and the extension of the side support jack 140 is stopped. The front push jack 210 drives the front baffle 220 and the bottom plate 230 to move forward. After the front push jack 210 is extended to the limit stroke (the end of the bottom plate 230 away from the front baffle 220 does not extend out of the base 130), the side support jack 140 contracts upward The base 130 is brought into contact with the ground, and then the rear support jack 320 is extended downward and in contact with the bottom of the tunnel to complete the fixed support; at this time, with the front baffle 220 as the fulcrum, the front push jack 210 is retracted, pulling the base 130 to slide on the bottom plate 230 toward the end close to the front baffle 220; at the same time, with the rear support jack 320 as the fulcrum, the rear push jack 310 is extended, pushing the base 130 to move in the direction close to the front baffle 220; after the front support jack is retracted to its original position, the side support jack 140 is extended to lift the base 130, the front push jack 210 is extended, and the rear push jack 310 is retracted, and then the above steps are repeated until the self-moving unit bracket reaches the specified position.
[0025] This application adopts a technical solution of a self-moving unit bracket to achieve the following beneficial effects:
[0026] The forward moving component 200 and the backward moving component 300 provide the bracket body 100 with two fulcrums. The forward moving component 200 pulls the bracket body 100 and the backward moving component 300 pushes the bracket body 100, making the movement of the bracket body 100 more convenient and eliminating the need for other mechanical pulling, thereby solving the problem that narrow alleys are difficult for transport machinery and equipment to enter and cannot be dragged to move the bracket. At the same time, by providing a bottom plate 230 at one end of the front baffle 220, and the bottom plate 230 is in contact with the base 130, the problem that the bottom of the alley is not open and the bracket is difficult to move by itself is solved.
[0027] Based on the above solution, the rearward moving assembly 300 also includes a fixing frame 330, one end of which is connected to the telescopic end of the rear pushing jack 310, and the fixing frame 330 is connected to the fixed end of the rear supporting jack 320 away from the lower surface of the top beam 110.
[0028] The fixing frame 330 is a frame made of steel plates and other materials. The telescopic end of the rear push jack 310 extends into the fixing frame 330 and is connected together by means of a latch, a mounting barrel, etc. Similarly, a blind hole is provided at the bottom of the fixing frame 330, and the fixed end of the rear support jack 320 extends into the blind hole and is connected by means of a latch, a mounting barrel, etc.; by providing the fixing frame 330, the layout of the rear support jack 320 can be made more convenient, and the number can be increased according to the support needs, thereby making it more applicable.
[0029] In the above solution, at least one group of rear supporting jacks 320 is provided, and a stabilizing plate 340 is provided at the telescopic end of the rear supporting jacks 320 .
[0030] Two blind holes are provided at the bottom of the fixing frame 330, and a group of rear support jacks 320 are respectively provided in the two blind holes, and the telescopic ends of the two rear support jacks 320 are connected to the stabilizing plate 340. At the same time, the rear support jacks 320 are extended to drive the stabilizing plate 340 to descend until the stabilizing plate 340 contacts the bottom of the tunnel. By providing the stabilizing plate 340, the contact area between the rear support jacks 320 and the bottom of the tunnel is increased, making it more stable.
[0031] Based on the above solution, at least two groups of front push jacks 210 are provided, and the fixed ends of the front push jacks 210 are equidistantly provided at one end of the base 130 , and the telescopic ends of the front push jacks 210 are equidistantly connected to the front baffle 220 .
[0032] The front pushing jacks 210 are set according to the weight of the bracket. For example, three groups of front pushing jacks 210 are set and are set at equal intervals. The fixed ends and telescopic ends of the three front pushing jacks 210 are respectively connected to the base 130 and the front baffle 220. By setting up multiple front pushing jacks 210 and extending or contracting them at the same time, they have sufficient pulling force to drive the base 130 to move toward the direction close to the front baffle 220.
[0033] To achieve linear movement, the base 130 is provided with a slide groove at one end away from the top beam 110, and the slide groove is slidably connected to the bottom plate 230. The bottom plate 230 is provided with a slide rail, which is connected to the slide groove and can reciprocate along a predetermined trajectory along the slide groove.
[0034] Specifically, at least two slide grooves are provided on the base 130, and two slide rails are provided on the bottom plate 230, and the slide grooves and the slide rails are matched with each other. The slide rails are slidably connected in the slide grooves. When the front push jack 210 is extended, the front baffle 220 and the bottom plate 230 are driven to slide. At the same time, the slide rails slide in the slide grooves. Through the limitation of the slide rails and the slide grooves, the problem of difficulty in extension and retraction caused by the sliding offset of the bottom plate 230 when the front push jack 210 is extended is solved.
[0035] Based on the above scheme, the rearward movement assembly 300 also includes a sleeve 350 and a clamp 360. The sleeve 350 is sleeved on the end of the column 120 away from the top beam 110 and is detachably connected to the base 130. The fixed end of the rearward push jack 310 is connected to the sleeve 350. The clamp 360 is arranged on the end of the sleeve 350 away from the base 130 and is used to fix the sleeve 350 on the column 120.
[0036] Specifically, the inner diameter of the sleeve 350 is the same as the outer diameter of the end of the column 120 away from the top beam 110. The sleeve 350 is sleeved onto the column 120, and one end is detachably connected to the base 130 by means of threads, snaps, or other means. The clamp 360 surrounds the sleeve 350 and the column 120, securing the sleeve 350 to the column 120 and preventing the sleeve 350 from rotating or detaching from the base 130. The fixed end of the rear push jack 310 is connected to the side wall of the sleeve 350. By raising the thrust point between the rear push jack 310 and the bracket body 100, the rear push jack 310 is more convenient to push and has better stability, solving the problem of difficulty in self-movement caused by the thrust point being too low or too high.
[0037] The above-described embodiments only express the way in which the equipment of the present application is arranged. The description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that a person skilled in the art can make a number of adjustments and improvements without departing from the concept of the present application, and these all fall within the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application shall be based on the attached claims.
