Description

[0001] The invention relates to the technical field of mining, and in particular to an advanced crawler type walking support device. Background Art

[0002] The advanced section of the working face generally adopts two methods: single hydraulic support with metal top beam support or advanced hydraulic support. The support strength of single hydraulic support is limited. In areas where the mine pressure is strong, the support strength it provides is often difficult to meet the requirements and cannot resist the sinking of the roof and the deformation of the surrounding rock; in areas with softer bottom plates, single pillars are easy to drill the bottom, and the support and withdrawal speed is slow, which restricts the advancement speed of the working face; support and withdrawal mainly rely on manpower, and the labor intensity of workers is high. The advanced hydraulic support support has poor adaptability to the roof. When the roof has poor integrity, unevenness or local crushing, the rigid top beam and the roof are not well fitted, which can easily cause further crushing of the roof, which is not conducive to the safe management and maintenance of the roof, and at the same time threatens the life safety of workers and equipment safety; during the frame shifting process, especially the step-by-step advanced hydraulic support, it will go through repeated frame lowering and frame shifting processes, which will repeatedly support the tunnel roof, which may cause the roof to loosen and delaminate, affecting the stability of the roof, and is not conducive to the realization of automated frame shifting.

[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] The following describes the advanced crawler type walking support device of the embodiment of the present invention with reference to the accompanying drawings. Figures 1 to 3 As shown, the leading-section crawler-type walking support device according to an embodiment of the present invention includes a top beam 1 and two chassis 2.

[0026] The length direction of the chassis 2 is the first direction, and the width direction of the chassis 2 is the second direction. Any two of the first direction, the second direction and the up-down direction are perpendicular to each other. The two chassis 2 are spaced apart in the second direction, each chassis 2 is provided with a crawler walking part 3 at one end of the second direction, and each chassis 2 is provided with a slide rail moving part 4 at the other end of the second direction. The slide rail moving parts 4 on the two chassis 2 are located between the two chassis 2 in the second direction. The two slide rail moving parts 4 can be (respectively) matched on the two slide rails in the lane. The crawler walking parts 3 on the two chassis 2 are located outside the two chassis 2 in the second direction. Specifically, crawler walking parts 3 and slide rail moving parts 4 are respectively provided on both sides of the width direction of the chassis 2. The slide rail moving parts 4 can be matched on the slide rails in the lane. The crawler walking parts 3 are connected to the bottom plate in the lane. The crawler walking parts 3 and the slide rail moving parts 4 cooperate to drive the chassis 2 to move in the lane. The two chassis 2 are spaced apart in the width direction thereof, and the two chassis 2 can move in the lane along the extension direction of the slide rail. The first direction may be a front-rear direction, and the left-right direction may be a left-right direction. For example, the slide rail moving part 4 on the two chassis 2 is located between the two chassis 2 in the left-right direction, and the crawler walking part 3 on the two chassis 2 is located outside the two chassis 2 in the left-right direction.

[0027] Each chassis 2 is provided with a plurality of hydraulic columns 5, the telescopic parts of the hydraulic columns 5 can be extended upward, and the top of the telescopic parts of the hydraulic columns 5 is connected to the bottom of the top beam 1. The top beam 1 is plate-shaped and is used to support the top plate of the tunnel. Thus, the two chassis 2 can drive the hydraulic columns 5 and the top beam 1 thereon to move in the tunnel through the crawler walking part 3 and the slide rail moving part 4. The top beam 1 can connect the two chassis 2. For example, the top beam 1 is a rectangular plate.

[0028] In some embodiments, the telescopic portion of each hydraulic column 5 is hinged to the top beam 1 , so that the top beam 1 can be tilted relative to the hydraulic column 5 by controlling the extension length of the telescopic portion of the hydraulic column 5 , thereby facilitating the top beam 1 to support the top plate.

[0029] In some embodiments, the telescopic portion of each hydraulic column 5 is movably connected to the top beam 1. Thus, the top beam 1 can be tilted in multiple directions relative to the hydraulic column 5 by controlling the extension length of the telescopic portion of the hydraulic column 5, so as to facilitate the top beam 1 to support the top plate. For example, a first connecting buckle is provided on the telescopic portion of each hydraulic column 5, and a plurality of second connecting buckles are provided at the bottom of the top beam 1, and the first connecting port is connected to the corresponding second connecting buckle, and the first connecting buckle can move relative to the second connecting buckle.

[0030] like Figure 2As shown, in some embodiments, at least two hydraulic columns 5 are provided on each chassis 2. The multiple hydraulic columns 5 on each chassis 2 are arranged at intervals in the first direction. Specifically, two hydraulic columns 5 are provided on each chassis 2, and the two hydraulic columns 5 on each chassis 2 are arranged at intervals in the first direction, and the two hydraulic columns 5 on one of the two chassis 2 are arranged opposite to the two hydraulic columns 5 on the other in the second direction. For example, the two hydraulic columns 5 on each chassis 2 are arranged at intervals in the front-to-back direction, and the two hydraulic columns 5 on one of the two chassis 2 are arranged opposite to the two hydraulic columns 5 on the other in the left-to-right direction, that is, the four hydraulic columns 5 on the two chassis 2 are arranged in a matrix.

[0031] In some embodiments, each chassis 2 is provided with a plurality of placement holes, each placement hole penetrates the chassis 2 in the up-down direction, and the fixed parts of the plurality of hydraulic columns 5 are movably arranged in the plurality of placement holes in a one-to-one correspondence in the up-down direction. Each chassis 2 is provided with a first driving assembly, the first driving assembly includes a first driving hydraulic rod, the telescopic part of the first driving hydraulic rod is connected to the fixed part of the corresponding hydraulic column 5 through a driving connector, and the telescopic part of the first driving hydraulic rod can drive the fixed part of the hydraulic column 5 connected thereto to move downward to the bottom of the chassis 2 and connect with the ground (tunnel floor). Therefore, when the advanced crawler-type walking support device moves to the support position, the telescopic part of the first driving hydraulic rod can drive the fixed part of the hydraulic column 5 connected thereto to move downward and connect with the ground, thereby facilitating the support of the hydraulic column 5.

[0032] In some embodiments, each chassis 2 includes a first chassis and a second chassis, and the first chassis and the second chassis are arranged side by side in the second direction. The first chassis 2 is connected to the crawler walking part 3, the second chassis 2 is slidably connected to the first chassis 2 in the up and down directions, the second chassis 2 is connected to the slide rail moving part 4, and the hydraulic column 5 is arranged on the second chassis 2. A second driving assembly is provided on each first chassis 2, and the second driving assembly includes a second driving hydraulic rod, the telescopic part of the second driving hydraulic rod is connected to the second chassis 2, and the second chassis 2 of the second driving hydraulic rod moves downward and connects with the ground. Therefore, when the leading crawler walking support device moves to the support position, the second chassis 2 of the second driving hydraulic rod moves downward and connects with the ground, so as to facilitate the support of the hydraulic column 5.

[0033] In some embodiments, a vibration reduction device is provided between the hydraulic column 5 and the chassis 2. The vibration reduction device includes a multi-layer rubber vibration reduction pad and a hydraulic damper. The rubber vibration reduction pad can effectively absorb high-frequency vibrations, and the hydraulic damper can suppress low-frequency and large-amplitude vibrations. Through this combination, the influence of the vibrations generated by the movement of the leading section top plate and the deformation of the surrounding rock on the hydraulic column 5 and the entire support device can be greatly reduced, the stability of the support in a complex environment can be ensured, and the safety of the leading section support operation can be improved.

[0034] In some embodiments, the two slide rail moving parts 4 can be matched with the slide rails on both sides of the width direction of the transfer machine 6 in the lane, and the two slide rail moving parts 4 can be matched with the slide rails on both sides of the width direction of the transfer machine 6 so that the two chassis 2 can move along the extension direction of the transfer machine 6. That is, the advanced crawler walking support device of the present invention can move in the lane using the slide rails of the transfer machine 6 in the lane.

[0035] In some embodiments, the slide rail moving part 4 includes a pulley, and the pulley can be matched on the slide rail of the transfer machine 6.

[0036] In some embodiments, the leading crawler-type walking support device includes a fixing frame, and the fixing frame is detachably connected to the two chassis 2 at both ends in the second direction. Therefore, after the leading crawler-type walking support device is off the track, the fixing frame can be connected to the two chassis, thereby improving the stability of the movement of the leading crawler-type walking support device. For example, the fixing frame is provided with fixing screw holes at both ends in the second direction, and the chassis 2 is provided with chassis screw holes on the top surface, and the fixing frame and the chassis 2 can be detachably connected by passing through the studs penetrating the fixing screw holes and the chassis screw holes.

[0037] The advanced crawler-type walking support device according to the embodiment of the present invention can easily drive the hydraulic column 5 and the top beam 1 to move in the tunnel through the crawler walking part 3 and the slide rail moving part 4, thereby improving the support efficiency. It can also cooperate with other equipment (transfer machine, crusher, self-moving tail, etc.) in space and operation process, which can reduce the safety hazards caused by mutual interference.
