Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A thin seam bolting jumbo 1000 according to an embodiment of the invention is described below with reference to the accompanying drawings. As shown in fig. 1 to 12, a thin coal seam bolting rig 1000 according to an embodiment of the present invention includes a vehicle body 100, a lifting device 110 and an anchor guard.

The lifting device 110 is installed at the front of the vehicle body 100. The anchoring device is connected to the lifting device 110 so that the lifting device 110 drives the anchoring device to move between a first anchoring position and a second anchoring position, and the first anchoring position is located below the second anchoring position. Namely, the first anchoring position is the lowest position to which the anchoring device can move under the driving of the lifting device 110, and the second anchoring position is the highest position to which the anchoring device can move under the driving of the lifting device 110. The distance between the upper edge of the anchor guard located at the first anchoring position and the lower edge of the vehicle body 100 in the vertical direction is less than or equal to a preset value. The distance between the upper edge of the anchor guard located at the first anchoring position and the lower edge of the vehicle body 100 in the vertical direction is smaller than or equal to a preset value, so that the anchor guard can move downwards to a lower position in the vertical direction. For example, the distance in the up-down direction between the upper edge of the anchor guard located at the first anchor guard position and the lower edge of the vehicle body 100 is 2m or less; the lower edge of the anchor guard located at the first anchoring position is located at a distance of 30cm from the lower edge of the vehicle body 100 in the up-down direction. The up-down direction is shown by arrow C in fig. 1.

The thin coal seam refers to a coal seam with the thickness of less than 1.3m when underground mining; the medium-thickness coal seam refers to a coal seam with the thickness of less than 2m during underground mining. The roadway height of the thin coal mining layer is between 2.3 and 2.8 meters. The distance between the upper edge of the anchoring device at the first anchoring position and the lower edge of the vehicle body 100 in the vertical direction is less than or equal to 2 meters, so that the thin coal seam anchor drill carriage 1000 according to the embodiment of the invention is suitable for anchoring the tunnel of the thin coal seam.

The height of the anchoring device in the up-down direction is greater than the height of the car body 100, so that the overall height of the thin seam anchor drill carriage 1000 can be adjusted by changing the position of the anchoring device in the up-down direction. When the roadway height is low (between 2.3 meters and 2.8 meters), the lifting device 110 can drive the anchoring device to move downwards to the first anchoring position by a certain distance, so that the distance between the upper edge of the anchoring device located at the first anchoring position and the lower edge of the vehicle body 100 in the vertical direction is less than or equal to a preset value (for example, the preset value is 2 meters). So as to reduce the overall height of the thin seam bolting jumbo 1000. Therefore, the overall height of the thin coal seam anchor rod drill carriage 1000 is smaller than the height of the roadway, the thin coal seam anchor rod drill carriage 1000 can conveniently enter the roadway with lower height, and the thin coal seam anchor rod drill carriage 1000 can smoothly reach the anchoring position. When the thin coal seam anchor rod drill carriage 1000 reaching the anchoring and protecting position anchors and protects the roadway, the anchor and protecting device can be driven to ascend to a proper height by the aid of the lifting device 110, so that workers can anchor and protect the top and the side wall of the roadway conveniently, and the anchoring and protecting efficiency is improved.

Therefore, the thin coal seam anchor rod drill carriage 1000 according to the embodiment of the invention has the advantages of low overall height, convenience in entering a roadway with lower height for anchoring and protection and improvement of anchoring and protection efficiency.

The invention also provides an anchoring and protecting device according to the embodiment of the invention. As shown in fig. 1 to 12, the anchoring and protecting device according to the embodiment of the present invention includes a front anchoring and protecting device 300, a rear anchoring and protecting device 400, and a working platform 200.

The front anchor guard 300 includes a front anchor guard mounting bracket and a front anchor guard boom 330, and the front anchor guard boom 330 is mounted on the front anchor guard mounting bracket. The rear anchor guard device 400 includes a rear anchor guard mounting bracket and a rear anchor guard boom mounted on the rear anchor guard mounting bracket.

That is, the distance between the front and rear anchor and

protection devices

300 and 400 at the first front anchor and protection position is greater than the distance between the front and rear anchor and

protection devices

300 and 400 at the second front anchor and protection position. That is, the anchor and guard device according to the embodiment of the present invention can adjust its entire length in the front-rear direction. The front anchor protection device 300 located at the second front anchor protection position is in a contraction state, and the distance between the front anchor protection device 300 in the contraction state (located at the second front anchor protection position) and the rear anchor protection device 400 is smaller, so that the cantilever of the anchor protection device in the contraction state, which is mounted on the anchor protection vehicle, is shorter, the center of gravity of the anchor protection vehicle moves backwards, and the anchor protection vehicle is convenient to walk. For example, the distance between the front anchoring device 300 and the rear anchoring device 400 at the first front anchoring position is 1 meter, so that the impact of the anchoring device in the contraction state on the center of gravity of the anchoring vehicle is small, and the anchoring vehicle can conveniently walk in a roadway.

The distance between the front anchor guard 300 and the rear anchor guard 400 at the first front anchor guard position is greater than or equal to a preset value, so that the distance between the front anchor guard 300 and the rear anchor guard 400 in the front-rear direction is relatively large, and therefore, a sufficient row spacing is formed between the front anchor guard 300 and the rear anchor guard 400 in the front-rear direction, and the front anchor guard 300 and the rear anchor guard 400 can perform anchoring work at the same time. The front anchoring device 300 is located between the first front anchoring position and the second front anchoring position (excluding the second front anchoring position), and the extended state can adjust the distance between the front anchoring device 300 and the rear anchoring device 400, so that the front anchoring device 300 and the rear anchoring device 400 have a proper row spacing. For example, when the front anchoring device 300 anchors a side wall and the rear anchoring device 400 anchors a cable, the distance between the front anchoring device 300 and the rear anchoring device 400 is greater than or equal to 1.5 m in the front-rear direction, so as to ensure that the front anchoring device 300 and the rear anchoring device 400 do not affect each other. When the front anchoring device 300 anchors the side anchor rods and the rear anchoring device 400 also anchors the side anchor rods, the distance between the front anchoring device 300 and the rear anchoring device 400 is greater than or equal to 2m in the front-rear direction, so that the front anchoring device 300 and the rear anchoring device 400 are not influenced mutually, and can work simultaneously, and the anchoring efficiency is improved.
