The anchor drill 300 is rotatably provided on the drill mount 200, and the rotation axis of the anchor drill 300 extends in a first horizontal direction (front-rear direction in fig. 2). That is, the jumbolter 300 is mounted on the drill mount 200, and the jumbolter 300 is rotatable about the rotation axis with respect to the drill mount 200.

The linear drive assembly 100 is coupled to the drill mount 200 to drive the drill mount 200 and the bolter 300 to move in a second horizontal direction (e.g., left-right direction in fig. 2), the first horizontal direction being perpendicular to the second horizontal direction.

The anchor drilling machine 300 according to the embodiment of the present invention can be moved in the second horizontal direction by the driving of the linear drive assembly 100, so that the anchor drilling machine 300 has a large supporting range for the roof of the roadway in the second horizontal direction.

Further, when the roof bolter 300 reaches the limit position in the second horizontal direction, the roof bolter 300 can be rotated about the rotation axis, and the rotation axis extends in the first horizontal direction, that is, the roof bolter 300 can be inclined to one side in the second horizontal direction, and thus, the range of the roof of the tunnel in the second horizontal direction supported by the roof bolter 300 is further increased.

Therefore, the anchor rod drilling machine 300 provided by the embodiment of the invention can support the top of the roadway in a large range, so that the stability of the roadway is improved, and the coal mine safety is facilitated.

In some embodiments, as shown in fig. 2-4, linear drive assembly 100 includes a fixed base 110, a movable base 130, and a first retractor 120.

The movable base 130 is disposed on the drill mounting base 200, and the movable base 130 is disposed on the fixed base 110 to be reciprocally movable in the second horizontal direction. That is, the drill mounting seat 200 and the movable seat 130 can reciprocate only left and right with respect to the fixed seat 110.

The first telescopic device 120 is connected to the fixed base 110, and the first telescopic device 120 is further connected to the moving base 130 to drive the moving base 130, the drill mounting base 200 and the jumbolter 300 to move in the second horizontal direction. That is, the roof bolter 300 moves left and right by the driving of the first telescopic link 120, whereby the roof bolter according to the embodiment of the present invention can support the top of the roadway in a wide range.

In some embodiments, as shown in fig. 2-4, the fixed base 110 and the movable base 130 are opposite in the first horizontal direction, and the first retractor 120 is located between the fixed base 110 and the movable base 130 in the first horizontal direction.

As shown in fig. 2 and 3, the fixed base 110 has two first slide slots 112 facing up and down, and the movable base 130 has two slide plates 132 facing up and down, the two slide plates 132 being engaged with the two first slide slots 112, respectively. Specifically, the notch of one first runner 112 is down and the notch of the other slide plate 132 is up. That is, at least a portion of the moving seat 130 is located between the two first sliding grooves 112 in the up-down direction. Further, the first retractor 120 is located between the fixed base 110 and the movable base 130 in the front-rear direction. Therefore, the linear driving assembly 100 has a small size in the front-rear direction, a compact structure, and space saving.

In some embodiments, as shown in fig. 2, the first retractor 120 includes a first body 121 and a first retractor 122, and the first retractor 122 is reciprocally disposed on the second body 411 along a length direction of the first body 121. The first body 121 is hinged to the fixed base 110, and the first telescopic member 122 is hinged to the moving base 130, so as to drive the moving base 130, the drill mounting base 200 and the jumbolter 300 to move in the second horizontal direction.

In some embodiments, as shown in fig. 2 and 4, the linear drive assembly 100 includes a first ear mount 111, a second ear mount 131, and a telescoping cavity.

As shown in fig. 2, the first ear seat 111 is disposed at one end of the fixing seat 110 in the length direction (e.g., the left end of the fixing seat 110 in fig. 2), the first body 121 is hinged to the first ear seat 111, and the length direction (e.g., the left-right direction in fig. 2) of the fixing seat 110 is parallel to the second horizontal direction. The fixing base 110 has a first groove 113. The first groove 113 is located on one side of the thickness direction of the fixing base 110 (e.g., the front side of the fixing base 110 in fig. 2), and the thickness direction of the fixing base 110 (e.g., the front-back direction in fig. 2) is parallel to the first horizontal direction. That is, the opening of the first groove 113 is directed forward. Specifically, the first groove 113 is located between the two first sliding grooves 112 of the fixing base 110 in the vertical direction.

As shown in fig. 4, the second ear seat 131 is disposed at one end of the moving seat 130 in the length direction (e.g., the right end of the moving seat 130 in fig. 4), the first telescopic member 122 is hinged to the second ear seat 131, and the length direction (e.g., the left-right direction in fig. 2) of the moving seat 130 is parallel to the second horizontal direction. The movable base 130 has a second groove 133. The second groove 133 is located at one side of the moving base 130 in a thickness direction (e.g., a rear end of the moving base 130 in fig. 4), and the thickness direction (e.g., a front-rear direction in fig. 4) of the moving base 130 is parallel to the first horizontal direction. That is, the opening of the second groove 133 faces rearward. Specifically, the second groove 133 is located between the two sliding plates 132 of the moving base 130 in the up-down direction.

That is, as shown in fig. 2 and 4, the first ear mount 111 and the second ear mount 131 face each other right and left. The first groove 113 and the second groove 133 are opposed in the front-rear direction, and a telescopic cavity is formed between the first groove 113 and the second groove 133. At least a portion of the first telescoping member 122 is located within the telescoping lumen.

As shown in fig. 4, a positioning block 134 is disposed in the second groove 133, and one side of the positioning block 134 adjacent to the fixing base 110 in the front-back direction has an arc-shaped surface. That is, the rear side of the positioning block 134 is an arc-shaped surface. The arc-shaped surface of the positioning block 134 can be attached to the outer peripheral surface of the first body 121 of the first telescopic device 120, the positioning block 134 can limit the first body 121, and the first body 121 and even the first telescopic device 120 can be prevented from swinging in the front-back direction or the up-down direction, so that the length direction of the first body 121 is parallel to the left-right direction, and the movable seat 130 is guaranteed to move in the left-right direction relative to the fixed seat 110. Therefore, the linear driving assembly 100 can be smoothly and stably operated.

According to the integrated machine of driving and anchoring of the embodiment of the present invention, the sliding plate 132 of the movable seat 130 is engaged with the first sliding slot 112 of the fixed seat 110, that is, at least a portion of the movable seat 130 is located in the fixed seat 110. In other words, when the fixed base 110 and the movable base 130 are fitted together, the dimension of the fixed base 110 and the movable base 130 in the front-rear direction is smaller than the sum of the dimension of the fixed base 110 in the front-rear direction and the dimension of the movable base 130 in the front-rear direction. The linear drive assembly 100 is therefore small in size in the front-rear direction. In addition, the first telescopic member 122 drives the movable seat 130 to move left and right relative to the fixed seat 110 in the telescopic cavity, when the first telescopic member 122, the fixed seat 110 and the movable seat 130 are fitted together, the first telescopic member 122 does not occupy extra space, and the size of the linear driving assembly 100 in the front-rear direction remains unchanged.

In some embodiments, as shown in fig. 1, 3-6, the jumbolter 300 includes a first jumbolter 310 and a second jumbolter 320. The first jumbolter 310 and the second jumbolter 320 are disposed opposite to each other in the left-right direction. That is, the first and second jumbolters 310 and 320 are rotatably mounted on the drill mount 200, with the first jumbolter 310 being located on the left side of the second jumbolter 320, or the second jumbolter 320 being located on the right side of the first jumbolter 310. The rotational axis of the first jumbolter 310 is parallel to the rotational axis of the second jumbolter 320, and both the rotational axis of the first jumbolter 310 and the rotational axis of the second jumbolter 320 extend in the front-rear direction.

It should be noted that the jumbolter according to the embodiment of the present invention is mounted on the frame of the machine and is located on the side of the cutting unit 002 of the machine in the left-right direction. That is, the jumbolter 300 of the embodiment of the present invention is located at the left or right side of the driving-anchoring all-in-one machine.
