An operator can easily stand on the side position standing person platform 14 at this time, and the connecting rod 16 rotates upwards to drive the side position standing person platform 14 to move upwards.

Until the connecting rod 16 rotates to the limit position, namely, the connecting rod 16 connected with the mounting frame 15 is in the horizontal state, the connecting rod 16 connected with the connecting plate 17 is in the vertical state, and the connecting plate 17 reaches the highest position, namely, the side station people platform 14 reaches the highest position. The space occupied by the connecting rod 16 is the smallest at this time, and the connecting rod is almost attached to the outer side of the rotating base 1. When side station personnel platform 14 is not needed, power means may drive side station personnel platform 14 to fold downwardly relative to web 17 so that side station personnel platform 14 is in an upright position and outside of links 16. The lateral standing platform 14 is in a contracted state at this time, and the whole volume is small.

The power device comprises a second power cylinder 18, the second power cylinder 18 is arranged on one side surface of the mounting frame 15, and the second power cylinder 18 is connected with the connecting rod 16 through a torsion arm 19. The second cylinder 18 is operated to rotate the torque arm 19, and the rotating torque arm 19 rotates the connecting rod 16.

Four arm stock drill carriages, as shown in fig. 3, include base 21 and install two side position change mechanisms in base 21 front end, and two side position change mechanisms are close to the both sides setting of base 21 respectively.

In some embodiments of the present application, the front end of the base 21 is provided with two middle position changing mechanisms, and the two middle position changing mechanisms are located between the two side position changing mechanisms.

Based on the foregoing embodiment, another embodiment is provided, as shown in fig. 4 and 5, the middle position changing mechanism includes a connecting seat 23 disposed at the front end of the base 21, and the connecting seat 23 is rotatable relative to the base 21; the middle drill arm 22 is arranged on the connecting seat 23, and the middle drill arm 22 can swing relative to the connecting seat 23; the swinging of the middle drill boom 22 can adjust the angle of the side drill boom 5 in the roadway cross section, and the position of the roadway top surface is selected. The connecting seat 23 rotates to drive the middle drill boom 22 to rotate, and the middle drill boom 22 can rotate to be parallel to the base 21. In the retracted state, the connecting socket 23 can then drive the middle boom 22 to rotate, and when the middle boom 22 is rotated to be parallel to the base 21, the height of the middle boom 22 is at the minimum, and the overall rock bolting rig is small, which is the preferred retracted position. The rotation of the connecting seat 23 can drive the middle drill boom 22 to adjust the angle in the front-back direction of the roadway, so as to select the position of the top surface of the roadway.

In some embodiments of the present application, the middle drill boom 22 is vertically disposed on the connecting base 23, and the power device is operated to drive the middle drill boom 22 to swing in a plane perpendicular to the plane of the connecting base 23.

In the present application, the middle drill arm 22 and the connecting seat 23 are arranged perpendicular to each other, which is a preferred structure. When the connecting seat 23 moves to the horizontal state, the middle drill arm 22 is in the vertical state; when the connecting base 23 is turned backwards to be in a vertical state, the middle drill arm 22 is located above the base 21 and is in a horizontal state.

The power device comprises a third power cylinder 24, one end of the third power cylinder 24 is arranged on the connecting seat 23, and the third power cylinder 24 can rotate relative to the connecting seat 23; the other end of the third power cylinder 24 is connected to the middle drill boom 22, and the third power cylinder 24 is rotatable with respect to the middle drill boom 22. When the third power cylinder 24 is extended or shortened, the middle drill boom 22 can be driven to swing left and right.

Based on the previous embodiment, another embodiment is provided, in which the front end of the base 21 is provided with a connecting frame 25, the connecting seat 23 is connected with the base 21 through the connecting frame 25, and the connecting seat 23 is rotatable relative to the connecting frame 25.

The connecting frame 25 is further connected with a front leg 26, and the front leg 26 can rotate relative to the connecting frame 25. In particular, the front leg 26 may be used to support a rock bolt drill carriage when rotated perpendicular to the base 21. When the front leg 26 is rotated to be parallel to the base 21, the front leg 26 is in a contracted state. Specifically, the connecting seat 23 is connected to an upper end of the connecting frame 25. The front leg 26 is connected to the lower end of the link frame 25.

The power device comprises a fourth power cylinder 27, one end of the fourth power cylinder 27 is arranged on the connecting frame 25, and the fourth power cylinder 27 can rotate relative to the connecting frame 25; the other end of the fourth power cylinder 27 is connected to the front leg 26, and the fourth power cylinder 27 is rotatable with respect to the front leg 26. When the fourth power cylinder 27 is extended or shortened, the front support leg 26 can be driven to be in a supporting or contracting state.

In some embodiments of the present application, the present application further comprises a staging platform 28, wherein the staging platform 28 is secured to the attachment frame 25. The middle standing platform 28 is located above the base 21, and the middle standing platform 28 is parallel to the base 21.

The anchor rod drill carriage comprises two middle anchor rod change mechanisms and two side drill arms 5 which are respectively arranged on two sides of the middle anchor rod change mechanisms.
