Description

Technical Field

[0001] This utility model relates to coal mine tunneling equipment, and more particularly to a hydraulic anchor drilling rig mobile platform for an anchor bolt transfer unit. Background Technology

[0002] In the equipment components of rapid tunneling systems in coal mines, bolt transfer units are widely used at the tunneling face. By integrating bolt support, material crushing, and transportation functions, the bolt transfer unit works collaboratively with the integrated tunneling and bolting machine, enabling simultaneous tunneling and support. This resolves the incoordination between support and transportation in traditional operations and significantly shortens the work cycle. The common installation method for the airborne anchor bolt drilling rig used in the anchor bolt transfer unit for roof support is as follows: using a lateral sliding mechanism, multiple airborne hydraulic anchor bolt drilling rigs are arranged. The airborne anchor bolt drilling rigs can move laterally. However, since multiple airborne hydraulic anchor bolt drilling rigs share a single sliding track, they can only support the same row of top anchor cables or anchor bolts. When any one of the airborne hydraulic anchor bolt drilling rigs has not completed its support work, the anchor bolt transfer unit cannot move forward or backward to construct other rows of top anchor cables or anchor bolts. Only after all the drilling rigs have completed their work can the unit move forward one row distance via tracks to carry out the support work for the next row of anchor cables or anchor bolts, which affects the support efficiency of anchor cables or anchor bolts.

[0003] Another approach is to install a hydraulic operating arm equipped with a hydraulic anchor drill on each of the left and right sides of the front of the anchor bolt transfer unit. This gives the onboard hydraulic anchor drill a greater degree of freedom, enabling support operations with different rows of anchor bolts (cables). Each drill can move independently laterally or forward and backward. However, due to limitations imposed by the front receiving hopper, the rear middle transport chute, and the overall frame structure of the anchor bolt transfer unit, the hydraulic operating arms must be raised to a certain height to avoid positional interference between the hydraulic operating arms and the drill (bottom of the operating platform) and other structures. Furthermore, the raised operating platform is higher relative to the roadway floor, reducing the space between it and the roadway roof, making it difficult for personnel to operate from the platform, inconvenient for support operations, and posing higher safety risks to operators. Additionally, the reduced operating space shortens the drill box stroke during support operations, increasing the frequency of drill rod changes and reducing the efficiency of the support operation. Utility Model Content

[0004] The purpose of this utility model is to propose a hydraulic anchor drilling rig mobile platform for anchor bolt transfer unit, which improves the support operation of anchor bolt transfer unit and increases operation efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is: a hydraulic anchor bolt drilling rig mobile platform for an anchor bolt transfer unit, including an anchor bolt transfer unit 10, wherein the anchor bolt transfer unit is equipped with an anchor bolt drilling rig 20, the anchor bolt transfer unit is equipped with a longitudinal moving device 30 and a transverse moving device 40 for the drilling rig, and the longitudinal moving device 30 and the transverse moving device 40 for the drilling rig drive the anchor bolt drilling rig 20 to move.

[0006] Furthermore, the left and right sides of the anchor bolt transfer unit are equipped with a longitudinal moving device 30 and a lateral moving device 40 for the drilling rig.

[0007] Furthermore, in order to achieve two-dimensional movement of the anchor drilling rig 20, the longitudinal moving device 30 of the drilling rig is arranged above the track 11 of the anchor transfer unit, and the lateral moving device 40 of the drilling rig is arranged on the longitudinal moving device 30. The longitudinal moving device 30 drives the lateral moving device 40 of the drilling rig to move along the traveling direction of the track 11 of the anchor transfer unit, and the lateral moving device 40 drives the anchor drilling rig to move perpendicular to the traveling direction of the track 11 of the anchor transfer unit.

[0008] Furthermore, the structure of a drilling rig longitudinal moving device is as follows: the drilling rig longitudinal moving device 30 includes a longitudinal slide block 31 and a longitudinal slide frame 32, the longitudinal slide frame 32 slides on the longitudinal slide block 31, the longitudinal slide frame is provided with a longitudinal moving column 33, and the drilling rig transverse moving device 40 is installed on the longitudinal moving column.

[0009] Furthermore, in order to realize the movement of the longitudinal slide, the longitudinal slide is provided with an I-shaped slide rail 34, the longitudinal slide 32 slides on the I-shaped slide rail 34, and the drilling rig longitudinal moving device is provided with a longitudinal driving cylinder 35 to drive the longitudinal slide to move.

[0010] Furthermore, the structure of a drilling rig lateral movement device is as follows: the drilling rig lateral movement device 40 includes a lateral slide block 41, a lateral slide frame 42, and a lateral slide table 43. The lateral slide frame 42 slides on the lateral slide block 41, the lateral slide table 43 slides on the lateral slide frame 42, and the anchor drilling rig 20 is mounted on the lateral slide table 43.

[0011] Furthermore, in order to realize the movement of the transverse slide 42, the drilling rig transverse moving device 40 is provided with a slide drive cylinder 44, which drives the transverse slide 42 to slide on the transverse slide block 41. The drilling rig transverse moving device is provided with a slide table drive cylinder 45, which drives the transverse slide table 43 to slide on the transverse slide 42.

[0012] Furthermore, in order to achieve the lateral slide movement, the slide drive cylinder 45 drives the lateral slide 43 to move via the stroke-extending chain 46.

[0013] The beneficial effects of this utility model are: by adopting the longitudinal movement device and the lateral movement device of the drilling rig, the longitudinal and lateral movement of the on-board hydraulic anchor bolt drilling rig can be realized, enabling the anchor bolt transfer unit to perform support operations for multiple rows of anchor cables or anchor bolts, significantly improving work efficiency and ensuring work safety.

Detailed Implementation

[0016] Example 1: like Figures 1 to 11 A mobile platform for a hydraulic anchor bolt drilling rig for an anchor bolt transfer unit includes an anchor bolt transfer unit 10, which is equipped with an anchor bolt drilling rig 20.

[0017] The anchor bolt transfer unit 10 is equipped with a longitudinal moving device 30 and a lateral moving device 40 for the drilling rig.

[0018] In this embodiment, the left and right sides of the anchor bolt transfer unit are equipped with a longitudinal moving device 30 and a lateral moving device 40 for the drilling rig. The left and right sides of the anchor bolt transfer unit are relative concepts; in this embodiment, the left and right sides refer to the left and right sides of the track travel direction of the anchor bolt transfer unit.

[0019] Two sets of longitudinal moving devices 30 for the drilling rig, one on the left and one on the right, are positioned above the track 11 of the anchor bolt transfer unit. Each longitudinal moving device 30 includes a longitudinal slide block 31 and a longitudinal slide frame 32. The longitudinal slide block 31 is positioned along the traveling direction of the track 11 of the anchor bolt transfer unit and is equipped with an I-beam rail 34. The longitudinal slide frame 32 has a groove that slides along the I-beam rail 34, allowing it to slide on the rail, i.e., move along the traveling direction of the track 11 of the anchor bolt transfer unit. The longitudinal moving device is equipped with a longitudinal drive cylinder 35, which drives the longitudinal slide frame 32 to move on the longitudinal slide block 31. The longitudinal slide frame is equipped with a longitudinal moving column 33. In this embodiment, the travel distance of the longitudinal slide frame 32 is 1200 mm.

[0020] The drilling rig's lateral movement device 40 is mounted on the longitudinal movement column 33. The drilling rig's lateral movement device 40 includes a lateral slide block 41, a lateral slide frame 42, and a lateral slide table 43.

[0021] The transverse slide 41 is fixed on the longitudinal moving column 33. The transverse slide 41 extends laterally into the inside of the anchor bolt transfer unit. The transverse slide 41 is perpendicular to the longitudinal slide 31. The transverse carriage 42 moves along the transverse slide 41, that is, perpendicular to the travel direction of the anchor bolt transfer unit track.

[0022] The transverse slide 41 is provided with a slide guide hole 41a, and the transverse slide 42 is provided with a slide guide rod 42a. The slide guide hole 41a and the slide guide rod 42a are slidably engaged. The transverse slide 42 is provided with two slide drive cylinders 44, which drive the transverse slide 42 to move.

[0023] A transverse slide 43 slides on a transverse carriage 42, and the anchor drilling rig 20 is mounted on the transverse slide 43. The transverse carriage 42 is provided with a slide guide rod 42b, and the transverse slide 43 is provided with a slide guide hole 43b, which slides in slidable engagement with the slide guide rod 42b. The transverse carriage 42 is provided with a slide drive cylinder 45, which drives the stroke-extending chains 46 on both sides to move. One side of the stroke-extending chain 46 is fixed to the transverse carriage 42 by a chain fixing member 46a, and the other side of the stroke-extending chain 46 is connected to the transverse slide 43. When the slide drive cylinder 45 moves, it drives the stroke-extending chain 46 to move, which in turn drives the transverse slide 43 to slide on the transverse carriage 42. The speed and stroke of the transverse slide 43 are twice that of the slide drive cylinder 45.

[0024] The transverse slide 43 drives the anchor drilling rig 20 to move laterally, and the anchor drilling rig 20 moves along the direction of travel perpendicular to the track of the anchor transfer unit.

[0025] In this embodiment, the drilling rig lateral movement device 40 is mounted on the drilling rig longitudinal movement device 30, and the drilling rig longitudinal movement device 30 drives the drilling rig lateral movement device 40 to move longitudinally. The anchor bolt drilling rig 20 is mounted on the drilling rig lateral movement device 40, and the drilling rig lateral movement device 40 drives the anchor bolt drilling rig 20 to move laterally. This achieves two-dimensional movement of the anchor bolt drilling rig 20 on the anchor bolt transfer unit 10.

[0026] Lateral movement of the anchor drill rig 20, such as Figure 2 The two anchor drilling rigs 20 shown are moved laterally to both sides. Figure 3 The two anchor drilling rigs 20 shown are moved laterally to the middle position, enabling them to perform anchor bolt support operations at multiple locations in a row. The longitudinal movement of the anchor drilling rigs 20 is as follows: Figure 4 The two anchor drilling rigs 20 shown can move longitudinally, and can achieve the support operation of an adjacent row of anchors (cables) of the top anchor without moving the anchor transfer unit, which significantly improves the operation efficiency and has good reliability and safety.
