The utility model relates to the technical field of ground and mine drilling equipment, in particular to a drill rod adjusting device for ground and mine drilling.

Background

The drill rod is used as a transmission rod piece for connecting surface drilling machine equipment and drilling and grinding equipment at the drilling bottom end in the process of mining, and plays an important role in mining construction. During construction, the number of drill rods is required to be increased along with the increase of the drilling depth. Generally, the drill rods are horizontally arranged on site, and when the drill rod drilling machine is used, the drill rods are firstly conveyed to the vicinity of the drilling machine by means of conveying equipment, and then the drill rods are erected by site workers and then connected to the upper ports of the drill rods arranged in the drilling well. In addition, the drill rods used on site are of various types, not only are the lengths of the drill rods different, but also the arrangement structures in the pipe walls are different, and sensing electric components are locally arranged in part of the pipe walls. In order to reduce the operation intensity of workers and improve the working efficiency of butt joint of drill rods, a device which can automatically grab the drill rods horizontally swing and butt joint the drill rods vertically at the upper ends of the drill rods in a drilling well is urgently required to be designed, and the device is required to be capable of flexibly adapting to drill rods of different lengths and different types.

SUMMERY OF THE UTILITY MODEL

The drill rod adjusting device for the earth and mineral drilling provided by the utility model can grasp and erect the drill rod conveyed to the side of the drilling machine in a construction site, and adjust the position of the lower end of the drill rod to complete the operation of butting and installing the upper end of the uppermost drill rod in a drilled well, and the whole process is time-saving, labor-saving, efficient and convenient.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a drill rod adjusting device for underground mine drilling comprises an assembly base arranged on a vehicle body, a sliding seat matched with the assembly base through a linear rail structure arranged horizontally, a transmission case fixed on the upper portion of the sliding seat, a vertical arm and at least two clamping claw portions arranged on the vertical arm.

The lower portion of the upright arm extends into the gear box so that the gear box can selectively drive the upright arm into a vertical state and a horizontal state.

The right side of each clamping jaw part is arranged in the vertical arm, and the left side of each clamping jaw part extends out of the vertical arm and is provided with a clamping jaw capable of selectively clamping and loosening a drill rod.

And the vertical arm is provided with a driving unit which can respectively control the lifting of each clamping jaw part.

The sliding base can carry the vertical arm to move relatively to the outside of the left side wall of the assembly base.

Specifically, a plurality of fixed blocks arranged at intervals are arranged on the vertical arm, and the fixed blocks correspond to the clamping jaw portions one to one.

The driving unit is a lead screw transmission unit matched with a motor, the motor is installed in a motor groove formed in the fixed block, and the screw rod is matched with the part, placed in the vertical arm, of the clamping jaw portion.

In order to facilitate the installation of the wire lever and the guide rod. Preferably, the vertical arm is provided with guide strips corresponding to the lower parts of the fixed blocks, the guide strips are positioned on the vertical edges of the two sides of the vertical arm, and each pair of guide strips is matched with one sliding block. The slider can slide in the vertical direction relative to the guide bar and can be fixed to the upper portion of the guide bar by means of a bolt. Both ends of the wire lever are respectively disposed in the fixing block and the slider block.

Furthermore, the sliding seat is provided with a balance plate which is opposite to the right side surface of the assembling machine base and extends outwards and horizontally. And a first hydraulic cylinder is mounted on the assembly base, and the rod end of the first hydraulic cylinder can apply pressure to the upper end surface of the balance plate. When the slide carriage carries the upright arm to move relatively to the outside of the left side of the mounting base, the balance plate gradually moves into the mounting base, and gradually, the upper end surface of the balance plate is correspondingly arranged below the cylinder rod of the first hydraulic cylinder. When the rod of the hydraulic cylinder tends to extend, the pressure acting on the balance plate can be gradually increased. By means of the matching effect of the first hydraulic cylinder and the balance plate, the cantilever effect formed when the vertical arm relatively moves out of the left side face of the assembly base can be overcome, and particularly the cantilever effect is more obvious when the clamping jaw grabs a drill rod. The first pneumatic cylinder that sets up plays the effect of the line rail structure of cooperation setting between protection slide and the assembly base with the balance plate, leads to the line rail structure to have the emergence to show when preventing to receive the cantilever effect that is showing to warp, influences life.

After the roller is contacted with the drill rod, if relative sliding occurs between the drill rod and the roller, the shaft matched with the roller can drive the cover plate to rotate, the grating on the annular flange B can relatively indicate the grating to act, and a sensing signal is output.

After the grating sensor is arranged, whether the acting force applied to the drill rod by the clamping jaw is large enough can be judged according to the change of the sensing signal, and the drill rod can be kept in a static state relative to the vertical arm. If the roller has relative rotation action, the drill rod slides relative to the clamping jaw, and the clamping action of the clamping jaw on the drill rod needs to be increased.
