Examples

See fig. 1-4:

the utility model provides a device for centering a heavy-duty drill rod with a large caliber, which comprises: a support bracket 10, a connector 20 and an adjustment assembly 30.

In actual use, the support frame 10 is vertically placed on the steel platform for fixing the lower drill rod a, so that the bottom of the support frame 10 is in contact connection with the steel platform, one side of the support frame 10 is connected with the connecting piece 20, and the connecting piece 20 is connected with the lower drill rod a. The adjusting assembly 30 is installed at the top of the supporting frame 10 and abuts against one side of the upper drill rod B, and the adjusting assembly 30 can move in the horizontal direction.

With this arrangement, when the lower drill rod a is docked with the upper drill rod B, a misalignment occurs, simply by connecting the connector 20 with the lower drill rod a, while pushing the upper drill rod B through the adjustment assembly 30. The connector 20 pulls the lower drill rod a during pushing of the upper drill rod B by the adjustment assembly 30 such that the lower drill rod a moves toward the upper drill rod B until the lower drill rod a is fully centered with the upper drill rod B. The adjusting mode is simple and efficient, is easy to operate, reduces the difficulty of centering adjustment of the lower drill rod A and the upper drill rod B, and improves the efficiency of engineering construction.

In actual use, the adjusting assembly 30 is mainly composed of a roller box 31, a roller mounting frame 32, a roller 33 and a driving part.

The bottom of the roller box 31 is fixedly connected with the top of the support frame 10, and one side of the roller box 31 is provided with an opening, and the opening is opposite to one side of the upper drill rod B.

The roller 33 is mounted on the roller mounting frame 32, and both ends of the roller 33 are connected with the roller mounting frame 32 by a shaft.

The roller mounting frame 32 is placed in the roller box 31, one side of the roller mounting frame 32 is connected with a driving part, and the driving part pushes the roller mounting frame 32 to drive the roller 33 to extend out along the opening of the roller box 31, so that the roller box 31 forms a moving and accommodating channel of the roller mounting frame 32. When the roller 33 presses one side of the upper drill rod B, the roller 33 pushes the upper drill rod B to move along the horizontal direction, and transmits the reaction force to the support frame 10, so that the support frame 10 drives the connecting piece 20 to pull the lower drill rod a, and the lower drill rod a and the upper drill rod B move in opposite directions.

For convenience of operation, the driving part is a screw guide 34 in actual use. A mounting hole is provided in one side of the roller housing 31, and an internal thread is provided in the mounting hole. The shaft of the screw guide 34 is provided with external screw threads, and the screw guide 34 and the mounting hole form a screw connection. One end of the screw guide 34 passes through the mounting hole of the roller box 31 and is connected to one side of the roller mounting frame 32.

In actual use, the roller mounting frame 32 can be pushed to move along the inside of the roller box 31 only by rotating the threaded guide rod 34, so that the roller 33 is driven to extend out along the opening of the roller box 31 to extrude the upper drill rod B.

The connector 20 is mainly composed of a semicircular clip 21, an upper sub-clip 22 and a lower sub-clip 23.

One side of the semicircular clamp 21 is fixedly connected with one side of the support frame 10; one ends of the upper sub-clamp 22 and the lower sub-clamp 23 are respectively hinged with two ends of the semicircular clamp 21, and the other ends of the upper sub-clamp 22 and the lower sub-clamp 23 are detachably connected through fastening bolts 25. The upper auxiliary clamp 22, the lower auxiliary clamp 23 and the semicircular clamp 21 jointly encircle a hoop which can be used for connecting the lower drill rod A, and the inner diameter of the hoop is the same as the diameter of the lower drill rod A.

Main pin shafts 24 are arranged at the connection positions of the upper auxiliary clamping hoop 22, the lower auxiliary clamping hoop 23 and the semicircular clamping hoop 21, so that the upper auxiliary clamping hoop 22 and the lower auxiliary clamping hoop 23 are hinged with two ends of the semicircular clamping hoop 21 respectively.

When in actual use, an operator can open or close the hoop formed by surrounding the upper auxiliary hoop 22, the lower auxiliary hoop 23 and the semicircular hoop 21 only by adjusting the fastening bolts 25, so that the lower drill rod A is clamped and fixed, and the whole operation process is simple and convenient.

In addition, in order to ensure the stability and portability of the support frame 10, the support frame 10 is arranged to be spliced or welded into a ladder-shaped support by two vertical long plates and a plurality of horizontal short plates, so that the roller box 31 can be better supported, and the support frame is not easy to deform when being pulled during use, and the use stability of the whole device is improved.

Similarly, in the place with the electric power condition of using, can replace the screw guide 34 with electric putter, it is more laborsaving convenient.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
