Description

Technical Field

[0001] The utility model relates to the technical field of engineering blasting, in particular to a hole expanding and anchoring device for blast holes. Background Technique

[0002] Engineering blasting is widely used in many fields such as mine exploitation, tunnel excavation, road construction, building demolition, etc. In these projects, it is necessary to break rocks, demolish buildings, etc. through blasting. For blasting under complex geological conditions, it is difficult for traditional blast holes with a unified aperture to accurately adjust blasting parameters according to different geological conditions. Therefore, it is necessary to expand the blast holes.

[0003] When expanding the blast holes, it is necessary to expand on the basis of the original blast holes. Therefore, it is necessary to anchor the hole expanding equipment. The existing anchoring equipment is generally installed outside the blast holes and calibrated through the blast holes. This makes the calibration not only more cumbersome, but also the calibrated results are prone to deviation. For this reason, it is necessary to propose a hole expanding and anchoring device for blast holes. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hole expanding and anchoring device for blast holes to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hole expanding and anchoring device for blast holes, including a fixed sleeve. Four moving holes are penetrated through the fixed sleeve. A limiting groove is opened in the moving hole. A clamping block is slidably connected in the moving hole. A limiting block is slidably connected in the limiting groove. The limiting block is fixedly connected to the clamping block. An elastic rubber block is fixedly installed in the limiting groove. The inside of the fixed sleeve is provided with threads and is threadedly connected with a threaded rod. One end of the threaded rod is fixedly connected with a conical pushing block. The other end of the threaded rod extends outside the fixed sleeve and is rotationally connected with a positioning disc through a rotating shaft.

[0006] Preferably, a rotating handle is fixedly connected to the outer wall of the end of the threaded rod located outside the fixed sleeve.

[0007] Preferably, the positioning disc, the threaded rod and the fixed sleeve are all arranged vertically.

[0008] Preferably, the conical pushing block abuts against one end of the four clamping blocks located inside the fixed sleeve.

[0009] Preferably, the elastic rubber block abuts against the limiting block.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: during use, first insert the fixed sleeve into the original blast hole, then rotate the threaded rod to drive the conical pushing block, and the conical pushing block will push the clamping block to move outside the fixed sleeve and abut against the inner wall of the blast hole, thereby clamping and fixing the fixed sleeve and the threaded rod in the blast hole. At this time, the drilling cylinder of the hole expanding device can be sleeved on the positioning disk, and the hole expanding device is supported by the positioning disk, so that the hole expanding device can perform hole expanding operations based on the original blast hole, and the overall operation is simple and convenient.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figures 1 - 4 shown, the present utility model provides the following technical solutions:

[0018] Embodiment 1: A blast hole hole expanding and anchoring device, including a fixed sleeve 1, four moving holes 2 are penetrated through the fixed sleeve 1, a limiting groove 3 is opened in the moving hole 2, a clamping block 4 is slidably connected in the moving hole 2, a limiting block 5 is slidably connected in the limiting groove 3, the limiting block 5 is fixedly connected to the clamping block 4, an elastic rubber block 6 is fixedly installed in the limiting groove 3, the inside of the fixed sleeve 1 is provided with threads and is threadedly connected with a threaded rod 7, one end of the threaded rod 7 is fixedly connected with a conical pushing block 8, and the other end of the threaded rod 7 extends outside the fixed sleeve 1 and is rotatably connected with a positioning disk 9 through a rotating shaft;

[0019] During use, first insert the fixed sleeve 1 into the original blast hole, and then the threaded rod 7 can be rotated. The threaded rod 7 moves within the fixed sleeve 1 and synchronously drives the conical pushing block 8 to move. The conical pushing block 8 abuts against the clamping block 4 through its conical surface, causing the clamping block 4 to be pushed outward and abut against the inner wall of the blast hole, so that the fixed sleeve 1 and the threaded rod 7 are clamped and fixed in the blast hole. The threaded rod 7 supports the positioning disk 9, enabling it to rotate in place. After that, the drilling cylinder of the hole expanding device can be sleeved on the positioning disk, so that the drilling cylinder is parallel to the original blast hole and drills holes with the support of the positioning disk 9, thus completing the hole expanding operation of the blast hole, and the overall operation is simple and convenient.

[0020] Embodiment 2: The technical solutions of this embodiment different from those of Embodiment 1 include:

[0021] Among them, a rotating handle 10 is fixedly connected to the outer wall of one end of the threaded rod 7 located outside the fixed sleeve 1, and the threaded rod 7 can be rotated by rotating the rotating handle 10, making the rotation of the threaded rod 7 more convenient.

[0022] Among them, the positioning disk 9, the threaded rod 7 and the fixed sleeve 1 are all arranged vertically. The fixed sleeve 1 and the threaded rod 7 are placed in the blast hole and support the positioning disk 9, and the positioning disk supports the drilling cylinder, so that the drilling cylinder is parallel to the blast hole.

[0023] Among them, the conical pushing block 8 abuts against one end of the four clamping blocks 4 located inside the fixed sleeve 1, so that the conical pushing block 8 will push the clamping block 4, causing the clamping block 4 to move outward and abut against the inner wall of the blast hole.

[0024] Among them, the elastic rubber block 6 abuts against the limiting block 5. The elastic rubber block 6 will push the limiting block 5, and the limiting block 5 will drive the clamping block 4, so that the clamping block 4 will remain inside the fixed sleeve 1 when the device is not in use.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
