Description

Technical Field

[0001] The utility model relates to a multi-purpose device for cleaning and charging mining blasting holes, belonging to the technical field of mining blasting equipment. Background Art

[0002] In underground mining activities, drilling is often required to meet various construction needs. Some boreholes do not have high requirements for the state of the borehole when used, such as some boreholes used for grouting surrounding rocks. In addition, a considerable number of boreholes have high requirements for the state of the borehole, such as when the top needs to be cut to block the high stress transmission and protect the tunnel. Whether blasting or hydraulic fracturing requires drilling, such projects have high requirements for whether the borehole is collapsed, whether there are broken rocks and coal blocks, and whether the hole wall is clearly visible.

[0003] However, since the borehole can be a few meters shallow or hundreds of meters deep, it is difficult for existing equipment to complete the work of cleaning the inside of the borehole, and charging is required after the borehole detection and cleaning is completed. If two sets of equipment are used for charging and borehole cleaning, it will cause a waste of resources. For this reason, the utility model is proposed, which can meet the needs of borehole detection, cleaning and charging at the same time. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a multi-purpose device for cleaning and charging mining blasting boreholes, which can not only detect the quality of the borehole and clean the rock fragments inside the borehole, but also meet the installation requirements of the explosives and effectively prevent the explosives from sliding during the charging process, thereby avoiding the impact of charging failure on the blasting effect.

[0005] The technical solution of the utility model is as follows:

[0006] A multi-purpose device for cleaning and charging blasting drill holes for mining, comprising an extension rod, a detection and cleaning mechanism and a charging mechanism, wherein one end of the extension rod is connected to the detection and cleaning mechanism or the charging mechanism;

[0007] The detection and cleaning mechanism comprises a cleaning rod, a sponge and a brush. One end of the cleaning rod is threadedly connected with an extension rod, and the other end of the cleaning rod is sequentially provided with a sponge and a brush. The charging mechanism comprises a charging rod and a limiter.

[0008] Preferably, the extension rod and the cleaning rod are both hollow tubes, water injection pipes are provided inside the extension rod and the cleaning rod, and a water spray hole is provided on the cleaning rod. When in use, the water injection pipe is connected to high-pressure water for water spray cleaning.

[0009] Preferably, according to the utility model, the sponge is a hollow cylindrical structure with a length of 30 cm and a diameter adjusted according to the diameter of the borehole. Its function is to clean excess moisture from the inner wall of the borehole. A brush is provided on the cleaning rod on the side of the sponge away from the bottom of the hole. The brush is provided on the cleaning rod on the side away from the bottom of the hole. The brush is provided with a water spray hole.

[0010] Preferably, according to the utility model, the limiter includes a limit cylinder, a support plate, a clamping rod, a pull rod, a pull plate, a spring and a partition, wherein one end of the limit cylinder is slidably mounted on the charging rod, a partition is provided at one end of the charging rod located in the limit cylinder, a support plate is fixedly provided at the other end of the limit cylinder, the upper and lower sides of the support plate are hinged with clamping rods respectively, and a movable gap for the clamping rod is left between the upper and lower sides of the support plate and the limit cylinder, the end of the clamping rod located in the limit cylinder is hinged with a pull rod, the other ends of the two pull rods are fixedly connected with a pull plate, and a spring is provided between the pull plate and the partition.

[0011] When in use, a detection and cleaning mechanism is installed on the extension rod, and the detection and cleaning mechanism is inserted into the bottom of the hole. If the insertion length is inconsistent with the designed length of the borehole, it means that the borehole has collapsed, and the device needs to be pulled out. Use the drill to drill again until the insertion length is consistent with the designed length of the borehole, and then insert the water injection pipe into the extension rod and the cleaning rod. The water injection pipe is connected to high-pressure water to spray and wash the hole wall. At the same time, the device is slowly pulled out. During the pulling out process, the cleaning rod is rotated so that the brush cleans the broken rocks on the hole wall, and the sponge absorbs excess water on the hole wall. The water spraying operation and the number of cleaning times can be adjusted according to the actual situation of the drilling until the drilling cleaning is completed;

[0012] Then remove the detection and cleaning mechanism, install the charging mechanism on the extension rod, place the explosive in the middle of the clamping rod of the limiter, and push it to the bottom of the hole. During the pushing process, the extension rod compresses the spring through the partition, driving the pull rod to support one end of the clamping rod outward, and the clamping end of the clamping rod is reversely pressed inward to clamp the explosive to prevent it from slipping during the pushing process. After the explosive reaches the bottom of the hole, the extension rod is pulled outward, and the extension rod pulls the spring through the partition, driving the pull rod to pull one end of the clamping rod inward, and the clamping end of the clamping rod releases the explosive. After the device is completely pulled out, it means that the loading is completed and the next blasting operation can be carried out.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model can not only detect the quality of drilling holes and clean up rock fragments inside the drill holes, but also meet the installation requirements of explosives and effectively prevent the sliding of explosives during the charging process to avoid charging failure affecting the blasting effect.

[0015] 2. The utility model has a simple structure and takes into account the detection and cleaning of the borehole and the installation of explosives. It only needs to replace a small part of the structure at the bottom of the hole to meet the needs, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
