Description

Technical Field

[0001] The invention relates to the technical field of hole collapse processing equipment, in particular to a device for processing hole collapse in a tunnel blasting blast hole. Background Art

[0002] Usually, when encountering hard rock during mining, it is necessary to crush the rock by blasting. Rock blasting usually requires dozens or even hundreds of blastholes to be charged and blasted simultaneously. Therefore, a long time interval is required from drilling the blastholes to the formation of all the blastholes and the final charging and blasting. However, when drilling blastholes in areas with poor geological environments such as high-altitude stress areas, rock-fragmented areas, and rock-weathering areas, the blastholes formed earlier are prone to collapse and blockage, making it difficult to charge the blastholes smoothly. As a result, a large number of already formed blastholes have become waste holes.

[0003] In the existing technology, there are currently two methods for dealing with the blockage of collapsed blastholes. One is to re-drill and then re-charge; the other is to use a drill, which includes a drill rod, a drill bit, a power part and a power supply. When dealing with collapsed holes, the drill bit is inserted from the blasthole mouth to the bottom of the hole 2-3 times to crush the blocked rock, and the blasthole can be unblocked and then charged.

[0004] However, when re-drilling is used to deal with the collapsed hole, it is time-consuming and detrimental to work progress. When a drill is used for treatment, the gravel in the collapsed hole is only ground and crushed, but the crushed gravel still exists in the collapsed hole, so the staff need to use special tools to get the gravel out, which is inconvenient. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a device for processing collapsed holes in blasting holes in shafts and tunnels.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A device for processing collapsed holes in tunnel blasting, comprising:

[0008] A placement groove is provided on a side wall of the drill bit of the drill;

[0009] The cleaning plate is perpendicular to the axis of the drill bit and rotatably arranged in the placement groove;

[0010] The rotation drive mechanism is arranged on the side wall of the drill rod of the drill, and the power output end is connected to the cleaning plate, which can make the cleaning plate rotate in the placement groove during operation;

[0011] After the drill has finished drilling, the driving mechanism is rotated to rotate one end of the cleaning plate out of the placement slot. When the drill bit is taken out of the drilling hole, the cleaning plate carries out the crushed gravel.

[0012] The rotation drive mechanism comprises:

[0013] A positioning ring, provided on the drill pipe;

[0014] A rotating sleeve is rotatably arranged on the positioning ring, and the rotating sleeve is arranged parallel to the axis of the drill pipe;

[0015] The rotation groove is provided on the side wall of the drill bit and is communicated with the placement groove;

[0016] The support rod is arranged parallel to the axis of the drill rod and is arranged in the rotating groove. One end of the support rod is connected to the rotating sleeve, and the other end is connected to the cleaning plate. The support rod is then connected to the side wall of the placement groove through a damping bearing.

[0017] The rear end and top of the drill are respectively provided with a handle and a second grip.

[0018] The present invention also includes a drill positioning mechanism, which is arranged on the outer wall of the drill and is used to fix the drill on the working surface during drilling to prevent the drill from being displaced during operation and affecting the operation of the drill bit.

[0019] The drill positioning mechanism comprises:

[0020] A micro motor is provided on a side wall of the drill;

[0021] The gear is arranged on one side of the micro motor and is mounted on the side wall of the drill through a rotating shaft;

[0022] The chain belt has one end mounted on the output shaft of the micro motor and the other end mounted on the gear;

[0023] Two positioning plates are vertically arranged on the upper and lower sides of the micro motor and fixedly mounted on the chain belt;

[0024] Two vertical plates are respectively arranged vertically on the two positioning plates;

[0025] Two movable grooves are respectively arranged on the upper and lower side walls of the drill along the axial direction of the drill;

[0026] Two slide plates are slidably arranged in the two movable grooves respectively;

[0027] Two cross bars are respectively arranged on the upper and lower sides of the drill, one end of which is connected to the top of the two vertical plates respectively, and the other end is connected to the two slide plates respectively;

[0028] The two brackets are respectively arranged on the upper and lower sides of the drill, the rear ends of the brackets are respectively connected with the two slides, and the front ends are respectively provided with cones.

[0029] The micro motor is mounted on the side wall of the drill through a motor bracket.

[0030] The positioning plate is fixed to the chain belt via a fixing plate, wherein the fixing plate is arranged on a side wall of the chain belt.

[0031] A guide column is provided in each of the two movable grooves. One end of the guide column is connected to the inner wall of the movable groove, and the other end is connected to a nut through a thread provided at the end thereof. The guide column is slidably connected to a slide plate.

[0032] The beneficial effect of the present invention is that when the blasthole needs to be collapsed, the drill can be started and the drill rod provided at one end of the drill can be extended into the collapsed hole, and the drill bit provided at one end of the drill rod can be used to crush the gravel. After the crushing is completed, the support rod is rotated to make the cleaning plate provided at one end of the support rod rotate out of the placement slot. When the drill bit is withdrawn from the collapsed hole, the crushed gravel can be carried out by the cleaning plate, and then the filling of medicine can be carried out normally, which is more convenient. This avoids the traditional method of re-drilling to deal with the collapsed hole, which is more time-consuming and not conducive to work progress. When the drill is used for treatment, only the gravel in the collapsed hole is ground and crushed, but the crushed gravel still exists in the collapsed hole, and the staff needs to use special tools to get the gravel out, which is more inconvenient. As a preferred technical solution, when the drill positioning mechanism is used, when it is necessary to crush the collapsed hole with the drill bit, the micro motor is first started to rotate the gear. The drill provides power to the micro motor. When the gear rotates, the chain belt rotates, so that the slide slides on the guide post, and then pushes the bracket to move. The cone provided at one end of the bracket can be inserted into the ground to fix it, preventing the drill from shifting during operation. The surface of the guide post is screwed with a nut. When the slide needs to be removed, the nut can be rotated to disengage the nut from the guide post, and the slide can be removed along the guide post. As a preferred technical solution, when the rotary drive mechanism is used, after the drill bit at one end of the drill is crushed, the rotating sleeve can be rotated to rotate the support rod in conjunction with the damping bearing, so that the cleaning plate provided on the surface of the support rod can be rotated out of the placement slot. Then, when the drill rod is removed from the collapsed hole, the cleaning plate can be used to scrape the crushed gravel out of the collapsed hole, which is more convenient. The damping bearing can prevent the support rod from rotating arbitrarily and play a certain limiting role. BRIEF DESCRIPTION OF THE DRAWINGS
