Description

Technical Field

[0001] This utility model relates to the field of deep hole blasting technology, specifically a deep hole blasting sealing device. Background Technology

[0002] Deep-hole blasting in underground engineering is a columnar charge blasting method conducted deep within solid coal and rock formations to enhance the development of internal fractures. Generally, the length of the explosive charge in deep-hole blasting boreholes exceeds 10 meters, and the sealing length of the borehole must be no less than 5 meters. Currently, the commonly used sealing method on-site is mud sealing. However, current field operations have revealed that due to the long charge length and large charge volume, the explosion generates a significant axial impact force, causing the mud sealing material to easily fail and eject, resulting in blowouts. This affects the blasting effect and poses significant safety hazards in high-gas, dust, and other explosive environments.

[0003] In response, Chinese patent application publication number CN212458150U discloses a deep-hole blasting sealing device and structure, belonging to the field of deep-hole blasting technology. Currently, deep-hole blasting sealing often uses yellow mud. Field construction has revealed that due to the long charge length and large charge volume in deep-hole blasting, the explosion generates a large axial impact force, causing the sealing materials such as yellow mud to easily fail and spray out, resulting in blowouts in the explosive, affecting the blasting effect and posing safety hazards. Existing sealing agents are loose and difficult to coagulate, making it difficult to deliver to a fixed position in the deep hole. Even after delivery, they do not fully contact water to expand and solidify, resulting in unstable sealing effects. This invention encapsulates the sealing agent in a container bag, which can be soaked in water to wet the surface. After a targeted rupture, the internal sealing agent has more opportunities to fully contact water, resulting in more complete expansion and solidification, and higher strength.

[0004] However, existing deep-hole blasting sealing devices require the sealing slurry to be delivered into the blast hole during operation, but these devices cannot quickly deliver the sealing slurry into the blast hole as needed, thus affecting work efficiency.

[0005] Therefore, in order to solve the above problems, a deep-hole blasting sealing device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a deep hole blasting sealing device to solve the problem mentioned in the background art of the prior art that the existing deep hole blasting sealing device needs to transport the sealing slurry into the blast hole during use, but the existing device cannot quickly transport the sealing slurry into the blast hole that needs to be sealed as needed, thus affecting the work efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a deep-hole blasting sealing device, comprising: a tube body and a rubber plug, wherein the tube body is provided with a rubber plug, a limiting mechanism is provided at the upper end of the tube body, a fixed sleeve is provided inside the limiting mechanism, a slurry inlet pipe is provided at the upper end of the fixed sleeve, and a slurry return pipe is provided on one side of the fixed sleeve, and a special bearing is provided on the tube body, a movable sleeve is provided on the special bearing, connecting rods are provided on both sides of the movable sleeve, a turntable is provided on the connecting rod, a threaded rod is provided on one side of the turntable, a stop block is provided at one end of the threaded rod, a sealing mechanism is provided at the bottom end of the rubber plug, a limiting sleeve is provided inside the sealing mechanism, a fixed plate is provided at the bottom end of the limiting sleeve, and movable components are provided on both sides of the fixed plate.

[0008] Preferably, a liquid outlet tube is movably mounted on the movable component, and a plug is fixedly mounted on the bottom end of the insertion tube body, with a limiting groove formed on one side of the bottom end of the insertion tube body.

[0009] Preferably, a limiting component is movably installed in the limiting groove, and a support rod is movably installed on the limiting component.

[0010] Preferably, one end of the support rod is movably mounted with a through rod, and one end of the through rod is movably mounted on the liquid outlet pipe.

[0011] Preferably, the fixing sleeve is fixedly installed on the upper end of the insertion tube body, one end of the slurry inlet pipe is fixedly installed on the upper end of the fixing sleeve, one end of the slurry return pipe is fixedly installed on one side of the fixing sleeve, the special bearing is movably installed on the insertion tube body, and the movable sleeve is movably installed on the special bearing.

[0012] Preferably, one end of the connecting rod is fixedly mounted on the movable sleeve, the turntable is rotatably mounted on the threaded rod, one end of the threaded rod passes through the connecting rod, and the abutment is fixedly mounted on the bottom end of the threaded rod.

[0013] Preferably, the limiting sleeve is fixedly installed on the insertion tube body, the fixing plate is fixedly installed on the limiting sleeve, and the movable component is movably installed on both sides of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting a limiting mechanism, the insertion tube body can be limited and supported. The sealing slurry is delivered to the insertion tube body through the slurry inlet pipe inside the mechanism. When the connecting rod is pressed down, the insertion tube body is retracted through the movable sleeve and special bearing, so that the insertion tube body can be inserted into the blast hole. When it reaches the designated position, the turntable drives the threaded rod to rotate. The abutment at one end of the threaded rod supports the wall, thereby supporting the insertion tube body and improving the practicality of the device.

[0016] 2. The device is equipped with a sealing mechanism to seal the blast hole. The insertion tube moves downwards, and the limiting component in the limiting groove drives the support rod. The support rod then moves the outlet pipe via a through rod, causing one side of the outlet pipe to fit against the inner wall of the blast hole. The slurry is then delivered to the blast hole through the outlet nozzle on the outlet pipe, thus sealing the blast hole. A rubber stopper can be used to seal the upper end of the blast hole. Excess slurry is then recovered through the return pipe, thereby improving the device's operating efficiency. Attached Figure Description
