Description

Technical Field

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

[0002] Hole plugging is a crucial step in tunnel blasting construction, directly and significantly impacting blasting results. Failure to plug or poor plugging quality will cause blasting gases to escape from the blast holes prematurely, failing to fully utilize their rock-breaking properties and generating large amounts of toxic gases within the tunnel, endangering the health of workers.

[0003] Currently, the sealing materials used in the market are mainly rock powder or yellow mud. These materials require manual shovel operation by workers, which is tedious and increases the workload of workers. Furthermore, it is difficult to control the sealing intensity during the sealing process, and excessive sealing force may cause damage to the lead wire. Summary of the Invention

[0004] The purpose of this invention is to provide a blast hole sealing device to solve the above-mentioned defects caused by the prior art.

[0005] A blast hole sealing device includes a sealing shell, a gripping mechanism on the outer side of the sealing shell for positioning the outer side of the sealing shell and aligning the sealing shell and the blast hole, a sealing tube for penetrating one side of the sealing shell, a rectangular tube for penetrating the top of the sealing tube, and a squeezing mechanism inside the sealing tube for squeezing the mud used for sealing and sealing the detonator used for blasting, thereby improving the blasting effect.

[0006] Preferably, the gripping mechanism includes an outer support frame, a positioning shaft seat, and a handle. The outer support frame is disposed on the outside of the sealing shell, and positioning shaft seats are disposed on the left and right sides of the outer support frame. A handle is connected to the outside of the positioning shaft seat.

[0007] Preferably, the handle is connected to the outer support frame via symmetrically arranged positioning shaft seats.

[0008] Preferably, the extrusion mechanism includes a control shaft, a lead screw, an inner threaded sleeve, an extrusion disc, a guide slider, and an outer rubber sleeve. The lead screw is connected to one side of the control shaft, and a sealing housing is connected through the control shaft. The inner threaded sleeve is connected to the outer side of the lead screw, and the outer rubber sleeve is connected through the outer side of the inner threaded sleeve. The extrusion disc is connected to the top of the inner threaded sleeve, and guide sliders are provided on both the upper and lower sides of the extrusion disc.

[0009] Preferably, the inner end of the sealing pipe fitting is symmetrically provided with sliding grooves.

[0010] Preferably, the sealing pipe is connected to the guide slider through an internal groove.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The rectangular tube is used to position the sealing pipe fitting, which makes it easy to fill the inside of the sealing pipe fitting with sealing mud of different sizes. This allows workers to quickly fill the inside of the equipment with sealing mud, improving the flexibility of the equipment in the process of plugging the inside of the blast hole. The angle of the handle can be adjusted by rotating it on the outside of the positioning shaft seat, allowing for multi-angle adjustment and control of the sealing shell.

[0013] 2. The operator directly holds the control shaft, which drives the lead screw to rotate. By setting lead screws of different lengths, the internal thread sleeve and the extrusion plate are moved laterally, thereby adjusting and controlling the depth of the extrusion plate. This avoids the detonator lead wire from breaking or short-circuiting due to excessive extrusion force, ensuring the flexibility of the detonator during the sealing process.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, a blast hole sealing device includes a sealing shell 1. A gripping mechanism 5 is provided on the outer side of the sealing shell 1. The gripping mechanism 5 positions the outer side of the sealing shell 1, thereby aligning the sealing shell 1 and the blast hole. A sealing tube 6 is connected through one side of the sealing shell 1. A rectangular tube 7 is connected through the top of the sealing tube 6. A squeezing mechanism 9 is provided inside the sealing tube 6. The squeezing mechanism 9 squeezes the mud used for sealing, thereby sealing the detonator used for blasting and improving the blasting effect.

[0023] In this embodiment, the gripping mechanism 5 includes an outer support frame 2, a positioning shaft seat 3, and a handle 4. The outer support frame 2 is disposed on the outside of the sealing housing 1, and the positioning shaft seats 3 are disposed on the left and right sides of the outer support frame 2. The handle 4 is connected to the outside of the positioning shaft seat 3.

[0024] In this embodiment, the handle 4 is connected to the outer support frame 2 through symmetrically arranged positioning shaft seats 3. The positioning shaft seats 3 are used to position the handle 4, which facilitates the storage and unfolding of the device.

[0025] In this embodiment, the extrusion mechanism 9 includes a control shaft 8, a lead screw 10, an inner threaded sleeve 11, an extrusion disc 12, a guide slider 13, and an outer rubber sleeve 15. The lead screw 10 is connected to one side of the control shaft 8, and the sealing housing 1 is connected through the control shaft 8. The inner threaded sleeve 11 is connected to the outside of the lead screw 10, and the outer rubber sleeve 15 is connected through the outside of the inner threaded sleeve 11. The extrusion disc 12 is connected to the top of the inner threaded sleeve 11, and guide sliders 13 are provided on both the upper and lower sides of the extrusion disc 12. The movement range of the device is adjusted by the lead screw 10 to extrude and seal blast holes of different depths.

[0026] In this embodiment, the inner end of the sealing pipe 6 is symmetrically provided with sliding grooves 14, and the extrusion plate 12 is positioned by the symmetrically arranged sliding grooves 14.

[0027] In this embodiment, the sealing pipe 6 is connected to the guide slider 13 through the internal groove 14. The guide slider 13 slides on the outside of the groove 14 to position the extrusion plate 12.

[0028] In practical applications, this blast hole sealing device includes the following tasks:

[0029] Step 1: The operator first holds the handle 4 and rotates it on the outside of the positioning shaft seat 3 to adjust the angle of the handle 4. After the sealing shell 1 is used, the handle 4 can be rotated in the opposite direction on the outside of the positioning shaft seat 3 to make the handle 4 vertical, which is convenient for storing the equipment. The operator pulls the sealing tube 6 through the handle 4 to insert the sealing tube 6 into the inner wall of the rupture hole.

[0030] Step 2: The operator puts the sealing mud column into the rectangular tube 7, and guides the mud column directly into the interior of the sealing fitting 6 through the rectangular tube 7. The operator can hold the handle 4 and drive the screw 10 to rotate through the handle 4, so that the screw 10 drives the inner threaded sleeve 11 to move laterally. The inner threaded sleeve 11 slides on the outside of the slide groove 14 through the guide sliders 13 set on both sides, thereby adjusting the position of the extrusion plate 12.

[0031] Step 3: The extrusion disc 12 pushes the mud column inside the sealing pipe 6. The extrusion disc 12 is discharged from the inside of the sealing pipe 6, so that the mud column is directly introduced into the inside of the explosion hole. The mud column is directly pressed to the explosion position of the detonator. The extrusion disc 12 extrudes and deforms the surface of the mud column, so that the mud column is extruded and sealed from the inside of the explosion hole, thereby extruding and sealing the through hole used for the explosion of the detonator.

[0032] Step 4: The operator rotates the control shaft 8 in the opposite direction, which drives the lead screw 10 to rotate in the opposite direction. This causes the extrusion disc 12 and the inner threaded sleeve 11 to retract into the sealing pipe 6, so that the extrusion disc 12 moves to the other side of the rectangular tube 7, making it easier to fill the interior of the rectangular tube 7 with another set of mud columns. The outer support frame 2 is used to position the outer side of the sealing shell 1 to prevent the sealing pipe 6 from shifting or shaking.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
