Description

Technical Field

[0001] This utility model relates to the field of mining blasting technology, and in particular to a mining blasting auxiliary directional device. Background Technology

[0002] Mining blasting is a rock-breaking method that uses explosives to generate high-pressure gas in rocks or ore bodies, causing them to fracture, loosen, and move. The purpose of mining blasting is to change the shape and position of rocks or ore bodies to meet engineering requirements, thereby improving mining efficiency and quality. The key to mining blasting is how to control the blasting direction and range so as to accurately destroy the target area while avoiding unnecessary damage to the surrounding area. Therefore, auxiliary directional devices are needed in the mining blasting process.

Each bidirectional screw has two sliding blocks threadedly connected to its outer surface. Each sliding block has a guide rod movably hinged inside it. The end of each set of guide rods far from the sliding block is movably hinged to a movable frame. This invention, by rotating the bidirectional screws in conjunction with the limiting blocks, sliding blocks, guide rods, and movable frames, can move the two clamping plates closer together or further apart, thereby enabling the clamping and auxiliary positioning of blasting pipes of different specifications. This ensures the smoothness of the auxiliary orientation device while facilitating the insertion of blasting pipes of different specifications into the pre-drilled holes.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-3 This utility model provides an embodiment of a mine blasting auxiliary directional device, comprising a fixed pipe 1, wherein each adjacent side of the fixed pipe 1 is provided with a preset installation groove 2, each preset installation groove 2 is fixedly connected with a fixed groove 3, each adjacent side of the fixed groove 3 is fixedly connected with a fixed plate 4, each fixed groove 3 is fixedly connected with a plurality of sliding sleeves 5, each sliding sleeve 5 is provided with a clamping spring 6, each adjacent end of the clamping spring 6 is provided with a clamping rod 7, each clamping rod 7 passes through the fixed plate 4 and is slidably connected to the fixed plate 4, and each adjacent end of the clamping rod 7 is fixedly connected with a clamping inner ring 8.

[0031] The fixed tube 1 is the main structural component of the entire device. During blasting operations, the fixed tube 1 can fix the position and direction of the blast, so that the blasting tube can blast at a preset angle and direction, thereby achieving the purpose of directional blasting. A pair of clamping inner rings 8 set inside the fixed tube 1 can fix and hold the blasting tube. The clamping inner rings 8 can clamp and fix blasting tubes of different specifications under the push of the clamping spring 6 and the clamping rod 7, so as to prevent the blasting effect from being affected by the movement of the blasting tube in the fixed tube 1, thereby improving blasting efficiency and safety.

[0032] Multiple sets of limiting rods 9 are fixedly connected to the distal side of the clamping inner ring 8. The distal ends of the limiting rods 9 are slidably connected to the adjacent side of the fixing plate 4. The outer surface of the limiting rods 9 is fixedly connected to the connecting plate 10. The middle part of the connecting plate 10 is fixedly connected to the outer surface of the clamping rod 7. The function of the limiting rods 9 is to control the extension and retraction length of the clamping rod 7 through the limiting rods 9 and the connecting plate 10, thereby adjusting the diameter of the clamping inner ring 8 to adapt to different specifications of explosive charges, and preventing the clamping rod 7 from being misaligned due to misalignment of the clamping inner ring 8.

[0033] The upper end of the connecting plate 10 is slidably connected to an operating rod 11, and the adjacent ends of the operating rod 11 are fixedly connected to a fixing pull ring 12. The middle outer surface of the operating rod 11 is slidably connected to a fixing block 13, and the lower side of the fixing block 13 is fixedly connected to the upper side of the fixing groove 3. The operating rod 11 and the fixing pull ring 12 drive the limiting rod 9 and the connecting plate 10 to move in opposite directions, thereby realizing the retraction of the clamping rod 7, thereby controlling the opening and closing of the clamping inner ring 8, which is convenient for loading blasting cylinders of different specifications. At the same time, the fixing block 13 ensures the movement stability of the operating rod 11.

[0034] A retaining ring 14 is fixedly connected to the outer surface of the operating lever 11 on the opposite side. A return spring 15 is provided on the outer surface of the retaining ring 12 between the fixing block 13 and the connecting plate 10. The retaining ring 14 limits the maximum sliding range of the operating lever 11 to prevent the operating lever 11 from falling out of the fixing block 13. The elastic force of the return spring 15 can restore the operating lever 11 to the initial position after the inner ring 8 of the control clamp is opened and closed, so as to facilitate the next operation.

[0035] Each distal end of the operating lever 11 is provided with a preset pull ring hole 16, and an operating pull ring 17 is slidably connected to the inner surface of the preset pull ring hole 16. The operating pull ring 17 allows for convenient manipulation of the sliding of the operating lever 11, thereby controlling the opening and closing of the clamping inner ring 8. The operating pull ring 17 can be used in conjunction with other external devices such as pull ring hooks to improve the comfort of operation. The angle of the operating pull ring 17 can be adjusted through the preset pull ring hole 16 to adapt to different operating angles and directions.

[0036] Anti-slip layers 18 are fixedly connected to adjacent sides of the clamping inner ring 8, and multiple sets of anti-slip ridges 19 are fixedly connected to adjacent sides of the anti-slip layers 18. The anti-slip layers 18 and anti-slip ridges 19 can increase the friction between the clamping inner ring 8 and the explosive cartridge, preventing the explosive cartridge from sliding or falling off during the blasting process and affecting the blasting effect. By adjusting the material and thickness of the anti-slip layers 18, as well as the shape and density of the anti-slip ridges 19, the friction coefficient of the clamping inner ring 8 can be adjusted to adapt to different explosive charge materials and surface conditions.

[0037] An external fixing ring 20 is fixedly connected to the upper outer surface of the fixed tube 1. The external fixing ring 20 is provided with multiple sets of fixing holes 21. The external fixing ring 20 and the fixing holes 21 can be used with fixing devices such as fixing bolts to fix the entire device in the preset position of the blast hole, so that the device can be firmly fixed inside the blast hole, and the blasting tube can be blasted at a preset angle and direction, thereby achieving the purpose of directional blasting.

[0038] The lower outer surface of the fixed tube 1 is provided with multiple sets of preset slots 22. Each preset slot 22 is slidably connected to a claw 23. A bottom conical cover 24 is fixedly connected to the lower side of the claw 23. The function of this device is to fix the bottom conical cover 24 to the fixed tube 1 by cooperating with the claw 23 and the preset slots 22, so that the device can be more easily and accurately inserted into the borehole, thereby improving the installation efficiency of the device. Since the bottom conical cover 24 is a disposable part, a new bottom conical cover 24 can be quickly and conveniently installed through the preset slots 22.

[0039] Working principle: When using the device, first connect the bottom conical cover 24 to the lower part of the fixed tube 1. The function of the bottom conical cover 24 is to help the device smoothly enter the blast hole and protect the lower part of the fixed tube 1 from wear from the blast hole. The bottom conical cover 24 is a disposable part and needs to be replaced after each blast. A new bottom conical cover 24 can be quickly and easily installed by the cooperation of the claw 23 and the preset slot 22. Then, connect the device to the fixing device such as the fixing bolt through the external fixing ring 20 and the fixing mounting hole 21 to fix the device in the preset position of the blast hole, so that the fixed tube 1 is aligned with the blast hole.

[0040] By pulling the operating ring 17 outward, the operating rod 11 slides outward, simultaneously moving the fixed ring 12, connecting plate 10, limiting rod 9, and clamping rod 7 outward, thereby opening the clamping inner ring 8 outward to provide installation space for the blasting cylinder. The anti-slip layer 18 and anti-slip ridges 19 of the clamping inner ring 8 increase the friction with the blasting cylinder, preventing the blasting cylinder from sliding or falling off. The sliding range of the operating rod 11 is limited by the fixed retaining ring 14, and the movement stability of the operating rod 11 is ensured by the fixed block 13 and the fixed groove 3.

[0041] The blasting cylinder is then inserted into the fixed tube 1 and the inner clamping ring 8. At this time, the inner clamping ring 8 is in the open state, the clamping rod 7 is in the retracted state, the operating rod 11 is at its farthest end, and the return spring 15 is in the compressed state. After the blasting cylinder is completely inserted into the inner clamping ring 8, the operating pull ring 17 is released. At this time, the elastic force of the return spring 15 causes the operating rod 11 to return to its initial position. The clamping rod 7, under the push of the clamping spring 6, pushes the inner clamping ring 8 to clamp the blasting cylinder. The inner clamping ring 8 remains in the clamping state, completing the installation of the device.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
