Description

Technical Field

[0001] The utility model relates to the technical field of blasting launch fixing, in particular to a chimney directional blasting launch fixing device. Background Art

[0002] The chimney directional blasting launch fixture is a device specially used in the directional blasting construction of chimneys. Its main function is to fix the detonating cord or other blasting equipment used in the blasting, ensuring that they explode in the predetermined path and sequence, thereby achieving the directional collapse of the chimney. Before the blasting, engineers will reasonably select the blasting points and blasting sequences according to the structural characteristics of the chimney, and install the detonating cord. The detonating cord is connected to the detonation system, which can remotely detonate the explosive. During the blasting process, the fixture ensures that the detonating cord maintains the correct position and tension so that the explosive force can be evenly transmitted when detonated, causing the chimney to collapse in the predetermined direction.

[0003] In the prior art, the detonating cord is generally fixed to the side wall of the chimney by means of a wire clip. However, this fixing method requires multiple manual installations at high places, which not only has low work efficiency but is also not firmly fixed. It is easy to fall off during the blasting process, resulting in the explosion force not being evenly transmitted during detonation, causing the chimney to not collapse or not collapse in the predetermined direction. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a chimney directional blasting launch fixture, which has the advantages of improving construction efficiency and safety, and solves the problems in the above-mentioned background technology.

[0006] Preferably, the clamping mechanism includes a clamping frame, which is fixedly connected to the side wall of the fixed plate, and three guide rods are movably connected in a ring-shaped manner with equal spacing in the inner wall of the clamping frame. The outer end of the guide rod is fixedly connected to a limiting plate, the lower end of the guide rod is fixedly connected to the clamping plate, and a return spring is sleeved on the guide rod.

[0007] Preferably, the right side of the steel lock rope is inserted into the inner wall of the device box and is wrapped into a knot at the tail end, and the left side of the steel lock rope is inserted into the inner wall of the right fixing ring and is wrapped into a knot at the tail end.

[0008] Preferably, the iron hook is inserted into the inner wall of the left fixing ring, and the steel lock rope is connected end to end through a connecting mechanism and a connecting block.

[0009] Preferably, two ends of the clamping frame are fixedly connected to the inner wall of the clamping frame and the side wall of the clamping plate respectively.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The detonating cord is installed in the clamping plate and the clamping plate is squeezed by the reset spring to fix the detonating cord. When the explosion occurs, the detonating cord is offset and the detonating cord squeezes the side clamping plate. After the explosion, the reset spring resets the side clamping plate. The clamping mechanism makes the detonating cord stable and will not deviate during use. The explosive force can be evenly transmitted during detonation, causing the chimney to collapse in a predetermined direction.

[0012] 2. The steel lock rope is lowered from the top of the chimney by a rope. When it is in the appropriate position, the servo motor is started. The servo motor drives the rotating sleeve to rotate through the rotating shaft. The rope is contracted by rotating the sleeve, thereby achieving a tightening effect. The device is installed on the side wall of the chimney simply and quickly through the cooperation between the steel lock rope, the connecting mechanism and the connecting block. There is no need for manual installation multiple times at high places, which improves construction efficiency and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The clamping mechanism 4 comprises a clamping frame 41, which is fixedly connected to the side wall of the fixing plate 3. Three guide rods 42 are movably connected in an annular manner at equal intervals in the inner wall of the clamping frame 41. The outer ends of the guide rods 42 are fixedly connected to the limit plates 44, and the lower ends of the guide rods 42 are fixedly connected to the clamping plates 45. The guide rods 42 are sleeved with reset springs 43. The reset springs 43 are used to squeeze the clamping plates 45 to fix the detonating wire. When the explosion occurs, the detonating wire deflects. At this time, the detonating wire squeezes the side clamping plates 45. After the explosion is completed, the reset springs 43 reset the side clamping plates 45. The clamping mechanism 4 makes the detonating wire stable and will not deflect during use. When detonated, the explosive force can be evenly transmitted, so that the chimney collapses in a predetermined direction.

[0021] The right side of the steel lock rope 2 is inserted into the inner wall of the device box 51 and is wound into a knot at the tail end. The left side of the steel lock rope 2 is inserted into the inner wall of the right fixing ring 7 and is wound into a knot at the tail end.

The clamping frame 41 plays a role of squeezing and fixing when fixed in the device, and plays a role of resetting when the detonating wire deviates.

[0024] Working principle: When the device is working, the detonating wire is installed in the clamping plate 45, and the clamping plate 45 is squeezed by the reset spring 43 to fix the detonating wire. When the explosion occurs, the detonating wire is offset, and the detonating wire squeezes the side clamping plate 45. After the explosion, the reset spring 43 resets the side clamping plate 45. The clamping mechanism 4 makes the detonating wire stable and will not deviate during use. When detonating, the explosive force can be evenly transmitted, so that the chimney collapses in a predetermined direction.

The device is installed on the side wall of the chimney simply and quickly through the cooperation between the steel lock rope 2, the connecting mechanism 5 and the connecting block 6.
