Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] Such as Figure 1~Figure 3 As shown, a repetitive dry ice fracturing rock breaking orifice clamping device includes a clamping device body 2, and the clamping device body 2 includes a half-threaded column 7 with threads in the upper half.

[0038] The top end of the half-threaded column 7 is provided with an upper terminal 1 , and an annular groove 3 is provided on the side wall of the upper terminal 1 . The upper end 1 plays the role of limiting the sleeve 4, preventing the sleeve 4 from unscrewing the half-threaded column 7, and the upper end 1 can also play the role of fixing the half-threaded column 7. When the turntable 6 is rotated, the half-threaded column is avoided. 7 rotates thereupon. The annular groove 3 is used for binding the wire rope 105 .

[0039] The bottom end of the half threaded column 7 is provided with a lower movable end 10, which is a...

Abstract

The invention discloses a repeated dry ice cracking rock breaking orifice clamping device. The repeated dry ice cracking rock breaking orifice clamping device comprises a clamping device body (2), wherein the clamping device body (2) comprises a semi-threaded column (7) with threads on the upper half section; an upper end head (1) is arranged at the top end of the semi-threaded column (7), and anannular groove (3) is formed in the side wall of the upper end head (1); a lower movable end head (10) is arranged at the bottom end of the semi-threaded column (7); the lower movable end head (10) isa box body with an opening in the top end; the opening in the top end of the lower movable end head (10) is fixedly connected with the lower surface of a limiting disc (15); and the semi-threaded column (7) penetrates through the limiting disc (15) and then is movably connected to the interior of the lower movable end head (10). The invention further discloses a using method of the repeated dry ice cracking rock breaking orifice clamping device. According to the repeated dry ice cracking rock breaking orifice clamping device and the using method thereof, the punching phenomenon can be effectively reduced, and the operation safety is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering blasting, and in particular relates to a repetitive dry ice fracturing rock breaking orifice clamping device and a use method thereof. Background technique [0002] Dry ice cracking tube blasting is a new type of blasting method. First, the dry ice is heated and melted to a liquid state through the heating rod system, and then the rapid heating of the internal chemical causes CO 2 The phase transition makes CO 2 The sharp increase in volume breaks through the steel pipe (that is, the wall of the dry ice cracking cylinder) to trigger an explosion, achieving the purpose of blasting. [0003] During the blasting process of the dry ice blasting cylinder, punching incidents may occur due to factors such as bad weather or insufficient sealing materials. The flying of the punching materials and steel pipes will hurt the workers and buildings on the construction site, resulting in the loss of people ...
