Problems solved by technology
[0003] In the existing technology, such as mining and blasting in underground mines, the blast hole (10-20 meters long) is drilled in advance, and powdery explosives are blown into the blast hole. The powdered explosives blown in are easily washed away by water, making it difficult to place the explosives, wasting explosives, time-consuming and laborious, and affecting work efficiency
Leakage often occurs in blastholes, which may easily cause insufficient explosive charge density at the bottom of the hole, which will affect the blasting effect, and prone to overhanging or collapsed ore blocks, which will affect production
When powdery explosives are blown in, the amount of reversed powder is large and the waste is serious
The existing charging method cannot realize uncoupled charging and discontinuous charging, cannot effectively exert the power of explosives, and the occurrence of overlapping explosion areas is inevitable, which affects the blasting effect and wastes explosives
It is difficult to control the amount of explosives blown in, and it is a waste of explosives

Embodiment Construction
[0022] see figure 1 -6, the names of parts are as follows: suspension arm 1, wing arm 2, horizontal contact plate 3, shaft pin 4, rope hole 5, center pin shaft 6, delivery rod 7, U-shaped fork 8, and U-shaped clip 9.
[0023] see figure 1 -5, figure 1 For the propped state. An explosive traction supporter is placed in the hole, including a suspension arm 1, and three spaced rope holes 5 are arranged on the suspension arm 1.
[0024] see figure 1 , 3 , 4, 5, the upper end (front end) of the suspension arm 1 is hinged with a pair of wing arms 2, and the two wing arms 2 are cross-engaged and docked, and are hinged with the suspension arm 1 through the central pivot pin 6.
[0025] see figure 2 , the outer ends of the two wing arms 2 are hinged with a horizontal contact plate 3, and the horizontal contact plate 3 is an arc panel. The upper side of the outer end of the wing arm 2 is arc-shaped.
[0026] see figure 1 , 6 , the suspension arm 1 is connected to the del...

The invention relates to an explosion auxiliary tool, in particular to a traction supporting device for installing explosives in a hole. The traction supporting device comprises a suspension arm. The front end of the suspension arm is hinged to at least one pair of wing arms, and the outer end of each wing arm is hinged to a transverse contact plate. The two wing arms are connected with a conveying rod. A rope for conveying the explosives is connected with the suspension arm in a hanged mode. The whole traction supporting device can be conveniently thrown deep into the shot hole in a positioned mode, the wing arms are unfolded, and then the explosives are conveyed through the rope. Positioning is accurate, the explosive charging length can be quantified, and layered explosive loading is realized. Explosive loading is not affected by the geographical conditions in the shot hole, the trouble that leaking water flushes away the explosives is saved, waste of the explosives is avoided, and the explosives are saved. Non-coupled explosive loading and non-continuous explosive loading can be realized, so that the explosion effect is improved, and the explosives are saved. The phenomenon of explosive reversing is avoided.
Description
[0001] technical field [0002] The invention relates to a blasting auxiliary tool, that is, an explosive traction supporter is placed in a hole. Background technique [0003] In the existing technology, such as mining and blasting in underground mines, the blast hole (10-20 meters long) is drilled in advance, and the powdery explosive is blown into the blast hole. The powdered explosives blown in are easily washed away by water, and it is difficult to place the explosives, which wastes the explosives, takes time and effort, and affects work efficiency. Leakage often occurs in blastholes, which may easily cause insufficient explosive charge density at the bottom of the hole, affecting the blasting effect, and prone to overhanging or collapsed ore blocks, which will affect production. When the powdery explosive is blown in, the amount of reversed powder is large and the waste is serious. The existing charging methods cannot realize uncoupled charging and discontinuous chargi...
