Problems solved by technology

However, since the common operation method of the dry hole spacer is to turn on the deflation switch on the surface, and then put the spacer into the blast hole, the disadvantage of this operation method is that if the operator pauses for a while, the spacer is easy to get stuck It is inside the blast hole and cannot reach the predetermined position, so it is necessary to puncture the spacer, then lift out the damaged spacer, and then re-place a spacer, which not only delays the construction on site, but also wastes the spacer

Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing:

[0009] Such as figure 1 , figure 2 , as shown, the present invention relates to a delivery spacer spacer, 1 woven bag, 2 composite bags, 3 gas storage tanks, 4 deflation switches and 5 switch ropes, characterized in that the delivery type spacer is equipped with Switch cord 5 is on the air release switch 4, and the air release switch 4 is pressed on the air storage tank 3, and the air storage tank 3 is placed in the composite bag 2, and the composite bag 2 is contained in the woven bag 1 inside. When using, pull the switch rope 5, lower the spacer to the predetermined position, then step on the switch rope 5 with your feet, then pull the switch rope 5 with your hands to lift the spacer about two meters, and then send off the switch rope 5 by hand , at this time, the spacer generates a downward movement force, and since one end of the switch rope 5 is stepped on by the fo...

Abstract

The invention provides a delivery type spacer. The delivery type spacer is provided with a woven bag, a composite bag, a gas storage tank, a gas releasing switch and a switch rope and is characterizedin that a pull switch is provided with a base arranged at a tank opening, and a pull rod arranged on the base; toothed structures which are mutually matched are arranged on the pull rod and the base,and the pull switch does not easily open due to the tight biting of the toothed structures in a transportation process and can be pulled open by force in a using process; and meanwhile the toothed structures can prevent the pull rod from returning to an original position. The delivery type spacer solves the problem that when a traditional common spacer is used, firstly the gas releasing switch isopened on the ground surface, and then is put in a blast hole, and if the speed of putting the gas releasing switch is slightly low, the gas releasing switch is blocked in the blast hole due to the excessive expansion speed of the spacer.

Description

technical field [0001] The invention relates to a spacer, in particular to a drop-in spacer. Background technique [0002] In recent years, spacers have been widely used in large mines all over the world due to their simplicity, practicality and low cost, especially the amount of dry holes is far ahead. However, since the common operation method of the dry hole spacer is to turn on the deflation switch on the surface, and then put the spacer into the blast hole, the disadvantage of this operation method is that if the operator pauses for a while, the spacer is easy to get stuck In the blast hole but not reaching the predetermined position, the spacer needs to be punctured, the damaged spacer is brought out, and then a spacer is re-placed, which not only delays the construction on site, but also wastes the spacer. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art a...
