Description

TECHNICAL FIELD

[0001] The present application relates to the field of blasting technology, in particular to a kind of blasting hole charging device. BACKGROUND

[0002] Blasting is a kind of technology that uses explosive to produce compression, loosening, destruction, throwing and killing effect in air, water, soil and rock medium or object to achieve the intended purpose. When explosive charge is exploded in soil and rock medium or structure, it makes soil and rock medium or structure produce compression, deformation, destruction, loosening and throwing phenomenon, which is mainly used in earthwork engineering, and demolition of metal buildings and structures.

[0003] Through blasting technology, the efficiency of construction can be greatly improved. When blasting, it is necessary to drill holes on the working surface, and then send explosive with installed electronic detonator into the blasting hole. However, the existing explosive filling is mostly to directly put explosive into the blasting hole without using charging tool, which may cause hidden trouble due to incorrect position of electronic detonator. In actual construction, explosive needs to be placed in blasting hole at intervals, and at this time, the height control of each explosive hole is extremely important. SUMMARY

[0004] To solve the above problems, the present application discloses a kind of blasting hole charging device, including first clamping plate and second clamping plate, the middle part of first clamping plate and second clamping plate is respectively fixedly connected with first connecting seat, and connecting plate is arranged at first connecting seat, and connecting plate and first connecting seat are rotationally connected. First clamping plate, second clamping plate cooperate with connecting plate to form clamping structure, and explosive is clamped at lower end during use, and then it is sent into blasting hole.

[0005] The upper side wall of the second clamping plate is fixedly connected with the second connecting seat, and the second connecting seat is fixedly connected with the supporting plate. When the device is working, the other end of the supporting plate abuts against the first clamping plate. When clamping explosive, it is placed between the lower parts of the first clamping plate and the second clamping plate in advance, and then the supporting plate is buckled, so that the supporting plate is as horizontal as possible, that is, the upper ends of the first clamping plate and the second clamping plate are stretched, and the lower ends are contracted to clamp the explosive.

[0006] Preferably, the upper end of the connecting plate is threadedly connected with a connecting rod, and the middle part of the supporting plate is provided with a through hole, and the connecting rod passes through the through hole. The connecting rod is convenient for lowering the first clamping plate and the second clamping plate into the interior of the blasting hole. If the hole is deep, different lengths of connecting rods can be replaced, or a lengthening method like a Luoyang shovel can be used.

[0007] Preferably, the upper end of the connecting rod is fixedly connected with a horizontally arranged handle. The handle is arranged to facilitate the gripping of the device, and the horizontal handle avoids the device from falling into the blasting hole.

[0008] Preferably, the lower sidewalls of the first and second clamping plates are provided with clamping grooves, and the clamping grooves are clamped with support arcs.

[0009] Preferably, the support arcs comprise elastic support segments, both ends of the elastic support segments are provided with protruding segments, the protruding segments are fitted in the clamping grooves, and the lower ends of the protruding segments are fixedly connected with inclined support segments. After the explosive is placed on the support segments and sent into the blasting hole, when the first and second clamping plates are loosened, the support segments release elastic potential energy, so that the elastic support segments are expanded, and the end portions of the elastic support segments abut against the inner wall of the blasting hole, thereby playing a role of height retention.

[0010] The beneficial effects of the present application are as follows:

[0011] 1. The first and second clamping plates are provided, and the explosive can be clamped at the lower portion and then safely and stably put into the blasting hole.

[0012] 2. The support arcs are additionally provided on the basis of the first and second clamping plates, and the inclined support segments of the support arcs can ensure that the support arcs are suspended in the interior of the blasting hole after being put in, i.e. the depth of explosive putting can be set, thereby meeting the needs of blasting.
