Description
Technical Field
The utility model belongs to the technical field of blast in the pit, a massive device is handled in pit is related to.
Background
Caving ore beyond the maximum size permitted by downhole ore drawing and transport conditions is known as lump, a phenomenon often encountered during ore removal in downhole stopes. And when large blocks appear, secondary crushing is needed, and the large blocks are crushed to qualified block degrees.
At present, for the treatment of large blocks in an underground stope, methods such as manual or wood rod supporting blasting objects to the bottom of the large blocks are mostly adopted, although the methods can solve the problem of some large block treatment, unsafe factors such as the sliding of the large blocks from a blasting pile and the injury of operating personnel exist in the method for manually installing the blasting objects; the method that the wood pole supports the blasting object to the bottom of the big block has the problems of one-time use of the wood pole, serious waste and the like, and the method can not well solve the problem of big block treatment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a massive device is handled in pit to the problem that prior art exists.
Therefore, the utility model adopts the following technical scheme:
the utility model provides a massive device is handled in pit, includes the connecting piece and installs in the explosive support of connecting rod one end, the connecting piece includes to constitute by many connecting rods concatenations, connect through the adapter sleeve between the connecting rod, the explosive support includes the support body, the support body is platelike structure, the both ends of support body are fixed with two support curb plates that are parallel to each other respectively, the L line flexible claw that a mutual correspondence set up is respectively installed in the both ends installation of support curb plate, flexible claw is used for being fixed in the explosive support with the explosive.
Furthermore, the inner wall of the connecting sleeve is provided with internal threads, and the two ends of the connecting rod are provided with threads.
Further, the both ends of support curb plate are equipped with the through-hole, the one end of flexible claw stretches into in the through-hole and can remove in the through-hole, the one end that flexible claw stretches into in the through-hole is equipped with the screw thread and installs the nut that vacant is fixed.
Further, the explosive support is made of metal materials.
The beneficial effects of the utility model reside in that: the explosive bag and the detonating detonator are directly placed at the proper position of the big block, the big block is crushed into qualified block degree under the action of the blasting energy and the impact force, the phenomenon that the big block appears in a stope is effectively solved, the potential safety hazard caused by the fact that an operator enters the bottom of the big block to place blasting materials is avoided, and the safety production of the stope is ensured; the structure is simple, the connecting rod and the blasting bracket can be repeatedly used, only the explosive package and the blasting cap need to be fixed, and the production cost is reduced; the construction is convenient, the volume is small, and the device can be flexibly applied to the channel of the underground stope.

Detailed Description
As shown in fig. 1, a device for treating large blocks underground comprises a connecting piece 1 and an explosive bracket 2 arranged at one end of the connecting rod, wherein the connecting piece 1 is formed by splicing a plurality of connecting rods 101, the connecting rods 101 are connected through a connecting sleeve 102, specifically, the inner wall of the connecting sleeve 102 is provided with an internal thread, the two ends of the connecting rod 102 are provided with threads, namely, the connecting pieces 1 are formed by splicing the plurality of connecting rods 102 through the threads, the connecting pieces 1 with different lengths can be spliced by selecting the specific number of the connecting rods 101 according to the situation when in use, the explosive bracket 2 is made of metal materials and comprises a bracket body 201, the bracket body 201 is in a strip-shaped plate structure, two bracket side plates 202 which are parallel to each other are respectively fixed at the two ends of the bracket side plates 201, L-row telescopic claws 203 which are arranged correspondingly to each other are arranged at the two ends, specifically, through holes 204 are formed in two ends of the bracket side plate 202, one end of each telescopic claw 203 extends into the through hole 204 and can move in the through hole, and a nut 205 which is fixed in a vacant mode is installed at one end, extending into the through hole, of each telescopic claw 203 and is provided with threads.
When the explosive is selected, the explosive amount is controlled by paying attention to control of the specific amount of the explosive within the bearing range of the explosive support 2, so that the explosive support 2 is prevented from being damaged due to the fact that the explosive amount is too large; the nut 205 is loosened to adjust the position of the telescopic claw 203, the blasting detonator and the explosive are placed in the explosive bracket 2, then the blasting detonator and the explosive are clamped by the telescopic claw 203, and the nut 205 is tightened to fix the blasting detonator and the explosive.
Then according to the specific position of the big block under the well, the connecting piece 1 is installed, the connecting rod 101 is spliced into a corresponding length through the connecting sleeve 102, and finally, the worker places the explosive bracket 2 at the big block to be blasted through the connecting sleeve 1 to finish the operation of the big block blasting under the well. If the large block is large in size and needs more explosive amount once, a mode of fractional blasting can be adopted, and the explosive support 2 is prevented from being exploded and damaged due to excessive explosive amount once, so that the explosive support cannot be reused.
