Technical field
The utility model relates to fully-mechanized digging machine safety device technical field, refers in particular to a kind of bauxite tunnel fully-mechanized digging machine and to construct airborne forepoling support device.
Background technology
China's opencut tunnel fully-mechanized digging machine tunneling construction, due to the particularity of bauxite, position rock of meeting head on is soft, and the dangerous situation such as roof fall, wall caving easily occurs, and causes rock to drop, and hinders construction, therefore usually adopts the mode of erection multiple tracks steel pipe to carry out front-probe support.This front-probe support mode is a kind of passive protecting mode, exist supporting area little, protect the shortcomings such as top power is little, work efficiency is low, constrain driving speed.
In addition, when fully-mechanized digging machine operation, a large amount of dust can be produced, cause task environmental quality poor, have very large threat to the healthy of operating personnel.Use the spray equipment that fully-mechanized digging machine carries, only can spray by head, poor effect, is difficult to the object realizing quick depositing dust, dedusting.
Utility model content
For the defect that prior art exists, the utility model provides a kind of bauxite tunnel fully-mechanized digging machine to construct airborne forepoling support device.The potential safety hazard that when it can avoid adopting erection steel pipe supporting, manual work is brought; play the effect of protection operating personnel and fully-mechanized digging machine; simultaneously additional spray equipment; can depositing dust, dedusting fast; play and improve operating environment air quality; the object that protection construction operation personnel are healthy, can improve fully-mechanized digging machine construction drivage efficiency on the whole.
The technical scheme that the utility model adopts is:
A kind of bauxite tunnel fully-mechanized digging machine is constructed airborne forepoling support device, comprise protection top net, drencher head and protective screening adjusting device, described protection top net comprises protection wire side and supports the support frame of whole protection wire side, the front end of described protection top net is laid with more than one drencher head, drencher head is connected with the spray water tank of fully-mechanized digging machine by water pipe, the rear side of described protection top net is laid with protective screening adjusting device, described protective screening adjusting device comprises leveling hydraulic jack, principal arm hydraulic jack and upset hydraulic jack, principal arm hydraulic jack is vertically arranged and its output is supported on the rear end skeleton of protection top net, described leveling hydraulic jack is obliquely installed and its output is supported on the middle part skeleton of protection top net, the output shaft of described upset hydraulic jack is connected to the lower end of principal arm hydraulic jack.
As optimal technical scheme of the present utility model, protection wire side and support frame all adopt steel pipe manufacturing to form, and the diameter of steel tube that support frame adopts is greater than the diameter of steel tube that protection wire side adopts.
As optimal technical scheme of the present utility model, described drencher head is two.
As optimal technical scheme of the present utility model, described protective screening adjusting device is provided with two groups and be arranged in parallel.
The beneficial effects of the utility model are:
1, structure is simple, easy-to-use, and practicality is high, without the need to manual work, can adjust the size of supporting and protection structure, with supporting Multiple Type fully-mechanized digging machine use, can again rectangle, crowned section roadway construction use.
2, have multi-functional, except the effect of front-probe support can be met, for fully-mechanized digging machine provides protection to personnel, machine when roadway construction; protection construction environment can also be played; the effect of efficient depositing dust, dedusting, from overall efficiency, improves driving speed and the efficiency of fully-mechanized digging machine.
Accompanying drawing explanation
