Description
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 construction driver's cabin safety device.
Background technology
Bauxite has the features such as rock stratum is relatively soft, globality is bad, when utilizing fully-mechanized digging machine to carry out tunnelling construction, the dangerous situation such as wall caving, roof fall easily occurs, and fully-mechanized digging machine construction driver is faced with very serious security threat.
At present, when bauxite tunnel fully-mechanized digging machine tunneling construction, owing to considering the operation line-of-sight problems of driver, driver's cabin is open, also without any special safety device, once there is the dangerous situation such as wall caving, roof fall in roadway construction, driver faces great security threat.
Utility model content
According to the handling characteristics of fully-mechanized digging machine in bauxite tunnelling, to the harm that driver may cause, mainly the dangerous situation such as wall caving, roof fall cause from the rock etc. above top or side, the utility model provides a kind of bauxite tunnel fully-mechanized digging machine construction driver's cabin safety device.
The technical scheme that the utility model adopts is:
A kind of bauxite tunnel fully-mechanized digging machine construction driver's cabin safety device, comprise the support be installed on described driver's cabin and the protected apron be positioned at directly over described driver's cabin, the side of described protected apron is connected with described holder pivots, described protected apron is downward-sloping gradually to the front of driver's cabin from the rear of driver's cabin, more than one is provided with for supporting the energy-absorbing connecting rod of described protected apron between described protected apron and described support, one end and the described protected apron of described energy-absorbing connecting rod are hinged, and the other end and the described support of described energy-absorbing connecting rod are hinged.
As optimal technical scheme of the present utility model, described energy-absorbing connecting rod comprises the sleeve of first connecting rod, second connecting rod and hollow, one end and the described protected apron of described first connecting rod are hinged, one end and the described protected apron of described second connecting rod are hinged, the other end of described first connecting rod and the other end of second connecting rod are plugged in the two ends cavity of described sleeve respectively, and the middle part of described sleeve is provided with the damping block offseted with described first connecting rod and second connecting rod.
As optimal technical scheme of the present utility model, described first connecting rod is communicated with sleeve internal cavity and extraneous via with second connecting rod is provided with.
As optimal technical scheme of the present utility model, described support installing is at the rear of described driver's cabin.
The beneficial effects of the utility model are:
1, whole device is simple and easy, directly can adopt the method for common welding, be arranged on driver's cabin back easily, can not have any impact simultaneously, can not have influence on the performance of fully-mechanized digging machine to the sight line of driver, does not need to improve fully-mechanized digging machine.
2, security protection is effective.Owing to have employed energy-absorbing connecting rod, can guarantee that greater weight rock drops on after on protected apron, have certain buffering; energy major part is absorbed; both can not cause the damage of protected apron, and also can not produce protector and destroy, play again the object of protection driver simultaneously.
3, use cost economy.The material that this device adopts is all common used material, does not need proprietary material to form by processing and fabricating, has good economic benefit and application value.

Detailed description of the invention
Below with reference to specific embodiment and Figure of description, the utility model is described in further details.
With reference to accompanying drawing 1, a kind of bauxite tunnel fully-mechanized digging machine construction driver's cabin safety device, comprises the support 2 be installed on described driver's cabin and the protected apron 1 be positioned at directly over described driver's cabin.Support adopts the steel pipe manufacturing of diameter 8cm to form, and the steel plate that protected apron adopts thickness to be not less than 2cm thick is made.Side and the described support 2 of described protected apron 1 are rotationally connected, described protected apron 1 is downward-sloping gradually to the front of driver's cabin from the rear of driver's cabin, more than one is provided with for supporting the energy-absorbing connecting rod 3 of described protected apron 1 between described protected apron 1 and described support 2, one end and the described protected apron 1 of described energy-absorbing connecting rod 3 are hinged, and the other end and the described support 2 of described energy-absorbing connecting rod 3 are hinged.
As shown in Figure 2, wherein first connecting rod 301, second connecting rod 302 and sleeve 303 all adopt steel pipe support to the structure of energy-absorbing connecting rod, and damping block adopts rubber or plastic production.One end and the described protected apron 1 of described first connecting rod 301 are hinged, one end and the described protected apron 1 of described second connecting rod 302 are hinged, the other end of described first connecting rod 301 and the other end of second connecting rod 302 are plugged in the two ends cavity of described sleeve 303 respectively, and the middle part of described sleeve 303 is provided with the damping block 304 offseted with described first connecting rod 301 and second connecting rod 302.Described first connecting rod 301 is communicated with sleeve internal cavity and extraneous via 305 with second connecting rod 302 is provided with.
The protective mechanism of this device is, once drop on the protected apron above driver's cabin from the rock above top or side, the rapid action of energy-absorbing connecting rod, energy-absorbing connecting rod is shunk, two connecting rods of energy-absorbing connecting rod inwardly extrude, due to the existence of damping block, the large energy that the rock dropped on protected apron produces can be sponged.Because protected apron has certain inclination angle, add the existence of energy-absorbing connecting rod, can ensure that rock drops along protected apron front, avoid driver.
