Abstract
The utility model provides a pair of curtain formula safety device is rolled up to elevating conveyor pan feeding mouth belongs to the comprehensive caving coal working face elevating conveyor technical field that adopts in colliery. That mainly solves prior art exists the problem of major safety risks when reprinting overhaul of the equipments or personnel, and including support, reel, protection network and reel blocking device, its characteristics are: the reel spanes elevating conveyor both sides case groove frid, and it is through axis of rotation and leg joint, the support rigid coupling is on elevating conveyor case groove, reel blocking device sets up and is located the homonymy at reel one end and handle, the handle rigid coupling is at the tip of reel axis of rotation, protection network one end and reel rigid coupling, other end freedom is flagging, and at ordinary times, its roll is on the reel, and its lower extreme hangs down to being close elevating conveyor case groove tank bottom during the use. Full section safety protection is carried out to elevating conveyor pan feeding mouth, the emergence of the injured and fatality incident that the elevating conveyor leads to can be avoided going into because of personnel's mistake.
Description
Technical field
The utility model belongs to coal mine fully-mechanized mining top-coal caving face elevating conveyor technical field, is specifically related to a kind of elevating conveyor feeding mouth roller shutter type safety device.
Background technology
Comprehensive extracting and caving face is when carrying out overhaul of the equipments, the personnel of transporter head can overhaul frequently by elevating conveyor or to elevating conveyor, although perform power failure locking measure, but still have potential potential safety hazard, the error starting of equipment all can be drawn in elevating conveyor people, the hammer mill being positioned at feeding mouth front then can cause fatal harm to personnel, there are major safety risks.
Summary of the invention
The utility model object solves prior art Problems existing, provides a kind of and have safety interlocking mechanism can carry out tunneling boring protection a kind of elevating conveyor feeding mouth roller shutter type safety device to elevating conveyor feeding mouth.
The utility model is solve the problems of the technologies described above the technical scheme taked to be:
A kind of elevating conveyor feeding mouth roller shutter type safety device, comprise support, reel, protective screening and reel blocking device, be characterized in: described reel is across elevating conveyor both sides case groove frid, and it is connected with support by turning cylinder, described support is fixed in be reprinted on cabinet groove; Described reel blocking device is arranged on reel one end and handle is positioned at homonymy, and described handle is fixed in the end of spool turns axle; Described protective screening one end and reel affixed, the other end is freely sagging, and at ordinary times, it twists on reel, and during use, its lower end is hung down to close to reprinting cabinet groove bottom land;
Described protective screening is formed by connecting by metal circular ring chain;
Described protective screening size of mesh opening is 300 × 400mm;
Described reel blocking device is tooth ratchet mechanism;
The below of described reel is provided with the guide strip preventing protective screening swipe.
The utility model compared with prior art, has following beneficial effect:
Because the utility model adopts roller shutter type protective screening, tunneling boring security protection is carried out to elevating conveyor feeding mouth, the generation of the personal injury event caused because personnel are strayed into elevating conveyor can be avoided.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of elevating conveyor feeding mouth roller shutter type safety device, comprise support 1, reel 2, protective screening 5 and reel blocking device, be characterized in: described reel 2 is across elevating conveyor both sides case groove frid, it is connected with support 1 by turning cylinder, and described support 1 is fixed in be reprinted on cabinet groove 6; Described reel blocking device is arranged on reel 2 one end and handle 4 is positioned at homonymy, and described handle 4 is fixed in the end of reel 2 turning cylinder; Described protective screening 5 one end and reel 2 affixed, the other end is freely sagging, and at ordinary times, it twists on reel 2, and during use, its lower end is hung down to close to reprinting cabinet groove bottom land;
Described protective screening 5 is formed by connecting by metal circular ring chain;
Described protective screening 5 size of mesh opening is 300 × 400mm;
As shown in Figure 2, described reel blocking device is tooth ratchet mechanism;
The below of described reel 2 is provided with the guide strip 3 preventing protective screening 5 swipe.
The course of work, when overhaul of the equipments, when needing by elevating conveyor or elevating conveyor is overhauled, lift ratchet 8, now, extension spring 7 is stressed, turning handle 4, puts down protective screening 5, until the lower end of protective screening 5 is close to the bottom of reprinting cabinet groove 6, realize tunneling boring to be blocked by protective screening, ratchet 8 blocks ratchet 9 under the effect of extension spring 7; When elevating conveyor prepares to run well, turning handle 4, regains protective screening 5, and ratchet 8 is under the effect of extension spring 7, and restriction ratchet 9 reverses, and protective screening 5 can not put down automatically, and impact normally works.
