Description
Technical field
The utility model belongs to mine equipment technical field, relates to a kind of linkage lock formula inclined drift tramcar escape-preventing device.
Background technology
The transportation mode often adopted in oblique lane transport is: above inclined gallery, settle winch to draw car-haul material.Due to manual operation and other factors, often occur the disconnected rope of haulage cable, mine car rapidly falls along track, very easily causes injures and deaths and the property damage of personnel.At present, the mode that inclined drift tramcar escape-preventing device mainly adopts has: directly stop that the device of mine car is as arrester, stop buffer, automatic car catcher, crotch stop buffer etc.Indirectly mode has: the speed being detected mine car by infrared detection device, adopts wire net formula stop buffer to keep off a car; Carry out mine car velocity measuring by electromagnetic sensor and time relay, adopt wire rope net bar to keep off a car, its principle is all when after inclined shaft generation derailing accident, moves downward by arranging interception apparatus for blocking mine car in orbit.Its shortcoming is that blocking apparatus can only single use, both wastes material, and destroys again the continuity of coal production.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and provide a kind of linkage lock formula inclined drift tramcar escape-preventing device, it is reasonable in design, and structure is simple, and working stability is reliable, and long service life, operating cost is low, and productive costs is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of linkage lock formula inclined drift tramcar escape-preventing device, comprise the anchor pole of multiple the fixations be fixedly installed on back and base plate, it is characterized in that: also comprise the steady rope one of stabilization protective effect and steady rope two and the rectangular security guardrail one and the rectangular security guardrail two that play protective action; Each described anchor pole end is all installed with single-stranded loop, steady rope one and steady rope two is provided with between described single-stranded loop, described rectangular security guardrail one is provided with on the downside of described steady rope one, described rectangular security guardrail two is provided with on the upside of described steady rope two, pulley is provided with in the middle part of described steady rope one, described pulley is surrounded with stay cord, and described stay cord one end is fixedly connected with described rectangular security guardrail one, and the described stay cord other end is fixedly connected with described rectangular security guardrail two.
Above-mentioned linkage lock formula inclined drift tramcar escape-preventing device, is characterized in that: described steady rope one, described steady rope two and described stay cord are steel rope.
Above-mentioned linkage lock formula inclined drift tramcar escape-preventing device, is characterized in that: the diameter of described steady rope one and described steady rope two is all greater than 18.5mm.
Above-mentioned linkage lock formula inclined drift tramcar escape-preventing device, is characterized in that: the diameter of described stay cord is all greater than 8mm.
The utility model compared with prior art has the following advantages:
(1) design of this linkage lock formula inclined drift tramcar escape-preventing device is very reasonable, and simple and compact for structure, working process is steadily reliable.
(2) this linkage lock formula inclined drift tramcar escape-preventing device long service life, operating cost is low.

Detailed description of the invention
A kind of linkage lock formula inclined drift tramcar escape-preventing device as shown in Figure 1, comprise the anchor pole 1 of multiple the fixations be fixedly installed on back and base plate, also comprise the steady rope 1 of stabilization protective effect and steady rope 24 and the rectangular security guardrail 1 and the rectangular security guardrail 26 that play protective action; Each described anchor pole 1 end is all installed with single-stranded loop 2, steady rope 1 and steady rope 24 is provided with between described single-stranded loop 2, described rectangular security guardrail 1 is provided with on the downside of described steady rope 1, described rectangular security guardrail 26 is provided with on the upside of described steady rope 24, pulley 7 is provided with in the middle part of described steady rope 1, described pulley 7 is surrounded with stay cord 8, and described stay cord 8 one end is fixedly connected with described rectangular security guardrail 1, and described stay cord 8 other end is fixedly connected with described rectangular security guardrail 26.
In the present embodiment, described steady rope 1, described steady rope 24 and described stay cord 8 are steel rope.
In the present embodiment, the diameter of described steady rope 1 and described steady rope 24 is all greater than 18.5mm.
In the present embodiment, the diameter of described stay cord 8 is all greater than 8mm.
The working process of the utility model linkage lock formula inclined drift tramcar escape-preventing device is: first this linkage lock formula inclined drift tramcar escape-preventing device is fixedly mounted on control position, when mine car stops in tunnel, rectangular security guardrail 1 is left behind, rectangular security guardrail 1 drives rectangular security guardrail 26 to rise by stay cord 8, and now rectangular security guardrail 1 and rectangular security guardrail 26 can play actv. protective action.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
