Abstract
The utility model discloses a safe hydraulic support system. A first main jack is surrounded by a protective net to prevent coal mine severe environment such as impaction of rubbles falling from the top of a coal mine and the like damaging the first main jack and accordingly the working life of a hydraulic support is increased and meanwhile a safe air bag is installed on a base of the hydraulic support, so that hydraulic support failure caused by severe production activities inside the mine is prevented, the safe air bag is served as a temporary support for the hydraulic support, the safety of personnel inside the mine is increased, and more time for personnel evacuating is obtained.
Description
Technical field
The utility model relates to a kind of support system of coal mine fully-mechanized mining working, is particularly related to a kind of safe hydraulic pressure mounting system.
Background technology
In the fully-mechanized mining process of subterranean coal, the supporting of its work plane is realized by support system.Support system consists of a plurality of hydraulic supports conventionally, hydraulic support forms bow-shaped structural roughly by that of base, back timber, four connecting rods, pitman arm, because the environment in ore deposit is severe, tend to hydraulic support to produce and destroy, cause potential safety hazard, if there is violent production status in ore deposit, often hydraulic support is subject to impact force for the first time to make it destroyed, thereby the personal safety of personnel in ore deposit is caused a hidden trouble simultaneously.
Utility model content
The technical problem that the utility model solves is to provide a kind of safe hydraulic pressure mounting system of protecting hydraulic support lifting jack and increasing hydraulic support safety, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of safe hydraulic pressure mounting system, comprise base, between described base and back timber, pass through the first main jack and the second main jack chain connection, between described the first main jack and the second main jack, be provided with chain connection at the master connecting-rod at back timber middle part, the bottom of master connecting-rod connects base by two slave connecting rods, the afterbody of described back timber connects tail boom, between tail boom and back timber, pass through secondary jack chain connection, tail boom adopts body structure, its underpart is expanded letter structure, in before the upper surface of described back timber, rear three positions are equipped with colliding sensor, described colliding sensor is electrically connected to and is arranged on the gas generator on base, the gas outlet connecting safety air bag of gas generator, described the first main jack is provided with catch net outward, the two ends of catch net respectively be connected base and back timber chain connection.
As preferably, described catch net is collapsible.
Beneficial effect: the utility model utilizes catch net that the first main jack is surrounded; prevent the destruction that the adverse circumstances in colliery cause the first main jack; rubble shock falling as top, hole, ore deposit rubble etc.; increased the working life of hydraulic support; on the base of hydraulic support, air bag is installed simultaneously; prevented the malfunctioning of the hydraulic support that in ore deposit, violent activity in production causes; now by air bag, hydraulic support is carried out to an of short duration support; increase the safety of personnel in ore deposit, for personnel withdraw the more time of striving for.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: base 1, the main jack 3 of catch net 2, first, gas generator 4, air bag 5, the main jack 7 of slave connecting rod 6, second, tail boom 8, secondary jack 9, master connecting-rod 10, colliding sensor 11, back timber 12.
The specific embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
A kind of safe hydraulic pressure mounting system, comprise base 1, between described base 1 and back timber 12, pass through the first main jack 3 and the second main jack 7 chain connections, the first main jack 3 and the second main jack 7 play the effect of lifting back timber 12, between described the first main jack 3 and the second main jack 7, be provided with chain connection at the master connecting-rod 10 at back timber 12 middle parts, the bottom of master connecting-rod 10 connects by two slave connecting rods 6 stability that base 1 is used for increasing this system, the afterbody of described back timber 12 connects tail boom 8, between tail boom 8 and back timber 12, pass through secondary jack 9 chain connections, tail boom 8 adopts body structure, its underpart is expanded letter structure, tail boom 8 is convenient to large area by the adjusting of secondary jack 9 and is propped up body of wall increase stability, in before the upper surface of described back timber 12, rear three positions are equipped with colliding sensor 11, described colliding sensor 11 is electrically connected to and is arranged on the gas generator 4 on base 1, the gas outlet connecting safety air bag 5 of gas generator 4, the outer catch net 2 that is provided with of described the first main jack 3, the two ends of catch net 2 respectively be connected base 1 and back timber 12 chain connections.
As preferably, described catch net 2 is collapsible, is convenient to packing up of hydraulic support.
The utility model utilizes catch net 2 that the first main jack 3 is surrounded; prevent the destruction that the adverse circumstances in colliery cause the first main jack 3; rubble shock falling as top, hole, ore deposit rubble etc.; increased the working life of hydraulic support; on the base 1 of hydraulic support, air bag 5 is installed simultaneously; prevented the malfunctioning of the hydraulic support that in ore deposit, violent activity in production causes; now by 5 pairs of hydraulic supports of air bag, carry out an of short duration support; increase the safety of personnel in ore deposit, for personnel withdraw the more time of striving for.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
