The device is composed of fully mechanized coal-mining supports, an operating valve handle, hook-shaped groove plates, a hook-shaped groove, long rod studs and nuts. The device is characterized in that the hook-shaped groove plates are fastened to the two sides of the fully mechanized coal-mining supports, the hook-shaped groove plates are provided with upper hook-shaped grooves and lower hook-shaped grooves, the hook-shaped grooves in C shapes on one side correspond to the hook-shaped grooves in reversed C shapes on the other side, the lower ends of the upper hook-shaped grooves and the upper ends of the lower hook-shaped grooves are in clamping head shapes, the long rod studs and the nuts are matched and respectively arranged in the upper hook-shaped grooves and the lower hook-shaped grooves. As it is shown in picture 1, the hook-shaped groove plates 3 are fastened to the two sides of the fully mechanized coal-mining supports 1, the hook-shaped groove plates 3 are provided with upper hook-shaped grooves and lower hook-shaped grooves 4, the hook-shaped grooves 4 in C shapes on one side correspond to the hook-shaped grooves 4 in reversed C shapes on the other side, the lower ends of the upper hook-shaped grooves 4 and the upper ends of the lower hook-shaped grooves 4 are in clamping head shapes, the long rod studs 5 and the nuts 6 are matched and respectively arranged in the upper hook-shaped grooves 4 and the lower hook-shaped grooves 4.
Description
Technical field
The utility model relates to fully mechanized mining supporter blocking device, relates in particular to a kind of mechanized coal mining bracket control valve handgrip blocking device, belongs to mining fully-mechanized mining equipment technical field.
Background technology
At present; the fully mechanized mining supporter that most of coal enterprise are used mainly contains hydraulic shield support, standing shield hydraulic support; various model hydraulic chock running valves are without any latch-up protection; control valve handgrip is outside exposed; in work plane coal mining process, exist control valve handgrip by misoperation situation, serious threat is the face of the adopting staff of its lower work.Therefore the fortification of hindering that occur because of the non-artificial misoperation of control valve handgrip also once had and occurred, and for avoiding, due to the non-artificial misoperation of fully mechanized mining supporter control valve handgrip, casualty accident occurs, had designed the utility model exploratoryly.
Summary of the invention
The purpose of this utility model is to solve the non-artificial misoperation of above-mentioned fully mechanized mining supporter control valve handgrip and the technical problem of casualty accident occurs, provide a kind of security hidden trouble blocking device of causing because of support misoperation effectively stopped, to overcome the deficiency of above-mentioned technology.
For achieving the above object, technical solution adopted in the utility model is: a kind of mechanized coal mining bracket control valve handgrip blocking device, formed by fully mechanized mining supporter, control valve handgrip, hook frid, hook groove, stock double-screw bolt, nut, it is characterized in that hook frid is fastened on fully mechanized mining supporter both sides, hook frid has upper and lower hook groove, one side hook groove is C font and opposite side hook groove, and to be the font of falling C corresponding, upper hook groove lower end, lower hook groove upper end are dop shape, and stock double-screw bolt mates with nut and is placed in respectively in upper and lower hook groove.
The beneficial effects of the utility model: adopt two bars, two plate hook type groove structure, simple in structure, in fully mechanized mining supporter operating valve group, adopt hook groove fastening, safe and reliable, easy for installation, locking, release are time saving and energy saving, convenient and swift, from having improved in essence the safety of fully mechanized mining supporter, operating efficiency is high, has effectively stopped the potential safety hazard causing because of support misoperation.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.1, fully mechanized mining supporter; 2, control valve handgrip; 3, hook frid; 4, hook groove; 5, stock double-screw bolt; 6, nut.
The specific embodiment
As shown in Figure 1, a kind of mechanized coal mining bracket control valve handgrip blocking device, formed by fully mechanized mining supporter, control valve handgrip, hook frid, hook groove, stock double-screw bolt, nut, hook frid 3 is arranged on fully mechanized mining supporter 1 both sides, hook frid 3 is provided with upper and lower hook groove 4, one side hook groove 4 is C font and opposite side hook groove 4, and to be the font of falling C corresponding, upper hook groove 4 lower ends, lower hook groove 4 upper ends are dop shape, and stock double-screw bolt 5 mates and is arranged on respectively in upper and lower hook groove 4 with nut 6.
After moving frame or when support overhauls, should in time fully mechanized mining supporter 1 control valve handgrip 2 be placed in to interposition (zero-bit) and locking, make fully mechanized mining supporter 1 that the phenomenon of support misoperation can not occur in any case again, essential guarantee is provided to work plane staff's safety.
The operating principle of mechanized coal mining bracket operating valve set blocking device: existing fully mechanized mining supporter 1 control valve is a cross valve, its major function is the flow direction that changes hydraulic system inner high voltage hydraulic fluid.To control the action of fully mechanized mining supporter 1 each column, the various actions of fully mechanized mining supporter 1, displacement process all need to handle control valve and realize, and control valve handgrip 2 must be in zero-bit.In the time not needing to handle fully mechanized mining supporter 1, just control valve handgrip 2 is latched in zero-bit; Row release again need to handle fully mechanized mining supporter 1 time.
Locking process: when fully mechanized mining supporter 1 does not need to move, stock double-screw bolt 5 is mated to the dop place being arranged on respectively in upper and lower hook groove 4 with nut 6, fastening two inner screw nuts 6 are fixed two stock double-screw bolts 5 respectively, and the control valve handgrip 2 in it is fixed, thereby cannot handle fully mechanized mining supporter 1.Therefore realize the in use essential safety of control valve handgrip 2 of fully mechanized mining supporter 1, initiatively avoided the non-artificial misoperation of control valve handgrip 2, fundamentally eliminated potential safety hazard.
Releasing process: need to move fully mechanized mining supporter 1 time, by the stock double-screw bolt 5 that is arranged on respectively the dop place in upper and lower hook groove 4 with mate nut 6, in degree of tightness, pull out respectively or under pull out two for stock double-screw bolts 5 and deposit temporarily and lose in solid dop, control valve handgrip 2 in it is unlocked, and can handle control valve handgrip.
