Abstract
A hydraulic inverted ventilation latching device for a coal mine vertical air shaft explosion door comprises a double-outlet-head hydraulic piston cylinder, the double-outlet-head hydraulic piston cylinder connected with a hydraulic pump station is arranged on the side of the explosion door and fixed to a wellhole through a supporting base, and a cylindrical idler wheel is arranged at a rod head, close to one side of the explosion door, of a piston rod of the double-outlet-head hydraulic piston cylinder. A hydraulic push rod moves left and right to control an idler-wheel-type lock head to be compressed or retreat from the explosion door, the influences from severe weather, lighting at night and other factors on the whole operation project are avoided through remote monitoring of a machine room, labor intensity of operators is relieved, increased unnecessary time caused by manual operation is shortened, potential safety hazards are eliminated, and safety of mine ventilation is improved. The hydraulic inverted ventilation latching device is simple in structure, high in reliability, convenient to use, and capable of meeting safety requirements of mine ventilation.
Description
Technical field
The utility model relates to a kind of inverted ventilation locker, especially a kind of hydraulic pressure inverted ventilation locker that is applicable to explosion-proof door of coal miine vertical shaft.
Background technology
Vertical ventilating shaft explosion-proof door is the important measures of mine ventilation safety, once when gas or coal-dust explosion occur in down-hole, explosion proof door will be opened by the impact of high-pressure gas wave automatically, to protect main fan to avoid damaging.In the time of inverted ventilation, inverted ventilation locker, in locking state, compresses explosion proof door and it can not be rotated and promote.Original explosion proof door inverted ventilation is made up of several briquettings, is fixed on the edge of a body, can freely rotate, and withholds a body locking when inverted ventilation.All need master worker that briquetting is mentioned to 90-degree rotation at every turn, one end is pressed on explosion proof door and fixes, the in the situation that of undermanned or bad weather, the operation of snap close explosion proof door is consuming time many, and to complete all lockers, extend the operating time having expended very large manpower and materials simultaneously, brought certain trouble to work.Meanwhile, the region at vertical ventilating shaft explosion-proof door place belongs to explosion-proof area, and laying of the equipment such as motor need to be according to safety code, and the equipment of hydraulic pressure does not need to lay on the spot the electric equipments such as motor, has increased safe unfailing performance.
Summary of the invention
The purpose of this utility model is the weak point overcoming in prior art, and a kind of hydraulic pressure inverted ventilation locker of simple in structure, explosion-proof door of coal miine vertical shaft that reliability is strong, time saving and energy saving is provided.
To achieve these goals, hydraulic pressure inverted ventilation locker for explosion-proof door of coal miine vertical shaft of the present utility model, comprise two hydraulic piston cylinders of lifting one's head, at the multiple two hydraulic piston cylinders of lifting one's head that are connected with hydraulic power unit of explosion proof door arranged outside, two hydraulic piston cylinders of lifting one's head are fixed on pit shaft through base for supporting, two lift one's head hydraulic piston cylinder towards the piston rod end of explosion proof door one side be provided with can be together with explosion proof door junction plate leans cylinder roller.
Described multiple two hydraulic piston cylinders of lifting one's head are 4, and symmetry is located on the upending frame of explosion proof door; Described multiple two oil circuits of lifting one's head hydraulic piston cylinder are chained together mutually.
Beneficial effect: the utility model is by hydraulic push rod left and right moving control roller compression or recess explosion proof door, can pass through machine room remote monitoring, avoids bad weather, the impact of the factors such as night lighting on whole operation engineering.Base for supporting is directly fixed on explosion proof door side, is convenient to install and saved space.Artificial with mechanically actuated replacement, for timely inverted ventilation gains time.Reduce operating personnel's labour intensity, reduced the meaningless time increasing because of manual operation, eliminated potential safety hazard, improved the safety of mine ventilation.It is simple in structure, reliability is strong, easy to operate, can meet the security needs of mine ventilation.
Accompanying drawing explanation
Fig. 1 is partial structurtes schematic diagram of the present utility model;
Fig. 2 is layout of the present utility model.
In figure: the two hydraulic piston cylinders of lifting one's head of 1-, 2-cylinder roller, 3-base for supporting, 4-pit shaft, 5-explosion proof door, 6-oil pipe.
The specific embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described:
As shown in Figure 1, the utility model is for the hydraulic pressure inverted ventilation locker of explosion-proof door of coal miine vertical shaft, is mainly made up of two hydraulic piston cylinders 1, hydraulic power unit of lifting one's head; The two hydraulic piston cylinders 1 of lifting one's head that are connected with hydraulic power unit in explosion proof door 5 arranged outside, two hydraulic piston cylinders 1 of lifting one's head are for double rod cylinder, and side employing connects soon piece and is directly connected with oil pipe, can realize the left and right bidirectional-movement of piston.Described two hydraulic piston cylinders of lifting one's head are 4, and symmetry is located on the upending frame of explosion proof door 5.4 two oil circuits of lifting one's head hydraulic piston cylinder 1 are chained together mutually, as shown in Figure 2; Two hydraulic piston cylinders 1 of lifting one's head are fixed on pit shaft 4 through base for supporting 3, two lift one's head hydraulic piston cylinder 1 towards the piston rod end of explosion proof door 5 one sides be provided with can be together with explosion proof door junction plate leans cylinder roller 2, cylinder roller 2 can well agree with explosion proof door, the well safety of protective device, be convenient to compress explosion proof door in the time of snap close state, prevent its movement; In the time of mine normal production, mechanism is in recessing the state of explosion proof door.
In the time of needs inverted ventilation, start pumping plant and make hydraulic stem positive movement,, towards the direction motion of explosion proof door 5, hydraulic push rod stretches out compression explosion proof door, and device is in snap close state.
In the time that inverted ventilation finishes, start pumping plant and make hydraulic stem counter motion, make explosion proof door 5 remove snap close state, when pushrod movement is to explosion proof door outside, do not affect when explosion proof door 5 is normal to be opened and closed, close pumping plant.
