Abstract
The utility model discloses a hydraulic transmission opening and closing machine of a valve, which comprises a hydraulic motor; the output shaft of the hydraulic motor is connected with a reducing gear through a transmission coupler, and the output shaft of the reducing gear is connected with a working shaft key with a clamping piece on the lower end through a working coupler; the working shaft is integrated with the working coupler through a universal coupling joint; the output shaft of the reducing gear is provided with a torque sensor; and the working shaft is provided with a counting sensor. The hydraulic transmission opening and closing machine of the valve has the advantages that the structure is simple, the performance is stable, the cost is low, the research and development cost of the whole equipment does not exceed 200,000 yuan, the valve can be opened or closed only by two persons within 15min, thereby greatly reducing the labor intensity of workers, and improving the working efficiency; when large pipe explosion occurs, the valve can be closed conveniently and quickly, thereby reducing the water loss before repair and the leakage ratio; and simultaneously, the hydraulic transmission opening and closing machine of the valve is also applicable in the opening and closing of valves of natural gas, petroleum pipeline and other liquid.
Description
Technical field
The utility model relates to hoist, especially relates to a kind of valve hydraulic transmission hoist.
Background technique
Valve is the important composition equipment of public supply mains, and it has the effect of isolated fault pipeline section rapidly in rush repair, so keep valve to be in good working order all the time, is one of important duty of pipe network department.But because valve is in the moist rugged environment for a long time, often manually can't open and close or open and close very difficulty in the time of need enabling valve, prolong engineering time because reasons such as aging, burn into corrosion cause.In a single day particularly pipeline booster throttle down quickly taking place, leaks in a large number and will cause bigger economic loss.Therefore adopt the machinery Open valve to become the effective ways of head it off, but this type of at present used equipment price is up to ten thousand yuans of 40-50, the unlocking condition ability proper functioning of equipment must be satisfied in the position of valve opening, and narrow limitation is bigger in practical operation.How to solve safety quick labour-saving opening/shutting valve, shorten the sealing time, reduce the production and marketing rate, increase economic efficiency that to be that water undertaking is anxious wait to wish the problem that solves.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, valve hydraulic transmission hoist that applicability is wide.
For achieving the above object, the utility model can be taked following technical proposals:
Valve hydraulic transmission hoist described in the utility model, it comprises hydraulic electric motor, described hydraulic electric motor output shaft links by transmission coupling and speed reducer, and the output shaft of described speed reducer is connected with the work axle key that the underpart has fastener by the work coupling.
Described working shaft combines with described work coupling by universal shaft coupling.Both be not convenient to simultaneously regulate when the position and the degree of depth of control valve, can have solved the concentricity problem of working shaft again.
Described speed reducer output shaft place is provided with torque sensor; Can set the upper and lower limit of moment of torsion in advance, when Open valve strength is excessive, torque sensor will reduce output torque by the pressure of control hydraulic electric motor output, and working shaft is played a protective role.
Described working shaft is provided with counting sensor.Can monitor the valve opening and the closed number of turns intuitively, for the open and close of this type of valve later on provide valuable reference.
Advantage of the present utility model is simple in structure, stable performance, with low cost, the research and development of whole equipment surpass 200,000 yuan, only need 2 people, times to be no more than 15 minutes during operation can to finish the unlatching of valve or close, alleviate working strength of workers greatly, improved working efficiency; When large-scale booster took place, throttle down reduced the preceding current vector of maintenance easily and fast, reduces the production and marketing rate; The utility model also is applicable to the keying of liquid liquid valves such as rock gas, petroleum pipeline simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, valve hydraulic transmission hoist described in the utility model, it comprises the quantitative plunger piston hydraulic electric motor 1 of A2F clino-axis type, described hydraulic electric motor 1 output shaft links by transmission coupling 2 and speed reducer 3, and the output shaft of described speed reducer 3 is connected by spline by the working shaft 6 that work coupling 4 and underpart have fastener 5.
During practical operation, the mounting point of some valve is low excessively, and working shaft 6 can couple together use with many, and for solving the concentricity problem between the many working shafts, described working shaft 6 combines with described work coupling 4 by universal shaft coupling 7.
Described speed reducer 3 output shaft places are provided with torque sensor, and the overload torque that occurs during to Open valve is realized protection, puies forward the setting maximum torque, when the moment of valve opening during greater than setting value equipment will quit work, avoid the excessive damage gate valve of torsion.
Described universal shaft coupling 7 or working shaft 6 are provided with counting sensor, can monitor this valve opening or close how many circles.
The pedestal 8,9 of hydraulic electric motor, speed reducer is fixed on the engineering truck car body, and when hydraulic system drove speed reducer 3 work, the reaction force of generation can act directly on the car body.During work, according to the length that is closed between gate and the hydraulic transmission hoist apart from selection working shaft 6 and universal shaft coupling 7, (or be connected with gate screw mandrel by other links) is connected the fastener 5 of working shaft 6 ends with the screw mandrel end of gate, open hoist, hydraulic electric motor 1 drives speed reducer 3 work by transmission coupling 2, speed reducer 3 drives universal shaft coupling 7, working shaft 6 and the rotation of gate screw mandrel by work coupling 4, when gate reaches the limit, promptly reach on the torque setting and prescribe a time limit, hoist quits work; Otherwise, when closing gate puts in place, promptly reaching under the torque setting to prescribe a time limit, hoist quits work.
