The valve blocks and the valve seat, and the valve blocks and the upper valve block are fastened by bolts; the joint surface of the utility model is sealed by a sealing ring; pump sources comprise a high-pressure pump source and a low-pressure pump source; pressure oil circuits of two valve bodies connected with the pump sources are provided with a one-way valve; the other valve body is provided with a plurality of throttle valves which can realize on-off of the oil circuits and can adjust flow cross sections, and externally connected oil nozzles which correspond to number of the throttle valves are preserved. The hydraulic pump station has the advantages that when one of hydraulic units can not work because of damage, the utility model can also make lifting and translation, and continuous conduct of construction can be hoisted.
Description
The utility model relates to a kind of hydraulic power unit.
In the top act of large-sized object, translation, the lifting engineering construction, when the required active force of top act, translation, lifting was provided with hydraulic actuator, hydraulic power unit was the power source of whole elevator system.By operating console flow, pressure, the direction of hydraulic power unit are controlled during work,, reached the position that safely, stably object is placed designing requirement to realize control to hydraulic actuator speed of action, amount of force and moving direction.
The hydraulic actuator of every hydraulic power unit of traditional hydraulic power unit and its control constitutes the hydraulic unit of a closed loop.In the act of the top of large-sized object, translation, lifting engineering construction, when the expansion of the hydraulic unit of a closed loop or closed loop hydraulic unit all can not satisfy the top act, translation of object, when lifting requires, then increase identical closed loop hydraulic unit successively, until top act, translation, the lifting that can realize object.
The ZL99202815.9 patent provide a kind of can be according to different lifting weights, different lifting engineering, under the situation of not changing any design, can increase or reduce the oil hydraulic pump control valve of institute's control jack quantity easily, but because mutual noninterference between the hydraulic system of each closed loop, when unbalance loading occurring, between the hydraulic system of closed loop, can not coordinate mutually and need whole system is suspended, system can continue construction after the closed-loop element of damaging carried out artificial adjustment, cause the delay of construction, produce unnecessary delay work loss and construction delay loss.
The purpose of this utility model is to provide a kind of removing to increase, to subtract the jack quantity that is controlled easily under the situation that does not change design according to different lifting weights, lifting speed, and the hydraulic power unit that can communicate with one another between each hydraulic power unit.
For reaching above-mentioned purpose, the hydraulic power unit of the utility model comprises pumping source, a plurality of valve bodies, described valve body is by the valve seat that a mounting structure is arranged, intervening valve piece more than 2 or 2 and 1 uuper valve block are formed by stacking, pass through bolton between valve piece and valve seat and valve piece and the valve piece, the mating face of valve piece and valve seat and valve piece and valve interblock seals with seal ring, pumping source comprises high pressure pumping source and low pressure pumping source, it is characterized in that: be provided with one-way valve on the pressure oil circuit of two valve bodies that link to each other with pumping source, be provided with on another valve body and can realize the logical of oil circuit, the disconnected throttle valve that reaches the adjusting passage section, and reserved a plurality of and the corresponding external oil nozzle of throttle valve number.
Owing to taked said structure, the utility model can be according to different engine requests, by different lifting weights, under the situation of not changing any design, promptly can increase or reduce institute's control jack quantity easily, the a plurality of external oil nozzle of being reserved links to each other with another hydraulic power unit B, when one of them hydraulic unit is damaged can not work the time, can close the pressure oil circuit of this unit, throttle valve on the oil circuit, disconnect the pressure oil circuit and the oil circuit of this unit self, and by other hydraulic unit of another hydraulic power unit B it is provided with pressure oil and constitutes oil circuit, the top of object is lifted, translation, lifting is carried out continuously.
Below in conjunction with drawings and Examples structure of the present utility model and feature are further described.
Fig. 1: the utility model hydraulic power unit structure and user mode reference view.
Fig. 2: the valve body 15 of the utility model hydraulic power unit and connection oil nozzle structural representation thereof.
