Background technique
The driving mode that prior art is used for the lifting roadblock is divided into the all-electric drive unit of built-in integral, and the external hydraulic station drives and built-in split type fluid pressure drive device.Electric pushrod speed is slow, load capacity is low, the shortcoming of poor stability but the all-electric driving lifting of built-in integral roadblock exists.The problem of external hydraulic station drive unit is, owing to be subjected to the restriction of hydraulic station, must adopt centralized driving and control to many roadblocks, the equipment cost of this driving mode and construction cost are all very high, need to lay the hydraulic pipe line of long distance, construction is complicated, potential safety hazard is many, is in when many roadblocks under the situation of intermittent duty, and its energy consumption waste is even more serious.Built-in split type fluid pressure drive device is the driving mode of at present more common heavy lifting roadblock, although adopted the built-in hydraulic power unit that independently to control, because its structure is split type, equipment volume is huge, construction and installation are complicated, later maintenance maintenance difficulty, and cost of production is higher.
Summary of the invention
The purpose of this utility model is a kind of integral hydraulic power plant that are used for cylindricality lifting roadblock that provide at the deficiencies in the prior art.The utility model compact structure, volume are little, construction install convenience, reliable, maintaining is convenient and cost of production is lower.
The concrete technological scheme that realizes the utility model purpose is:
A kind of integral hydraulic power plant that are used for cylindricality lifting roadblock are characterized in that it comprises erection support, hydraulic jack and hydraulic fluid tank, and hydraulic fluid tank is fixedly set in the erection support, and hydraulic jack is located at the top of hydraulic fluid tank; Described hydraulic fluid tank comprises oil hydraulic pump, main valve piece, secondary valve piece and motor, and main valve piece, secondary valve piece are located at the bottom and the top of hydraulic fluid tank respectively, and oil hydraulic pump is located in the hydraulic fluid tank, and motor is connected in the main valve piece, its output shaft is connected with oil hydraulic pump by the main valve piece; The main valve piece is provided with first safety valve and pressure switch and is communicated with oil hydraulic pump by oil circuit, and secondary valve piece is provided with manual release valve and second safety valve and is communicated with oil hydraulic pump, hydraulic jack by oil circuit; Described hydraulic jack is provided with self-limiting mechanism, comprises position limit switch and postive stop baffle.
The utility model compact structure, volume are little, construction install convenience, reliable, maintaining is convenient and cost of production is lower.

Embodiment
Consult Fig. 1, Fig. 2, the utility model comprises erection support 1, hydraulic jack 2 and hydraulic fluid tank 3, and hydraulic fluid tank 3 is fixedly set in the erection support 1, and hydraulic jack 2 is located at the top of hydraulic fluid tank 3; Described hydraulic fluid tank 3 comprises oil hydraulic pump 31, main valve piece 32, secondary valve piece 33 and motor 34, main valve piece 32, secondary valve piece 33 are located at the bottom and the top of hydraulic fluid tank 3 respectively, oil hydraulic pump 31 is located in the hydraulic fluid tank 3, and motor 34 is connected in main valve piece 32, its output shaft is connected with oil hydraulic pump 31 by main valve piece 32; Main valve piece 32 is provided with first safety valve 35 and pressure switch 37 and is communicated with oil hydraulic pump 31 by oil circuit, and secondary valve piece 33 is provided with manual release valve 36 and second safety valve 38 and is communicated with oil hydraulic pump 31, hydraulic jack 2 by oil circuit; Described hydraulic jack 2 is provided with self-limiting mechanism, comprises position limit switch 41 and postive stop baffle 42.
The utility model is to use like this:
Consult Fig. 2, Fig. 3, the installation screw thread of the utility model by hydraulic jack 2 piston rod parts is connected with roadblock lifting rod 4; External electric control box 43 and control switch 44 on motor 34; Be embedded in the integral body of cylindricality lifting roadblock underground.
When roadblock lifting rod 4 rises, press control switch 44, by electric control box 43 starting electrical machinerys 34, driving oil hydraulic pump 31 and driving hydraulic jack 2 through secondary valve piece 33 makes piston rod drive roadblock lifting rod 4 and postive stop baffle 42 risings, touch position limit switch 41 until the bottom of postive stop baffle 42, position limit switch 41 is by electric control box 43 powered-downs, and roadblock lifting rod 4 is in running order, at this moment, the rise state of hydraulic jack 2 is closed by pressure switch 37 and can not be descended.Otherwise, when roadblock lifting rod 4 descends, press control switch 44 once more,, drive oil hydraulic pump 31 and make piston rod drive roadblock lifting rod 4 and postive stop baffle 42 declines through secondary valve piece 33 driving hydraulic jacks 2 by 34 counter-rotatings of electric control box 43 starting electrical machinerys, touch position limit switch 41 until the top of postive stop baffle 42, position limit switch 41 is by electric control box 43 powered-downs, and roadblock lifting rod 4 is in the return state, at this moment, pressure switch 37 is opened, and the pressure in the hydraulic jack 2 is released.
When having a power failure, and roadblock lifting rod 4 is need return to the return state by working state the time, press manual release valve 36, pressure oil in the hydraulic jack 2 is released and flows back to fuel tank, under the effect of roadblock lifting rod 4 deadweights, drive piston rod and postive stop baffle 42 declines, make roadblock lifting rod 4 be in the return state.
When the hydraulic system overburdening, be that roadblock lifting rod 4 is in the working state that part rises, at this moment, meet with that unexpected vehicle rolls or during weight, pressure in the hydraulic jack 2 bears pressure greater than the maximum of system, pressure oil in the hydraulic jack 2 is opened second safety valve 38 through secondary valve piece 33, and system is forced to off-load, makes roadblock lifting rod 4 be in the return state.This measure can avoid hydraulic jack 2 and system pipeline to meet with high pressure and explosion.
