The concrete structure of the present embodiment is：
Upper valve body 10 is fixed in lower valve body 1 by hexagon socket head cap screw 1, and the center of upper valve body 10 is provided with mounting hole, in mounting hole
Valve rod 19, briquetting 15 are installed, briquetting 15 is provided with centre bore, and the lower end in hole is stepped, and valve rod 19 passes through the hole of briquetting 15
Lower end is together by a threaded connection with valve head 20, and valve head 20 is stretched into lower valve body 1 in the working chamber opened, briquetting 15 and upper valve
Upper spring 18 is housed between body 10, lower spring 21 is housed between valve head 20 and briquetting 15, lid 12 is solid by hexagon socket head cap screw 2 13
The upper end of upper valve body 10 is scheduled on, the centre bore of briquetting 15 through lid 12 is installed, and sealing 2 14 is provided between lid 12 and upper valve body 10,
Sealing 3 16 is installed, the top of briquetting 15 is provided with sealing 4 17, between valve head 20 and upper valve body 10 between briquetting 15 and lid 12
Sealing 5 22 is installed, there is sealing 6 23 between valve head 20 and the working chamber of lower valve body 1.
The lower end of lower valve body 1 is provided with sealing pipe screw thread, and one end of pipe joint 2 is sealing pipe screw thread, is screwed in the lower end of lower valve body 1
Pipe screw thread on, the other end of pipe joint 2 is connected by steel pipe or flexible pipe etc. with fluid pressure line.Lower valve body 1 is in left and right ends
Hole is also provided with, piston 5, which coordinates, to be arranged in the hole, and sealing 1 is used for sealing piston 5 and lower valve body 1, and the tail end of piston 5 passes through
Gland 8 is be hinged with connecting rod 4, and gland 8 is fixed in lower valve body 1 by bolt 9, and crossed strip 7 is housed between gland 8 and piston,
The centre of depression bar 3 is hinged on the end of lower valve body 1, depression bar 3 can along with the rotation of the pin joint of lower valve body 1, one end of depression bar 3 with
Connecting rod 4 is be hinged, and the other end is pressed against on pipe joint 2.
The operation principle of the present embodiment is：
When mobile work platform reaches working position, mobile work platform is fallen, and is pressed onto on briquetting 15, and pressure, briquetting 15 moves down,
Briquetting 15 promotes valve head 20 to move down by upper spring 18, lower spring 21, and also high pressure is not provided to pipe joint 2 in main hydraulic station
When oily, valve head 20 is in the case where briquetting 15 and lower spring 21 act on, and the inclined-plane among lower valve body 1 is close in lower end, by the pipeline in valve body
Block, prevent the hydraulic oil in mobile work platform small-sized hydraulic station flows backwards from becoming owner of in hydraulic station.When main hydraulic station is logical to pipe joint 2
When entering hydraulic oil, hydraulic oil pushes valve head 20 open upwards, and the hydraulic oil of main hydraulic station enters in this valve block pipeline, into upper valve body 10
In chamber, it is passed through by the interstitial hole of briquetting 15 in mobile work platform small-sized hydraulic station, lower spring 21 plays protection mobile work platform pipe
The effect on road, if the hydraulic fluid pressure that is passed through of pipe joint 2 is excessive, the hydraulic oil power upward to valve head 20 is more than lower spring
The 21 valve heads power downward to 20, in the case that briquetting 15 is depressed, valve head 20 is still close to upper valve body 10 so that pipeline is not
It is logical.When mobile work platform rises, in the presence of the hydraulic oil in upper spring 18 and lower valve body 1 of briquetting 15 is upward to valve head 20
Rise, while drive valve head 20 to rise, the pipeline of upper valve body 10 is blocked.
When the hydraulic oil in the fluid pressure line that pipe joint 2 connects has pressure, the hydraulic pressure in lower valve body 1 causes piston
5 are moved out, and piston 5 is again compressed pipe joint by connecting rod 4, depression bar 3, and the pressure of fluid pressure line is bigger, and the compressing pipe of depression bar 3 connects
The power of head is bigger, and anti-loose effect is stronger.When needing to dismantle pipe joint 2, by fluid pressure line pressure release, now in lower valve body 1
Pressure is big as ambient pressure, and piston 5 just moves inwards in the presence of crossed strip 7, and piston 5 is by connecting rod 4 with dynamic pressure
Bar 3 is outside, moves up, and depression bar 3 just no longer compresses pipe joint 2, can back out pipe joint from lower valve body 1.
In the above-described embodiments, mobile work platform turn on automatically valve block realizes the automatic of oil circuit by the on-off action of valve head
Break-make, reliability is high, and the pipe joint auto lock of lower valve body, which sets to set with the break-make of upper valve body, makes connection to hydraulic fluid pressure
Dynamic response, further increase the security of device.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can readily occur in,
It should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
Enclose and be defined.
