The specific embodiment
As shown in Figure 1: the hydraulic relief push rod comprises and moves supporter 1, hydraulic cylinder 2 and oil supply mechanism; Said hydraulic cylinder 2 is made up of hydraulic cylinder 12 and piston 13; Said piston 13 adopts the plug formula to be connected with mobile supporter 1; Said oil supply mechanism is connected with said hydraulic cylinder 2 tail ends through connecting oil pipe 9; Said mobile supporter 1 and institute's piston can insert extension bar between stating 13; The two ends of said extension bar have the plug formula interface that is complementary with said mobile supporter 1 and said piston 13; The length of said extension bar is respectively 125mm, 175mm, 275mm; Said oil supply mechanism comprises hydraulic control valve body 3, reversing handle 4, high-pressure oil pipe 5, low pressure pipe 6, fast interface sun mouth 7, the cloudy mouth 8 of fast interface and is connected oil pipe 9; Said hydraulic cylinder 12 rear ends are connected with fixed support body 10; Said hydraulic control valve body 3 is fixed on the outer wall of hydraulic cylinder 12 front ends; Said hydraulic control valve body 3 front ends are connected with reversing handle 4; Said reversing handle 4 rear ends are connected for cloudy mouthful 8 with fast interface sun mouth 7 and fast interface respectively with low pressure pipe 6 through high-pressure oil pipe 5; The axis of the axis of said reversing handle 4 and hydraulic cylinder 12 parallels; Said high-pressure oil pipe 5 all adopts the Kafra fiber material with said low pressure pipe 6.
The course of work of this instance is: the hydraulic relief push rod is vertically placed in the space of supported weight below, is specially and moves supporter 1 end up, fixed support body 10 ends down; Cloudy mouth and Yang Kou with positive mouthful 7 of said fast interface and the cloudy mouthful 8 external manual pump 21 of difference of said fast interface; By manual pump 21 oil pump in the pump oil cylinder 17 is gone into this device; When said reversing handle 4 does not rotate; This device is in reflux state, and the piston 13 in the said hydraulic cylinder 2 does not move, and device is not worked; When said reversing handle 4 is rotated counterclockwise; Oil feeding line is communicated with the oil circuit that leads to hydraulic cylinder 2 back cavities, and the hydraulic oil with certain pressure that is provided by manual pump 21 is through first check valve 16 and promote first hydraulic lock 15 and supply toward hydraulic cylinder 2 back cavities, utilizes the fluid pressure transmission to equate that principle produces bigger external force to the oiling of large end face piston and exports; The hydraulic oil that has certain pressure promotes said piston 13 and moves outside hydraulic cylinder 2 along axis; Second check valve 18 is opened in the motion of said first hydraulic lock 15 simultaneously, and hydraulic oil is released from hydraulic cylinder 2 ante-chambers under the promotion of said piston 13, and manual pump 21 stops pump oil when the front end that moves supporter 1 closely contacts with supported objects; If when piston when hydraulic cylinder 2 front ends reach maximum distance; When the front end of mobile supporter 1 still can't contact with supported object, need insert extension bar this moment, and said mobile supporter 1 is pulled up from said connecting rod; Extension bar one end is inserted connecting rod, and the other end inserts and moves supporter 1; Device is accomplished support work at this point.When said reversing handle 4 turns clockwise; Oil feeding line is communicated with the oil circuit that leads to hydraulic cylinder 2 ante-chambers; The hydraulic oil with certain pressure that is provided by manual pump 21 is through second check valve 18 and promote second hydraulic lock 19 and supply to utilize above-mentioned principle toward hydraulic cylinder 2 ante-chambers, through the hydraulic oil transmission and amplify pressure; Promoting said piston 13 moves in hydraulic cylinder 2 along axis; First check valve 16 is opened in the motion of said second hydraulic lock 19 simultaneously, and hydraulic oil is released from hydraulic cylinder 2 back cavities under the promotion of said piston 13, and this moment, device was in contraction state.In the device course of work; The utlity model has 3 safety valves, be respectively logical ante-chamber tubing safety valve 11, logical back cavity tubing safety valve 14 and oil-feed tubing safety valve 20, when the oil circuit superpressure; Safety valve is opened the overflow pressure release, with the potential safety hazard of avoiding causing because of superpressure.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
