Description of drawings
Fig. 1 is the embodiments of the invention constructional drawing.
The specific embodiment
can be expressly understood technical spirit of the present invention and beneficial effect more for the inspector that the makes Patent Office especially public; The applicant general elaborates with the mode of embodiment below; But the description to embodiment all is not the restriction to the present invention program, any according to the present invention design done only for pro forma but not substantial equivalent transformation all should be regarded as technical scheme category of the present invention.
Fig. 1 is asked for an interview in
; Provided that shape and size do not receive the diagram restriction but be preferably a support 1 of shape shown; This support 1 has a support chamber 11, and a side of support 1 also pivot be provided with and be used for the vacuum device 6 that also will detail below being arranged in the support chamber 11 and the access door 12 of irritating oily mechanism 7 inspections (maintenance with safeguard).
electric control box 2 is arranged on the top of support 1; And be positioned at a side; This electric control box 2 and above mentioned vacuum device 6, irritate oily mechanism 7 and the following change-over valve that also will detail 5 electrical controls are connected, on electric control box 2, be provided with one group of action button 21.
column 3 is fixed on the top of support 1 with plumbness, and preferred scheme is to expand in the bottom of column 3 to establish a flange 33, with one group of flange fix screw 331 flange 33 and support 1 is fixed.Owing to constitute a column chamber 31 in the short transverse of column 3, and this column chamber 31 communicates with aforesaid support chamber 11, so column 3 is hollow pillar, can column 3 be called column tube by this.Again, offer the pipeline resigning hole 32 that communicates with column chamber 31 in the side of the bottom of column 3, this pipeline resigning hole 32 also can be described as the pipeline entrance hole.
The change-over valve lifting mechanism 4 that
provide preferably but not the structure that definitely is limited to is following: comprise cylinder 41, guide pillar 42, cylinder block 43 and guide pillar seat 44; Cylinder 41 with plumbness and its cylinder block 411 towards an end that is fixed on cylinder block 43 down; And the other end of cylinder block 43 is nested with rotationally on column 3, and fixing with column 3 with cylinder block fixing screw 431.Guide pillar 42 promptly is connected with cylinder block 411 towards a last end towards an end of cylinder 41, and with jam nut 421 locking (qualification), the other end of guide pillar 42 promptly towards under an end captive joint with change-over valve 5.Guide pillar 42 is set on an end of guide pillar seat 44 up or down, and the other end of guide pillar seat 44 is nested with rotationally on column 3, and fixing with column 3 with guide pillar seat fixing screw 441.
The turnover tracheae 412 of
aforesaid cylinder 4 is connected with compressed air source unit such as air pump, and air pump can be arranged in the support chamber 11 and be connected with electric control box 2 electrical controls equally.When cylinder 4 work, when for example cylinder block 411 bounces back, then drive guide pillar 42 to top offset in cylinder body, because guide pillar 42 is captiveed joint with change-over valve 5, therefore drive change-over valve 5 to top offset by guide pillar 42, vice versa.
above mentioned change-over valve 5 is connected with electric control box 2 electrical controls; This change-over valve 5 has extraction pipe interface 51, oiling tube interface 52 gentle liquid interfaces 53; On extraction pipe interface 51, connect an end of extraction pipe 511, and the other end of extraction pipe 511 penetrates column chamber 31 and and then causes from column chamber 31 in the aforesaid support chamber 11 and be connected with the following vacuum device that will describe 6 from pipeline resigning hole 32.On the interface 52 of oiling tube, connect an end of oiling tube 521, and the other end of oiling tube 521 penetrates column chamber 31 and and then causes from column chamber 31 in the aforesaid support chamber 11 and be connected with the oily mechanisms 7 of the following fillings that will explain from pipeline resigning hole 32.Gas-liquid interface 53 is towards support 1 and be fixed with an oiling 531, is fixed with a seal ring 5311 at the end of this oiling 531.
aforesaid vacuum device 6 comprises first motor 61 and vacuum pump 62; First motor 61 is connected with aforesaid electric control box 2 electrical controls; And connect (also can claim to cooperate) with vacuum pump 62; Be fixed on the vacuum pump seat 622 together with first motor 61 by vacuum pump 62, and vacuum pump seat 622 is screwed in support chamber 11.Aforesaid extraction pipe 511 is connected with the interface 621 that vacuumizes of vacuum pump 62.
oily mechanism 7 of aforesaid filling comprises second motor 71, oil pump 72 and oil tank 73; Second motor 71 is connected with aforesaid electric control box 2 electrical controls; And connect with oil pump 72, and oil pump 72 is fixed on the top of oil tank 73, oil tank 73 is fixed in the support chamber 11.According to common practise, the oil pump oil inlet (not shown) of oil pump 72 communicates with the oil tank chamber of oil tank 73.Aforesaid oiling tube 521 connects with the oil pump oil out port 721 of oil pump 72.
applicant combines Fig. 1 to narrate principle of work of the present invention; Understanding for the ease of the public; In Fig. 1, also show hydraulic jack 8, at the outer oil hole 81 that is preset with the shoe cream room injection hydraulic oil that is used between oil cylinder and overcoat that puts of hydraulic jack 8.When will be in shoe cream room during oiling, hydraulic jack 8 be placed with the prone position state on the support platform at top of support 1, and make the position of aforesaid oil hole 81 corresponding to oiling 531.
before oiling, the shoe cream room to hydraulic jack 8 vacuumizes earlier, and degree of vacuum is about 0.02Pa, and promptly negative pressure is 0.02Pa.Concrete process is: select the action button 21 on the electric control box 2 by operating personal, make cylinder 41 work of change-over valve lifting mechanism 4, cylinder block 411 stretches outside cylinder body; It is descending to promote guide pillar 42; Because change-over valve 5 captives joint with guide pillar 42, therefore descending by guide pillar 42 drive change-over valves 5, touch oil hole 81 until oiling 531; And by seal ring 5311 sealings, cylinder 41 quits work.And then first motor, 61 work of vacuum device 6; Vacuumize through extraction pipe 511 and the shoe cream room of change-over valve 5 (solenoid directional control valve) by vacuum pump 62 hydraulic jack 8; Just with the air extraction in the shoe cream room, reach the negative pressure value that is about 0.02Pa of aforementioned setting after, vacuum device 6 quits work; Change-over valve 5 automatic switchovers (gas circuit is switched to oil circuit); Then irritate second motor 71 work of oily mechanism 7 again, oil pump 72 is from oil tank 73 oil suctions, injects liquid oil through the oiling of the gas-liquid interface 53 of oiling tube 521 and change-over valve 5 531 to shoe cream room.Because be servomotor and oil pump 72, second motor 71 is gear type pump, therefore can sets the number of turns that oil pump 72 rotates that for example oil pump 72 is that the delivery quality that gear type pump whenever turns around is 0.6ml according to the volume of the shoe cream room of hydraulic jack.So just, can follow this and confirm the corresponding number of turns, to satisfy injection flow requirement to the shoe cream room of hydraulic jack 8.Irritate after oil accomplishes, aforesaid cylinder 41 reverse operations drive change-over valves 5 by guide pillar 42 and rise, and oil hole 81 is left in oiling 531, stopper (hydraulic jack 8 is equipped with self) is filled in oil hole 81, and the hydraulic jack that will irritate behind the oil is withdrawn support 1.The shoe cream room that the rest may be inferred and can accomplish complying with the hydraulic jack 8 that needs quantity refuels.
In sum, technical scheme provided by the invention has overcome the shortcoming in the prior art, has accomplished the invention task, has objectively embodied the technique effect described in the superincumbent technique effect of the applicant hurdle
