Description
Technical field
The present invention relates to a kind of flexible lifting mechanism of single cylinder of car body correcting machine, be specifically related to a kind of flexible lifting mechanism of kerve single cylinder of car body correcting machine.The flexible lifting mechanism of described kerve single cylinder refers to implement by an oil cylinder lifting mechanism of parallel lifting or inclined lift, and the principal character that realizes inclined lift then is the oval slotted eye that is arranged in the bottom.
Background technology
Lifting mechanism is one of radical function spare of car body correcting machine, and it is used for lifting the workplatform of inspection machine, makes its lifting, so that machine shop van-type vehicle enters workplatform, reaches suitable repair work height.
The flexible lifting mechanism of current newer single cylinder adopts single hydraulic oil cylinder driving, possesses two kinds of functions of parallel lifting or inclined lift.This type of type possesses certain economic and practicality advantage, but also there is following problem in this technology: at first, realize principal character---the oval slotted eye overhead (on platform) of inclined lift, put (being installed on underframe) (seeing the Chinese invention patent that publication number is CN 102701109 A " the flexible lifting mechanism of a kind of single cylinder of car body correcting machine " for details) at the bottom of the elevating ram, the problem of bringing is: because oval slotted eye overhead, platform is when tilting to rise, front arm appears sometimes and preceding go up rotating shaft when the oval slotted eye of no show still is made as the rear arc of determining the parallel attitude of platform just with the phenomenon of platform jack-up, also because oval slotted eye is low early and high after gradient, roughly the same with the hydraulic directio of oil cylinder, near the rotating shaft phenomenon that front end is made a concession oval slotted eye rear arc on front arm preceding can appear in the parallel lifting of the platform starting stage, cause the slow or poor effect of platform leveling, even adopt the also difficult improvement of the extra parallel stop gear that increases.Secondly, owing to put at the bottom of the elevating ram, cylinder thrust acts between base hinged-support and the front arm, and lifting moment is not good, and particularly the initial thrust peak value is higher when low level, needs to strengthen cylinder diameter lifting pressure and just can reach.The third aspect, also exist because the insurance leg device lacks the ratchet locking when the platform parastate, and because the lifting action of the insurance leg device that front and back arrange and oil cylinder lacks the asynchronous problem of clutch that direct correlation brings, and insure comparatively complicated problems of leg device mechanism.

Control function when the button switch of described keypad 28 triggers and control sequential are set by pre-programmed, and it has following feature: described lifting key switch key is namely connected the rising circuit: turn-off first electromagnetic valve 27, connect oil pump 26 when connecting second electromagnetic valve 25; Described parallel decline key switch button is namely connected parallel decline circuit: of short duration connection rising circuit second electromagnetic valve 25 of elder generation, unlatching oil pump 26, stop after the of short duration time-delay, and connect first electromagnetic valve 27 and the 3rd electromagnetic valve 24 again, the parallel decline of platform; The time-delay timing be by the ratchet bar 20-3 of the ratchet fender guard 20 push rod lifting by oil cylinder 18 slide off latched position and time of flicking determined.Described tilt key decline switch only could be connected under the state that travel switch 3 turn-offs; Under the state that travel switch 3 turn-offs, namely connect inclination decline circuit by described inclination decline key switch: of short duration connection rising circuit second electromagnetic valve 25 of elder generation, unlatching oil pump 26, stop after the of short duration time-delay, connect first electromagnetic valve 27 the 3rd electromagnetic valve 24 again, platform inclination descends; Turning on and off of described locking key switch controls the 3rd electromagnetic valve 24 namely turn-offed the 3rd electromagnetic valve 24, opened first electromagnetic valve 27 simultaneously by locking key, but by the then release of parallel decline key switch, recover to connect the 3rd electromagnetic valve 24.
Below by a working cycle enforcement of the present invention is further specified.
The initial condition of platform 13: horizontal minimum altitude state, this moment, travel switch 3 was normal open; Connect power supply, enter parallel lifting pattern.As shown in Figure 1.
1) press lifting key: oil pump 26 starts; oil cylinder 18 oil-feeds are suppressed; platform 13 parallel risings can rise to arbitrary height of setting in the stroke by crawl, and can be locked in minimum altitude to the arbitrary setting operating altitude between the maximum height by ratchet fender guard 20.
2) press parallel decline key: oil pump 26 starts, stop after the of short duration time-delay, one section (preparing for cylinder 19 releases) → the 3rd electromagnetic valve 24 conducting of platform 13 parallel risings earlier, cylinder 19 conductings, connect compressed gas source 23, cylinder 19 flicks ratchet → the 3rd electromagnetic valve 24 of locking and opens, the 13 parallel declines of oil cylinder time-delay release oil return → platform.
In the parallel lifting process of platform, press locking key, the 3rd electromagnetic valve 24 turn-offs, cylinder cutout, platform 13 descends by deadweight, and until locking on the nigh ratchet, the current height of platform 13 is locked to front slide for ratchet 20-2; As continuing lifting, press parallel decline key and get final product release.
The contact that the aft end face that platform 13 continues declines → forearms 7 begins bruising travel switch 3 disconnects until travel switch 3 and just stops decline, is locked in until first pitch that is positioned at ratchet fender guard front end on the correspondence position of parallel minimum altitude of platform 13.Platform 13 current states: platform 13 is in horizontal minimum altitude, and travel switch 3 turn-offs, the 3rd electromagnetic valve 24 turn-offs, second electromagnetic valve 25 continues conducting, and oil cylinder 18 is in packing state; This moment, platform 13 also may be locked in horizontal minimum altitude state if press locking key.
3) when the horizontal minimum altitude state of platform 13, press inclination decline key---this set is to cause excessively in order to prevent from pressing the decline key that platform is unexpected to tilt to descend: ratchet → oil cylinder 18 time-delay oil return release → platforms 13 that one section → cylinder of platform 13 parallel risings earlier 19 flicks locking are that center of turn tilts to descend with the front arc of Convenient table 11 bottoms: front arm 7 in the oval slotted eye of first hinged-support 2 to front slide, vehicle bridge 25 front ends land on the Self-carried type of the base plate platform 13 of the cambered surface of positioning plate 6 contact base 1, and platform 13 front ends tilt to drop to lowest order.As shown in Figure 2.
4) (continued access 3)) press lifting key again, first electromagnetic valve 27 is closed, and 18 oil-feeds of oil pump 26 startup → oil cylinders are suppressed, promote upward to rotate backward centered by the rotating shaft before the front arm 7 → platform 13 is that center of turn tilts to rise with the cambered surface of Convenient table 11; The preceding lower rotary shaft of front arm 7 is along the groove face of the oval slotted eye at the end, preceding high back of first hinged-support slid underneath backward, until the rear arc of withstanding oval slotted eye---platform 13 changes parastate over to, returns to horizontal minimum altitude state, travel switch 3 contacts reset, conducting, and platform 13 finishes tilt mode, gets back to initial condition.As shown in Figure 1.
