Portable automatic leveling hydraulic lifting unit
The present invention relates to the automotive service equipement field, more particularly, the present invention relates to the high portable automatic leveling hydraulic lifting unit of a kind of safety factor, precision and efficient.
At present when vehicle maintenance and repair, generally by symmetrically arranged four or four above lifting machines, automobile is praised to certain height, be convenient to the maintainer and keep in repair under car.Due to have vehicle tire pressure difference, construction ground is uneven, each electrical efficiency factor is different and because of the different factors such as voltage difference that produce of cable length, can make lifting machine produce diff-H when work, and this diff-H can cause being produced overbalance by the automobile of lifting, and then might cause the topple hidden danger of personnel casualty accidents of automobile.Therefore, need to carry out leveling to lifting machine, prior art all adopts manually the leveling one by one of every lifting machine, wastes time and energy, and efficient is very low, and precision is not high.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of safety factor, precision are provided
High and can reduce the portable automatic leveling hydraulic lifting unit of labor strength with efficient.
The objective of the invention is to be achieved through the following technical solutions:
A kind of portable automatic leveling hydraulic lifting unit adopts four or four above lifting machines to put the both sides of automobile is symmetrical, and every lifting machine is connected and composed by fixed mount, power unit, hydraulic actuating cylinder, chain pulley seat, sprocket wheel, hoisting chain and movable stand.Captive joint strip check-out console in the pile of described fixed mount, this check-out console is provided with some breach of decile, the upper end of described movable stand is provided with detector switch, described detector switch matches with check-out console, the detector switch of every lifting machine all connects controller by data line, and described controller connects display panel by data line.
Purpose of the present invention can also be achieved through the following technical solutions:
The upper end of described movable stand is provided with chain pulley seat and sprocket wheel, the supporting hoisting chain of described sprocket wheel, and described hoisting chain one end connects movable stand, other end Connection Bracket.The base of one end Connection Bracket of described hydraulic actuating cylinder, other end connection chain wheel seat, the bottom of described fixed mount is arranged with four or more scroll wheel.
Compared with prior art, the present invention has following beneficial effect:
Safety factor, precision and efficient are high and can reduce workman's labour intensity.

In figure: fixed mount 1, power unit 2, hydraulic actuating cylinder 3, hoisting chain 4, check-out console 5, detector switch 6, movable stand 7, controller 8, display panel 9, automobile 10, chain pulley seat 11, sprocket wheel 12.
The specific embodiment
Below in conjunction with drawings and Examples, essentiality content of the present invention is described in further detail:
As depicted in figs. 1 and 2: a kind of portable automatic leveling hydraulic lifting unit, adopt four or four above lifting machines to put the both sides of automobile 10 is symmetrical.As shown in Figure 3: the bottom of lifting machine fixed mount 1 is arranged with four or more scroll wheel, and the convenient operation personnel drag the lifting machine flexible both sides that is placed in automobile.Every lifting machine is connected and composed by fixed mount 1, power unit 2, hydraulic actuating cylinder 3, chain pulley seat 11, sprocket wheel 12, hoisting chain 4 and movable stand 7.Captive joint strip check-out console 5 in the pile of fixed mount 1, this check-out console 5 is provided with some breach of decile, and the bottom of movable stand 7 upper ends is provided with detector switch 6, and detector switch 6 matches with check-out console 5, in check-out console 5 was in detector switch 6 detection ranges, detector switch 6 just can output signal.Have breach on check-out console 5, when just in time detector switch 6 detected breach, detector switch 6 is output signal not, and so forth.The signal that the detector switch 6 of every lifting machine produces all connects controller 8 and calculates by data line, and the data that simultaneously controller 8 calculated connect display panel 9 by data line and show.The upper end of movable stand 7 is provided with chain pulley seat 11 and sprocket wheel 12, the supporting hoisting chain 4 of sprocket wheel 12, and hoisting chain 4 one ends connect movable stand 7, other end Connection Bracket 1.The base of one end Connection Bracket 1 of hydraulic actuating cylinder 3, other end connection chain wheel seat 11.When hydraulic actuating cylinder 3 lifting, the sprocket wheel 12 that drives on chain pulley seat 11 rotates, related hoisting chain 4 operations, and when lifting, work and produce electric signal by check-out console 5 and detector switch 6 thereupon for movable stand 7.
Embodiment: when lifting machine rises operation, power unit 2 makes hydraulic actuating cylinder 3 liftings for hydraulic actuating cylinder 3 fuel feeding, obtain the hoisting force of hydraulic actuating cylinder 3 due to hoisting chain 4, make the movable stand 7 that hoisting chain 4 connects upwards promote, this moment, detector switch 6 was along with movable stand 7 moves together, because check-out console 5 maintains static, calculate and pass through display panel 9 and show thereby the motor message of movable stand 7 detected and convert it into electric signal transmission to lifting machine controller 8.After having calculated lifting machine and exceeding the setting range value, the lifting machine in can value range out of service continues to start the outer lifting machine of value range, and when all lifting machines were all in the setting range value, all lifting machines can continue to move simultaneously.When this leveling process exceeds the setting range value, controller 8 just can stop the operation of all lifting machines automatically.Otherwise the operating process when descending operation is identical.
