Description
Technical field
The present invention relates to a kind of accessory equipment of half scissors-type vehicle, relate in particular to a kind of half scissors-type vehicle bay-lift of Structure Improvement.
Background technology
Usually Mechanical Help uses bay-lift after vehicle, make car body lift and promote from ground, thereby the various fault key elements to car body place under repair, Mechanical Help is exactly such a device of offering help for the repairing that makes vehicle becomes easily with bay-lift, and according to large being divided into column support type and intersecting level type of frame mode.
Level type (X-type or the scissors-type) bay-lift that intersects is left respectively on the top of a pair of ground framework, and right side is provided with the intersection lever of X font, and the top of intersection lever is provided with the vehicle plummer that can settle vehicle.In order to rise and descend described pair of cross lever, be separately installed with oil pressure cylinder in addition.When thereby the lever that intersects rises and descends by described oil pressure cylinder, and then the vehicle plummer that makes to be placed with vehicle rises and descends.
In the situation of scissors-type bay-lift, the wheel of vehicle is positioned at intersection the outer of lever and places, and two fulcrums carry out the support vehicle plummer from front and back on the top of intersection lever, therefore when vehicles failed is positioned at vehicle plummer length direction middle, weight will roll and annotate to one, thus the problem points that has the vehicle plummer to tilt to length direction.General bay-lift is small-sized, medium-sized, and full size vehicle all carries and uses, and therefore makes total length be positioned at all that to intersect the centre of two strong points before and after lever be impossible in the weight center of different vehicles respectively.In addition, the scissors-type bay-lift enters in the centre of vehicles failed according to vehicle plummer width, but while to lopsidedness, entering, the loading of vehicle will concentrate on a top-cross fork lever, thereby the problem points of vehicle plummer to lateral inclination arranged.The vehicle plummer tilt phenomenon of such scissors-type bay-lift has the problem points brought inconvenience in the operation for example required, as the horizontal degree of precision of wheel calibrating operation (, calibrating operation requires the degree of precision of 0.01 ° of level).
In addition, in the situation that scissors-type bay-lift, operator in the operation of bottom wants for instrument alternately in situation about moving to side, intersected lever or stop and can not move from side direction for the oil pressure cylinder of lift lever, but, in situation about can only outwards extrude from bay-lift, has the inconvenience that makes vehicle need direction forwards, backwards to move.
Pillar (special, four column types) type bay-lift is different from the scissors-type bay-lift, and what have vehicle plummer tilt phenomenon that the unequal distribution of the weight by vehicle is occurred prevents that function is outstanding, operator's the outstanding advantage of side movability.But, the pillar of column support type bay-lift need be wider than the width of vehicle setting, namely in the situation that four column type bay-lifts, pillar position before and after need arranging with the long range difference of the length than vehicle, so the space that bay-lift occupies is large, thereby there is the problem points of effectively applying flexibly that hinders intracardiac space in Mechanical Help.
Summary of the invention
In view of this, the inconvenience that the object of the invention is to provide the side direction of non-efficiency that the space of a kind of tilt phenomenon of the weight timing in unequal minute that has improved the scissors-type bay-lift and four column type bay-lifts applies flexibly and scissors-type bay-lift to move, make it possess simultaneously half scissors-type vehicle bay-lift of the Structure Improvement that the strong point that strong point that the scissors-type bay-lift holds and four column type bay-lifts hold is arranged.
