A kind of three corbel type double-column lifters
The present invention relates to gasoline engine equipment technical field, a kind of three corbel type double-column lifters.
Twin post auto lifting machine is a kind of motor vehicle repair and maintains the special-purpose machinery lifting equipment that unit is conventional, and twin columns are lifted
Start is all the main Types of lifting machine, is widely used in maintenance and the maintenance of the compact cars such as car.
Pillar car lift, by saving substantial amounts of ground space while of skyborne for vehicle hoisting, facilitates ground to make
Industry.But the lift arm of twin post auto lifting machine is separate structure, to regulate during use and regulate each respectively
Lift arm, i.e. to adjust four times, work efficiency is greatly reduced, and easily occurs supporting unstable situation, it is impossible to by four
Pallet is the most correctly supported on the tram of chassis, brings hidden danger for support safety.
Prior art uses pallet all use elastomeric material to make, but rubber has oleophylic speciality, when on chassis
When having oil stain or water mark, it is easily caused pallet and skids, affect supporting & stablizing.
Summary of the invention
For drawbacks described above, the present invention proposes a kind of three corbel type double-column lifters.
A kind of three corbel type double-column lifters, including two root posts, the lower end of described column is equipped with motor, in column all
It is provided with the screw mandrel connected by bevel gear with corresponding motor, described screw mandrel is all combined with sleeve, on the medial surface of described sleeve
Being respectively and fixedly provided with placed longitudinally load bearing arm, before and after described load bearing arm, two ends are all provided with a lifting by the way of hinged
Arm, the central authorities of described load bearing arm are all provided with registration arm by the way of hinged, described registration arm are equipped with one along vertically
The horizontal bar hole that direction is through, is all sliding combined with positioning seat in described bar hole, the upper end of described positioning seat is opening
C-type frame upwards.
The middle part of described lift arm is equipped with a through hole the most through, all by hinged in described through hole
Mode connects a rod end joint, and before and after described registration arm, both sides all connect by the way of hinged No. two rod ends
Joint, is all combined with double-head inner thread sleeve pipe between a described rod end joint with corresponding No. two rod end joints.
The lift arm of side and another root lift arm of homonymy are about symmetrical before and after the mesion of load bearing arm.
The invention has the beneficial effects as follows:
The present invention uses two lift arms of the homonymy controlled by a registration arm, and registration arm uses the knot with c-type frame
Structure is held tightly on the longeron on chassis, it is ensured that support safety, prevents chassis from coming off from lift arm easily.Lift arm leads to
Cross threaded mode to be connected with the registration arm of respective side, constitute triangle rock-steady structure, can be that automobile provides stable
While support, can quickly regulate the angle between lift arm and registration arm by rotating double-head inner thread sleeve pipe, thus regulate
Lift arm extension elongation in the horizontal, rapidly adapts to the car body that not consubstantiality is wide.
Accompanying drawing explanation
With embodiment, invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the overall structure schematic diagram of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below right
The present invention is expanded on further.
As it is shown in figure 1, a kind of three corbel type double-column lifters, including two root posts 1, the lower end of described column 1 is equipped with
Motor, is equipped with the screw mandrel connected with corresponding motor by bevel gear in column 1, described screw mandrel is all combined with sleeve 2, described
Being respectively and fixedly provided with placed longitudinally load bearing arm 3 on the medial surface of sleeve 2, before and after described load bearing arm 3, two ends are all by hinged side
Formula is provided with a lift arm 4, and the central authorities of described load bearing arm 3 are provided with registration arm 5, described registration arm 5 by the way of hinged
On be equipped with a horizontal bar hole the most through, described bar hole is all sliding combined with positioning seat 6, by adjust
The joint positioning seat 6 position in bar hole adapts to different automobile types, and the upper end of described positioning seat 6 is the c-type frame of opening upwards.
The middle part of described lift arm 4 is equipped with a through hole the most through, all by hinged in described through hole
Mode connect and have a rod end joint 8, before and after described registration arm 5, both sides all connect by the way of hinged No. two
Rod end joint 9, is all combined with double-head inner thread sleeve pipe 10 between a described rod end joint 8 with corresponding No. two rod end joints 9.
The lift arm 4 of side and another root lift arm 4 of homonymy are about symmetrical before and after the mesion of load bearing arm 3.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
The personnel simply present invention it should be appreciated that the present invention is not restricted to the described embodiments, described in above-described embodiment and description
Principle, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these change and
Improvement both falls within claimed invention.Claimed scope is by appending claims and equivalent circle thereof
