The such as patent No. is 201410486696.3 disclose a kind of lifting machine adjustable rotary hold-down arm again, belongs to lifting machine equipment technical field.It comprises lifting fixed mount, supporting rotary frame and support arm device, supporting rotary frame comprises rectangular-shaped hold-down arm and is located in the middle part of the sleeve of hold-down arm one end, sleeve and is provided with circular hole, be provided with cylindrical bar in circular hole, the cylindrical bar other end be inserted into fixed mount two ends be provided with circular hole after and prop up cylindrical bar by the lower port that circular baffle plate to be fixed on fixed mount circular hole by the second screw; Support arm device comprises trailing arm and is located at the rectangular-shaped base plate of trailing arm lower end, and base plate two Symmetry Edge is equipped with downwards identical " " " shape slide plate, base plate and two symmetrically arranged " " " rectangular channel that forms of shape slide plate and rectangular-shaped hold-down arm match.The present invention can achieve the position adjustability of trailing arm and increase trailing arm moveable face area division, and what be convenient to searching the best lifts position, improves field of application and practicality; And achieve single platform raising.Beneficial effect is obvious, but cannot extend or shorten due to described trailing arm, and cannot be suitable for different automobile types, applicability is not high.
Therefore, work out and a kind ofly use various vehicle and the single-column auto hoist rotary retractable trailing arm of long service life.
Summary of the invention
Utility model object: for the problems referred to above, it is simple that the purpose of this utility model is to provide a kind of structure, long service life, and single-column auto hoist rotary retractable trailing arm applied widely.
Technical scheme: in order to overcome the above problems, the utility model provides a kind of single-column auto hoist rotary retractable trailing arm, for support vehicle limbs, comprise the front trailing arm being divided into the longeron left and right sides, rear trailing arm, described front trailing arm comprises crossbeam, lift mechanism, described crossbeam is installed vertically on longeron in the horizontal direction, and lift mechanism is installed respectively in the two ends up and down of described longeron, and described lift mechanism is the Collapsible structure be formed by connecting by the 3 sections of section of lifting nested types; The utility model structure is simple, and by being set to lifting structure the Collapsible structure be formed by connecting by the 3 sections of section of lifting nested types, can be elongated or shortened by lift mechanism neatly, to be suitable for different automobile types, practicality is high.
Described lift mechanism is rotary structure.
Described front trailing arm, longeron, rear trailing arm top layer are provided with protective film; Get rusty after avoiding front trailing arm, longeron, the use of butt brachium time, affect equipment performance, the utility model sets up protective film on front trailing arm, longeron, rear trailing arm surface.
Described front trailing arm, rear trailing arm are provided with slipmat, and described slipmat when front trailing arm, rear trailing arm lift automobile, can avoid car skidding, improve device security.
Described slipmat establishes waveform or machicolated form lines, and the utility model is by being set to waveform or machicolated form lines by slipmat, effectively improve the skidproof effect of slipmat, beneficial effect is obvious.
Beneficial effect: compared with prior art, the utility model has the following advantages:
1. applied widely: lift mechanism, by being set to lifting structure the Collapsible structure be formed by connecting by the 3 sections of section of lifting nested types, can elongating or shortening, being applicable to different automobile types by the utility model neatly, applied widely.
2. long service life: the utility model by setting up protective film on front trailing arm, longeron, rear trailing arm, and the infringement can effectively avoiding extraneous environmental pollution, water etc. to cause trailing arm, effectively increases the service life.
