Technical field

The utility model belongs to auto hoist technical field, particularly a kind of movable lifting machine for vehicles lifting slide unit with concavo-convex location structure.

Background technology

In vehicle maintenance and repair maintenance facility, movable lifting machine for vehicles has unique value of service because of its alerting ability.The movable lifting machine for vehicles lifting slide unit of prior art, its crossbeam and column are aclinic parallel construction, the lifting trailing arm mating with it hangs on crossbeam while installation, for lifting trailing arm is positioned, on the hook position of lifting trailing arm and the carriage of crossbeam, correspondence is processed with pin-and-hole, on trailing arm hook position and cross beam support frame, in the pin-and-hole of corresponding processing, pin rod and spring are installed, carry out location and the displacement of lifting trailing arm by plug pin rod, in the time of work, due to the lifting trailing arm angle certain with contacting of tire, therefore there is a component laterally to exist, under strained condition, owing to there being certain gap between pin rod and pin-and-hole, and pin rod is determined bit position on lifting trailing arm hook position and cross beam support frame, with the stressed position of lifting trailing arm far and not in one plane, make the deflection of lifting trailing arm larger, in addition, owing to adopting pin rod location, at lifting trailing arm hook position pin hole processing, must widen the size of lifting trailing arm hook, on cross beam support frame, also need correspondence to be processed with pin-and-hole, and pin rod and spring be installed in pin-and-hole, complex structure, heavy, weight and the manufacturing cost of complete machine are increased, mobile ex-situ operations is also inconvenient.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art part, provide a kind of simple in structure, strained condition location is good, is out of shape little, safe and reliable, mobile transposition a kind of movable lifting machine for vehicles lifting slide unit with concavo-convex location structure easily.

The technical solution adopted in the utility model comprises column, crossbeam and hang over 2 of the left and right lifting trailing arm on crossbeam, be arranged on the stepped shaft on column, described column and crossbeam are integrally welded by connecting panel, described crossbeam is oblique cross beam, crossbeam has α inclination angle with respect to column, be processed with the 2 groups of crossbeam grooves in left and right in the bottom of crossbeam dip plane, the horizontal supporting plate of lifting trailing arm that described lifting trailing arm has a lifting trailing arm riser and is welded as a whole with lifting trailing arm riser, lifting trailing arm riser has a lifting trailing arm dip plane consistent with the α inclination angle of crossbeam dip plane, the lifting trailing arm projection positioning insert crossbeam groove in the time that the bottom of the horizontal supporting plate of lifting trailing arm is processed with assembling in.

Described crossbeam is 10 °～13 ° with respect to the α inclination angle of column.

On described lifting trailing arm riser, be welded with lifting trailing arm handle.

The lifting trailing arm of processing on described lifting trailing arm riser is linked up with as to link up with without pin-and-hole.

2 groups of the left and right crossbeam groove of the described bottom in crossbeam dip plane processing, every group of crossbeam groove has 5～7.

Compared with prior art, the beneficial effects of the utility model are:

(1) due to the lifting trailing arm of the removable transposition that employing has the lifting slide unit crossbeam of dip plane and match with its dip plane, when work under the effect of load, lifting trailing arm dip plane and crossbeam dip plane close contact, area of thrust surface are increased, within 2 in several crossbeam grooves of the trailing arm of lifting simultaneously projection insertion oblique cross beam, limit the lifting trailing arm that the component laterally that produces due to the lifting trailing arm angle certain with contacting of tire causes and moved distortion outward, therefore make lifting trailing arm location good, be out of shape little, safe and reliable;

(2) owing to having cancelled the pin rod location of lifting trailing arm hook position and hoisting crossbeam, can adopt without pin-and-hole and link up with, and no longer use pin rod and spring, reduced number of parts, structure is simpler, and mobile ex-situ operations is more convenient, simultaneously need to be on the carriage of the hook position of trailing arm and crossbeam corresponding pin hole processing, reduce manufacturing cost, reduced the width dimensions of hook, the corresponding weight of also having saved material and having alleviated complete machine.
