Description

A kind of crank block type automatic lifting suspender
Technical field
The present invention relates to a kind of suspender, particularly a kind of crank block type automatic lifting suspender.
Background technology
Existing roll chocks etc. have the handling mode of the square body hanging piece of centre hole for workpiece being tied up rear overhead traveling crane handling with steel rope.Work of tying up generally is completed by experienced heavy industry, if tie up mode mal, bearing seat may come off and cause danger in handling process.Although this method does not need extra accessory equipment, save cost, the degree of automation of producing is low, professional level is poor, and production efficiency is low, and steel rope is tied up and may be scratched machined surface, workman participates in crane lifting service frequently, easily safety misadventure occurs.
Summary of the invention
In order to solve the problem, the invention provides a kind of crank block type automatic lifting suspender, the technical solution used in the present invention is as follows:
A kind of crank block type automatic lifting suspender, comprise lifting support body 1, fork 2, lifting rod member 3 and slide block 4, it is characterized in that described suspension bracket body comprise crossbeam and be connected to crossbeam two ends and with two columns of beam vertical, guide-track groove 7 offered respectively by described two columns, one end of fork 2 is connected with slide block 4 by bearing pin, described slide block is arranged in described guide-track groove 7 and can slides in vertical direction at guide-track groove, two lifting rod members 3 are rotatably connected to the bottom of two columns respectively by bearing pin, the outer end of described two lifting rod members 3 is rotationally connected by the other end of bearing pin and fork 2.
Further, the center of gravity of described lifting rod member 3 is positioned at inside described suspender.
Further, the shape of described lifting rod member 3 is that inner wide outer end is narrow, and the thickness of described the inner is greater than outer end thickness.
Further, the surface mount of described lifting rod member 3 has nylon layer.
Further, the outer end of described lifting rod member 3 has the handle be threaded connection.
Further, the crossbeam of described suspension bracket body is that rectangle shaped steel 5 is made, described column is welded by two oblong steel plates 6 be oppositely arranged and makes, the sheet steel 8 that between described two oblong steel plates 6 be oppositely arranged, welding is vertical with described oblong steel plate 6, the arranged outside of described column is used for the block 9 lifting by crane rod member 3 described in backstop.

Detailed description of the invention
Below with reference to the accompanying drawings, the specific embodiment of the present invention is described in detail.
Be applicable to the crank block type automatic lifting suspender that rolling mill bearing etc. has the square body workpiece of centre hole, comprising lifting support body 1, fork 2, lifting rod member 3 and slide block 4.Lift by crane support body 1 to be as shown in Figure 1 welded by standard specification rectangle shaped steel 5 and four block length square plates 6, steel plate has guide-track groove 7, has welded sheet steel 8 and connect between every two block plates, to increase rigidity, makes described lifting support body more firm, increases safety factor; As shown in Figure 2, fork 2 one end is linked together by bearing pin and slide block 4; Slide block 4 can be free to slide in the guide-track groove of lifting support body; Lifting rod member 3 uses pin shaft joint with the column bottom of lifting support body 1, can rotate, between two oblong steel plates 6 of described column.The outer end of lifting rod member 3 uses bearing pin to connect with fork 2, and as shown in Figure 5, center of gravity is inside suspender, and lift by crane rod member under normal condition and be in level, surface is adhesive with nylon layer.As shown in Figure 3, whole suspender forms one and plays slider-crank mechanism, can auto-action under gravity, is realized the handling of workpiece by the centre hole of the lifting rod member lifting workpiece that can rotate.
As shown in Figure 4, each several part size:
The lifting width L=1180mm of lifting support body;
Distance between two lifting rod members is l=320mm, and the height to support body is H=1160mm;
Distance between two pin-and-holes of lifting rod member is L2=250mm, and two pin-and-hole sizes are respectively Φ 2=40mm and Φ 3=50mm;
Distance between two pin-and-holes of fork is L1=860mm, and pin-and-hole size is Φ 1=40mm.
Lifting support body is formed by shaped steel and Plate Welding, it has the rail groove of skid.In lifting process, in order to prevent scratching machined surface, be adhesive with nylon layer at lifting rod member mating surfaces.Lifting support body, fork, lifting rod member and slide block constitute slider-crank mechanism, under gravity can auto-action.
As shown in Figure 5, Figure 6, lifting rod member is in horizontality when balance position, so the center of gravity of lifting rod member should be positioned at the inner, lifting rod member shape is that inner wide outer end is narrow, and the inner is slightly thick.The overall process of suspender suspension shaft bearing is: the lifting process starting stage, constantly fall suspender, bearing seat 12 will lift by crane rod member upwards jack-up; Suspender constantly falls, and when the inner is lower than bearing seat centre hole, the free fall of lifting rod member is returned to level attitude; When lifting support body upwards lifts by crane, inner hole of workpiece upper wall held by lifting rod member, sling by workpiece; After bearing seat handling to target location, fall suspender, rotate through thread connection, at the handle 10 of lifting rod member outer end, lifting rod member is turned over upright position, lifting rod member drops to the stop location being welded on upending frame body side surface by self gravitation effect, lifting process terminates.
