Description

A kind of bearing hoister

Technical field

The utility model relates to a kind of bearing special hanger.

Background technology

Traditional bearing hoister is the three-jaw suspender of the outer hook of band, must hook the edge of bearing inner ring during its lifting, and the position area that its three pawls contact with bearing is little, and very stiff and demanding, the easy damaged bearing surface.This suspender is when lifting, and just three-jaw holds up the bearing bottom surface, does not push down the bearing upper surface above, easily makes the bearing slippage in hoisting process, can not lift bigger bearing.The flexible of three-jaw controlled by pole, telescopic shaft and bearing pin, during use, need extract bearing pin, telescopic shaft moves down, and dwindles three-jaw and forms round minimum diameter, at this moment insert the bearing pin location, play sling and make it can enter bearing bore diameter smoothly, extract bearing pin then, sling has made progress, make three-jaw touch bearing and picking-up, finish lifting.Its complicated operation use inconvenience, and this hanger structure is simple, narrow application range.

Summary of the invention

The utility model solves the above-mentioned problems in the prior art exactly, and a kind of bearing hoister is provided, and this suspender Applicable scope is wide, and carrying strength is big, not fragile bearing surface.

For addressing the above problem, technical solution of the present utility model is: a kind of bearing hoister, and it comprises hanging scaffold, hanger, attaching parts, connecting rod, tong arm, base, support, suspension hook and pull bar; The hanging scaffold upper end is fixed with hanger, and following end periphery is evenly equipped with the attaching parts more than three, and each attaching parts is hinged with a connecting rod, and the lower end of connecting rod is hinged with tong arm, and the lower end of tong arm is hinged on the inner of base; With the support of connecting rod equal number with the distribution mode identical with connecting rod be distributed on pipe around, the central axes of pipe and hanger, the axis of each tong arm is hinged with support inner end corresponding with it respectively, the outer end of support is hinged with pull bar, and the other end of pull bar is hinged on the outer end of base; The outer end of support is bent downwardly, and the bottom surface in knee is the clamping dish; The lateral surface of base is the circular arc that is complementary with bearing inner wall, and there has been the pallet that can hold up bearing the bottom surface; Be fixed with suspension hook on a connecting rod therein, the clamping projection of suspension hook is arranged on the support of this connecting rod lower end.

The clamping dish of above-mentioned described support, the lateral surface of base and tray upper surface are fixed with polyester sheet respectively.

Pull bar of the present utility model and tong arm have formed a parallelogram lindage, and the effect of this mechanism is to make the base can parallel motion.Its specific operation process is as follows: lifting appliance puts down hanger, makes the downward pressing tongs arm of connecting rod, and tong arm rotates under the axis effect of tong arm, and the tension base moves the base level inwards, reaches hour, and suspension hook hangs up the clamping axle, state as shown in Figure 3.At this moment lifting appliance inserts the bearing inboard with suspender, unclamps suspension hook, and the sling that made progress under the mutual action of connecting rod, tong arm, base, makes base hold up bearing, finishes hoisting process.The contact surface of clamping dish, base and pallet and bearing is big, can not damage bearing surface, the suspender that all is fixed with polyester sheet at the lateral surface and the tray upper surface of clamping dish, base especially, and it more can not damage bearing surface, and carrying strength is big.Little suspension hook of the present utility model is as the keying instrument of suspender, and is simple to operate, easy to use, commonality is good.In a word, the utility model carrying strength is big, and not fragile bearing surface is simple to operate, easy to use, commonality is good, and Applicable scope is wide.
