Abstract

The utility model discloses a large porous part dedicated hanger, which comprises a sliding rod, at least two clamping jaws, a clamping jaw support, a sliding sleeve and a locking device, wherein the upper ends of the clamping jaws are connected with the sliding sleeve, and a barb is arranged at the outer side of the lower end of the clamping jaw; the sliding rod passes through the sliding sleeve and can slide up and down relative to the sliding sleeve, and a lifting lug is fixed at the upper end of the sliding rod; the lower end of the sliding rod is fixedly connected with the clamping jaw support, and the locking device is connected with the sliding sleeve and locks the sliding rod; and the clamping jaws are propped against the clamping jaw support. The gravity of hole parts is converted into the tension of the tool jaws, thereby achieving the hanging and unloading effects; and the large porous part dedicated hanger is matched with a traveling crane and other hoisting equipment to easily lift and unload large hole parts, thereby not only saving labor, but also shortening the construction time and improving the efficiency.

Description

Large-scale part special hanger with holes

Technical field

The utility model relates to a kind of suspender, is specifically related to a kind of large-scale part special hanger with holes.

Background technology

Existing large-scale part with holes, for example bearing and sleeve part often use in industrial process, but the hanging method of bearing class part is very single, basically all be to use steel rope, if run into the situation that bearing or sleeve part cooperate with his thing, because of making its lifting become quite difficult by reeve.

Especially in smelting iron and steel industry maintenance process, frequently run into the bearing carrier ring field-strip, and can't reeve in unloading process, therefore adopt steel rope hanging method commonly used just can't reach the purpose of lifting, be badly in need of the new lifting device of making.

Summary of the invention

Technical problem to be solved in the utility model is for the lifting problem that solves large-scale part with holes provides a kind of part special hanger large-scale with holes easy to use, to overcome the above-mentioned defective that prior art exists.

The technical scheme of the utility model technical solution problem is as follows:

A kind of large-scale part special hanger with holes is characterized in that, comprises slide bar, claw, claw support, sliding sleeve and blocking device;

Described claw has two at least, and its upper end is rotationally connected with on the sliding sleeve, and the lower end of claw outwards is provided with barb;

Described slide bar passes relatively in the sliding sleeve that sliding sleeve slides up and down, and the slide bar upper end is fixed with hanger, and the slide bar lower end is connected with the claw support fixation;

Described blocking device is connected on the sliding sleeve slide bar is locked;

Described claw is resisted against claw and supports.

By above disclosed technical scheme as can be known: owing to claw supports by claw, and the claw support changes with the change in location height of slide bar in sliding sleeve, and then makes the opening angle of claw change.

The utility model is converted into the tension force of instrument claw by the gravity with part with holes, unloads effect thereby reach to hang; Structure of the present utility model in addition is the slide block leverage, and is effectively simple, and easy operating adopts the large-scale part special hanger with holes of the utility model can cooperate driving to wait weight-lifting equipment to hang easily and unloads large-scale part with holes.Not only save labour power, and shortened the engineering time, improved efficient.

The specific embodiment

Further specify the utility model below in conjunction with accompanying drawing and specific embodiment.

As shown in Figure 1 and Figure 2, the large-scale part special hanger with holes of the utility model comprises slide bar 1, claw 2, claw support 3, sliding sleeve 4 and blocking device 5;

Described claw 2 has three, serves as that axle is coniform uniform setting with the suspender center, and claw 2 upper ends are rotationally connected with on the sliding sleeve 4 by rotating shaft 6, and the outside, the lower end of claw is provided with barb 21;

Described slide bar 1 passes relatively in the sliding sleeve 4 that sliding sleeve slides up and down, and slide bar 1 upper end is fixed with hanger 7, and slide bar 1 lower end is supported 3 with claw and captiveed joint;

Described sliding sleeve 4 sidewalls are provided with tapped bore 41, and described blocking device 5 is the jackscrew handle, and its head is threaded and is contained in the sliding sleeve 4, and when lock-out state, the screw rod of jackscrew handle 5 front portions withstands slide bar 1.

Described claw supports 3 and is provided with three grooves 31, and the claw side leans against in the groove 31.

Using method of the present utility model is as follows:

As shown in Figure 3, tighten jackscrew handle 5 before the lifting, make claw support 3, thereby claw 2 is opened not because of own wt glides.Be suspended to then in the part that need hang the large-scale band through hole that unloads, loosen the jackscrew handle, lifting, claw support 3 and slide bar 1 just bearing or sleeve part can be hung and unload out.

The utility model suspender can lift the part that has through hole, certainly, and by increasing claw and adjusting the part with holes that the claw position can lift other shapes.

Claims

1. one kind large-scale part special hanger with holes is characterized in that, comprises slide bar, claw, claw support, sliding sleeve and blocking device;
