Abstract

The utility model provides a cast tube hook, and is characterized in that the cast tube hook is a U-shaped hook body; the top of one of two straight levers of the hook body is provided with a rope connecting hole; a rubber (nylon) plate is arranged on the inner face of the other straight lever. The utility model satisfies the special requirements of handling operation of cast tube, thereby achieving the aims of utility, safety, handiness, easy operation for workers and low handling cost and avoiding damage on the cast tube.

Description

Cast tube hook

Technical field

The utility model relates to a kind of suspension hook of unloading, and is not have special tool and a kind of Cast tube hook of design-calculated at the cast tube of unloading originally specifically.

Background technology

Cast tube is in the loading and unloading operation process, and requirement can not damage cast tube surface and cast tube hole inwall screw thread.Originally the cast tube of unloading is used the chemical fibre suspender belt more, and 1, the cost height, every suspender belt cost is scrapped standard more than 1500 yuan according to suspender belt, and suspender belt seriously fluffs, fracture of wire promptly should be scrapped, the shipping and delivery cost height; 2, period of service is short, and the every reusable number of times of suspender belt is below 50 times; 3, inefficiency in workman's operation, needs earlier cast tube to be levered up, and timber wedge on the pad could be put on suspender belt on the bundle hook, and operation is loaded down with trivial details, and efficient is low.

Summary of the invention

The utility model provides a kind of suspension hook of the cast tube of unloading specially, meets the specific (special) requirements of cast tube loading and unloading operation, reaches practical, safe, light, is easy to workman's operation, avoids the low purpose of damage, shipping and delivery cost to cast tube.

The technical solution of the utility model is: a kind of Cast tube hook, it is characterized in that described Cast tube hook is the U-shaped coupler body, in coupler body two straight-bars always the masthead end one rope connecting bore is arranged, rubber (or nylon) plate is set on the inner face of another straight-bar.

Described suspension hook U-shaped coupler body, two straight-bars are acute angle, and opening increases from inside to outside gradually.

The utility model compared with prior art has many advantages and good effect:

1, suspension hook directly hangs on the hole wall of cast tube two ends and can play hook, and is easy to operate, saved and used the loaded down with trivial details of chemical fibre suspender belt binding.Improve production efficiency, reduced cost.

2, suspension hook and cast tube contact site are provided with rubber (or nylon) plate, have avoided the damage to cast tube.

3,, guarantee can not break off relations in the handling process, so be difficult for taking place the safe mass accident because suspension hook is rational in infrastructure.

The specific embodiment

Referring to Fig. 1, Fig. 2, the embodiment of the utility model Cast tube hook is described in detail.A kind of Cast tube hook, described Cast tube hook are U-shaped coupler body 1, in 1 liang of straight-bar of coupler body always the masthead end one rope connecting bore 2 is arranged, rubber (or nylon) plate 3 is set on the inner face of another straight-bar 4.Two straight-bars of described suspension hook U-shaped coupler body 1 are 30-50 ° angle, and opening increases from inside to outside gradually.

During use, be hung in cast tube 5 two ends with two Cast tube hooks 1, rope of each Cast tube hook 1 usefulness is buckled 6 and is passed suspension hook rope connecting bore 2 and connect together, and rope 6 other ends are provided with latch closure, can hang on the crane hook 7.

Claims

1, a kind of Cast tube hook is characterized in that described Cast tube hook is the U-shaped coupler body, in coupler body two straight-bars always the masthead end one rope connecting bore is arranged, rubber (or nylon) plate is set on the inner face of another straight-bar.

2, according to the described Cast tube hook of claim 1, it is characterized in that described suspension hook U-shaped coupler body, two straight-bars are acute angle, and opening increases from inside to outside gradually.
