Description

Portable detachable steel member stone tongs

Technical Field

The utility model belongs to building steel structure portal rigid frame type factory building hoist and mount operation construction field, concretely relates to portable detachable steel member stone tongs is applicable to the hoist and mount in-process among the building site steel construction engineering, can greatly improve hoist and mount efficiency in actual construction, reduces the safety risk of workman's high altitude unhook in-process.

Background

The economy of China keeps stable and rapid development for a long time, the living standard of people is improved, meanwhile, the demands of various substances are also improved, the vigorous development of industrial construction is promoted invisibly, and particularly in the construction of industrial plants, the use degree of the portal steel frame industrial plants is deepened continuously at present. The important components such as the steel structure beams, the columns and the like of the portal steel frame are specially manufactured in a factory and then are transported to a site for hoisting, and the construction progress of the steel structure is in a key line of the project, so that the portal steel frame is very important for safely and smoothly completing the whole project.

According to market investigation, in the whole construction field of the building steel structure, a traditional hoisting mode generally adopts a welding lifting lug or a steel wire rope for binding and hoisting, for the welding lifting lug hoisting mode, the lifting lug welding preparation work in the early stage needs to consume the cost in the aspects of labor, time and materials, the gas cutting removal of the lifting lug in the later stage has the risk of damaging the surface of a component, and a large amount of working hours are consumed for subsequent polishing and paint replenishment; for the steel wire rope binding and hoisting mode, preparation work in the aspects of protection of acute angles of steel members, reasonable binding of the steel wire ropes and the like is required to be done in the early stage, and the consumed time is long. The two hoisting modes simultaneously have safety risks caused by the fact that workers need to ascend from the ground and unhook the hooks. Therefore, there is a need for a lifting tool that can be quickly disassembled and assembled and can avoid high-altitude unhooking to overcome the shortcomings of the existing temporary facilities and technologies.

The utility model discloses a following technical scheme realizes:

the utility model provides a portable detachable steel member stone tongs, includes hoist and mount wire rope, and hoist and mount wire rope top is connected with the crane hook, and hoist and mount wire rope bottom is broken out with two and is connected, and every is broken out and all is articulated with the hoist and mount splint that correspond, and two hoist and mount splint are the splayed setting, and two hoist and mount splint offside are provided with the bayonet socket, and the bayonet socket of two hoist and mount splint blocks the steel member both sides, and two hoist and mount splint all dismantle the stay cord through pull ring and splint and are connected.

The bottom end of the hoisting steel wire rope is provided with the rope ring, and the two shackles are connected with the rope ring.

The bayonet is a chute arranged at the side part of the hoisting clamping plate.

The stiffening plate is arranged outside the bayonet.

Compared with the prior art, the utility model, have following advantage:

1. the utility model discloses the equipment is simple swift, and it is convenient to dismantle, can used repeatedly, has reduced partial process, and the processing preparation is easy, has improved hoist and mount efficiency greatly, has saved construction cost, can break up the whole into parts and be convenient for store the transportation, and easily safety inspection.

2. The safety risk caused by the fact that a traditional hoisting mode needs manual climbing for unhooking is avoided, only manual operation is needed for unhooking on the ground, and safety and reliability are achieved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in figures 1-4, a portable detachable steel member stone tongs, including hoist and mount wire rope 5, hoist and mount wire rope 5 top is connected with crane hook 7, hoist and mount wire rope 5 bottom is connected with two shackles 4, every 4 shackles are all articulated with the splint 3 that correspond, two splint 3 are the splayed setting, two splint 3 opposite sides are provided with bayonet socket 10, the bayonet socket 10 of two splint 3 blocks steel member 9 both sides, two splint 3 all dismantle stay cord 1 with splint through pull ring 2 and are connected.

The bottom end of the hoisting steel wire rope 5 is provided with a rope ring 8, and the two shackles 4 are connected with the rope ring 8.

The bayonet 10 is a chute 11 arranged at the side part of the hoisting clamping plate 3.

A stiffening plate 6 is arranged outside the bayonet 10.

The utility model is suitable for a steel member 9 hoist and mount constructions such as conventional steel construction industry factory building girder steel, steel column, the use as follows:

confirm splint according to steel member 9's shape, size, weight, focus and operation radius etc. and dismantle stay cord 1, shackle 4 and hoisting machinery, the hoisting point is close to steel member 9 structure as far as possible and strengthens the department and avoid the hoisting point to appear the slip condition during the use, and hoist and mount wire rope 5 should not be greater than 60 with the horizontal plane contained angle, should not be less than 45, avoids doing in bad weather operations such as five grades of strong wind days, fog day, rainy day. The steel member 9 can be used when the plate thickness of the flange plates on both sides is less than the width of the bayonet 10 of the lifting clamp plate 3 by more than 2 mm.

Before hoisting, a professional company skilled in the art of support for the certificate carries out strict inspection on the connection condition. During hoisting, at the moment of hoisting stress of the hoisting steel wire rope 5, the hoisting clamping plate 3 simultaneously generates horizontal component force and flange plate direction component force perpendicular to the steel member 9 due to the tension force, so that the bayonet 10 of the hoisting clamping plate 3 is clamped with the flange plate of the steel member 9, the hoisting adopts a slow hoisting, stable hoisting and slow releasing operation mode, the connection condition of each hoisting point is rechecked after the steel member 9 is hoisted to 20cm away from the ground, the steel member 9 is strictly prevented from hovering in the air for a long time, a sway rope connected with the steel member 9 is arranged in advance, and the swing amplitude of the steel member 9 in the air is controlled.

Properly loosen hoist and mount wire rope 5 after steel member 9 high altitude butt joint is fixed, pull splint dismantlement stay cord 1 to the direction opposite with bayonet socket 10 opening through the manual work simultaneously on ground, splint dismantlement stay cord 1 drives hoist and mount splint 3 through pull ring 2 and wholly outwards demolish for thereby bayonet socket 10 breaks away from the flange plate realization quick dismantlement stone tongs of steel member 9. The whole operation process does not need to ascend the height from the ground and unhook the ground manually, is simple and convenient, and greatly reduces the potential safety hazard in the high-altitude operation.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
