Description

A kind of geosphere formula framing member handling anchor clamps

Technical field

The utility model relates to the handling anchor clamps, and particularly a kind of geosphere formula framing member handling anchor clamps of weldering hanger are made and do not allowed to adorn to high-strength steel.

Background technology

The geosphere formula framing member that major diameter, high strength steel material are made is meant and adopts thickness steel plate big, that yield strength is high, superficial hardness is high to bend that back dress weldering forms.Need the superficial hardness of handling geosphere formula framing member higher, be equal to or higher than the running surface hardness of common handling anchor clamps, the geosphere formula framing member landing of hanging can occur during handling, cause the construction safety accident.

The welding fitness for purpose of high strength steel is higher, for preventing that producing defectives such as crack of weld, pore, slag inclusion damages mother metal, also needs measures such as preheating and after heat when dress weldering hanger.Even take measures, also weld defect may appear, in case measures such as repair welding just need be taked in damage mother metal surface, same position repeatedly repair welding also may cause sheet material to scrap.Moreover hanger also can influence the erection work of other part, also need excise hanger after the handling and carry out grinding process.Moreover, dress weldering hanger on this geosphere formula framing member, not only waste material but also waste time and energy, production efficiency is low.Therefore, generally do not allow arbitrarily dress weldering hanger.

In view of above-mentioned particularity, can not find at home suitable hang, rigging can use for the handling of geosphere formula member.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of handling efficient height, safety, is fit to the geosphere formula framing member handling anchor clamps that the weldering hanger was made and do not allowed to adorn to special high strength steel material.

The technical scheme that adopts is:

A kind of geosphere formula framing member handling anchor clamps comprise hook, following suspension hook, steel rope.Described hook is made up of last elevator, last sleeve pipe, case in and bolt, nut, last elevator is to be assembled and welded together and to be constituted by the stay bearing plate between biside plate and the biside plate, last elevator be equipped with bolt hole up and down, last sleeve pipe and case in, be separately positioned on the two bolt hole positions up and down of elevator, to go up sleeve pipe and case in is contained on the elevator by bolt, nut, constitute hook.Described suspension hook down is by elevator, pulley, axle sleeve, bearing pin are formed down, following elevator is to add frock by steel plate through blanking to be welded into box-structure, following elevator upper end side plate is provided with tapped bore, axle sleeve is contained on the pulley endoporus and uses screw locking, and be arranged on down elevator tapped bore position, bearing pin is installed on to be threaded in the axle sleeve and with the one end and is fixed on down on the elevator, constitutes suspension hook down.One end cover of steel rope hangs on the hook case in, the pulley of suspension hook under the other end pile warp, and sleeve pipe on the pile warp hook again, cover hangs on the crane gib head, constitutes a kind of geosphere formula framing member handling anchor clamps.

The utility model is simple in structure, easy-to-operate, flexibly, practical, save time, need not adorn the weldering hanger during laborsaving, handling, but as the lifting device repeated use, both improved production efficiency, created good economic benefit again.

The specific embodiment

A kind of geosphere formula framing member handling anchor clamps comprise hook 1, following suspension hook 2, steel rope 3.Described hook 1 is made up of last elevator 4, last sleeve pipe 5, case in 6 and bolt 7, nut 8, last elevator 4 is to be assembled and welded together and to be constituted by the stay bearing plate between biside plate and the biside plate 9, last elevator 4 be equipped with bolt hole up and down, last sleeve pipe 5 and case in 6 are separately positioned on the two bolt hole positions up and down of elevator 4, to go up sleeve pipe 5 and case in 6 is contained on the elevator 4 by bolt 7, nut 8, constitute hook 1.Described suspension hook 2 down is by elevator 10, pulley 11, axle sleeve 12, bearing pin 13 are formed down, following elevator 10 is to add frock by steel plate through blanking to be welded into box-structure, following elevator 10 upper end side plates are provided with tapped bore, axle sleeve 12 is contained on pulley 11 endoporus with screw 14 lockings, and be arranged on down elevator 10 tapped bore positions, bearing pin 13 is installed on to be threaded in the axle sleeve 12 and with the one end and is fixed on down on the elevator 10, constitutes suspension hook 2 down.One end cover of steel rope 3 hangs on hook 1 case in 6, the pulley 11 of suspension hook 2 under the other end pile warp, and sleeve pipe 5 on the pile warp hook 1 again, cover hangs on the crane gib head, constitutes a kind of geosphere formula framing member handling anchor clamps.

Principle of work:

As shown in Figure 4, two groups of geosphere formula framing member handling anchor clamps are placed appropriate location, geosphere 15 both sides respectively, the hook 1 of every group of handling anchor clamps is stuck in geosphere 15 upper port, and following suspension hook 2 is stuck in geosphere 15 lower port, and cover hangs over the angle of the steel rope 3 on the crane gib head less than 60 degree when guaranteeing lifting.During handling, along with the crane gib head rises at a slow speed, steel rope 3 tightens up, hook 1 is subjected to downward pulling force, pulley 11 under steel rope 3 pullings on the suspension hook 2 upwards, make hook 1 and following suspension hook 2 tightly embrace geosphere 15, sling and fall at a slow speed again after geosphere 15 makes it to stand up, promptly finish the process of standing up, transport to other position for also capable of hoisting and put down, same, available four pairs of handling anchor clamps lift by crane simultaneously, geosphere formula framing member is steadily lifted, make lifting job safer, easy landing when having avoided other elevator handling and the Peril Incident that takes place.This anchor clamps are not subjected to the influence of surface of steel plate hardness and geosphere formula framing member diameter etc., only consider that the working strength of anchor clamps itself and lift heavy are stressed.Actual uses by a large amount of lifting operations in the product construction prove that this anchor clamps are easy to use, reliable, satisfy the handling requirement fully.
