Description

double-T-beam self-balancing hoisting sling

Technical Field

The utility model belongs to the technical field of hoist and mount hoist, concretely relates to two T roof beams self-balancing hoist and mount hoist.

Background

At present, in the prefabrication operation of the double-T beam prefabricated part, workers arrange reinforcing steel bars in a double-T beam mould and inject concrete into the double-T beam mould, and the double-T beam is formed after the concrete is solidified. In order to facilitate the double-T beam to be separated from the double-T beam mold, the threaded pipes are usually pre-embedded in the double-T beam. When the double T-beam is taken out from the double T-beam mould, a worker often beats the peripheral side of the double T-beam mould first to enable the peripheral side wall of the double T-beam to be separated from the inner wall of the double T-beam mould; meanwhile, a lifting ring is connected to the threaded pipe in a threaded manner; and then, pulling the lifting ring by the travelling crane through the hoisting device to pull out the double T-shaped beam from the double T-shaped beam mould. In the process, the problem of unstable hoisting exists, the hoisting cannot be guaranteed, and finally, the middle of the top plate is induced to have quality damage such as cracks due to unilateral stress.

Disclosure of Invention

The utility model provides a two T roof beams self-balancing hoist and mount hoist has solved the unstable problem of two T roof beams hoist and mount, has guaranteed the quality of two T roof beams.

The technical scheme of the utility model is that: the utility model provides a two T roof beams self-balancing hoist and mount, includes the hoist girder, lifts by crane wire rope, lug, hangs wire rope, hoist girder level sets up and is the rectangle, the both ends of hoist girder are equipped with the top pulley, it is connected with the driving couple through the bottom of top pulley to lift by crane wire rope, the both sides of top pulley are equipped with the steel suspender, the bottom of steel suspender is connected with the bottom pulley, it is connected with the lug through the top of bottom pulley to hang wire rope, the pre-buried top that sets up at the roof of two T roof beams of lug.

Preferably, the bottom of steel suspender is equipped with the hole, be equipped with round pin axle I in the hole, realize being connected with the rotation of lower pulley through round pin axle I.

Preferably, the upper pulley is rotatably connected with the main beam of the lifting appliance through a pin shaft II.

Preferably, the bottom of hanging wire rope is equipped with U type snap ring, U type snap ring bottom is equipped with fixing bolt, U type snap ring card is established on the lug, realizes connecting fixedly through fixing bolt.

Preferably, the lifting lug is of an arc-shaped structure.

The utility model has the advantages that: the utility model discloses at lifting device in-process of getting up with the hook, lift by crane wire rope and hang wire rope and can follow the rotation automatic adjustment wire rope's of top sheave and bottom sheave both sides length according to the different gestures of two T roof beams, make two T roof beams can keep the level, avoid bringing out quality damage such as crackle appearing in the middle part of the roof because of unilateral atress, when realizing that two T roof beams stably lift by crane, guaranteed the quality of two T roof beams.

Drawings

Fig. 1 is a front view of the double T-beam self-balancing lifting tool of the present invention;

fig. 2 is a left side view of the structure of the double T-beam self-balancing lifting sling of the present invention;

wherein: 1. the lifting device comprises a lifting steel wire rope, 2, a lifting device main beam, 3, an upper pulley, 4, a steel lifting belt, 5, a lower pulley, 6, a hanging steel wire rope, 7, a lifting lug, 8, a top plate, 9, a web plate, 10, a U-shaped clamping ring, 11, pin shafts I and 12 and a pin shaft II.

Detailed Description

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which a person skilled in the art can, without any creative effort, fully implement the present invention.

Referring to fig. 1-2, a double-T beam self-balancing hoisting tool comprises a hoisting main beam 2, a hoisting steel wire rope 1, a lifting lug 7 with an arc structure and a hanging steel wire rope 6, wherein the hoisting main beam 2 is horizontally arranged in a rectangular shape, two ends of the hoisting main beam 2 are provided with upper pulleys 3, the upper pulleys 3 are rotatably connected with the hoisting main beam 1 through pin shafts II 12, the hoisting steel wire rope 1 is connected with a crane hook through the bottom of the upper pulleys 3, two sides of the upper pulleys 3 are provided with steel slings 4 which are also connected with the upper pulleys 3 through pin shafts II 12, the bottom of the steel slings 4 is connected with a lower pulley 5, the bottom of the steel slings 4 is provided with a hole, a pin shaft I11 is arranged in the hole and is rotatably connected with the lower pulley 5 through a pin shaft I11, the hanging steel wire rope 6 is connected with the lifting lug 7 through the top of the lower pulley 5, the bottom of the hanging steel wire rope 6 is provided with a U-shaped snap ring 10, u type snap ring 10 bottom is equipped with fixing bolt, U type snap ring 10 card is established on lug 7, realizes connecting fixedly through fixing bolt, 7 pre-buried settings of lug are equipped with four at least at the top of the roof 8 of two T roof beams, guarantee the level of the process of lifting by crane to avoid two T web 9 to lead to the damage because the atress is uneven or the unilateral atress leads to lifting by crane the in-process.
