Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

As shown in fig. 1 to 4, the reinforcing steel bar hoisting and clamping device for building engineering comprises a connector 1, wherein a hoisting connection hole 2 is formed in the center of the top of the connector 1 and is used for connecting a steel wire rope of a hoisting device. Both sides are a pair of drum 3 of symmetry installation in the connector 1, drum 3 is connected with connector 1 bearing, install torsional spring 4 between drum 3 and the connector 1, make the drum can keep the state of tightening up. And one side of each wire coil 3 is provided with a locking device 5 which can lock the wire coil to prevent the wire coil from rotating. The wire coil 3 is wound with a hoisting wire 6 which is a non-elastic wire, one end of the hoisting wire 6, which is far away from the wire coil 3, is connected with a binding barrel 7, and the binding barrel is sleeved at two ends of a bundle of reinforcing steel bars and used for fastening the reinforcing steel bars. This device carries on spacingly through a constraint section of thick bamboo to the reinforcing bar both ends, makes the reinforcing bar can not take place the skew at hoist and mount in-process, and wherein the limiting displacement of a reinforcing bar constraint section of thick bamboo can guarantee that the reinforcing bar does not loose and tie, has in time taken place to loose bundle the phenomenon at hoist and mount in-process reinforcing bar, and a constraint section of thick bamboo also can tie the reinforcing bar firmly together to avoid the reinforcing bar to drop and lead to the fact the injury to the staff on the bottom surface. The bottom of the connector 1 is welded with a cross beam 8, and the bottom of the cross beam 8 is provided with a plurality of clamping jaws 9 in linear installation. The jack catch mainly snatchs fixedly to the middle part of reinforcing bar, through the cooperation of a plurality of jack catches, makes the hoist and mount process of reinforcing bar more firm.

Specifically, dead axle 11 has all been welded to both sides in the connector 1, drum 3 is connected with dead axle 11 bearing promptly, torsional spring 4 is installed between drum 3 and dead axle 11. When the binding barrel is required to bind the two ends of the reinforcing steel bar, the binding barrel is pulled to enable the hoisting line to be scattered out of the wire coil, and the wire coil rotates along with the hoisting line, so that the torsional spring converts kinetic energy into elastic potential energy to be stored. When the binding barrel is sleeved at the end parts of the reinforcing steel bars at the two ends, the locking device can be started to retract the wire coil, so that the hoisting wire is tightened to finish the binding effect on the reinforcing steel bars. Locking device 5 includes electro-magnet 51, power 52, remote switch 53 and sliding shaft 54, sliding shaft 54 is fixed in connector 1 inner wire coil 3 one side through the welded mode, the fix with screw slip shell 55 on the electro-magnet 51 lateral wall, slip shell 55 and sliding shaft 54 sliding connection, wire coil 3 is fixed through countersunk head bolt and is adsorbed limit 56 with electro-magnet 51 matched with ferromagnetism towards locking device 5 one side, remote switch 53 and the equal bolt fastening of power 52 are in the connector 1 outside, power 52, remote switch 53 and electro-magnet 51 establish ties. When the device needs to lock the wire coil, the remote controller only needs to send an instruction through the remote control switch, the remote control switch conducts current, the electromagnet can be powered on to generate magnetism, so that attraction is generated on the ferromagnetic adsorption edge, the sliding shell slides along the sliding shaft under the attraction of the magnetic force, the electromagnet is fixed with the wire coil, and under the limiting action of the sliding shaft, the wire coil cannot drive the electromagnet to be active, so that the locking effect of the locking device on the wire coil is realized. When the hoisting is completed and the reinforcing steel bar needs to be loosened, the remote control switch is disconnected through the remote controller, and after the binding barrel is taken down at the two ends of the reinforcing steel bar, the wire coil rotates under the action of the torsion spring to wind the hoisting rope on the wire coil.

Specifically, the jaw 9 includes a left jaw 91 and a right jaw 92, the top of the left jaw 91 is pivoted with the top of the right jaw 92, and the pivoted position is connected to the bottom of the cross beam through a steel wire rope. The articulated connecting rod 93 in left side claw 91 bottom, right side claw 92 bottom integrated into one piece connector link 94, connecting rod 93 is used for fixed left claw 91 and right claw 92 with connector link 94 joint. After the left claw and the right claw surround the left side and the right side of the steel bar, the connecting rod is penetrated from the bottom of the steel bar to enable the connecting rod hasp to be buckled, a closed structure is formed, and the steel bar is supported. The gravity of reinforcing bar is mainly born jointly by a plurality of jack catchs, and the axial effort of reinforcing bar is mainly born by the constraint section of thick bamboo at both ends.

Specifically, the jack catch 9 comprises a hoisting hook and a hoisting belt, the hoisting hook is welded on the bottom surface of the cross beam, and the hoisting belt is hung on the hoisting hook. Through the constraint effect of the hoisting belt, the reinforcing steel bars can be bundled up, and the supporting and hoisting of the reinforcing steel bars are realized.

Specifically, the hoisting line 6 is a steel wire rope. The steel wire rope has good flexibility on the premise of ensuring the strength, and can meet the hoisting requirement of the steel bar.

Specifically, the constraint cylinder 7 is a cylindrical structure with one open end, the connecting lug 71 is welded on the side wall of the open end, the end of the hoisting wire is connected with a fastening bolt, and the connecting lug 71 is connected with the hoisting wire 6 through the fastening bolt. The connecting lug at the front end of the binding barrel can keep the binding barrel in a vertical state in a loose state, so that the binding barrel is easier to store.

The bottom of the cross beam of the device is linearly provided with 4 clamping jaws, and the use of the clamping jaws can be reduced as appropriate according to the amount of the steel bars.
