Detailed Description
As shown in fig. 1-6, a clump weight lifting appliance comprises a lifting rod 1, wherein a first lifting mechanism 2 is arranged on the left and the right of the lifting rod 1, and a second lifting mechanism 3 is arranged in the middle of the lifting rod 1.
The first lifting mechanism 2 comprises a support frame 4, the support frame 4 is integrally in a shape of a square, the front side face and the rear side face of the support frame are arc-shaped, and the support frame is attached to the inner side wall and the outer side wall of the balancing weight 5 when being sleeved on the balancing weight 5. The outer wall of the support frame 4 is provided with a reinforcing rib, so that the integral support strength can meet the requirement. The upper end of the supporting frame 4 is connected with a lifting rod 6, the lifting rod 6 consists of a lower lifting rod 6-1 and an upper lifting rod 6-2, and the lower lifting rod 6-1 and the upper lifting rod 6-2 are hinged through a pin shaft. The lower lifting rod 6-1 and the upper lifting rod 6-2 can freely pass through holes on the lower bottom plate of the connecting frame 7 and then are threaded with the nut 8, a baffle 6-3 with a notch is also arranged on one side of the lower bottom plate of the connecting frame 7, when the upper lifting rod 6-2 is positioned on the lower bottom plate of the connecting frame 7, the upper lifting rod 6-2 is rotated, and the upper lifting rod 6-2 can just pass through the baffle 6-3 with the notch and is locked by the nut 8.
The lifting rod 6 is sleeved with a compression spring 14, and the compression spring 14 is positioned between the support frame 4 and the connecting frame 7 and is in a compression state. Therefore, the lifting rod 6 can always have a downward pulling force, and the upward movement of the supporting frame 4 when the supporting frame is empty can be avoided.
The upper end of the connecting frame 7 is provided with a slide block 9, and the slide block 9 is arranged on the slide rail of the suspension rod 1 in a sliding way.
The boom 1 here conforms to the curvature of the counterweight 5 and is longer at both ends than the counterweight 5. The center of the suspender 1 is provided with a hanging ring 13, and the hanging ring 13 is used for being hung on a hook of a beam bridge type hook crane.
The second lifting mechanism 3 comprises a belt 10, the lower end of the belt 10 is sleeved on the bulge 11 of the balancing weight 5, the upper end of the belt 10 is sleeved on the grooved wheel 12, and the grooved wheel 12 is installed on the suspension rod 1 through a bearing seat.
The working principle and the process are as follows: when the counterweight 5 needs to be hung, the hanging ring 13 is hung on a hook of a bridge-type hook crane, the left and right first lifting mechanisms 2 slide outwards to two ends of the suspender 1, and the device is moved to the counterweight 5 through the crane. The lower end of the belt 10 is sleeved on the bulge 11, and the balancing weight 5 is lifted. Then, the two first lifting mechanisms 2 are drawn close to the balancing weight 5, the supporting frame 4 is sleeved on the balancing weight 5, the first lifting mechanisms 2 are in a state shown in fig. 5 (a small gap is kept between the lower bottom surface of the balancing weight 5 and the supporting frame 4), the balancing weight 5 is kept balanced through the three parts, and when the lifting device moves, the balancing weight 5 cannot fall off from the lifting appliance to injure people. After moving to the designated position, the left and right first lifting mechanisms 2 are slid outward to the two ends of the suspender 1 again and isolated from the counterweight 5. And simultaneously, the lifting pull rod 6-2 is lifted upwards, and after the lifting pull rod 6-2 passes through the notch of the baffle 6-3, the friction locking is realized through the nut 8. The lower end of the bracket frame 4 is higher than the lower end of the balancing weight 5 because the bracket frame moves upwards along with the rotation of the upper pull rod 6-2 to the transverse position. The beam bridge type hook crane drives the lifting appliance and the balancing weight 5 to slowly move downwards until the balancing weight 5 falls to the ground. And taking down the belt 10 to finish the final hoisting and moving work.
