Description

Technical Field

[0001] The utility model relates to the technical field of bent cap steel bar skeletons, and particularly relates to a hoisting device for an integral bent cap steel bar skeleton. Background Art

[0002] A bent cap steel bar skeleton is formed by combining multiple steel bars into a complete grid structure, and is a cross beam arranged at the top of a row of pile piers to support, distribute and transfer the loads of the upper structure. Its main function is to support the upper structure of the bridge and transfer all loads to the lower structure. Generally, after the bent cap steel bar skeleton is welded on the ground, it is hoisted onto the bent cap formwork. Therefore, a hoisting device for an integral bent cap steel bar skeleton needs to be set up to hoist the bent cap steel bar skeleton. However, the existing devices still have certain defects in use, such as:

[0003] A hoisting tool for a bent cap steel bar skeleton disclosed in the patent No. "CN202320275474.1" has multiple uniformly distributed hoisting points for the steel bar skeleton. When hoisting the bent cap steel bar skeleton, it can ensure uniform overall stress during hoisting and reduce the deformation of the steel bars caused by hoisting. However, when the device is in use, the traditional hoisting device directly winds multiple lifting ropes around the steel bars. When one of the lifting ropes is not fully fixed, it will fall off, resulting in an offset of the stress during hoisting of the steel bars, and leading to unsafe factors such as the inclination of the steel bar skeleton. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting device for an integral bent cap steel bar skeleton to solve the above problems, and to improve the problem of unsafe factors such as inclination during hoisting of the existing hoisting device for an integral bent cap steel bar skeleton.

[0005] A hoisting device for an integral bent cap steel bar skeleton includes a hoisting shell, a connecting column, a steel wire rope and a connecting plate: a connecting column is arranged at the lower end of the hoisting shell, a steel wire rope is arranged at the lower end of the connecting column, a connecting plate is arranged below the steel wire rope, the connecting column is slidably connected with the hoisting shell, and a lifting rope fixing structure is arranged at the upper end of the connecting plate;

[0006] The lifting rope fixing structure includes a fixing block, a limiting block and a fixing bolt. A fixing block is arranged at the lower end of the steel wire rope, a limiting block is arranged at the upper end of the connecting plate, and a fixing bolt is arranged on the side of the limiting block.

[0007] Preferably, the fixing bolt penetrates through the limiting block, the fixing bolt is threadedly connected with the fixing block, and a lifting ring is arranged at the upper end of the hoisting shell.

[0008] Preferably, a support plate is arranged inside the lifting shell. The support plate is connected to the connecting column. A support spring is arranged at the lower end of the support plate. The support plate is slidably connected to the lifting shell. A friction block is arranged on the side surface of the support plate.

[0009] Preferably, a trigger button is arranged at the inner bottom end of the lifting shell. Two buzzers are arranged on the side surface of the lifting shell in alignment. A storage battery is arranged on the side surface of the lifting shell.

[0010] Preferably, a fixing plate is arranged at the upper end of the connecting plate. A limit bolt is arranged on the side surface of the fixing plate. The limit bolt penetrates through the fixing plate. A nut is arranged on the surface of the limit bolt. The nut is threadedly connected to the limit bolt.

[0011] Preferably, a mounting block is arranged on the surface of the limit bolt. The limit bolt penetrates through the mounting block. A lifting rope is arranged at the lower end of the mounting block.

[0012] Preferably, a protective shell is arranged at the upper end of the connecting plate. An alarm is arranged at the upper end of the protective shell.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. Through the settings of the reset spring, sliding ring, trigger and alarm, when the device is in use, first put the lifting rope on the steel bar, and then start lifting. At this time, the weight of the steel bar skeleton pulls the lifting rope downward, so that the lifting rope pulls the sliding ring downward and compresses the reset spring. Then, when the steel bar skeleton is slowly lifted, if one of the lifting ropes that is not fully fixed cannot bear the weight and falls off, at this time, the resilience of the reset spring jacks up the sliding ring, so that the sliding ring touches the trigger and presses the trigger, causing the alarm to emit a sharp sound, reminding the staff that the lifting rope is not fixed properly and stopping the lifting in time to re-fix the lifting rope, preventing the lack of stress points after lifting and resulting in unsafe problems such as the inclination of the steel bar skeleton, and can timely remind the staff to stay away and avoid in time.

A support spring 12 is provided at the lower end of the support plate 10. The support plate 10 is slidably connected to the lifting shell 1, and a friction block is provided on the side of the support plate 10;

[0029] When the device is in use, during lifting, the steel wire rope 2 moves downward, pulling the connecting column 11 downward, causing the connecting column 11 to drive the support plate 10 downward. At this time, the support spring 12 enables the support plate 10 to move downward stably, and the friction blocks on both sides of the support plate 10 are used to achieve a damping effect, so that the support spring 12 provides a buffering effect.

[0030] A trigger button 13 is provided at the inner bottom end of the lifting shell 1. Two buzzers 9 are provided on the side of the lifting shell 1 in alignment, and a storage battery 8 is provided on the side of the lifting shell 1;
