Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and specifically relates to a hoisting device for civil engineering construction. Background Art
[0002] In the current technical field of building construction, hoisting devices undoubtedly play a crucial auxiliary role. However, traditional hoisting devices have significant deficiencies in design. When these devices hoist heavy objects, the stability of the hook connection is poor, which greatly increases the safety risks during the operation process. At the same time, due to the lack of an effective shock absorption and buffering mechanism, when placing the lifted items, the items are easily damaged due to impact and vibration. More critically, when it is necessary to take out the internal materials from the lifted items, the existing hoisting devices are often cumbersome to operate, which greatly affects the work efficiency.

The lower end of the lifting plate is hinged to one end of the support rod. The other end of the support rod is hinged to the moving block. A first chute is provided at the bottom end inside the housing. The moving block is threadedly connected to the rotating rod and is limited to slide in the first chute. One end of the rotating rod is fixedly connected to the output shaft of the motor. The motor is fixed on the housing.

The two buffer mechanisms are symmetrically arranged. Moving mechanisms are fixed to both ends of the housing. The two moving mechanisms are symmetrically arranged.
[0006] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0007] 1. Stability and safety: The device is equipped with two buffer mechanisms, effectively ensuring the stability and safety during the hoisting and lowering processes.

[0009] 3. Accuracy of material transfer: Through the lifting function of the lifting plate, this device can precisely control the height of the material, ensuring that the material can be accurately placed or taken out. In addition, the fastening unit in the connecting mechanism can tightly hold the hook, preventing the material from slipping during the lifting process and ensuring the accuracy of material transfer.
[0010] 4. Flexibility and applicability: This lifting device is applicable to a variety of civil engineering construction scenarios. The design of the walking wheels and cylinders enables the device to adapt to different terrains and working environments, with strong flexibility and applicability.

The two buffer units are arranged in pairs, and each buffer unit is fixedly connected to the lower end of the housing 1.
[0023] Each of the buffer units includes a fixed block 13, a sliding rod 14, a compression spring 15, a slider 16 and a connecting rod 17;
[0024] The upper end of the fixed block 13 is fixedly connected to the lower end of the housing 1. A second chute is provided at the lower end of the fixed block 13. The sliding rod 14 is horizontally fixed in the second chute. The slider 16 is limited and slidably arranged in the second chute and is slidably connected to the sliding rod 14.

[0029] When using the present utility model, first confirm that the hoisting device is in the initial state, the walking wheels 10 are on the ground, and the air cylinders 8 and the motor 6 are not started; then, hook the hoisting hook to the fixing frame 18, ensure that the hook is between the two fastening units, and rotate the threaded rod 20 to tightly clamp the hook by the fastening plate 21 and the fixing plate 19.

At this time, the buffer plate 11 leaves the bottom surface; then start the motor 6, the motor 6 drives the rotating rod 7 to rotate, so that the moving block 5 moves along the rotating rod 7. As the moving block 5 moves, through the action of the support rod 4, the lifting plate 3 is lifted to separate the material from the bottom surface, facilitating the staff to take out the material from the hoisting device. After the material is taken out, start the motor 6 again to lower the lifting plate 3 to the initial position, ready for the next hoisting operation or evacuating the site.
