AI Technical Summary
When the existing water conservancy project template lifting device encounters sudden changes in wind or lifting speed, the template is prone to large shaking, resulting in fatigue and breakage of the hook bolt and formwork fall accidents, and lacks an effective three-dimensional limit structure.
The sliding mechanism and anti-swing assembly are adopted. The sliding mechanism forms a vertical guide rail through the slide rod and the slider, and the C-shaped fixing member forms a rigid fixation with the connecting member through the threaded rod. The V-shaped anti-bias pulley of the anti-swing assembly limits the lateral displacement of the wire rope, realizing the rigid fixation of the template and the track limit.
Effectively suppress the violent shaking of the template during lifting, avoid the template falling and the hook breaking, and ensure the stability and safety of the lifting process.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of template lifting, and more specifically, to a template lifting device. Background Art
[0002] Water conservancy projects are constructed to eliminate flood hazards and develop and utilize water resources. Based on the objects they serve, they are categorized into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and coastal reclamation projects. During the construction of dams and dikes in water conservancy projects, various construction formworks need to be transported. For convenience, corresponding formwork lifting devices are generally used to lift the formworks.
[0003] However, in practice, existing formwork lifting systems for hydraulic projects often utilize a single hook suspension system. This can cause the formwork to sway significantly when subjected to sudden changes in wind speed or lifting speed. For example, during construction of a reservoir dam, the formwork swung by a hook-type lifting system at force 6 winds, potentially exceeding 15°. This caused fatigue fracture of the hook bolts due to repeated alternating stress, resulting in the formwork falling. The core flaw lies in the lack of a three-dimensional retaining structure for the formwork, relying solely on flexible steel wire rope suspension, which fails to effectively suppress sway under dynamic loads.

[0037] Working principle of the present invention: When the present invention is in use, first pull out the inserting strip 26, then unscrew the threaded rod 21, then clamp both sides of the template into the through groove 23, then reset the inserting strip 26, then put the connecting piece 20 into the C-shaped fixing piece 19, and then fix the connecting piece 20 and the C-shaped fixing piece 19 through the threaded rod 21, then start the stepping motor 8, the stepping motor 8 drives the rotating shaft 7 to rotate through the reducer, the rotating shaft 7 drives the winding roller 10 to retract the wire rope 11, so that the wire rope 11 slides on the anti-deviation pulley 16, the wire rope 11 pulls the connecting block 27 upward, so that the connecting block 27 drives the rectangular block 22 to move upward together through the auxiliary steel cable 28, the rectangular block 22 drives the C-shaped fixing piece 19 to move together through the connecting piece 20, and the C-shaped fixing piece 1 9 drives the slider 18 to move on the slide bar 17, and finally lifts the template upward.

The rubber ring 25 can prevent the insert 26 from sliding off automatically, and at the same time can fix the template more firmly, avoiding the phenomenon of the template swinging during the lifting process. It solves the problem that when there is a strong wind around, the lifted template is prone to violent shaking during lifting, causing the template to fall or the hook to break due to shaking. When the external wind force causes the template to have a shaking tendency, the sliding resistance of the slider 18 on the slide bar 17 can offset part of the shaking energy. At the same time, the sliding on both sides forms a symmetrical limit to constrain the swing amplitude of the template. The insert 26 cooperates with the through groove 23 to form a rigid connection, replacing the flexible suspension of the traditional hook, and eliminating the freedom of the template to swing from a structural perspective.
