Problems solved by technology

But the structure of existing anti-falling and anti-falling devices is very complicated, and the stability is poor. Some devices also need a sufficiently large height difference or when the speed of descent reaches the set value of the device, the device will start, which cannot reflect the safety mechanism. All-around protection
There are also some safety devices that need to be used in conjunction with the electrical system. If there is a problem with the electrical system due to a power outage or system failure, the safety device may fail, posing a major safety hazard.

Embodiment Construction

[0016] as attached Figures 1 to 3 The shown semi-automatic mechanical locking mechanism includes a guide rail 1 and a lift table 2 slidably mounted on the guide rail 1. The lift table 2 is hinged with a lock hook 3, and the guide rail 1 is provided with a lock bar corresponding to the lock hook 3. 4. One end of the lock hook 3 is provided with a hook portion 31 which can protrude from the lifting platform 2 to hook on the lock bar 4 . Under the control of the operator, the lock hook 3 can extend out of the lift table 2 to hook on the lock bar 4 , and of course it can also be completely retracted into the lift table 2 without contacting the lock bar 4 . The lock bar 4 is a cylinder, the hook portion 31 is in the shape of a sharp angle, and an acute angle is formed between one side of the hook and the body of the lock hook 3 for hooking the lock bar 4, and the other side is an inclined surface, When the lifting platform 2 is raised, the locking bar 4 of the cylinder can automa...

Abstract

The invention discloses a semi-automatic mechanical locking mechanism, which belongs to the technical field of mechanical equipment. It includes a guide rail and a lift platform slidingly installed on the guide rail. A lock hook is hinged inside the lift platform. A lock bar corresponding to the lock hook is provided on the guide rail. One end of the lock hook is provided with a protruding lift platform to hook on the lock bar. The hook-shaped part of the lifting platform is hinged with a stop plate used to limit the movement of the lock hook; the stop plate is provided with a card position, and the lock hook is provided with a card corresponding to the card position. Compared with the existing devices, the safety device of the present invention has simpler structure, lower manufacturing cost, convenient operation, more humanization and higher safety performance.

Description

technical field [0001] The invention relates to a semi-automatic mechanical locking structure, which belongs to the technical field of mechanical equipment, and can be used for operation platforms such as lifting hoists and vertical lifting platforms that require vertical or climbing mechanisms. Background technique [0002] In order to protect the personnel on the lifting equipment, the existing lifting machinery, such as elevators, vertical lifts, etc. are generally equipped with anti-fall safety devices, safety gears and other anti-fall and anti-fall devices, and are used together with electrical equipment to provide power to carry personnel and materials. However, the existing anti-fall and anti-fall devices have very complex structures and poor stability. Some devices also require a sufficiently large height difference or the speed of falling to reach the set value of the device before the device can be activated, which cannot reflect the safety mechanism. Some compreh...
