[0002] The car safety clamp is an important safety protection device for elevators. This protection device is basically installed at the bottom of the car. When the car goes down at an excessive speed or the suspension device breaks, it can clamp the guide rail to keep the car stopped, thereby ensuring the safety of passengers in the car and avoiding equipment damage.

[0003] During the use of the elevator, the safety clamp will occasionally move due to various reasons. After the movement, it needs to be completely reset before the elevator can continue to operate. However, if the safety clamp has design and manufacturing defects, improper adjustment by the installation and maintenance personnel, heavy load and rapid descent, foreign objects falling into the moving parts causing poor movement, etc., after the movement, the staff needs to enter the elevator shaft and maintain the safety clamp.

[0041] When the height of the platform body 4 needs to be adjusted, first, remove the bolts fixing the stabilizing column 8 and the limiting sleeve 801, and then start the first hydraulic cylinder 2, so that the first hydraulic cylinder 2 pushes the connecting frame 202 up and down through the L-shaped plate 201, so that the connecting frame 202 drives the horizontal driving assembly and the platform body 4 to move. During the process, the limiting sleeve 801 will also move with it, and the platform body 4 will also drive the stabilizing block 703 to move on the support rod 702. After adjustment, the limiting sleeve 801 and the stabilizing column 8 can be re-fixed with bolts.

[0042] When the front and rear position of the platform body 4 needs to be adjusted, it is only necessary to start the second hydraulic cylinder 3 so that the second hydraulic cylinder 3 pushes the platform body 4 to move. During the process, the T-shaped slider 701 is driven to slide in the T-shaped slide rail 7 through the stabilizing block 703 and the support rod 702, thereby realizing the front and rear position adjustment.
