Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a safety brake and a lifting system. Background Art

[0002] Automated warehousing systems usually include equipment such as three-dimensional shelves, unmanned transport vehicles, stackers, access systems and control systems. The main equipment of the access system is the elevator, which is used to complete the lifting and lowering of goods and handling robots from the ground to the height of the rail surface of each layer of the shelf, or from the height of the rail surface of each layer of the shelf to the ground, and to change layers between the rail surfaces of each layer of the shelf. During the operation of goods and handling robots entering and exiting the three-dimensional warehouse, a significant increase or decrease in load will cause the deformation of the traction mechanism itself to increase or decrease, and the change in the force direction between the lifting platform and the counterweight will cause the mechanism to rotate slightly in the opposite direction, thereby causing the position of the lifting platform to move, and the leveling accuracy and stability of the equipment cannot be guaranteed.

[0003] At present, in order to prevent the car from falling suddenly when the elevator is under maintenance, the automatic anti-fall system and electric / pneumatic brake mechanism are mainly used. However, although the automatic anti-fall system is a relatively stable device, the equipment cost is high, the mechanical mechanism is very complex, and a large space needs to be reserved before design. Although the electric / pneumatic brake mechanism is relatively simple and compact, it needs to rely on air source and electronic control components, which is difficult to maintain and cannot be maintained when the power is off or the air is off.

[0004] Currently, no effective solution has been proposed for the problems of high equipment cost, complex mechanical structure and inconvenient repair and maintenance in related technologies. Utility Model Content

[0141] Finally, the staff rotates the fine-tuning screw 330 so that the ends of the fine-tuning screw 330 are pressed against the two ends of the engagement member 210 in the length direction, thereby fixing the engagement member 210 and preventing the elevator car from falling.

[0142] The advantage of this embodiment is that by detachably connecting the engaging component and the fine-adjusting component to the frame of the elevator through the sliding component, the engaging component can be moved on the frame of the elevator, thereby making it adaptable to different types of elevators and improving the applicability of the safety brake; by arranging a fine-adjusting component on the sliding component and connecting the fine-adjusting component to the engaging component, the horizontal position and vertical position of the engaging component on the sliding component can be slightly adjusted, thereby improving the convenience and accuracy of the clamping between the engaging component and the rack of the elevator.
