Description

A safety brake and lifting system Technical Field

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

[0002] Automated warehousing systems typically include equipment such as three-dimensional racks, unmanned transport vehicles, stackers, access systems, and control systems. The main equipment in the access system is the elevator, which is used to lift goods and handling robots from the ground to the height of the rail surface of each shelf layer, or lower them from the height of the rail surface of each shelf layer to the ground, as well as to switch layers between the rail surfaces of each shelf layer. 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, resulting in the position of the lifting platform to move, and the leveling accuracy and stability of the equipment cannot be guaranteed.

[0003] Currently, to prevent the elevator car from suddenly falling during maintenance, two devices are primarily used: automatic anti-fall systems and electric / pneumatic brake mechanisms. However, while the automatic anti-fall system is relatively reliable, it is expensive and the mechanism is complex, requiring a large space reserve before design. While the electric / pneumatic brake mechanism is relatively simple and compact, it relies on an air supply and electronic control components, making maintenance difficult and requiring repairs during power outages.

[0004] Currently, no effective solutions have been proposed to address the problems of high equipment cost, complex mechanical structure, and inconvenient repair and maintenance in related technologies.

[0140] Subsequently, the staff rotates the fine-tuning screw 330 to allow the meshing member 210 to move vertically on the fine-tuning bracket 120 so that the teeth of the meshing member 210 correspond to the teeth of the rack on the hoist.

[0141] Then, the staff pushes the fine-tuning connecting rod 310 to allow the engaging member 210 to move horizontally on the fine-tuning bracket 120, thereby making the engaging member 210 and the rack of the hoist press against each other.

[0142] Finally, the staff rotates the fine-tuning screw 330 so that the ends of the fine-tuning screw 330 are pressed against both ends of the engagement member 210 in the length direction, thereby fixing the engagement member 210 and preventing the elevator car from falling.

[0143] The advantage of this embodiment is that by detachably connecting the engaging part and the fine-adjusting part to the frame of the elevator through the sliding part, the engaging part 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 the fine-adjusting part on the sliding part and connecting the fine-adjusting part with the engaging part, the horizontal position and vertical position of the engaging part on the sliding part can be slightly adjusted, thereby improving the convenience and accuracy of the clamping of the engaging part and the rack of the elevator.
