Problems solved by technology

[0002] The leveling control of the existing rack and pinion lifting equipment is realized by using the method of traction lifting equipment through sensor detection and electrical control friction braking, but due to the performance drift of the detection control components and the change of the friction coefficient of the friction parts The leveling accuracy will change; in fact, according to the characteristics of the rack-and-pinion lifting equipment itself, there can be leveling control measures to maintain the accuracy of the leveling layer more stable; the existing safety braking measures for the rack-an

Example Embodiment

[0023] Example 1, Picture 8 It is a schematic diagram of Example 1. The figure shows the appearance of the side of the lifting equipment. The gear rack lifting equipment electromagnetically pulls the leveling control safety brake device installed on the rack and pinion lifting equipment temporarily in a braking state , Picture 9 It is a schematic diagram of the situation that the lifting equipment equipped with the rack and pinion lifting equipment electromagnetic pulling the leveling control safety brake device in the embodiment 1 is in the brake release state, the lifting equipment is ready to operate or is in operation, (the previous figure shows The left and right mentioned are from the inside of the lifting equipment to the side of the lifting equipment, Picture 8 , Picture 9 It is viewed from the outside to the side of the lifting equipment, so the left and right directions are exactly reversed.) The gear rack lifting equipment electromagnetically pulls the leveling con...

Example Embodiment

[0024] Embodiment 2 is a lifting device equipped with the rack and pinion lifting device of the present invention electromagnetically pulling the leveling control safety brake device, Picture 10 It is a schematic diagram of embodiment 2, which shows the situation when the electromagnetic puller main body 1 is in a power-off state, and the electromagnetic pull leveling control safety brake device performs braking. Picture 11 This is the schematic diagram of the embodiment 2 when the electromagnetic puller main body 1 is in the energized state and the electromagnetic pulling leveling control safety brake device is in the free position state. The electromagnetic pulling leveling control safety brake device used in the rack and pinion lifting device is specific The structure is an independent electromagnetic pulling leveling control safety brake device assembly that is separately set up with independent components and then installed on the lifting equipment. Its structure and workin...

Abstract

The invention relates to a ear rack lifting appliance electromagnetic pulling flat layer control safety braking device. A movable rack can be horizontally moved on a rail assembly or keep at certain positions, the top of the movable rack is in direct contact with a main bearing structure of a lift car of a lifting appliance or is subject to contact bearing through a middle transition bearing component after entering the braking state, and an operation mechanism of the movable rack operates the movable rack to horizontally move on a rail hole or is stopped and kept are certain positions; the certain positions include the braking position and the free position, the braking position is meshed with a lifting equipment driving rack, and the free position is completely separated from the lifting equipment driving rack by a certain gap; and a rack meshed manner is adopted for conducting flat layer control and safety protection braking, the beneficial effects of improving the flat layer accuracy, keeping the precision and safely protecting the braking quality are achieved.

Description

technical field [0001] The invention relates to the field of leveling control and safety braking devices for lifting equipment, in particular to an electromagnetically pulling leveling control safety braking device for rack and pinion lifting equipment. Background technique [0002] The leveling control of the existing rack and pinion lifting equipment is realized by using the method of traction lifting equipment through sensor detection and electrical control friction braking, but due to the performance drift of the detection control components and the change of the friction coefficient of the friction parts The leveling accuracy will change; in fact, according to the characteristics of the rack-and-pinion lifting equipment itself, there can be leveling control measures to maintain the accuracy of the leveling layer more stable; the existing safety braking measures for the rack-and-pinion lifting equipment, or It is realized by braking the motor shaft or by braking the gear...
