The invention discloses a safety alarm system for a bracket mechanism of car lifting jacks. The bracket mechanism comprises a bracket. The bracket comprises two side plates and a supporting mechanism, wherein the two side plates are arranged in a direct-facing mode in parallel, and the supporting mechanism is used for being connected with the side plates. A work nut is provided with cylindrical supporting lugs. The side plates are provided with supporting lug sleeves used for installing the supporting lugs, and the inner holes of the supporting lug sleeves are strip holes formed in the vertical direction. The safety alarm system comprises a PLC system used for controlling the bracket mechanism of the car lifting jacks to ascend or descend. The output end of the PLC system is connected with an alarm device, and the input end of the PLC system is connected with a first microswitch. The first microswitch is installed below the strip holes of the supporting lug sleeves, and a button of the first microswitch faces the strip holes and extends into the strip holes. The safety alarm system has the advantages of being simple in structure, easy to realize, capable of detecting the condition that the bracket mechanism gets stuck and giving an alarm in advance, capable of preventing danger caused by damage of the bracket mechanism, capable of improving the safety of the car lifting jacks, accurate and reliable in detection and the like.
Description
technical field [0001] The invention relates to the technical field of cranes, in particular to a safety alarm system for a bracket mechanism of the cranes. Background technique [0002] With the rapid development of cities, traditional highway traffic has become extremely congested, making it difficult to meet people's commuting and travel requirements. Rail transit has been vigorously developed due to the advantages of large carrying capacity at one time, many operating shifts, and no congestion in collective regulation. [0003] In order to ensure the safety of rail traffic, after the rail vehicle has been running for a period of time, it is necessary to repair or replace the wheelset in the bogie and other components on the bottom of the vehicle. During maintenance, the entire train of vehicles needs to be lifted to a certain height to replace the bottom of the vehicle. Bogies and other components. [0004] When overhauling, it is necessary to lift the carriage from th...
