Abstract

The invention discloses a lifting mechanism composed of unidirectional bending transmission chains.The lifting mechanism is characterized in that on the first side of each transmission chain, an inner baffle is fixedly connected between a pair of chain plate bodies of each inner chain plate, and an outer baffle is fixedly connected between a pair of chain plate bodies of each outer chain plate; the two ends of each inner baffle are flush with the axis of pin holes formed in the two ends of the corresponding inner chain plate, and each outer baffle is provided with extension sections at the two ends; the extension sections of the outer baffles form single-side support to the inner baffles, each transmission chain is prevented from being bent towards the first side, and the transmission chain can be unidirectional bent in the direction facing the second side; the first side and the second side of each transmission chain are two sides located at the opposite positions, and two unidirectional bending transmission chains jointly form the lifting mechanisms.The lifting mechanism can be applied in a road block capable of rising and falling and is simple in structure and reliable in function.

Description

[0001] The application number is 2015103419524, the application date is June 18, 2015, the title of the invention is a one-way bending transmission chain and its application, and the applicant is a divisional application of Hefei University of Technology. technical field

[0002] The invention relates to a transmission chain and its application, more specifically to a transmission chain and its application in a lifting mechanism and a roadblock as a road auxiliary facility. Background technique

[0003] The application of transmission chains is quite common, but so far there is no public report about unidirectional bending transmission chains.

[0004] The passing capacity of urban level crossings is an important part of urban traffic. In order to ensure the traffic safety of urban level crossings, in addition to setting up complete traffic signal facilities, it is often accompanied by manual management, which is an important part of manual management. The content of the cro...
