Problems solved by technology

[0005] There are many types of roadblocks in the prior art, including translational, rotary, and hydraulic types, etc., translational and rotary roadblocks take up too much space for originally narrow intersections, and the roadblocks are slow in place, prolonging the Passing time; hydraulic roadblocks need to build hydraulic stations and oil pipes, which also occupy a large space, frequent installation and maintenance, and high cost

Embodiment Construction

[0035] see Figure 1a , Figure 1b and Figure 1c In this embodiment, the one-way bending transmission chain is formed by connecting the inner chain plate 31 and the outer chain plate 32 through the pin shaft 33 in the pin hole, and the roller 34 is set on the pin shaft 33, and the inner chain plate 31 And outer chain plate 32 are a pair of chain plates.

[0036] On the first side of the transmission chain, the inner baffle plate 31a is fixedly connected between a pair of chain plates of the inner chain plate 31, and the outer baffle plate 32a is fixedly connected between a pair of chain plates of the outer chain plate 32; Both ends of the inner baffle 31a are aligned with the axial positions of the pin holes at both ends of the inner chain plate 31, and the outer baffle 32a has extensions at both ends.

[0037] see Figure 2a , Figure 2b and Figure 2c , in this embodiment, the extension section of the outer baffle 32a forms a one-sided support for the inner baffle 31a,...

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...
