Abstract
Disclosed is a bidirectional chain locking device of a tank truck cleaning machine lifting mechanism. In an existing lifting mechanism, only one chain is provided, a tooth-form central line of an upper chain wheel and a lower chain wheel is a straight line from the top view, a chain locking adjustment is unidirectional, and since the chain is perpendicularly mounted, the chain is easy to loose and the lower chain wheel is easy to separate from the chain after long-term use. The bidirectional chain locking device comprises a locking oil cylinder (1), the upper end of the locking oil cylinder (1) is connected with an upper chain wheel assembly (2) which is connected with an upper chain, the upper chain is connected with a chain fixing connection plate (5) through a connection rod (4), the chain fixing connection plate is connected with a lower chain (6) which is connected with a lower chain wheel assembly, the other end of the lower chain is connected with a movable sliding frame chain connection plate (8) via a connection rod, and the movable sliding frame chain connection plate is connected with the other end of the upper chain. The bidirectional chain locking device is used for the tank truck cleaning machine lifting mechanism.
Description
Technical field:
The utility model relates to a kind of fuel tank washing machine elevator mechanism chain two-way locking device.
Background technique:
Chain is one in the elevator mechanism in the past, and sprocket tooth form center line line plan view is straight line up and down, and it is unidirectional adjusting that chain is locked regulative mode, and owing to the chain at right angle setting, after long-term the use, chain is easily loosening, the easy and chain disengaging of lower sprocket.
Summary of the invention:
The purpose of this utility model provides a kind of chain that makes can bidirectional modulation, solved lower sprocket after the long-term use easily with the fuel tank washing machine elevator mechanism chain two-way locking device of chain disengaging problem.
Above-mentioned purpose realizes by following technological scheme:
A kind of fuel tank washing machine elevator mechanism chain two-way locking device, its composition comprises: locking cylinder, described locking cylinder upper end connects the upper sprocket wheel assembly parts, described upper sprocket wheel assembly parts connects upper chain, described upper chain is connected and fixed chain connecting plate by connecting rod, described fixedly chain connecting plate connects lower chain, described lower chain connects the lower sprocket assembly parts, the described lower chain the other end connects the movable carriage chain connecting plate by connecting rod, and described movable carriage chain connecting plate connects the described upper chain the other end.
Described fuel tank washing machine elevator mechanism chain two-way locking device, described upper chain and described lower chain two ends are separately fixed on 4 holes of described movable carriage chain connecting plate and described fixedly chain connecting plate, and described hole is rectangular.
Beneficial effect:
1. what the utility model adopted is the bidirectional modulation mode, has solved lower sprocket easily and chain disengaging situation.
The chain that the utility model adopts has two-way regulating function, has reached the state that bidirectional-movement does not rupture, do not break away from.
