1-first winch shaft, 2-hydraulic cylinder, 3-oil inlet pipe, 4-oil outlet pipe, 5-second winch shaft, 6-push plate, 7-guide slot, 8-third winch shaft, 9-clamping plate and 10-chain.
Detailed Description
The principle of the invention is that the guide groove 7 is arranged at the right lower side of the push plate 6, the push plate 6 is controlled to stretch and retract through the hydraulic cylinder 2, so that the sinking chain 10 is locked and unlocked, and meanwhile, the guide groove 7 at the right lower side of the push plate 6 plays a guiding role in the process, so that the mechanism is prevented from shifting. And a third hinge shaft 8 is arranged at the joint of the clamping plate 9 and the push plate 6, so that the clamping plate 9 can be supported to be turned upwards, and the whole mechanism is protected.
The invention comprises the following steps: the hydraulic cylinder 2, the push plate 6, the third winch shaft 8 and the clamping plate 9.
Further description will be given below by way of examples and accompanying drawings.
Examples: as shown in fig. 1, the whole mechanism is driven by hydraulic pressure, a push plate 6 is connected with a hydraulic cylinder 2 through a second winch shaft 5, and locking and unlocking of a sinking chain 10 are realized by means of expansion and contraction of the push plate 6. The rear part of the clamping plate 9 is provided with a groove-shaped bayonet. The slot-shaped bayonet can be clamped on the chain 10 in a sinking state in an extending state. The clamping plate 9 is connected with the push plate 6 through the third hinge shaft 8, and the clamping plate 9 can be turned upwards for a certain distance to absorb the influence of the sinking chain 10 on the whole mechanism due to locking and unlocking, so that the whole mechanism is protected to a certain extent. The rear piston rod of the hydraulic cylinder 2 is connected with a push plate 6 through a second hinge shaft 5.
In the foregoing, the front end of the hydraulic cylinder 2 is provided with the first winch shaft 1. The whole mechanism is arranged on a throwing ship through a first winch shaft 1 connected with a hydraulic cylinder 2, and the first winch shaft 1 is mainly used for fixing the hydraulic cylinder 2.
In the foregoing, the lower left side of the hydraulic cylinder 2 is connected to the oil inlet pipe 3, and the lower right side is connected to the oil outlet pipe 4.
In the foregoing, when the hydraulic cylinder 2 pushes out the push plate 6 through the second winch shaft 5, the front edge of the push plate 6 rotates around the third winch shaft 8, and the clamping plate 9 is pulled to lock the chain 10, so as to prevent the chain 10 from sinking; conversely, under the drive of the hydraulic cylinder 2, after the push plate 6 is retracted, the reverse traction clamping plate 9 is unlocked, so that the chain 10 can be continuously sunk.
In the foregoing, the lower right side of the push plate 6 is provided with a guide groove 7, which plays a role in limiting and guiding, standardizes the moving posture and limit of the push plate 6, and prevents the mechanism from shifting. When the mechanism works, the guide groove 7 is sleeved outside the corresponding guide post fixing structure on the throwing ship.
In this embodiment, cardboard 9 is connected through third reel 8 with push pedal 6, and cardboard 9 only can upwards overturn, in case the circumstances that chain 10 upwards exceeds the pull, cardboard 9 can upwards overturn a certain distance along with chain 10, prevents that chain 10 from exceeding the pull and forming the direct conduction of destructive action to push pedal 6, causes push pedal 6 monoblock board to be stretched out, plays certain guard action to whole mechanism.
In this embodiment, the front and rear sides of the push plate 6 are hinged by the second hinge shaft 5 and the third hinge shaft 8 to form a transmission mechanism with larger degree of freedom, and meanwhile, the guide groove 7 is provided with a clamping sleeve guide post to provide guiding limit, so that the flexible, stable and accurate clamping connection and the balance of locking strength of the groove-shaped bayonet at the rear part of the clamping plate 9 are realized in the movement of the push plate 6 and the clamping plate 9.
