Detailed Description
The principle of the invention is that a guide groove 7 is arranged at the lower right side of a push plate 6, the push plate 6 is controlled to stretch through a hydraulic cylinder 2, the locking and unlocking of a sinking chain 10 are realized, and meanwhile, in the process, the guide groove 7 at the lower right side of the push plate 6 plays a role in guiding, so that the mechanism is prevented from deviating. And, set up the third hinge 8 in the joint of catch plate 9 and push pedal 6, support the catch plate 9 and can be turned over upwards, protect the whole mechanism.
The invention comprises the following steps: hydraulic cylinder 2, push plate 6, third hinge 8 and cardboard 9.
The following is further illustrated by examples and figures.
Example (b): as shown in the attached drawing 1, the whole mechanism is driven by hydraulic pressure, the push plate 6 is connected with the hydraulic cylinder 2 through the second hinge shaft 5, and the locking and unlocking of the sinking chain 10 are realized by utilizing the extension and contraction of the push plate 6. The rear part of the clamping plate 9 is provided with a slot-shaped bayonet. The slot-shaped bayonet can be clamped on the chain 10 in a sinking state when being extended out. The clamping plate 9 is connected with the push plate 6 through the third hinge shaft 8, the clamping plate 9 can be overturned upwards for a certain distance to absorb the influence on the whole mechanism caused by the locking and unlocking of the sinking chain 10, and the whole mechanism is protected to a certain extent. A piston rod at the rear side 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 twisting shaft 1. The integral mechanism is arranged on a throwing boat through a first hinge shaft 1 connected with a hydraulic cylinder 2, and the first hinge shaft 1 is mainly used for fixing the hydraulic cylinder 2.
In the foregoing, the lower left of the hydraulic cylinder 2 is connected with the oil inlet pipe 3, and the lower right is connected with the oil outlet pipe 4.
In the foregoing, when the hydraulic cylinder 2 pushes the push plate 6 out through the second hinge shaft 5, the front edge of the push plate 6 rotates around the third hinge shaft 8, and the clamping plate 9 is pulled to clamp and lock the chain 10, so as to prevent the chain 10 from sinking; on the contrary, under the drive of the hydraulic cylinder 2, after the push plate 6 is retracted, the clamping plate 9 is pulled reversely to unlock, and the chain 10 can be continuously sunk.
In the foregoing, the right lower side of the push plate 6 is provided with the guide groove 7, which plays a role of limiting and guiding, standardizes the moving posture and the moving limit of the push plate 6, and prevents the mechanism from deviating. When the mechanism works, the cutting sleeve of the guide groove 7 is arranged outside the corresponding guide post fixing structure on the throwing boat.
In this embodiment, cardboard 9 is connected through third hank axle 8 with push pedal 6, and cardboard 9 only can upwards overturn, in case the condition that chain 10 upwards surpassed and draw appears, cardboard 9 can be along with chain 10 upwards upset certain distance, prevents that chain 10 from surpassing to draw and form the destruction effect and directly conduct push pedal 6, causes the whole board of push pedal 6 to be stretched out, plays certain guard action to whole mechanism.
In this embodiment, the front side and the rear side 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 a larger degree of freedom, and meanwhile, the clamping sleeve guide post of the guide groove 7 provides guiding limit, so that the flexible, stable and accurate clamping 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.
The specific implementation steps are as follows.
During stone throwing construction, in the process of sinking the chain 10, after the chain 10 reaches a certain depth, if locking is needed, the hydraulic cylinder 1 is started to push the push plate 6, the guide groove 7 on the lower right side of the push plate 6 is clamped with an external guide post, the whole push plate 6 moves forwards along the guide post, and after the clamping plate 9 clamps the chain 10, the chain 10 is locked; if the unlocking is needed, the push plate 6 is retracted by the hydraulic cylinder 1.
The invention is verified by practical engineering experiments, the application effect is better, the safety factor is higher, and the technical effect and the popularization and application value of the technical scheme are outstanding.
The above examples are intended to assist the reader in understanding the present invention, and are not intended to limit the present invention in any way, and any modifications or equivalent changes and modifications which do not depart from the spirit of the present invention may be included within the scope of the present invention.
