Abstract

The utility model discloses an automatic hooking and unhooking device of a ship lock maintenance gate, and belongs to the technical field of cranes. The automatic hooking and unhooking device of the ship lock maintenance gate mainly comprises hooks, pull rods, rotation arms, balance weight plates and balance weight arms. The hooks are of a specific shape and are connected with the rotation arms through the pull rods. The rotation arms are provided with the balance weight plates. In the automatic hooking process, the hooks collide with and squeeze hook pins of the ship lock gate so that the hooks can rotate around the center points by a certain angle, when the hook pins pass through the highest points of the hook tips of the hooks, the hooks automatically return under the effect of the balance weight plates and self weight, and therefore automatic hooking is achieved. In the automatic unhooking process, the hooks drop continuously, the inner sides of the hooks squeeze the hook pins so that the hooks can rotate around the center points by a certain angle, when the angle is large enough and the balance weight plates also rotate by more than 90 degrees, the balance weight plates rotate and slide down automatically towards another direction, the hooks keep static with the angle under the effect of the balance weight plates, then a hanging beam is lifted, the hooks are separated from the hook pins automatically, and therefore automatic unhooking is achieved.

Description

A kind of ship lock Emergency Gate automatic coupling/decoupling device

Technical field

The utility model relates to the rubber tyre gantry crane design field, relates in particular to a kind of ship lock Emergency Gate automatic coupling/decoupling device.

Background technology

Grasping beam is one of the visual plant in power station, and it cooperates headstock gear to finish the task of lifting by crane and putting down gate.Existing grasping beam major part can not realize automatically taking off hooking process under the unpowered prerequisite, though can realize that by hydraulic pressure or electric power operation automatic hanging breaks off relations, need to carry out waterproof, also needs the traction wireline operation, has certain potential safety hazard; Can realize on a small quantity the mechanically actuated grasping beam of this function in manufacturing and designing, structure is complicated, and difficulty of processing is larger.

The utility model content

Technical problem to be solved in the utility model is: a kind of ship lock Emergency Gate automatic coupling/decoupling device is provided, realizes automatically taking off hooking process under the unpowered prerequisite by simple structure.

The technical solution of the utility model is: a kind of ship lock Emergency Gate automatic coupling/decoupling device, and it comprises: hook, pull bar, pivoted arm, balancing disk and hanger pin; It is characterized in that: described hook links to each other by pull bar with pivoted arm, and the pivoted arm center is equipped with balancing disk.

The profile of described hook rotates when the extruding of itself and gate hanger pin.

Described hook, when automatic coupling, the anglec of rotation of hook can guarantee that the balancing disk anglec of rotation is less than 90 degree under the four-bar mechanism effect; When automatically-unhooked, the anglec of rotation of hook can guarantee that the balancing disk anglec of rotation is greater than 90 degree under the four-bar mechanism effect.

Tie point between described pivoted arm and the balancing disk is designed with the rotation breach.

After having adopted technique scheme, the beneficial effects of the utility model are: do not need waterproof in the process of the utility model realization automatic trip hook, do not need power supply, also do not need manual operation, reduced the danger of work high above the ground; The utility model is simple in structure, and manufacture difficulty is little, is widely used in lifting and puts down water conservancy gate.

Description of drawings

Fig. 1 is structural representation of the present utility model;

The specific embodiment:

As shown in Figure 1, link to each other by pull bar 3 between described hook 1 and the described pivoted arm 5, pivoted arm 5 is furnished with balancing disk 4.

During automatic coupling: hanger pin 2 downthrusts of described hook 1 and lock gate, hook 1 is rotated to an angle around central point, when hanger pin 2 bypassing hooks 1 bill peak, hook 1 automatically resets under the effect of balancing disk 4 and deadweight, realizes automatic coupling;

When automatically-unhooked: described hook 1 continues to fall, hook 1 inboard and hanger pin 2 extruding, hook 1 is rotated to an angle around central point, when angle enough large, when balancing disk 4 also rotate and spends above 90, balancing disk 4 is towards the landing of other direction automatic rotation, hook 1 keeps this angle static under balancing disk 4 effects, at this moment, will carry on the hanging beam, the hook 1 with hanger pin 2 automatic trips from, realize automatically-unhooked.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
