Description

Hook system of double-tail-car stacker-reclaimer

Technical Field

The invention belongs to the technical field of bulk material conveying, and particularly relates to a hook system of a stacker-reclaimer of a double-tail vehicle.

Background

At present, the stacker-reclaimer is widely applied to the industries of coal, grain, building materials, chemical industry, electric power, metallurgy and the like at home and abroad to carry out material conveying operation. When the double-tail-car stacker-reclaimer piles, the auxiliary tail car luffing mechanism is in a material piling state under the action of the oil cylinder, and if the oil cylinder fails, the thrust disappears, and the auxiliary tail car falls down under the action of gravity. However, for the stacking of the existing double-tail vehicle stacker-reclaimer, no protective measures are taken for the hidden danger, and the hidden danger exists. In order to completely avoid potential safety hazards caused by failure of an oil cylinder when the stacker-reclaimer piles materials, a safety protection device of a hook mechanism is designed.

In view of the foregoing, it is desirable to provide a hook system that can improve the safety of the stacker-reclaimer in the stacking state.

Disclosure of Invention

The invention aims to provide a hook system capable of improving the safety of a stacker-reclaimer in a stacking state.

The above purpose is realized by the following technical scheme: the utility model provides a two tail car stacker-reclaimer couple systems, couple system sets up the couple device on the girder of main tail car including the symmetry at least, the couple device is including couple mechanism and push rod mechanism, couple mechanism includes mount pad and couple, push rod mechanism includes frame and telescopic link, mount pad and frame are fixed on the girder, the couple includes the connecting rod and sets up the coupler body of connecting rod one end, the connecting rod middle part with the mount pad is articulated, the one end of telescopic link with the frame is articulated, the other end with the connecting rod is kept away from the one end of coupler body is articulated, the telescopic link can drive the connecting rod and rotate along its hinge point with the mount pad.

When the auxiliary tail vehicle becomes amplitude to the position of a stacking state when the stacker-reclaimer stacks materials, the auxiliary tail vehicle amplitude changing mechanism becomes amplitude to be in place, the push rod is controlled to act, the hook is put down to hook the auxiliary tail vehicle amplitude changing mechanism, the auxiliary tail vehicle is fixed, the mechanical limiting effect is achieved, the purpose of fixing the auxiliary tail vehicle is achieved, and potential safety hazards caused by failure of the oil cylinder are avoided.

Preferably, the further technical scheme is as follows: the telescopic link is the electricity liquid push rod, the couple system still includes the control unit, the control unit with electricity is connected to electricity liquid push rod. The electro-hydraulic push rod works stably and moves sensitively, the control unit controls the extension or the shortening of the electro-hydraulic push rod, the hook can automatically ascend and descend, the amplitude changing mechanism of the auxiliary tail vehicle is fixed and released, the hook mechanism has the advantages of being convenient to operate, efficient and rapid, the productivity of the stacker-reclaimer equipment cannot be influenced, and meanwhile, the control system can be networked with the whole central control system, so that the positioning is accurate, and the control is convenient.

Preferably, the further technical scheme is as follows: the mounting seat and the base are connected with a main beam of the main tail car through bolts. Therefore, the stress of the device is guaranteed, and the device is convenient to maintain.
