Automatic pin penetrating device for lifting hooks of gantry crane

Abstract

The invention discloses an automatic pin penetrating device for lifting hooks of a gantry crane. The automatic pin penetrating device comprises a pin penetrating machine tool seat and a centering seat, wherein the pin penetrating machine tool seat is located on a balance beam at the top of a spillway door, and the centering seat is matched with the lifting hooks of the gantry crane. The automatic pin penetrating device is characterized in that a penetrating pin with straight line guiding mechanisms is arranged in the pin penetrating machine tool seat; a mobile transmission mechanism and a manual transmission mechanism are arranged in a manner of being matched with the penetrating pin; the mobile transmission mechanism comprises a driving device and a friction wheel matched with the penetrating pin; a mechanical locking device is arranged at the head of the penetrating pin; and a wireless receiving controller is arranged in the driving device. Through the adoption of the automatic pin penetrating device disclosed by the invention, the automation of the overall process of pin penetrating between the gantry crane and a grabbing beam is realized; the working at a high place of an operator is avoided, so that the labor intensity is greatly reduced, the safety of the pin penetrating work is guaranteed, the working efficiency is improved, and the spot space is effectively utilized; and the integral structure is simplified, so that the automatic pin penetrating device is convenient to mount, and the developing of the overhauling and maintaining work is facilitated.

Description

technical field [0001] The invention relates to reservoir flood discharge equipment technology, in particular to an automatic pin-pinning device for a gantry crane hook. Background technique [0002] The automatic threading device is widely used in engineering machinery, such as the patent announcement number is CN205187635U, a kind of automatic threading device for high-temperature material tanks, including a driving pulley block, the bottom of the driving pulley block is connected with the main body of the grabbing beam, and the lower end of the main body of the grabbing beam There are two grasping ears welded symmetrically in the face, and the grasping ears and the lifting lugs on the high-temperature material tank are connected by two symmetrically arranged automatic pin-threading devices to form a pin shaft connection. The automatic pin-threading device includes a motor, which is fixedly installed at the lower end of the main body of the grabbing beam On the heat shield...

AI Technical Summary

Problems solved by technology

Since the threading pin is installed on the hook, the weight is heavy, and the hook is in a tilted state when it comes out. The threading work requires the cooperation of multiple workers to lift the threading pin to keep the hook in balance, and at the same time keep the hook in alignment with the balance beam. Only then can the threading operation be carried out, and the threading operation is cumbersome, time-consuming and laborious

Because the pinning operation point is high from the ground, and the edge of the adjacent dam is higher than the crest guardrail, the staff need to climb up to work, and there are great safety hazards

The pinning work of the door crane hook and the balance beam is the first step in the lifting of the spillway door. If it is blocked, it is not conducive to the development of flood control work. Generally, the door cranes at the top of the dam are in the outdoor environment, and encounter severe weather such as strong wind and heavy rain. , it also poses a great threat to the personal safety of climbing workers
