Abstract
The invention discloses a crane safety device. The crane safety device comprises a support fixed on a crane crab frame, wherein a safety hook is hinged on the support, one end of the safety hook is provided with a clump weight, and the other end of the safety hook is provided with a hook body; the support is connected with a base in match with the safety hook, two ends of the base are provided with elastic components, the position, which is close to the hook body, between the safety hook and the crab frame, is connected with a pusher, one end of the pusher is connected with the crab frame, and the other end of the pusher is connected with the bottom of the main body of the safety hook, the hook body is provided with an impact block, the crab frame at one side of the hook body is provided with a lifting stop-limiting switch and a lifting over-limiting switch; a hook-throwing limiting switch is arranged between one end of the safety hook provided with the clump weight and the crab frame. The crane safety device disclosed by the invention is not only stable and reliable in operation, but also high in safety coefficient and long in service life.
Description
Technical field
The present invention relates to a kind of hoisting crane, relate in particular to the safety device that the anti-dolly of a kind of hoisting crane topples.
Background technology
Hook with safety tong is the vitals of hoisting crane, claims the damping hook again.The purpose that hook with safety tong is set is the single girder hoisting crane that guarantees in girder one side off the hook, can not tumble when dolly overhauls.This is because single girder crane loading weight is to carry out in a side of girder, and weight etc. produce a tilting moment to dolly, and the anti-tilting moment that is produced by vertical anti-rail wheel or the anti-rail wheel of level makes dolly keep balance, can not tumble.But, only by this mode can't guarantee at disaster caused by a windstorm, accidental shock, wheel is damaged and safety during maintenance.The purpose that the damping hook is set prevents that exactly this class accident from taking place, and guarantees the hoisting crane essential safety.The hook with safety tong ubiquity operation stability of existing hoisting crane is poor, the shortcoming that safety factor is low.
Summary of the invention
The object of the present invention is to provide a kind of crane safety device, it has stable and reliable operation and the high characteristics of safety factor, to solve the problem that hoisting crane exists in the prior art.
For reaching this purpose, the present invention by the following technical solutions:
A kind of crane safety device, it comprises the bearing that is fixed on the monkey frame, be hinged with hook with safety tong on the described bearing, one end of described hook with safety tong is equipped with clump weight, the other end is installed coupler body, and cooperate hook with safety tong to be connected with base on the described bearing, the two ends of described base are provided with elastomeric element, be connected pusher near on the position of coupler body between described hook with safety tong and the trolley frame, one end of described pusher is connected on the trolley frame, the other end is connected in the bottom of hook with safety tong body, described coupler body is provided with collision block, and install to rise on the trolley frame of described coupler body one side and stop limitting switch and the rising switch that transfinites, arrange on the described hook with safety tong between an end of clump weight and the trolley frame hook throwing limit switch is set.
Described elastomeric element comprises the backing plate that is arranged at the base two ends, and described backing plate is provided with elastomer block.The end of described coupler body is provided with the hook limit switch.Described hook with safety tong is articulated on the bearing by axle, and is provided with bearing between described hook with safety tong and the axle.
Beneficial effect of the present invention is a plurality of limit switches compared with prior art to be set between the hook with safety tong of described crane safety device and the trolley frame, and to be provided with elastomeric element, not only stable and reliable operation in base; And the safety factor height, long service life.
