Description

Clamp type lifting appliance device special for travelling wheel Technical Field The invention relates to the technical field of hoisting and transporting equipment, in particular to a special jaw type lifting appliance device for a travelling wheel. Background In the field of industrial production and logistics transportation, a travelling crane is used as important lifting and transporting equipment, is widely applied to heavy object lifting operation in places such as workshops and warehouses, and in the travelling wheel production process of the travelling crane, a travelling wheel lifting mode of the travelling wheel is generally adopted in the industry in a manner that a steel wire rope penetrates through a small hole of the travelling wheel, and the travelling wheel lifting mode meets basic lifting requirements in a certain period by virtue of the characteristics of simple operation principle, easy acquisition of required tools and the like. However, with the continuous improvement of the requirements of industrial production on the working efficiency, the safety and the service life of equipment, the defects of the traditional lifting mode are increasingly remarkable, and the traditional lifting mode gradually becomes a bottleneck for limiting the working quality and the safety. Firstly, the problem of broken wires is easily caused by the right-angle hoisting of the steel wire rope. In the lifting process, the steel wire rope needs to bear the weight of the travelling wheel in a right-angle state, the stress mode can lead to local stress concentration of the steel wire rope, and repeated bending and friction are extremely easy to lead to abrasion and fuzzing of the steel wire, so that the phenomenon of wire breakage is caused. The damage of wire rope not only can reduce its bearing capacity, shortens life, increases equipment maintenance cost, still probably breaks suddenly at handling in-process, causes serious incident such as heavy object fall, and secondly, the travelling wheel aperture is usually small in size, and operating personnel need spend a large amount of time and energy with wire rope accurate passing aperture, seriously influences operating efficiency. Therefore, the invention provides a special jaw type lifting appliance device for a travelling wheel. Disclosure of Invention The object of the present invention is to solve at least one technical problem set forth in the background art. The invention provides a special jaw type lifting appliance device for a travelling wheel, which comprises a main body frame, a first lifting connecting piece, a second lifting connecting piece, a clamping mechanism and a locking mechanism, wherein the main body frame comprises a first metal arm, a second metal arm, a third metal arm, a fourth metal arm and a pin shaft, through holes for the pin shaft to pass through are formed in two ends of the first metal arm and the second metal arm, through holes for the pin shaft to pass through are formed in one end and a hinged position of the third metal arm and the fourth metal arm, the first lifting connecting piece is fixedly arranged at the upper end of the first metal arm, lifting holes for hanging a lifting hook are formed in the surface of the first lifting connecting piece, the clamping mechanism comprises a lifting ring fixedly arranged at the lower end of the third metal arm and the lower end of the fourth metal arm respectively, and the locking mechanism comprises a positioning ring fixedly arranged on the second metal arm and a hook hinged on the lifting ring. Through adopting above-mentioned technical scheme, the through-hole that aligns first metal arm and second metal arm upper end, penetrate the round pin axle and fix, form rotatable upper portion hinge structure, then cross third metal arm and fourth metal arm, make its articulated position corresponding through-hole align, penetrate the round pin axle fixed, afterwards, the through-hole that aligns first metal arm and second metal arm lower extreme and third metal arm and fourth metal arm upper end, penetrate the round pin axle fixed, four metal arms are connected each other through the round pin axle at this moment, form the articulated frame structure of four arms that can link, and when setting up the hook of locking mechanism in the locating ring, the couple can restrict third metal arm and fourth metal arm and rotate around the round pin axle, can make two gripper arms keep away from each other, at this moment two gripper arms are in the open state, when needing to hoist the travelling wheel, at this moment through external force drive (like the action of lifting equipment), can make third metal arm and fourth metal arm draw in around the round pin axle, the gripper jaw of driving the lower extreme inwards draws in, rely on the gripper jaw and travelling wheel with the travelling wheel of travelling wheel, thereby can realize to the gripping force between the travelling wheel.
