Description
Technical field
The utility model relates to a kind of forcipated sling, belongs to suspender technical field.
Background technology
Suspender is in elevator machinery, to hang the device of getting weight, and hanging and getting the most frequently used suspender of article is suspension hook, also has suspension ring, hoisting suction cup, clamp and pallet fork etc.; In modern industrial premises, often use a large amount of cylindrical material, due to its smooth surface, while landing without floating ignore, cannot use the suspenders such as suspension hook, suspension ring, hoisting suction cup to carry out handling, need to below cylindrical material, wear lifting rope hanging while getting cylindrical material, this process need repeatedly be found the equilibrium point of lifting, and need to be with article as liner in the time of discharging, can extract lifting rope, therefore use existing suspender to carry out the shipment of cylindrical material or unload have that inefficiency, auxiliary facilities are many, complex operation, dangerous high drawback.
Utility model content
The purpose of this utility model be for solve use existing suspender to carry out the shipment of cylindrical material or unload have that inefficiency, auxiliary facilities are many, complex operation, problem that danger is high, and then provide a kind of forcipated sling of handling cylinder material.
The technical solution of the utility model:
A kind of forcipated sling of handling cylindrical material comprises suspension ring, hoisting bracket, two fixed beams and two suspenders, the center of gravity place of hoisting bracket is provided with suspension ring, hoisting bracket two ends are separately installed with the suspender being symmetrically set, two suspenders link together by two fixed beams, each suspender includes two rhombus four-bar linkages, the drift angle of two rhombus four-bar linkages connects by rotating shaft, each rhombus four-bar linkage includes two connecting rods and two pickup arms, the top of pickup arm is straight-arm, bottom is circular arc arm, between two circular arc arms, form jaw, the lower end of two straight-arms connects by rotating shaft, the upper end of two straight-arms is connected by rotating shaft with the lower end of a connecting rod respectively, the upper end of two connecting rods connects by rotating shaft.
Preferred: between former and later two circular arc arms of described each rhombus four-bar linkage, to be provided with back-up block.So arrange, can ensure the crawl intensity of suspender in handling cylindrical material process, avoid cylindrical material landing to cause danger.
Preferred: described each suspender also comprises hook, hook is arranged between rotating shaft topmost and rotating shaft bottom.So arrange, in the time of withdraw from use suspender, hook is hooked in the rotating shaft being locked in bottom, can smoothly cylindrical material be placed on to assigned address, and suspender is removed.
The utlity model has following beneficial effect: the utility model is from hanging the material of getting, analyze the required feature of drawing materials of hanging, use four-bar linkage, by cylindrical material effective location in suspender, that this forcipated sling has is simple in structure, low cost of manufacture, easy to operate feature, solve and used existing suspender to carry out the shipment of cylindrical material or unload the loaded down with trivial details work that process existence is repeatedly found lifting equilibrium point and worn lifting rope, improved work efficiency, reduced auxiliary facilities, reduced handling danger.
