Abstract

The invention discloses a rectangular workpiece hoisting tool. Gripping arms are hinged in fork-shaped lifting lugs at the two ends of cross beams through gripping arm hinge pins. A piston rod of a hydraulic cylinder and a cylinder body are hinged at one end of the gripping arm at the upper end of the cross beam respectively by hydraulic cylinder hinge pins; and the two lifting lugs are identical and are symmetrically mounted and fixed on the center line of the upper planes of the cross beams at the two sides of the hydraulic cylinder. The opening and closing operations of the gripping arms do not depend on self weight and hoisting power, and are in a synchronous state; and thus, the rectangular workpiece hoisting tool can work effectively and reliably and can effectively ensure the hoisting safety.

Description

A kind of oblong workpiece lifting tool
Technical field
The present invention relates to a kind of lifting tool, particularly a kind of oblong workpiece lifting tool belongs to the weight-hauling equipment technical field.
Background technology
At the harbour, harbour, building site, factory and other place, often want rectangular-shaped object to load and unload.At present, being used for the lifting tool that load and unload rectangular-shaped object in above-mentioned place, is to utilize lever principle basically on structure and principle, and the arm of force of lever is rotated under the effect of lifting self gravitation, realize the switching of the both sides anchor fluke of lifting tool, thereby realize loading and unloading goods.The grab bucket of this principle and structure can't realize control according to specific circumstances owing to realize the action that opens and closes, in the course of the work, often be subjected to Effect of Environmental, the part of grabbing, knock off can not carry out reliably, there is certain potential safety hazard, occurs safety misadventure easily.
Summary of the invention
The objective of the invention is to: a kind of oblong workpiece lifting tool is provided, this oblong workpiece lifting tool is when work, do not rely on the gravity of self lifting, can overcome existing oblong workpiece lifting tool better, in the course of the work, often be subjected to Effect of Environmental, the part of grabbing, knock off can not carry out reliably, there is certain potential safety hazard, occurs the defective of safety misadventure easily.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of oblong workpiece lifting tool, it is by gripping arm, the gripping arm bearing pin, the hydraulic actuating cylinder bearing pin, crossbeam, hanger, hydraulic actuating cylinder is formed, it is characterized in that: described gripping arm is by two identical forming, gripping arm the pin of an end oriented one side bending, the two ends of described crossbeam produce the ear of fork-shaped symmetrically, described gripping arm is hinged on by the gripping arm bearing pin in the ear of two ends fork-shaped of crossbeam, the piston rod of described hydraulic actuating cylinder and cylinder body are hinged on an end of crossbeam upper end gripping arm respectively with the hydraulic actuating cylinder bearing pin, described hanger is by two identical constituting, and hanger is fixed on the crossbeam of hydraulic actuating cylinder both sides on the plane centreline symmetrically.
Principle of work of the present invention is: the piston rod of hydraulic actuating cylinder is when elongation, promotion is in the gripping arm on crossbeam top and rotates to both sides around the gripping arm bearing pin, the gripping arm that is in the crossbeam bottom is inwardly rotated around the gripping arm bearing pin, so, the anchor of gripping arm is grabbed the direction of trend grabbing workpiece, and when piston rod was regained, above-mentioned action was just in time opposite.
Beneficial effect: a kind of oblong workpiece lifting tool of the present invention, the switching of its gripping arm do not rely on and conduct oneself with dignity and the strength that hoists, and open and close and be in synchronous regime, so, can realize effectively, work reliably, guarantee the safety of lifting effectively.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is the birds-eye view of Fig. 1;
Shown in the figure: 1, gripping arm; , 2 gripping arm bearing pins; 3, hydraulic actuating cylinder bearing pin; 4, crossbeam; 5, hanger; 6, hydraulic actuating cylinder.
The specific embodiment
Gripping arm (1) is hinged on by gripping arm bearing pin (2) in the ear of two ends fork-shaped of crossbeam (4), the piston rod of hydraulic actuating cylinder (6) and cylinder body are hinged on an end of crossbeam (4) upper end gripping arm (1) respectively with hydraulic actuating cylinder bearing pin (3), described hanger (5) is by two identical constituting, and the crossbeam (4) that two hangers (5) is fixed on with claiming hydraulic actuating cylinder (6) both sides is gone up on the plane centreline.
