Abstract
The utility model relates to a parallel claw-typed straw hoisting grab bucket for hoisting. The claws of the parallel claw-typed lifting grab bucket are connected with plate-spring-typed elastic claw ends by bolts. The utility model which is suitable for hoisting materials with irregular tightness reduces the grab leakage phenomenon caused by uneven tightness of claw grab.
Description
The utility model relates to a kind of lifting and grabs bucket with parallel pawl formula forage lifting.
The material pawl end of existing parallel pawl formula lifting grab bucket is a rigidity, and lifting forage during the irregular material of degrees of tightness such as linen-cotton, because the pawl of each parallel material pawl point material grasping gap is consistent, leaks pawl at soft place easily.
The purpose of this utility model provides a kind of not leakiness forage lifting grab bucket of grabbing of the irregular material of degree of tightness that is suitable for lifting.
The technical solution of the utility model is the elastic claw end of bolt together laminated spring type on each material pawl of parallel pawl formula lifting grab bucket.
Because the pawl end of the utility model material pawl is elastomeric, when grasping the irregular material of degree of tightness, when working than the material pawl of many places, material firmly grasps in advance and produces elastic deformation, the material pawl at the less place of material continues promptly material of motion, and relatively phenomenon is grabbed in the leakage that significantly reduced when grasping the irregular material of degree of tightness of the parallel material pawl of rigidity.
Fig. 1 of accompanying drawing is the utility model structural scheme of mechanism, and Fig. 2 is a multilayer elastic material pawl structural scheme of mechanism, Fig. 3 be the K of Fig. 1 to scheme drawing, Fig. 4 is the structural scheme of mechanism that has the hydraulic pressure grasping mechanism.
Forage lifting grab bucket shown in Figure 1, the material pawl 1 that is installed on the hinge 5 is arranged, material pawl 1 is the two opposite groups material pawl of a plurality of uniform arrangement in parallels of axis along hinge 5, two groups of material pawls 1 are connected with switch connecting rod 2 switch frames 3 by hinge respectively, draw at the center that has tie-rod 4 to pass switch frame 3 on the hinge 5, and the end of material pawl 1 of the present utility model is connected with laminated spring type elastic claw end 6 by bolt 7.The shape of elastic claw end 6 as shown in Figure 3.
The elastic claw end 6 of above-mentioned grab bucket can also be made the bar spring type elastic claw end of circular section.
Between the hinge 5 of above-mentioned grab bucket and the switch frame 3 hydraulic ram 8 can be installed as shown in Figure 4, an end of oil cylinder 8 is connected with hinge 5, and the other end is connected with switch frame 3.Switch frame 3 is connected with the pulley or the steel cable of lifting crane.
