Problems solved by technology

The advantage of the long strut grab is that the grabbing force and digging force are large at the beginning of closing, but the disadvantage is that the closing force tends to weaken when the jaw plate of the grabbing bucket is close to closing
The scissor grab has more advantages than the long pole grab, mainly because the grabbing and closing force tends to increase with the progress of the closing movement of the grab, but its disadvantage is that the grabbing force and digging force are small at the beginning of closing, Based on consumption

Embodiment Construction

[0021] Such as Figure 1 to 4 Shown is a schematic structural diagram of a short strut grab bucket according to an embodiment of the present invention. It consists of two opening and closing ropes 1, two supporting ropes 2, a supporting rope frame 3, two rope pulleys 4, and two upper struts 5. , A middle beam 6, two strut pulley groups 7, two lower strut rods 8, two bucket jaws 9, a middle beam pulley group 10, a middle beam guide wheel group 11 and two connecting devices 12. The supporting rope 2 is connected to the supporting rope frame 3, the opening and closing rope 1 is wound on the center beam pulley block 10 through the rope pulley group 4, and the supporting rope frame 3 and the connecting device 12 arranged on the upper strut 5 are hinged to point F, The center beam guide wheel group 11 is arranged on the center beam 6. In addition, the upper strut 5 and the center beam 6 are hinged at point A, the upper strut 5 and the lower strut 8 are hinged at point B, the lower strut ...

Abstract

The invention is about a short brace grab bucket which includes the start-stop rope, the supporting rope, the supporting rope frame, the block rope wheel group, the bucket jaw plate, the centre sill hinged with the jaw plate and the two connected devices. The centre sill pulley block is set in the hinged point of the centre sill which is installed the centre sill guide wheel group. The up end of the left-right up supporting bars is hinged to the centre sill and the down end is connected to the left-right down supporting bars. The invention can change the grab ability by changing the times of the group pulley block, so it has the high grab ability but simple structure and long life.

Description

Technical field [0001] The invention relates to a lifting machinery grabbing device, in particular to a short strut type grab bucket. Background technique [0002] Grabs have been used in bulk material handling and industrial production for more than one hundred years. Today, they are mainly divided into two categories: long strut grabs and scissor grabs. [0003] Currently widely used are mainly long strut grabs and scissor grabs on large crane loading and unloading machinery. [0004] Both types of grabs have their own advantages and disadvantages. The advantage of the long strut type grab bucket is that the grabbing force and digging force are large when it starts to close, but the disadvantage is that the closing force tends to weaken when the grab body jaws are close to closing. The scissor grab has more advantages than the long strut grab. The main reason is that as the closing movement of the grab progresses, the grasping and closing force tends to increase, but its disadv...
