A special grab bucket for logs

Abstract

The invention relates to a special log grab bucket, which comprises a claw head, an I-shaped rod, a first rotating pin, a first connecting rod, a second rotating pin, a second connecting rod, a third rotating pin, a support plate and a liftable hydraulic cylinder, wherein the I-shaped rod is fixedly arranged on the outer side wall of the claw head, the first connecting rod is connected with the middle of the I-shaped rod through the first rotating pin; the other end of the first connecting rod is connected with one end of the second connecting rod through a second rotating pin; the other end of the second connecting rod is connected with the mounting lug holder of the support plate through a third rotating pin; the liftable hydraulic cylinder is arranged between the lower triangular holder of the first connecting rod and the upper triangular holder of the second connecting rod; the two ends of the liftable cylinder are hinged with the lower triangular holder of the first connecting rod and the upper triangular holder of the second connecting rod. According to the special log grab bucket, the human-machine separation function can be realized during log loading, unloading and transferring, the safety performance is greatly improved and the work efficiency is extremely improved.

Description

technical field [0001] The invention relates to the field of wood handling machinery, in particular to a special grab bucket for logs. Background technique [0002] The grab bucket is a bucket that can be opened and closed by grabbing sand, stones, wood and various bulk goods. Spreaders and grabs can be divided into shell-shaped grabs and orange-shaped grabs according to their shapes. The former is composed of two complete buckets, and the latter is composed of three or more jaw plates; according to the driving mode, it can be divided into It is divided into two categories: hydraulic grab and mechanical grab. [0003] Many years ago in China, when logs were loaded and unloaded at the wharf, 4 to 6 workers were used in the ship warehouse. First, small steel wire ropes were used to pass through the gaps in the section of the log pile to form an estimated area, and the two ends of the small steel wire ropes were hung on the crane. On the hook, lift a distance of 1 to 2 meters...

Problems solved by technology

[0003] Many years ago in China, when logs were loaded and unloaded at the wharf, 4 to 6 workers were used in the ship warehouse. First, small steel wire ropes were used to pass through the gaps in the section of the log pile to form an estimated area, and the two ends of the small steel wire ropes were hung on the crane. On the hook, lift a distance of 1 to 2 meters, let one end of the log tilt up, and then the worker takes a 16-28 steel wire rope with a heavy hook at the front end, and throws it through the gap between the lifted end and the wood pile. The worker on the other side catches it quickly, otherwise the wire rope will slide down into the groove of the wood pile with the hook attached, and the worker who swings the wire rope has to pull up the wire rope and swing it again, or the worker on the other side uses a tool with a hook on a long stick to pick up the wire rope. Get up, and then hang the hook on the wire rope to tie up the logs. In the process, the logs may roll and crush the hands and feet of the workers. It is also possible that the workers bundled too many logs and overloaded, and the wire rope broke in the air. A dozen or dozens of logs Logs falling into the air will kill people. While there is a huge safety hazard, the efficiency of wood handling is also very low.
