Technical field
The utility model relates to timber handling machinery field, the particularly special grab bucket of a kind of round log.
Background technology
Grab bucket captures the bucket that silt stone, timber and various bulk freight can open and close, namely be that a kind of folding mainly keeping left right two combination buckets or multiple jaw captures and draws off the suspender of bulk material, grab bucket can be divided into mytiliform to grab bucket and the grab bucket of tangerine lobe according to Shape Classification, the former is made up of two complete scraper bowls, and the latter is made up of the jaw of more than three or three; Fluid pressure type can be divided into grab bucket according to type of drive and mechanical type grab bucket two large classes.
China many years ago, stevedoring log, with 4 ~ 6 workmans in ship storehouse, first wear in the section gap of rollway with little steel rope, surround the area of estimation, two ends of little steel rope are hung on the hook of hoisting crane, lift by crane 1 ~ 2 meter of distance, one end of log is allowed to stick up, then workman takes the steel rope of one 16 ~ 28, steel rope front end also has very heavy hook, from be raised one with the neutral of yard get rid of over, the workman of another side catches fast, otherwise steel rope is ined succession, hook can be slipped in yard groove, get rid of steel rope workman to obtain pull-up steel rope and again get rid of again, or steel rope gets with the instrument long waddy being filled with hook by the workman of another side, then hook is hung to be got up by log bundle on a steel cord, in this process, log may roll, weigh the trick of workman wounded, also likely workman has tied log overload more, steel rope is disconnected aloft, tens or tens logs crash in the air, people can be killed, while there is huge potential safety hazard, the efficiency of logrolling is also very low.Given this, the utility model provides a kind of timber haulage equipment, i.e. the special grab bucket of a kind of round log, round log grab bucket is as the term suggests be exactly the grab bucket being used for loading and unloading log specially, timber grab not only increases production efficiency, it is crucial that separate men from machines during handling timber, and the safety substantially increased.
Utility model content
In order to solve the problem, the utility model provides the special grab bucket of a kind of round log, and it can realize the function of separate men from machines when handling timber, the safety substantially increased; Also greatly improve production efficiency simultaneously.
To achieve these goals, the utility model realizes by the following technical solutions: the special grab bucket of a kind of round log, comprise pawl head, drum bar, the first rotational pin, first connecting rod, the second rotational pin, second connecting rod, the 3rd rotational pin, retaining-plate and lifting hydraulic cylinder, the quantity of described pawl head, drum bar, the first rotational pin, first connecting rod, the second rotational pin, second connecting rod, the 3rd rotational pin and lifting hydraulic cylinder is two; Described drum bar is fixedly mounted on pawl head lateral wall; Described first connecting rod one end is connected with in the middle part of drum bar by the first rotational pin, be connected by the second rotational pin between the first connecting rod other end with second connecting rod one end, and first connecting rod madial wall medium position place is provided with trigonid, second connecting rod madial wall medium position place is provided with Triangulum, upper Triangulum and trigonid are positioned on same vertical centre axis, retaining-plate bottom face is symmetrically arranged with two mounting ear seats respectively along its longitudinal center's axis, adopts the 3rd rotational pin to be connected between the second connecting rod other end and the mounting ear seat of retaining-plate; Described lifting hydraulic cylinder is between the trigonid and the upper Triangulum of second connecting rod of first connecting rod, and lifting hydraulic cylinder two ends all adopt articulated manner to be connected respectively with between the trigonid of first connecting rod and the upper Triangulum of second connecting rod.
As a kind of optimal technical scheme of the present utility model, described pawl head is pressed from both sides by five pawls and cross bar forms, and five pawls are clipped on cross bar and are linearly equidistantly evenly arranged, and pawl folder semicircular in shape shape structure.
As a kind of optimal technical scheme of the present utility model, described drum bar is I-shaped structure, and drum bar two ends are respectively arranged with strengthens round bar joint, is provided with rotating shaft in the middle part of drum bar.
During use, first control lifting hydraulic cylinder and carry out stretching routine, by the stretching routine of lifting hydraulic cylinder drive first connecting rod and second connecting rod all with the second rotational pin for the center of circle is done to the rotation outside two, thus two pawl heads are opened, adopt have five semicircular structures pawl folder can actv. increase round log capture time stability, prevent the slippage during crawl of round log; Then control lifting hydraulic cylinder and carry out contractile motion, by the contractile motion of lifting hydraulic cylinder drive first connecting rod and second connecting rod all with the second rotational pin for the center of circle is done to the rotation inside two, thus two pawl heads are shunk, realize the gripping function to round log.
Compared with prior art, the beneficial effects of the utility model are: a kind of round log Special grabbing bucket feature such as have compact conformation, simple to operate and cost of manufacture low, and it can realize the function of separate men from machines when handling timber, the safety substantially increased; Also greatly improve production efficiency simultaneously.
