Description

A kind of multi-purpose machinery pawl

Technical field

The present invention relates to bar material handling apparatus technical field, particularly one and be applicable to matching used timber unit clamp on excavating machine.

Background technology

The machine that mostly is that the timber handling of goods yard and cutting area capture the relevant weight-lifting equipment outfit used in operation is grabbed bucket, but the timber in the timber ship loading and unloading of harbour is based on 3 ~ 6 meters of specifications, ship bar, in flank, timber is not in door machine grab bucket operating range, manual work can only be adopted, namely use after manually first one end of round log being started, timber is bundled with other ropes of steel rope and other bindings, and then with hoisting crane or other hanging device, round log is sling, decline after moving to correct position, put down, lay down timber and also must manually unclamp steel rope or rope, by many people compounding practice in whole hoisting process, separate men from machines difficulty is large, easily cause the accident and personal casualty, load and unload the timber process efficiency that wastes time and energy low simultaneously, labor intensity is large.

In addition, the special timber grab of use is also had to carry out round log handling.Described timber grab comprises vehicle frame, the steering device be arranged on vehicle frame, the supporting mechanism being arranged on vehicle frame front portion, the crane arm be arranged on bracing or strutting arrangement, be connected to the oil cylinder between crane arm and bracing or strutting arrangement and be connected to the gripper mechanism of crane arm one end.Existing machinery pawl mechanism comprises two claws that can relatively fasten, middle without connecting device, is closed, is opened, realize crawl and the clamping operation of timber by the hydraulic oil cylinder driving claw be arranged between two claws.There is following defect in this kind of timber grab: 1. timber grab special computer for special use, and running cost is high; 2. two oil cylinder design, an oil cylinder connects crane arm and bracing or strutting arrangement, and for lifting, another oil cylinder is between two claws, and for crawl and the clamping of timber, structure is more complicated, and control also more loaded down with trivial details, maintenance amount is large; 3. along with tonnage increases gradually, the distance between two claws is also in continuous increase, and the mode that this kind utilizes oil cylinder to control claw opening and closing makes when capturing tiny timber operation, and operating efficiency is lower, and easily spreading, operation bad adaptability; 4. two cylinder structure work is inharmonious then greatly stressed between two claws, fragile, causes working stability and poor reliability.

Summary of the invention

Technical assignment of the present invention is for above the deficiencies in the prior art, provides a kind of and is applicable to the excavating machine timber of yard craft operation or the multi-purpose machinery grippers of bar material.

a kind of multi-purpose machinery pawlthe technical scheme solving its technical matters is: a kind of multi-purpose machinery pawl is formed primarily of front pincers tooth, forceps major tooth, connecting panel, pipe link, described pipe link comprises front rod and rear connecting rod, and there is the pin-and-hole structure that can be connected with mechanical arm described connecting panel upper end; Described connecting panel lower-end front portion is connected with front pincers tooth top rotating shaft, and described connecting panel lower-end rear portion is connected with the top rotating shaft of forceps major tooth; Described rear connecting rod two ends connect with front pincers tooth upper end and the upper end rotating shaft of forceps major tooth respectively; Described front pincers tooth lateral surface is connected with coupling end, and this coupling end is connected with the rotating shaft of front rod lower end; The described front rod other end has the pin-and-hole structure that can be connected with the oil cylinder rod shaft of mechanical arm.

a kind of multi-purpose machinery pawl also has following feature:1. before, the inner surface of pincers tooth and forceps major tooth divides anti-slip veins; Front pincers tooth and forceps major tooth have staggered corresponding arrangement front latch and rear latch, front pincers tooth have 2 pieces of latches, forceps major tooth has 3 pieces of latches.

after taking technique scheme, a kind of multi-purpose machinery pawlcan realize: 1, safety: full power operation, substitute manual work mode completely, can realize separate men from machines, operational security is high, and labor intensity is little; 2, high efficiency: timber boats and ships, ship bar, flank goods draw get that production time is about whole ship operation 2/3, and the height of this link operating efficiency is the principal element determining whole ship production time.Adopt manual work mode, need workman to climb on timber and extract steel rope, carry out bundling, link up with, decoupling device operation.After adopting the present invention, can manipulate fixture picking by excavating machine, fixture operating efficiency is more than 8 times of manual type, and efficiency significantly improves; 3, alerting ability: the present invention is easy to operate, at limited space and less operating personal, can carry out fast speed handling to circular material, expand the function of excavating machine.Particularly during the lotting of many tickets goods, excavating machine can operate the present invention and accurately capture, and single function ratio of provoking timber is better.4, convenience: mechanical linkage formula is taked in the present invention's design, decreases the hydraulic actuating cylinder between claw, simplifies the structure, installs also more flexible, saves manufacturing cost, maintain simultaneously with check also relative convenient.5, steadiness: the mode being provided with rear claw pipe link between the claw of front and back, makes can form perfect arcuate structure between front claw and rear claw, increases envelope size, improve the adaptation of product.And due to the design of front claw pipe link, front claw intensity is made to obtain reinforcement, improve the Stability and dependability of equipment when capturing major diameter timber and density larger material, this device can capture the circular material such as oil storage barrel, pipeline simultaneously, expands the range of use of excavating machine further.

A kind of beneficial effect of multi-purpose machinery pawl is: a kind of multi-purpose machinery pawl can be arranged in vapour pressure or hydraulic compressor mechanical arm, undertaken stretching to anywhere by mechanical arm and carry out clamping the bar material got and vary in size, and dismantling, change conveniently, is a kind of multiduty mechanical arm tonger for subsequent use.
