Abstract
The invention discloses a gripping device for loading and unloading a cylindrical material. The gripping device solves the problem that the existing steel wire rope fastener or other rope slings for loading and unloading cylindrical materials such as steel pipes and round steel are wore easily in binding hoisting so that the cylindrical materials slide off easily, need large worker labor intensity, do not realize worker-cargo separation, are unsafe and have low work efficiency. A rotation device of the gripping device is controlled by an external control valve so that gripping and unloading directions can be freely and automatically changed, rubber pads are installed on contact parts of external and internal gripping arms and the cylindrical material so that the damage on the outer surfaces (such as a rust-resistant paint layer and a corrosion-resistant layer) of the cylindrical material is avoided, and an elastic compression device of the gripping device realizes compression and falling prevention of a small amount of long cylindrical materials having small pipe diameters in gripping. The gripping device has a simple structure, is convenient for use, has low worker labor intensity, realizes worker-cargo separation, and is safe, reliable and durable.
Description
Technical field
The present invention is a kind of gripping apparatus that cylindrical material is used that loads and unloads.
Background technology
Along with the fast development of China's economy, the development of the industries such as oil and gas pipeline project construction, the pipelaying of petrochemical industry metallurgy industry, port dredging pipeline construction is very fast, and the demand of all kinds of tubing used increases day by day.Wherein, tubing transports the lifting of all transfer efficients, can greatly accelerate the progress of project construction.As everyone knows, the handling tubing mode that yard at stations and port and pier are current, generally to load and unload with wire line hitch or other ropes that the suspension hook of hoisting crane catches on pocket swing pipe material, the tubing that lifts essential first with steel rope or other ropes with being lifted into again on transport trolley after artificial binding firmly, the entrucking direction of tubing has artificial rotation to regulate, lay down tubing and also must manually unclamp steel rope or rope, in whole hoisting process by many people compounding practice, during lifting, artificial directly contact tubing is adjusted direction, these are all easy to cause the accident and personal casualty, whole handling tubing process work efficiency is low simultaneously, people's goods does not separate, dangerous.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, thereby a kind of gripping apparatus that cylindrical material is used that loads and unloads is provided, mainly solve the problems such as existing tubing handling process complex operation, dangerous large and work efficiency are low
The concrete technical scheme that the present invention adopts is: a kind ofly load and unload the gripping apparatus that cylindrical material is used, it comprises: slewing arrangement, hydraulic ram, column, bearing pin I, bearing pin II, outer gripping arm, 1/4th elliptic springs, rubber pad, interior gripping arm, bearing pin III, synchronising (connecting) rod, bearing pin IV, nylon wheel, its key point is: outer gripping arm is used bearing pin II to be connected with column lower end respectively with interior gripping arm, and synchronising (connecting) rod two ends are used bearing pin III to be connected with outer gripping arm and interior gripping arm respectively; One end of two hydraulic rams is used bearing pin I to be connected with column upper end respectively, and the other end uses bearing pin I to be connected with outer gripping arm and interior gripping arm respectively; Rubber pad use bolt be arranged on respectively outer gripping arm and interior gripping arm with " contact surface " of grabbed material on; / 4th elliptic springs use bolt to be arranged on column; Porose on nylon wheel, use bearing pin IV to connect by the grasswort hole of 1/4th elliptic springs; Slewing arrangement uses bolt to be arranged on column top, and centre revolving joint uses bolt to be arranged on column top, and slewing arrangement uses hydraulic oil pipe to be connected with hydraulic ram by centre revolving joint.
Above-mentioned technical scheme, is characterized in that: slewing arrangement can be connected with elevator machinery vehicle; Rubber pad uses bolt to be arranged on respectively on " contact surface " of outer gripping arm and interior gripping arm and the material of grabbing effectively to have protected tubing material outside face (anti-rust paint, anti-corrosion layer etc.) injury-free; / 4th elliptic springs use bolt to be arranged on column, porose on nylon wheel, use bearing pin IV to connect by the grasswort hole of 1/4th elliptic springs, and assembling forms a kind of elastic pressuring clamping device.
Compared with prior art, the present invention utilize external control cock control hydraulic rotating device can change arbitrarily capture and unload the direction of putting, when use capture and unload put very convenient; Utilize the flexible and synchronization link mechanism of external control cock control hydraulic ram to control outer gripping arm and interior gripping arm, realize the crawl of tubing material and unload and put; Outer gripping arm " contacts " part with interior gripping arm with tubing material, and rubber pad is installed, and has effectively protected tubing material outside face (anti-rust paint, anti-corrosion layer etc.) injury-free; The pressing regulation device that utilizes 1/4th equipped elliptical flat-plates of gripping apparatus and nylon wheel to form, regulate lifted different tube diameters, longer tubing crawl afterwards to unload put before equilibrium problem in process.Because it can rotate by 360 degree, accurate positioning, can adjust handling direction automatically, firmly grasp force, and the convenient of pressing regulation device installed, adjusted, and whole handling process can be completed by operator one people, makes it to be applicable to very much the loading and unloading operation of tubing material.Both expand operating range, ensured the safety of tubing handling process, increased substantially again work efficiency.Gripping apparatus is simple in structure, easy to use, and labour intensity is low, and people's goods separates, safe and reliable, durable in use.
