Abstract

The present invention provides a stringing method of main rope of crawler crane, and a method of the coarse-wire rope reeving between the up-down pulley block driven by seizing wire as a conveying rope by crane winch or exogenic winch as pulling winch when assembling large-scale crawling crane, replacing the artificial reeving hoisting cable mode by multiple assembling worker climbing hoister A type frame and big rod, the method achieves timesaving, labour saving, manpower saving effects, and reduces potential safety hazard.

Description

A kind of wire rope handling method of pedrail crane main rope
Technical field
The present invention relates to a kind of steel rope winding method when being used for the assembling of large-scale crawler crane, be particularly useful for the wire rope handling method of tracklaying crane main rope.
Background technology
Large-scale crawler crane crane is frequently cut to, steel rope wears around the work that becomes time-consuming a, effort all the time during each assembling crane, especially U.S. Manitowoc 4100WS type adds the ring beam crawler crane, has three cover steel ropes to need repeatedly to penetrate in assembly pulley to pass.
Luffing steel rope that large-scale pedrail crane uses and master winch wirerope diameter are generally at 22mm to 28mm, and the steel rope deadweight is 10Kg/m, add that steel rope often is being with torsion, and strength is very big.Wearing when mast is supported oneself rope, need the people to climb to host A type top of the trellis high more than 9 meters and go to wear around steel rope.So on the A type frame of both sides, want per two meters station one people, piecemeal transmission fag end.The people of A type top of the trellis also will wear the fag end of threading back and forth between pulley and lever under the situation of astasia, very difficult dangerous again, and often will repeat repeatedly could be successful.It is other and arrange many people to transmit in that reel is other to finish the balancing device of this need of work in A type top of the trellis and both sides, on big bar, needs 15 people at least, more needs more than three hour time; When wearing around suspension hook master winch steel rope, on big bar, need per five meters station one people to transmit fag end, the people also will carry steel rope and take action on bar, because can't bundle safety strap, so exist safe hidden danger.Comprise stand on the bar and wear personnel at the bar head around pulley, need tens people just can finish this work altogether.
For many years, wear in the work of steel rope at the assembling crane, adopt this is the time-consuming method of effort again always, and many consumptions are manually dangerous again.
Summary of the invention
Manually wear drawback in order to solve simple use, the invention provides a kind of wire rope handling method of pedrail crane main rope, adopt this method to raise labour efficiency, save manpower consumption, reduced the member and dropped into, improve safety control simultaneously around this construction method of steel rope.
The technical solution adopted in the present invention is, wire rope handling adopts following steps: 1. pedrail crane is equipped with and hangs steel rope that wall length adapts as hauling rope; 2. the hauling rope end is connected with coupling link with main rope; 3. the front end of hauling rope is worn successively around crane A type frame assembly pulley and luffing balancing device assembly pulley; 4. the front end that will wear the hauling rope that winds is locked on the crane elevator; 5. rotate elevator, twine hauling rope, drive main rope and wear successively around the crane assembly pulley; When 6. the crane main rope is towed to elevator, unties steel cable and connect, emit hauling rope, main rope is locked on the elevator, finish crane main rope wire rope handling process.
Be to improve effect, step 1. in, the steel rope that can select diameter 8mm-10mm for use is as hauling rope.
The breaking force of rope of diameter 8mm to 10mm is 58KN, has considered safety factor, satisfy fully the traction coarse-wire rope between assembly pulley, wear around requirement.
Description of drawings:
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Fig. 1 is a crane rope winding method scheme drawing of the present invention.
1. hauling ropes among the figure, 2. coupling link, 3. main rope, 4.A type frame assembly pulley, 5. elevator, 6. luffing balancing device assembly pulley, 7.A type frame.
The specific embodiment
Be example with 300 tons of pedrail cranes of 4100WS type below, the wire rope handling method of main rope is described, according to calculating, when all crawler crane assemblings, steel rope need from cylinder, emit and wear between assembly pulley around length be the most for a long time in assembling 4100WS mobile jib luffing rope, need wear around nearly 200 meters.So the seizing wire of selecting 200 meters, can satisfy the assembling requirement of the large-scale crawler crane of present major part as hauling rope.
As shown in Figure 1, use the method assembling crane, being equipped with a cover diameter need for every crane is that the steel rope of 8mm to 10mm is as hauling rope 1, and the end of hauling rope 1 is inserted into rope sling, weld a coupling link 2 at the luffing steel rope and the main rope 3 fag end places of every crane in advance, coupling link 2 can select for use the nut of suitable size to substitute, and the external diameter of nut is no more than the diameter of steel rope, and internal diameter is greater than the pin rod diameter of snap ring.
When wearing around steel rope, earlier that the end of hauling rope 1 and crane rope fag end coupling link 2 usefulness are the most small size snap ring is connected, then with the other end of hauling rope 1 along steel rope correct wear around direction with A type frame assembly pulley 4, the luffing balancing device assembly pulley 6 of required process wear one by one around, in this process, to guarantee to wear around correctly, avoid the intersection and the kink of steel rope.Haulage cable 1 is thinner, and it is lighter to conduct oneself with dignity, and people can be with fag end to act on one's own on A type frame and big bar, and the hauling rope fag end is thinner, torsion than I arbitrarily pulley room wear around.The front end fag end of the hauling rope 1 that winds is withdrawn into crane elevator 5, and is locked on the elevator 5, hauling rope 1 can be twined along with the rotation of elevator 5.
Slowly rotate elevator 5, allow the thickness steel rope all certain force of strain be arranged after, check that hauling rope 1 is whether all in the race inside of each pulley.Confirm errorless after, can be rotated further elevator 5, twine hauling rope 1, drive thick main rope 3 and from cylinder, emit, and along with hauling rope 14,6 in assembly pulley wear around.This process only needs four people, respectively on A type frame 7 top, assembly pulley 4,6 other, cylinder 5 other nurses, prevent from the steel rope job-hopping and block to get final product.When crane king wire fag end 3 meets the requirements of the position, stop action, and untie being connected of hauling rope 1 and main rope 3, finish wearing of steel rope around work.
Enforcement of the present invention makes everybody work that just can finish of original needs 15, and being reduced to maximum five people can realize; And will be reduced within one hour the time from original three hours.Greatly reduce labour intensity, reduced artificial input, improved efficient, can in construction, extensively adopt.
Though described embodiments of the present invention in conjunction with the accompanying drawings, those of ordinary skill in the art can make various distortion or modification in the scope of described claim.
