Description
Technical field
A kind of device for adjusting bridge crane steel wire rope counter-jib is the utility model is related to, especially large-tonnage bridge-type rises
Heavy-duty machine, belong to bridge crane auxiliary apparatus for repairing technical field.
Background technology
When changing bridge crane steel wire rope, especially large-tonnage bridge crane steel wire rope, master file steel wire rope are all
Acted on and formed simultaneously by four steel wire ropes.At present, well known steel rope replacing method is all to drive new steel wire rope with old steel wire rope,
Change when, the wire rope wedge form joint installed on old steel wire rope counter-jib is dismantled, by the steel wire rope head at wedge joint with
New steel wire rope connection, while the pressing plate of old steel wire rope other end is disassembled, the new steel wire rope into disk is placed on steel wire rope pallet,
Pallet can rotate, and the steel wire rope so newly changed is not in just the phenomenon tightened.Start master file motor, old steel wire rope is immediately
By on new rope belt to reel, after the completion of four steel wire ropes are all changed, then fixation and the steel wire rope wedge shape of pressing plate are carried out
The installment work of joint, after whole installations, it is necessary to be adjusted to steel wire rope counter-jib, ensure that four steel wire ropes are same
When uniform stressed.Found in real work, if steel wire rope counter-jib is uneven, plate hook is landed must again and be laid flat, will
After the bearing pin and steel cable clamp of wire rope wedge form joint are all removed, then readjust installation, so since, steel of adjustment
Cord counter-jib needs a hour at the soonest, wastes time and energy, and influences to produce.
Utility model content
The utility model purpose is to provide a kind of device for adjusting bridge crane steel wire rope counter-jib, can quickly adjust
Bridge crane steel wire rope counter-jib, operating efficiency is improved, solve problem present in background technology.
The technical solution of the utility model is：
A kind of device for adjusting bridge crane steel wire rope counter-jib, includes upper plate, riser, lower plate, brace, bolt hole
With steel wire rope one, upper plate and lower plate parallel arrangement, it is fixedly connected between upper plate and lower plate by riser, forms U-shaped frame, U-shaped frame
Interior upper plate is provided with bolt hole and wire rope hole, and one end of steel wire rope one through wire rope hole and is fixed in U-shaped frame, U-shaped
Brace is provided between upper plate and riser in frame.
The other end of the steel wire rope one is connected with one end of steel wire rope two, the other end and the overhead traveling crane main drum of steel wire rope two
Connection, that one end that steel wire rope two is connected with steel wire rope one are provided with wedge joint, and U-shaped frame is stuck in overhead traveling crane plate hook by fixing bolt
On crossbeam.
The lower plate upper surface is in broached-tooth design.
One end of the brace and upper plate weld, the other end and the riser of brace weld.
Using the utility model, in steel wire rope counter-jib pre-adjustment, one is accomplished fluently in wedge joint one end of steel wire rope two
After individual steel cable clamp, wedge joint one end of steel wire rope two is connected on steel wire rope one, at the same four U-shaped framves are symmetrical
Be stuck on overhead traveling crane plate hook crossbeam, start overhead traveling crane master file, progressively stretch the wedge joint of steel wire rope two tightly, stretch next, see steel wire
Rope two wedge joint relative to overhead traveling crane plate hook bottom distance, it is possible to measure the length of steel wire rope two, and then be adjusted.
The beneficial effects of the utility model are：Bridge crane steel wire rope counter-jib can be quickly adjusted, improves work
Efficiency, reduce the labor intensity of worker.
Brief description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model top view；
Fig. 3 is the utility model use state diagram；
In figure：Upper plate 1, riser 2, lower plate 3, brace 4, fixing bolt 5, steel wire rope 1, overhead traveling crane plate hook crossbeam 7.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1,2, a kind of device for adjusting bridge crane steel wire rope counter-jib, upper plate 1, riser 2, lower plate are included
3rd, brace 4, bolt hole and steel wire rope 1, upper plate 1 and lower plate 3 are arranged in parallel, solid by riser 2 between upper plate 1 and lower plate 3
Fixed connection, forms U-shaped frame, and the upper plate 1 in U-shaped frame is provided with bolt hole and wire rope hole, and one end of steel wire rope 1 passes through steel wire
Cord hole is simultaneously fixed in U-shaped frame, and brace 4 is provided between the upper plate 1 and riser 2 in U-shaped frame.
In the present embodiment, the length of steel wire rope 1 is one meter, a diameter of 15mm, and fixing bolt 5 is M24 high-strength bolts, on
Plate 1, riser 2 and lower plate 3 are 20mm steel plates, and upper plate 1, riser 2 and lower plate 3 are welded into U-shaped frame, and the upper surface of lower plate 3 is saw
Tooth-shape structure, to increase its end-face friction, one end of steel wire rope 1 is penetrated in U-shaped frame by wire rope hole, and make a call to one
Wire line hitch, then by one piece of sheet metal welding, prevent steel wire rope from coming off.
In steel wire rope counter-jib pre-adjustment, beaten in wedge joint one end of steel wire rope two what a steel cable clamp it
Afterwards, wedge joint one end of steel wire rope two is connected on steel wire rope 1, while four U-shaped framves is symmetrically stuck in a day sweep
On hook crossbeam 7, start overhead traveling crane master file, progressively stretch the wedge joint of steel wire rope two tightly, stretch next, see that the wedge shape of steel wire rope two connects
Head need not adjust counter-jib relative to the distance of overhead traveling crane plate hook bottom if being of the required size.If size difference is super
Bid alignment request, it is possible to according to corresponding size, readjust the steel cable clamp position of fastening steel wire rope two.Adjustment is completed
Afterwards, the steel cable clamp of steel wire rope two is stuck on steel wire rope 1.
