The change steel rope device 100 of hoisting crane of the present utility model is on the ground that places below the hoisting crane 200 as shown in Figure 1.The structure of exchange wire rope device 100 is described in detail below.
Change steel rope device 100 of the present utility model is furnished with a underframe 6, and following parts are installed on underframe 6:
New rope reel mount pad 13, it is equipped with several new rope reels 7 that have new steel rope (present embodiment is 2);
Be arranged on other several of new rope reel mount pad 13 and accommodate the useless rope reel 5 (present embodiment is 2) of receipts of useless steel rope;
Be arranged on useless rope reel 5 other at least one of receipts and have the friction drum 3 (present embodiment is 1) of tapering, for increasing the frictional transmission effect, each friction drum 3 is other also establishes predetermincd tension devices 2 (present embodiment is the predetermincd tension pulley) that produce predetermincd tension, and described friction drum 3 and predetermincd tension device 2 are cantilever support the outside of bearing (friction drum 3 and predetermincd tension device 2 have only a side to have bearing respectively) separately;
At the predetermincd tension device 2 other Collapsible support frames 9 that are provided with, the top of bracing frame 9 is equipped with leading sheave 1, when equipment does not use, whole bracing frame 9 is folding downwards, minification, so as carrying, or put into freight container and carry, the purposes of above-mentioned leading sheave 1 is the pulley of putting on the shelf that new steel rope is imported suspender 20;
Drive the actuating device 4 of receiving useless rope reel 5, friction drum 3 and predetermincd tension device 2.
On the above-mentioned underframe 6 the forklift socket is arranged, whole change steel rope device 100 can directly be carried with forklift, and interior carrying also can pack into the container.
Two useless rope reels 5 of receipts are done the tapering shape respectively in the present embodiment, wherein taking off end is conelet degree end, the other end is big tapering end, purpose is to be convenient to volume useless rope is thereon easily broken away from dismounting from the little end that takes off of diameter, this reel can be recycled, the center and the axle 12 of the useless rope reel 5 of these receipts connect, the end that takes off of receiving useless rope reel 5 has detachable flange baffle plate 10, this detachable flange baffle plate 10 is connected with the big tapering end of receiving useless rope reel 5 by bolt 14, remove bolt 14, this detachable flange baffle plate 10 can be removed, so that useless rope is removed from reel.After treating that useless rope is finished dismounting, again should 10 times anchored in place of detachable flange baffle plate to receiving on the useless rope reel 5, for next use.The axle 12 of the useless rope reel 5 big tapering ends of these receipts is made squarely, insert in the square hole of actuating device 4, so that transfer torque, axle 12 other ends are bearing on the bearing at end seat 11, bearing seat 11 is by last, the split-type shaft bearing that following two semiaxis bearings are formed, axle 12 axial location are on first bearing seat, bolt 14 is removed, first bearing seat of bearing seat 11 can be removed, axle 12 axially just lost the location, can receive useless rope reel 5 withdraws from actuating device 4 together with axle 12 square hole, the useless rope reel 5 of whole receipts can be carried to and need the place, the rope that will give up withdraws from, and restores an one-tenth reel, for using next time.
The rope process of changing of this device (is example with freight container lifting mechanism steel rope replacing):
Earlier container handling crane 200 suspenders 20 are put to the ground (see figure 2), and the steel rope on the main hoisting drum is all emitted, in machine room, corresponding two ends are coupled together, form closed circuit, this programme can all change main hoist rope simultaneously, at this moment form two closed circuit, it is other that change steel rope device 100 is transported to suspender 20, two new rope reels 7 that new steel rope is housed are installed on the new rope reel mount pad 13 of change steel rope device 100, leading sheave place at 21 1 ends of putting on the shelf of suspender 20 cuts off with two closed circuit useless ropes, and the useless rope in the top of otch is introduced two useless rope reels 5 of receipts of receiving useless rope.The useless rope in the bottom of otch is connected with the new rope of quick binding clasp 8 with new rope reel 7, actuating device 4 drives two useless rope reels 5 of receipts and accommodates useless steel rope, when useless rope is constantly taken in useless rope reel 5, new steel rope constantly is pulled out, be around the various pulleys in closed circuit, after useless rope is all taken in useless rope reel 5, just new steel rope finished all wear around.Remove useless rope and new being connected of restricting, cut off new rope when again two new rope reels 7 being emitted the requirement rope simultaneously, two ends of this stylish rope are still on ground, also to manage to make two ends of new rope to get back to the main hoisting mechanism reel of hoisting crane below, therefore, then do the work of second step, two ends of will newly restricting couple together with quick coupling, and it is closed circuit that new rope is formed, then around going into predetermincd tension device 2, again on the friction drum 3 around three the circle more than, drive predetermincd tension device 2 and friction drum 3, the junction, two ends of new rope is introduced into machine room gradually, and the place stops until hoisting drum, remove the connection of two ends of new rope, and will newly restrict around going on the corresponding roller, pressing plate fixes, and this case once can only be urged to machine room to the new rope of a closed loop, same way, the introducing machine room is dragged in two ports connections of new rope of second closed loop, and be connected on the hoisting drum, the driving lifting mechanism will newly be restricted and be taken on the main hoisting drum, promote overhead behind the needs height until suspender, change the rope end-of-job.
Work: the top chock that will receive the bearing seat 11 of useless rope reel 5 is removed afterwards, axle 12 loses axial location, withdraw from receive the square toes of useless rope reel 5 from square hole together with axle 12, at this moment, the useless rope reel 5 of whole receipts can be hung rope changer 100, deliver to and receive useless rope place, the useless rope reel 5 of detachable flanged plate 10 and receipts is thrown off, just the rope that all gives up can be withdrawed from reel, detachable flanged plate 10 reduce afterwards in receiving on the useless rope reel 5, and will receive useless rope reel 5 and be installed onto on the rope changer 100, for use next time.
After this rope changer flowed and to change rope, a cover can be many hoisting crane services, and whole change owner raising line once, worked and all carried out on ground, and is safe, reliable, convenient, fast.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, all will drop in the scope of claim of the present utility model variation, the modification of the above embodiment.
