Abstract
The utility model discloses a device for dismantling a movable pulley shaft of a hectometer heavy rail crane, aiming at solving the problem that the movable pulley shaft of the current hectometer heavy rail crane is difficultly dismantled, and the time and the labor are wasted. The device is mainly composed of a fixed support, a connecting flange, a screw rod and an inner barrel, wherein a connecting plate which can be connected with a movable pulley seat is arranged at the front end of the fixed support, and the inner barrel is fixedly arranged at the rear end of the fixed support; the screw rod penetrates through the inner barrel, and the connecting flange which can be connected with the end part of the movable pulley shaft is fixedly arranged at the front end of the screw rod; and a square head is arranged at the rear end of the screw rod. As the fixed support is connected with the movable pulley seat into a fixed frame, the screw rod is rotated to move along the inner barrel to the rear end of the fixed support and further drive the connecting flange and the movable pulley shaft to move outwards, and therefore the movable pulley shaft is drawn out. The operation is convenient and saves labor, and the movable pulley shaft can be easily drawn out by the operation of one person. The dismantling time is reduced to one hour from original four hours, the maintenance and repair efficiency is increased, and the workpiece damage is reduced.
Description
Technical field
The utility model relates to a kind of device for hundred meters heavy rail crane movable pulley wheel shafts of dismounting.
Background technology
Hundred meters heavy rail cranes are used for hundred meters high speed heavy rails of lifting, and the operation of this crane directly has influence on the production of hundred meters heavy rails and dispatches a car.This crane comprises two groups of running blocks, and every group is fitted together by 4 pulley sheets, respectively is fixed on the two ends of 3 meters high long drop in beams top.Because drop in beam can not be put upside down and a whole set of assembly pulley can't the whole series be pulled down, so must carry out parts dismounting and assembling above the drop in beam platform of 3 meters high, cooperated simultaneously by three to four operating personnels and complete, but inspection platform is narrow, only has the space that can hold people's operation, and be installed with four pulley sheets on the movable pulley axle and be transverse on movable pulley bearing on drop in beam, movable pulley axial length is 1000mm, the resistance of extracting the movable pulley axle out is very large, beat to pull down with original sledgehammer and not only easily hurt part of appliance and length consuming time.
Summary of the invention
The purpose of this utility model is to overcome the prior art defective, and a kind of device for hundred meters heavy rail crane movable pulley wheel shafts of dismounting is provided, and only needs an operating personnel can easily pull down the movable pulley wheel shaft at short notice.
The technical solution of the utility model is achieved in that a kind of device for hundred meters heavy rail crane movable pulley wheel shafts of dismounting, it is, it mainly is comprised of hold-down support, connecting flange, screw mandrel and interior swivel nut, the hold-down support front end has the connecting plate that can be connected with the movable pulley seat, the hold-down support rear end is fixed with interior swivel nut, screw mandrel passes interior swivel nut, and the screw mandrel front end is fixed with the connecting flange that can be connected with movable pulley wheel shaft end.
Preferably, the screw mandrel rear end is square toes.
The utility model connects into a fixed frame by hold-down support and movable pulley seat, rotary screw makes screw mandrel mobile to hold-down support rear end generation along interior swivel nut, and then drive connecting flange and the movable pulley wheel shaft outwards moves, thereby the movable pulley wheel shaft is pulled out, convenient and strength-saving, only need one man operation easily to extract the movable pulley wheel shaft out, the take-down time reduced to 1 hour by original 4 hours, improve overhaul efficiency, reduced the workpiece damage.
Description of drawings
Fig. 1 is the utility model structure and work schematic diagram.
In figure, the 1-hold-down support; The 2-screw mandrel; The 3-connecting flange; Swivel nut in 4-; The 5-connecting plate; 6-movable pulley seat; 7-movable pulley wheel shaft.
The specific embodiment
Be further described below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of device for hundred meters heavy rail crane movable pulley wheel shafts of dismounting, it mainly is comprised of hold-down support 1, connecting flange 3, screw mandrel 2 and interior swivel nut 4, hold-down support 1 front end has two connecting plates 5 that can be connected with movable pulley seat 6, hold-down support 1 rear end is fixed with interior swivel nut 4, screw mandrel 2 passes interior swivel nut 4, and screw mandrel 2 front ends are fixed with the connecting flange 3 that can be connected with movable pulley wheel shaft 7 ends.
Connecting flange 3 external diameters are less than or equal to movable pulley wheel shaft 7 diameters of axle, and three screws of three holes on connecting flange 3 and movable pulley wheel shaft 7 ends match, and can be fixed on movable pulley wheel shaft 7 axle heads to connecting flange 3 by bolt.Screw mandrel 2 passes connecting flange 3 centre bores, and the screw mandrel 2 root shaft shoulders are adjacent in connecting flange 3 counterbores also fastening, and screw mandrel 2 is threaded by T-shaped with the interior swivel nut 4 of hold-down support 1 rear end.Four lower margin holes on two connecting plates 5 of hold-down support 1 front end and the clamp bolt hole on movable pulley seat 6 match, and by bolt, hold-down support 1 are fixed on movable pulley seat 6.The screw mandrel rear end is square toes, with the square toes of spanner rotary screw rod 2 rear ends, pulls out movable pulley wheel shaft 7 by screw thread driving-belt movable wire bar 2.
Claims (2)
1. device that is used for hundred meters heavy rail crane movable pulley wheel shafts of dismounting, it is characterized in that: it mainly is comprised of hold-down support, connecting flange, screw mandrel and interior swivel nut, the hold-down support front end has the connecting plate that can be connected with the movable pulley seat, the hold-down support rear end is fixed with interior swivel nut, screw mandrel passes interior swivel nut, and the screw mandrel front end is fixed with the connecting flange that can be connected with movable pulley wheel shaft end.
