Description
Technical field
The utility model relates to the bont technical field, specifically is a kind of rotary lifting device.
Background technology
Along with the increase of technology innovation project, the substation that puts into operation carry out equipment replacement especially the replacing of disconnector become the vital task that we face.Often can't use mechanical equipments such as crane in the replacing process of disconnector, the labour-saving that how to save time in limited space becomes basis in the new disconnector lifting key of this work.Traditional simple lifting appliance adopt framework fixedly the method for suspension centre, men hoisting have in work progress that suspension centre can't rotate, required men hoisting tractive force reaches the long disadvantages such as swinging excessive initiation potential safety hazard that causes of hauling rope more greatly.
Summary of the invention
In order to solve the shortcoming of above-mentioned prior art, the utility model provides a kind of rotary lifting device, and this device can arbitrarily angledly rotate, and the tractive force that needs is little and be convenient to control, and has commonality widely.
Task of the present utility model realizes by following approach: a kind of rotary lifting device, comprise pillar, and be used for fixing the anchor fitting of pillar, be installed in the lifting appliance on the pillar; It is characterized in that: described pillar is made up of upper support bar and lower support bar; Upper support bar is connected with lower support bar and upper support bar can rotate in lower support bar; Described lifting appliance comprises the quiet assembly pulley that is fixed on the lower support bar; Be installed in the cross-arm of upper support bar upper end, be fixed with hanger, be hung with running block on the hanger at the two ends, lower surface of cross-arm.
The utility model has the advantages that: (1) has adopted rotatable design, solves single suspension centre difficult problem in stays; (2) adopt running block, significantly reduced lifting traction force; (3) adopt quiet pulley, changed the lifting traction force direction, be convenient to control tractive force; (4) pillar has adopted multiple size to cooperate on fixing, is applicable to the disconnector basis of each voltage class, improve the commonality of this device.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation;
Fig. 2 is the fixture structure scheme drawing.
Among the figure: 1, cross-arm; 2, hanger; 3, diagonal brace; 4, upper support bar; 5, running block; 6, bearing; 7, folder muscle; 8, lower support bar; 9, hook; 10, anchor fitting; 101, anchor ear; 102, backboard; 11, quiet assembly pulley.
The specific embodiment
As shown in Figure 1, a kind of rotary lifting device has a pillar, and pillar is made up of upper support bar 4 and lower support bar 8; Upper end at lower support bar 8 has circular groove, and bearing 6 is housed in the circular groove, and upper support bar 4 is connected with lower support bar 8 by bearing 6; Upper support bar 4 and lower support bar 8 adopt steel pipe in the present embodiment, and bearing 6 adopts the method that embeds lower support bar 8 inwalls fixing concentric to guarantee lower support bar.In order to increase upper support bar 4 and lower support bar 8 intensity in the junction, upper support by 4 and the junction of lower support bar 8 folder muscle 7 is installed.Upper support bar 4 upper ends are equipped with lifting appliance, and lifting appliance is made up of with the cross-arm 1 that is installed in upper support bar 4 upper ends the quiet assembly pulley 11 that is fixed on the lower support bar 8; Two ends, lower surface at cross-arm 1 are fixed with hanger 2 respectively, are hung with running block 5 on the hanger 2; In order to increase the fastness of cross-arm 1, between cross-arm 1 and upper support bar 4, diagonal brace 3 is installed.Lower support bar 8 is installed on cement pole or the steel pipe by two anchor fittings 10.
As shown in Figure 2, anchor fitting is made up of anchor ear 101 and backboard 102, and anchor ear 101 and backboard 102 are fixed on pillar on cement pole or the steel pipe.
The working process of disconnector is installed: at first according to corresponding anchor ear 101 of the size Selection on disconnector basis and backboard 102, lower support bar 8 is fixed on running block 5 and the quiet assembly pulley 11 that assembles after go up on the basis among Fig. 1, hook 9 is hung on the single-phase disconnector of required lifting, utilize dynamic and static assembly pulley tractive force can be applied on this switch; Then single-phase disconnector is promoted to proper height, can makes cross-arm 1 rotational angle by bearing 6, thereby single-phase disconnector is turned to basic top.Once more, we winch to other two-phase disconnector on the basis according to identical order single-phase disconnector to be done simple fixing back.During this time, can need with the dismounting of Fig. 1 pillar once be fixed on another basis because of the factor of position and angle; Behind the three-phase isolation switch levelling capturing, we firmly are welded on it on basis.At last, the vertical links and the waling stripe of disconnector is installed, and in this process, noted regulating the opening degree same period alternate of disconnector with each.
Use the utility model carries out the disconnector replacing in the substation interval step is as follows:
1, work is prepared: check preparation, check one by one by instrument, material list that the work responsible official lists.
2, select supporting fixedly anchor ear and backboard according to on-the-spot disconnector key dimension, the fixed hoisting device is assembled dynamic and static assembly pulley.
3, remove original disconnector interphase connecting rod, each hangs down mutually successively with original disconnector to utilize suspender belt and this device; In this process, lifting appliance is wanted dismounting twice, should carry out the fixing and inspection work of device.
4, new disconnector is fixing in ground phase-splitting assembling, lift successively to the basis according to reverse order of last step then and carry out simple fixingly, in this process, lifting appliance is wanted dismounting twice, should carry out that device is fixing to reach inspection work.
5, remove dynamic and static assembly pulley successively, hook and lifting appliance.
6, adjust each isolated switch level and vertical distance and meet producer's installation requirement after, with each and basic secure fixation, actuating phase place vertical links and alternate kinematic link are installed successively.
7, regulate vertical links place phase edge of a knife open position, and by the adjustment of interphase connecting rod being regulated the edge of a knife open position of all the other two-phases.
8, respectively the disconnector that assembles is manually reached electronic divide-shut brake test, check each connecting bridge position and state.
9, withdraw scene, end operation.
