Abstract
A lifting appliance special for overhauling an isolating switch comprises an upper arm and a lower arm which are arranged vertically, the lower end of the upper arm is inserted into a counter bore at the upper end of the lower arm, and is fixed by a pin, an erector arm is fixed at the upper part of the upper arm, and provided with a guiding pull ring and a fixed pulley, the fixed pulley is wound by a rope with a lifting hook, and at least one group of hoops are arranged on the side surface of the lower arm, and are connected with the lower arm by a support arm. By adopting the technical scheme, the adjacent interval power failure caused by the operation scope of a crane is avoided, the operation radius is small and the safety factor is high, the work efficiency is greatly improved, the operation is simple, the manufacturing and using cost is lower, so that the lifting appliance is beneficial to being promoted and used in the same industry.
Description
Technical field
The utility model belongs to a kind of maintenance accessory equipment, relates in particular to a kind of hanging device that is used for disconnector.
Background technology
Model be LW16 17; LW10 the disconnector of 11 types, be usually used in hard bus and connect, lifting maintenance at ordinary times need be stopped transport operating bus and adjacent spaces, re-uses large-scale lifting vehicle and lifts this isolated switchgear, cause power failure range extension, field activity safety factor to reduce, extremely inconvenience works together.Efficient is lower, influences bigger.
The utility model content
Technical problem to be solved in the utility model provides a kind of disconnector simple in structure, easy to use maintenance special hanger.
Adopt following scheme in order to solve above technical matters: a kind of disconnector maintenance special hanger, the upper arm and the underarm that comprise vertical setting, the upper arm lower end is inserted in the counterbore of underarm upper end and is passed through dowel fixes, upper arm top is fixed with crane arm, crane arm is provided with guiding draw ring and fixed pulley, twining the rope that has suspension hook on the fixed pulley, the underarm side is provided with at least one group of anchor ear, and anchor ear is connected with underarm by hold-down arm.
Described anchor ear is two groups, being arranged on the same straight line of level.
Described fixed pulley is arranged on the crane arm end away from upper arm.
The diameter of described upper arm is less than the internal diameter of counterbore, and the degree of depth of counterbore is 20 ~ 50cm, and counterbore is provided with two pin holes on same straight line, and the upper arm bottom is provided with and the corresponding through hole of pin hole.
Adopt technical solutions of the utility model, the adjacent spaces of having avoided causing because of the crane action radius has a power failure, the little safety factor height of operating radius, work efficiency have very big lifting and simple to operate, manufacturing cost and use cost is lower, be beneficial in the same industry to promote the use of.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is running condition figure of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of disconnector maintenance special hanger, the upper arm 1 and the underarm 2 that comprise vertical setting, insert in the counterbore 3 of underarm 2 upper ends upper arm 1 lower end, the diameter of upper arm 1 is less than the internal diameter of counterbore 3, and the degree of depth of counterbore 3 is 20 ~ 50cm, and underarm 2 tops are provided with two pin holes 4 on same straight line, upper arm 1 bottom is provided with and pin hole 4 corresponding through holes, inserts pin 5 and fix with spacing in pin hole and through hole; Upper arm 1 top is fixed with crane arm 6, and crane arm 6 is provided with guiding draw ring 7 and fixed pulley 8, and fixed pulley 8 is fixed on the crane arm 6 away from an end of upper arm, is twining the rope 9 that has suspension hook on the fixed pulley 8, and rope 9 passes guiding draw ring 7; Underarm 2 sides are provided with that 10, two groups of anchor ears 10 of two groups of anchor ears are horizontally disposed with and on vertical same straight line, anchor ear 10 is connected with underarm 2 by hold-down arm 11.
Underarm is 3 meters long Ф 80 steel pipes, and upper arm is 3 meters long Ф 70 steel pipes, and crane arm is long 1.5 meters Ф 70 steel pipes, between two anchor ears and the underarm respectively Ф 70 steel pipes by long 0.4 meter connect.
Principle of work: as shown in Figure 2, underground 500cm is bought in underarm in suitable position near the at first selected disconnector, then upper arm is inserted in the counterbore of underarm 30cm, anchor ear 10 is fastened on the column 12 of disconnector below, pin is inserted in the assembling back, prevents to save up and down rotation; After the assembling of disconnector maintenance special hanger finished, by suspension hook lifting disconnector disconnecting link 13, rope passed the guiding draw ring, and lifting rope utilizes manpower lifting disconnector disconnecting link.After the disconnector disconnecting link breaks away from framework, extract spacing and the fixing pin of usefulness, spur rope as required and arrive suitable position, the disconnector disconnecting link is slowly put down by guiding draw ring rotation upper arm; Dress is returned in the maintenance back.
