The detachable and portable lifting tool comprises a supporting arm and a movable arm, wherein the supporting arm comprises a support post, a flange is welded at one end of the support post, a bearing is embedded in a port of the other end of the support post, and a movable shaft provided with a lower flange is embedded in the inner diameter of the bearing; and the movable arm comprises a main arm and a telescopic lifting arm, a connecting flange is arranged on the main arm, a bracket is welded at one end of the telescopic lifting arm, a fixed pulley is arranged on the bracket, the other end of the telescopic lifting arm is inserted into the inner diameter of the main arm, and the supporting arm and the movable arm are connected with the connecting flange through the lower flange. According to the detachable and portable lifting tool, the supporting arm is connected with the transformer and the movable arm through flanges, and a core of the tapping switch is stably lifted without any collision, so that the completeness of equipment in the lifting process can be effectively guaranteed, the work efficiency is improved, worker waste is reduced, and the switch can be protected from being damaged.
Description
Technical field
The utility model relates to a kind of removable Portable lifting device, particularly relates to the lifting of sub-connecting switch of transformer, belongs to lifting device.
Background technology
Field for Large Transformer is changed while repairing shunting switch, because scene does not have the crane lifting instrument, give the extraction of shunting switch and lay and caused certain difficulty, traditional method is that the constructor pinions switch with rope, several individuals propose switch together, this has not only caused personnel's waste, may cause certain damage, inefficiency to switch simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of convenience, high efficiency, removable Portable lifting device that labour intensity is low.
Technical solution:
The utility model comprises: hold-down arm, movable arm, and hold-down arm comprises: pillar, pillar one end welded flange, the port embedded bearing of the pillar other end, the inner radius of bearing is inlayed a movable axis with lower flange; Movable arm comprises: principal arm, telescoping boom, and principal arm is provided with butt flange, an end welding support of telescoping boom, support is provided with fixed pulley, and the other end inserts the internal diameter of principal arm, and hold-down arm is connected with butt flange by lower flange with movable arm.
Described telescoping boom can move in principal arm.
Described principal arm is provided with the adjusting nail pressing.
Described pillar is provided with the turning cylinder dowel bolt.
The utility model hold-down arm is connected with voltage transformer by flange, hold-down arm is connected with movable arm by flange, the fuse of shunting switch is steady in the process of lifting, collisionless, can actv. guarantee intact in hoisting process of equipment, increase work efficiency, reduce personnel's waste, guarantee that switch is not damaged.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model working state figure.
The specific embodiment
The main body of the utility model pillar 2 is φ 60 steel pipes, and an end welded flange 1 is connected with the transformer box edge bolt, the port embedded bearing 3 of the other end, and the inner radius of bearing 3 is inlayed a movable axis with lower flange 4.Movable arm is comprised of principal arm 6 and telescoping boom 8, principal arm 6 is that φ 60 steel pipes, telescoping boom 8 are φ 50 pipes, one end welding support 9 of telescoping boom 8, support 9 is equipped with fixed pulley 10, and the inner radius that telescoping boom 8 other ends insert principal arm 6 forms the movable telescopic arm.Length center and end at principal arm 6 steel pipes evenly arrange jackscrew, for the fixing length of telescoping boom.The other end at principal arm 6 steel pipes is welded to connect flange 5 and bracing frame.
In use, flange 1 is fixed on the transformer oil tank edge bolt the utility model, and lower flange 4 is used bolted with butt flange 5.The length of adjusting activity arm and the central vertical of shunting switch, start lifting after the adjusting nail pressing 7 on fastening principal arm 6, the turning cylinder dowel bolt on fastening pillar 2.Buddhist nun's suede lifting rope is passed to the rear colligation of fixed pulley 10 on the suspension ring of shunting switch, slowly lifting, after shunting switch all hangs out fuel tank, loosening fastening turning cylinder dowel bolt, turn on fuel lid to be repaired by the shunting switch fuse.
Again shunting switch is turned to the position hung out after fixing, slowly install, until each parts complete whole hoisting process after being all on board.
