Abstract
The utility model relates to a portable foldable lifting device which is an auxiliary device applied to exporting, handing over, routine tests and equipment overhaul and replacement of a transformer below 220kV and creates good conditions for field lifting and transportation. The portable foldable lifting device adopts the structure that an underframe is provided with foldable support rods, every two support rods are connected through a connecting pin, an electric hoist is installed at the top end of each support rod, and a control handle is connected with each electric hoist. The portable foldable lifting device can be used for effectively fixing and installing power equipment and creating the conditions for field test and installation. With the advantages of small volume, flexibility, good environmental suitability, safety, reliability and the like, the portable foldable lifting device can meet the needs of outdoor field test and installation.
Description
Technical field
The utility model relates to a kind of lifting appliance, relates in particular to a kind of portable folding lifting appliance, is to be applied to carry out 220kV and following voltage transformer dispatches from the factory, handing-over, routine test and equipment rebuilding are changed auxiliary device, belongs to the electric power application.
Background technology
Test such as electrical equipment such as voltage transformer, isolation switch is installed and is carried out under outdoor field environmental condition usually.Carrying out in-place test and equipment when installing, the time regular meeting carry out the carrying and the lifting of test facility, traditional method for carrying is a dead lift and driving lifting.The a dead lift safety factor is low, labour intensity is big, to the reliability of object do not ensure and efficient low.Because the restriction of condition, condition does not have under the situation of lifting appliance at the scene, brings very big inconvenience to hoisting object, and the equipment that has a strong impact on is installed, and particularly outdoor work is more obvious.Bring very big obstruction for the installation of equipment so adopt a dead lift and driving lifting always.
Summary of the invention
The utility model is at above-mentioned problems of the prior art, a kind of portable folding lifting appliance is provided, the equipment that solved in the prior art is installed the problem with very big obstruction, the utility model can effectively carry out under various environment, maximum conserve space and large-scale lifting appliance, increase work efficiency, alleviate personnel labor intensity, guarantee the safety of the person and equipment.
The technical solution of the utility model is as follows:
Underframe is provided with collapsible strut bar, links to each other by attachment pegs between every joint strut bar; The top of strut bar is equipped with electric block, and control handle links to each other with electric block.
The bottom of described underframe is provided with cardan wheel, and the trailing wheel of cardan wheel is provided with brake.
Described electric block is a minisize electric hoist.
The utility model has the advantages of as follows:
1, convenient transportation because strut bar adopts collapsible successively placement, thereby has been saved the space.
2, install simple and easyly, adopt attachment pegs between the strut bar, making between the strut bar provides convenience to installation by Rotate 180 degree mutually.
3, easy to operate, operating control handle gets final product the height that the free adjustment object need lift by crane.
4, safe and reliable, adopt and be with the trailing wheel of stopping to prevent that lifting machine from sliding in the lifting process, guarantee the reliability of lifting object, reduce unnecessary loss.
5, adopt minisize electric hoist, operate steadily noiselessness.
Volume is little, light weight, good environmental adaptability, lifting convenient, safe and reliable, for electrical equipment test, overhaul, replacing provide good environment, and then increase work efficiency, and warranty test is installed safety.

Structural representation when Fig. 1 folds for the utility model.
Structural representation when Fig. 2 launches for the utility model.
Among the figure, 1, underframe, 2, strut bar, 3, electric block, 4, control handle, 5, attachment pegs, 6, cardan wheel.
The specific embodiment
The bottom of underframe 1 is provided with cardan wheel 6, and the trailing wheel of cardan wheel 6 is provided with brake; Underframe 1 is provided with collapsible strut bar 2, links to each other by attachment pegs 5 between every joint strut bar 2; The top of strut bar 2 is equipped with minisize electric hoist 3, and control handle 4 links to each other with minisize electric hoist 3.
The utility model is a departure point with portable, lightweight, on-the-spot practicality all the time, adopts light material in a large number, has taken into account the mechanical strength of equipment, i.e. lifting amount and weight of equipment have farthest been annotated portable notion.And employing foldover design.Not only that appurtenances are folding, also solved the folding problem of main bearing beam strut bar, take up an area of very little when making the utility model fold carrying.
Convenient for field application, be equipped with the high-quality cardan wheel, can move at the scene easily.Lifting power is synchronous dynamo, and can be best provide lifts required torsion.After equipment hoisting finished, its withdrawal is folding, and institute took up space few.
