The invention provides a well repair platform which comprises a platform body and a base. The platform body is in the shape of a rectangular plate and is arranged on the base, two ends of the platform body respectively convexly extend away from the center of the platform body to form arc-shaped ends, and the circle centers of the edges of the arc-shaped ends coincide with the center of the platform body. The well repair platform has the advantages that the arc-shaped ends are arranged at the two ends of the platform body, the circle centers of the arc-shaped ends coincides with the center of the platform body, accordingly, the axes of ramps and anchor ways and the central axis of the platform body can be assuredly positioned in the same vertical plane when the ramps and the anchor ways are about to be constructed no matter where the ramps and the anchor ways are constructed at the arc-shaped ends, the ramps and the anchor ways can move along the arc-shaped ends until the ramps and the anchor ways are free of constraints of other surrounding structures if the ramps and the anchor ways cannot be straightly constructed due to place constraints of a certain position of the corresponding arc-shaped end, the ramps, the anchor ways and the platform body can be assuredly straightly constructed, and construction requirements can be met.

The invention relates to a suspension device and a maintenance device and belongs to the technical field of safety devices for aloft work of electric equipment. The suspension device comprises a baseplate, a support frame, a suspension bracket and a lifting device, wherein the baseplate is detachably connected with one end of the support frame; the suspension bracket is detachably connected with the other end of the support frame; both the support frame and the suspension bracket are adjustable brackets; a first adjusting switch is arranged on the support frame; a second adjusting switch is arranged on the suspension bracket; the suspension bracket is detachably connected with the lifting device; a holding region for holding a lifted object is arranged on the baseplate; a push handle is arranged on one side of the baseplate; the first adjusting switch is used for adjusting the length of the support frame; and the second adjusting switch is used for adjusting the length of the suspension bracket. The suspension device is very convenient to transport and carry, and can meet different operation requirements by adjusting the lengths of the support frame and the suspension bracket.

Suspension device and maintenance device

The invention discloses a movable transport frame for maintaining of power generating equipment. The movable transport frame comprises a bottom frame. Support plates are arranged on the two sides of the bottom frame. A connecting frame rod is matched between the tops of the two support plates. First screws are matched between the connecting frame rod and the support plates. L-shaped supporting grooves are formed in the faces of the support plates. A groove is formed in the tops of the supporting grooves. A suspension rod is matched in the supporting grooves. A carriage is arranged on the top of the bottom frame. A hydraulic cylinder is arranged on the top of the carriage and provided with two parallel output ends, and the output ends abut against the suspension rod. When the movable transport frame is used, the suspension rod can be lifted through assistance of hydraulic oil, lifting of the power generating equipment is finished, then, the suspension rod is matched in the groove by moving the carriage, and the hydraulic oil can be recycled after matching is finished. The supporting state does not need to be kept all the time, using is safer, and meanwhile the movable transport frame is small in size and convenient to move.

The invention discloses a hoisting device for maintaining of power generating equipment. The hoisting device comprises a base. Two inserting grooves are symmetrically formed in the top of the base. Support plates are arranged in the inserting grooves. A hydraulic device is arranged on the top of the base. Movable grooves are formed in the faces of the support plates. A hydraulic output rod connected with the hydraulic device is matched in the movable grooves. A supporting base is arranged on the top of the hydraulic output rod. A second screw is matched between the supporting base and the hydraulic output rod. A suspension rod is arranged in the movable grooves and matched on the supporting base. The suspension rod is matched with a steel wire hanging rope. The hoisting device is small in size, and when routine repairing and maintaining need to be carried out on a power generator, only the hoisting device needs to be pushed into a machine room; the power generator can be hoisted through the steel wire hanging rope, dismounting and maintaining are convenient, and meanwhile later assembling is convenient; and operation is easy and convenient, and using cost is low.
