Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1;

a safe working lifting platform for electric power overhaul comprises a folding frame 1, a base 2 is arranged at the bottom of the folding frame 1, a hydraulic cylinder 3 is arranged at one side of the base 2, in the using process, after the lifting platform is pushed to the overhaul ground, the base 2 is fixed, then the motor is started to drive the hydraulic cylinder 3 to jack upwards, thereby driving the folding frame 1 to stretch in the vertical direction, thereby improving the height, but the shape of the power equipment is irregular, and the equipment has a plurality of welding fulcrums which also need to be repaired regularly, if the nodes in the cracks in the equipment need to be repaired, because the occupied area of the lifting platform is larger, the lifting platform is not convenient to move in the narrow space for maintenance, therefore, after the height required by maintenance is increased, a worker still has a section distance from the maintenance node, if the worker cannot keep balance, the potential safety hazard is large during maintenance, and on the basis, the workbench 4 and the limiting assembly 5 are added.

As shown in fig. 1, 2, 3, 4;

in an alternative embodiment: the workbench 4 comprises a fixed frame 41, an inner plate 42 and a protective cover 43, the bottom of the fixed frame 41 is fixedly connected with the folding frame 1, the outer wall surface of the fixed frame 41 is slidably connected with the inner plate 42, and the top of the inner plate 42 is fixedly connected with the protective cover 43.

In this embodiment: after the fixing frame 41 is fixed to the folding leg 1, the inner plate 42 placed inside the fixing frame 41 can extend out of the fixing frame 41 by rotating the position limiting assembly 5, the outer surface of the fixing frame 41 is not smooth, and the bottom surface of the inner plate 42 contacts the fixing frame 41, so that when the position limiting assembly 5 does not work, the inner plate 42 cannot slide out of the fixing frame 41 due to failure of the position limiting assembly 5, and workers are injured due to sliding of the inner plate 42; on the other hand, when the workman is close overhauls the node, because inner panel 42 stretches at the angle that is most suitable for overhauing the node, so the workman can keep self balanced when overhauing, has reduced the potential safety hazard, and protection casing 43 sets up on inner panel 42, has avoided the risk that the workman falls.

It should be noted that: the fixing frame 41 has a concave frame structure, and the bottom of the fixing frame 41 is slidably connected to the bottom of the inner plate 42.

It should be understood that: the inner plate 42 has a "T" shaped configuration.

Further, the method comprises the following steps:

as shown in fig. 2, 3, 4;

in an alternative embodiment: the limiting assembly 5 comprises a rotating disc 51, a limiting ring 52, a rotating rod 53 and a sliding sleeve 54, the rotating rod 53 is fixedly connected to the bottom of the rotating disc 51, the limiting ring 52 is slidably connected to one side, close to the rotating disc 51, of the rotating rod 53, and the sliding sleeve 54 is arranged at the bottom of the rotating rod 53.

In this embodiment: firstly, the rotating disc 51 is rotated, so that the rotating rod 53 can rotate along with the rotating disc 51, the limiting ring 52 is fixed on the inner plate 42 for limiting, and the phenomenon that the rotating rod 53 deviates when stressed to cause that the gear 541 of the sliding sleeve 54 cannot slide in the direction of the rack 542 is avoided, so that the inner plate 42 blocks the fixed frame 41 and cannot slide out is avoided; and the gear 541 and the rack 542 of the sliding sleeve member 54 are engaged, that is, the inner plate 42 is limited, and a worker can adjust the inner plate 42 to a position most suitable for maintenance by rotating the rotating disc 51.

It should be noted that: the limiting assemblies 5 are arranged in two groups, and the two groups of limiting assemblies 5 are symmetrically arranged on two sides of the inner plate 42.

As shown in fig. 3 and 4:

with the above in mind: the sliding assembly 54 includes a gear 541 and a rack 542, the outer circumferential surface of the gear 541 is fixedly connected to the rotating rod 53, the gear 541 is engaged with the rack 542, one side of the rack 542 is fixedly connected to the fixing frame 41, two sides of the fixing frame 41 are both provided with grooves 55, and the rack 542 is fixedly connected to the inside of the groove 55.

In this embodiment: through mutually supporting of gear 541 and rack 542, thereby go on preventing the workman from falling to the inner panel 42 that stretches out, and when the volume of stretching out reached the biggest, the surface of gear 541 can support the recess 55 on the fixed frame 41, prevents because the whole inner panel 42 roll-off fixed frame 41 that the volume of stretching out too big leads to, causes accident disaster.

It should be noted that: the turn lever 53 does not contact the fixed frame 41 when the inner plate 42 is extended.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
