In this scheme, the link gear can ensure that the support columns 11 keep synchronous in the lifting process of the lifting platform 1, and the unstable phenomenon caused by the relative displacement between the support columns 11 is prevented.
Low height state:
When the lifting platform 1 is in the low-height state, all support columns 11 have been retracted into the lifting seat 2, or part of the support columns 11 still slide in the lifting platform 1. At this time, the distance between the lifting platform 1 and the electric power and electric equipment is relatively short, so that the overhauling personnel can conveniently perform short-distance inspection and maintenance work. Because the number of the support columns 11 is small or the support columns are not fully unfolded, the whole structure is compact, and the stability is relatively low. But the overall stability is still better due to the lower center of gravity of the platform. In this state, the service personnel can perform simple maintenance tasks such as tightening screws, cleaning surfaces, etc., using hand tools or small devices.
High state:
When the lifting platform 1 reaches the high state, all the support columns 11 have been unfolded and stably supported on the lifting platform 1. At this time, the distance between the lifting platform 1 and the electric power equipment is long, and an maintainer can stand on the platform to perform comprehensive inspection and maintenance work on the equipment. Because the number of the supporting columns 11 is large and the distribution is uniform, the overall structure stability is high, and the supporting columns can bear large load and external impact. In this state, the service personnel can use the large-sized equipment to perform complicated maintenance tasks such as replacement of parts, electrical testing, and the like.
Embodiment one working platform in low height
In a low-height state, the height of the lifting platform 1 is set to be about 3 meters, and the lifting platform is suitable for overhauling the ground or low-level power and electric equipment. At this time, all the support columns 11 have been fully unfolded and stably supported on the elevating platform 1.
The structural connection mode is as follows:
the support column 11 is connected with the lifting platform 1 through the embedded groove 3, and the design of the embedded groove 3 enables the support column 11 to be quickly and accurately inserted and fixed on the lifting platform 1.
Second embodiment working platform in high State
Under the high state, the height of the lifting platform 1 can reach more than 10 meters, and the lifting platform is suitable for overhauling high-rise electric power equipment. At this time, all the support columns 11 have been unfolded and stably supported on the elevating platform 1, forming a stable working platform.
The structural connection mode is as follows:
the supporting column 11 is connected with the lifting platform 1 through the embedded groove 3, similar to the low height state.
In order to ensure the stability of the support columns 11 in the high state, the inner end of each support column 11 is connected with the spring through the positioning gear 19 and the inner tooth groove 20, so that the support columns 11 are conveniently and rapidly clamped and embedded to be connected, and the connection stability is ensured.
Working principle:
when an maintainer needs to enter a working area in a low-height state or a high-height state, the maintainer enters the working area through a safety door at the edge of the platform, and lifts the lifting platform 1 to a designated height to start maintenance work.
In the working process, if the height or the position of the platform needs to be adjusted, an maintainer can operate the lifting and the moving of the platform through the control device.
After the work is completed, the maintenance personnel can lower the platform back to the initial position through the control device, so that the subsequent work or storage is convenient.
When the lifting platform is used, the linkage ring 10 and the arc-shaped block 16 are moved by the linkage spring 17, after the corresponding support column 11 is moved out along the lower opening of the outer end of each group of embedded grooves 3, the projection 14 and the groove 12 can be quickly combined with each other by the linkage spring 17 under the limit of the support column 11 without the linkage toothed ring 7 and the positioning gear 19, so that the lifting platform 1 is supported, when the lifting platform 1 is lifted to a certain height to stop, the stacking between the support columns 11 can be well supported and positioned by the linkage spring 17, in the process, the limit between the linkage toothed ring 7 and the positioning gear 19 and the linkage toothed groove 6 and the internal toothed groove 20 is realized by the internal bending structure of the embedded grooves 3, and the structural limitation of the lifting platform 1 is realized;
The linkage toothed ring 7 connected with the outer end of the linkage shaft 8 is connected with the linkage toothed groove 6, the support columns 11 are connected with the inner toothed groove 20 through the positioning gears 19, when a plurality of support columns 11 move in the inner embedded groove 3, the linkage spring 17 can be ensured to be in a stretched state, and when the positioning gears 19 outside the support columns 11 leave the inner toothed groove 20 and the linkage toothed ring 7 of one group at the upper end leaves the linkage toothed groove 6, the convex blocks 14 of the corresponding two groups of support columns 11 are correspondingly clamped and contacted with the grooves 12;
When the lifting platform 1 moves downwards, the tail end of each supporting column 11 is connected to the lifting structure, each supporting column 11 is recovered, and meanwhile, each corresponding group of supporting columns 11 is blocked by the silica gel ring 21 until the connecting shaft in the group of supporting columns 11 at the upper end moves to the uppermost end along the notch 13 in the convex block 14 (at the moment, the linkage spring 17 stretches to the maximum), at the moment, the positioning gear 19 at the outer end of the group of supporting columns 11 is clamped into the inner tooth groove 20 through the open groove 22, and the supporting columns 11 between the two groups can conveniently move in the inner embedding groove 3 through the structure.
