Description

a safety platform

technical field

The utility model relates to a power system maintenance equipment, in particular to a safety climbing platform.

Background technique

When carrying out climbing operations, it is often necessary to use climbing ladders or various climbing platforms. The former is easy to move, but when it is used, it is restricted by pedal electrics, which brings a lot of inconvenience to climbing operations. The latter is more convenient when carrying out climbing operations, especially the movable equal-height platform is more convenient in actual use and has a wider applicable surface. However, in some cases where the height of the working platform needs to be increased, the way of manually lapping the movable platen is often adopted, which is very inconvenient and has potential safety hazards in the on-site operation. In addition, this kind of climbing platform is only suitable for close-range use. For the convenience of movement, it is often necessary to assemble casters at the bottom of the mobile climbing platform, but after the foot brake is assembled, the contact surface is reduced, the stability is insufficient and the platform body is prone to slip, and the anti-skid is not reliable.

After searching, the application number: 201320209993.4, the patent name: a multifunctional climbing platform, which includes a first-level climbing platform and a second-level climbing platform, and the first-level climbing platform and the second-level climbing platform are integrated structures. There is a push-pull tray on the secondary climbing platform. The first-level climbing platform and the second-level climbing platform are all composed of a support frame and a work table, and insulating non-slip rubber is laid on their work table. A pair of rollers are provided on the outside of the support frame bottom of the secondary climbing platform. The climbing platform is more convenient than traditional products when moving its position, and can be dragged and walked. On the one hand, it still uses a point-contact method with the ground, which is severely worn after long-term use, and the anti-skid effect is not good. On the other hand, the improved platform is supported by a general support frame, which cannot well meet the needs of operations at different heights. The whole product is inconvenient to store and take up, and occupies a large volume.
