Problems solved by technology
In the spring and autumn maintenance and defect handling process, the maintenance personnel need to carry two special maintenance platforms corresponding to the knife switch model for maintenance work, which increases the labor intensity of the maintenance personnel and reduces the operating efficiency. At the same time, the special maintenance platform purchased The structural design is unreasonable, resulting in laborious installation and fixation of the platform, complicated operation, unstable fixation, and extremely poor safety
Since the GW7A-252DW knife switch is limited by the main knife arm of the operation phase, the special maintenance platform cannot be used on the operation phase.

Embodiment Construction
[0012] see figure 1 , 2 , the names of the main components are as follows: frame 1, fixed plate 2, hook leg 3, round pipe 4, bushing 5, operating handwheel 6, lead screw 7, forward buckle nut 8, reverse buckle nut 9, center positioning screw hole 10 , upper hook plate 11, lower hook plate 12, positive buckle transmission shaft 13, reverse buckle transmission shaft 14, conical surface 15, inclined plane 16, center positioning plate 17.
[0013] see figure 1 , 2 , the fast fixing device for the knife gate maintenance platform includes a frame 1, which is a cuboid composed of four round tubes 4 (or guide tubes); the frame 1 is vertically provided with fixed plates 2 and grooves for connecting the ladder legs of the maintenance platform at intervals. Made of steel with opposite notches. There are two pairs of hook legs 3 that slide relatively on the frame 1, forming four hook legs 3, the two on the left are connected, and the two on the right are connected. Each hook leg 3 is...

The invention relates to a quick fixing device for a knife-switch overhaul platform, and belongs to the field of electricity high voltage isolator serving tools. The quickly fixed device comprises a frame. Fixed plates are separately installed on the frame, which are used for connecting ladder legs of the maintenance platform. The frame is provided with two pairs of hook legs which are relatively sliding. When the device is in use, the four channel-shaped fixed plates of the frame are connected with the ladder legs of the maintenance platform through bolts. The four hook legs installed on the frame can be adjusted left and right to adapt to the disconnecting links of different models. The quickly fixed device has the advantages of being simple and convenient to operate, flexible in movement, firm in fixation, high in safety, wide in application, and time-saving . The problems that an original maintenance platform needs to be fixed through bolts in a multi-point mode which causes trouble, and the maintenance platform can not applied to the disconnecting links with different models, can be solved.
Description
[0001] technical field [0002] The invention relates to a fast fixing device for a knife gate maintenance platform, which belongs to the field of maintenance tooling for electric high-voltage isolating switches. Background technique [0003] In the prior art, the high-voltage isolating switch (or knife switch) is the most widely used high-voltage switchgear in the power system. Due to the high-voltage isolation switches with outdoor structures, most of them operate under relatively harsh conditions and are directly exposed to the atmospheric environment. Affected by the environment and climate conditions, there are generally poor contacts between the contacts and contacts during operation. 1. The contact is seriously burned, the contact finger spring is invalid, the pressure is not enough, the conductive tube is in poor contact with the moving contact, the contact finger is in poor contact with the static contact seat, the static contact seat is in poor contact with the wirin...
