Auxiliary articles such as a sound (44), a temperature and humidity sensor (41), a smoke sensor (42), an audible and visual alarm (43) and the like can be installed at proper positions on the maintenance platform as required, and the auxiliary articles are shown in fig. 4.

The invention has the following steps:

after the handle (8) is held by two hands, the thumb of the right hand presses the button (13), the electronic lock (15) is opened, and the shell (5) is held by hands to rotate and put down. Because the rotation center of the extension ladder (17) is not coincident with the rotation center of the maintenance platform support frame (3), the support frame (3) generates relative motion with the extension ladder (17) when rotating. In order to ensure that the support frame (3) rotates smoothly, the clamp (9) is rotationally connected with the support frame (3), and the clamp (9), the extension ladder (17), the support frame (3) and the fixing frame (2) form a group of crank block mechanisms, and the principle of the crank block mechanisms is shown in figure 4.

After the maintenance platform is put down, the quick release (24) of the clamp (9) is opened, the distance between the clamping plate (25) and the clamping head (27) is increased under the action of spring force, and therefore the cross beam of the extension ladder (17) is loosened. The extension ladder (17) is pushed upwards, then rotates outwards and is pulled down to the ground. The retraction operation is the reverse of the drop.

Finally, the support frame (3) and the fixing piece on the support frame can rotate relative to the fixing frame (2) around the hinge shaft, the clamp (9) can rotate relative to the support frame (3) around the hinge shaft, the extension ladder (17) can rotate relative to the fixing frame around the axis of the inner hole of the extension ladder fixing head (19), and the fixing frame (2) is fixed on the portal frame (40). The effect of the service platform in final use is shown in figure 7.

The invention has simple structure, safety, reliability and convenient operation. Through fixing the rotary connection point of the extension ladder (17) on the fixed frame (2) instead of the support frame (3), the requirement on the total height of the extension ladder is met, and the height of a maintenance platform handle (8) is effectively reduced. The maintenance platform can be directly operated by hands by maintenance personnel without the help of a pull rod. More auxiliary items can thus be integrated on the service platform without fear of being too heavy to cause operational difficulties. Anchor clamps (9) pass through hinge swivelling joint with support frame (3), guarantee that electronic lock (15) open back maintenance platform soon and rotate smoothly. The illuminating lamp (6), the handle (8) and the button (13) are sunk into the shell (5), and simultaneously, the screw and the nut for connection are covered, so that the lower surface is a plane.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.
