The GIS dust cover can conveniently adapt to sites of different heights and terrains with different heights for construction by using the two layers of the frames and a handheld lifting mechanism, and is convenient to disassemble and assemble. In addition, stability of a ceiling body is further improved because of usage of supporting hooves of the frames.

Description

A GIS dustproof cover with a height-adjustable ceiling

technical field

The invention relates to a GIS dustproof cover with a height-adjustable ceiling.

Background technique

    The existing GIS installation shed ceiling device is usually composed of a frame, a rain-shielding cloth (rain-shielding plate), a connecting device, etc. When installing the ceiling, it is necessary to combine multiple small parts before installing, which is troublesome and time-consuming , It is not conducive to the construction needs of fast installation. At present, the specifications and sizes of GIS on the market are slightly different, such as height and width. At the same time, the space of the GIS installation site is limited. It is used for construction on sites with different heights.

Contents of the invention

The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a quick-installation GIS dustproof cover that can realize a height-adjustable ceiling.

In order to solve the above technical problems, the technical solution of the present invention is: a GIS dustproof cover with a height-adjustable ceiling, including a wall and a ceiling, characterized in that the wall includes an outer frame, and the outer layer A liftable inner frame is set inside the frame, a ceiling is fixed on the inner frame, a hoof support frame that can be opened to both sides is provided at the bottom of the outer frame, and a hoof support frame is provided in the middle of the hoof support frame. There are supporting feet that extend downwards.

Further, the hoof support frame includes two push rods hinged on the outside of the bottom of the outer frame.

Further, pulleys are provided on both sides of the inner frame towards the inner wall of the outer frame, a handle is provided on the outer frame, and a gear is provided at the front end of the rotating shaft in the center of the handle, and the gear drives the outer frame The inner rack goes up, the top of the rack is provided with a push rod extending to the inner side of the outer frame, and the two sides of the inner frame are provided with flanges, and the flanges abut against the push rod.

Further, guide wheels are provided on the top of the outer frame.

Further, moving wheels are provided at the bottom of the outer frame, and guide rails laid on the ground are provided under the moving wheels.

Compared with the prior art, the present invention has the following beneficial effects: the utility model utilizes a double-layer frame and a hand-operated lifting mechanism to make the GIS dust cover conveniently adapt to different heights and unequal heights for construction and use, and it can be dismantled It is easy to install, and the use of the supporting feet of the frame further improves the stability of the shed.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 5, a GIS dustproof cover with a height-adjustable ceiling in the utility model includes a wall and a ceiling. It is characterized in that the wall includes an outer frame 10, and the outer layer A liftable inner frame 20 is set inside the frame, a ceiling 30 is fixed on the inner frame 20, and a hoof support frame 110 that can be opened to both sides is provided at the bottom of the outer frame 10. The middle part of the foot support frame is provided with a support foot 111 extending downward. The hoof support frame 110 is two push rods hinged on the outer side of the bottom of the outer frame, and two groups are arranged symmetrically on both sides of each outer frame 10 .

The inner frame 20 is provided with pulleys 210 towards both sides of the inner wall of the outer frame, and the outer frame is provided with a rocking handle 120, and the front end of the rotating shaft in the center of the rocking handle is provided with a gear, and the gear drives the inner side of the outer frame. The rack goes up, and the top of the rack is provided with a push rod extending to the inner side of the outer frame, and flanges are provided on both sides of the inner frame, and the flanges abut against the push rod.

The top of the outer frame 10 is provided with guide wheels 130 , the bottom is provided with moving wheels 140 , and below the moving wheels 140 is provided with guide rails 40 laid on the ground.

When in use, according to the actual situation of the construction site, select a guide rail 40 with a suitable length and place it on both sides of the GIS equipment. An inner layer frame 20 is packed in the outer layer frame 10, and its position is adjusted to ensure that the guide wheels 130 on the outer layer frame 10 are attached to the side walls of the inner layer frame, and the pulleys 210 on both sides of the inner layer frame 20 should be aligned with the The inner side of the outer layer frame 10 is bonded. After the combined frame is completed, the moving wheel 140 at the bottom of the outer frame 10 is packed into the concave groove of the guide rail 40, and the metal hoof support frame 110 is opened at the same time, the support feet 111 are put down, and the opening degree of the hoof support frame 110 is adjusted to make the combined frame Stand stably on the guide rail 40, and follow the same steps to install the combination frame on the other side of the GIS to complete the installation of the shed.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
