Example Embodiment

[0011] Hereinafter, the present invention will be described in more detail with examples in conjunction with the accompanying drawings:

[0012] Combine Figure 1~2 , The invention consists of a car body 1, a lift 2, and a lift installation block 3. The car body 1 is fixedly connected by square aluminum and is divided into two layers. The top floor is equipped with a mounting support frame 8, a handrail 4, and a support frame 8 and bolt holes 5 for installing and fixing operating equipment. There is a lift mounting bracket 7 on the upper side of the bottom layer. The lift mounting block 3 is fixed to the mounting frame 7 by welding. The lift mounting block 3 has bolt holes 9 whose position and size correspond to the mounting holes at the bottom of the lift 2. The lift 2 is connected by bolts The way is fixed on the elevator installation block 3. A circular hole is opened in the center of the elevator mounting block 3 for the lifting screw 11 of the elevator 2 to pass through. ...

Abstract

The invention provides a movable lifting platform for a centrifugal fan. The movable lifting platform comprises a vehicle body and worm gear screw lifting machines. The vehicle body comprises a top layer and a bottom layer, the top layer and the bottom layer are vertically connected with each other. A supporting frame used for mounting the centrifugal fan is fixed to the top layer. Lifting machine mounting supports are fixed on both of the opposite faces of the bottom layer. The worm gear screw lifting machines are mounted at the front end and the rear end of each lifting machine mounting support through respective corresponding lifting machine mounting blocks. The two lifting machine mounting support are provided with holes for the screws of the four worm gear screw lifting machines to ascend and descend. A circular supporting foot pad is arranged on the bottom of the screw of each worm gear screw lifting machine. According to the movable lifting platform for the centrifugal fan, the working stability of the centrifugal fan is improved, when the centrifugal fan works under the working conditions such as the uneven ground, operation devices have certain levelness demands, a large adjusting range can be provided through the design of four corner lifting, and adjustment on the levelness of the platform is convenient to carry out.

Description

technical field [0001] The invention relates to an experimental auxiliary device, specifically a lifting device. Background technique [0002] Under laboratory conditions, small centrifugal fans are often used as power sources for wind tunnel systems. In order to realize a centrifugal fan that can be connected to multiple experimental sections or a series-parallel arrangement of multiple small fans, it is often necessary to move the fan equipment and adjust the fan The height of the center is adjusted, therefore, a lifting device that can solve the problem of fan movement under laboratory conditions is required. [0003] Present movable lifting platforms are generally provided with a lifting function by a leading screw or a hydraulic device, and wheels are installed at its bottom to facilitate movement. However, when it is necessary to install equipment with high stability requirements such as fans on the lifting platform, the traditional type of lifting platform generally ...
