Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.
Only those parts relevant to the embodiments of the present utility model are shown for convenience of description.
The combined drawing 1-4 shows, lift platform includes two sets of fork lifter plates around, and the fork lifter plate includes two backup pads 1 that middle part pivot is connected, fork lifter plate bottom is equipped with bottom plate 2, and the top is equipped with roof 3, fork lifter plate one end rotates with bottom plate 2, roof 3 respectively and is connected, and the other end rotates and is equipped with a pair of gyro wheel 4, bottom plate 2, roof 3 correspond gyro wheel 4 and all are equipped with a pair of slide 5, gyro wheel 4 slidable mounting is in corresponding slide 5, be equipped with the drive arrangement who is used for driving roof 3 to go up and down on bottom plate 2, connect reversing lever 6 respectively between two sets of fork lifter plates, fork lifter plate is different from reversing lever one side and has installation pole 7 in addition, installation pole both ends sliding contact is to the border of fork lifter plate, drive arrangement includes rolling wheel 8, be equipped with many belts 9 along length direction on the rolling wheel, the belt 9 is all walked around reversing lever 6 after fixing on installation pole 7, still be equipped with mounting bracket 10 on the bottom plate 2, the belt is passed mounting bracket 10 on the mounting bracket corresponds every belt and all is equipped with encoder 11 on the mounting bracket, drive arrangement still is equipped with the drive arrangement that is used for rotating 12.
In this structure, two backup pads are through rotating the fork lifter that connects into intercrossing, and drive arrangement drives the angle of changing between the backup pad of two crisscross plays the purpose of adjustment roof height.
When the roof needs to rise, driving motor drive reel rotates for the reel begins the rolling belt, and at this moment, the backup pad that is located fork lifter inboard rotates backward under the effect of belt, and the backup pad that is located the fork lifter outside slides forward in the slide under the effect of gyro wheel simultaneously, and then rotates in opposite directions with the backup pad of group, makes the roof rise.
