Movable type reverse self-locking lift platform

Abstract

The invention discloses a movable type reverse self-locking lift platform. The platform comprises a transmission mechanism, a lift mechanism and a platform framework. The platform framework comprises an upper platform and a lower platform; the transmission mechanism comprises a direct current motor, a turbine reducer, four sets of driving piece stand columns, a driving piece installation plate, two sets of synchronous wheel driving wheels, two sets of synchronous belts, two sets of synchronous wheel driven wheels, two sets of ball screws, two sets of ball screw slide blocks, two sets of ball screw slide block installation seats, four sets of linear guide rail slide saddles and four sets of linear guide rails; and the lift mechanism comprises four sets of lift trestle combinations. According to the movable type reverse self-locking lift platform, the turbine reducer is arranged in the transmission mechanism, so that the lift platform can be reversely self-locked, and the upper platform is guaranteed to be locked firmly; the four sets of lift trestle combinations are driven by the same motor, so that movements of the four sets of lift trestle combinations are totally identical, and stable lift of the platform can be achieved; and a position sensor is configured on the direct current motor, and accordingly, the lift height of the platform can be accurately controlled.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a mobile reverse self-locking lifting platform. Background technique [0002] At present, there are many forms of lifting mechanisms, such as hydraulic, pneumatic and other driving methods. For some occasions that need to adjust the height accurately, the accuracy of lifting is very important, and the adjustment accuracy of hydraulic or pneumatic is often low, so hydraulic or pneumatic drive is not suitable for this occasion. For the lifting platform used by the hospital to withstand the free lifting of patients, its safety considerations are very important, so its reverse self-locking function must be taken into account in the mechanical design. Commonly used lifting platforms cannot meet the above requirements, so they are not suitable for use in this situation. Contents of the invention [0003] In view of the above problems, the present invention designs a mob...
