X-ray ground-track trolley transmission equipment

Abstract

The invention relates to the field of transmission equipment, and discloses X-ray ground-track trolley transmission equipment. The X-ray ground-track trolley transmission equipment comprises a machineframe, a sliding block assembly which is arranged on a trolley and used for driving the trolley to slide in the length direction of the machine frame, magnets fixed to the sliding block assembly, anelectromagnetic attracting board which is arranged on the machine frame and used for attracting or repelling the magnets, a motor base arranged on the machine frame, a motor arranged on the motor base, an electromagnetic clutch arranged on a main shaft of the motor in a sleeving mode, a driving wheel fixed to a driving disc of the electromagnetic clutch, a synchronous belt connected with the driving wheel, a driven wheel connected with the synchronous belt, a supporting frame which is arranged on the machine frame and used for driven wheel placement, a main control unit, and a first limiting switch and a second limiting switch which are arranged at the two ends of the machine frame in an opposite mode and used for sensing the trolley. Compared with the prior art, the X-ray ground-track trolley transmission equipment has the advantages that the equipment can not only automatically run, but also be operated and run manually, starting and stopping are more smooth and steady, and braking force is high.

Description

technical field [0001] The invention relates to a transmission device, in particular to a transmission device for an X-ray ground rail trolley. Background technique [0002] Medical X-ray equipment is a device that generates and controls X-rays for human tissue radiation inspection and radiation therapy. This type of equipment has an X-ray generating device. At present, the X-ray generating device is placed On the ground rail trolley, ray scanning is performed by moving the trolley. The existing ground rail trolley transmission mechanism is driven by a DC24V DC geared motor through a synchronous belt, and the position is controlled by a potentiometer. There is no switching between manual and electric modes, only electric mode, low movement position accuracy, slow speed, and poor start-stop stability , The low braking force mainly depends on the damping produced by the reducer. Contents of the invention [0003] The purpose of the present invention is to provide a transmi...

Problems solved by technology

The existing ground rail trolley transmission mechanism is driven by a DC24V DC geared motor through a synchronous belt, and the position is controlled by a potentiometer. There is no switching between manual and electric modes, only the electric mode, and the movement position accuracy is low, the speed is slow, and the start and stop stability is poor. The low braking force mainly depends on the damping produced by the reducer
