Scissors fork type expansion device for suspended trolley

Abstract

The invention discloses a scissors fork type expansion device for a suspended trolley. The scissors fork type expansion device comprises a mounting base. A driving component is fixedly connected to the mounting base. The driving component is rotatably provided with driving shafts. The driving shafts are connected with driving arms. The free ends of the driving arms are hinged to scissors fork assemblies. The driving shafts rotate to drive the driving arms to swing. The driving arms drive the scissors fork assemblies to stretch and retract. The driving component comprises a lead screw assemblyand a motor. The driving shafts are fixedly connected with the swing arms. The driving component of the scissors fork type expansion device is realized by combining the motor and the lead screw assembly. The motor drives a lead screw to do linear reciprocating motion, drives the swing arms to swing through linear motion of a lead screw nut and then drives scissors forks to stretch and retract. Thelead screw assembly can obtain larger torque than direct driving of the motor. The scissors fork type expansion device can carry heavier objects. Moreover, compared with a reduction motor, a servo motor or and oil hydraulic and other power components, the scissors fork type expansion device is small in size, and the requirement of the suspended trolley for the running environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of logistics transportation, and in particular relates to a scissors and forks telescopic device for hanging trolleys. Background technique [0002] The suspension trolley is also called the running trolley or the EMS trolley, which belongs to the EMS (Electrical Monorail System) conveying system (aerial suspension monorail conveying system). It is a mechanical device that sets a track in the air and is hoisted on the track and can walk along the track. At present, it is more and more widely used in the logistics industry and on-site distribution industries. With the background of Industry 4.0, these automation systems have become more and more popular among manufacturers. [0003] In the suspension trolleys in the prior art, most of the shelves used for hoisting goods use a combination of steel ropes and hooks or a shelf platform to hang goods.

Problems solved by technology

[0003] In the suspension trolleys in the prior art, most of the shelves used for hoisting goods use a combination of steel ropes and hooks or a shelf platform to hang goods. It needs to obtain enough lifting torque, and it is driven by a bulky geared motor or oil cylinder. The huge volume brings great trouble to the operation and installation of the suspension trolley.
