Description

Four-column type high-speed rail elevator with trolley mechanism

Technical Field

The utility model relates to a four-column type high-speed rail lifter with a cart mechanism, which is matched with a stacking conveyor.

Background

At present, in the field of manufacturing of two-wheelers, as three working procedures of welding, coating and assembly have economic beats, a common factory adopts a mode of temporarily storing a turnover area by arranging line edges or adopting WBS and PBS storage lines so as to enable each production link to be matched with the final assembly beat. At the moment of increasing land cost, how to increase the output value of unit land and increase the space utilization rate is emphasized by more and more enterprises. Therefore, the rail lifter used by the matched stacking type conveyor for spatial layout is adopted, the vertical layout of WBS lines or PBS lines can be efficiently realized by adopting the high-speed rail lifter, the space and the field waste caused by climbing of the traditional conveying line are saved, the workshop logistics channel is smoother, and the storage line layout is more stereoscopic.

The conventional track elevator generally comprises a main frame, a driving assembly, a lifting support, a lifting track and a counterweight assembly, wherein the lifting support can be arranged in the main frame in a vertical sliding manner, the lifting track is fixedly arranged at the upper end of the lifting support, a stopper and a backstop are arranged on the lifting track in a matched manner, the counterweight assembly can be arranged on the back surface of the main frame in a vertical sliding manner, the driving assembly is arranged at the upper end of the main frame, a lifting chain is arranged on a rotary chain wheel of the driving assembly, one end of the lifting chain is connected with the counterweight assembly, the other end of the lifting chain is connected with the lifting support, the stacking trolley is arranged on the track, and a workpiece is hung on the stacking trolley which is pushed to move on the track through a pushing head on a driving chain of the stacking conveyor.

When the track elevator is used, the driving assembly drives the lifting support, the lifting track, the stacking trolley on the lifting track and the workpiece hung on the stacking trolley to ascend together, and when the lifting support and the lifting track ascend to a set height, the two ends of the lifting track are in butt joint with the main track of the stacking conveyor, so that the stacking trolley on the lifting track and the workpiece on the stacking trolley can move onto the main track, and other stacking trolleys on the main track can also smoothly pass through the track elevator.

However, during production, the movement beats of the stacker trolley at the track lift may be affected, i.e. the efficiency of this part of the position becomes low.
