Bucket lifting type mixing plant aggregate lifting system

Abstract

The invention relates to a bucket lifting type mixing plant aggregate lifting system. The bucket lifting type mixing plant aggregate lifting system comprises a control system, an aggregate batching system, a conveying system and an aggregate lifting system; the aggregate lifting system comprises a lifting bucket, a lifting track and a winch, and the lifting track is arranged at a vertical angle to the ground; an upper limit switch for triggering the winch to decelerate / stop is arranged at a certain height position on the upper part of the lifting track, a lower limit switch is arranged at a low position of the lifting track, and a limit switch which is matched with a touch rod arranged on the lifting bucket to trigger the winch to stop is further arranged above the upper limit switch; and a weight sensor is further arranged at the connecting position of a rope and the winch, the weight sensor is used for detecting the weight of the lifting bucket and sending a weighing value to a control system, and the control system controls starting and stopping of the winch according to the weighing value.

Description

technical field [0001] The invention relates to an aggregate lifting system of a bucket-lift mixing station, which belongs to the technical field of concrete production equipment. Background technique [0002] Concrete mixing plants in the concrete market are now widely used, and concrete mixing plants are divided into belt conveyor type and bucket lift type according to the feeding method of aggregate. The technical development of bucket-lifted mixing plants is earlier than that of belt-conveyed mixing plants. Small bucket-lifted mixing plants have the advantages of small footprint, flexible installation, and convenient movement, and are widely used. However, the technical level of large and medium-sized bucket-lifted mixing plants And the number of applications is relatively low, mainly because of the large and medium-sized bucket-lifted mixing plant hoisting motor power, heavy load, long track, there are the following problems in the process of use: (1) The traditional bu...

The technical development of bucket-lifted mixing plants is earlier than that of belt-conveyed mixing plants. Small bucket-lifted mixing plants have the advantages of small footprint, flexible installation, and convenient movement, and are widely used. However, the technical level of large and medium-sized bucket-lifted mixing plants And the number of applications is relatively low, mainly because of the large and medium-sized bucket-lifted mixing plant hoisting motor power, heavy load, long track, there are the following problems in the process of use: (1) The traditional bucket-lifted mixing plant is single The traditional upper and lower limits are used to set the travel switch to control the start and stop of the lifting bucket. The limit switch itself has a high failure rate. There is a rotary encoder on the rotating shaft of the lifting reel, but the instability and high failure rate of the stroke of the travel switch and the rotary encoder in this structural form make the user still unable to eliminate concerns about the structure (2) Inclined track The wear-resistant type is not enough and easy to wear, it is difficult to replace after wear, and there are safety hazards in maintenance. (3) The hoisting bucket of the traditional bucket-lifting mixing plant is lifted by a single rope. During the lifting and lowering process, the hoisting rope is prone to breakage and the hoisting bucket falls fall, causing major safety accidents (4) and the lifting time of the existing bucket lift mixing plant is long, and the production efficiency is low
