Problems solved by technology

[0005] 1 Failure to obtain the current winding material length of the hoist accurately and with a small error
[0006] 2 Failure to measure the winding length of the hoist in real time
[0007] 3 Existing measurement methods affect normal production during the measurement process, or cause mechanical deformation damage to the winding material
[0008] 4 When using the hoist to measure the winding length of the material, the influence of the increasing radius of the hoist after the material is wound is ignored, and it is used as a constant value to calculate the winding length of the hoist, resulting in large error

Embodiment Construction

[0056] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0057] see figure 1 , the invention of the winding length automatic measuring system of the stacked winding object of the hoist includes a rotary encoder 1, an input module, an intelligent module and a display module.

[0058] The rotary encoder 1 is used to collect the angular displacement θ of the hoist 2 relative to the initial position. The rotary encoder 1 can be a magnetic encoder or a photoelectric encoder, and is connected to the shaft of the hoist 2 through a flange or a coupling, or a motor with a built-in encoder can be selected to drive the hoist 2 . In order to meet the function of measuring the number of turns, an incremental encoder or a multi-turn absolute encoder is required.

[0059] The input module includes an input keyboard through which relevant parameters are pre-input to the system, and these parameters include the in...

Abstract

The invention discloses a system and a method for automatically metering the winding length of a laminated winding object of a winch. The system comprises a rotary encoder, an input module, an intelligent module and a display module, wherein the rotary encoder is used for collecting the angular displacement of the winch relative to the initial position; the input module is used for inputting the initial winding radius r and the winding length 1 corresponded when the winch performs winding by N rings; the intelligent module is used for receiving and storing the information of the rotary encoder and the information of the input module, and calculating the current winding length of the winch and outputting the winding length to the display module; the display module is used for displaying the system parameter information and the calculating result. The system can calculate the current winding length of the winding object real-timely, conveniently, quickly and accurately, and the influence on the work process of the winch during the metering process is not caused.

Description

technical field [0001] The invention relates to a length measurement system, in particular to an automatic measurement system and method for the winding length of stacked winding objects of a hoist. Background technique [0002] In engineering practice, the hoist is used in a wide range of occasions. It is mainly used in the following occasions, retracting and unwinding the steel wire rope of the crane or hydraulic car hoist, discharging the wires of the pay-off car, retracting and unwinding the rope of the high-altitude fall arrester, and the work of the well-drilling hoist. Lifting and unloading of workers, and winding of factory paper, yarn, cloth, film, etc. Wherein, some of the rolled objects belong to the stacked rolled objects, that is, the rolled objects are rolled outwards in a stacked manner one by one, for example, the winding of agricultural spraying pipes. However, in the prior art, there is a lack of a set of convenient, fast and reliable detection methods for...
