Process and tool for winding electromagnetic brake coil of boring winch

Abstract

The invention relates to a process and a tool for winding an electromagnetic brake coil of a boring winch, which are characterized in that a connecting flange is connected with a winding machine via a taper hole and a top thread; an internal pressure plate is fixed to the connecting flange via threaded connection; a winding mould is fixedly confected with the internal pressure plate via a screw thread; an external pressure plate is fixedly connected with the winding mould via a fixing bolt; and the external pressure plate and the internal pressure plate of the winding mould are provided with process grooves. The process for winding the coil comprises the following steps of: selecting and inspecting a wire gauge; winding the coil, reshaping the coil, performing thermal shrinkage and insulation wrapping on the coil, dipping the coil in paint, drying the dipped coil, performing the second thermal shrinkage and insulation wrapping on the dried coil, dipping the coil in paint for the second time, drying the dipped coil for the second time, molding the coil, detecting technical parameters and obtaining a product. The process uses a combined mould structure on the aspect of mould design and can replace different mandrels according to different specifications of the coil so as to realize the winding of the coil and overcome the key technical difficulty of the assembly and disassembly of the coil from the mould in the process of winding the coil. Therefore, the process and the tool for winding the electromagnetic brake coil of the boring winch fully realize the manufacturing and use of various electromagnetic brake coils of the boring winch.

Description

technical field [0001] The invention relates to a coil winding process and a tool, and is particularly suitable for the coil winding process and tool of various types of drilling rig drawworks electromagnetic brake coils for oil drilling. technical background [0002] The core component of the electromagnetic brake is the coil, and the main reason for the loss of the function of the electromagnetic brake is the burning of the coil. Coil burnout is mainly due to the unstable voltage during the use of the equipment, the actual current is too large, and the voltage is too high to cause the coil burnout; secondly, due to the influence of the environment and operation, the coil cannot be isolated and protected when cleaning the equipment, so that the coil is damp. Also burns out the coil. Technically, because the purchased coils have substandard insulation, insufficient mechanical strength, and magnetic flux leakage due to excessive roundness, the service life of the coils is re...

AI Technical Summary

Problems solved by technology

[0004] One of the purposes of the present invention is to design an electromagnetic brake coil for drilling rig drawworks in view of the current situation that the electromagnetic brake coil is easy to be burned during use, the coil replacement cost is too high during overhaul, and the supply cycle is not reliable, which restricts equipment repair. Winding process to effectively reduce equipment repair costs, maximize equipment repair timeliness, and improve reliability

[0005] The second object of the present invention is to provide a winding tool for the electromagnetic brake coil of the drilling rig winch. Reliable Guarantee Restricts Equipment Repair
