Example Embodiment

[0025] The specific implementation of the patent of the present invention will be further described with reference to the accompanying drawings.

[0026] As shown in the figure, the self-supporting variable frequency traction winch mainly includes an integral chassis 1, a four-pillar cylinder 2, a four-link mechanism 3, an integral ceiling 4, a heightening seat 5, an electrical control box 6, a twisting mill 7, a cycloid 8. Gearbox 9, multi-disc wet brake 10, variable frequency motor 11 and related connecting pins and bolts. The winch realizes the integrated design of self-supporting fixing and traction functions. The twisting and unwinding of the cable can be frequency-converted and speed-regulated. Each action and function can be operated by remote control. The electrical system has automatic parameter detection and protection functions.

[0027] Specifically, the self-supporting variable frequency traction winch is mainly composed of a supporting device, a transmission system, a...

Abstract

The invention belongs to the technical field of mining equipment, and particularly relates to a self-supporting variable-frequency pulling winch. The self-supporting variable-frequency pulling winch comprises a supporting device, a transmission system, an electric control system and a hydraulic system, and the supporting device and the transmission system are controlled by the electric control system and the hydraulic system; and the supporting device comprises an integral chassis arranged on the lower portion and an integral ceiling arranged on the upper portion, a heightening base is arranged over the integral ceiling, and the integral chassis, the integral ceiling and the heightening base arranged over the integral ceiling are connected together through four stand column oil cylinders and four connecting rod mechanisms. According to the self-supporting variable-frequency pulling winch, the retracement comprehensive efficiency of fully mechanized coal mining face equipment can be significantly improved, the security coefficient is high, the labor intensity is low, existing congeneric products can be completely replaced, and the good market popularization prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to a self-supporting frequency conversion traction winch. Background technique [0002] The safety and efficiency of the support withdrawal is the key to the withdrawal of the fully mechanized mining face, and the winch is the key equipment for the support withdrawal, so it is of great significance to optimize and improve its working performance. [0003] At present, the support traction winch used for the retraction of fully-mechanized coal mining face is an overall longitudinal frame structure without supporting device itself, and needs to be ground anchored or modified to be used with a single pillar. Restricted by on-site working conditions, the fully mechanized mining face usually supports the drawworks in a solid way of six single pieces with four pressures and two closures. However, the relocation of fully mechanized mining equipment and the handling of ...
