Self-supporting variable-frequency pulling winch

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 ...

Problems solved by technology

However, the relocation of fully mechanized mining equipment and the handling of other types of electromechanical equipment require frequent movement of the position of the winch. This fixing method is not only time-consuming and laborious, but also has a large potential safety hazard due to the lack of single pressure control and detection functions, which affects the fully mechanized mining. Retraction efficiency and safety guarantee of working face
