Problems solved by technology

[0003] Because the existing scraper machine is connected with the push cross head of the bracket through the pushing ear on the middle groove, therefore, in the process of pushing the bracket, due to the change of the positional relationship between the bracket and the scraper machine, it cannot be guaranteed The relative parallelism between the two will lead to one-sided force on the push ear on the middle groove, which will deform or break the push ear, resulting in a decrease in the efficiency of the working surface or stopping the replacement of damaged parts

Abstract

The invention discloses a support limiting device and method for a middle groove of a scraper machine. The support limiting device comprises a limiting mechanism, the limiting mechanism is arranged onthe middle groove and is opposite to a base of the support, and the limiting mechanism is used for limiting and the moving range of the base below the middle groove, so that the middle groove is keptparallel to the base. According to the support limiting device and method, the limiting mechanism is arranged on the middle groove, the moving range of the base below the middle groove is limited, sothat the middle groove and the base are kept parallel when the support is pushed, and then the support is kept parallel to the scraper machine. Meanwhile, the situation that a pushing lug deforms oris broken due to single side stress is avoided, and when the accurate relative positions of the support and the scraper machine are guaranteed, the damage frequency of a cross head connected with thepushing lug on the support is reduced; and therefore the use efficiency of working face fully-mechanized coal mining equipment can be improved through the support limiting device, and the pushing lugand the cross head can be prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a bracket limiting device and a bracket limiting method for a slot in the middle of a scraper machine. Background technique [0002] At present, the mining of fully mechanized mining faces has been paid more and more attention by coal mining enterprises. In order to effectively mine and better adapt to the high-efficiency use requirements of fully mechanized mining face conditions, attention should be paid to the support and scraping The relative position relationship between the triggers is to ensure the horizontal setting between the bracket and the scraper, and when the relative position between the bracket and the scraper changes, it needs to be corrected in time. [0003] Because the existing scraper machine is connected with the push cross head of the bracket through the pushing ear on the middle groove, therefore, in the process of pushing the bracket,...
