Adjustable hinge-joint steering device for explosion-proof type crawler-type rock raking machine

Abstract

The invention discloses an adjustable hinge-joint steering device for an explosion-proof type crawler-type rock raking machine and belongs to the field of mining machinery. The adjustable hinge-joint steering device for the explosion-proof type crawler-type rock raking machine comprises a working mechanism (1), a machine frame (5), knuckle bearings (3) and hinge pins (2), wherein the knuckle bearings are arranged on a hinge-joint head of the machine frame, the hinge pins penetrates the knuckle bearings to connect the working mechanism with the machine frame, and the tail end of each hinge pin is provided with a locknut (4); and the hinge pins are fixed onto the working mechanism through bolts (7). The adjustable hinge-joint steering device for the explosion-proof type crawler-type rock raking machine has the advantages that when the adjustable hinge-joint steering device for the explosion-proof type crawler-type rock raking machine is utilized and when the hinge pins are in contact with the top surfaces of the knuckle bearings, the lifting or descending of the working mechanism can be achieved through the different locking degrees of the nuts at the tail ends of the hinge pins, the flexible adjustment of the gap between the working mechanism and the machine frame can be achieved, meanwhile the steering sensitivity of the working mechanism can be improved, the requirements of installation can be well met, and requirements on the steering of the working mechanism of the rock raking machine on a construction site can also be met.

Description

technical field [0001] The invention relates to a steering device, in particular to an adjustable articulated steering device for an explosion-proof crawler-type rock scraper, which belongs to the field of mining machinery and equipment. Background technique [0002] The rock scraper is a kind of mining machinery that integrates mechanical, hydraulic, and electrical technologies. Through the cooperation of various components, it can push and scoop rocks and scrape the rocks into its own scraper conveyor, and then unload the rocks into the car through the conveyor. , mining trucks or other reloading equipment; at the same time, the backhoe digging arm can also be used to pick up rocks in the distance, and the bucket can be used to clean the working face. During use, it was found that most of the existing explosion-proof crawler-type rock scrapers use a pin shaft with a length of 600mm to rigidly connect the working mechanism and the frame. This connection structure makes it i...

Problems solved by technology

During use, it was found that most of the existing explosion-proof crawler-type rock scrapers use a pin shaft with a length of 600mm to rigidly connect the working mechanism and the frame. This connection structure makes it impossible to flexibly adjust the gap between the working mechanism and the frame. , Sometimes there will be welding deformation that leads to the failure to connect; the working mechanism is not sensitive to steering, which is laborious and time-consuming, which affects the construction efficiency. This phenomenon is more obvious during the process of rock excavation;
