An adjustable articulated steering device for explosion-proof crawler rock scraper

Abstract

The invention discloses an adjustable articulated steering device for an explosion-proof crawler-type rock scraper, which belongs to the field of mining machinery and equipment, and includes a working mechanism (1), a frame (5), and a joint bearing (3), a pin shaft (2), the joint bearing is arranged on the hinge joint of the frame, the pin shaft passes through the joint bearing to connect the working mechanism and the frame together, and a lock nut (4) is installed at the end of the pin shaft; Pin shaft is fixed on the working mechanism by bolt (7). The beneficial effect is: using the adjustable articulated steering device, when the pin shaft is in contact with the top surface of the joint bearing, depending on the different locking degrees of the nuts at the end of the pin shaft, the working mechanism can be raised or lowered, and the working mechanism and the machine can be realized. The flexible adjustment of the frame clearance can also improve the steering sensitivity of the working mechanism, which satisfies the assembly requirements and also meets the requirements for the steering of the working mechanism of the rock scraper on the construction site.

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;
