Cab with short and long head and wide view for mining

Abstract

The invention relates to the field of mining equipment, in particular to a cab with a short and long head and wide view for mining. A left framework and a right framework are installed on the left and right sides of the anterior portions of supporting girders respectively, and the left framework and the right framework are connected to an anti-collision fixing frame through an anti-collision girder arranged on the anterior portion; cuspidal windows are installed between the two supporting girders, cavities are formed among the anti-collision girder, the right framework, the left framework and the cuspidal windows, and the right framework and the left framework are of steel-bar framework structures; the upper portions of the supporting girders are provided with top frames, and the middle portions of the supporting girders are connected with chair supports, and the chair supports and the lower portions of the supporting girders are connected to a right fixing frame and a left fixing frame respectively, the left fixing frame, the right fixing frame, the chair supports and the rear portions of the top frames are connected with each other through back supports; the right framework and the left framework are arranged from the cuspidal windows and tilt forwards, and eachcuspidal window comprises two parts including a left window and a right window. The cab with the short and long head and the wide view for mining has a light cab head and meets the design demand of lightweight vehicles.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a short and long head cab for mining with a wide field of vision. Background technique [0002] The cab of the mining vehicle is used as a protective device for the driving operator. In the field of mining trackless rubber-tyred vehicles, most of the cabs are limited by the appearance size and development cost of the vehicle: 1. Borrowing the stamped and welded structure cab of the road vehicle; 2. Adopting a simple tailor-welded structure cab. This structural cab has the following defects: 1. Poor strength (usually the thickness of the stamped steel plate is 0.5-0.8mm) is prone to scratching and deformation under complex working conditions in the underground roadway (many curves and small width), and at the same time, it is harmful to the driver. Security is bad. 2. The appearance is ugly (mainly for the cab with simple tailor-welded structure), does not conform to the principl...

Problems solved by technology

This structural cab has the following defects: 1. Poor strength (usually the thickness of the stamped steel plate is 0.5-0.8mm) is prone to scratching and deformation under complex working conditions in the underground roadway (many curves and small width), and at the same time, it is harmful to the driver. safety disadvantage

2. The appearance is ugly (mainly for the cab with simple tailor-welded structure), does not conform to the principle of fluid mechanics, the air resistance is large, and it is not energy-saving and environmentally friendly.

However, the device of this invention also has the disadvantages of complex structure, heavy vehicle, narrow field of vision and large production cost in small batches.
