Embodiment Construction

[0011] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0012] Such as figure 1 As shown, the pneumatic brake control system of the rake bucket rock loader of the present invention includes a brake valve 1 and an actuator. The actuator includes a pneumatic component 2 and a lever mechanism 3. The pneumatic component 2 is hingedly installed on the bucket On the rock machine, one end of the lever mechanism 3 is hinged to the pneumatic element 2, and the other end of the lever mechanism 3 is hinged to the brake valve 1. The lever mechanism 3 includes a plurality of connecting rods. One of the connecting rods is a spring rod 5, and the spring rod 5 includes a cylinder, a polished rod that is sleeved in the cylinder an...

Abstract

The invention relates to a pneumatic braking control system of a scraper loader. The pneumatic braking control system comprises a brake valve and an executing mechanism, wherein the executing mechanism comprises a pneumatic element and a lever mechanism; the pneumatic element is arranged on the scraper loader in an articulated manner; the pneumatic element is articulated at one end of the lever mechanism; the brake valve is articulated at the other end of the lever mechanism; the lever mechanism comprises multiple connecting rods which are sequentially articulated end to end; one of the multiple connecting rods of the lever mechanism is a spring rod; and the spring rod comprises a cylinder sleeve, an optical rod sleeved in the cylinder sleeve and a spiral spring sleeved outside the cylinder sleeve and respectively connected to the cylinder sleeve and the end part of the optical rod. As a spring type buffering element is additionally arranged to slow down the functional force of the pneumatic element, the pneumatic braking control system of the scraper loader improves operability and satisfies demands of the practical conditions.

Description

technical field [0001] The invention relates to the technical field of mine mining equipment, in particular to a pneumatic brake control system of a rake bucket rock loader. Background technique [0002] The planetary drive rake bucket rock loader is the most common loading machine used for underground coal mine excavation in my country. The operating system of the existing planetary drive rake bucket rock loader controls the brake handle of the winch, and the work and air of the winch are controlled by the linkage mechanism. The process of braking the stroke roller, the power source of the control system is manpower, especially the large-section and large-scale rake bucket rock loader required in the large-section advancement and rapid construction of mine roadways, due to the operator's effort during the operation The labor intensity is greatly increased, and the flexibility and accuracy of the device are greatly reduced. The operating force provided by the operator brakes ...
