Series of coal mine backhoe loaders
Product Overview
. Mining crawler backhoe loaders (commonly known as slag scrapers) are high-efficiency motorized mining equipment for continuous production. They mainly realize Excavation, rock loading and conveying work.
Scope of product application
This machine is suitable for coal mines, non-coal mines, water conservancy, railways, highways, natural gas transmission, national defense and other engineering fields. It is mainly suitable for tunnel excavation working sections
Material collection, transportation and loading construction of tunnels with a meter and above.
Working Principle
The backhoe loader for coal mines is mainly composed of chassis system, excavation system, conveying system, hydraulic system, and electrical control system. It mainly implements walking, digging, collecting, conveying, loading, and site cleaning. and six other functions.
The backhoe loader for coal mines rationally combines the manipulator and the conveyor, and combines the collection and conveying functions into one. The entire equipment adopts an electro-hydraulic control system, and all movements are controlled by a pilot handle. The operation is easy and simple, and the work is smooth and impact-free. It has the characteristics of safety and environmental protection, low energy consumption, high efficiency, simple and compact structure, and easy maintenance. Among them, the principle of using electro-hydraulic as the power source has revolutionized the technical status quo of traditional models using diesel as the power source, solved the safety accidents caused by diesel exhaust emissions not meeting the standards, and effectively changed the on-site working environment.
The hydraulic system is mainly composed of hydraulic components such as variable hydraulic piston pumps, pilot pumps, multi-way valves, hydraulic cylinders, traveling motors, manual pilot valves, steel ball motors, etc. The whole machine is realized through division of labor and cooperation. various functions. (Add left and right pilot handles and single-chip handles)
The electrical control system mainly consists of mine explosion-proof electromagnetic starters, explosion-proof motors, mine explosion-proof locomotive lights, mining explosion-proof acoustic and photoelectric bells, mine explosion-proof It is composed of flameproof emergency stop button, etc., and the voltage level is selected according to the user. The above electrical devices all comply with the certification of the National Mining Product Safety Marking Center and have obtained coal safety certificates and explosion-proof certificates (
). (Adding
motorcycle lights and explosion-proof acoustic and optical bells)
Innovation in product application
The chassis of this product innovatively adopts a
segmented structure. On the premise of ensuring the function of the equipment, the chassis part of the equipment is disassembled into parts and a quick disassembly and installation method (invention patent) is applied, which reduces the transportation and assembly costs of the equipment. It solves the problem that when transporting over long distances in tunnels or mines, the chassis is often too large and heavy to transport or assemble (utility model patent).
Without changing the equipment's working capacity and safety factors, this product has made technological innovations in the chassis mechanism, equipment coverings, cab and other parts. Compared with domestic products of the same type, this product has The total height has been reduced by 3
, and the total height is
(the height of domestic products of the same type is
). This innovative part greatly improves the pass rate, reduces the turning radius of the product, reduces the potential safety hazards caused by the equipment blocking the tunnel, and is more in line with actual working conditions (appearance patent).
In order to meet various complex working conditions, the traveling mechanism of this product has changed the diameter of the guide wheel through a series of innovations, increasing the climbing angle between the crawler track and the ground plane in the traveling mechanism ()
and increasing the equipment's throughput. The ability to overcome obstacles greatly improves the passing rate of equipment after encountering obstacles. This method is the first of its kind in China (utility model patent).
The cab adopts an open design, with a simple and solid structure and a wide field of view. The cab is the first to use a real-time pressure monitoring device in the cab. The pressure values of the main pump and return oil line can be read in real time through the pressure gauge, which can effectively monitor the working conditions of the main pump and main circuit and reduce the equipment oil line failure rate.
