Wireless sight distance control system of small underground trackless carry-scraper

Abstract

The invention discloses a wireless sight distance control system of a small underground trackless carry-scraper. A sight distance remote receiver (2) is connected with an execution controller (4) through a CAN (Controller Area Network) bus (3); an electric control travelling pedal (6), an electric control steering handle (7), an electric control working handle (8), an electric control braking switch (9), an electric control accelerator switch (10), an electric control flameout button (11), a change-over switch (17), an electric control multiway valve group (12), an electromagnetic directional valve (13), an accelerator executor (14), a flameout electromagnetic valve (15), an electric control variable pump (16), a horn assembly (24), a starting motor (25) and the like are connected with the execution controller (4); and a slight distance remote transmitter (1) is provided with a travelling handle (1-1), a steering rocker (1-2), a working handle (1-3), a power switch (1-4), a power indicator (1-5), a horn button (1-6), an emergency braking button (1-7), an accelerator switch (1-8), a flameout button (1-9) and a starting button (1-10). The wireless sight distance control system is time-saving and labor-saving to operate, high in precision, small in occupied area, low in mechanical failure rate, capable of relieving the working intensity, safe and reliable.

Description

Technical field: [0001] The invention relates to a control system, in particular to a wireless line-of-sight control system for a small underground trackless scraper. Background technique: [0002] At present, in the existing wireless line-of-sight control system for small underground trackless scrapers, the variable pump is a mechanically controlled variable pump. Due to the existence of mechanical manufacturing errors in this structure, especially after the structure is worn out, the operation accuracy is poor and the action is not in place. In addition, due to frequent operations, failures such as pin shaft breakage often occur. The hydraulic steering gear is used to control the action of the steering cylinder, because it is not electronically controlled, and the remote control steering function cannot be realized. The manual multi-way valve is used to control the hydraulic circuit of the system through a mechanical working mechanism. Not only is the manufacturing proces...

AI Technical Summary

Problems solved by technology

The manual multi-way valve is used to control the hydraulic circuit of the system through the mechanical working mechanism. Not only is the manufacturing process complicated, it takes up a lot of space, but it also has the disadvantages of laborious operation, easy wear and poor precision.

The manual reversing valve is used to control the braking action, the failure rate is high, and remote control cannot be realized

The throttle cable is used to manually control the throttle of the diesel engine, and the flameout cable is used to manually control the diesel engine to shut down. After the cable is deformed, the operation accuracy is poor and the action is not in place.

Since the remote control cannot be realized, the driver can only carry out shoveling, loading and transporting operations in the scraper. In this way, when operating underground, when the roof of the underground working face collapses and the rocks slip, etc., it will bring danger to the driver and cause great harm. reduces the safety factor of downhole operations
