Problems solved by technology

Although the use of two-speed motors can solve the problem of two-wheel milling feed well, the price of two-speed motors is very high. Due to the lack of applications, there are few manufacturers, and it is not easy to repair after damage.
Another feeding method of the existing double-wheel milling machine is to use the ordinary reel oil cylinder to feed, the reel is connected to the oil cylinder through the pulley, the piston rod of the oil cylinder is hinged to the milling device, and the ordinary reel realizes the manual lifting of the milling device and lowering, the oil cylinder controls the feed speed and downforce of the milling device, but the oil cylinder invades the mud together with the milling device during work, which requires very high sealing, anti-corrosion, and impact resistance of the oil cylinder. Once the oil cylinder seeps, it will The entire hydraulic system will be damaged, and the length of the oil supply pipe of the oil cylinder can reach tens of meters or even hundreds of meters. The pressure loss is large, the power loss is large, and the construction cost is increased.

Abstract

The invention discloses a feeding device of a double-wheel slot milling machine and the double-wheel slot milling machine. The feeding device comprises an oil cylinder, wherein a cylinder barrel of the oil cylinder is hinged to a mast or a gooseneck boom of the double-wheel slot milling machine; a piston rod of the oil cylinder is connected with a milling device arranged below the oil cylinder; the oil cylinder can achieve differential motion together with a winding drum motor through a pulley device. According to the feeding device and the double-wheel slot milling machine, the oil cylinder does not need to be specially protected, the feeding speed and the feeding pressure of the milling device can be better controlled, the stroke replacement efficiency is improved, the structure is simple, the cost is lower, and the repair operation is convenient.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a feed device of a double-wheel slot milling machine and the double-wheel slot milling machine. Background technique [0002] As one of the most advanced equipment for underground diaphragm wall construction, the double-wheel slot milling machine has the advantages of high construction efficiency and good slot forming precision, especially when milling hard rock, its efficiency is more than three times that of other equipment. When milling hard rock, the footage of the double-wheel milling machine is only about half a meter per hour, which requires the double-wheel milling feed mechanism to achieve very slow feed, and the double-wheel milling in the process of working, for different For hard rock formations, the feed mechanism should always give different pulling forces to the milling device to prevent the milling device from milling off the slot. Most of the exist...
