Transmission system of hydraulic three-wheel slot milling machine

Abstract

The invention discloses a transmission system of a hydraulic three-wheel slot milling machine. The transmission system comprises a hydraulic motor set, a gearbox, shell rotation speed reducers and milling wheels; the gearbox comprises a box body, transmission gear sets and middle gear sets, wherein the transmission gear sets and the middle gear sets are installed inside the box body, the hydraulicmotor set is installed at the top of the box body of the gearbox, and output shafts of the hydraulic motor set are in meshed transmission with the transmission gear sets on first transmission shaftsin the gearbox through a plurality of sets of bevel gears; and three sets of shell rotation speed reducers are provided and are correspondingly arranged on the left, the middle and the right of the bottom of the box body, wherein an output gear is installed on the central shaft of each set of shell rotation speed reducers, the three sets of output gears are in meshed transmission connection with the transmission gear sets of the first transmission shafts through the three sets of middle gear sets respectively, two shell rotation reducers are provided in each set and are arranged front and back, and one milling wheel is installed on each shell rotation speed reducer. According to the technical scheme, the multiple stages of gears are reasonably used for transmission, the plurality of milling wheels are reasonably installed and arranged, so that the reliability and the efficiency of the hydraulic slot milling machine are improved, and the problem of milling wheels of an existing hydraulic double-wheel slot milling machine is solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic slot milling machines, in particular to a transmission system of a hydraulic three-wheel slot milling machine. Background technique [0002] The existing special equipment for underground diaphragm wall construction is mainly a hydraulic double-wheel milling machine imported from Germany and other countries. The standard milling depth is 44m, the maximum can reach 80m, and the milling width ranges from 650 to 1800mm. The horizontal length of the milling groove is 2800mm; according to the geological conditions, different types of milling cutter wheels can be replaced to meet the needs of continuous construction in various strata such as clay, silt, and rock formations. [0003] The transmission system of the milling machine and the steel cable under the mast suspend a steel milling tool holder with a hydraulic and electrical system that can be controlled by the main engine. Three hydraulic motors...

Problems solved by technology

[0004] The existing hydraulic double-wheel slot milling machine has the advantages of wide construction range, high efficiency, high precision, and low pollution. However, the one-time investment cost of the slot milling machine and supporting equipment is too expensive, and domestic maintenance capabilities are difficult to ensure the continuous operation of the slot milling machine. Need, the key is that the components are basically all dependent on
