Milling vibration punching type engineering slotting machine

Abstract

The invention relates to a milling, oscillating, smashing and smashing type engineering slotting machine, which includes hoisting equipment, a power system, a walking device and a monitoring device; a oscillating, smashing, and milling device is suspended on the traction end of the hoisting equipment; the oscillating, smashing, and milling device includes a longitudinal guide frame , rudder plate deviation correction device, milling shaft with milling cutter, and shock hammer; the axis of the milling shaft is located in the plane where the guide frame is located, and is arranged horizontally; the milling shaft is driven by a hydraulic motor; the milling shaft has an outer profile eccentric rotation In the rotating milling state, the hydraulic motor has a driving state of changing the rotating direction according to a preset cycle; the guide frame has a hydraulic oil pipeline communicated with the hydraulic motor. The present invention adopts the suspended frame to cancel the stroke drill rod, replaces the multi-drill bit structure with the milling shaft, and simultaneously cancels the reversing device or reduces the volume of the reversing device to reduce the volume of the slotting machine excavation device, so that it can be used in various rocks. Narrow and deep grooves are excavated in the soil layer, and the rudder plate deviation correction device is used to ensure the verticality of the groove.

Description

technical field [0001] The invention relates to a milling vibration punching type engineering slotting machine, which belongs to the technical field of slotting equipment. Background technique [0002] According to the knowledge of the inventor, in engineering fields such as water conservancy, transportation, and construction, it is necessary to build various underground continuous walls under different geological conditions. In the actual construction process, it is a very difficult and unresolved problem to open deep grooves on strata containing gravel, boulders, floating stones and relatively hard rock strata to build various underground continuous walls. The slotting machine developed by the inventor can be used to complete the slotting operation with high efficiency and low cost, and the effect is good. [0003] The Chinese invention patent (application number 201110273179.4, authorized announcement number CN102409972B) applied by the inventor on September 14, 2011 dis...

AI Technical Summary

Problems solved by technology

The inventor found in practical research that the stroke drill rods extending from the ground to the bottom of the groove in the above slotting machine are rigid double drill rods, which easily lead to uneven stress on the two rigid drill rods when excavating in uneven ground, and then breakage , buried drilling and other accidents, it is necessary to cancel the trip drill pipe to avoid this problem

At the same time, the above-mentioned slotting machine adopts a multi-drill structure, which not only requires multiple drills and corresponding sealing structures, but also needs a transfer case for driving multiple drills. At the same time, the frictional resistance of multiple drill seals also increases its power consumption.

[0004] In addition, among the related patents that the inventor has applied for before (such as the Chinese utility model patent of patent number CN99230153. Chinese invention patent with notification number CN101100865B) adopts a structure in which the reversing device is matched with the milling shaft, but the inventor found in subsequent practical applications that due to the large volume of the deceleration mechanism or the stroke drill rod, a large volume of The reversing device not only takes time and labor to connect and disassemble the stroke drill pipe, but also makes the whole slotting machine unable to dig narrow slots with small thickness, which limits the application range of the slotting machine
