The underground continuous wall has the characteristics of large wall rigidity, good integrity, high seepage-proofing performance, short construction period, reliable quality, wide applicable foundation range and the like due to integral casting of the wall, and is more and more widely applied to the aspects of urban rail transit, water conservancy reservoirs, port construction, high-rise buildings and the like. The double-wheel slot milling machine is special equipment for processing the underground continuous wall.
In the construction process of the double-wheel slot milling machine, different types of milling wheels can be selected for use aiming at complicated and changeable stratum construction. When the standard gear milling wheel is constructed in a hard stratum, the milling teeth are seriously abraded, the consumption is large, the phenomena of tooth breakage and serious tooth plate abrasion easily occur, and the construction efficiency is extremely low; when the conical tooth milling wheel is constructed in a softer stratum, because the conical tooth alloy head is smaller, the conical tooth milling wheel is very easy to cut into the stratum, the conical tooth tip is not easy to scrape the stratum, the construction efficiency is low, and when the conical tooth milling wheel is constructed in a viscous stratum, because the teeth of the conical tooth milling wheel are densely arranged, the wheel is easily stuck. For the milling wheel with only a single type of milling wheel teeth, if the milling wheels with different types are selected according to strata with different properties, the milling wheels need to be frequently replaced, so that a large amount of time is wasted, the labor intensity is increased, and the construction efficiency is seriously reduced.

Taper teeth and standard teeth are arranged according to the following ratio of 1: the number ratios of 1 are distributed on the wheel hub alternately, and the running tracks of the conical teeth and the standard teeth are overlapped. The toothed plate is provided with a U-shaped groove, and the conical teeth and the standard teeth are fixed in the U-shaped groove through nylon pins. The hub is rotationally arranged on the milling wheel frame, and the milling wheel frame comprises a mud scraping plate. The mud scraping plate is arranged between two adjacent milling wheel assemblies, the detachable milling wheel assemblies are detachably mounted on the milling wheel frames, and the side wall of the mud scraping plate is close to the side wall of the toothed plate.
The running tracks of the conical teeth and the standard teeth are overlapped, the tooth tip height of the standard teeth is higher than that of the conical teeth, and the range of height difference is 10-20 mm.
The cutting angle range of the conical tooth is 50-60 degrees, and the middle value is 55 degrees in a normal state; the cutting angle of the gauge tooth ranges from 80 to 90 °, taking a median value of 85 ° in the normal state.
The toothed plate is provided with a U-shaped groove, and the conical teeth and the standard teeth are detachably fixed in the U-shaped groove through nylon pins. According to different conditions of the stratum, different sequences of the conical teeth and the standard teeth are adjusted, and the conical teeth and the standard teeth can also be installed on the same toothed plate.
The lateral wall of pinion rack is equipped with the mud scraper, and when milling wheel subassembly milled the work, the mud scraper cleared up the earth of adhesion on the board tooth lateral wall simultaneously.

fig. 2 is a schematic structural diagram of a milling wheel assembly of a multi-toothed plate and a double-wheel slot milling machine according to the present invention.
Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
As shown in fig. 1 and 2, the multi-toothed plate milling wheel assembly and the double-wheel slot milling machine of the present invention comprise a hub 1, an end cover 2, a toothed plate 3, a tapered tooth 4, a standard tooth 5, a U-shaped groove 6, a nylon pin 7, a mud scraper 8 and a milling wheel frame 9.
As shown in fig. 1 and 2, an end cover 2 is arranged on one side of a hub 1, the end cover 2 is connected with the hub 1 through bolts, and then the end cover 2 is fixed on one side of the hub 1 to prevent the side surface of the hub 1 from entering large milling rock debris. 1 surface of wheel hub is equipped with a plurality of pinion racks 3, is equipped with three continuous milling teeth on every pinion rack 3, including conical tooth 4 and standard tooth 5, conical tooth 4 and standard tooth 5 press 1: 1, along the direction of rotation of hub 1, the conical teeth 4 on the same toothed plate 3 are located in front of the standard teeth 5. When a softer stratum is milled, the stronger scraping capability of the standard teeth 5 is mainly utilized, and the milling efficiency is high; when milling hard stratum, the conical alloy head at the end part of the conical tooth 4 has good rock breaking capacity, the conical plate tooth 4 can generate pre-breaking to the stratum after milling, a large number of cracks are generated, the standard tooth 5 is milled after the conical plate tooth 4 is milled, milling resistance is reduced, meanwhile, the hard alloy head at the end part of the standard tooth 5 is wider, the stratum can be scraped better, and milling efficiency is improved. The conical teeth 4 on the toothed plate 3 are located in front of the standard teeth 5, which is a preferable scheme, but not limited to this, and the two types of milling teeth can be installed in no sequence, i.e. front and back, for different types of strata. The running tracks of the conical tooth 4 and the standard tooth 5 are overlapped, the tooth tip height of the standard tooth 5 is higher than that of the conical tooth 4, the height difference delta h ranges from 10 mm to 20mm, and the standard tooth 5 can better utilize a crack generated after the conical tooth 4 is milled during milling. The height difference delta h is too small, so that the conical teeth 4 cannot be fully utilized to pre-crush cracks generated by rocks; the height difference delta h is too large, the milling depth of the standard teeth 5 is larger, when the pre-crushed rock is milled, the lower complete and hard rock is milled, the resistance is larger, the milling efficiency is low, and the standard teeth 5 are seriously abraded; the specific height difference is selected according to actual working conditions and stratum types. Be provided with U type groove 6 on pinion rack 3, conical tooth 4 and standard tooth 5 are fixed in U type groove 6 in through nylon round pin 7, prevent to mill the tooth and drop.
