Embodiment Construction

[0050] The following examples are combined with the attached Figure 1-8 , the technical solutions of the present invention are further described in detail.

[0051] as attached Figure 1-3 As shown in the figure, the present embodiment provides an alternative trolley for the rear supporting wheels of the complete tunnel boring machine passing through the station. Wheel train frame 2 and 4 nylon wheels 1.

[0052] as attached Figure 4 As shown, the nylon wheel set 1 includes an axle 21, a bearing mounting frame 22, a steel sleeve 23, a grooved nylon wheel 24, an outer bearing cover 25, a rubber sealing ring 26, an inner bearing cylinder 27, a gasket 28, and a rolling bearing 29 and load-bearing cylinder 30.

[0053] The steel sleeve 23 in the nylon wheel set 1 is its bracket, one end of which is provided with a small oil injection hole, and the ring welding block in the middle acts as a reinforcing rib; near the two outer ends, a row of uniformly distributed circumferenti...

Abstract

The invention provides a replacement trolley of a rear matched wheel for station crossing of a whole tunnel boring machine. The replacement trolley comprises an upper supporting frame, a wheel train frame and a nylon wheel set. The wheel train frame comprises a frame, a middle combined frame and a rotating shaft, a nylon wheel set is arranged at the bottom of the frame, the frame is connected with the middle combined frame through the rotating shaft, and the frame and the middle combined frame can rotate around the rotating shaft by + / -8 degrees; the upper supporting frame is arranged on the top of the middle combined frame and provided with a rail used for bearing rear matched wheels. According to the invention, the special complete machine station-crossing replacement trolley is used for replacing steel wheels in the rear corollary equipment, directly rolls on the ground in the station and bears the rear corollary equipment to move forwards together with the main machine, so that compared with a station-crossing method in the prior art, the time is saved by 12-20 days, the whole construction period is effectively shortened, and a large amount of manpower and material resources can be saved.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to an alternative trolley for the rear supporting wheels of a tunnel roadheader when the whole machine passes through a station. Background technique [0002] Tunnel Boring Machine is a machine used for underground tunnel excavation. It is a complete set of excavation equipment that integrates excavation, support and slag removal. . The back supporting equipment of the roadheader is generally composed of about a dozen trailer cars with grooved steel wheels, which can be connected and disassembled. Two rows of steel rails are laid at the bottom of the tunnel. One side is dragged by the main machine and the supporting equipment rolls on the rails to carry out the assembly line operation. Usually, the height of the rails from the outer circular bottom surface of the main machine of the roadheader is about 1000-1400mm, that is, the rails and the bottom surface of the main machine e...
