Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0024] see figure 1 , figure 2 , image 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , a tunnel excavation trolley, comprising a bottom trolley 1 and an upper trolley arranged on the bottom trolley 1; the upper trolley has at least one layer, and the upper trolley can travel longitudinally relative to the bottom trolley 1; And when the upper trolley has multiple layers, each layer of the upper trolley has independent walking power, and can walk longitudinally relative to the adjacent lower floor; the walking power is provided by the motor, and the driving and walking methods include wheels driven by pure electricity. The drive and travel methods of the type vehicles are the same, or the drive and travel methods of the rail vehicles are the same.

[0025] Among them, the bot...

Abstract

The invention discloses a tunnel excavating trolley. The tunnel excavating trolley comprises a bottom layer trolley body and an upper layer trolley body arranged on the bottom layer trolley body; oneor more layers are arranged on the upper layer trolley body, and the upper layer trolley body can longitudinally walk relative to the bottom layer trolley body; when the upper layer trolley body is provided with multiple layers, each layer of the upper layer trolley body has the independent walking power, and can longitudinally walk relative to the adjacent lower layer. Preferably, the bottom layer trolley body is loaded on a wheel type frame; the upper layer trolley body is composed of a middle layer trolley body and a top layer trolley body, and the middle layer trolley body can longitudinally walk relative to the bottom layer trolley body; the top layer trolley body can longitudinally walk relative to the middle layer trolley body; a trestle or a steel rail bridge or a hanging bridge isarranged at one end of the bottom layer trolley body and used for walking of the middle layer trolley body; a trestle or a steel rail bridge used for walking of the top layer trolley body is arrangedat one end of the middle layer trolley body. The tunnel excavating trolley has the advantages that multi-layer combination is realized, the trolley can adapt to full-section or double-step or three-step tunnel excavating through changes of a combination state, the application range is wide, repeated utilization can be realized, and the cost for tunnel excavating can be effectively lowered.

Description

technical field [0001] The invention relates to tunnel construction facilities, in particular to a tunnel excavation trolley. Background technique [0002] With the acceleration of domestic high-speed rail construction, the technology of high-speed rail tunnel construction facilities is also constantly improving. Tunnel excavation is a part of tunnel construction, and the excavation method needs to be designed according to the tunnel surrounding rock grade and other conditions. Existing tunnel excavation methods mainly include full-section excavation, two-step excavation, and three-step excavation. Existing excavation trolleys usually have a fixed structure and can only be adapted to one excavation method, which limits the scope of use of existing excavation trolleys, and cannot adapt to changes in excavation methods for structural changes, making it more difficult to repeat use. For this reason, it is necessary to further improve the existing trolley so as to adapt to va...
