Embodiment Construction

[0023] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0024] figure 1 A material handling device 91 for a tunnel boring machine according to the invention is shown. As shown in the figure, the hoisting device 91 includes a guide rail mechanism 31 for carrying and guiding transportation, which includes a guide rail 4 placed at the top of the tunnel. A first transmission member 3 is welded on the lower end surface of the guide rail 4 .

[0025] Such as figure 1 and 2 As shown, the hoisting device 91 also includes a power mechanism 32 that provides power along the direction of the guide rail 4 , which includes several power units 1 connected to the guide rail 4 . Inside the power unit 1, there is a second transmission member 104 that forms a stable transmission cooper...

Abstract

The invention relates to a material hoisting device for a tunnel boring machine. The material hoisting device for the tunnel boring machine comprises a guide rail mechanism, a power mechanism, a driven mechanism and a craning mechanism, wherein the guide rail mechanism comprises a guide rail and a first transmission part, the power mechanism comprises a power device and a connecting rod, the driven mechanism comprises a driven device and a driven machine frame, the craning mechanism comprises a balance frame, a hydraulic cylinder and a reverser. The reverser comprises a pulley wheel, a steel wire rope and a pulley wheel seat. Extension motion of the hydraulic cylinder is converted into lifting motion of the balance frame through the reversing of the steel wire rope and the pulley wheel, and accordingly material lifting is achieved. The power device and the first transmission part perform matched motion through the second transmission part to produce stable power, the stable power is acted on the driven mechanism through the connecting rod to enable the driven mechanism to drive the whole hoisting device to move together with the driven mechanism, and accordingly transportation of materials in the track direction is achieved. The material hoisting device for the tunnel boring machine has the advantages of being simple in structure, safe, reliable and high in efficiency, the problem that the materials and multiple tube pieces cannot be stably hoisted in a limited space at the same time is solved, and accordingly a construction schedule and the construction efficiency of the tunnel boring machine are guaranteed.

Description

technical field [0001] The invention relates to the field of tunnel construction machinery, in particular to a material hoisting device for a tunnel boring machine. Background technique [0002] In the field of tunnel construction machinery, tunnel boring machines have the advantages of low environmental impact, fast excavation speed, and small surface settlement during underground construction, so they are widely used in the construction of underground tunnels. [0003] At present, the tunnel boring machine is usually not equipped with a special material lifting device, but the material required for tunnel construction is transported to the front end of the tunnel boring machine trolley through the material transport vehicle, and then the segment (mainly Materials) are transported to the segment trolley, and other materials are unloaded with a cantilever crane at the corresponding position of the supporting trolley. However, since the material transport vehicle of the tunn...
