Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction, and in particular to a device for transporting slag from a slope section of a tunnel. Background Art

[0002] With the rapid development of cities, ground traffic jams have become more frequent and serious. In order to ease the pressure on ground traffic, subways came into being. So far, subways have become the main traffic arteries of many cities, providing citizens with fast and convenient commuting services for work, school, business, and medical treatment.

[0003] When building a subway, most subway stations are generally located underground. In order to facilitate entry and exit of the subway station, escalators need to be built at the entrances and exits of the subway station.

[0004] During the construction of the escalator, it is necessary to excavate a tunnel. The tunnel is excavated at an inclined angle. The excavation slope angle is usually designed to be 30° to 45°, and the length of the slope section is 16 meters to 46 meters.

[0005] With the excavation of the tunnel, a large amount of slag is generally produced, and the slag is transported out of the tunnel by the staff. In the process of transporting the slag, the staff generally use a winch to lift it. The overall frequency of the winch lifting the slag is relatively low, which affects the overall efficiency of the slag transportation. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The present application embodiment discloses a device for transporting soil and slag from a tunnel slope section. Figure 1 , Figure 2 The tunnel slope section slag transport device includes a support leg 1 installed on the guide tunnel primary support frame 3 and a conveyor belt 2 fixedly connected to the support leg 1.

[0028] The pilot tunnel primary support frame 3 is a frame that supports the pilot tunnel during excavation to prevent the pilot tunnel from collapsing. The pilot tunnel primary support frame 3 includes an arch grid 31 and a primary support grid 32. The arch grid 31 is arranged at the top of the pilot tunnel, and the primary support grid 32 is arranged at the lower side of the pilot tunnel.

[0029] There are multiple groups of legs 1, and the legs 1 are connected to the primary support grid 32 located at the lower side of the pilot tunnel. Multiple groups of legs 1 are arranged along the excavation direction of the pilot tunnel. One end of the leg 1 is inserted into the invert concrete at the lower side of the pilot tunnel, and can be welded to the primary support grid 32 to increase the connection strength of the leg 1. As the excavation depth of the pilot tunnel increases, new legs 1 are arranged at intervals.

[0030] The conveyor belt 2 is fixedly connected to the legs 1, and the conveyor belt 2 is arranged at an angle as a whole. One end of the conveyor belt 2 is arranged in the guide tunnel, and the other end extends out of the guide tunnel. The bracket of the conveyor belt 2 is fixedly connected to multiple legs 1. When arranging the legs 1, legs 1 of different lengths can be selected. By changing the support height of the legs 1, the overall inclination angle of the conveyor belt 2 can be adjusted to facilitate transportation. The staff can shovel the slag onto the conveyor belt 2 in the guide tunnel. The conveyor belt 2 continues to run, and the slag can be continuously transported out, thereby improving the efficiency of slag transportation.

[0031] A fixed bracket is installed on the bracket of the conveyor belt 2, and the fixed bracket is fixedly connected with the bracket of the conveyor belt 2 by bolts, and a soil bucket 4 is installed on the fixed bracket, and the soil bucket 4 is in a V-shaped funnel shape as a whole, and the soil bucket 4 is installed on the side of the conveyor belt 2 located in the guide tunnel, and the soil bucket 4 is arranged on the upper side of the conveyor belt 2, and there is a gap between the lower side of the soil bucket 4 and the conveyor belt 2. The staff can pour the dregs into the soil bucket 4, and the dregs fall on the inclined conveyor belt 2 by the way of the soil bucket 4 leaking down.

[0032] A connecting bracket is installed on one end of the conveyor belt 2 located outside the guide tunnel. The connecting bracket is fixedly connected to the bracket of the conveyor belt 2 by bolts. A retaining plate 5 is fixedly connected to the connecting bracket. There is a gap between the retaining plate 5 and the conveyor belt 2, and the retaining plate 5 is used to block the debris flying from the conveyor belt 2 when the conveyor belt 2 transports the debris, so that the debris can fall into the receiving container on the outside.

[0033] A lifting ring 6 is fixedly connected to the arch grille 31. A plurality of lifting rings 6 are provided. The plurality of lifting rings 6 are arranged at intervals along the depth direction of the guide hole, and the lifting rings 6 can correspond to the upper and lower positions of the legs 1 arranged in the guide hole. By providing the lifting rings 6, the lifting rings 6 can lift and transport a new conveyor belt 2, providing installation, disassembly and maintenance conditions for the conveyor belt 2.

[0034] The implementation principle of a device for transporting slag from a slope section of a tunnel according to an embodiment of the present application is as follows: after the excavation of the guide tunnel is completed and the initial support frame 3 of the guide tunnel is arranged, the transport device is arranged in the guide tunnel, and then the staff shovels the slag into the earth bucket 4, and the slag falls from the earth bucket 4 onto the conveyor belt 2, and is transported to the outside of the guide tunnel. The conveyor belt 2 runs continuously, and the slag can be transported out of the guide tunnel in real time, thereby improving the efficiency of transporting slag.
