DETAILED DESCRIPTION

[0021] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0022] See also Figures 1 to 3 The embodiment of the utility model discloses a shield machine trolley track support device 10, including an arc-shaped bottom plate 101, a supporting structure, a first slot component and a second slot component. The top surface of one end of the arc-shaped bottom plate 101 is fixedly provided with a first slot component, and the first slot component is used to be fixed to the outside of the battery car track sleeper 20. The top surface of the other end of the arc-shaped bottom plate 101 is fixedly provided with a supporting structure, and the top surface of the supporting structure is fixedly provided with a second slot component, and the second slot component is used to fix the shield machine trolley track 40.

[0023] like Figure 3 As shown, in the shield machine trolley track support device of the utility model, the curvature of the arc bottom plate 101 is adapted to the curvature of the pipe segment 50, and the arc bottom plate 101 is closely attached to the top surface of the pipe segment 50. With the help of the arc bottom plate 101, the load of the shield machine trolley can be evenly transferred to the pipe segment 50, thereby avoiding damage to the tunnel pipe segment 50 due to excessive concentration of the support load. The bottom of the shield machine trolley track 40 is inserted into the second slot member, so that the shield machine trolley track 40 can be limited in the left and right directions to prevent the shield machine trolley track 40 from moving left and right to a large extent. The first slot member is used to be clamped on the outside of the battery car track sleeper 20, and the shield machine trolley track support device 10 can be fixed as a whole, thereby effectively stabilizing the shield machine trolley track 40. The clamping and fixing method adopted by the shield machine trolley track support device has a relatively simple structure and is also convenient for disassembly and assembly.

[0024] like Figure 1 and Figure 2 As shown, the first slot component includes an end plate 131 and two side plates 132 fixed on one side of the end plate 131. The end plate 131 and the side plates 132 together construct a side-opening U-shaped structural member, which is fixed on the side clamping plate 30 of the battery vehicle sleeper 20.

The reinforcing rod 120 is preferably a threaded steel bar. On the one hand, the reinforcing rod 120 can provide horizontal force for the supporting structure and the first slot component to keep the device stable; on the other hand, a gap is left between the reinforcing rod 120 and the arc-shaped bottom plate 101, which is convenient for installation workers to carry and improves the safety of installation and use of the device.

[0027] like Figure 1 As shown, the support structure includes an intermediate support plate 111 and side support plates 112 fixedly arranged on both side walls of the intermediate support plate 111, the top ends of the side support plates 112 are fixedly connected to the horizontal top plate 141, the bottom ends of the side support plates 112 are fixedly connected to the arc-shaped bottom plate 101, and the intermediate support plate 111 is arranged along the length direction of the arc-shaped bottom plate 101. Preferably, two side support plates 112 are arranged at intervals on both sides of the intermediate support plate 111 along its length direction. The support structure composed of four side support plates 112 and one intermediate support plate 111 can transmit the force of the track to the arc-shaped bottom plate 101 more evenly.
