[0004] Further, the support frame is an X-shaped support frame.

[0005] Further, the hoisting device is an electric hoist.

[0006] The utility model has the advantages compared with the prior art: the utility model adds a belt roller support device at the tail of the shield machine, which can support the belt by arranging fixed rollers and movable rollers, optimize the support structure of the belt, reduce the leakage of slag, reduce the maintenance requirements, and thus improve the tunneling efficiency and operation continuity of the shield machine.

[0009] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0010] In the description of the embodiments of the present application, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present application is usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0011] In addition, if the terms "horizontal", "vertical", "overhanging" and the like do not mean that the component must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0012] In the description of the embodiments of the present application, "a plurality of" represents at least 2.

[0013] In the description of the embodiments of the present application, it should also be noted that unless otherwise explicitly specified and limited, if the terms "providing", "installing", "connecting", "connecting" appear, they should be understood in a broad sense, for example, they can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the communication between the two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0014] Embodiment:

[0015] In conjunction with the drawings Figure 1 , 2The embodiment discloses a belt roller supporting device for a tail part of a shield machine, which is arranged on a steel frame 1 of the tail part of the shield machine and comprises a horizontal shield tail fixing support 2, a plurality of roller support I 3 arranged on the bottom of the shield tail fixing support 2 downwards, the roller support I 3 being located on both sides of a belt 4 of the tail part of the shield machine, a fixed roller 5 arranged on the roller support I 3 and supporting the belt 4 of the tail part of the shield machine downwards, a support frame 6 arranged on the top of the shield tail fixing support 2 and connected with the steel frame 1 of the tail part of the shield machine, a movable roller support 7 arranged on the bottom of the support frame 6 and hinged away from the steel frame 1 of the tail part of the shield machine, the movable roller support 7 being connected with the top of the support frame 6 through a hoisting device 8, a roller support II 9 arranged on the bottom of the movable roller support 7 and located on both sides of the belt 4 of the tail part of the shield machine, and a movable roller 10 arranged on the bottom of the roller support II 9 and supporting the belt 4 of the tail part of the shield machine downwards, wherein the support frame 6 is an X-shaped support frame 6, and the hoisting device 8 is an electric hoist.

[0016] In the specific implementation, first, the support frame support and the shield tail fixed roller support are welded on the steel frame of the tail part of the shield machine, the movable roller support is hinged with the support frame support and pulled by the electric hoist; after the modification is completed, when the shield machine is excavated forward, the rollers located at the shield tail fixed roller support gradually move away from the fixed support of the segment, causing the belt to gradually sag; once it is detected that there is a risk of overflow of the muck, the movable roller support is lowered to support the sagging belt; with the continuous excavation of the shield machine, the electric hoist can be adjusted to ensure that the belt maintains appropriate tension and avoids sagging; after the shield machine excavates three to four segments, the rear segment fixed support is installed, and the movable roller support is lifted by the electric hoist, and a cycle is completed; the rear shield machine continues to advance, and the next cycle is started.

[0017] The above describes the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
