Description

Technical Field

[0001] The utility model relates to the technical field of shield tail brushes, in particular to a shield tail brush for a separated shield machine. Background Art

[0002] The full name of the shield machine is a shield tunnel boring machine, which is a special engineering machinery used to dig tunnels. The main features of the shield machine include high automation, labor saving, fast construction, and no climate impact. It controls ground subsidence and reduces the impact on ground buildings by building a tunnel lining (i.e., a "shield") while excavating. The components of the shield machine include the shield head, cutter arm, cutter head, guide system, excavation system, support system, etc., which can perform precise excavation and support underground to form tunnels of various shapes and sizes. In order to seal the gap between the shield tail and the tunnel segment and prevent mud, groundwater, wall grouting materials, etc. from entering the tunnel from the shield tail, a shield tail brush will be added to the shield machine for blocking.

[0003] A shield tail brush for a shield machine is disclosed in the Chinese utility model patent with the announcement number CN218542253U. The device uses a shield tail brush, a metal frame, a threaded rod, a hexagonal nut 1 and a threaded bolt to thread the bristles and the metal connection frame, thereby preventing the bristles from loosening and falling, reducing the time for replacing the bristles, and by setting a limiting metal plate, a hexagonal nut 2 and a hexagonal nut 3, the metal connection frame can be fixed for a second time to prevent the metal connection frame from loosening, thereby increasing the service life of the metal connection frame and increasing the service life of the device. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, the hexagonal nut one, the hexagonal nut two and the hexagonal nut three need to be loosened in sequence before the shield tail brush can be disassembled and assembled. This is not only troublesome, but also increases the time spent on disassembly and assembly of the shield tail brush, thereby reducing the replacement efficiency of the shield tail brush. For this reason, we provide a split shield tail brush for a shield machine. Utility Model Content

[0005] In order to solve the problem in the above background technology that the disassembly and assembly process of the shield tail brush is relatively troublesome, which prolongs the time spent on replacing the shield tail brush, the utility model provides a separate shield tail brush for a shield machine.

[0008] A quick-loading and disassembly component includes a screw rod rotatably connected to a connecting plate, the external thread of the screw rod is connected to a threaded sleeve, the top of the cross plate is symmetrically fixedly connected to a hollow tube and the hollow tube is connected to a T-shaped slide groove, the inside of the hollow tube is slidably connected to an insertion rod, and a connecting rod is hinged between the top of the insertion rod and the threaded sleeve through a hinge.

[0009] As a further improvement of the above solution, the interior of the T-shaped slide groove is also movably connected to a limit plate, one side of the limit plate is rotatably connected to a second screw rod and the second screw rod is threadedly connected to the cross plate.

[0010] As a further improvement of the above solution, the top of the T-shaped slider is symmetrically provided with insertion holes, and the diameter of the insertion holes is matched with the diameter of the insertion rod.

[0011] As a further improvement of the above solution, guide rods are provided on both sides of the screw rod 1, and the guide rods are fixedly connected to the connecting plate, and the guide rods are slidably connected to the threaded sleeve.

[0012] As a further improvement of the above solution, the opening area of ​​the T-shaped slide groove is larger than the area of ​​the top of the T-shaped slide block.

[0013] As a further improvement of the above solution, when the T-shaped slider slides to the end, the insertion hole and the insertion rod are located on the same center line.

[0014] As a further improvement of the above solution, guide blocks are fixedly connected to both sides of the limit plate, and guide grooves are symmetrically opened inside the T-shaped slide groove and are slidably connected to the guide blocks.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model places a T-shaped slider into the T-shaped slide groove and slides it.
