Description

Technical Field

[0001] The utility model relates to the technical field of isolation rings, in particular to an isolation ring for a shield machine cutter. Background Art

[0002] In the assembly of the shield machine cutter, it is usually connected with the help of bearings, and isolation rings are usually installed between the bearings to increase the service life, so as to further increase the speed of the bearing itself. It is usually made of steel and is divided into DT, DB, DF, etc.

[0003] The above-mentioned and existing related technologies often have the following defects: in the process of combining the isolation ring and the bearing, they are generally connected by simply shrinking the contact surfaces inward and outward. This method can only achieve a single fit and it is difficult to achieve a firm effect. Therefore, in the later operation of the hob, the isolation ring is prone to shaking due to the simple fit, thereby increasing the wear between the two and reducing the bearing accuracy.

[0004] Therefore, we propose a shield machine cutter isolation ring. Utility Model Content

[0007] The effect achieved by the above components is: achieving the effect of limiting the position between the inner bearing and the isolation ring of the shield machine cutter, thereby avoiding as much as possible that the isolation ring and the bearing are only fitted with a single inner and outer shrinkage surface. Therefore, during the operation of the cutter, the isolation ring is prone to shaking and causing the bearing to wear.

[0010] Preferably, an iron plate is fixedly connected to the inner wall of the isolation ring, a magnet is fixedly connected to the side of the limit plate close to the iron plate, and one side of the magnet is attracted to the iron plate.

[0011] The effect achieved by the above components is: the limit plate drives the magnet to attract the iron plate, and the magnet achieves the effect of temporarily fixing the limit plate to prevent it from bulging during the transportation of the isolation ring.

[0012] Preferably, a clamping rod is fixedly connected to the lower end of the screw rod, and the arc surface of the clamping rod is slidably connected to the inner wall of the circular hole.

[0013] The effect achieved by the above components is that the screw rod drives the clamp rod to insert into the inner wall of the circular hole, and the clamp rod plays a role in preventing the screw rod from directly contacting the circular hole and causing damage to the thread.

[0014] Preferably, a limiting rope is fixedly connected to the upper surface of the rotating plate, the other end of the limiting rope is fixedly connected to the fixing cover, and the limiting rope is an elastic rope.

[0016] Preferably, a buffer pad is fixedly connected to a side of the limiting plate away from the magnet, and one side of the buffer pad abuts against an inner wall of the fixed cover.

[0017] The effects achieved by the above components are: the limit plate drives the buffer pad to fit with the inner wall of the fixed cover, and the buffer pad plays a role in reducing the vibration intensity after the limit plate is fixed.

[0018] Compared with the prior art, the beneficial effects of the utility model are: it achieves the effect of limiting the bearing and the isolation ring inside the shield machine cutter, and after the two are connected and limited by the limiting plate, the stability of the isolation ring itself is further increased, and the wear of the isolation ring caused by looseness is minimized during the use of the cutter, thereby further improving the use strength of the bearing, and the limiting plate can also be retracted by the sliding rod to avoid damage caused by excessive protrusion during transportation.

Therefore, during the operation of the cutter, the isolation ring 2 is prone to shaking and causing the bearing 1 to wear.

[0027] The specific setting and function of the limiting structure 3 will be described in detail below.

[0028] like Figure 2-Figure 5As shown, the limiting structure 3 includes a fixed cover 301, the lower surface of the fixed cover 301 is fixedly connected to the bearing 1, the upper surface of the fixed cover 301 is threaded with a screw 302, the upper end of the screw 302 is fixedly connected to a rotating plate 303, the inner wall of the fixed cover 301 is slidably connected to a limiting plate 304, the upper surface of the limiting plate 304 is provided with a circular hole 305, the circular hole 305 is located below the screw 302, the upper surface of the limiting plate 304 is provided with a sliding hole 306, the inner wall of the sliding hole 306 is slidably connected to a sliding rod 307, the lower surface of the sliding rod 307 is fixedly connected to the inner wall of the isolation ring 2, and the upper surface of the sliding rod 307 is fixedly connected to There is a top plate 308, the lower surface of the top plate 308 is in contact with the limit plate 304, the sliding hole 306 of the limit plate 304 slides on the surface of the sliding rod 307 and fits with the top plate 308, the top plate 308 prevents the sliding rod 307 from detaching from the sliding hole 306, the inner wall of the isolation ring 2 is fixedly connected with an iron plate 309, the side of the limit plate 304 close to the iron plate 309 is fixedly connected with a magnet 310, one side of the magnet 310 is attracted to the iron plate 309, the limit plate 304 drives the magnet 310 to attract the iron plate 309, and the magnet 310 can achieve the effect of temporarily fixing the limit plate 304 to prevent bulging during the transportation of the isolation ring 2.

[0029] The lower end of the screw rod 302 is fixedly connected with a clamping rod 311, and the arc surface of the clamping rod 311 is slidably connected with the inner wall of the circular hole 305, and the screw rod 302 drives the clamping rod 311 to insert into the inner wall of the circular hole 305, and the clamping rod 311 plays a role in preventing the screw rod 302 from directly contacting the circular hole 305 and causing damage to the thread. The upper surface of the rotating plate 303 is fixedly connected with a limiting rope 312, and the other end of the limiting rope 312 is fixedly connected to the fixing cover 301. The limiting rope 312 is an elastic rope. The rotation of the rotating plate 303 drives the limiting rope 312 to move the rod, and the limiting rope 312 can achieve the effect of temporarily fixing the screw 302 to prevent loss. The side of the limiting plate 304 away from the magnet 310 is fixedly connected with a buffer pad 313, and one side of the buffer pad 313 abuts against the inner wall of the fixing cover 301.

[0030] Working principle: when it is necessary to connect the bearing 1 and the isolation ring 2, first fit the bearing 1 and the isolation ring 2, and then move the limit plate 304 to the side close to the fixed cover 301, and the sliding hole 306 on the upper surface of the limit plate 304 slides from the surface of the sliding rod 307. During the movement of the limit plate 304, it fits with the top plate 308, and the top plate 308 prevents the sliding rod 307 from separating from the sliding hole 306. The magnet 310 is separated from the iron plate 309 through the limit plate 304. The magnet 310 can temporarily fix the limit plate 304 to prevent it from bulging during the transportation of the isolation ring 2. Until the limit plate 304 drives the buffer pad 313 to fit with the inner wall of the fixed cover 301, the buffer pad 313 reduces the vibration intensity after the limit plate 304 is fixed, and the moving rotating plate 303 drives The screw rod 302 is inserted into the fixed cover 301. At this time, the limiting rope 312 limits the rotating plate 303 through the fixed cover 301. The limiting rope 312 can temporarily fix the screw rod 302 to prevent it from being lost. After the screw rod 302 drives the clamping rod 311 to be inserted into the fixed cover 301 through the rotating plate 303, the rotating plate 303 is rotated to the side close to the limiting plate 304. The screw rod 302 rotates and moves through the fixed cover 301, thereby driving the clamping rod 311 to insert into the inner wall of the circular hole 305 of the limiting plate 304. The clamping rod 311 prevents the screw rod 302 from directly contacting the circular hole 305 and causing damage to the thread, thereby limiting the limit plate 304 from moving, thereby limiting the position between the bearing 1 and the isolation ring 2. Finally, the shield machine drives the roller to work, and the bearing 1 drives the isolation ring 2 to rotate through the roller.
