In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may include, for example, a fixed connection, an integral connection, or a detachable connection; may be communication within two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art can understand the specific meaning of the above terms in the present invention in specific situations.

The utility model discloses a preferred embodiment is shown in fig. 1-3, and the pipeline crawler tire of easy dismouting includes tyre body 1, first latch segment 2 and second latch segment 3 at least, and tyre body 1 includes lateral surface 103 and medial surface 104, and the axle center that surrounds tyre body 1 on lateral surface 103 is equipped with first latch segment mounting groove 12, and the axle center that surrounds tyre body 1 on medial surface 104 is equipped with second latch segment mounting groove 13, first latch segment 2 is detachable to be located in the first latch segment mounting groove 12, the detachable location of second latch segment 3 in second latch segment mounting groove 13, one side that second latch segment 3 dorsad first latch segment 2 is equipped with the pivot slot 32 that is used for installing pivot 4. First latch segment 2 and second latch segment 3 press from both sides tight tyre carcass 1 from both sides, simultaneously according to the metal material of chooseing for the holistic focus of pipeline crawler tire of easy dismouting is close to the rotation axis as far as possible, makes the rotation of tyre carcass 1 more steady.

Above-mentioned design still includes following advantage, when dismantling tyre body 1, only need with the tyre body follow second latch segment 3 take off can, because tyre body 1 makes for non-metallic material, lead to connecting the problem of dismantling more difficult and not serious because of rustting between tyre body 1 and the second latch segment 3, even rust between second latch segment 3 and the pivot 4 and glue the jail, do not influence the dismantlement of tyre body 1 and first latch segment 2 yet, avoided in case rusty just being difficult to take off the problem of tyre body 1.

Preferably, be equipped with the spacing hole 14 that communicates the two between first latch segment mounting groove 12 and the second latch segment mounting groove 13, the diameter in spacing hole 14 is less than the diameter of first latch segment mounting groove 12 and the fast mounting groove 13 of second locking, second latch segment 3 is equipped with the spacing portion 330 with spacing hole 14 adaptation towards one side of first latch segment 2, spacing portion 330 inserts and sets up in spacing hole 14 to provide further spacing to second latch segment 3, prevent that second latch segment 3 from taking place the skew.

Further, as an optimal connection mode of the first locking block 2 and the second locking block 3, a first connection screw hole 22 is formed in the position of the rotation axis of the first locking block 2, a second connection screw hole 320 is formed in the position, corresponding to the first connection screw hole 22, of the second locking block 3, and the second connection screw hole 320 is communicated with the rotation shaft slot 321. According to the scheme, the first locking block 12 and the second locking block 13 can be fixed by one bolt, meanwhile, screw holes can be further formed in the rotating shaft 4, the first locking block 12, the second locking block 13 and the rotating shaft 4 can be fixedly connected by one bolt, and the use is very convenient.

In order to facilitate the transmission of torque by the rotating shaft 4, as shown in fig. 6, a driving pin 41 is generally disposed at the output end of the rotating shaft 4 for driving, and as a preferred embodiment, a pin slot 321 adapted to the driving pin 41 is further disposed at a position close to the slot inside the rotating shaft slot 32, so that the rotating shaft 4 drives the pipeline crawler tire to rotate.

In order to better adapt to the shape of the duct, the outer edge of the carcass is provided with an arc-shaped tread 102, the arc-shaped tread 102 having, in a radial section of the carcass 1, a circular arc shape. The arc-shaped tread 102 is matched with the wall surface of the pipeline, so that the tyre body 1 can roll on the wall surface of the pipeline in a sticking mode, and the stability of the tyre body 1 in the rolling process is improved. Furthermore, in order to prevent sundries in the pipeline from blocking the tyre body 1, a plurality of mud discharge grooves 101 are formed in the outer edge of the tyre body 1, the mud discharge grooves 101 can increase friction between the tyre body 1 and the pipeline, and meanwhile, the effect of discharging the sundries can be achieved, so that the rolling of the tyre body 1 is more stable.

As a second embodiment of the present invention, a plurality of first locking block fixing screw holes 21 extending axially along the tire body 1 are further provided on the first locking block 2, and a tire body fixing hole 11 having the same diameter as the first locking block fixing screw hole 21 is provided in the first locking block mounting groove 12 corresponding to the first locking block fixing screw hole 21, and the tire body fixing screw hole 11 communicates with the second locking block mounting groove 13. The second locking block 3 is also provided with a second locking block fixing screw hole 31 at a position corresponding to the tire body fixing screw hole 11, and the second locking block fixing screw hole 31 is a through hole. In the design, when the first locking block 2, the second locking block 3 and the tyre body 1 are fixed, the first locking block 2, the second locking block 3 and the tyre body 1 can be fixed only by sequentially installing the first locking block fixing screw hole 21, the tyre body fixing screw hole 11 and the second locking block fixing screw hole 31 by using bolts, and the first locking block 2 and the second locking block 3 compress the tyre body 1 from two sides respectively.

Further, as shown in fig. 4 and 5, the design of the second embodiment can further simplify the step of replacing the tire casing 1. When the pipeline crawler tire of the easy dismouting of different wheel footpaths of design, the size of fixed first latch segment mounting groove 12 and second latch segment mounting groove 13 is unchangeable for pipeline crawler tire of the easy dismouting of different wheel footpaths can install the first latch segment 2 and the second latch segment 3 of equidimension. Meanwhile, a second locking block fixing screw hole 31 is formed in the second locking block 3, and extends to a position flush with the rotating shaft slot 32 in the length direction as shown in fig. 4. When changing less tyre body 1 for bigger tyre body 1, because first latch segment 2 and the 3 size unanimity of second latch segment of both installations, only need take out the bolt, then with the second latch segment 3 alignment of great tyre body 1 first latch segment 2 of less tyre body 1, then reuse the bolt installation advance the two internal fixation can, the trouble of having removed less tyre body 1 down has been removed, it is more convenient to make the part change, simultaneously because the length of the fixed screw hole 31 of second latch segment has been prolonged, make it can wrap up the bolt completely, can avoid the bolt to expose outside and rust.

In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
