Description

Technical Field

[0001] This utility model relates to the field of sprocket technology, and in particular to the track track track roller structure for preventing chain slippage. Background Technology

[0002] Track carrier rollers (also known as track rollers) are the core components of the tracked vehicle's running system and one of the key components of the "four wheels and one track" system. They mainly support the upper track, limit the vertical vibration of the track, and maintain the track tension.

[0003] Existing track drag wheels are typically installed above the track during use, supporting the track's return section (non-grounded part) through rolling contact. This prevents the track from sagging excessively due to its own weight, reducing bouncing and lateral deviation during movement. However, because the track may experience lateral displacement during operation, the track may accidentally detach from the drag wheel, causing changes in the track's running track and abnormal friction with other components, affecting the normal operation of the equipment and the service life of the track. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the track may undergo lateral displacement during operation, causing it to accidentally detach from the track roller, resulting in a change in the track's running track and abnormal friction with other components, thus affecting the normal operation of the equipment and the service life of the track.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a track track roller structure for preventing track slippage, including: a track roller body, wherein two anti-detachment devices are symmetrically arranged on the surface of the track roller body, wherein the two anti-detachment devices limit the two sides of the track to prevent the track from falling off the track roller body when it moves left or right.

[0006] Preferably, the anti-detachment device includes: a plurality of threaded grooves, the plurality of threaded grooves being evenly opened on one side of the track roller body, wherein the inner wall of the threaded grooves is threaded with bolts; and an intercepting ring, the intercepting ring being sleeved on the track roller body, wherein the intercepting ring is sleeved on the track roller body and fixed by bolts.

[0007] The effect achieved by the above components is as follows: By setting up an anti-detachment device, the blocking ring is first manually moved to a position where it fits onto the surface of the track roller body. Simultaneously, the blocking ring continues to move left and right along the track roller body surface. When the blocking ring moves to a position that is close to or in contact with the edge of the track, the inner wall of the hole on the blocking ring coincides with the inner wall of any threaded groove. At this point, a bolt is screwed into the blocking ring and the threaded groove to fix the blocking ring in position. This fixes the blocking ring's position and places it at the edge of the track to intercept and limit it, thereby achieving anti-track skipping treatment. This reduces lateral displacement of the track during operation, preventing the track from accidentally detaching from the track roller, causing changes in the track's running track and abnormal friction with other components, affecting the normal operation of the equipment and the service life of the track. It also improves the support efficiency and stability of the track roller body for the track.

[0008] Preferably, a limiting groove is formed on one side of the chain roller body, and a limiting block is fixed to the inner wall of the blocking ring, wherein the limiting block is placed inside the limiting groove to assist in limiting and calibrating the position of the blocking ring.

[0009] The effects achieved by the above components are as follows: by setting the limiting block and the limiting groove, the limiting block can be placed inside the limiting groove to assist in limiting the blocking ring. At the same time, the limiting block can be inserted into the limiting groove to quickly position the blocking ring, so that the inner wall of the hole on the blocking ring can quickly correspond to the inner wall of the threaded groove, thereby improving the convenience and efficiency of personnel in installing and adjusting the blocking ring.

[0010] Preferably, a circular plate is fixed to one side of the blocking ring, wherein the side of the circular plate closest to the blocking ring is provided with multiple anti-slip protrusions.

[0011] The effect achieved by the above-mentioned components is that by setting up a circular plate, a point of leverage can be provided for personnel to manually move the blocking ring, so that personnel can manually pull the circular plate to move the blocking ring, thereby improving the convenience and stability of manually pulling the blocking ring.

[0012] Preferably, a plurality of support blocks are fixed to the inner side of the blocking ring, wherein the surface of the support blocks is trapezoidal.

[0013] The effect achieved by the above components is that the blocking ring can be supported and reinforced by the support block, reducing the possibility of tilting or deformation of the blocking ring when it is squeezed by the track.

[0014] Preferably, an auxiliary ring is fixed to the surface of the blocking ring, wherein the surface of the auxiliary ring is higher than that of the blocking ring.

[0015] The effect achieved by the above components is as follows: by setting an auxiliary ring, when the track accidentally flips over the surface of the blocking ring during the left and right displacement, the auxiliary ring can intercept the flipped track a second time, further improving the interception effect on the track.

[0016] Preferably, the blocking ring has multiple reinforcing ribs inside, wherein the reinforcing ribs are made of nickel alloy.

[0017] The effect achieved by the above components is that by setting reinforcing ribs, the strength of the blocking ring itself can be increased, reducing the possibility of the blocking ring breaking under stress.

[0018] Preferably, a wear-resistant plate is fixed to the side of the blocking ring near the main body of the chain wheel, wherein the wear-resistant plate is made of high manganese steel.

[0019] The effect achieved by the above components is that by setting wear-resistant plates, the wear-resistant plates can replace the blocking rings in contact with the edge of the track, reducing the wear caused by the track to the blocking rings during operation, and further improving the wear resistance and service life of the blocking rings.

[0020] The beneficial effects of this utility model are:

[0021] By setting up an anti-detachment device, the track supported by the track roller can be blocked in both directions. At the same time, it can be adapted to track of various sizes for limiting, reducing the lateral displacement of the track during operation, which could cause the track to accidentally detach from the track roller, resulting in changes to the track's running track and abnormal friction with other components, affecting the normal operation of the equipment and the service life of the track. This improves the support efficiency and stability of the track by the track roller. Attached Figure Description

[0030] Figure 1-4 The track carrier roller structure of the anti-jump chain shown includes: a carrier roller body 1, and two anti-detachment devices 2 symmetrically arranged on the surface of the carrier roller body 1. The two anti-detachment devices 2 limit the two sides of the track to prevent the track from falling off the carrier roller body 1 when it moves left or right.

[0031] Figure 2 , Figure 3 and Figure 4 The anti-detachment device 2 shown includes: multiple threaded grooves 21, which are evenly distributed on one side of the track roller body 1, wherein bolts 22 are threadedly connected to the inner wall of the threaded grooves 21; and a blocking ring 24, which is sleeved on the track roller body 1 and fixed by bolts 22. By setting the anti-detachment device 2, the blocking ring 24 is first manually moved to a position where it is sleeved on the surface of the track roller body 1, and the blocking ring 24 is moved left and right along the surface of the track roller body 1. When the blocking ring 24 moves to a position that is in contact with or close to the edge of the track, the anti-detachment device is activated. When the inner wall of the hole on the blocking ring 24 coincides with the inner wall of any threaded groove 21, the bolt 22 is screwed into the blocking ring 24 and the threaded groove 21 to fix the position of the blocking ring 24. This fixes the position of the blocking ring 24 and places it at the edge of the track to intercept and limit it, thereby achieving the anti-track skipping treatment. This reduces the lateral displacement of the track during operation, which could cause the track to accidentally detach from the track roller, resulting in changes in the track's running track and abnormal friction with other components, affecting the normal operation of the equipment and the service life of the track. This improves the support efficiency and stability of the track roller body 1 for the track.

[0032] Figure 2 , Figure 3 and Figure 4A limiting groove 23 is provided on one side of the track roller body 1 shown. A limiting block 28 is fixed to the inner wall of the blocking ring 24. The limiting block 28 is placed inside the limiting groove 23 to assist in limiting and calibrating the position of the blocking ring 24. By setting the limiting block 28 and the limiting groove 23, the limiting block 28 can be placed inside the limiting groove 23 to assist in limiting the blocking ring 24. At the same time, the limiting block 28 can be inserted into the limiting groove 23 to quickly position the blocking ring 24, so that the blocking ring 24... The inner wall of the hole on the ring 24 quickly aligns with the inner wall of the threaded groove 21, improving the convenience and efficiency of personnel in installing and adjusting the blocking ring 24. A circular plate 27 is fixedly connected to one side of the blocking ring 24. The circular plate 27 has multiple anti-slip protrusions on the side of the circular plate 27 closest to the blocking ring 24. By setting the circular plate 27, a point of leverage can be provided for personnel to manually move the blocking ring 24, so that personnel can manually pull the circular plate 27 to move the blocking ring 24, improving the convenience and stability of personnel manually pulling the blocking ring 24.

[0033] Figure 2 , Figure 3 and Figure 4 Multiple support blocks 25 are fixed to the inner side of the interception ring 24 shown. The surface of the support block 25 is trapezoidal. By setting the support block 25, the interception ring 24 can be supported and reinforced, reducing the possibility of tilting or deformation of the interception ring 24 when it is squeezed by the track. An auxiliary ring 26 is fixed to the surface of the interception ring 24. The surface of the auxiliary ring 26 is higher than that of the interception ring 24. By setting the auxiliary ring 26, when the track accidentally flips over the surface of the interception ring 24 during the left and right displacement, the auxiliary ring 26 can intercept the flipped track a second time, further improving the interception effect of the track.

[0034] Figure 2 , Figure 3 and Figure 4 The intercepting ring 24 shown has multiple reinforcing ribs 210 inside, which are made of nickel alloy. By setting the reinforcing ribs 210, the strength of the intercepting ring 24 can be increased, reducing the possibility of the intercepting ring 24 breaking under stress. A wear-resistant plate 29 is fixed to the side of the intercepting ring 24 near the track roller body 1. The wear-resistant plate 29 is made of high manganese steel. By setting the wear-resistant plate 29, the wear-resistant plate 29 can replace the intercepting ring 24 in contact with the edge of the track, reducing the wear caused by the track to the intercepting ring 24 during operation, and further improving the wear resistance and service life of the intercepting ring 24.

[0035] Working principle: First, manually move the blocking ring 24 to a position where it fits on the surface of the track roller body 1. Continue moving the blocking ring 24 left and right along the surface of the track roller body 1. When the blocking ring 24 moves to a position that is close to or in contact with the edge of the track, the inner wall of the hole on the blocking ring 24 coincides with the inner wall of any threaded groove 21. At this time, use a tool to screw the bolt 22 into the blocking ring 24 and the threaded groove 21 to fix the position of the blocking ring 24. The blocking ring 24 is fixed in position and placed at the edge of the track to intercept and limit it, thereby achieving the anti-track skipping treatment.
