Description

Technical Field

[0001] The utility model relates to the technical field of track rollers, and more specifically, to an anti-derailment track roller. Background Art

[0002] Track rollers are an important component widely used in engineering machinery. They are mainly used to support the weight of the machinery and roll on the track to prevent the track from derailing and lateral slipping. Existing track rollers mainly use limit columns set on both sides of the flange next to the limit groove to increase the height of the flange. In theory, the purpose of preventing derailment is to increase the diameter of the flange. However, in fact, the diameter of the flange is restricted by the track plate and the track chain. Increasing the diameter will result in the problem of not being able to install it, and there is a problem that the expected effect cannot be achieved.

[0003] After searching, a Chinese patent with announcement number CN220220956U discloses a crawler crane track anti-derailment roller. The utility model uses a roller adjustment frame installed on a walking frame to dynamically adjust the interval between the roller and the track chain on the crawler, so that the roller is always in contact with the track chain, effectively avoiding the problem of roller derailment. At the same time, an additional wheel that can be expanded and adjusted on the roller is used to dynamically adjust the diameter of the roller, so that the roller is always in contact with the track chain, further enhancing the use effect and avoiding the problem of roller derailment.

[0004] When the above-mentioned supporting wheel is in use, the flange on the wheel plate is always in contact with the track chain through the second telescopic mechanism. The second telescopic mechanism mainly includes a second sleeve and a second set of rods, and a second return spring is placed in the second sleeve and the second set of rods. However, the stability between the track chain and the flange is poor, and the flange is prone to shaking under the action of the second return spring, resulting in poor use effect.

[0028] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0029] Referring to the attached Figure 1-6 drawing of the specification, the derailment-proof idler of this embodiment includes an idler body 1 and a rotating shaft 2. One end of the rotating shaft 2 penetrates through the idler body 1 and is movably connected to it through a bearing. A second empty groove 10 is formed inside the idler body 1. An anti-derailment structure 3 is arranged inside the second empty groove 10. The anti-derailment structure 3 includes a limiting column 301, a semi-cylindrical head 302, a sealing sleeve 303, a circular plate 304, and a spring 305. One end of the limiting column 301 penetrates through the idler body 1 and is fixedly connected to the semi-cylindrical head 302. The sealing sleeve 303 is fixedly sleeved on the limiting column 301, and the outer side of the sealing sleeve 303 is in contact with the idler body 1. One side of the circular plate 304 is fixedly connected to the limiting column 301. The two ends of the spring 305 are respectively fixedly connected to the circular plate 304 and the idler body 1. The number of the anti-derailment structures 3 is several. A sliding rod 306 is movably arranged inside the limiting column 301, and one end of the sliding rod 306 passes through the circular plate 304 and the spring 305.

[0030] Further, a first empty groove 9 is formed inside the idler body 1. Connecting pipes 11 communicating with the outside are arranged on both the first empty groove 9 and the second empty groove 10, and both of the two connecting pipes 11 are fixedly connected to the idler body 1. Valves 12 are fixedly installed on both of the two connecting pipes 11. A protective component is arranged at the middle position on the outer side of the idler body 1. The protective component includes a threaded protective ring 5, two external thread sleeves 6, and a plurality of anti-slip strips 7. The two external thread sleeves 6 are fixedly connected to the opposite sides of the idler body 1, and both of the two external thread sleeves 6 are threadedly connected to the threaded protective ring 5. The plurality of anti-slip strips 7 are fixedly sleeved on the threaded protective ring 5.

[0031] Among them, open the valve 12 on the connecting pipe 11 communicating with the first empty groove 9, connect the output end of the oil injection pump to this connecting pipe 11, thereby injecting lubricating oil into the first empty groove 9, and close this valve 12 after injecting the lubricating oil to ensure that the lubricating oil will not flow out from the connecting pipe 11. The lubricating oil can reduce friction, reduce wear, and improve the service life of the idler body 1 and the rotating shaft 2. Rotate the threaded protective ring 5 to make it horizontally move on the external thread sleeve 6, and protect the two connecting pipes 11 and the two valves 12 through the threaded protective ring 5 to prevent external blunt objects from damaging them. The structure is simple and convenient to use. At the same time, the plurality of anti-slip strips 7 can increase the friction between the human hand and the threaded protective ring 5.

[0032] Furthermore, baffles 8 are embedded and installed on both sides of the carrier roller body 1, and the two baffles 8 are fixedly sleeved on the rotating shaft 2. Through the two baffles 8, it is convenient to seal both sides of the carrier roller body 1.

[0033] Furthermore, fixing seats 4 are movably arranged on the opposite sides of the two baffles 8, and the two fixing seats 4 are movably sleeved on the rotating shaft 2. Through the two fixing seats 4, it is convenient to connect the rotating shaft 2.

[0034] The usage method of this embodiment is as follows:

[0035] During use, open the valve 12 on the connecting pipe 11 communicating with the second empty slot 10, and connect the output end of the air inflation pump to the connecting pipe 11, so as to inject inert gas into the second empty slot 10. After filling the gas, close the valve 12 to ensure that the inert gas will not flow out from the connecting pipe 11. When the inert gas in the second empty slot 10 gradually increases, the inert gas squeezes the multiple circular plates 304, so that the multiple limit posts 301 and the multiple semi-cylindrical heads 302 move out of the interior of the carrier roller body 1 to achieve the purpose of preventing derailment. At the same time, the multiple sealing sleeves 303 can improve the sealing performance between the multiple limit posts 301 and the carrier roller body 1, effectively preventing the leakage of inert gas. The structure is simple, the overall stability is strong, and the use effect is good. When filling with inert gas, the circular plate 304 can drive the spring 305 to stretch and generate elastic potential energy. When it is necessary to release the limit of the carrier roller body 1, just open the valve 12 corresponding to the second empty slot 10 and discharge the inert gas in the second empty slot 10. After the inert gas is discharged, the spring 305 will rebound and drive the limit post 301 and the semi-cylindrical head 302 to move into the second empty slot 10 to release the limit, which is convenient for maintenance. And the sliding rod 306 can limit the circular plate 304 and the spring 305.
