Description

Technical Field

[0001] This utility model relates to a double-track guided anti-detachment track roller structure, specifically a double-track guided anti-detachment track roller structure, belonging to the field of track roller technology. Background Technology

[0002] Track rollers are an important component in the chassis system of tracked machinery (such as excavators and bulldozers). Track rollers provide support and guidance for the tracks. They are mounted on the frame to support the tracks and keep them on the correct running track, ensuring that the tracks can rotate smoothly around the drive wheels, idler wheels, and other components, thus making the entire equipment travel stably.

[0003] A novel track track carrier roller is disclosed in Chinese patent application publication CN215475439U. This device has a simple structure, can make the track track roller bear force evenly, extend the service life of the track track roller, reduce the operating cost of the equipment, reduce the time wasted by operators in cleaning up soil, and reduce labor costs, thus having good practicality.

[0004] However, during the implementation of the aforementioned patented technical solution, the installation location of the track roller is often clogged and rusted due to the presence of mud and soil. Tracked machinery often operates in harsh environments, with mud, soil, stones, and other debris frequently present on the track. Existing track rollers are mostly bolted to the frame, and these bolts are mostly exposed, making it easy for mud and sewage to enter the bolt gaps, leading to blockage and rust. This makes it difficult to remove the installation bolts during subsequent maintenance or replacement of the track roller, affecting the maintenance efficiency of the track roller.

[0005] Therefore, a dual-track guided anti-detachment chain roller structure is proposed here. Utility Model Content

[0006] This utility model proposes a double-track guided anti-detachment chain roller structure to solve the problem in the prior art where the installation bolts of the chain roller are easily blocked and rusted due to mud and soil at the installation position.

[0007] This utility model is achieved through the following technical solution: a double-track guide anti-detachment chain wheel structure, including a mounting frame, an anti-detachment chain wheel is provided on the outside of the mounting frame, and a mounting block is rotatably connected to one end of the anti-detachment chain wheel near the mounting frame, the mounting block being adapted to the mounting frame;

[0008] The mounting frame is provided with a protective mechanism on its exterior. The protective mechanism includes a sealing frame fixed to the outer surface of the mounting frame, a support base fixed to the outer surface of the mounting frame, and two mounting bolts threaded to the inner wall of the mounting frame. A sealing cover is slidably connected to the outer surface of the sealing frame, and a limit block is fixed to the outer surface of the sealing cover. A limit rod is slidably connected to the inner wall of the support base, and the limit rod is adapted to the limit block.

[0009] Specifically, a fixing ring is fixed to the outer surface of the limiting rod, and the fixing ring is slidably connected to the inner wall of the support base. A first spring is fixed to the outer surface of the fixing ring, and the end of the first spring away from the fixing ring is fixed to the inner wall of the support base. The first spring is always in a compressed state, so that the limiting rod is always subjected to elastic force in the direction close to the sealing frame.

[0010] Specifically, the inner wall of the sealing cover is fixed with two symmetrical sliders, both of which are slidably connected to the inner wall of the sealing frame. The sealing frame has two grooves that are adapted to the sliders. The sliding of the sliders in the grooves on the sealing frame guides the movement of the sealing cover.

[0011] Preferably, the mounting frame is provided with a scraping mechanism on its exterior. The scraping mechanism includes a scraping plate and a fixing frame fixed to the outer surface of the mounting frame. Two fixing cylinders are fixed to the upper surface of the fixing frame. Sliding rods are slidably connected to the inner walls of the two fixing cylinders. The top ends of the two sliding rods are fixed to the bottom surface of the scraping plate. The scraping plate can scrape off soil and other debris adhering to the anti-detachment track roller, preventing soil, stones and other debris from getting stuck between the anti-detachment track roller and the track.

[0012] Furthermore, a second spring is fixed to the inner wall of each of the two fixed cylinders. The top ends of the two second springs are respectively fixed to the bottom ends of the two sliding rods. The second springs can buffer the scraping plate when it scrapes the anti-detachment track wheel, preventing stones and other debris from damaging the scraping plate and the anti-detachment track wheel.

[0013] Preferably, the inner wall of the mounting bracket is fixed with two symmetrical positioning strips, both of which are slidably connected to the mounting block, and the positioning strips serve to position the mounting block during installation.

[0014] This utility model provides a double-track guided anti-detachment chain roller structure, which has the following beneficial effects:

[0015] 1. This double-track guided anti-detachment track roller structure, through the setting of the protection mechanism, can seal and protect the mounting bolts after the anti-detachment track roller is installed, preventing mud, sewage and other debris from entering the mounting bolt gaps. It is suitable for the complex working environment of tracks, and prevents the mounting bolt installation position from being blocked or rusted. Even after long-term use, the mounting bolts can still be easily disassembled, which facilitates the disassembly and maintenance of the anti-detachment track roller.

[0016] 2. This dual-track guide anti-detachment track roller structure, through the setting of the scraping mechanism, scrapes off soil clods and other debris adhering to the anti-detachment track roller when it rotates, preventing soil clods, stones and other debris from getting stuck between the anti-detachment track roller and the track, thus facilitating the support and guidance of the anti-detachment track roller for the track. At the same time, the setting of the second spring can play a buffering role when the scraping plate scrapes the anti-detachment track roller, preventing stones and other debris from damaging the scraping plate and the anti-detachment track roller.

[0026] Please refer to this carefully. Figure 4 A fixing ring 37 is fixed to the outer surface of the limiting rod 36. The fixing ring 37 is slidably connected to the inner wall of the support base 35. A first spring 38 is fixed to the outer surface of the fixing ring 37. The end of the first spring 38 away from the fixing ring 37 is fixed to the inner wall of the support base 35. The first spring 38 is always in a compressed state, so that the limiting rod 36 is always subjected to elastic force in the direction close to the sealing frame 32.

[0027] Please refer to this carefully. Figure 3 The inner wall of the sealing cover 33 is fixed with two symmetrical sliders 39. Both sliders 39 are slidably connected to the inner wall of the sealing frame 32. The sealing frame 32 has two grooves that are adapted to the sliders 39.

[0028] Please refer to this carefully. Figure 5 The mounting frame 1 is equipped with a scraping mechanism 4 on its exterior. The scraping mechanism 4 includes a scraping plate 42 and a fixing frame 41 fixed to the outer surface of the mounting frame 1. Two fixing cylinders 43 are fixed to the upper surface of the fixing frame 41. Sliding rods 44 are slidably connected to the inner walls of the two fixing cylinders 43.
