Description

Technical Field

[0001] This application relates to the field of tracks, and in particular to a high-temperature resistant track and its robot chassis. Background Technology

[0002] The track is a flexible chain driven by the drive sprocket and surrounding the drive sprocket, road wheels, support wheels, and track rollers. The track consists of track plates and track pins. The track plates and track pins are crucial for the reliable operation of the robot. The track pins are made of special materials to ensure a firm connection to the track plates even under complex working conditions, forming a stable track chain. Through holes at both ends of the track plates, they precisely mesh with the drive sprocket, and the guide teeth in the middle effectively prevent the track from slipping off when the robot turns or moves on uneven ground, ensuring stable operation.

[0003] Currently, most tracks are fixed, achieved by welding the track plates together. Under normal operation, these welded tracks provide reliable support for the equipment. However, when track plates wear down, maintenance personnel need to use specialized tools to cut off the worn track plates and then weld new ones onto the track. This process is complex, time-consuming, and results in prolonged equipment downtime, significantly reducing the convenience of maintenance. Utility Model Content

[0004] To address the problem that repairing welded fixed tracks requires specialized tools to cut off the old track plates and then weld new ones after wear, which is cumbersome and time-consuming, this application provides a high-temperature resistant track and its robot chassis.

[0005] Firstly, the high-temperature resistant track provided in this application adopts the following technical solution:

[0006] A high-temperature resistant track includes a track chain with multiple T-blocks evenly spaced on it. Each T-block has a track plate and a replacement assembly for easy replacement of the track plates. The replacement assembly includes two track holes symmetrically formed on the track plate, two positioning holes symmetrically formed on the T-block, and two track pins that cooperate with the track holes and positioning holes. The track plates and T-blocks are fastened together by the track pins.

[0007] By adopting the above technical solution, the track plate and the T-block are detachably connected by track pins, which facilitates quick replacement when the track plate is worn or damaged, without the need for destructive removal of surrounding parts, significantly reducing maintenance difficulty and time costs, and improving the ease of use of the equipment.

[0008] Optionally, the edges of the track plates are rounded.

[0009] By adopting the above technical solution, the rounded edges of the track plates can effectively reduce stress concentration caused by sharp edges during operation, thereby improving the structural strength and durability of the track plates.

[0010] Optionally, the surface of the track plate is provided with a tungsten carbide coating.

[0011] By adopting the above technical solution, a tungsten carbide coating is applied to the surface of the track plates, which significantly improves their wear resistance and high-temperature resistance. This allows the track structure to maintain stable operation even in high-temperature environments, while extending the service life of the track plates and reducing the frequency of replacement due to wear.

[0012] Secondly, the robot chassis provided in this application adopts the following technical solution:

[0013] A robot chassis includes two sets of high-temperature resistant tracks and a suspension structure. The suspension structure is disposed inside the high-temperature resistant tracks and includes a drive wheel, a guide wheel, two trailing wheels, multiple support wheels, and a support wheel. The drive wheel is located at the inner front of the high-temperature resistant tracks, the guide wheel is located at the inner rear of the high-temperature resistant tracks, the two sets of trailing wheels are located at the inner upper part of the high-temperature resistant tracks, the multiple support wheels are located at the inner lower part of the high-temperature resistant tracks, and the support wheel is disposed below the guide wheel. The drive wheel, guide wheel, trailing wheel, and support wheel are respectively mounted on the robot chassis. Each axle of the multiple sets of support wheels is provided with a shock-absorbing component for absorbing the impact force of the support wheels.

[0014] By employing the above technical solution, the coordinated use of the drive wheel, guide wheel, trailing wheel, support wheel, and track roller ensures the stable operation of the high-temperature resistant track. The drive wheel propels the high-temperature resistant track forward, the guide wheel ensures the correct track direction, the trailing wheel prevents the track from sagging, the support wheel bears the weight of the robot chassis, and the support wheel also supports the track to prevent derailment due to vibration. By installing shock-absorbing components on the axles of the support rollers, the impact force of the support rollers can be absorbed, thus improving the overall operating efficiency and stability of the robot.

[0015] Optionally, the shock absorption assembly includes a track support frame fixed to the axle of the support roller, a first connecting hole in the middle of the track support frame, a second connecting hole in the track support frame away from the support roller, a first connecting rod rotating on the first connecting hole, a second connecting rod fixed to the robot chassis, a third connecting rod fixed to the robot chassis, and a shock absorber disposed above the support roller. One end of the shock absorber rotates on the first connecting rod with the first connecting hole, the second connecting hole rotates on the second connecting rod, and the other end of the shock absorber rotates on the third connecting rod.

[0016] By adopting the above technical solution, the shock absorption components effectively improve the robot's stability and adaptability. The track support frame is fixedly connected to the axle of the support roller, and through the first and second connecting holes respectively, it engages with the first and second connecting rods to form a stable connection structure, ensuring that the support roller can evenly bear the weight of the robot chassis during operation. The two ends of the shock absorber are rotatably connected to the first and third connecting rods respectively, which can absorb the vibration energy of the support roller when the robot chassis is subjected to impact or bumps, thereby reducing the impact of vibration on the overall performance of the robot and improving the robot's operational stability under complex terrain conditions.

[0017] Optionally, a support frame is fixed on the axle of the support wheel, and a square groove is provided on the track support frame near the guide wheel to prevent the support frame from colliding with the track support frame. The support frame is sleeved on the outside of the square groove.

[0018] By adopting the above technical solution, the receiving frame is fitted onto the outside of the square groove and fixedly connected to the axle of the support wheel. When the robot traverses uneven and complex terrain, it can avoid collisions between the track support frame near the guide wheel axle and the receiving frame, thus preventing damage to parts.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By setting replacement components on the T-block, and utilizing the track holes and positioning holes to cooperate with the track pins, the track shoes can be quickly removed and installed, which significantly improves the replacement efficiency of the track shoes and reduces maintenance time and costs;

[0021] 2. When the robot chassis is subjected to impact or bumps, the shock absorption components can absorb the vibration energy of the support rollers, thereby reducing the impact of vibration on the overall performance of the robot and improving the robot's operational stability under complex terrain conditions.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] In one aspect, embodiments of this application disclose a high-temperature resistant track.

[0031] Reference Figure 1 A high-temperature resistant track includes a track chain 1, wherein the track chain 1 adopts a multi-link structure to improve the flexibility and adaptability of the high-temperature resistant track. Multiple T-blocks 2 are evenly spaced and firmly fixed on the track chain 1. Each T-block 2 is correspondingly provided with a track plate 3.

[0032] Reference Figure 2 The edges of the track plate 3 are rounded, which effectively reduces stress concentration caused by sharp edges during operation, thereby improving the structural strength and durability of the track plate 3. The track plate 3 is made of silicon carbide, which has extremely high heat resistance and wear resistance. A tungsten carbide coating is applied to the surface of the track plate 3, which can improve the wear resistance of the high-temperature track surface.

[0033] Reference Figure 2To facilitate the replacement and maintenance of damaged track shoes 3, a dedicated replacement assembly 4 is provided on each T-block 2. The replacement assembly 4 includes two track holes 401, two positioning holes 402, and two track pins 403. The two track holes 401 are symmetrically located on the track shoes 3, and correspondingly, the two positioning holes 402 are also symmetrically located on the T-blocks 2. Through these two track pins 403, the track shoes 3 are tightly connected to the T-blocks 2, thereby constructing a high-temperature resistant track structure that facilitates the replacement of the track shoes 3.

[0034] The track pin 403 is made of a nickel-based alloy, which has excellent high-temperature strength and oxidation resistance, ensuring the reliability of the connecting parts at high temperatures. In addition, a molybdenum disulfide lubricating layer is added between the pin and the track plate 3 to reduce friction and wear through self-lubrication.

[0035] The implementation principle of a high-temperature resistant track according to an embodiment of this application is as follows: To facilitate convenient replacement and maintenance of the track pads 3, a replacement component 4 is provided on the T-block 2. When the track pad 3 is damaged, the track pin 403 can be easily removed, and the track pad 3 can be quickly replaced. In addition, the track pad 3 is made of silicon carbide material, which has extremely high heat resistance and wear resistance, and a tungsten carbide coating is provided on the surface of the track pad 3, which can improve the wear resistance of the surface of the high-temperature resistant track and ensure the stability and durability of the high-temperature resistant track in high-temperature environments.

[0036] Secondly, embodiments of this application disclose a robot chassis structure.

[0037] Reference Figure 3 A robot chassis employs two sets of high-temperature resistant tracks. The high-temperature resistant tracks have an internal suspension structure 5, which includes a drive wheel 6, guide wheels 7, two trailing wheels 8, multiple support wheels 9, and support wheels 10. The drive wheel 6 is located at the front inner side of the high-temperature resistant track to drive its movement; the guide wheels 7 are located at the rear inner side of the high-temperature resistant track to guide it; two sets of trailing wheels 8 are located at the upper inner side of the high-temperature resistant track to prevent sagging; multiple sets of support wheels 9 are located at the lower inner side of the high-temperature resistant track to support the robot chassis; and shock-absorbing components 11 are installed on each of the support wheels 9 to absorb the impact force generated during movement.

[0038] Reference Figure 3Both the drive wheel 6 and its axle are made of nickel-based alloy and feature heat dissipation holes to reduce thermal stress concentration. Furthermore, the drive wheel 6 is fixedly connected to its axle, which is connected to a drive source mounted on the robot chassis, enabling the drive source to rotate the drive wheel 6 and provide power. The drive wheel 6 is engaged with the T-block 2, allowing its rotation to drive the high-temperature track. Moreover, by embedding the protrusion of the T-block 2 into the drive wheel 6, slippage or tooth disengagement between the high-temperature track and the drive wheel 6 is prevented, improving the reliability of the high-temperature track drive.

[0039] Reference Figure 3 Both the guide wheel 7 and its axle are made of nickel-based alloy and feature heat dissipation holes to reduce thermal stress concentration. One end of the guide wheel 7's axle is fixed to the robot chassis, and the guide wheel 7 is rotatably connected to its axle. The protrusion of the T-block 2 is embedded in the guide wheel 7, and the T-block 2 meshes with the guide wheel 7, causing the rotating high-temperature track to drive the guide wheel 7 to rotate around its axle under the meshing action. The guide wheel 7 effectively guides the direction of the high-temperature track during robot turning or movement, preventing the track from deviating or detaching.

[0040] Reference Figure 3 The towing wheel 8 and its axle are both made of nickel-based alloy and designed with heat dissipation holes to reduce thermal stress concentration. Furthermore, one end of the axle of the towing wheel 8 is fixed to the robot chassis, and the towing wheel 8 is rotatably connected to its axle. The protrusion of the T-block 2 is embedded in the towing wheel 8, and the T-block 2 meshes with the towing wheel 8, allowing the rotation of the high-temperature track to drive the towing wheel 8 to rotate around its axle under meshing action. By positioning the towing wheel 8 on the inner upper side of the high-temperature track, sagging during operation is effectively prevented, ensuring the high-temperature track remains taut and guaranteeing the normal operation of the robot.

[0041] Reference Figure 3 Both the support roller 9 and its axle are made of nickel-based alloy and feature heat dissipation holes to reduce thermal stress concentration. Furthermore, the support roller 9 is rotatably connected to its axle, with one end of the axle fixed to the robot chassis. The protrusion of the T-block 2 is embedded in the support roller 9, and the T-block 2 meshes with the support roller 9, allowing the rotation of the high-temperature track to drive the support roller 9 to rotate around its axle under the meshing action. By positioning the support roller 9 on the inner lower side of the high-temperature track, the weight of the robot chassis is evenly distributed, improving operational stability.

[0042] Reference Figure 3The support wheel 10 is positioned below the guide wheel 7. Both the support wheel 10 and its axle are made of nickel-based alloy and feature heat dissipation holes to reduce thermal stress concentration. Furthermore, the support wheel 10 is rotatably connected to its axle, with one end of the axle fixed to the robot chassis. The protrusion of the T-block 2 is embedded in the support wheel 10, and the T-block 2 meshes with it, allowing the rotation of the high-temperature track to drive the support wheel 10 to rotate around its axle under the meshing action.

[0043] Reference Figure 4 Shock-absorbing components 11 are installed on the axles of multiple support rollers 9 to absorb the impact force generated when the robot travels on uneven surfaces. The shock-absorbing components 11 include a track support frame 1101, a first connecting hole 1102, a second connecting hole 1103, a first connecting rod 1104, a second connecting rod 1105, a third connecting rod 1106, and a shock absorber 1107. The shock absorber 1107 is a high-temperature resistant shock absorber.

[0044] Reference Figure 4 The track support frame 1101 is fixed to the axle of the support roller 9. A first connecting hole 1102 is located in the middle of the track support frame 1101, and a second connecting hole 1103 is located at the end of the track support frame 1101 away from the axle of the support roller 9. A first connecting rod 1104 is fixed to the robot chassis, and a third connecting rod 1106 is fixed to the robot chassis. One end of the shock absorber 1107 rotates coaxially with the first connecting hole 1102 on the first connecting rod 1104, and with the second connecting hole 1103 on the second connecting rod 1105. The other end of the shock absorber 1107 rotates coaxially with the third connecting rod 1106.

[0045] When the robot travels on uneven terrain such as rough or potholed surfaces, the support wheels experience severe vibrations due to the undulating road surface. This is where the shock absorption component 11 plays a crucial role. First, the severe vibrations are transmitted to the track support frame 1101 via the support wheel 9 axle. The movement of the track support frame 1101 causes the internal springs of the shock absorber 1107 to contract or extend, effectively buffering and absorbing the impact force generated by the vibrations. This significantly reduces the vibration energy transmitted to the robot's chassis. This not only prevents damage to the robot's internal precision components due to vibration, extending the equipment's lifespan, but also ensures the robot's operational stability, allowing it to move smoothly even on complex terrain, thus improving its operational accuracy and reliability.

[0046] Reference Figure 5 A support frame 12 is fixed on the axle of the support wheel 10. A square groove 13 is provided on the track support frame 1101 near the guide wheel 7, and the support frame 12 is fitted on the outside of the square groove 13.

[0047] Reference Figure 3 and Figure 5 When the robot travels on complex terrain, the support wheel 10 can provide real-time support and guidance for the high-temperature resistant track, ensuring that the track always stays on the correct running trajectory. This effectively reduces the risk of the high-temperature resistant track deviating, jamming, or even falling off, greatly improving the reliability of the robot's operation. Furthermore, by fitting the support frame 12 on the axle of the support wheel 10 onto the outside of the square groove 13, the robot can avoid collisions between the track support frame 1101 near the guide wheel 7 axle and the support frame 12 when traversing uneven and complex terrain, thus preventing damage to parts.

[0048] The implementation principle of a robot chassis according to an embodiment of this application is as follows: the drive wheel 6 drives the high-temperature resistant track forward, the guide wheel 7 ensures the correct guidance of the high-temperature resistant track, the trailing wheel 8 prevents the high-temperature resistant track from sagging, the support wheel 9 bears the weight of the robot chassis, and the support wheel 10 also supports the high-temperature resistant track to prevent derailment when the high-temperature resistant track vibrates. By setting a shock-absorbing component 11 on the axle of the support wheel 9, the impact force of the support wheel 9 can be absorbed, thus improving the overall operating efficiency and stability of the robot.
