Description

Technical Field

[0001] This invention discloses a tracked chassis, and more particularly relates to a highly adaptable and adjustable tracked chassis. Background Technology

[0002] Tracked chassis are mechanical engineering equipment, mostly used in small and medium-sized light industry and small and medium-sized construction machinery industries. Light industry generally refers to agricultural machinery weighing one to four tons. Tracked chassis are roughly divided into two types according to the track material: rubber track chassis and steel track chassis. For use in harsher environments or outdoors, steel track chassis are generally more robust and durable and are therefore more commonly used. A tracked chassis generally consists of a track assembly, chassis, drive wheels, guide wheels, track rollers, and carrier rollers.

[0003] The function of track rollers is to support the tracks and prevent the tracks from becoming too slack when driven to the upper part of the chassis. In existing technologies, track rollers are generally fixed and their number cannot be increased. There is a difference between single track rollers and multiple track rollers. Tanks, which require high mobility and rapid movement, generally use multiple track rollers, while engineering machinery mostly uses a single track roller. A single track roller avoids the weight burden of additional track rollers, which helps improve adaptability. Engineering equipment has a slower rotation speed and can adapt to slow climbing on different terrains. Setting up multiple track rollers distributes the load-bearing pressure on the upper section of the track, and multiple support points greatly reduce the swaying amplitude of the track between the upper and lower sections, reducing lateral vibration and derailment risk at high speeds. Although a single track roller improves mobility and adapts to slow climbing on different terrains, it is slow and the swaying amplitude is greater on normal roads, making it easy to derail. Therefore, this application proposes a new solution that allows the track rollers to be adjusted and switched, making it better suited for use in different environments. Summary of the Invention

[0004] The purpose of this invention is to provide a highly adaptable and adjustable tracked chassis in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a highly adaptable and adjustable tracked chassis, comprising a chassis support, a track assembly, a drive wheel, a guide wheel, a support wheel, and a track carrier wheel. The chassis support is provided with a track carrier wheel seat rotatably connected to the track carrier wheel. The chassis support is provided with a plurality of support wheels on both sides of the track carrier wheel. A movable rod is slidably connected to the chassis support. The track carrier wheel seat is slidably connected to the chassis support. The movable rod is provided with an abutment block that abuts against the track carrier wheel seat and pushes the track carrier wheel seat upward. The abutment block and the track carrier wheel seat have an inclined surface. The chassis support is provided with a fixing member rotatably connected to the support wheels. The fixing member is slidably connected to the chassis support. A sleeve is slidably connected to the movable rod. Two connecting rods are rotatably connected to both sides of the sleeve, and the end of the connecting rod away from the sleeve is rotatably connected to the fixing member. The chassis support is provided with a drive assembly for driving the track carrier wheel and the support wheels to move.

[0006] The drive assembly includes a cylinder 1 mounted on a chassis bracket, a push block slidably connected to the cylinder 1 mounted on the chassis bracket, a second abutting block 2 abutting against the push block mounted on the moving rod, the abutting surface of the second abutting block and the push block being inclined, and an adjustment assembly for switching the push block and the moving rod and the sleeve connected on the chassis bracket.

[0007] Preferably, the adjustment assembly includes a blocking block disposed on the chassis support, the blocking block being located at the roller seat, and the blocking block abutting the first abutting block and preventing the abutting block and the moving rod from continuing to move, the sleeve being staggered with the moving rod, and the moving rod abutting the pushing block first, and a spring being provided between the second abutting block and the moving rod for supporting the second abutting block, and the elastic force of the spring being less than the interaction force between the first abutting block and the first cylinder.

[0008] Preferably, a second spring is provided between the sleeve and the chassis support, and the bottom of the push block, the sleeve and the moving rod are all in contact with the chassis support, and the push block is also in a state of being sleeved outside the moving rod.

[0009] Preferably, the support wheels are connected by connectors, and the chassis bracket is provided with guide grooves for guiding the movement of the bottom fixing parts of the support wheels. The guide grooves at the bottom of the support wheels are staggered. The guide grooves are provided with abutting blocks three that abut against the fixing parts and push the fixing parts and support wheels upward. The number of abutting blocks three and guide grooves corresponds to the number of support wheels.

[0010] Preferably, the chassis support has protrusions on both sides of the moving rod that abut against the pushing block, and the protrusions are slidably connected to the chassis support. A rotating rod is rotatably connected to the bottom of the protrusion, and the middle of the rotating rod is rotatably connected to the chassis support. A limiting block is rotatably connected to the other end of the rotating rod that abuts against the moving rod and prevents the moving rod from moving backward.

[0011] Preferably, the rotating rod is provided with a spring three at the bottom of the protrusion on one side, and the protrusion is spherical.

[0012] Preferably, the chassis support is provided with a detachable limiting member at the blocking block, and the blocking block is engaged with the limiting member. The moving rod is provided with a fourth abutment block at the rear end of the first abutment block, which is consistent with the first abutment block. The guide groove has a convex cross section, and the end of the guide groove is provided with a slot at the rear end of the third abutment block to accommodate the moving and passing-through of the fixing member.

[0013] Preferably, the chassis support is provided with a detachable limiting component at the blocking block, and the chassis support is slidably connected to the parts on both sides of the moving rod that abut against the pushing block. The bottom of the supporting block is provided with a cylinder two for pushing the supporting block upward, and the pushing block is slidably connected to the piston of the cylinder one. A spring four is provided between the moving rod and the chassis support.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Firstly, when this device is used on engineering equipment, if the distance is short and there is no need to tow the equipment, after traveling on a relatively flat road surface, the switch of cylinder one in the control room can be turned on to inflate cylinder one and drive the connected push block to move together. The push block will abut against the abutting block two on the moving rod, and the abutting block two will drive the moving rod to move synchronously. The abutting block one on the moving rod moves to abut against the bottom of the roller seat, and at the same time, the roller seat is pushed upward along the slope of the bottom of the roller seat, pushing the upper end of the track assembly to tighten it a bit and the entire track assembly is slightly tightened, thus better adapting to the flat road, with a small track movement swing amplitude and a fast movement speed. At the same time, the guide wheel can also be moved by controlling it, working together with the track roller to make the track fit more tightly and reduce the swing amplitude.

[0016] Secondly, the cylinder drives the push block to move and abut against the abutment block 2. The abutment block 2 drives the moving rod to move together and pushes the abutment block 1 to push the roller seat upward. The track roller rises synchronously to support the track assembly. The abutment block 1 abuts against the blocking block. Through the blocking of the blocking block and the pushing of the push block, the abutment block 2 moves downward and compresses the spring 1. At this time, the push block will pass over the abutment block 2 and fit against the sleeve, and continue to move to drive the sleeve forward. When the sleeve moves, the connecting rod moves forward and pushes the fixing part along the guide groove, and drives the support wheel to move synchronously. Through the pushing of the abutment block 3 and the connecting rod, the fixing part moves along the guide groove to the abutment block 3. At the same time, the support wheel moves up and abuts against the track assembly, so that the support wheel and the track roller jointly support the track assembly, reducing the sway amplitude of the track on the side of the track roller. This makes the track move more stably and smoothly, and disperses the load pressure on the upper section of the track.

[0017] Thirdly, since the pushing block cannot overcome the elastic force of spring one, the moving rod can be synchronized. Then, after the abutting block one abuts against the blocking block, the interaction force between the blocking block and the pushing block is greater than the elastic force of spring one, which can overcome the elastic force of spring one. After spring one is compressed, the connection can be switched to ensure that the support wheel also moves upward, and the support force is increased. Through a simple mechanism, the connection between the pushing block, the moving rod and the sleeve can be switched. Secondly, it can ensure that the track roller moves upward first, and then drive the support wheel to move upward, avoiding the situation where the track separates from the track roller due to the support of the support wheel. By moving upward alternately back and forth, the support is achieved together, making the support effect better.

[0018] Fourth, after the pushing block presses the abutment block two downwards, the pushing block moves along the side of the moving rod and abuts against the protrusion and pushes downwards along the protrusion. At the same time, the spring three is compressed and the rotating rod at one end of the protrusion is pushed downwards, causing the rotating rod to rotate along the middle. This causes the end of the rotating rod away from the protrusion to move upwards and simultaneously drive the limiting block to move upwards, thereby blocking the moving rod and preventing the moving rod and abutment block one from being pushed and supported by the pushing block. This prevents the abutment block one from being pushed back to its original position due to the pressure of the roller seat and the track roller and the oscillation of the track.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] A highly adaptable and adjustable tracked chassis, such as Figures 1-8As shown, the system includes a chassis support 1, a track assembly 2, a drive wheel 3, a guide wheel 4, a support roller 5, and a track carrier roller 6. The chassis support 1 has a track carrier seat 7 rotatably connected to the track carrier roller 6. Under normal use, the track carrier seat 7 is fixed, and the track carrier roller 6 is rotatably connected to it, preventing movement and thus maintaining a fixed track height. Even if the guide wheel 4 adjusts the track tension via a cylinder within the chassis support 1, the track's sway amplitude is still significant when it reaches the top. While slow movement is adaptable during operation, accelerating the movement can easily lead to track derailment. Furthermore, due to the significant weight of the track, derailment can cause considerable damage. Outdoor installation is difficult and inconvenient, and movement is slow and requires caution. Therefore, when movement is necessary, a trailer is usually used to transport the equipment to the work site, and then it is moved slowly. However, for some distances that are neither too far nor too short, using a trailer is expensive. Therefore, many users still choose to walk to the work site by track. However, the single fixed track roller and the swaying amplitude of the track make it easy to derail. If the tension is too high and the track is too tight, it will be too tight to move when it arrives at the work site. The harsh working environment with a lot of mud and sand, as well as more sealing points and lubrication points, increases the probability of failure. For example, mud and water can enter the bearings, making maintenance difficult and allowing mud and sand to enter easily. A movable rod 9 is slidably connected to the chassis support 1. A roller support 7 is slidably connected to the chassis support 1. The movable rod 9 has a first abutment block 10 that abuts against the roller support 7 and pushes the roller support 7 upwards. The surface of the first abutment block 10 abutting against the roller support 7 is inclined. The chassis support 1 has a drive assembly for driving the track roller 6 and support roller 8 to move. The drive assembly includes a first cylinder 14 mounted on the chassis support 1. A push block 15 connected to the first cylinder 14 is slidably connected to the chassis support 1. The movable rod 9 has a second abutment block 16 that abuts against the push block 15. The abutment surface of the second abutment block 16 abutting against the push block 15 is inclined. When using this product, under normal conditions, only a single track roller 6 contacts and supports the track. When this type of engineering equipment needs to be used, if the distance is relatively short and using a trailer is costly, the switch of the first cylinder 14 can be opened first to allow the cylinder to move. 14. The inflation control piston moves, driving the connected push block 15 to move outward and abut against the abutment block 16 of the moving rod 9. Simultaneously, by adhering to the abutment block 16, the moving rod 9 moves synchronously. When the thrust of the push block 15 is insufficient to overcome the elastic force of the spring 18 at the bottom of the abutment block 16, but the thrust of the push block 15 is greater than the weight of the moving block and all the objects on the roller seat 7, the abutment block 16 cannot be pushed down. At the same time, the moving rod 9 is driven so that the abutment block 10 pushes the roller seat 7 and the track roller 6 upward along the inclined surface at the bottom of the roller seat 7. This causes the track roller 6 to support the track assembly 2 upward. At the same time, it can also work with the guide wheel 4 to synchronously start and adjust the track tension. If it is sufficient, only the track roller 6 needs to be adjusted. This depends on the actual situation. Therefore, there is no need to adjust the guide wheel 4 to avoid the difficulty of adjustment due to the large size of the guide wheel 4.

[0030] The chassis support 1 has several support wheels 8 on both sides of the support wheel 6. The chassis support 1 has a fixing member 11 that is rotatably connected to the support wheel 8. The fixing member 11 is slidably connected to the chassis support 1. The moving rod 9 is slidably connected to the sleeve 12. Two connecting rods 13 are rotatably connected to both sides of the sleeve 12. The end of the connecting rod 13 away from the sleeve 12 is rotatably connected to the fixing member 11. The chassis support 1 has a switching push block 15 that is connected to the moving rod 9 and the sleeve 12 as an adjustment component. The adjustment assembly includes a blocking block 17 mounted on the chassis support 1. The blocking block 17 is located at the roller seat 7 and abuts against the first abutment block 10, preventing the abutment block 10 and the moving rod 9 from moving further. The sleeve 12 is staggered with the moving rod 9, and the moving rod 9 first abuts against the push block 15. A spring 18 is provided between the second abutment block 16 and the moving rod 9 to support the second abutment block 16, and the elastic force of the spring 18 is less than the interaction force between the first abutment block 10 and the cylinder 14. The bottoms of the push block 15, the sleeve 12, and the moving rod 9 are all in contact with the chassis support 1, and the push block 15 is also in a state of being sleeved outside the moving rod 9. After the above operations, the height of the track roller 6 is adjusted, and the track assembly 2 is better supported. At the same time, the cylinder 14 continues to push outward. When the abutment block 10 continues to move and abuts against the blocking block 17, the continuous thrust and the mutual force between the blocking block 17 and the cylinder 14 will create a component force. By blocking the force generated by the cylinder 14, the force generated by the blocking block 17 can overcome the elastic force of the spring 18 and push the abutment block 16 downward along the inclined surface. At this time, the pushing block 15 can pass over the moving rod 9 and continue to move forward, directly abutting against the sleeve 12 that is misaligned with the moving rod 9. As it continues to move, it can drive the sleeve 12 to move, which in turn drives the connecting rod 13 to move. Since the two ends of the connecting rod 13 are respectively connected to the sleeve... The tube 12 and the fixing member 11 are rotatably connected. When the tube 12 is pushed, the connecting rod 13 will rotate along the tube 12. Because the fixing member 11 is restricted by the guide groove 21, the fixing member 11 can only move to the side when the connecting rod 13 is pushed, and the support wheel 8 moves synchronously to fit with the track, thereby achieving the effect of supporting the track assembly 2. At the same time, the track is supported by the track roller 6 in the middle. The track on both sides of the track roller 6 will be in an inclined state. After the support wheel 8 moves laterally, it can directly contact the track to achieve the effect of support and reduce its swing amplitude. The connecting rod 13 connected here will rotate. Through the interaction and linkage of the blocking block 17, the abutment block 16 and the spring 18, the connection between the push block 15 and the moving rod 9 and the tube 12 can be switched.

[0031] Several support wheels 8 are connected by connectors 20. The chassis bracket 1 is provided with guide grooves 21 for guiding the movement of the bottom fixing parts 11 of the support wheels 8. The guide grooves 21 at the bottom of the support wheels 8 are staggered. The guide grooves 21 are provided with abutting blocks 22 that abut against the fixing parts 11 and push the fixing parts 11 and the support wheels 8 upward. The number of abutting blocks 22 and guide grooves 21 corresponds to the number of support wheels 8. A spring 19 is provided between the sleeve 12 and the chassis bracket 1. Finally, after the fixing member 11 moves along the guide groove 21, it drives the support wheel 8 to move synchronously. After moving to the end of the guide groove 21, the fixing member 11 will directly abut against the third abutment block 22 and move up along the inclined surface of the third abutment block 22. At the same time, the third abutment block 22 is consistent, but the height of the support wheel 8 is different and deviates. The closer to the side, the lower it is. This raises the support wheel 8 so that the support wheel 8 also supports the upper part of the track assembly 2. After supporting the track, the adjacent support wheels 8 also maintain a height difference. This achieves the effect of jointly supporting the track assembly 2, distributing the load-bearing pressure of the upper section of the track assembly 2, and the multiple support points greatly reduce the sway of the upper and lower sections of the track. The movement amplitude is reduced, thus lowering the risk of vibration and derailment caused by track swaying during high-speed travel. The number of support wheels 8 can be adjusted as needed. With multiple support wheels 8, the fixing parts 11 on different support wheels 8 are staggered to avoid mutual obstruction. At the same time, the guide grooves 21 of the fixing parts 11 at different positions are also staggered to avoid overlapping during movement. This ensures that the track can be smoothly pushed upward by the abutment block 3 22. Because the track is located on the side of the track roller 6, it will tilt and become closer to the chassis bracket 1. At the same time, the support wheels 8 closer to the sides are set lower, which can better fit the track without excessive tension. Conversely, when resetting is required, air is released through cylinder 14, and the internal spring pushes cylinder 14 to reset. Simultaneously, the push block 15 separates from the sleeve 12. The push block 15, now disengaged from the sleeve 12, pushes the spring 19, which in turn pushes the sleeve 12 back to its original position. This causes the sleeve 12 to pull the connecting rod 13 and the fixing member 11 back to their original positions, thus controlling the support wheel 8 to reset along the guide groove 21. With this device, when traveling on a flat road, the positions of the track roller 6 and the support wheel 8 can be adjusted to support and tighten the track assembly 2, distributing the tension in the upper section of the track. The multiple support points significantly reduce the swaying amplitude of the track sections, lowering lateral vibration and derailment risk during high-speed travel. This allows for faster movement and easier access to the work site. Conversely, once at the work site, where there is a lot of mud, sand, and gravel, and the environment is harsh, the reset support rollers 8 and track rollers 6 allow the track to have some slack. This improves maneuverability during slow movement and allows for slow climbing on different terrains. The swaying also provides sufficient space for mud and sand to dissipate without excessive jamming, and facilitates troubleshooting. Compared to existing technologies, this design is more adaptable and better suited to different operating environments. Its simple structure allows for quick adjustments and better practical application.

[0032] The chassis support 1 has protrusions 23 on both sides of the moving rod 9 that abut against the pushing block 15. The protrusions 23 are slidably connected to the chassis support 1. A rotating rod 24 is rotatably connected to the bottom of the protrusions 23. The middle of the rotating rod 24 is rotatably connected to the chassis support 1. A limiting block 25 is rotatably connected to the other end of the rotating rod 24, which abuts against the moving rod 9 and prevents the moving rod 9 from moving backward. A spring 26 is provided at the bottom of the rotating rod 24 on one side of the protrusion 23. The protrusion 23 is ball-shaped. By pushing block 15 to move past the abutment block 16 on the moving rod 9, push block 15 will abut against protrusion 23 on chassis bracket 1, and press protrusion 23 downward, causing protrusion 23 to move down and compress spring 26. At the same time, the downward-moving protrusion 23 will drive the lower rotating rod 24 to move down. Since the rotating rod 24 is rotatably connected to chassis bracket 1 along the middle, when the rotating rod 24 at one end of protrusion 23 moves down, it will drive the rotating rod 24 at the other end to move up, and drive the connected limiting block 25 to move up, pass through chassis bracket 1, and abut against moving rod 9, thus preventing moving rod 9 from moving backward. After the moving block 15 moves to the protrusion 23, it abuts against the protrusion 23 and restricts the protrusion 23 to be pushed upward by the spring 3 26. As a result, the limiting block 25 cannot move downward, which can ensure that the blocking moving block will not be pushed backward by the spring 4 32. Thus, when the pushing block 15 continues to move forward and comes into contact with the sleeve 12 and cancels the obstruction of the second abutment block 16, the position of the moving rod 9 is fixed and it is sufficient to support the roller seat 7. This ensures that the abutment block 10 will not move backward due to the weight of the roller seat 7 and the roller 6 during operation. In addition, the ball-shaped protrusion 23 makes it convenient for the pushing block 15 to squeeze the protrusion 23 downward when it moves.

[0033] The chassis bracket 1 is provided with a detachable limiting member 28 at the blocking block 17, and the blocking block 17 is engaged with the limiting member 28. The moving rod 9 is provided with a fourth abutment block 29 at the rear end of the first abutment block 10, which is consistent with the first abutment block 10. The guide groove 21 has a convex cross section, and the end of the guide groove 21 is provided with a slot 27 at the rear end of the third abutment block 22 to accommodate the moving and passing-through of the fixing member 11. Secondly, when multiple support wheels 8 and the intermediate support roller 6 need to be disassembled, the screws of the upper limit member 28 at the blocking block 17 of the chassis bracket 1 are removed. Then, the limit member 28 is slid outward and pulled out. Because the limit member 28 is engaged with the blocking block 17, the blocking block 17 is also disassembled. In this state, the cylinder 14 is driven to continue pushing the moving rod 9 to the support roller seat 7. Since it is no longer blocked by the blocking block 17, there will be no mutual force. At the same time, the moving rod 9 is continued to be pushed, and the abutment block 16 will not be pushed downward. Thus, the abutment block 10 can push the support roller completely. The seat 7 continues to move forward, causing the abutment block 4 29 to continue to abut against the roller seat 7, and continuously pushing the roller seat 7 to rise. At the same time, the kit can still be pushed because the kit and the push rod are fitted outside the moving rod 9. Thus, the movement of the kit drives the connecting rod 13 to push the fixing part 11. When the fixing part 11 abuts against the abutment block 3 22, it continues to move, causing the fixing part 11 to move backward along the abutment block 3 22 to the slot 27, thereby breaking away from the restriction of the guide slot 21. After this state, the track assembly 2 can be disassembled, and then the track roller 6 and the support roller 8 can be pulled upward in sequence for replacement, which is convenient for disassembly, maintenance and replacement.

[0034] The chassis support 1 is slidably connected to the parts on both sides of the moving rod 9 that abut against the push block 15. The bottom of the support block 30 is provided with a second cylinder 31 that pushes the support block 30 upward. The push block 15 is slidably connected to the piston of the first cylinder 14. A fourth spring 32 is provided between the moving rod 9 and the chassis support 1. Meanwhile, cylinder 2 31 and rotating rod 24 are misaligned. During use, if it is not necessary to move the track roller 6 upward, and only the support roller 8 needs to be added to abut against the track assembly 2, cylinder 2 31 can be controlled to drive the support block 30 upward, and the slidingly connected push block 15 will be driven upward simultaneously. This raises the support block 30, and the push block 15 also rises and is misaligned with the protrusion 23 and the abutment block 2 16. Thus, when cylinder 1 14 is activated to continue pushing, the push block 15 will move directly over the abutment block 2 16 and the protrusion 23, and will not drive the moving rod 9 to move. At the same time, the push block 15 slides with the piston of cylinder 1 14 when it moves upward, thus ensuring that it will not separate even when it moves upward. Through the above settings, the height of the support roller 8 can be adjusted independently and it can fit against the track. The degree of track support can be adjusted according to the actual usage, terrain and environmental adaptability.
