Description

Technical Field

[0001] This utility model relates to the field of chain anti-derailment technology, and in particular to an anti-derailment device and a tracked chassis. Background Technology

[0002] The working environment of amphibious water pumps is unique in daily operation. Factors such as the unevenness of the salt pan floor and the differential steering system cause excessive tension on the track links during operation. This overload tension, acting continuously on the links, keeps them under tension, leading to plastic deformation. The accumulation of this plastic deformation causes the tracks to loosen, severely impacting the normal operation of the water pump.

[0003] When a water-extracting machine is performing harvesting operations, if the tracks become loose, especially if the looseness is concentrated in the upper part of the track support, the track links can easily slip off from both sides of the track rollers, eventually causing the tracks to derail. Track derailment not only affects the operating efficiency of the water-extracting machine but can also damage the equipment, increasing maintenance costs and downtime.

[0004] Previously, the tension adjustment of amphibious water pumping machine tracks relied primarily on the operator's experience. This experience-based method has several drawbacks. Firstly, the varying experience levels of different operators make it difficult to achieve a uniform standard for track tension. In complex operating environments, this uncertainty acts as a potential hazard, significantly increasing the risk of track derailment. Secondly, the lack of a scientific and precise tension adjustment method prevents the water pumping machine from adjusting track tension promptly and effectively under different working conditions, thus compromising the stable operation of the equipment.

[0005] In summary, the existing track tensioning methods for amphibious water pumps have obvious defects, and there is an urgent need for a technical solution that can effectively solve the track derailment problem. Utility Model Content

By using the first channel between the baffles to limit the lateral position of the track links, the track links are ensured to always run along the predetermined position, preventing the track from derailing and effectively solving the problem of track derailment.

[0007] To achieve the above objectives, this utility model provides the following solution:

[0008] This utility model provides an anti-derailment device, including a base and two baffles. The base is used to install on a fixed frame, and the fixed frame is used to install a track. The track includes a chain plate and chain links connected to the inner side of the chain plate. The two baffles are installed on the base with a gap between the top of the baffle and the chain plate, and a first channel is formed between the two baffles for the chain links to pass through. The width of the first channel is greater than the width of the chain links. Each baffle includes a straight plate portion and an inclined plate portion. Both the straight plate portion and the inclined plate portion are vertically installed on the base. The two ends of the straight plate portion are respectively connected to the inclined plate portion. The straight plate portions of the two baffles are parallel to each other, and the inclined plate portions at the same end of the two baffles are distributed in a V-shape.

[0009] In one embodiment, a first reinforcing plate is further included, which is connected to the side of the straight plate portion away from the first channel, and the bottom of the first reinforcing plate is connected to the base.

[0010] In one embodiment, the base includes a base plate, a support plate, and a seat plate. The top surface of the support plate is connected to the seat plate, and the bottom surface of the support plate is connected to the base plate. The base plate is used to connect to the fixing frame, and the seat plate is used to install the baffle.

[0011] In one embodiment, at least two support plates are provided, and the different support plates are parallel to each other.

[0012] This utility model provides a tracked chassis, including a fixed frame, tracks, and an anti-derailment device as described above. The tracks are arranged around the fixed frame, the anti-derailment device is installed on the fixed frame, and the chain links can run through the first channel.

[0013] In one embodiment, the device further includes a drive wheel, a guide wheel, a support wheel, and a chain roller. The drive wheel and the guide wheel are respectively installed at both ends of the length direction of the fixed frame. The support wheel is installed at the bottom of the fixed frame, and the chain roller is installed at the top of the fixed frame. The chain link is engaged with the drive wheel, the guide wheel, the support wheel, and the chain roller. The anti-derailment device is installed in the middle of the length direction of the fixed frame. There are two chain rollers, which are respectively located on both sides of the anti-derailment device.

[0014] In one embodiment, a salt-proof device is also included, which is installed at the bottom of the fixed frame, and the salt-proof device is respectively provided on both sides of the support roller.

[0015] In one embodiment, the salt-proof device includes a guide plate, a mounting plate, and a salt-proof plate. The mounting plate is used to install on the fixed frame.

[0019] This utility model includes a base and a baffle. The base can be installed on a fixed frame, and the baffle can form a first channel on the base. The chain link passes through the first channel. When the track is running normally, because there is a gap between the top of the baffle and the chain plate, and the width of the first channel is greater than the width of the chain link, the baffle will not affect the track operation. When the track tends to derail, the baffle can block and limit the position of the chain link, so that the chain link is limited within the first channel formed by the baffle. Thus, the first channel between the baffles can be used to limit the lateral position of the track chain link, ensuring that the chain link always runs along the predetermined position, preventing the track from derailing, and effectively solving the problem of track derailment. At the same time, the inclined plate is V-shaped, which reduces the wear of the baffle on the chain link. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The purpose of this utility model is to provide an anti-derailment device and a tracked chassis to solve the problems existing in the prior art. By using the first channel between the baffles to limit the lateral position of the track links, the track links are ensured to always run along the predetermined position, preventing the track from derailing and effectively solving the problem of track derailment.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-6As shown, this utility model provides an anti-derailment device, including a base 71 and two baffles 72. The base 71 is used to install on a fixed frame 1, which is used to install a track 2. The fixed frame 1 can support the operation of the track 2. The track 2 includes a chain plate 21 and chain links 22 connected to the inner side of the chain plate 21. The chain links 22 are used to mesh with wheels such as drive wheels 3, so as to support, drive, and tension the track 2 using the drive wheels 3, etc. The chain plate 21 is used to increase the contact area of ​​the track 2 to ensure smooth movement on soft ground. The two baffles 72 are installed on the base 71 with a gap between them. There is a gap between the top of the baffle 72 and the chain plate 21 to avoid frictional wear between the chain plate 21 and the baffle 72 when the track 2 is running. A first channel is formed between the two baffles 72 for the chain links 22 to pass through. The width of the first channel is greater than the width of the chain links 22 to avoid frictional wear between the chain links 22 and the baffles 72 when the track 2 is running. The baffle 72 includes a straight plate portion 721 and an inclined plate portion 722. Both the straight plate portion 721 and the inclined plate portion 722 are vertically mounted on the base 71. The two ends of the straight plate portion 721 are respectively connected to the inclined plate portion 722. The straight plate portions 721 of the two baffles 72 are parallel to each other. The inclined plate portions 722 at the same end of the two baffles 72 are distributed in a V-shape. The angle between the inclined plate portion 722 and the straight plate portion 721 can be set to 30° to 60°, for example, 45°. Thus, at both ends of the baffle 72, that is, at the positions where the chain link 22 enters and exits the first channel, the baffle 72 is open in a V-shape, so as to avoid frictional wear between the chain link 22 and the end of the baffle 72 when the track 2 has a tendency to shake or even derail.

[0037] This utility model includes a base 71 and a baffle 72. The base 71 can be installed on a fixed frame 1. The baffle 72 can form a first channel on the base 71, and the chain link 22 passes through the first channel. When the track 2 is running normally, since there is a gap between the top of the baffle 72 and the chain plate 21 and the width of the first channel is greater than the width of the chain link 22, the baffle 72 will not affect the operation of the track 2. When the track 2 tends to derail, the baffle 72 can block and limit the position of the chain link 22, so that the chain link 22 is limited within the first channel formed by the baffle 72. Thus, the first channel between the baffles 72 can be used to limit the lateral position of the chain link 22 of the track 2, ensuring that the chain link 22 always runs along the predetermined position, preventing the track 2 from derailing, and effectively solving the problem of track 2 derailment. At the same time, the inclined plate portion 722 is V-shaped, which reduces the wear of the baffle 72 on the chain link 22.

[0038] In one implementation, such as Figure 6As shown, it also includes a first reinforcing plate 73, which is connected to the side of the straight plate portion 721 away from the first channel. The bottom of the first reinforcing plate 73 is connected to the base 71. The first reinforcing plate 73 is vertically arranged, and one or more can be provided. When multiple first reinforcing plates 73 are provided, the different first reinforcing plates 73 can be parallel to each other or intersect. By providing the first reinforcing plate 73, the lateral (width direction of the track 2) support capacity of the straight plate portion 721 for the link 22 can be improved. In addition, the inclined plate portion 722 can also support the straight plate portion 721 to a certain extent, further improving the support capacity of the straight plate portion 721.

[0039] In one implementation, such as Figure 6 As shown, the base 71 includes a base plate 711, a support plate 713, and a seat plate 712. The support plate 713 is vertically arranged, with its top surface connected to the seat plate 712 and its bottom surface connected to the base plate 711. In this example, the support plate 713 is perpendicular to both the base plate 711 and the seat plate 712, thus supporting the seat plate 712. The base plate 711 is used to connect to the fixing frame 1, and the seat plate 712 is used to mount the baffle 72.

[0040] In one embodiment, the support plate 713 can be configured as a flat plate, a serpentine plate, or a zigzag plate, etc. Figure 6 As shown in this example, at least two support plates 713 are provided, and the different support plates 713 are parallel to each other. The above method makes the base 71 simple to manufacture and easy to select materials.

[0041] like Figures 1-6 As shown, this utility model provides a tracked chassis, including a fixed frame 1, a track 2, and an anti-derailment device 7 as described above. The track 2 is arranged around the fixed frame 1, with the fixed frame 1 supporting the operation of the track 2. The fixed frame 1 can also be installed on the vehicle body to support the entire tracked vehicle, such as a water sampling vehicle. The anti-derailment device 7 is installed on the fixed frame 1, allowing the chain link 22 to pass through the first channel. By restricting the position of the chain link 22 through the anti-derailment device 7, the derailment of the track 2 can be effectively prevented.

[0042] In one implementation, such as Figures 1-3As shown, the track also includes a drive wheel 3, a guide wheel 4, a support wheel 6, and a track roller 5. The drive wheel 3 and the guide wheel 4 are respectively installed at both ends of the length direction of the fixed frame 1. The drive wheel 3 drives the rotation of the entire track 2, while the guide wheel 4 acts as a driven wheel to achieve the circular movement of the track 2. The support wheel 6 is installed at the bottom of the fixed frame 1, and multiple support wheels 6 can be arranged in the length direction to support and bear the weight of the fixed frame 1. The track roller 5 is installed at the top of the fixed frame 1 and can tension and guide the track 2. The chain link 22 is engaged with the drive wheel 3, the guide wheel 4, the support wheel 6, and the track roller 5. The anti-derailment device 7 is installed in the middle of the length direction of the fixed frame 1, and there are two track rollers 5, which are located on both sides of the anti-derailment device 7. When the track 2 is running normally, the seat plate 712 should preferably not contact the chain link 22 to reduce frictional wear between the seat plate 712 and the chain link 22.

[0043] In one implementation, such as Figures 1-3 As shown, it also includes a salt-proof device 8, which is installed at the bottom of the fixed frame 1. Salt-proof devices 8 are respectively provided on both sides of the support roller 6. By setting the salt-proof device 8, underwater debris such as salt particles are prevented from entering between the support roller 6 and the chain link 22 as much as possible, so as to avoid radial misalignment of the chain link 22.

[0044] In one implementation, such as Figure 4 and Figure 5 As shown, the anti-salt device 8 includes a guide plate 83, a mounting plate 81, and an anti-salt plate 82. The mounting plate 81 is used to install on the fixed frame 1. The mounting plate 81 may be provided with mounting holes and other installation structures to facilitate a detachable connection method, making it convenient for the maintenance and replacement of the anti-salt device 8. The top surface of the anti-salt plate 82 is connected to the mounting plate 81, and the bottom surface of the anti-salt plate 82 is connected to the guide plate 83. A second channel for the chain link 22 to pass through is formed between the anti-salt plates 82 of different anti-salt devices 8. There is a gap between the guide plate 83 and the chain plate 21. Therefore, when the track 2 is running normally, the guide plate 83 does not contact the track 2 to minimize frictional wear on the track 2. At the same time, when the track 2 has a tendency to derail, the anti-salt plate 82 can also be used to prevent the chain link 22 from derailing. The anti-salt device 8 and the anti-derailment device 7 together ensure the smooth operation of the track 2.

[0045] In one implementation, such as Figure 4 and Figure 5As shown, the salt-proof device 8 also includes a second reinforcing plate 84. The top of the second reinforcing plate 84 is connected to the mounting plate 81, and the bottom of the second reinforcing plate 84 is connected to the guide plate 83. The second reinforcing plate 84 can further enhance the connection strength and stability of the guide plate 83, the salt-proof plate 82, and the mounting plate 81. Multiple second reinforcing plates 84 are spaced apart. The salt-proof plate 82 is provided with a U-shaped opening 85 for avoiding the axle of the support roller 6. The mounting plate 81, the second reinforcing plate 84, and part of the guide plate 83 between adjacent U-shaped openings 85 form a rectangle to ensure the stability of the entire salt-proof device 8.

[0046] In one implementation, such as Figure 5 As shown, the salt-proof device 8 also includes a limiting structure 86. The limiting structure 86 is disposed on the side of the salt-proof plate 82 near the chain link 22. The limiting structure 86 is connected to the salt-proof plate 82 and located between the chain link pin and the support roller 6. By using the limiting structure 86, the chain link pin is prevented from directly colliding with the support roller 6 when it bounces, allowing the limiting structure 86 to contact the chain link pin and reducing wear on the chain link 22. The limiting structure 86 can be a whole strip or intermittently arranged blocking blocks, and is detachably connected to the salt-proof plate 82. The limiting structure 86 is replaced every certain period of time, such as every six months, so that the salt-proof device 8 can be reused, reducing the investment cost of the equipment.

[0047] In one embodiment, the thickness of each plate of the salt-proof device 8 can be designed to be 15mm to 25mm, for example, 20mm, to enhance the strength of the salt-proof device 8. The limiting structure 86 can be a strip block with a width of 45mm to 55mm and a thickness of 15mm to 25mm, for example, a strip block with a width of 50mm and a thickness of 20mm.

[0048] When the tracked chassis of this utility model is applied to a water mining machine, the application of the anti-derailment device 7 and the anti-salt device 8 greatly improves the supply capacity of the raw ore harvesting machine in salt lakes, increases the equipment operating rate, significantly reduces the amount of maintenance work, effectively solves the problem of unstable operation, eliminates the risk of derailment during operation, reduces the amount of maintenance work, ensures the continuity and stability of production, and provides reference experience for the stable underwater operation of the tracked chassis in the industry.

[0049] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
