Description

Technical Field

[0001] This invention relates to a protective device for a tracked walking mechanism and a bucket wheel reclaimer, belonging to the field of mechanical engineering technology. Background Technology

[0002] Bucket wheel stacker-reclaimers, as a continuous and efficient bulk material loading and unloading conveying machine, have been widely used in ports, power plants, steel mills, mines, and other industries. A bucket wheel stacker-reclaimer is also simply called a reclaimer. It is a track-mounted bulk material handling equipment developed from a small bucket wheel excavator, primarily used for the stockpiling and excavation of bulk materials.

[0003] Currently, the integration of tracked discs with the material reclaimer significantly improves the reclaimer's mobility, but also presents serious challenges for tracked chassis in complex terrain conditions. The key component of a tracked chassis is the track drive system, which includes track pads, drive sprockets, track rollers, guide rollers, and a travel reducer. As the track drive system is exposed, large particles can easily enter and cause failures in its components, primarily through wear, deformation, and breakage. The components themselves are costly and difficult to replace; failures result in substantial cost losses and severely impact the overall machine's performance.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a protective device for a tracked walking mechanism and a bucket wheel reclaimer. The first and second protective components provide double protection for the track assembly during the material reclaiming process, ensuring that the meshing mechanism and other operating components of the track assembly are not damaged during material reclaiming, thereby improving the service life of the track assembly and thus improving the working efficiency of the reclaimer.

[0006] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0007] In a first aspect, the present invention provides a protective device for a tracked walking mechanism, comprising:

[0008] The first protective component is detachably connected to the turntable above the two track sets, and the shielding surface formed by the first protective component at least shields the empty space between the two track sets.

[0009] The second protective component includes a fan-shaped baffle plate. A first connecting portion extends outward from the apex of the fan-shaped baffle plate, and a second connecting portion extends outward from the starting corner. Any two adjacent track pins of the track assembly are rotatably connected to the fan-shaped baffle plate via the first and second connecting portions, respectively. The fan-shaped baffle plates arranged in the same row on the track assembly have the same direction, and two adjacent fan-shaped baffle plates form an overlapping surface. Multiple rows of fan-shaped baffle plates are arranged on the track pins of the same track assembly, and two adjacent rows of the second protective components have opposite directions. In this manner, multiple rows of the second protective components are arranged on the track assembly to protect the meshing mechanism in the track assembly.

[0010] Furthermore, the first protective component includes a fan-shaped protective plate and an annular fixing component; the annular fixing component is sleeved on the outer periphery of the turntable; multiple fan-shaped protective plates are stacked from top to bottom, and one end is rotatably connected to the annular groove of the annular fixing component; a limit block is provided between two adjacent fan-shaped protective plates, and when the fan-shaped protective plate rotates along the annular groove to form a circular shielding surface or retracts into an overlapping state, each of the limit blocks cooperates to limit the movement.

[0011] Furthermore, the fan-shaped protective plate includes a first protective plate, a second protective plate, and a third protective plate; the upper and lower surfaces of the first, second, and third protective plates are respectively provided with an upper limit stop and a lower limit stop, and a T-shaped limit block is provided at one end near the center.

[0012] The first, second, and third protective plates are stacked from top to bottom, with the end equipped with the T-shaped limiting block staggered in the annular slot. The upper limit block of the second protective plate engages with the lower limit block of the first protective plate, and the lower limit block of the second protective plate engages with the upper limit block of the third protective plate. Two of the fan-shaped protective plates are installed in the annular slot.

[0013] Furthermore, pads are provided on both sides of the first connecting part and the second connecting part to prevent two adjacent second protective members in multiple rows from contacting and rubbing against each other.

[0014] Furthermore, the first connecting part and the second connecting part are provided with a first pin hole for the track pin to be inserted to form a rotatable connection.

[0015] Furthermore, the pad is an annular block; an annular block is provided on each side of the first pin hole.

[0016] Furthermore, it also includes a concave cleaning brush; the concave cleaning brush is provided between any two adjacent heavy wheels in the track assembly; the bristles of the concave cleaning brush are arranged to contact the track teeth at the upper concave part, and the bristles of the non-concave part are arranged to contact the track plate.

[0017] Secondly, the present invention provides a bucket wheel reclaimer that employs any of the tracked walking mechanism protection devices described above.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0019] 1. The first protective component provided by this invention shields the area between the two sets of actuators, preventing larger particles falling from above from entering the area between the two sets of actuators and subsequently falling into the walking device system, causing damage to internal components. Falling materials are collected on the first protective component, preventing them from falling onto the work site and affecting the tracked walking mechanism.

[0020] 2. The second protective component provided by this invention is installed on each track plate (track pins on both sides of the track plate). When the tracked traveling mechanism is running on flat or uneven terrain, the second protective component can prevent material on the ground from entering the meshing mechanism inside the tracked traveling mechanism. When several track plates are in an uneven state, the corresponding rows of second protective components can overlap each other to prevent larger particles from entering. When the slope of the concave or convex surface is large, the multiple rows of second protective components can provide layer-by-layer protection to prevent larger particles from entering the meshing mechanism.

[0021] 3. The cleaning brush provided by this invention is designed to work in conjunction with the track plate and track teeth to remove small particles of material, thereby preventing repeated wear of small particles from damaging the running track teeth and support rollers / drive wheels.

[0044] Combination Figure 7 and Figure 8The tracked running gear is a key component for supporting and moving heavy machinery, and its structural connection method is crucial to the performance and stability of the entire mechanism. A tracked running gear typically consists of guide wheels, a tensioning device, a track frame, track rollers 8, a drive unit, track carrier rollers, and track shoes 5. Guide wheels are located at both ends of the track and guide its correct direction, ensuring it doesn't derail. The tensioning device adjusts the track tension, preventing it from becoming too tight or too loose during operation. The track frame, as the supporting structure of the tracked running gear, bears the weight of the entire machine. Track rollers 8, also called road rollers, support the weight of the machinery and roll under the track, reducing direct friction between the track and the ground. The drive unit includes track rollers 8 and a motor; the motor provides power, and the track rollers 8 engage with the track, propelling it forward. Track carrier rollers are located inside the track, assisting in supporting the track and reducing track sagging. Track shoes 5 are the main body of the track, usually made of metal or rubber, and are connected by track pins 6.

[0045] The connection of track plates 5 typically involves the cooperation of track pins 6 and track plates 5. Track plates 5 have holes at both ends, and track pins 6 connect the individual track plates 5 to form a continuous track chain. Track teeth 7 are provided on the track plates 5, which mesh with the teeth on the outer circumference of the support rollers 8 and drive wheels 9 during operation, thereby straightening the tracks and preventing them from slipping off during turning or side-slipping. Figure 7 The existing protective plate design and installation, specifically installed above the support rollers, has poor protective effect and cannot be adapted to various terrains.

[0046] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0047] Example 1:

[0048] See Figures 1 to 18 This embodiment provides a protective device for a tracked walking mechanism, including a first protective component 1 and a second protective component 2. The first protective component 1 is detachably mounted on a turntable, and the second protective component 2 is mounted on the track plate 5. The first protective component 1 prevents material from falling from above into the component between the two track sets 4. The first protective component 1 collects the falling material, solving the problem at its source and preventing material from falling to the ground and being carried back into the drive mechanism when the tracked walking mechanism is moving. The shielding surface formed by the first protective component 1 at least covers the empty area between the two track sets, preventing material from falling into the area between the two track sets.

[0049] The two parts of the second protective component 2 are respectively rotatably connected to any two adjacent track pins 6 of the track assembly 4, and an overlapping surface is formed between adjacent second protective components 2 after installation. According to this installation method, multiple rows of second protective components 2 are provided on the track chain of each track assembly 4. These multiple rows of second protective components 2 prevent larger particles of material from entering the meshing mechanism within the track assembly 4. The purpose of forming an overlapping surface is to ensure that when the track plate 5 encounters uneven terrain, the corresponding adjacent second protective components 2 will cross or rotate outwards relative to each other. When rotating outwards, the overlap between the two second protective components 2 decreases, but it still prevents material from entering. This compensates for the problem of material entering through gaps in the existing protective plates due to uneven terrain.

[0050] The inner and outer sides of the rotatable connection between the second protective component 2 and the track pin 6 are respectively provided with pads 22. The purpose is to prevent the second protective components 2 arranged in the same row from interfering with each other or to prevent the second protective components 2 in two adjacent rows from interfering with each other, thereby improving the service life of the second protective component 2 and avoiding friction between the second protective components 2 from causing resistance to track movement.

[0051] Specifically, in combination Figures 7 to 16 As shown, in some embodiments, the second protective member 2 includes a fan-shaped baffle 23. A first connecting portion 24 extends outward from the apex of the fan-shaped baffle 23, and a second connecting portion 25 extends outward from the starting corner of the fan-shaped baffle 23. Both the first connecting portion 24 and the second connecting portion 25 have pin holes. The extended first connecting portion 24 and the second connecting portion 25 can better connect with the track pins 6 on both sides of the track plate 5, facilitating contact connection with the track plate 5.

[0052] like Figure 9 and Figure 11 Multiple track plates 5 on the track assembly 4 are connected in pairs by track pins 6. Any two adjacent track pins 6 on the track assembly 4 are rotatably connected to pin holes provided on the first connecting part 24 and the second connecting part 25 of a fan-shaped baffle plate 23, respectively. Meanwhile, the fan-shaped baffle plates 23 arranged in the same row on the track assembly 4 according to this installation method are oriented in the same direction, and two adjacent fan-shaped baffle plates 23 overlap each other. This arrangement is as follows: Figure 12 Multiple rows of fan-shaped baffles 23 are mounted on the track pins 6 of the same track group 4, and the directions of two adjacent rows of fan-shaped baffles 23 are opposite. At some uneven intersections, if gaps appear between the same-direction fan-shaped baffles 23 in the same row, the adjacent fan-shaped baffles 23 in opposite directions can fill the gaps between the same-direction fan-shaped baffles 23 and continue to prevent material from entering the meshing mechanism (the meshing mechanism includes the meshing of track teeth 7 and support rollers 8, or the meshing of track teeth 7 and drive wheels 9).

[0053] In some implementations, such as Figures 1 to 6 As shown, the first protective component 1 includes a fan-shaped protective plate 11 and an annular fixing component 12. The annular fixing component 12 is detachably fitted onto the outer circumference of the turntable. Multiple fan-shaped protective plates 11 are stacked sequentially from top to bottom, and one end of each fan-shaped protective plate 11 is rotatably connected to the annular groove 13 of the annular fixing component 12. Limiting blocks are provided between two adjacent fan-shaped protective plates 11. When the fan-shaped protective plates 11 are rotated in the forward direction along the annular groove 13, the fan-shaped protective plates 11 rotate relative to each other until the limiting blocks mutually restrict each other, and the multiple fan-shaped protective plates 11 form a circular shielding surface. When the fan-shaped protective plates 11 are rotated in the reverse direction, causing the fan-shaped protective plates 11 to rotate to the mutually restricting state, the fan-shaped protective plates 11 retract to an overlapping state. The stacking of multiple fan-shaped protective components facilitates the operator's maintenance of the components between the track assembly 4. Furthermore, it facilitates production, storage, and refrigeration, reducing the space occupied.

[0054] Specifically in some embodiments, such as Figure 2 , Figure 3 and Figure 4 Six sector-shaped protective plates 11 are installed on the annular rotating component. Three sector-shaped protective plates 11 are arranged as a group, including a first protective plate 14, a second protective plate 15, and a third protective plate 16. Upper limit blocks 17 and lower limit blocks 18 are respectively provided on the upper and lower surfaces of the first protective plate 14, the second protective plate 15, and the third protective plate 16. That is, upper limit blocks 17 are provided on both sides of the upper surface of the first protective plate 14, and lower limit blocks 18 are provided on both sides of the lower surface. The second protective plate 15 and the third protective plate 16 are similarly arranged. A T-shaped limiting block 19 is provided at one end of the first protective plate 14, the second protective plate 15, and the third protective plate 16 near the center. This T-shaped limiting block 19 is configured to cooperate with the annular groove 13. Figure 6 In use, the six fan-shaped protective plates 11 restrict each other, but can rotate 360° around the annular slot 13. This allows for flexible selection of the exposed area after folding.

[0055] like Figure 5 Two sets of first protective plates 14, second protective plates 15, and third protective plates 16 are stacked from top to bottom, with one end of the T-shaped limiting block 19 staggered in the annular slot 13. The upper limit block at the front of the second protective plate 15 engages with the lower limit block at the rear of the first protective plate 14, and the lower limit block at the rear of the second protective plate 15 engages with the upper limit block at the front of the third protective plate 16. This state is an unfolded circular shielding surface. Similarly, when the upper limit block at the front of the second protective plate 15 engages with the lower limit block at the front of the first protective plate 14, and the lower limit block at the rear of the second protective plate 15 engages with the upper limit block at the rear of the third protective plate 16, the plate is in a retracted stacked state.

[0056] Optionally, a first pin hole 26 is provided on the first connecting portion 24 and the second connecting portion 25 of the fan-shaped baffle 23. The pad 22 is configured as an annular block, respectively disposed on both sides of the inlet and outlet of the first pin hole 22. This arrangement is used to prevent interference between adjacent fan-shaped baffles 23 in multiple rows, so that the fan-shaped baffles 23 can flexibly rotate and cooperate with each other to provide protection according to the uneven terrain.

[0057] In some embodiments, the track walking mechanism protective device further includes a concave cleaning brush 3. A concave cleaning brush 3 is installed between any two adjacent heavy wheels 8 in the track assembly 4. Specifically, the bristles 32 of the upper concave portion 31 of the concave cleaning brush 3 are in contact with the track teeth 7, ensuring that the bristles 32 remove small particles from the track teeth 7. The bristles 32 of the non-upper concave portion 31 of the concave cleaning brush 3 are in contact with the track plate 5, removing small particles from the track plate 5 except for the track teeth 7.

[0058] By using the above embodiments and the concave cleaning brush 3, the meshing mechanism of the tracked walking mechanism can be kept clean and hygienic when operating on complex terrain. This effectively prevents large particles from entering the transmission system due to the track drive device being exposed. The triple protection of the first protective component 1, the second protective component 2, and the concave cleaning brush 3 prevents materials from entering the meshing mechanism and other operating mechanisms, thus avoiding wear, deformation, and breakage. This improves the service life of the tracked walking mechanism, reduces maintenance frequency, and enhances work efficiency.
