Description
Technical Field
[0001] This application relates to the field of sweeper technology, and in particular to a movable wheel track sweeper device. Background Technology
[0002] A bucket wheel stacker-reclaimer (abbreviated as bucket wheel excavator) is a high-efficiency loading and unloading machine used in large dry bulk cargo yards for continuous conveying of materials, capable of both stacking and reclaiming. Bucket wheel excavators have traveling, rotating, pitching, boom belt conveyor, relay belt conveyor, tail car, and bucket wheel reclaiming mechanisms, meeting the requirements of bidirectional transportation to ground belt conveyors and feeding materials to ground belt conveyors.
[0003] Currently, the tail car of the bucket wheel excavator is a lifting type. Figure 1 , 3 As shown), the tail car rises during material stacking and descends during material retrieval. Each tail car's outriggers are equipped with track cleaners at both ends to remove debris from the track surface, keeping the track clean and ensuring the track wheels roll properly and are supported on the track. However, the existing track cleaners are rigidly connected ( Figure 2 As shown, when the tail car is lifted, the tail car outriggers are tilted. Due to the rigid connection, the track cleaner either does not contact the track or bites the track, resulting in the tail car losing its track debris cleaning function. In addition, due to the huge weight of the tail car, it is easy to be damaged, or even structural deformation and breakage, which poses a safety hazard.
[0004] Therefore, a cleaning device is needed to ensure normal cleaning of the track when the tail car outriggers are tilted, remove debris from the track surface, keep the track clean, and ensure that the track wheels roll normally and support the track. Utility Model Content
[0005] To address the aforementioned problems and enable normal cleaning of the track when the tail car outriggers are tilted, thereby removing debris from the track surface, keeping the track clean, and ensuring the normal rolling support of the track wheels on the track, this application provides a movable wheel track cleaner device.
[0006] The present application provides a movable wheel track cleaner device with the following technical solution.
[0007] A movable wheel track cleaner device includes a tail car support leg, the bottom of which is supported on the track by a track wheel, and a base frame, which is connected to the tail car support leg by a connecting mechanism. The base frame is provided with a cleaner for cleaning the track on the front and rear ends of the track wheel, and the base frame is supported on the track by a walking wheel. The connecting mechanism includes a hinge plate, and the underframe and the tail support leg are hinged together by the hinge plate; The sweeper includes a mounting base on a base frame, and a sweeping brush is mounted on the mounting base.
[0008] By adopting the above technical solution, the underframe is hinged to the tail car outriggers via a hinged plate, and the underframe is supported on the track by traveling wheels. This means the underframe can move along with the tail car outriggers on the track. Because it is hinged, regardless of the tilt of the tail car outriggers, the traveling wheels will always remain on the track, preventing the underframe from tilting. Uneven stress on the track, traveling wheels, and underframe, or structural damage due to concentrated stress, will not occur, and structural deformation or breakage will not occur. Sweepers are installed on the underframe at the front and rear ends of the track wheels for cleaning the track. Since the underframe does not tilt, the sweepers can always maintain contact with the track, preventing them from tilting or compressing and damaging the track, thus ensuring track cleaning.
[0009] Optionally, the base frame includes a cross frame and vertical frames disposed at the front and rear ends of the cross frame, wherein one of the vertical frames is hinged to a hinge plate.
[0010] Optionally, the crossbeam includes two parallel, spaced-apart transverse support members, which are bolted to the vertical frame, and the two transverse support members are located on the left and right sides of the track wheel, respectively.
[0011] By adopting the above technical solution, the two transverse support members are set in parallel intervals, and the space of the rail wheel is used for reasonable structural design. The bolt connection method is simple and reliable, and also facilitates assembly and disassembly.
[0012] Optionally, the traveling wheel is rotatably positioned between two lateral supports.
[0013] By adopting the above technical solution, the traveling wheel is also located between the two transverse support members, ensuring that it is on the same track as the rail wheel support. The space layout is made reasonable, and the installation of the traveling wheel is completed using two transverse support members.
[0014] Optionally, two traveling wheels are provided, distributed at the front and rear ends of the track wheel.
[0015] By adopting the above technical solution, two traveling wheels are set up, and they are distributed at both the front and rear ends of the track wheels. This is beneficial to the support and balance of the base frame, ensuring that the base frame at both the front and rear ends of the track wheels can be stably supported on the track. Maximizing the wheel gap between the two traveling wheels helps to improve support stability, making the base frame less prone to tilting, resulting in smoother movement and improved cleaning of the track by the sweeper.
[0016] Optionally, the connecting mechanism includes a hinge seat disposed on the tail support leg, and the two ends of the hinge plate are respectively hinged to the hinge seat and the vertical frame.
[0017] By adopting the above technical solution, the articulated plate is connected to the tail support leg via the articulated seat.
[0018] Optionally, the hinge seat is provided with a first hinge hole, the vertical frame is provided with a second hinge hole, and the two ends of the hinge plate are respectively hinged to the first hinge hole and the second hinge hole by bolts and nuts.
[0019] By adopting the above technical solution, the hinge is achieved by bolts and nuts, which is simple and reliable, and facilitates assembly and disassembly.
[0020] Optionally, the sweeper includes a plurality of mounting bases, which are spaced vertically apart on the side of the vertical frame away from the horizontal frame.
[0021] Optionally, the mounting base has several mounting slots, and the mounting pressure block is tightened on the mounting base with bolts to press the handle of the cleaning brush into the mounting slot, and the brush head of the cleaning brush cleans the track downward.
[0022] By adopting the above technical solution, the cleaning brush is pressed onto the mounting base by tightening the bolts, making the installation simple, reliable, and easy to replace.
[0023] In summary, this application includes at least the following beneficial effects: In this application, the underframe is hinged to the tail carriage outriggers via a hinged plate, and the underframe is supported on the track by traveling wheels. This means the underframe can move along with the tail carriage outriggers as they travel on the track. Because it is hinged, regardless of the tilt of the tail carriage outriggers, the traveling wheels remain on the track, preventing the underframe from tilting. Uneven stress distribution or concentrated stress on the track, traveling wheels, and underframe will not cause structural damage, deformation, or breakage. Cleaners are installed on the underframe at the front and rear ends of the track wheels for cleaning the track. Since the underframe does not tilt, the cleaners remain in contact with the track, preventing them from tilting, squeezing, or damaging the track, thus ensuring proper track cleaning.

[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 following is in conjunction with the appendix Figures 3 to 7 This application will be described in further detail.
[0035] This application discloses a track cleaner device for movable wheels.
[0036] Reference Figures 3 to 7 The tail car of the bucket wheel excavator includes tail car support legs 1, and the bottom of the tail car support legs 1 is supported on the track 3 by rail wheels 2.
[0037] A track sweeper device with movable wheels includes: a base frame, a connecting mechanism, a sweeper, and walking wheels 6.
[0038] The base frame includes a horizontal frame 4 and vertical frames 5 located at the front and rear ends of the horizontal frame 4. The horizontal frame 4 includes two parallel and spaced transverse support members, which can be channel steel. The two ends of the transverse support members are connected to the vertical frames 5 by bolts, and the two transverse support members are located on the left and right sides of the rail wheel 2, respectively. The parallel and spaced transverse support members make reasonable use of the space of the rail wheel 2 for structural design. The bolt connection method is simple and reliable, and also facilitates assembly and disassembly.
[0039] The base frame is supported on the track 3 by the traveling wheels 6. The traveling wheels 6 are rotatably positioned between two transverse support members, ensuring that they are supported on the same track 3 as the track wheels 2. This efficient use of space, achieved by employing two transverse support members, completes the installation of the traveling wheels 6. Two traveling wheels 6 are provided, distributed at both the front and rear ends of the track wheels 2. This arrangement improves the balance of the base frame, ensuring that both ends of the base frame are stably supported on the track 3. Maximizing the wheel spacing between the two traveling wheels 6 enhances stability, prevents the base frame from tilting, and ensures smoother movement, thus improving the sweeper's cleaning of the track 3.
[0040] The connecting mechanism includes a hinge plate 7 and a hinge seat 8.
[0041] The articulation seat 8 is fixedly mounted on the tail support leg 1. The articulation seat 8 has a first hinge hole, and the vertical frame 5 at one end has a second hinge hole. The two ends of the articulation plate 7 are hinged to the first and second hinge holes respectively using bolts and nuts, thus achieving hinge connection between the two ends of the articulation plate 7 and the articulation seat 8 and the vertical frame 5. By adopting the above technical solution, the articulation plate 7 is connected to the tail support leg 1 via the articulation seat 8, and the hinge is achieved using bolts and nuts. The connection method is simple and reliable, and facilitates assembly and disassembly.
[0042] The sweeper includes a mounting base 9 and a sweeping brush 10.
[0043] A mounting base 9 is provided on the side of the vertical frame 5 away from the horizontal frame 4, with three mounting bases 9 spaced vertically. Three horizontally spaced mounting slots are provided on the mounting base 9 for mounting three cleaning brushes 10. A mounting pressure block 11 is tightened onto the mounting base 9 with bolts, pressing the handles of the three cleaning brushes 10 into the mounting slots. The brush heads of the cleaning brushes 10 clean the track 3 downwards. The cleaning brushes 10 are secured to the mounting base 9 by tightening the bolts, making the installation simple, reliable, and easy to replace.
[0044] In this application, the underframe is hinged to the tail support leg 1 via a hinge plate 7, and the underframe is supported on the track 3 via traveling wheels 6. This means the underframe can move along with the tail support leg 1 on the track 3. Because it is hinged, regardless of the tilt of the tail support leg 1, the traveling wheels 6 will always remain on the track 3, preventing the underframe from tilting. Uneven stress on the track 3, traveling wheels 6, and underframe, or structural damage due to concentrated stress, will not occur, and structural deformation or breakage will not occur. Cleaners are installed on the underframe at the front and rear ends of the track wheel 2 for cleaning the track 3. Since the underframe does not tilt, the cleaners can always remain in contact with the track 3, preventing them from tilting or damaging the track 3, thus ensuring proper cleaning of the track 3.
