Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection machine equipment technology, specifically to a track cleaning device. Background Technology
[0002] In modern industrial plants, overhead cranes are indispensable core production equipment, shouldering key production responsibilities such as material transportation and equipment hoisting. Their stable and efficient operation is directly related to overall production efficiency and on-site safety, and is an important guarantee for the smooth progress of the production process.
[0003] To ensure the long-term, stable, and reliable operation of the overhead crane, regular maintenance and inspection of the crane tracks are crucial. This series of inspections is comprehensive and detailed, encompassing meticulous visual inspection of the track surface to check for abnormalities such as wear, deformation, or cracks; precise testing of the torque of the track clamping bolts to ensure that the bolts are tightened to the required standard and prevent safety hazards caused by loosening; and a comprehensive inspection of the integrity of the track joint connections to ensure that all parts of the track are tightly and securely connected, guaranteeing the smooth operation of the overhead crane.
[0004] Track maintenance is typically performed using inspection robots. To ensure the robot's proper movement on the track, it's often necessary to clean the track to prevent impurities from hindering the robot's inspection. Currently used track cleaning devices are mounted in front of the robot and equipped with brush heads with bristles. This allows the robot to clean the track first before moving through it. However, because the brush heads in current cleaning devices are relatively stationary relative to the entire device and can only move in a straight line along the track, particles continuously accumulate as the brush bristles clean, hindering the cleaning of the track ahead and affecting the overall cleaning efficiency. Utility Model Content
[0005] The present invention aims to provide a track cleaning device to solve the problem that the existing cleaning devices have poor cleaning effect because the brush head is stationary relative to the whole device when it is working and can only move in a straight line.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a track cleaning device, including a suspension, a drive shaft rotatably mounted on the suspension, an eccentric wheel fixedly mounted on the drive shaft, a sleeve and a rotatably fitted sleeve on the outer edge of the eccentric wheel, and a support arm fixedly connected to the sleeve.
[0007] The suspension is also equipped with a cantilever, one end of which is equipped with a brush head with bristles, and the brush head is set perpendicular to the cantilever; the other end of the cantilever is fixedly connected to a connecting plate, and a short shaft is fixedly connected to the connecting plate. The short shaft and the cantilever are respectively connected to the two ends of the connecting plate, and the axis of the short shaft is parallel to and offset from the axis of the cantilever.
[0008] The end of the support arm away from the sleeve is provided with a limiting hole, and the short shaft passes through the limiting hole. There is a gap between the outer surface of the short shaft and the wall of the limiting hole.
[0009] The principle and advantages of this solution are as follows: The cleaning device in this solution is installed at the front of the robot and moves with the robot to clean the track. During operation, an external power source drives the drive shaft to rotate. The eccentric wheel on the drive shaft follows the movement, which in turn pushes the support arm up and down via a clamp. The support arm pushes the short shaft, causing it to swing up and down. The short shaft, through a connecting plate, pulls the cantilever arm to swing back and forth, causing the brush head to swing left and right, thus dynamically cleaning the track. Because the brush head performs dynamic cleaning by swinging left and right, impurities on the track surface are directly swept off the track instead of accumulating forward, enhancing the cleaning effect. Furthermore, this dynamic cleaning method of swinging left and right prevents impurities from accumulating on the brush head bristles, keeping the brush head relatively clean for the next cleaning cycle and improving the cleaning effect of each cleaning session.
[0010] Preferably, as an improvement, a limiting groove is provided on the outer edge of the eccentric wheel, and the sleeve includes a first semicircular sleeve and a second semicircular sleeve, which are detachably and fixedly connected, and the inner walls of the first semicircular sleeve and the second semicircular sleeve are provided with a locking protrusion that can engage with the limiting groove.
[0011] The above-described design, with its engaging groove and locking protrusion, ensures that the eccentric wheel and the sleeve are on the same plane. This facilitates the eccentric wheel's pushing action against the sleeve, ensuring effective power transmission. The sleeve employs a detachable and fixed connection between the first and second semicircular sleeves, further simplifying the connection and assembly of the sleeve and the eccentric wheel.
[0012] Preferably, as an improvement, the brush head includes a front brush and a rear brush. The front brush is located on the front side of the cantilever, and the rear brush is located on the rear side of the cantilever. The bristles are disposed on the front brush, and the interior of the rear brush is provided with a cavity that is connected to a negative pressure fan. The bottom of the rear brush is provided with multiple air holes that connect the cavity to the outside of the rear brush.
[0013] With the above scheme, the front brush is used to perform the initial cleaning of the track by swinging back and forth from left to right, and the rear brush is used to perform the secondary cleaning of the track after the front brush has completed the cleaning. When the rear brush moves, it follows the front brush to swing back and forth from left to right, thereby sucking away the impurity particles remaining on the track surface or impurity particles that have fallen back onto the track by negative pressure. This can further enhance the cleaning effect of the track and facilitate the smooth passage and operation of the robot.
[0014] Preferably, as an improvement, it also includes a collection box located below the brush head. The brush head has collection grooves on both sides, and the collection grooves are connected to the collection box. One end of the collection groove has a groove edge, and the other end has an opening located directly above the collection box.
[0015] With the above solution, during operation, the collection box is located below the track. The collection box collects impurity particles swept off by the front brush, preventing them from falling directly onto operators or the equipment structure and thus affecting operation. After the front brush swings left and right, sweeping impurity particles off the track, they fall into the collection troughs on both sides and then into the collection box for storage. Because the collection box is located below the track, it is separated from the rear brush by the track, effectively preventing negative pressure from causing impurity particles to escape from the collection box. This achieves effective collection of impurity particles while preventing swept-off particles from falling back onto the track and affecting the cleaning effect.
[0016] Preferably, as an improvement, the bottom wall of the collection tank slopes downward, with the lower end of the bottom wall of the collection tank located directly above the collection box.
[0017] Through the above method, the impurity particles swept off by the front brush fall into the collection tank and fall into the collection box along the inclined bottom wall of the collection tank for collection, so as to facilitate the collection of impurity particles.
[0018] Preferably, as an improvement, the collection trough is rotatably connected to the collection box.
[0019] The above solution allows for the easy discharge of impurities from the collection box by rotating the collection trough, making it easier to clean the collection box. Attached Figure Description

[0027] Example 1
[0028] Track 21 cleaning device, such as Figure 1 As shown, it includes suspension 1 ( Figure 1 (A partial structure of suspension 1 is shown). A drive shaft 2 is rotatably mounted on suspension 1. An eccentric wheel 3 is fixed on drive shaft 2. A collar is fitted around the outer edge of the eccentric wheel 3 and rotatably engages with it. Figure 2 The eccentric wheel 3 shown has a limiting groove 12 on its outer edge. The sleeve includes a first semicircular sleeve 4 and a second semicircular sleeve 5. The first semicircular sleeve 4 and the second semicircular sleeve 5 are detachably fixed together by bolts, and as shown... Figure 3 As shown, the inner walls of the first semicircular sleeve 4 and the second semicircular sleeve 5 are provided with a snap-fit protrusion 6 that can engage with the limiting groove 12.
[0029] like Figure 1 A support arm 7 is fixedly connected to the sleeve. In this embodiment, the support arm 7 is connected to the second semi-circular sleeve 5. A cantilever arm 8 is also rotatably mounted on the suspension 1. The cantilever arm 8 is longitudinally arranged, and a brush head 9 is provided at its lower end. The brush head 9 has bristles. In this embodiment, the brush head 9 includes a front brush 13 and a rear brush 14, combined with… Figure 4 As shown, the front brush 13 is located on the front side of the cantilever 8, and the rear brush 14 is located on the rear side of the cantilever 8. The bristles are located on the front brush 13. The rear brush 14 has a cavity 15 inside, and the top of the cavity 15 is connected to a negative pressure fan through a connecting pipe. In actual application, the negative pressure fan is fixed on the suspension, so that the negative pressure fan can move with the device. The bottom of the rear brush 14 has multiple air holes 16, which connect the cavity 15 to the outside of the rear brush 14. The brush head 9 is set perpendicular to the cantilever 8. A connecting plate 10 is fixed to the upper end of the cantilever 8, and a short shaft 11 is fixed to the connecting plate 10. The short shaft 11 and the cantilever 8 are respectively connected to the two ends of the connecting plate 10, and the axis of the short shaft 11 is parallel to and offset from the axis of the cantilever 8.
[0030] The end of the support arm 7 away from the sleeve is provided with a limiting hole, and the short shaft 11 is inserted into the limiting hole. There is a gap between the outer surface of the short shaft 11 and the wall of the limiting hole.
[0031] In this embodiment, the drive shaft 2 is connected to a drive source, such as a motor, or a combination of a motor and a reducer. The specific connection method is a mature existing technology and will not be described in detail here. In use, the suspension 1 is fixed in front of the inspection robot base. When the robot walks on the track 21 to perform inspections, this device is driven and walks on the track 21.
[0032] During the process, the front brush 13 continuously cleans the surface of the track 21, thereby removing particulate impurities from the track 21. During cleaning, the drive source drives the drive shaft 2 to rotate, and the drive shaft 2 drives the eccentric wheel 3 to rotate. The long diameter end of the eccentric wheel 3 pushes the support arm 7 back and forth, causing the support arm 7 to push the short shaft 11 to rotate and swing at a small angle. The short shaft 11 drives the cantilever 8 to rotate back and forth through the connecting plate 10, causing the brush head 9 to swing back and forth within a certain angle range to dynamically clean the track 21. After the front brush 13 passes, the rear brush 14 sucks the remaining impurity particles on the track 21 into the cavity 15 through the air hole 16 using negative pressure or directly into the configured collection box to ensure the cleaning effect of the track 21.
[0033] Example 2
[0034] This embodiment is based on embodiment 1, such as... Figure 1 , Figure 4 and Figure 5 As shown, the device also includes a collection box 17, which is fixedly connected to the suspension 1 of the device. During operation, the collection box 17 is located below the brush head 9. The brush head 9 has collection grooves 18 on both sides, which are located on either side of the track 21. One end of each collection groove 18 is rotatably connected to the collection box 17. One end of each collection groove 18 has a groove edge 19, and the other end has an opening 20, which is located directly above the collection box 17. The bottom wall of the collection groove 18 slopes downwards, with the lower end of the bottom wall of the collection groove 18 located directly above the collection box 17.
[0035] In this embodiment, based on Embodiment 1, after the brush head 9 sweeps the impurity particles off the track 21, the particles fall into the collection trough 18 and then along the inclined bottom wall of the collection trough 18 into the collection box 17 for collection and storage. After cleaning is completed and the device is removed from the robot, the collection trough 18 can be moved from above the collection box 17 to the outside of the collection trough 18 by rotating it, so that the impurity particles in the collection trough 18 can be poured out.
