Description

Technical Field

[0001] This invention relates to the field of cranes, specifically to a crane travel wheel assembly with track cleaning function. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range; it is also called a hoist. The traveling wheels on a crane mainly serve the function of horizontal movement. During operation, they are driven by a motor to make the traveling wheels roll on the track for horizontal movement.

[0003] Due to prolonged operation, a large amount of oil stains will accumulate on the track. To prevent the movement of the traveling wheels from being obstructed, a scraper is usually installed on the traveling wheels to remove the oil stains and clean the track. After scraping, lubricating oil needs to be applied to the track to reduce wear between the track and the traveling wheels. However, the above operations are mostly done manually by workers, which increases the labor intensity of workers and is inefficient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a crane travel wheel assembly with track cleaning function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a crane traveling wheel assembly with track cleaning function, comprising a track frame and traveling wheels mounted on the track frame.

[0008] Preferably, an opening spring is wound around the outside of the guide post, one end of the opening spring is fixed to the lower end of the connecting frame, the other end of the opening spring is fixed to the upper end of the guide seat, and a positioning cap is coaxially embedded at the lower end of the guide post, the positioning cap being fitted to the lower end of the guide seat.

[0009] Preferably, the retractable component includes a connecting shaft installed at the upper front of the travel wheel assembly. The lubricating oil tank is connected to the connecting shaft. A retractable gear is coaxially embedded at the end of the connecting shaft. A retractable toothed plate meshes with the upper part of the retractable gear. The retractable toothed plate is elastically connected to the travel wheel assembly. A guide plate seat is slidably installed on the outer side of the retractable toothed plate. The guide plate seat is fixed to the travel wheel assembly. A fixing post is elastically installed at the upper end of the guide plate seat. A reset wheel is connected to the upper end of the fixing post.

[0010] Preferably, the lower end of the fixing column passes through the upper end of the guide plate seat and is pressed against the retractable toothed plate. The fixing column and the guide plate seat are slidably engaged. A fixing hole is provided on the upper end face of the retractable toothed plate, and the fixing hole is aligned with the fixing column. A retractable top frame is fixedly installed on the front side of the track frame, and the retractable top frame is aligned with the retractable toothed plate. A reset inclined frame is fixedly installed on the rear side of the track frame, and the reset wheel is aligned with the reset inclined frame.

[0011] Preferably, a groove seat is rotatably mounted on the outer surface of the connecting shaft, the lower end of the groove seat is fixed to the traveling wheel assembly, an extension lug extends from the upper edge of the rear end of the lubricating oil tank, the end of the extension lug is embedded in the connecting shaft, a fixing sleeve is slidably mounted on the outer surface of the fixing column, the fixing sleeve is fixed to the guide plate seat, a convex lug is coaxially embedded on the outer surface of the fixing column, the convex lug is slidably mounted inside the fixing sleeve, a compression spring is wound around the outer side of the fixing column, one end of the compression spring is fixed to the inner top surface of the fixing sleeve, and the other end of the compression spring is fixed to the upper end of the convex lug.

[0012] Preferably, a wheel frame is fixedly installed at the upper end of the fixed column, the return wheel is coaxially installed on the outer surface of the wheel frame, a limiting rod is fixedly installed at the rear end of the retractable toothed plate, an L-shaped seat is slidably installed on the outer surface of the limiting rod, the end of the L-shaped seat is fixed to the walking wheel assembly, a rod cap is coaxially embedded at the end of the limiting rod, the rod cap fits against the rear end of the L-shaped seat, a return spring is wound around the outside of the limiting rod, one end of the return spring is fixed to the front end of the L-shaped seat, and the other end of the return spring is fixed to the rear end of the retractable toothed plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When the traveling wheel assembly rolls forward on the track frame, the V-shaped shovel head will scrape off the oil stains on the track frame. At the same time, the lubricating oil in the lubricating oil tank drips from the oil outlet at the bottom onto the track frame after the oil stains have been removed, and is then spread by the brush body, so that the lubricating oil is evenly attached to the track frame. This process does not require manual application by workers, effectively reducing the labor intensity of workers and improving work efficiency.

[0014] 2. When the traveling wheel assembly is about to reach the end of the track frame, the retractable toothed plate will abut against the retractable top frame, keeping the retractable toothed plate stationary. At this time, the traveling wheel assembly continues to move forward. During this process, the retractable gear rolls on the retractable toothed plate to drive the connecting shaft to rotate, thereby causing the lubricating oil tank and V-shaped shovel head to flip over to the top of the traveling wheel assembly. At this time, the fixing column is pushed out by the pressure spring and inserted into the fixing hole on the retractable toothed plate to fix the flipped lubricating oil tank and V-shaped shovel head, so that they are detached from the track frame. This is to prevent the V-shaped shovel head from damaging the lubricating oil layer during the movement of the traveling wheel assembly. At the same time, when the lubricating oil tank flips over to the top of the traveling wheel assembly, its bottom will be in an upward position, so that the lubricating oil inside the lubricating oil tank will no longer be discharged, thus avoiding the phenomenon of continuous discharge of lubricating oil and waste.

[0015] 3. During the rotation of the lubricating oil tank, the top shell wheel will press against the traveling wheel assembly to support the protective tooth plate. Then, the lubricating oil tank continues to rotate upwards towards the traveling wheel assembly. At this time, the protective tooth plate will gradually move under the support of the traveling wheel assembly, thereby driving the protective gear to rotate. This allows the protective shell at the end of the housing shaft to rotate towards the bottom of the lubricating oil tank and engage with the protective plate. The protective shell and protective plate are used to cover the brush body to prevent dust and other contaminants from adhering to the brush body and causing lubricating oil contamination during application.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0019] This invention provides a technical solution: such as Figures 1-9The crane travel wheel assembly shown includes a track frame 1 and a travel wheel assembly 2 mounted on the track frame 1. A retractable part is located at the upper front of the travel wheel assembly 2, and a lubricating oil tank 9 is connected to the end of the retractable part. The lubricating oil tank 9 is used to load lubricating oil; lubricating oil can be added by unscrewing the sealing cap on the top of the lubricating oil tank 9. Two brushes 14 are symmetrically and obliquely mounted at the lower end of the lubricating oil tank 9, with their ends attached to the track frame 1. The brushes 14 are used to evenly apply lubricating oil to the track frame 1. Multiple oil outlet holes are linearly arranged between the two brushes 14 at the lower end of the lubricating oil tank 9, allowing lubricating oil to drip down. A V-shaped scraper head 12 is fixedly mounted at the lower front end of the lubricating oil tank 9, attached to the track frame 1. The V-shaped scraper head 12 can scrape off oil stains from the track frame 1. A guard plate 15 extends from the lower side of the lubricating oil tank 9. On the other side, a housing shaft 20 is provided at the lower part. One end of the housing shaft 20 is connected to a protective shell 11. The protective plate 15 and the protective shell 11 can cover the brush body 14 to prevent dust and other particles from adhering to the brush body 14. The other end of the housing shaft 20 is coaxially embedded with a protective gear 27. A protective toothed plate 13 meshes with the side of the protective gear 27. The cooperation between the protective gear 27 and the protective toothed plate 13 allows the protective shell 11 to flip towards the bottom of the lubricating oil tank 9 and engage with the protective plate 15 to protect the brush body 14. The protective gear 13 is covered and a connecting frame 31 is fixedly installed on the upper end of the protective gear 13. The connecting frame 31 is elastically connected to the lubricating oil tank 9. A top shell wheel 16 is installed on the upper end of the connecting frame 31. During the rotation of the lubricating oil tank 9, the top shell wheel 16 will push against the traveling wheel set 2 to support the protective gear 13. Then the lubricating oil tank 9 continues to rotate upwards towards the traveling wheel set 2. At this time, the protective gear 13 will gradually move under the support of the traveling wheel set 2, thereby driving the protective gear 27 to rotate.

[0020] A lug 33 is rotatably mounted on the outer surface of the housing shaft 20. The end of the lug 33 is fixed to the lubricating oil tank 9. The lug 33 serves to support the housing shaft 20. A connecting lug 10 extends from the middle of the upper end of the protective shell 11. The end of the connecting lug 10 is fixed to one end of the housing shaft 20. The connecting lug 10 serves to connect the protective shell 11.

[0021] Two guide posts 29 are symmetrically embedded through the lower end of the connecting frame 31. Guide seats 28 are slidably installed on the outer surface of the two guide posts 29. The guide posts 29 and guide seats 28 serve to guide the connecting frame 31. The rear end of the guide seat 28 is fixed to the front end of the lubricating oil tank 9 near the middle.

[0022] An opening spring 30 is wound around the outside of the guide post 29. One end of the opening spring 30 is fixed to the lower end of the connecting frame 31, and the other end of the opening spring 30 is fixed to the upper end of the guide seat 28. When the lubricating oil tank 9 is flipped and reset, the opening spring 30 will push the connecting frame 31, thereby driving the protective tooth plate 13 to move, so as to drive the protective gear 27 to rotate, so that the protective shell 11 is opened, allowing the brush body 14 at the bottom of the lubricating oil tank 9 to be exposed again. A positioning cap 32 is coaxially embedded at the lower end of the guide post 29. The positioning cap 32 fits against the lower end of the guide seat 28 and plays the role of positioning the moving position of the guide post 29.

[0023] The retractable component includes a connecting shaft 23 installed at the upper front of the travel wheel set 2. The lubricating oil tank 9 is connected to the connecting shaft 23, which serves to support the lubricating oil tank 9. A retractable gear 26 is coaxially embedded at the end of the connecting shaft 23. A retractable toothed plate 8 meshes with the upper part of the retractable gear 26. The retractable toothed plate 8 is elastically connected to the travel wheel set 2. The cooperation between the retractable gear 26 and the retractable toothed plate 8 can flip the lubricating oil tank 9 and the V-shaped shovel head 12 to retract. A guide plate seat 21 is slidably installed on the outer side of the retractable toothed plate 8. The guide plate seat 21 is fixed to the travel wheel set 2 and serves to guide the retractable toothed plate 8. A fixing post 34 is elastically installed at the upper end of the guide plate seat 21. The fixing post 34 serves to lock the retractable toothed plate 8. A reset wheel 19 is connected to the upper end of the fixing post 34.

[0024] The lower end of the fixed column 34 passes through the upper end of the guide plate seat 21 and is pressed against the retractable toothed plate 8. The fixed column 34 and the guide plate seat 21 are slidably engaged. The upper end face of the retractable toothed plate 8 is provided with a fixing hole 25, which is aligned with the fixed column 34. The fixing hole 25 serves to cooperate with the fixed column 34. A retractable top frame 37 is fixedly installed on the front side of the track frame 1. The retractable top frame 37 is aligned with the retractable toothed plate 8. The cooperation between the retractable top frame 37 and the retractable toothed plate 8 can drive the connecting shaft 23 to rotate, so as to flip the lubricating oil tank 9 and the V-shaped shovel head 12 above the traveling wheel set 2. A reset inclined frame 3 is fixedly installed on the rear side of the track frame 1. The reset wheel 19 is aligned with the reset inclined frame 3. The cooperation between the reset wheel 19 and the reset inclined frame 3 can drive the fixed column 34 and the fixing hole 25 to separate.

[0025] A groove seat 22 is rotatably mounted on the outer surface of the connecting shaft 23. The lower end of the groove seat 22 is fixed to the traveling wheel assembly 2. The groove seat 22 serves to support the connecting shaft 23. An extension ear 24 extends from the upper rear edge of the lubricating oil tank 9. The end of the extension ear 24 is embedded in the connecting shaft 23. The extension ear 24 serves to fix the connecting shaft 23 and the lubricating oil tank 9 together. A fixing sleeve 17 is slidably mounted on the outer surface of the fixing column 34. The fixing sleeve 17 is fixed to the guide plate seat 21. The fixing sleeve 17 serves to fix the column. The fixed post 34 serves as a load-bearing component. A convex lug 36 is coaxially inlaid on the outer surface of the fixed post 34. The convex lug 36 is slidably installed inside the fixed sleeve 17. A compression spring 35 is wound around the outer side of the fixed post 34. The convex lug 36 is pushed by the compression spring 35. One end of the compression spring 35 is fixed to the inner top surface of the fixed sleeve 17, and the other end of the compression spring 35 is fixed to the upper end of the convex lug 36. The compression spring 35 can push the fixed post 34 out so that it can be inserted into the fixing hole 25.

[0026] A wheel frame 18 is fixedly installed on the upper end of the fixed column 34. The reset wheel 19 is coaxially installed on the outer surface of the wheel frame 18. The wheel frame 18 serves to support the reset wheel 19. A limiting rod 5 is fixedly installed on the rear end of the retractable toothed plate 8. An L-shaped seat 4 is slidably installed on the outer surface of the limiting rod 5. The limiting rod 5 serves to prevent the reset spring 7 from bending. The end of the L-shaped seat 4 is fixed to the traveling wheel set 2. A rod cap 6 is coaxially embedded on the end of the limiting rod 5. The rod cap 6 fits against the rear end of the L-shaped seat 4. The rod cap 6 serves to position the forward movement of the retractable toothed plate 8. A reset spring 7 is wound around the outside of the limiting rod 5. One end of the reset spring 7 is fixed to the front end of the L-shaped seat 4, and the other end of the reset spring 7 is fixed to the rear end of the retractable toothed plate 8. The reset spring 7 can push the retractable toothed plate 8 to drive the retractable gear 26 to rotate, thereby driving the lubricating oil tank 9 and the V-shaped shovel head 12 above the traveling wheel set 2 to flip and reset, so as to re-contact with the track frame 1.

[0027] During operation, the traveling wheel assembly 2 rolls forward on the track frame 1. At this time, the V-shaped shovel head 12 scrapes off the oil stains on the track frame 1. Simultaneously, lubricating oil from the lubricating oil tank 9 drips from the lower oil outlet onto the degreased track frame 1 and is coated by the brush body 14, ensuring even application of lubricating oil to the track frame 1. When the traveling wheel assembly 2 is about to reach the end point of the track frame 1, the retractable toothed plate 8 abuts against the retractable top frame 37, keeping the retractable toothed plate 8 stationary. The traveling wheel assembly 2 continues to move forward. During this process, the retractable gear 26 rolls on the retractable toothed plate 8, driving the connecting shaft 23 to rotate, thereby... When the lubricating oil tank 9 and the V-shaped shovel head 12 are flipped above the traveling wheel set 2, the fixing post 34 is pushed out by the compression spring 35 and inserted into the fixing hole 25 on the retractable toothed plate 8 to fix the flipped lubricating oil tank 9 and the V-shaped shovel head 12, so that they are detached from the track frame 1 to prevent the V-shaped shovel head 12 from damaging the lubricating oil layer during the movement of the traveling wheel set 2. At the same time, when the lubricating oil tank 9 is flipped above the traveling wheel set 2, its bottom will be in an upward position, so that the lubricating oil inside the lubricating oil tank 9 will no longer be discharged. When the lubricating oil tank 9 is flipped, the top shell wheel 16 will push against the traveling wheel set 2. On wheel set 2, the protective toothed plate 13 is supported. Then, the lubricating oil tank 9 continues to rotate upwards towards the wheel set 2. At this time, the protective toothed plate 13 gradually moves under the support of the wheel set 2, thereby driving the protective gear 27 to rotate. This allows the protective shell 11 at the end of the housing shaft 20 to rotate towards the bottom of the lubricating oil tank 9 and engage with the protective plate 15. The protective shell 11 and protective plate 15 cover the brush body 14 to prevent dust and other contaminants from adhering to the brush body 14 and causing lubricating oil contamination during application. When further cleaning is required, the wheel set 2 rolls backwards on the track frame 1. When group 2 is about to move to the end of track frame 1, the reset wheel 19 will fit against the reset inclined frame 3. Then the traveling wheel group 2 continues to move backward. At this time, the reset wheel 19 rolls along the inclined surface of the reset inclined frame 3 and gradually moves upward, thereby driving the fixed column 34 to move upward so as to disengage from the fixed hole 25 on the retractable toothed plate 8. This allows the retractable toothed plate 8 to be pushed back by the reset spring 7 without the restriction of the fixed column 34. This, in turn, causes the lubricating oil tank 9 and V-shaped shovel head 12 above the traveling wheel group 2 to flip and reset so as to re-contact with the track frame 1. Then the traveling wheel group 2 moves forward, and the track frame 1 can be cleaned again.
