Description

Technical Field

[0001] The present application relates to the technical field of auxiliary devices for gantry crane traveling mechanisms, and in particular to a waste oil collection device for bearings of gantry crane traveling mechanisms. Background Art

[0002] The gantry crane travel mechanism is mainly composed of a drive motor, roller shaft, roller and bearings. The bearings fix the position of the roller shaft, and the drive motor drives the roller to rotate, thereby driving the trolley to travel on the gantry crane.

[0003] To ensure the smooth operation of the bearing, it is necessary to inject enough lubricating oil into the bearing so that the inner and outer rings of the bearing have sufficient lubrication to ensure the normal rotation of the roller shaft. During operation, the rotation of the inner ring of the bearing will cause the lubricating oil to be gradually squeezed out and cover the outer wall of the inner ring of the bearing, causing pollution to the door machine structure near the bearing. In severe cases, the overflowed waste lubricating oil will be ignited and cause a fire, resulting in significant economic losses. Utility Model Content

[0004] The utility model aims to solve the above problems and thus provides a.

The bearing is disposed in the bearing seat, and the bearing seat is fixed to the outer ring of the bearing. A through hole is formed on the inner side end of the bearing seat, and the roller shaft passes through the through hole and is coaxially fixed to the inner ring of the bearing.

[0007] An oil collecting hopper is provided between the bearing seats and the rollers at both ends. The outer ends of the two oil collecting hoppers are provided with oil inlets, and the waste oil of the bearing enters the oil collecting hopper through the through hole and the oil inlet.

[0008] Compared with the prior art, the present invention adopting the above technical solution has the following beneficial effects:

[0009] The collecting device of the utility model can facilitate the collection of waste oil in the bearings of the gantry crane walking mechanism; the bearing is arranged inside the bearing seat, and a through hole is opened on the inner side of the bearing seat to facilitate the fixation of the bearing and the roller shaft. At the same time, the waste oil in the bearing can only flow to the inner side of the bearing seat through the through hole, and an oil collecting hopper is arranged between the inner end of the bearing seat and the roller, and the waste oil flowing out of the through hole is collected by the oil collecting hopper to avoid waste oil polluting the environment; the waste oil flowing out of the through hole will cover the inner end of the bearing seat and the roller shaft, and then flow into the oil collecting hopper.

[0010] As a preferred embodiment, a further technical solution of the present invention is:

[0011] The oil collecting hopper is equipped with an oil scraper rod, which is used to scrape the waste oil on the inner end of the bearing seat and divert it into the oil collecting hopper. By installing the oil scraper rod in the oil collecting hopper, the waste oil on the inner end of the bearing seat is scraped off and diverted into the oil collecting hopper together with the waste oil on the roller shaft, further improving the oil collection effect.

[0012] The diameter of the oil inlet is larger than the diameter of the inner end of the bearing seat, and the inner end of the bearing seat extends into the oil collecting hopper through the oil inlet. Through the above structure, the inner end of the bearing seat is inserted into the oil collecting hopper, which facilitates the waste oil flowing out of the through hole to flow into the oil collecting hopper.

[0022] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0023] Reference Figure 1-5 The embodiment of the present application discloses a waste oil collection device for the bearing 4 of the door crane walking mechanism, including a roller shaft 31, a roller 3 fixedly sleeved on the roller shaft 31, bearings 4 respectively connected to both ends of the roller shaft 31 and a bearing seat 1 connected to the bearing 4, the roller 3 is a synchronous wheel, and is connected to the synchronous belt transmission. When in use, the synchronous pulley is driven by the motor to rotate, thereby driving the synchronous belt to rotate, and then driving the roller 3 to rotate; the bearing 4 is arranged in the bearing seat 1. Specifically, the bearing seat 1 includes a cover plate 11, a cylinder 12 and a bottom plate 13. The cover plate 11 is connected to the top surface of the cylinder 12 by bolts, and the bottom surface of the cylinder 12 is integrally formed with the bottom plate 13. A limiting ring with the same diameter as the outer ring of the bearing 4 is fixed on the inner side of the cover plate 11. The limiting ring is fixed to the outer ring of the bearing 4. A through hole 14 is opened on the bottom plate 13. The roller shaft 31 passes through the through hole 14 and is coaxially fixed to the inner ring of the bearing 4.

[0024] An oil collecting hopper 2 is provided between the bearing seat 1 and the roller 3 at both ends. The interior of the oil collecting hopper 2 is an oil collecting cavity. The outer ends of the two oil collecting hoppers 2 are each provided with an oil inlet 22. The diameter of the oil inlet 22 is larger than the outer diameter of the inner end of the bearing seat 1. The inner end of the bearing seat 1 extends into the oil collecting hopper 2 through the oil inlet 22. There is a gap of 30mm-40mm between the inner end side wall of the bearing seat 1 and the oil inlet 22 of the oil collecting hopper 2 to prevent the oil collecting hopper 2 from rubbing against the bearing seat 1 when rotating. When the inner ring of the bearing 4 rotates driven by the roller shaft 31, the lubricating oil between the inner ring and the outer ring of the bearing 4 is squeezed out as it rotates and becomes waste oil. The waste oil enters the oil collecting hopper 2 through the through hole 14 and the oil inlet 22.

[0025] An oil scraping rod 21 is provided in the oil collecting hopper 2 , and the oil scraping rod 21 is used to scrape the waste oil on the roller shaft 31 and the inner end of the bearing seat 1 and guide it into the oil collecting hopper 2 .

[0026] In this embodiment, the oil collecting hopper 2 is assembled by plugging two semicircular troughs. Specifically, a plug-in strip 24 is fixed to the left end of the upper semicircular trough, and a plug-in strip 24 is fixed to the right end of the lower semicircular trough. When the two semicircular troughs are spliced, the plug-in strip 24 at the left end of the upper semicircular trough is inserted into the left end of the lower semicircular trough, and the plug-in strip 24 at the right end of the lower semicircular trough is inserted into the right end of the upper semicircular trough; the oil scraping rod 21 is welded and fixed to the inner wall of the ring position of the semicircular trough, and the inner wall of the two semicircular troughs is fixed. The side of the oil collecting hopper 2 is fixed to the side wall of the roller 3 by bolts. Each oil collecting hopper 2 is provided with at least two oil scraper rods 21, each arranged radially about the roller shaft 31. The front end of the oil scraper rod 21 is spaced apart from the roller shaft 31. Specifically, the spacing between the front end of the oil scraper rod 21 and the roller shaft 31 is 20mm-30mm. A protruding block protruding toward the bearing 4 is fixed to the front end of the oil scraper rod 21, near the bearing 4. The front end of the protruding block extends toward the bearing 4 through the gap between the through hole 14 and the roller shaft 31, but does not contact the bearing 4. Waste oil flowing out of the through hole 14 is drained to the inner wall of the oil collecting hopper 2 via the protruding block and the oil scraper rod 21. Waste oil flowing through the through hole 14 onto the roller shaft 31 is drained to the inner wall of the oil collecting hopper 2 via the oil scraper rod 21. The side of the oil scraper rod 21 near the bearing 4 scrapes waste oil from the inner and outer walls of the bearing seat 1 and drains it into the oil collecting hopper 2.

[0027] In this embodiment, the oil collecting hopper 2 is provided with an oil outlet 23, on which a detachable blocking plate is disposed. Specifically, the blocking plate is shaped to match the outer wall of the oil collecting hopper 2 near the oil outlet 23. The blocking plate is secured to the outer wall of the oil collecting hopper 2 near the oil outlet 23 by bolts. A rubber block is secured to the inside of the blocking plate. The size and shape of the rubber block are identical to those of the oil outlet 23. When the blocking plate is secured to the oil collecting hopper 2, the rubber block blocks the oil outlet 23, preventing leakage of waste oil from the oil collecting hopper 2. When the oil collecting hopper 2 contains a large amount of waste oil, the blocking plate can be opened to release the waste oil, allowing the device to be used for extended periods of time.

[0028] The working principle of this embodiment is:

[0029] The roller shaft 31, roller 3, oil collecting hopper 2, bearing seat 1 and bearing 4 of this embodiment are assembled in advance. When the roller shaft 31 rotates, it drives the roller 3 and the inner ring of the bearing 4 to rotate, and at the same time drives the oil collecting hopper 2 fixed on both sides of the roller 3 to rotate. The scraper in the oil collecting hopper 2 rotates with the oil collecting hopper 2. When the inner ring of the bearing 4 rotates in the bearing seat 1, the lubricating oil between the inner ring of the bearing 4 and the outer ring of the bearing 4 is gradually squeezed out during the rotation process, and the waste oil in the bearing seat 1 flows out through the through hole 14. The lubricating oil flowing out of the through hole 14 is scraped off by the protruding block and the scraper rod 21 and drained to the inner wall of the oil collecting hopper 2. The waste oil collected on the inner wall of the oil collecting hopper 2 is always gathered on the inner wall of the oil collecting hopper 2 under the action of centrifugal force, preventing the waste oil from flowing out from the oil inlet 22.

[0030] The collecting device of the present invention can facilitate the collection of waste oil in the bearing 4 of the gantry crane walking mechanism; the bearing 4 is arranged inside the bearing seat 1, and a through hole 14 is opened on the inner side of the bearing seat 1 to facilitate the fixation of the bearing 4 and the roller shaft 31. At the same time, the waste oil of the bearing 4 can only flow out from the through hole 14, and an oil collecting hopper 2 is arranged between the inner end of the bearing seat 1 and the roller 3, and the waste oil flowing out of the through hole 14 is collected by the oil collecting hopper 2 to avoid waste oil polluting the environment; the waste oil flowing out of the through hole 14 will cover the inner end of the bearing seat 1 and the roller shaft 31, and by arranging an oil scraper rod 21 in the oil collecting hopper 2, the waste oil on the inner side of the bearing seat 1 is scraped off and drained into the oil collecting hopper 2 together with the waste oil on the roller shaft 31, thereby further increasing the oil collection effect.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. Any equivalent changes made using the contents of the present invention specification and its drawings are included in the scope of the present invention.
