Description

Technical Field

[0001] The utility model relates to the technical field of ship lift maintenance, in particular to an oil stain cleaning device for the rack of a gear-rack climbing ship lift. Background Art

[0002] As one of the important navigation facilities of the Three Gorges Project, the Three Gorges ship lift is an important part of the Three Gorges Project. It mainly provides a fast dam-crossing channel for passenger ships, cargo ships and special ships. The ship passing scale is 3,000 tons, and it is currently the largest and most technically difficult vertical ship lift in the world. The Three Gorges ship lift is a gear-rack climbing type vertical first-class ship lift. The rack is a load-bearing component of the drive system. Under normal working conditions, the pinion of the drive mechanism meshes with the rack, and the load of the drive mechanism is transmitted to the concrete structure through the rack. The maximum lifting height of the ship lift is 113m, and the height of the rack arranged along the tower column elevation is 118m. When the ship chamber of the ship lift moves up and down, the gear and rack are intermittently sprayed with lubricating oil by the centralized grease lubrication system. Since the gear and rack are open-type lubrication, excess grease will accumulate at both ends of the rack. With the long-term operation of the ship lift, a large amount of oil stains accumulated on the rack will drip down due to factors such as temperature rise and strong wind. The oil stains will splash on the water surface, the deck of the ship chamber, the railing, etc., causing environmental pollution. Moreover, the oil stains have high viscosity, and hard particles are easily attached to the working surface of the rack, which may cause equipment damage. Therefore, it is necessary to clean up the waste oil stains in time. At present, manual cleaning is mainly used, which is difficult and laborious. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an oil stain cleaning device for the rack of a gear-rack climbing ship lift. The device is fixedly installed on the rack guard of the ship chamber. As the ship chamber rises or falls, the device can automatically remove the oil stains on the rack and the end face. Through the device, the oil stains on the rack can be effectively and automatically cleaned, without manual cleaning, greatly reducing the maintenance cost and workload of the ship lift.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0005] An oil stain cleaning device for the rack of a gear-rack climbing ship lift includes a machine base, the machine base is installed on the rack guard, and the rack guard is installed on the ship chamber and moves up and down with the ship chamber; a tooth surface oil scraping mechanism is installed on the machine base, the tooth surface oil scraping mechanism contacts the tooth surface of the ship lift rack and adjusts the pressing force through a torsion adjusting mechanism; an end face oil scraping mechanism is installed below the tooth surface oil scraping mechanism, and the end face oil scraping mechanism receives the oil stains and adjusts the contact and separation with the tooth top surface of the ship lift rack through an end face oil scraping adjusting component.

[0006] The tooth surface oil scraping mechanism includes a tooth surface oil scraping plate, which is installed on the bracket through an oil scraping plate fixing shaft, and the tooth surface oil scraping plate and the bracket are relatively locked through a toothed locking piece; the lower end of the bracket is fixedly connected to the bracket fixing shaft, and the bracket fixing shaft is rotatably installed on the fixed frame, and the fixed frame is fixedly installed on the machine base, and the bracket fixing shaft and the fixed frame are adjusted through a torque adjusting mechanism.

[0007] The torque adjusting mechanism includes a ratchet disc, which is fixedly installed on the machine base and freely passes through the bracket fixing shaft, the ratchet disc meshes with the pawl, the upper end of the pawl is connected to the pull handle, and the pull handle is slidably matched with the pull handle sleeve and is jacked up by a spring; the pull handle sleeve is fixed on the bracket fixing shaft.

[0008] The end face oil scraping mechanism includes a tooth top oil scraping plate, which contacts the tooth top surface of the shiplift rack, end face oil scraping plates are fixed at the left and right ends of the tooth top oil scraping plate, and the end face oil scraping plates contact the two side faces of the shiplift rack; an oil groove is fixed at the lower end of the tooth top oil scraping plate.

[0009] The end face oil scraping plate is of a V-shaped structure.

[0010] A guide plate is fixedly installed at the lower end of the tooth top oil scraping plate.

[0011] The end face oil scraping adjustment assembly includes an adjustment screw, one end of the adjustment screw is connected to the oil groove, the lower end of the oil groove is slidably arranged on the guide rail through a slider, and the guide rail is fixed on the machine base; the other end of the adjustment screw freely passes through the support and is threadedly connected to an adjustment nut; a compression spring is sleeved on the adjustment screw between the connecting plate and the support.

[0012] Both the tooth surface oil scraping plate and the tooth top oil scraping plate are non-metallic carbon fiber plates, and the surface of the fiber plate is plated with an oil-repellent coating.

[0013] The utility model provides a gear-rack climbing type shiplift rack oil stain cleaning device, which has the following technical effects:

[0014] 1). By installing this device on the rack guard of the shiplift, the oil stains on the rack can be quickly cleaned up as the ship chamber rises or falls, without the need for manual cleaning again, which can effectively reduce the workload of maintenance personnel and improve the efficiency of cleaning the oil stains on the shiplift rack.

[0015] 2). The structure is simple and reliable, and the operation is convenient. The device has no power mechanism, and the oil stains on the rack are cleaned up while relying on the rise or fall of the ship chamber. Both the tooth surface oil scraping plate and the tooth top oil scraping plate are provided with safety protection mechanisms, and the rack will not be damaged during use.

[0016] 3). By setting the toothed locking piece, it can prevent the oil scraping plate on the tooth surface from hooking the tooth surface of the shiplift rack, resulting in excessive force on the oil scraping mechanism on the tooth surface and fracture, with debris falling on the shiplift rack and affecting the normal operation of the shiplift; or damaging the tooth surface of the shiplift rack during the operation of the shiplift.

One function of the torque adjustment mechanism is that when the device is not in use, the mechanism can be retracted by pulling the handle to fix it and make it inoperative. Another function is that the torsion spring is equivalent to a buffer mechanism. During the oil cleaning process, it can rotate within a small range through the torsion of the torsion spring, enabling the oil scraping plate to scrape from the tooth top to the tooth root surface and then from the tooth root surface to the tooth top surface of the rack when the ship chamber descends, scraping the oil back and forth. Without the torque adjustment mechanism, it is impossible to achieve oil scraping.

[0018] 5). By setting the end face oil scraping mechanism, it can not only collect the oil scraped by the oil scraping mechanism on the tooth surface and the oil scraping plate on the tooth top; at the same time, it can also clean the oil on both side faces and the tooth top surface of the shiplift rack.

[0019] 6). By setting the end face oil scraping adjustment component, the end face oil scraping mechanism can be elastically slid and adjusted back and forth, so that the oil scraping plate on the tooth top of the end face oil scraping mechanism always keeps elastic contact with the tooth top surface of the shiplift rack.

Specific embodiments

[0034] As Figure 1-2 shown, an oil stain cleaning device for a ship lift rack of a gear-rack climbing type includes a machine base 1, and the machine base 1 is fixedly installed on the rack guard 7 through bolts. A tooth surface oil scraping mechanism 2 is installed on the machine base 1, and the tooth surface oil scraping mechanism 2 adjusts the pressing force between the tooth surface oil scraping plate 201 and the tooth surface of the ship lift rack 6 through a torque adjustment mechanism 5. An end face oil scraping mechanism 3 is installed below the tooth surface oil scraping mechanism 2, and an oil groove 302 is fixedly installed on the end face oil scraping mechanism 3. The end face oil scraping mechanism 3 adjusts the contact force between the tooth top oil scraping plate 304 and the tooth top surface through an end face oil scraping adjustment assembly 4. When the ship chamber descends, the tooth surface oil scraping mechanism 2 and the end face oil scraping mechanism 3 can automatically scrape the oil stains on the tooth end face and both side surfaces of the ship lift rack 6, and the oil stains automatically fall into the oil groove 302 under the action of gravity.

[0035] Furthermore, the machine base 1 is welded by square steel pipes, and the machine base 1 is fixedly installed on the rack guard 7 on the ship chamber through bolts, and rises or descends together with the ship chamber.

[0036] The device is arranged on the ship chamber and can rise and fall together with the ship chamber, so that the device can be used to clean the oil stains on the rack during the working process of the ship chamber, and there is no need to provide additional climbing power for the device.

[0037] As shown Figure 3 in the figure, further, the tooth surface oil scraping mechanism 2 includes a tooth surface oil scraping plate 201, an oil scraping plate fixing shaft 202, a tooth-shaped locking piece 203, a bracket 204, a fixing bracket 205 and a bracket fixing shaft 206.

[0038] Perforations are provided at both ends of the tooth surface oil scraping plate 201 and the top end of the bracket 204. After the oil scraping plate fixing shaft 202 passes through the holes on the tooth surface oil scraping plate 201 and the bracket 204, it can be locked by a nut to complete the installation.

[0039] To prevent the tooth surface oil scraping plate 201 from catching the tooth surface of the shiplift rack 6, resulting in excessive force on the tooth surface oil scraping mechanism 2 and causing it to break, with debris falling on the shiplift rack 6 and damaging its tooth surface during the operation of the shiplift. A tooth-shaped locking piece 203 is used as a safety device between the tooth surface oil scraping plate 201 and the bracket 204. The tooth surface oil scraping plate 201 and the bracket 204 are relatively locked by the tooth-shaped locking pieces 203 at both ends.

[0040] As shown Figure 7-8 in the figure, the tooth-shaped locking piece 203 is a pair of planar bevel gears. The pair of planar bevel gears are respectively a first planar bevel gear 2031 and a second planar bevel gear 2032. The first planar bevel gear 2031 is fixedly installed on the tooth surface oil scraping plate 201, and the second planar bevel gear 2032 is fixedly installed on the bracket 204. A spring is sleeved on the oil scraping plate fixing shaft 202 outside the bracket 204, and a nut is threadedly connected to the oil scraping plate fixing shaft 202 outside the spring.

[0041] Under normal working conditions, the first planar bevel gear 2031 and the second planar bevel gear 2032 are in a meshed and locked state, and the tooth surface oil scraping plate 201 remains relatively fixed with respect to the oil scraping plate fixing shaft 202. The tooth surface oil scraping plate 201 scrapes the oil stain on the surface of the rack 6 along with the downward movement of the shiplift.

[0042] When the downward pulling force of the tooth surface oil scraping plate 201 is greater than the locking force of the tooth-shaped locking piece 203 itself, the first planar bevel gear 2031 installed on the tooth surface oil scraping plate 201 will rotate relative to the second planar bevel gear 2032, and the tooth surface oil scraping plate 201 will flip upward to disengage from the tooth surface of the shiplift rack 6, protecting the tooth surface of the shiplift rack 6 from being scratched.

[0043] The bracket 204 is sleeved on the bracket fixing shaft 206, and the bracket 204 and the bracket fixing shaft 206 are connected by a torsion spring 505. One end of the torsion spring 505 is fixedly installed at the lower end of the bracket 204, and the other end is fixed on the bracket fixing shaft 206.

[0044] The function of the torsion spring 505 is to keep the relative fixation between the support 204 and the support fixed shaft 206, and the support 204 can rotate relative to the support fixed shaft 206 within a small range through the torsion of the torsion spring 505. In this way, when the tooth surface oil scraper 201 descends with the ship chamber, it can scrape from the tooth top of the ship lift rack 6 to the tooth root surface, and then from the tooth root surface to the tooth top surface, scraping oil reciprocally.

[0045] The support fixed shaft 206 is installed on the machine base 1 through the fixing frame 205, and the support fixed shaft 206 can rotate around its own axis relative to the fixing frame 205. A limiting plate is arranged on one side of the fixing frame 205 close to the ship lift rack 6, and the limiting plate can position and limit the position of the support 204 on the side facing the ship lift rack 6.

[0046] The contact force between the tooth surface oil scraper 201 and the tooth surface can be adjusted through the torsion adjusting mechanism 5.

[0047] The torsion adjusting mechanism 5 includes a pull handle 501, a pull handle sleeve 502, a ratchet disc 503, a ratchet pawl 504, and a torsion spring 505. The pull handle 501 is installed on the pull handle sleeve 502 and is slidably matched with the pull handle sleeve 502. A spring is installed on the pull handle 501, and the ratchet pawl 504 is installed at its lower end. The ratchet disc 503 is fixedly installed on the machine base 1, and the ratchet disc 503 is used in cooperation with the ratchet pawl 504. The pull handle sleeve 502 is fixed on the support fixed shaft 206.

[0048] When the pull handle 501 is pressed to disengage the ratchet pawl 504 from the ratchet disc 503, rotating the pull handle sleeve 502 can drive the support fixed shaft 206 to rotate, and the support fixed shaft 206 drives the support 204 to rotate. After adjusting the pressure between the tooth surface oil scraper 201 and the tooth surface of the rack, release the pull handle 501. Under the upward pushing action of the spring, the pull handle 501 moves upward and drives the ratchet pawl 504 to engage with the ratchet disc 503 for self-locking, so as to keep a fixed pressing force between the tooth surface oil scraper 201 on the tooth surface oil scraping mechanism 2 and the tooth surface of the ship lift rack 6.

[0049] The end face oil scraping mechanism 3 includes an end face oil scraper 301, an oil groove 302, a guide plate 303, and a tooth top oil scraper 304.

[0050] The end face oil scraper 301 is of a V-shaped structure, and a limiting plate is arranged on the outer side of the V-shaped structure. The limiting plate and the inclined surface of the end face oil scraper 301 act together to drain the oil stain. It can scrape oil during the upward or downward movement of the ship chamber, and can scrape the oil stain into the oil groove 302.

[0051] The end face oil scraping plate 301 has its two side end faces in contact with the two side faces of the rack, and the end face 304 of the tooth top oil scraping plate in the middle is in contact with the tooth top face of the ship lift rack 6. When the ship chamber ascends or descends, the end face oil scraping plate 301 and the tooth top oil scraping plate 304 can simultaneously scrape the oil stains on the two side faces and the tooth top face of the rack, and the scraped oil stains automatically fall off into the oil sump 302 under the action of gravity.

[0052] Preferably, a guide plate 303 is fixedly installed on the tooth top oil scraping plate 304. The guide plate 303 can keep a safe distance between the tooth top oil scraping plate 304 and the rack, preventing the tooth top oil scraping plate 304 from being stuck during the ascending or descending process.

[0053] The end face oil scraping mechanism 3 can adjust the contact force between the tooth top oil scraping plate 304 and the tooth top face of the ship lift rack 6 through the end face oil scraping adjustment assembly 4.

[0054] The end face oil scraping adjustment assembly 4 includes a connecting plate 401, a compression spring 402, an adjusting nut 403, an adjusting screw 404, a support 405, a slider 406, and a guide rail 407.

[0055] One end of the adjusting screw 404 is fixedly welded to the connecting plate 401, and the connecting plate 401 is fixedly installed on the oil sump 302 through bolts. The other end of the adjusting screw 404 freely passes through the support 405 and is threadedly connected to the adjusting nut 403. The support 405 is fixedly connected to the machine base 1. A compression spring 402 is sleeved on the adjusting screw 404 between the connecting plate 401 and the support 405. Under the elastic force of the compression spring 402, the tooth top oil scraping plate 304 on the end face oil scraping mechanism 3 is pressed tightly against the tooth top face. And the end face of the adjusting nut 403 is in contact with the outer end face of the support 405.

[0056] There are 2 guide rails 407, which are respectively fixedly installed on the machine base 1. There are a total of 4 sliders 406, and 2 sliders 406 are respectively installed on each guide rail 407 in a mating manner. The top face of the slider 406 is fixedly connected to the bottom face of the oil sump 302. When the adjusting nut 403 is rotated, the tooth top oil scraping plate 304 on the end face oil scraping mechanism 3 can always be kept in contact with the tooth top face through the tension of the spring 402.

[0057] Furthermore, the tooth face oil scraping plate 201 and the tooth top oil scraping plate 304 are both non-metallic carbon fiber plates, and the surface of the fiber plate is coated with an oil-repellent coating to prevent grease adhesion.

[0058] A method for cleaning the oil stains on the ship lift rack includes the following steps:

[0059] Step 1: Initial positioning and installation of the device: After the ship lift chamber is raised to the highest position, install this device at the corresponding position on the rack guard 7 on the chamber.

[0060] Step 2. Adjust the end face oil scraping mechanism 3: Rotate the adjusting nut 403 clockwise. Driven by the adjusting screw 404, the slider 406 at the bottom of the oil groove 302 of the end face oil scraping mechanism 3 moves outward along the guide rail 407, the spring 402 is compressed, and the tooth top oil scraping plate 304 on the end face oil scraping mechanism 3 disengages from the tooth top surface of the ship lift rack 6; Rotate the adjusting nut 403 counterclockwise. Under the tension of the spring 402, the end face oil scraping mechanism 3 pushes the slider 406 at the bottom of the oil groove 302 to move inward along the guide rail 407, and the tooth top oil scraping plate 304 on the end face oil scraping mechanism 3 contacts the tooth top surface of the rack. By rotating the adjusting nut 403, it can be adjusted whether the tooth top oil scraping plate 304 contacts the tooth top surface of the rack. The spring 402 can eliminate the gap during the working process and ensure that the tooth top oil scraping plate 304 always contacts the tooth top surface of the rack.

[0061] Step 3. Adjust the tooth surface oil scraping mechanism 2: Press the pull handle 501 to disengage the ratchet pawl 504 from the ratchet disc 503. Turning the pull handle sleeve 502 to the left can increase the pressure between the tooth surface oil scraping plate 201 and the tooth surface of the ship lift rack 6; Turning the pull handle sleeve 502 to the right can reduce the pressure between the tooth surface oil scraping plate 201 and the tooth surface of the rack; When the pressure between the tooth surface oil scraping plate 201 and the tooth surface of the rack is adjusted appropriately, after releasing the pull handle 501, the ratchet pawl 504 and the ratchet disc 503 can be self-locked, so that a fixed pressing force is maintained between the tooth surface oil scraping plate 201 and the tooth surface of the rack.

[0062] Step 4. Oil stain cleaning: Operate the ship lift chamber to descend. During the descending process of the chamber, this device descends together with the chamber. The tooth surface oil scraping plate 201 scrapes the oil stains on the tooth root, tooth surface and tooth top surface of the ship lift rack 6 downward. Under the action of gravity, the oil stains automatically fall off into the oil groove 302; During the descending process of the chamber, the lower V-shaped end face of the end face oil scraping plate 301 and the tooth top oil scraping plate 304 can scrape the oil stains on the two side faces and the tooth top surface of the ship lift rack 6 downward. Under the action of gravity, the oil stains automatically fall off into the oil groove 302.

[0063] Step 5. When there is not much oil stain on the tooth root and tooth surface and only the oil stains on the side face and tooth top surface of the rack need to be cleaned, press the pull handle 501 in the torque adjusting mechanism 5 to disengage the ratchet pawl 504 from the ratchet disc 503, and then rotate the pull handle sleeve 502 to the rightmost end. Release the pull handle 501 to make the ratchet pawl 504 and the ratchet disc 503 self-lock. At this time, the entire tooth surface oil scraping mechanism 2 disengages from the ship lift rack 6, and only the end face oil scraping mechanism 3 can work; When the chamber rises or descends, the upper or lower end face of the V-shaped oil scraping plate on the end face oil scraping mechanism 3 can scrape the oil stains on the two side faces and the tooth top surface of the ship lift rack 6 into the oil groove.
