Description

Technical Field

[0001] The invention relates to the technical field of ship lift maintenance, and in particular to a device and method for cleaning oil stains on a rack of a ship lift. Background Art

[0002] As one of the important navigation facilities of the Three Gorges hub, the Three Gorges Shiplift is an important part of the Three Gorges Project. It mainly provides a fast passage for passenger ships, cargo ships and special ships to pass through the dam. The ship passing scale is 3,000 tons. It is currently the largest and most technically difficult vertical shiplift in the world. The Three Gorges Shiplift is a rack and pinion climbing vertical one-stage shiplift. The rack is the load-bearing element of the drive system. Under normal working conditions, the pinion of the drive mechanism is meshed 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 shiplift is 113m, and the rack is arranged at a height of 118m along the tower column. When the shiplift cabin is running up and down, the dry oil centralized lubrication system intermittently sprays oil to the rack and pinion. Since the rack and pinion are open 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 accumulated on the rack will drip downward with the increase of temperature, strong wind and other factors. The oil will splash on the water surface, the deck of the cabin, the railings, etc., causing environmental pollution. In addition, the oil has high viscosity, and hard particles are easy to adhere to the working surface of the rack, which may cause equipment damage. Therefore, it is necessary to clean up the waste oil in time. At present, manual cleaning is mainly used, which is difficult and labor-intensive. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a device and method for cleaning oil stains on the rack of a ship lift. The device is fixedly installed on the rack guard on the cabin. As the cabin rises or falls, the device can automatically clean the oil stains on the rack and the end face. The device can effectively and automatically clean the oil stains on the rack without manual cleaning, which greatly reduces the maintenance cost and workload of the ship lift.

The first bevel tooth and the second bevel tooth are engaged and locked by a nut compression spring.

[0007] The torque adjustment mechanism includes a ratchet disc, which is fixedly mounted on the machine base and freely passes through the bracket fixed shaft. The ratchet disc is engaged with a pawl, and the upper end of the pawl is connected to a pull handle. The pull handle is slidably matched with a pull handle sleeve and is pushed upward by a spring; the pull handle sleeve is fixed on the bracket fixed shaft.

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

[0009] The end surface oil scraper is a V-shaped structure.

[0010] A guide plate is fixedly mounted on the lower end of the tooth top oil scraper plate.

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

[0012] The tooth surface oil scraper plate and the tooth top oil scraper plate are both non-metallic carbon fiber plates, and the surface of the fiber plates is plated with an oleophobic coating.

[0013] A method for cleaning oil stains on a ship lift rack comprises the following steps: Step 1: Initial positioning and installation: After the ship lift cabin is raised to the highest position, install the device at the corresponding position on the rack guard on the cabin; Step 2, adjust the end face oil scraper mechanism: rotate the adjusting nut clockwise, and the slider at the bottom of the oil tank of the end face oil scraper mechanism moves outward along the guide rail under the drive of the adjusting screw, the spring is compressed, and the tooth top scraper plate on the end face oil scraper mechanism is disengaged from the tooth top surface of the ship lift rack; rotate the adjusting nut counterclockwise, and the end face oil scraper mechanism pushes the slider at the bottom of the oil tank to move inward along the guide rail under the tension of the spring, and the tooth top scraper plate on the end face oil scraper mechanism contacts the tooth top surface of the rack; Step 3, adjust the gear surface oil scraping mechanism: press the pull handle to disengage the pawl from the ratchet disk, turn the pull handle sleeve to the left to increase the pressure between the gear surface oil scraping plate and the tooth surface of the ship lift rack; turn the pull handle sleeve to the right to reduce the pressure between the gear surface oil scraping plate and the tooth surface of the rack; when the pressure between the gear surface oil scraping plate and the tooth surface of the rack is adjusted to a suitable level, release the pull handle, and the pawl will self-lock with the ratchet disk under the action of the spring, so that the gear surface oil scraping plate and the tooth surface of the ship lift rack maintain a fixed pressing force; Step 4, cleaning of oil stains: operate the ship lift cabin to descend, and the device will descend with the cabin during the descent process, and the tooth surface scraper will scrape down the oil stains on the tooth roots, tooth surfaces and tooth top surfaces of the ship lift rack, and the oil stains will automatically fall into the oil tank under the action of gravity; the end surface scraper and tooth top scraper will scrape down the oil stains on the two side surfaces and tooth top surfaces of the ship lift rack during the descent process of the cabin, and the oil stains will automatically fall into the oil tank under the action of gravity; Step 5. When there is not much oil on the tooth roots and tooth surfaces, and only the sides and top surfaces of the rack need to be cleaned, press the handle in the torque adjustment mechanism to disengage the pawl from the ratchet disc, then rotate the handle sleeve to the rightmost end, release the handle to self-lock the pawl and the ratchet disc, at which point the entire tooth surface scraping mechanism is disengaged from the ship lift rack, and only the end surface scraping mechanism works; when the cabin rises or falls, the upper or lower end surface of the V-shaped scraping plate on the end surface scraping mechanism scrapes the oil on the two side surfaces and top surfaces of the rack of the ship lift into the oil tank.

[0014] The present invention provides a device and method for cleaning oil stains on a ship lift rack, which has the following technical effects: 1) By installing the device on the rack guard of the ship lift, the oil stains on the rack can be quickly cleaned as the cabin rises or falls, without the need for manual cleaning, which can effectively reduce the workload of maintenance personnel and improve the efficiency of cleaning the rack oil stains of the ship lift.

[0015] 2) The structure is simple and reliable, and the operation is convenient. The device has no power mechanism and cleans the oil stains on the rack by the rise or fall of the cabin. The tooth surface scraper and the tooth top scraper are equipped with safety protection mechanisms, which will not cause damage to the rack during use.

[0016] 3) By setting a tooth-shaped locking plate, it can prevent the tooth surface scraper plate from hooking the tooth surface of the ship lift rack, causing the tooth surface scraper mechanism to be broken due to excessive force, and the fragments falling on the ship lift rack, affecting the normal operation of the ship lift; or damaging the tooth surface of the ship lift rack during the operation of the ship lift.

[0017] 4) By setting a torque adjustment mechanism, the size of the pressing force between the tooth surface scraper and the tooth surface of the ship lift rack and whether it contacts the tooth surface of the ship lift rack can be adjusted. One of the functions of the torque adjustment mechanism is that when the device is not in use, the mechanism can be retracted by pulling the handle and fixed in place. Another function is that the torsion spring is equivalent to a buffer mechanism. During the oil cleaning process, the torsion of the torsion spring rotates in a small range, so that the scraper can scrape from the top of the rack to the root surface, and then from the root surface to the top surface of the tooth as the ship cabin descends, scraping oil back and forth. Without a torque adjustment mechanism, oil scraping cannot be achieved.

[0018] 5) By setting up the end face oil scraping mechanism, the oil scraped off by the tooth face oil scraping mechanism and the tooth top oil scraping plate can be collected; at the same time, the oil on both sides and the tooth top surface of the ship lift rack can also be cleaned.

[0019] 6) By setting up the end face oil scraping adjustment component, the end face oil scraping mechanism can be adjusted to slide elastically forward and backward, so that the tooth top scraping plate on the end face oil scraping mechanism always maintains elastic contact with the tooth top surface of the ship lift rack.

DETAILED DESCRIPTION

[0033] like Figure 1-2 As shown, a ship lift rack oil cleaning device includes a machine base 1, which is fixedly mounted on a rack guard 7 by 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 surface oil scraping mechanism 3 is installed below the tooth surface oil scraping mechanism 2, and an oil tank 302 is fixedly mounted on the end surface oil scraping mechanism 3. The end surface oil scraping mechanism 3 adjusts the contact force between the tooth top oil scraping plate 304 and the tooth top surface through the end surface oil scraping adjustment component 4. When the ship cabin descends, the tooth surface oil scraping mechanism 2 and the end surface oil scraping mechanism 3 can automatically scrape out the oil on the tooth end surface and both side surfaces of the ship lift rack 6, and the oil automatically falls into the oil tank 302 under the action of gravity.

[0034] Furthermore, the machine base 1 is welded from square steel pipes, and the machine base 1 is fixedly mounted on the rack guard 7 on the cabin by bolts, and rises or falls together with the cabin.

[0035] The device is arranged on the cabin and can be raised and lowered together with the cabin, so that the cabin can use the device to clean the oil stains on the rack during operation, and there is no need to provide the device with additional climbing power.

[0036] like Figure 3 As shown, further, the tooth surface oil scraping mechanism 2 includes a tooth surface oil scraping plate 201 , an oil scraping plate fixing shaft 202 , a toothed locking piece 203 , a bracket 204 , a fixing frame 205 and a bracket fixing shaft 206 .

[0037] Both ends of the tooth surface oil scraper plate 201 and the top of the bracket 204 are provided with through holes. After the oil scraper plate fixing shaft 202 passes through the holes on the tooth surface oil scraper plate 201 and the bracket 204, it can be locked by the nut 2033 to complete the installation.

[0038] In order to prevent the tooth surface scraper plate 201 from hooking the tooth surface of the ship lift rack 6, causing the tooth surface scraper mechanism 2 to be broken due to excessive force, and the fragments falling on the ship lift rack 6, damaging the tooth surface of the ship lift rack 6 during the operation of the ship lift, a tooth-shaped locking piece 203 is provided between the tooth surface scraper plate 201 and the bracket 204 as a safety device. The tooth surface scraper plate 201 and the bracket 204 are relatively locked by the tooth-shaped locking pieces 203 at both ends.

[0039] like Figure 7-8 As shown, the toothed locking piece 203 is a pair of plane bevel teeth, and the pair of plane bevel teeth are respectively a first plane bevel tooth 2031 and a second plane bevel tooth 2032. The first plane bevel tooth 2031 is fixedly mounted on the tooth surface oil scraper plate 201, and the second plane bevel tooth 2032 is fixedly mounted on the bracket 204. When the scraper plate fixing shaft 202 passes through the holes on the tooth surface oil scraper plate 201 and the bracket 204, the first plane bevel tooth 2031 and the second plane bevel tooth 2032 are engaged. A spring 2034 is sleeved on the scraper plate fixing shaft 202 outside the bracket 204, and a nut is threadedly connected to the scraper plate fixing shaft 202 outside the spring 2034, and is further locked by the nut and the spring 2034.

[0040] Under normal working conditions, the first plane bevel gear 2031 and the second plane bevel gear 2032 are in a meshing and locking state, the tooth surface scraper 201 and the scraper fixed shaft 202 remain relatively fixed, and the tooth surface scraper 201 scrapes off the oil stains on the surface of the rack 6 along the tooth surface as the ship lift descends.

[0041] When the downward pulling force of the tooth surface scraper plate 201 is greater than the locking force of the toothed locking plate 203 itself, the first plane bevel tooth 2031 installed on the tooth surface scraper plate 201 will rotate relative to the second plane bevel tooth 2032, and the tooth surface scraper plate 201 will flip upward and disengage from the tooth surface of the ship lift rack 6, protecting the tooth surface of the ship lift rack 6 from being scratched.

[0042] The lower end of the bracket 204 is sleeved on the bracket fixing shaft 206, and the bracket 204 and the bracket fixing shaft 206 are connected through a torsion spring 505. One end of the torsion spring 505 is fixedly installed on the lower end of the bracket 204, and the other end is fixed on the bracket fixing shaft 206.

[0043] The function of the torsion spring 505 is to keep the bracket 204 and the bracket fixing shaft 206 relatively fixed, and the bracket 204 can be rotated within a small range relative to the bracket fixing shaft 206 by the torsion of the torsion spring 505. In this way, the tooth surface oil scraper 201 can scrape the oil from the top of the tooth to the root surface of the tooth of the ship lift rack 6 and then from the root surface to the top surface of the tooth when the ship is lowered.

[0044] The bracket fixing shaft 206 is rotatably mounted on the fixing frame 205, and the fixing frame 205 is fixed on the machine base 1. A limiting plate is provided on the fixing frame 205 near the ship lift rack 6, and the limiting plate can support and limit the position of the bracket 204 toward the ship lift rack 6.

[0045] The contact force between the tooth surface oil scraper 201 and the tooth surface can be adjusted by the torque adjustment mechanism 5 .

[0046] The torque adjustment mechanism 5 includes a handle 501, a handle sleeve 502, a ratchet disc 503, a pawl 504, and a torsion spring 505. The handle sleeve 502 is fixed on the bracket fixed shaft 206, and the handle 501 is installed in the handle sleeve 502 and slidably cooperates with the handle sleeve 502. A spring is installed in the handle sleeve 502, and the spring pushes the handle 501 upward. A pawl 504 is installed at the lower end of the handle 501, and the pawl 504 is locked with the ratchet disc 503, and the ratchet disc 503 is fixedly installed on the machine base 1.

[0047] When the pull handle 501 is pressed to disengage the pawl 504 from the ratchet disc 503, the pull handle sleeve 502 is rotated to drive the bracket fixing shaft 206 to rotate, and the bracket fixing shaft 206 drives the bracket 204 to rotate. After adjusting the pressure between the tooth surface scraper plate 201 and the tooth surface of the ship lift rack 6, the pull handle 501 is released, and under the upward pushing action of the spring, the pull handle 501 moves up and drives the pawl 504 to engage with the ratchet disc 503 to self-lock, so that the tooth surface scraper plate 201 on the tooth surface scraper mechanism 2 and the tooth surface of the ship lift rack 6 maintain a fixed pressing force.

[0048] The end surface oil scraping mechanism 3 includes an end surface oil scraping plate 301 , an oil groove 302 , a guide plate 303 , and a tooth top oil scraping plate 304 .

[0049] The end surface oil scraper 301 is a V-shaped structure, and includes an oil scraper portion 3011, and a limit portion 3012 is provided outside the oil scraper portion 3011. The oil scraper portion 3011 is perpendicular to the limit portion 3012 and the two work together to drain the oil. The oil can be scraped when the cabin moves upward or downward, and the oil can be scraped into the oil tank 302.

[0050] The end faces of the end scraper plates 301 are in contact with the side faces of the rack, and the middle tooth top scraper plate end face 304 is in contact with the tooth top face of the ship lift rack 6. When the cabin rises or falls, the end scraper plates 301 and the tooth top scraper plates 304 can simultaneously scrape off the oil stains on the side faces and tooth top face of the rack, and the scraped oil stains automatically fall into the oil tank 302 under the action of gravity.

[0051] Preferably, a guide plate 303 is fixedly mounted on the tooth top scraper plate 304, and the guide plate 303 can maintain a safe distance between the tooth top scraper plate 304 and the rack to prevent the tooth top scraper plate 304 from being stuck during the rising or falling process.

[0052] The end surface oil scraping mechanism 3 can adjust the contact force between the tooth top oil scraping plate 304 and the tooth top surface of the ship lift rack 6 through the end surface oil scraping adjustment component 4.

[0053] The end surface oil scraping adjustment assembly 4 includes a connecting plate 401 , a compression spring 402 , an adjustment nut 403 , an adjustment screw 404 , a support 405 , a slider 406 , and a guide rail 407 .

[0054] One end of the adjusting screw 404 is fixedly welded to the connecting plate 401, and the connecting plate 401 is fixedly mounted on the oil tank 302 by 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 scraper plate 304 on the end face oil scraper mechanism 3 is pressed against the tooth top face. The end face of the adjusting nut 403 contacts the outer end face of the support 405.

[0055] There are two guide rails 407, which are fixedly mounted on the machine base 1, and there are four sliders 406. Two sliders 406 are mounted on each guide rail 407, and the top surface of the slider 406 is fixedly connected to the bottom surface of the oil groove 302. When the adjusting nut 403 is rotated, the tension of the spring 402 can keep the tooth top scraper plate 304 on the end surface scraper mechanism 3 in contact with the tooth top surface.

[0056] Furthermore, the tooth surface oil scraper plate 201 and the tooth top oil scraper plate 304 are both non-metallic carbon fiber plates, and the surface of the fiber plates is coated with an oleophobic coating to prevent grease adhesion.

[0057] A method for cleaning oil stains on a ship lift rack comprises the following steps: Step 1: Initial positioning and installation of the device: After the ship lift cabin is raised to the highest position, the device is installed at the corresponding position on the rack guard 7 on the cabin.

[0058] Step 2, adjust the end face oil scraper mechanism 3: rotate the adjustment nut 403 clockwise, and the slider 406 at the bottom of the oil groove 302 of the end face oil scraper mechanism 3 moves outward along the guide rail 407 under the drive of the adjustment screw 404, the spring 402 is compressed, and the tooth top scraper plate 304 on the end face oil scraper mechanism 3 is disengaged from the tooth top surface of the ship lift rack 6; rotate the adjustment nut 403 counterclockwise, and the end face oil scraper mechanism 3 pushes the slider 406 at the bottom of the oil groove 302 to move inward along the guide rail 407 under the tension of the spring 402, and the tooth top scraper plate 304 on the end face oil scraper mechanism 3 contacts the tooth top surface of the rack. By rotating the adjustment nut 403, it is possible to adjust whether the tooth top scraper plate 304 contacts the tooth top surface of the rack. The spring 402 can eliminate the gap during the working process to ensure that the tooth top scraper plate 304 is always in contact with the tooth top surface of the rack.

[0059] Step 3, adjust the tooth surface oil scraping mechanism 2: press the pull handle 501 to disengage the pawl 504 and the ratchet disk 503, and turn the pull handle sleeve 502 to the left to increase the pressure between the tooth surface oil scraping plate 201 and the tooth surface of the ship lift rack 6; turn the pull handle sleeve 502 to the right to 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 to an appropriate level, release the pull handle 501, and the pawl 504 and the ratchet disk 503 can self-lock, so that a fixed clamping force is maintained between the tooth surface oil scraping plate 201 and the tooth surface of the rack.

[0060] Step 4, cleaning oil stains: operate the ship lift cabin to move downward. During the downward movement of the cabin, the device moves downward with the cabin. The tooth surface scraper 201 scrapes the oil stains on the tooth roots, tooth surfaces and tooth top surfaces of the ship lift rack 6 downward, and the oil stains automatically fall into the oil tank 302 under the action of gravity. During the downward movement of the cabin, the end surface scraper 301 and the tooth top scraper 304 can scrape the oil stains on the two side surfaces and tooth top surfaces of the ship lift rack 6 with their V-shaped lower end surfaces, and the oil stains automatically fall into the oil tank 302 under the action of gravity.

[0061] Step 5. When there is not much oil on the tooth roots and tooth surfaces, and only the side surfaces and tooth top surfaces of the rack need to be cleaned, press the pull handle 501 in the torque adjustment mechanism 5 to disengage the pawl 504 from the ratchet disk 503, then rotate the pull handle sleeve 502 to the rightmost end, release the pull handle 501 to self-lock the pawl 504 and the ratchet disk 503, at this time the entire tooth surface oil scraping mechanism 2 is disengaged from the ship lift rack 6, and only the end surface oil scraping mechanism 3 can work; when the ship compartment rises or falls, the upper or lower end surface of the V-shaped oil scraping plate on the end surface oil scraping mechanism 3 can scrape the oil on the two side surfaces and tooth top surfaces of the ship lift rack 6 into the oil tank.
