Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gate opening and closing risk control, in particular to a reservoir gate screw jam risk prevention and control device. BACKGROUND

[0002] The opening and closing mode of the reservoir gate is mainly opened and closed by the hoist, which is divided into screw hoist, winch hoist and hydraulic hoist. Among them, the body of the screw hoist is placed on the gate bridge, the screw passes through the through hole of the gate bridge, the body drives the screw to rise and fall, one end of the screw is connected with the gate to achieve the lifting of the gate. The screw hoist has simple structure and low cost, and is mainly used for small flat gate and arc gate.

[0003] Since the screw hoist is driven to rise and fall by the rotation of the screw disc mother in the body and the screw thread connected with it, a large friction will be generated between the screw and the screw disc mother, which will cause wear of the screw and the screw disc mother. If the screw surface is not smeared with lubricating oil for a long time, the wear degree and rust speed of the screw and the screw disc mother will be increased, which will seriously affect the performance and service life of the hoist, and also will cause a large safety hazard.

[0004] The present application believes that the above-mentioned related technology has the following defects: when smearing lubricating oil on the screw, the screw needs to be lifted first, and then the residual oil dirt, silt and other impurities on the screw are scraped off manually, and then the screw surface is smeared with lubricating oil. When dealing with a long screw, the screw needs to be lifted in sections for scraping, smearing and other operations, which is relatively complicated. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the problem that smearing lubricating oil on the screw is relatively complex, the present application provides a reservoir gate screw jam risk prevention and control device.

[0006] The reservoir gate screw jam risk prevention and control device provided by the present application adopts the following technical scheme:

[0007] A reservoir gate screw jam risk prevention and control device, comprising a spray pipe arranged on the gate bridge and passing through the through hole, a storage barrel is arranged on the side of the gate bridge away from the water surface, the spray pipe is in communication with the storage barrel, the spray opening end of the spray pipe is aligned with the screw, and a scraping assembly for scraping the impurities on the screw is further arranged on the gate bridge.

[0008] By adopting the technical scheme, when the screw rod needs to be smeared with lubricating oil, the staff only needs to open the machine body, make the screw rod rise, pour the lubricating oil into the storage barrel, and then the scraping assembly scrapes off the dirt, sand and other impurities on the screw rod, and then the lubricating oil in the storage barrel flows into the spray pipe and is sprayed onto the screw rod from the spray pipe, so that the surface of the screw rod is smeared with new lubricating oil, and then the screw rod is lowered, and the operation is simple.

[0009] Optionally, a threaded cover is threadedly connected to the opening of the storage barrel, and a pressing plate is slidably arranged in the storage barrel, and one end of the pressing plate close to the threaded cover is fixedly connected with a pressing rod penetrating through the threaded cover.

[0010] By adopting the technical scheme, the threaded cover is unscrewed, the lubricating oil is poured into the storage barrel, when the lubricating oil in the storage barrel is relatively viscous and difficult to flow in the spray pipe by gravity alone, the threaded cover is screwed and then the pressing rod is pressed downward, at this time the lubricating oil is extruded by the pressing plate and sprayed out of the spray pipe, so as to adapt to more types of lubricating oil.

[0011] Optionally, the spray pipe is communicated with an elastic nozzle at the nozzle, and the elastic nozzle is in a converging shape.

[0012] By adopting the technical scheme, when the lubricating oil in the storage barrel is relatively thin, the converging elastic nozzle has a small diameter, so that the flow of the lubricating oil is small and the waste of the lubricating oil is reduced; when the lubricating oil in the storage barrel is relatively viscous, the diameter of the elastic nozzle is expanded by the pressure of the pressing plate, so that the lubricating oil is smoothly sprayed out of the elastic nozzle.

[0013] Optionally, the bottom of the gate bridge is fixedly connected with a feeding cylinder, and the elastic nozzle extends into the feeding cylinder.

[0014] By adopting the technical scheme, when the lubricating oil sprayed out of the elastic nozzle is relatively viscous, the lubricating oil is extruded and fills the space between the feeding cylinder and the screw rod, so that the screw rod is uniformly and comprehensively smeared with the lubricating oil, thereby improving the lubrication and rust prevention effect of the screw rod, and reducing the risk of the screw rod due to rust and other phenomena.

[0015] Optionally, the scraping assembly comprises a rotating ring rotatably connected to the bottom of the feeding cylinder and a scraper arranged on the rotating ring, and the scraper is matched with the threaded part of the screw rod.

[0016] By adopting the technical scheme, when the screw rod rises, the screw rod does not rotate, and the scraper closely abuts against the screw rod, so that the rotating ring rotates and the scraper performs circumferential motion along the screw rod, and the impurities on the surface of the screw rod are scraped off by the scraper.

[0017] Optionally, the scraper is hinged at the bottom of the rotating ring, the rotating ring is provided with a first elastic member for driving the scraper to rotate towards the screw rod, and the feeding cylinder is provided with a limiting assembly for limiting the rotation of the rotating ring.

[0018] By adopting the above technical scheme, when the screw rod rises, the rotating ring and the scraper on the rotating ring rotate to scrape off the sundries on the screw rod; when the screw rod descends, the limiting assembly controls the rotating ring to be unable to rotate, at this time, the scraper is shaken by the pushing of the screw rod and the action of the first elastic member, thereby effectively reducing the quality of the new lubricating oil hung on the screw rod by the scraper.

[0019] Optionally, the limiting assembly comprises a pawl arranged on the bottom wall of the feeding cylinder, a tooth portion provided on the circumferential wall of the rotating ring and matched with the pawl, and a second elastic member arranged on the feeding cylinder and used for driving the pawl to abut against the tooth portion.

[0020] By adopting the above technical scheme, when the screw rod descends, the pawl abuts against the straight surface of the tooth portion, thereby making the rotating ring unable to rotate, i.e. the scraper is also unable to rotate, and the surface area of the screw rod scraped by the scraper is effectively reduced.

[0021] Optionally, the circumferential wall of the pressing plate is provided with a sealing ring.

[0022] By adopting the above technical scheme, when the pressing rod is pushed downward, the pressing plate extrudes the lubricating oil in the storage barrel, and the sealing ring improves the sealing property between the pressing plate and the inner wall of the storage barrel, thereby avoiding the lubricating oil from leaking out between the inner wall of the storage barrel and the pressing plate.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. When the screw rod needs to be coated with lubricating oil, the machine body is started to make the screw rod rise, and the lubricating oil is poured into the storage barrel, the scraper first scrapes off the sundries such as oil stains and sand on the screw rod, then the lubricating oil in the storage barrel flows into the spray pipe and is sprayed from the spray pipe to the screw rod, so that the screw rod is coated with new lubricating oil, and part of the lubricating oil is transferred to the spiral disc mother when the screw rod coated with new lubricating oil passes through the spiral disc mother, and the screw rod can be lowered after coating, which is relatively simple to operate.

[0025] 2. The threaded cap is unscrewed, and the lubricating oil is poured into the storage barrel, when the lubricating oil in the storage barrel is relatively viscous and difficult to flow in the spray pipe only by gravity, the threaded cap is screwed, and then the pressing rod is pressed downward, at this time, the lubricating oil is extruded by the pressing plate and sprayed from the spray pipe, so as to adapt to more types of lubricating oil.

[0026] 3. When the lubricating oil in the storage tank is relatively thin, the elastic nozzle with a closed end has a small caliber, thereby reducing the flow of lubricating oil and reducing waste of lubricating oil; when the lubricating oil in the storage tank is relatively thick, the pressure of the lubricating oil pressing plate enlarges the caliber of the elastic nozzle, thereby enabling the lubricating oil to be smoothly sprayed from the elastic nozzle.

DETAILED DESCRIPTION

[0031] The following will be described in detail with reference to the accompanying drawings Figures 1-3 The present application will be further described in detail.

[0032] The embodiment of the present application discloses a reservoir gate screw rod jamming risk prevention and control device. Referring to Figure 1 and Figure 2 , the reservoir gate opening and closing risk control device comprises a spray pipe 11 arranged on the gate bridge 61 and penetrating through a through hole, a storage tank 12 is arranged on the side of the gate bridge 61 away from the water surface, the spray pipe 11 is in communication with the storage tank 12, the spray opening end of the spray pipe 11 is aligned with the screw rod 63, the elastic nozzle 111 can be made of rubber, and the gate bridge 61 is further provided with a scraping assembly 2 for scraping sundries on the screw rod 63.

[0033] When it is necessary to apply lubricating oil to the screw rod 63, the machine body 62 is only needed to be opened, the screw rod 63 is lifted, and at the same time, the lubricating oil is poured into the storage tank 12, the scraping assembly 2 first scrapes the oil stains, silt and other sundries on the screw rod 63, then the lubricating oil in the storage tank 12 flows into the spray pipe 11 and is sprayed from the spray pipe 11 to the screw rod 63, so that the screw rod 63 is coated with new lubricating oil, and at the same time, the screw rod 63 coated with new lubricating oil will transfer part of the lubricating oil to the spiral disc when passing through the spiral disc, and after the coating is completed, the screw rod 63 can be lowered, and the operation is relatively simple.

[0034] With reference to Figure 2 , the opening of the storage barrel 12 is threadedly connected with a threaded cover 31, and a pressing plate 32 matched with the storage barrel 12 is slidably arranged in the storage barrel 12. An end of the pressing plate 32 close to the threaded cover 31 is fixedly connected with a pressing rod 33 penetrating through the threaded cover 31, and a sealing ring 321 is bonded to the peripheral wall of the pressing plate 32. The sealing ring 321 is a rubber ring to improve the sealing performance between the pressing plate 32 and the inner wall of the storage barrel 12. When it is needed to spray oil through the spray pipe 11, the threaded cover 31 is unscrewed, and lubricating oil is poured into the storage barrel 12. When the lubricating oil in the storage barrel 12 is relatively viscous and difficult to flow in the spray pipe 11 by gravity alone, the threaded cover 31 is screwed and then the pressing rod 33 is pressed downward. At this time, the lubricating oil is extruded by the pressing plate 32 and sprayed out of the spray pipe 11, so as to adapt to more types of lubricating oil. In other feasible embodiments, the threaded cover 31 is integrally formed with the storage barrel 12, that is, the threaded cover 31 cannot be detached from the storage barrel 12. A feeding port is formed in the top of the storage barrel 12, and the feeding port is used to add lubricating oil during feeding. However, it is inconvenient to clean the inner wall of the storage barrel 12.

[0035] With reference to Figure 2 , the bottom of the gate bridge 61 is fixedly connected with the feeding cylinder 4, the nozzle of the spray pipe 11 is communicated with an elastic nozzle 111, and the elastic nozzle 111 is in a converging shape and extends into the feeding cylinder 4. When the lubricating oil in the storage barrel 12 is relatively dilute, the converging elastic nozzle 111 has a small diameter, so that the flow of the lubricating oil is small and the waste of the lubricating oil is reduced. When the lubricating oil in the storage barrel 12 is relatively viscous, the pressure of the pressing plate 32 causes the diameter of the elastic nozzle 111 to be expanded, so that the lubricating oil is smoothly sprayed out of the elastic nozzle 111. The lubricating oil is extruded and fills the space between the feeding cylinder 4 and the screw rod 63, so that the screw rod 63 is uniformly and comprehensively coated with the lubricating oil, thereby improving the lubrication and rust prevention effects of the screw rod 63 and reducing the risk of the screw rod 63 caused by rust and other phenomena.

[0036] With reference to Figure 2 and Figure 3 , the scraping assembly 2 includes a rotating ring 21 rotatably connected to the bottom of the feeding cylinder 4 and a scraper 22 hingedly connected to the bottom of the rotating ring 21. The scraper 22 is matched with the threaded part of the screw rod 63, and the scraper 22 is made of hard plastic, which will not rust like iron scraper 22 and will not damage the screw rod 63. The rotating ring 21 is provided with a first elastic member 212 for driving the scraper 22 to rotate towards the screw rod 63. The first elastic member 212 can be a torsion spring. The feeding cylinder 4 is provided with a limiting assembly 5 for limiting the rotation of the rotating ring 21. The limiting assembly 5 includes a pawl 51 arranged on the bottom wall of the feeding cylinder 4, a tooth portion 52 arranged on the peripheral wall of the rotating ring 21 and matched with the pawl 51, and a second elastic member 53 arranged on the feeding cylinder 4 for driving the pawl 51 to abut against the tooth portion 52. The second elastic member 53 is also a torsion spring.

[0037] When the screw rod 63 rises, the rotating ring 21 and the scraper 22 on the rotating ring 21 rotate, so that the scraper 22 scrapes off the sundries on the screw rod 63; when the screw rod 63 descends, the pawl 51 abuts against the straight surface of the tooth portion 52, so that the rotating ring 21 cannot rotate, that is, the scraper 22 cannot rotate, effectively reducing the surface area of the screw rod 63 scraped by the scraper 22, and further reducing the quality of the new lubricating oil hung on the screw rod 63 by the scraper 22.

[0038] The implementation principle of the reservoir gate screw rod jamming risk prevention and control device is as follows: when it is necessary to apply lubricating oil to the screw rod 63, the threaded cover 31 is unscrewed, lubricating oil is poured into the storage barrel 12, when the poured lubricating oil is relatively viscous, the threaded cover 31 is screwed, the pressing rod 33 is pressed downward, the lubricating oil is sprayed from the elastic nozzle 111, the lubricating oil is extruded to fill the space between the feeding cylinder 4 and the screw rod 63, the machine body 62 is opened, and the screw rod 63 rises. At this time, the screw rod 63 drives the scraper 22 to rotate, so that the scraper 22 scrapes off the sundries on the screw rod 63, part of the scraped screw rod 63 enters the feeding cylinder 4 and fully contacts with the lubricating oil, and then the screw rod 63 continues to rise to lubricate the spiral disc mother. When the surface of the screw rod 63 is coated with lubricating oil, the screw rod 63 is lowered, the pawl 51 abuts against the straight surface of the tooth portion 52, so that the scraper 22 cannot rotate, effectively reducing the surface area of the screw rod 63 scraped by the scraper 22.

[0039] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
