Description

Technical Field

[0001] The utility model relates to the field of gate maintenance equipment, in particular to a lubrication maintenance device for water gate lifting equipment. Background Art

[0002] The sluice gate is a control facility used to close and open the water discharge (release) channel. It is an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, etc. According to the different lifting mechanisms, the sluice gate is divided into hydraulic cylinder type, winch lifting type and screw lifting type. Among them, the winch lifting type is widely used in different places due to its high lifting weight, adaptability, simple operation and maintenance, and wide application range. The lifting mechanism of the winch is mainly composed of a pulley block, a drum block and a drive device (motor, gear transmission mechanism, reducer, etc.). The motor drives the drum to rotate, and the wire rope on the drum is wound or lowered to realize the lifting and lowering of the gate. Therefore, the wire rope is subjected to a large tensile force during the working process. Long-term stress causes a series of friction, wear and other phenomena inside it. The most important factor affecting its life is that the wire rope is often in contact with water, and corrosion and rust often occur. Therefore, it is necessary to carry out daily maintenance of the wire rope. Lubrication and oiling to prevent rust are one of the important daily maintenance tasks for the wire rope.

[0003] At present, the maintenance of wire ropes is mainly done manually, which is obviously inefficient and unsafe. Another method is an automatic maintenance trolley, such as the patent CN116624746A discloses a hydraulic lifting rope automatic maintenance and patrol trolley. Although it can achieve high-efficiency oiling, it cannot recycle and recycle excess lubricating oil on the wire rope. Unless the manual oiling is applied more evenly, other automatic oiling devices are difficult to control the amount of oiling, and generally there is a problem of excess lubricating oil flowing down the wire rope, which results in more lubricating oil being wasted.

[0032] like Figure 1-5 As shown, a lubrication maintenance device for a sluice lifting device comprises a housing 1, a traveling wheel mechanism 3, a lubricating wheel mechanism 4, an oil receiving chamber 6 and an oil delivery mechanism 8. The housing 1 is provided with a through hole 2 which passes through from top to bottom for the steel wire rope to pass through, the traveling wheel mechanism 3 is arranged in the housing 1, the lubricating wheel mechanism 4 is located below the traveling wheel mechanism 3, the oil receiving chamber 6 is located below the lubricating wheel mechanism 4, the traveling wheel mechanism 3 can clamp the steel wire rope and run on it, thereby driving the entire lubrication maintenance device to run on the steel wire rope. The lubricating wheel mechanism 4 is rotatably arranged in the box body 1. The lubricating wheel mechanism 4 has an oil storage chamber 404 and an oil outlet channel 405. The lubricating wheel mechanism 4 can move along the wire rope driven by the traveling mechanism, and throw the lubricating oil in the oil storage chamber 404 to the wire rope through the oil outlet channel 405, and the oil receiving chamber 6 can recover the excess lubricating oil from the wire rope. The oil delivery mechanism 8 is connected between the oil receiving chamber 6 and the oil storage chamber 404, collects the oil in the oil receiving chamber 6 and delivers it to the oil storage chamber 404 through the oil delivery mechanism 8 for reuse.

[0033] Furthermore, the structure of the above-mentioned oil delivery mechanism 8 specifically includes an oil delivery pipe 801 and an oil pump 802. One end of the oil delivery pipe 801 extends into the oil receiving chamber 6 near the bottom, and the other end is connected to the oil storage chamber 404. When the oil pump 802 is turned on, the lubricating oil in the oil receiving chamber 6 can be pumped 802 into the oil storage chamber 404 for recycling.

[0034] Furthermore, the structure of the above-mentioned walking wheel mechanism 3 includes a first walking wheel 301 and a second walking wheel 302, the first walking wheel 301 and the second walking wheel 302 are rotatably arranged in the box body 1 and one end of the rotating shaft is connected to the driving component arranged in the box body 1, the driving component here can be a motor reducer 305, the rotating shaft is arranged front and back on the box body 1, the first walking wheel 301 and the second walking wheel 302 are respectively provided with a guide groove 303 (similar to the shape of a waist drum wheel) around their circumference, and the surface of the guide groove 303 is paved with a flexible layer 304, the flexible layer 304 can be a silicone layer or a rubber layer, and the flexible layer 304 can be set by gluing or fixing with screws In the guide groove 303, the cross-sectional shape of the guide groove 303 is an arc, and the arc length is less than half of the circumference of the wire rope. The wire rope passes between the guide groove 303 of the first walking wheel 301 and the guide groove 303 of the second walking wheel 302. Since the sum of the arc lengths of the two guide grooves 303 is less than the circumference of the wire rope, the first walking wheel 301 and the second walking wheel 302 can clamp the wire rope. Since the flexible layer 304 is arranged on the surface of the guide groove 303, the friction between the first walking wheel 301, the second walking wheel 302 and the wire rope is increased, thereby avoiding slippage between the walking mechanism and the wire rope, and ensuring that the entire lubrication and maintenance device automatically moves on the wire rope.

[0035] Furthermore, the lubrication wheel mechanism 4 includes two lubrication wheels 401, the rotating shafts of the two lubrication wheels 401 are rotatably connected to the housing 1 through bearings, the two lubrication wheels 401 are located on both sides of the wire rope and are in contact with the wire rope, and each lubrication wheel 401 has an annular groove 403 (similar to the shape of a waist drum wheel) around its outer edge, and an oil-immersed layer 402 is laid on the surface of the annular groove 403, and the oil-immersed layer 402 is preferably cotton cloth, which is wound around the annular groove 403.

When the first running wheel 301 and the second running wheel 302 clamp the steel wire rope and run on the steel wire rope, the two lubricating wheels 401 are driven to run along the steel wire rope. During the running process, the lubricating wheels 401 continuously flow the lubricating oil in the oil storage chamber 404 to the oil immersion layer 402 through the oil outlet channel 405. When the oil immersion layer 402 contacts the steel wire rope and is compressed and deformed, the oil in the oil immersion layer 402 is squeezed out and brushed on the steel wire rope.

[0036] Furthermore, in order to quickly flow the lubricating oil in the oil storage chamber 404 to the oil immersion layer 402 and avoid the situation where a section of the wire rope cannot be coated with lubricating oil, the above-mentioned oil outlet channels 405 are arranged in plurality, and the plurality of oil outlet channels 405 are evenly spaced along the circumference of the lubrication wheel 401.

[0037] Furthermore, the oil storage chamber 404 is annular, and an axial oil passage 804 is provided along the axial direction of the rotating shaft center of each lubrication wheel 401, and a radial oil passage 805 is provided along the radial direction thereof.

The flexible oil scraper ring 7 can be a rubber ring. On the one hand, the flexible oil scraper ring 7 can scrape off excess lubricating oil on the wire rope, and at the same time, it also plays a sealing role to prevent the lubricating oil from continuing to flow down along the wire rope from here, causing the oil receiving chamber 6 to lose its oil receiving function.
