Description

Technical Field

[0001] This utility model relates to the field of hydraulic gate maintenance technology, and in particular to a maintenance device for a winch-type hydraulic gate opening and closing machine. Background Technology

[0002] The winch-type hydraulic gate hoisting and maintenance device is a core piece of equipment used in water conservancy projects to control the raising and lowering of gates. It mainly uses steel cables or steel cable pulley blocks as lifting devices to connect the gates, and uses a gear transmission system to drive the winch drum to raise and lower the steel cables, thereby driving the gates to rise and fall.

[0003] In the long-term operation of winch-type gate hoists, the wire rope, as a core load-bearing component, is directly affected by lubrication and maintenance, impacting the equipment's service life and operational safety. Currently, there are two main solutions for wire rope lubrication: one is manual high-altitude oiling, requiring operators to climb to the hoist position to manually apply the oil, which is not only labor-intensive and risky but also results in poor oil uniformity; the other is automatic oiling devices, which mostly adopt a closed integrated structure. However, the main body of the equipment needs to be disassembled when installing the wire rope, making installation and maintenance cumbersome. Furthermore, there is a lack of targeted heating mechanisms, and in low-temperature winter environments, the viscosity of the lubricating grease increases, and its fluidity decreases. Even if the equipment can perform the oiling action, the grease cannot effectively wet the wire rope.

[0004] Based on the above situation, we propose a maintenance device for a winch-type hydraulic gate opening and closing machine to solve the above problems. Utility Model Content

[0005] This utility model provides a maintenance device for a winch-type hydraulic gate opening and closing machine to solve the problems existing in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution: A maintenance device for a winch-type hydraulic gate hoist includes a winch body. A maintenance box for maintaining the wire rope is provided along the wire rope's running direction on the winch body. An oil-collecting box for holding a lubricating medium is provided inside the maintenance box. A heating element for heating the lubricating medium is provided at the bottom of the oil-collecting box. An oil-immersing roller is rotatably connected to the upper end of the oil-collecting box via a connecting rod, pressing the wire rope down into the lubricating medium in the oil-collecting box, ensuring full contact and immersion of the wire rope with the lubricating medium during operation. Oil-distributing components are provided at both ends of the oil-collecting box. Each oil-distributing component includes two sets of opposing pressing rollers, with a channel formed between the two sets of pressing rollers for the wire rope to pass through.

[0007] Preferably, the upper end of the maintenance box is hinged to a cover plate, and a locking element is provided between the cover plate and the maintenance box.

[0008] Preferably, the inner bottom wall of the oil container and the bottom of the cover plate are provided with elastic connectors, the movable end of the elastic connector is connected to a connecting shaft, and the extrusion wheel is rotatably connected to the connecting shaft.

[0009] Preferably, the elastic connector includes a fixed sleeve and a sliding rod slidably connected inside the fixed sleeve, and a spring is provided between the fixed sleeve and the sliding rod.

[0010] Preferably, the maintenance box has slots at both ends for steel wire ropes to pass through, and a scraper is provided on the inner wall of the slots.

[0011] Preferably, the winch body is provided with a rope guide on the side near the winch drum for guiding the orderly winding of the wire rope, and the maintenance box is connected to the rope guide.

[0012] The beneficial effects of this utility model are as follows: by setting a maintenance box in the running path of the wire rope of the winch, the oil box is used to hold the lubricating medium, the bottom heating element heats the lubricating medium, the low temperature reduces viscosity and ensures fluidity, and the oil-immersing pressure roller presses down the wire rope to achieve full oil immersion, ensuring the lubrication effect. At the same time, the upper and lower sets of extrusion rollers at both ends of the oil box can clamp the wire rope, so that the lubricating medium can penetrate into the gap of the wire rope.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0017] Reference Figures 1-4 As shown, a maintenance device for a winch-type hydraulic gate hoist includes a winch body 1, a maintenance box 2 for maintaining the wire rope in the direction of wire rope travel of the winch body 1, an oil container 21 containing lithium-based grease or other types of lubricating media inside the maintenance box 2, and a heating element 3 for heating the lubricating media at the bottom of the oil container 21. The heating element 3 can be a stainless steel electric heating tube, etc., and is connected to a manual switch and temperature adjustment knob on the outside of the maintenance box 2 via wires. The temperature adjustment range is limited to 30-50℃, and the start and stop can be manually controlled according to the ambient temperature to ensure that the viscosity of the grease is reduced in low-temperature environments, maintaining good fluidity for better adhesion to the wire rope. The upper end is rotatably connected to an oil-immersed pressure roller 4 via a connecting rod, which presses the wire rope down into the lubricating medium in the oil-collecting box 21. The oil-immersed pressure roller 4 has an arc-shaped groove in the middle of its wheel surface that matches the diameter of the wire rope. The wire rope is located at the bottom of the arc-shaped groove, so that the wire rope is fully in contact with and wetted by the lubricating medium during operation. The oil-collecting box 21 has oil-distributing components 5 at both ends. The oil-distributing components 5 include two sets of opposing extrusion rollers 51, and the two sets of extrusion rollers 51 form a channel 52 for the wire rope to pass through. The center line of the channel 52 is consistent with the center line of the arc-shaped groove of the oil-immersed pressure roller 4 in the middle of the oil-collecting box 21, ensuring that the wire rope can pass through the oil-distributing components 5 and the oil-immersed pressure roller 4 in a straight line. This can play a role in straightening and limiting the wire rope, and prevent deviation during operation.

[0018] Reference Figure 2As shown, furthermore, a cover plate 22 is hinged to the upper end of the maintenance box 2. A locking member 23 is provided between the cover plate 22 and the oil collection box 21. Lubricating grease can be easily added by opening the cover plate 22. The locking member 23 can be used with bolts or other means to securely connect the cover plate 22 to the oil collection box 21. Elastic connectors 53 are provided on the inner bottom wall of the oil collection box 21 and the bottom of the cover plate 22. A connecting shaft 54 ​​is connected to the movable end of the elastic connector 53. The extrusion roller 51 is rotatably connected to the connecting shaft 54. (The last sentence is a repetition of the first paragraph and can be omitted.) The connection, the elastic connector 53 includes a fixed sleeve 531 and a sliding rod 532 that is slidably connected inside the fixed sleeve 531. A spring 533 is provided between the fixed sleeve 531 and the sliding rod 532. After the cover plate 22 is closed, the upper and lower sets of extrusion rollers 51 are arranged opposite each other to form a channel 52 for the wire rope to pass through. Under the elastic force of the spring 533, the extrusion rollers 51 always elastically resist the wire rope, which can not only adapt to the maintenance needs of wire ropes of different diameters, but also ensure that the wire rope is stably in the oil-immersed position. Furthermore, through the flexible extrusion of the wire rope by the extrusion rollers 51, excess grease on the surface is scraped off, while allowing the lubricating grease to penetrate into the gaps of the wire rope to form a uniform oil film.

[0019] The maintenance box 2 has slots 6 at both ends for the wire rope to pass through, and a scraper 61 is provided on the inner wall of the slot 6. The scraper 61 can be made of high molecular weight polyethylene and is used to scrape off impurities such as mud, sand and old grease clumps on the surface when the wire rope enters and exits, so as to reduce the impurities from mixing into the lubricating medium and affecting the lubrication quality.

[0020] Reference Figure 1 As shown, furthermore, the winch body 1 is provided with a rope guide 7 on the side near the winch drum to guide the orderly winding of the wire rope. The curing box 2 is connected to the rope guide 7 to ensure that the curing box 2 is coaxially aligned with the wire rope running trajectory when the winch body 1 is running.
