Description

Technical Field

[0001] The utility model belongs to the technical field of lubrication devices, and particularly relates to a wire rope lubrication device for a crawler crane. Background Art

[0002] The wire ropes used in crawler cranes are high-strength alloy wire ropes; this kind of wire rope has the characteristics of wear resistance, tensile resistance and corrosion resistance, and is suitable for lifting and hoisting operations; its main materials include alloy steel and galvanized treatment, as well as fiber rope cores or metal rope cores; alloy steel is added with a certain proportion of alloying elements (such as chromium, nickel, molybdenum, etc.) to improve the strength, hardness and corrosion resistance of the steel, so that the wire rope has high strength and durability, and is suitable for heavy lifting and hoisting operations; galvanized treatment can effectively prevent the wire rope from rusting and corroding in humid and corrosive environments, extend the service life and improve safety. The core part of the wire rope usually uses a fiber rope core or a metal rope core. The fiber rope core is mainly composed of synthetic fibers or natural fibers, and has the advantages of softness and light weight, but is easily damaged in high-temperature and humid environments; the metal rope core is woven from steel wires and has higher strength and durability, and is suitable for heavy-load and high-strength hoisting operations; the wire rope needs to be lubricated with oil during use, and thus a lubrication device is required; in the prior art, when lubricating the wire rope, it is usually necessary to manually apply lubricating oil to the wire rope. The manual application speed is slow, the effect is poor, and at the same time, the labor intensity of the operator is increased and the work efficiency is reduced. Summary of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a wire rope lubrication device for a crawler crane, which effectively solves the problems that in the prior art, when lubricating the wire rope, it is usually necessary to manually apply lubricating oil to the wire rope, and the manual application speed is slow and the effect is poor.

[0004] To achieve the above object, the present utility model provides the following technical solution: A wire rope lubricating device for a crawler crane, comprising a device main body. Through holes for the rope are provided in the middle of the upper and lower sides of the device main body. Oil application rollers are provided on both sides inside the device main body. First oil-absorbing cotton is fixedly installed on the surfaces of the two oil application rollers. Rotating shaft rods are fixedly installed in the middle of the two oil application rollers. Positioning shaft seats are rotatably installed at both ends of the two rotating shaft rods. Positioning strips are fixedly installed at the ends of the positioning shaft seats away from the rotating shaft rods. Fixed support blocks are fixedly installed at the tops of the four positioning strips, and the four fixed support blocks are respectively fixedly installed on both sides of the device main body. Pushing blocks are fixedly installed on both sides of the two oil application rollers. Oil storage cavities are provided inside both sides of the device main body. Oil injection nozzles are fixedly installed between the tops of the two oil storage cavities and both sides of the top of the device main body. A self-lubricating component is provided between the two oil storage cavities and the inside of the device main body.

[0005] Preferably, the self-lubricating component includes two rectangular limiting sliding sleeves and two placement grooves. The two rectangular limiting sliding sleeves are fixedly installed in the middle of the inner walls on both sides of the device main body. Rectangular limiting sliding rods are inserted into the two rectangular limiting sliding sleeves. The two placement grooves are provided on the inner walls of the two oil storage cavities close to each other. One end of the two rectangular limiting sliding rods away from each other extends into the placement grooves and fixedly installs sealing plates.

[0006] Preferably, sealing gaskets are fixedly installed on the sides of the two sealing plates close to the placement grooves to increase the sealing performance between the placement grooves and the sealing plates.

[0007] Preferably, arc-shaped moving plates are fixedly installed at the ends of the two rectangular limiting sliding rods close to each other. Second oil-absorbing cotton is fixedly installed on the sides of the two arc-shaped moving plates close to each other. The two second oil-absorbing cotton are in contact with the two first oil-absorbing cotton.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: During installation, the operator fixedly installs the device body on the crawler crane and passes the steel wire rope through the two oiling rollers. Before use, the operator first injects lubricating oil into the interiors of the two oil storage cavities through the two oil injection nozzles. During use, when the steel wire rope moves, it drives the two oiling rollers to rotate through friction. When the two oiling rollers rotate, they both drive the two rotating shaft rods to rotate along the positioning shaft seats. While the two oiling rollers are rotating, they both intermittently drive the pushing blocks to push the two arc-shaped moving plates. When the arc-shaped moving plates are pushed, they both drive the rectangular limiting sliding rods to move along the rectangular limiting sliding sleeves into the interiors of the oil storage cavities and simultaneously compress the springs. The springs play a role in driving the rectangular limiting sliding rods to reset;

[0010] When the two rectangular limiting sliding rods move into the interiors of the oil storage cavities, they both drive the sealing plate away from the placement groove, thereby exposing the oil inlet holes, enabling the lubricating oil inside the oil storage cavity to enter the interior of the oil passing groove through the oil inlet holes and enter the second oil-absorbing cotton through the oil passing groove. When the two oiling rollers rotate, they drive the two first oil-absorbing cottons to contact the two second oil-absorbing cottons, thereby sucking the lubricating oil in the two second oil-absorbing cottons into the two first oil-absorbing cottons and continuously applying the lubricating oil to the surface of the steel wire rope through the two first oil-absorbing cottons; enabling this lubrication device to achieve self-lubrication of the steel wire rope without manual application, thereby reducing the labor intensity of the operator and improving work efficiency.

[0021] During installation, the operator fixedly installs the device main body 1 on the crawler crane and passes the steel wire rope through the two oil coating rollers 3; before use, the operator first injects lubricating oil into the two oil storage cavities 8 through the two oil injection nozzles 9. During use, when the steel wire rope moves, it will drive the two oil coating rollers 3 to rotate through friction. When the two oil coating rollers 3 rotate, they both drive the two rotating shaft rods 5 to rotate along the positioning shaft seats 6. While the two oil coating rollers 3 rotate, they will intermittently drive the pushing blocks 19 to push the self-lubricating component to operate.
