Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ship lift steel rope maintenance technology, and specifically relates to an online lubrication device for the steel wire rope of a fully balanced ship lift fixed pulley. Background Technology
[0002] The counterweight system in a fully balanced ship lift consists of multiple counterweight blocks. These blocks are connected to the ship-bearing compartment via steel wire ropes that pass over a fixed pulley system. The total weight of the counterweight blocks is roughly the same as the weight of the ship-bearing compartment (including the ship and water). Driving the ship-bearing compartment up and down only requires overcoming a small amount of resistance such as unbalanced loads and friction. The steel wire ropes are always under tension, and friction occurs between the wire rope and the grooves of the fixed pulleys during operation. Over time, the wire ropes will wear down, necessitating lubrication to extend their service life. Currently, lubrication of the steel wire ropes in fully balanced ship lifts is primarily done manually by applying oil or using lubrication devices. This process is time-consuming and labor-intensive, with poor lubrication results, and can affect the normal operation of the ship lift. Furthermore, because the wire ropes are always under tension, the gaps between the strands are small, preventing surface-applied lubricating oil from penetrating the core, resulting in ineffective lubrication. Utility Model Content

This device solves the problem that existing technologies cannot maintain the internal structure of the wire rope and require regular manual maintenance, thus wasting human resources.
[0004] This utility model is achieved through the following solution:
[0005] An online lubrication device for the wire rope of a fixed pulley in a fully balanced ship lift includes a first lubrication component, a second lubrication component, and an oil storage component. Both the first and second lubrication components are connected to the oil storage component. The oil outlet of the first lubrication component is located at the point where the wire rope of the fixed pulley to be lubricated has the greatest curvature. The oil outlet of the second lubrication component is located at at least one side of the rope groove at the bottom of the fixed pulley.
[0006] Based on the structure of the above-mentioned online lubrication device for the wire rope of the fixed pulley of a fully balanced ship lift, the fixed pulley to be lubricated includes a bearing housing, a fixed pulley, and a rotating shaft. The bearing housing is provided with a connecting groove that mates with the rotating shaft. The rotating shaft is movably disposed in the connecting grooves at both ends of the bearing housing. Multiple partition plates are provided in the bearing housing, dividing the bearing housing into multiple accommodating cavities. The center of the fixed pulley passes through the rotating shaft and is disposed in the accommodating cavity. Wire rope grooves are symmetrically arranged on the fixed pulley.
[0007] Based on the structure of the above-mentioned online lubrication device for the wire rope of the fixed pulley of a fully balanced ship lift, the first lubrication component includes a drip oil inlet pipe, a drip oil return pipe, and a drip can; the drip oil inlet pipe and the drip oil return pipe are respectively connected to the oil storage component to form a first lubrication circuit, and multiple drip cans are set in the first lubrication circuit; the position of the drip can is matched with the position of the steel rope groove.
[0008] Based on the structure of the above-mentioned online lubrication device for the wire rope of the fixed pulley of a fully balanced ship lift, the drip irrigation inlet pipe and the drip irrigation return pipe are rigid structures, or the drip irrigation inlet pipe and the drip irrigation return pipe are supported by a support structure so that the drip irrigation head is located at the position where the bending curvature of the wire rope at the top of the fixed pulley is the maximum.
[0009] Based on the structure of the above-mentioned online lubrication device for the fixed pulley wire rope of a fully balanced ship lift, the drip can is also equipped with a drip irrigation flow control valve with heating function.
[0010] Based on the structure of the above-mentioned online lubrication device for the wire rope of the fixed pulley of a fully balanced ship lift, the second lubrication component includes an oil inlet pipe, an oil return pipe, and an oil lubrication head; the oil inlet pipe and the oil return pipe are respectively connected to the oil storage component to form a second lubrication circuit; multiple oil lubrication heads are set along the length of the second lubrication circuit, and the positions of the oil lubrication heads are matched with the positions of the wire rope grooves, and the oil lubrication heads are embedded in the wire rope grooves.
[0011] Based on the structure of the above-mentioned online lubrication device for the fixed pulley wire rope of a fully balanced ship lift, a flow control valve for applying the lubricant is provided on the pipeline connecting the second lubrication circuit and the lubrication head.
[0012] Based on the structure of the above-mentioned online lubrication device for the fixed pulley wire rope of a fully balanced ship lift, the oil storage assembly is equipped with a delivery pump, a heating device, and a stirring device; the delivery pump is used to deliver the oil in the oil storage assembly to the first lubrication circuit and the second lubrication circuit respectively, the heating device is used to heat the lubricating oil, and the stirring device is used to stir the oil in the oil storage assembly.
[0013] Based on the structure of the above-mentioned online lubrication device for the fixed pulley wire rope of a fully balanced ship lift, two second lubrication circuits are symmetrically arranged at the bottom of the bearing housing. Each second lubrication circuit is connected to the oil storage component, and each second lubrication circuit is equipped with a lubrication head for lubricating the wire rope groove.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0016] 1. When the wire rope is bent at its maximum angle, the gap between the strands is at its maximum. By using the first lubrication component to apply lubricating oil at the point of maximum bending angle, the lubricating oil can effectively penetrate into the wire rope, extending its service life. Simultaneously, the main contact points between the wire rope and the pulley are the wire rope surface and the pulley groove. By using the second lubrication component to spray lubricating oil at the groove location, friction between the wire rope and the groove surface can be effectively reduced, extending the service life of both the wire rope and the pulley. This dual lubrication of the wire rope surface and interior achieves efficient wire rope maintenance.
[0017] 2. The bottom lubrication device in this solution can reduce wear between the wire rope and the groove of the fixed pulley by lubricating the groove, thus extending the service life of the wire rope and the groove. In addition, the lubrication position is relatively fixed, and the lubrication will not affect the normal operation of the wire rope and the fixed pulley. Therefore, it can be operated when the ship lift equipment is working normally.
[0018] 3. The lubricating oil pumping device in this solution is equipped with a heater and a stirring device, which can adjust the temperature of the lubricating oil and the uniformity of solute and solvent in the lubricating oil, so that the lubricating oil is in the best condition and the lubrication effect is better.
[0019] 4. The drip flow control valve with heating function in the top drip irrigation device of this solution has been added with heating function, which can adjust the temperature of the dripping lubricating oil, so that the lubricating oil has better permeability and can reach the core of the steel wire rope more easily.

[0029] Example 1
[0030] like Figs. 1-4 As shown, this utility model provides a technical solution:
[0031] An online lubrication device for the wire rope 4 of the fixed pulley 6 of a fully balanced ship lift includes, but is not limited to, a first lubrication component 1, a second lubrication component 2, and an oil storage component 3. The first lubrication component 1 and the second lubrication component 2 are both connected to the oil storage component 3. The oil outlet of the first lubrication component 1 is located at the point where the curvature of the wire rope 4 of the fixed pulley 6 to be lubricated is the maximum. The oil outlet of the second lubrication component 2 is located at at least one side of the rope groove at the bottom of the fixed pulley 6.
[0032] Based on the above structure, when the bending angle of the wire rope 4 is at its maximum, the gap between the strands in the wire rope 4 is at its maximum. By using the first lubrication component 1 to drip lubricating oil at the position where the bending angle of the wire rope 4 is at its maximum, the lubricating oil can effectively enter the interior of the wire rope 4, extending the service life of the wire rope 4. At the same time, the main contact parts between the wire rope 4 and the fixed pulley 6 are the surface of the wire rope 4 and the groove of the fixed pulley 6. By using the second lubrication component 2 to spray lubricating oil at the groove position, the friction between the wire rope 4 and the groove surface can be effectively reduced, extending the service life of the wire rope 4 and the fixed pulley 6. Through dual lubrication of the surface and interior of the wire rope 4, efficient maintenance of the wire rope 4 can be achieved.
[0033] As an example, the fixed pulley 6 to be lubricated may include a bearing housing 5, a fixed pulley 6, and a rotating shaft 7. The bearing housing 5 is provided with a connecting groove 8 that mates with the rotating shaft 7. The rotating shaft 7 is movably disposed in the connecting grooves 8 at both ends of the bearing housing 5. Multiple partition plates 9 are provided in the bearing housing 5, which divide the bearing housing 5 into multiple accommodating cavities. The center of the fixed pulley 6 passes through the rotating shaft 7 and is disposed in an accommodating cavity. Steel rope grooves 10 are symmetrically arranged on the fixed pulley 6.
[0034] Based on the above structure, multiple fixed pulleys 6 can be supported simultaneously by the bearing seat 5, and multiple fixed pulleys 6 can transmit power to multiple sets of wire ropes 4, thus achieving efficient transmission.
[0035] As an example, the first lubrication component 1 may include a drip inlet pipe 101, a drip return pipe 102, and a drip can 103; the drip inlet pipe 101 and the drip return pipe 102 are respectively connected to the oil storage component 3 to form a first lubrication circuit, and multiple drip cans 103 are set in the first lubrication circuit; the position of the drip can 103 is matched with the position of the steel rope groove 10.
[0036] Based on the above structure, the lubricating oil is transported through the drip oil inlet pipe 101 and the drip oil return pipe 102, and finally the lubricating oil is dripped into the outer surface of the steel wire rope 4 in the steel rope groove 10 through the drip head.
[0037] As an example, the drip irrigation inlet pipe 101 and the drip irrigation return pipe 102 are rigid structures, or the drip irrigation inlet pipe 101 and the drip irrigation return pipe 102 are supported by a support structure so that the drip irrigation head is located at the position where the bending curvature of the steel wire rope 4 at the top of the fixed pulley 6 is the maximum.
[0038] Based on the above structure, the drip head is specially positioned so that the steel rope located at the point of maximum curvature can be lubricated by the lubricating oil, thus maximizing the lubrication effect.
[0039] As an example, a drip irrigation flow control valve 104 with a heating function can also be set in the drip can 103; the drip irrigation flow control valve 104 with a heating function can more accurately control the lubricating oil of the wire rope 4, and the heating makes the whole drip irrigation process smoother.
[0040] As an example, the second lubrication assembly 2 may include an oil inlet pipe 201, an oil return pipe 202, and an oil lubrication head 203; the oil inlet pipe 201 and the oil return pipe 202 are respectively connected to the oil storage assembly 3 to form a second lubrication circuit; multiple oil lubrication heads 203 are provided along the length direction of the second lubrication circuit, the positions of the oil lubrication heads 203 are matched with the positions of the steel rope groove 10, and the oil lubrication heads 203 are embedded in the steel rope groove 10.
[0041] Based on the above structure, lubricating oil is transported through the oil inlet pipe 201 and the oil return pipe 202, and finally the lubricating oil is applied to the steel rope groove 10 through the lubrication head 203 to achieve the lubrication operation of the inner surface of the steel wire rope 4.
[0042] As an example, a coating flow control valve 204 is installed on the pipeline connected to the coating lubrication head 203 in the second lubrication circuit. By controlling the coating flow, the amount of moisturizing oil injected can be precisely controlled, and the coating can be automated without manual operation.
[0043] As an example, the oil storage assembly 3 is equipped with a delivery pump, a heating device 301, and a stirring device 302. The delivery pump is used to deliver the oil in the oil storage assembly 3 to the first lubrication circuit and the second lubrication circuit respectively, providing power for the dripping and application. The heating device 301 is used to heat the lubricating oil and reduce the delivery resistance. The stirring device 302 is used to stir the oil in the oil storage assembly 3 to make the oil temperature more uniform.
[0044] As an example, two second lubrication circuits can be symmetrically arranged at the bottom of the bearing housing 5. Each second lubrication circuit is connected to the oil storage component 3, and each second lubrication circuit is provided with a lubrication head 203 for lubricating the steel rope groove 10.
[0045] Based on the above structure, by setting lubrication heads 203 on both sides of the bearing housing 5, lubricating oil can be applied to the steel rope groove 10 when the fixed pulley 6 rotates forward or backward, making the lubrication of the entire steel rope more comprehensive.
[0046] As an example, each bearing housing 5 is provided with 4 fixed pulleys 6, each fixed pulley 6 is provided with 2 steel rope grooves 10, and there are 8 lubrication heads 203 and 8 drip irrigation heads.

[0048] like Figs. 1-4 As shown, this utility model provides a technical solution:

[0050] Step 1: When lubrication is detected as needed, the delivery pump in the oil storage assembly 3 is turned on. The heating device 301 and the stirring device 302 are turned on according to the ambient temperature, so that the entire lubricating oil body flows in the first lubrication return and second lubrication circuits.
[0051] Step 2: Select and open the drip head on the first lubrication return circuit and / or the lubrication application head 203 on the second lubrication circuit according to the degree of lubrication required for the steel rope, so that the drip head drips at the top of the fixed pulley 6 and applies lubricating oil at the bottom of the fixed pulley 6.
[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
