Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope lubrication, in particular to a lubrication device for a pitching steel wire rope of a shore container crane. Background Art

[0002] At present, shore container cranes are commonly used lifting machinery in container terminals. The luffing mechanism, lifting mechanism and trolley mechanism of shore container cranes are all pulled and operated by luffing wire ropes. In order to ensure the service life, safety and reliability of the wire ropes, terminal maintenance personnel are required to regularly lubricate and maintain the wire ropes wound on the shore container cranes.

[0003] At present, during the lubrication and maintenance of wire ropes, dock maintenance personnel directly apply grease to the surface of the wire rope using a brush holder with a telescopic rod. Although this traditional lubrication method can play a role in wire rope lubrication and maintenance, it still has the following shortcomings in actual operation:

[0004] 1. The above-mentioned traditional lubrication method is not only inefficient and labor-intensive, but also suffers from uneven oil application and insufficient lubrication. Furthermore, due to the limitations of the wire rope layout and the length of the telescopic rod, there is also a problem in the middle of the wire rope that cannot be lubricated, which makes this section prone to corrosion.

[0005] 2. The potential conflict between the surrounding complex steel structures and the location where personnel are operating increases the safety risk for terminal maintenance personnel.

[0006] 3. The lubricant used needs to have good adhesion and permeability. Fluid grease is often used as a lubricant. However, when using a telescopic rod for coating, the fluid grease is prone to dripping or spilling, especially when lubricating the middle of the wire rope, causing unnecessary pollution to the dock environment and equipment. Utility Model Content

[0007] The purpose of the utility model is to overcome the shortcomings of the prior art such as insufficient lubrication effect, poor safety and environmental pollution, and to provide a shore container crane luffing wire rope lubrication device, which has a reasonable design, simple structure, is easy to use, has good lubrication effect and is safe and reliable. It can not only effectively improve work efficiency, but also reduce environmental pollution, and is suitable for promotion.

[0008] The utility model is realized through the following technical scheme: a lubricating device for the pitching wire rope of a shore container crane comprises a main body bracket, a lubricating sleeve capable of passing the wire rope is arranged on the top side of the main body bracket, an oil filling hole is opened on the lubricating sleeve, two ends of the main body bracket are respectively provided with walking mechanisms arranged on both sides of the lubricating sleeve, and an oil supply mechanism is provided on the bottom side of the main body bracket; the oil supply mechanism is connected with an oil pipe, the oil pipe is connected with the oil filling hole on the lubricating sleeve, and the oil supply mechanism can transport grease to the inner cavity of the lubricating sleeve through the oil pipe and the oil filling hole.

[0009] A further improvement of the present invention is that the lubricating sleeve includes two semicircular sleeves, which are spliced ​​together to form a complete lubricating sleeve, and the two semicircular sleeves are connected as one in a detachable manner and fixed to the top side of the main bracket.

[0010] A further improvement of the present invention is that the inner side wall of the semicircular sleeve is provided with a plurality of semi-annular oil grooves arranged in an array. When the two semicircular sleeves are spliced ​​together, the semi-annular oil grooves on the two semicircular sleeves can be spliced ​​into a complete annular oil groove.

[0011] A further improvement of the present invention is that skeleton oil seals are provided at both ends of the lubricating sleeve.

[0012] A further improvement of the present invention is that the walking mechanism includes a walking wheel and a walking bracket, the walking wheel is installed on the top of the walking bracket, the walking bracket is installed on the main bracket, the walking wheel is located on the top side of the wire rope, and an annular rope groove is provided on the outer circumferential surface of the walking wheel.

[0013] A further improvement of the present invention is that the highest point of the inner cavity of the lubricating sleeve is higher than the lowest point of the bottom of the annular rope groove provided on the traveling wheel.

[0014] A further improvement of the present utility model is that the oil supply mechanism adopts an electric oil dispenser, and the power supply of the electric oil dispenser is installed on the main body bracket.

[0015] From the above technical solutions, it can be seen that the beneficial effects of the present invention are as follows: the device is reasonably designed and simple in structure. It can be directly hung on the pitch wire rope and automatically moves under the action of its own weight without being affected by the surrounding complex steel structure, which greatly improves the lubrication effect of the wire rope. At the same time, the lubrication sleeve can also effectively seal the liquid grease, reducing the dripping of liquid grease, thereby reducing the pollution of the lubrication operation to the terminal site equipment and the environment.

[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0021] Please refer to the attached Figure 1 and 2 , combined with a specific embodiment, it is explained as follows: The utility model is a shore container crane pitching wire rope lubrication device, comprising a main body bracket 1, the top side of the main body bracket 1 is provided with a lubricating sleeve 2 capable of passing a wire rope 7, and the lubricating sleeve 2 is provided with an oil filling hole 202; both ends of the main body bracket 1 are respectively provided with walking mechanisms arranged on both sides of the lubricating sleeve 2, and the walking mechanisms can walk along the wire rope 7, thereby driving the main body bracket 1 to walk on the wire rope 7; the bottom side of the main body bracket 1 is provided with an oil supply mechanism 5, the oil supply mechanism 5 is connected to an oil pipe 6, and the oil pipe 6 is connected to the oil filling hole 202 on the lubricating sleeve 2, and the oil supply mechanism 5 can transport grease to the inner cavity of the lubricating sleeve 2 through the oil pipe 6 and the oil filling hole 202.

[0022] Specifically, the lubricating sleeve 2 includes two semicircular sleeves 201, which are spliced ​​together to form a complete lubricating sleeve 2, and the two semicircular sleeves 201 are detachably connected as a whole by fasteners such as screws, and the lubricating sleeve 2 is fixed to the top side of the main bracket 1 by fasteners such as bolts.

[0023] Specifically, the inner wall of the semicircular sleeve 201 is provided with a plurality of semi-annular oil grooves 203 arranged in an array. When two semicircular sleeves 201 are joined, the semi-annular oil grooves 203 on the two semicircular sleeves 201 can be joined to form a complete annular oil groove. This annular oil groove design not only increases the surface area of ​​the inner wall, thereby increasing the contact area between the inner surface of the annular oil groove and the outer surface of the wire rope 7, but also has a certain function of storing liquid grease. During lubrication operations, it can ensure that the inner cavity of the lubricating sleeve 2 contains sufficient grease, thereby improving the lubrication effect of the wire rope 7. At the same time, the annular oil groove design further improves the effect of "preventing grease from falling."

[0024] Specifically, the traveling mechanism includes a traveling wheel 3 and a traveling bracket 4. The traveling wheel 3 is mounted on the top of the traveling bracket 4, which is mounted on the main frame 1. The traveling wheel 3 is located on the top side of the wire rope 7, and an annular rope groove 301 is formed on the outer circumferential surface of the traveling wheel 3. The device is hung on the wire rope 7 through the traveling mechanism, that is, the traveling wheel 3 presses the wire rope 7 and is clamped on the wire rope 7 through the annular rope groove 301. The wire rope 7 passes through the traveling bracket 4 and the lubricating sleeve 2. Then, the device can automatically move along the inclined wire rope 7 under its own weight to achieve lubrication of the wire rope 7.

[0025] Specifically, the oil supply mechanism 5 utilizes an electric fuel dispenser, and its power supply is mounted on the main frame 1. The specific structure of the electric fuel dispenser and power supply can be referenced in the prior art. The inclusion of a power supply significantly enhances the device's convenience, preventing interference from electrical wiring during long-distance lubrication operations. The power supply can also utilize a lightweight lithium battery. It should be noted that the electric fuel dispenser utilizes intermittent oil injection during actual operation, preventing oil leakage from the lubricating sleeve 2 due to continuous oiling.

[0026] The operating principle of this utility model is as follows: When lubrication of the wire rope 7 is required, the device is first hung on the upper end of the wire rope 7 via the traveling mechanism and the wire rope 7 is passed through the lubricating sleeve 2. After installation, the oil supply mechanism is pre-filled with oil to ensure that the lubricating sleeve 2 is sufficiently filled with liquid grease. At this point, under the action of gravity, the traveling mechanism can slide downward along the inclined direction of the wire rope 7, thereby driving the device to move along the wire rope 7. During this process, the liquid grease in the lubricating sleeve 2 lubricates the wire rope 7. During the entire lubrication process, because the device is directly suspended from the wire rope 7 and moves automatically under its own weight, it is not affected by the surrounding complex steel structure. The lubricating sleeve 2 also forms a "wrapped" structure around the wire rope 7, greatly improving the lubrication effect of the wire rope 7. Furthermore, the lubricating sleeve 2 effectively seals the liquid grease, reducing dripping of the liquid grease and, in turn, reducing contamination to the terminal's on-site equipment and environment caused by the lubrication operation.

[0027] In one embodiment, skeleton oil seals are provided at both ends of the lubricating sleeve 2. The skeleton oil seals can further improve the sealing performance of the lubricating sleeve 2, thereby ensuring that the liquid grease in the lubricating sleeve 2 can be evenly applied to the steel wire rope 7.

[0028] In one embodiment, the highest point of the lubricating sleeve 2's inner cavity is higher than the lowest point of the bottom of the annular rope groove 301 provided in the running wheel 3. This design not only ensures that the wire rope 7 can roll in contact with the running wheel 3, reducing friction between the device and the wire rope 7, but also ensures that the wire rope 7 passes smoothly through the lubricating sleeve 2, thereby more conducive to the wire rope 7 coming into contact with the liquid grease in the lubricating sleeve 2, thereby achieving lubrication of the wire rope 7.

[0029] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
