Technical Field

[0001] The utility model belongs to the field of hydrological forecasting, and in particular relates to a pneumatic steel wire rope lubrication device. Background Art

[0002] In the winch-balanced vertical ship lift, the wire rope is an important equipment. The existing wire rope is generally lubricated mainly by manual means, and special grease is applied to the surface of the wire rope, which cannot guarantee the lubrication effect. The operating environment of the ship lift wire rope is very harsh, mainly with high humidity. The wire rope rusts and corrodes frequently and needs to be lubricated in time. Traditional wire rope lubrication methods mostly use manual application or spraying of grease, which has problems such as low efficiency and uneven lubrication. It is also difficult to implement in high-altitude operations or narrow spaces, and it is difficult to meet the efficient and precise maintenance needs of modern industry. For this reason, a pneumatic wire rope lubrication device specifically for wire rope lubrication has been developed, which is urgently needed to improve the lubrication efficiency and quality of the wire rope, reduce manual intervention, and ensure the safety and reliability of equipment operation.

DETAILED DESCRIPTION

[0019] The preferred solution is Figures 1 to 4 As shown in the figure, a pneumatic wire rope lubrication device is composed of a mobile trolley 1, a guide rail 2, a lubricator assembly 3, an oil drum 4, a pneumatic pump 5, a manual reversing valve 6, a filter pressure regulating valve 7, and an external air source plate 8. The function of each component is:

[0020] The mobile trolley 1 can carry the device and move it easily;

[0021] The guide rail 2 is welded with a metal structure and is arranged along the entire length of the area requiring lubrication;

[0022] The lubricator assembly 3 is the core component of the device, which completes the lubrication of the wire rope;

[0023] The oil drum 4 is used to store grease;

[0024] The pneumatic pump 5 provides power for the lubrication assembly;

[0025] There are two manual reversing valves, including the first manual reversing valve 601 and the second manual reversing valve 602, which are two-position three-way manual reversing valves, respectively controlling the pneumatic pump and the cylinder;

[0026] 7 filter pressure regulating valves, used for filtering air particles;

[0027] The external gas source plate 8 is convenient for connecting to the on-site gas source.

[0028] The working principle of this device:

[0029] 1. At the wire rope maintenance platform, a 400mm slot is reserved in the front of the balancing drum and the hoist drum to install the H-shaped steel (HN100*50) that serves as the slide rail. Studs need to be welded on-site to the embedded angle steel at both ends. The slot for the torque rope on the hoist drum is 2300mm wide and requires pre-embedded bolts or on-site welding to the embedded angle steel at both ends.

[0030] 2. The length of the steel section corresponds to the groove length of different drums on the same platform (7.8 meters for the balancing drum and 6 meters for the lifting drum). It is used for roller guidance. A heavy-duty slide platform is installed on the upper part. Each group of drums requires one slide platform. The number of slide platforms is 4*2+8*2*2=40, with 24 short slide platforms and long slide platforms. It can slide to any wire rope along the direction of the wire rope arrangement.

[0031] 3. Install the lubricator assembly on the heavy-duty slide platform, push the slide, and move the lubricator toward the wire rope.

[0032] 4. After the lubricator assembly and the slide platform are in place, the rollers at the front of the slide platform engage the H-beam for upper and lower limit stops. Lubrication begins, and the wire rope moves up or down while also moving left or right, with a total travel of approximately 600 mm. During this time, the wire rope acts on the guide wheel on the lubricator, driving the lubricator and the slide platform to the left or right.

[0033] 5. Move the lubrication trolley to the vicinity of the target wire rope;

[0034] 6. Remove the wire rope lubricator assembly from the trolley, place it on the heavy-duty slide platform on the equipment floor, and fasten it with bolts. Push the slide platform so that the opening of the lubricator assembly faces the wire rope. Once in place, the upper and lower guide wheels clamp the wire rope respectively to guide it.

[0035] 7. Insert the quick connector of the oil pipe of the pneumatic pump grease outlet into the grease inlet of the lubricator assembly. Connect the two lines on the trolley to the pneumatic pump and the opening and closing cylinder of the lubricator assembly respectively. The mobile trolley is equipped with a hose reel for connecting to the on-site air source.

[0036] 8. Coordinate with the central control to start the ship lift, and at the same time open the manual reversing valve that controls the lubricating oil pump and the cylinder air source. Close the lubricator structure to clamp the wire rope, and the pneumatic pump will discharge grease to start the lubrication operation.
