[0049] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by those skilled in the art belong to the scope of protection of the utility model.

[0050] The shore-to-ship bridge steel wire rope lubricating system according to the embodiments of the utility model will be described in detail below in combination with the drawings.

[0051] Figure 1 The shore-to-ship bridge steel wire rope lubricating system according to the embodiments of the utility model will be described in detail below in combination with the drawings. Figure 1 The shore-to-ship bridge steel wire rope lubricating system according to the embodiments of the utility model will be described in detail below in combination with the drawings.

[0052] In this embodiment, multiple lubrication points can be provided on the shore-to-ship bridge, such as Figures 2-9As shown, the lubrication points can be arranged at the front girder 300, the ladder frame 400, the trolley frame 500 and the rear girder 600 of the shore crane. Taking the shore crane steel wire rope lubrication system of the utility model arranged on the front girder 300 of the shore crane as an example, the centralized lubrication mechanism 100 can be arranged at the two groups of pulleys 101 on the front girder 300. When the maintenance personnel climb onto the front girder 300 for maintenance, the electric control mechanism 200 arranged on the front girder 300 can be used to directly control the centralized lubrication mechanism 100 to lubricate the steel wire rope on the pulley 101 in a timed and quantitative manner, for example, the centralized lubrication mechanism 100 can be controlled to lubricate 20 milliliters of lubricating oil to the steel wire rope on the pulley 101 every 12 hours. When the maintenance personnel do not climb onto the shore crane, the host computer 260 arranged on the ground can be used, for example, the main PLC of the shore crane electrical room can be used to remotely control the centralized lubrication mechanism 100 to lubricate the steel wire rope on the pulley 101 in a timed and quantitative manner through the electric control mechanism 200. Thus, the labor cost can be effectively reduced, and the lubrication efficiency of the steel wire rope can be improved. Moreover, since manual intervention is not required, the shore crane does not need to be stopped during the lubrication of the steel wire rope, thereby effectively improving the production efficiency. Meanwhile, since the lubrication mechanism can lubricate the steel wire rope on the pulley 101 in a timed and quantitative manner, the lubrication effect can be improved while saving lubricating oil, and the equipment around can be prevented from being contaminated by the lubricating oil.

[0053] As shown in the Figures 2-9 centralized lubrication mechanism 100 includes a lubricating pump station (not shown) and a plurality of lubricating brushes 120. The lubricating pump station is connected to each lubricating brush 120, and is used to lubricate each lubricating brush 120 with lubricating oil. Each lubricating brush 120 is used to abut the steel wire rope on the corresponding pulley 101 at the lubrication point. Thus, the lubricating pump station is used to lubricate the lubricating brush 120 abutting the steel wire rope with lubricating oil, and manual lubrication of the steel wire rope is not required, thereby effectively saving labor and improving the lubrication efficiency of the steel wire rope.

[0054] As shown in the Figures 2-9 lubricating pump station includes an oil tank (not shown), an electromagnetic pump (not shown), a plurality of oil path pipelines 111 and a plurality of electromagnetic valves (not shown). The oil tank is used to store lubricating oil. The inlet of the electromagnetic pump is communicated with the oil tank. Each oil path pipeline 111 is connected to the outlet of the electromagnetic pump at one end and to the corresponding lubricating brush 120 at the other end. The electromagnetic pump is used to lubricate each lubricating brush 120 with lubricating oil in the oil tank through each oil path pipeline 111. The plurality of electromagnetic valves are arranged on the corresponding oil path pipelines 111. Each electromagnetic valve is used to open or close the corresponding oil path pipeline 111.

[0055] In the embodiment, the electric control mechanism 200 and the host computer 260 can start or stop the electromagnetic pump at a fixed time, so that the steel wire rope on the pulley 101 can be lubricated at a fixed time. Meanwhile, the electric control mechanism 200 and the host computer 260 can start or stop the electromagnetic valve at a fixed time, so that the steel wire rope on the pulley 101 can be lubricated at a fixed amount. Thus, the lubrication effect can be improved while saving lubricating oil, and the surrounding equipment can be prevented from being polluted by the lubricating oil.

[0058] In the embodiment, the opening or closing of the electromagnetic pump and each electromagnetic valve is controlled by using the local control module or the remote communication module, such as the synchronous opening or closing of the electromagnetic pump and each electromagnetic valve at a fixed time, so that the accumulation of lubricating oil in the oil circuit pipeline 111 can be avoided. Meanwhile, the local control module is electrically connected with each electromagnetic valve, so that the host computer 260 can control the opening or closing of any electromagnetic valve through the local control module when communicating with the remote communication module, and thus the operator can lubricate the steel wire rope on the pulley 101 according to the actual situation on site. In addition, the local control module and the remote module can control the emergency closing of the electromagnetic pump and each electromagnetic valve, so that the electromagnetic pump and each electromagnetic valve can be closed in an emergency, thereby improving the safety performance.

[0059] In an embodiment of the utility model, the host computer 260 communicates with the remote communication module through a Profibus DP.

The switch 250 is also used for resetting the electromagnetic pump and each electromagnetic valve after the electromagnetic pump and each electromagnetic valve stop urgently.

[0061] In the embodiment, the operator can switch to the local control module or the remote communication module through the switch 250. When the local control module is turned on through the switch 250, the start button 220, the stop button 230, and the emergency stop knob 240 are electrically connected with the local control module. Specifically, the start button 220 can turn on the local control module and control the electromagnetic pump and each electromagnetic valve to open synchronously and regularly through the local control module, so as to lubricate each lubricating brush 120. The stop button 230 can turn off the local control module and control the electromagnetic pump and each electromagnetic valve to close synchronously and regularly through the local control module.
