At this time, the conversion device 11 controls the lubrication device 10 to be in an open state; then the electronically controlled frame 1 is controlled to operate toward the crane main machine, so that the connecting frame 2 and The hoist 3 moves, thereby driving the central frame 5 to move, so that the two sets of lubricating devices 10 are on the same plane as the cables of the crane main machine.

The oil tank and its pump 91 are fixedly connected to the central frame 5. The main oil pipe 92 is fixedly connected to the fixed frame 6. The main oil pipe 92 is connected to the oil tank and its pump 91. Spring tubes 93 are fixedly connected on both sides of the main oil pipe 92. The spring tubes 93 are respectively connected to the adjacent lubrication devices 10.

[0047] When this embodiment is working: the oil tank and its pump 91 are started, and the lubricating grease stored in the oil tank and its pump 91 is pumped to the lubricating device 10 through the main oil pipe 92 and the spring tube 93, and the crane cable is lubricated and maintained through the lubricating device 10.

One side of the surrounding plate 106 and the three directions of the three-sided surrounding frame 102 are fixedly connected with a nozzle 107, and a hose 108 is fixedly connected to the nozzle 107 at the surrounding plate 106. A manifold 109 is connected between the three nozzles 107 at the three-sided surrounding frame 102, and the hose 108 is connected to the adjacent manifold 109, and the manifold 109 is respectively connected to the adjacent spring tubes 93.

[0049] This embodiment is working: when the propulsion device 12 drives the two groups of sliding frames 8 to move in opposite directions, the sliding frames 8 move away from each other on the mounting plate 7. At this time, the three-sided surrounding frames 102 and the surrounding plates 106 are in a separated state, that is, in an open state; when the electric control frame 1 moves toward the crane main machine, the position between the two groups of three-sided surrounding frames 102 and the cables of the crane main machine are in the same plane. At this time, the propulsion device 12 can be controlled to operate again, so that the sliding frames 8 are close to each other on the mounting plate 7, and the position between the three-sided surrounding frames 102 respectively surrounds the adjacent cables, and then the propulsion device 12 is controlled to stop running, and the conversion device 11 is controlled to work, so that the conversion device 11 drives the first rotating shaft 103 to rotate respectively through the first belt transmission assembly 104, thereby driving the first movable arm 105 and the surrounding plate 106 to rotate, so that the surrounding plate 106 contacts the adjacent three-sided surrounding frames 102, thereby The three-sided enclosing frame 102 and the enclosing plate 106 are formed into a closed state, so that the cable is completely enclosed, and at this time the propulsion device 12 is in a disconnected propulsion state, and the sliding frame 8 is in a freely sliding state; the three-sided enclosing frame 102 and the enclosing plate 106 move downward on the cable by gravity, and the oil supply device 9 can be started at this time. The oil supply device 9 will spray lubricating oil on the surface of the cable through the manifold 109, the hose 108 and the nozzle 107 to lubricate and maintain the cable; after the lubrication maintenance of the crane cable is completed and the upward movement and reset of the central frame 5 is completed, the conversion device 11 can be controlled to reset and operate, so that the conversion device 11 drives the first rotating shaft 103 to reverse, and the first movable arm 105 drives the enclosing plate 106 to reverse, so that the enclosing plate 106 is separated from the contact with the three-sided enclosing frame 102, so that the three-sided enclosing frame 102 is in an open state, and then the self-propelled lubrication maintenance equipment based on port crane machinery is withdrawn.

[0050] like Figure 9-14 As shown, the conversion device 11 includes a support frame 111, a dual-axis motor 112, a crankshaft 113 and a straight shaft 114. The sliding frame 8 is fixedly connected to the support frame 111 at a position away from the mounting plate 7. The dual-axis motor 112 is fixedly connected to the support frame 111. The output shaft of the dual-axis motor 112 fixed at a position near the first rotating shaft 103 is fixedly connected to the crankshaft 113. The other end of the crankshaft 113 is connected to the adjacent first belt transmission assembly 104. The propulsion device 12 is respectively arranged at the crankshaft 113. The output shaft on the other side of the dual-axis motor 112 is fixedly connected to the straight shaft 114.

[0051] This embodiment is working: when controlling the conversion device 11, the dual-axis motor 112 will work, the dual-axis motor 112 will drive the crankshaft 113 and the straight shaft 114 to rotate, and the crankshaft 113 will drive the propulsion device 12 and the first belt drive assembly 104 to rotate; when the crankshaft 113 drives the first movable arm 105 to rotate until it contacts the three-sided enclosing frame 102, the propulsion device 12 will then leave the propulsion state, and when the crankshaft 113 drives the first movable arm 105 to reverse and reset so that it leaves the contact with the three-sided enclosing frame 102, the propulsion device 12 will re-enter the propulsion state.

[0052] like Figure 9-16 As shown, the propulsion device 12 includes a rotating frame 121, a moving pair 122, an elastic member 123, an electric hub 124 and a guide path 125.

[0053] This embodiment is working: when the crankshaft 113 drives the first movable arm 105 to rotate to contact the three-sided surrounding frame 102, the electric wheel hub 124 will be out of contact with the guide path 125, that is, out of the propulsion state, so that the sliding frame 8 has automatic sliding properties on the mounting plate 7; when the crankshaft 113 drives the first movable arm 105 to reverse and reset so that it is out of contact with the three-sided surrounding frame 102, the electric wheel hub 124 will be in contact with the guide path 125 again, and the elastic member 123 and the movable pair 122 will make the electric wheel hub 124 close to the guide path 125, increasing the friction between the guide path 125 and the electric wheel hub 124, that is, re-entering the propulsion state.

[0054] By adopting a conversion device and a propulsion device, the sliding frame can have two movement modes on the mounting plate: electric control movement and free sliding. When the sliding frame performs point electric control movement, it can quickly reset and position the cables. When the sliding frame performs free sliding, the lubrication device can perform lubrication maintenance according to cables with different spacing and angles, thereby improving the applicability of the self-propelled lubrication and maintenance equipment based on port cranes.

[0055] Example 3

[0056] like Figure 9-13As shown, a protective device 13 is also included, which includes a second mounting frame 131, a first pressure sensor 132, an extension frame 133, a second rotating shaft 134, a second belt transmission assembly 135, a second movable arm 136 and a roller 137. There are two groups of protective devices 13, each of which is provided at a position of the sliding frame 8 away from the lubrication device 10. The protective device 13 is used to further protect the crane cable. The sliding frame 8 is fixedly connected to the second mounting frame 131 at a position away from the first mounting frame 101. The other side of the second mounting frame 131 is fixedly connected to the first pressure sensor 132, and the other side of the first pressure sensor 132 is fixedly connected to the extension frame 133. The second mounting frame 131 is rotatably connected to a second rotating shaft 134, and a second belt drive assembly 135 is connected between the second rotating shaft 134 and the straight shaft 114. The second belt drive assembly 135 is belt driven, and a second movable arm 136 is fixedly connected to the second rotating shaft 134. The other side of the second movable arm 136 and the extension frame 133 are rotatably connected to rollers 137. There are three rollers 137 at the extension frame 133, and the positions of the rollers 137 at the extension frame 133 correspond to the three-sided encircling frame 102. There is one roller 137 at the second movable arm 136, and the position of the roller 137 at the second movable arm 136 corresponds to the encircling plate 106.

[0057] This embodiment is in operation: when the enclosing plate 106 is not in contact with the three-sided enclosing frame 102, the second movable arm 136 and the roller 137 at the extension frame 133 are not in the enclosing state; when the crane cable is between the three-sided enclosing frame 102, the crane cable is also between the rollers 137 at the extension frame 133; when the dual-axis motor 112 rotates, the dual-axis motor 112 will drive the first belt transmission assembly 104 and the second belt transmission assembly 135 to rotate, thereby driving the first movable arm 104 to rotate. 5 and the second movable arm 136 rotate, so that the enclosing plate 106 and the three-sided enclosing frame 102 surround the cable, and at this time the roller 137 also surrounds the cable, so that when the self-propelled lubrication maintenance device based on the port crane is moving, the crane cable will not directly contact with the three-sided enclosing frame 102 and the enclosing plate 106 and be damaged by friction, but the roller 137 provides rolling friction, thereby achieving the purpose of protecting the cable; and when the three-sided enclosing frame 102 and the enclosing plate 106 are in an open state and moving When the two sides move close to each other to search for a cable, when the roller 137 at the extension frame 133 contacts the cable, the first pressure sensor 132 will detect that the second pressure sensor 141 is in a stressed state. At this time, the first pressure sensor 132 will control the dual-axis motor 112 to automatically operate, so that the dual-axis motor 112 drives the roller 137 at the enclosing plate 106 and the second movable arm 136 to rotate, so that the rollers 137 are in an encircled state, the encircling plate 106 and the three-sided encircling frame 102 are in an encircled state, and the electric hub 124 is separated from the guide path 125. At the same time, the first pressure sensor 132 will control the oil supply device 9 to work, so that it automatically supplies lubricating oil. Then, the first pressure sensor 132 will control the winch 3 to automatically release the lifting cable 4, so that the self-propelled lubrication and maintenance equipment based on the port crane automatically descends to lubricate the crane cable, thereby further improving the degree of automation of the self-propelled lubrication and maintenance equipment based on the port crane when maintaining the cable.

[0058] By further surrounding the cable with the roller of the protective device, the cable can be protected from direct friction during the maintenance and lubrication process. By adopting the rolling friction between the roller and the cable, the cable can be protected during the maintenance process. Moreover, through the action of the first pressure sensor, the self-propelled lubrication maintenance equipment based on the port crane can be further automated and intelligent.

[0059] like Figure 5As shown, it also includes a limit component 14, which includes a second pressure sensor 141 and a contact wheel 142. The limit component 14 is arranged on the side of the fixed frame 6 away from the mounting plate 7. The limit component 14 is used to limit the descent height of the self-propelled lubrication maintenance equipment based on the port crane. The second pressure sensor 141 is fixedly connected to the side of the fixed frame 6 away from the mounting plate 7, and the contact wheel 142 is rotatably connected to the other side of the second pressure sensor 141.

[0060] This embodiment is in operation: when the self-propelled lubrication maintenance device based on the port crane moves downward, when the contact wheel 142 contacts the hook part of the crane, the second pressure sensor 141 will detect the pressure value, and the second pressure sensor 141 will control the winch 3 to retract the lifting cable 4, thereby driving the self-propelled lubrication maintenance device based on the port crane to automatically move upward and reset. In this way, the maintenance automation and intelligence of the port crane cables can be further improved.

[0061] like Figure 5 As shown, weak resistance rods 15 are also included, and the weak resistance rods 15 are fixedly connected to the mounting plate 7 at a position near one side of the three-sided surrounding frame 102.

[0062] This embodiment is working: when the self-propelled lubrication and maintenance equipment based on port crane runs toward the crane main engine, the weak resistance rod 15 will first contact the crane cable. When the weak resistance rod 15 contacts the crane cable, the weak resistance rod 15 will change the current level of the power path where it is located, indicating that the weak resistance rod 15 is contacted by the crane cable. At this time, the power path where the weak resistance rod 15 is located will control the electric control frame 1 to stop running, which can further improve the degree of automation of the self-propelled lubrication and maintenance equipment based on port crane.

[0063] By installing a weak resistance rod at a position on one side of the surrounding frame on three sides of the mounting plate, the self-propelled lubrication and maintenance equipment based on the port crane is driven to move by the electric control frame so that the weak resistance rod contacts the crane cable, and then the electric control frame is controlled to stop automatically. This allows the self-propelled lubrication and maintenance equipment based on the port crane to position the crane cable automatically and accurately.

[0064] Through the coordination of the oil supply device, lubrication device, conversion device, propulsion device, protection device and limit assembly, the maintenance process of the crane cable can be automated and intelligent, the cable can be protected during the lubrication maintenance process, and manual climbing at high positions for lubrication operations can be avoided, thereby ensuring the safety of manual labor and achieving a high degree of automation and intelligence in the cable lubrication maintenance process.

[0065] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
