Description

Technical Field

[0001] The utility model relates to the technical field of port quay crane equipment, in particular to a drip irrigation system for lubricating a quay crane hoisting wire rope. Background Art

[0002] During the use of the quay crane lifting wire rope of the port quay crane equipment, the quay crane lifting wire rope will wear and rust due to lack of lubrication. During the use, lubricating oil can be added to reduce the wear and rust of the quay crane lifting wire rope, thereby ensuring the safety of the use of the quay crane lifting wire rope and increasing the service life of the quay crane lifting wire rope.

[0003] When the traditional quay crane hoisting wire rope needs to be lubricated, most of them use manual lubrication methods, such as: ① Use a hand to apply grease to the quay crane hoisting wire rope; ② Use a roller or a brush to roll the lubricant onto the quay crane hoisting wire rope. There are also ways to lubricate through ordinary oiling devices, such as: ① Use a drip irrigation method, that is, use a container to store the lubricant and use gravity to drip directly onto the quay crane hoisting wire rope; ② Use a special device to clamp the quay crane hoisting wire rope and pressurize the grease to the quay crane hoisting wire rope.

[0004] The disadvantages of traditional lubrication methods are: ① Manual lubrication has poor effect, much lubricating oil is wasted, long downtime is required, and human resources are wasted. ② Drip lubrication requires manual addition of lubricating oil during lubrication, and all the lubricating oil needs to be dripped once. The lubrication time and amount of lubricating oil are not convenient to control, and the lubrication effect is not good enough. ③ The special wire rope grease filling machine needs to be manually installed on the hoisting wire rope of the quay crane in a stopped state. The device is relatively bulky and requires a long downtime, which takes up a lot of equipment attendance time and has high labor costs. ④ The existing automatic lubrication device for wire ropes of quay cranes requires the equipment to be stopped and then installed on the hoisting wire rope of the quay crane by personnel before lubrication can be carried out. It is impossible to control the timing of lubricating oil filling according to the operating status of the equipment during the operation of the equipment. The above shortcomings restrict the operating efficiency of the quay crane equipment, thereby affecting the operating efficiency of the port.

[0005] The invention application with application number 201910466920.5 discloses a crane wire rope lubrication device, which includes a housing, a locking cover, two lubricating layers, two heating layers and a grease delivery assembly. The housing includes two semi-cylinders with the same structure, the locking cover is respectively connected to the two ends of the two semi-cylinders, the locking cover is used to connect the two semi-cylinders, the locking cover is provided with a rope hole, the two lubricating layers and the two heating layers are both semi-cylinder-shaped, the two lubricating layers are coaxially arranged in the two semi-cylinders of the housing, the two heating layers are coaxially arranged in the two semi-cylinders of the housing, one heating layer is sandwiched between one lubricating layer and one semi-cylinder, a spiral groove is provided on the inner wall of the lubricating layer, and the grease delivery assembly is used to deliver grease to the lubricating layer. The technical solution of the invention application adopts lubricating paste to lubricate by heating and pressurizing, which cannot realize the lubrication of the wire rope by the quay crane in real time according to the operation status of the equipment during operation, especially when the equipment needs to be assembled during maintenance, which requires more personnel and downtime.
