Embodiment 1

[0035] An embodiment of the present invention provides a wire rope luffing crane, see Figure 1-Figure 4 , the crane includes a crane platform 10, a boom 101, an A frame 102, a luffing winch 103, a luffing block 112 and a wire rope 104, the A frame 102 and the luffing winch 103 are fixed on the crane platform 10, and the luffing winch 103 is set at the bottom of the A-frame 102, the top of the A-frame 102 is provided with a luffing pulley block 121, one end of the jib 101 is connected to the crane platform 10 and can rotate around the crane platform 10, and the other end of the jib 101 is provided with a pulley 111 , the pulley 111 is connected with the luffing block 112 through a rope 113, and the crane also includes a lubricating winch 105, which is arranged side by side with the luffing winch 103, and one end of the steel wire rope 104 is fixed on the luffing winch 103, and the other end of the steel wire rope 104 is bypassed After the luffing pulley block 121 is close to t...

Embodiment 2

[0050] The embodiment of the present invention provides a crane steel wire rope lubrication method, which is suitable for the crane in the first embodiment, see Figure 5 , the method includes:

[0051] Step 201: When the lubricating winch is in a braking state, control the luffing drum to lower the boom.

[0052] Since the lubricating winch is in the braking state when the crane is in the hoisting state, in order to select suitable equipment to minimize the cost of the crane, before step 201, the method may further include: analyzing the stress on the lubricating winch in the hoisting state, Determine the braking force required for the brakes and the structural strength required to lubricate the winch.

[0053] Step 202: Control the luffing drum to unwind the rope so that the wire rope is in a slack state.

[0054] Step 203: Control the lubricating winch to take in the rope.

[0055] Specifically, step 203 includes:

[0056] Use electric power, hydraulic pressure or manua...

Abstract

The invention discloses a steel wire rope luffing crane and a lubrication method for the steel wire rope of the crane, belonging to the field of hoisting machinery. The crane comprises a crane platform, a jib, an A-shaped rack, a luffing winch, a luffing trolley, a steel wire rope and a lubricating winch, wherein the A-shaped rack and the luffing winch are fixed on the crane platform, the luffing winch is arranged at the bottom of the A-shaped rack, the top of the A-shaped rack is provided with a luffing pulley block, one end of the jib is connected with the platform and can rotate around the platform, the lubricating winch and the luffing winch are arranged side by side, one end of the steel wire rope is fixed on the luffing winch, the other end of the steel wire rope successively winds around the luffing trolley and pulleys of the luffing pulley block after winding around the outmost pulley, close to one side of the luffing winch, of the luffing pulley block and then returns back from the outmost pulley at the other side of the luffing pulley block, and the other end of the steel wire rope is finally fixed on the lubricating winch. During lubrication of the steel wire rope, operation is convenient, and the steel wire rope can be conveniently maintained.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a steel wire rope luffing crane and a method for lubricating the steel wire rope of the crane. Background technique [0002] Offshore platform cranes are generally installed on various offshore platforms and workboats for deep sea operations. Due to the complex working environment and compact structure of the platform or workboat where the offshore platform crane is located, it is usually very difficult to install and disassemble the steel wire rope, and the maintenance cost is high. Especially the wire rope luffing crane, this type of crane achieves the purpose of jib luffing by winding the wire rope through the luffing winch. structurally. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] The steel wire rope is in the highly corrosive environment of the ocean. The steel wi...
