Description of the Drawings
[0011] Figure 1 is the structural diagram of the maintenance tool for the blind area of the steel wire rope of the dock crane of the present utility model;
[0012] In the figure, 1 - sleeve, 2 - pull ring, 3 - screw, 4 - connecting plate; Detailed Implementation Manner
[0013] As Figure 1 shown, the present utility model discloses a maintenance tool for the blind area of the steel wire rope of a dock crane. The maintenance tool for the blind area of the steel wire rope of the dock crane includes a sleeve 1 with a receiving cavity. Both the upper and lower ends of the sleeve 1 are provided with openings. The upper opening of the sleeve 1 is arranged at the top of the receiving cavity. The aperture of the upper opening of the sleeve 1 is larger than that of the lower opening to facilitate filling of lubricating oil. The aperture of the lower opening of the sleeve 1 is slightly larger than the diameter of the steel wire rope to control the oil output and maintain free movement. When using this tool, the operation and maintenance personnel of the crane only need to put the tool on the steel wire rope. Since there is a gap between the inner surface of the lower opening of the sleeve 1 and the outer surface of the steel wire rope, the lubricating oil in the receiving cavity will flow from the gap to the outer surface of the steel wire rope. By pulling the towing rope, the tool makes a reciprocating movement on the steel wire rope, so as to ensure that the lubricating oil is evenly applied on the surface of the steel wire rope.
[0014] The sleeve 1 includes a first housing and a second housing. The first housing and the second housing are installed together to form the sleeve 1, and the first housing and the second housing are detachably installed.
[0015] The maintenance tool for the blind area of the steel wire rope of the dock crane further includes a connecting plate 4 with a mounting hole and a screw 3. The connecting plates 4 are symmetrically arranged on the first housing and the second housing, and the first housing and the second housing are installed together through the connecting plate 4 and the screw 3.
[0016] The sleeve 1 is in a cylindrical shape.
[0017] The maintenance tool for the blind area of the steel wire rope of the dock crane further includes a pull ring 2. The pull rings 2 are symmetrically arranged on both sides of the sleeve 1 respectively. The pull rings 2 are used for tying the towing rope, so as to realize the free movement of the tool on the steel wire rope.
[0018] The number of the pull rings 2 is four, and two pull rings 2 are symmetrically arranged on each side of the sleeve 1 respectively.
[0019] The number of connecting plates 4 is eight, with four connecting plates respectively arranged on the first housing and the second housing, and the number of screws is four.
[0020] For the maintenance tool for the blind area of the steel wire rope of a dock crane disclosed by the present utility model, the upper end of the sleeve 1 is set in an open form, which is convenient for filling lubricating oil.
[0021] The using steps of the maintenance tool for the blind area of the steel wire rope of the dock crane are as follows:
[0022] Step 1: Separate the sleeve 1 into two parts and sleeved them on the steel wire rope.
[0023] Step 2: Connect the two parts of the sleeve 1 through the bolt 3.
[0024] Step 3: Fill lubricating oil from the upper end of the sleeve 1.
[0025] Step 4: Connect the towing rope with the pull ring 2, and pull the towing rope to make the tool move back and forth on the steel wire rope.
