[0050] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.
[0051] Embodiment 1:
[0052] like Figure 1-Figure 5 As shown, the wire rope anti-jump oil blocking structure of this embodiment includes:
[0053] The oil retaining groove assembly 1 is installed on the lifting device 2 and sleeved on the outer side of the lower part of the two drums 22 of the lifting device 2. The oil retaining groove assembly 1 is provided with a semi-annular groove matching the drum 22. The inner surface of the semi-annular groove and the outer peripheral surface of the drum 22 form an assembly gap. The semi-annular groove is used to collect oil and limit the loose wire rope on the drum 22 to the inside of the semi-annular groove;
[0054] The oil guide hole 10 is arranged at the bottom of the semi-annular groove;
[0055] The rope retaining member 3 is installed on the oil retaining groove assembly 1, and the rope retaining member 3 presses the loose wire rope on the drum 22;
[0056] The oil collecting box 4 is detachably mounted on the outside of the oil retaining groove assembly 1 and corresponds to the oil guide hole 10 for collecting grease.
[0057] Specifically, the lifting device 2 is installed on the column of the stacker through the mounting plate 5. The lifting device 2 includes a motor 21 and a drum 22 connected to the output shaft of the motor 21, and a steel wire rope is wound on the drum 22;
[0058] The oil retaining groove assembly 1 is sleeved on the outer side of the lower part of the drum 22 and has a semi-annular groove structure inside. The groove structure of the semi-annular groove is semi-annular in length direction. The semi-annular groove protects and collects oil from the lower half of the drum 22. The assembly gap is to reserve space for the wire rope outside the drum 22. The upper edge of the surrounding part of the semi-annular groove is close to or higher than the axis of the drum 22, which effectively prevents the wire rope from jumping grooves and oil splashing. The oil retaining groove assembly 1 can be disassembled as a whole if the conditions are met, such as Figure 4 As shown; the rope blocking member 3 is about 5mm away from the wire rope during the normal winding process of the wire rope, and prevents the wire rope from jumping out when the wire rope becomes loose; the grease on the wire rope is blocked and collected by the semi-annular groove and flows into the oil collecting box 4 from the oil guide hole 10. There is no need to disassemble the oil blocking groove assembly 1 as a whole, and the grease can be dumped by only disassembling the oil collecting box 4. It is convenient and quick, and only one person can operate it.
[0059] By installing an oil retaining groove assembly 1 on the outer side of the lower part of the lifting device 2, the oil retaining groove assembly 1 has a semi-annular groove matching the drum 22 and a rope blocking member 3 for blocking the wire rope, thereby preventing oil leakage from the drum and wire rope jumping. The semi-enclosed structure can facilitate observation of the specific situation of the wire rope on the drum, reducing the difficulty of repairing and maintaining the wire rope. In addition, the detachable oil collecting box 4 also improves the maintenance efficiency.
[0060] Further, if Figure 1-Figure 7 As shown, the lifting device 2 includes a motor 21, and the output shaft of the motor 21 is connected to the drum 22; the structure of the oil retaining tank assembly 1 includes:

[0063] Specifically, the connecting member 13 is connected to the inherent mounting hole on the base 23 by using a fastener.
[0064] A split structure is adopted, and semi-annular grooves are respectively set corresponding to the two reels 22, so as to reduce the material consumption in making the oil retaining groove assembly 1 and reduce the overall weight of the oil retaining groove assembly 1, so that the weight can be installed by one person, making disassembly and assembly convenient, saving labor costs, saving time and effort, and directly connecting the connecting piece 13 to the base 23 of the motor 21 to simplify the installation structure.
[0065] Further, if Figure 4 , Figure 5-Figure 8 As shown, the first oil retaining groove 11 has the same structure as the second oil retaining groove 12, and the structure of the first oil retaining groove 11 includes:
[0066] The arc plate 1101 has an arc-shaped cross section, and the axis of the arc plate 1101 is consistent with the axis of the reel 22;
[0067] Two arc-shaped baffles 1102 are respectively installed at two axial ends of the arc-shaped plate 1101 to form a semi-annular groove with the arc-shaped plate 1101 .
[0068] Specifically, the gap between the inner surface of the arc plate 1101 and the outer surface of the reel 22 is the assembly gap; the arc baffle 1102 is in the form of a sheet, and the arc baffle 1102 and the arc plate 1101 are assembled into the first oil baffle groove 11 by welding, and then welded as a whole at the end position of the connecting piece 13; the connecting piece 13 is a rod-shaped structure, which can be formed by bending sheet metal or a finished profile.
[0069] The split oil retaining groove assembly 1 shortens the width of the arc plate 1101 and reduces the difficulty of forming.
