[0005] This utility model relates to a wire rope lubrication device for a tower crane hoisting mechanism, comprising:

[0006] The installation mechanism includes a set of symmetrically arranged mounting brackets and a top rod, wherein the top rod is fixed to the upper end of the set of mounting brackets;

[0007] The oil injection mechanism includes a guide frame and an oil injection tank.

The oil injection tank is located on the front of the guide block, and limit rods are symmetrically fixed on the lower part of the front of the oil injection tank. The inner side of a set of limit rods is in contact with the surface of the extension end of the wire rope.

[0008] Furthermore, the guide block has a mounting hole block fixed on its front side, and the front side of the mounting hole block fits against the back side of the oil tank. The threaded holes at the corners of the mounting hole block extend into the back side of the oil tank.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a wire rope oil injection device for the hoisting mechanism of a tower crane, comprising:

[0026] The installation mechanism includes a set of symmetrically arranged mounting brackets 11 and a top rod 13, with the top rod 13 fixed to the upper end of the set of mounting brackets 11.

[0027] Mounting bracket 11 provides a basic installation environment, and top rod 13 ensures the stability of the structure between a group of mounting brackets 11.

[0028] The mounting mechanism also includes an adjusting support column 12, the upper end of which is threaded into a threaded cavity at the bottom end of the support frame;

[0029] The adjustable support column 12 is threadedly connected to the mounting bracket 11. By utilizing the expansion and contraction characteristics of the thread, the length of the adjustable support column 12 can be adjusted. When used with the mounting bracket 11, it can meet the different height requirements of the oil tank 24.

[0030] A reinforcing crossbar 14 is fixed to the inner middle of the mounting bracket 11;

[0031] The connection characteristics between the reinforcing crossbar 14 and the mounting bracket 11 are enhanced.

[0032] The oil injection mechanism includes a guide frame 21 and an oil injection tank 24. The end of the guide frame 21 is fixedly connected to the upper inner side of a set of mounting frames 11, and a guide block 22 slides on the front of the guide frame 21. The oil injection tank 24 is located on the front of the guide block 22, and limit rods 27 are symmetrically fixed on the lower front of the oil injection tank 24. The inner side of a set of limit rods 27 is in contact with the surface of the extension end of the wire rope.

[0033] The guide block 22 has a mounting hole block 23 fixed on its front side, and the front side of the mounting hole block 23 fits against the back side of the oil tank 24. The threaded holes at the corners of the mounting hole block 23 extend into the back side of the oil tank 24.

[0034] The guide frame 21 provides a sliding base. The guide block 22 and the main oil tank are connected and fixed by the guide block 22 through the mounting hole block 23 in the threaded installation. The inner side of a set of limit rods 27 is in close contact with the extension end of the wire rope. When the wire rope is in the unwinding state, the linkage force can act on the limit rods 27, thereby linking the oil tank 24 to slide horizontally through the guide block 22 and the guide frame 21, so as to meet the multi-position lubrication and maintenance of the wire rope.

[0035] An opening is provided on one side of the top of the oil tank 24, and the opening is sealed. An oil injection pipe 25 is connected to the middle of the bottom of the oil tank 24, and an electromagnetic valve 26 is threaded on one side of the outer surface of the oil injection pipe 25.

[0036] The inlet is used to supply lubricating oil to the inside of the oil tank 24, and the sealing treatment prevents leakage. The oil injection pipe 25 discharges the oil inside the oil tank 24 to complete the oil injection treatment on the surface of the wire rope. The opening and closing of the solenoid valve 26 controls whether the flow inside the oil injection pipe 25 is controlled.

[0037] Working principle: During the lubrication and maintenance of the wire rope, the extended end of the wire rope is placed inside a set of limit rods 27. When the extended end of the wire rope is subjected to tension and unwinds on the drum, the force is transmitted to the limit rods 27 and then to the oil tank 24. By utilizing the sliding of the guide block 22 within the guide frame 21, the oil tank 24 can perform horizontal sliding movement. During the sliding process, by opening the solenoid valve 26, the wire rope can be mechanically lubricated and maintained without stopping the machine using the oil injection pipe 25.

[0038] This solution can proactively perform multi-position oiling and lubrication maintenance on the wire rope without stopping the machine or requiring manual operation, effectively improving maintenance and lubrication efficiency.

[0039] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0040] It also includes a collision buffer mechanism, which includes a support rod 31 and a buffer head 37. The support rods 31 are arranged symmetrically in a group, and a support column 33 is sleeved on one end of the support rod 31. A movable tube 34 is fixed to the outer end of the support column 33, and a movable spring 35 is fixed to the inner side of the movable tube 34. A movable column 36 is fixed to one end of the movable spring 35, and one end of the movable column 36 is fixed to the inner side of the buffer head 37.

[0041] The support rod 31 provides a basic installation environment. The movable tube 34 is installed through the support column 33. The movable column 36 and the movable tube 34 are connected by the movable spring 35. After the buffer head 37 and the mounting bracket 11 come into contact with each other, the movable column 36 can extend into the movable tube 34 with the help of the elastic extension force of the movable spring 35, avoiding long-term hard contact. Under the transmission of force, vibration will be generated, causing the position of the oil tank 24 to deviate or be damaged.

[0042] The other end of the support rod 31 is threaded through the locking post 32 and extends into the limiting rod 27. The outer end of the locking post 32 is provided with a hexagonal protrusion.

[0043] The locking pin 32 is installed and fixed to the support rod 31, and the locking pin 32 can be easily grasped with the help of the hexagonal protrusion to apply the force required for disassembly and assembly.

[0044] Working principle: During the horizontal sliding process, the oil tank 24 is isolated by the contact between the buffer head 37 and the mounting bracket 11. After the buffer head 37 contacts the mounting bracket 11, the force is transmitted to the movable column 36 and compresses the movable spring 35, causing the movable column 36 to extend into the movable tube 34. Subsequently, after the movable spring 35 recovers its deformation, the force is applied in the opposite direction to reduce and lower the stress state of the oil tank 24, thus protecting it.

[0045] This solution utilizes the limit rod 27 to provide positional limitation while also providing necessary protection, thereby enhancing the structural applicability and functionality.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
