DETAILED DESCRIPTION

[0022] In the following, only certain exemplary embodiments are briefly described to make the objects, features, and advantages of the present invention more readily apparent. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 4 As shown, the utility model provides an automatic maintenance device for a tower crane wire rope, comprising: a tower crane 1; a pulley block 2 that can be connected to a wire rope is arranged on the tower crane 1; a lubricating mechanism 3 for lubricating the pulley block 2; a liquid supply mechanism 4 that can provide lubricant to the lubricating mechanism 3; one end of the liquid supply mechanism 4 is arranged on the tower crane 1, and the other end of the liquid supply mechanism 4 is connected to the lubricating mechanism 3; a temperature sensor 5; the temperature sensor 5 is arranged on the tower crane 1 and is located on a side close to the pulley block 2, and the temperature sensor 5 is connected to the lubricating mechanism 3.

[0025] In this embodiment, the wire rope is wound around the pulley block 2 in the tower crane 1, and the liquid supply mechanism 4 is connected to the lubricating mechanism 3 to provide lubricant to the lubricating mechanism 3; the working principle of this device is as follows: when the wire rope lacks lubrication, the friction between the wire rope and the pulley block 2 will increase, causing the temperature to rise. At this time, the temperature sensor 5 on the side can detect the temperature change. When the expected temperature is exceeded, the temperature sensor 5 can send an electrical signal to the lubricating mechanism 3, so that the lubricating mechanism 3 will evenly spray the lubricant onto the wire rope of the pulley block 2, thereby achieving the lubrication and maintenance effect of the wire rope. The above maintenance process does not require manual operation, which has high work efficiency and reduces safety hazards.

[0026] Furthermore, the lubrication mechanism 3 includes: a conduit 31 and a lubrication nozzle 32; a water pump 33 is provided on the conduit 31; the conduit 31 is provided on the liquid supply mechanism 4; the lubrication nozzle 32 is provided on the conduit 31, and the lubrication nozzle 32 faces one side of the pulley group 2; the water pump 33 is connected to the temperature sensor 5.

[0027] In this embodiment, the conduit 31 is C-shaped. One end of the conduit 31 is connected to the liquid supply mechanism 4, and the other end passes around the tower crane 1 and faces the pulley block 2. The lubrication nozzle 32 is provided at the end of the conduit 31 facing the pulley block 2. The water pump 33 is provided on the conduit 31 and is electrically connected to the temperature sensor 5.

[0028] When the temperature sensor 5 detects that the temperature of the wire rope of the pulley block 2 rises, it sends a working signal to the water pump 33, so that the water pump 33 pumps the lubricant in the liquid supply mechanism 4 to the lubricating nozzle 32 through the conduit 31 for output, thereby spraying the lubricant onto the wire rope through the lubricating nozzle 32 for lubrication maintenance.

[0029] Furthermore, the liquid supply mechanism 4 includes: a cylinder 41, a motor 42 and a stirring assembly; a accommodating chamber for storing lubricant is provided in the cylinder 41; a sealing assembly for closing the accommodating chamber is provided on one side of the cylinder 41; the cylinder 41 is provided on the tower crane 1; the motor 42 is provided on the outside of the cylinder 41; one end of the stirring assembly is rotatably provided in the accommodating chamber, and the other end of the stirring assembly is connected to the driving end of the motor 42; the conduit 31 is connected to the accommodating chamber.

[0030] In this embodiment, the cylinder 41 is detachably mounted on the tower crane 1, the stirring assembly is disposed in the accommodating chamber and is connected to the motor 42, and the stirring assembly can stir the lubricant in the accommodating chamber; the sealing assembly is disposed on one side of the cylinder 41, which can achieve a sealing effect on the accommodating chamber; the conduit 31 is connected to the accommodating chamber, and the lubricant in the accommodating chamber can flow into the conduit 31 under the action of the water pump 33.

[0031] Furthermore, the stirring assembly includes: a mounting rod 61; a plurality of stirring rods 62 are arranged on the mounting rod 61; a scraper 63 is provided at the end of each of the stirring rods 62; the mounting rod 61 is rotatably arranged in the accommodating cavity, and the mounting rod 61 is connected to the driving end of the motor 42.

[0032] In this embodiment, the mounting rod 61 is longitudinally arranged in the accommodating chamber and is connected to the driving end of the motor 42. When the motor 42 is working, it can drive the mounting rod 61 to rotate in the accommodating chamber; multiple stirring rods 62 are arranged on both sides of the mounting rod 61, and the end of the stirring rod 62 has a scraper 63. When the mounting rod 61 rotates, it can drive the scraper 63 on the stirring rod 62 to move in a circular motion in the accommodating chamber, so that the scraper 63 can scrape off and clean the lubricant remaining on the inner wall of the accommodating chamber, thereby achieving a cleaning effect inside the cylinder 41.

[0033] Furthermore, the sealing assembly includes: a cover plate 71 ; at least one buckle 72 is provided on the cover plate 71 ; and at least one socket 73 correspondingly adapted to and detachably connected to the buckle 72 is provided on the cylinder 41 .

[0034] In this embodiment, two clips 72 are symmetrically arranged on both sides of the cover plate 71, and two sockets 73 are correspondingly provided on the cylinder 41. When the clips 72 and the sockets 73 are connected to each other, the accommodating cavity can be closed. When the clips 72 and the sockets 73 are separated from each other, the cover plate 71 can be separated from the cylinder 41, which is convenient for adding lubricant to the accommodating cavity and regularly maintaining the stirring assembly in the accommodating cavity.

[0035] Furthermore, an electric heating wire 43 is sleeved on the outer side of the cylinder 41 to heat and keep the cylinder 41 warm.

[0036] In this embodiment, the heating wire 43 is sleeved on the outside of the cylinder 41. The heating wire 43 can heat the cylinder 41 to keep the lubricant inside the cylinder 41 at a constant temperature to prevent the lubricant from condensing when it is cooled in low temperature weather.

[0037] Furthermore, it also includes a limiting mechanism 8; the limiting mechanism 8 includes: a support rod and a limiting ring; the support rod is arranged on the tower crane 1; one end of the limiting ring is arranged at the end of the support rod, and the other end of the limiting ring is connected to the conduit 31.

[0038] In this embodiment, the support rod is installed on the tower crane 1, the limiting ring is installed at the end of the support rod and connected to the conduit 31, and the limiting mechanism 8 can position the conduit 31 to prevent the conduit 31 from deflecting during operation.

[0039] Furthermore, it also includes a collecting mechanism 9; the collecting mechanism 9 includes: a fixing part and a collecting box; the fixing part is arranged on the tower crane 1 and is located below the pulley block 2; the collecting box is detachably arranged on the fixing part.

[0040] In this embodiment, the fixing part is arranged at the lower end of the tower crane 1, and the collecting box is arranged on the fixing part and is located below the pulley block 2. When the lubricating mechanism 3 applies the lubricant to the pulley block 2, there will be a certain amount of lubricant surplus, which will drip under the action of gravity. The collecting box can receive the above-mentioned dripping lubricant, thereby preventing the leaked oil from polluting the surrounding environment of the equipment.

[0041] Furthermore, it also includes an external connection mechanism 10; the external connection mechanism 10 includes: a connecting piece and a lifting ring; the connecting piece is arranged on the top of the tower crane 1; the lifting ring is movably arranged on the connecting piece.
