[0002] Special climbing equipment refers to special equipment used for high-altitude operations or climbing tasks. It usually needs to have special functions and performance to meet specific work requirements. Climbing equipment usually uses a travel reducer to provide driving force and control the travel speed.

[0033] Specifically: the liquid outlet pipe 4 is connected to the bottom of the front side of the reducer body 2, and is used to discharge the lubricating oil inside the reducer body 2. The liquid inlet pipe 3 is connected to the top of the reducer body 2, and is used to discharge the cooled lubricating oil into the reducer body 2 again. The end of the liquid outlet pipe 4 away from the reducer is connected to the conveying shell 6, and the other side of the conveying shell 6 is connected to the heat dissipation pipe 10.

The first conveying gear 8 is meshed with the second conveying gear 9. When the second conveying gear When the wheel 9 starts to rotate, it drives the first conveying gear 8 to rotate together. During the meshing process of the gears, the tooth grooves between them will form a low-pressure area on the suction port side, generating suction, thereby sucking the liquid into the tooth grooves. As the gears continue to rotate, the sucked liquid is captured by the tooth grooves and moves along the inner wall of the conveying shell 6 toward the discharge port. When the tooth grooves of the gears reach the discharge port, the meshing of the gears causes the liquid in the tooth grooves to be squeezed out and discharged from the conveying shell 6 through the discharge port. This process is repeated every time the gears rotate, thereby achieving continuous liquid delivery.

[0034] For specific embodiment 2, please refer to Figure 1-5On the basis of the specific embodiment 1, the other end of the liquid inlet pipe 3 penetrates into the heat dissipation shell 5 and communicates with the heat dissipation pipe 10, the other end of the liquid outlet pipe 4 penetrates into the heat dissipation shell 5 and communicates with the conveying shell 6, the other end of the heat dissipation pipe 10 communicates with the conveying shell 6, the cooling assembly also includes a pressure pump 17, the pressure pump 17 is fixedly connected to the heat dissipation shell 5, the water outlet on one side of the pressure pump 17 is connected to the water delivery pipe 18, the surface of the support pipe 14 is connected to the nozzle 19, the other end of the water delivery pipe 18 is connected to the support box 13, the worm 12 One side is meshed with the worm gear 16, the top of the worm 12 passes through the interior of the conveying shell 6 and is fixedly connected to the second conveying gear 9, the surface of the support tube 14 is movably connected to the inner wall of the support box 13 through a bearing, and an exhaust pipe 20 is sleeved on the surface of the fan blade 15, one side of the exhaust pipe 20 is fixedly connected to the heat dissipation shell 5, the front side of the heat dissipation shell 5 is connected to the air inlet pipe 21, the inside of the air inlet pipe 21 is fixedly connected to a filter screen, the inside of the heat dissipation shell 5 is fixedly connected to a partition 22, and the water inlet on one side of the pressure pump 17 is connected to the partition 22 through a pipe.

[0035] Specifically: the heat dissipation pipe 10 is made of copper tube material. When the lubricating liquid enters the heat dissipation pipe 10, the heat can be discharged through the heat dissipation pipe 10 to increase the heat dissipation area. The fan blades 15 can rotate under the drive of the support tube 14.

When the fan blades 15 rotate, the hot air inside the heat dissipation shell 5 is discharged, thereby improving the heat dissipation effect on the heat dissipation tube 10. At the same time, the pressure pump 17 is started, and the pressure pump 17 draws the water inside the heat dissipation shell 5 into the support box 13, and then discharges it into the support tube 14, and sprays the water to the heat dissipation tube 10 through the nozzle 19.
