DETAILED DESCRIPTION

[0016] like Figure 1-6 As shown: a temperature regulating device of a hydraulic station of a hoist, comprising a hydraulic station 1; a winding drum 2 is provided on the left side of the hydraulic station 1, the right side wall of the winding drum 2 is open, a winding shaft 3 is rotatably connected between the inner top wall and the inner bottom wall of the winding drum 2, an electric blanket 4 is wound on the outer wall of the winding shaft 3, the inner end of the electric blanket 4 is fixedly connected to the winding shaft 3, the outer end of the electric blanket 4 is wound around the outer wall of the winding shaft 3 and passes through the right side opening of the winding drum 2, the electric blanket 4 extends along the outer wall of the hydraulic station 1, a magnet 5 is fixedly connected to the top of the outer end of the electric blanket 4, the magnet 5 is magnetically attracted to the outer shell of the hydraulic station 1, the bottom end of the winding shaft 3 passes through the bottom of the winding drum 2 and is fixedly connected to a bevel gear 1 6, a fixed seat 7 is fixedly connected to the bottom left side of the winding drum 2, a rotating shaft 8 is rotatably connected to the bottom of the fixed seat 7, the right end of the rotating shaft 8 is fixedly connected to a bevel gear 2 9, the bevel gear 2 9 is meshed with the bevel gear 1 6, and the left end of the rotating shaft 8 is fixedly connected to a crank 10.

[0017] The electric blanket 4 comprises a heating wire 41 , an inner protective layer 42 and a heat-insulating layer 43 . The inner protective layer 42 is fixed to the inner wall of the heating wire 41 , and the heat-insulating layer 43 is fixed to the outer wall of the heating wire 41 . The heating wire 41 is between the inner protective layer 42 and the heat-insulating layer 43 .

[0018] The electric blanket 4 is wound on the winding shaft 3 and stored in the winding drum 2. The outer end of the electric blanket 4 extends out through the right opening of the winding drum 2 and extends along the outer wall of the hydraulic station 1. The magnet 5 on the top is adsorbed on the top of the outer shell of the hydraulic station 1 to ensure the fixed position of the electric blanket 4. At this time, the electric blanket 4 is in a non-working state and does not generate heat.

[0019] When the temperature of the hydraulic station 1 needs to be adjusted, first rotate the crank 10, which drives the rotating shaft 8 to rotate. Since the right end of the rotating shaft 8 is fixedly connected with the bevel gear 2 9, and the bevel gear 2 9 is meshed with the bevel gear 1 6 at the bottom end of the winding shaft 3, the rotation of the rotating shaft 8 will drive the winding shaft 3 to rotate.

[0020] As the reel 3 rotates, the electric blanket 4 originally wound on the reel 3 begins to gradually unfold and continues to extend along the outer wall of the hydraulic station 1. The unfolding length of the electric blanket 4 can be adjusted as needed and controlled by continuing to rotate the crank 10.

[0021] When the electric blanket 4 completely or partially covers the oil tank of the hydraulic station 1 or other parts that need to be heated, the power of the electric blanket 4 is turned on, and the heating wire 41 starts to heat up. Since the heating wire 41 is wrapped by the inner protective layer 42 and the insulation layer 43, the heat can be effectively transferred to the oil tank, while reducing heat loss and improving heating efficiency.

[0022] By controlling the heating time and power of the electric blanket 4, the temperature of the hydraulic station 1 can be accurately adjusted. When the required temperature is reached, the power of the electric blanket 4 can be turned off, or the heating effect can be controlled by adjusting the coverage area of ​​the electric blanket 4.

[0023] When not in use, the crank 10 is rotated in the reverse direction, the reel 3 winds up the electric blanket 4, and the electric blanket 4 is stored in the reel 2. The utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the utility model.
