[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0018] according to Figure 1 , 2As shown in Figure 3, this embodiment proposes a ductile iron manhole cover cooling device, including a liquid storage tank 1, a cooling tank 2 and a fixing frame 3. The cooling tank 2 is provided on the right side of the liquid storage tank 1, and the fixing frame 3 is provided on the left side of the liquid storage tank 1. A spraying mechanism is provided above the fixing frame 3, and a supporting frame 4 is provided on the outer side of the cooling tank 2. A lifting mechanism is provided on the top of the supporting frame 4. The manhole cover mold is placed on the top of the fixing frame 3 by a transport forklift. The spraying mechanism will receive the water inside the liquid storage tank 1 and spray it to the manhole cover mold to rinse the sand on the surface of the manhole cover mold. After that, the transport forklift lifts the manhole cover mold and moves the manhole cover mold to the top of the cooling tank 2, and then connects the lifting mechanism to the manhole cover mold, and uses the lifting mechanism to drive the manhole cover mold to move downward, so that the manhole cover mold is immersed in the coolant inside the cooling tank 2 to cool the manhole cover in the mold. Finally, the lifting mechanism drives the manhole cover to move upward, releases the connection with the manhole cover, and transports it out by a transport forklift.

[0019] The spray washing mechanism includes a water pump 7, a liquid infusion pipe 8, a spray pipe 9 and a nozzle 10. The water pump 7 is installed on the outside of the liquid reservoir 1, and the spray pipe 9 is symmetrically arranged on the left side of the liquid reservoir 1. The output end of the water pump 7 is connected to the inner side of the spray pipe 9 through the liquid infusion pipe 8, and the input end of the water pump 7 is connected to the inside of the liquid reservoir 1 through the liquid infusion pipe 8. The top of the spray pipe 9 is connected to multiple nozzles 10. The fixing frame 3 is composed of a support rod and a limiting ring. The limiting ring is welded to the top of the support rod. A plurality of racks 11 are also provided at the top of the support rod. After the manhole cover mold is placed on the top of the fixed frame 3, the racks 11 at the top support the manhole cover mold, and at this time the manhole cover mold is facing the spray direction of the nozzle 10. The water pump 7 cooperates with the infusion pipe 8 to transport the cold water inside the liquid storage tank 1 to the inside of the spray pipe 9. The spray pipe 9 sprays the cold water to the manhole cover mold through the nozzle 10 to automatically wash the sand on the surface of the manhole cover mold. The nozzle 10 is of a diffusive type and can cover the entire manhole cover mold.

[0020] The hook 15 is composed of a connecting seat, a fixed hook and a movable hook. The fixed hook is fixedly connected to the bottom of the connecting seat. The top of the connecting seat is fixedly connected to the bottom end of the wire rope 14. The bottom end of the fixed hook is hinged with a movable hook through a pin shaft, and a torsion spring is provided on the outside of the pin shaft. The movable hook is bent and rotated outward to hook the chain surrounding the manhole cover mold on the inside of the fixed hook. Then, the elastic force of the torsion spring is used to drive the movable hook to rotate inward and reset it to connect the manhole cover mold with the hook 15. When disassembling, it is only necessary to rotate the movable hook outward again.

[0021] The hoisting mechanism includes a rotating roller 13, a wire rope 14, a hook 15 and a motor 16. The top of the support frame 4 is rotatably installed with a rotating roller 13, the outer side of the rotating roller 13 is wound with a wire rope 14, the bottom end of the wire rope 14 is connected with a hook 15, and the top of the support frame 4 is installed with a motor 16. The output end of the motor 16 is connected to one end of the rotating roller 13, and the motor 16 can drive the rotating roller 13 to rotate clockwise or counterclockwise on the top of the support frame 4. When the rotating roller 13 rotates clockwise, the wire rope 14 on its outer side can be released, so that the wire rope 14 drives the hook 15 to move downward, and then the hook 15 drives the manhole cover mold to move downward into the coolant inside the cooling tank 2. When the rotating roller 13 rotates counterclockwise, the wire rope 14 at the bottom end of its outer side can be reeled in, so that the wire rope 14 drives the hook 15 to move upward, and then after the cooling work is completed, the hook 15 drives the manhole cover mold to move upward and out of the coolant.

[0022] An opening is provided on the left side of the top of the liquid storage tank 1, and a filter screen 12 is engaged with the opening and the bottom of the cooling tank 2, and the position of the opening is vertically parallel to the position of the fixing frame 3. The filter screen 12 on the opening intercepts the sand under flushing to prevent the sand from entering the interior of the liquid storage tank 1 through the opening, and the filter screen 12 at the bottom of the cooling tank 2 intercepts the iron slag generated after the mold is heated and cooled to prevent it from sticking to the bottom of the cooling tank 2 and being difficult to clean, and the two filter screens 12 are both engaged and connected, which is convenient for disassembly and cleaning.

[0023] The cooling tank 2 is equipped with a liquid pump and a liquid extraction pipe. A liquid injection tank 5 is provided on the right side of the liquid storage tank 1. The top of the liquid injection tank 5 is threadedly connected to an end cap. The left side of the liquid storage tank 1 is connected to a liquid discharge pipe 6. The end cap at the top of the liquid injection tank 5 is unscrewed to replenish water into the liquid storage tank 1 through the liquid injection tank 5. The remaining cold water can be discharged to the outside of the liquid storage tank 1 through the liquid discharge pipe 6. The used coolant in the cooling tank 2 can be extracted from the cooling tank 2 through the liquid pump and the liquid extraction pipe.

[0024] The ductile iron manhole cover cooling equipment places the manhole cover mold on the top of the fixed frame 3, and the frame rod 11 on the top supports the manhole cover mold. At this time, the manhole cover mold is facing the spray direction of the nozzle 10. The water pump 7 and the infusion pipe 8 cooperate to transport the cold water inside the liquid storage tank 1 to the inside of the spray pipe 9. The spray pipe 9 sprays the cold water to the manhole cover mold through the nozzle 10. The nozzle 10 is diffusive and can cover the entire manhole cover mold to automatically wash the sand on the surface of the manhole cover mold, so as to solve the problem of low efficiency of manual washing of the sand on the mold surface in the prior art, which affects the cooling efficiency of the ductile iron manhole cover.
