DETAILED DESCRIPTION

[0023] In order to solve the problem of inconsistent cooling rate and large deformation of frog steel caused by solid solution strengthening of frog steel in batch stacking, the utility model provides a frog steel circulating immersion platform. The frog steel circulating immersion platform is further described below with specific embodiments combined with the accompanying drawings.

[0024] See also Figures 1 to 4As shown, a frog steel circulating immersion platform comprises a U-shaped rotating frame 2, a driving mechanism 4 and a liquid supply pipeline 6. The U-shaped rotating frame 2 is rotatably mounted on a water tank 1 and realizes circulating immersion in the water tank 1 through rotational movement. A frog steel processing device 3 based on liquid supply is fixed on the U-shaped rotating frame 2. The U-shaped rotating frame 2 comprises a support plate 21 adapted to the opening 11 of the water tank 1 and two end plates 22 fixed at both ends of the support plate 21. The two end plates 22 extend into the water tank 1 and are respectively adjacent to the two side walls 12 of the water tank. The number of the driving mechanisms 4 is two, which are respectively used to drive the two end plates 22 to rotate synchronously to drive the support plate 21 to rotate. The two side walls 12 of the water tank 1 are respectively provided with installation openings. The two driving mechanisms 4 are respectively installed at the two installation openings and are connected to the adjacent end plates 22 in an eccentric transmission manner through a transmission mechanism 5. The liquid supply pipeline 6 is used to supply liquid to the frog steel processing equipment 3 to maintain the frog steel processing equipment 3 to work, and includes a Z-shaped main pipe 61 and a branch pipe 62 connected to the Z-shaped main pipe 61 and used to connect to the frog steel processing equipment 3. The number of the branch pipes 62 can be multiple, and the specific number and distribution of the branch pipes 62 are determined by the specific structure of the frog steel processing equipment 3. The Z-shaped main pipe 61 includes a belly pipe section that passes through and is fixed to the base plate 21, an upper flange pipe section located above the base plate 21 and connected to the branch pipe 62, and a lower flange pipe section located below the base plate 21. A first through hole 221 is provided at the rotation center of the end plate 22, and the lower flange pipe section passes through the first through hole and is inserted into the installation port on the corresponding side.

[0025] Regarding the structure of the drive mechanism 4 realizing eccentric transmission through the transmission mechanism 5, see Figure 3As shown: the driving mechanism 4 includes a driving motor 41 and a driving mechanism cover 44 for covering the outside of the driving motor 41 and fixed to the water tank 1, the side of the driving mechanism cover 44 facing the water tank 1 is formed as the sealing plate 42, the sealing plate 42 is sealed and fixed at the installation port, the driving motor 41 is fixed to the outside of the sealing plate 42, and a second through hole 421 for connecting the lower flange pipe section with the outside of the water tank 1 is opened on the sealing plate 42 at a position corresponding to the lower flange pipe section, specifically, a shaft sleeve 222 is fixed in the first through hole 221, the lower flange pipe section is plugged and fixed in the shaft sleeve 222, and the end of the shaft sleeve 222 facing the sealing plate 42 extends toward the direction of the second through hole 421 and forms an extension section. A swivel joint 45 for liquid inlet is connected to the position of the sealing plate 42 corresponding to the second through hole 421, and the swivel joint 45 includes a fixed part 451 and a rotating part 452 rotatably connected to the fixed part 451. The fixed part 451 is fixed to the outer side of the sealing plate 42 and forms a liquid inlet for connecting to an external liquid supply device. The rotating part 452 forms a liquid inlet channel 4521 that is connected to the liquid inlet. The rotating part 452 passes through the second through hole 421 and is inserted into the extension section of the sleeve 222. The lower flange pipe section is connected to the swivel joint 45 through the sleeve 222. When the end plate 22 rotates, the lower flange pipe section, the sleeve 222 and the rotating part 452 of the swivel joint 45 rotate synchronously with the end plate 22, while the fixed part 451 of the swivel joint 45 is fixed. The swivel joint 45 and the drive motor 41 are both covered in the drive mechanism cover 44 . To improve the rotation effect of the U-shaped rotating frame 2 , the drive mechanism 41 may further include other components such as a reducer, which are all covered together in the drive mechanism cover 44 .

[0026] The sealing plate 42 is provided with an axial hole 422 for the motor shaft of the driving motor 41 to pass through at a position avoiding the second through hole 421. The transmission mechanism 5 includes a driving gear 51 and a gear ring 52 which are sandwiched side by side between the end plate 22 and the sealing plate 42. The driving gear 51 is sleeved and fixed on one end of the motor shaft passing through the axial hole 422. The outer periphery of the gear ring 52 is provided with teeth. The driving gear 51 meshes with the outer peripheral teeth of the gear ring 52. The gear ring 52 is fixed to the outer side of the end plate 22. A support ring 43 extending into the gear ring 52 is fixed to the inner side of the sealing plate 42 (i.e., the side facing the water tank 1). The outer periphery of the support ring 43 fits with the inner periphery of the gear ring 52. The gear ring 52 is supported by the support ring 43 without affecting the rotation of the gear ring 52 relative to the support ring 43.

[0027] When the driving motor 41 rotates, the motor shaft drives the driving gear 51 to rotate, and the driving gear 51 drives the gear ring 52 to rotate, thereby driving the end plate 22 and even the U-shaped rotating frame 2 to rotate along the rotation axis L. Since the lower flange pipe section of the Z-shaped main pipe 61 is coaxial with the rotation axis L, when the Z-shaped main pipe 61 rotates with the U-shaped rotating frame 2, the lower flange pipe section rotates around the rotation axis L, and the belly pipe section, the upper flange pipe section and the branch pipes 62 swing with the rotation of the U-shaped rotating frame 2, but the relative positions of the various pipe sections of the liquid supply pipeline 6 do not change, thereby avoiding the phenomenon of winding of the liquid supply pipeline 6.

[0028] The frog steel processing equipment 3 can be any equipment that requires liquid supply, such as a clamping mechanism used to clamp and fix the frog steel to prevent the frog steel from falling when the platform flips. Usually, the clamping mechanism needs to use a driving part, such as a hydraulic cylinder, to achieve the clamping action. At this time, the supply of hydraulic oil is required to maintain the operation of the clamping mechanism. For example, a water spraying device needs water to work, and a hydraulic device needs hydraulic oil to maintain its operation. Based on the different types of liquid supply processing equipment 3, the liquids provided by the liquid supply pipeline are different. Of course, it is also possible that frog steel processing equipment 3 requiring different liquids are fixed on the base plate 21 at the same time. In order to enable the liquid supply pipeline 6 to simultaneously supply different liquids, the present embodiment uses the combination of the Z-shaped main pipe 61 and the branch pipe 62 as a protective pipe, and then provides a liquid supply hose 63, so that the liquid supply hose is passed through the protective pipe, and passes through the protective pipe at both ends and is respectively used to connect to the liquid inlet channel 4521 of the swivel joint 45 and the frog steel processing equipment 3. The liquid supply hose includes hoses for respectively supplying different liquids, such as a water supply hose and an oil supply hose. All hoses are arranged side by side through the protective pipe, such as Figure 3 Correspondingly, two separate liquid inlet channels 4521 are correspondingly arranged in the rotary joint 45 to connect the water supply hose and the oil supply hose respectively.

[0029] This embodiment changes the method of batch stacking and hoisting into water as a whole to the method of platform flipping and circulating water immersion, which can realize independent immersion of a single frog steel, avoiding the problems of inconsistent cooling rate and large deformation of frog steel caused by solid solution strengthening in batch stacking. In addition, through the eccentric transmission of the drive mechanism and the structural design of the liquid supply pipeline passing through the rotation center of the end plate, the liquid supply pipeline can rotate with the rotation of the U-shaped rotating frame, and the execution of the liquid supply operation is not affected when the platform is flipped, and the liquid supply pipeline will not be entangled, which has high work efficiency.

[0030] The utility model is described in detail above in conjunction with the embodiments of the drawings. A person skilled in the art can make various variations of the utility model according to the above description. Therefore, some details in the embodiments should not constitute a limitation of the utility model, and the scope of protection of the utility model shall be defined by the scope of the attached claims.
