[0028] Example:

[0029] Reference Figures 1 to 6 This embodiment proposes a device for cooling a bearing steel tube after hot rolling, which mainly includes a cooling box 1 and a support assembly 7; one side of the support assembly 7 is rotatably mounted on the top of the inner cavity of the cooling box 1, and a driving structure is provided at the bottom of the support assembly 7, and the driving structure is fixed to the inner wall of the cooling box 1. The driving structure is suitable for driving the bottom of the support assembly 7 to move upward, so that the support assembly 7 rotates around the side on which it is rotatably mounted, so that the support assembly 7 forms a discharge port on the side on which it is rotatably mounted. Through the driving structure provided in this embodiment, the driving structure can allow one side of the support assembly 7 to move upward as a whole, and since the rotatably mounted side is not necessarily moved upward when one side moves upward, the support assembly 7 will rotate around the rotatably mounted side, thereby Figure 2 form Figure 3 status, Figure 3 If the left side of the support assembly 7 continues to rise, the inclination will be greater, so the pipe 6 can be Figure 3 The material is discharged on the right side. After the unloading is completed, the driving structure causes the support assembly 7 to reset downward, and the support assembly 7 can be restored to its original state. This embodiment realizes the automatic unloading of the pipe 6. The driving structure only needs to realize the rotation and unloading of the support assembly 7 through the up and down strokes. The realization principle is simple, the equipment manufacturing difficulty is small, the cost is low, and no additional production space is occupied. It is suitable for cooling and automatic unloading of pipes 6 such as bearing steel pipes.

[0030] like Figure 2 , Figure 3 The support assembly 7 includes a support portion 75 with a through hole 12 and a pair of stoppers 71 respectively arranged at the top of both sides of the support portion 75. The support portion 75 and the stoppers 71 form a material receiving space that is open upward. The through hole 12 on the support portion 75 is to facilitate the coolant inside the cooling box 1 to pass through the through hole 12 and contact the pipe 6 unimpeded for cooling when the pipe 6 is placed on the support portion 75. Figure 2 As shown, the limiting portion 71 on one side is provided with a shaft portion 4. The limiting portion 71 on the right side of the figure is provided with a shaft portion 4. The shaft portion 4 can be just a shaft, or it can be as shown in FIG. Figure 2As shown, a coiled sleeve is formed at the top of the limit portion 71, and then a rotating shaft is set to pass through the shaft portion 4. The shaft portion 4 is provided with mounting portions 2 on the inner walls on both sides of the cooling box 1 perpendicular to the direction of the limit portion 71. The mounting portions 2 limit the shaft portion 4 to slide up and down within its mounting range, and the mounting portions 2 do not limit the rotation of the shaft portion 4; Figure 1 and Figure 3 As shown, the mounting portion 2 has a mounting groove 21, and the shaft portion 4 is limited to move up and down within the range of the mounting groove 21; the inner walls of the opposite sides of the cooling box 1 are both installed with guide portions 8, and the guide portions 8 are suitable for limiting the movement of the support portion 75 in the up and down directions. Obviously, if only the support portion 75 is installed by rotation, the bottom of the support portion 75 may not reach a deeper position in the cooling box 1; for this reason, the present embodiment is provided with a guide portion 8 and a mounting portion 2 of the shaft portion 4, and it is obvious that the support portion 75 can move up and down within the guide range of the guide portion 8, and the shaft portion 4 moves up and down in the mounting groove 21 of the mounting portion 2. When the shaft portion 4 moves to the top of the mounting groove 21, the limiting portion 71 leaves the limiting position of the guide portion 8. When the driving structure continues to drive the support portion 75 on the left side to rise, since there is no longer a limiting position of the guide portion 8, the support portion 75 will rotate around the shaft portion 4 at this time, and then discharge the material. That is, when the limiter 71 is still within the limit range of the guide 8, the driving structure only drives the support 75 to move up and down, and when the limiter 71 rises and breaks away from the limit of the guide 8, the driving structure continues to drive, and the support 75 will rotate to discharge the material. In this way, when the pipe 6 is cooled, the pipe 6 can reach a deeper position in the cooling box 1, thereby obtaining a better cooling effect.

[0031] like Figures 2 to 4 , an action block 72 is provided at the bottom of the side of the support part 75 away from the shaft part 4, a connecting rod 73 is hinged at the bottom of the action block 72, a slider 74 is hinged at the bottom of the connecting rod 73, a screw rod 9 is provided for cooperation with the slider 74, the screw rod 9 is installed on the inner wall of the cooling box 1, the screw rod 9, the slider 74, the connecting rod 73 and the action block 72 together form a driving structure, the screw rod 9 drives the slider 74 to move up and down, thereby causing the support part 75 to move. This embodiment is a preferred embodiment of the driving structure. Obviously, when the screw rod 9 drives the slider 74 upward (the principle of the screw rod 9 slide is not repeated), the slider 74 rises to drive the connecting rod 73 to rise, and both ends of the connecting rod 73 are hinged. When the action block 72 connected to the top of the connecting rod 73 rises, due to the limitation of the right side shaft part 4 of the support part 75, the action block 72 rotates together with the support part 75, thereby realizing the discharge, and when the screw rod 9 drives the slider 74 to return downward, the support part 75 is reset.

[0032] Further, in this embodiment, a pair of action blocks 72 are provided, a first action rod 77 is fixedly installed between the pair of action blocks 72, a pair of connecting rods 73 are provided, and the top end is hinged to the first action rod 77; a second action rod 7 is fixedly installed on the outer side of the slider 74, and the second action rod 7 is hingedly connected to the bottom of the pair of connecting rods 73. When the action blocks 72, the first action rod 77 and the second action rod 7 are added, the principle is the same, but it is equivalent to strengthening the drive structure. The pipe fittings 6 such as steel pipes have a higher initial temperature. The setting of this embodiment can effectively reduce the pressure on each component, thereby increasing the service life.

[0033] like Figure 1 As shown, a avoidance groove 3 is provided on the top of one side of the cooling box 1. When the support assembly 7 rotates to discharge materials, at least a part of the limiting portion 71 on the same side as the avoidance groove 3 is located in the avoidance groove 3. The avoidance groove 3 is provided to facilitate the support portion 75 to discharge materials. If the avoidance groove 3 is not provided, the position where the support portion 75 is installed on the shaft portion 4 needs to be at the top of the cooling box 1, otherwise the inner wall of the cooling box 1 will prevent the pipe 6 from falling out.

[0034] Preferably, the bottom of the support portion 75 is arc-shaped or V-shaped; compared to a flat bottom, the arc-shaped and V-shaped bottom can make the depth of the bottom in the cooling box 1 deeper, and at the same time increase the range of space for accommodating the pipe 6.

[0035] like Figure 1 As shown, a material discharge portion 5 is provided on the outside of the cooling box body 1 on one side where the support assembly 7 is rotatably installed. The material discharge portion 5 is tilted downward to facilitate material discharge.

[0036] like Figure 4 , Figure 5 A filter plate 11 is provided at the bottom of the cooling box 1, and at least one pair of positioning posts 10 are provided on the bottom surface of the cooling box 1. The filter plate 11 is inserted on the pair of positioning posts 10, so as to facilitate the installation of the filter plate 11. An avoidance hole 13 suitable for the screw rod 9 to pass through is opened at the edge of the filter plate 11.

[0037] like Figure 2 , Figure 3 As shown, the guide portion 8 includes a vertical limiting portion at the top and an arc-shaped limiting portion at the bottom. The arc-shaped limiting portion forms the lowest position for limiting the downward movement of the support assembly 7. When the bottom of the support portion 75 abuts against the arc-shaped limiting portion 71, it reaches the lowest end of its downward movement. The limiting portion 71 cooperates with the vertical limiting portion 71 to limit.
