It includes a rolling mill cooling bed, a base, a power mechanism and a transmission shaft, the power mechanism is installed on the base, the base is also provided with a support seat, the support seat is provided with a stepping control seat, the rolling mill cooling bed is arranged on the support seat, a movable tooth beam is hinged on the rolling mill cooling bed, a stepping control wheel adapted to the stepping control seat is fixedly connected to the bottom of the movable tooth beam, and a transmission rod is connected to the power mechanism for transmission, and the transmission rod is hinged to the movable tooth beam through a first transmission arm, a transmission shaft, a second transmission arm, a first connecting rod, a first sliding rod, a first arc-shaped slide base, a second connecting rod, a second sliding rod, and a second arc-shaped slide base.

[0004] Existing steel rolling cooling beds such as the above are mostly composed of a fixed rack, a movable rack and a driving mechanism of the movable rack. The driving mechanism drives the movable rack to swing periodically along a specified path, so that the steel rolling moves step by step, and the steel rolling is cooled in this process. In the specific implementation process, when the steel rolling moves, the area in contact with the movable rack and the fixed rack is relatively fixed, and the contact process will affect the heat dissipation of the area, thereby affecting the uniformity of the overall heat dissipation of the steel rolling. Therefore, it is urgent to propose a corresponding new type of steel rolling cooling bed equipment to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to propose a new type of steel rolling cooling bed in order to solve the above problems.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A novel steel rolling cooling bed comprises a transmission cooling bed, which comprises a frame, a fixed rack and a movable rack. Both sides of the horizontal end of the frame are fixedly connected to side seats. The tops of the two groups of side seats are integrated with linkage plates and pushing components for pushing the linkage plates. The opposite surfaces of the two groups of linkage plates are respectively fixedly connected with multiple groups of left-side shifting blocks and right-side shifting blocks, and the multiple groups of left-side shifting blocks and right-side shifting blocks are staggered.

[0008] Preferably, the bottoms of the two groups of side seats are fixedly connected to a base frame, and the base frame is fixedly connected to the frame via a locking rod.

[0009] Preferably, the pushing assembly includes a pushing member fixedly connected to the side seat, and an output end of the pushing member is fixedly connected to the linkage plate.

[0010] Preferably, the cross-sections of the two groups of side seats are both U-shaped structures, and the multiple groups of left-side displacement blocks and right-side displacement blocks are respectively slidably connected to the inner surface walls of the vertical ends of the two groups of side seats.

[0011] Preferably, the open ends of the multiple groups of left-side shifting blocks and right-side shifting blocks are all snap-connected with balls.

[0012] Preferably, the inner surface wall of the side seat is fixedly connected with a fixing strip, the outer surface wall of the linkage plate is fixedly connected with a sliding sleeve, and the inner surface wall of the sliding sleeve is slidably connected with the inner surface wall of the fixing strip.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present application, multiple groups of left-side shift blocks and right-side shift blocks are staggered, and the spacing between adjacent left-side shift blocks and right-side shift blocks is the same as the spacing between the tooth grooves on the fixed rack. After the rolled steel falls into the initial position of the fixed rack and the movable rack, one group of pushers and the linkage plate cooperate to drive the left-side shift block to move, and the left-side shift block drives the rolled steel to translate a corresponding distance. Then the movable rack transfers the rolled steel to the next tooth groove of the fixed rack, and another group of pushers and the linkage plate cooperate to drive the right-side shift block to move, and the right-side shift block drives the rolled steel to reset horizontally. This reciprocating process makes the contact position of the rolled steel with the fixed rack and the movable rack dynamically change during the transfer process, thereby improving the uniformity of heat dissipation in various areas of the rolled steel.

[0015] 2. In the present application, the bottom of the two groups of side seats are fixed with a base frame, and the two groups of base frames are fixed to the frame by locking rods, thereby ensuring the stable position of the two groups of side seats. At the same time, the two groups of side seats can be conveniently disassembled and assembled according to usage requirements, thereby improving the convenience of using the new steel rolling cooling bed equipment.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4 , the present invention provides a technical solution:

[0023] A novel steel rolling cooling bed comprises a transmission cooling bed 1, the transmission cooling bed 1 comprises a frame 101, a fixed rack 102 and a movable rack 103, both sides of the horizontal end of the frame 101 are fixedly connected to side seats 2, the tops of the two groups of side seats 2 are integrated with linkage plates 8 and a pushing component for pushing the linkage plates 8, the opposite surfaces of the two groups of linkage plates 8 are respectively fixedly connected with a plurality of left-side shifting blocks 3 and a right-side shifting blocks 4, and the plurality of left-side shifting blocks 3 and the right-side shifting blocks 4 are staggeredly distributed;

[0024] A plurality of groups of left-side shifting blocks 3 and right-side shifting blocks 4 are staggered, and the spacing between adjacent left-side shifting blocks 3 and right-side shifting blocks 4 is the same as the spacing between the tooth grooves on the fixed rack 102. After the rolled steel falls into the initial position of the fixed rack 102 and the movable rack 103, one group of pushing members 5 cooperates with the linkage plate 8 to drive the left-side shifting block 3 to move, and the left-side shifting block 3 drives the rolled steel to translate a corresponding distance, and then the movable rack 103 transfers the rolled steel to the next tooth groove of the fixed rack 102, and another group of pushing members 5 cooperates with the linkage plate 8 to drive the right-side shifting block 4 to move, and the right-side shifting block 4 drives the rolled steel to be horizontally reset, and so on. In this reciprocating manner, the contact position of the rolled steel with the fixed rack 102 and the movable rack 103 changes dynamically during the transfer process, thereby improving the uniformity of heat dissipation in various areas of the rolled steel.

[0025] Preferably, Figure 2 and Figure 4 As shown, the bottom of the two groups of side seats 2 are fixedly connected with the base frame 6, and the base frame 6 is fixedly connected to the frame 101 through the locking rod 7. The base frame 6 is fixed to the bottom of the two groups of side seats 2, and the two groups of base frames 6 are fixed to the frame 101 through the locking rod 7, thereby ensuring the stable position of the two groups of side seats 2. At the same time, the two groups of side seats 2 can be conveniently disassembled and assembled according to usage requirements, thereby improving the convenience of using the new steel rolling cooling bed equipment.

[0026] Preferably, Figure 2 and Figure 3 As shown, the pushing component includes a pushing member 5 fixedly connected to the side seat 2, and the output end of the pushing member 5 is fixedly connected to the linkage plate 8. The pushing member 5 is used to simultaneously link multiple groups of shift blocks on the same side. The cross-sections of the two groups of side seats 2 are both U-shaped structures. Multiple groups of left-side shift blocks 3 and right-side shift blocks 4 are respectively slidably connected to the inner surface walls of the vertical ends of the two groups of side seats 2, thereby further ensuring the stability of the movement of multiple groups of left-side shift blocks 3 and right-side shift blocks 4. The open ends of multiple groups of left-side shift blocks 3 and right-side shift blocks 4 are all engaged and connected with balls 11 to reduce the friction between the shift blocks and the rolled steel. The inner surface wall of the side seat 2 is fixedly connected to a fixing strip 9, and the outer surface wall of the linkage plate 8 is fixedly connected to a sliding sleeve 10, and the inner surface wall of the sliding sleeve 10 is slidably connected to the inner surface wall of the fixing strip 9, thereby further ensuring the stability of the movement of the linkage plate 8.

[0027] The working principle of the present invention is as follows: a plurality of groups of left-side shifting blocks 3 and right-side shifting blocks 4 are staggered and distributed, and the spacing between adjacent left-side shifting blocks 3 and right-side shifting blocks 4 is the same as the spacing between the tooth grooves on the fixed rack 102. After the rolled steel falls into the initial position of the fixed rack 102 and the movable rack 103, one group of pushing members 5 cooperates with the linkage plate 8 to drive the left-side shifting block 3 to move, and the left-side shifting block 3 drives the rolled steel to translate a corresponding distance. Then the movable rack 103 transfers the rolled steel to the next tooth groove of the fixed rack 102, and another group of pushing members 5 cooperates with the linkage plate 8 to drive the right-side shifting block 3 to move. The shift block 4 moves, and the right shift block 4 drives the rolled steel to be horizontally reset, and so on, so that during the transfer process of the rolled steel, its contact position with the fixed rack 102 and the movable rack 103 is dynamically changed, thereby improving the uniformity of heat dissipation in various areas of the rolled steel. The bottom of the two groups of side seats 2 are fixed with the base frame 6, and the two groups of base frames 6 are fixed to the frame 101 by the locking rod 7, thereby ensuring the position stability of the two groups of side seats 2. At the same time, the two groups of side seats 2 can be conveniently disassembled and assembled according to the use requirements, thereby improving the convenience of using the new rolled steel cooling bed equipment.
