Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling cooling equipment, in particular to a walking cooling bed movable beam translation wheel mechanism. Background Art

[0002] The medium and thick plate walking cooling bed in the medium plate production line of the steel plant is currently used to cool the hot steel plates naturally, that is, the steel plates are gradually cooled during the slow movement process, and the movable beam and the lifting beam in the cooling bed body structure cooperate to lift and move the steel plates horizontally, and then transport them to the next location in steps. Among them, the horizontal movement of the cooling bed is achieved by driving the movable beam through the transmission mechanism. During the stepping process, the movable beam translation wheel bears the load of the cooling bed movable beam and the steel plate, and is the weak part of the cooling bed structure. In addition, due to the relatively complex structure of the translation wheel trolley assembly, when the translation wheel needs to be replaced online, the entire translation wheel trolley assembly needs to be removed from under the movable beam, which is difficult to operate, time-consuming, labor-intensive and inefficient. Therefore, there is an urgent need for a translation wheel mechanism with strong load-bearing capacity and convenient replacement, which can improve the overall strength of the movable beam translation wheel mechanism while simplifying the inspection and maintenance of the translation wheel mechanism. Utility Model Content

[0003] The utility model aims to provide a stepping cooling bed movable beam translation wheel mechanism, which can solve the problems of the prior art in that the operation is difficult and time-consuming when replacing the translation wheel.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: this walking cooling bed movable beam translation wheel mechanism includes a translation wheel body and a translation wheel, and there are two translation wheels, which are arranged side by side under the translation wheel body along the length of the translation wheel body, and the bottom ends of the two side panels of the translation wheel body are respectively provided with two groups of downward-opening mounting grooves, and the two ends of the wheel axle of the translation wheel are respectively extended into the mounting grooves, and the opening of the mounting groove is closed with a pressure plate, and the pressure plate is fastened to the translation wheel body by fasteners.

[0005] In the technical solution of the above-mentioned walking cooling bed movable beam translation wheel mechanism, a more specific technical solution can also be: the translation wheel body includes a support plate at the top and the enclosures on both sides, the support plate and the enclosure are fixed by welding, and a plurality of reinforcement blocks are provided on the outside of the enclosure, the inner side of the reinforcement block is welded to the enclosure, and the top is welded to the bottom of the support plate.

[0006] In some possible implementation schemes, a plurality of threaded holes for threaded connection with the movable beam are symmetrically provided on the support plate of the translation wheel vehicle body.

[0007] In some possible implementations, each translation wheel is equipped with a bearing, the wheel axle passes through the bearing, and the diameter of the wheel axle section installed in the bearing is larger than the diameter of the wheel axle section installed in the mounting groove.

[0008] In some possible implementation schemes, the fasteners used to fasten the pressure plate and the translation wheel body are fastening bolts.

[0009] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0010] 1. Since the bottom ends of the panels on both sides of the translation wheel body are respectively provided with two groups of downward-opening mounting grooves, the two ends of the translation wheel axle are respectively extended into the mounting grooves, and the openings of the mounting grooves are screwed together with pressure plates. When replacing the translation wheel, there is no need to disassemble the entire translation wheel mechanism from the movable beam. You only need to unscrew the fasteners that fasten the pressure plates, lift the movable beam to a certain height, and remove the translation wheel axle from the mounting groove opening. The entire translation wheel and axle can be taken out from the bottom of the translation wheel body. The operation is easy and time-saving, which greatly reduces the labor intensity of the workers and improves the work efficiency of replacing the translation wheel.

[0011] 2. Since there are two translation wheels in the translation wheel body, which are arranged side by side under the translation wheel body along the length of the translation wheel body, the problem of insufficient bearing capacity of the translation wheel mechanism of the movable beam of the walking cooling bed is solved, and the bearing capacity of the translation wheel mechanism is further improved.

The pressing plate is fastened to the enclosure 1-1 of the translation wheel body 1 by fastening bolts 5. When the translation wheel is installed under the translation wheel body, the pressing plate is removed, and the two ends of the wheel axle of the translation wheel are removed from The mounting notch is inserted into the mounting groove 3 upwards, and the pressure plate 4 is then closed on the mounting notch to enclose the wheel axle in the mounting groove, and the pressure plate is fixed to the bottom end of the enclosure with the fastening bolts; when the translation wheel needs to be replaced, there is no need to disassemble the entire translation wheel mechanism from the movable beam. Just unscrew the fasteners that fasten the pressure plate, lift the movable beam to a certain height, and remove the wheel axle of the translation wheel from the opening of the mounting groove.
