[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a billet hoisting device, including a hoisting device body 100, the hoisting device body 100 including a horizontal plate 101, a bidirectional lead screw 108 rotating inside the horizontal plate 101, movable slides 103 located at both ends of the bidirectional lead screw 108 inside the horizontal plate 101, a forward and reverse motor 102 fixed at the end of the bidirectional lead screw 108 on the surface of the horizontal plate 101, a main frame 105 welded and fixed to the lower surface of the movable slide 103, and a main frame 105 fixed at the middle position of the upper surface of the main frame 105. A cylinder 104 is fixed. Anti-slip clamps 107 are mounted on both ends of the lower surface of the main frame 105 via connecting shafts. A movable connecting seat 106 is fixed to the end of the cylinder 104, and the end of the movable connecting seat 106 is connected to the end of the anti-slip clamp 107 via a connecting shaft. The movement of the cylinder 104 drives the movable connecting seat 106 to rise, and when the movable connecting seat 106 rises, the bearings drive the two anti-slip clamps 107 to clamp and fix them inward to the side of the steel billet, facilitating hoisting. The hoisting device body 100 is also equipped with:

[0024] The scraping and cleaning mechanism includes a fixed mounting assembly located on the lower surface of the main frame 105 and on the surface of the cylinder 104. The inner surface of the fixed mounting assembly is provided with a scraping and cleaning component. When the hoisting device body 100 is hoisting a steel billet, if dirt is attached to the telescopic end of the cylinder 104, the scraping and cleaning mechanism can scrape and clean the telescopic end of the cylinder 104. The cleaning is convenient and not easily obstructed.

[0025] To facilitate the fixed installation of the scraper 1042 and the cleaning brush 1043 through the fixed installation assembly, and to facilitate fixed scraping and cleaning, in this embodiment, preferably, the fixed installation assembly includes a fixing ring 1041 disposed on the outer surface of the cylinder 104 at the bottom of the main frame 105. The top edge of the fixing ring 1041 is provided with a fixing screw 1044, and the top of the fixing ring 1041 is fixedly connected to the lower surface of the main frame 105 by the fixing screw 1044. The fixing ring 1041 can be fixedly installed by the fixing screw 1044, and the scraper 1042 and the cleaning brush 1043 can be installed after the fixing ring 1041 is fixedly installed.

[0026] In order to facilitate the removal and cleaning of impurities from the end extension surface of the cylinder 104 by means of a scraping and cleaning component, and to prevent obstruction during extension and retraction operations, in this embodiment, preferably, the scraping and cleaning component includes a cleaning brush 1043 fixedly mounted on one end of the inner surface of a fixing ring 1041 by screws, and a scraper 1042 fixed to the inner bottom edge of the fixing ring 1041 by screws. The inner surfaces of both the scraper 1042 and the cleaning brush 1043 are in contact with the outer surface of the cylinder 104. This allows the end extension surface of the cylinder 104 to be scraped by the scraper 1042 and then cleaned again by the cleaning brush 1043 during use of the hoisting device body 100, which is convenient for scraping and cleaning and allows for smooth adjustment.

[0027] The stabilizing support mechanism includes fixed support components at both ends of the bottom of the movable slide 103. The top of the fixed support components is provided with a sliding connection component, and the top sides of the movable slide 103 are provided with rolling components. When the main body 100 of the hoisting device is hoisted, the movable slide 103 is moved and stabilized by the stabilizing support mechanism, which strengthens the support and makes the hoisting more stable.

[0028] In order to facilitate stable support operation of the movable slide 103 by means of a fixed support assembly, in this embodiment, preferably, the fixed support assembly is fixedly installed on the reinforcing support plates 1032 at both ends of the bottom of the movable slide 103 by bolts. The inner side of the reinforcing support plate 1032 is integrally provided with a side support plate 1033, and the end of the side support plate 1033 is fixed to the side of the movable slide 103 by fixing bolts. The movable slide 103 is stably supported and moved along with the reinforcing support plate 1032 and the side support plate 1033, so that the movable slide 103 is stably supported and hoisted for use.

[0029] In order to facilitate the movement and support of the reinforcing support plate 1032 and the side support plate 1033 by means of a sliding connection assembly, in this embodiment, preferably, the sliding connection assembly includes a sliding groove 1034 formed on both sides of the lower surface of the horizontal plate 101, and a slider 1035 is integrally provided on the top of the reinforcing support plate 1032, and the slider 1035 is slidably connected to the inside of the sliding groove 1034, so that when the movable slide 103 moves, it can drive the reinforcing support plate 1032 and the side support plate 1033 to move along with it, while providing side support, resulting in a more stable hoisting operation.

[0030] In order to facilitate smooth sliding adjustment of the movable slide block 103 inside the horizontal plate 101 through the rolling assembly, and to make it less likely to be obstructed and to be effectively adjusted and used, in this embodiment, preferably, the rolling assembly includes guide rollers 1031 that are rolled on both sides of the top of the movable slide block 103, and the outer surface of the guide rollers 1031 contacts the inner bottom end of the horizontal plate 101. When the movable slide block 103 slides inside the horizontal plate 101 on the outer surface of the bidirectional lead screw 108, the guide rollers 1031 are in contact with the inner bottom end of the horizontal plate 101 and slide smoothly, so as not to cause movement obstruction.

[0031] The working principle and usage process of this utility model are as follows: When using this billet hoisting device, the main body 100 of the hoisting device is first fixedly installed on the end of the wire rope connected to the winch on the external hoisting gantry frame by fixing the ear plates at both ends of the upper surface of the horizontal plate 101. After the main body 100 of the hoisting device is fixedly installed, the billet used for mold steel production is lowered, and the forward and reverse motor 102 is turned to drive the bidirectional lead screw 108 to rotate. The bidirectional lead screw 108 rotates and moves the two movable slides 103 towards each other. When the movable slides 103 move, the anti-slip clamps 107 at both ends are in the clamping distance. Then, the cylinder 104 moves to drive the movable connecting seat 106 to rise. When the movable connecting seat 106 rises, the bearing drives the two anti-slip clamps 107 to clamp and fix the billet to the side, so as to facilitate the hoisting and fixing of the billet by the main body 100 of the hoisting device.

[0032] Before the main body 100 of the hoisting device is used, the cylinder 104 passes through the inside of the fixing ring 1041. The fixing ring 1041 is fixedly installed on the lower surface of the main frame 105 by the fixing screw 1044. When the cylinder 104 is frequently adjusted and clamped, the telescopic end of the cylinder 104 is exposed to external dirt. When the telescopic end of the cylinder 104 is raised and lowered, the cylinder 104 inside the fixing ring 1041 contacts the scraper 1042 to scrape and clean it. After scraping, the cylinder 104 continues to move and drives the telescopic end of the cylinder 104 to contact the outer surface of the cleaning brush 1043 for cleaning again. This facilitates the scraping and cleaning operation and does not easily cause the telescopic end of the cylinder 104 to be obstructed. It allows for smooth telescopic clamping and hoisting, improving the convenience of scraping and cleaning the telescopic end of the cylinder 104 when the main body 100 of the hoisting device is used for hoisting operations of mold steel billet production.

[0033] Finally, when the main body 100 of the hoisting device is used after installation, and when the movable slide 103 moves on the outer surface of the bidirectional lead screw 108, the top two sides of the movable slide 103 and the interior of the horizontal plate 101 are smoothly moved by the guide rollers 1031. At the same time, the movable slide 103 moves the reinforcing support plate 1032 and the side support plate 1033. Simultaneously, the top of the movable slide 103 drives the slider 1035 to slide inside the slide groove 1034. This facilitates the stable support and sliding operation of the movable slide 103 during movement through the reinforcing support plate 1032 and the side support plate 1033. When the steel billet is clamped and fixed, the side support of the movable slide 103 is strengthened by the reinforcing support plate 1032 and the side support plate 1033 during lifting. Even when shaking, the hoisting is more stable and less likely to cause instability and danger. This improves the support stability of the main body 100 of the hoisting device for the movable slide 103 during the hoisting operation of the mold steel billet.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
