[0002] A hook is the most common type of lifting tool in a hoisting machine. The hook is often suspended on the steel wire rope of the hoisting mechanism by means of a pulley block and other components.

[0003] At present, many of the capping and uncapping of the heat preservation cover of a torpedo-type molten iron ladle are completed by an electromagnetic crane lifting the heat preservation cover. The heat preservation cover is adsorbed by energizing the electromagnet. However, when the surface temperature of the heat preservation cover on the torpedo-type molten iron ladle reaches a certain temperature (above 550 °C), the high temperature will cause the magnetism of the electromagnetic lifting to disappear, thereby affecting the capping and uncapping of the heat preservation cover. A method for covering a torpedo ladle with an electromagnetic type and a device for covering and uncovering a torpedo ladle with an electromagnetic lifting type with the application number 20241066893,08 and the patent number CN218109341U both adopt an electromagnetic method to clamp the heat preservation cover;

Specific implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-7 , the present invention provides a technical solution: a heat preservation cover clamping device for a torpedo - type hot metal ladle, including a heat preservation cover 1 and a clamping mechanism 2. A clamping cap 3 is installed on the heat preservation cover 1, and the clamping cap 3 is clamped by the clamping mechanism 2. The clamping mechanism 2 includes,

[0030] Mechanical claws 21, symmetrically arranged in two, and the clamping cap 3 is clamped by the mechanical claws 21;

[0031] Telescopic mechanism 22, arranged between the two mechanical claws 21, and the clamping or releasing of the clamping cap 3 by the mechanical claws 21 is controlled by the expansion and contraction of the telescopic mechanism 22, that is, driving the two mechanical claws 21 to move in the same or opposite directions;

[0032] Walking wheels 23, installed on the longitudinal sides of the mechanical claws 21, for the mechanical claws 21 to slide under the action of the telescopic mechanism 22. The walking wheels 23 are composite bearing walking wheels;

[0033] Mechanical claw guide rails 24, and the walking wheels 23 are installed in the mechanical claw guide rails 24 for the walking wheels 23 to move linearly;

[0034] Frame 26, and the mechanical claw guide rails 24 are installed on the symmetric side ends of the frame 26.

[0035] The telescopic mechanism 22 is an electric cylinder.

[0036] The lower end of the clamping cap 3 is a columnar tube and is coaxial with the heat preservation cover 1. Its upper end is a convex platform protruding outwards. The outer diameter of the clamping cap 3 is 300 mm, and the outer diameter of the convex platform of the clamping cap 3 is 500 mm.

[0037] The mechanical claw 21 includes a mounting plate 211, and the traveling wheels 23 are mounted on the mounting plate 211;

[0038] The clamping plate 212 is mounted on the lower end of the mounting plate 211 through an angle steel, and the portion of the clamping plate 212 that clamps the clamping cap 3 is a concave arc surface;

[0039] The connecting block 213 is mounted in the middle of the side end of the mounting plate 211, and the end and the extending end of the telescopic mechanism 22 are respectively connected to the connecting block 213.

[0040] A limit block 7 is mounted in the middle of the mechanical claw guide rail 24 for limiting the movement of the mechanical claw 21 when it is in the clamping state.

[0041] When in the state of clamping the clamping cap 3, the telescopic mechanism 22 shortens, the telescopic mechanism 22 drives the two mechanical claws 21 to approach each other, and the traveling wheels 23 move in the mechanical claw guide rail 24. At this time, one of the mechanical claws 21 will first contact the limit block 7. By limiting the stroke of this mechanical claw 21, when the telescopic mechanism 22 shortens, it drives the other mechanical claw 21 to approach the limit block 7. When both mechanical claws 21 are in contact with the side of the limit block 7, the two clamping plates 212 complete the clamping of the clamping cap 3.

[0042] A clamping mechanism limit frame 4 is mounted on the frame 26 for limiting the movement of the mechanical claw 21 when it is in the released state to prevent the traveling wheels 23 on the mechanical claw 21 from slipping out of the mechanical claw guide rail 24.

[0043] When in the state of releasing the clamping cap 3, the telescopic mechanism 22 extends, pushing the two mechanical claws 21 to move in the opposite direction, and the traveling wheels 23 move in the mechanical claw guide rail 24. When one of the mechanical claws 21 is in contact with one side of the clamping mechanism frame 4, by limiting the stroke of this mechanical claw 21, when the telescopic mechanism 22 extends, it drives the other mechanical claw 21 to move to the other side of the clamping mechanism frame 4, so as to keep the two mechanical claws 21 in a symmetrical position, complete the release of the clamping cap 3 and the position calibration of the mechanical claw 21.

[0044] A rain shield 5 is mounted on the upper end of the clamping mechanism limit frame 4 for protecting the clamping mechanism 2.

[0045] Lifting lugs 6 are mounted on both sides of the lateral side ends of the frame 26. The lifting lugs 6 are connected to the hook shackle of the lifting mechanism through hinges, so as to facilitate lifting the clamping mechanism 2 and the heat preservation cover 1 it clamps or covering it on the pouring port of the torpedo-type hot metal ladle.
