[0022] See also Figure 2-4 The utility model discloses a new type of bridge crane suspension beam hook device, including a hook body, which is fixed on the crane suspension beam 2. The hook body includes a horizontal beam 3, a vertical beam 4 and a hook 1. There are two hooks 1 and two vertical beams 4, and the two hooks 1 are respectively fixed at the bottom ends of the two vertical beams 4. The horizontal beam 3 is erected between the two vertical beams 4 to form a bull horn-shaped hook, and the bottom of the horizontal beam 3 is attached to the top of the crane suspension beam 2, and the inner sides of the two vertical beams 4 are attached to the two side surfaces of the crane suspension beam 2, that is, the distance between the two vertical beams 4 is adapted to the width of the crane suspension beam 2, and the bottom of the hook 1 is attached to the top of the lower cover plate 5 of the crane suspension beam 2, that is, the height of the two vertical beams 4 is adapted to the height of the crane suspension beam 2. The horizontal beam 3, the vertical beam 4 and the hook 1 are an integrated structure, and a piece of 40mm thick Q355B steel plate is cut to form the hook body, and the structural strength is better.

[0023] The crane suspension beam hook device of the utility model adopts an ox-horn-shaped hook, and by limiting its size, when it is installed on the crane electromagnet suspension beam 2, the bottom of the hook 1 is just located at the position of the lower cover plate 5 of the electromagnet suspension beam. The lower cover plate 5 supports the ox-horn-shaped hook, and the top and bottom of the electromagnet suspension beam 2 are used to bear the weight at the same time, so as to avoid the weight of the hanging object and the electromagnet being concentrated on the web of the suspension beam during operation, which can effectively extend the service life of the hook device and reduce safety hazards.

[0024] Preferably, a receiving groove 6 for receiving the electromagnet chain is provided at the top of the hook 1 outside the vertical beam 4. When in use, the electromagnet chain is suspended in the receiving groove 6. The bottom surface of the receiving groove 6 is an arc surface 7, which can effectively prevent the electromagnet chain from moving laterally and improve the lifting stability. Furthermore, an inclined surface 8 is provided on the side of the receiving groove 6 close to the outside, and the junction of the inclined surface 8 and the arc surface 7 is located above the center of the circle corresponding to the arc surface 7, so that a step is formed at the junction of the inclined surface 8 and the arc surface 7 to prevent the electromagnet chain from sliding out of the arc surface 7 when in use.

[0025] Preferably, the hook body is inserted into the crane suspension beam 2, and the two sides of the hook body are fixedly connected to the crane suspension beam 2 through the triangular plate 9. Specifically, when installing the hook device, the hook body is inserted into the crane suspension beam 2, and then the two right-angled sides of the triangular plate 9 are used to respectively support the vertical beam of the hook body and the web of the crane suspension beam 2, and finally the triangular plate 9 is fixed by welding, so that the hook body is fixed to the crane suspension beam 2.

[0026] Preferably, a limiting structure is provided on the vertical beam 4 above the hook 1.

The screw 11 and the limiting plate 12 cover the receiving groove 6, so that the electromagnet chain will not easily escape from the receiving groove, which plays a role in blocking the electromagnet chain. When the electromagnet chain needs to be removed, the limiting plate 12 is rotated to remove the electromagnet chain from the gap between the screw 11 and the top of the hook 1. When in use, the limiting plate 12 covers the receiving groove 6 under the action of its own gravity, which is very convenient to use.

The screw rod 11 is inserted into the through hole, and the limit plate 12 is connected to the screw rod 11 by a magnet. When the limit plate 12 rotates upward, it plays a positioning role to prevent the limit plate 12 from falling off, making it convenient to remove the electromagnet chain; when the limit plate 12 is reset, it can also play a role in positioning it to prevent the limit plate 12 from rotating automatically as the crane suspension beam 2 moves.
