Embodiment 1
[0027] Such as figure 1 As shown, this embodiment provides a protective device for crane hooks, including crane beam 1, hook slider 21, pulley 22, double hook 13, slider A 24, slider B 18 and arc protection Set 7, a hook slider 21 is set on the crane beam 1, a pulley 22 is arranged under the hook slider 21, a double hook 13 is arranged under the pulley 22, and sliders are symmetrically arranged at both ends of the hook slider 21 A 24 and slider B 18, the bottom of slider A 24 and slider B 18 are riveted and fixed with an arc-shaped protective cover 7, and the bottom of the slider A 24 is also provided with a telescopic link A 3, and the telescopic link A 3 A telescopic link a 5 is hingedly connected, the end of the telescopic link a 5 is provided with a hemispherical protective cover A 6, and the bottom of the slider B 18 is also provided with a telescopic link B 17, and the telescopic link B 17 is hingedly connected with a telescopic link b 11, the end of the telescopic link...
Embodiment 2
[0030] Such as figure 1 As shown, the present embodiment is further optimized on the basis of embodiment 1, and the specific implementation scheme is as follows:
[0031] A spring group 2 is arranged between the outer wall of the telescopic connecting rod A 3 and the telescopic connecting rod B 17 and the inner wall of the arc-shaped protective sleeve 7 .
[0032] In this embodiment, when the telescopic link A and the telescopic link B are controlled to rise and fall, vibration will be generated. A spring group is arranged between the outer wall of the rod B and the inner wall of the arc-shaped protective sleeve, and the contraction elastic protection of the spring is used to play the role of shock absorption.
Embodiment 3
[0034] Such as figure 1 As shown, the present embodiment is further optimized on the basis of embodiment 1, and the specific implementation scheme is as follows:
[0035] Both the inner wall of the hemispherical protective cover A 6 and the hemispherical protective cover B 16 are provided with a fixed rod 4 , and a magnetic block 12 is provided at the end of the fixed rod 4 .
[0036] Both ends of the double hooks 13 are provided with magnetic spacers 14 that cooperate with the magnetic blocks 12 .
[0037] In this embodiment, when the double hooks of the crane enter the inner cavity of the hemispherical protective sheath A and the top openings of the hemispherical protective sheath B, the magnetic pads at both ends of the double hooks are connected with the magnetic blocks at the end of the fixed rod respectively. Attract each other, firmly fix the double hooks in the inner cavity of the hemispherical protective cover, and prevent the double hooks from rotating in the inner ...
