Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.
The embodiment relates to a crane derrick mast safety protection device, as shown in fig. 1 and 2, comprising: a protective frame 1 and an elastic protection member 2.
Specifically, the protective frame 1 is detachably assembled on the side of a derrick mast 3 of the crane, which is close to a lifting hook 4. The elastic protection parts 2 are arranged in a plurality of numbers, and the elastic protection parts 2 are uniformly arranged on the protection frame 1 at one side far away from the derrick 3 and used for preventing the lifting hook 4 from directly colliding with the derrick 3.
It should be noted that the elastic protection part 2 is arranged on the protection frame 1, the protection frame 1 is arranged on one side of the derrick mast 3 close to the lifting hook 4, and the protection frame 1 is arranged on the derrick mast 3 and is far away from one section of the platform of the crane. The elastic protection part 2 is fixedly assembled on the protection frame 1, so that the crane is prevented from operating, the lifting hook 4 is lifted to a certain height (usually, the free length of a lifting rope of the lifting hook 4 is about 3-8 m), and when the lifting hook 4 swings all around under the action of vibration or wind force, the elastic protection part 2 is arranged to prevent the lifting hook 4 from directly impacting the derrick mast 3 due to swinging, so that the derrick mast 3 is prevented from being deformed and damaged. In this embodiment, the length of the protection frame 1 is smaller than the length of the derrick 3.
Preferably, the protection frame 1 comprises: mounting rods 11 and crossbars 12. The installation poles 11 are arranged in two numbers, the two installation poles 11 are symmetrically arranged, the installation poles 11 are detachably assembled on the derrick mast 3, and the elastic protection piece 2 is fixedly connected with the installation poles 11. The cross rods 12 are provided with a plurality of cross rods 12, the cross rods 12 are uniformly arranged between the mounting rods 11, and two ends of each cross rod 12 are fixedly connected with the two mounting rods 11 respectively. The mounting rod 11 and the cross rod 12 are made of aluminum alloy material or wood, in this embodiment, the mounting rod 11 and the cross rod 12 are made of aluminum alloy, and the mounting rod 11 and the cross rod 12 can be fixed together by screws or welding. The weight of the protection frame 1 is reduced while the rigidity of the protection frame 1 is ensured, so that the load of the derrick 3 is reduced.
Preferably, the elastic guard 2 is a tire 21. The opening of the tire 21 is provided with a binding band closing layer. The protective frame 1 is bound on the derrick 3 through a binding band, and the tire 21 is bound on the mounting rod 11 of the protective frame 1 through the binding band.
