Detailed Description
In order to make the objects and advantages of the present invention more apparent, the following detailed description of a vertical weight drop preventing device according to the present invention is provided with reference to the accompanying drawings and embodiments.
As shown in fig. 2 and fig. 3, the vertical heavy hammer anti-falling device comprises two oppositely arranged support structures 1, a fixed frame 2 is connected to the support structures 1, two oppositely arranged connecting shafts 3 are mounted on the fixed frame 2, and two ends of each connecting shaft 3 are connected with a hook body 5 through torsion springs 4; adjacent hooks 5 on different connecting shafts 3 are connected through a first connecting line 6; the two first connecting lines 6 are connected through two second connecting lines 7; the second connecting line 7 passes through the ring piece 9; third connecting lines 10 respectively penetrate through two ends of the ring piece 9; one end of each of the two third connecting lines 10 is connected with a speed difference anti-falling device 11, and the other end is connected with the end part of a heavy hammer roller 12; the end part of the connecting end of the third connecting line 10 and the speed difference anti-falling device 11 is connected with the end part of the heavy hammer roller 12 through a fourth connecting line 13; the speed difference anti-falling device 11 is fixedly connected with a fixed seat 8.
The supporting structure 1 is a wall or a frame body. The speed difference anti-falling device 11 is a ratchet type speed difference anti-falling device, and is particularly shown in patent 201820828604.9; or an electromagnetic rheological damper, as shown in particular in patent 201820828604.9. The first connecting line 6, the second connecting line 7, the third connecting line 10 and the fourth connecting line 13 are all steel wire ropes.
The fixed seat 8 is fixedly connected with the fixed frame 2.
When the belt conveyor normally works, the torsion spring provides certain tension to enable the steel wire rope to be kept in a horizontal state firstly, the speed difference anti-falling device is connected with the heavy hammer (namely the heavy hammer roller), and the normal up-down running speed generated by the heavy hammer is extremely low under the normal work, so that the in-and-out of the steel wire rope in the speed difference anti-falling device cannot be influenced. When the rubber belt is broken, the heavy hammer suddenly and violently drops, the speed is high, the ratchet wheel in the speed difference anti-falling device is locked, the steel wire rope cannot stretch, the steel wire rope connected with the torsion spring starts to bear the load, the torsion spring is compressed, the horizontal steel wire rope is changed into an angle, however, the angle is small, the whole system is mainly only subjected to two horizontal forces which are mutually offset, the heavy hammer is changed into six-point load from two-point load, the vertical acting force on a floor slab in contact with the heavy hammer is small, and therefore the safety is guaranteed. Meanwhile, the first connecting line 6, the second connecting line 7, the third connecting line 10 and the fourth connecting line 13 form a three-dimensional net structure, so that the bearing points are increased, and meanwhile, the swinging of a heavy hammer is effectively prevented
The above is merely an example of the present invention and is not intended to limit the scope of the present invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
