Embodiment 1
[0028] as attached Figure 1-3 As shown, the present invention provides a kind of technical scheme:
[0029] An anti-falling device for lifting and transporting machinery, comprising an anti-falling mechanism 1, an I-shaped rail 2 and an electric hoist 3, the electric hoist 3 is installed on the I-shaped rail 2, the anti-falling mechanism 1 is arranged on the periphery of the electric hoist 3, and The anti-fall mechanism 1 is tightly connected with the electric hoist 3, and the top of the anti-fall mechanism 1 is connected to the top surface of the I-shaped track 2;
[0030] Anti-falling mechanism 1 comprises two groups of anti-falling brackets side by side, and anti-falling bracket comprises U-shaped plate 101, and the two side plate ends of U-shaped plate 101 are provided with convex plate 104, and the two groups of anti-falling brackets side by side The first connecting plate 105 is passed between the U-shaped plates 101, and the convex plates 104 on the two groups of anti...
Embodiment 2
[0035] Based on Embodiment 1, this embodiment has the following improvements:
[0036] as attached image 3 , 4 As shown, the adjustable limiter 103 includes a square sleeve 1031 that runs through and is fixed on the convex plate 104. A strip plate 1032 is movably inserted in the square sleeve 1031. Connection holes are distributed on the top surface of the strip plate 1032 at intervals. 1031 is connected to the strip plate 1032 by bolts, and the end of the strip plate 1032 close to the inner side of the U-shaped plate 101 is fixed with an L-shaped plate 1033 .
[0037] The bottom end of the L-shaped plate 1033 is provided with a plurality of rollers 1034 .
[0038] During installation, the strip plate 1032 is inserted in the square sleeve 1031, the position of the L-shaped plate 1033 is adjusted so that the roller 1034 is in contact with the top of the I-shaped track, and then the position of the strip plate 1032 is fixed by bolts.
Embodiment 3
[0040] Based on Embodiment 1, this embodiment has the following improvements:
[0041] as attached Figure 6 , 7 As shown, the inner bottom of the U-shaped board 101 is provided with an extension board 107 , and the extension board 107 is detachably connected to the U-shaped board 101 .
[0042] Through the above-mentioned design, the falling support range can be increased, and the protection of the device can be improved.

Abstract
The invention relates to the technical field of hoisting and transporting machinery, in particular to an anti-falling device for hoisting and transporting machinery. The anti-falling device comprises an anti-falling mechanism, an I-shaped track and an electric hoist, the electric hoist is mounted on the I-shaped track, the anti-falling mechanism is arranged on the periphery of the electric hoist, the anti-falling mechanism is in compression connection the electric hoist, and top of the anti-falling mechanism is connected with the top surface of the I-shaped rack. The anti-falling device can be additionally arranged on the mounted electric hoist, the mounting operation is very simple, the anti-falling device is connected with the I-shaped rack in a limiting and rolling mode through an adjustable limiting piece, and through a pressure sensor, when the electric hoist falls, an alarm is given in time and an operation circuit is cut off.
Description
technical field [0001] The invention relates to the technical field of hoisting and transporting machinery, in particular to a fall prevention device for hoisting and transporting machinery. Background technique [0002] The electric hoist is the lifting equipment of the crane. It is installed on the crane and the gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation, and convenient use. It is used in industrial and mining enterprises, storage and docks, etc. The structure of the electric hoist is compact. , The electric hoist whose motor axis is perpendicular to the drum axis adopts a worm gear transmission. At present, the transmission devices of the existing electric hoists for cranes are all exposed on the track, and the fixing effect is poor. When the bearing capacity of the hook is large, the electric hoist may fall, which affects people's safety. and load quality. [0003] Patent CN201921512944.1 discloses an electric...
