Abstract
The invention relates to a safety lifting hook and a manufacturing method thereof. A lifting hook is additionally provided with a supporting plate (2); the left end of the supporting plate (2) is connected with a baffle (3) through a pin (4) and a cotter pin (5); a stop pin (6) is arranged on the front lower part of the lifting hook (1); and a move pin (7) is arranged at the lower end of the baffle (3). The manufacturing method of the safety lifting hook comprises the following steps of: a. arranging the supporting plate (2) on one side of the lifting hook (1); b. connecting the supporting plate (2) with the baffle (3) through the pin and the cotter pin (5); c. arranging the stop pin (6) on the front lower part of the lifting hook (1); and d. welding the move pin (7) on the lower end of the baffle. In the invention, an anti-drop safety device is additionally arranged on a standard lifting hook, thus, unhooking does not occur when the lifting hook is crashed with other objects during lifting or lifted objects are chocked by foreign matters when falling to the ground or when a lifted container is turned over, thereby personal safety is guaranteed.
Description
Technical field
The invention belongs to the suspension hook on the weight-lifting equipment, be specifically related to a kind of safety hook and manufacture method thereof.
Background technology
Suspension hook on all weight-lifting equipments is all made by production-release design at present, does not generally all have the anti-run safety device.In case bump against with other object in the handling process or hanging object is lived by the foreign matter pad when landing, just might cause aerial unhook, or be hung the container overturning unhook casting ladle etc. of molten metal (as be equipped with), thereby suspended object may be broken, the people is injured by a crashing object; Or, the people is burnt bold and vigorous ground such as molten metals.Thereby cause unthinkable accident and tremendous loss.
Summary of the invention
Technical matters to be solved by this invention provides a kind of safety hook and manufacture method thereof, is to install the lock hook device additional on the common standard suspension hook, thereby guarantees suspension hook safety.
Technical scheme of the present invention: a kind of safety hook, it comprises suspension hook 1, sets up support plate 2 on suspension hook 1, is connected baffle plate 3 by pin 4 with spring cotter 5 at the left end of support plate 2, and backing pin 6 is arranged on the front lower place of suspension hook 1, and finger 7 is arranged on the lower end of baffle plate 3.
The manufacture method of above-mentioned safety hook, its concrete steps are as follows:
A, support plate 2 is set in a side of suspension hook 1;
B, on support plate 2, be connected baffle plate 3 with spring cotter 5 by pin 4;
C, backing pin 6 are arranged on the front lower place of suspension hook 1;
D, finger 7 are welded on the lower end of baffle plate 3.
The present invention compared with prior art has following beneficial effect: set up the anti-run safety device on the standard suspension hook, in the handling process, bump against like this or hanging object is lived by the foreign matter pad when landing with other object, can not break off relations yet, or can not broken off relations by being hung the container overturning yet, guarantee personal safety.
