Abstract
The utility model relates to an anti-falling hook, which is characterized in that: the upper portion of the hook body is provided with a hook bracket; the hook bracket, via a pin shaft, fixes hooks upon the hook body; a guiding nut is connected with an upper bracket hole in the middle section of the hook body; a connecting plate and a rib plate are fixed upon the upper bracket at the middle section of the hook body and the lower hook at the lower section via the welding method; the upper portion of a screw is connected with the hook via the pin shaft; the lower portion of the screw fixes the driving wheel upon the guiding nut via a ring and a screw nut; a crank shaft is connected via a crank sleeve hole; the crank shaft pin is fixed upon the crank shaft; the crank sleeve and the crank hinge are fixed via the welding method; and the crank hinge is connected with the hinge hole of the connecting plate via the pin shaft. The opening of the hook included angle is adjustable, thereby preventing the hook moving at the cable and the axis included angle of the bi-transmission gear is adjustable, thereby being suitable for being locked at different positions. The anti-falling hook features simple structure and convenient operation.
Description
[technical field]
The utility model relates to the power maintenance technology field, specifically, is a kind of fall arrest hook.
[background technology]
Along with the continuous development of power industry, electrical network, power transmission and transformation station get more and more, and line maintenance workload in high-altitude increases, and former hook does not have anti-degeneration function, and hook moves on cable easily, has a strong impact on work high above the ground safety.For addressing the above problem, the utility model provides a kind of energy suitable various cables from φ 13mm to φ 40mm.Easy to operate, locking can be rotated in 60 degree scopes with the crank shaft position, and the cable of locking all size is guaranteed work high above the ground safety.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of fall arrest hook is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fall arrest hook, be provided with hook support 3 on the top of hanger bulk, hook support 3 will be linked up with 2 by bearing pin 1 and be fixed on the hanger bulk, guiding nut 4 links to each other with upper bracket 5 holes at hanger bulk middle part, joint cover 10 and gusset 11 adopts on the lower draw-bar 12 of upper bracket 5 that electric soldering methods are fixed on the hanger bulk middle part and bottom, screw rod 6 tops 2 link by bearing pin and hook, screw rod 6 bottoms by enclose 8, nut 9 is fixed on drive 7 on the guiding nut 4; Crank axle 14 links by crank handle sleeve barrel 15 holes, and crank pivot pin 13 is fixed on the crank axle 14; Crank handle sleeve barrel 15 adopts electric soldering method to fix with crank hinge 19, and crank hinge 19 links by the pan of bearing pin 20 with joint cover 10; Be provided with corner guide rail 16 and corner location-plate 18 between upper bracket 5 and the crank handle sleeve barrel 15, corner guide rail 16 is provided with a corner locator 17, the ball of corner locator 17 inside withstands location hole on the corner location-plate 18 by spring, the corner location-plate is fixed, the angle of the crank axle 14 of locking.
Compared with prior art, good effect of the present utility model is:
(1) the hook angle opening of fall arrest hook of the present utility model is adjustable, can prevent that hook from moving at cable;
(2) axis angle of two travelling gears of the present utility model is adjustable, can be adapted at not maintenance and put locking;
(3) of the present utility model simple in structure, easy to operate.
[description of drawings]
Fig. 1 structural representation of the present utility model;
Fig. 2 A-A view of the present utility model.
[embodiment]
The embodiment of a kind of fall arrest hook of the utility model below is provided.
See also accompanying drawing 1, a kind of fall arrest hook, be provided with hook support 3 on the top of hanger bulk, hook support 3 will be linked up with 2 by bearing pin 1 and be fixed on the hanger bulk, guiding nut 4 links to each other with upper bracket 5 holes at hanger bulk middle part, joint cover 10 and gusset 11 adopts on the lower draw-bar 12 of upper bracket 5 that electric soldering methods are fixed on the hanger bulk middle part and bottom, and screw rod 6 tops link by bearing pin and hook 2, screw rod 6 bottoms by enclose 8, nut 9 is fixed on drive 7 on the guiding nut 4; Crank axle 14 links by crank handle sleeve barrel 15 holes, and crank pivot pin 13 is fixed on the crank axle 14; Crank handle sleeve barrel 15 adopts electric soldering method to fix with crank hinge 19, and crank hinge 19 links by the pan of bearing pin 20 with joint cover 10; Be provided with corner guide rail 16 and corner location-plate 18 between upper bracket 5 and the crank handle sleeve barrel 15, corner guide rail 16 is provided with a corner locator 17, the ball of corner locator 17 inside withstands location hole on the corner location-plate 18 by spring, the corner location-plate is fixed, the angle of the crank axle 14 of locking.
When the utility model is worked: rotate crank axle 14, rotate by two travelling gears 7 and drive guiding nuts 4 rotations, make screw rod 6 down, the opening angle of linking up with 2 is transferred to maximum.The hook 2 of anti-degeneration hook is hung on the cable.The diverse location required according to operating personnel, adjust the angle of crank axle, one corner guide rail 16 and corner location-plate 18 are arranged between upper bracket and the crank handle sleeve barrel, one corner locator 17 is arranged on the corner guide rail 16, ball in the corner locator withstands location hole on the corner location-plate by spring, the corner location-plate is fixed, the crank shaft angle degree of locking; Hinge pivot pin 20 links to each other with crank axle 14 by crank hinge 19.Rotate crank axle 14 and make screw rod 6 up, the angle of hook 2 diminishes, the clamping cables line, and hook can not move at cable, guarantees work high above the ground safety.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; can also make some improvements and modifications, these improvements and modifications also should be considered as in the protection range of the present utility model.
