Abstract

A crane hook mainly solves the security problem of lifting objects. The utility model comprises a primary hook, an secondary hook, a balancing weight block and a self-locking mechanism consisting of a self-locking clip, a connecting rod and a self-locking touch tablet, wherein, the upper part of the primary hook is provided with a clamping hook, the lower part of the primary hook is provided with a stop plate; the upper part of the secondary hook is provided with a slideway, the upper part of the slideway is provided with a clamping groove, the secondary hook passing through the primary hook is movably connected to the middle part of the primary hook; the self-locking clip and the self-locking touch tablet are respectively fixed to the upper and the lower ends of a connecting rod, the connecting rod is arranged on a fixed frame in the middle part of the primary hook in a sliding manner; the balancing weight block is arranged in the slideway in a sliding manner and can be adjusted and fixed by a connecting bolt, the two ends of the self-locking clip can respectively hook the clamping hook arranged on the upper part of the primary hook and the clamping groove arranged on the upper part of the secondary hook, which fulfills the purpose of self locking. By adopting the self-locking structure, the utility model facilitates the automation of the hooking and unhooking, therefore, the hooking and unhooking under unfavorable conditions such as high altitude can be realized without being operated by a person and can prevent the hook from falling off. In addition, the utility model has the advantages of a simple structure, convenient use and safe use.

Description

The elevator machinery suspender

Technical field

The utility model relates to elevator machinery suspender field.

Background technology

Existing elevator machinery suspension hook, because restrictions such as structure, principles, the unhook after every handling one-stop operation must realize by manually going.Be that suspender needs the anti-steel rope trip mechanism of artificial hand push more, make the rotation of trip mechanism hour hands and open suspension hook, then steel rope is hung in the main hook, openhandedly fall trip mechanism, at this moment because of the effect of center of gravity, it can rotate counterclockwise, and closes suspension hook up to contacting with the suspension hook afterbody, steel rope can not be broken off relations voluntarily, play the lock hook effect.Take down steel rope, want the hand push trip mechanism equally, take steel rope away from main hook again.This elevator machinery suspension hook is especially in use in the dangerous object of handling as 1.3 tons of transportation molten iron torpedo hot metal mixer car blocks, the staff need emit in the tank body more than 600 ℃ high temperature to climb to the operation of hanging, break off relations on the tank body top, consider these factors, maintenance again behind the tank body natural cooling such as generally have only, will consume a large amount of energy that tank body is heated like this.

Summary of the invention

The purpose of this utility model is to provide a kind of elevator machinery suspension hook simple in structure, easy to use, safe.For achieving the above object, the utility model comprises main hook, auxiliary hook, self-locking mechanism, fixed mount, clump weight; Described main hook top is provided with a grab, and the bottom is provided with positioning plate; Fixed mount is fixed in the main hook middle part;

Described auxiliary hook top has a chute that supplies clump weight to move, and top has a draw-in groove, and auxiliary hook passes main hook, and activity is connected in the main hook middle part;

Described self-locking mechanism comprises self-locking clamp, pipe link, self-locking touch panel; Self-locking clamp, self-locking touch panel are individually fixed in the two ends up and down of pipe link, and this pipe link is slidedly arranged in the fixed mount at main hook middle part, can move up and down; Described clump weight is slidedly arranged in the chute, and can be regulated by tie bolt and fix, and grab and the auxiliary hook top draw-in groove that trip is lived main hook top can be distinguished in the two ends of self-locking clamp, reaches the self-locking purpose.

The utility model makes extension, breaks off relations for automatic owing to adopt self-locking structure, and extension, unhook under high-altitude or other rough sledding do not need the people and then to go operation, and can prevent to come off.

Description of drawings Fig. 1 is a structural representation of the present utility model.Fig. 2 is the utility model self-locking state scheme drawing.Fig. 3 is the utility model lifting view.Fig. 4 is a schematic perspective view of the present utility model.

The specific embodiment

Shown in Fig. 1,4, the utility model comprises main hook 1, auxiliary hook 2, self-locking mechanism 3, fixed mount 4, clump weight 5; Main hook 1 top is provided with a grab 101, and the bottom is provided with positioning plate 9; Fixed mount 4 is fixed in main hook 1 middle part; Auxiliary hook 2 tops have a chute 201 that supplies clump weight 5 to move, and top has a draw-in groove 202, and auxiliary hook 2 passes main hook 1, is connected in main hook 1 middle part by tie bolt 6 activities; Self-locking mechanism 3 comprises self-locking clamp 31, pipe link 32, self-locking touch panel 33; Self-locking clamp 31, self-locking touch panel 33 are individually fixed in the two ends up and down of pipe link 32, and this pipe link 32 is located in the fixed mount 4 at main hook 1 middle part; Clump weight 5 is slidedly arranged in the chute 201, and can regulate fixing by tie bolt 7.

As shown in Figure 1, 2, during the lifting object, open auxiliary hook 2, with hanging object 11 upper lift rings 10, hang on the main hook 1, close auxiliary hook 2, main hook 1 is risen to be subjected to suspended object 11 gravity, this moment auxiliary hook 2 afterbody elbows and suspended object 11 upper lift rings, 10 contacts side surfaces and locking can not opened.Subsequently clump weight 5 on the auxiliary hook 2 is moved on to auxiliary hook 2 chutes 201 outsides, make auxiliary hook 2 centers of gravity at head, automatically-unhooked.At this moment just can lift by crane main hook 1, suspended object 11 be hung on the position of be difficult for breaking off relations or in the environment, when main hook 1 slowly descended, auxiliary hook 1 elbow no longer contacted with suspension ring 10.Because auxiliary hook 1 center of gravity is at head, auxiliary hook 1 will rotate counterclockwise and open automatically, and auxiliary hook 1 middle part draw-in groove 202 is slided in the self-locking clamp 31, makes auxiliary hook 2 be the self-locking state of opening, and can't close again, and main hook 2 just can leave suspension ring 10.

Automatic hitch is as shown in Figure 3: auxiliary hook 2 was opened and during self-locking state, with the clump weight on it 5, is moved on to auxiliary hook 2 chutes 201 inboards in above-mentioned being.At this moment, auxiliary hook 2 centers of gravity are at afterbody, remove to connect the hanging object 11 that is difficult for hook with regard to available main hook 1 then, behind suspended object 11 suspension ring 10 on main hook 1 hook, slowly descend again, make self-locking touch panel 33 on the suspension ring 10 top percussion main hooks 1, make on the self-locking mechanism 3 and move, self-locking clamp 31 leaves auxiliary hook 2 supermedial draw-in grooves 202, auxiliary hook 2 loses self-locking, and be subjected to the tailheaviness effect, will clockwise rotate and close, main hook 1 continues to rise, auxiliary hook 1 elbow again with suspension ring 10 contacts side surfaces by locking, and limited plate 9 is spacing, plays the anticreep effect, just hanging object 11 can be hung appointment place subsequently.
