Technical field
The utility model relates to weight-lifting equipment technical field, relates in particular to a kind of crane hook.
Background technology
Crane is owing to can realizing weight at space parallel motion or vertical lift, the fields such as building, machinery have been applied in widely at present, it is the indispensable weight-lifting equipment of workpeople, yet the object of existing crane lifting is again very large very heavy conventionally, once therefore weight breaks off relations to fall and causes that accident tends to cause workman dead or residual, abnormally dangerous.Therefore there is in use potential safety hazard in the crane hook of prior art.
Utility model content
The technical matters existing for solving above-mentioned prior art, the utility model provides a kind of safety performance better crane hook, the gib head comprising, protection post, bolt, nut, position-limited lever, described gib head is provided with protective trough and storage tank, in described protective trough, be provided with bullet piece and spring, described bullet piece is provided with inclined-plane, described spring one end is connected the other end and is connected with protective trough bottom surface with bullet piece, described protective trough is provided with shape and the identical detent of protection post periphery, described storage tank inwall is provided with fixed end, described fixed end is provided with the through hole passing for bolt, described protection post is cylindrical member, described protection post one end is provided with movable end, described movable end is provided with the internal thread hole mating with bolt, described movable end is rotationally connected by screw bolt and nut and fixed end, described gib head is provided with storage tank, in described upper storage tank, be provided with fixed part, described position-limited lever upper end is provided with the movable part being rotationally connected by pin and fixed part, the lower end of described position-limited lever is provided with radius arm, described radius arm is connected with protection post by limited screw.
During use, first weight is hung in gib head, then rotate protection post and make entering in protective trough of its, protection post is against and on the inclined-plane of bullet piece, by inclined-plane, bullet piece is applied to downward pressure and make its decline, after loosing one's grip, bullet piece is stuck in detent protection post protection post jack-up under the effect of spring, and then rotary spacing bar makes protection post enter the three side sealing that position-limited lever and radius arm surround to close in the interval of one side open, then with limited screw by an open face closure.
Crane hook of the present utility model contrasts existing crane hook advantage and is:
1, by bullet piece and spring are set, protection post can be located automatically, stop weight to depart from gib head.
2, the identical detent of setting and protection post periphery shape, is used formation face between protection post and gib head to contact, and makes to protect intensity better, can not skid.
3, the protection post of the present utility model process that the side in gib head can not hang into gib head weight when weight is hung into gib head produces interference.
4, because protection post and the unique lap position of position-limited lever wobble area are exactly that protection post is when being connected with position-limited lever, so after protection post is connected with position-limited lever, when if spring is aging or damage cannot protection post is positioned in detent, position-limited lever still can be positioned at protection post in protective trough, makes protection post prevent that weight from departing from gib head.
5, protection post adopts cylinder design, and intensity is better.
The utility model can also be done following improvement: on gib head, be provided with rubber pad, the both sides of described rubber pad are provided with the through hole passing for rope, by rope, pass the through hole of rubber pad and rubber pad is tied up to the outside face at the position contacting with weight at gib head, because can skid when weight rocks on gib head, between gib head and weight, can produce the cliding friction of rigidity, wearing and tearing mutually, the position contacting with weight at gib head arranges rubber pad and can stop gib head and weight mutually to wear and tear, and also can stop weight to skid because rocking on gib head.

The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Crane hook, the gib head 1 comprising, protection post 2, bolt 7, nut 8, position-limited lever 12, described gib head 1 is provided with protective trough 9 and storage tank 10, in described protective trough 9, be provided with bullet piece 3 and spring 4, described bullet piece 3 is provided with inclined-plane, described spring 4 one end are connected the other end and are connected with protective trough 9 bottom surfaces with bullet piece 3, described protective trough 9 is provided with shape and the identical detent 11 of protection post 2 peripheries, described storage tank 10 inwalls are provided with fixed end 5, described fixed end 5 is provided with the through hole passing for bolt 7, described protection post 2 is cylindrical member, described protection post 2 one end are provided with movable end 6, described movable end 6 is provided with the internal thread hole mating with bolt 7, described movable end 6 is rotationally connected with fixed end 5 by bolt 7 and nut 8, described gib head 1 is provided with storage tank 19, in described upper storage tank 19, be provided with fixed part 14, described position-limited lever 12 upper ends are provided with the movable part 15 being rotationally connected by pin 16 and fixed part 14, the lower end of described position-limited lever 12 is provided with radius arm 18, described radius arm 18 is connected with protection post 2 by limited screw 17.
During use, first weight is hung in gib head 1, then rotate protection post 2 and make entering in protective trough 9 of its, protection post 2 is against and on the inclined-plane of bullet piece 3, by inclined-plane, bullet piece 3 is applied to downward pressure and make its decline, after loosing one's grip, bullet piece 3 is stuck in detent 11 protection post 2 protection post 2 jack-up under the effect of spring 4, and then rotary spacing bar 12 makes protection post 2 enter position-limited lever 12 to close in the interval of one side open with the three side sealing that radius arm surrounds, then with limited screw 17 by a face closure of opening.
Crane hook of the present utility model contrasts existing crane hook advantage and is:
