Cause the waste of human resources.In order to ensure the intensity of suspension hook, the weight of suspension hook is generally large, and long-time frequent operation can be quickly
Cause manpower tired and the damage of tendon.
Utility model content
The purpose of this utility model there is provided a kind of Weight type Automatic unhooking hook, both achieved suspension hook when unloading goods from
The dynamic function that comes off, has ensured that again weight does not falls off during handling, saves manpower, safe and reliable and easy and simple to handle.
The technical solution of the utility model is: a kind of Weight type Automatic unhooking hook, it is characterized in that suspension hook head is tied by rod
Structure fixes connecting shackle weight, and suspension hook is connected with spin head by stationary spindle, swivel head and suspension ring nut and opening
Pin rotates to hang and connects, and upper rocker-counterweight is fixedly connected on rocking bar head, upper rocking bar bottom wherein and suspension hook weight and connects
Being rotationally connected in the middle part of bar, connecting rod is rotationally connected on top and upper rocking bar, is rotationally connected in bottom and lower rocking bar, lower rocking bar and suspension hook
Connection is rotated over, so that suspension hook, upper rocking bar, connecting rod and lower rocking bar constitute double rocker mechanism, under lower rocking bar at suspension hook suspension ring
Portion is fixing connects lower rocker-counterweight, and lower rocking bar head is porose, and suspension hook hangs head and inserts in the hole, and seals and hangs mouth, and torsion spring is arranged on and shakes
On the bearing pin that bar and link rotatable connect.
This utility model achieves suspension hook when putting down goods, and suspension hook under gravity can Automatic-falling;At lifting cargo
Time, suspension hook mouth can by rocking bar self-closed under gravity locked, thus solve without manually breaking off relations when putting down goods,
The practical problem come off during hanging with goods.
This utility model saves manpower, safe and reliable and easy and simple to handle.Can be prevented effectively from during lifting, goods
The problem that may come off, and the function that when realizing putting down goods, suspension hook is automatically-unhooked under the effect of gravity and lever, make hanging
During goods safer, and without manually breaking off relations when unloading goods.Simple in construction, saves manpower, easy to operate.
Accompanying drawing explanation
Fig. 1 is suspension hook structure diagram during hoisting heavy.
Fig. 2 is the suspension hook structure diagram in off working state.
In figure, label is as follows: 1-suspension hook weight, the upper rocker-counterweight of 2-, 3-swivel head, 4-suspension ring, 5-steel wire rope, 6-nut,
Rocker-counterweight, 12-connecting rod, 13-torsion spring, the upper rocking bar of 14-under rocking bar, 11-under 7-split pin, 8-stationary spindle, 9-suspension hook, 10-.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
This utility model is to fix in ordinary lifting hook opening oblique direction to connect one end and be furnished with the bar of weight, at itself and suspension hook
Middle part bearing pin and spin head connect;Being provided with double rocker mechanism at suspension hook opening part, its frame is suspension hook, on lower rocking bar
Suspension hook head is just inserted in hole when hoisting heavy, and connecting rod and upper end rocking bar conllinear;And it is furnished with conjunction at the head of two rocking bars
Suitable counterweight.
As it is shown in figure 1, the size of suspension hook determines according to the maximum weight of required lifting.Suspension hook head is solid by rod shaped structure
Determining connecting shackle weight 1, suspension hook 9 is rotationally connected with swivel head 3 with stationary spindle 8.Swivel head 3 and suspension ring 4 nut 6 and opening
Pin 7 rotatably hangs connection.The firm bolt of steel wire rope 5 is in the circular rings on suspension ring 4 top.Upper rocker-counterweight 2 is fixedly connected on
Upper rocking bar 14 head.It is rotationally connected in the middle part of upper rocking bar 14 bottom wherein and suspension hook weight 1 connecting rod.Connecting rod 12 top and on
Rocking bar 14 is rotationally connected, and is rotationally connected in bottom and lower rocking bar 10.Lower rocking bar 10 and suspension hook 9 rotate over even at suspension hook suspension ring
Connect, so that suspension hook 9, upper rocking bar 14, connecting rod 12 and lower rocking bar 10 constitute double rocker mechanism.Under the fixing connection in lower rocking bar 10 bottom
Rocker-counterweight 11.Lower rocking bar 10 head is porose, and suspension hook 9 hangs head and inserts in the hole, and seals and hangs mouth.Torsion spring 13 is arranged on rocking bar 14 He
On the bearing pin that connecting rod 12 is rotationally connected.
During work, manually hanging upper weight, the clockwise torque around stationary spindle 8 rotation that its weight produces is far longer than
The anticlockwise moment that suspension hook weight 1 produces, so that suspension hook is positioned at position shown in Fig. 1.Now, produce at lower rocker-counterweight 11
Under anticlockwise moment, making lower rocking bar 10 around the bearing pin connected with suspension hook 9, go to position shown in Fig. 1, suspension hook 9 hangs under head inserts and shakes
In hole on bar 10, sealing and hang mouth, connecting rod 12 and upper rocking bar 14 are located exactly at straight line, are in dead-centre position.From regardless of
Hanging over suspension ring in suspension hook to the lower great impulsive force of rocking bar 10, lower rocking bar 10 also will not move, thus firm closing suspension hook 9
Hang mouth, prevent hoisting heavy when lifting because impact and concussion come off, cause major accident.It is arranged on rocking bar 14 and connecting rod 12
Torsion spring 13 on the bearing pin being rotationally connected, is possible to prevent when suspension hook impact or concussion, and impact force makes double rocker mechanism
By the dead-centre position shown in Fig. 1, reliable guarantee suspension hook mouth will not be opened, and prevents weight from coming off during hanging and causes tight
Weight accident.
When unloading weight, when weight touches landing platform, and steel wire rope 5 relaxes, and the clockwise moment that weight produces disappears,
The clockwise moment that the anticlockwise moment that suspension hook weight 1 produces produces slightly larger than suspension hook deadweight, suspension hook 9 will be around stationary spindle 8
Rotate counterclockwise to position shown in Fig. 2.Meanwhile, the anticlockwise moment that upper rocker-counterweight 2 produces, overcome the elastic force of torsion spring 13, make
Double rocker mechanism passes through dead-centre position, and lower rocking bar 10 acts on the up time of generation jointly at upper rocker-counterweight 2 and lower rocker-counterweight 11
Under pin moment loading, going to position shown in Fig. 2 clockwise, so that suspension hook is closed mouth and opened, weight is linked up with at himself gravity
Effect under, automatically come off smoothly from suspension hook 9, it is achieved the function of suspension hook Automatic-falling.
When mounting weight next time, hold the suspension hook weight 1 being combined with hands simultaneously and upper rocker-counterweight 2 is used clockwise
Power, the anticlockwise moment produced because of suspension hook weight 1 is slightly larger than the clockwise moment that suspension hook deadweight produces, and the least power can make to hang
It is hooked under the state that mouth is opened and rotates counterclockwise, hang up weight smoothly, when suspension hook rises painstaking, unclamp and hold suspension hook weight 1 He
The hands of upper rocker-counterweight 2, lower rocking bar 12 can be positioned at position shown in Fig. 1 under the effect of lower rocker-counterweight 11 again, thus firm
By closing suspension hook mouth, prevent from breaking off relations in hoisting process and causing strict liability accident.
