Abstract
A kind of simple special suspension clamp, including jig arm, clamping plate, screw mandrel, nut, withhold.Two jig arm upper ends are connected, and fix one and withhold, and every jig arm lower end connects one piece of clamping plate.Installed below a piece jig arm and opened up a through hole relative to nut location below a nut, another jig arm.A piece screw mandrel is screwed into nut, and pushing out ring is enclosed on the step of screw mandrel front end, and screw mandrel passes through the corresponding through hole of opposite side, and an end socket is fixed in screw mandrel termination.Screw mandrel rear end is connected with crank.During lifting, crank is pulled, two pieces of clamping plates are suitably strutted with screw mandrel, clamping plate is clipped in square objects both sides, then inverts crank, it is appropriate to clamp according to institute's hanging object weight, you can lifting, during unloading, crank is suitably rotated, goods is unclamped, that is, unloads.This suspension clamp is applied to lifting square body, and such as metal, stone, clump are not easy to the square body hung with rope coil, simple in construction, easy to operate.Suspension clamp can hang over and be used on the suspension hooks of all lifting appliances such as boat car, truck crane.
Description
Technical field
The invention belongs to suspender field, particularly a kind of simple special suspension clamp.
Background technology
The lifting of existing square metal, stone, clump for smooth surface, it is all never fast
Method.It is very bad with rope bundle because these square bodies, length size is all similar, intersect bundle square body with steel wire rope several
Individual face, ties not tight.A kind of special fixture is mounted with some vehicles, opening and closing for jig arm clamping plate is controlled with dynamic power machine
Hold together, but this device is more complicated, it is in each lifting amount less, laborious more again in the case of installing/dismounting fixture, it is very numb
It is tired.
The content of the invention
The invention aims to overcome the shortcomings of the special fixture of existing lifting square objects, there is provided a kind of easy
For pressing from both sides the special suspension clamp of specific square objects, hereinafter referred to as suspension clamp.
What the present invention was realized in：A kind of simple special suspension clamp, including jig arm, clamping plate, screw mandrel, nut, withhold.One
It is provided with jig arm in a nut, another jig arm and is provided with a through hole.A piece screw mandrel is screwed into nut, and screw mandrel front end is worn
The through hole crossed in another jig arm.Screw mandrel is fixed with crank on this one end termination of nut, and an end socket is fixed in screw mandrel front end.
Two jig arm lower ends are respectively connected with one piece of clamping plate.During lifting, crank is pulled, two pieces of clamping plates are strutted suitable distance with screw mandrel,
Clamping plate is clipped in lifted square objects both sides, then reversely pulls crank, according to institute's hanging object weight, appropriate to clamp, you can lifting,
During unloading, crank is suitably rotated, goods is unclamped, that is, unloads.Jig arm has certain elasticity.Two jig arm upper ends link together, and
One is connected with to withhold.Have in front of screw mandrel and a pushing out ring is installed in one section of head for being less than screw mandrel diameter, head.
The advantage of the invention is that：The distance between two pieces of clamping plates of special suspension clamp are less than square body two in its natural state
The distance between side, the present invention directly sets two jig arm two pieces of clamping plate upper ends, and a screw mandrel is installed between two jig arm
Nut.During lifting, two pieces of clamping plate suitable distances are strutted with screw mandrel, two pieces of clamping plates are clamped after square body, then are suitably tensed with screw mandrel
Two pieces of clamping plates.According to institute's hoisting object weight, can appropriate grip objects, make lifting more safe and reliable.It is simple in construction, operation letter
It is single.
Brief description of the drawings
Fig. 1 is the structure and suspension clamp of a kind of simple special suspension clamp just in hoisting object situation map.
In accompanying drawing：Clamping plate 1, crank 2, nut 3, jig arm 4, hook 5, steel wire rope 6, withhold 7, screw mandrel 8, pushing out ring 9, end socket
10th, square body 11.
Embodiment
It is the structure and suspension clamp of a kind of simple special suspension clamp just in hoisting object situation map in Fig. 1.Two upper ends of jig arm 4
It is connected, top fixes one and withholds 7.Two lower ends of jig arm 4 are all connected with one piece of clamping plate 1.Clamping plate 1 is plate-like, in Fig. 1
In only see its thickness direction.Clamping plate 1 is more much broader than jig arm 4.Two pieces of lower ends of clamping plate 1 are provided with inclined-plane.Two jig arm 4 are inside all
There is certain elasticity.A nut 3 is installed below the jig arm of one, the left side in Fig. 1.The lower section of jig arm 4 on the right is provided with one in Fig. 1
Individual through hole.A piece screw mandrel 8 is screwed in nut 3, and the front of screw mandrel 8 has one section of diameter to be less than the head of screw mandrel, and head and screw mandrel have a common boundary
There is a step at place.A pushing out ring 9 is packed into head.Pushing out ring is blocked on step.Head is passed through in Fig. 1 in the jig arm 4 of the right
Through hole, screw mandrel termination and end socket 10 are fixed together.Screw mandrel left end fixes a crank 2.
During lifting, switching crank 2 is rotated, and makes pushing out ring 9 that clamping plate is suitably opened a bit again, clamping plate 1 is clipped in square body 11
Both sides, then crank 2 is rotated backward, then draw two pieces of jig arm suitably to clamp square body 11 again, you can lifting square body.Shown in Fig. 1
Be steel cable 6 connect one hook 5, withhold 7 hang over hook on be ready for lifting situation.
According to the weight of square body, appropriate clamping jaws.Operative can grasp the control of switching crank and clamp journey several times
Degree.
The present invention is applied to the object that less than one ton of lifting is not bery weighed.
