Cylinder barrel, the piston rod of the hydraulic jack, the hydraulic hand-pump provide power for the hydraulic jack.
Further, the hook includes gib head and the connecting shaft perpendicular to the gib head, and the connecting shaft is used to insert
In the earrings of the cylinder barrel or the piston rod.
Further, the hook also includes stop part, and the connecting shaft for preventing from being plugged in the earrings comes off.
Further, coordinate in the connecting shaft formed with plug-in opening, the stop part with plug-in opening inserting.
Further, in the connecting shaft formed with external screw thread, the stop part with the external screw thread screw thread formed with matching somebody with somebody
The internal thread of conjunction.
Compared with prior art, the advantages of the utility model and beneficial effect is：
The utility model is specifically designed chain to solve in existing large scale equipment caused hidden danger in chain Renewal process
The instrument of bar connection, in order to quickly and safely pull two free ends of chain.When in use, pars contractilis is stretched out and fixed
Hooked to suitable distance, and using two on two sections of chains to be connected in portion（Such as two freedom of crane chain
End）, drive one section of chain to be moved towards another section of chain while withdrawing pars contractilis followed by constriction device, until two sections of chains
After bar is near enough, operating personnel can be to be connected two sections of chains by chain connector.The knot of specific retractor device
Structure is not unique, refers to existing electrical retractor, hydraulic telescopic device or Pneumatic extension device to realize.
After the detailed description of the utility model embodiment is read in conjunction with the figure, other features and advantage of the present utility model
It will become clearer.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment large scale equipment chain connection instrument；
Fig. 2 is the structural representation linked up with Fig. 1；
Fig. 3 is the structural representation of hydraulic jack in Fig. 1.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described.
As shown in figure 1, the present embodiment proposes a kind of large scale equipment chain connection instrument, for make it that gross weight is larger
Both ends chain is quickly and safely close, in order to connection of the operating personnel to two sections of chains, the instrument include retractor device,
Two hooks 20（As shown in Figure 2）, wherein, retractor device includes fixed part, pars contractilis, and fixed part, pars contractilis are according to flexible
The difference of apparatus structure has different structure, and two hooks 20 are connected to the fixed part, pars contractilis, for hooking the company for the treatment of
On the two sections of chains connect.
Between two sections of chains distance it is longer without moving can not between when being connected with chain connector, specifically, with more
Change on crane exemplified by chain, can be with using this reality when needing two free ends by chain to connect to form annular
The instrument of example proposition is applied, the pars contractilis of retractor device is extend out to suitable distance so that two hooks 20 hook chain respectively
Two free ends and then pars contractilis will be withdrawn, while will drive the free end for the chain being connected with pars contractilis it is quick,
Safely close to another free end of chain, after two free ends are near enough, operating personnel can be to be connected by chain
Fitting circularizes chain connection.
In view of the length of retractor device itself, operating personnel using hook 20 hook two sections of chains when, can hook away from
From the remote position of some in the end of chain so that after pars contractilis is withdrawn, the end of two sections of chains can be driven just to abut against.
Specifically, the structure of the retractor device in the utility model is not unique, some existing retractor devices are referred to
Or lowering or hoisting gear is realized.In order to preferably ensure the safety of operating personnel, this reality while adapting to different place uses
Applying a retractor device includes hydraulic jack 10, hydraulic hand-pump（Accompanying drawing is not shown）, wherein, fixed part, pars contractilis are respectively liquid
Cylinder barrel 11, the piston rod 12 of compressing cylinder 10, as shown in figure 3, and hydraulic hand-pump is the offer power of hydraulic jack 10.Hand-hydraulic
Have a case that in pump certain length sebific duct can personnel easy to operation not close to chain to realizing progressively leaning on for two sections of chains
Closely, be advantageous to ensure the safety of operating personnel.
For the ease of the storage and carrying of instrument, two hooks 20 of the present embodiment are removably connected to cylinder barrel 11, piston
Bar 12, specifically, the cylinder barrel 11 of hydraulic jack 10, piston rod 12 are mounted on earrings.Hook 20 is including gib head 21 and vertically
In the connecting shaft 22 of gib head 21, due to needing certain structural strength, gib head 21 and connecting shaft 22 can be welded to connect.Connecting shaft 22
Inserting is adapted to earrings, in order to which two hooks 20 can be inserted into the ear of cylinder barrel 11, piston rod 12 respectively by connecting shaft 22
In ring.
In addition, in order to avoid connecting shaft 22 comes off out of earrings, hook 20 further preferably includes stop part（Accompanying drawing is not shown）,
Connecting shaft 22 for preventing from being plugged in earrings comes off.Specifically, hole position can be inserted in connecting shaft 22 formed with plug-in opening
In the side away from gib head 21 in connecting shaft 22, when connecting shaft 22 is plugged in earrings, stop part coordinates with plug-in opening inserting,
To stop the disengaging of connecting shaft 22, or, can also process external threads in connecting shaft 22, stop part formed with external screw thread
The internal thread that screw thread coordinates, for example, large-scale nut, when connecting shaft 22 is plugged in earrings, stop part is threadedly connected to connection
Axle 22, to stop the disengaging of connecting shaft 22.
In another embodiment of the present utility model, it can also further simplify retractor device, specifically, retractor device bag
Include framework and be threadedly connected to the connecting rod of framework, fixed part, pars contractilis are respectively framework, connecting rod, due between framework, connecting rod
Threaded connection, can be to realize the flexible of connecting rod during pivot link.Certainly, during in order to avoid link rotatable
The rotation of hook 20 is driven, causes the rotation for causing chain, may be such that between connecting rod and the hook being connected on connecting rod 20 in same
Axle is rotatablely connected.
More than, only it is preferred embodiment of the present utility model, is not the limit for making other forms to the utility model
System, any person skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But it is every without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model pair
Any simple modification, equivalent variations and the remodeling that above example is made, still fall within the protection model of technical solutions of the utility model
Enclose.
