Abstract
The utility model discloses a connecting hooks on pulling dolly, including the couple body, the couple body comprises gib head, stalk portion, and the gib head comprises first arc surface and second arc surface, the inslot of gib head embedding on the chain, and the stalk portion is equipped with cylindrical through hole to through the boss swing joint on round pin and the pulling dolly, the stalk portion upper end is equipped with the connecting rod, and stalk portion and connecting rod have compensatied the not enough of prior art, reasonable in design, convenient operation, safe and reliable through electrically welding fixed connection.
Description
Technical field
This utility model is related to hooking device, especially a kind of coupling hook pulling on dolly.
Background technology
At present, well known hook is seen everywhere in life, and material is generally plastics, this working of plastics hook one
Individual shortcoming is that tensile strength is low, easily breaks, this coupling hook that this utility model is related to, and material is metal, during use
Tensile strength is big, solves some potential safety hazards occurring in prior art.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of coupling hook pulling on dolly.
For solving above-mentioned existing technical problem, this utility model adopts following scheme：A kind of connection on pulling dolly
Hook, including hanger bulk, described hanger bulk is made up of gib head, shank, and gib head is by the first arc surface and the second arc surface group
Become, gib head is embedded in the groove on chain, shank is provided with cylindrical hole, and by pin with the boss activity pulling on dolly even
Connect, shank upper end is provided with connecting rod, shank is fixedly connected by electric welding with connecting rod.
Preferably, described gib head and shank are structure as a whole.
Preferably, the first described arc surface and the second arc surface are smoothly connected.
Preferably, the first described arc surface degree of crook is big, increased cooperation compactness.
Preferably, the second described arc surface is used for increasing contact area when the first arc surface is coordinated with roller.
Beneficial effect：The hook on this pulling dolly that this utility model is related to, by the multi-section circular arc face on gib head
Catch on the roller on chain, tensile strength is big, and will not worn chain roller.
This utility model employs technique scheme and provides a kind of hook pulling on dolly, compensate for prior art
Deficiency, reasonable in design, easy to operate.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Specific embodiment
As shown in Figure 1, 2, a kind of coupling hook pulling on dolly, including hanger bulk 1, described hanger bulk 1 is by hook
2, shank 3 forms, and gib head 2 is made up of with the second arc surface 5 the first arc surface 4, and gib head 2 is embedded in the groove on chain, handle
Portion 3 is provided with cylindrical hole 6, and is flexibly connected with pulling the boss 8 on dolly by pin 7, and shank 3 upper end is provided with connecting rod 9,
Shank 3 is fixedly connected by electric welding with connecting rod 9, and described gib head 2 is structure as a whole with shank 3, described the first arc surface 4
It is smoothly connected with the second arc surface 5, described the first arc surface 4 degree of crook is big, increased cooperation compactness, described second
Arc surface 5 is used for increasing the first arc surface 4 and contact area during roller cooperation.
During real work, piston rod is stretched out by the cylinder in barb adjusting means, and piston rod is flexibly connected with connecting rod 9,
Connecting rod 9 be fixedly connected on hook shank 3 on, hook shank 3 be flexibly connected with boss 8 by pin 7, now, hanger bulk 1 around
Pin 7 to be rotated down, gib head 2 snaps in the groove of chain, because gib head 2 is provided with the first arc surface 4 and the second arc surface 5,
First arc surface 4 is coordinated with the roller of chain, and the second arc surface 5 plays and increases the first arc surface 4 and contact area during roller cooperation,
Increased tensile strength, the first arc surface 4 and being smoothly connected of the second arc surface 5 are played the effect protecting roller surfaces, prevented
Roller damages at work, and so, chain just can drive pulling dolly to move at the same speed in motion, when the piston rod contracting on cylinder
Enter, hanger bulk 1 is lifted up, gib head 2 departs from chain, this coupling hook is metal material, hanger bulk 1 thickness is larger, work
When making, tensile strength is big, and does not allow frangibility.
Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute
Belong to those skilled in the art described specific embodiment can be made with various modifications or supplement or using similar
Mode substitute, but without departing from of the present utility model spirit or surmount scope defined in appended claims.
