Description
Technical field
The present invention relates to the technical field of mechanical equipment of steel pipe deep processing, relate to a kind of coupling pre-screwing device, be specifically related to a kind of semi-automatic coupling pre-screwing device for oil casing collar.
Background technology
Coupling pre-screwing machine is the device fast box cupling being screwed into tubing and casing, carries out screw-on machine again and tighten after this process completes, and demarcates moment.Full-automatic pre-machine cost of twisting is high, and a lot of manufacturer would rather adopt artificial twisting to connect, and does not also go to buy expensive equipment, so most of manufacturer uses the mode of manually tightening.But artificial pre-twisting also has drawback, a little bit smaller box cupling can just can complete in people's operation, and box cupling people that is large for caliber, wall thickness has been difficult to, and needs more people's deallocation to close, causes the waste of personnel, and people is many simultaneously, and match ratio is more difficult.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple and reliable semi-automatic coupling pre-screwing device for oil casing collar for shortcoming of the prior art, it can overcome manually-operated defect, meet the requirement in production process, shorten the working time simultaneously, improve output.
Following technical scheme is adopted for solving technical problem of the present invention:
A kind of semi-automatic coupling pre-screwing device, comprise base, described base is arranged a lift, the other end of described lift connects hoisting rack, described hoisting rack connects floating shelf by spring, described floating shelf connects the arm of force, and the described arm of force is connected with the two ends of cylinder, and the upper end of the described arm of force arranges clamping plate.
Described floating shelf is made up of arm of force connecting plate, supporting plate, handrail, base plate and spring joint pin, described base plate vertically arranges two handrails, described supporting plate is inclined on base plate by handrail, described two blocks of supporting plates form " V " type, described arm of force connecting plate is arranged on base plate both sides, the below of described base plate arranges spring joint pin, and described spring joint pin is sleeved in spring.
Described arm of force pin shaft joint is arranged on floating shelf.
Arrange roller below described base, described roller is arranged on guide rail, and described guide rail is arranged on the ground.
The present invention adopts the clamping plate of cylinder action on the arm of force to make box cupling be fixed on floating shelf, and floating shelf connects the structure being connected hoisting rack with lift by spring simultaneously.The lift of this structure can promote the box cupling that hoisting rack moves up and down to adapt to different tube diameters, and spring connects can make floating shelf seesaw up and down, twists smoothly connect to facilitate the center of centering box cupling and tubing and casing.On base, roller is housed simultaneously, whole equipment can be made can to move on guide rail, be used for estimating and aim at steel pipe.The present invention is a kind of simple and reliable semi-automatic coupling pre-screwing device for oil casing collar, structure is simple, cost of manufacture is low, practical, goes slick, simple to operate, which overcome manually-operated defect, meet the requirement in production process, shorten the working time simultaneously, save the production cycle, improve output and production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation:
As shown in Figure 1, Figure 2, Fig. 3, shown in, a kind of semi-automatic coupling pre-screwing device, is made up of clamping plate 1, floating shelf 2, the arm of force 3, cylinder 4, spring 5, hoisting rack 6, lift 7, base 8 and guide rail 9.Base 8 is fixedly welded to connect a lift 7, the other end of lift 7 connects hoisting rack 6, in the guiding steel pipe on guide post inserted base 8 top of hoisting rack 6 bottom welding.Lift 7 can promote the box cupling that hoisting rack 6 moves up and down to adapt to different tube diameters.Hoisting rack 6 connects floating shelf 2 by spring 5.Spring 5 can make floating shelf 2 seesaw up and down, twists smoothly connect to facilitate the center of centering box cupling and tubing and casing.As shown in Figure 4, floating shelf 2 is made up of arm of force connecting plate 2a, supporting plate 2b, handrail 2c, base plate 2d and spring joint pin 2e.On base plate 2d, vertical welding two handrail 2c, supporting plate 2b are by handrail 2c oblique weld on base plate 2d, and two pieces of supporting plate 2b form " V " type, facilitate the placement of oil casing collar.The below welding spring joint pin 2e of base plate 2d, spring joint pin 2e is sleeved in spring 5.Arm of force connecting plate 2a is welded on the both sides of base plate 2d, and arm of force connecting plate 2a pinned connection two arm of forces 3, two arm of forces 3 are connected with the two ends of cylinder 4, the upper end strap 1 of the arm of force 3.Roller 10 is housed below base 8, and roller 10 is arranged on and fixes on the ground on guide rail 9, and whole equipment can move on the rail 9, is used for estimating aiming at steel pipe.
When the present invention works, promote hoisting rack 6 with lift 7 and move up and down box cupling is well contacted with floating shelf 2.Act on two arm of forces 3 by cylinder 4 again, make the clamping plate 1 being fixed on the arm of force 3 upper end produce masterpiece for box cupling, thus force box cupling to be fixed on floating shelf 2.By track 9, by whole device, toward waiting to twist, to connect steel pipe close simultaneously, and aim at screw thread, steel pipe rotary, box cupling starts pre-twisting.
In the present embodiment, the two ends of cylinder 4 are directly connected with the arm of force 3 as shown in Figure 1, are in suspension status, are reached the object of clamping by cylinder 4 effect.Cylinder 4 also can be fixed, and the two ends of cylinder 4 connect connecting rod, be connected, reach the effect of synchronous clamping by connecting rod with the arm of force 3.
