The semi-automatic coupling pre-screwing device is simple in structure, low in manufacturing cost, strong in practicability, flexible in operation and easy to operate, shortens production cycles, and improves production efficiency.

Description

A kind of semi-automatic box cupling is screwed in advance to be put
Technical field
The present invention relates to the plant equipment field of steel pipe deep processing, relate to a kind of box cupling and be screwed in advance and put, be specifically related to a kind of semi-automatic box cupling that is used for the tubing and casing box cupling and be screwed in advance and put.
Background technology
It is the device that fast box cupling is screwed into tubing and casing that box cupling is twisted machine in advance, carries out screw-on machine after this process is finished again and tightens, and demarcates moment.The full-automatic pre-machine cost height of twisting, a lot of manufacturers would rather adopt artificial twisting to connect, and also do not go to buy expensive equipment, so most of manufacturer uses the mode of manually tightening.But artificial pre-twisting also has drawback, and a little bit smaller box cupling can just can be finished in people's operation, and people of box cupling big for caliber, wall thickness is difficult to finish, and needs more people's deallocation to close and finishes, and has caused personnel's waste, and match ratio that the people is many simultaneously is difficult.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple and reliable semi-automatic box cupling that is used for the tubing and casing box cupling to be screwed in advance at shortcoming of the prior art to put, it can overcome manually-operated defective, satisfy the requirement in the production process, shorten the working time simultaneously, improved output.
Adopt following technical scheme for solving technical problem of the present invention:
A kind of semi-automatic box cupling is screwed in advance to be put, comprise base, one lift is set on the described base, 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 is provided with clamping plate.
Described floating shelf is made up of arm of force connecting plate, supporting plate, handrail, base plate and spring joint pin, two handrails vertically are set on the described base plate, described supporting plate is obliquely installed on base plate by handrail, described two blocks of supporting plates form " V " type, described arm of force connecting plate is arranged on the base plate both sides, the below of described base plate is provided with the spring joint pin, and described spring joint pin is sleeved in the spring.
The described arm of force is arranged on the floating shelf with the bearing pin connection.
Described base below is provided with roller, and described roller is arranged on the guide rail, and described guide rail setting on the ground.
The present invention adopts cylinder action in the clamping plate on the arm of force box cupling to be fixed on the floating shelf, and floating shelf connects the structure that is connected hoisting rack with lift by spring simultaneously.The lift of this structure can promote hoisting rack and move up and down to adapt to the box cupling of different tube diameters, and spring connects can make floating shelf seesaw up and down, twists smoothly with the center that makes things convenient for centering box cupling and tubing and casing to connect.Simultaneously roller is housed on base, entire equipment can be moved on guide rail, be used for estimating the aligning steel pipe.The present invention is that a kind of simple and reliable semi-automatic box cupling that is used for the tubing and casing box cupling is screwed in advance and puts, simple in structure, cost of manufacture is low, and is practical, goes slick, simple to operate, it has overcome manually-operated defective, has satisfied the requirement in the production process, has shortened the working time simultaneously, save the production cycle, improved output and production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the structural representation of floating shelf of the present invention.
The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, Fig. 3, shown in, a kind of semi-automatic box cupling is screwed in advance to be put, and 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.Fixedly be welded to connect a lift 7 on the base 8, the other end of lift 7 connects hoisting rack 6, and the guide post of hoisting rack 6 bottoms welding inserts in the guiding steel pipe on base 8 tops.Lift 7 can promote hoisting rack 6 and move up and down to adapt to the box cupling of 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 with the center that makes things convenient for centering box cupling and tubing and casing to connect.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.Vertical welding two handrail 2c on base plate 2d, supporting plate 2b tilts to be welded on the base plate 2d by handrail 2c, and two supporting plate 2b form " V " type, make things convenient for the placement of tubing and casing box cupling.The below welding spring joint pin 2e of base plate 2d, spring joint pin 2e is sleeved in the 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 connects 3, two arm of forces 3 of two arm of forces with bearing pin and is connected the upper end strap 1 of the arm of force 3 with the two ends of cylinder 4.Roller 10 is equipped with in base 8 belows, and roller 10 is installed in and fixes on the ground on the guide rail 9, and entire equipment can move on guide rail 9, is used for estimating the aligning steel pipe.
When the present invention works, promote hoisting racks 6 with lift 7 and move up and down and make box cupling well contact with floating shelf 2.Act on two arm of forces 3 by cylinder 4 again, make the clamping plate 1 that are fixed on the arm of force 3 upper ends produce masterpiece and be used for box cupling, thereby force box cupling to be fixed on the floating shelf 2.To connect steel pipe close toward waiting to twist with whole device by track 9 simultaneously, aims at screw thread, the steel pipe rotation, and box cupling begins pre-twisting.
