Description

Oil pipe conveying device for workover site Technical Field The invention relates to the technical field of oilfield workover, in particular to an oil pipe conveying device for a workover site. Background In the field of oilfield workover operation, an oil pipe is used as a core channel for connecting an underground oil layer with ground equipment, and the carrying, conveying and up-down drilling floor are indispensable and very frequent operation links in the workover process. Currently, most well servicing sites employ conventional modes of operation that are manually engaged with a crane or well servicing hoist. Specifically, firstly, the oil pipes need to be manually rolled to the lower part of a wellhead from a ground pipe bent frame, then the oil pipes are hung by using a steel wire rope sleeve, then the oil pipes are lifted by an operator command crane, the oil pipes are lifted to the upper part of a wellhead operation plane through the cooperative cooperation of a plurality of wellhead workers, the outer screw ends of the oil pipes are aligned to the lower well oil pipe inner screw openings, then the two oil pipes are screwed by an operator through tools, finally the oil pipes are pressed down by a hydraulic press at the top, the oil pipe is lowered, and the working flows of the oil pipe feeding and the oil pipe discharging are reversed. The traditional operation mode has the defects that the length of one standard oil pipe can reach almost ten meters, the weight is 95 kg, the manual work intensity is high when a worker pushes, pulls and rights the standard oil pipe, the whole process depends on the cooperation of multiple people and the frequent lifting of a crane, the delay of any one step can influence the whole operation progress, and the pursuit of modern well repair operation on the efficiency cannot be met. Disclosure of Invention The invention aims to provide an oil pipe conveying device for a well workover site, which aims to solve the problems of high manual work intensity and low overall operation efficiency in a manual operation mode. In order to achieve the above purpose, the basic scheme provided by the invention is as follows: the utility model provides an on-spot oil pipe conveyor of using of workover, includes base, support arm, adapter sleeve, clamping assembly and drive assembly, be equipped with on the base and be used for the support arm along the gliding sliding assembly of base surface, be equipped with the rotating assembly and the lifting assembly who are used for swivelling joint cover and lifting joint cover between adapter sleeve and the support arm respectively, be equipped with the support frame on the adapter sleeve, clamping assembly includes the adapter seat one, the adapter seat one can dismantle with the support frame and be connected, fixedly connected with supporting seat one on the adapter seat, it has two arc claws one that are used for holding oil pipe to articulate on the supporting seat one, every screw connection has two clamping sleeves on the arc claw one rolling connection has a plurality of ball between the clamping sleeve, every all articulate between arc claw one and the adapter seat one has the pneumatic cylinder first, drive assembly includes the adapter seat two, the adapter seat two can dismantle with the support frame and be connected, can dismantle on the adapter seat two arc claws two, every the inboard of arc claw two has been seted up and has been used for holding the arc groove two during the arc-shaped plate, every arc-shaped plate has two arc-shaped plate bearing two arc-shaped plate roll-shaped units to be equipped with two arc-shaped plate roll-shaped limiting units. The working principle of the invention is that the base of the whole device is stably placed between the wellhead and the ground pipe rack, and when the oil pipe is required to be discharged, an operator can position the clamping component and the driving component at the tail end of the support frame to be positioned above the proper position of the oil pipe by controlling the sliding component. The lifting assembly is started to drive the support frame to descend along the support arm, meanwhile, the two first hydraulic cylinders and the second hydraulic cylinders are controlled to shrink, the two first arc-shaped claws and the second arc-shaped claws are pulled to open, the limiting unit limits the arc-shaped plate to slide when the second arc-shaped claws are in an open state, the two first arc-shaped claws and the second arc-shaped claws are controlled to extend out after the two first arc-shaped claws and the second arc-shaped claws descend to hold the oil pipe, the two first arc-shaped claws are pushed to be closed, the oil pipe is firmly held tightly, and when the second arc-shaped claws are closed, the limiting unit releases the limitation of sliding of the arc-shaped plate, and meanwhile, when the oil pipe is held tightly by balls on the inner sides of the first ar
