Description

Technical Field

[0001] The invention relates to petroleum mechanical equipment, in particular to an automatic oil pipe cashier device. Background Art

[0002] At present, there are two situations for the cashing out of oil pipes (up and down drilling) in the field of well repair in oilfield well sites: one is that there is no well repair catwalk, and the oil pipes are basically stacked manually by hand and shoulder. This scenario depends entirely on the standardized implementation of process discipline and system, and requires many people, occupies a large area, and is time-consuming and laborious. The second is that there are two forms of scenarios where well repair catwalks are used: one is the situation where there is no cashier cabinet, which is similar to the previous one, and the other is the situation where there is oil pipe cashier equipment, which is a hanging magnetic suction structure. The main problem of this method is that it occupies a large area, moves slowly, and has low efficiency. This is currently the best. In response to the current situation, the oil pipe cashier cabinet was designed and invented to mainly solve the problem of automatic accumulation and stacking of oil pipes. Summary of the invention

DETAILED DESCRIPTION

[0013] The automatic oil pipe cashier device of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0014] The oil pipe automatic teller cabinet of the present invention, see Figures 1 to 8 , including a base 1, on which at least two pulleys 3 are arranged, the pulleys 3 can move on the base 1, and the movable slide 2 is arranged on the pulleys 3. The piston rod of the lifting cylinder 14 arranged on one side of the base 1 is connected to the movable slide 2 corresponding to the side, and a guide bracket 9 is arranged on the movable slide 2 on the side. Guide columns 13 are respectively arranged on both sides of the lifting cylinder 10 on the base 1, each guide column 13 passes through the movable slide 2 and extends into the corresponding guide column sleeve 15 on the guide bracket 9, and the extension and retraction of the piston rod of the lifting cylinder 10 can make the movable slide 2 tilt under the movement of the pulley 3. A left side plate 8 is provided at the left end of the guide bracket 9, and a right side plate 11 is provided at the right end of the guide bracket 9. A plurality of tilting cylinders 12 are provided side by side on the left side plate 8 and the right side plate 11, respectively. A stopper 4 is hinged to the piston rod end of each tilting cylinder 12. When the plurality of stoppers at the left side plate 8 are laid flat, their heights are staggered in sequence and stacked. Similarly, when the plurality of stoppers at the right side plate 11 are laid flat, their heights are staggered in sequence and stacked. A hoist 7 is provided at both ends of the other side of the movable slide 2, respectively. The hoist 7 includes a bracket 19, two upper sprocket wheels 18 are provided at the upper end of the bracket 19, and two lower sprocket wheels 20 are provided at the lower end of the bracket 19. The upper sprocket wheels 18 are connected to the corresponding lower sprocket wheels 20 by chains 21, and hooks 6 are provided on the two chains 21. The lower sprockets 20 at the lower ends of the two hoist brackets are connected through a rotating shaft 22, and the driving motor 25 is connected to the driving wheel 23 at the end of the rotating shaft 22 through a driving chain 24. The driving motor 25 drives the chain 21 to rotate through the rotating shaft 22, thereby driving the hook 6 to move up and down along the chain 21.

[0015] The present invention provides a cushion block 16 at the bottom of each baffle rod 4 away from the corresponding turning cylinder. When the baffle rod 4 at the left plate 8 or the right plate 11 is in a flat position, the cushion block at the end of the upper baffle rod contacts the end of the lower baffle rod. In this way, when multiple baffle rods on the same side are laid flat, their heights are staggered in sequence to form a stacked state. The gap between the upper and lower baffle rods is used to store multiple oil pipes 28, thereby realizing multi-layer accumulation of the oil pipes 28. The present invention also fills the baffle rod 4 with a rubber block 17, which can solve the problem of multi-layer accumulation error of the oil pipe.

[0016] The present invention also provides an adapter 5 beside each hoist 7, see Fig. 9 The adapter 5 is provided with an inclined support 27 on a support platform 26, and a stopper is provided at the lower end of the inclined support 27, which is used to prevent the oil pipe from sliding down.

[0017] The present invention drives the movable slide to tilt under the action of the pulley 3 through the action of the lifting cylinder 10, so that the entire device can be tilted to form two working positions of upper drilling and lower drilling. The ramp principle is adopted to realize the automatic cashiering of the oil pipe 28 by the natural rolling of the oil pipe 28, and the hook realizes the turning of the oil pipe at the top of the chain 21.

[0018] The present invention adopts a controller to control the actions of the driving motor 25, the lifting cylinder 10, the turning cylinder 12 and other components of the hoist 7, so as to realize the automatic up-drilling and down-drilling of the oil pipe.

[0019] The present invention is prepared for drilling work, see Fig.10 First, check the installation direction of the hook 6, the position of the adapter 5 and the position of the stopper 4. Then, start the machine to automatically check the status of each working position. After completion, prepare for drilling work.

[0020] The present invention works by drilling, see Fig.11 When drilling, the oil pipe 28 placed on the adapter 5 is continuously lifted and placed into the first layer of the device through the hook 6 on the hoist 7. After the first layer is full, the two corresponding flip cylinders 12 on the left plate 8 and the right plate 11 flip into place, and the corresponding two blocking rods 4 are located above the oil pipe 28. At this time, the second layer is laid. And so on. After all the oil pipes are drilled, the lifting cylinder 10 makes the movable slide in a horizontal state. See Fig.12 shown. The present invention is prepared for drilling work, see Fig.13 First, adjust the installation direction of the hook 6, adjust the position of the adapter 5 and the position of the stop rod 4, lift the lifting cylinder 10 into place, automatically check that each part is in working condition, and start drilling.

[0021] The present invention works by drilling down, see Fig.14, the top layer of the device oil pipe is lifted by the hoist 7 one by one into the adapter 5 preparation position, after the first layer of drilling is completed, the corresponding turning cylinder 12 on the left plate 8 and the right plate 11 swings, and the corresponding blocking rod 4 enters the vertical position, and the second layer of drilling is carried out, and so on, when all the oil pipes enter the oil well, the work is completed.
