[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] See also Figure 1 The present invention provides a technical solution: a pipe conveyor for oil well drilling and repairing operations, comprising a catwalk 100 for temporarily storing and conveying oil pipes; a pipe rack 200, which is arranged outside one side of the catwalk 100 and is used to orderly store spare oil pipes or used oil pipes; a recovery pipe rack 300, which is erected above the pipe rack 200 and is used to recover used oil pipes; an intermittent loading and unloading mechanism 400, which is fixedly installed between the pipe rack 200 and the catwalk 100 and is used for automatic loading of spare oil pipes or automatic unloading of used oil pipes; a transition mechanism 500, which is erected between the intermittent loading and unloading mechanism 400 and the pipe rack 200 and is used for transferring spare oil pipes or used oil pipes.

[0055] Based on the above-mentioned structural setting, the pipe conveyor for oil well drilling and repairing operation is composed of a catwalk 100, a pipe rack 200, a recovery pipe rack 300, an intermittent loading and unloading mechanism 400 and a transition mechanism 500. The intermittent loading and unloading mechanism 400 is installed between the catwalk 100 and the pipe rack 200, and is used for batch automatic loading of spare oil pipes and the batch automatic unloading of used oil pipes. The transition mechanism 500 is used for the material transfer operation between the oil pipes on the intermittent loading and unloading mechanism 400 and the pipe rack 200 and the recovery pipe rack 300, respectively. The spare oil pipes can be transferred from the pipe rack 200 to the intermittent loading and unloading mechanism through the transition mechanism 500. The used oil pipe rods can be transferred from the intermittent loading and unloading mechanism 400 to the recovery pipe rack 300 through the transition mechanism 500. Specifically, during the working process, it is divided into a loading link and a unloading link. In the loading link, the spare oil pipe rods are transferred from the pipe rack 200 to the intermittent loading and unloading mechanism 400 one by one with the help of the transition mechanism 500. Each time the intermittent loading and unloading mechanism 400 moves once, a material transfer action is completed until the spare oil pipe rods transferred for the first time are transported to the catwalk 100. Thereafter, each time the intermittent loading and unloading mechanism 400 moves once, in cooperation with the transition mechanism 500, the spare oil pipe rods can be transferred to the recovery pipe rack 300. Similarly, in the unloading link, the intermittent loading and unloading mechanism 400 moves in the reverse direction. When the used oil pipe rod is mounted on the catwalk 100, the used oil pipe rod can be removed by the intermittent loading and unloading mechanism 400. Subsequently, each time the intermittent loading and unloading mechanism 400 moves, a material removal operation is completed until the used oil pipe rod moves to the input end of the intermittent loading and unloading mechanism 400. At this time, with the help of the transition mechanism 500, the used oil pipe rod can be lifted to the recovery pipe rack 300 for output, and finally fall back into the pipe rack 200. After that, each time the intermittent loading and unloading mechanism 400 moves, in cooperation with the transition mechanism 500, it can be realized. The continuous recovery of oil pipe rods has been used. The pipe rod conveyor for oil drilling and repairing operations can realize batch automatic material transfer of oil pipe rods by providing an intermittent loading and unloading mechanism 400. Compared with the existing pipe rod conveying device that can only complete the material transfer operation of a single oil pipe rod in a single action, the return time is greatly reduced, that is, when the previous pipe rod is conveyed to the target position, the subsequent pipe rod is ready and can be directly transported for the next time, effectively ensuring the continuity and efficiency of the operation mode. At the same time, with the help of the transition mechanism 500, the pipe rack 200 can store both spare oil pipe rods and used pipe rods, greatly saving floor space.

[0056] For further information, see Figure 5The pipe rack 200 is composed of a first frame 210 and a plurality of support rods 220 erected on the top of the inner side of the first frame 210 for supporting and arranging the oil pipe rods along the inclined direction. Among them, spare oil pipe rods or used oil pipe rods can be arranged and stored in an orderly manner, and the used oil pipe rods can be dropped back onto the pipe rack 200 through the recovery pipe rack 300.

[0057] For further information, see Fig.10 and Fig.11 The recovery pipe rack 300 includes a support plate 320 fixedly mounted on a plurality of support rods 220 through a second frame 310, and two inclined support platforms 330 for directional unloading of used oil pipe rods are fixedly mounted on the support plate 320. The second frame 310 cooperates with the support plate 320 to provide structural support for the erection of the two inclined support platforms 330, and the inclined surfaces of the two inclined support platforms 330 realize the rolling unloading of used oil pipe rods.

[0058] For further information, see Figure 2 and Figure 3The intermittent loading and unloading mechanism 400 is composed of a third frame 410 and three reciprocating lifting assemblies 420 fixedly installed on the top of the third frame 410 at equal intervals. The reciprocating lifting assembly 420 includes a base plate 4210 and a plurality of fixed brackets 4230 fixedly mounted on the top of the base plate 4210 through a mounting frame 4220. The plurality of fixed brackets 4230 are parallel to each other and a movable bracket 4240 is parallelly mounted between any two adjacent fixed brackets 4230. The top of the base plate 4210 is slidably equipped with a slide seat. 4250, and a first translation cylinder 4260 for movement of the slide 4250 is fixedly installed on one side of the slide 4250, two first lifting cylinders 4270 are vertically fixedly installed on the top of the slide 4250, a connecting plate 4280 for assembly of the bottom of the movable bracket 4240 is fixedly installed between the output ends of the two first lifting cylinders 4270, and a plurality of V-grooves 4290 are provided on the tops of the fixed bracket 4230 and the movable bracket 4240 at equal intervals for accommodating a single oil pipe rod. The intermittent loading and unloading mechanism 400 realizes the intermittent feeding of the oil pipe rod by means of three reciprocating jacking assemblies 420. Specifically, taking the feeding of the spare oil pipe rod as an example, in the reciprocating jacking mechanism, when the transition mechanism 500 moves a spare oil pipe rod to the intermittent loading and unloading mechanism 400, first, the output end of the first translation cylinder 4260 is in an extended state, and the output ends of the two first jacking cylinders 4270 rise, and the spare oil pipe rod can be loaded by means of the V-shaped groove 4290 on the movable bracket 4240. The oil pipe rod is separated from the fixed bracket 4230, and then the output end of the first lifting cylinder 4270 retracts until the spare oil pipe rod moves to above the next V-groove 4290 on the fixed bracket 4230. At this time, the output ends of the two first lifting cylinders 4270 retract until the spare oil pipe rod is limited and placed in the V-groove 4290 on the fixed bracket 4230. The above is a single action of the reciprocating lifting assembly 420. Repeat the above actions until the spare oil pipe rod is transported to the catwalk 100.

[0059] For further information, see Figure 6-9 The transition mechanism 500 includes a slide 520 that is lifted and lowered by a second lifting cylinder 510, a guide plate 530 that is slidably mounted on the top of the slide 520 along the length direction of the slide 520, and a second translation cylinder 540 that is fixedly mounted on the outside of one side of the slide 520 for the guide plate 530 to move. A notch 5310 that can be used to support a single spare oil pipe rod is provided on the top of the guide plate 530 away from the catwalk 100. The bottom surface of the notch 5310 is provided with a loading slope 5320 that can be used to directional roll the spare oil pipe rod. The top of the guide plate 530 is provided with a unloading slope 5330 that can be used to directional roll the used oil pipe rod. The transition mechanism 500 has two working states, specifically, as follows: Figure 8 and Fig. 9 As shown, in the first working state, that is, Figure 8 As shown, it is the feeding state. At this time, the output end of the second translation cylinder 540 is in an extended state. With the rise of the output end of the second lifting cylinder 510, a single spare oil pipe rod can be lifted up with the help of the feeding slope 5320, and the spare oil pipe rod rolls along the feeding slope 5320 to the notch 5310. Then the output end of the second lifting cylinder 510 retracts, and the spare oil pipe rod is limited and placed in the first V-shaped groove 4290 of the fixed bracket 4230, completing the material transfer operation of the spare oil pipe rod from the pipe rack 200 to the intermittent loading and unloading mechanism 400. In the second working state, that is, Fig. 9 As shown, it is a material unloading state. At this time, the output end of the second translation cylinder 540 is in a contracted state. With the rise of the output end of the second lifting cylinder 510, the used oil pipe rod in the first V-shaped groove 4290 of the fixed bracket 4230 can be lifted up with the help of the unloading slope 5330, and the used oil pipe rod rolls along the unloading slope 5330 to the recovery pipe rack 300, completing the material transfer operation of the used oil pipe rod from the intermittent loading and unloading mechanism 400 to the recovery pipe rack 300.

[0060] For further information, see Figure 4 , further comprising a first guide column 550 vertically fixedly installed at the bottom of the slide 520, and a first guide sleeve 560 for the first guide column 550 to pass through is fixedly installed on the inner side of the third frame 410. Among them, the second lifting cylinder 510 is fixedly installed in the first frame 210 along the vertical direction, and the slide 520 is set between the first frame 210 and the third frame 410. As a preferred embodiment, the first guide column 550 and the first guide sleeve 560 that are adapted to each other are provided to ensure the stability of the slide 520 in lifting and lowering.

[0061] For further information, see Fig.10 and Fig.12 , and also includes two symmetrically distributed limiting assemblies 600 respectively installed on both sides of the second frame 310 for aligning the ends of the oil pipe rods. The limiting assembly 600 includes a fixed plate 610 and a baffle 620 parallel to the inner side of the fixed plate 610. A screw rod 630 is vertically threaded through the fixed plate 610. The inner end of the screw rod 630 is rotatably connected to the baffle 620. A hand wheel 640 is fixedly installed on the outer end of the screw rod 630. Second guide columns 650 are vertically fixedly installed on the outer side of the baffle 620 and on both sides of the screw rod 630. Two second guide sleeves 660 are fixedly installed on the second frame 310, and two second guide columns 650 can be respectively passed through by the second guide sleeves 660. Among them, the limiting assembly 600 is used to limit the ends of the oil pipes and rods when they are arranged in an orderly manner to ensure that the ends are aligned. As a preferred embodiment, with the help of the screw 630 and the second guide column 650 and the second guide sleeve 660 that adapt to each other, it is helpful for the operator to adjust the position of the baffle 620 in real time, and it can adapt to the alignment operation of oil pipes and rods of various lengths and specifications.

[0062] For further information, see Fig.10 and Fig.13 , and also includes a material blocking assembly 700 mounted on the output ends of the two inclined support platforms 330 and fixedly mounted on the inner side of the top of the first frame 210. The material blocking assembly 700 includes a vertical plate 710, the top of the inner side of the vertical plate 710 is covered with a rubber pad 720, and both sides of the outer side of the vertical plate 710 are fixedly mounted with a lifting cylinder 730 erected in the vertical direction, and the output ends of the two lifting cylinders 730 are fixedly mounted with a block 740 extending to the inner side of the vertical plate 710. Among them, the material blocking assembly 700 is used to provide buffer support for the used oil pipe rods being discharged. The rubber pad 720 can effectively reduce the impact force of the used oil pipe rods rolling downward. In addition, with the help of the block 740 driven by the lifting cylinder 730, a switch structure can be formed at the discharge port to further reduce the impact of the used oil pipe rods falling, and at the same time, it is helpful for the orderly discharge of the used oil pipe rods.
