Description

Technical Field

[0001] The utility model belongs to the field of sucker rod storage and transportation devices, in particular to a sucker rod recovery box. Background Art

[0002] At present, it is necessary to remove the sucker rods from the oil and water wells during minor repairs in oil fields. The sucker rods that have just been removed are usually placed in the open air on the oil pipe bridge next to the oil and water wells. Since there are many sucker rods in the oil and water wells, it is labor-intensive to manually place the sucker rods on the sucker rod rack. In addition, the residual oil on the sucker rods that have just been removed will pollute the surrounding environment. The sucker rods themselves will also age and rust due to wind, sun, and rain, affecting the service life of the sucker rods. When sending the sucker rods for repair, the manual handling method is labor-intensive and has high operating costs. The oil carried by the sucker rods dripping onto the road will also pollute the environment along the way.

[0003] In order to solve the above problems, there is a Chinese invention patent application with application publication number CN117905399A and application publication date April 19, 2024, which discloses an operating oil pipe box. The operating oil pipe box includes a box body, and an inlet and an outlet are respectively provided at the upper and lower positions of the front side of the box body. A pipe turning mechanism and a plurality of out-of-box guide plates are provided at the outlet. The pipe turning mechanism is used to prevent the oil pipe from rolling out of the box body and push the oil pipe out when it needs to be taken out. The out-of-box guide plate is used to guide the oil pipe to be discharged. An oil pipe bin is provided in the box body, and the front and rear inner walls of the oil pipe bin are provided with multi-layer cantilever bridge frames that are opposite to each other and staggered up and down. The multi-layer cantilever bridge frames form an S-shaped track that guides the oil pipe to move from top to bottom. A leakage hole is provided at the bottom of the oil pipe bin, and a dirt storage bin for receiving oil dirt dripping from the oil pipe is provided under the oil pipe bin in the box body. When the oil pipe is put in, the oil pipe enters the oil pipe bin from the inlet, rolls down on the S-shaped track, and is automatically arranged in a single row. After the oil pipe box with oil pipes is transported to the designated location, the guide plates are flipped one by one to make the guide plates perpendicular to the outer wall of the oil pipe box. The pipe flipping mechanism works to discharge the oil pipes arranged in a single row from the outlet one by one, and the oil pipes roll to the ground through the guide plates.

[0004] The cross section of each out-of-box guide plate of the above-mentioned operating oil pipe box is triangular, and one side of the triangle forms a guide slideway inclined from top to bottom. Each out-of-box guide plate is installed on a rotating shaft, and the rotating shaft is rotatably installed vertically in a sleeve connected to the outer wall of the oil pipe box, and the bottom surface of the out-of-box guide plate is at a certain height from the bottom surface. When not in use, the out-of-box guide plate is flipped to a position that fits the outer wall of the oil pipe box by rotating the rotating shaft one by one; when in use, the out-of-box guide plate is flipped to a position perpendicular to the outer wall of the oil pipe box by rotating the rotating shaft one by one, so that the oil pipe discharged from the inside of the oil pipe box rolls onto the guide plate, and then is guided to the ground by the out-of-box guide plate. The operation is cumbersome and affects the operation efficiency. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0030] The sucker rod recovery box of the utility model is further described in detail below in conjunction with the embodiments.

[0031] The storage and transportation of sucker rods are involved in minor repairs of oil and water wells. Generally, the sucker rods taken out from oil and water wells are placed in the open air on the ground or on oil pipe racks near the oil and water wells by manual labor. When they are sent for repair, they need to be transported by forklifts and trailers. The manual labor intensity is high, and the oil residue on the sucker rods dripping onto the ground during the placement and transportation process will pollute the surrounding environment and endanger the health of the workers.

[0032] In view of the above problems, the prior art proposes a technical solution, that is, by placing the oil pipe in the oil pipe box to achieve sealed storage and overall transportation of the oil pipe, the oil pipe box is provided with a dirt storage bin to collect the oil dirt remaining on the oil pipe. In the above technical solution, a plurality of out-of-box guide plates are provided at the outlet of the box body, and the out-of-box guide plates are connected to the box body through a rotating shaft vertically installed on the box body. When in use, the rotating shaft needs to be rotated one by one to adjust the posture of the out-of-box guide plates, which is cumbersome to operate.

[0033] In order to solve the problems existing in the above technical solutions, the sucker rod recovery box of the utility model is provided with a rotatable out-of-box guide frame at the outlet of the box body. The out-of-box guide frame is a whole. A locking assembly is provided between the out-of-box guide frame and the box body. When adjusting the posture of the out-of-box guide frame, only one operation is required to adjust the posture of the out-of-box guide frame. After adjustment, it is locked by the locking assembly to maintain its current posture.

[0034] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the front side of the box body 1 is provided with an inlet 101 and an outlet 102 for the sucker rod 8 to enter and unload. The inlet 101 and the outlet 102 are arranged vertically. The inlet 101 is provided with a box entry flap 301 for introducing the sucker rod 8 into the box body 1. The box entry flap 301 supports and guides the sucker rod 8 during the process of introducing the sucker rod 8 into the box body 1. Since the sucker rod 8 is relatively long, too few support points of the sucker rod 8 will cause the sucker rod 8 to bend under the action of its own weight. Therefore, the more the number of box entry flaps 301, the better the support for the sucker rod 8. Figure 2 and Figure 3 In the illustrated embodiment, the number of the box entry flaps 301 is 4, while in other embodiments, the number of the box entry flaps 301 may be 3 or 5 or other numbers to ensure that the sucker rod 8 can smoothly enter the box body 1.

[0035] Specifically, the box entry flap 301 has a second guide surface inclined from the outside of the box body 1 to the inside of the box body 1, so that the pumping rod 8 placed on the box entry flap 301 can automatically roll into the box body 1 by its own weight. The box body 1 is provided with a shaft sleeve 303, and a second rotating shaft 302 is vertically fixed on the box entry flap 301. The second rotating shaft 302 is arranged in the shaft sleeve 303. The box entry flap 301 is connected to the front side of the box body 1 through the second rotating shaft 302 and the shaft sleeve 303. When the pumping rod 8 is loaded, the second rotating shaft 302 can be rotated to fit the box entry flap 301 on the front side of the box body 1 to prevent the extended box entry flap 301 from scratching the staff. In other examples, the box entry flap 301 can also be connected to the box body 1 by other connection methods, such as by hinge connection.

[0036] Specifically, a guide plate 2 is provided on the front inner wall of the box body 1 corresponding to the box entry flap 301. The guide plate 2 is used to cooperate with the box entry flap 301 to guide the sucker rod 8 entering the inlet 101 of the box body 1 to the inside of the box body 1 and freely fall onto the cross bridge 6. In order to better play a guiding role, the guide plate 2 has a third guide surface adapted to the second guide surface, and the second guide surface and the third guide surface contact each other to form a guide slideway inclined from top to bottom. Figure 6 In the embodiment, the guide plate 2 is formed by butt-welding two round tubes. In other embodiments, the guide plate 2 may also be other structures such as a triangular steel plate, or the guide plate 2 may not be required, as long as the sucker rod 8 can smoothly enter the box body 1.

[0037] Specifically, in Figure 1 In the embodiment, a cross bridge 6 is provided in the box body 1, and the two ends of the cross bridge 6 are connected to the inner walls of the box body 1 on both sides. The cross bridge 6 is used to support the sucker rod 8 entering the box body 1. The cross bridge 6 and the upper part of the box body 1 constitute a storage part for storing the sucker rod 8, and the cross bridge 6 and the lower part of the box body 1 constitute a dirt storage tank 7 for receiving the oil dirt dripping from the sucker rod 8.

[0038] Specifically, in Figure 2 , Figure 4 and Figure 5 In the illustrated embodiment, the out-of-box guide frame includes a first rotating shaft 502 and a guide rib 501, wherein the first rotating shaft 502 is rotatably matched with the box body 1 to ensure that the posture of the out-of-box guide frame can be flexibly adjusted according to the use requirements. The guide rib 501 is fixedly assembled on the first rotating shaft 502, and the number of the guide ribs 501 is more than 2. When the out-of-box guide frame is in a blocking posture, the top of the guide rib 501 constitutes a blocking surface for blocking the pumping rod 8. When the out-of-box guide frame is in a flipped-out state, the top of the guide rib 501 constitutes a guiding slope for guiding the pumping rod 8 to be unloaded. The locking assembly for locking the out-of-box guide frame includes a crank arm 503 and a locking piece, wherein the crank arm 503 is arranged at the end of the first rotating shaft 502, and the locking piece is arranged between the box body 1 and the crank arm 503. When adjusting the posture of the out-of-box guide frame, the locking state of the locking piece is released, and the crank arm 503 is rotated to turn the out-of-box guide frame out to guide the sucker rod 8, thereby facilitating the unloading of the sucker rod 8. After the unloading of the sucker rod 8 is completed, the crank arm 503 is rotated again to retract the out-of-box guide plate into the box body 1.

[0039] Specifically, in Figure 5 In the illustrated embodiment, the locking member is composed of a latch 504, which is mounted on a crank arm 503. A latch hole that matches the latch 504 is provided at a corresponding position on the box body 1. When locking the out-of-box guide frame, the latch 504 is inserted into the latch hole on the box body 1. At this time, the latch 504 blocks the crank arm 503, and the crank arm 503 is fixedly connected to the out-of-box guide frame. After the latch 504 is locked, the out-of-box guide frame will maintain the current posture and will not move. When adjusting the posture of the out-of-box guide frame, it is only necessary to pull the latch 504 out of the latch hole and rotate the crank arm 503. The crank arm 503 drives the out-of-box guide frame to rotate, thereby adjusting the posture of the out-of-box guide frame.

[0040] In other embodiments, the locking assembly may also be other structures, such as providing a rotatable hook on the crank arm 503, and providing a gear lever at a corresponding position on the box body 1, and during the storage and transportation of the sucker rod 8, the hook is hung on the gear lever so that the out-of-box guide frame is in a vertical state to stop the sucker rod 8 in the box body 1; when the sucker rod 8 needs to be unloaded, the hook is rotated to disengage from the gear lever, and the out-of-box guide frame is automatically flipped out under the action of the deadweight of the sucker rods 8 stacked in the box body 1.

[0041] Specifically, in Figure 5In the illustrated embodiment, the guide rib 501 is a plate-type guide rib, and a guide slope is provided on the top thereof. The guide slope can facilitate the sucker rod 8 to roll out of the box 1. Under the action of its own potential energy, the sucker rod will still roll forward a certain distance after leaving the guide slope, so as to prevent the sucker rod 8 from being blocked at the outlet 102 after being unloaded from the box 1, thereby affecting the subsequent unloading of the sucker rod 8. The plate-type guide rib is in the shape of a triangle, and one of the hypotenuses of the triangle constitutes the guide slope. In other embodiments, the guide rib 501 can also be formed by butt welding two steel pipes, and together with the first rotating shaft 502, it constitutes a triangular guide frame. In another embodiment, the triangular plate can also be replaced by a trapezoidal plate, and the hypotenuse of the trapezoidal plate constitutes the guide slope.

[0042] Specifically, in Figure 1 In the embodiment shown, the inner end position of the out-of-box guide frame is not higher than the bottom surface of the pumping rod 8 of the box body 1 (at Figure 1 In the illustrated embodiment, the supporting bottom surface is a horizontal bridge 6), which facilitates the sucker rod 8 to automatically roll down to the guide slope of the out-of-box guide frame after the out-of-box guide frame is turned over, without blocking the sucker rod 8.

[0043] exist Figure 5 In the illustrated embodiment, a door panel 4 is also installed at the outlet 102. The door panel 4 is located outside the box guide frame. The door panel 4 is an upward-flipping door panel, which is used to prevent the oil residue on the pumping rod 8 from leaking from the gap between the box guide frame and the box body 1. A door holding component is provided between the door panel 4 and the box body 1. The door holding component is used to keep the door panel 4 open when the door panel 4 is opened. The door holding component is a door panel cable 401. The box body 1 is provided with a connecting structure that matches the door panel cable 401. The connecting structure can be a fixed ring or other structure. In other embodiments, the door holding component can also be a fixed hook, and the corresponding connecting structure on the box body 1 is a pull ring. When it is necessary to keep the door panel 4 open, the fixed hook is hooked on the pull ring.

[0044] Combining the above embodiments and Figure 7 , Figure 8 , Fig. 9 and Fig.10 The specific working process of the sucker rod recovery box of the utility model is as follows:

[0045] The sucker rod recovery box of the utility model is placed on the transport vehicle 9. During operation, the transport vehicle 9 with the sucker rod recovery box stops beside the wellhead 11, and the second rotating shaft 302 is rotated to adjust the box entry flap 301 to a position perpendicular to the front side of the box body 1. At this time, the box exit guide plate 501 is in the stop position. After the sucker rod 8 is taken out from the oil and water well, it is laid flat and directly lifted horizontally by the conveyor 10, and placed on the box entry flap 301. The sucker rod 8 rolls from the box entry flap 301 into the box body 1, and then is guided to the middle of the sucker rod bin by the guide plate 2 in the box body 1. The sucker rod 8 falls freely and accumulates on the cross bridge 6 at the bottom of the sucker rod bin. The oil and dirt remaining on the sucker rod 8 flows from the gap of the cross bridge 6 to the dirt storage bin at the bottom of the box body 1. The second rotating shaft 302 is rotated again to adjust the box entry flap 301 to fit the front side of the box body 1 to avoid scratching the box entry flap 301, and complete the rapid storage of the sucker rod 8. When the sucker rod 8 needs to be sent to the oil pipe factory for repair, the transport vehicle 9 transports the sucker rod recovery box with the sucker rod to the oil pipe factory. After the transport vehicle 9 arrives at the oil pipe factory, the sucker rod box on the transport vehicle 9 is placed in the unloading area by a crane, the door panel 4 is opened, and the door panel cable 401 is tied to the fixed ring, and the door panel 4 remains open. Then, the latch pin 504 on the crank arm 503 is pulled out, the first rotating shaft 502 is rotated, the box guide frame is turned out, and the sucker rods 8 piled in the sucker rod 8 box are quickly rolled out under the action of their own weight, completing the rapid unloading of the sucker rods 8.
