Technical Field

[0001] The present invention relates to the field of pipe materials, and particularly to a pipe hoisting and discharging device. Background Art

[0002] All kinds of pipe materials in the existing oil industry sites need to be neatly arranged on pipe racks. The discharging is carried out by hoisting and transferring with a crane. During the operation process, 1 hoisting commander and 2 porters need to cooperate with each other. For each pipe material, 2 cooperating personnel need to hang the hooks on the water eyes at both ends of the pipe material under the command of the hoisting commander respectively, and after hoisting to the designated position, align the male thread end of the pipe material.

[0003] The operation process is completed by 3 people, resulting in waste of human resources. During the operation process, since the object being hoisted is suspended in the air, the object will swing, and there is a safety risk of falling. During the process of lowering the lifting body, personnel must align specific parts, and there are safety risks of pinching hands or falling easily due to excessive force or during the lowering process. Summary of the Invention

[0004] The present invention provides a pipe hoisting and discharging device, which solves the problem that several labors are needed for cooperative operation during the standardized stacking of pipe materials, and there are certain risks, and realizes that the angle adjustment of the pipe materials can be carried out through centralized control by the operator, so as to meet the standard of neat stacking.

[0005] The technical problem solved by the present invention can be realized by adopting the following technical solutions: A pipe hoisting and discharging device includes a crane and the boom of the crane, and further includes: A connecting frame, which is detachably connected to the front end of the boom; A suspension rod, the top end of which is hinged to the connecting frame; An adjusting part, which is detachably connected to the bottom end of the suspension rod; A picking part, which is detachably connected to the bottom end of the adjusting part; A limiting die, which is detachably connected to the bottom of the picking part. Further, a hinge seat is detachably connected to the lower surface of the front end of the boom, a small arm hydraulic cylinder is hinged to the hinge seat, an ear plate is detachably connected to the side of the suspension rod, and the other end of the small arm hydraulic cylinder is hinged to the ear plate.

[0006] Further, the suspension rod is composed of a plurality of square pipes sleeved with decreasing sizes in sequence, and positioning pins are inserted on each stage of the square pipes.

[0007] Further, the adjusting part includes a flange plate and a speed reduction adjusting mechanism. The bottom end of the suspension rod is vertically and detachably connected to the center of the upper surface of the flange plate, the speed reduction adjusting mechanism is detachably connected to the lower surface of the flange plate, and the picking part is detachably connected to the driving end of the speed reduction adjusting mechanism.

[0008] Further, the picking part includes a rotating frame and a pair of magnetic attraction parts. The rotating frame is detachably connected to the driving end of the speed reduction and adjustment mechanism. A pair of the magnetic attraction parts are detachably connected to both sides of the lower surface of the rotating frame. The limiting die is detachably connected to the adsorption surface at the bottom end of the magnetic attraction part.

[0009] Further, the magnetic attraction part is a permanent magnet lifter. The permanent magnet lifters are respectively detachably connected to both ends of the lower surface of the rotating frame. The limiting die is detachably connected to the adsorption surface of the permanent magnet lifter.

[0010] Further, a swing hydraulic cylinder bracket is detachably connected to one side of the permanent magnet lifter. A swing hydraulic cylinder is detachably connected to the swing hydraulic cylinder bracket. The driving end of the swing hydraulic cylinder is connected to the control rotating shaft of the permanent magnet lifter.

[0011] Further, the limiting die is composed of a pair of limiting blocks. The pair of limiting blocks are detachably connected to the front and rear sides of the adsorption surface of the permanent magnet lifter, and arc surfaces are formed on the opposite surfaces of the pair of limiting blocks.

[0012] The beneficial effects of the present invention are as follows: Due to the adoption of the permanent magnet lifter, it effectively solves the problem of adsorbing pipes in a specially restricted environment, and thus realizes magnetic attraction without electricity.

[0013] Due to the adoption of the swing hydraulic cylinder, it effectively solves the problem that the permanent magnet lifter needs to be manually controlled for magnetic attraction. Through the forward and reverse rotation of the swing hydraulic cylinder, the automation of magnetization and demagnetization of the permanent magnet lifter is effectively solved.

[0014] Due to the adoption of the forearm hydraulic cylinder, it effectively solves the problem that the angle of the hanging rod always remains vertically downward. Through the telescopic movement of the forearm hydraulic cylinder, the angle adjustment of the hanging rod can be controlled, and at the same time, the swing of the hanging rod is limited.

[0015] Due to the adoption of the speed reduction and adjustment mechanism, it effectively solves the problem that the overall shaking or falling off may occur due to too fast speed during the rotation of the pipe, and thus realizes the problems of pipe swing and speed control, and achieves stable adjustment.

[0016] Due to the adoption of the limiting die, it effectively solves the problem that the pipe rolls when adsorbed by the permanent magnet lifter. The pipe can be limited by the limiting die, so that there will be no error when adjusting the pipe. Due to the adoption of detachable connection, the distance between the appropriate limiting dies can be adjusted according to different pipe sizes, so as to adapt to pipes of different sizes.

Detailed implementation manners

[0022] Embodiment 1: Referring to Figure 1-2 , it is a schematic structural view of Embodiment 1 of the present invention. A pipe hoisting and discharging device includes a crane 1 and the boom 2 of the crane, and further includes: A connecting frame 3, which is detachably connected to the front end of the boom 2; A hanging rod 4, the top end of which is hinged to the connecting frame 3; An adjusting part, which is detachably connected to the bottom end of the hanging rod 4; A picking part, which is detachably connected to the bottom end of the adjusting part; A limit die 5, which is detachably connected to the bottom of the picking part.

[0023] During actual use: The crane 1 drives the connecting frame 3 through the boom 2 to control the moving direction of the hanging rod 4, so that the hanging rod 4 drives the adjusting part and the picking part to move above the pipe. Then, further control is carried out to make the limit die 5 dock with the pipe. Then, the pipe is grabbed by the picking part. Then, by controlling the hanging rod 4 to rise, the crane 1 controls the rotation and translation to the placing position. Then, by controlling the picking part to release the grab on the pipe, the pipe can be placed, and the stacking of the pipe is completed.

[0024] In this embodiment, a sensor is arranged at the rotating position, so that the adjustment of the angle can be controlled through the sensor signal.

[0025] Embodiment 2: Referring to Figure 1-2 , the difference in this embodiment is that: a hinge seat 6 is detachably connected to the lower surface of the front end of the boom 2, a small arm hydraulic cylinder 7 is hinged on the hinge seat 6, an ear plate 8 is detachably connected to the side of the hanging rod 4, and the other end of the small arm hydraulic cylinder 7 is hinged to the ear plate 8.

[0026] During actual use: The small arm hydraulic cylinder 7 is hinged to the hanging rod 4 and the boom 2. By the telescopic movement of the small arm hydraulic cylinder 7, the included angle between the hanging rod 4 and the boom 2 is controlled, so as to control the hanging rod 4 to remain vertical.

[0027] Monitor the vertical angle change of the suspension rod 4 through a sensor and control the change angle to ±2°.

[0028] Embodiment 3: Refer to Figure 1-2 In this embodiment, the difference is that the suspension rod 4 is composed of a plurality of square pipes with gradually decreasing sizes sleeved together, and positioning pins 9 are inserted on each stage of the square pipes.

[0029] During actual use: By using the sleeved square pipes in cooperation with the positioning pins, the length of the suspension rod 4 can be adjusted, which is convenient for use in different terrains.

[0030] In this embodiment, it also includes the steel rope of the crane. The end of the steel rope is detachably connected to the square pipe at the lowest stage of the suspension rod 4, and the steel rope is located inside the suspension rod 4.

[0031] During use, release the limit of the positioning pin 9 and operate through the hydraulic operating rod on the crane 1. Push the operating rod forward to release the steel rope, and the suspension rod 4 extends downward. Pull the operating rod backward, the steel rope retracts, and the suspension rod retracts.

[0032] Since the square pipe sleeve combination is used as the main body of the suspension rod 4, it can prevent natural swing caused by uneven stress during pipe lifting.

[0033] Embodiment 4: Refer to Figure 1-2 In this embodiment, the difference is that the adjusting part includes a flange 10 and a speed reduction adjusting mechanism 11. The bottom end of the suspension rod 4 is vertically and detachably connected to the center of the upper surface of the flange 10. The speed reduction adjusting mechanism 11 is detachably connected to the lower surface of the flange 10, and the picking part is detachably connected to the driving end of the speed reduction adjusting mechanism 11.

[0034] During actual use: The speed reduction adjusting mechanism 11 is a disc-type speed reduction structure, in the shape of a disc. The bottom is a driving disc, which is equipped with a driving motor. The driving motor can be hydraulically driven or electrically driven, and it meshes with the speed reduction adjusting mechanism to control the rotation of the driving end of the speed reduction adjusting mechanism 11.

[0035] When rotating, it drives the picking part to rotate horizontally, thereby adjusting the horizontal angle of the pipe to meet the requirement of neat stacking.

[0036] This embodiment adopts a disc-type speed reduction adjusting mechanism 11, which has a large rotating connection surface. When picking up the pipe, due to the picking part not being in the middle of the pipe causing center offset, the driving disc can effectively resist the excessive wear caused by the center offset.

[0037] Embodiment 5: Refer to Figure 1-3, The difference in this embodiment is that: the picking part includes a rotating frame 12 and a pair of magnetic adsorption parts. The rotating frame 12 is detachably connected to the driving end of the speed reduction and adjustment mechanism 11. A pair of the magnetic adsorption parts are detachably connected to both sides of the lower surface of the rotating frame 12. The limiting die 5 is detachably connected to the adsorption surface at the bottom end of the magnetic adsorption part.

[0038] During actual use: through the transfer of the rotating frame 12, a pair of magnetic adsorption parts are located on both sides of the rotating frame 12, increasing the distance between the pair of magnetic adsorption parts, thereby improving the stability of grasping, preventing the center of gravity from shifting during the grasping of the pipe and causing it to fall off, and improving the stability of adsorption.

[0039] Embodiment 6: Refer to Figure 2 , The difference in this embodiment is that: the magnetic adsorption part is a permanent magnet lifter 13. The two ends of the lower surface of the rotating frame 12 are respectively detachably connected to the permanent magnet lifter 13. The limiting die 5 is detachably connected to the adsorption surface of the permanent magnet lifter 13.

[0040] During actual use: dock with the pipe through the limiting die 5, then adsorb the pipe through the permanent magnet lifter 13, and then it can be transferred and carried. The limiting die 5 can prevent the pipe from rolling on the adsorption surface of the permanent magnet lifter 13, thereby preventing the pipe from falling off.

[0041] Embodiment 7: Refer to Figure 2 , The difference in this embodiment is that: a swing hydraulic cylinder bracket 14 is detachably connected to one side of the permanent magnet lifter 13. A swing hydraulic cylinder 15 is detachably connected to the swing hydraulic cylinder bracket 14. The driving end of the swing hydraulic cylinder 15 is connected to the control rotating shaft of the permanent magnet lifter 13.

[0042] During actual use: the swing hydraulic cylinder 15 can provide high-torque rotation, thereby achieving hydraulic control and realizing the linkage control of the pipe adsorption and detachment with the crane hydraulic system.

[0043] Embodiment 8: Refer to Figure 3 , The difference in this embodiment is that: the limiting die 5 is composed of a pair of limiting blocks. A pair of the limiting blocks are detachably connected to the front and rear sides of the adsorption surface of the permanent magnet lifter 13, and arc surfaces are opened on the opposite surfaces of the pair of limiting blocks.

[0044] During actual use: the limiting die 5 restricts the rolling of the pipe. At the same time, the arc surface can reduce the hard friction of the limiting die on the pipe, prevent deep scratches on the pipe surface, and improve the stability during the adsorption of the pipe.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention, and all of them are within the protection scope of this technology.
