Description

Technical Field

[0001] This utility model relates to petroleum equipment, specifically a heat treatment device for sucker rods. Background Technology

[0002] After the sucker rod is manufactured, it needs to be heat-treated to increase its strength. Currently, during the heat treatment process, two workers fix the two ends of the sucker rod with pipe wrenches or hooks and slowly move through a high-frequency induction coil to heat the sucker rod. Then, the sucker rod is manually transferred to a quenching tank for quenching. The entire process is done manually, and if the two workers do not coordinate well, they are easily burned. In particular, when the sucker rod is lowered into the quenching tank, the small droplets of quenching liquid splashing when heated can easily burn the workers. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a heat treatment device for sucker rods. This device achieves the transfer, heating, and quenching of sucker rods through mechanization, thereby improving the efficiency of heat treatment and solving the problem of burns that can easily occur when manually transporting sucker rods.

[0004] The technical solution of this utility model is: a heat treatment device for sucker rod, including a quenching mechanism, a high-frequency induction heating mechanism and a conveying mechanism, wherein the high-frequency induction coil of the high-frequency induction heating mechanism is arranged at the conveying track of the conveying mechanism.

[0005] The quenching mechanism includes a quenching pool with an inclined inner bottom surface. The rear end of the quenching pool is provided with a receiving slope for receiving the sucker rod conveyed by the conveying mechanism. A flap is provided on the quenching pool at the receiving slope to limit the sucker rod. Both ends of the flap are connected to a tilting cylinder.

[0006] The quenching pool has vertical grooves at both bottom corners, and a slider is slidably connected in the vertical groove. The top of the slider is an inclined plane with the same slope as the bottom surface of the quenching pool. The quenching pool has vertical guide grooves on both sides that communicate with the adjacent grooves. A lifting rod is slidably connected in the vertical guide groove. The bottom of the lifting rod is fixedly connected to the slider, and the top of the lifting rod is connected to the lifting end of the lifting cylinder through a connecting plate. The lifting cylinder is fixed on the outer wall of the quenching pool.

[0007] Preferably, the front end of the quenching tank is provided with a material discharge slope.

[0008] Preferably, the conveying mechanism includes a frame, on which a set of conveying wheels is rotatably mounted. One side of the set of conveying wheels is connected to a set of sprockets and a chain for transmission. The frame is also equipped with a motor that drives one of the sprockets to rotate.

[0009] Compared with the prior art, this utility model has the following advantages: The structure of this utility model is simple and reasonable. It realizes the transmission, heating and quenching of sucker rods through mechanization, and performs heating treatment at the same time as transmission, which improves work efficiency and reduces manual labor intensity. During quenching, the sucker rod immersed in the quenching pool is lifted out of the quenching liquid through mechanization, which is safer and more reliable, and effectively avoids the problem of scalding from splashing quenching liquid in traditional operations.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0016] like Figures 1 to 3 A heat treatment device for sucker rods includes a quenching mechanism 1, a high-frequency induction heating mechanism 2, and a conveying mechanism 4. The high-frequency induction coil 3 of the high-frequency induction heating mechanism 2 is arranged at the conveying track of the conveying mechanism 4.

[0017] The quenching mechanism 1 includes a quenching pool 5 with its inner bottom surface arranged at an inclination. The rear end of the quenching pool 5 is provided with a receiving slope 11 for receiving the sucker rod conveyed by the conveying mechanism 4.

[0018] The quenching pool 5 is provided with a flap 13 at the receiving slope 11 to limit the sucker rod. The flap 13 is provided with a flipping cylinder 12 at both ends. The flipping cylinder 12 is fixed on the quenching pool 5 and the rotating end of the flipping cylinder 12 is connected to the flap 13. The flap 13 is driven to rotate by the flipping cylinder 12.

[0019] Vertical grooves 15 are provided at both bottom corners of the quenching pool 5. A slider 10 is slidably connected in the vertical grooves 15. The top of the slider 10 is an inclined surface with the same slope as the bottom surface of the quenching pool 5.

[0020] Both sides of the quenching pool 5 are provided with vertical guide grooves 14 that communicate with the adjacent slide grooves. A lifting rod 9 is slidably connected in the vertical guide groove 14, and the bottom of the lifting rod 9 is fixedly connected to the slider 10.

[0021] The top of the lifting rod 9 is connected to the lifting end of the lifting cylinder 8 through the connecting plate 7. The lifting cylinder 8 is fixed on the outer wall of the quenching pool 5. When the lifting cylinder 8 extends or retracts, it drives the slider 10 to move up and down through the connecting plate 7 and the lifting rod 9.

[0022] Working principle: When in use, the sucker rod is conveyed to the receiving slope 11 of the quenching tank 5 through the conveying mechanism 4. During the conveying process, the sucker rod is heated through the inner hole of the high-frequency induction coil 3 and then conveyed to the receiving slope 11.

[0023] By controlling the tilting cylinder 12 to drive the tilting plate 13 to rotate, the sucker rod on the receiving slope 11 rolls down along the bottom surface of the quenching pool 5 to the two bottom corners of the quenching pool 5, and at the same time, the liquid in the quenching pool 5 is used for quenching treatment.

[0024] Then, the lifting cylinder 8 drives the slider 10 to rise, and the top of the slider 10 supports the sucker rod to rise, thus lifting the quenched sucker rod out of the quenching pool 5.

[0025] In addition, a discharge slope 6 can be set at the front end of the quenching tank 5. When the slider 10 lifts the sucker rod to the discharge slope 6, the sucker rod can roll down along the discharge slope 6 to be collected. Example 2

[0026] This embodiment is a further optimization based on the above embodiment, specifically:

[0027] like Figure 4 The conveying mechanism 4 includes a frame 20, on which a set of conveying wheels 17 are rotatably mounted. One side of the set of conveying wheels 17 is connected by a set of sprockets 18 and a chain 19.

[0028] A motor 16 is installed on the frame 20. The motor 16 drives one of the sprockets 18 to rotate, and the sprocket 18 drives the other sprockets 18 to rotate together through the chain 19, thereby driving all the transmission wheels 17 to rotate synchronously and transmit the sucker rod.

[0029] This utility model has a simple and reasonable structure. It completes the transfer, heating and quenching of sucker rods in a mechanized manner, thereby improving work efficiency and solving the problem of easy burns caused by traditional manual transfer of sucker rods.

[0030] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
