Description

Technical Field

[0001] This utility model relates to a surface treatment fixing bracket for oil extraction rods and pipe fittings, belonging to the field of petroleum machinery processing technology. Background Technology

[0002] Oil extraction rods and fittings are indispensable core components of mechanical oil extraction systems, including sucker rods, polished rods, weighted rods, and tubing. They are primarily used to connect the surface drive unit to the downhole pump, transmitting power and forming a fluid lifting channel. Among these, the sucker rod is a key component in rod pump systems, used to connect the surface pumping unit and the downhole pump. Its core function is to transmit the reciprocating motion of the pumping unit to the pump, driving the plunger inside the pump to work, thereby drawing crude oil to the surface.

[0003] Sucker rods are used in complex outdoor environments, making surface treatment crucial. The current process involves horizontally mounting multiple sucker rods onto a horizontal mounting frame, then immersing the entire frame in a salt bath for centralized treatment. However, this process has significant drawbacks: Because of their large length-to-diameter ratio and slender shape, sucker rods have high inherent deflection. When placed horizontally in a mounting bracket, the middle of the rod sags significantly due to its own weight. Existing mounting brackets cannot provide sufficient tension to keep them straight, causing the rod to easily harden and bend after surface treatment, ultimately rendering it unusable due to excessive bending. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a surface treatment fixing bracket for oil extraction rods and pipe fittings, which enhances the tension effect on the sucker rod, thereby preventing the sucker rod from sagging and bending, and ensuring the production quality of the sucker rod.

[0005] This utility model discloses a surface treatment fixing frame for oil extraction rods and pipe fittings, comprising: a plurality of tensioning seats and positioning screws respectively provided at both ends of the support frame; the tensioning seats can be connected to the support frame through the positioning screws; a plurality of tensioning nuts are engaged between the tensioning seats, and the tensioning nuts on the tensioning seats at both ends of the support frame are aligned; the workpiece can be connected to the two aligned tensioning nuts.

[0006] Furthermore, the support frame includes a base frame, on which support columns are provided, and uprights are provided between the support columns.

[0007] Both the base frame and the upright frame are equipped with reinforcing bars.

[0008] The top and side of the support column are respectively provided with a lifting hole and a first positioning hole, and the positioning screw can be fitted into the first positioning hole.

[0009] Furthermore, the tensioning seat has a protrusion on its side, which can abut against the side of the support column; The tensioning seat has a slot, into which the tensioning nut can be engaged.

[0010] The tensioning seat is also provided with a second positioning hole, into which the positioning screw can be inserted.

[0011] Furthermore, the tensioning nut includes a neck, with a rotating part and a connecting part at each end of the neck; the neck can be fitted into a slot, and the inner side of the rotating part can abut against the outer side of the tensioning seat.

[0012] The connecting part is provided with connecting holes for connecting workpieces.

[0013] Furthermore, the connecting hole is a threaded hole.

[0014] Furthermore, the reinforcing rods form several triangular structures inside both the base frame and the upright frame.

[0015] The advantages of this utility model compared with the prior art are: The sucker rod is threadedly connected to the tension nut and is secured to the support frame and tensioning seat by the tension nut. Rotating the tension nut allows the sucker rod to be tensioned on the support frame, preventing excessive sagging. Several reinforcing rods on the support frame provide sufficient support strength for the high-strength tensioning of the sucker rods. Attached Figure Description

Detailed Implementation

[0018] like Figures 1-6 As shown, this embodiment is achieved through the following technical solution: several tension seats 2 and positioning screws 3 are respectively provided at both ends of the support frame 1. The tension seats 2 can be connected to the support frame 1 through the positioning screws 3. Several tension nuts 4 are locked between the tension seats 2. The tension nuts 4 on the tension seats 2 at both ends of the support frame 1 are aligned. The workpiece can be connected to the two aligned tension nuts 4.

[0019] In this embodiment, several tensioning seats 2 are stacked, and the slots 202 can be fastened to the tensioning nuts 4. The positions of the slots 202 on adjacent tensioning seats 2 correspond one-to-one, and two slots 202 are joined to form a mounting hole. The tensioning nut 4 is inserted into the mounting hole. Figure 2 , Figure 4 As shown; preferably, the tension nut 4 and the mounting hole are clearance fit, and the tension nut 4 can rotate in the mounting hole. Specifically, the support frame 1 includes a base frame 101, on which support columns 103 are provided, and uprights 102 are provided between the support columns 103.

[0020] Both the base frame 101 and the upright frame 102 are equipped with reinforcing rods 106.

[0021] The top and side of the support column 103 are respectively provided with a lifting hole 104 and a first positioning hole 105, and the positioning screw 3 can be fitted into the first positioning hole 105.

[0022] The positioning screw 3 can pass through the second positioning hole 203 and be threaded into the first positioning hole 105, thereby fixing the tensioning seat 2 to the support frame 1.

[0023] The lifting hole 104 can be used to connect lifting tools to facilitate the lifting of the support frame 1.

[0024] Specifically, the reinforcing rods 106 form several triangular structures inside the base frame 101 and the upright frame 102, ensuring that the support frame 1 has sufficient rigidity and stability when subjected to tension and is not easily deformed.

[0025] Specifically, the tensioning seat 2 has a protrusion 201 on its side, which can abut against the side of the support column 103.

[0026] The tensioning seat 2 is provided with a slot 202, and the tensioning nut 4 can be locked into the slot 202.

[0027] The tensioning seat 2 is also provided with a second positioning hole 203, into which the positioning screw 3 can be inserted. In this embodiment, the second positioning hole 203 is provided on the protrusion 201, such as... Figure 2 As shown. The protrusions 201 at both ends of the tensioning seat 2 can abut against one side of the support column 103, thereby achieving lateral fixation of the tensioning seat 2 on the support frame 1, as shown. Figure 1 As shown.

[0028] Specifically, the tensioning nut 4 includes a neck 402, with a rotating part 401 and a connecting part 403 at both ends of the neck 402; the neck 402 can be fitted into the slot 202, and the inner side of the rotating part 401 can abut against the outer side of the tensioning seat 2.

[0029] The connecting part 403 is provided with a connecting hole 404 for connecting workpieces. In this embodiment, the connecting part 403 is in the shape of a regular hexagonal prism.

[0030] Specifically, the connecting hole 404 is a threaded hole. The neck 402 can be inserted into the aforementioned mounting hole.

[0031] In this embodiment, the workpiece is a sucker rod 5. Conventionally, the head of the sucker rod 5 is threaded, and the head of the sucker rod 5 can be fitted into the connecting hole 404. Figure 4 As shown.

[0032] The specific working principle of this utility model is as follows: First, tension nuts 4 are installed at both ends of the sucker rod 5 to form a pre-assembled component. Next, the first layer of tension seats 2 is installed onto the support frame 1, and the tension nuts 4 at both ends of the pre-assembled component are aligned and snapped into the slots 202. The rotating part 401 abuts against one side of the tension seat 2 to achieve axial fixation of the tension nuts 4. After the pre-assembled components on the first layer of tension seats 2 are aligned and installed, the second layer of tension seats 2 is installed, and its own slots 202 are engaged with the tension nuts 4 of the pre-assembled component. The tension nuts 4 can then be snapped between the two tension seats 2. This process is repeated, with the tension seats 2 and pre-assembled components being installed layer by layer onto the support frame 1. Figure 6 As shown.

[0033] Furthermore, the tensioning nuts 4 at both ends of the pre-assembled component are manually tightened using power tools. The two ends of the sucker rod 5 move axially towards the tensioning nuts 4, causing the sucker rod 5 to be stretched and tightened, thus significantly reducing the sag in the middle of the sucker rod 5. After all the sucker rods 5 are tensioned, the support frame 1 can be transported to the salt bath for surface treatment.

[0034] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
