Description

Technical Field

[0001] This utility model relates to tooling for oil pumping units, specifically a welding tooling for supporting oil pumping units. Background Technology

[0002] Pumping unit supports play a crucial role in pumping unit installation, primarily supporting the structural weight of the pumping unit itself. Traditional pumping unit supports consist of a top plate and four legs welded to the bottom of the top plate. Welding typically involves one worker holding the legs upright while another worker welds them. This method is not only inefficient but also requires a high level of coordination between the two workers. Due to the length of the legs, it is difficult to keep the hands steady while manually holding them upright. If the legs are not properly aligned, the welded support will be defective. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a welding fixture for oil pumping unit support.

[0004] The technical solution of this utility model is: a pumping unit support welding fixture, including a top seat bracket and a pair of support leg brackets; The top support bracket includes a first base, and a first clamp is mounted on the upper end of the first base by a first column; The outrigger bracket includes a second base, and a connecting seat is mounted on the upper end of the second base through a second column. A guide slide rod that penetrates the connecting seat vertically is fixedly mounted on the connecting seat, and a shaft rod that penetrates the connecting seat vertically is rotatably mounted on the connecting seat. The upper and lower ends of the guide slide are slidably connected to an upper slide block and a lower slide block, respectively. The end of the upper slide block is connected to a second clamp, and the end of the lower slide block is connected to a third clamp. The top of the shaft is provided with a knob, the upper end of the shaft is provided with a first external thread that is threaded to the upper slide block, and the lower end of the shaft is provided with a second external thread that is threaded to the lower slide block. The helical lines of the first external thread and the second external thread are opposite.

[0005] Preferably, both the first column and the second column are lifting rod structures.

[0006] Preferably, the lifting rod structure is a hydraulic cylinder or an electric telescopic rod.

[0007] Preferably, the first base and the second base are water-filled bases.

[0008] Preferably, the first clamp, the second clamp, and the third clamp are G-shaped clamps.

[0009] Compared with the prior art, this utility model has the following advantages: This invention enables the assembly and positioning of the outriggers and the top mount, thereby facilitating welding, improving work efficiency, and effectively increasing the yield rate. In addition, the top mount bracket and the outrigger bracket adopt a split structure, and the distance between the second clamp and the third clamp can be adjusted simultaneously by a knob, thus adapting to the assembly and welding of outriggers with different design angles, making this invention more flexible and convenient to use.

[0010] Rotating the knob drives the shaft to rotate, and the reverse-designed threads at both ends of the shaft drive the upper slide and the lower slide to move synchronously. This enables the second and third clamps to move synchronously relative to each other or synchronously in opposite directions, thereby adjusting the distance between the second and third clamps to accommodate different angles of the support legs and improving the flexibility of this invention.

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0013] like Figures 1 to 4 A welding fixture for supporting an oil pumping unit includes a top support bracket 1 and a pair of symmetrically arranged support leg brackets 2.

[0014] The top support bracket 1 includes a first base 6, a first column 7 and a first clamp 8. The upper end of the first base 6 is connected to the bottom of the first column 7, and the top of the first column 7 supports and installs the first clamp 8.

[0015] The outrigger bracket 2 mainly includes a second base 9, a second column 10 is installed on the upper end of the second base 9, a connecting seat 11 is supported on the top of the second column 10, a guide slide rod 17 that runs vertically through the connecting seat 11 is fixedly installed on the connecting seat 11, and a shaft rod 12 that runs vertically through the connecting seat 11 is also rotatably installed on the connecting seat 11.

[0016] The upper and lower ends of the guide slide rod 17 are slidably connected to the upper slide block 15 and the lower slide block 19, respectively. The end of the upper slide block 15 is connected to the second clamp 16, and the end of the lower slide block 19 is connected to the third clamp 18. The first clamp 8, the second clamp 16, and the third clamp 18 can be G-shaped clamps.

[0017] The top of the shaft 12 is provided with a knob 13, the upper end of the shaft 12 is provided with a first external thread 14 that is threaded to the upper slide 15, and the lower end of the shaft 12 is provided with a second external thread 20 that is threaded to the lower slide 19. The spiral lines of the first external thread 14 and the second external thread 20 are opposite.

[0018] Rotating the knob 13 drives the shaft 12 to rotate. Under the action of the threads designed in opposite directions at both ends of the shaft 12, the upper slide 15 and the lower slide 19 are driven to move synchronously, thereby enabling the second clamp 16 and the third clamp 18 to move synchronously relative to each other or synchronously in opposite directions, thus realizing the adjustment of the distance between the second clamp 16 and the third clamp 18.

[0019] Working principle: The pumping unit support 3 mentioned in this utility model consists of a top seat 5 and four legs 4. At the bottom of the top seat 5, there are four plugs 21 pre-welded according to the design angle. The legs 4 adopt a tubular structure that is compatible with the plugs 21.

[0020] When in use, first arrange the top bracket 1 and a pair of leg brackets 2 in a triangular arrangement, then fix the top bracket 5 with the first clamp 8, and then adjust the distance between the two leg brackets 2 according to the design installation angle of the leg 4 and the top bracket 5, as well as adjust the height of the second clamp 16 and the third clamp 18 on the leg bracket 2. Then, the front end of each support leg 4 is inserted into the pre-welded connector on the top seat 5, and the end of the support leg 4 is mounted on the corresponding clamp. The four support legs 4 are arranged as follows. Figure 1 After the arrangement shown is completed, welding will be performed.

[0021] This utility model enables the assembly and positioning of the support legs 4 and the top seat 5 through the top seat bracket 1 and a pair of support leg brackets 2, thereby facilitating welding, improving work efficiency, and effectively increasing the yield rate. In addition, the top seat bracket 1 and the support leg brackets 2 adopt a split structure, and the distance between the second clamp 16 and the third clamp 18 can be adjusted simultaneously by the knob 13, which can adapt to the assembly and welding of support legs 4 at different angles, making this utility model more flexible and convenient to use. Example 2

[0022] This embodiment is a further optimization based on the above embodiment, specifically: like Figures 1 to 3Both the first column 7 and the second column 10 are lifting rod structures, which can be hydraulic cylinders or electric telescopic rods.

[0023] In addition, the first base 6 and the second base 9 are water-filled bases. By adding water, they achieve counterweight, making them more stable to use. When storing, draining the water makes them easier to move.

[0024] 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.
