Description

Technical Field

[0001] This utility model relates to the field of oil drilling and production equipment manufacturing technology, specifically to a shaft support device for an oil pumping unit. Background Technology

[0002] The manufacturing quality of the pumping unit bearing assembly directly affects the smooth installation of intermediate bearing housings, walking beams, donkey heads, connecting rod assemblies, and boom assemblies, as well as the normal operation of the pumping unit after installation. To ensure the manufacturing and installation accuracy of the pumping unit, the manufacturing quality of the pumping unit bearing assembly must be guaranteed. The pumping unit bearing assembly manufacturing equipment is an indispensable process equipment for ensuring the manufacturing quality of the pumping unit.

[0003] The structure of the pumping unit shaft seat assembly consists of two shaft seats welded onto a hollow base plate. The center distance between the two shaft seats is relatively large, requiring a high degree of flatness of the base plate after welding. Due to varying degrees of welding deformation during the welding process, the flatness of the base plate of the pumping unit shaft seat assembly cannot be guaranteed. To meet this requirement, without adopting new process equipment, it is necessary to leave machining allowance for the base plate thickness before welding and to machine the bottom surface of the base plate after welding, finally drilling the connecting bolt holes on the bottom surface. This method not only increases the cost of raw materials and machining but also makes it difficult to ensure on-time product delivery.

[0004] Therefore, in order to reduce manufacturing costs and shorten the manufacturing cycle while ensuring product quality, there is an urgent need for a new type of pumping unit shaft assembly manufacturing device. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: a shaft seat device for an oil pumping unit, comprising a shaft seat body and a base plate, and further comprising a welding component for facilitating welding by laying the base plate flat. The base plate is fixedly installed on the top side of the welding component by fasteners. The shaft seat body is symmetrically and vertically erected on the top side of the base plate. The shaft seat body is fixedly welded to the top side of the base plate, and the center of the base plate has a hollow groove.

[0006] As an optimization, the welded component includes a lower panel and an upper panel, with the upper panel located above the lower panel. A stiffening plate is fixedly welded between the lower panel and the upper panel, and the stiffening plate is symmetrically arranged. Two sets of symmetrical stiffening plates are fixedly welded between the two stiffening plates, and the stiffening plates are welded between the lower panel and the upper panel. A hollow portion is provided in the middle of both the lower panel and the upper panel.

[0007] As an optimization, the upper panel is provided with bolt holes with internal threads at the corresponding hole positions of the base plate, and the fasteners are located in the bolt holes to fix the base plate.

[0008] As an optimization, the fastener includes a bolt screwed into a bolt hole, a nut being helically fitted at the bottom of the bolt, and a rubber washer being placed between the top of the bolt and the base plate.

[0009] As an optimization, a number of threaded holes are provided on the outer side of the lower panel, and a drilling positioning component is provided in the threaded holes.

[0010] As an optimization, the drilling positioning assembly includes a screw screwed into a threaded hole, a stop plate sleeved on the outer side of the screw, an internal hexagonal portion opened at the center of the head of the screw, and a buffer component provided between the head of the screw and the stop plate.

[0011] As an optimization, the buffer includes a washer sleeved on the outside of the screw, and the washer abuts against one side of the abutment plate. A rotating ring is rotatably connected inside the head of the screw, and a spring is fixedly installed between the rotating ring and the washer.

[0012] The beneficial effects of this utility model are:

[0013] 1. The shaft seat device for the pumping unit is manufactured by welding and correcting the deformed welded parts, so that the machined upper panel meets the flatness requirements of the bottom surface of the base plate in the shaft seat assembly drawing. Bolt holes are drilled on the machined upper panel to connect with the base plate of the shaft seat assembly, which are used to connect the base plate and the upper panel before welding the pumping unit shaft seat assembly. This can effectively control the problem that the flatness of the bottom surface of the pumping unit shaft seat assembly cannot be guaranteed after welding due to welding deformation caused by welding the shaft seat on the upper panel during the manufacturing process of the pumping unit shaft seat assembly.

[0014] 2. The shaft seat device for the oil pumping unit, by inserting the hexagonal rod into the internal hexagonal part and turning it, can drive the screw to rotate into the threaded hole. Therefore, the spring is compressed through the rotating ring, and the washer is pressed tightly against the abutment plate. This pushes the abutment plate against the outside of the top plate, thereby positioning the base plate placed on the top plate. Since there are drilling positioning components on all four sides, the position of the drilled bolt holes can be accurately positioned, improving accuracy.

[0015] 3. Compared with the prior art, the shaft seat device for oil pumping units has a simple structure, is easy to manufacture, has low cost, and is economical and practical. While ensuring product quality, it reduces the raw material cost and machining cost of oil pumping unit shaft seat assembly, shortens the manufacturing cycle, greatly improves the economic benefits of oil pumping unit manufacturing, and provides valuable experience for the manufacturing of similar products in the future.

[0022] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 A shaft seat device for an oil pumping unit includes a shaft seat body 1 and a base plate 2, and also includes a welding component for facilitating welding by laying the base plate 2 flat. The base plate 2 is fixedly installed on the top side of the welding component by fasteners. The shaft seat body 1 is symmetrically and vertically erected on the top side of the base plate 2. The shaft seat body 1 is fixedly welded to the top side of the base plate 2, and the center of the base plate 2 has a hollow groove.

[0025] Please see Figures 1-3The welded parts include a lower panel 3 and an upper panel 4, with the upper panel 4 located above the lower panel 3. The upper panel 4 has bolt holes with internal threads at the positions corresponding to the holes in the base plate 2. Fasteners are located in the bolt holes to fix the base plate 2. A stiffener 5 is fixedly welded between the lower panel 3 and the upper panel 4, and the stiffener 5 is symmetrically arranged. Two sets of symmetrical stiffeners 6 are fixedly welded between the two stiffeners 5, and the stiffeners 6 are welded between the lower panel 3 and the upper panel 4. A hollow part 7 is provided in the middle of both the lower panel 3 and the upper panel 4.

[0026] Please see Figures 1-3 The fasteners include bolts 8 screwed into bolt holes, with nuts 9 spirally fitted at the bottom of bolts 8, and rubber washers between the top of bolts 8 and the base plate 2. By inserting bolts 8 into the holes of the base plate 2 and screwing them into the bolt holes of the upper panel 4, the base plate 2 can be positioned. Then, the nuts 9 are tightened at the bottom of bolts 8 for further installation and fixation.

[0027] Please see Figures 4-5 The lower panel 3 has several threaded holes on its outer side. A drilling positioning component is installed in the threaded hole. The drilling positioning component includes a screw 10 screwed into the threaded hole. A backing plate 11 is sleeved on the outer side of the screw 10. An internal hexagonal part 12 is opened at the center of the head of the screw 10. A buffer is provided between the head of the screw 10 and the backing plate 11. By inserting the hexagonal rod into the internal hexagonal part 12 and turning it, the screw 10 can be rotated into the threaded hole. Then, the buffer will push the backing plate 11 to stick to the outer side of the upper panel 4, thereby positioning the bottom plate 2 placed on the upper panel 4. Since the drilling positioning component is provided on all four sides, the position of the drilled bolt hole can be accurately positioned, improving accuracy.

[0028] Please see Figures 4-5 The buffer includes a washer 13 sleeved on the outside of the screw 10, and the washer 13 abuts against one side of the abutment plate 11. A rotating ring 14 is rotatably connected inside the head of the screw 10. A spring 15 is fixedly installed between the rotating ring 14 and the washer 13. When the screw 10 is screwed into the threaded hole, the rotating ring 14 will compress the spring 15 and make the washer 13 fit tightly against the abutment plate 11, thereby playing a buffering role and preventing it from being tightened too much and getting stuck.

[0029] In use, firstly, assemble and weld the lower panel 3, upper panel 4, stiffener 1 5, and stiffener 2 6 together. Then, process the surface of the upper panel 4 according to the flatness requirements of the bottom surface of the pumping unit shaft seat assembly. Next, drill the connecting bolt holes on the upper panel 4 according to the hole size and position of the bottom plate 2 of the pumping unit shaft seat assembly. Then, insert the bolt 8 into the hole of the bottom plate 2 and screw it into the bolt hole of the upper panel 4 to fix the bottom plate 2 in place. Then, tighten the nut 9 on the bottom of the bolt 8 for further installation and fixation. Thus, the bottom plate 2 can be fixed to the top side of the upper panel 4. Then, stand the shaft seat body 1 on the top side of the bottom plate 2 for welding. After the workpiece has completely cooled, remove the bolt 8 connecting the bottom plate 2 and the upper panel 4.

[0030] Meanwhile, when drilling bolt holes on the top plate 4 that correspond to the holes in the bottom plate 2, inserting the hexagonal rod into the internal hexagonal part 12 and turning it will drive the screw 10 to rotate into the threaded hole. Therefore, the spring 15 will be compressed through the rotating ring 14, and the washer 13 will be pressed tightly against the abutment plate 11. This will push the abutment plate 11 to the outside of the top plate 4, thereby positioning the bottom plate 2 placed on the top plate 4.

[0031] In summary, the shaft seat device for the pumping unit, through welding and correction of the deformed welded parts, ensures that the machined upper panel 4 meets the required flatness of the bottom surface of the base plate 2 in the shaft seat assembly drawing. Bolt holes are drilled on the machined upper panel 4 to connect with the base plate 2 of the shaft seat assembly for connection between the base plate 2 and the upper panel 4 before welding of the pumping unit shaft seat assembly. This effectively controls the problem of welding deformation caused by welding the shaft seat on the upper plate 4 during the manufacturing process of the pumping unit shaft seat assembly, which leads to the inability to guarantee the flatness of the bottom surface of the pumping unit shaft seat assembly after welding.

[0032] By inserting the hexagonal rod into the internal hexagonal part 12 and turning it, the screw 10 can be rotated into the threaded hole. This will compress the spring 15 through the rotating ring 14 and make the washer 13 press tightly against the abutment plate 11. This will push the abutment plate 11 against the outside of the top plate 4, thereby positioning the base plate 2 placed on the top plate 4. Since drilling positioning components are provided on all four sides, the position of the drilled bolt hole can be accurately positioned, improving accuracy.

[0033] Compared with existing technologies, this utility model has a simple structure, is easy to manufacture, has low cost, and is economical and practical. While ensuring product quality, it reduces the raw material cost and machining cost of the pumping unit shaft assembly, shortens the manufacturing cycle, greatly improves the economic benefits of pumping unit manufacturing, and provides valuable experience for the manufacturing of similar products in the future.
