Technical Field
[0001] This application relates to the field of hoisting technology, and in particular to a hoisting structure for a drilling pump frame and pump set. Background Technology
[0002] Currently, drilling pump frames and pump sets are the core power equipment in oil drilling. Their main function is to provide high-pressure power for the drilling fluid circulation system, drive the mud through the drill string to clean the bottom of the well, carry cuttings, and balance formation pressure. Drilling pump frames and pump sets are usually composed of a frame, pump head, motor, transmission system, etc. They have significant characteristics of "heavy load" and "large size" and require extremely high installation precision. Therefore, a hoisting structure is needed to move and install the drilling pump frames and pump sets. Currently, double cranes and hoisting structures are usually used to hoist the drilling pump frames and pump sets.
[0003] The existing technical solutions mentioned above have the following drawbacks: during the hoisting process, the lifting and luffing synchronization of the two cranes needs to be coordinated, which takes a long time to debug and is inefficient. Utility Model Content
[0004] This application provides a hoisting structure for drilling pump frames and pump sets to improve the hoisting efficiency of drilling pump frames and pump sets.
[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:
[0006] A drilling pump frame and pump assembly hoisting structure includes a horizontally arranged hoisting beam. Sliding holes are provided on both sides of the hoisting beam, which are spaced apart from the upper side wall, connecting the inside and outside of the hoisting beam. Two connecting rods are slidably arranged at intervals within the sliding holes. The length direction of the connecting rods is perpendicular to the length direction of the hoisting beam. The two connecting rods can move synchronously towards or away from each other. Connecting components are connected to the lower side walls of the connecting rods via connecting columns. A rectangular hoisting frame is provided between the two connecting rods. The hoisting frame is fitted onto the outer wall of the hoisting beam, and a circular hoisting ring is fixed to the upper outer wall of the hoisting frame.
[0007] By adopting the above technical solution, and by setting up a lifting beam, connecting rods, connecting components, lifting frame, and lifting ring, the two connecting rods can adjust their spacing through synchronous movement to adapt to drilling pump frames and pump sets of different sizes. At the same time, the lifting frame and lifting ring facilitate connection with the crane, thereby improving the adaptability of the lifting structure to different equipment. The lifting beam, lifting frame, and lifting ring can be used with a single crane, which reduces the commissioning time and improves the lifting efficiency compared to lifting with two cranes.
[0008] Optionally, the connecting assembly includes a hoisting square tube closed at both ends. The upper outer wall of the hoisting square tube is connected to the connecting rod at both ends via connecting columns. The lower side wall of the hoisting square tube has a sliding groove that connects the inside and outside of the hoisting square tube. Two hoisting components are slidably arranged inside the hoisting square tube and in the sliding groove. The two hoisting components are spaced apart and can move synchronously. One end of the hoisting component is located inside the hoisting square tube, and the other end of the hoisting component is located outside the hoisting square tube. A circular hoisting structural component is fixedly connected to the end face of the hoisting component away from the connecting rod.
[0009] By adopting the above technical solution, and by setting up a hoisting square tube and hoisting components, the hoisting components can move synchronously within the sliding groove. This allows the position of the hoisting components within the hoisting square tube and the spacing between the two hoisting components to be adjusted according to the hoisting point positions of the drilling pump frame and pump set. This facilitates connection with the drilling pump frame and pump set and enhances the flexibility of the hoisting structure.
[0010] Optionally, two racks are slidably arranged inside the hoisting beam, with the racks spaced apart and their teeth facing each other. The ends of the racks that are far apart from each other are fixedly connected to the side walls of the two connecting rods. A synchronous gear is rotatably arranged on the upper inner wall of the hoisting beam, and the synchronous gear meshes with both racks. A drive motor is arranged on the upper outer wall of the hoisting beam, with the output shaft of the drive motor pointing vertically downward and the end of the output shaft passing through the hoisting beam and being coaxially fixedly connected with the synchronous gear. The drive motor is spaced apart from the inner wall of the hoisting frame.
[0011] By adopting the above technical solution, and by setting up a rack, a synchronous gear and a drive motor, the drive motor can drive the synchronous gear to rotate, so that the two racks can synchronously drive the connecting rods to move closer or further apart, thereby realizing the automatic adjustment of the distance between the connecting rods. This eliminates the need for manual operation, reduces debugging steps, and improves hoisting efficiency.
[0012] Optionally, the outer wall of the hoisting beam is fixedly connected to the inner wall of the hoisting frame, the hoisting beam is located at the lower end inside the hoisting frame, the hoisting frame is located at the synchronous gear, and the surfaces of the two racks that are opposite to each other are slidably attached to the surfaces of the inner wall of the hoisting frame.
[0013] By adopting the above technical solution, and by setting the rack surface to slide against the inner wall of the hoisting frame, the hoisting frame can limit the movement trajectory of the rack, reduce the possibility of the connecting rod tilting during the sliding process, make the movement of the connecting rod more stable, and thus ensure the reliability of the hoisting structure during the adjustment process.
[0014] Optionally, a lead screw is rotatably installed inside the hoisting square tube. The two ends of the lead screw are respectively rotatably embedded in the two end walls of the hoisting square tube, and one end of the lead screw protrudes from the hoisting square tube and is located outside the hoisting square tube. The peripheral wall of the lead screw is provided with two sections of thread, the two ends of which have opposite directions of rotation and are connected to each other. The hoisting components are sleeved on the peripheral wall of the lead screw, and the two hoisting components respectively engage with the two sections of thread on the peripheral wall of the lead screw.
[0015] By adopting the above technical solution, and by setting a lead screw with two sections of threads in opposite directions on the peripheral wall of the lead screw, the two lifting parts can be engaged with the two sections of threads respectively. When the lead screw is rotated, the two lifting parts can move synchronously closer or further apart from each other, thereby adjusting the distance between the two lifting parts. This makes it easier to adapt to different spacings of lifting points on the drilling pump frame and pump set, and improves the convenience of connection.
[0016] Optionally, the two opposite side walls of the hoisting component are provided with limiting grooves that are adapted to the hoisting square cylinder walls on both sides of the sliding groove, and the limiting grooves are slidably sleeved on the hoisting square cylinder walls on both sides of the sliding groove.
[0017] By adopting the above technical solution, and by setting limiting grooves on both sides of the lifting component, and by sliding the limiting grooves onto the walls of the lifting square tube on both sides of the sliding groove, the movement trajectory of the lifting component can be restricted, preventing the lifting component from separating from the lifting square tube during movement, while reducing the possibility of the lifting component swaying, keeping the lifting component stable during the lifting process, and ensuring the reliability of the connection.
[0018] Optionally, a strip-shaped rotating plate is fixedly connected to the end of the lead screw located outside the hoisting square tube. One end of the rotating plate is fixedly connected to the end face of the lead screw. An operating column is rotatably mounted on the rotating plate away from the lead screw. The operating column is away from the lead screw, and its end is rotatably embedded in the rotating plate.
[0019] By adopting the above technical solution, and by setting up a rotating plate and an operating column, the rotating plate and lead screw can be rotated by manually rotating the operating column, thereby adjusting the position of the hoisting component. No additional power equipment is required, which makes it convenient to quickly adjust the position of the hoisting point on site according to actual needs and improves the ease of operation.
[0020] Optionally, the drive motor is a stepper motor.
[0021] By adopting the above technical solution, the stepper motor, with its excellent control performance, can precisely adjust the rotation angle of the synchronous gear, thereby accurately controlling the movement distance of the rack and connecting rod. This makes the spacing adjustment of the connecting rod more precise, ensuring the accurate connection position between the hoisting structure and the drilling pump frame and pump set, and improving the accuracy and efficiency of hoisting.
[0022] In summary, this application has the following technical effects:
[0023] 1. By setting up lifting beams, connecting rods, connecting components, lifting frames, and lifting rings, the two connecting rods can adjust their spacing through synchronous movement to adapt to drilling pump frames and pump sets of different sizes. At the same time, the lifting frame and lifting ring facilitate connection with the crane, thereby improving the adaptability of the lifting structure to different equipment. Lifting can be carried out using a single crane through the lifting beams, lifting frames, and lifting rings, which reduces commissioning time and improves lifting efficiency compared to lifting with two cranes.
[0024] 2. By setting up a lifting square tube and lifting components, the lifting components can move synchronously in the sliding groove. This allows the position of the lifting components in the lifting square tube and the spacing between the two lifting components to be adjusted according to the lifting point position of the drilling pump frame and pump set. This facilitates connection with the drilling pump frame and pump set and enhances the flexibility of the lifting structure.
[0025] 3. By incorporating a rack, a synchronous gear, and a drive motor, the drive motor can rotate the synchronous gear, causing the two racks to move the connecting rods closer or further apart, thus achieving automatic adjustment of the connecting rod spacing. This eliminates the need for manual operation, reduces debugging steps, and improves hoisting efficiency. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.
[0030] This application discloses a drilling pump frame and pump set hoisting structure, referring to... Figure 1 The hoisting structure includes a hoisting component 1 and a connecting component 2. The hoisting component 1 is connected to the drilling pump frame and pump set through the connecting component 2. The hoisting component 1 can be hoisted by a single crane, which improves hoisting efficiency compared to hoisting by a double crane.
[0031] Combination Figure 1 and Figure 2The hoisting assembly 1 includes a horizontally arranged hoisting beam 11, which is a square tube closed at both ends. Sliding holes 111 are provided on both side walls adjacent to the upper side wall of the hoisting beam 11. The sliding holes 111 connect the inside and outside of the hoisting beam 11, and the length direction of the sliding holes 111 is parallel to the length direction of the hoisting beam 11. The side walls of the sliding holes 111 are flush with the upper and lower inner walls of the hoisting beam 11, respectively. Two connecting rods 12 are slidably arranged at intervals within the sliding holes 111 on both side walls of the hoisting beam 11. The connecting rods 12 are square rods, and their length direction is perpendicular to the length direction of the hoisting beam 11. The opposite side walls of the connecting rods 12 are slidably fitted against the side walls of the sliding holes 111. The hoisting beam 11 is located at the midpoint of the length of the connecting rods 12.
[0032] Combination Figure 1 and Figure 2 The hoisting beam 11 contains two racks 13, spaced apart with their teeth facing each other. The length of the racks 13 is parallel to the length of the hoisting beam 11. The ends of the racks 13 that are far apart are fixed to the opposite sidewalls of the two connecting rods 12. A synchronizing gear 14 is rotatably mounted on the upper sidewall of the hoisting beam 11. The axis of the synchronizing gear 14 is perpendicular to the upper sidewall of the hoisting beam 11. The synchronizing gear 14 meshes with both racks 13. The synchronizing gear 14 is located in the middle of the hoisting beam 11, and the two racks 13 are located on either side of the synchronizing gear 14. The rotation of the synchronizing gear 14 drives the two connecting rods 12 to move synchronously, moving closer to or further away from each other, via the two racks 13. A drive motor 15 is installed on the upper outer wall of the hoisting beam 11. The output shaft of the drive motor 15 is vertically downward. The end of the output shaft of the drive motor 15 passes through the upper wall of the hoisting beam 11 and is coaxially fixed to the synchronous gear 14. The drive motor 15 drives the synchronous gear 14 to rotate. The drive motor 15 is a stepper motor.
[0033] Combination Figure 1 and Figure 2 Each connecting rod 12 has two rollers (not shown in the figure) rotatably embedded in the side wall away from the drive motor 15. The two rollers are spaced apart and are located in two sliding holes 111 on both sides of the hoisting beam 11. The peripheral wall of the roller is in contact with the hole wall of the sliding hole 111, and the roller axis is parallel to the length direction of the connecting rod 12. The rollers can reduce the friction between the connecting rod 12 and the inner wall of the hoisting beam 11 and the wall of the sliding hole 111, thereby improving the service life of the hoisting structure.
[0034] Combination Figure 1 and Figure 2A lifting frame 16 is fitted along the middle of the lifting beam 11. The lifting frame 16 is a rectangular frame composed of four square rods, vertically positioned between two connecting rods 12. The lower outer wall of the lifting beam 11 and the two adjacent outer walls are respectively in contact with the lower end face and opposite surfaces of the inner wall of the lifting frame 16. The inner wall of the lifting frame 16 is spaced apart from the drive motor 15. A circular lifting ring 17 is fixed to the upper end face of the outer wall of the lifting frame 16 for easy connection with the crane, facilitating the lifting of the drilling pump frame and pump assembly. The opposing surfaces of the two racks 13 slide in contact with the opposing surfaces of the inner wall of the lifting frame 16, thereby cooperating with the synchronous gear 14 to limit the movement trajectory of the racks 13 and reduce the possibility of the connecting rods 12 tilting during sliding.
[0035] Combination Figure 1 and Figure 2 The connecting assembly 2 includes two horizontally arranged lifting square tubes 21, each with closed ends. The length direction of the lifting square tubes 21 is parallel to the direction of the connecting rod 12. The upper outer walls of the two lifting square tubes 21 are connected to the lower outer walls of the two connecting rods 12 via connecting columns. The lifting square tubes 21 can move with the connecting rods 12. A sliding groove 211 is provided on the side wall of the lifting square tubes 21 away from the connecting rods 12. The sliding groove 211 connects the inside and outside of the lifting square hole, and the length direction of the sliding groove 211 is parallel to the length direction of the lifting square tubes 21.
[0036] Combination Figure 1 and Figure 2 Two lifting components 22 are slidably installed inside each lifting square tube 21 and in the sliding groove 211. The lifting components 22 are square columns, and the two lifting components 22 are vertical and spaced apart. One end of the lifting component 22 is located inside the lifting square tube 21, and the other end of the lifting component 22 is located outside the lifting square tube 21. A lead screw 23 is rotatably installed inside the hoisting square tube 21. The axis of the lead screw 23 is parallel to the length direction of the hoisting square tube 21. Both ends of the lead screw 23 are rotatably embedded in the end walls of the hoisting square tube 21, and one end of the lead screw 23 protrudes from the hoisting square tube 21 and is located outside the hoisting square tube 21. The peripheral wall of the lead screw 23 is spaced apart from the inner wall of the hoisting square tube 21. The peripheral wall of the lead screw 23 has two threads along its axial direction. The two threads have opposite directions and their adjacent ends are connected to each other. The hoisting components 22 located inside the hoisting square tube 21 are sleeved on the peripheral wall of the lead screw 23, and the two hoisting components 22 respectively engage with the two threads on the peripheral wall of the lead screw 23. The rotation of the lead screw 23 can drive the two hoisting components 22 to move synchronously, moving closer or further away from each other.
[0037] Combination Figure 1 and Figure 2The two opposite sides of the lifting component 22 are provided with limiting grooves 221 that are adapted to the walls of the lifting square tubes 21 on both sides of the sliding groove 211. The walls of the lifting square tubes 21 on both sides of the sliding groove 211 are slidably disposed in the limiting grooves 221. The limiting grooves 221 can restrict the movement trajectory of the lifting component 22 and reduce the possibility of the lifting component 22 separating from the lifting square tube 21. The lead screw 23 drives the two lifting components 22 to move synchronously, which facilitates the adjustment of the position of the lifting point.
[0038] Combination Figure 1 and Figure 2 The end face of the lifting component 22 facing away from the connecting rod 12 is provided with a circular lifting structure 222. The outer peripheral wall of the lifting structure 222 is fixed to the end face of the lifting component 22, and the axis of the lifting structure 222 is parallel to the length direction of the connecting rod 12. The lifting structure 222 is convenient to be connected to the drilling pump frame and pump set.
[0039] Combination Figure 1 and Figure 2 A strip-shaped rotating plate 24 is fixedly connected to the end face of the lead screw 23 protruding from the lifting square tube 21. The plate surface of the rotating plate 24 is perpendicular to the axis of the lead screw 23. One end of the plate surface of the rotating plate 24 is fixedly connected to the end face of the lead screw 23. An operating column 25 is rotatably set on the rotating plate 24 away from the plate surface of the lead screw 23. The operating column 25 is cylindrical and is far away from the lead screw 23. The axis of the operating column 25 is perpendicular to the plate surface of the rotating plate 24. One end of the operating column 25 is rotatably embedded in the rotating plate 24. The operating column 25 and the rotating plate 24 are used to rotate the lead screw 23, thereby adjusting the position of the two lifting components 22 in a lifting square tube 21 to adapt to the lifting of the drilling pump frame and pump set.
