Description

Technical Field

[0001] The invention belongs to the technical field of mud pumps and relates to a highly wear-resistant mud pump capable of modular splicing and a use method thereof. Background Art

[0002] A mud pump is a machine that delivers mud or water and other flushing fluids to the borehole during the drilling process. The mud pump is an important part of drilling machinery and equipment. Its main function is to inject mud into the well as the drill bit during the drilling process, playing the role of cooling the drill bit, cleaning the drill tool, fixing the well wall, driving the drilling, and bringing the cuttings back to the ground after drilling. In the commonly used positive circulation drilling, the mud pump sends the surface flushing medium-clean water, mud or polymer flushing fluid under a certain pressure through a high-pressure hose, a faucet and the center hole of the drill pipe column directly to the bottom of the drill bit to achieve the purpose of cooling the drill bit, removing the cut cuttings and transporting them to the surface. Commonly used mud pumps are piston or plunger type. The crankshaft of the pump is driven by the power machine to rotate, and the crankshaft drives the piston or plunger to reciprocate in the pump cylinder through the crosshead. Under the alternating action of the suction and discharge valves, the purpose of transportation is achieved.

[0003] At present, single-cylinder mud pumps and multi-cylinder mud pumps are common on the market. In order to improve the efficiency and sustainability of mud delivery, double-cylinder mud pumps and triple-cylinder mud pumps are commonly used. However, most of the current mud pumps are sold in complete sets, from the power mechanism to the cylinder body, and then to the pipeline. They are generally directly assembled into finished products before leaving the factory and cannot be modularly spliced. They have the following defects: 1. Since the volume of the entire pump body is fixed, the user cannot flexibly adjust and install it according to different scenarios, resulting in poor installation flexibility; 2. It is not easy to disassemble the power mechanism, cylinder body and pipeline, resulting in the need to move the entire pump body when a certain part needs to be repaired or replaced; 3. Since the entire pump body is not easy to disassemble, it is more laborious during transportation and has poor portability; Therefore, we propose a highly wear-resistant mud pump and a method of use that can be modularly spliced ​​to solve the above-mentioned problems.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1-Figure 4As shown, a highly wear-resistant mud pump that can be modularly spliced ​​includes two mounting seats 1, multiple connecting plates 2, two mounting blocks 3, a delivery pipe 5, a feed pipe 8, two groups of delivery mechanisms and a discharge pipe 14. The two mounting seats 1 are symmetrically arranged, and the two mounting seats 1 are fixedly connected by multiple connecting plates 2. The two mounting blocks 3 are symmetrically fixedly connected to one side of the top of the mounting seats 1, and the delivery pipe 5 is fixedly connected between the two mounting blocks 3. One end of the delivery pipe 5 passes through one side of the corresponding mounting block 3 and is fixedly connected with the feed pipe 8 for pumping in mud. The two groups of delivery mechanisms are symmetrically arranged on the top outer wall of the delivery pipe 5, and the two groups of delivery mechanisms are connected for conveying mud. The discharge pipe 14 is connected to one group of the delivery mechanisms for pumping out mud.

[0042] In one aspect of this embodiment, Figure 1-Figure 4 As shown, the feeding mechanism includes a feed guide pipe 7 which passes through and is fixedly connected to the top outer wall of the feed pipe 5, a one-way feed valve 9 is provided in the feed guide pipe 7, a hollow column 10 is fixedly connected to the top of the feed guide pipe 7, a one-way discharge valve 13 is provided in the hollow column 10, the two hollow columns 10 are connected by a through pipe 12, a discharge pipe 14 is fixedly connected to one side of one of the hollow columns 10, and the through pipe 12 and the discharge pipe 14 are both located above the one-way discharge valve 13. The mud is sucked from the feed pipe 8, enters the conveying pipe 5, then enters the hollow column 10 from the guide pipe 7, and finally flows out from the discharge pipe 14 to complete the transportation of the mud, while the mud in the two hollow columns 10 is circulated and transported through the through pipe 12; through the setting of the one-way feed valve 9 and the one-way discharge valve 13, when the piston mechanism is working, the mud can only enter the hollow column 10 from the guide pipe 7, and then enter the discharge pipe 14 from the hollow column 10, thereby realizing the one-way transportation of the mud.

[0043] like Figure 1-Figure 4 As shown, the mud pump also includes two groups of piston mechanisms connected to the two groups of feeding mechanisms respectively, which are used to transport mud. The piston mechanism includes a piston tube 15 fixedly connected to the bottom of one side of the hollow column 10, and the piston tube 15 is located below the one-way discharge valve 13. A piston rod 20 is arranged in the piston tube 15. One end of the piston rod 20 is fixedly connected to a piston 21 that is sealed and slidable with the inner wall of the piston tube 15. The other end of the piston rod 20 extends to the outside of the piston tube 15 and is connected to the driving mechanism. The driving mechanism can simultaneously drive the two piston rods 20 to move relative to each other, that is, one extends inward and moves, and the other extends outward, thereby driving the two pistons 21 to move relative to each other. When the piston 21 moves outward, the mud can be sucked from the feeding pipe 5 through the guide pipe 7 into the hollow column 10. Then, when the piston 21 moves inward, the mud in the hollow column 10 can be sent to the discharge pipe 14 through the through pipe 12 or directly, so as to realize the transportation of the mud.

[0044] In one aspect of this embodiment, Figure 1-Figure 5 As shown, the outer wall of the piston tube 15 is fixedly sleeved with a collar 24, the bottom of the collar 24 is fixedly connected with a vertical rod 23, and the bottom end of the vertical rod 23 is fixedly connected to the top of the corresponding connecting plate 2. By providing the collar 24, the installation of the piston tube 15 can be stabilized and strengthened, and the stability of the movement of the piston 21 can be effectively improved.

[0045] The present application can be used in the field of highly wear-resistant mud pumps that can be modularly spliced, and can also be applied to other fields of the present application.

[0046] Example 2

[0047] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 8 As shown, a highly wear-resistant mud pump that can be modularly spliced ​​is used in the field of mud pumps, and also includes a base plate 4 used in conjunction with a mounting seat 1. The top of the base plate 4 is provided with a driving mechanism for simultaneously driving two groups of piston mechanisms to work alternately. The driving mechanism includes a driving motor 36 fixedly connected to the top of the base plate 4, and an incomplete gear 37 is fixedly sleeved on the output shaft of the driving motor 36. The top of the base plate 4 is fixedly connected with a protective cover 16, and the protective cover 16 covers the driving motor 36. The top inner wall of the protective cover 16 is slidably connected with a rectangular frame 34, and the inner walls of the rectangular frame 34 on one side away from each other are fixedly connected with a first rack 35, and the two first racks 35 are intermittently meshed with the incomplete gear 37 respectively, and the rectangular frame 34 is connected to one of the piston rods 20. Start the driving motor 36 to drive the incomplete gear 37 to rotate, and through the intermittent meshing movement with the two first racks 35, the rectangular frame 34 can be driven to slide back and forth, and then one of the piston rods 20 can be driven to move back and forth to realize the transportation of mud.

[0048] In one aspect of this embodiment, Figure 1-Figure 8 As shown, the driving mechanism also includes a sliding block 39 slidably connected to the inner wall of the top of the protective cover 16, and the sliding block 39 is connected to another piston rod 20, the sliding block 39 is fixedly connected to the third rack 40 on one side of the rectangular frame 34, and the outer wall of the rectangular frame 34 is fixedly connected to the second rack 38 on one side of the sliding block 39, and the inner wall of the top of the protective cover 16 is rotatably connected to a rotating rod 41, and the outer wall of the rotating rod 41 is fixedly sleeved with a transmission gear 42 that meshes with the second rack 38 and the third rack 40 at the same time. When the rectangular frame 34 moves back and forth, the transmission gear 42 can be driven to rotate by the second rack 38, and the sliding block 39 is driven to move back and forth by the meshing movement with the third rack 40, and the movement trajectory of the sliding block 39 is opposite to the movement trajectory of the rectangular frame 34. Therefore, when the driving motor 36 is started, the two piston rods 20 can be driven to move relative to each other at the same time, so that the two pistons 21 can slide relative to each other in the corresponding piston tube 15. Through the alternating movement of the two pistons 21, continuous transportation of mud can be achieved.

[0049] Example 3

[0050] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 6 As shown, an upper notch 6 is provided on one side of the top of the two mounting seats 1, and two lower notches 17 are symmetrically provided on both sides of the bottom of the bottom plate 4, which are used in conjunction with the two upper notches 6 respectively. The bottom wall of the upper notch 6 is provided with a plurality of first connection holes 11 arranged side by side and equidistantly, and the top wall of the lower notch 17 is provided with at least one second connection hole 18, and the first connection hole 11 and the second connection hole 18 are connected by a first connection bolt 19. When installing the driving mechanism, the bottom plate 4 is overlapped on the two mounting seats 1 through the cooperation of the upper notch 6 and the lower notch 17, and the bottom of the bottom plate 4 is flush with the bottom of the mounting seat 1, which is convenient for overall installation and placement; then the mounting seat 1 is fixedly connected to the bottom plate 4 by the first connection bolt 19, thereby completing the connection and fixation of the entire pump body base.

[0051] Example 4

[0052] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 10As shown, one side of the rectangular frame 34 and the sliding block 39 are fixedly connected with a connecting rod 32, one end of the two connecting rods 32 slides through one side of the protective cover 16 and is fixedly connected with a sleeve 22 through a third connecting bolt 33, and one end of the two sleeves 22 is respectively slidably sleeved on the outer wall of the two piston rods 20 away from the piston 21. In the process of the rectangular frame 34 and the sliding block 39 moving back and forth, the corresponding sleeve 22 can be driven to move back and forth by the connecting rod 32, thereby driving the piston rod 20 to move back and forth. The top of the outer wall of the piston rod 20 is fixedly connected with a fixed shaft 25, and the sleeve 22 is fixedly connected to the top of the outer wall of the piston rod 20. 2 is provided with a strip hole 28, and the top end of the fixed shaft 25 passes through the strip hole 28 and extends upward, the top end of the fixed shaft 25 is symmetrically fixedly connected with two support blocks 26, and the tops of the two support blocks 26 are provided with upper connecting holes 27, and the outer wall of the sleeve 22 is equidistantly provided with multiple groups of connecting blocks 29 used in conjunction with the support blocks 26, each group of connecting blocks 29 has two in number, and are symmetrically arranged on both sides of the strip hole 28, and the tops of the multiple connecting blocks 29 are provided with lower connecting holes 30, and the upper connecting holes 27 correspond to the lower connecting holes 30 and are connected by second connecting bolts 31.First, overlap the bottom plate 4 on the mounting base 1 through the cooperation of the upper notch 6 and the lower notch 17, and adjust the appropriate installation position so that the first connecting hole 11 corresponds to the second connecting hole 18, and then fix the bottom plate 4 and the mounting base 1 with the first connecting bolt 19, so that the size of the installation volume of the entire pump body can be adjusted, which can adapt to installation and use in different environments and improve the flexibility of installation; after the entire driving mechanism is installed, the connecting rod 32 and the sleeve 22 are fixedly connected by the third connecting bolt 33. After the connection, the piston rod 20 is pulled outward in the sleeve 22, and the piston 21 is inserted into the piston tube 15. In the process of pulling the piston rod 20 outward, the fixed shaft 25 moves in the strip hole 28, and at the same time drives the support block 26 to move. At this time, according to the installation position of the bottom plate 4, that is, the corresponding position of the first connecting hole 11 and the second connecting hole 18, the installation length of the piston rod 20 can be judged, and the corresponding connection can be selected. The connecting position of the block 29 is then connected and fixed to the support block 26 and the connecting block 29 by the second connecting bolt 31, so that different connection lengths between the piston rod 20 and the sleeve 22 can be adapted to different installation positions of the drive motor 36, and the connection can be accurately positioned for easy installation, thereby ensuring the normal piston movement of the piston 21; on the contrary, when the piston 21 needs to be replaced, the third connecting bolt 33 is first removed, the connection between the sleeve 22 and the connecting rod 32 is removed, and then the second connecting bolt 31 is removed, and the piston rod 20 is pulled outward to be taken out; and when removing a set of piston mechanisms, another set of piston mechanisms can be used for mud transportation, which can continue to ensure the normal progress of the work; similarly, when the drive mechanism needs to be dismantled, repaired and replaced, it is only necessary to remove the third connecting bolt 33, remove the connection between the sleeve 22 and the connecting rod 32, and then remove the first connecting bolt 19, and remove the connection between the bottom plate 4 and the mounting seat 1.

[0053] A method for using a highly wear-resistant mud pump capable of modular splicing, comprising the following steps:

[0054] S1. First, overlap the bottom plate on the mounting seat through the cooperation of the upper notch and the lower notch, and adjust the appropriate mounting position so that the first connecting hole corresponds to the second connecting hole, and then fix the bottom plate and the mounting seat with the first connecting bolt;

[0055] S2, then, the connecting rod is fixedly connected to the sleeve by the third connecting bolt. After the connection is completed, the piston rod is pulled outward in the sleeve, and the piston is inserted into the piston tube. According to the installation position of the bottom plate, the installation length of the piston rod is determined, and the connection position of the corresponding connecting block is selected. Then, the support block and the connecting block are connected and fixed by the second connecting bolt, so as to complete the detachable connection between the piston rod and the driving mechanism;

[0056] S3. Finally, the driving motor is started to drive the rectangular frame and the sliding block to move relative to each other, and then the two pistons are driven to slide relative to each other through the corresponding connecting rod, sleeve and piston rod, so that the mud enters the conveying pipe from the feed pipe, enters the hollow column through the guide pipe, and is finally transported out from the discharge pipe to complete the transportation of the mud.

[0057] The above embodiments are only used to help understand the method and core idea of ​​the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
