Description

Technical Field

[0001] This invention relates to the field of engineering equipment, specifically an adaptive regulating energy-saving reciprocating mud pump. Background Technology

[0002] In the field of engineering construction, reciprocating mud pumps are the core equipment for mud transportation, widely used in scenarios such as building piling, geological exploration, and mining. Their working principle mainly relies on the reciprocating motion of a piston within a sealed sleeve to achieve the extraction and discharge of mud. The frictional losses between the piston and the inner wall of the sleeve, and between the connecting rod and the sealing structure, directly affect the operational stability and service life of the equipment.

[0003] Existing reciprocating mud pumps have the following problems: First, the pump body has a fixed operating stroke and cannot adaptively adjust according to changes in the actual mud volume. When the mud volume decreases, the pressure inside the pump will rise abnormally, resulting in energy waste due to excessive pressure. At the same time, excessive pressure will also affect the mud conveying efficiency and even cause equipment failure, reducing the continuity of construction. Second, the lubrication system is poorly designed. The lubricating oil cannot simultaneously achieve lubrication, wear prevention, recovery, filtration, and reuse when adjusting according to the pump body's operating stroke. This not only wastes lubricating oil but also exacerbates component wear due to impurities, leading to frequent replacement of vulnerable parts such as pistons and sealing sleeves, increasing operating costs. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, the pump body has a fixed operating stroke and cannot adaptively adjust according to changes in the actual mud volume. When the mud volume decreases, the pressure inside the pump will rise abnormally, resulting in energy waste due to excessive pumping. This invention proposes an adaptive adjustment energy-saving reciprocating mud pump.

[0005] The technical solution adopted by this invention to solve its technical problem is: an adaptive adjustment energy-saving reciprocating mud pump as described in this invention, comprising:

[0006] A support platform, the top of which is fixedly connected to a protective shell, the top of which is equipped with a receiver and a controller, and a slide is fixedly connected to the middle of the top of the support platform;

[0007] The pumping mechanism, installed outside the support platform, is used for reciprocating extraction and discharge of mud.

[0008] The drive mechanism, which is installed outside the support platform, is used to drive the pumping mechanism to operate;

[0009] An adaptive adjustment mechanism, installed inside the support platform, is used to adaptively adjust the pressure generated inside the pumping mechanism;

[0010] The lubrication mechanism, installed outside the pumping mechanism, is used to reduce friction inside the pumping mechanism and to recover and filter lubricating oil.

[0011] The pumping mechanism includes three sealing sleeves, all of which are fixedly connected to the support platform. A piston is movably connected to the inner cavity of each sealing sleeve. A pull rod is fixedly connected to one side of each piston. A circular hole adapted to the pull rod is opened through the left side of each sealing sleeve. A T-rod is fixedly connected to the left side of each of the three pull rods. A housing is fixedly connected to the left side of each T-rod. A slot adapted to the slide is opened at the bottom of the housing. Slots are opened on both sides of the inner wall of the housing. A locking block adapted to the locking slot is fixedly connected to the left side of each T-rod. A rack is fixedly connected to the front of the locking block. Mounting groove one and mounting groove two are respectively opened on one side of each of the three pull rods and around the outer ring of piston one.

[0012] Preferably, the top and bottom of the sealing sleeve are respectively fitted with a suction pipe and a discharge pipe. The inner walls of the suction pipe and the discharge pipe are provided with U-shaped seats. The inner cavity of the U-shaped seats is rotatably connected to a rotatable rod through a bearing. The outer ring of the rotatable rod is fitted with a baffle plate. One of the sealing sleeves is provided with a pressure sensor at its top. The pressure sensor is electrically connected to a receiver and a controller. The three sealing sleeves are connected to each other through two through pipes.

[0013] Preferably, the drive mechanism includes a motor fixedly connected to the top of the support platform and an annular shell. The inner wall of the annular shell is rotatably connected to a rotating rod via a bearing. A first synchronous pulley and a second synchronous pulley are respectively mounted on the rotating rod and the output shaft of the motor. A belt is movably connected to the outside of the second synchronous pulley and the first synchronous pulley. A connecting rod is fixedly connected to the front of the first synchronous pulley. The connecting rod is rotatably connected to the outer shell via a bearing. A drive gear is mounted on the outer ring of the output shaft of the motor.

[0014] Preferably, the connection between the belt and the first and second synchronous pulleys is frosted.

[0015] Preferably, the adaptive adjustment mechanism includes a horizontal plate fixedly connected to the inner wall of one side of the support platform. A hydraulic push rod is fixedly connected to the top left side of the horizontal plate. The hydraulic push rod is electrically connected to the controller. An L-shaped plate is provided at the output end of the hydraulic push rod and the top right side of the horizontal plate. The inner walls of the two L-shaped plates are respectively rotatably connected to two rods (rod one and rod two) through bearings. A sprocket is fitted on the outer ring of one of the rods (rod one and rod two). A chain is movably connected to the outside of the two sprockets.

[0016] Preferably, each of the first rods is provided with a driven gear, and the second rod is fixedly connected with a driven gear, and the driven gear and the driven gear are meshed together.

[0017] Preferably, the lubrication mechanism includes three oil storage chambers, three oil supply pipes, and three sets of oil outlet pipes. The three oil storage chambers are fixedly connected to the left side of three sealing sleeves. The three oil supply pipes and the three sets of oil outlet pipes are respectively arranged in three mounting slots and three sets of mounting slots. The three oil supply pipes and the corresponding three sets of oil outlet pipes are interconnected. The inner wall of each oil storage chamber is rotatably connected to a rotating rod through a bearing. A sealing cover is fitted on the outer ring of the rotating rod. An inclined plate supporting the sealing cover is fixedly connected to the inner wall of each oil storage chamber. An oil filling pipe is sleeved on the top of each of the three oil storage chambers. A flexible hose is sleeved between each oil storage chamber and the oil supply pipe. A piston is movably connected to the inner cavity of each oil storage chamber. An L-shaped rod is fixedly connected between each piston and the pull rod.

[0018] Preferably, a filter box is fixedly connected to the right side of each oil storage tank, a filter screen is fixedly connected to the inner cavity of each filter box, and a return pipe is sleeved between the top of each filter box and the bottom of each oil storage tank.

[0019] Preferably, the filter screens are all made of stainless steel, and the bottom of each filter box is provided with a discharge hole, the inner cavity of which is threadedly connected with a threaded cap.

[0020] The advantages of this invention are:

[0021] When the amount of mud decreases, causing the pressure inside the sealing sleeve to increase, the pressure sensor can detect this in real time and feed the signal back to the controller via a receiver. The controller then drives the hydraulic push rod to adjust the position of the L-shaped plate, causing the driven gear to mesh with the driving gear. This, in turn, changes the initial position of the piston inside the sealing sleeve through gear and rack transmission, shortening the piston's travel distance. This process automatically adapts to changes in mud volume, avoiding energy waste caused by excessive pressure and preventing damage to the equipment. It significantly improves the equipment's adaptability under different mud volume conditions, reducing energy waste and the risk of equipment failure.

[0022] This invention utilizes a two-pronged approach: firstly, the reciprocating motion of the pull rod moves the L-shaped rod and piston within the oil reservoir. Combined with the opening and closing of the sealing cap, this allows for precise delivery of lubricating oil via hoses, supply pipes, and outlet pipes to the friction points between the piston and the sealing sleeve, reducing component friction wear. Secondly, excess lubricating oil flows back into the filter box through a return pipe. The stainless steel filter screen efficiently filters impurities, and the clean lubricating oil is returned to the oil reservoir for recycling. Furthermore, the drain hole and threaded cap at the bottom of the filter box facilitate regular cleaning of impurities, preventing secondary contamination of the lubricating oil. This design not only reduces lubricating oil consumption but also lowers the replacement frequency of vulnerable parts such as the piston and sealing sleeve, significantly extending equipment lifespan and reducing user operating costs.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1 and Figure 2 As shown, an adaptive regulating energy-saving reciprocating mud pump includes:

[0040] The platform 100 has a protective shell 101 fixedly connected to its top. A receiver 102 and a controller 103 are mounted on the top of the protective shell 101. A slide 104 is fixedly connected to the middle of the top of the platform 100. A pumping mechanism 200 is installed outside the platform 100 for reciprocating extraction and discharge of mud. A drive mechanism 300 is installed outside the platform 100 for driving the pumping mechanism 200. An adaptive adjustment mechanism 400 is installed inside the platform 100 for adaptively adjusting the pressure inside the pumping mechanism 200. A lubrication mechanism 500 is installed outside the pumping mechanism 200 for reducing friction inside the pumping mechanism 200 and recovering filtered lubricating oil.

[0041] Furthermore, existing equipment operates on a fixed stroke, which not only makes it impossible to adjust energy consumption but also results in excessive pressure, affecting performance and increasing operating costs.

[0042] like Figure 1 and Figure 6As shown, the drive mechanism 300 further includes a motor 301 fixedly connected to the top of the support platform 100 and an annular housing 302. A rotating rod 303 is rotatably connected to the inner wall of the annular housing 302 via bearings. A first synchronous pulley 304 and a second synchronous pulley 305 are respectively mounted on the rotating rod 303 and the output shaft of the motor 301. A belt 306 is movably connected to the outer side of the second synchronous pulley 305 and the first synchronous pulley 304. A connecting rod 307 is fixedly connected to the front of the first synchronous pulley 304. The connecting rod 307 is rotatably connected to the outer housing 211 via bearings. A drive gear 308 is mounted on the outer ring of the output shaft of the motor 301. The belt 306 is rotatably connected to the first synchronous pulley 304 via bearings. The connection between the pulley 304 and the second synchronous pulley 305 is frosted. The motor 301 is used as the power source to drive the second synchronous pulley 305 and the drive gear 308 to rotate. When the second synchronous pulley 305 rotates, it drives the first synchronous pulley 304, the connecting rod 307 and the rotating rod 303 to rotate via the belt 306. During the rotation of the connecting rod 307, the pumping mechanism 200 is driven to extract and discharge mud. Since the connection between the belt 306 and the first synchronous pulley 304 and the second synchronous pulley 305 is frosted, the friction can be increased during the driving process, thereby improving the stability of the drive mechanism 300 driving the pumping mechanism 200.

[0043] like Figure 3 and Figure 4 as well as Figure 5As shown, the pumping mechanism 200 further includes three sealing sleeves 201, all of which are fixedly connected to the support platform 100. A piston 207 is movably connected to the inner cavity of each sealing sleeve 201. A pull rod 208 is fixedly connected to one side of each piston 207. A circular hole 209 adapted to the pull rod 208 is opened through the left side of each sealing sleeve 201. A T-rod 210 is fixedly connected to the left side of each of the three pull rods 208. A housing 211 is fixedly connected to the left side of each T-rod 210. A slot adapted to the slide table 104 is opened at the bottom of the housing 211. Slots 212 are opened on both sides of the inner wall of the housing 211. A locking block 213 adapted to the locking slot 212 is fixedly connected to the left side of the T-rod 210. A rack 214 is fixedly connected to the front of the locking block 213. Mounting grooves are opened on one side of each of the three pull rods 208 and around the outer ring of each piston 207. 215 and mounting groove 216; the top and bottom of the sealing sleeve 201 are respectively fitted with a suction pipe 202 and a discharge pipe 203. The inner walls of the suction pipe 202 and the discharge pipe 203 are provided with U-shaped seats 204. The inner cavity of the U-shaped seat 204 is rotatably connected to a rotatable rod 205 through a bearing. The outer ring of the rotatable rod 205 is fitted with a baffle 206. A pressure sensor 217 is provided at the top of one of the sealing sleeves 201. The pressure sensor 217 is electrically connected to the receiver 102 and the controller 103 (using a PLC controller) (i.e., the controller 103 has a preset pressure threshold). When the pressure value detected by the pressure sensor 217 exceeds the threshold, the controller 103 determines that the current working condition is low flow and high load, and then starts the hydraulic push rod 402. This creates a preset mapping relationship between the lifting stroke of the hydraulic push rod 402 and the shortening amount of the target piston stroke.Specifically, the overall system can adopt a PID control algorithm (an existing algorithm, so it will not be described in detail in the manual), which dynamically adjusts the lifting and lowering of the hydraulic push rod in real time according to the pressure deviation to find and maintain an optimal working point with the lowest energy consumption. The three sealing sleeves 201 are connected by two through pipes. When the connecting rod 307 rotates through the first synchronous pulley 304 to generate circular motion, since the bottom of the outer shell 211 has a slot that matches the slide table 104, it will drive the outer shell 211 connected by the bearing and the internal locking block 213 to convert into reciprocating linear motion on the slide table 104 at the top of the support platform 100. The linear motion of the locking block 213 will drive the T rod 210 and cause the pull rod 208 to... The piston 207 moves back and forth within the circular hole 209 on the corresponding sealing sleeve 201. When moving backward, pressure is generated, causing the baffle 206 in the extraction pipe 202 to rotate upward via the rotatable rod 205. After rotating upward, the extraction pipe 202 is opened to draw in the slurry. When the piston 207 moves forward, the baffle 206 in the extraction pipe 202 is reset, causing the extraction pipe 202 to close. At the same time, the baffle 206 in the discharge pipe 203 is rotated upward via the rotatable rod 205, opening the discharge pipe 203 to discharge the drawn-in slurry. Due to the reciprocating linear motion of the T-rod 210 and the locking block 213 connected to the pull rod 208, the slurry is continuously extracted and discharged in a reciprocating manner.

[0044] like Figure 5 and Figure 7As shown, the adaptive adjustment mechanism 400 further includes a horizontal plate 401 fixedly connected to the inner wall of one side of the support platform 100. A hydraulic push rod 402 is fixedly connected to the top left side of the horizontal plate 401. The hydraulic push rod 402 is electrically connected to the controller 103. An L-shaped plate 403 is provided at the output end of the hydraulic push rod 402 and the top right side of the horizontal plate 401. The inner walls of the two L-shaped plates 403 are respectively rotatably connected to two rods 404 and one rod 405 through bearings. A sprocket 406 is fitted on the outer ring of both rods 404 and rod 405. A chain 407 is movably connected to the outside of the two sprockets 406. A driven gear is provided on each rod 404. A driven gear 409 is fixedly connected to rod 405. Driven gear 409 meshes with driven gear 408. When the amount of mud decreases during extraction and discharge, the pressure inside the sealing sleeve 201 increases. Since the three sealing sleeves 201 are interconnected, the pressure generated is detected by pressure sensor 217. When the pressure increases, pressure sensor 217 sends a signal, which is received by receiver 102 on the support platform 100. After receiving the signal, it is fed back to controller 103, which then drives the hydraulic push rod 402. During this drive, the output end of the push rod is connected to the hydraulic push rod. The L-shaped plate 403 moves upward a certain distance, causing the driven gear 408 on the outer ring of one of the rods 404 on the L-shaped plate 403 to mesh with the driving gear 308. The hydraulic push rod 402 then stops driving. Since the driving gear 308 rotates synchronously with the output shaft of the motor 301, it drives the meshed driven gear 408 to rotate. This rotation drives the driven gear 408 on the outer ring of the other rod 404 and the sprocket 406 to rotate. Subsequently, the chain 407 drives the sprocket 406 on the second rod 405 and the driven gear 409 to rotate together. Because the driven gear 409 meshes with the rack 214 on the locking block 213... When the driven gear 209 rotates, it drives the rack 214 to make the locking block 213 slide backward in the locking groove 212. When sliding, the piston 207 located in the sealing sleeve 201 moves backward together. When it moves to the appropriate position, the hydraulic push rod 402 opens. After opening, the corresponding L-shaped plate 403 and the driven gear 408 meshing with the driving gear 308 move down to cancel the meshing. (As a preferred embodiment, an electromagnetic clutch can be provided between the driven gear 408 and the driving gear 308. When the stroke needs to be adjusted, the controller 103 connects the electromagnetic clutch circuit, and power is transmitted. After the adjustment is completed, the circuit is disconnected and the power is separated.)Based on this, we can achieve rapid and smooth power engagement and disengagement, avoid hard gear impact, and improve system life and adjustment accuracy. When the position of piston 207 in the sealing sleeve 201 moves backward, the stroke of piston 207 within the sealing sleeve 201 will be shortened. After the shortening, the increased pressure will be reduced when pumping and discharging mud, preventing the adverse situation of excessive energy consumption caused by a large load pulling a small load when the mud volume decreases. Thus, this device can achieve adaptive adjustment and energy saving.

[0045] like Figure 4 and Figure 8 as well as Figure 9As shown, the lubrication mechanism 500 further includes three oil reservoirs 501, three oil supply pipes 502, and three sets of oil outlet pipes 503. The three oil reservoirs 501 are fixedly connected to the left side of the three sealing sleeves 201. The three oil supply pipes 502 and the three sets of oil outlet pipes 503 are respectively arranged in three mounting slots 1 215 and three sets of mounting slots 216. The three oil supply pipes 502 and the corresponding three sets of oil outlet pipes 503 are interconnected. The inner wall of each oil reservoir 501 is rotatably connected to a rotating rod 504 via bearings. A sealing cover 505 is fitted on the outer ring of the rotating rod 504. An inclined plate 506 supporting the sealing cover 505 is fixedly connected to the inner wall of each oil reservoir 501. An oil filling pipe is sleeved on the top of each of the three oil reservoirs 501. 507. A hose 508 is fitted between the oil storage tank 501 and the oil delivery pipe 502. A piston 509 is movably connected to the inner cavity of the oil storage tank 501. An L-shaped rod 510 is fixedly connected between the piston 509 and the pull rod 208. When the pull rod 208 and the piston 207 move backward within the sealing sleeve 201, they will simultaneously drive the L-shaped rod 510 and the piston 509 to move backward within the oil storage tank 501. During the backward movement, the sealing cover 505 in the oil storage tank 501 will rotate to the right via the rotating rod 504, opening the oil storage tank 501. After opening, the lubricating oil in the oil storage tank 501, located above the sealing cover 505, flows downward and then enters the oil delivery pipe 502 and the oil outlet pipe 503 through the hose 508. Finally, the lubricating oil flows between the outer wall of piston 207 and the inner wall of the sealing sleeve 201. After flowing to the inner wall, during the movement of piston 207, the lubricating oil is evenly coated between piston 207 and the inner wall of the sealing sleeve 201, providing lubrication. Furthermore, as the pull rod 208 and piston 207 move forward within the sealing sleeve 201, they simultaneously drive the L-shaped rod 510 and piston 509 to move forward within the oil reservoir 501, causing the sealing cap 505 in the oil reservoir 501 to reset and close the oil reservoir 501. Simultaneously, the oil outlet pipe 503 and the oil delivery pipe 502 draw excess lubricating oil back into the return pipe 513, from where it enters the filter box 511, and finally flows back into the oil reservoir 501. This device enables the lubrication and anti-wear function of the sealing sleeve 201, while also recovering and reusing excess lubricating oil. This prevents the pumping mechanism 200 from requiring frequent replacements of piston 207 and sealing sleeve 201 after a period of operation, thus avoiding unnecessary costs. (When the pull rod 208 moves piston 509 backward, it squeezes the lubricating oil in the oil reservoir 501, forcing a fixed amount of lubricating oil through the hose 508 and oil delivery pipe 502, and finally spraying it out from the oil outlet pipe 503, precisely coating the inner wall of the sealing sleeve 201.) This ensures that lubrication occurs immediately upon operation, avoiding ineffective lubrication and lubricating oil waste. Combined with adaptive energy-saving regulation, this reduces the overall operating cost of the equipment.

[0046] Continue with Figure 8 and Figure 9As shown, furthermore, a filter box 511 is fixedly connected to the right side of the oil storage tank 501, and a filter screen 512 is fixedly connected to the inner cavity of the filter box 511. A return pipe 513 is sleeved between the top of the filter box 511 and the bottom of the oil storage tank 501. The filter screens 512 are all made of stainless steel. A discharge hole 514 is opened at the bottom of the filter box 511. A threaded cap 515 is threadedly connected to the inner cavity of the discharge hole 514. When the lubricating oil flows back to the filter box 511, it will pass through the filter screen 512 to filter and block the impurities contained therein, thereby preventing impurities from flowing back into the oil storage tank 501 with the lubricating oil and causing unnecessary impact on the work of recycling and reusing lubricating oil to reduce consumption. After a period of use, the threaded cap 515 can be screwed off to open the discharge hole 514, so that the impurities blocked by the filter can be discharged from the filter box 511 for subsequent normal use.
