Description

Technical Field

[0001] The utility model belongs to the technical field of triplex plunger pumps and relates to a triplex plunger pump, in particular to a triplex plunger pump with a stable supporting function. Background Art

[0002] The plunger pump is an important device in the hydraulic system. Its working mainly relies on the reciprocating motion of the plunger in the cylinder to change the volume in the working chamber to achieve the work of sucking and pressing the liquid. The three-cylinder plunger pump is mainly used in agriculture for high-pressure spraying or high-pressure irrigation due to its simple structure.

[0003] The existing three-cylinder plunger pump is generally used in fields, where it is used for spraying or irrigation. The supporting legs of the three-cylinder plunger pump are directly placed on the ground. However, it is generally difficult to have a flat ground in these scenes, which makes it difficult to place the three-cylinder plunger pump stably. When the three-cylinder plunger pump vibrates during operation, it will move in a tilted direction, or the entire three-cylinder plunger pump may topple over.

[0004] After searching, it is found that a three-cylinder plunger pump with a stable support function is disclosed in Chinese patent documents [Application No.: 202321196868.4; Publication No.: CN 219974704 U]. A three-cylinder plunger pump with a stable support function, which relates to the research and development field of three-cylinder plunger pumps, includes a three-cylinder plunger pump body, one end of the three-cylinder plunger pump body is fixed with a water inlet bin, a filtering mechanism is arranged in the water inlet bin, and four rectangularly distributed supporting legs are fixed on the three-cylinder plunger pump body, and an adjustment mechanism is arranged on the supporting legs. The three-cylinder plunger pump body is placed in the required position, and then the height of the supporting legs is adjusted by the adjustment mechanism, so that the three-cylinder plunger pump body is placed stably, and the driving wheel is driven to rotate by an external motor. The water in the pool enters the water inlet bin by a water pipe, and the filtering mechanism of the water inlet bin filters the water drawn from the pool, so that the three-cylinder plunger pump body can be stably supported in the field, reducing the possibility of tilting or instability of the placement, and making the three-cylinder plunger pump body tip over when working.

[0005] Although this patent allows the three-cylinder plunger pump body to be stably supported in the field, reducing tilt or instability, the three-cylinder plunger pump itself is heavy, and it is cumbersome and difficult to manually adjust the supporting legs one by one. In addition, the field environment is mostly muddy, and people who want to make manual adjustments mostly need to stand at the edge of the field, which can easily cause the risk of slipping and falling. Utility Model Content

[0006] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a three-cylinder plunger pump with a stable support function. The technical problem to be solved by the utility model is: how to automatically and efficiently make corresponding adjustments according to the ground clearance of four support points to complete the stable support work.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A three-cylinder plunger pump with a stabilizing support function comprises a plunger pump body and two stabilizing frames arranged at the bottom of the plunger pump body, a pair of stabilizing plates are arranged at the bottom of the two stabilizing frames, and a pair of stabilizing rods are vertically fixed on each pair of stabilizing plates, and the top of each pair of stabilizing rods passes through the corresponding stabilizing frames, and limiting assemblies for fixing each pair of stabilizing rods are arranged in the two stabilizing frames, and electric push rods are fixed in the two stabilizing frames, and the output ends of the two electric push rods are respectively fixedly connected to the corresponding stabilizing plates.

[0009] The working principle of the utility model is: the corresponding stabilizing plates can be pushed to contact the ground through four electric push rods, so as to fit the uneven ground, improve the stability of the plunger pump body during operation, and will not appear the phenomenon of tipping over during operation due to unstable grounding, and improve the application scenario, and maintain the operation flow of the corresponding stabilizing plates through two stabilizing bars, and the two stabilizing bars can be fixed through the limit assembly, so as to realize the ability to cooperate with the electric push rod to improve the strength of the supporting structure.

[0010] Four damping rods are fixed to the bottom of the plunger pump body, and the four damping rods are divided into a group of two, and the bottom of each group of damping rods is fixedly connected to the corresponding stabilizing frame, and shock-absorbing springs are sleeved on the four damping rods, and the top ends of the four shock-absorbing springs are fixedly connected to the bottom of the plunger pump body, and the bottom ends of the four shock-absorbing springs are fixedly connected to the top surface of the corresponding stabilizing frame.

[0011] By adopting the above structure, the damping rod can be used as the connecting structure between the plunger pump body and the two stabilizing frames, and the shock-absorbing spring can be used to reduce the vibration of the stabilizing frame caused by the operation of the plunger pump body, thereby ensuring the stability of the utility model. The stabilizing frame reduces the vibration, and when connected to the bottom surface, it is also easy to ensure that the ground structure will not become loose due to the vibration, thereby further improving the stability performance.

[0012] The limit assembly includes a pair of pressure blocks slidably connected in two stabilizing frames, a bidirectional lead screw rotatably connected in the two stabilizing frames, a transmission gear coaxially fixed in the middle of the two bidirectional lead screws, a driving motor fixed in the two stabilizing frames, a driving gear coaxially fixed at the output ends of the two driving motors, the two driving gears are respectively meshed with the corresponding driving gears, and the two ends of the two bidirectional lead screws are respectively threadedly connected to the corresponding pressure blocks, and the four pressure blocks are respectively clamped and cooperated with a corresponding set of stabilizing bars.

[0013] By adopting the above structure, the driving motor can be used to drive the driving gear to rotate. When the driving gear rotates, it will drive the transmission gear to rotate. When the transmission gear rotates, it will drive the bidirectional lead screw to operate. The bidirectional lead screw then drives the pressure blocks at both ends to squeeze and fix the corresponding pair of stabilizer bars, thereby limiting the position of the stabilizer bars, thereby realizing the ability to cooperate with the electric push rod to improve the strength of the supporting structure.

[0014] A pair of laser rangefinders are fixed on the two stable frames, and controllers are fixed in the two stable frames. The two controllers are electrically connected to the corresponding pair of laser rangefinders, and the two controllers are electrically connected to the corresponding pair of electric push rods.

[0015] With the above structure, the distance between the two sides of the stabilizer frame and the ground can be sensed by a laser rangefinder, and the information can be transmitted to the controller for processing. The controller controls the electric push rod to extend to the corresponding amplitude through the information, thereby ensuring that the corresponding support work is automatically and efficiently performed according to the ground clearance.

[0016] A plurality of thorns are fixed on the bottom surfaces of the two pairs of stabilizing plates.

[0017] By adopting the above structure, the connection depth between the stabilizing plate and the ground can be improved by stabbing when the stabilizing plate contacts the ground, thereby improving the fixing stability of the fixing point with the ground during support.

[0018] Compared with the prior art, the three-cylinder plunger pump with stable support function has the following advantages:

[0019] 1. Use four electric push rods to push the corresponding stabilizing plates to contact the ground, so as to fit the uneven ground, improve the stability of the plunger pump body during operation, and prevent the phenomenon of tipping over during operation due to unstable grounding, and improve the application scenarios.

[0020] 2. The laser rangefinder senses the distance between the two sides of the stabilizer frame and the ground, and transmits the information to the controller for processing. The controller controls the electric push rod to extend to the corresponding range through the information, so as to ensure that the corresponding support work is automatically and efficiently carried out according to the ground clearance.

[0021] 3. Two stabilizer bars are used to maintain the operational flow of the corresponding stabilizer plate, and the two stabilizer bars can be fixed by the limit assembly to achieve the ability to cooperate with the electric push rod to improve the strength of the supporting structure.

DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] like Figure 1-Figure 4 As shown, a three-cylinder plunger pump with a stabilizing support function includes a plunger pump body 1, two stabilizing frames 2 arranged at the bottom of the plunger pump body 1, a pair of stabilizing plates 3 are arranged at the bottom of the two stabilizing frames 2, and a pair of stabilizing rods 4 are vertically fixed on each pair of stabilizing plates 3, and the top of each pair of stabilizing rods 4 passes through the corresponding stabilizing frames 2, and the two stabilizing frames 2 are provided with limiting components for fixing each pair of stabilizing rods 4, and the two stabilizing frames 2 are fixed with electric push rods 5, and the output ends of the two electric push rods 5 are fixedly connected to the corresponding stabilizing plates 3 respectively.

[0029] The four electric push rods 5 can push the corresponding stabilizing plates 3 to contact the ground, so as to fit the uneven ground, improve the stability of the plunger pump body 1 during operation, and prevent the phenomenon of tipping over during operation due to unstable grounding, thereby improving the application scenario, and maintaining the operation flow of the corresponding stabilizing plates 3 through two stabilizing bars 4, and the two stabilizing bars 4 can be fixed through the limit assembly, so as to achieve the ability to cooperate with the electric push rods 5 to improve the strength of the supporting structure.

[0030] Four damping rods 6 are fixed to the bottom of the plunger pump body 1, and the four damping rods 6 are divided into a group of two, and the bottom of each group of damping rods 6 is fixedly connected to the corresponding stabilizing frame 2, and shock-absorbing springs 7 are sleeved on the four damping rods 6, and the top ends of the four shock-absorbing springs 7 are fixedly connected to the bottom of the plunger pump body 1, and the bottom ends of the four shock-absorbing springs 7 are fixedly connected to the top surface of the corresponding stabilizing frame 2.

[0031] By adopting the above structure, the damping rod 6 can be used as the connecting structure between the plunger pump body 1 and the two stabilizing frames 2, and the shock-absorbing spring 7 can be used to reduce the vibration caused by the plunger pump body 1 on the stabilizing frames 2 during operation, thereby ensuring the stability of the utility model. The stabilizing frames 2 reduce the vibration, and when connected to the bottom surface, it is also easy to ensure that the ground structure will not become loose due to the vibration, thereby further improving the stability performance.

[0032] The limiting assembly includes a pair of pressure blocks 8 slidingly connected in the two stabilizing frames 2, and a bidirectional lead screw 9 rotatably connected in the two stabilizing frames 2. A transmission gear 10 is coaxially fixed in the middle of the two bidirectional lead screws 9. A driving motor 11 is fixed in the two stabilizing frames 2. A driving gear 12 is coaxially fixed at the output ends of the two driving motors 11. The two driving gears 12 are respectively meshed with the corresponding driving gears 12, and the two ends of the two bidirectional lead screws 9 are respectively threadedly connected to the corresponding pressure blocks 8. The four pressure blocks 8 are respectively clamped and cooperated with a corresponding set of stabilizing bars 4.

[0033] By adopting the above structure, the driving motor 11 can be used to drive the driving gear 12 to rotate. When the driving gear 12 rotates, it will drive the transmission gear 10 to rotate. When the transmission gear 10 rotates, it will drive the bidirectional lead screw 9 to operate. The bidirectional lead screw 9 then drives the pressure blocks 8 at both ends to squeeze and fix the corresponding pair of stabilizing bars 4, thereby limiting the position of the stabilizing bars 4, thereby realizing the ability to cooperate with the electric push rod 5 to improve the strength of the supporting structure.

[0034] A pair of laser rangefinders 13 are fixed on the two stabilizing frames 2, and a controller 14 is fixed inside the two stabilizing frames 2. The two controllers 14 are electrically connected to the corresponding pair of laser rangefinders 13, and the two controllers 14 are electrically connected to the corresponding pair of electric push rods 5.

[0035] By adopting the above structure, the distance between the two sides of the stabilizer frame 2 and the ground can be sensed by the laser rangefinder 13, and the information can be transmitted to the controller 14 for processing. The controller 14 controls the electric push rod 5 to extend to the corresponding amplitude through the information, thereby ensuring that the corresponding support work is automatically and efficiently performed according to the ground clearance.

[0036] A plurality of spikes 15 are fixed to the bottom surfaces of the two pairs of stabilizing plates 3 .

[0037] By adopting the above structure, the stabbing 15 can improve the connection depth between the stabilizing plate 3 and the ground when it contacts the ground, and improve the fixing stability of the fixing point with the ground during support.

[0038] The working principle of the utility model is as follows: the plunger pump body 1 is placed at the desired position, and the surrounding terrain is sensed by the laser rangefinder 13 at this time, and the surrounding data is transmitted to the controller 14 for processing. The controller 14 then drives the four electric push rods 5 through the data to push the corresponding support plates downward until the plunger pump body 1 maintains a horizontal and stable state, and then drives the drive motor 11 to drive the drive gear 12 to rotate. After the drive gear 12 rotates, it will drive the transmission gear 10 to rotate. After the transmission gear 10 rotates, it will drive the bidirectional lead screw 9 to operate. The bidirectional lead screw 9 then drives the pressure blocks 8 at both ends to squeeze and fix the corresponding pair of stabilizing bars 4, so as to limit the stabilizing bars 4, so as to achieve the ability to cooperate with the electric push rods 5 to improve the strength of the supporting structure.

[0039] In summary, the four electric push rods 5 push the corresponding stabilizing plates 3 to contact the ground, so as to fit the uneven ground, improve the stability of the plunger pump body 1 during operation, and prevent the phenomenon of tipping over during operation due to unstable grounding, and improve the application scenario. The two stabilizing bars 4 are used to maintain the operation flow of the corresponding stabilizing plates 3, and the two stabilizing bars 4 can be fixed by the limit assembly, so as to achieve the ability to cooperate with the electric push rods 5 to improve the strength of the supporting structure.
