Description

Technical Field

[0001] The invention relates to the technical field of a plunger pump mounting base, in particular to a conveniently adjustable base for a plunger pump. Background Art

[0002] The plunger pump is an important device in the hydraulic system. It belongs to reciprocating pumps and volumetric pumps. Its working principle is to rely on the reciprocating motion of the plunger in the cylinder to achieve the suction and discharge of liquid by changing the volume of the sealed working chamber. The plunger pump usually needs to be installed on the base before use, and then the base is installed in a suitable working area. The setting of the base not only facilitates the positioning of the pump body, but also ensures its stability during use.

[0003] It is difficult to ensure that the existing plunger pump base is set in a horizontal direction when in use. Due to the harsh installation environment, a sloped installation ground is often formed, and the base at the bottom of the pump body is usually flush with the pump body. This causes the pump body to tilt after actual installation, making it difficult to adapt to the installation operation of the fixed pipeline, causing considerable problems for the installers.

[0004] Therefore, we have designed a conveniently adjustable base for the plunger pump to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a conveniently adjustable base for a plunger pump to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides a conveniently adjustable base for a plunger pump, comprising a mounting base, a plunger pump body arranged above the mounting base, and a base plate fixedly installed at the bottom of the plunger pump body, including: The threaded screw is rotatably installed in the mounting base along the vertical direction, and a nut is threadedly sleeved on the threaded screw; The guide rod is arranged in a direction corresponding to the threaded screw rod, is rotatably mounted in the mounting base, and has a slide cylinder slidably sleeved thereon; Two L-shaped rods are fixedly mounted on one side of the nut and the slide tube, respectively, and the other end of the L-shaped rod slides through the mounting base and is movably connected to the bottom of the base plate; The driving member is arranged in the mounting base and is used for driving the nut and the slide cylinder to move up and down.

[0007] Furthermore, two fixing grooves are symmetrically provided at the bottom of the base plate, a sliding block is slidably arranged in the fixing groove, a mounting seat is fixedly installed at the bottom of the sliding block, and the L-shaped rod is rotatably arranged in the mounting seat.

[0008] Furthermore, a pin is provided in the mounting seat, and one end of the L-shaped rod is rotatably sleeved on the pin. By providing the pin, the L-shaped rod can be reasonably rotated and installed in the mounting seat, avoiding the problem of motion interference and reducing the installation work of the operator.

[0009] Furthermore, a guide rod is inserted into the sliding block, and both ends of the guide rod are fixedly installed and connected in the fixing groove, so that the sliding block can only slide along the direction set by the guide rod, avoiding the problem of sliding block movement deviation.

[0010] Furthermore, the driving member includes a motor, the motor is fixedly mounted on the inner top wall of the mounting base, a first gear is fixedly mounted on the driving shaft of the motor, a second gear is fixedly sleeved on the threaded screw, and the second gear is meshingly connected with the first gear.

[0011] Furthermore, it also includes a horizontal detection component for detecting the horizontal angle of the plunger pump body, the horizontal detection component at least includes a fixed box, the fixed box is fixedly installed on the front side of the bottom plate, a slider is slidably arranged in the fixed box, a spring is installed on the outside of the slider, the other end of the spring is installed in the fixed box, a pressing piece is fixedly installed on the top of the slider, an electromagnetic button is inlaid on the top wall of the fixed box, the electromagnetic button and the pressing piece are abutted, a prompting piece is arranged outside the fixed box, the prompting piece is electrically connected to the electromagnetic button, in order to facilitate the plunger pump body to automatically stop adjusting when it reaches a horizontal angle, so that during the adjustment process of the plunger pump body, the plunger pump body will compress and stretch the two springs respectively due to its own imbalance, so that the pressing piece and the electromagnetic button do not contact each other, when the plunger pump body is adjusted to the horizontal, the pressing piece and the electromagnetic button are located on the same vertical line and abut against each other, at this time the electromagnetic button can send an electrical signal to the motor to turn it off, and activate the flashing light to light up, thereby reminding personnel and automatically turning off the motor, thereby achieving the effect of automatically leveling the plunger pump body.

[0012] Furthermore, the reminder member includes a flashing light, which is fixedly installed on the front side of the fixed box and is electrically connected to the electromagnetic button to remind personnel that the plunger pump body has reached a horizontal angle.

[0013] Furthermore, the number of the springs is two, and the two springs are respectively arranged on both sides of the slider. The arrangement of the two springs can ensure the force balance on both sides of the slider, thereby ensuring that the slider can slide normally to both sides.

[0014] Compared with the prior art, the beneficial effect of the present invention is: by turning on the motor, the driving shaft of the motor drives the first gear to rotate, and the rotation of the second gear can drive the threaded screw to rotate, and then the nut drives the base plate and one end of the plunger pump body to move upward or downward. During this process, the sliding block will slide in the fixed groove along the direction set by the guide rod to avoid the problem of motion interference. At the same time, the L-shaped rod at the other end of the base plate will drive the slide tube to slide in the opposite direction on the guide rod, and the angle of the plunger pump body can be adjusted until the plunger pump body is horizontal, thereby facilitating the connection of the plunger pump body with a matching pipeline.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: during the adjustment of the plunger pump body, the plunger pump body will compress and stretch the two springs respectively due to its own imbalance, so that the pressing piece and the electromagnetic button do not contact each other. When the plunger pump body is adjusted to a horizontal position, the pressing piece and the electromagnetic button are located on the same vertical line and are against each other. At this time, the electromagnetic button can send an electrical signal to the motor and turn it off, and activate the flashing light to light up, thereby reminding personnel and automatically turning off the motor, thereby achieving the effect of automatically leveling the plunger pump body.

DETAILED DESCRIPTION

[0018] 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.

[0019] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] See also Figure 1-4 The present invention provides a technical solution: a conveniently adjustable base for a plunger pump, comprising a mounting base 1, a plunger pump body 2 arranged above the mounting base 1, and a bottom plate 3 fixedly mounted on the bottom of the plunger pump body 2, including: The threaded screw 4 is rotatably mounted in the mounting base 1 along the vertical direction, and a nut 5 is threadedly sleeved on the threaded screw; The guide rod 6 is arranged in a direction corresponding to the threaded screw 4, is rotatably mounted in the mounting base 1, and a slide cylinder 7 is slidably sleeved on the guide rod 6; There are two L-shaped rods 8, which are fixedly mounted on one side of the nut 5 and the slide cylinder 7 respectively, and the other end of the L-shaped rod 8 slides through the mounting base 1 and is movably connected to the bottom of the bottom plate 3; A driving member, disposed in the mounting base 1, for driving the nut 5 and the slide cylinder 7 to move up and down; Two fixed grooves 9 are symmetrically provided at the bottom of the base plate 3, a sliding block 10 is slidably arranged in the fixed groove 9, a mounting seat 11 is fixedly installed at the bottom of the sliding block 10, the L-shaped rod 8 is rotatably arranged in the mounting seat 11, and the driving part includes a motor 13, the motor 13 is fixedly installed on the top wall of the mounting base 1, the driving shaft of the motor 13 is fixedly installed with a first gear 14, and a second gear 15 is fixedly sleeved on the threaded screw 4, and the second gear 15 is meshedly connected with the first gear 14.

[0022] During specific implementation, when in use, if the ground on which the mounting base 1 is installed is uneven, turn on the motor 13 and let the driving shaft of the motor 13 drive the first gear 14 to rotate, so that the first gear 14 drives the second gear 15 to rotate, and the rotation of the second gear 15 can drive the threaded screw 4 to rotate, and then the nut 5 drives the base plate 3 and one end of the plunger pump body 2 to move upward or downward. During this process, the sliding block 10 will slide in the fixed groove 9 to avoid the problem of motion interference. At the same time, the L-shaped rod 8 at the other end of the base plate 3 will drive the slide 7 to slide in the opposite direction on the guide rod 6, and the angle of the plunger pump body 2 can be adjusted until the plunger pump body 2 is level, thereby facilitating the connection of the plunger pump body 2 with a matching pipeline.

[0023] It should be noted here that in order to ensure the accuracy of adjustment of the plunger pump body 2, we can set the diameter of the first gear 14 to be smaller than that of the second gear 15, so that when the first gear 14 rotates, the first gear 14 can drive the second gear 15 to rotate to achieve a deceleration effect, thereby helping to avoid the problem of over-adjustment due to the excessive speed of the second gear 15. It should also be noted that we can also set the motor 13 to be a locking motor. The locking motor usually has a self-locking structure on the drive shaft. Through mechanical principles, the motor output shaft cannot rotate after stopping, thereby preventing the drive shaft of the motor 13 from rotating. Since the locking motor is a prior art and is not a problem that needs to be solved in the background technology of this specification, it will not be explained in detail in this specification.

[0024] See also Figure 1-4 A pin is provided in the mounting seat 11, and one end of the L-shaped rod 8 is rotatably sleeved on the pin. By providing the pin, the L-shaped rod 8 can be reasonably rotated and installed in the mounting seat 11, avoiding the problem of motion interference and also reducing the installation of the operator.

[0025] See also Figure 1-4 A guide rod 12 is inserted into the sliding block 10, and both ends of the guide rod 12 are fixedly installed and connected in the fixing groove 9. The sliding block 10 can only slide along the direction set by the guide rod 12, avoiding the problem of movement deviation of the sliding block 10.

[0026] See also Figure 1-4, also includes a horizontal detection component for detecting the horizontal angle of the plunger pump body 2, the horizontal detection component at least includes a fixed box 16, the fixed box 16 is fixedly installed on the front side of the bottom plate 3, a slider 17 is slidably arranged in the fixed box 16, a spring 18 is installed on the outer side of the slider 17, the other end of the spring 18 is installed in the fixed box 16, a pressing piece 19 is fixedly installed on the top of the slider 17, an electromagnetic button 20 is inlaid on the top wall of the fixed box 16, the electromagnetic button 20 is abutted against the pressing piece 19, a prompting piece is arranged outside the fixed box 16, the prompting piece is electrically connected to the electromagnetic button 20, the prompting piece includes a flashing light 21, the flashing light 21 is fixedly installed on the front side of the fixed box 16, and the flashing light 21 is electrically connected to the electromagnetic button 20.

[0027] In the specific implementation, on the basis of the above implementation, in order to facilitate the piston pump body 2 to stop adjusting when it automatically reaches a horizontal angle, during the adjustment process of the piston pump body 2, the piston pump body 2 will compress and stretch the two springs 18 respectively due to its own imbalance, so that the pressing piece 19 and the electromagnetic button 20 do not contact each other. When the plunger pump body 2 is adjusted to the horizontal, the pressing piece 19 and the electromagnetic button 20 are located on the same vertical line and are against each other. At this time, the electromagnetic button 20 can send an electrical signal to the motor 13 to turn it off, and activate the flashing light 21 to light up, thereby reminding the personnel and automatically turning off the motor 13, thereby achieving the effect of automatically leveling the plunger pump body 2.

[0028] It should be noted here that the electromagnetic button 20 is usually provided with a circuit, a contact block and a spring sheet inside, and the contact block is connected to the spring sheet. When a person presses the contact block, the spring sheet can be connected to the circuit to form a loop, and an electrical signal can be sent to the motor 13 and the flashing light 21 to activate them, thereby achieving the purpose of facilitating the operation of the motor 13 and the flashing light 21. Since the electromagnetic button 20 is a prior art and is not a problem to be solved in the background technology of this specification, it will not be explained in detail in this specification.

[0029] In addition, it should be noted that the shape of the pressing member 19 can be set to be a hemisphere. Since the outer surface of the hemisphere is provided with an arc surface, the electromagnetic button 20 can be pushed normally to connect the power.

[0030] See also Figure 1-4 , the number of springs 18 is two, and the two springs 18 are respectively arranged on both sides of the slider 17. The arrangement of the two springs 18 can ensure the force balance on both sides of the slider 17, thereby ensuring that the slider 17 slides normally to both sides.

[0031] Before use, first connect the plunger pump to an external power source for the electrical appliances on the base, such as the motor 13 and the flashing light 21. Alternatively, install a battery pack on the mounting base 1 in an area that does not hinder the operation of other components, and wrap the battery pack with a protective film. Then, the battery pack is electrically connected to the electrical appliance through a line to supply power to the electrical appliance, thereby ensuring the normal operation of the electrical appliance. Since connecting the electrical appliance to an external power source or installing a battery pack are both existing technologies and are not problems that need to be solved in the background technology of this specification, they will not be described in detail in this specification.

[0032] In addition, it should be noted that when the mounting base 1 is actually used, it is necessary to install fixings on both sides of the mounting base 1, and then thread bolts are inserted into the fixings, the bolts are screwed into the fixings and extended to the inside of the ground, so that the mounting base 1 can be stably installed. The installed mounting base 1 can ensure the stable operation of the plunger pump body 2, and can also cope with the vibration transmitted by the plunger pump body 2, thereby improving the stability of the base.

[0033] Working principle: During use, if the ground on which the mounting base 1 is installed is uneven, turn on the motor 13 and let the driving shaft of the motor 13 drive the first gear 14 to rotate, so that the first gear 14 drives the second gear 15 to rotate. The rotation of the second gear 15 can drive the threaded screw 4 to rotate, and then the nut 5 drives the base plate 3 and one end of the plunger pump body 2 to move upward or downward. During this process, the sliding block 10 will slide in the fixed groove 9 along the direction set by the guide rod 12 to avoid the problem of motion interference. At the same time, the L-shaped rod 8 at the other end of the base plate 3 will drive the slide 7 to slide on the guide rod 6 in the opposite direction, and the angle of the plunger pump body 2 can be adjusted until the plunger pump body 2 is level, thereby facilitating the connection of the plunger pump body 2 with a matching pipeline.

[0034] During the above operation, in order to facilitate the plunger pump body 2 to stop adjusting when it automatically reaches a horizontal angle, during the adjustment of the plunger pump body 2, the plunger pump body 2 will compress and stretch the two springs 18 respectively due to its own imbalance, so that the pressing piece 19 and the electromagnetic button 20 do not contact each other. When the plunger pump body 2 is adjusted to the horizontal, the pressing piece 19 and the electromagnetic button 20 are located on the same vertical line and are against each other. At this time, the electromagnetic button 20 can send an electrical signal to the motor 13 to turn it off, and activate the flashing light 21 to light up, thereby reminding the personnel and automatically turning off the motor 13, thereby achieving the effect of automatically leveling the plunger pump body 2.

[0035] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
