Description

Technical Field

[0001] The invention relates to the technical field of hydraulic solenoid valve pressure monitoring, and in particular to a pressure monitoring device for a hydraulic solenoid valve. Background Art

[0002] Hydraulic solenoid valve is a basic component used to control fluid automation. It is a type of directional control valve used to control the on / off flow of oil or change the direction of oil flow. The mechanical devices in factories are generally controlled by hydraulic cylinders, so hydraulic solenoid valves are used. The one that controls pressure is called a pressure control valve, the one that controls flow is called a flow control valve, and the one that controls on / off and flow direction is called a directional control valve.

[0003] The hydraulic solenoid valve will be subjected to a certain amount of pressure during operation. By monitoring the outlet and inlet pressure of the hydraulic solenoid valve, it is possible to promptly determine whether the hydraulic solenoid valve is operating normally. If the pressure is found to be too high or too low, timely adjustments and repairs should be made. When monitoring the inlet and outlet pressures of the hydraulic solenoid valve, the current common method is to install a pressure gauge on the surface of the inlet and outlet pipes of the hydraulic solenoid valve, so that the staff can infer the inlet and outlet pressures of the hydraulic solenoid valve at this time based on the value displayed on the pressure gauge, and can flexibly adjust the pressure.

[0004] However, in the prior art, when installing the pressure gauge, it is necessary to wrap multiple layers of sealing tape on the surface of the connection end to ensure that there is no oil leakage during use. However, in the process of wrapping the sealing tape, unskilled workers cannot accurately grasp the number and length of the wrapped sealing tape, which results in the workers repeatedly adjusting the number and length of the sealing tape to be wrapped on the surface of the connection end, which consumes a lot of time to seal and install the pressure gauge. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings in the prior art and to provide a pressure monitoring device for a hydraulic solenoid valve.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A pressure monitoring device for a hydraulic solenoid valve comprises a pressure gauge and a mounting plate, wherein the pressure gauge is mounted at a central position inside the mounting plate, a connecting end is arranged at the bottom end of the pressure gauge, a mounting mechanism for assisting the connecting end to be mounted on the inlet and outlet of the hydraulic solenoid valve is arranged at the bottom of the mounting plate, two rotating plates are rotatably mounted on the top of the mounting plate, a cleaning mechanism for cleaning the surface of the pressure gauge is arranged inside the two rotating plates, and a shock absorbing mechanism for buffering the vibration borne by the pressure gauge is installed at the bottom of the mounting plate.

[0008] Optionally, the mounting mechanism includes a first fixed plate installed at the bottom of the mounting plate, two sliding grooves are provided at the bottom of the first fixed plate, sliding blocks are slidably installed inside the two sliding grooves, and clamps are installed at the bottom ends of the two sliding blocks.

[0009] Optionally, two second fixing plates are installed at the bottom of the first fixing plate, and screws are threadedly installed inside the two second fixing plates. The ends of the two screws close to the connecting ends are rotatably connected to the clamping plates close to them.

[0010] Optionally, an airbag is mounted on the surface of the connection end, and an inflation port for inflating the interior of the airbag is mounted on an outer wall of one side of the mounting plate, and a one-way valve is preset inside the inflation port.

[0011] Optionally, the cleaning mechanism includes circular through grooves formed inside the two rotating plates, the diameters of the two circular through grooves are both larger than the diameter of the pressure gauge, and the inner walls of the two circular through grooves are both provided with circular grooves.

[0012] Optionally, two electric sliders are installed inside the two circular grooves, and a mounting seat is installed on the end of the two electric sliders away from the circular groove, a third fixing plate is installed on the outer wall of one side of the two mounting seats, and a first cleaning pad is installed on the outer wall of the two third fixing plates close to the pressure gauge.

[0013] Optionally, a rotating rod is rotatably mounted inside the two mounting seats, and a second cleaning pad is mounted on the outer wall of the two rotating rods on one side close to the pressure gauge.

[0014] Optionally, the shock absorbing mechanism includes two rectangular plates arranged at the bottom of the mounting plate, the bottom of the mounting seat is connected to the tops of the two rectangular plates respectively through two groups of springs, and damping rods are installed inside the two groups of springs.

[0015] Optionally, buffer pads are installed at the bottom of the two rectangular plates, and the two buffer pads are made of rubber material.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the present invention, after the connecting end is inserted into the connecting port or the interior of the three-way connector by means of the airbag arranged in the installation mechanism, the gas is filled into the interior of the airbag through the inflation port with the help of an external preset inflation device or tool, so that the airbag is located inside the connecting port or the three-way connector and inflated and expanded, thereby achieving the same effect as sealing the connecting parts by winding multiple layers of sealing tape in the prior art, avoiding the leakage of hydraulic oil, and the entire sealing process of the connecting part of the connecting end is relatively convenient and quick, which greatly improves the installation efficiency of the pressure gauge and will not be affected by the proficiency of the staff.

[0018] 2. In the invention, after the pressure gauge is connected to the connecting port or the three-way connector, the two buffer pads can abut against the outer wall of the inlet and outlet pipes of the hydraulic solenoid valve. When the oil inside the inlet and outlet pipes of the subsequent hydraulic solenoid valve flows and causes the inlet and outlet pipes to vibrate, the vibration can be buffered and released with the help of the cooperation of the spring and the damping rod to prevent the vibration from being directly transmitted to the inside of the pressure gauge, thereby achieving the effect of vibration buffering and shock absorbing, ensuring that the pressure gauge is not affected by the vibration of the inlet and outlet pipes when in use, and improving the service life of the pressure gauge.

[0019] 3. In the invention, during normal use of the pressure gauge, the two rotating plates are in a horizontal state after being rotated downward, and the corresponding rotating rods inside the two mounting seats are rotated to a state flush with the third fixed plate. The positions of the two electric sliders inside the circular groove 5 are controlled to be adjusted, and the two rotating plates are controlled to continue to rotate downward in an inclined state, so that the ends of the corresponding two rotating rods away from the mounting seats are in contact with the outer wall of the inlet and outlet pipes or the outer wall of the three-way connector, thereby improving the stability of the pressure gauge during use during the continuous change of the internal pressure of the inlet and outlet pipes, and avoiding the problem that the connection ends are subjected to greater pressure and are easily damaged.

[0020] 4. In the present invention, when it is necessary to clean and remove dust and other impurities attached to the surface of the pressure gauge during use, the two rotating plates are controlled to rotate upward to a vertical state. At this time, the two corresponding third fixed plates are located on the circular outer wall surface of the pressure gauge, so that the first cleaning pads arranged on the outer walls of the two third fixed plates abut against the circular outer wall of the pressure gauge. Then, the two rotating rods are controlled to rotate inside the mounting seat toward the direction close to the pressure gauge, driving the second cleaning pad on the outer wall of one side of the rotating rod to abut against the horizontal outer walls on both sides of the pressure gauge. As the two electric sliders drive the first cleaning pad and the second cleaning pad to perform a comprehensive cleaning treatment on the outer wall of the pressure gauge, there is no need to manually clean and remove dust and other impurities attached to the surface of the pressure gauge, which is convenient for the subsequent long-term use of the pressure gauge and the accurate monitoring of the pressure of the hydraulic solenoid valve.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0031] Reference Figure 1-Figure 7 A pressure monitoring device for a hydraulic solenoid valve includes a pressure gauge 1 and a mounting plate 2. The pressure gauge 1 is mounted in the center of the mounting plate 2. A connecting end 16 is provided at the bottom of the pressure gauge 1. A mounting mechanism for assisting the connecting end 16 to be mounted at the inlet and outlet of the hydraulic solenoid valve is provided at the bottom of the mounting plate 2. Two rotating plates 3 are rotatably mounted on the top of the mounting plate 2. A cleaning mechanism for cleaning the surface of the pressure gauge 1 is provided inside the two rotating plates 3. A shock absorbing mechanism for buffering the vibrations borne by the pressure gauge 1 is installed at the bottom of the mounting plate 2. In actual use, two first driving devices are preset at the top of the mounting plate 2. The output ends of the two first driving devices are respectively connected to the rotating parts of the two rotating plates 3, so that the two rotating plates 3 can be driven to rotate and adjust at the top of the mounting plate 2.

[0032] As a technical optimization solution of the present invention, the mounting mechanism includes a first fixed plate 8 mounted on the bottom of the mounting plate 2, and two slide grooves 17 are provided at the bottom of the first fixed plate 8. Sliding blocks 20 are slidably mounted inside the two slide grooves 17, and clamping plates 10 are mounted at the bottom ends of the two sliding blocks 20. The sliding blocks 20 are arranged to move back and forth inside the slide grooves 17, and have a guiding effect on the moving track of the clamping plates 10, thereby preventing deviation of the movement of the clamping plates 10.

[0033] As a technical optimization solution of the present invention, two second fixing plates 19 are installed at the bottom of the first fixing plate 8, and the interiors of the two second fixing plates 19 are both threadedly installed with screw rods 9, and the ends of the two screw rods 9 close to the connection ends 16 are rotatably connected to the clamping plates 10 close to them. By twisting the two screw rods 9, the two screw rods 9 are driven to move in the direction of approaching, and the two clamping plates 10 are pushed in the direction of approaching, so that the two clamping plates 10 can be tightly abutted against the outer wall of the preset connection port of the inlet and outlet pipes of the hydraulic solenoid valve or the three-way connector, ensuring that the pressure gauge 1 can be stably connected and fixed to the connection port or the three-way connector.

[0034] As a technical optimization solution of the present invention, the surface of the connection end 16 is provided with an airbag 11, and an air charging port 18 for inflating the inside of the airbag 11 is installed on the outer wall of one side of the mounting plate 2, and a one-way valve is preset inside the air charging port 18. After the connection end 16 is inserted into the inside of the connection port or the three-way connector, the gas can be charged into the inside of the airbag 11 through the air charging port 18 through the preset air charging device or tool, so that the airbag 11 is located inside the connection port or the three-way connector and inflated and expanded, thereby improving the sealing of the connection between the connection end 16 and the connection port or the three-way connector, and avoiding the leakage of hydraulic oil.

[0035] As a technical optimization solution of the present invention, the cleaning mechanism includes circular through grooves 4 opened inside the two rotating plates 3, the diameters of the two circular through grooves 4 are both larger than the diameter of the pressure gauge 1, and the inner walls of the two circular through grooves 4 are both provided with circular grooves 5.

[0036] As a technical optimization solution of the present invention, two electric sliders 21 are installed inside the two circular grooves 5, and the ends of the two electric sliders 21 away from the circular grooves 5 are installed with mounting seats 22, and the outer walls of one side of the two mounting seats 22 are installed with third fixing plates 6, and the outer walls of the two third fixing plates 6 close to the pressure gauge 1 are installed with first cleaning pads 23. Two arc linear motors are preset inside the two circular grooves 5, and the two arc linear motors can drive the two electric sliders 21 to move and adjust in a semicircular trajectory inside the circular grooves 5.

[0037] As a technical optimization solution of the present invention, a rotating rod 7 is rotatably mounted inside the two mounting seats 22, and a second cleaning pad 24 is mounted on the outer wall of the two rotating rods 7 close to the pressure gauge 1. A second driving device is preset on the outer wall of one side of the two mounting seats 22, and the output ends of the two second driving devices are respectively connected to the rotating parts of the two rotating rods 7, so as to drive the two rotating rods 7 to rotate and adjust.

[0038] As a technical optimization solution of the present invention, the shock absorbing mechanism includes two rectangular plates 14 arranged at the bottom of the mounting plate 2, and the bottom of the mounting seat 22 is respectively connected to the top of the two rectangular plates 14 through two groups of springs 12, and damping rods 13 are installed inside the two groups of springs 12.

[0039] As a technical optimization solution of the present invention, a buffer pad 15 is installed at the bottom of the two rectangular plates 14, and the two buffer pads 15 are made of rubber material. After the pressure gauge 1 is connected to the connection port or the three-way connector, the two buffer pads 15 can abut against the outer wall of the inlet and outlet pipes of the hydraulic solenoid valve. When the inlet and outlet pipes vibrate, the vibration can be buffered and released with the help of the spring 12 and the damping rod 13 to prevent the vibration from being directly transmitted to the inside of the pressure gauge 1, thereby achieving the effect of vibration buffering and shock reduction, ensuring that the pressure gauge 1 is not affected by the vibration of the inlet and outlet pipes when in use, and improving the service life of the pressure gauge 1.

[0040] In the present invention, when the user uses the device, the pressure gauge 1 is installed on the surface of the inlet and outlet pipes of the hydraulic solenoid valve that needs to monitor the pressure, and the connecting end 16 can be directly inserted into the preset connecting port on the surface of the inlet and outlet pipes, or into the inside of the three-way connector added to facilitate the installation of the pressure gauge 1. Then, the two screws 9 are respectively screwed to drive the two clamping plates 10 to tightly abut against the surface of the connecting port or the three-way connector, thereby achieving the effect of quickly and stably installing the pressure gauge 1. There is no need to drive the pressure gauge 1 itself to rotate for installation, which reduces the vibration and shaking of the pressure gauge 1 during the installation process, so that the pressure gauge 1 can enter the working state in time after installation.

[0041] At the same time, the traditional pressure gauge 1 needs to wrap multiple layers of sealing tape on the surface of the connecting end 16 during the installation process to ensure that there will be no oil leakage during use. However, in the process of winding the sealing tape, unskilled staff cannot accurately grasp the number and length of the wrapped sealing tape layers, which causes the staff to repeatedly adjust the number and length of the sealing tape layers that need to be wrapped on the surface of the connecting end 16, which consumes a lot of time to seal and install the pressure gauge 1. In the present invention, after the connecting end 16 is inserted into the interior of the connecting port or the three-way connector, with the help of an external preset inflation device or tool, the gas is filled into the interior of the airbag 11 through the inflation port 18, so that the airbag 11 is located in the connecting port or the three-way connector and inflated and expanded, thereby achieving the same effect as the prior art of sealing the connecting parts by winding multiple layers of sealing tape, avoiding the occurrence of hydraulic oil leakage, and the entire sealing process of the connecting part of the connecting end 16 is relatively convenient and quick, which greatly improves the installation efficiency of the pressure gauge 1 and will not be affected by the proficiency of the staff.

[0042] Furthermore, after the pressure gauge 1 is connected to the connecting port or the three-way connector, the two buffer pads 15 can abut against the outer wall of the inlet and outlet pipes of the hydraulic solenoid valve. When the oil inside the inlet and outlet pipes of the subsequent hydraulic solenoid valve flows and causes the inlet and outlet pipes to vibrate, the vibration can be buffered and released with the help of the cooperation of the spring 12 and the damping rod 13 to prevent the vibration from being directly transmitted to the inside of the pressure gauge 1, thereby achieving the effect of vibration buffering and shock absorbing, ensuring that the pressure gauge 1 is not affected by the vibration of the inlet and outlet pipes when in use, thereby increasing the service life of the pressure gauge 1.

[0043] Moreover, if Figure 1 As shown, during normal use of the pressure gauge 1, the two rotating plates 3 are in a horizontal state after being rotated downward, and the rotating rods 7 inside the corresponding two mounting seats 22 are rotated to be flush with the third fixed plate 6, and Figure 1 On the basis of this, the positions of the two electric sliders 21 inside the circular groove 5 are controlled to be adjusted, and the two rotating plates 3 are controlled to continue to rotate downward in an inclined state, so that the ends of the corresponding two rotating rods 7 away from the mounting seat 22 abut against the outer wall of the inlet and outlet pipes or the outer wall of the three-way connector, thereby improving the stability of the pressure gauge 1 during use during the process of constantly changing internal pressure of the inlet and outlet pipes, and avoiding the problem that the connecting end 16 is subjected to greater pressure and is easily damaged.

[0044] During the use of the pressure gauge 1, dust and other impurities in the working environment will inevitably adhere to its surface. When it is necessary to clean and remove the dust and other impurities attached to the surface of the pressure gauge 1, such as Figure 2As shown, the two rotating plates 3 are controlled to rotate upward to a vertical state. At this time, the two corresponding third fixed plates 6 are located on the circular outer wall surface of the pressure gauge 1, so that the first cleaning pads 23 set on the outer walls of the two third fixed plates 6 abut against the circular outer wall of the pressure gauge 1, and then the two rotating rods 7 are controlled to rotate inside the mounting seat 22 toward the direction close to the pressure gauge 1, driving the second cleaning pad 24 set on the outer wall of one side of the rotating rod 7 to abut against the horizontal outer walls on both sides of the pressure gauge 1, and as the two electric sliders 21 move in a semicircular arc inside the circular groove 5, the first cleaning pad 23 and the second cleaning pad 24 are driven to perform a comprehensive cleaning treatment on the outer wall of the pressure gauge 1, without manual cleaning and removal of dust and other impurities attached to the surface of the pressure gauge 1, which is convenient for the subsequent long-term use of the pressure gauge 1 and the accurate monitoring of the pressure of the hydraulic solenoid valve.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described.
