Description

Technical Field

[0001] This utility model relates to the field of interlocking integrated machine technology, and in particular to a multi-functional quantitative loading and unloading vehicle safety interlocking integrated machine. Background Technology

[0002] Chemical loading and unloading operations involve hazardous chemicals. Chemical loading and unloading vehicles are mainly used for the transportation of various oils and chemical liquids in the petrochemical industry, namely, the transportation of various gasoline, diesel, liquefied petroleum gas, liquefied natural gas and other liquid resins. Therefore, safety control is necessary, which requires the use of an interlocking integrated machine.

[0003] In the existing interlocking integrated machine, it is impossible to add chemicals quantitatively during the chemical loading and unloading process. Manual observation is required to prevent chemical spills.

[0004] For example, in the prior art, the patent with authorization announcement number CN221720493U discloses a multi-functional quantitative loading and unloading vehicle safety interlocking integrated machine. The device eliminates static electricity on the workers' bodies through an electrostatic discharge ball, uses an explosion-proof quantitative loading controller to accurately measure the medium loaded and unloaded from chemical trucks and provide electrostatic protection, and manages the use of tank truck keys through a key manager to avoid damage to oil depot equipment caused by improper operation, so as to improve the strict control of the operating procedures of the operators. In an emergency, the explosion-proof emergency stop button can quickly stop all operations, thereby avoiding possible safety accidents.

[0005] This device achieves quantitative addition of chemicals by installing a flow control panel. However, when the loading volume of the chemical transport vehicle is unclear, or when there are remaining chemicals in the transport tank of the chemical transport vehicle, the quantity loaded on the transport vehicle cannot be determined, which affects the practicality of the device. Therefore, a multi-functional quantitative loading and unloading safety interlocking integrated machine is designed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a multi-functional quantitative loading and unloading vehicle safety interlocking integrated machine.

[0007] The technical problem to be solved by this utility model is to provide a multi-functional quantitative loading and unloading vehicle safety interlocking integrated machine, which solves the problem in the prior art that when the loading volume of chemical transport vehicles is unclear, or when there are residual chemicals in the transport tank of chemical transport vehicles, the quantity loaded in the transport vehicle cannot be determined, and thus quantitative filling of the transport vehicle cannot be achieved.

[0008] This utility model provides a multi-functional quantitative loading and unloading vehicle safety interlocking integrated machine, including a machine body, an oil pump, a spiral tube, a connector, a gripper rod, and a liquid outlet pipe. The oil pump is installed on the left side of the machine body. The output end of the oil pump is connected to the spiral tube. The end of the spiral tube is connected to the connector. A gripper rod is fixedly installed on one side of the connector. The bottom of the connector is threadedly connected to the liquid outlet pipe. A flow meter is installed on the top of the inner side of the liquid outlet pipe. A solenoid valve is installed on the upper inner side of the liquid outlet pipe. A control panel is installed on the outer surface of the machine body.

[0009] The outlet pipe includes a rubber column, a hemispherical groove, a through hole, a spring, a top plate, a connecting rod, and a float. The rubber column is fixedly installed on the lower inner side of the outlet pipe. A hemispherical groove is opened in the center of the bottom surface of the rubber column. A through hole is opened in the center of the top of the rubber column. A spring is fixedly installed in the center of the upper surface of the rubber column. A top plate is fixedly installed on the top of the spring. A float is connected to the center of the bottom surface of the top plate through a connecting rod.

[0010] Preferably, the control panel is electrically connected to the flow meter and the solenoid valve.

[0011] Preferably, the diameter of the hemispherical groove is equal to the diameter of the float.

[0012] Preferably, the diameter of the connecting rod is smaller than the diameter of the through hole, the connecting rod passes through the through hole, and the diameter of the float is larger than the diameter of the through hole.

[0013] Preferably, when the spring is in its naturally extended state, the upper surface of the float is at a lower level than the bottom of the rubber column.

[0014] Preferably, the top plate is made of copper material with good conductivity, a stationary contact plate is installed on the upper inner side of the liquid outlet pipe, and the top plate, stationary contact plate, solenoid valve and power supply of the machine body are connected in series by wires.

[0015] Preferably, when the float is embedded in the hemispherical groove, the top plate is in close contact with the bottom surface of the stationary contact plate.

[0016] Preferably, an electrostatic discharge ball is installed on the body, and an electrostatic grounding clamp is installed on the right side of the body.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] 1. This utility model is equipped with a flow meter and a solenoid valve. When the transport volume of the chemical transport tank is known, the volume of the outflow pipe can be set through the control panel. When adding chemicals into the transport vehicle, the flow meter detects the amount of chemicals flowing out of the outflow pipe in real time, so as to achieve the effect of quantitative loading. When the flow meter discharges the specified amount of chemicals, the control panel controls the solenoid valve to close, so as to achieve the effect of sealing the outflow pipe and preventing the chemicals from flowing out again.

[0019] 2. This utility model features a liquid outlet pipe. When the transport volume of the chemical product transport tank is unclear, the outlet pipe is inserted into the transport tank to add chemicals. When the liquid level of the chemical product in the transport tank is higher than the horizontal height of the float, the float floats on the surface of the chemical product and moves upward until it is embedded in the hemispherical groove, blocking the through hole. This prevents the chemical product from being discharged from the outlet pipe, thus preventing the chemical product from overflowing from the transport tank. At this time, the top plate is attached to the bottom surface of the stationary contact plate, and the circuit between the power supply of the machine and the solenoid valve is connected. The solenoid valve is energized and closed, thus sealing the outlet pipe and preventing the chemical product from being discharged from the outlet pipe again.

[0020] 3. This utility model is equipped with an electrostatic discharge ball, which can eliminate static electricity on the staff when they touch it. By being equipped with an electrostatic grounding clamp, the electrostatic grounding clamp can be connected to the vehicle's electrostatic plate to avoid sparks caused by static electricity, thereby reducing the occurrence of accidents.

[0028] Example:

[0029] like Figures 1-4 As shown, an embodiment of this utility model provides a multi-functional quantitative loading and unloading vehicle safety interlocking integrated machine, including a machine body 1, an oil pump 2, a spiral tube 3, a connector 4, a gripper 5, and a liquid outlet pipe 6. The oil pump 2 is installed on the left side of the machine body 1. The output end of the oil pump 2 is connected to the spiral tube 3. The end of the spiral tube 3 is connected to the connector 4. A gripper 5 is fixedly installed on one side of the connector 4. The bottom of the connector 4 is threadedly connected to the liquid outlet pipe 6. A flow meter 7 is installed on the top of the inner side of the liquid outlet pipe 6. A solenoid valve 8 is installed on the upper inner side of the liquid outlet pipe 6. A control panel 101 is installed on the outer surface of the machine body 1.

[0030] The liquid outlet pipe 6 includes a rubber column 601, a hemispherical groove 602, a through hole 603, a spring 604, a top plate 605, a connecting rod 606, and a float 607. The rubber column 601 is fixedly installed on the lower inner side of the liquid outlet pipe 6. The hemispherical groove 602 is opened in the center of the bottom surface of the rubber column 601. The through hole 603 is opened in the center of the top of the rubber column 601. The spring 604 is fixedly installed in the center of the upper surface of the rubber column 601. The top plate 605 is fixedly installed on the top of the spring 604. The float 607 is connected to the center of the bottom surface of the top plate 605 through the connecting rod 606.

[0031] With the flow meter 7 and solenoid valve 8 installed, when the transport volume of the chemical transport tank is known, the volume of the outflow pipe 6 can be set through the control panel 101. When adding chemicals into the transport vehicle, the flow meter 7 detects the amount of chemicals flowing out of the outflow pipe 6 in real time, achieving the effect of quantitative loading. When the flow meter 7 discharges the specified amount of chemicals, the control panel 101 controls the solenoid valve 8 to close, achieving the effect of sealing the outflow pipe 6 and preventing the chemicals from flowing out again.

[0032] With the outlet pipe 6 installed, when the transport volume of the chemical transport tank is unclear, the outlet pipe 6 is inserted into the transport tank to add chemicals. When the liquid level of the chemical in the transport tank is higher than the horizontal height of the float 607, the float 607 floats on the liquid surface of the chemical and moves upward until the float 607 is embedded in the hemispherical groove 602, blocking the through hole 603. The chemical is no longer discharged from the outlet pipe, thus preventing the chemical from overflowing from the transport tank. At this time, the top plate 605 is attached to the bottom surface of the stationary contact plate 9, and the circuit between the power supply of the machine body 1 and the solenoid valve 8 is connected. The solenoid valve 8 is energized and closed, thus sealing the outlet pipe 6 and preventing the chemical from being discharged from the outlet pipe 6 again.

[0033] In this embodiment, the control panel 101 is electrically connected to the flow meter 7 and the solenoid valve 8.

[0034] In this embodiment, the diameter of the hemispherical groove 602 is equal to the diameter of the float 607, which facilitates the float being embedded in the hemispherical groove 602.

[0035] In this embodiment, the diameter of the connecting rod 606 is smaller than the diameter of the through hole 603, and the connecting rod 606 passes through the through hole 603. The diameter of the float 607 is larger than the diameter of the through hole 603, so that there is a gap between the connecting rod 606 and the through hole 603, which facilitates the flow of chemicals from the gap between the through hole 603 and the connecting rod 606.

[0036] In this embodiment, when the spring 604 is in its naturally extended state, the upper surface of the float 607 is at a lower level than the bottom of the rubber post 601. At this time, the float 607 will not block the through hole 603.

[0037] In this embodiment, the top plate 605 is made of copper material with good conductivity, and a stationary contact plate 9 is installed on the upper inner side of the liquid outlet pipe 6. The power supply of the top plate 605, the stationary contact plate 9, the solenoid valve 8 and the body 1 is connected in series through the wire 10.

[0038] In this embodiment, when the float 607 is embedded in the hemispherical groove 602, the top plate 605 is in close contact with the bottom surface of the stationary contact plate 9, thus connecting the circuit. At this time, the solenoid valve 8 is closed.

[0039] In this embodiment, an electrostatic discharge ball 102 is installed on the body 1, and an electrostatic grounding clamp is installed on the right side of the body 1.

[0040] By installing an electrostatic discharge ball 102, static electricity on the worker's body can be eliminated when the worker touches it. By installing an electrostatic grounding clamp, the electrostatic grounding clamp can be connected to the vehicle's electrostatic plate to avoid sparks caused by static electricity, thereby reducing the occurrence of accidents.

[0041] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
