Description

Technical Field

[0001] This invention relates to the field of automotive electrical technology, and in particular to a switching circuit and method for switching between driving and driller control of vehicle-mounted well workover equipment. Background Technology

[0002] Vehicle-mounted well workover equipment is a common type of well workover operation equipment, typically a workover rig. Currently, the driller control system of vehicle-mounted well workover rigs generally uses a single circuit control. This means that after the main power switch of the vehicle is turned on, the vehicle starts, the chassis electrical equipment controlling the driver operates normally, and the driller control equipment is simultaneously powered on and operates normally. At this time, the vehicle-mounted well workover equipment can perform both driving and well workover operations simultaneously.

[0003] During this operation, the chassis driving control and the driller's operation control are always working simultaneously. After the vehicle starts, considering that the chassis driver's cab is unattended while the worker is operating it in the driller's control room, there is a certain safety hazard. In severe cases, it may lead to personal injury or equipment damage. Therefore, at least two oilfield workers are required to cooperate in the operation. It cannot be operated by a single person. Moreover, during the cooperation operation, the staff in the driller's control room may not be able to know the working status of the chassis in time, which may affect the normal well repair operation, making it inconvenient for safe operation and resulting in low work efficiency. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention provides a driving and drilling control switching circuit and method for vehicle-mounted well workover equipment, which separates vehicle driving and well workover operations, enabling one-button switching between the two working modes of vehicle driving and well workover operations. This facilitates single-person operation and improves safety and work efficiency.

[0005] In one aspect, this disclosure provides a driving and driller control switching circuit for vehicle-mounted well workover equipment.

[0006] A driving and driller control switching circuit for a vehicle-mounted well workover equipment includes a switching switch, which is connected to a chassis control circuit and a driller control circuit, and is used to control the signal switching between the chassis control circuit and the driller control circuit.

[0007] The switching switch is connected to the power module and its signal acquisition module. The power module includes a generator, a gearbox, and a fuel tank. The generator is connected to the switching switch and supplies power to the chassis control circuit or the driller control circuit depending on the switching switch position. The signal acquisition module is used to acquire gearbox oil temperature signals, gearbox oil pressure signals, and fuel quantity signals. Depending on the switching switch position, it is connected to the instrument display module of the chassis control circuit or the instrument display module of the driller control circuit.

[0008] In a further technical solution, the chassis control circuit is used to control the normal operation of the chassis electrical system to achieve vehicle driving; the driller control circuit is used to control the normal operation of the driller control system to achieve well workover operations.

[0009] In a further technical solution, one end of the switching switch is connected to the signal input line, and the other end is connected to the signal output line;

[0010] The signal input lines include transmission oil pressure signal, transmission oil temperature signal, fuel quantity signal, and generator signal; the signal output lines are divided into two paths, one is the normally closed contact of the switch, and the signal output line is connected to the chassis control circuit and its instrument display module, and the other is the normally open contact of the switch, and the signal output line is connected to the driller control circuit and its instrument display module.

[0011] A further technical solution is that the switching switch includes two switching positions: one position is for connecting to the main electrical system, which includes the chassis control circuit and its instrument display module; the other position is for connecting to the rear operating electrical system, which includes the driller control circuit and its instrument display module.

[0012] In a further technical solution, the instrument display module of the chassis control circuit is a combined instrument panel, and the instrument display module of the driller control circuit is a rear operation instrument panel.

[0013] In a further technical solution, the switching switch includes multiple contacts, which are connected to the main electrical system or the subsequent operating electrical system at different switching positions.

[0014] A further technical solution involves connecting the first and second contacts, the fifth and sixth contacts, the thirteenth and fourteenth contacts, and the ninth and tenth contacts inside the switch when the switch is in position 0. The second, sixth, fourteenth, and tenth contacts are connected to the generator signal, the transmission oil pressure signal, the fuel quantity signal, and the transmission oil temperature signal, respectively. The first, fifth, thirteenth, and ninth contacts are connected to the chassis control circuit, the transmission oil pressure gauge on the instrument cluster, the fuel quantity gauge on the instrument cluster, and the transmission oil temperature gauge on the instrument cluster, respectively.

[0015] A further technical solution is that when the switch is in position 1, the second and third contacts are connected, and the third contact is a normally open position of the switch. When the switch is turned on, the second contact of the switch is connected to the third contact through the fourth contact, and the third contact is connected to the driller's control circuit.

[0016] A further technical solution is that when the switch is in position 1, the sixth and seventh contacts, the fourteenth and fifteenth contacts, and the tenth and eleventh contacts are connected. The seventh, fifteenth, and eleventh contacts are respectively connected to the transmission oil pressure gauge, the fuel gauge, and the transmission oil temperature gauge on the rear operating instrument.

[0017] Secondly, this disclosure provides a method for switching between driving and driller control of vehicle-mounted well workover equipment, implemented based on the driving and driller control switching circuit of the vehicle-mounted well workover equipment, including the following steps:

[0018] Turn on the main power switch to power on the vehicle.

[0019] When the vehicle is started in the START position, the chassis control circuit is powered on, the chassis electrical equipment operates normally, the instrument display module of the chassis control circuit displays the status information of the chassis control circuit, and the vehicle is driven normally based on the chassis control circuit.

[0020] When the vehicle is parked at idle speed, turning on the switch de-energizes the chassis control circuit, stops the chassis electrical equipment from operating, energizes the driller control circuit, and enables the driller electrical equipment to operate normally. The instrument display module of the driller electrical equipment displays the status information of the driller control circuit, and the well workover operation is controlled based on the driller control circuit.

[0021] The above one or more technical solutions have the following beneficial effects:

[0022] 1. This invention provides a driving and drilling control switching circuit and switching method for vehicle-mounted well workover equipment, which separates vehicle driving and well workover operations, and realizes the function of quickly switching between the two working modes of vehicle driving and well workover operations with one key, which is convenient for single-person operation.

[0023] 2. This invention uses a switching switch to achieve circuit switching. When the switching switch is not turned on, the chassis electrical equipment operates normally with power. When the switching switch is turned on, the chassis electrical equipment is de-energized and stops working, while the driller's electrical equipment is energized and begins working. This allows the chassis control circuit controlling driving operations and the driller control circuit controlling well workover operations to operate independently without interference. This enables safe operation by a single person, improves operational safety, reduces the time wasted in multi-person operations, and improves work efficiency. At the same time, under independent and safe operation conditions, the damage rate and depreciation rate of equipment are reduced, greatly extending the service life of the oilfield well workover rig.

[0029] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Example 1

[0032] This embodiment provides a driving and driller control switching circuit for vehicle-mounted well workover equipment, such as... Figure 1 and Figure 2 As shown, it includes a switch (also known as a changeover switch, in...) Figure 2 The switch (marked as a changeover switch) is connected to the chassis control circuit and the driller control circuit, and is used to control the signal switching between the chassis control circuit and the driller control circuit.

[0033] The switching switch is connected to the power module and its signal acquisition module. The power module includes a generator and a gearbox (also known as a transmission). Figure 1 and Figure 2 The components are labeled as transmission and fuel tank. The generator is connected to the switch and supplies power to the chassis control circuit or the driller control circuit depending on the switch position. The signal acquisition module is used to acquire transmission oil temperature signal, transmission oil pressure signal and fuel quantity signal, and is connected to the instrument display module of the chassis control circuit or the instrument display module of the driller control circuit depending on the switch position.

[0034] The chassis control circuit is used to control the normal operation of the chassis electrical system, that is, to control the vehicle's movement; the driller control circuit is used to control the normal operation of the driller control system, that is, to control the well workover operation.

[0035] This embodiment utilizes a switch to switch circuits, achieving independent power supply for the driller's control system and the chassis control system. Simultaneously, the collected signals such as fuel level, transmission oil pressure, and transmission oil temperature from the power module are switched via the switch, enabling separate and independent display of the chassis electrical system and the driller's electrical system. This divides them into two independent electrical systems, allowing for one-button switching between two working modes: vehicle driving and well workover operations.

[0036] The switching switch is as follows Figure 1 As shown, one end of the switch is connected to the signal input line, and the other end is connected to the signal output line. The signal input line includes signals such as transmission oil pressure, transmission oil temperature, fuel quantity, and alternator B+ signal. The signal output line is divided into two paths: one is the normally closed contact of the switch, connecting to the instrument display module of the chassis control circuit (i.e., the chassis instrument cluster); the other is the normally open contact of the switch, connecting to the instrument display module of the driller's control circuit (i.e., the rear control instrument). The switching between the normally open and normally closed contacts is controlled by manipulating the switch; when the switch is closed, the normally closed contact is closed, and the normally open contact is open. During normal startup, the chassis electrical equipment is powered, while the driller's control electrical equipment is de-energized; when the switch is opened, the normally closed contact opens, and the normally open contact closes, de-energizing the chassis electrical equipment and energizing the driller's control electrical equipment.

[0037] In existing technologies, the chassis control system and the driller's control system always operate simultaneously. That is, when the vehicle starts and the operator is working at the driller's control console, the chassis cab is unattended, posing certain safety risks. Firstly, the operator's inability to promptly ascertain the chassis's operational status may interfere with normal well workover operations. Secondly, if someone enters the cab alone during well workover operations, it poses a safety hazard, potentially leading to injury or death of personnel or equipment. This embodiment improves upon existing technology with its switching circuit, separating vehicle driving and well workover operations. It enables one-button switching between these two modes, enhancing safety and work efficiency.

[0038] The aforementioned chassis control circuit, serving as the main electrical system, is powered by a generator signal connected to the switch. The aforementioned driller control circuit, serving as the rear control panel electrical system, is also powered by a generator signal connected to the switch. The switch allows for signal switching between the chassis control circuit and the driller control circuit; signals from these two circuits cannot be used simultaneously. The switch has two positions: one for connecting to the main electrical system (chassis control circuit and its instrument display module), and the other for connecting to the rear control electrical system (driller control circuit and its instrument display module). In this embodiment, the instrument display module of the chassis control circuit is a combination instrument panel, similar to those found in existing vehicles; the instrument display module of the driller control circuit is a rear control instrument panel.

[0039] like Figure 1 As shown, the wires used to connect the signal and the switch are marked with wire numbers. For example, B1+W 2.5 means: wire number is B1+, color is white, and wire diameter is 2.5mm. 2 The meaning of 18A W 1 is: the wire number is 18A, the color is white, and the wire diameter is 1mm. 2The changeover switch contains multiple contacts, which are connected to the main electrical system or the subsequent operating electrical system in different switching positions. Specifically, when the changeover switch is in position 0, the first contact 1 and the second contact 2, the fifth contact 5 and the sixth contact 6, the thirteenth contact 13 and the fourteenth contact 14, and the ninth contact 9 and the tenth contact 10 inside the changeover switch are connected. Among them, the second contact 2, the sixth contact 6, the fourteenth contact 14, and the tenth contact 10 are respectively connected to the generator signal, the collected transmission oil pressure signal, the fuel quantity signal, and the transmission oil temperature signal. The first contact 1, the fifth contact 5, the thirteenth contact 13, and the ninth contact 9 are respectively connected to the chassis control circuit and the combination instrument. The transmission oil pressure gauge, fuel gauge, and transmission oil temperature gauge on the instrument cluster are displayed. At this time, the chassis control system can operate normally, but the driller's control electrical equipment is de-energized. When the selector switch is in position 1, the second contact 2 and the third contact 3 are connected. The third contact 3 is a normally open position of the selector switch. When the selector switch is opened, the second contact 2, the fourth contact 4, and the third contact 3 are connected. The generator B+ signal flows through the second contact 2 and the fourth contact 4 to the third contact 3. The third contact 3 is connected to the rear control panel electrical system; that is, this third contact is connected to the 15-position fuse via a wire before being connected to the rear control panel electrical system (i.e., connected to...). Figure 2 At connection point A, power is supplied to the rear control panel electrical system. Similarly, contacts 6 and 7, 14 and 15, and 10 and 11 are connected. Contacts 7, 15, and 11 are respectively connected to the transmission oil pressure gauge, fuel gauge, and transmission oil temperature gauge on the rear control panel (i.e., connected to...). Figure 2 (The rear transmission oil temperature gauge, rear fuel level gauge, and rear transmission oil pressure gauge are connected one by one.) At this time, the driller's control system is in working condition, and the chassis electrical equipment is de-energized.

[0040] The instrument display module of the aforementioned driller control circuit is the rear operation instrument panel, such as... Figure 3 As shown, it includes an engine parameter display 101, an instrument light switch 104, a horn button 105, a rear fuel gauge 106, a rear air pressure gauge 103, a rear transmission oil pressure gauge 102, a rear transmission oil temperature gauge 107, a rear transmission gear position indicator 108, an ignition switch 109, an emergency stop switch 1010, as well as multiple covers, related sheet fuses, relays, and connecting wires, etc.

[0041] The aforementioned changeover switch is a low-voltage switch that switches between multiple circuits, changing the connection of a circuit from one group to another; the ignition switch is the switch for the ignition system, freely opening or closing the main circuit of the ignition coil, and is the master gate controlling the entire vehicle's electrical system; the instrument light switch is used as the power switch for the instrument backlight, controlling the backlight's on / off state by opening and closing; the horn button controls the horn's operation; pressing it activates the horn, and releasing it stops the horn; a relay is an electrical control device used in control circuits, essentially an "automatic switch" that uses a small current to control a large current, playing a safety protection role in the circuit; instrument The gauges reflect the operating status of various vehicle systems. The rear fuel gauge shows the amount of fuel in the tank; the rear tire pressure gauge shows the tire pressure in the lines; the rear transmission fluid pressure gauge shows the transmission fluid pressure; the rear transmission fluid temperature gauge shows the transmission fluid temperature; the horn button is a horn device used to warn pedestrians and other vehicles to attract attention and ensure driving safety; a chip fuse is an electrical device that breaks the circuit by melting its own heat when the current exceeds a specified value, effectively protecting the circuit; wires, used as electrical wires and cables, are made of copper or aluminum and are used to conduct current or heat, connecting system equipment.

[0042] The switching circuit proposed in this embodiment uses a switching switch to achieve circuit switching. When the switching switch is not turned on, the chassis electrical equipment is powered on and works normally. When the switching switch is turned on, the chassis electrical equipment is de-energized and stops working, while the driller's electrical equipment is powered on and starts working. This allows the chassis control circuit to control driving operations and the driller control circuit to control well workover operations to work independently without interfering with each other. This enables single-person safe operation, improves operational safety, reduces the time wasted in multi-person operations, and improves work efficiency.

[0043] Example 2

[0044] This embodiment provides a method for switching between driving and driller control of a vehicle-mounted well workover equipment, based on the driving and driller control switching circuit of the vehicle-mounted well workover equipment disclosed in Embodiment 1, and includes the following steps:

[0047] When the vehicle is parked at idle speed, turning on the switch de-energizes the chassis control circuit, stops the chassis electrical equipment from operating, energizes the driller control circuit, and enables the driller electrical equipment to operate normally. The instrument display module of the driller electrical equipment displays the status information of the driller control circuit, and the well workover operation is controlled based on the driller control circuit.

[0048] In this embodiment, the method for switching between driving and driller control of the vehicle-mounted well workover equipment is as follows:

[0051] Step 3: With the vehicle parked and idling, turn on the switch. The chassis electrical equipment will be de-energized and will not function properly, and the vehicle will not be able to move. The driller's platform equipment will be powered on and will begin working, allowing well repair operations to be carried out.

[0052] This embodiment achieves circuit switching through a changeover switch, which brings convenience and safety benefits. It allows for easier operation of well workover equipment, thereby effectively improving the safety of well workover operations, ensuring the safety of workers and equipment during the work process, and increasing the work efficiency of mechanical equipment in well workover operations. At the same time, under independent and safe operation conditions, it reduces the damage rate and depreciation rate of equipment, greatly extending the service life of oilfield workover rigs.
