Description

Technical Field

[0001] This utility model relates to the field of hydraulic well workover rig technology, specifically to an explosion-proof safety control system for a hydraulic well workover rig. Background Technology

[0002] Hydraulic workover rigs are multi-purpose equipment that saves costs and is safe to use. They can be used for operations such as sand removal, replacement of completion tubing, casing leak repair, and pump inspection. The diesel engine converts fuel into mechanical energy. Through the mechanical power output of the diesel engine, increased flow rate, and the combined work with other hydraulic components, the overall efficiency and reliability of the hydraulic system are significantly improved. It can be seen that the control system of the diesel engine is particularly important in this system. Therefore, an explosion-proof safety control system for hydraulic workover rigs is needed.

[0003] Existing hydraulic workover rigs typically lack explosion-proof safety monitoring capabilities. When encountering hazardous conditions in the aforementioned environments, the engine may fail to respond promptly, potentially leading to combustion and explosion hazards for the entire system. Furthermore, existing explosion-proof safety control systems are not sufficiently safe and reliable, making them incompatible with various types of electronically controlled fuel injection diesel engines and unable to eliminate potential hazardous conditions in oilfield applications, resulting in unstable operation of the diesel engine. In addition, existing explosion-proof safety control systems typically lack anti-bend wire functionality, meaning they cannot protect the connections of wiring and terminals. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof safety control system for hydraulic workover rigs, in order to solve the problems mentioned in the background art, such as the lack of safety and reliability of explosion-proof safety control systems during use, and the fact that they usually do not have the function of preventing folding lines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof safety control system for a hydraulic well workover rig, comprising a container, a core control box mounted inside the container via a bracket, a plurality of wiring ports on the surface of the core control box, connecting wires plugged into the surfaces of the wiring ports, a diesel engine body mounted on the inner wall of the container, an air intake pipe mounted on the surface of the diesel engine body, a pipe body mounted inside the container and connected to the diesel engine body, an air intake hood mounted inside the container, hydraulic components mounted on the inner wall of the container, a safety and reliable mechanism provided on the inner wall of the container, and an anti-bending mechanism provided on the surfaces of the wiring ports and connecting wires.

[0006] Preferably, the hydraulic components are connected to the interior of the air intake pipe via a pipeline. Two sets of plugs are symmetrically installed on the surface of the core control box. The surface of the core control box has a DC power supply, a main line connector, a remote cable interface, a charging connector, an AC power supply cable interface, a gas cable interface, a lighting cable interface, a bell cable interface, a smoke cable interface, and an exhaust temperature cable interface.

[0007] Preferably, the safety and reliability mechanism comprises an explosion-proof gas probe, an explosion-proof smoke probe, an explosion-proof flame probe, an explosion-proof exhaust temperature probe, an intake cut-off device, an explosion-proof battery, and an explosion-proof speed sensor. An explosion-proof gas probe is installed on the inner wall of the container, and its output is electrically connected to the input of the core control box. Similarly, an explosion-proof smoke probe is installed on the inner wall of the container, and its output is electrically connected to the input of the core control box. An explosion-proof flame probe is installed on the surface of the pipe, and its output is electrically connected to the input of the core control box.

[0008] Preferably, an explosion-proof exhaust temperature probe is mounted on the surface of the hydraulic component, and the output end of the explosion-proof exhaust temperature probe is electrically connected to the input end of the core control box. An explosion-proof speed sensor is mounted on the surface of the air intake hood, and the output end of the explosion-proof speed sensor is electrically connected to the input end of the core control box. An explosion-proof battery is installed inside the container, and the output end of the explosion-proof battery is electrically connected to the input end of the core control box. An air intake cut-off device is mounted on the surface of the hydraulic component, and the output end of the air intake cut-off device is electrically connected to the input end of the core control box.

[0009] Preferably, the anti-bend mechanism consists of a positioning mounting block, a rubber pad, a silicone pad, and a protective sleeve. A protective sleeve is provided on the surface at the bottom of the wiring port, and positioning mounting blocks are installed on the surface of the protective sleeve. The positioning mounting blocks and the surface of the wiring port are engaged with each other.

[0010] Preferably, a silicone pad is installed on the inner wall of the connector, and a rubber pad for protecting the connection between the connector and the connecting wire is installed on the inner wall of the silicone pad, and the inner wall of the rubber pad is in contact with the surface of the connecting wire.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the explosion-proof safety control system of the hydraulic workover rig not only allows the safety control system to be adapted to various types of electronically injected diesel engines, eliminating potential dangerous working conditions in oilfield applications and enabling the diesel engine body to operate more safely and reliably, but also enables the safety control system to protect the connection points of the connecting wires and terminals. At the same time, it can prevent dust from entering the interior of the core control box through the gaps between the connecting wires and terminals, thus preventing damage to the components inside the core control box.

[0012] 1. Equipped with safe and reliable mechanisms, the system can supply power and store electrical energy through an explosion-proof battery. An explosion-proof gas detector can detect the presence of flammable or explosive gases in the engine's environment. When the diesel engine is out of control, the intake cut-off device can force it to stop. An explosion-proof smoke detector can detect abnormal smoke in the engine's environment. An explosion-proof flame detector can detect open flame sources. An explosion-proof exhaust temperature detector monitors the exhaust temperature. An explosion-proof speed sensor detects whether the engine's actual speed exceeds its maximum permissible speed. This ensures the safety and reliability of the control system, making it compatible with various types of electronically controlled fuel injection diesel engines. It eliminates potential hazardous conditions in oilfield applications, enabling safer and more reliable stable operation of the diesel engine.

[0013] 2. By incorporating an anti-bending mechanism, the user places the protective sleeve at the bottom of the wiring port, causing the protective sleeve to engage with the positioning block, which then positions the protective sleeve. When the connecting wire is inserted into the wiring port, the rubber pad on the inner wall of the port moves to contact the surface of the connecting wire. The combined action of the rubber pad and the silicone pad protects the connection point, preventing bending at the junction of the wire and the wiring port. This achieves the anti-bending function of the safety control system, protecting the connection between the wire and the wiring port during use. Simultaneously, it prevents dust from entering the core control box through the gap between the wire and the wiring port, thus avoiding damage to the internal components. Attached Figure Description

[0024] The structure of the explosion-proof safety control system for a hydraulic well workover rig provided by this utility model is as follows: Figures 1 to 8 As shown, the system includes a container 1, with a core control box 102 mounted on the inner wall of the container 1 via a bracket. Two sets of plugs 1022 are symmetrically mounted on the surface of the core control box 102. A DC power supply 1021, a main line connector 1023, a remote cable interface 1024, a charging connector 1025, an AC power supply cable interface 1026, a gas cable interface 1027, a lighting cable interface 1028, a bell cable interface 1029, and a smoke cable interface are all mounted on the surface of the core control box 102. 1030. An exhaust temperature cable interface 1031 is installed on the surface of the core control box 102. If the voltage of the core control box 102 is DC24V / AC220V, the maximum current of the contact is 6A; if it is AC380, the maximum current is 4A. Several wiring ports 107 are installed on the surface of the core control box 102. Connecting wires 108 are plugged into the surface of the wiring ports 107. A diesel engine body 103 is installed on the inner wall of the container 1. An intake pipe 105 is installed on the surface of the diesel engine body 103. A pipe body 104 is installed inside the container 1 and is connected to the diesel engine body 103. An air intake hood 106 is installed inside the container 1. A hydraulic component 101 is installed on the inner wall of the container 1 and is connected to the inside of the intake pipe 105 through a pipe.

[0025] Furthermore, such as Figure 2 and Figure 3As shown, a safety and reliability mechanism 2 is installed on the inner wall of container 1. This mechanism 2 consists of an explosion-proof gas probe 21, an explosion-proof smoke probe 22, an explosion-proof flame probe 23, an explosion-proof exhaust temperature probe 24, an intake cut-off device 25, an explosion-proof battery 26, and an explosion-proof speed sensor 27. The explosion-proof gas probe 21 is installed on the inner wall of container 1, and its output is electrically connected to the input of the core control box 102. Similarly, the explosion-proof smoke probe 22 is installed on the inner wall of container 1, and its output is electrically connected to the input of the core control box 102. An explosion-proof flame probe 23 is installed on the surface of the pipe body 104. The explosion-proof flame probe 23... The output end is electrically connected to the input end of the core control box 102. An explosion-proof exhaust temperature probe 24 is installed on the surface of the hydraulic component 101. The output end of the explosion-proof exhaust temperature probe 24 is electrically connected to the input end of the core control box 102. An explosion-proof speed sensor 27 is installed on the surface of the air intake hood 106. The output end of the explosion-proof speed sensor 27 is electrically connected to the input end of the core control box 102. An explosion-proof battery 26 is installed inside the container 1. The output end of the explosion-proof battery 26 is electrically connected to the input end of the core control box 102. An air intake cut-off device 25 is installed on the surface of the hydraulic component 101. The output end of the air intake cut-off device 25 is electrically connected to the input end of the core control box 102.

[0026] During implementation, the explosion-proof battery 26 provides power and energy storage to the control system. The explosion-proof gas probe 21 detects the concentration of flammable and explosive gases in the engine's environment. When the diesel engine 103 is in an uncontrolled state, the intake cut-off device 25 forces it to stop. The explosion-proof smoke probe 22 detects abnormal smoke in the environment where the diesel engine 103 is located. The explosion-proof flame probe 23 detects open flame sources in the environment where the diesel engine 103 is located. The explosion-proof exhaust temperature probe 24 monitors the exhaust temperature of the gas. The explosion-proof speed sensor 27 detects whether the actual engine speed exceeds the maximum allowable speed and converts these signals into electrical signals, which are then sent to the core control box 102. The core control box 102 enables human-machine interaction and interlocks key data, adding a full-scenario safety control scheme to achieve a safe and reliable safety control system.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, the surface of the connector 107 and the connecting wire 108 is provided with an anti-bending mechanism 3. The anti-bending mechanism 3 consists of a positioning mounting block 31, a rubber pad 32, a silicone pad 33, and a protective sleeve 34. The surface of the connector 107 at the bottom position is provided with a protective sleeve 34. The surface of the protective sleeve 34 is equipped with a positioning mounting block 31. The positioning mounting block 31 and the surface of the connector 107 are engaged with each other. The inner wall of the connector 107 is equipped with a silicone pad 33. The inner wall of the silicone pad 33 is equipped with a rubber pad 32 for protecting the connection between the connector 107 and the connecting wire 108. The inner wall of the rubber pad 32 is in contact with the surface of the connecting wire 108.

[0028] During implementation, the user places the protective sleeve 34 at the bottom of the wiring port 107, causing the protective sleeve 34 to move the positioning mounting block 31 to the surface of the wiring port 107. Under the action of the positioning mounting block 31, the protective sleeve 34 is positioned and installed. When the connecting wire 108 is inserted into the surface of the wiring port 107, the rubber pad 32 on the inner wall of the wiring port 107 moves to contact the surface of the connecting wire 108. Under the combined action of the rubber pad 32 and the silicone pad 33, the connection of the connecting wire 108 can be protected, preventing the connection between the connecting wire 108 and the wiring port 107 from being bent, so as to realize the function of the safety control system to prevent bending.

[0029] Working Principle: In use, first place the container 1 in the designated location. The explosion-proof battery 26 supplies power to the control system and stores electrical energy. The explosion-proof gas detector 21 detects the presence of flammable or explosive gases in the engine's environment. When the diesel engine 103 is out of control, the intake cut-off device 25 forces it to stop. The explosion-proof smoke detector 22 detects abnormal smoke in the environment where the diesel engine 103 is located. The explosion-proof flame detector 23 detects open flame sources in the environment where the diesel engine 103 is located. The exhaust temperature probe 24 monitors the exhaust temperature of the gas. The explosion-proof speed sensor 27 detects whether the actual engine speed exceeds the maximum allowable speed of the engine and converts these signals into electrical signals to send to the core control box 102. The core control box 102 enables human-machine interaction and interlocks the control of key data, adding a full-scenario safety control scheme to achieve a safe and reliable function of the safety control system. This allows the safety control system to be adapted to various types of electronically injected diesel engines, eliminating potential dangerous conditions in oilfield applications and enabling the diesel engine body 103 to operate more safely and reliably.

[0030] Subsequently, when the connecting wire 108 is plugged into the surface of the wiring port 107, the connection point of the connecting wire 108 is prone to kinking. Furthermore, dust and other impurities can easily enter the interior of the core control box 102 through the gap between the wiring port 107 and the connecting wire 108. Before connecting the connecting wire 108, the user places the protective sleeve 34 at the bottom of the wiring port 107, causing the protective sleeve 34 to move the positioning mounting block 31 to the surface of the wiring port 107. Under the action of the positioning mounting block 31, the protective sleeve 34 is positioned and installed. When the connecting wire 108 is plugged into the surface of the wiring port 107, the rubber pad 32 on the inner wall of the wiring port 107 moves to... The surfaces of the connecting wires 108 are in contact, and the joint action of the rubber pad 32 and the silicone pad 33 can protect the connection of the connecting wires 108, preventing the connection between the connecting wires 108 and the terminal 107 from being bent. This achieves the anti-bent wire function of the safety control system, thus protecting the connection between the connecting wires 108 and the terminal 107 during use. At the same time, it can prevent dust from entering the core control box 102 through the gap between the connecting wires 108 and the terminal 107, which could damage the internal components of the core control box 102. Finally, the explosion-proof safety control system is put into use.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
