Technical Field

[0001] This invention relates to the field of power equipment maintenance technology, and in particular to a method and apparatus for hoisting components of power equipment. Background Technology

[0002] With the development of the national economy, the status of the power industry has gradually risen. As an important component of the power system, the safe and stable operation of power equipment plays a vital role in the effective transmission of electricity. Gas-insulated power equipment, such as gas-insulated switchgear (GIS), inevitably requires the replacement of internal mechanisms due to factors such as component aging, design defects, material defects, and accidental damage during operation.

[0003] Currently, replacement is carried out by using large cranes for hoisting and manual handling. However, due to the limited number of cranes and the weight of equipment components, as well as the low efficiency of manual handling, a long replacement time is required, resulting in low replacement efficiency of power equipment.

[0012] The control unit is connected to the electric mechanism and is used to control the electric mechanism to move the components of the power equipment to the target lifting point.

[0019] Optionally, the electric mechanism includes a stepper motor and a winch, wherein the stepper motor drives the horizontal double slide rail and the longitudinal single slide rail to move, and the winch controls the lifting and lowering of the hook.

[0020] Secondly, a method for hoisting components of power equipment is provided, applicable to any of the component hoisting devices for power equipment described in the first aspect above, comprising:

[0025] Optionally, determining the hoisting path based on the initial coordinate data and the target coordinate data includes:

[0026] Target distance data is obtained based on the initial coordinate data and the target coordinate data;

[0027] The hoisting path is determined based on the target distance data.

[0028] Optionally, the component controlling the power equipment moving along the hoisting path to the target hoisting point includes:

This greatly improves the accuracy and reliability of component installation and replacement operations on electrical equipment, as well as equipment replacement efficiency, thereby increasing maintenance efficiency.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0046] Currently, the installation and replacement of components on power equipment relies excessively on large equipment and manual labor. However, limitations in the number of cranes and the weight of equipment components, coupled with low efficiency when personnel are replacing heavy equipment components, lead to excessively long equipment downtime and significant safety hazards during equipment and component replacement and installation. Therefore, this application provides a component hoisting device for power equipment, comprising: a transverse double slide rail fixed to a base; two ends of a longitudinal single slide rail mounted on the transverse double slide rail; a hoisting tool mounting ring mounted on the longitudinal single slide rail; a chain hoist connected to the hoist; an electric mechanism for pushing the longitudinal single slide rail along the transverse double slide rail and / or pushing the chain hoist along the longitudinal single slide rail; and a control unit connected to the electric mechanism for controlling the electric mechanism to move the power equipment component to a target hoisting point, where the difference between the real-time coordinate data of the power equipment component and the target coordinate data of the target hoisting point satisfies a preset condition.

[0047] Please see Figures 1 to 3 As shown, Figures 1 to 3 This is a schematic diagram of the structure of a component hoisting device for power equipment provided in an embodiment of the present invention. The component hoisting device for power equipment includes: a base, a horizontal double slide rail, a vertical single slide rail, a hoisting tool mounting ring, an electric mechanism, and a control unit.

[0048] The transverse double slide rail is fixed to the base; both ends of the longitudinal single slide rail are installed on the transverse double slide rail; the lifting tool mounting ring is installed on the longitudinal single slide rail; a chain hoist is provided on the lifting tool mounting ring, and the chain hoist is connected to a hook; the electric mechanism is used to push the longitudinal single slide rail to move along the transverse double slide rail, and / or push the chain hoist to move along the longitudinal single slide rail; the control unit is connected to the electric mechanism and is used to control the electric mechanism to move the components of the power equipment to the target lifting point, where the difference between the real-time coordinate data of the components of the power equipment and the target coordinate data of the target lifting point meets a preset condition.

[0049] Specifically, the longitudinal single slide rail is installed along the track groove port of the transverse double slide rail, and bolts are used as stop pins and reinforcing anchors at the reserved flat screw holes of the transverse double slide rail. This prevents the longitudinal single slide rail from sliding out of the groove and also prevents the groove of the transverse double slide rail from deforming, which would prevent the longitudinal single slide rail from moving. The lifting tool installation ring is inserted into the longitudinal single slide rail groove from one end. After installing the base, longitudinal single slide rail, transverse double slide rail, and lifting tool installation ring, the chain hoist is attached to the lifting tool installation ring. This allows the longitudinal single slide rail to run along the transverse double slide rail and the chain hoist to move along the longitudinal single slide rail to above the object to be lifted (i.e., a component of electrical equipment, such as the linear isolating switch crank arm box on GIS equipment). After the object is lifted by the hook, the control unit controls the electric mechanism to push the longitudinal single slide rail and the chain hoist to move the object above the placement area. The chain hoist is then operated to lower the object, completing the lifting operation.

[0050] Specifically, the control unit connects to multiple relays, air switches, and infrared sensors installed on the component hoisting device via wired and / or wireless connections. It is primarily used to control the power supply to the hoisting device, the movement of the hoisting points, the raising and lowering of the hoisting ropes, and the acquisition of the hook position (i.e., the hoisting point position). This allows the electric mechanism to move the components of the electrical equipment to the target hoisting point. In this embodiment, electrical equipment replaces manual labor, improving the accuracy and reliability of equipment replacement and installation operations, and enhancing the stability of the hoisting process.

[0051] In one embodiment, the control unit can be connected to a third-party device via wired or wireless means. This third-party device can be a programmable logic controller (PLC) device and multiple digital display devices for display; it can also be a computer device, such as a microcomputer. The third-party device can process the data collected by the distance sensors mounted on the component lifting device and output corresponding excitations to the control unit to operate the component lifting device. Simultaneously, the third-party device can also display the three-dimensional coordinates of the hook.

[0052] Through the aforementioned connection, during the replacement of electrical equipment, the control unit can control the electric mechanism to move the components of the electrical equipment to the target lifting point via a transverse double slide rail, a longitudinal single slide rail, and a chain hoist. This significantly reduces replacement requirements, improves operational efficiency, and reduces reliance on large lifting equipment. It not only saves economic losses caused by prolonged power outages for maintenance but also avoids line downtime losses due to insufficient working safety distance of the crane boom. Furthermore, it avoids the limitations of manual handling on uneven platforms, reduces safety hazards during personnel movement of heavy objects, lowers operational risks for workers, and improves stability during lifting. This greatly improves the accuracy and reliability of component installation and replacement operations on electrical equipment, as well as equipment replacement efficiency, thereby increasing maintenance efficiency. In addition, the connection method employs a combination of portal frame and I-frame design, allowing the lifting base point to move freely on a plane at a certain height. This makes lifting more flexible and eliminates the need for frequent disassembly and reassembly of component lifting devices due to different lifting points for electrical equipment components, greatly improving lifting efficiency.

[0053] Optionally, the base is provided with a column, and the upper end of the column is bolted to the transverse double slide rail.

[0054] In one embodiment, the base and the column can be connected by welding.

[0055] In one embodiment, there may be four bases, each base is provided with a column, and the upper end of each column is bolted to the horizontal double slide rail.

[0056] Specifically, the upper end of the column has pre-drilled bolt holes, allowing the horizontal double slide rails to be installed parallel to each other in the pre-drilled bolt holes at the upper end of the four columns. The bolted connection facilitates disassembly and transport, saving time and improving equipment replacement and installation efficiency.

[0057] For example, the base can be connected and fixed to the flange face of the power equipment by bolts.

[0058] Optionally, the base is circular with lugs, and the diameter of the circular lugs is smaller than the screw hole spacing at the pre-installation location.

[0059] A circular base with ears indicates that the base is circular in shape and has protruding "ear"-like structures on both sides or around the circle, which helps to increase the stability and functionality of the base. The pre-installed screw holes of the ear-like structures on the base must correspond to the pre-installed bolt positions on the flange face of the electrical equipment.

[0060] In this embodiment, because the base is circular with ears, and the diameter of the circle within the ear is smaller than the pre-installation bolt hole spacing, the ear-shaped structure can fit tightly against the flange surface of the power equipment, improving its stability. Furthermore, the pre-installation bolt holes on the ear-shaped structure of the mounting base must allow bolts to pass through to connect with the pre-installation bolt positions on the flange surface of the power equipment. The GIS structure can be used to fix the foundation frame (including the base, columns, and transverse double slide rails), effectively ensuring the stability of the load-bearing structure during hoisting.

[0061] Optionally, the transverse double slide rail and the longitudinal single slide rail are connected by a notch-embedded connection; and / or

[0062] like Figure 4 As shown, the hoisting tool mounting ring and the longitudinal single slide rail are connected by a limiting embedded connection.

[0063] The notch-embedded connection refers to a connection method between two components, where one component has a notch and the other component has a corresponding embedded portion, allowing them to fit together tightly. This connection method provides a stable and secure connection, ensuring proper alignment and fixation between the components. In this application, the transverse double slide rail has a notch, and the longitudinal single slide rail has an embedded portion, so that the connection between the transverse double slide rail and the longitudinal single slide rail can fit together tightly.

[0064] In this embodiment, the notch-embedded connection and the limiting embedded connection facilitate the installation and disassembly of the component hoisting device, thereby saving the time for installing and replacing components on the power equipment and improving the efficiency of component installation and replacement on the power equipment.

[0065] Optionally, multiple seat belt loops are provided on the outer side of the transverse double slide rail.

[0066] In one embodiment, four seat belt loops can be provided on the outer side of the transverse double slide rails, and the four seat belt loops can be arranged symmetrically. For example, two seat belt loops can be provided at each end of each side of the transverse double slide rails.

[0067] In this embodiment, by setting multiple safety belt hanging rings on the outside of the transverse double slide rails, the problem of lacking safety belt hanging points for high-altitude operations can be solved.

[0068] Optionally, a distance measuring sensor is installed on the transverse double slide rail and the longitudinal single slide rail respectively, and the distance measuring sensor is used to measure the real-time coordinate data of the components of the power equipment.

[0069] Among them, the distance measuring sensor can be an electronic distance measuring ruler, such as a laser distance measuring instrument or an infrared distance measuring sensor.

[0070] In one embodiment, the component hoisting device of the power equipment of this application is equipped with four distance measuring sensors. Two distance measuring sensors (such as laser rangefinders) are respectively installed on the transverse double slide rail to test the movement distance of both sides of the longitudinal single slide rail on the transverse double slide rail (e.g., installed at the end or beginning of the longitudinal single slide rail when it moves to the transverse double slide rail, at which time the initial movement distance of the longitudinal single slide rail is 0); one distance measuring sensor (such as laser rangefinder) is used to test the movement distance of the lifting point (hook) on the longitudinal single slide rail. If installed at any end of the longitudinal single slide rail, it can be close to the groove of the longitudinal single slide rail to improve the measurement accuracy; the other sensor can be installed on the hoisting tool mounting ring or on the longitudinal single slide rail to measure the extension length of the hoisting rope by detecting the extension length of the measuring ruler.

[0071] Optionally, the electric mechanism includes a stepper motor and a winch, wherein the stepper motor drives the horizontal double slide rail and the longitudinal single slide rail to move, and the winch controls the lifting and lowering of the hook.

[0072] Specifically, the electric mechanism includes three stepper motors, one winch, and an auxiliary hook. The electric mechanism is the specific execution part of the component lifting device for lifting operations.

[0073] In one embodiment, the component hoisting device for power equipment can acquire target coordinate data of the target hoisting point; acquire initial coordinate data of the components of the power equipment; determine the hoisting path based on the initial coordinate data and the target coordinate data; and control the hoisting path of the components of the power equipment to move to the target hoisting point.

[0074] Please see Figure 5 As shown, Figure 5 This is a schematic flowchart of a method for hoisting components of power equipment according to an embodiment of the present invention. This method can be applied to applications such as... Figures 1 to 3 The power equipment component hoisting device (hereinafter referred to as the component hoisting device) shown is used in this model training method, which includes the following steps:

[0075] 101: Obtain the target coordinate data of the target lifting point.

[0076] The target lifting point is the lifting point position where the component of the power equipment is moved to a preset location. Specifically, it is the lifting point position where the difference between the real-time coordinate data of the component and the target coordinate data of the target lifting point satisfies a preset condition. The target coordinate data can be data containing the coordinate values ​​of that position in the X, Y, and Z directions.

[0077] In one embodiment, the target coordinate data of the target lifting point can be input through a third-party device connected to the control unit, thereby enabling the control unit of the component lifting device to obtain the target coordinate data of the target lifting point.

[0078] 102: Obtain the initial coordinate data of the components of the power equipment.

[0079] The initial coordinate data can include the coordinate values ​​of the power equipment in the X, Y, and Z directions when the hoisting operation has not yet started.

[0080] In one embodiment, the initial coordinate data of the components of the power equipment can be measured based on an infrared sensor, and the initial coordinate data can be sent to the control unit via Bluetooth or other means, so that the control unit can obtain the initial coordinate data of the components of the power equipment.

[0081] 103: Determine the hoisting path based on the initial coordinate data and the target coordinate data.

[0082] The hoisting path may include the length of the hoisting rope, the direction and distance of movement of the longitudinal single slide rail on the transverse double slide rail, and the direction and distance of movement of the hoisting tool mounting ring on the longitudinal single slide rail. The order of movement of the two is not specifically limited and can be adjusted according to the actual application scenario.

[0083] In one embodiment, determining the hoisting path based on the initial coordinate data and the target coordinate data includes:

[0084] Target distance data is obtained based on the initial coordinate data and the target coordinate data;

[0085] The hoisting path is determined based on the target distance data.

[0086] Specifically, the difference between the initial coordinate data of the components of the power equipment and the target coordinate data of the target lifting point can be calculated to obtain the target distance data. For example, assuming the target data is (5,10,5) and the initial coordinate data is (2,4,3), then the coordinate difference is (5-2, 10-4, 5-3), which is (3,6,2). This indicates that the lifting tool's mounting ring moves 3 units in the X direction, 6 units in the Y direction, and 2 units in the Z direction, which is the lifting path.

[0087] Optionally, the dimensional information of the power equipment components, including length, width, and height, can be obtained through manual input or other methods, and the initial coordinate data of the power equipment components can be adjusted based on this dimensional information. For example, if the initial coordinate data of a power equipment component is the center point on its top surface, the height of the component can be added to the Z-direction coordinate value in the initial coordinate data. The X-direction and Y-direction coordinate values ​​in the initial coordinate data can also be adjusted according to the location of the corresponding coordinate point in the initial coordinate data to improve the accuracy of hoisting the component into the placement area.

[0088] 104: Control the components of the power equipment to move along the hoisting path to the target hoisting point.

[0089] Specifically, the power equipment can be controlled to move along the hoisting path to the target hoisting point at a preset speed. This speed can be a speed set based on empirical data or a dynamically adjustable speed. In one embodiment, the component controlling the power equipment to move along the hoisting path to the target hoisting point includes:

[0090] Obtain the real-time coordinate data of the components of the power equipment;

[0091] The real-time moving speed of the power equipment is determined based on the real-time coordinate data and the target coordinate data.

[0092] The components controlling the power equipment move along the hoisting path to the target hoisting point at the real-time moving speed.

[0093] Real-time coordinate data includes the real-time coordinate values ​​of the power equipment in the X, Y, and Z directions during the hoisting operation. Specifically, the real-time coordinate value in the X direction refers to the coordinate value of the longitudinal single guide rail on the transverse double guide rail, and the real-time coordinate value in the Y direction refers to the coordinate value of the hoisting tool's mounting ring.

[0094] Real-time coordinates can be obtained by measuring with an infrared sensor.

[0095] Specifically, the real-time moving speed of the power equipment can be determined by calculating the difference between the real-time coordinate data and the target coordinate data, and the power equipment can be controlled to move along the hoisting path at the actual moving speed to the target hoisting point and then stop.

[0096] For example, the real-time movement speed can be determined according to the following formula:

[0097]

[0098] Where V is the real-time moving speed, and L is the square root of the difference between the real-time coordinate data of the lifting component of the power equipment and the coordinate data of the target lifting point in the X direction and the Y direction, expressed as:

[0099]

[0100] Where x is the difference in the X-direction between the real-time coordinate data of the component being hoisted and the coordinate data of the target hoisting point of the power equipment, and y is the difference in the Y-direction between the real-time coordinate data of the component being hoisted and the coordinate data of the target hoisting point of the power equipment.

[0101] In one embodiment, when the difference between the real-time coordinate data of the components of the power equipment and the target coordinate data meets a preset condition (such as a difference of 0), the control unit controls the electric mechanism to stop operating.

[0102] In this embodiment, the component hoisting device can plan the optimal hoisting path based on the initial coordinate data and the target coordinate data, reducing hoisting deviations caused by human error, ensuring that the hoisted power equipment can be accurately moved to the target hoisting point, saving hoisting operation time, and improving the efficiency of power equipment installation and replacement.

[0103] like Figure 6 As shown, another hoisting process diagram is provided, including:

[0104] S10: Utilize infrared sensors installed on the component hoisting device to measure the coordinates (including initial and real-time coordinate data) of the hoisted object (i.e., components of the power equipment) in the X, Y, and Z directions, and transmit the coordinate data to the data processing unit (i.e., control unit) via Bluetooth communication.

[0105] S20: The control unit receives the target coordinate data of the target lifting point and performs lifting path planning.

[0106] Specifically, S20 includes S21 to S23:

[0107] S21: Obtain the current coordinates of the hoisted object through an infrared sensor and transmit them to the data unit; manually input the target hoisting point coordinates (i.e., target coordinate data);

[0108] S22: The data processing unit calculates the difference between the current coordinates (initial coordinate data and real-time coordinate data) of the hoisted object and the coordinates of the target hoisting point in real time. Based on the difference, the data processing unit calculates the distance that needs to be moved in the X, Y and Z directions.

[0109] S23: The data processing unit plans the hoisting path according to the required distance and sends the motion command to the motor.

[0110] S30: The data processing unit adaptively adjusts the motor speed (i.e., real-time moving speed) and stops based on distance data and target lifting point.

[0111] Specifically, S30 includes S31 to S33:

[0112] S31: The data processing unit calculates the difference between the real-time coordinates of the hoisted object and the coordinates of the target hoisting point in real time;

[0113] S32: The data processing unit calculates the speed of the motor according to the following formula and controls the moving speed of the hoisted object.

[0114] For example, the real-time movement speed can be determined according to the following formula:

[0115]

[0116] Where V is the real-time moving speed, and L is the square root of the difference between the real-time coordinate data of the lifting component of the power equipment and the coordinate data of the target lifting point in the X direction and the Y direction, expressed as:

[0117]

[0118] Where x is the difference in the X-direction between the real-time coordinate data of the component being hoisted and the coordinate data of the target hoisting point of the power equipment, and y is the difference in the Y-direction between the real-time coordinate data of the component being hoisted and the coordinate data of the target hoisting point of the power equipment.

[0119] S33: The motor stops moving when the difference between the real-time coordinates of the hoisted object and the coordinates of the target hoisting point is 0.

[0120] S40: Automatically reach the target lifting point according to the optimal lifting path planned by the data processing unit.

[0121] The above describes the component hoisting device and hoisting process for the power equipment described in this application.

[0122] As described above, this application provides a component hoisting device and hoisting process for power equipment. The component hoisting device includes a base, a transverse double slide rail, a longitudinal single slide rail, a hoisting tool mounting ring, an electric mechanism, and a control unit. The transverse double slide rail is fixed to the base. Both ends of the longitudinal single slide rail are mounted on the transverse double slide rail. The hoisting tool mounting ring is mounted on the longitudinal single slide rail. A chain hoist is provided on the hoisting tool mounting ring, and the chain hoist is connected to a hook. The electric mechanism is used to push the longitudinal single slide rail to move along the transverse double slide rail, and / or push the chain hoist to move along the longitudinal single slide rail. The control unit is connected to the electric mechanism and is used to control the electric mechanism to move the component of the power equipment to a target hoisting point. The target hoisting point is the position where the difference between the real-time coordinate data of the component of the power equipment and the target coordinate data of the target hoisting point meets a preset condition. Through the aforementioned connections, during the replacement of electrical equipment, the control unit can control the electric mechanism to move the components of the electrical equipment to the target lifting point via a transverse double slide rail, a longitudinal single slide rail, and a chain hoist. This significantly reduces replacement requirements, improves operational efficiency, and reduces reliance on large lifting equipment. It not only saves economic losses caused by prolonged power outages for maintenance but also avoids line downtime losses due to insufficient working safety distance of the crane boom. Furthermore, it avoids the limitations of manual handling on uneven platforms, reduces safety hazards during the movement of heavy objects, lowers the operational risks for workers, and improves stability during hoisting.
