Abstract
Description
Technical Field
[0001] This invention relates to the field of equipment installation technology, and in particular to a GIS switch lifting and transmission fixture. Background Technology
[0002] The maintenance and replacement of GIS (Gas Insulated Metal Enclosed Switchgear) is a crucial link in ensuring the stable operation of the power grid. Chinese invention patent application CN2024100309127 discloses a heavy-duty intelligent GIS moving and installation platform, including a gantry main frame for moving and installing heavy GIS equipment. The gantry main frame includes two parallel and spaced upper frames and two lower frames. A first folding sliding assembly capable of extending and retracting in a first direction is provided between the two upper frames, and a second folding sliding assembly capable of extending and retracting in a second direction is provided between the upper and lower frames. A slewing device for a steering system is installed at the bottom of the lower frames. A control valve in the hydraulic main valve control cabinet can adjust the walking direction of the heavy-duty intelligent GIS moving and installation platform by controlling the operation of a first hydraulic motor. Using hydraulic power as the driving force ensures stronger deformation and walking power for the heavy-duty intelligent GIS moving and installation platform. The above application suspends heavy objects on the gantry main frame with adjustable width and height, and the gantry column frame is driven by a walking system to transport the GIS equipment to its destination.
[0003] However, with the expansion of the power grid and the demand for intelligent upgrades of equipment, the GIS switch replacement method relying on the aforementioned large hoisting machinery has gradually revealed multiple limitations: First, the equipment layout within substations is compact, and the installation area of the GIS switch contains a large number of other devices, which is not conducive to the deployment of hoisting equipment. Moreover, the use of hoisting equipment requires a large working area, which is easily constrained by site conditions, resulting in limited construction space. Second, the use of hoisting equipment carries high safety risks. Problems such as the shift of the GIS switch's center of gravity and insufficient stability of the hoisting equipment during hoisting may lead to collision damage to the GIS switch or personal injury. Finally, in order to allow the aforementioned large hoisting machinery to carry the GIS switch horizontally, it is necessary to remove equipment such as the upper current transformer and side columns. The process is cumbersome and the power outage period is long. At the same time, relying on large machinery and multiple people for cooperation results in high labor and time costs, and the construction efficiency and economy are not ideal. Summary of the Invention
[0004] The purpose of this invention is to provide a GIS switch lifting and transmission fixture to solve the problems of GIS switch replacement being easily restricted by site conditions, construction safety risks, and low construction efficiency.
[0005] Based on this, the present invention provides a GIS switch lifting and conveying fixture, comprising: The base has wheels at its bottom and direction adjustment tubes on both sides of the wheels. The direction of the wheels can be adjusted by inserting a pry bar into the direction adjustment tubes and turning it. The top of the base has multiple first telescopic rods. The first telescopic rods are arranged along the Z direction. The multiple first telescopic rods are arranged in pairs at intervals. Each pair of first telescopic rods is used to support the GIS switch. The support frame is provided in at least two parts, and multiple support frames are arranged sequentially along the X direction. Each support frame is connected to a pair of first telescopic rods. A tractor unit is located at the front or rear end of the base. The top of the tractor unit is equipped with an auxiliary bracket and a third telescopic rod. The tractor unit is used to drive the base to move.
[0006] In some embodiments of this application, the base includes a front adjustment frame, a rear adjustment frame, and a second telescopic rod arranged sequentially along the X direction. The front adjustment frame is fixedly connected to the second telescopic rod, and the end of the second telescopic rod away from the front adjustment frame is fixedly connected to the rear adjustment frame. At least one support frame is provided on both the front adjustment frame and the rear adjustment frame.
[0007] In some embodiments of this application, the first telescopic rod is an electro-hydraulic rod, and the base is provided with a power supply, a controller and an emergency stop switch. The controller is electrically connected to the first telescopic rod, the power supply and the emergency stop switch.
[0008] In some embodiments of this application, an interface for an emergency manual pump is fixedly provided on the base, which can be connected to an emergency manual pump when necessary. The emergency manual pump is used to drive the first telescopic rod.
[0009] In some embodiments of this application, the central recess of the support bracket forms an assembly groove, the support bracket is arranged in an arc shape, and the GIS switch is disposed in the assembly groove.
[0010] In some embodiments of this application, a rubber pad is provided in the assembly slot, and the rubber pad is located between the support frame and the GIS switch.
[0011] In some embodiments of this application, a level is fixedly installed on the support frame.
[0012] In some embodiments of this application, a ratchet cable tie is fixedly provided on the support frame.
[0013] In some embodiments of this application, a pressure sensor and a force signal transmitter are fixedly mounted on the support frame.
[0014] In some embodiments of this application, the tractor is an electric tank, and an auxiliary bracket and a third telescopic rod are fixedly installed on the top of the tractor.
[0015] This invention provides a GIS switch transmission fixture, which has the following advantages compared with the prior art: This application provides a GIS switch lifting and transmission fixture, including a base, a support frame, and a traction vehicle. The base is fixedly equipped with wheels to enable its movement. Direction adjustment tubes are provided on both sides of the wheels; the direction of the wheels can be adjusted by inserting a pry bar into the direction adjustment tube and turning it. Multiple first telescopic rods are fixedly installed on the top of the base, all arranged along the Z-direction. The first telescopic rods are arranged in pairs at intervals, and each pair of first telescopic rods is used to lift the GIS switch. At least two support frames are sequentially arranged above the base along the X-direction, and each support frame is connected to the two pairs of first telescopic rods, i.e., the support frame is fixedly connected to the first telescopic rod, and the first telescopic rod is fixedly connected to the base. A traction vehicle is also provided at the front or rear end of the base, used to drive the base to move synchronously. The top of the traction vehicle is equipped with an auxiliary bracket and a third telescopic rod, which can lift the GIS switch.
[0016] Based on the above structure, before removing the GIS switch, complete the gas recovery and ensure the pressure in each chamber reaches the predetermined value as required. Then, move the base directly under the GIS switch, activate the first telescopic rods to lift the support frame upwards until it bears force, then stop. At this point, the GIS switch rests on the support frame. Observe the pressure values of each pressure sensor, adjust the first telescopic rods to balance the force, and use ratchet straps to bind the GIS switch to the support frame. Then, remove the connecting bolts of the two flanges on the upper part of the GIS switch and remove the support legs at both ends. Next, activate the first telescopic rods to slowly lower them synchronously by about 20cm, and then remove the connecting conductors at the center of the two flanges. Before transferring the GIS switch, move the tractor to one end of the GIS switch and activate the third telescopic rod on the tractor to lift the GIS switch upwards. Alternatively, adjust the pair of first telescopic rods of the adjacent tractor to lower appropriately. After the tractor bears the load, start the tractor to move the GIS switch and base forward, backward, or turn to transport the GIS switch to the designated area. This completes the removal of the GIS switch.
[0017] Based on the above structure, when installing the GIS switch, move the base directly below the GIS switch. Activate the first telescopic rod to lift the GIS switch upwards until it is under load, then stop. Use ratchet straps to secure the GIS switch to the support frame. After removing the outriggers or raising the wooden blocks, move the tractor to one end of the GIS switch. Activate the third telescopic rod on the tractor to lift the GIS switch upwards. Alternatively, adjust the pair of first telescopic rods on adjacent tractors as needed. Once the tractor is under load, start the tractor to move the GIS switch and base forward, backward, or turn, translating the new GIS switch to the installation position (i.e., aligning the upper and lower flanges). Activate the third telescopic rod of the tractor to lower it and remove the tractor. After connecting the center conductor of the flange and completing the flange sealing, activate the first telescopic rod to lift the GIS switch upwards until the upper and lower flanges contact, then stop. Observe the pressure values of each pressure sensor and adjust the first telescopic rods to balance the load. Then install and tighten the bolts. Finally, install the GIS switch outriggers. Finally, remove the tractor and base, completing the GIS switch installation.
[0018] The first telescopic mast can be raised and lowered by a controller or a remote control. If both the controller and remote control malfunction and cannot stop the raising and lowering, pressing the emergency stop switch will cut off the power to the first telescopic mast and immediately stop the raising and lowering action. When the electrical control system of the first telescopic mast completely fails, the raising and lowering of the first telescopic mast can be operated by connecting an emergency manual pump to ensure the smooth completion of the removal or installation of the GIS switch.
[0019] Thus, this application sets up a base and support frame to lift the GIS switch from the bottom, and the structural width of the base, support frame, and tractor is smaller than the outer diameter of the GIS switch cylinder, so it is not affected by the columns on both sides of the GIS switch during movement; the tractor and base support frame work together in lifting and lowering, allowing it to cross ground obstacles such as anchor bolts and cable trays during movement. This application solves the problem of traditional hoisting equipment occupying a large construction space and being difficult to deploy; at the same time, it eliminates the risk of equipment damage or personnel injury caused by swaying during GIS switch hoisting, ensuring the safety of GIS switch replacement work; this application eliminates the need to remove surrounding equipment such as the upper current transformer and side columns, and the modular base and tractor separately complete the lifting and transmission operations, reducing reliance on other equipment, improving the efficiency of GIS switch replacement work, and reducing the overall construction cost.

[0022] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. In order to better clarify the structural design of this application, the traveling direction of the base during operation is defined as the X direction, the lifting direction of the support frame is defined as the Z direction, and the direction perpendicular to both the X and Z directions is defined as the Y direction.
[0023] like Figures 1 to 5 As shown, this application provides a GIS switch lifting and transmission fixture, including a base 1 and a support frame 2. The base 1 is fixedly equipped with traveling wheels 14 to realize the movement of the base 1. Multiple first telescopic rods 3 are fixedly installed on the top of the base 1. The multiple first telescopic rods 3 are all arranged along the Z direction and are arranged in pairs at intervals. Each pair of first telescopic rods is used to lift the GIS switch 8. At least two support frames 2 are arranged sequentially above the base 1 along the X direction. Each support frame 2 is connected to the two pairs of first telescopic rods 3, that is, the support frame 2 is fixedly connected to the first telescopic rods 3, and the first telescopic rods 3 are fixedly connected to the base 1. A traction vehicle 4 is also provided at the front end of the base 1. The traction vehicle 4 is used to drive the base 1 to move synchronously. The top of the traction vehicle 4 is provided with an auxiliary bracket 41 and a third telescopic rod 42, which can lift the GIS switch 8.
[0024] Based on the above structure, before removing the GIS switch 8, complete the gas recovery and ensure that the pressure in each gas chamber reaches the predetermined value as required. Then, move the base 1 directly below the GIS switch 8, activate the first telescopic rod 3 to lift the support frame 2 upwards until it is under pressure, then stop. At this point, the GIS switch 8 rests on the support frame 2 due to its lifting. Observe the pressure values of each pressure sensor 23, adjust each first telescopic rod 3 to balance the force, and use ratchet straps 24 to bind the GIS switch 8 to the support frame 2. At this time, remove the connecting bolts of the two flanges on the upper part of the GIS switch 8, and remove the support legs at both ends of the GIS switch 8. Then, activate each first telescopic rod 3 to slowly lower it synchronously by about 20cm, and then remove the connecting conductor at the center of the two flanges. When it is necessary to move the GIS switch 8, the towing vehicle 4 is moved to one end of the GIS switch 8, and the third telescopic rod 42 on the towing vehicle 4 is started to lift the GIS switch 8 upward. Alternatively, the pair of first telescopic rods 3 adjacent to the towing vehicle 4 can be appropriately lowered. After the towing vehicle 4 bears the load, it is started to move the GIS switch 8 and the base 2 forward, backward or turn, so as to move the GIS switch 8 and transfer it to the predetermined area. This completes the removal of the GIS switch 8.
[0025] Based on the above structure, when installing the GIS switch 8, move the base 1 directly below the GIS switch 8, activate the first telescopic rod 3 to lift the support frame 2 upwards until it bears force and then stop. Use ratchet straps 24 to secure the GIS switch 8 to the support frame 2. After removing the outriggers or raising the wooden blocks, move the tractor 4 to one end of the GIS switch 8. Activate the third telescopic rod 42 on the tractor 4 to lift the GIS switch 8 upwards. Alternatively, the pair of first telescopic rods 3 adjacent to the tractor 4 can be appropriately lowered. After the tractor 4 bears the load, start the tractor 4 to... Move the GIS switch 8 and base 1 forward, backward, or turn to position the GIS switch 8 for installation (aligning the upper and lower flanges). Lower the third telescopic rod 42 of the tractor 4 until it disengages. Remove the tractor 4. After connecting the center conductor of the flange and sealing the flange, activate the first telescopic rod 3 to lift the support frame 2 upwards until the upper and lower flanges contact. Observe the pressure values of each pressure sensor 23, adjust the first telescopic rods 3 to ensure balanced force, and then install and tighten the bolts. Finally, install the support legs of the GIS switch 8. Remove the tractor 4 and base 1, thus completing the installation of the GIS switch 8.
[0026] Thus, this application sets up a base 1 and a support frame 2 to lift the GIS switch 8 from the bottom. The structural width of the base 1, support frame 2, and tractor 4 is smaller than the outer diameter of the GIS switch 8 cylinder, so it is not affected by the columns on both sides of the GIS switch 8 during movement. The tractor 4 and the support frame 2 of the base 1 work together in lifting and lowering, allowing it to cross ground obstacles such as anchor bolts and cable trays during movement. This application solves the problem of existing hoisting equipment occupying a large construction space and being difficult to deploy; it eliminates the risk of equipment damage or personnel injury caused by swaying during GIS switch 8 hoisting, ensuring the safety of GIS switch 8 replacement work; this application eliminates the need to remove surrounding equipment such as the upper current transformer and side columns, and the modular base 1 and tractor 4 respectively complete the lifting and transmission operations of the GIS switch 8, reducing reliance on other equipment, improving the efficiency of GIS switch 8 replacement work, and reducing overall construction costs.
[0027] In a specific embodiment of the invention, the first telescopic rod 3 is preferably an electro-hydraulic rod. The base 1 is equipped with a power supply, a controller 5, and an emergency stop switch 6. The controller 5 is electrically connected to the first telescopic rod 3, the power supply, and the emergency stop switch 6. Specifically, in this embodiment, the power supply is preferably a lithium battery housed within the base 1. The controller 5 and the emergency stop switch 6 are located at the top of the base 1. The controller 5 has a display screen that shows the battery level. The first telescopic rod 3 can be raised and lowered and stopped by the controller 5 or by a remote control. When both the controller 5 and the remote control malfunction and cannot stop the raising and lowering, pressing the emergency stop switch 6 will cut off the power to the first telescopic rod 3, immediately stopping the raising and lowering action. When the electrical control system of the first telescopic rod 3 completely fails, the raising and lowering of the first telescopic rod 3 can be operated by connecting an emergency manual pump 9, ensuring the smooth completion of the removal or installation of the GIS switch 8. Based on the above structure, the first telescopic rod 3 can be activated by the controller 5 or by the remote control. The first telescopic rod 3 can then drive the support frame 2 and the GIS switch 8 on the support frame 2 to complete the lifting operation. The pressure value of the pressure sensor 23 is wirelessly transmitted and displayed on the handheld device. By adjusting the first telescopic rod 3, the pressure value of the pressure sensor 23 is balanced, achieving the requirement of precise flange positioning. This effectively solves the problem of difficult precise docking of the GIS switch 8 flange caused by unbalanced force during traditional hoisting. It also eliminates the problem of poor synchronization of the docking surface of the GIS switch 8 affecting the sealing performance and electrical connection reliability. In other words, this application can detect and adjust the force and level of the first telescopic rod 3 in real time, solve the problem of installation deviation compensation, and improve docking accuracy.
[0028] In reality, during hoisting operations, operational errors such as manual positioning can lead to safety accidents like crushing and crushing injuries, and there is a lack of real-time status monitoring methods. To address this, the controller 5 of this application can work with sensors to monitor the operation of the first telescopic boom 3 in real time, enabling remote control operation and risk warnings, thus improving construction safety. Additionally, the emergency stop switch 6 installed on the base 1 can stop the operation of the first telescopic boom 3 in emergency situations, preventing the GIS switch 8 from colliding with other equipment due to the lifting and lowering of the first telescopic boom 3, reducing operational risks. It also prevents damage to the equipment above from excessive lifting caused by the failure of both the controller 5 and the remote control to stop the first telescopic boom 3.
[0029] Furthermore, such as Figure 3 and Figure 4 As shown, in some embodiments of this application, a connection interface 7 for connecting to the first telescopic rod 3 is fixedly provided on the base 1. Based on the above structure, when the electric lifting fails, the operator can still connect the emergency manual pump 9 through the connection interface 7. At this time, the emergency manual pump 9 is used to manually control the lifting and lowering of the first telescopic rod 3, ensuring the reliable operation of the device and improving the stability of the device operation.
[0030] It should be noted that the tractor 4 in this application is also equipped with a connection interface 7. In this embodiment of the invention, the third telescopic rod 42 of the tractor 4 is a common hydraulic rod without a power source. During use, the operator connects to a manual pump through the connection interface 7, and drives the third telescopic rod 42 to complete the lifting operation through the manual pump, thereby cooperating with other components to complete the transmission operation of the GIS switch.
[0031] Optional, such as Figure 3 As shown, the base 1 of this application includes a front adjusting frame 11, a rear adjusting frame 12, and a second telescopic rod 13 arranged sequentially along the X direction. The front adjusting frame 11 is fixedly connected to the second telescopic rod 13, and the end of the second telescopic rod 13 away from the front adjusting frame 11 is fixedly connected to the rear adjusting frame 12. Both the front adjusting frame 11 and the rear adjusting frame 12 are provided with at least one support frame 2, and both the front adjusting frame 11 and the rear adjusting frame 12 are provided with wheels 14 at their bottoms. Based on the above structure, the distance between the front adjusting frame 11 and the rear adjusting frame 12 can be changed by extending and retracting the second telescopic rod 13 during use, thereby changing the length of the entire base 1, achieving effective adaptation to GIS switches 8 of different lengths, and improving the compatibility of this tooling. Furthermore, the second telescopic rod 13 of this application can preferably be an electro-hydraulic rod driven by a power source to complete the extension and retraction, or it can preferably be a manual adjusting rod, allowing for fine adjustment through manual operation by the operator; further details are omitted here.
[0032] Optional, such as Figure 4 and Figure 5As shown, in some embodiments of this application, the support bracket 2 is arc-shaped, with a recessed mounting groove in the middle. A rubber pad 21 is provided in the mounting groove. During use, as the support bracket 2 is lifted, the GIS switch 8 falls into the mounting groove, at which point the rubber pad 21 is located between the support bracket 2 and the GIS switch 8. Based on the above structure, the rubber pad 21 can prevent the metal part of the support bracket 2 from directly contacting the surface of the GIS switch 8, thus avoiding wear on the GIS switch 8 and ensuring the structural integrity of the GIS switch 8.
[0033] Furthermore, such as Figure 4 and Figure 5 As shown, a level 22 is fixedly installed on both sides of the support frame 2. The level 22 is used to detect the horizontal state of the support frame 2, ensuring the stable loading of the GIS switch 8 by the support frame 2 and the precise connection of the flange of the GIS switch 8.
[0034] Furthermore, such as Figure 4 and Figure 5 As shown, pressure sensors 23 and force signal transmitters are fixedly installed on both sides of the support frame 2. Based on the above structure, during use, the GIS switch 8 is mounted on multiple support frames 2, and the support frames 2 are subjected to pressure from the GIS switch 8. At this time, the pressure sensors 23 can measure the pressure on the support frame 2 and transmit the data to the remote control through the force signal transmitter. The pressure on the first telescopic rod can be determined by the value on the remote control. Furthermore, since this application chooses to install pressure sensors 23 on both sides of the support frame 2, the operator can determine the force balance of each first telescopic rod by monitoring the pressure value of each first telescopic rod 3, thus avoiding the GIS switch 8 from tilting or the first telescopic rod from being overloaded and damaged due to pressure imbalance.
[0035] In addition, such as Figure 1 As shown, a ratchet cable tie 24 is fixedly installed on the support frame 2. After the GIS switch 8 is placed on the support frame 2, the operator uses the ratchet cable tie 24 to tie the GIS switch 8 to the support frame 2 together to prevent the GIS switch 8 from shifting or tipping over during transportation and to improve the stability during transmission.
[0036] For the tractor 4 of this application, in the embodiment of the present invention, the tractor 4 is preferably an electric tank vehicle, and the top of the tractor 4 is also fixedly provided with an auxiliary bracket 41 and a third telescopic rod 42. When in use, the GIS switch 8 is lifted by the auxiliary bracket 41 and the third telescopic rod 42, which can independently support one end of the GIS switch 8, so that the adjacent walking wheel 14 is suspended in the air, and it can cross obstacles such as anchor bolts or ground cable trays when moving.
[0037] It should also be noted that, from Figure 1It can be seen that both the tractor 4 and the base 1 of this application are equipped with a remote control system. When in use, the operator can remotely control the tractor 4 to drive the base 1 to move, and can also remotely control the extension and retraction of the first telescopic rod 3 and the second telescopic rod 13, the lifting of the GIS switch 8 by the support frame 2, etc., to realize remote control of the tooling and avoid the influence of complex environment on the operator.
[0038] In summary, this invention provides a GIS switch lifting and transmission fixture, including a base and a support frame. At least two support frames are sequentially arranged on the base along the X direction. Each support frame is movably connected to the base via a first telescopic rod arranged along the Z direction. The bottom of the base is equipped with wheels, and a tractor connected to the base is located at the front end of the base. Compared with the prior art, this application uses support frames to lift the GIS switch from the bottom. The tractor and base have a compact structure, effectively avoiding other equipment near the GIS switch and solving the problem of traditional hoisting equipment occupying a large construction space and being difficult to deploy. The support frame lifts the GIS switch, and the connection between the GIS switch and the base and support frame is good, preventing the GIS switch from swaying with the hoisting equipment. This effectively avoids the problem of the GIS switch's center of gravity shifting, eliminating the risk of equipment damage or personnel injury from collisions. The transmission method using a tractor to drive the base is simple, fast, and has high construction efficiency. This GIS switch lifting and transmission fixture, through modular design and hydraulic synchronous control technologies, achieves precise lifting, horizontal movement, and positioning installation of the equipment, significantly reducing reliance on large machinery and lowering construction complexity. This research not only responds to the development requirements of "reducing costs and increasing efficiency" in the power grid, but also aligns with the trend of power equipment operation and maintenance transforming towards intelligence and standardization. It has important practical significance for improving the maintenance efficiency of GIS equipment and ensuring reliable power supply from the power grid.
[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
