Description

Technical Field

[0001] This utility model relates to the field of power transmission equipment construction technology, and in particular to an auxiliary device for positioning high-voltage switchgear. Background Technology

[0002] Currently, high-voltage switchgear (HGIS) is widely used in ultra-high voltage substations such as 330kV and 500kV, as well as medium-high voltage substations such as 110kV. With the advancement of smart grid construction, the intelligence level of HGIS equipment is continuously improving, and its placement technology is also constantly developing to adapt to the needs of smart grids.

[0003] Most existing HGIS placement methods adopt traditional hoisting installation, which often uses large cranes (such as crawler cranes and truck cranes). The hoisting process is often limited by the operating space of the hoisting equipment (slewing radius, ground bearing capacity), especially in expansion projects (the original site is already in use, the busbar above the equipment is energized, and the normal equipment hoisting safety distance is insufficient, which seriously affects the equipment hoisting). During the hoisting process, collisions with surrounding structures (supports, installed equipment) are likely to occur, resulting in equipment damage.

[0004] During the hoisting process, the equipment is affected by wind and boom sway, resulting in positioning deviations that require repeated adjustments. Even with laser positioning assistance, fine-tuning after landing relies on manual or mechanical lifting, which is inefficient and has limited accuracy. Utility Model Content

[0005] The main purpose of this utility model is to propose a positioning auxiliary device for high-voltage switchgear, which aims to solve the technical problems of positioning deviation caused by wind force and boom swing during hoisting, requiring repeated adjustments, and even with laser positioning assistance, fine-tuning after landing still relies on manual or mechanical lifting, resulting in low efficiency and limited accuracy.

[0006] To achieve the above objectives, this utility model proposes a high-voltage switchgear positioning auxiliary device. The high-voltage switchgear positioning auxiliary device is installed on one side of the mounting base of the high-voltage switchgear, and a mounting position is formed on the mounting base. The high-voltage switchgear positioning auxiliary device includes:

[0007] A guide member, which is placed on a hardened surface, with one end of the guide member extending to one side of the mounting base;

[0008] A sliding assembly, slidably mounted on the guide member, wherein a support platform is formed on the top of the sliding assembly, and the high-voltage switchgear is placed on the support platform; and,

[0009] A drive assembly is mounted on the side of the sliding assembly away from the mounting base. The drive end of the drive assembly is connected to the sliding assembly. The drive assembly can drive the sliding assembly to slide the high-voltage switchgear along the guide to one side of the mounting base, and the drive assembly can drive the high-voltage switchgear to slide from the support platform to the mounting position.

[0010] In one embodiment, the sliding component includes:

[0011] A support plate, the top surface of which forms the support platform; and,

[0012] A sliding member is installed at the bottom of the support plate and is slidable along the guide member.

[0013] In one embodiment, the top surface elevation of the support platform is the same as the top surface elevation of the mounting position.

[0014] In one embodiment, the slider has a first groove that is adapted to and slidably engaged with the guide.

[0015] In one embodiment, a first lubricating oil film is formed between the first groove and the guide member.

[0016] In one embodiment, the driving component includes:

[0017] Mounting base, which is slidably mounted on the guide member;

[0018] A diagonal brace is installed on the mounting base and extends diagonally downward along the extension direction of the guide member. A base plate is provided at the bottom of the diagonal brace, and the base plate can abut against the hardened ground.

[0019] A driving element, the driving element being mounted on the mounting base; and,

[0020] A telescopic component is mounted on the driving component and is detachably connected to the sliding assembly. The driving component can drive the telescopic component to push the sliding assembly to slide along the guide.

[0021] In one embodiment, the mounting base has a second groove that slides in conjunction with the guide member.

[0022] In one embodiment, a second lubricating oil film is formed between the second groove and the guide member.

[0023] In one embodiment, the bottom surface of the base plate has a plurality of spaced friction protrusions.

[0024] In one embodiment, there are multiple guide members, which are spaced apart and each guide member extends to one side of the mounting base at the same end. The sliding component is slidably engaged with all the guide members, and the number of the driving component is the same as that of the guide members and they are arranged in a one-to-one correspondence.

[0025] The technical solution of this utility model, by setting up a guide component, a sliding component, and a driving component, allows the guide component to be placed on a hardened ground during use. One end of the guide component extends to one side of the mounting base.

[0037] This utility model proposes an auxiliary device for positioning high-voltage switchgear.

[0038] Please see Figures 1 to 4In one embodiment of this utility model, a high-voltage switchgear 100 positioning auxiliary device is installed on one side of a mounting base 200 of the high-voltage switchgear 100, and a mounting position is formed on the mounting base 200. The high-voltage switchgear 100 positioning auxiliary device includes a guide 300, a sliding assembly 400, and a driving assembly 600. The guide 300 is placed on a hardened ground, and one end of the guide 300 extends to one side of the mounting base 200. The sliding assembly 400 is slidably mounted on the guide 300. 300, and a support platform 500 is formed on the top of the sliding assembly 400. The high-voltage switchgear 100 is placed on the support platform 500. The drive assembly 600 is installed on the side of the sliding assembly 400 away from the mounting base 200. The drive end of the drive assembly 600 is connected to the sliding assembly 400. The drive assembly 600 can drive the sliding assembly 400 to slide the high-voltage switchgear 100 along the guide 300 to one side of the mounting base 200. The drive assembly 600 can also drive the high-voltage switchgear 100 to slide from the support platform 500 to the mounting position.

[0039] In the high-voltage switchgear 100 positioning auxiliary device of this application, the guide member 300 is placed on a hardened ground, with one end extending to one side of the mounting base 200, forming a continuous guide path from the ground to the mounting base 200. The sliding assembly 400 is slidably mounted on the guide member 300 and supports the high-voltage switchgear 100 through the support platform 500 formed on its top. The drive assembly 600 is mounted on the side of the sliding assembly 400 away from the mounting base 200. Through its drive end connected to the sliding assembly 400, it can provide a precise and controllable driving force, enabling the sliding assembly 400 to drive the high-voltage switchgear 100 to slide smoothly along the guide member 300 to one side of the mounting base 200, and finally drive the high-voltage switchgear 100 to slide precisely from the support platform 500 to the installation position.

[0040] In the traditional installation of high-voltage switchgear 100, the equipment is usually moved to the installation position by hoisting. However, during hoisting, it is easily affected by external factors such as wind and boom sway, resulting in positioning deviations that require repeated adjustments. Even with laser positioning assistance, fine-tuning after landing still relies on manual or mechanical lifting, which is inefficient and has limited accuracy. In contrast, the high-voltage switchgear 100 positioning assistance device of this application provides a precise guiding path through the guide component 300, the sliding component 400 slides stably on the guide component 300, and the drive component 600 provides controllable driving force, enabling the high-voltage switchgear 100 to move precisely along the predetermined path and be installed in place. This effectively avoids the positioning deviation problem in the traditional hoisting process, eliminates the need for repeated adjustments, and greatly improves installation efficiency and accuracy.

[0041] In this embodiment, by providing a guide 300, a sliding assembly 400, and a drive assembly 600, in use, the guide 300 is placed on a hardened surface, with one end of the guide 300 extending to one side of the mounting base 200. The sliding assembly 400 is slidably mounted on the guide 300, and a support platform 500 is formed on the top of the sliding assembly 400. The high-voltage switchgear 100 is placed on the support platform 500. The drive assembly 600 is mounted on the side of the sliding assembly 400 away from the mounting base 200, and the drive end of the drive assembly 600 is connected to the sliding assembly 400. The drive assembly 600 can drive the sliding assembly 400 to slide the high-voltage switchgear 100 along the guide 300 to one side of the mounting base 200. The drive assembly 600 can also drive the high-voltage switchgear 100 to slide from the support platform 500 to the mounting position. This allows the high-voltage switchgear 100 to be installed without the need for hoisting, avoiding the impact of boom swing during hoisting operations, improving positioning accuracy, eliminating the need for repeated adjustments, and ensuring installation accuracy.

[0042] In one embodiment, the sliding assembly 400 includes a support plate 410 and a slider 420. The top surface of the support plate 410 forms a support platform 500, and the slider 420 is mounted on the bottom of the support plate 410 and can slide along the guide 300.

[0043] Specifically, the support plate 410 has a flat plate structure, and its upper surface forms a support platform 500 for supporting the high-voltage switchgear 100. The support plate 410 is made of a material with sufficient strength, such as steel plate or alloy plate, to ensure that it can withstand the weight of the high-voltage switchgear 100 without deformation. The surface of the support platform 500 may be provided with anti-slip texture or coated with anti-slip material to increase the friction with the bottom of the high-voltage switchgear 100 and prevent the high-voltage switchgear 100 from sliding or shifting during movement.

[0044] The sliding component 420 is installed at the bottom of the support plate 410 and can be fixed with bolts to ensure a firm and reliable connection. The sliding component 420 cooperates with the guide component 300 and can slide smoothly along the guide component 300. When the drive assembly 600 drives the sliding assembly 400 to move, the sliding component 420 slides along the guide component 300, driving the support plate 410 and the high-voltage switchgear 100 on the support platform 500 to move together, realizing the smooth transport of the high-voltage switchgear 100.

[0045] The support plate 410 serves as a support platform, providing a stable support surface for the high-voltage switchgear 100. The cooperation between the sliding member 420 and the guide member 300 ensures the accuracy of the movement direction and the smoothness of the movement process. This cooperation effectively solves the positioning deviation problem caused by external factors such as wind force and boom sway during traditional hoisting, eliminating the need for repeated adjustments and improving installation efficiency and accuracy.

[0046] To further clarify, the top elevation of the support platform 500 is the same as the top elevation of the installation position.

[0047] In one embodiment, a first groove 430 is formed on the slider 420 to be adapted to and slidably engaged with the guide 300.

[0048] Specifically, a first groove 430 is disposed at the bottom of the slider 420, and its shape and size are adapted to the outer shape of the guide 300, allowing the slider 420 to be stably fitted onto the guide 300 and slide along it. An appropriate gap is maintained between the inner wall of the first groove 430 and the outer surface of the guide 300, ensuring smooth sliding while preventing the slider 420 from shaking or shifting during sliding. The inner wall of the first groove 430 may be provided with a wear-resistant material or coating to reduce friction with the guide 300 and extend its service life.

[0049] In one embodiment, a first lubricating oil film 440 is formed between the first groove 430 and the guide member 300.

[0050] In this embodiment, by forming a first lubricating oil film 440 between the first groove 430 and the guide member 300, the present invention can improve the sliding effect of the sliding component 400 and reduce friction loss during use.

[0051] In one embodiment, the drive assembly 600 includes a mounting base 610, a diagonal brace 620, a drive member 630, and a telescopic member 640. The mounting base 610 is slidably mounted on the guide member 300. The diagonal brace 620 is mounted on the mounting base 610 and extends obliquely downward along the extension direction of the guide member 300. A base plate is provided at the bottom of the diagonal brace 620, which can abut against the hardened ground. The drive member 630 is mounted on the mounting base 610, and the telescopic member 640 is mounted on the drive member 630. The telescopic member 640 is detachably connected to the sliding assembly 400. The drive member 630 can drive the telescopic member 640 to push the sliding assembly 400 to slide along the guide member 300.

[0052] Specifically, the mounting base 610 is made of metal and has sufficient strength and rigidity to withstand various forces generated during the driving process. The bottom of the mounting base 610 has a sliding groove that matches the guide member 300, allowing it to slide smoothly along the guide member 300. The mounting base 610 has mounting holes and a mounting platform for fixing the diagonal brace 620 and the drive member 630, ensuring a firm and reliable connection between all components.

[0053] The diagonal brace 620 is fixedly mounted on the mounting base 610, extending diagonally downwards along the extension direction of the guide member 300. The diagonal brace 620 employs a triangular structure, providing excellent support and stability. A base plate is provided at the bottom of the diagonal brace 620, abutting against the hardened ground to form a stable support point, preventing the mounting base 610 from tilting or shifting during operation. An anti-slip pad can be installed on the bottom surface of the base plate to increase friction with the ground and further improve stability.

[0054] The drive component 630 is mounted on the mounting base 610 and can be in the form of a hydraulic cylinder, pneumatic cylinder, or electric actuator. The drive component 630 receives operating commands through the control system and generates thrust or pull force. The telescopic component 640 is mounted on the output end of the drive component 630 and can extend or retract with the movement of the drive component 630. The telescopic component 640 is detachably connected to the sliding assembly 400, for example, via a quick connector or pin, for easy installation and removal.

[0055] It should be specifically and clearly stated that a second groove 670 is formed on the mounting base 610, which slides in conjunction with the guide member 300.

[0056] In one embodiment, a second lubricating oil film 680 is formed between the second groove 670 and the guide member 300.

[0057] In this embodiment, by forming a second lubricating oil film 680 between the second slide groove 670 and the guide member 300, the present invention can slide along the guide member 300 under the drive of the sliding component 400 during use, thereby improving the flexibility of the present invention.

[0058] In one embodiment, the bottom surface of the base plate has a plurality of spaced friction protrusions.

[0059] In this embodiment, by setting multiple friction protrusions, the present invention can enhance the friction effect between the base plate and the hardened ground during use.

[0060] In one embodiment, there are multiple guide members 300, which are spaced apart and each guide member 300 extends to one side of the mounting base 200 at the same end. The sliding component 400 is slidably engaged with all the guide members 300, and the number of the driving component 600 is the same as that of the guide members 300 and they are set in a one-to-one correspondence.

[0061] In this embodiment, by providing multiple guide members 300, the stability of the present invention can be improved during use.

[0062] It should be specifically and clearly stated that the guide 300 in this embodiment is preferably a steel rail.
