Description

Technical Field

[0001] The utility model relates to the technical field of GIS equipment, in particular to a GIS equipment installation auxiliary mechanism. Background Art

[0002] GIS equipment refers to gas-insulated metal-enclosed switchgear, which consists of circuit breakers, disconnectors, earthing switches, transformers, lightning arresters, busbars, connectors, and outgoing line terminals. These devices or components are all enclosed in a grounded metal casing and filled with SF6 insulating gas at a certain pressure. It is widely used in high-voltage and ultra-high-voltage fields, and is also used in the ultra-high-voltage field. Due to its excellent insulation performance and sealing, GIS equipment can ensure the safe and stable operation of the power system. Therefore, it has been widely used in substations across the country. Due to the high precision of the internal components of GIS equipment and the extremely high requirements for the environment and process during installation, GIS equipment installation auxiliary mechanisms are required to install the GIS equipment.

[0003] In the prior art, when installing GIS equipment, multiple installation foundations are set up on the ground, and then a slidable slide is installed on one of the installation foundations. The docking GIS equipment is hoisted and fixed on the other installation foundation. Then, the movable GIS equipment is hoisted by a crane and lifted above the slide. It is bolted to the slide through the mounting feet of the movable GIS equipment. Then, the docking device is installed on the docking GIS equipment and the movable GIS equipment. Finally, the slide is moved to drive the movable GIS equipment to move, so that the docking positions of the docking GIS equipment and the movable GIS equipment are aligned and docked, completing the installation of the entire GIS equipment. However, in actual work, due to the different specifications of GIS equipment, the sizes of the mounting feet at the bottom thereof are all different. As a result, the slide of each installation auxiliary mechanism can only fix and install GIS equipment of one size, reducing the scope of use of the device and the practicality of the device.

[0004] Therefore, the utility model provides a GIS equipment installation auxiliary mechanism to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a GIS equipment installation auxiliary mechanism to solve the problem that in actual work, due to the different specifications of GIS equipment, the sizes of the installation feet at the bottom thereof are all different, resulting in the slide plate of each installation auxiliary mechanism being able to fix and install GIS equipment of only one size, reducing the scope of use of the device and reducing the practicality of the device.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A GIS equipment installation auxiliary mechanism includes a slide plate, one side and the middle of the top of the slide plate are fixedly installed with a mounting seat, the interior of the mounting seat is provided with a sliding cavity and a stepped cavity from the top to the bottom, and a plurality of avoidance cavities are provided around the stepped cavity; a limit assembly, the limit assembly is used to limit the external mounting foot, and the limit assembly is connected to the avoidance cavity.

[0008] Optionally, the limiting assembly includes a blocking spring piece at one end, a connecting spring piece in the middle, and a reinforcing spring piece at the other end, and the blocking spring piece, the connecting spring piece, and the reinforcing spring piece are an integrated structure.

[0009] Optionally, one end of the blocking spring away from the connecting spring is fixedly connected to the top of the corresponding avoidance cavity, and one end of the reinforcing spring away from the connecting spring is fixedly connected to the middle of the corresponding avoidance cavity.

[0010] Optionally, an arc-shaped plate is fixedly connected to the interior of the mounting seat on all sides of the sliding cavity, and a buffer cavity is opened inside the mounting seat on all sides of the arc-shaped plate.

[0011] Optionally, one side of the buffer cavity close to the corresponding arc-shaped plate is arc-shaped, and the other side of the buffer cavity is wavy with multiple inward concavities.

[0012] Optionally, the stepped cavity is divided into three sections, namely cavity No. 1, cavity No. 2 and cavity No. 3 from top to bottom, and the area decreases from top to bottom.

[0013] Optionally, the avoidance cavity is distributed around the first cavity and the second cavity, and the avoidance cavity is a groove protruding outward.

[0014] Optionally, the connection between the No. 1 cavity and the No. 2 cavity and the connection between the No. 2 cavity and the No. 3 cavity are both arc surfaces.

[0015] Optionally, the area of the bottom of the sliding cavity is larger than the area of the top of the stepped cavity, and the connection between the sliding cavity and the stepped cavity is a curved surface.

[0016] Optionally, the cross section of the mounting seat is trapezoidal, and the top of the mounting seat is horizontal due to the sliding plate.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting the stepped cavity and the limit assembly, the setting of the three cavities of the stepped cavity allows installation feet of different specifications to enter smoothly and stay in the appropriate position, which is convenient for the installation and fixation of installation feet of different specifications. The limit assembly can push the installation foot so that the installation foot slides smoothly into the cavity of the appropriate specification. The cooperation of the stepped cavity and the limit assembly realizes the installation and fixation of GIS equipment of different specifications, improves the stability and efficiency of the installation process, makes the installation of GIS equipment simpler and faster, and increases the practicality of the device.

[0019] By arranging blocking shrapnel and reinforcing shrapnel inside the limit assembly, the blocking shrapnel will give the mounting foot a certain resistance, so that the mounting foot slides into the cavity of the corresponding specification, and it is convenient to adjust the mounting cavity of the mounting foot through the blocking shrapnel, so that the mounting foot is installed in the cavity of the corresponding specification, thereby realizing the installation of mounting feet of different specifications. The reinforcing shrapnel supports the reinforced blocking shrapnel to prevent the mounting foot from squeezing the blocking shrapnel and entering cavities of different specifications, thereby increasing the installation accuracy of the mounting foot and avoiding the occurrence of installation errors. By arranging the avoidance cavity, it is convenient to store the limiting assembly after installation, and further assist in clamping and fixing the mounting foot to complete the pre-fixation of the mounting foot, which not only improves the stability and safety of the installation process, but also simplifies the installation steps and improves work efficiency.

[0020] By setting up the sliding cavity, the hoisting installation of the mounting foot can be pre-positioned, the sliding area of the mounting foot is increased, and the situation where the mounting foot is difficult to align with the mounting hole when hoisting the GIS equipment is avoided. The jamming or obstruction that may occur in the traditional installation process is eliminated, the installation steps are greatly simplified, and work efficiency is improved. The arc surface design at the connection between the sliding cavity and the stepped cavity further reduces the resistance of the mounting foot during movement, ensuring the smoothness of the installation process.

[0021] By providing a buffer cavity, the buffer cavity can buffer the collision between the hoisted mounting feet and the curved plate during installation. By dispersing and absorbing these forces, damage to the GIS equipment itself and the installation auxiliary mechanism is effectively reduced. The wavy design makes the buffer cavity have excellent shock absorption performance, further buffering the force, ensuring the stability of the GIS equipment, and preventing the curved plate from retracting too much, resulting in excessive force during rebound, pushing the mounting feet to swing, so that the mounting feet are tightly attached to the curved plate for sliding installation. The cooperation between the buffer cavity and the curved plate plays an effective buffering and protective role during the installation of the GIS equipment, improving the stability and safety of the installation process.

[0031] The following describes in detail a GIS equipment installation auxiliary mechanism and its use method provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known technologies.

[0036] like Figures 1 to 5 As shown, an embodiment of the present invention provides a GIS equipment installation auxiliary mechanism, including a slide plate 1, a mounting seat 2 is fixedly installed on one side and the middle of the top of the slide plate 1, and a sliding cavity 3 and a step cavity 4 are sequentially opened inside the mounting seat 2 from the top to the bottom. The mounting seat 2 is fixedly connected to the sliding cavity 3 on all sides thereof, and a buffer cavity 6 is opened on all sides thereof on the curved plate 5. The side of the buffer cavity 6 close to the corresponding curved plate 5 is arc-shaped, and the other side of the buffer cavity 6 is a wave-shaped inward concave shape at multiple locations. The cross-section of the mounting seat 2 is trapezoidal, and the top of the mounting seat 2 is horizontal against the slide plate 1.

[0037] The slide plate 1 is slidably arranged on the top of the external foundation, and the GIS equipment is hoisted by a crane so that the mounting feet on both sides of the bottom are respectively located above the two mounting seats 2, thereby lowering the height of the GIS equipment so that the mounting feet enter the corresponding mounting seats 2, and then enter the sliding cavity 3 and touch the arc-shaped plate 5 made of high-strength elastic metal. The impact and vibration during the contact are buffered by the buffer cavity 6, which effectively reduces the damage to the GIS equipment by dispersing and absorbing these forces. The buffer cavity 6 has excellent shock absorption performance due to the multiple inwardly concave wavy shapes on the inside. The buffer cavity 6 is divided into two sections by the inner wavy shapes. The curvature of the cloth disperses and absorbs the stress of the collision of the mounting feet, further assisting in buffering the impact, and when the mounting feet squeeze and push the curved plate 5, the curved plate 5 is supported by the inward concave protrusions to prevent the curved plate 5 from retracting too much, resulting in excessive force when rebounding, pushing the mounting feet to swing, increasing the stability of the installation, and allowing the mounting feet to slide against the curved plate 5. Through the cooperation of the curved plate 5 and the buffer cavity 6, an effective buffering and protection effect is played during the installation process, which not only improves the stability of the installation process, but also ensures the safety of the GIS equipment during installation and avoids damage to the GIS equipment.

[0038] like Figures 3 to 5 As shown, a number of avoidance cavities 7 and a limit assembly 8 are provided around the stepped cavity 4. The limit assembly 8 is used to limit the external mounting foot. The limit assembly 8 is connected to the avoidance cavity 7. The limit assembly 8 includes a blocking spring 801 at one end, a connecting spring 802 in the middle and a reinforcing spring 803 at the other end. The blocking spring 801, the connecting spring 802 and the reinforcing spring 803 are an integrated structure. The end of the blocking spring 801 away from the connecting spring 802 is fixedly connected to the top of the corresponding avoidance cavity 7. The stepped cavity 4 is divided into three sections, which are cavity No. 1 401, cavity No. 2 402 and cavity No. 3 403 from top to bottom. The area decreases from top to bottom. The area of the bottom of the sliding cavity 3 is larger than the area of the top of the stepped cavity 4. The connection between the sliding cavity 3 and the stepped cavity 4 is an arc surface.

[0039] The mounting foot slides from the sliding cavity 3 into the stepped cavity 4. The arc surface design at the connection makes it easier for the mounting foot to slide into the stepped cavity 4 along the arc surface, making the installation process smoother and reducing the heat and wear caused by friction. The limiting component 8 is made of high-strength elastic metal. The mounting foot enters the No. 1 cavity 401 of the stepped cavity 4. When the specification of the mounting foot does not match the No. 1 cavity 401, the area of the mounting foot will be smaller than the area of the No. 1 cavity 401. Therefore, only one side of the mounting foot will contact the outer arc surface of the blocking shrapnel 801. Because the GIS equipment is hoisted, a force far less than the weight of the GIS equipment is used to push the GIS equipment. Therefore, the blocking shrapnel 801 can push the mounting foot through the outer arc surface to block the mounting foot. It falls into the No. 1 cavity 401, so that the mounting foot slides into the No. 2 cavity 402, ensuring that the mounting foot of the GIS equipment can be accurately fixed at a position of appropriate specifications. The elasticity of the blocking spring piece 801 is enhanced by the reinforcement spring piece 803, so that the blocking spring piece 801 will not be easily deformed and retracted due to the squeezing of the mounting foot. The limit assembly 8 forms a stable structure by connecting the spring piece 802, which can ensure the overall stability of the limit assembly 8, so as to ensure the limit control of the mounting foot and ensure that it can smoothly slide into the cavity of appropriate specifications, so that the device can install and fix mounting feet of different specifications, and make the installation work of GIS equipment more simple and quick, thereby increasing the practicality of the device.

[0040] like Figures 1 to 5 As shown, the end of the reinforcing spring piece 803 away from the connecting spring piece 802 is fixedly connected to the middle of the corresponding avoidance cavity 7. The avoidance cavity 7 is distributed around the No. 1 cavity 401 and the No. 2 cavity 402. The avoidance cavity 7 is a groove protruding outward. The connection between the No. 1 cavity 401 and the No. 2 cavity 402 and the connection between the No. 2 cavity 402 and the No. 3 cavity 403 are all arc surfaces.

[0041] The mounting foot continues to slide downward, and when it slides into the cavity of suitable specifications, the area of the mounting foot is adapted to the cavity, and the bottom of the mounting foot respectively contacts the blocking springs 801 on all sides. At this time, the weight of the GIS equipment will act on the blocking spring 801, causing the blocking spring 801 to deform and retract. The concave setting of the connecting spring 802 makes it possible for the blocking spring 801 to deform inward and retract into the avoidance cavity 7 when the blocking spring 801 is deformed, thereby preventing the blocking spring 801 from folding outward and thereby preventing the blocking spring 801 from folding outward. The mounting foot is blocked and then fixed inside the adapted cavity. The mounting foot is clamped and pre-fixed by the blocking springs 801 around it to prevent it from being offset or loosened, thereby achieving precise positioning of the mounting foot and improving the stability and efficiency of the installation process, making the installation work faster. The mounting foot is then fixed by bolts and screw holes reserved inside the stepped cavity 4 to complete the fixation of the GIS device. After the docking device is installed on the GIS device, slide the slide 1 to dock the GIS device with another GIS device and complete the docking fixation.

[0042] The working principle of the present invention is that the slide plate 1 is slidably arranged on the top of the external foundation, and the GIS equipment is hoisted by a crane so that the mounting feet on both sides of the bottom are respectively located above the two mounting seats 2, and the height of the GIS equipment is lowered so that the mounting feet enter the corresponding mounting seats 2, and the mounting feet enter the sliding cavity 3, and the impact of the collision is buffered by the buffer cavity 6 and the arc plate 5, and then the mounting feet slide into the stepped cavity 4. When the specifications of the mounting feet do not fit the current cavity, the blocking spring piece 801 and the reinforcement spring piece 803 cooperate to block the mounting feet, so that the mounting feet The foot slides downward. When the specifications of the mounting foot are adapted to the current cavity, the bottom of the mounting foot respectively contacts and squeezes the blocking springs 801 on the surrounding areas, and drives the connecting springs 802 and the reinforcing springs 803 to deform and retract into the avoidance cavity 7. Then the mounting foot contacts the inside of the adapted cavity, and the mounting foot is fixed with bolts through the screw holes reserved in the stepped cavity 4 to complete the fixation of the GIS equipment. After installing the docking device on the GIS equipment, slide the slide 1 to dock the GIS equipment with another GIS equipment, and complete the docking and fixation.

[0043] The above slide plate 1 and GIS equipment in this utility model are both disclosed in the prior art and will not be described in detail here.

[0044] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
