Description

Technical Field

[0001] The invention belongs to the technical field related to auxiliary installation of transformer substations, and in particular relates to an auxiliary positioning device for butt joint of pipeline flanges of GIS equipment used in transformer substations. Background Art

[0002] Substation refers to the place in the power system where voltage and current are transformed, electric energy is received and distributed. The substation in the power plant is a step-up substation, which is used to step up the electric energy generated by the generator and feed it into the high-voltage power grid. Among them, GIS equipment is a type of substation, also known as gas-insulated switchgear, which is mainly composed of circuit breakers, disconnectors, grounding switches, current transformers, voltage transformers, lightning arresters, busbars, connectors and outgoing terminals. These devices or components are all enclosed in a metal grounded casing, which is filled with SF6 insulating gas at a certain pressure. In order to facilitate the installation of the sealed pipe in the pipeline on the GIS equipment, the flange at the end of the sealed pipe needs to be installed on the pipe flange on the GIS equipment. According to the existing public document CN107813263B, when installing the sealed pipe, a corresponding docking auxiliary positioning device needs to be used.

[0003] Therefore, when installing the pipe flange on the GIS equipment, most of them use lifting equipment to lift the pipe flange, and then manually support the pipe flange to align the pipe flange with the pipe port position on the GIS equipment. However, this method cannot ensure the stability of the position of the pipe flange. During the lifting and transfer process, the rotation amplitude is easy to be too large, which will cause the pipe flange to contact with the construction personnel. At the same time, the shaking of the pipe flange is not easy to control the calibration between the pipe flange and the pipe port position of the GIS equipment. At the same time, after the pipe flange and the GIS equipment are abutted, the position of the pipe flange is easily deviated during the installation process, which will cause the installation hole on the pipe flange to be inconsistent with the installation hole position on the GIS equipment. The pipe flange is large in size, so it is impossible to adjust the pipe flange, so that the pipe flange cannot be installed quickly. To this end, we provide a pipe flange docking auxiliary positioning device for GIS equipment in substations to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Fig.11 and Fig.13 This is the first embodiment of the present invention, which provides an auxiliary positioning device for the flange connection of GIS equipment in a substation. The compression strip 205 and the arc-shaped pressure strip 204 are used in conjunction with each other to facilitate the positioning of the flange assembly 500. At the same time, the linkage strip 305 controls the vacuum ball 304b to vacuum the suction cup 301a, so that the suction cup 301a is adsorbed on the flange assembly 500, and the flange assembly 500 can be rotated and fine-tuned.

[0039] Specifically, the linkage conveying assembly 100 includes a U-shaped frame 101 that opens upward, a transverse plate 104 fixed at one end of the U-shaped frame 101, and a lifting plate 105 fixed at the other end of the U-shaped frame 101. The positioning assembly 200 includes a support plate 201 that slides on the upper end surface of the transverse plate 104, arc-shaped pressure strips 204 located on both sides of the support plate 201, and a moving strip 202 fixed at one end of the support plate 201 and connected to the upper end surface of the transverse plate 104. The rotation fine adjustment assembly Component 300, including an air disk 301 located just above the moving bar 202, a plurality of suction cups 301a fixed to the side of the air disk 301 and distributed in a circular array, and an air cylinder 303 fixed to the other side of the air disk 301, a size correction component 400, including a correction plate 401 located between the lifting plate 105 and the horizontal plate 104, a flange component 500 connected to the upper surface of the horizontal plate 104, and the upper surface of the correction plate 401 is flush with the upper surface of the horizontal plate 104;

[0040] Through the arrangement and use of the above-mentioned structure, the flange assembly 500 is set on the support plate 201, and the linkage conveying assembly 100 is controlled to work, thereby controlling the positioning assembly 200 to drive the flange assembly 500 to move in the direction of the lifting plate 105, so that the flange assembly 500 is connected with the position of the pipeline port of the GIS equipment. At the same time, when it is necessary to control the flange assembly 500 to perform fine-tuning rotation, the suction cup 301a on the end face of the gas disk 301 is abutted against the pipe surface of the flange assembly 500. At this time, a vacuum treatment is performed to make the suction cup 301a and the flange assembly 500 adsorbed, and then the flange assembly 500 can be controlled to rotate, so as to perform fine-tuning on the flange assembly 500.

[0041] according to Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.11The upper end surface of the support plate 201 is provided with a plurality of notches 201b which are linearly arranged left and right, and compression strips 205 are arranged inside the notches 201b. The arc-shaped pressure strips 204 on each side of the support plate 201 correspond to the compression strips 205 one by one. A suction ball 304b is arranged inside the air cylinder 303, and an inclined linkage strip 305 is arranged at the outer end of the air cylinder 303. A rotating opening 305b is arranged at one end of the linkage strip 305, and a rotating rod 305c is fixed on the side wall of the linkage strip 305 located inside the rotating opening 305b. A shaft rod 304 is fixed on the surface side of the suction ball 304b, and a rotating cylinder 304a sleeved on the rotating rod 305c is fixed on the other end of the shaft rod 304;

[0042] When the above-mentioned structure is used, after the flange assembly 500 is placed on the upper end surface of the support plate 201, the support plate 201 will squeeze the compression strip 205, so that the compression strip 205 will move downward, and through a series of structures, the arc-shaped pressure strip 204 will be controlled to move toward the flange assembly 500, and the arc-shaped pressure strip 204 will be squeezed on the flange assembly 500, so as to ensure the stability of the position of the flange assembly 500;

[0043] When the suction cup 301a is in contact with the flange assembly 500, the gas in the suction cup 301a needs to be vacuumed. Therefore, the linkage bar 305 is controlled to rotate toward the surface side of the gas cylinder 303, whereby the linkage bar 305 will drive the shaft 304 to move outward inside the gas cylinder 303, and thereby drive the vacuum ball 304b to move inside the gas cylinder 303. Since the vacuum ball 304b is closely connected to the inner wall of the gas cylinder 303, the interior of the suction cup 301a is vacuumed. At this time, the linkage bar 305 is controlled to rotate along the circumference of the gas cylinder 303, whereby the linkage bar 305 drives the gas cylinder 303 and the suction cup 301a to rotate, and thereby slightly drives the flange assembly 500 to rotate, so as to facilitate fine-tuning of the flange assembly 500 and ensure that the mounting hole on the flange assembly 500 corresponds to the mounting hole of the pipeline port of the GIS equipment.

[0044] Further, according to Figure 3 and Figure 4As can be seen, a sliding opening 104a is provided on the upper end surface of the horizontal plate 104, and a movable plate 202a that is clearance-matched with the sliding opening 104a is fixed to the portion of the lower surface of the moving bar 202 away from the lifting plate 105. When the movable plate 202a is moved by the lead screw 102, the movable plate 202a will move along the sliding opening 104a, and then the movable plate 202a will drive the moving bar 202 to move on the upper end surface of the support plate 201, thereby pushing the support plate to move in the direction of the lifting plate 105. A vertical plate 104b is fixed to the portion of the lower surface of the moving bar 202 close to the lifting plate 105, and a lead screw 102 is rotatably arranged between the vertical plate 104b and the U-shaped frame 101, which is located directly below the horizontal plate 104, and a lead screw 102 that is clearance-matched with the lead screw 104a is fixed to the side wall of the U-shaped frame 101. 02 transmission connected to the motor 103, the movable plate 202a is rotatably connected to the ball block on the screw 102 through the rotating ring 202b fixed on the side wall. When it is necessary to control the support plate 201 to slide along the upper end surface of the transverse plate 104, the motor 103 can be controlled to rotate forward, and then the motor 103 directly drives the screw 102 to rotate, thereby the screw 102 controls the ball seat on its surface to drive the movable plate 202a to move, thereby driving the moving bar 202 to move, and thereby controlling the support plate 201 to drive the flange assembly 500 to move to abut against the pipeline port position of the GIS equipment. When the motor 103 reverses, it will drive the movable plate 202a to move in the direction of the motor 103, thereby driving the support plate 201 to slide in the direction away from the lifting plate 105.

[0045] It should be noted that when installing the flange assembly 500, it is necessary to move the port position of the GIS equipment pipeline to the upper end surface position of the lifting plate 105 to ensure that the flange assembly 500 and the GIS equipment pipeline are consistent in the left and right directions, and the motor 103 used needs to be connected to the external power supply and control structure to ensure the operation of the control motor 103. At the same time, the interior of the suction cup 301a is connected to the interior of the air cylinder 303 to ensure that the vacuum ball 304b can stably evacuate air. At the same time, the flange assembly 500 consists of a flange plate and a pipeline with the other end closed.

[0046] Example 2

[0047] See also Figure 3 , Figure 4 and Fig.13 On the basis of Example 1, this embodiment is applicable to flanges of different diameters by using a correction plate 401 and a correction spring 403 in combination.

[0048] Specifically, the side walls of the vertical plate 104b and the U-shaped frame 101 opposite to each other are provided with adjustment ports 106, and a limiting rod 107 fixedly connected to the vertical plate 104b and the side walls of the U-shaped frame 101 is provided inside each adjustment port 106, and L-shaped plates 402 sliding inside the adjustment ports 106 are fixed at two parts of the lower end surface of the correction plate 401, and the L-shaped plate 402 is sleeved on the limiting rod 107 through the limiting hole 402a provided on the side wall, and a correction spring 403 sleeved on the limiting rod 107 is fixed at the bottom of the L-shaped plate 402;

[0049] By setting up and using the above-mentioned structure, the flange assembly 500 is placed on the upper end surface of the support plate 201, and the flange plate of the end surface of the flange assembly 500 needs to be connected with the end surface of the support plate 201, and then the support plate 201 is connected with the end surface of the correction plate 401. At the same time, the support plate 201 will move downward after being squeezed, so that the support plate 201 drives the L-shaped plate 402 to move downward inside the adjustment port 106, and will compress the correction spring 403. When the correction plate 401 is not squeezed, the correction spring 403 pushes the L-shaped plate 402 to move upward, and thereby controls the correction plate 401 to reset. At the same time, the limiting rod 107 is in the limiting hole 402a, so as to limit the correction spring 403 and avoid excessive bending of the correction spring 403.

[0050] Example 3

[0051] See also Figure 3 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 On the basis of Example 1, this embodiment uses a pushing rod 206 and a return spring 206b to facilitate the control of the rotation and return of the arc-shaped pressure strip 204.

[0052] Specifically, curved cylinders 201a are fixed at positions corresponding to the arc-shaped pressure strips 204 on both side walls of the support plate 201, curved holes 201d connected to the inside of the curved cylinder 201a are opened on both side walls of the support plate 201, the curved cylinder 201a and the adjacent recess 201b are connected through a circular hole 201e opened in the support plate 201, and extrusion rings 201f are fixed at positions where the curved cylinder 201a and the curved holes 201d are connected, and the upper end surface of the arc-shaped pressure strip 204 is rotatably provided with a flange assembly 50 0 abuts against the friction tooth block 204a, the lower end surface of the compression strip 205 is fixed with two rubber rods 205a respectively passing through the corresponding circular holes 201e, the other end of the rubber rod 205a is fixed with a rubber block 205b located in the inner position of the curved hole 201d, and the interior of the extrusion ring 201f is slidably provided with a pushing rod 206, one end of the pushing rod 206 is fixed with a piston block 206a located in the curved hole 201d and connected to the rubber block 205b, and the other end of the pushing rod 206 is fixed with a piston block 206a slidably provided in the curved hole 201d and connected to the rubber block 205b. A pushing block 206c is arranged inside the curved cylinder 201a, a return spring 206b is fixed on the side wall of the piston block 206a and is in contact with the extrusion ring 201f, an arc-shaped opening 201a-1 is provided on the surface side of the curved cylinder 201a corresponding to the arc-shaped pressure strip 204 and is connected to the inside of the curved cylinder 201a, a sleeve 204b is fixed to the lower end of the arc-shaped pressure strip 204, and a pressure block 204c is arranged directly below the sleeve 204b and slides inside the curved cylinder 201a. A connecting strip 204c-1 is fixed between the two sides of the support plate 201, which slides inside the arc-shaped opening 201a-1. Positioning rods 201c are arranged on both sides of the support plate 201. The positioning rods 201c are fixedly connected to the support plate 201 through the mounting plates 201c-1 fixed at the ends. The sleeves 204b are sleeved on the corresponding positioning rods 201c. The middle part of the inner side of the sleeves 204b is provided with a ring opening 204b-1. The surface side of the positioning rod 201c is fixed with a plurality of convex rings 201c-2 respectively located inside the ring opening 204b-1.

[0053] By setting and using the above-mentioned structure, when the pipe on the flange assembly 500 squeezes the compression strip 205, the compression strip 205 will drive the rubber rod 205a to move inside the circular hole 201e, and control the rubber block 205b to push the piston block 206a to slide along the curved hole 201d, so that the piston block 206a will push the pressure block 204c to slide inside the curved cylinder 201a through the pushing rod 206 and the pushing block 206c, so that the curved cylinder 201a drives the sleeve 204b to rotate on the surface side of the positioning rod 201c through the connecting strip 204c-1, and thereby controls the arc strip 204 to rotate to abut against the surface side of the pipe of the flange assembly 500, and at the same time the piston block 206a moves to the position of the squeezing ring 201f. When moving, the piston block 206a will compress the return spring 206b, so that when the flange assembly 500 is disconnected from the support plate 201, the return spring 206b will push the piston block 206a to return, and push the support plate 201 to return, and the pressure block 204c slides downward, so that the arc pressure strip 204 rotates outward to return to its original position. Since the convex ring 201c-2 is in the ring mouth 204b-1, the convex ring 201c-2 limits the sleeve 204b to ensure that the sleeve 204b will not deviate arbitrarily on the positioning rod 201c, and ensure the stable rotation of the sleeve 204b. When the flange assembly 500 is driven to rotate, the flange assembly 500 will drive the friction tooth block 204a to rotate at the port position of the arc pressure strip 204;

[0054] It should be noted that the weight of the pressure block 204 c is greater than the weight of the arc-shaped pressure strip 204 , so when the pressure block 204 c is not pushed by an external force, it will directly drive the arc-shaped pressure strip 204 to return to its original position and rotate.

[0055] Example 4

[0056] See also Figure 3 , Figure 5 , Figure 6 , Fig.11 and 12 On the basis of Example 1, this embodiment uses the travel port 305a in conjunction with the travel block 303a-1 to facilitate the movement of the shaft rod 304. At the same time, the use of the compression spring 304c can facilitate the resetting of the suction ball 304b and the control of the detachment of the suction cup 301a.

[0057] Specifically, the end surface of the air cylinder 303 away from the air disk 301 is provided with a blocking hole 303b with a smaller aperture than the inner diameter of the air cylinder 303, the surface wall of the suction ball 304b is fixed with a compression spring 304c sleeved on the shaft 304, the upper end surface of the movable bar 202 is fixed with a circular plate 203, the air cylinder 303 is rotatably connected with the circular plate 203 through a bearing, a pushing spring 302 is provided between the air disk 301 and the circular plate 203, a U-shaped plate 303a is fixed to the end of the air cylinder 303, a linkage bar 305 is slidably provided at the inner side position of the U-shaped plate 303a, and both side walls of the linkage bar 305 are provided with travel openings 305a, and the inner side wall of the U-shaped plate 303a is fixed with two travel blocks 303a-1 which slide respectively at the inner positions of the travel openings 305a;

[0058] Through the arrangement and use of the above-mentioned structure, when the linkage bar 305 is controlled to rotate, the linkage bar 305 will drive the rotating cylinder 304a to move through the rotating rod 305c inside the rotating mouth 305b. At the same time, in order to avoid the limitation of the shaft rod 304, the linkage bar 305 is controlled to move along the inside of the U-shaped plate 303a, so that the travel mouth 305a on the linkage bar 305 will slide along the travel block 303a-1, ensuring that the linkage bar 305 will not cause uneven force on the shaft rod 304 when driving the shaft rod 304 to move. At the same time, when the shaft rod 304 moves outward inside the blocking hole 303b, the shaft rod 304 will drive the suction ball 304b to slide in the direction of the blocking hole 303b, thereby compressing the The spring 304c is compressed, so after the user releases the linkage bar 305, the compression spring 304c is no longer pulled by the external force, so the compression spring 304c will push the suction ball 304b to reset, and at the same time, the flange assembly 500 is set at the upper end position of the support plate 201, firstly, the air cylinder 303 is pulled to make the air disk 301 away from the support plate 201, and then the air disk 301 compresses the pushing spring 302. Therefore, when the flange assembly 500 is at the upper end position of the support plate 201, the air cylinder 303 is released, and then the pushing spring 302 will directly push the air cylinder 303 to move in the direction of the flange assembly 500, so that the suction cup 301a is in contact with the end face of the pipe on the flange assembly 500.
