Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to a transformer installation device for electric power engineering. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. During the power transmission process, the electric energy generated by the power plant needs to be transmitted over long distances to various power consumption areas. In order to reduce the power loss on the transmission line, high-voltage transmission is used. The power plant first uses a step-up transformer to increase the low voltage output by the generator to several hundred kilovolts. When it reaches the power consumption end, a step-down transformer is used to gradually reduce the high voltage to different levels of voltage such as 220V and 380V suitable for users, which is suitable for various electrical equipment: During the installation of the transformer, it is usually necessary to first connect the two poles through a support plate, and then use a crane to place the transformer on the support plate for position adjustment and fixation. Since this installation method is mainly through the bottom of the transformer contacting the support plate and fixing it through bolts, when the bottom of the transformer is in contact with the support plate, the contact area between the support plate and the transformer is small, the transformer may become unstable when the position is adjusted through the support plate, thereby affecting the installation of the transformer. Summary of the invention

[0006] Furthermore, a fixing mechanism is provided inside the groove one, and the fixing mechanism includes a hollow block fixedly connected to the side of the push rod away from the telescopic rod, two sliding rods are slidably connected inside the hollow block, a connecting plate is rotatably connected to the side of the sliding rod away from the hollow block, and an arc plate is rotatably connected between the two connecting plates.

[0007] Furthermore, the side wall of the arc-shaped plate is provided with two sliding grooves, and the two connecting plates are rotatably connected to a right-angle plate at one side away from the arc-shaped plate, and the side wall of the right-angle plate is provided with two rectangular grooves.

[0008] Furthermore, a rotating mechanism is arranged on the inner wall of the sliding groove, and the rotating mechanism comprises a connecting rod slidably connected inside the sliding groove, a side of the connecting rod away from the sliding groove is fixedly connected to the right angle plate, and a side of the connecting rod close to the connecting plate is fixedly connected to a telescopic rod 2.

[0009] Furthermore, a rack three is fixedly connected to one side of the telescopic rod two close to the right-angle plate, the top and bottom of the rack three are both slidably connected to the inside of the rectangular groove, a gear two is meshed with one side of the rack three close to the rectangular groove, the side wall of the gear two is rotatably connected to the inside of the rectangular groove, and a cam is fixedly connected to the outer surface of the gear two.

[0010] Furthermore, a stabilizing mechanism is provided on the outer surface of the right-angle plate, and the stabilizing mechanism includes four fixed blocks 2 fixedly connected to the side wall of the right-angle plate. The four fixed blocks 2 are symmetrically arranged in groups of two, and the two groups of fixed blocks 2 are distributed at right angles. A clamping plate is rotatably connected between the two fixed blocks 2.

[0011] Furthermore, an air pipe is fixedly connected to one side of the clamping plate close to the right-angle plate, and a side of the air pipe away from the clamping plate penetrates through the outer wall of the right-angle plate and extends to the outside, and an extended end of the air pipe is fixedly connected to an air cylinder, and a side of the air cylinder close to the connecting plate is fixedly connected to the side wall of the connecting plate, and a piston rod is slidably connected to the inside of the air cylinder, and an arc block is rotatably connected to one end of the piston rod close to the connecting rod, and the arc block is fixedly connected to the connecting rod on the side away from the air cylinder.

[0012] The present invention has the following beneficial effects: (1) In the present invention, when installing a mobile transformer, the transformer is first placed on the top of the groove 1 provided on the support frame, and then the transformer is slowly placed on the top of the sliding plate. When the transformer is placed downward, the sliding plate located at the bottom of the transformer is pushed downward by the transformer, and at the same time, the telescopic table located at the bottom of the sliding plate begins to shrink due to the downward pressure of the sliding plate, and one end of the rotating rod located in the side strip groove thereof slides downward and begins to swing around the support rod to drive the other end to swing upward. When the end of the rotating rod away from the telescopic table swings upward, the moving block slides toward the inner side of the rack 1 and applies an upward thrust to the rack 1 located in the groove 2. When the rack 1 receives the thrust and moves upward, it drives the rack 1 to move upward. The meshed gear 1 rotates clockwise to drive the rack 2 on the other side to move downward. When the rack 2 moves downward, the two telescopic rods 1 located on the top of the rack 2 will swing toward the groove 1 to drive the push bar to pull the spring 2 to extend in the direction of the transformer. When the push bar moves, it will push the hollow block on its top to move synchronously toward the transformer, thereby exerting pressure on the transformer. The transformer is squeezed by the hollow blocks in four different directions so that the transformer can remain stable during the descent process, avoiding the transformer from tilting when the transformer is placed in the groove 1 in the first step. At the same time, the four hollow blocks will also play a fixing role when squeezing the transformer, thereby facilitating secondary fixation of the transformer during subsequent installation.

[0013] (2) According to the present invention, when the hollow block moves, the two slide bars inside the hollow block are caused to slide relatively inside the hollow block because the distance between the connecting plate connected to the two slide bars and the hollow block is shortened. At the same time, the connecting plate located on one side of the slide bar is pulled outward by the pulling force brought by the movement of the slide bar toward the hollow block, while driving the arc plate to contract. At this time, the right-angle plate is pushed forward by the connecting plate, thereby applying pressure to the right angle of the transformer for clamping. When the clamp clamps the transformer in a right-angle shape, it can apply pressure to the transformer from multiple directions. Compared with single-point or simple linear clamping, the support of the right-angle clamping is more stable, which effectively alleviates the shaking of the transformer during installation and ensures the stability of the transformer during installation.

[0014] (3) In the present invention, when the arc plate contracts, the connecting rod located inside the sliding groove will slide outward. Since the connecting rod is an obtuse angle as a whole, when the connecting rod moves, it will push the telescopic rod 2 inside it to slide in the same direction, thereby driving the rack 3 to slide in the rectangular groove toward the connecting plate and driving the gear 2 and the cam at its bottom to rotate clockwise. When the cam rotates, it will push the clamping plate to rotate between the two fixed blocks toward the transformer, thereby squeezing the transformer. At the same time, when the connecting rod slides, the arc block will push the piston rod to move into the gas cylinder. When the piston rod moves, it will push the gas to move into the clamping plate through the gas pipe, thereby expanding the rubber pad on the surface of the clamping plate. The transformer is squeezed by the expansion of the rubber pad, which can further enhance the stability of the transformer during installation and reduce the damage caused by collision during installation, thereby ensuring that the transformer can be installed smoothly.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the mobile transformer is installed, the transformer is first placed on the top of the groove 101 opened on the support frame 1, and then the transformer is slowly placed on the top of the sliding plate 103, and then the transformer is placed downward. When the sliding plate 103 at the bottom of the transformer is moved downward by the thrust of the transformer, and the telescopic platform 201 at the bottom of the sliding plate 103 begins to shrink due to the downward pressure of the sliding plate 103, and one end of the rotating rod 202 located in the side strip groove slides downward and begins to swing around the support rod 203 to drive the other end to swing upward. When the end of the rotating rod 202 away from the telescopic platform 201 swings upward, the moving block 204 slides toward the inner side of the rack 1 301 and applies an upward thrust to the rack 1 301 located in the groove 2 103. When the rack 1 301 receives the thrust and moves upward, it drives the gear 1 302 meshing with the rack 1 301 to rotate clockwise, thereby driving the rack 2 303 on the other side to move downward.

[0028] The outer surface of the push rod 305 is slidably connected to the inside of the auxiliary groove, and a spring 306 is fixedly connected to the top of the push rod 305. The side of the spring 306 away from the rack 1 301 is fixedly connected to the side wall of the auxiliary groove. When the rack 2 303 moves downward, the two telescopic rods 1 304 located on the top of the rack 2 303 will swing toward the groove 1 101, thereby driving the push bar 305 to pull the spring 2 306 to extend toward the direction of the transformer.

[0029] A fixing mechanism 4 is provided inside the groove 101, and the fixing mechanism 4 includes a hollow block 401 fixedly connected to the side of the push rod 305 away from the telescopic rod 304, and two sliding rods 402 are slidably connected inside the hollow block 401, and a connecting plate 403 is rotatably connected to the side of the sliding rod 402 away from the hollow block 401, and an arc plate 404 is rotatably connected between the two connecting plates 403. When the push bar 305 moves, it will push the hollow block 401 on its top to move synchronously toward the transformer, thereby applying pressure to the transformer.

[0030] Two sliding grooves 405 are provided on the side wall of the arc plate 404, and the two connecting plates 403 are rotatably connected to a right-angle plate 406 on one side away from the arc plate 404. The side wall of the right-angle plate 406 has two rectangular grooves 407. When the hollow block 401 moves, the two sliding rods 402 inside it shorten the distance between the connecting plates 403 connected to them and the hollow block 402, so that the sliding rods 402 slide relatively inside the hollow block 401. At the same time, the connecting plate 403 located on one side of the sliding rod 402 is pulled outward by the pulling force brought by the sliding rod 402 moving toward the direction of the hollow block 401, while driving the arc plate 404 to contract. At this time, the right-angle plate 406 will be pushed forward by the connecting plate 403, thereby applying pressure on the right angle of the transformer to clamp it.

[0031] A rotating mechanism 5 is arranged on the inner wall of the sliding groove 405, and the rotating mechanism 5 includes a connecting rod 501 which is slidably connected to the inside of the sliding groove 405, and the side of the connecting rod 501 away from the sliding groove 405 is fixedly connected to the right-angle plate 406, and the side of the connecting rod 501 close to the connecting plate 403 is fixedly connected to the second telescopic rod 502. When the arc plate 404 contracts, the connecting rod 501 located inside the sliding groove 405 will slide outward. Because the connecting rod 501 is at an obtuse angle as a whole, when the connecting rod 501 moves, it will push the second telescopic rod 502 inside it to slide in the same direction.

[0032] A rack three 503 is fixedly connected to one side of the telescopic rod 2 502 close to the right-angle plate 406, and the top and bottom of the rack three 503 are both slidably connected to the inside of the rectangular groove 407. A gear two 504 is meshed with one side of the rack three 503 close to the rectangular groove 407, and the side wall of the gear two 504 is rotatably connected to the inside of the rectangular groove 407. A cam 505 is fixedly connected to the outer surface of the gear two 504. When the connecting rod 501 moves, the telescopic rod 2 502 on its inner side will be pushed to slide in the same direction, thereby driving the rack three 503 to slide in the direction of the connecting plate 403 in the rectangular groove, and driving the gear two 504 and the cam 505 at its bottom to rotate clockwise.

[0033] A stabilizing mechanism 6 is provided on the outer surface of the right-angle plate 406, and the stabilizing mechanism 6 includes four fixed blocks 601 fixedly connected to the side wall of the right-angle plate 406. The four fixed blocks 601 are symmetrically arranged in groups of two, and the two groups of fixed blocks 601 are distributed at right angles. A clamping plate 602 is rotatably connected between the two fixed blocks 601. When the cam 505 rotates, the clamping plate 602 is pushed to rotate between the two fixed blocks 601 toward the transformer, thereby squeezing the transformer.

[0034] The side of the clamping plate 602 close to the right-angle plate 406 is fixedly connected to an air pipe 603, and the side of the air pipe 603 away from the clamping plate penetrates through the outer wall of the right-angle plate 406 and extends to the outside, and the extended end of the air pipe 603 is fixedly connected to a gas cylinder 604. The side of the gas cylinder 604 close to the connecting plate 403 is fixedly connected to the side wall of the connecting plate 403, and the inside of the gas cylinder 604 is slidably connected to a piston rod 605, and the end of the piston rod 605 close to the connecting rod 501 is rotatably connected to an arc block 606, and the side of the arc block 606 away from the gas cylinder 604 is fixedly connected to the connecting rod 501. At the same time, when the connecting rod 501 slides, the arc block 606 will push the piston rod 605 to move into the gas cylinder, and when the piston rod 605 moves, it will push the gas to move into the clamping plate 602 through the gas pipe 604, thereby expanding the rubber pad on the surface of the clamping plate 602.

[0035] When in use, first move the transformer so that the transformer is located at the top of the groove 101 opened in the support frame 1, and then slowly place the transformer on the top of the sliding plate 103. When placing the transformer downward, the sliding plate 103 located at the bottom of the transformer moves downward by the thrust of the transformer. At the same time, the telescopic table 201 located at the bottom of the sliding plate 103 will begin to shrink due to the downward pressure of the sliding plate 103, and one end of the rotating rod 202 located in the side strip groove thereof will slide downward and begin to swing around the support rod 203 to drive the other end to swing upward. When the end of the rotating rod 202 away from the telescopic table 201 swings upward, the moving block 204 will slide toward the inner side of the rack 1 301 and apply an upward thrust to the rack 1 301 located in the groove 2 103. When the rack 1 301 receives the thrust and moves upward, it will drive the rack 1 301 The meshed gear 1 302 rotates clockwise to drive the rack 2 303 on the other side to move downward. When the rack 2 303 moves downward, the two telescopic rods 1 304 located on the top of the rack 2 303 will swing toward the groove 101 to drive the push bar 305 to pull the spring 2 306 to extend in the direction of the transformer. When the push bar 305 moves, it will push the hollow block 401 on its top to move synchronously toward the transformer, thereby applying pressure to the transformer. The transformer is squeezed by the four hollow blocks 401 in different directions so that the transformer can remain stable during the descent process, thereby avoiding the transformer from tilting when the transformer is placed in the groove 101 in the first step. At the same time, the four hollow blocks 401 will also play a fixing role when squeezing the transformer, thereby facilitating secondary fixing of the transformer during subsequent installation.

[0036] When the hollow block 401 moves, the two sliding rods 402 inside it shorten the distance between the connecting plate 403 connected to it and the hollow block 402, so that the sliding rod 402 slides relatively inside the hollow block 401. At the same time, the connecting plate 403 located on one side of the sliding rod 402 opens outward due to the pulling force brought by the sliding rod 402 moving toward the hollow block 401, while driving the arc plate 404 to contract. At this time, the right-angle plate 406 will be pushed forward by the connecting plate 403 to apply pressure to the right angle of the transformer for clamping. When the clamp clamps the transformer in a right-angle shape, it can apply pressure to the transformer from multiple directions. Compared with single-point or simple linear clamping, the support of the right-angle clamping is more stable, which effectively alleviates the shaking of the transformer during installation and ensures the stability of the transformer during installation.

[0037] When the arc plate 404 contracts, the connecting rod 501 located inside the sliding groove 405 will slide outward. Since the connecting rod 501 is at an obtuse angle as a whole, when the connecting rod 501 moves, it will push the telescopic rod 2 502 inside it to slide in the same direction, thereby driving the rack 3 503 to slide in the rectangular groove toward the connecting plate 403 and driving the gear 2 504 and the cam 505 at the bottom thereof to rotate clockwise. When the cam 505 rotates, it will push the clamping plate 602 to rotate between the two fixed blocks 601 toward the transformer direction. Thereby, the transformer is squeezed. At the same time, when the connecting rod 501 slides, the arc block 606 pushes the piston rod 605 to move into the gas cylinder. When the piston rod 605 moves, the gas is pushed through the gas pipe 604 to move into the clamping plate 602, thereby expanding the rubber pad on the surface of the clamping plate 602. The expansion of the rubber pad squeezes the transformer, which can further enhance the stability of the transformer during installation and reduce the damage caused by collision during the installation of the transformer, ensuring that the transformer can be installed smoothly.
