Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a body pressing device for a power transformer and a use method thereof. Background Art

[0002] A transformer is an electrical device used in power systems, mainly used to increase and decrease voltage to meet different transmission and usage requirements;

[0003] During the production and assembly process of transformers, it is necessary to perform a compacting operation on the transformer body. Compacting the transformer body is a necessary measure to ensure its safe, stable and efficient operation. The compacting measure significantly improves the overall performance and reliability of the transformer by reducing vibration, improving mechanical strength, optimizing magnetic properties and enhancing insulation properties. In the prior art, the compacting of the transformer is completed by aligning the holes in the body with the rods in the oil tank and tightening them. However, in actual operation, since the volume of the body is adapted to the internal volume of the oil tank and the space is small, it is not convenient to observe the relative position of the rods in the oil tank and the holes in the body during the compacting operation, resulting in the need to frequently observe and adjust the position to complete the docking, which is not convenient for improving operational efficiency and is prone to deviations. Therefore, it needs to be improved. Summary of the Invention

Notches are symmetrically provided at both ends of the base, and contacts are fixedly installed in the notches. The bottom of the contact is slidably connected to a release member, and a pry bar is provided at the bottom of the release member, which is rotatably connected to the base. The pry bar is used to push the release member upward so that the two inclined rods are relatively far apart.

[0015] Preferably, it also includes a baffle, which is fixedly mounted on one end of the conveying frame and functions to facilitate the control of the lifting arm and the clamping member to lift the device body.

[0016] Preferably, a method for using a body pressing device for a power transformer comprises the following steps:

[0017] S1: Before the compaction operation begins, the operator places the oil tank body horizontally on the workbench, with the bottom of the oil tank body within the space formed by the I-shaped rod and the side rod. The device body is then placed on the conveyor frame. The rollers on the conveyor frame convey the device body until it contacts the baffle, and the device body stops moving. The turntable is then started to drive the boom to rotate toward the device body. After the boom is in place, the upper arm moves downward. During this process, the clamp opens outward and tightens inward when it contacts the top of the device body, clamping the top of the device body. The boom then rises and rotates 90 degrees to the top of the workbench and is lowered.

[0018] S2: During the lowering of the boom, the pressure rod presses the guide plate 1 downward to rotate the roller shaft, which drives the guide plate 2 to rotate with the center point of the roller shaft as the axis to swing downward. The guide plate 2 pushes the cross bar to slide in the direction of the workbench. During the process, the spring 1 is gradually compressed and drives the connecting rod forward, so that the cam drives the tensioning strip to rotate at the bottom of the workbench. The two ends of the tensioning strip pull the connecting rod, and the connecting rod drives the two symmetrically arranged I-shaped rods to move toward the center of the workbench at the same time. The pull rod follows the movement of the I-shaped rod and is guided by the inclined slot. The pull rod slides, and during the process, the side rod is gradually pulled by the connector and the side wheel, so that the two inclined side rods gradually tend to be straightened, and the two I-shaped rods approach each other, and the inner edges of the two I-shaped rods and the two side rods form a space of the same size as the bottom of the fuel tank body. During the process, the inner edges of the side rods and the I-shaped rods touch the bottom of the fuel tank body, and the fuel tank body is corrected and aligned to keep it in a centrally symmetrical state with the main body above. Before the bottom of the main body enters the fuel tank body, the correction and alignment of the fuel tank body is completed;

[0019] S3: After the boom continues to lower so that the bottom of the device body contacts the threaded rod, when one end of the side push rod contacts the surface of the vertical plate, the toothed plate and the toothed rod are synchronously meshed, and the toothed rod drives the toothed belt to rotate, and drives the triangular roller to rotate through bevel gear 1 and bevel gear 2. When the triangular roller rotates, it pushes the vertical plate forward, and the vertical plate pushes the side push rod to move toward the end close to the sleeve box, compressing spring 2, so that the sleeve box drives the device body to move through the clamping part, and then the edge of the triangular roller disengages from the vertical plate after rotation, so that spring 2 returns to its position, and the device body moves back. The triangular roller is driven to rotate continuously during the downward movement of the toothed plate, and the triangular roller intermittently pushes the vertical plate to move during the rotation, so that the device body vibrates. , so that the top of the threaded rod passes smoothly through the docking hole opened at the bottom of the device body. After the threaded rod and the docking hole are docked, the boom continues to lower, and the two inclined rods contact the surface of the contact, so that the distance between the inclined rods is widened. When it moves to the bottom of the contact, the two inclined rods automatically return to their original positions under the action of spring three and press and clamp the bottom of the contact. After clamping, the clamping part automatically releases and the boom rises. The operator then installs the bolt on the threaded rod through the nut to fix the device body and the oil tank body relatively, thus completing the clamping operation on the device body. When it is necessary to remove the device body from the oil tank body, press the pry bar to slide the release part upward to push the two inclined rods outward.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, by providing an auxiliary alignment mechanism, when the top of the threaded rod touches the bottom of the device body, the tooth plate engages with the toothed rod and drives the toothed rod to rotate, driving the triangular roller to continuously rotate and push the vertical plate. The vertical plate pushes the side push rod to transmit the vibration to the sleeve, so that the sleeve is driven by the clamping member to continuously vibrate the device body. By outputting a short distance of vibration during the lowering of the boom, the threaded rod is docked with the docking hole. During the pressing operation, the docking can be quickly achieved and the docking accuracy is improved.

[0022] 2. In the present invention, the contact and inclined rod are provided. After the docking hole at the bottom of the device body is docked with the threaded rod, the inclined rod is opened during its downward movement and clamps below the contact, causing the docking mechanism to clamp and limit the bottom sides of the device body. If the inner diameter of the docking hole is slightly larger than the outer diameter of the threaded rod, the position of the device body can be restricted before the bolt is installed to prevent the device body from shifting.

[0023] 3. In the present invention, by providing a positioning mechanism, when the boom lowers the device body, the two I-shaped rods are driven to be relatively close, and the two side rods are gradually straightened from being tilted. During the process, the position of the oil tank is straightened, so that the oil tank and the device body maintain central symmetry. This not only improves the accuracy when the device body and the oil tank are pressed tightly, but also greatly reduces the time required for the operator to adjust the position of the oil tank. In addition, when the device body is vibrated and aligned, the oil tank can be limited to prevent the oil tank from shifting due to vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] S1: Before the compacting operation begins, the operator places the oil tank body 3 horizontally on the workbench 1, with the bottom of the oil tank body 3 located within the space formed by the I-shaped rod 511 and the side rod 512. The device body 4 is then placed on the conveyor frame 2. The roller 502 on the conveyor frame 2 conveys the device body 4 until it contacts the baffle 8, and the device body 4 stops moving. The turntable 601 is then started to drive the boom 602 to rotate toward the device body 4. After the boom 602 is in place, the upper arm moves downward.

10. The method for using the body pressing device for a power transformer according to claim 1, characterized in that: The steps include: S1: Before the compacting operation begins, the operator places the oil tank body (3) horizontally on the workbench (1), and the bottom of the oil tank body (3) is located within the space formed by the I-shaped rod (511) and the side rod (512). Then, the device body (4) is placed on the conveying frame (2). The roller (502) on the conveying frame (2) conveys the device body (4) until it contacts the baffle (8). Then, the device body (4) stops moving. Then, the turntable (601) is started to drive the boom (602) to rotate toward the device body (4). After the boom (602) is in place, the upper arm moves downward. During the process, the clamping member (603) opens outward. When the clamping member (603) contacts the top of the device body (4), the clamping member (603) tightens inward to clamp the top of the device body (4). Then, the boom (602) rises and rotates ninety degrees to the top of the workbench (1) and is lowered. S2: During the lowering of the boom (602), the pressure rod (604) presses the guide plate 1 (503) downward, causing the roller (502) to rotate. During the process, the guide plate 2 (504) is driven to rotate with the center point of the roller (502) as the axis to swing downward. The guide plate 2 (504) pushes the cross bar (505) to slide in the direction of the workbench (1). During the process, the spring 1 (519) is gradually compressed and drives the connecting rod (506) to push forward, causing the cam (510) to drive the tensioning strip (508) to rotate at the bottom of the workbench (1). The two ends of the tensioning strip (508) pull the connecting rod (509), and the connecting rod (509) drives the two symmetrically arranged I-shaped rods (511) to move toward the center of the workbench (1) at the same time. The pull rod (514) moves along with the I-shaped rod (511). During the movement, the inclined groove (102) guides the pull rod (514) to slide. During the movement, the side rod (512) is gradually pulled by the connector (515) and the side wheel (516), so that the two inclined side rods (512) gradually tend to be aligned, and the two I-shaped rods (511) approach each other. The inner edges of the two I-shaped rods (511) and the two side rods (512) form a space of the same size as the bottom of the fuel tank body (3). During the movement, the inner edges of the side rods (512) and the I-shaped rods (511) touch the bottom of the fuel tank body (3), and the fuel tank body (3) is corrected and aligned to keep it in a centrally symmetrical state with the upper body (4). Before the bottom of the body (4) enters the fuel tank body (3), the correction and alignment of the fuel tank body (3) is completed; S3: After the boom (602) is lowered further so that the bottom of the body (4) contacts the threaded rod (902), one end of the side push rod (704) contacts the surface of the vertical plate (712), the toothed plate (705) and the toothed rod (707) are synchronously meshed, the toothed rod (707) drives the toothed belt (708) to rotate, and drives the triangular roller (711) to rotate through the bevel gear 1 (709) and the bevel gear 2 (710), and the triangular roller (711) rotates, pushing the vertical plate (712) forward, and the vertical plate (712) The side push rod (704) is pushed to move toward one end of the sleeve box (701), compressing the second spring (703), so that the sleeve box (701) drives the body (4) to move through the clamping member (603), and then the triangular roller (711) rotates and its edge is disengaged from the vertical plate (712), so that the second spring (703) returns to its position, and the body (4) moves back. The triangular roller (711) is driven to rotate continuously during the downward movement of the tooth plate (705), and the triangular roller (711) is intermittently pushed during the rotation of the vertical plate (712). 2) The moving method causes the device body (4) to vibrate, so that the top of the threaded rod (902) smoothly passes through the docking hole (903) opened at the bottom of the device body (4). After the threaded rod (902) and the docking hole (903) are docked, the two inclined rods (904) contact the surface of the contact (907) during the process of the hanging arm (602) continuing to be lowered, so that the distance between the inclined rods (904) is expanded. When moving to the bottom of the contact (907), the two inclined rods (904) are acted upon by the spring (905). The force automatically returns to its original position and presses against and clamps the bottom of the contact (907). After clamping, the clamping member (603) automatically loosens and the boom (602) rises. The operator then installs the bolt on the threaded rod (902) through the nut to relatively fix the device body (4) and the oil tank body (3). The pressing operation of the device body is completed. When it is necessary to remove the device body (4) from the oil tank body (3), the pry bar (909) is pressed to slide the release member (908) upward to push the two inclined rods (904) outward.
