Description

Technical Field

[0001] The invention relates to the technical field of transformer installation, and in particular to an installation device for a transformer telescopic shell. Background Art

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to convert AC power of one voltage level into AC power of another voltage level. It is mainly composed of an internal iron core, coil windings, insulating materials and an external protective casing. The transformer casing is a protective shell that can adaptively expand and contract according to the thermal expansion and contraction of internal components of the transformer such as coils and iron cores. This casing design aims to solve the stress problem that may be caused by changes in the size of internal components due to temperature changes during the operation of the transformer.

[0003] When producing a transformer, the internal components need to be installed into the protective shell by hoisting. When the transformer is hoisted using existing transformer installation equipment, the hoisting points are located at the four corners of the transformer cover. Due to the large mass of the transformer, the pulling force of the hoisting rope on the transformer during the hoisting process is located at the four corners of the transformer cover. The outer side of the transformer cover is prone to warping and deformation upwards, resulting in the inability to cover the protective shell after the transformer is placed in the protective shell.

[0004] Furthermore, in the process of placing the transformer into the protective shell, the existing transformer installation equipment has the load-bearing ropes on the upper side of the transformer converge into a main lifting rope, which makes the transformer prone to rotational offset. When aligning and calibrating the transformer and the protective shell, the load-bearing ropes may cause the transformer to rotate and offset, requiring staff to perform preliminary alignment and calibration of the transformer. However, there is a certain deviation in the manual alignment of the transformer, and it is impossible to ensure that the transformer and the oil tank are aligned. As a result, the transformer is rotated and offset when placed in the oil tank, causing collision with the shell, resulting in damage to the transformer. Summary of the invention

[0005] In order to overcome the shortcomings of existing transformer installation equipment that the outer side of the transformer cover is easily warped and deformed upwards during the process of lifting the transformer, resulting in the transformer being unable to cover the protective shell, the transformer causing rotational deviation and collision with the shell, resulting in damage to the transformer, the present invention provides an installation device for a transformer telescopic shell.

DETAILED DESCRIPTION

[0029] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0030] Example 1

[0031] like Figure 3-Figure 4 As shown, a device for installing a telescopic housing of a transformer 5 includes a hanging frame 1 and a hanging ring 2; the hanging frame 1 is provided with four hanging rings 2 distributed in a rectangular shape; the hanging frame 1 is connected to an external hanging device through the hanging ring 2; a transformer 5 is hung below the hanging frame 1; a cover plate is installed on the transformer 5; a plurality of hooks 5001 distributed in a rectangular shape are provided on the cover plate; an oil tank 6 is placed below the transformer 5;

[0032] It also includes a hanging assembly, a pressing plate 3 and a calibration system; the hanging frame 1 is connected to the hanging assembly; the hanging assembly is connected to two left-right symmetrical pressing plates 3; the hanging frame 1 is connected to the calibration system.

[0033] The hoisting assembly includes a roller 101, a rotating plate 102 and a hanging rope 103; four rollers 101 distributed in a rectangular shape are rotatably connected to the hoisting frame 1; four rotating plates 102 distributed in a rectangular shape are rotatably connected to the lower side of the hoisting frame 1; each two rotating plates 102 adjacent to each other are rotatably connected to the upper side of a pressing plate 3; each rotating plate 102 is located below the adjacent rollers 101; each rotating plate 102 is fixedly connected to a hanging rope 103; each hanging rope 103 is fixedly connected to a hook; Figure 4 As shown, the hook on each lifting rope 103 passes around the upper side of the adjacent roller 101 and hooks the corresponding hook ring 5001.

[0034] Also includes a guide plate 4; each pressing plate 3 is fixed to a guide plate 4 on the lower side; Figure 4 As shown, the lower side of each guide plate 4 is arranged in an inclined state; the distance between the upper parts of the two guide plates 4 facing each other is equal to the length of the cover plate of the transformer 5.

[0035] The present invention uses the pressing plate 3 to press the cover plate around the hook ring 5001 when hoisting the transformer 5, thereby solving the problem that the outer side of the cover plate is easily warped upwards due to the force point being located at the edge of the cover plate when the transformer 5 is hoisted. The specific process is as follows:

[0036] When installing the transformer 5 into the oil tank 6, the external lifting equipment is controlled to hook the lifting ring 2 so that the lifting frame 1 drives the pressing plate 3 to move onto the transformer 5. Figure 3As shown, the pressing plate 3 is placed on the transformer 5, and then the hook on each lifting rope 103 is hooked on the corresponding hook ring 5001 to fix the transformer 5, and then the external lifting equipment is controlled to make the lifting frame 1 drive the transformer 5 to rise. During the rising process of the lifting frame 1, the lifting rope 103 moves on the roller 101 after receiving the pulling force of the lifting frame 1, and gradually straightens, and the connection between the rotating plate 102 and the lifting rope 103 is pulled upward, so that the rotating plate 102 rotates on the lifting frame 1, and the connection between the rotating plate 102 and the pressing plate 3 is moved downward, driving the pressing plate 3 to press down on the transformer 5, and when the pressing plate 3 is used to lift the transformer 5, the cover plate around the hook ring 5001 is pressed, so that , so that the pulling force applied by the lifting rope 103 to the transformer 5 is converted into a downward pressure on the transformer 5, preventing the cover of the transformer 5 from being easily warped upward due to the lifting, and preventing the cover of the transformer 5 from being unable to fit with the upper side of the oil tank 6 after being placed in the oil tank 6, thereby enhancing the protection effect of the cover of the transformer 5 when installing the transformer 5, and the structure is ingenious, without the need for an additional power structure. At the same time, when the transformer 5 is lifted, the cover around the hook ring 5001 is pressed by the pressing plate 3, so that the transformer 5 and the lifting frame 1 are in close contact, preventing the transformer 5 from shaking on the lifting frame 1 due to the movement of the lifting equipment, avoiding the transformer 5 and the inner wall of the oil tank 6 from wearing and bumping against each other, and enhancing the protection effect of the transformer 5 and the oil tank 6.

[0037] When the transformer 5 is about to be completely placed in the oil tank 6, the pressing plate 3 descends together with the transformer 5, so that the guide plate 4 first contacts the upper edge of the oil tank 6. As the hanging frame 1 continues to move downward, the guide plate 4 will be squeezed against the edge of the oil tank 6. At this time, the guide plate 4 moves horizontally compared to the oil tank 6, and drives the transformer 5 to move together. Since the spacing between the upper parts of the two guide plates 4 facing each other is equal to the length of the transformer 5 cover plate, the guide plate 4 guides the deviated transformer 5 toward the middle of the oil tank 6 to prevent the transformer 5 from deviating when entering the oil tank 6, and to avoid the inability to overlap the bolt holes between the transformer 5 and the oil tank 6, thereby improving the accuracy of the installation of the transformer 5 and the oil tank 6.

[0038] Example 2

[0039] On the basis of Example 1, Figure 5-Figure 7 As shown, the calibration system includes a movable plate 201, a driving assembly, a moving block 202 and a guide block 203; four rectangularly distributed movable plates 201 are movably arranged on the hanging frame 1; each movable plate 201 is provided with a sliding groove; all movable plates 201 are connected with a driving assembly; a moving block 202 is slidably connected to the lower side of each movable plate 201; all moving blocks 202 are connected to the driving assembly; the moving block 202 is driven to move by the driving assembly; a guide block 203 is rotatably connected to the lower side of each moving block 202 through a torsion spring; all guide blocks 203 are initially arranged as shown in the figure. Figure 6 The tilted state shown.

[0040] The driving assembly includes a first driving member 204 ; each movable plate 201 is fixedly connected with a first driving member 204 , and the first driving member 204 is an electric push rod; the telescopic end of each first driving member 204 is fixedly connected to the adjacent moving block 202 .

[0041] The calibration system further includes a rubber block 205 ; each moving block 202 is fixedly connected with a rubber block 205 .

[0042] The calibration system also includes a power component, an insertion rod 206 and an elastic member 207; the lifting frame 1 is connected to a power component; four insertion rods 206 distributed in a rectangular shape are connected to the power component; the insertion rods 206 are driven to move by the power component; each insertion rod 206 is provided with a sensor; each movable plate 201 is provided with two sockets 20101; each movable plate 201 is fixedly connected to an elastic member 207, and the elastic member 207 is a spring; all elastic members 207 are fixedly connected to the lifting frame 1; the elastic force of all elastic members 207 is greater than the torsion of the torsion spring between the moving block 202 and the guide block 203.

[0043] The power assembly includes a second driving member 208 ; two front-to-back symmetrical second driving members 208 are connected to the hanging frame 1 , and the second driving member 208 is a bidirectional cylinder; the two telescopic ends of each second driving member 208 are respectively fixedly connected to the corresponding insertion rod 206 .

[0044] Each rubber block 205 is provided with a notch 20501 ; the transformer 5 is provided with a plurality of support rods 5002 distributed in a rectangular shape; each notch 20501 is directly opposite to an adjacent support rod 5002 .

[0045] The present invention guides and calibrates the transformer 5 by means of the guide block 203, thereby solving the problem that the transformer 5 and the inner wall of the oil tank 6 wear and collide with each other due to rotational deviation when the transformer 5 is placed in the oil tank 6. The specific working process is as follows:

[0046] After the lifting frame 1 is controlled to drive the transformer 5 to move above the oil tank 6, the external lifting equipment is controlled to make the lifting frame 1 drive the transformer 5 to descend. Before the transformer 5 enters the oil tank 6, the lifting frame 1 drives the movable plate 201 and the guide block 203 to descend. Figure 6As shown, the transformer 5 is manually oriented to make it preliminarily aligned with the oil tank 6. However, it is impossible to ensure that the transformer 5 and the oil tank 6 are aligned by manual orientation. There is a certain deviation in manual operation, which causes the transformer 5 to collide with the oil tank 6 when the transformer 5 is placed in the oil tank 6. Therefore, after the transformer 5 is manually oriented to make it preliminarily aligned with the oil tank 6, the lifting frame 1 is controlled to drive the movable plate 201 and the guide block 203 to continue to descend. At this time, the two diagonally opposite rubber blocks 205 first contact the inner edge of the upper side of the oil tank 6. As the lifting frame 1 continues to drive the movable plate 201 and the guide block 203 to continue to descend, The plate 201 and the guide block 203 descend, and the guide block 203 and the rubber block 205 will be squeezed with the inner edge of the upper side of the oil tank 6, so that the rubber block 205 drives the movable plate 201 to rotate in the opposite direction of the rotational offset, and drives the hanging frame 1 and the transformer 5 to rotate in the opposite direction of the rotational offset, so that all the rubber blocks 205 are in contact with the inner edge of the upper side of the oil tank 6, and the transformer 5 is guided, so that the transformer 5 and the oil tank 6 are accurately aligned, which prevents the transformer 5 from rotating and deviating when being placed in the oil tank 6, and avoids the transformer 5 and the upper side of the oil tank 6 from colliding with each other, thereby enhancing the protection effect of the transformer 5 and the oil tank 6 during installation.

[0047] When the transformer 5 and the oil tank 6 are aligned and aligned, the control hoisting frame 1 drives the movable plate 201 and the guide block 203 to continue to descend, and the guide block 203 and the rubber block 205 are squeezed by the upper side of the oil tank 6 and gradually rotate upward to the position shown in FIG. Figure 7 In the tilted state shown, the hanging frame 1 is fixed to the oil tank 6 to enhance the stabilizing effect on the transformer 5, and then the two telescopic ends of the second driving member 208 are controlled to retract at the same time, driving the two adjacent insertion rods 206 on the left and right to be pulled out from the corresponding upper plug holes 20101 of the movable plate 201, and then the hanging frame 1 is controlled to drive the transformer 5 to continue to descend, and the rubber block 205 is stuck on the upper side of the oil tank 6 to limit the movable plate 201, so that the hanging frame 1 drives the transformer 5 to move downward on the movable plate 201, so that the transformer 5 enters the interior of the oil tank 6 and compresses the elastic member 207. When the rubber block 205 is squeezed and deformed by the lower side of the transformer 5, when the transformer 5 moves downward and passes through the rubber block 205, the rubber block 205 rebounds and resets to make the notch 20501 clamp the support rod 5002, so that the support rod 5002 moves downward in the notch 20501 along with the transformer 5. The notch 20501 is used to squeeze and limit the support rod 5002 during the downward movement of the transformer 5, so as to prevent the transformer 5 from rotating and deviating when entering the oil tank 6, and to avoid the transformer 5 and the inner wall of the oil tank 6 from wearing and bumping against each other, thereby further enhancing the protection effect of the transformer 5 and the oil tank 6 during installation.

[0048] When the hanging frame 1 moves down to a position lower than the lower plug hole 20101 of the movable plate 201, the sensor provided on the plug rod 206 identifies the lower plug hole 20101 of the movable plate 201, controls the two telescopic ends of the second driving member 208 to extend simultaneously, drives the two adjacent plug rods 206 on the left and right to insert into the corresponding lower plug holes 20101 of the movable plate 201, and fixes the movable plate 201. At this time, the support rod 5002 moves down with the transformer 5 and passes through the notch 20501, so that the rubber block 205 contacts the lower side of the transformer 5 cover plate, stabilizes the transformer 5, and prevents the transformer 5 from deflecting. Then, the extension of the first driving member 204 is controlled. The retracted end extends out, driving the moving block 202 to slide in the sliding groove on the movable plate 201 toward the side away from the oil tank 6, and then driving the guide block 203 and the rubber block 205 to move to the outside of the oil tank 6, so that the guide block 203 and the rubber block 205 are pulled out from between the transformer 5 and the oil tank 6, and then the hanging frame 1 is controlled to drive the transformer 5 to continue to move downward, and the transformer 5 is installed on the oil tank 6. At this time, the two telescopic ends of the second driving member 208 are controlled to retract at the same time, driving the two adjacent insertion rods 206 on the left and right to be pulled out from the corresponding lower plug holes 20101 of the movable plate 201, and the movable plate 201 moves downward on the hanging frame 1 to the position as shown in the figure under the elastic force of the elastic member 207. Figure 6 Then, the second driving member 208 is controlled to drive the insertion rod 206 to be inserted into the corresponding upper plug hole 20101 of the movable plate 201 to fix the movable plate 201, and at the same time, the telescopic end of the first driving member 204 is controlled to retract, driving the moving block 202, the guide block 203 and the rubber block 205 to move to the state shown in FIG. Figure 6 The status shown is ready for the next installation work.

[0049] Example 3

[0050] On the basis of Examples 1 and 2, Figure 1 , Figure 2 and Figure 8 As shown, a synchronization system is also included, and the synchronization system includes a connecting frame 301; a connecting frame 301 is fixedly connected between each two adjacent movable plates 201.

[0051] The synchronization system also includes a rotating rod 302 and a sliding block 303; each guide block 203 is rotatably connected to a rotating rod 302; the rotating rod 302 is L-shaped; each connecting frame 301 is provided with a sliding groove 30101; each sliding groove 30101 is slidably connected to a sliding block 303; each sliding block 303 is rotatably connected to two adjacent rotating rods 302.

[0052] The calibration system further includes a connecting rod 304 ; a connecting rod 304 is fixedly connected between each two adjacent guide blocks 203 on the left and right.

[0053] Since the weight of individual components on the transformer 5 is different and the position distribution is irregular, the center of gravity of the transformer 5 is biased to one side. When the transformer 5 with the center of gravity biased to one side is hoisted, when the guide block 203 is squeezed by the oil tank 6, the extrusion force on the guide block 203 close to the center of gravity of the transformer 5 is greater than the extrusion force on other guide blocks 203, and the upward rotation angle of the guide block 203 close to the center of gravity of the transformer 5 is greater than the rotation angle of other guide blocks 203. The present invention uses the rotating rod 302 and the connecting rod 304 to make each guide block rotate synchronously, solving the problem that the rotation angle of each guide block 203 on the corresponding moving block 202 is inconsistent due to uneven force, resulting in the tilt of the hoisting frame 1 and the transformer 5. The specific process is as follows:

[0054] When the guide block 203 on the side close to the center of gravity of the transformer 5 is squeezed by the oil tank 6 and rotates upward, the guide block 203 approaches the middle of the oil tank 6, driving the rotating rod 302 to move upward, and the rotating rod 302 lifts the sliding block 303 upward in the sliding groove 30101, and drives the other rotating rod 302 to move upward through the sliding block 303, and then drives the other guide block 203 to rotate toward the middle of the oil tank 6, so that the two front and rear opposite guide blocks 203 rotate synchronously toward the middle of the oil tank 6. At the same time, the two left and right adjacent guide blocks 203 are synchronously rotated toward the middle of the oil tank 6 through the connecting rod 304, so that the rotation angles of all guide blocks 203 rotate with the guide block 203 with the greatest pressure, and then the rotation angles of each guide block 203 are kept consistent, which is conducive to keeping the hoisting frame 1 and the transformer 5 stable before entering the oil tank 6, preventing the transformer 5 from tilting, and avoiding the transformer 5 from colliding with the oil tank 6, further enhancing the protection effect of the transformer 5 and the oil tank 6.

[0055] When the movable plate 201 is squeezed by the oil tank 6 to move upward on the hanging frame 1, the two movable plates 201 opposite to each other at the front and rear are moved upward synchronously through the connecting frame 301, so that the hanging frame 1 and the transformer 5 remain in a stable state when entering the oil tank 6, further enhancing the protection effect on the transformer 5 and the oil tank 6.

[0056] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the appended claims of the application.
