Description

Technical Field

[0001] The utility model relates to the technical field of transformer installation, in particular to a multi-voltage compatible dry-type transformer installation and lifting device. Background Art

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil; the cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When the transformer is naturally cooled, it can operate continuously for a long time at rated capacity. When forced air cooling, the transformer output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be in long-term continuous overload operation.

[0003] In the prior art, in the process of installing dry-type transformers, most of them are traditional lifting machinery. Traditional lifting machinery is often large in size and cannot be used in some areas with narrow spaces or roads. There are certain requirements for the installation space, which leads to some transformers that need to be installed in narrow streets having to be installed by manual lifting. Manual lifting is not only time-consuming and labor-intensive, but also prone to danger during the lifting process. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a multi-voltage compatible dry-type transformer installation lifting device, which has a simple structure, adopts a mechanical structure to replace manual labor, reduces the volume of the lifting device, makes it convenient to use in a small space, and improves the installation efficiency of the transformer.

[0005] The utility model discloses a multi-voltage compatible dry-type transformer installation and lifting device, comprising a base, a rotating disk rotatably installed on the base, a lifting mechanism provided on the rotating disk, a placement plate fixedly connected to the base, and clamping mechanisms provided on four directions of the placement plate;

[0006] The clamping mechanism comprises a long hole formed on the placement plate, a moving mechanism arranged below the long hole, an output end of the moving mechanism being a moving plate, and the moving plate being slidably connected to a clamping plate;

[0007] The clamping mechanism also includes a fixed shaft fixed on the clamping plate and a guide plate fixed on the bottom of the placement plate, the guide plate is provided with a through hole, the through hole includes an inclined section, and the fixed shaft passes through the inclined section;

[0008] There is an angle between the inclined section and the moving track of the moving plate.

[0009] Furthermore, the through hole further comprises a horizontal section connected to one end of the inclined section, and the horizontal section is parallel to the moving track of the moving plate;

[0010] When the fixed shaft is located at an end of the inclined section away from the horizontal section, the top end of the clamping plate does not protrude from the long strip hole.

[0011] Furthermore, the moving mechanism comprises two bearing seats fixedly connected to the bottom of the moving plate, the bearing seats are rotatably connected to a screw rod, and the screw rod is threadedly connected to the moving plate;

[0012] The moving mechanism also includes an optical axis fixedly connected to the two bearing seats, and the optical axis is slidably connected to the moving plate;

[0013] A hand wheel is installed at the end of the screw rod.

[0014] Furthermore, the lifting mechanism comprises a bracket fixedly connected to the rotating disk, the bracket is rotatably connected to the oil cylinder 1, the output end of the oil cylinder 1 is rotatably connected to one end of the rotating frame, and the other end of the rotating frame is rotatably connected to the bracket;

[0015] The rotating frame is fixedly connected to the oil cylinder 2, and a hook is installed at the output end of the oil cylinder 2.

[0016] Furthermore, the rotating disk is rotatably connected to the base via a rotating disk bearing.

[0017] Furthermore, universal wheels are evenly distributed on the bottom of the base.

[0018] Furthermore, a handle is installed at the end of the base.

[0019] Furthermore, the fixed shaft is fixedly connected to the bearing, and the outer ring of the bearing is in contact with the inner wall of the through hole.

[0020] Compared with the prior art, the utility model has the following beneficial effects: when in use, before lifting, the moving mechanism is operated to make the fixed axis be on the end of the inclined section away from the horizontal section, and the top of the clamping plate does not protrude from the long strip hole. Then the dry-type transformer is lifted by the lifting mechanism. If the dry-type transformer needs to be moved, in order to improve the stability and prevent the dry-type transformer from shaking during movement, causing the base to tip over, the lifting mechanism is operated to place the dry-type transformer on the placement plate and between the four long strip holes. The clamping mechanism is operated to limit the dry-type transformer in four directions, which plays a role in fixing the dry-type transformer, thereby affecting the stability of the base. After the dry-type transformer is placed on the placement plate, according to the position of the bottom end of the dry-type transformer , operate the four moving mechanisms to move the moving plate and the clamping plate toward the dry-type transformer. When the fixed shaft passes through the inclined section, the clamping plate is slidably connected to the moving plate, and the fixed shaft fixedly connected to the clamping plate passes through the inclined section, and there is an angle between the inclined section and the moving trajectory of the moving plate. Therefore, when the moving plate moves, the clamping plate moves horizontally and vertically at the same time. After the fixed shaft moves to the horizontal section, the top of the clamping plate protrudes from the top of the placement plate, and then the moving mechanism is continued to be operated to move the moving plate, and the fixed shaft moves along the horizontal section. Since the horizontal section is parallel to the moving trajectory of the moving plate, it will not affect the height of the clamping plate, until the clamping plate contacts the bottom end of the dry-type transformer.

DETAILED DESCRIPTION

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figures 1 to 3As shown, the multi-voltage compatible dry-type transformer installation and lifting device of the utility model comprises a base 1, a rotating disk 2 is rotatably installed on the base 1, the rotating disk 2 is provided with a lifting mechanism, and the base 1 is also fixedly connected with a placement plate 3, and clamping mechanisms are provided on four directions of the placement plate 3;

[0028] The clamping mechanism further includes a fixed shaft 7 fixed on the clamping plate 6 and a guide plate 8 fixed on the bottom of the placement plate 3. The guide plate 8 is provided with a through hole, and the through hole includes an inclined section 9. The fixed shaft 7 passes through the inclined section 9.

[0030] Furthermore, the through hole further includes a horizontal section 10 connected to one end of the inclined section 9, and the horizontal section 10 is parallel to the moving track of the moving plate 5;

[0031] When the fixed shaft 7 is at the end of the inclined section 9 away from the horizontal section 10, the top end of the clamping plate 6 does not protrude from the long hole 4;

[0032] In this embodiment, when in use, before lifting, the moving mechanism is operated to make the fixed shaft 7 be on the end of the inclined section 9 away from the horizontal section 10, and the top of the clamping plate 6 does not protrude from the long hole 4, and then the dry-type transformer is lifted by the lifting mechanism. If the dry-type transformer needs to be moved, in order to improve stability and prevent the dry-type transformer from shaking during movement, causing the base 1 to tip over, the lifting mechanism is operated to place the dry-type transformer on the placement plate 3 and between the four long holes 4, and the clamping mechanism is operated to limit the dry-type transformer in four directions, which plays a role in fixing the dry-type transformer, thereby affecting the stability of the base 1. After the dry-type transformer is placed on the placement plate 3, the moving mechanism is operated to make the moving plate 5 and The clamping plate 6 moves toward the dry-type transformer. When the fixed shaft 7 passes through the inclined section 9, since the clamping plate 6 is slidably connected to the movable plate 5, and the fixed shaft 7 fixedly connected to the clamping plate 6 passes through the inclined section 9, and there is an angle between the inclined section 9 and the moving trajectory of the movable plate 5, when the movable plate 5 moves, the clamping plate 6 moves horizontally and vertically at the same time. After the fixed shaft 7 moves to the horizontal section 10, the top of the clamping plate 6 protrudes from the top of the placement plate 3, and then the moving mechanism continues to be operated to move the movable plate 5, and the fixed shaft 7 moves along the horizontal section 10. Since the horizontal section 10 is parallel to the moving trajectory of the movable plate 5, it will not affect the height of the clamping plate 6 until the clamping plate 6 contacts the bottom end of the dry-type transformer.

[0033] Furthermore, the moving mechanism includes two bearing seats 11 fixedly connected to the bottom of the moving plate 5, the bearing seats 11 are rotatably connected to a screw rod 12, and the screw rod 12 is threadedly connected to the moving plate 5;

[0034] The moving mechanism further includes an optical axis 13 fixedly connected to the two bearing seats 11, and the optical axis 13 is slidably connected to the moving plate 5;

[0035] A hand wheel 14 is mounted on the end of the screw rod 12;

[0036] In this embodiment, the hand wheel 14 is rotated to rotate the screw rod 12 . Since the screw rod 12 is threadedly connected to the moving plate 5 , and the optical axis 13 is slidably connected to the moving plate 5 , the moving plate 5 is moved by rotating the hand wheel 14 .

[0037] Furthermore, the lifting mechanism includes a bracket 15 fixedly connected to the rotating disk 2, the bracket 15 is rotatably connected to a cylinder 16, the output end of the cylinder 16 is rotatably connected to one end of a rotating frame 17, and the other end of the rotating frame 17 is rotatably connected to the bracket 15;

[0038] The rotating frame 17 is fixedly connected to the oil cylinder 18, and a hook 19 is installed at the output end of the oil cylinder 18;

[0039] In this embodiment, the oil cylinder 16 is approximately in a vertical state, and the oil cylinder 2 18 is approximately in a horizontal state. Through the cooperation between the oil cylinder 16 and the oil cylinder 2 18, the height and horizontal position of the hook 19 can be controlled.

[0040] Furthermore, the rotating disk 2 is rotatably connected to the base 1 via a rotating disk bearing 20;

[0041] In this embodiment, the rotating disk 2 is rotatably connected to the base 1 via a turntable bearing 20, so that the entire rotating disk 2 and the lifting mechanism can rotate relative to the base 1, thereby increasing the lifting range.

[0042] Furthermore, universal wheels 21 are evenly distributed on the bottom of the base 1;

[0043] In this embodiment, the universal wheels 21 are provided to improve the mobility of the entire device.

[0044] Furthermore, a handle 22 is installed at the end of the base 1;

[0045] In this embodiment, by providing the handle 22, when moving the device, the user can hold the handle 22 to move the device, which provides a better force point.

[0046] Furthermore, the fixed shaft 7 is fixedly connected to the bearing, and the outer ring of the bearing is in contact with the inner wall of the through hole;

[0047] In this embodiment, by installing a bearing on the fixed shaft 7, the wear on the fixed shaft 7 is reduced.

[0048] The multi-voltage compatible dry-type transformer installation and lifting device of the utility model, when in use, before lifting, rotate the hand wheel 14 to make the fixed shaft 7 be on the end of the inclined section 9 away from the horizontal section 10, and the top of the clamping plate 6 does not protrude from the long strip hole 4, and then lift the dry-type transformer through the lifting mechanism. If the dry-type transformer needs to be moved, in order to improve the stability and prevent the dry-type transformer from shaking during movement, causing the base 1 to tip over, operate the rotating disk 2, the oil cylinder 16 and the oil cylinder 2 18 to place the dry-type transformer on the placement plate 3 and between the four long strip holes 4;

[0049] The hand wheel 14 is rotated to limit the dry-type transformer in four directions, which plays a role in fixing the dry-type transformer, thereby affecting the stability of the base 1. After the dry-type transformer is placed on the placement plate 3, according to the position of the bottom end of the dry-type transformer, the hand wheel 14 is rotated to make the movable plate 5 and the clamping plate 6 move toward the dry-type transformer. When the fixed shaft 7 passes through the inclined section 9, since the clamping plate 6 is slidably connected with the movable plate 5, and the fixed shaft 7 fixedly connected to the clamping plate 6 passes through the inclined section 9, and there is an angle between the inclined section 9 and the moving trajectory of the movable plate 5, when the movable plate 5 moves, the clamping plate 6 moves horizontally and vertically at the same time. After the fixed shaft 7 moves to the horizontal section 10, the top end of the clamping plate 6 protrudes from the top end of the placement plate 3, and then the hand wheel 14 is continued to be rotated to move the movable plate 5, and the fixed shaft 7 moves along the horizontal section 10. Since the horizontal section 10 is parallel to the moving trajectory of the movable plate 5, it will not affect the height of the clamping plate 6 until the clamping plate 6 contacts the bottom end of the dry-type transformer.

[0050] Then hold the handle 22 to move the device.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
