Abstract
Description
Technical Field
[0001] The invention relates to the technical field of transformer installation, and in particular to an auxiliary bracket for transformer installation. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.
[0003] Most transformers are installed outdoors, such as between two electric poles. When installing such a transformer, it is usually necessary to manually climb up to two adjacent electric poles, and then use lifting equipment to lift the brackets to the designated positions on the electric poles in turn and assemble them. Finally, the transformer is lifted and fixed to the assembled brackets by lifting equipment. In this process, large equipment such as cranes are needed for auxiliary installation. Before installing the transformer, construction workers need to do a lot of measurement work. During the installation process, construction workers need to level the supporting devices such as cross arms according to construction standards when installing supporting devices.

DETAILED DESCRIPTION
[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0034] Reference Figure 1-9, an auxiliary bracket for transformer installation, comprising two electric poles 1, each of which is movably mounted with a clamp 3, a cross arm 2 is arranged between the two electric poles 1 on both sides of the clamp 3, the cross arm 2 is movably connected to the corresponding position on the clamp 3, a transformer body 4 is arranged above the two cross arms 2, two symmetrically arranged pins 10 are fixedly mounted on the bottom surface of the transformer body 4, four symmetrically arranged hanging ears 5 are fixedly mounted on the upper end surface of the transformer body 4, a movable moving component 6 is arranged outside the two electric poles 1, and an extended support plate 7 is fixedly mounted on both sides of the moving component 6, and the upper end surface of the two extended support plates 7 is fixedly mounted with a movable moving component 6. A lifting assembly 8 is fixedly installed on the surface, and a lifting platform 9 is also fixedly installed on the upper surfaces of the two extension support plates 7. The lifting platform 9 specifically includes two hydraulic lifts 901 fixedly installed on the upper surface of the extension support plate 7. An operating platform 902 is fixedly installed on the output ends of the two hydraulic lifts 901, and the lifting assembly 8 is arranged inside the operating platform 902. The operating platform 902 is U-shaped, and second extension blocks 904 are fixedly installed on both sides of the operating platform 902. A second adjustment assembly 15 is fixedly installed between the upper ends of the second extension blocks 904 distributed at both ends of the operating platform 902;
[0035] The second adjustment assembly 15 includes an electric slide rail 1501 whose two ends are fixedly connected to the upper end of the second extension block 904, an electric slide table 1502 is slidably mounted on the electric slide rail 1501, an auxiliary plate 1503 is rotatably mounted on the outside of the electric slide table 1502, the middle section of the auxiliary plate 1503 is rotatably connected to the electric slide table 1502, a guide plate 1504 is rotatably mounted on one side of the auxiliary plate 1503, and a stopper 1508 is fixedly mounted on the other end of the auxiliary plate 1503 away from the guide plate 1504;
[0036] The lifting assembly 8 includes a fixed frame 801 fixedly connected to the upper surface of the extension support plate 7, and two symmetrically arranged first extension blocks 805 are fixedly installed on the upper outer wall of the upper end of the fixed frame 801. Lifting blocks 806 are fixedly installed on the upper surfaces of the ends of the two first extension blocks 805. A rotating shaft 807 is rotatably installed between the two lifting blocks 806, and two symmetrically arranged winches 808 are fixedly installed on the rotating shaft 807. The outer wall of the winch 808 is fixedly connected to a traction rope 811, and the number of traction ropes 811 fixedly connected to the same winch 808 is two.
[0037] Before installing the transformer body 4, the relevant power construction workers pre-buried and fixed the two utility poles 1. Then, the workers can move the mobile component 6 between the two utility poles 1, and clamp the lower ends of the utility poles 1 through the expandable reinforcement clamps 16 installed on the support plates 7 extending on both sides of the mobile component 6, so as to fix the mobile component 6. Then, the construction workers can climb to the upper surface of the operating platform 902 through multiple foot pedals 12. Before that, the construction workers can place the cross arm 2 and the clamp 3 and other parts on the upper surface of the operating platform 902 in advance. Then, the construction workers can rotate the auxiliary plate 1503 so that the auxiliary plate 1503 is rotated to the position where the block is installed. The outer wall of one side of 1508 is horizontally upward. When the two auxiliary plates 1503 are rotated to the horizontal, the construction personnel can adjust the auxiliary plates 1503 to the preset height, and then place the two cross arms 2 on the upper surface of the auxiliary plates 1503. The two cross arms 2 can be pre-supported by the two auxiliary plates 1503. Then, according to the preset positions of the two cross arms 2, the construction personnel can fix the clamps 3 on the two electric poles 1 respectively, wherein the upper surface of the clamps 3 contacts the bottom surface of the cross arms 2, and the two ends of the two cross arms 2 can be supported by the clamps 3, and the cross arms 2 and the clamps 3 are fixed by bolts and other fasteners, so that the two ends of the cross arms 2 and the clamps 3 are stably connected;When the transformer body 4 is pulled to move upward, the construction personnel can adjust the auxiliary plate 1503 to an inclined state in advance, and the two guide plates 1504 rotatably installed on the auxiliary plate 1503 are also in an inclined state. At this time, by controlling the electric slide 1502 to slide on the electric slide rail 1501, the positions of the two auxiliary plates 1503 correspond to the two pins 10 set on the bottom surface of the transformer body 4. In the process of the transformer body 4 moving upward, the upper edge of the transformer body 4 contacts the outer wall of the auxiliary plate 1503. The auxiliary plate 1503 in an inclined state moves along the surface of the auxiliary plate 1503 in the process of contacting the transformer body 4 to prevent the transformer body 4 from shaking back and forth. In the process of the transformer body 4 continuing to move upward, both sides of the upper surface of the transformer body 4 are in contact with the two inclined guide plates 1504 at the same time. The two inclined guide plates 1504 are symmetrically arranged. During the process, the transformer body 4 is adjusted to the center position of the cross arm 2. During the continuous upward movement of the transformer body 4, the two sides of the upper surface of the transformer body 4 interact with the two guide plates 1504 until the two guide plates 1504 are pushed to be parallel to and in contact with the outer walls of the two sides of the transformer body 4. When the bottom surface of the transformer body 4 is pulled to be higher than the upper surface of the cross arm 2, the transformer body 4 can be moved horizontally by changing the force position of the pulling rope 811. When the transformer body 4 moves horizontally, the bottom surface of the transformer body 4 contacts the outer wall of the auxiliary plate 1503. At this time, the auxiliary plate 1503 also rotates to a horizontal state accordingly, wherein the multiple rotating rollers 1505 rotatably installed on the outer wall of the auxiliary plate 1503 can assist the transformer body 4 to move horizontally, and when the transformer body 4 moves horizontally along the surface of the auxiliary plate 1503, the guide plates 1504 set on the two auxiliary plates 1503 can continuously limit the transformer body 4 to prevent the transformer body 4 from deviating in the left and right directions. ;
[0038] As a technical optimization solution of the present invention, a rectangular groove is provided on the auxiliary plate 1503, and a plurality of rotating rollers 1505 are rotatably installed inside the rectangular groove. A round shaft is fixedly installed at the end of the guide plate 1504, and the guide plate 1504 is rotatably connected to the corresponding position on the auxiliary plate 1503 through the round shaft. A ratchet 1506 is fixedly installed at the end of the round shaft, and a ratchet 1507 used in conjunction with the ratchet 1506 is rotatably connected to the auxiliary plate 1503.
[0039] The setting of multiple rotating rollers 1505 can convert the sliding friction between the bottom surface of the transformer main body 4 and the outer wall of the auxiliary plate 1503 into rolling friction when the bottom surface of the transformer main body 4 contacts the outer wall of the auxiliary plate 1503, which makes it easier to adjust the position of the transformer main body 4. The ratchet 1506 and the pawl 1507 arranged at the end of the guide plate 1504 can limit the guide plate 1504 when the guide plate 1504 is squeezed to be parallel to the side wall of the transformer main body 4, so as to prevent the guide plate 1504 from rotating when it is not in contact with the transformer main body 4. When the device is used to assist in the installation of the next transformer main body 4, the construction personnel can manually rotate the guide plate 1504 clockwise to make it in an inclined state.
[0040] As a technical optimization solution of the present invention, a fixed shaft 809 is fixedly installed between the ends of the first extension block 805, and a guide block 810 is fixedly installed on the fixed shaft 809 below the winch 808. The cross section of the guide block 810 is triangular, and two traction ropes 811 are respectively in contact with the outer walls on both sides of the guide block 810. The ends of the two traction ropes 811 are fixedly connected with hooks 812, and the hooks 812 are movably connected to the hanging ears 5.
[0041] In this structure, the fixing frame 801 is set in an inverted U shape as a whole. By driving the rotating shaft 807 set at the upper end of the fixing frame 801 to rotate, the winch 808 fixedly installed on the rotating shaft 807 can be driven to rotate. Then the winch 808 can wind or release the traction rope 811 by rotating, so as to control the length of the traction rope 811. The guide block 810 fixedly installed on the fixed shaft 809 is set in a triangular shape as a whole. A rectangular frame is fixedly installed on the upper end of the guide block 810. The setting of the guide block 810 can make the two traction ropes 811 below the guide block 810 in a separated state, and the two traction ropes 811 above the guide block 810 in a closed state. The hook 812 set at the end of the traction rope 811 is hung with the hanging ear 5. When the traction rope 811 is wound and shortened, the transformer body 4 can be pulled upward. The hanging ears 5 are respectively distributed at four symmetrically arranged positions on the upper surface of the transformer body 4. The four traction ropes 811 can stably pull the transformer body 4 upward.

[0043] The driving gear 802 arranged on the fixed frame 801 is driven to rotate by an external motor. Under the action of the synchronous belt 803, the driving gear 802 can drive the driven gear 804 to rotate. This structural arrangement can ensure the normal rotation of the driven gear 804 while avoiding the overall mass of the various structures arranged at the end of the first extension block 805 being too large, thereby affecting the position of the center of gravity of the entire device.
[0044] As a technical optimization solution of the present invention, a first adjustment component 14 is arranged inside the fixing frame 801, and the first adjustment component 14 includes a mounting plate 1401 fixedly connected to the fixing frame 801, a second electric telescopic rod 1402 is fixedly installed at the middle position of the mounting plate 1401, a sliding slot 1403 is fixedly installed at the output end of the second electric telescopic rod 1402, and two groups of symmetrically arranged limit frames 1404 are slidably installed on the sliding slot 1403, the limit frames 1404 are of a circular structure, and movable blocks 1405 are slidably installed at both ends of the limit frames 1404; through the extension and shortening of the second electric telescopic rod 1402, the limit frames 1404 can adjust the The traction rope 811 applies force, thereby changing the position of the hook 812 set at the end of the traction rope 811. Under the coordinated adjustment of the second electric telescopic rod 1402 and the limit frame 1404, the traction rope 811 can be used to pull the transformer body 4 to move vertically upward at the specified position, and the traction rope 811 can also be used to pull the transformer body 4 to move horizontally until the transformer body 4 is placed on the upper surface of the cross arm 2 to be installed. After the installation of the transformer body 4 is completed, when part of the traction rope 811 is released so that the traction rope 811 is in a relaxed state as a whole, the hook 812 can be separated from the hanging ear 5 by sliding the movable block 1405, thereby causing the hook 812 to automatically unhook.
[0045] As a technical optimization solution of the present invention, positioning components 13 are slidably installed on both sides of the interior of the fixed frame 801, and the positioning component 13 includes a first electric telescopic rod 1301 slidably connected to the fixed frame 801, and a positioning fork 1302 is fixedly installed on the output end of the first electric telescopic rod 1301, and the positioning fork 1302 is T-shaped; an electric slider is fixedly installed on one end of the first electric telescopic rod 1301, and the positioning component 13 as a whole can slide up and down along the fixed frame 801 under the action of the electric slider, and the height of the positioning component 13 can be adjusted according to the size of the transformer body 4, and in actual application, the T-shaped positioning fork 1302 can be respectively clamped on the two side edges on the same side of the transformer body 4, so that the installation position of the transformer body 4 can be positioned, so that the hole position opened on the pin 10 on the bottom surface of the transformer body 4 accurately corresponds to the installation position on the cross arm 2.

If the wedge-shaped seat 602 is not flipped over, one end of the wedge-shaped seat 602 is placed on the step block 604 to ensure the supporting strength of the wedge-shaped seat 602. At this time, the construction personnel can also place the transformer body 4 on the upper surface of the wedge-shaped seat 602 that has not been flipped over.
[0048] As a technical optimization solution of the present invention, an installation groove is opened on the outer wall of one side of the extended support plate 7, and a reinforcing clamp 16 is movably connected inside the installation groove; the reinforcing clamp 16 is a common electric clamp in the prior art, and the reinforcing clamp 16 is opened to clamp the lower end of the pole 1, which can limit the position of the movable component 6 and the extended support plate 7, and also makes the entire device more stable and safer.

The two cross arms 2 can be pre-supported by the two auxiliary plates 1503. Then, according to the preset positions of the two cross arms 2, the construction personnel can fix the clamps 3 on the two electric poles 1 respectively, wherein the upper surface of the clamps 3 contacts the bottom surface of the cross arms 2, and the two ends of the two cross arms 2 can be supported by the clamps 3, and the cross arms 2 and the clamps 3 are fixed by bolts and other fasteners, so that the two ends of the cross arms 2 and the clamps 3 are stably connected;
[0051] Next, the construction personnel can move the transformer body 4 to the mobile assembly 6 and place it thereon, wherein the overall height of the mobile assembly 6 can be lowered by flipping the wedge-shaped seat 602, and the special structure of the wedge-shaped seat 602 can also assist the transformer body 4 to move to the upper surface of the base 601. When the transformer body 4 is on the base 601, the construction personnel can control the driving gear 802 to rotate, and under the action of the synchronous belt 803, the synchronous belt 803 can drive the driven gear 804 to rotate. When the driven gear 804 rotates, the rotating shaft 807 fixedly connected to the driven gear 804 rotates coaxially, thereby causing the two winches 808 to rotate. At this time, the traction rope 811 wound on the winch 808 is released and becomes longer, and the construction personnel can rotate the driven gear 804. Under the action of the motor assistance, the hooks 812 arranged at the ends of the four traction ropes 811 are respectively hung on the hanging ears 5. In the subsequent process, the traction ropes 811 are rolled up by driving the winch 808 in the reverse direction, so that the transformer body 4 can be hoisted upward as a whole. In the process of pulling the transformer body 4 upward, the position of the traction rope 811 is adjusted by shortening the output end of the second electric telescopic rod 1402. After the second electric telescopic rod 1402 is shortened, the transformer body 4 can be moved vertically upward from the outside of a cross arm 2 close to the lifting component 8 under the action of the limit frame 1404. When the transformer body 4 is pulled upward, the construction personnel can adjust the auxiliary plate 1503 to an inclined state (such as Figure 4As shown in the figure, the two guide plates 1504 rotatably mounted on the auxiliary plate 1503 are also in an inclined state. At this time, by controlling the electric slide 1502 to slide on the electric slide rail 1501, the positions of the two auxiliary plates 1503 correspond to the two pins 10 set on the bottom surface of the transformer main body 4. During the upward movement of the transformer main body 4, the upper edge of the transformer main body 4 contacts the outer wall of the auxiliary plate 1503. The auxiliary plate 1503 in an inclined state moves along the surface of the auxiliary plate 1503 during the contact with the transformer main body 4 to prevent the transformer main body 4 from shaking back and forth. In the process of the transformer main body 4 continuing to move upward, both sides of the upper surface of the transformer main body 4 simultaneously contact the two inclined guide plates 1504. The two inclined guide plates 1504 are symmetrically arranged. Therefore, under the action of the two guide plates 1504, the transformer main body 4 can be adjusted to the center position of the cross arm 2 during the upward movement of the transformer main body 4. During the upward movement, the two sides of the upper surface of the transformer body 4 interact with the two guide plates 1504 until the two guide plates 1504 are pushed to be parallel to and in contact with the outer walls on both sides of the transformer body 4. When the bottom surface of the transformer body 4 is pulled to be higher than the upper surface of the cross arm 2, the output end thereof is extended by adjusting the second electric telescopic rod 1402, and the force position of the traction rope 811 can be changed to make the transformer body 4 move horizontally. When the transformer body 4 moves horizontally, the bottom surface of the transformer body 4 contacts the outer wall of the auxiliary plate 1503. At this time, the auxiliary plate 1503 also rotates to a horizontal state accordingly, wherein the multiple rotating rollers 1505 rotatably installed on the outer wall of the auxiliary plate 1503 can assist the transformer body 4 in moving horizontally, and when the transformer body 4 moves horizontally along the surface of the auxiliary plate 1503, the guide plates 1504 arranged on the two auxiliary plates 1503 can continuously limit the transformer body 4 to prevent the transformer body 4 from shifting in the left and right directions.
[0052] When the transformer body 4 moves horizontally along the surface of the auxiliary plate 1503, the construction personnel can adjust the position of the positioning fork 1302 in advance according to the size of the transformer body 4. When the transformer body 4 moves to the outer wall and contacts the positioning fork 1302, the positioning fork 1302 limits the two sides of the transformer body 4, which can ensure that the hole position on the pin 10 set on the bottom surface of the transformer body 4 is accurately corresponding to the installation hole position on the cross arm 2. In this process, the positioning forks 1302 set on both sides of the transformer body 4 can reversely detect whether the transformer body 4 is in the center position on the cross arm 2.
[0053] Next, the transformer body 4 is further pulled upward by the traction rope 811 so that the bottom surface of the transformer body 4 is not in contact with the auxiliary plate 1503. When the bottom surface of the transformer body 4 is separated from the auxiliary plate 1503, the electric slide 1502 slides on the electric slide rail 1501. When the auxiliary plate 1503 moves to make way, the traction rope 811 is released to place the transformer body 4 on the upper surface of the crossarm 2. At this time, the transformer body 4 is placed in the center position of the upper surfaces of the two crossarms 2, and the holes opened on the pins 10 correspond to the installation holes on the crossarm 2. The construction personnel are on the upper surface of the operating platform 902 and connect and fix the pins 10 to the crossarm 2 through fasteners to complete the installation of the transformer body 4 on the crossarm 2. In the subsequent process, the construction personnel can still stand on the upper surface of the operating platform 902 to complete the connection of various cables on the transformer.
