Description

Technical Field

[0001] The invention relates to the technical field of transformer installation, and in particular to a method for using a transformer mounting frame. 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] Transformers can be divided into power transformers and special transformers according to their uses. Before the transformer is transported to the installation site, the construction of the transformer installation foundation should be completed. Transformers are usually installed at high places, which provides good protection for the transformer and passers-by around, reducing external damage to the transformer and electric shock to people around the transformer.

[0004] However, the existing high-rise outdoor transformers still have some shortcomings. First, the existing transformers are installed at high altitudes, and workers have extremely high environmental requirements when installing at high altitudes. If there is bad weather, the danger to the workers will increase. Secondly, the transformers are usually installed in relatively remote fields, and the field roads are usually rugged and not convenient for the lifting vehicle to travel, which is not conducive to the maintenance of the transformer. Therefore, a bracket that can facilitate the installation and maintenance of the transformer is needed. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, a method for using a transformer mounting frame is provided.

[0006] The technical solution adopted by the present invention to solve the technical problem is:

[0007] The present invention proposes a transformer mounting frame, comprising a foundation, wherein the foundation is fixedly connected to a vertically arranged electric pole, a bracket is slidably arranged between the electric poles, the bracket is connected to a lifting mechanism, and a transformer is detachably connected to the bracket; a rack is arranged on one side of the electric pole, a circular wire is sleeved on the electric pole, and the circular wire is rotatably connected to the bracket; a plurality of claw blocks are cooperatively arranged on the upper end surface of the circular wire, a gear ring is arranged on the lower end surface of the circular wire, the rack is meshed with the gear ring through a gear reducer, and the gear reducer is connected to the bracket.

[0008] Preferably, the claw block and the rack are staggered.

[0009] Preferably, a plurality of claw blocks are annularly sleeved on the outside of the electric pole, and in an initial state, a gap is left between the claw blocks and the electric pole.

[0010] Preferably, the gear reducer includes a third gear, the bracket is fixedly connected to a fixed block, the third gear is rotatably connected to the fixed block, the third gear is coaxially connected to the second gear, and the third gear is meshed with the rack.

[0011] Preferably, the fixing block is also rotatably connected to a first gear, the first gear is coaxially connected to a bevel gear, the bevel gear is meshed with the ring gear, and the first gear is meshed with the second gear; the diameter of the first gear is greater than the diameter of the second gear.

[0012] Preferably, the lifting mechanism includes a plurality of screw rods, a fixing frame is fixedly connected between the electric poles, the screw rod is rotatably connected to the fixing frame, a nut is provided on the screw rod, and the nut is fixedly connected to the bracket; the fixing frame is also connected to a limit rod arranged in the vertical direction, and the nut is slidably connected to the limit rod.

[0013] Preferably, the fixed frame is rotatably connected to a rotating shaft arranged in a horizontal direction, the rotating shaft is connected to a worm, a worm wheel is fixedly sleeved on the screw rod, the worm wheel is meshed with the worm, and one end of the rotating shaft is arranged on the outside of the fixed frame and connected to a handwheel.

[0014] The present invention also provides a method for using a transformer mounting frame, which uses the above-mentioned transformer mounting frame to install a transformer, including the following steps:

[0015] S1: Connect the transformer to the bracket, and then drive the bracket to rise through the lifting mechanism, so that the bracket drives the transformer, the disc wire and the gear reducer to rise at the same time;

[0016] S2: As the bracket rises, the rack drives the disc wire to rotate through the gear reducer. When the disc wire rotates, it drives several claw blocks to gather inward. Under the action of the claw blocks, the claw blocks clamp the electric pole, and the bracket remains relatively fixed, thereby realizing the installation of the transformer;

[0017] When disassembling the transformer, the following steps are included:

[0018] S11: The bracket is driven down through the lifting mechanism, and the bracket drives the transformer, the disc wire and the gear reducer to descend at the same time;

[0019] S12: The rack drives the disc wire to rotate through the gear reducer. When the disc wire rotates, it drives several claw blocks to move away from the pole, so that the claw blocks release the pole, which is convenient for the disassembly and maintenance of the transformer.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention improves the transformer mounting bracket. When the bracket drives the transformer to rise, the rack can drive the disc wire to rotate through the gear reducer, and the disc wire further drives the claw blocks to gather inward. A plurality of claw blocks cooperate with each other to achieve a clamping effect on the electric pole, and the clamping effect is better. The structure of the three-claw chuck formed by the combination of the disc wire and the claw blocks can provide a larger clamping force and a good clamping effect, so that the bracket can be locked to prevent the bracket from shaking, etc. The operation is convenient, thereby facilitating the installation and disassembly of the transformer, solving the possible dangerous problems of workers working at high altitudes, and improving the overall safety.

[0024] 2. The worm gear and worm gear cooperate with each other in the present invention, and the worm gear and worm gear can provide greater rotational force, thereby facilitating the rotation of the lead screw. The worm gear and worm gear can also prevent reverse rotation, realize self-locking of the lead screw, and prevent the lead screw from reversing under the action of the transformer's gravity. It is more labor-saving, thereby effectively improving the convenience of operation and having extremely high promotion value.

[0025] 3. The gear reducer provided in the present invention can adjust the rotation speed of the disc wire, so that the clamping action of the claw block on the electric pole can be realized only when the transformer rises to a suitable height, thereby realizing the locking work of the transformer at a specified height, facilitating the subsequent installation and disassembly of the transformer.

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] like Figure 1-4 As shown, this embodiment proposes a transformer mounting frame, including a foundation 1, the foundation 1 is fixedly connected to a vertically arranged electric pole 2, two electric poles 2 may be provided, and a bracket 5 is slidably arranged between the electric poles 2. The bracket 5 is connected to a lifting mechanism, the lifting mechanism can drive the bracket 5 to move in the vertical direction, and the bracket 5 is detachably connected to a transformer 9.

[0035] A rack 7 is provided on one side of the electric pole 2, and a disc wire 14 is sleeved on the electric pole 2, and the disc wire 14 is rotatably connected to the bracket 5; a plurality of claw blocks 15 are provided on the upper end surface of the disc wire 14, and a gear ring is provided on the lower end surface of the disc wire 14, and the rack 7 is meshed with the gear ring through a gear reducer, and the gear reducer is connected to the bracket 5.

[0036] The disc wire 14 and the claw block 15 form a structure similar to a "three-claw chuck". Therefore, when the disc wire 14 rotates, the claw block 15 can be driven to move toward the center of the disc wire 14. Under the action of the disc wire 14's own structure, the disc wire 14 has a self-locking function to prevent the claw block 15 from falling off after clamping the electric pole 2.

[0037] The claw block 15 and the rack 7 are staggered. The bracket 5 can only move in the vertical direction, but not rotate. The rack 7 is arranged on one side of the claw block 15. Therefore, when the claw block 15 clamps, the claw block 15 can directly clamp the pole 2 without clamping the rack 7.

[0038] A plurality of claw blocks 15 are annularly sleeved on the outside of the electric pole 2. In the initial state, there is a gap between the claw blocks 15 and the electric pole 2. Therefore, when the bracket 5 moves upward, the rack 7 can drive the disc wire 14 to rotate slowly through the gear reducer, so that the claw blocks 15 can clamp the electric pole 2.

[0039] The gear reducer includes a third gear 19, the bracket 5 is fixedly connected to a fixed block 18, the third gear 19 is rotatably connected to the fixed block 18 via a first rotating shaft, the first rotating shaft is fixedly sleeved with a second gear 17, and the third gear 19 is meshed with the rack 7. Therefore, when the bracket 5 moves, the rack 7 can drive the third gear 19 and the second gear 17 to rotate.

[0040] The fixing block 18 is also rotatably connected to the first gear 4 , the first gear 4 is coaxially connected to the bevel gear 16 , the bevel gear 16 is meshed with the ring gear, and the first gear 4 is meshed with the second gear 17 .

[0041] The diameter of the first gear 4 is larger than that of the second gear 17. The diameter of the second gear 17 is smaller than that of the third gear 19. By adjusting the diameters of the first gear 4, the second gear 17 and the third gear 19, the reduction ratio of the gear reducer can be reasonably adjusted, so that only when the bracket 5 rises to a suitable height, the claw block 15 can complete the clamping effect, which facilitates the locking work of the height of the bracket 5.

[0042] The lifting mechanism includes a plurality of screw rods 8, a fixing frame 20 is fixedly connected between the electric poles 2, the screw rods 8 are rotatably connected to the fixing frame 20, a nut 6 is provided on the screw rods 8, and the nut 6 is fixedly connected to the bracket 5. When the screw rods 8 rotate, the nut 6 can be driven to rotate, thereby driving the bracket 5 to move in the vertical direction.

[0043] The fixing frame 20 is also connected to a limit rod arranged in the vertical direction, and the nut 6 is slidably connected to the limit rod. The limit rod limits the movement of the nut 6 to prevent the nut 6 from rotating when the screw rod 8 rotates, so that when the screw rod 8 rotates, the nut 6 can move vertically.

[0044] The fixed frame 20 is rotatably connected to a rotating shaft 12 arranged in a horizontal direction, the rotating shaft 12 is connected to a worm 11, a worm wheel 10 is fixedly sleeved on the screw 8, the worm wheel 10 is meshed with the worm 11, and one end of the rotating shaft 12 is arranged outside the fixed frame 20 and is connected to a handwheel. Under the action of the worm 11, the worm wheel 10 can be self-locked, thereby preventing the screw 8 from reversing. The worm wheel 10 and the worm 11 cooperate with each other, which can facilitate the rotation of the screw 8, so that the screw 8 can be driven to rotate through the worm gear mechanism, preventing the screw 8 from being unable to rotate due to the excessive weight of the transformer 9.

[0045] The handwheel is connected to a locking mechanism, which can be achieved by opening a limiting hole on the handwheel. The fixing frame 20 is also provided with a positioning hole that matches the limiting hole. A positioning rod can be passed through the limiting hole and the positioning hole. When in use, the positioning rod can be pulled out, and the handwheel can be rotated freely. When the handwheel needs to be locked, the positioning rod can be passed through the limiting block and the positioning hole to achieve the locking of the handwheel.

[0046] A method for using a transformer mounting frame is characterized in that the above-mentioned transformer mounting frame is used to install the transformer, and the following steps are included:

[0047] S1: Connect the transformer 9 to the bracket 5, and then drive the bracket 5 to rise through the lifting mechanism, so that the bracket 5 drives the transformer 9, the disc wire 14 and the gear reducer to rise at the same time;

[0048] S2: As the bracket 5 rises, the rack 7 drives the disc wire 14 to rotate through the gear reducer. When the disc wire 14 rotates, it drives a plurality of claw blocks 15 to gather inward. Under the action of the claw blocks 15, the claw blocks 15 clamp the electric pole 2, and the bracket 5 remains relatively fixed, thereby realizing the installation of the transformer 9;

[0049] When disassembling the transformer, the following steps are included:

[0050] S11: The bracket 5 is driven down by the lifting mechanism, and the bracket 5 drives the transformer 9, the disc wire 14 and the gear reducer to descend at the same time;

[0051] S12: The rack drives the disc wire 14 to rotate through the gear reducer. When the disc wire 14 rotates, it drives a plurality of claw blocks 15 to move away from the pole 2, so that the claw blocks 15 release the pole 2, which facilitates the disassembly and maintenance of the transformer 9.

[0052] The method of the lifting mechanism driving the bracket 5 to move includes: driving the rotating shaft 12 to rotate through the handle, driving the worm wheel 10 to rotate through the worm 11, and then driving the screw rod 8 to rotate, and driving the bracket 5 to move in the vertical direction through the nut 6.

[0053] The moving method of the gear reducer includes: the bracket 5 drives the third gear 19 to move in the vertical direction, and under the action of the rack 7, drives the third gear 19 and the second gear 17 to rotate, the second gear 17 drives the bevel gear 16 to rotate through the first gear 4, and the bevel gear 16 drives the disc wire 14 to rotate.

[0054] It should be noted that the present application improves the transformer mounting bracket. When the bracket 5 drives the transformer 9 to rise, the rack 7 can drive the disc wire 14 to rotate through the gear reducer, and the disc wire 14 then drives the claw block 15 to gather inward. Several claw blocks 15 cooperate with each other to achieve the clamping effect on the electric pole 2, and the clamping effect is better. The structure of the three-jaw chuck formed by the combination of the disc wire 14 and the claw block 15 can provide a larger clamping force and a good clamping effect, so that the bracket 5 can be locked to prevent the bracket 5 from shaking, etc. The operation is convenient, thereby facilitating the installation and disassembly of the transformer, solving the possible dangerous problems of the staff working at high altitudes, and improving the overall safety.

[0055] In addition, the worm gear and worm gear cooperate with each other in the structure, and the worm gear and worm gear can provide greater rotational force, thereby facilitating the driving of the rotation of the lead screw 8, and the worm gear and worm gear can also prevent reverse rotation, realize self-locking of the lead screw 8, and prevent the lead screw from reversing under the action of the gravity of the transformer, and save more effort, thereby effectively improving the convenience of operation, and has extremely high promotion value.

[0056] The screw rod 8 is used for the lifting and lowering of the bracket 5. Therefore, under the action of the gravity of the transformer 9, the transformer 9 will drive the screw rod 8 to rotate in the opposite direction through the nut 6. If only the self-locking function of the worm gear is relied upon, it is easy for the bracket 5 to drop under the action of the gravity of the transformer 9 due to the excessive weight of the transformer 9, the structure being stuck, or the structure being worn too seriously.

[0057] In addition, the gear reducer can adjust the rotation speed of the disc wire 14, so that the clamping effect of the claw block 15 on the electric pole 2 can be realized only when the transformer 9 rises to a suitable height, so that the locking work of the transformer 9 at a specified height can be realized, which is convenient for the subsequent installation and removal of the transformer 9. The purely mechanical structure adopted in this application can effectively reduce the overall construction cost and construction difficulty of the bracket.

[0058] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
