Description

Technical Field

[0001] This utility model relates to the field of transformer equipment technology, and in particular to a dry-type transformer winding fixing bracket. Background Technology

[0002] Dry-type transformers are widely used in high-rise buildings, hospitals, data centers, and subways—places with stringent safety and reliability requirements—due to their superior characteristics such as fire resistance, moisture resistance, and maintenance-free operation. During operation, the windings, as the core component, bear the crucial function of electromagnetic conversion; their structural stability directly affects the transformer's performance and lifespan. While existing dry-type transformers generally meet daily usage needs, some shortcomings still require improvement.

[0003] After the dry-type transformers widely used in the market are assembled, they need to be hoisted into the casing using hoisting equipment. However, after the dry-type transformer is hoisted into the casing, there are often deviations in the installation position. Moreover, due to the large overall weight of the dry-type transformer, it is usually difficult to adjust its position on the ground manually. Therefore, hoisting equipment needs to lift and lower it multiple times to ensure that the dry-type transformer is installed in the correct position inside the casing. During the entire hoisting process, manual assistance is also required for positioning. If a hook falls off during multiple hoistings, the dry-type transformer is prone to falling, which may not only damage the equipment but also pose a certain safety hazard. To address this issue, we propose a dry-type transformer winding fixing bracket to solve the above problems. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a dry transformer winding fixing bracket to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A dry-type transformer winding fixing bracket includes a dry-type transformer body, a winding fixing bracket installed at the top of the dry-type transformer body, and two sets of mounting base plates disposed at the bottom of the winding fixing bracket. Positioning holes are provided on both sides of each of the two sets of mounting base plates. A slide rail seat is installed at the bottom of each mounting base plate, and a slide plate is slidably connected within the slide rail seat. A storage sleeve is installed in the middle of the slide plate, and a guide post is disposed within the storage sleeve. A top plate is installed at the top of the guide post. Mounting grooves are provided at both ends of the front end of each slide plate, and small hydraulic oil pumps are installed within each mounting groove. The output ends of the small hydraulic oil pumps are mounted to the bottom of the top plate via mounting plates. Quick-release components are provided at both the front and rear ends of the top plate.

[0008] As an improved technical solution, the quick-release assembly includes sleeves fixed to the front and rear ends of the guide post and two sets of movable posts disposed inside the sleeves. The two sets of movable posts inside the sleeves are each equipped with a positioning pin at one end opposite to the other via a connecting rod, and a pull handle is installed on the outer wall of the end of the two sets of movable posts away from the mounting base plate. A return spring is provided in the middle of the sleeve.

[0009] As an improved technical solution, the input ends of the two sets of small hydraulic oil pumps on the slide plate are electrically connected to an external controller via wires.

[0010] As an improved technical solution, the surface of the handle on the outside of the movable column is all polished.

[0011] As an improved technical solution, the outer walls of the two sets of movable columns inside the sleeve are fully fitted with the inner wall of the sleeve, and the movable columns and the sleeve form a sliding connection.

[0012] As an improved technical solution, the two ends of the return spring inside the sleeve are respectively connected to the outer walls of the two sets of movable columns, and the two sets of movable columns are elastically connected by the return spring.

[0013] As an improved technical solution, the ends of the positioning pins on the movable column can all be inserted into the positioning holes on the mounting base plate, and the diameter of the positioning pins is the same as the inner diameter of the positioning holes.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] I. This utility model features a laterally movable sliding plate installed at the bottom of the winding fixing bracket, with a small hydraulic pump mounted on the sliding plate. When the main body of the dry-type transformer is hoisted into the housing, the two sets of small hydraulic pumps on the sliding plate can lift the entire main body of the dry-type transformer, allowing the main body of the dry-type transformer to drive the sliding plate to quickly adjust its lateral position along the slide rail seat. This eliminates the need for multiple hoisting operations, effectively improving the installation efficiency of the device and allowing the main body of the dry-type transformer to be adjusted on the ground, avoiding the risk of the main body of the dry-type transformer falling and reducing safety hazards.

[0016] II. This utility model has quick-release components installed at both the front and rear ends of the top plate, which allows the positioning pins on the movable columns to be quickly inserted into the positioning holes on the mounting base plate under the action of elasticity, forming a connection between the top plate and the mounting base plate. After the dry-type transformer body is installed, the pull handle on the outside of the movable column can be pushed to allow the two sets of movable columns to move the positioning pins laterally and quickly disengage them from the positioning holes on the mounting base plate, thus facilitating the device to be used repeatedly.

[0029] Figures 1 to 6As shown, this embodiment provides a dry-type transformer winding fixing bracket, including a dry-type transformer body 1, a winding fixing bracket 2 installed at the top of the dry-type transformer body 1, and two sets of mounting base plates 3 set at the bottom of the winding fixing bracket 2. Positioning holes 4 are opened on both sides of the two sets of mounting base plates 3. A slide rail seat 5 is installed at the bottom of the mounting base plate 3. A slide plate 6 is slidably connected in the slide rail seat 5. A storage sleeve 7 is installed in the middle of the slide plate 6. A guide post 8 is set in the storage sleeve 7. A top plate 9 is installed at the top of the guide post 8. Mounting grooves 10 are opened at both ends of the front end of the slide plate 6. A small hydraulic oil pump 11 is installed in each mounting groove 10. The output end of the small hydraulic oil pump 11 is installed at the bottom of the top plate 9 through the mounting plate 12. Quick release components are set at both the front and rear ends of the top plate 9.

[0030] By installing a laterally movable sliding plate 6 at the bottom of the winding fixing bracket 2, and installing a small hydraulic oil pump 11 on the sliding plate 6, when the dry-type transformer body 1 is hoisted into the housing, the two sets of small hydraulic oil pumps 11 on the sliding plate 6 can lift the dry-type transformer body 1 as a whole, and allow the dry-type transformer body 1 to drive the sliding plate 6 to quickly adjust its lateral position along the slide rail seat 5. This eliminates the need for multiple hoisting operations, effectively improving the installation efficiency of the device, and also allows the dry-type transformer body 1 to be adjusted on the ground, avoiding the risk of the dry-type transformer body 1 falling and reducing safety hazards.

[0031] In other embodiments, the quick-release assembly includes a sleeve 13 fixed to the front and rear ends of the guide post 8 and two sets of movable posts 14 disposed inside the sleeve 13. The two sets of movable posts 14 inside the sleeve 13 are each equipped with a positioning pin 16 through a connecting rod 15 at opposite ends. A pull handle 17 is installed on the outer wall of the end of the two sets of movable posts 14 away from the mounting base plate 3. A return spring 18 is provided in the middle of the sleeve 13.

[0032] By installing quick-release components at both ends of the top plate 9, the positioning pins 16 on the movable column 14 can be quickly inserted into the positioning holes 4 on the mounting base plate 3 under the action of elasticity, forming a connection between the top plate 9 and the mounting base plate 3. After the dry-type transformer body 1 is installed, the pull handle 17 on the outside of the movable column 14 can be pushed to allow the two sets of movable columns 14 to drive the positioning pins 16 to move laterally and quickly disengage from the positioning holes 4 on the mounting base plate 3, thus facilitating the device to be used repeatedly.

[0033] In other embodiments, the input terminals of the two sets of small hydraulic pumps 11 on the slide plate 6 are electrically connected to an external controller via wires.

[0034] This design allows an external controller to control the start, stop, and lifting of the small hydraulic pump 11 on the slide plate 6 in real time, ensuring that the small hydraulic pump 11 can be used normally.

[0035] In other embodiments, the surface of the handle 17 on the outside of the movable column 14 is all polished.

[0036] This design effectively increases the friction between the surface of the handle 17 and the hand, making it easier for the hand to quickly push the handle 17 on the outside of the movable column 14.

[0037] like Figure 6 As shown, the outer walls of the two sets of movable columns 14 inside the sleeve 13 are fully fitted with the inner wall of the sleeve 13, and the movable columns 14 and the sleeve 13 form a sliding connection.

[0038] With this design, when the handle 17 on the outside of the movable column 14 is pulled, the movable column 14 can slide smoothly inside the sleeve 13, ensuring that the movable column 14 can drive the positioning pin 16 to smoothly disengage from the positioning hole 4 on the mounting base plate 3.

[0039] like Figure 6 As shown, the two ends of the return spring 18 inside the sleeve 13 are respectively connected to the outer walls of the two sets of movable columns 14, and the two sets of movable columns 14 are elastically connected through the return spring 18.

[0040] This design allows the return spring 18 inside the sleeve 13 to apply opposing elastic forces to the two sets of movable columns 14, enabling the positioning pins 16 on the two sets of movable columns 14 to be quickly inserted into the positioning holes 4 on the mounting base plate 3.

[0041] like Figure 6 As shown, the ends of the positioning pins 16 on the movable column 14 can all be inserted into the positioning holes 4 on the mounting base plate 3, and the diameter of the positioning pins 16 is the same as the inner diameter of the positioning holes 4.

[0042] With this design, when the positioning pin 16 on the movable column 14 is inserted into the positioning hole 4 on the mounting base plate 3, it can effectively prevent the positioning pin 16 from shaking inside the positioning hole 4, so that the positioning pin 16 can form a stable limiting effect on the top plate 9 as a whole.

[0043] This utility model provides a dry-type transformer winding fixing bracket, the specific working principle of which is as follows:

[0044] When the dry-type transformer body 1 needs to be hoisted as a whole, the two sets of handles 17 on the sleeve 13 can be pulled in opposite directions first, causing the two sets of handles 17 to drive the two sets of movable columns 14 to move in opposite directions. This causes the return spring 18 between the two sets of movable columns 14 to be compressed and contracted by the two sets of movable columns 14, and causes the two sets of positioning pins 16 to move in opposite directions under the action of the two sets of movable columns 14. Then, the top plate 9 can be pushed into the mounting base plate 3. When the top plate 9 drives the two sets of positioning pins 16 on the movable columns 14 to move to the positioning holes 4, the two sets of positioning pins 16 can be inserted into the positioning holes 4 on the mounting base plate 3 under the elastic force of the return spring 18, quickly completing the fixation of the top plate 9. Then, the dry-type transformer body 1 can be hoisted, allowing the dry-type transformer body 1 and the top plate 9 to enter the housing as a whole. When the dry-type transformer body 1 falls into the housing, when it is necessary to adjust the lateral position of the dry-type transformer body 1, that is... Two sets of small hydraulic pumps 11 on the slide plate 6 lift the top plate 9 upwards, allowing the dry-type transformer body 1 to move upwards under the action of the two top plates 9. This causes the two mounting base plates 3 to detach from the bottom surface of the outer casing. Then, the dry-type transformer body 1 can be pushed laterally, causing the dry-type transformer body 1 to drive the slide plates 6 at the bottom of the two top plates 9 to slide laterally along the slide rail seat 5. Once the dry-type transformer body 1 has moved to the appropriate position, the two sets of small hydraulic pumps 11 on the slide plate 6 can be restarted, causing the two sets of small hydraulic pumps 11 to drive the top plate 9 downwards. This causes the mounting base plates 3 at the bottom of the dry-type transformer body 1 to move to the designated installation position on the outer casing. Then, the two sets of pull handles 17 can be moved again, causing the two sets of movable columns 14 to drive the two sets of positioning pins 16 to leave the positioning holes 4 on the mounting base plates 3. This completes the disassembly of the top plate 9, and the operation is now finished.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
