Description

Technical Field

[0001] The invention belongs to the technical field of terminal tools, and in particular relates to a terminal installation structure for a column-mounted transformer. Background Art

[0002] Existing terminal posts are special insulating controls, also known as insulators. For safety reasons, outdoor pole-mounted transformers generally have multiple terminal posts installed on the transformer housing. The main function of the terminal posts is to stabilize and improve the insulation performance. The insulation method of the terminal posts installed on the pole-mounted transformer is generally radial insulation. Currently, in some outdoor environments with strong winds and sand, for safety reasons, the terminal posts of the pole-mounted transformer need to be replaced regularly. It is known that some existing terminal posts (insulators) installed on the pole-mounted transformer include a radial insulator, a conductive core disposed within the radial insulator, and a mounting plate with positioning holes disposed at the bottom of the radial insulator. Therefore, when replacing the terminal posts, workers need tools to remove or tighten multiple bolts to replace the terminal post with the mounting plate with the pole-mounted transformer housing. At the same time as installing and replacing the mounting plate, the conductive core must also be removed or fixed to the internal terminal of the pole-mounted transformer. The entire installation and replacement process is relatively cumbersome, which to a certain extent increases the workload of workers. Therefore, it is very necessary to provide a terminal post installation structure for pole-mounted transformers that has a simple structure, is easy to install, can be quickly replaced, and improves work efficiency.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings. Example

[0025] like Figure 1-8 As shown, a terminal mounting structure for a column-mounted transformer includes a mounting frame 1 and a conductive frame 8. The mounting frame 1 includes positioning frames 2 symmetrically arranged on both sides, and a positioning mechanism 3 is provided inside the positioning frames 2. An entry hole 4 is provided in the middle of the mounting frame 1, and locking frames 5 are provided on both sides of the entry hole 4 relative to the inner side and lower side of the positioning frames 2. A locking mechanism 6 is provided inside the locking frames 5. A locking through hole 7 that cooperates with the locking mechanism 6 is provided on a side wall of the locking frame 5 near the entry hole 4, which can cooperate with the entry hole 4 to achieve locking and unlocking; the conductive frame 8 is arranged at the bottom of the mounting frame 1 and an adjustable conductive docking mechanism 9 is provided inside the conductive frame 8, and a conductive mechanism 10 is provided above the adjustable conductive docking mechanism 9 corresponding to the entry hole 4, and the conductive mechanism 10 is electrically connected to the terminal in the transformer.

[0026] The positioning mechanism 3 includes a driving wheel 31 , one side of the driving wheel 31 is connected to a wide tooth roller 32 , one end of the wide tooth roller 32 is provided with a state switching control mechanism 33 , and the state switching control mechanism 33 is connected to a bearing seat 34 .

[0027] A first gear 35 is provided below the wide tooth roller 32, and a second gear 39 is provided below the state switching control mechanism 33. A long rod is provided inside the first gear 35, and the long rod includes a light rod 36 connected to the first gear 35 and a screw 38 passing through the second gear 39. A sleeve seat 37 is provided at the free end of the light rod 36, and the screw 38 is connected to the second gear 39 through a screw seat 301. A positioning slider 303 is provided at the free end of the screw 38, and the positioning slider 303 is slidably set inside the slide seat 302.

[0028] The state switching control mechanism 33 includes a movable plate 331, a control handle 332 is provided on the top of the movable plate 331, and a central gear 333 connected to the bearing seat 34 is provided in front of the movable plate 331. The first pinion 334 and the second pinion 335 are respectively meshed and connected on both sides of the central gear 333, and the third pinion 336 is meshed and connected below the second pinion 335. The first pinion 334 and the third pinion 336 can be respectively engaged with or disengaged from the second gear 39 when the movable plate 331 rotates.

[0029] The first gear is driven by the second gear and the second gear is engaged with the first gear, and the second gear is engaged with the second gear by the second gear. The toothed roller drives the center gear to rotate, and the center gear drives the second gear to rotate through the first pinion. The second gear rotates in the opposite direction to the first gear, so both drive the screw to move in the direction of the first gear, thereby accelerating the movement to the left. Similarly, when the movable plate is driven to swing to the left by the control handle, the third pinion engages with the second gear, and the wide toothed roller drives the center gear to rotate, and the center gear drives the third pinion to rotate through the second pinion. The third pinion drives the second gear to rotate in the same direction as the first gear. Since the speed of the second gear is faster than that of the first gear, the screw will move slowly to the right. Through the above three operations, the three moving states of the positioning slider are realized, that is, the positioning mechanism can realize the three moving states of the positioning slider through the state switching control mechanism: slow movement to the left, fast movement to the left and reset movement to the right.

[0030] The locking mechanism 6 includes a base plate 61 , a driving motor 62 is provided at the bottom of the base plate 61 , a housing 63 with an upper opening is provided above the base plate 61 , a locking rod 64 is slidably provided inside the housing 63 , and a spring 65 is provided below the locking rod 64 .

A set of spiral slideways 68 are provided on the periphery of the top cover 66 , and a set of pins 69 are symmetrically provided below the inner wall of the locking rod 64 .

[0032] In this embodiment, the working principle of the locking mechanism is as follows: the driving motor drives the top cover to rotate through the driving shaft, and the top cover drives a group of spiral slides on the periphery to rotate. A pair of symmetrically installed pins are provided inside the locking rod. When the spiral slides rotate, they press the pins and move slowly downward (that is, drive the pins to move toward the inside of the shell). Since a spring is provided under the locking rod, the downward pressing process at this time is a process of gradually accumulating force. When the spring is compressed to the bottom, the spiral slide rotates to the gap part. At this time, the spiral slide does not contact the pin. Since the pin has no obstruction and is under the action of the spring, it will press the locking rod. When the locking lever is in a locked position, the cam is released, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the cam is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged, and the latch is engaged

[0033] The present invention is a terminal mounting structure for a pole-mounted transformer. In use, the terminal can be quickly mounted on the body shell of the pole-mounted transformer by cooperating with the provided mounting bracket 1 and the conductive bracket 8. The terminal only needs to be placed into a part of the inner portion of the conductive bracket 8 through the inlet hole 4. The positioning mechanism 3 positions and locks the terminal above the inlet hole 4. The locking mechanism 6 cooperates with the locking through hole 7 to effectively lock the terminal part inside the inlet hole 4, thereby achieving effective and stable installation of the entire terminal. The terminal can be quickly mounted on the body shell of the pole-mounted transformer without the need for fixing bolts. Similarly, when disassembly is required, the lock The disassembly process can be realized by unlocking the fixing mechanism 6 and the positioning mechanism 3. The operation is simple and convenient, and the terminal can be quickly replaced, reducing the work intensity of the staff. Then, the conductive mechanism 10 is driven to rotate and rise through the adjustable conductive docking mechanism 9, so that the spiral conductive seat 102 and the conductive core of the terminal are threadedly plugged and installed, thereby realizing the electrical connection between the conductive core of the terminal and the terminal inside the transformer on the column, realizing synchronous installation with the terminal, saving time and labor, improving installation efficiency, and facilitating disassembly, further reducing the work intensity of the staff. The present invention has the advantages of simple structure, easy installation, rapid replacement and improved work efficiency. Example

[0036] A first pulley 97 is provided on the outside of the shaft seat 93, and a second pulley 98 is provided on the right side of the first pulley 97. The first pulley 97 and the second pulley 98 are connected by a transmission belt 99, and the second pulley 98 is connected to the power of the motor 901 provided on the side of the bracket 91.
