Description

Technical Field

[0001] This application relates to the technical field of pole-mounted circuit breaker manufacturing, and in particular to an auxiliary device for assembling a pole-mounted circuit breaker frame. Background Technology

[0002] A pole-mounted circuit breaker is a high-voltage electrical device installed on a utility pole, belonging to the category of pipe protection devices in outdoor power distribution systems. It automatically cuts off the current when overloads, short circuits, or other faults occur in the circuit, preventing equipment damage and power grid collapse.

[0003] In existing pole-mounted circuit breakers, the upper and lower parts are typically assembled separately first. Then, the upper main body is lifted and placed on the lower main body for final assembly. Chinese invention patent CN119208094A discloses a pole-mounted circuit breaker with lifting rings on the upper surface and handrails on both sides. Since this main body is the upper part during assembly, the assembly process primarily involves lifting the upper body using the handrails and moving it onto the lower body.

[0004] Regarding the aforementioned technologies, the process of lifting the upper main body during the assembly of pole-mounted circuit breakers is physically demanding, resulting in high workload for assembly personnel. Utility Model Content

[0005] To facilitate the installation of pole-mounted circuit breakers and reduce workload, this application provides an auxiliary device for assembling pole-mounted circuit breaker frames.

[0006] This application provides an auxiliary device for assembling a pole-mounted circuit breaker frame, which adopts the following technical solution:

[0007] An auxiliary device for assembling a pole-mounted circuit breaker frame includes a support frame, a mounting base, a mounting rod, a drive assembly, and a connecting assembly. The mounting base is slidably mounted on the support frame. The mounting rod is mounted on the mounting base and is respectively located at both ends of the mounting base. The drive assembly can drive the mounting base to move up and down. The connecting assembly is mounted on the mounting rod and can lift the upper body of the pole-mounted circuit breaker.

[0008] By adopting the above technical solution, the upper body of the pole-mounted circuit breaker is hoisted using the connecting component, and the mounting base is driven to move up and down on the support frame by the drive component, which in turn drives the mounting rod and the upper body to move up and down, thereby facilitating the assembly of the pole-mounted circuit breaker, avoiding manual lifting of the upper body, and reducing the workload of assembly personnel.

[0009] Optionally, the support frame includes two parallel bottom support rods, a vertical support rod disposed on the top support rod, a top support rod disposed at the upper end of the two vertical support rods, and an oblique support rod disposed between the bottom support rod and the vertical support rod. The vertical support rod is disposed at a rear position of the bottom support rod, the lower end of the oblique support rod is disposed at the front end of the bottom support rod, and the mounting rod extends toward the front end of the support frame.

[0010] By adopting the above technical solution, two parallel bottom support rods provide a stable support foundation for the support frame; the vertical support rod is located at the rear of the bottom support rod and connected through the top support rod, enhancing the structural stability; the diagonal support rod connects the front end of the bottom support rod and the vertical support rod, further reinforcing the overall frame; the mounting rod extends towards the front end of the support frame to facilitate the connection of components for hoisting the upper body of the pole-mounted circuit breaker, and the extension direction of the mounting rod is the same as the setting direction of the diagonal support rod, which can prevent forward tilting during hoisting.

[0011] Optionally, positioning plates are provided at both ends of the mounting base, and sliders are provided on the side of the positioning plates away from the mounting base. Sliding rods are provided on both vertical support rods, and the sliding rods slide through the sliders.

[0012] By adopting the above technical solution, the positioning plate and the cooperation between the slider and the sliding rod can make the mounting seat slide stably up and down on the support frame. This ensures that when the auxiliary device for assembling the pole-mounted circuit breaker frame is running, the mounting seat drives the mounting rod and the upper body of the hoisted pole-mounted circuit breaker to move smoothly, which is beneficial to improving the stability and accuracy of the assembly process.

[0013] Optionally, the mounting rod has an abutment surface that can abut against the side wall of the positioning plate, and at least two fixing bolts are provided on the mounting rod along its length direction. The fixing bolts can pass through the mounting rod and be threaded onto the positioning plate.

[0014] By adopting the above technical solution, the contact surface of the mounting rod abuts against the side wall of the positioning plate, and the positioning plate is connected by a fixing bolt through the mounting rod threadedly, so that the mounting rod can be stably installed on the positioning plate, thereby improving the stability of the auxiliary device structure for assembling the pole-mounted circuit breaker frame.

[0015] Optionally, a connecting rod is provided between the two vertical support rods, and the driving assembly includes a lead screw and a power component. The lead screw is rotatably mounted on the connecting rod, extends vertically upward, and is threaded through the mounting base. The power component is used to drive the lead screw to rotate.

[0016] By adopting the above technical solution, the connecting rod makes the connection between the two vertical support rods more stable; the screw rotation and the screw connection of the mounting seat can convert the rotational motion of the screw into the vertical linear motion of the mounting seat. The screw rotation is driven by the power component to realize the vertical movement of the mounting seat, which can conveniently and accurately control the lifting and lowering of the mounting seat. Then, the upper body of the column circuit breaker can be assembled by hoisting it with the help of the connecting component, reducing the labor intensity of manually lifting the upper body.

[0017] Optionally, the power component includes a motor, a worm gear, and a worm. The worm gear is coaxially mounted on the lead screw, the worm meshes with the worm gear, and the output end of the motor is connected to the worm.

[0018] By adopting the above technical solution, a motor, worm gear, and worm are used as power components. The output end of the motor is connected to the worm gear, which drives the worm gear to rotate, thereby driving the lead screw to rotate and thus driving the mounting base to move up and down. This realizes the lifting and lowering operation of the upper body of the pole-mounted circuit breaker, so that the lifting of the upper body no longer relies on manual operation, reducing the workload of assembly personnel. At the same time, the worm gear transmission has a self-locking function, which can ensure the stability of the mounting base on the lead screw, which is conducive to the accurate installation of the upper body of the pole-mounted circuit breaker.

[0019] Optionally, the connecting assembly includes a connecting chain and a connecting hook, the connecting chain being disposed on the mounting rod, the connecting hook being disposed at the lower end of the connecting chain, and the connecting hook being adapted to the lifting ring on the pole-mounted circuit breaker.

[0020] By adopting the above technical solution, and using a connecting chain and a connecting hook adapted to the lifting ring of the pole-mounted circuit breaker, the auxiliary device can be connected to the upper body of the pole-mounted circuit breaker.

[0021] Optionally, the connecting assembly further includes a positioning rod with positioning blocks slidably disposed at both ends of the positioning rod. The positioning rod has grooves at both ends for the two positioning blocks to slide along the length of the positioning rod. Each positioning block is provided with a connecting hook, and the opening directions of the two connecting hooks located on the same positioning rod are opposite. The positioning rod is also provided with an elastic element that drives the two positioning blocks away from each other, and a control element that controls the positioning blocks to slide in the direction of the movement.

[0022] By adopting the above technical solution, the connecting components of the auxiliary device for assembling the pole-mounted circuit breaker frame can achieve stable hoisting of the upper body of the pole-mounted circuit breaker with the help of positioning rods, positioning blocks, connecting hooks, elastic elements and control elements. The connecting hooks with opposite opening directions enhance the connection stability, the elastic elements keep the positioning blocks open to accommodate lifting rings with different spacing, and the control elements facilitate the adjustment of the position of the positioning blocks and make it easy to connect or separate them from the lifting rings, thereby reducing the manpower consumption and labor intensity of workers when assembling the pole-mounted circuit breaker.

[0023] Optionally, the elastic element is a spring, and the positioning rod has a receiving groove for installing the spring at one end of the slide near the other positioning block. The end of the spring abuts against the positioning block and is always in a compressed state.

[0024] By adopting the above technical solution, the spring is always in a compressed state, which allows the spring to push the positioning block to slide in the groove of the positioning rod, so that the two connecting hooks on the same positioning rod are far apart and the lifting ring is locked, thus achieving better adaptation and connection of the lifting ring of the pole-mounted circuit breaker.

[0025] Optionally, the control element is a control rod, which passes through the end face of the positioning rod and is connected to the positioning block.

[0026] By adopting the above technical solution, and using the control method of connecting the control rod through the end face of the positioning rod and the positioning block, the positioning block can be flexibly manipulated to slide along the length of the positioning rod. With the help of the compressed spring, the two positioning blocks can be moved away from or closer to each other, thereby facilitating the adjustment of the position of the connecting hook. This makes it easier for the connecting hook to be matched and connected with the lifting ring on the pole-mounted circuit breaker, so as to realize the hoisting and disassembly of the upper body of the pole-mounted circuit breaker.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. The drive component drives the mounting base to move up and down, which in turn moves the upper body of the pole-mounted circuit breaker, which is hoisted by the connecting component, up and down, avoiding manual lifting and reducing the workload of assembly personnel;

[0029] 2. The pole-mounted circuit breaker is hoisted by setting up positioning rods, connecting hooks, elastic elements, and control elements. The two connecting hooks with opposite opening directions make the hoisting process safer and more stable, while the elastic elements and control elements make the hoisting process convenient and quick.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses an auxiliary device for assembling a pole-mounted circuit breaker frame. (Refer to...) Figure 1 The auxiliary device includes a support frame 1, a mounting base 2, a mounting rod 3, a drive assembly 4, and a connecting assembly 5. The mounting base 2 is slidably mounted on the support frame 1, and the drive assembly 4 can drive the mounting base 2 to move up and down. The mounting rod 3 is mounted on the mounting base 2 and is respectively located at both ends of the mounting base 2. The connecting assembly 5 is mounted on the mounting rod 3 and can lift the upper body of the pole-mounted circuit breaker. This structural combination allows the upper body of the pole-mounted circuit breaker to be lifted by the connecting assembly 5, and then easily moved up and down under the action of the drive assembly 4, which facilitates assembly with the lower body and reduces the labor intensity of manually lifting the upper body.

[0038] Reference Figure 1 and Figure 2 Specifically, the support frame 1 includes two parallel bottom support rods 11, a vertical support rod 12 mounted on the bottom support rods 11, a top support rod 13 mounted on the upper ends of the two vertical support rods 12, and an inclined support rod 14 positioned between the bottom support rods 11 and the vertical support rods 12. The bottom support rods 11, as the main support components, are horizontally mounted on the ground; the vertical support rods 12 are vertically mounted behind the bottom support rods 11; the lower end of the inclined support rod 14 is located at the front end of the bottom support rods 11, and the upper end extends upwards at an angle and is fixed to the side wall of the vertical support rods. The connection points of the vertical support rods 12 and the inclined support rods 14 can be fixed using bolts or other methods. Mounting rod 3 is mounted on vertical support rod 12 and extends towards the front end of bottom support rod 11. The upper main body of the pole-mounted circuit breaker can be fixed to the front end of mounting rod 3. Therefore, the triangular structure design of the inclined support rod 14 enhances the stability of support frame 1, improves the support effect on pole-mounted circuit breaker, and prevents support frame 1 from swaying or tilting to the front during hoisting.

[0039] Reference Figure 1 and Figure 2In this embodiment, the mounting base 2 is parallel to the top support rod 13, and its two ends are slidably mounted on the vertical support rod 12. Positioning plates 21 are fixed to both ends of the mounting base 2. The positioning plates 21 are rectangular and parallel to the side walls of the vertical support rod 12. A slider 22 is fixed to the side of the positioning plate 21 away from the mounting base 2 by bolts or other means. The slider 22 is a rectangular block, and multiple sliders can be arranged along the vertical direction. A sliding rod 121 is fixed to the side walls of the two vertical support rods 12 that are close to each other. The sliding rod 121 is typically a cylindrical rod. The sliding rod 121 slides through the slider 22, allowing the mounting base 2 to slide up and down along the vertical support rod 12. To prevent the slider 22 of the mounting base 2 from sliding down the sliding rod 121, a limiting block is fixed to the lower end of the sliding rod 121. The limiting block is fixed to the corresponding vertical support rod 12 by bolts or buckles.

[0040] Reference Figure 1 and Figure 2 In this embodiment, the rear end of the mounting rod 3 is fixed to the positioning plate 21. The mounting rod 3 can be configured as a round rod, and its rear end, i.e., the side wall near the positioning plate 21, has an abutment surface 31 (see reference). Figure 4 The abutment surface 31 can abut against the side wall of the positioning plate 21. The abutment between the mounting rod 3 and the positioning plate 21 can make the mounting rod 3 more stably installed on the mounting base 2. At least two fixing bolts are provided on the mounting rod 3 along its own length direction. The fixing bolts can pass through the mounting rod 3 and be threaded to the positioning plate 21, thereby realizing the detachable connection of the mounting rod 3.

[0041] Reference Figure 1 and Figure 2 In this embodiment, a connecting rod 15 is fixedly arranged between the two vertical support rods 12. The connecting rod 15 is parallel to the top support rod 13 and is located below the mounting base 2. The drive assembly 4 includes a lead screw 41 and a power component 42. The lower end of the lead screw 41 is rotatably mounted on the connecting rod 15 via a bearing or other means. The upper end of the lead screw 41 extends vertically upward and is threaded through the mounting base 2. The upper end of the lead screw 41 can be suspended in the air. Preferably, to improve the stability of the lead screw 41, a support can be fixed to the lower surface of the top support rod 13, and the upper end of the lead screw 41 can be rotatably connected to the support. The power component 42 is arranged on the connecting rod 15 and is used to drive the lead screw 41 to rotate. When the lead screw 41 rotates, under the drive of the lead screw 41 and the limiting of the slide rod 121, the mounting base 2 can slide up and down along the slide rod 121, thereby driving the mounting rod 3 to move up and down, that is, controlling the pole-mounted circuit breaker connected to the mounting rod 3 to move up and down.

[0042] Reference Figure 2 and Figure 3In this embodiment, the power component 42 includes a motor 421, a worm gear 422, and a worm 423. The worm gear 422 is coaxially mounted on the lead screw 41, and the worm 423 meshes with the worm gear 422. The output end of the motor 421 is connected to the worm 423. The motor 421 can be a servo motor 421, which has precise speed and torque control capabilities. When the motor 421 starts, it drives the worm 423 to rotate, which in turn drives the worm gear 422 to rotate, thereby causing the lead screw 41 to rotate. This worm gear 422-worm 423 transmission has a self-locking function; when the motor 421 stops, the lead screw 41 will not rotate on its own, ensuring the stability of the mounting base 2.

[0043] Preferably, in order to facilitate the installation of the power component 42, a housing can be provided on the connecting rod 15, and both the worm gear 422 and the worm 423 are encapsulated in the housing. The housing is provided with an oil injection hole to facilitate the installation of a lubrication system to lubricate the worm gear 422 and the worm 423.

[0044] Reference Figure 1 and Figure 4 In this embodiment, the connecting component 5 includes a connecting chain 51 and a connecting hook 52. The connecting chain 51 is generally made of a high-strength chain with high tensile strength. The connecting chain 51 is mounted on the mounting rod 3, and the connecting hook 52 is located at the lower end of the connecting chain 51. The connecting hook 52 is adapted to the lifting ring on the pole-mounted circuit breaker. By hooking the connecting hook 52 onto the lifting ring on the pole-mounted circuit breaker, the upper body of the pole-mounted circuit breaker can be hoisted.

[0045] Furthermore, the connecting component 5 may also include a positioning rod 53, with positioning blocks 531 slidably disposed at both ends of the positioning rod 53. Slide grooves are formed at both ends of the positioning rod 53, allowing the two positioning blocks 531 to slide along the length of the positioning rod 53. The slide grooves are located on the lower surface of the positioning rod 53. The positioning blocks 531 may be T-shaped or dovetail-shaped, allowing them to slide stably within the slide grooves. Connecting hooks 52 are fixed to the lower surface of the positioning blocks 531, and the opening directions of the two connecting hooks 52 located on the same positioning rod 53 are opposite. This facilitates the attachment of lifting rings at different positions on the pole-mounted circuit breaker, while preventing the connecting hooks 52 from easily detaching from the lifting rings. In other embodiments, to prevent detachment, a safety hook or safety catch (not shown in the figure) may be provided on the connecting hook 52.

[0046] Reference Figure 4 and Figure 5Furthermore, the positioning rod 53 is also equipped with an elastic element 54 that drives the two positioning blocks 531 away from each other, and a control element 55 that controls the positioning blocks 531 to slide towards each other. Specifically, the elastic element 54 is a spring, and the positioning rod 53 has a receiving groove at one end of the slide near the other positioning block 531 on the positioning rod 53. The spring is installed in the receiving groove, and the end of the spring abuts against the side wall of the positioning block 531. The spring is always in a compressed state. When the control element 55 does not apply force, the spring will push the positioning blocks 531 away from each other, so that the connecting hook 52 can better hook the lifting ring. The control element 55 is a control rod that slides through the end face of the positioning rod 53 and connects to the positioning block 531. The control rod can be set as a round rod, and a pressing block can be fixedly set at its end. By pressing the control rod, the positioning block 531 can overcome the elastic force of the spring and slide towards the center, making it easy to remove or hang the upper body of the pole-mounted circuit breaker.

[0047] When suspending a circuit breaker on a pole, first hook the connecting hook 52, which is furthest from the worker and closer to the rear end, onto the lifting ring. Then push the positioning rod 53 towards the rear end, causing the positioning block 531 at the rear end to slide relative to the front end. Next, press the control rod at the front end to control the positioning block 531 at the front end to slide relative to the rear end, bringing the two connecting hooks 52 as close as possible. At this point, align the connecting hook 52 at the front end with the lifting ring of the circuit breaker on the pole, release the control rod, and the connecting hook 52 at the front end will hook into the lifting ring.

[0048] The implementation principle of the auxiliary device for assembling a pole-mounted circuit breaker frame according to an embodiment of this application is as follows: When assembling the pole-mounted circuit breaker, the auxiliary device is first placed in a suitable position, and the lifting ring of the upper body of the pole-mounted circuit breaker is hooked by the connecting hook 52 of the connecting component 5; then the power component 42 is activated, the motor 421 drives the worm gear 423 to rotate, the worm gear 423 drives the worm wheel 422 to rotate, which in turn causes the lead screw 41 to rotate. The rotation of the lead screw 41 drives the mounting base 2 to slide upward along the vertical support rod 12, thereby lifting the upper body of the pole-mounted circuit breaker; after the lower body is moved to a suitable position below the upper body, the power component 42 is reversed to lower the mounting base 2, completing the assembly of the upper and lower bodies. This structural design avoids manual lifting of the upper body, greatly reducing the labor intensity of workers, improving work efficiency, and also reducing the safety hazards that may be caused by manual lifting.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
