Description

Technical Field

[0001] This utility model relates to the field of power equipment assembly tools, specifically to a mobile vehicle for supporting the insulating support column of a circuit breaker on a positioning post. Background Technology

[0002] The 10kV outdoor vacuum pole-mounted circuit breaker is a primary device used in high-voltage power systems. Currently, during the production process, the circuit breaker housing and insulating support need to be manually lifted and positioned phase by phase. After positioning, bolts are used for tightening. Assembling one circuit breaker requires lifting and positioning three times. Because the mounting holes are inside the stainless steel housing, it is not convenient to see them. Moreover, the angle of lifting the insulating support is inconsistent each time, and it is not possible to make the copper rod of the insulating support perpendicular to the stainless steel housing in one go. As a result, two employees need to work together to determine whether the hole positions are aligned before bolts can be used for fixing. Relying on manual lifting and positioning is time-consuming and labor-intensive, and also causes a certain degree of human resource waste, which greatly reduces the efficiency of production and assembly.

[0029] Example

[0030] Please refer to Figures 1-3 This embodiment provides a mobile vehicle for lifting and positioning circuit breaker insulation supports on a positioning post, including: a mobile vehicle body 1; a lifting and positioning mechanism, the lifting and positioning mechanism including a base 2 and a lifting assembly for lifting the insulation support, the lifting assembly being lifted and lowered on the base 2, wherein the lifting assembly includes a lifting plate 3 and a plurality of positioning components disposed on the lifting plate 3, the base 2 being a shell structure, the lifting plate 3 being slidably disposed within the base 2, and the plurality of positioning components being evenly spaced on the lifting plate 3, with the positioning components extending out of the base 2.

[0031] In this embodiment, the mobile vehicle body 1 is used to transport the lifting and positioning mechanism and the pole-mounted circuit breaker insulation support placed on the lifting and positioning mechanism laterally, so that it reaches the pre-installation position of the circuit breaker housing.

[0032] In this embodiment, the aforementioned lifting and positioning mechanism is used to longitudinally lift the pole-mounted circuit breaker insulation support, bringing it to the pre-installation position, and then fixing it to the circuit breaker housing with bolts. Specifically, the aforementioned base 2 is used to install and guide the lifting assembly, which is used to lift and position the pole-mounted circuit breaker insulation support to be installed.

[0033] It should be noted that the number of the aforementioned positioning components is three, consistent with the number of pole-mounted circuit breaker insulation supports installed in a single operation. The base 2 has through holes for limiting the longitudinal transport of the lifting assembly, ensuring that the lifting assembly remains perpendicular to the ground during longitudinal movement to prevent tilting. The lifting plate 3 is used to lift the positioning components, thereby delivering the pole-mounted circuit breaker insulation supports placed on the positioning components to the circuit breaker housing installation position, facilitating subsequent locking and fixing.

[0034] Please refer to Figure 2 and Figure 3 In some embodiments of this example, any of the above positioning components includes a positioning cylinder 4 and a lifting spring 5. One end of the lifting spring 5 is connected to the lifting plate 3, and the other end of the lifting spring 5 is connected to the positioning cylinder 4.

[0035] In this embodiment, the positioning cylinder 4 is used to position a single pole-mounted circuit breaker insulation support. The positioning cylinder 4 has a groove structure, and the lifting spring 5 is installed at the bottom of the positioning cylinder 4 to support the positioning cylinder 4. When the pole-mounted circuit breaker insulation support that is lifted and positioned reaches the pre-installation position, the lifting plate 3 continues to move longitudinally, so that the lifting spring 5 is compressed, which makes it easier to press the pole-mounted circuit breaker insulation support to be installed against the circuit breaker housing, so that it can be locked and fixed by bolts later.

[0036] Please refer to Figures 1-3 In some embodiments of this example, the positioning cylinder 4 is provided with an opening 6 for positioning the copper column on the side wall of the insulating support.

[0037] In this embodiment, the opening 6 is used to accommodate the copper column of the side wall of the pole-mounted circuit breaker insulation support, thereby positioning the orientation of the pole-mounted circuit breaker insulation support.

[0038] Please refer to Figure 2 and Figure 3 In some embodiments of this example, a limit switch 7 is provided between the positioning cylinder 4 and the lifting plate 3.

[0039] In this embodiment, the limit switch 7 is used to detect whether the pole-mounted circuit breaker insulation support has reached the predetermined installation position. When the pole-mounted circuit breaker insulation support reaches the predetermined position, it rises again, the lifting spring 5 is compressed, and the limit switches 7 at the bottom of the positioning cylinder 4 and the support of the lifting plate 3 are triggered, thereby controlling the lifting to stop automatically. This is used to protect the pole-mounted circuit breaker insulation support from damage and improve the safety of the operation.

[0040] Please refer to Figure 2 In some embodiments of this example, a lifting element 8 for driving the lifting plate 3 to move is provided between the bottom of the lifting plate 3 and the base 2.

[0041] In this embodiment, the lifting element 8 is used to control the lifting plate 3 to slide up and down inside the base 2, thereby driving the pole-mounted circuit breaker insulation support to move longitudinally.

[0042] Preferably, the lifting element 8 is a scissor lift. The lifting drive of the scissor lift achieves the lifting function through the extension and folding of the scissor structure. The scissor lift can quickly reach the required height, greatly shortening the preparation time for operation.

[0043] Please refer to Figure 2 In some embodiments of this example, the base 2 is provided with a drive motor 9 for driving the lifting element 8, and the output end of the drive motor 9 is connected to the lifting element 8.

[0044] In this embodiment, the drive motor 9 is the core power source of the scissor lift. Through the operation of the drive motor 9, the moving parts of the scissor structure are extended and retracted. This mechanical movement enables the lifting platform to achieve smooth vertical lifting. Specifically, by reversing direction and adjusting the speed, the drive motor 9 can precisely control the height and speed of the lifting platform, achieving precise high-altitude operation positioning.

[0045] Please refer to Figure 2 In some embodiments of this example, the base 2 is provided with a power supply 10 for powering the drive motor 9.

[0046] In this embodiment, the power supply 10 is used to provide stable power. The power supply 10 can provide stable and reliable current and voltage to ensure that the electronic equipment can work independently.

[0047] Preferably, the power supply 10 uses a lithium-ion battery. Lithium-ion batteries have high energy density and high average output voltage. They have low self-discharge; good batteries discharge less than 2% per month. They have no memory effect. They have a wide operating temperature range of -20℃ to 60℃. They have excellent cycle performance, can be charged and discharged quickly, have a charging efficiency of up to 100%, and have high output power. They also have a long service life.

[0048] Please refer to Figure 1 In some embodiments of this example, the outer wall of the base 2 is provided with a drive button 11 for controlling the start and stop of the drive motor 9, and the drive button 11 is connected in series between the power supply 10 and the drive motor 9.

[0049] In this embodiment, the drive button 11 is used by the operator to control the movement of the lifting mechanism according to the actual installation requirements, which facilitates manual operation by the user and improves the convenience of the operation.

[0050] Please refer to Figure 1 and Figure 2 In some embodiments of this example, the mobile vehicle body 1 is provided with a drive handle 12.

[0051] In this embodiment, the drive handle 12 is an important control component of the mobile vehicle, allowing the user to easily control its direction and speed. The user can rotate the drive handle 12 to drive the wheels of the mobile vehicle to achieve forward, backward, and turning movements. The design of the drive handle 12 allows the user to control the direction and speed of the mobile vehicle more intuitively, improving the accuracy and flexibility of operation.

[0052] When in use, place the pole-mounted circuit breaker insulation support to be installed into the positioning cylinder 4, so that the copper column on the side wall of the pole-mounted circuit breaker insulation support is located in the opening 6 at the top of the positioning cylinder 4. Hold the drive handle 12 by hand to move the moving vehicle body 1 directly below the pre-installed circuit breaker housing. Press the drive button 11 by hand. When the pole-mounted circuit breaker insulation support reaches the appropriate height, it stops, or when the limit switch 7 at the bottom of the positioning cylinder 4 detects that the height has reached the preset height, it controls the lifting element 8 to stop the operation. Finally, fix the pole-mounted circuit breaker insulation support to the circuit breaker housing with bolts.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
