[0001] This application relates to the field of power equipment technology, and in particular to a handcart-type circuit breaker switching device. Background Technology

[0002] When a 12kV handcart-type circuit breaker chassis in a substation or power plant malfunctions, it must be rotated 90 degrees before being removed for repair. Because the circuit breaker weighs 150 kg and has a relatively smooth surface, there are few points of leverage for lifting it. Furthermore, the circuit breaker's contact arms cannot be pulled forcefully. Therefore, manually rotating the circuit breaker 90 degrees is very difficult. At least four people are needed to lift the 150 kg circuit breaker to the ground for rotation, or a transport vehicle must be used. This is extremely laborious and poses numerous safety hazards, including damaging the circuit breaker, it falling and breaking, and injuring workers.

[0003] Regarding the aforementioned related technologies, the inventors believe that in solving the problem of the 12KV handcart circuit breaker chassis maintenance project, there are issues such as the difficulty in flipping the switch, the risk of the circuit breaker falling and damaging it, and injuring workers.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses a handcart-type circuit breaker tipping device. See also... Figure 1 , Figure 2 The handcart-type circuit breaker tilting device includes a support assembly 1, a lifting assembly 2 located above the support assembly 1, and a tilting assembly 4 located above the lifting assembly 2. The tilting assembly 4 and the lifting assembly 2 are fixedly connected by a connecting assembly 3. The lifting assembly 2 can drive the tilting assembly 4 to lift or lower its height. A connecting piece 5 is fixedly connected to one side of the tilting assembly 4. The tilting assembly 4 can drive the connecting piece 5 to tilt. The circuit breaker is fixedly connected to the side of the connecting piece 5 opposite to the tilting assembly 4, thereby causing the tilting assembly 4 to drive the circuit breaker to rotate.

[0026] The support assembly 1 includes a frame 12, which includes a horizontally arranged first vertical beam 123. A second vertical beam 124 is arranged parallel to one side of the first vertical beam 123. Four casters 11 are fixedly connected to the bottom of the four corners of the first vertical beam 123 and the second vertical beam 124 respectively. Pushing the four casters 11 can move the frame 12.

[0027] A first horizontal beam 121 and a second horizontal beam 122 are vertically arranged between the first vertical beam 123 and the second vertical beam 124. The first horizontal beam 121 and the second horizontal beam 122 are arranged in parallel. The ends of the first horizontal beam 121 are fixedly connected to the first vertical beam 123 and the second vertical beam 124, respectively. The ends of the second horizontal beam 122 are fixedly connected to the first vertical beam 123 and the second vertical beam 124, respectively.

[0028] A support frame 13 is fixedly connected to the upper surface of the frame 12. The support frame 13 includes a third vertical beam 131 that is vertically fixedly connected to the upper surface of the first crossbeam 121. A fourth vertical beam 132 is provided on one side of the third vertical beam 131. The fourth vertical beam 132 is parallel to the third vertical beam 131 and is fixedly connected to the upper surface of the second crossbeam 122 and perpendicular to the second crossbeam 122.

[0029] A fifth vertical beam 133 is provided on one side of the third vertical beam 131. The fifth vertical beam 133 is parallel to the third vertical beam 131, and its bottom end is fixedly connected to the upper surface of the first horizontal beam 121. The fifth vertical beam 133 is perpendicular to the upper surface of the first horizontal beam 121. A sixth vertical beam 134 is vertically provided on one side of the fifth vertical beam 133. The sixth vertical beam 134 is fixedly connected to the upper surface of the second horizontal beam 122 and is perpendicular to the second horizontal beam 122.

[0030] A third horizontal beam 135 is fixedly connected to the top of the third vertical beam 131 and the fourth vertical beam 132. The third horizontal beam 135 is fixedly connected to the third vertical beam 131 and the fourth vertical beam 132 respectively.

[0031] A fourth horizontal beam 136 is provided at the top of the fifth vertical beam 133 and the sixth vertical beam 134. The fourth horizontal beam 136 is parallel to the third horizontal beam 135 and is fixedly connected to the fifth vertical beam 133 and the sixth vertical beam 134 respectively.

[0032] The lifting assembly 2 includes a base plate 25 horizontally arranged on the third crossbeam 135 and the fourth crossbeam 136. The upper surface of the third crossbeam 135 is fixedly connected to the lower surface of the base plate 25, and the upper surface of the fourth crossbeam 136 is fixedly connected to the lower surface of the base plate 25.

[0033] A first worm gear 21 is horizontally mounted on the base plate 25. A lifting handwheel 22 is coaxially fixedly connected to the end of the first worm gear 21. A first worm 23 is threadedly connected to one side of the first worm gear 21. The first worm 23 is perpendicular to the first worm gear 21. A screw 24 is coaxially mounted inside the first worm gear 21 and is threadedly connected to the first worm 23. When the first worm 23 is rotated, the screw 24 moves along the axis of the first worm 23 inside the first worm 23. The screw 24 is threadedly connected to the base plate 25, and the bottom end of the first worm 23 is rotatably connected to the base plate 25.

[0034] The first horizontal beam 121, the second horizontal beam 122, the third horizontal beam 135, the fourth horizontal beam 136, and the third vertical beam 131, the fourth vertical beam 132, the fifth vertical beam 133, and the sixth vertical beam 134 are connected to form an internally hollow lifting space. The screw 24 is located inside the lifting space and can move up and down relative to the ground within it. When the bottom end of the screw 24 is moved to its lowest position, it can contact the upper surface of the first horizontal beam 121, preventing the bottom end of the screw 24 from contacting the ground and damaging it.

[0035] When the lifting handwheel 22 is rotated, the lifting handwheel 22 drives the first worm gear 21 to rotate, the first worm gear 21 synchronously drives the first worm 23 to rotate, and the first worm 23 drives the screw 24 to rotate. Because the screw 24 is threadedly connected to the base plate 25 and the base plate 25 is fixed on the base, the screw 24 can move in the vertical direction, driving the lifting assembly 2 to move vertically up and down. Furthermore, since the first worm gear 21 can self-lock the first worm 23 when it drives it to rotate, the screw 24 can form a self-locking structure when it is raised and lowered in the height direction.

[0036] The connecting component 3 includes a pad 31 that is fixedly connected to the top of the screw 24. The pad 31 is circular. A connecting bracket 32 ​​is rotatably connected above the pad 31. The connecting bracket 32 ​​includes a horizontally arranged connecting base plate 25. The bottom end of the connecting base plate 25 is rotatably connected to the pad 31. A first baffle 321 is vertically arranged on the side of the connecting base plate 25 near the lifting handwheel 22. The top end of the first baffle 321 is fixedly connected to the bottom end of the connecting base plate 25.

[0037] A second baffle 322 is vertically installed on the side of the connecting base plate 25 away from the lifting handwheel 22. The top end of the second baffle 322 is fixedly connected to the bottom end of the connecting base plate 25. The connecting base plate 25 and the first baffle 321 and the second baffle 322 at both ends form a space. When the screw 24 drives the pad 31 to rotate, the pad 31 can rotate within this space without leaving it.

[0038] The lifting assembly 2 includes a support column 41 fixedly connected to the surface of the connecting bracket 32. The support column 41 is cuboid and perpendicular to the connecting bracket 32. A second worm gear 42 is horizontally connected to the upper part of the support column 41. The two ends of the second worm gear 42 pass through the side walls of the support column 41, and the second worm gear 42 and the support column 41 are rotatably connected. A flip handwheel 43 is coaxially fixedly connected to one end of the second worm gear 42. A second worm 44 is threadedly connected above the second worm gear 42. The two ends of the second worm 44 pass through the surface of the support column 41, and the second worm 44 is rotatably connected to the support frame 4113. The second worm gear 42 is perpendicular to the second worm 44.

[0039] The connector 5 includes a connecting plate 51 that is close to and fixedly connected to the second worm gear 44. A third baffle 52 is provided on the side of the connecting plate 51 that is close to the flip handwheel 43. The third baffle 52 is an "L" shaped plate. The upper surface of the third baffle 52 is fixedly connected to one side of the connecting plate 51. The connecting plate 51 and the third baffle 52 are perpendicular.

[0040] A fourth baffle is provided on the side of the third baffle 52 away from the connecting plate 51. The fourth baffle is an "L"-shaped plate, and the third baffle 52 and the fourth baffle are fixedly connected and perpendicular to each other. The third baffle 52 and the fourth baffle form a space near the flip handwheel 43, so that the flip handwheel 43 does not touch the third baffle 52 and the fourth baffle when it rotates. The circuit breaker can be fixedly connected to the side of the connecting piece 53 away from the second worm gear 44.

[0041] When the rotating handwheel 43 is turned, the rotating handwheel 43 drives the second worm wheel 42 to rotate, the second worm wheel 42 drives the second worm 44 to rotate, and the second worm 44 drives the connecting piece 5 to rotate. Since the second worm wheel 42 drives the second worm 44 to rotate, it can form a self-locking mechanism on the second worm 44, so that the connecting piece 5 can form a self-locking structure when rotating.
