[0027] 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 those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Example 1

[0029] This embodiment provides a 10kV handcart switch operating cart, such as... Figures 1-5 ,

[0030] It includes an operating vehicle 100, the bottom of which is fixedly connected to a track assembly 200; the track assembly 200 includes a bracket 201, a moving mechanism 202, and a connecting mechanism 203, the moving mechanism 202 being located inside the bracket 201, the connecting mechanism 203 being located on one side of the moving mechanism 202, and the operating vehicle 100 being fixed to the moving mechanism 202; and a crank assembly 300, which cooperates with the connecting mechanism 203.

[0031] The support 201 is a rectangle composed of two parallel horizontal bars 201a and two parallel vertical bars 201b. Tracks 201b-1 are provided on the two vertical bars 201b, and one end of the moving mechanism 202 moves in the tracks 201b-1.

[0032] The moving mechanism 202 includes a rotating shaft 202a, a slider 202b, a connecting rod 202c, a support block 202d, and a pulley 202e. One end of the rotating shaft 202a is rotatably connected to a bracket 201, and the other end of the rotating shaft 202a is fixedly connected to a connecting mechanism 203. The rotating shaft 202a has an external thread, and the slider 202b has a through hole with an internal thread. The slider 202b is threadedly connected to the rotating shaft 202a. The connecting rod 202c is fixedly fixed at both ends of the slider 202b. The end of the connecting rod 202c away from the slider 202b is fixedly connected to the support block 202d. The bottom of the support block 202d has a pulley 202e, which moves in the track 201b-1.

[0033] A horizontal bar 201a and a vertical bar 201b form a rectangular support 201. A track 201b-1 is provided on the vertical bar 201b. A moving mechanism 202 drives the operating trolley 100 to move within the track 201b-1. A crank assembly 300 is connected to the moving mechanism 202 via a connecting mechanism 203, thereby enabling the moving mechanism 202 to move the operating trolley 100 by operating the crank assembly 300.

[0034] The rotating shaft 202a and the slider 202b in the moving mechanism 202 are connected by a thread. Therefore, when the rotating shaft 202a rotates, the slider 202b will move along the axis of the rotating shaft 202a. Then, the slider 202b will drive the support block 202d to move in the track 201b-1 through the connecting rod 202c. The operating cart 100 is fixed on the upper end of the support block 202d. Therefore, the rotation of the rotating shaft 202a can drive the operating cart 100 to move in the axis of the rotating shaft 202a.

[0035] The connecting mechanism 203 includes a fixing plate 203a and a first connecting member 203b. The fixing plate 203a is fixedly connected to the bracket 201, and the first connecting member 203b is fixedly connected to the fixing plate 203a. The first connecting member 203b is located in the center of the fixing plate 203a.

[0036] The crank assembly 300 includes a crank 301 and a second connector 302, the second connector 302 being fixedly connected to one end of the crank 301.

[0037] The first connector 203b is a hexagonal protrusion, and the second connector 302 is a hexagonal groove.

[0038] The crank handle 301 includes a first rod 301a, a second rod 301b, and a third rod 301c. One end of the first rod 301a is fixedly connected to the second rod 301b, and the first rod 301a and the second rod 301b are perpendicular to each other. The end of the second rod 301b away from the first rod 301a is fixedly connected to the third rod 301c, and the second rod 301b and the third rod 301c are perpendicular to each other. The first rod 301a and the third rod 301c are parallel to each other. The axes of the first rod 301a, the second rod 301b, and the third rod 301c are located in the same plane. The second connecting member 302 is disposed at the end of the third rod 301c away from the second rod 301b.

[0039] The first connector 203b is a hexagonal protrusion, and the second connector 302 is a hexagonal groove. The first connector 203b and the second connector 302 are inserted into each other. The fixed plate 203a is fixedly mounted on one side of the moving mechanism 202. When the first connector 203b and the second connector 302 are inserted into each other, the crank handle 301 is connected to the fixed plate 203a. At this time, turning the crank handle 301 can move the operating vehicle 100.

[0040] Example 2

[0041] This embodiment provides a 10kV handcart switch operating cart, such as... Figures 5-8 This embodiment is based on Embodiment 1, but differs from Embodiment 1 in that:

[0042] The crank handle 301 is provided with a stabilizing component 303, which includes a housing 303a, a support foot 303b, a tensioning mechanism 303c, and a clamping mechanism 303d. The housing 303a is rotatably connected to the crank handle 301, and the housing 303a has a cavity inside. The tensioning mechanism 303c is located in the cavity. One end of the support foot 303b is fixedly connected to the outer wall of the housing 303a, and the clamping mechanism 303d is located at the end of the support foot 303b away from the housing 303a.

[0043] The stabilizing component 303, using the support foot 303b, ensures that the crank handle 301 remains relatively stable during cranking, preventing it from easily detaching from the fixed plate 203a. During cranking, the tensioning mechanism 303c is tightened, causing the clamping mechanism 303d to clamp the handle, firmly securing it to the fixed plate 203a. When the cranking operation is finished, the tensioning mechanism 303c is released, disengaging the clamping mechanism 303d and allowing the handle to easily detach from the fixed plate 203a.

[0044] The tensioning mechanism 303c includes a centrifugal component 303c-1 and a rotating component 303c-2. The centrifugal component 303c-1 is sleeved on the crank handle 301, and the rotating component 303c-2 is disposed outside the centrifugal component 303c-1. The centrifugal component 303c-1 includes an inner ring 303c-11, a first spring 303c-12, a plurality of first throwing blocks 303c-13, and a plurality of second throwing blocks 303c-14. The inner ring 303c-11 is fixedly sleeved on the third rod 301c. The inner ring 303c-11 is provided with an annular groove. The plurality of first throwing blocks 303c-13 are evenly distributed in the annular groove. One end of the plurality of first throwing blocks 303c-13 is movably connected in the annular groove. One side of the first throwing block 303c-13 is connected to the bottom surface of the annular groove by a first spring 303c-12.

[0045] Several second throwing blocks 303c-14 are evenly distributed in the annular groove. One end of several second throwing blocks 303c-14 is movably connected in the annular groove. One side of the second throwing block 303c-14 is connected to the bottom surface of the annular groove by a first spring 303c-12. The first throwing block 303c-13 and the second throwing block 303c-14 are distributed in opposite directions in the annular groove.

[0046] The rotating component 303c-2 includes an outer ring 303c-21, a fixing block 303c-22, a second spring 303c-23, and a pull rope 303c-24. The inner ring of the outer ring 303c-21 has a groove. The ends of the first throwing block 303c-13 and the second throwing block 303c-14 furthest from the groove are aligned with the groove. The outer ring 303c-21 is sleeved on the outside of the inner ring 303c-11. Two fixing blocks 303c-22 are symmetrically arranged on the outer side of 3c-21. One end of a pull rope 303c-24 is fixedly connected to each of the two fixing blocks 303c-22. The other end of the pull rope 303c-24 passes through the outer shell 303a and is fixedly connected to the clamping mechanism 303d. One end of the second spring 303c-23 is fixedly connected to the fixing block 303c-22, and the other end of the second spring 303c-23 is fixedly connected to the inner wall of the outer shell 303a.

[0047] The clamping mechanism 303d includes a first clamping plate 303d-1, a second clamping plate 303d-2, and a third spring 303d-3. The first clamping plate 303d-1 is fixedly connected to the end of the support foot 303b away from the outer shell 303a. The second clamping plate 303d-2 is sleeved on the support foot 303b and is slidably connected to the support foot 303b. The third spring 303d-3 is provided between the second clamping plate 303d-2 and the first clamping plate 303d-1. The pull rope 303c-24 passes through the first clamping plate 303d-1 and the third spring 303d-3 and is fixedly connected to the second clamping plate 303d-2. The first clamping plate 303d-1 and the second clamping plate 303d-2 are located on both sides of the fixing plate 203a.

[0048] Both the first throwing block 303c-13 and the second throwing block 303c-14 are rotatably connected at one end to the annular groove, meaning that a pin is provided in the annular groove. The bottom of both the first throwing block 303c-13 and the second throwing block 303c-14 has a circular hole. The first throwing block 303c-13 and the second throwing block 303c-14 are fitted onto the pin, meaning that the first throwing block 303c-13 and the second throwing block 303c-14 can rotate about the pin. When the inner ring 303c-11 rotates, the first throwing block 303c-13 and the second throwing block 303c-14... Under the action of centrifugal force, the end of the first throwing block 303c-13 and the second throwing block 303c-14 away from the inner ring 303c-11 tends to move away from the inner ring 303c-11. That is, under the action of centrifugal force, the ends of the first throwing block 303c-13 and the second throwing block 303c-14 away from the inner ring 303c-11 move towards the groove of the outer ring 303c-21 until the first throwing block 303c-13 and the second throwing block 303c-14 contact the groove of the outer ring 303c-21. During this process, the first spring 303c-12 is stretched.

[0049] Since the first throwing block 303c-13 and the second throwing block 303c-14 are distributed in opposite directions within the annular groove, when the inner ring 303c-11 rotates clockwise, the end of the first throwing block 303c-13 away from the inner ring 303c-11 contacts the groove of the outer ring 303c-21, and then the outer ring 303c-21 begins to rotate clockwise under the action of friction. At this time, the second throwing block 303c-14 is tightly attached to the annular groove. When the inner ring 303c-11 rotates counterclockwise, the end of the second throwing block 303c-14 away from the inner ring 303c-11 contacts the groove of the outer ring 303c-21, and then the outer ring 303c-21 begins to rotate counterclockwise under the action of friction. At this time, the first throwing block 303c-13 is tightly attached to the annular groove.

[0050] When the outer ring 303c-21 rotates, the fixed block 303c-22 rotates under the action of the outer ring 303c-21. The pull rope 303c-24 is then pulled by the fixed block 303c-22. The pull rope 303c-24 is a rigid rope, which in turn pulls the clamping mechanism 303d at the other end of the pull rope 303c-24, clamping the fixed plate 203a. Two fixed blocks 303c-22 are provided, symmetrically distributed on the outer ring 303c-21. Each fixed block 303c-22 is equipped with a second spring 303c-23. The pull rope 303c-24 passes through the inside of the second spring 303c-23. Therefore, when the outer ring 303c-21 rotates, both second springs 303c-23 are stretched.

[0051] The second clamping plate 303d-2 is slidably connected to the support foot 303b, meaning that the second clamping plate 303d-2 can slide along the support foot 303b. Since the end of the pull rope 303c-24 away from the outer ring 303c-21 is fixedly connected to the second clamping plate 303d-2, when the pull rope 303c-24 is stretched, the second clamping plate 303d-2 moves towards the first clamping plate 303d-1 under the action of the pull rope 303c-24. That is, the first clamping plate 303d-1 and the second clamping plate 303d-2 clamp the fixing plate 203a, so the crank handle 301 is stably connected to the fixing plate 203a during operation.
