Referring to fig. 1 and 2, an embodiment of the present application provides a running cart 100. The running cart 100 includes: drive portion 110, base 120, support portion 130, and scissor jack 140. The driving portion 110 is used for driving the scissors telescoping mechanism 140 to telescope in a first direction. One end of the scissor telescopic mechanism 140 along the first direction is connected with the base 120, and the other end along the first direction is connected with the supporting portion 130, and the supporting portion 130 is used for supporting the switch trolley.

When the above-mentioned running cart 100 runs the switching cart, since one end of the scissors telescoping mechanism 140 along the first direction (vertical direction in actual use) is connected to the base 120, and the other end along the first direction (Y) is connected to the supporting portion 130, when the driving portion 110 drives the scissors telescoping mechanism 140 to telescope along the first direction (Y), the scissors telescoping mechanism 140 drives the supporting portion 130 to move along the first direction (Y), and then the position of the supporting portion 130 along the first direction (Y) can be adjusted. Until the position of the supporting portion 130 along the first direction (Y) is equivalent to the position of the switching trolley to be operated along the first direction (Y), the worker can conveniently place the switching trolley on the supporting portion 130 of the operating trolley 100, so as to conveniently operate the switching trolley. Because the height positions of the switch trolleys in the switch cabinets of different equipment along the first direction (Y) are different, the switch trolleys at different positions can be adapted by adjusting the positions of the supporting parts 130 along the first direction (Y), so that the operation trolleys 100 of various specifications are not required, and the operation is convenient.

Specifically, in the present embodiment, the driving portion 110 may be an air cylinder, one end of the air cylinder is connected to the base 120, and the other end of the air cylinder is connected to one scissor blade 1411 of the scissor telescopic mechanism 140. When the cylinder is extended or shortened, the scissor blade 1411 can be driven to rotate, so that the scissor telescopic mechanism 140 can be driven to stretch along the first direction (Y). Of course, the driving portion 110 may be another linear extending and retracting mechanism, such as a hydraulic cylinder, as long as the scissor extending and retracting mechanism 140 can be driven to extend and retract along the first direction (Y). The support portion 130 may be a support plate, a support block, etc., as long as it can support the opening and closing cart.

Referring to fig. 1, in an embodiment, the running carriage 100 further includes two limiting sliding rails 150, the limiting sliding rails 150 are disposed on the supporting portion 130, and the two limiting sliding rails 150 are disposed at intervals along a second direction (X), and the second direction (X) is perpendicular to the first direction (Y). Specifically, when the position of the supporting portion 130 along the first direction (Y) is the same as the position of the switch trolley to be operated along the first direction (Y), the worker only needs to push the switch trolley onto the two limit slide rails 150, so that the pulleys of the switch trolley are respectively matched with the two limit slide rails 150, and the limit slide rails 150 can limit the positions of the pulleys of the switch trolley along the second direction (X), thereby positioning the switch trolley on the supporting portion.

Further, because the limit slide rails 150 adopt a slide rail structure, the pulleys connected with the lower end of the switch trolley along the first direction (Y) can roll along the corresponding limit slide rails 150, so that the switch trolley can be pushed onto the two limit slide rails 150 in a more labor-saving manner.

Referring to fig. 1, in an embodiment, side plates 151 are respectively disposed on sides of the two limiting slide rails 150 away from each other. When the switch trolley is pushed onto the limit slide rail 150, the side plate 151 is used for blocking the switch trolley along the second direction (X), so that the switch trolley is prevented from moving along the second direction (X) due to uneven stress, and the switch trolley is prevented from being separated from the limit slide rail 150.

Referring to fig. 1, in an embodiment, two scissor assemblies 140 are provided and spaced along a third direction (Z), and the third direction (Z) is perpendicular to the first direction (Y) and the second direction (X), respectively. Specifically, because two scissor telescoping mechanisms 140 are arranged at intervals along the third direction (Z), the two scissor telescoping mechanisms 140 make the connection between the base 120 and the bearing portion 130 more reliable, and can more reliably support the bearing portion 130, thereby more reliably supporting the switch trolley. Moreover, when the two scissors telescoping mechanisms 140 extend and retract, the support portion 130 can be more strongly driven to adjust the position in the first direction (Y).

In other embodiments, the scissor telescopic mechanism may be three, four, or the like, as long as the support portion 130 can be stably supported.

Referring to fig. 1 and 2, in an embodiment, each scissor jack 140 includes a scissor jack 141, each scissor jack 141 includes two intersecting scissor blades 1411, the two intersecting scissor blades 1411 are pivotally connected at an intersection, and the two intersecting scissor blades 1411 are capable of rotating around the intersection. Since the two mutually crossing scissor blades 1411 can rotate at different angles along the rotation connection, the height of the scissor telescopic mechanism 140 in the vertical direction can be changed, and the support 130 can be driven to move in the vertical direction.

The upper ends of the two mutually intersecting scissor elements 1411 in the first direction (Y) are slidably connected to the support 130, and the lower ends of the two mutually intersecting scissor elements 1411 in the first direction (Y) are slidably connected to the base 120. When the scissor telescoping mechanism 140 extends and contracts, the two intersecting scissor blades 1411 rotate relatively, so that the upper ends of the two intersecting scissor blades 1411 approach to each other or move away from each other, and the upper ends of the two intersecting scissor blades 1411 in the first direction (Y) slide relatively to the support portion 130, respectively, so that the scissor telescoping mechanism 140 extends and contracts. Similarly, the lower ends of the two mutually crossed scissors blades 1411 approach to or are away from each other, and the lower ends of the two mutually crossed scissors blades 1411 along the first direction (Y) respectively slide relative to the base 120, so that the scissors telescoping mechanism 140 realizes telescoping.

In other embodiments, each scissor telescoping mechanism may also include a plurality of scissor telescoping units connected in series along the first direction (Y), for example, two or more scissor telescoping units, and the adjustable range of the plurality of scissor telescoping units is wider, so that the scissor telescoping mechanism can be applied to a switch trolley at a higher position.

The upper ends of the two mutually intersecting scissor elements at the uppermost ends of the scissor telescopic units sequentially connected in the first direction (Y) are respectively connected with the support part in a sliding manner, and the lower ends of the two mutually intersecting scissor elements at the lowermost ends of the scissor telescopic units sequentially connected in the first direction (Y) are respectively connected with the base in a sliding manner.

Referring to fig. 1, in an embodiment, the supporting portion 130 is provided with a sliding slot 101, and the limiting sliding rail 150 is provided with a sliding block (not shown), and the sliding block is slidably engaged with the sliding slot 101 along the second direction (X). Specifically, the slider and the sliding groove 101 are in sliding fit along the second direction (X), and the distance between the two limit sliding rails 150 can be adjusted, so that the switch trolleys of different sizes and specifications can be adapted, and the adaptability of the running trolley 100 is improved.

In other embodiments, the limiting slide rails may be provided with sliding grooves, the supporting portion is provided with sliding blocks, and the sliding blocks and the sliding grooves are in sliding fit along the second direction, so that the distance between the two limiting slide rails can be adjusted.

Referring to fig. 1, in one embodiment, the running carriage 100 further includes a pad 160. The cushion block 160 is disposed on the supporting portion 130 and located between the two limit sliding rails 150. Specifically, since the pad 160 is located between the two limit slide rails 150, the weight of the switching cart can be supported, the two limit slide rails 150 are prevented from being damaged due to excessive stress, and the support portion 130 is prevented from being bent due to unbalanced stress.

Referring to fig. 1, in an embodiment, the running carriage 100 further includes a push rod 170, and the push rod 170 is connected to the base 120 and the supporting portion 130. Specifically, the push rod 170 can push the running cart 100 to move, thereby facilitating the transfer of the switch cart to the maintenance location.

Referring to fig. 1, in an embodiment, the running carriage 100 further includes a sleeve 180, the sleeve 180 is connected to the supporting portion 130, and the sleeve 180 is sleeved on the push rod 170. Specifically, when the scissors telescoping mechanism 140 drives the supporting portion 130 to move along the first direction (Y), because the sleeve 180 is connected to the supporting portion 130 and the sleeve 180 is sleeved on the push rod 170, when the supporting portion 130 moves along the first direction (Y), the sleeve 180 can be driven to move along the first direction (Y) relative to the push rod 170, so that even if the supporting portion 130 adjusts the position along the first direction (Y), the push rod 170 can still be connected to the supporting portion 130, and the push rod 170 does not block the supporting portion 130 from adjusting the position along the first direction (Y).

Further, the running carriage 100 further comprises a rib plate 181. The rib plate 181 is fixedly connected to the support portion 130 and is fixedly connected to the sleeve 180. Because the rib plate 181 is fixedly connected with the support part 130 and fixedly connected with the sleeve 180, the connection strength between the sleeve 180 and the support part 130 can be increased, the sleeve 180 is prevented from being separated from the support part 130 due to the overlarge stress of the sleeve 180, and the connection is more reliable. In this embodiment, the rib 181 is substantially triangular.

Referring to fig. 1-3, in an embodiment, the running carriage 100 further includes a plurality of rollers 121, and the plurality of rollers 121 are respectively connected to the base 120. The roller 121 can convert the sliding friction between the base 120 and the ground into the rolling friction between the roller 121 and the ground, so that the friction between the roller 121 and the ground is reduced, and the running trolley 100 can be pushed to move in a more labor-saving manner. In the present embodiment, the number of the rollers 121 is four.

Referring to fig. 3, in an embodiment, the operation trolley 100 further includes a power supply 190, and the power supply 190 is connected to the driving portion 110 and can supply power to the driving portion 110, so that the driving portion 110 can drive the scissors telescoping mechanism 140 to move.

Referring to fig. 3, in an embodiment, the running carriage 100 further includes a control panel 191, the control panel 191 is connected to the power source 190, and the control panel 191 is used for controlling the driving portion 110. Specifically, the power supply 190 is connected to a driving panel 191, and the driving panel 191 is used for controlling the driving portion 110, so that the adjustment data is input to the driving panel 191, and the driving portion 110 responds accordingly to drive the scissors telescoping mechanism 140 to telescope by a corresponding distance, so that the supporting portion 130 adjusts the corresponding height. The height of the supporting part 130 can be accurately adjusted by adopting the control panel 191, and the use is convenient.

Referring to FIG. 3, in one embodiment, the trolley 100 further includes an accessory box 122 capable of holding conventional components and tools, such as screws, nuts, etc.

Referring to fig. 3, in an embodiment, the running carriage 100 further includes a fixing portion 161, and the fixing portion 161 is used for fixing a relative position between the switch cabinet and the running carriage 100. Specifically, when the operation trolley 100 operates the switch trolley from the switch cabinet, the fixing portion 161 is fixedly connected with the switch cabinet, so that the operation trolley 100 can be prevented from moving relative to the switch cabinet when the switch trolley is pushed into the operation trolley 100, and the operation is more convenient.

In this embodiment, the fixing portion 161 may be a hook, and the hook may be connected to the cushion block 160 and extend out of an end of the cushion block 160 away from the push rod 170, so that the hook does not need to be separately fixed, and the operation is convenient and the space is saved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
