Description

Technical Field

[0002] The statements in this section merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] When the substation operation and maintenance personnel switch the equipment in the substation from operation to maintenance, they need to move the high-voltage grounding trolley. The previous practice was that the operating personnel manually moved the high-voltage grounding trolley out of the operating site, which was difficult to operate and prone to safety accidents. Now mobile trolleys are mostly used to move the trolleys, but there are still some problems.

[0004] First, when aligning the mobile trolley with the cabinet rail, the trolley is prone to rigid collision with the rail, especially when the trolley is already carrying a handcart, which can easily knock the cabinet rail crooked;

Especially for simple routine maintenance, the trolley still needs to be moved to a special operating position for maintenance. The trolley cannot be pulled out on the spot for maintenance, which increases the safety risks during transportation and loading and unloading of the trolley, as well as the workload of aligning the trolley rails with the cabinet rails at a later time.

[0031] Compared with the prior art, the beneficial effects of this application are:

[0032] (1) The present application divides the mobile trolley into a load-bearing body and a docking body through a clutch mechanism, and actively docks the high-voltage cabinet rails through the docking body to prevent the mobile trolley from colliding with the rails. The load-bearing body and the docking body are movably connected to prevent the docking body from applying a lateral pulling force to the rails when the docking body is connected to the high-voltage cabinet conductor, thereby preventing the rails from bending and affecting the trolley from entering and exiting the high-voltage cabinet along the rails, thereby ensuring the safety of the trolley's movement.

[0033] (2) The present application realizes the clutch and movable connection between the load-bearing vehicle body and the docking vehicle body through a movable connecting rod, a latch mechanism and a locking pin mechanism. The user can connect the docking vehicle body to the high-voltage cabinet rail, and after the trolley moves to the load-bearing seat, the load-bearing vehicle body and the docking vehicle body are separated by the clutch mechanism. The movable connecting rod makes way for the maintenance position between the high-voltage cabinet body and the load-bearing vehicle body while ensuring the continuity of the connection between the docking vehicle body and the high-voltage cabinet rail. After the main lifting mechanism is used to inspect the trolley, the workload of secondary alignment of the rail is avoided, which facilitates on-site inspection after the trolley is pulled out of the high-voltage cabinet, and avoids safety risks during transportation and loading and unloading of the trolley.

[0034] (3) Since it is necessary to ensure that the heights of the load-bearing car body, the docking car body, and the high-voltage cabinet guide rails are flush or nearly flush, the thickness of the load-bearing car body and the docking car body cannot be increased, which limits the possibility of the lifting mechanism to transfer to the bottom of the load-bearing car body. The present application uses a structure in which a main drive motor drives four main drive screws, which not only realizes the function of the top lifting trolley, but also reduces the cost of the lifting mechanism on the basis of ensuring the realization of a smooth lifting function.

The four corners of the bearing seat 63 are respectively connected to the main driving screws 610, and a push-pull mechanism 7 for pushing and pulling the trolley is arranged on the U-shaped connecting rod seat 62.

[0057] The rear part of the docking vehicle body 2 is provided with a docking mechanism 4 for docking with the guide rail 200 of the high-voltage cabinet 100, and a clutch mechanism for active connection between the docking vehicle body 2 and the supporting vehicle body 1 is provided between the docking vehicle body 2 and the supporting vehicle body 1.

[0058] When the bearing seat 63 moves to the bottom of the installation groove, the top height of the bearing seat 63 is flush with the top of the bearing body 1 and the docking body 2, and the left and right sides of the top of the bearing body 1, the bearing seat 63, and the docking body 2 are provided with front-to-back trolley slide grooves 9, and the U-shaped connecting rod seat 62 is also provided with a control box electrically connected to the main lifting mechanism 6, the push-pull mechanism 7, the clutch mechanism, and the docking mechanism 4.

[0059] The present application divides the mobile trolley into a load-bearing body 1 and a docking body 2 through a clutch mechanism, and actively docks the guide rail 200 of the high-voltage cabinet 100 through the docking body 2 to prevent the mobile trolley from colliding with the guide rail 200, and the load-bearing body 1 is movably connected to the docking body 2 to prevent the loaded load-bearing body 1 from moving and driving the docking body 2 to apply a lateral pulling force to the guide rail 200 when the docking body 2 is connected to the guide rail 200 of the high-voltage cabinet 100, so that the guide rail 200 is bent, affecting the trolley from entering and exiting the high-voltage cabinet 100 along the guide rail 200, thereby ensuring the safety of the trolley's movement. At the same time, the user can After the docking car body 2 is connected to the guide rail 200 of the high-voltage cabinet 100, the trolley moves to the bearing seat 63, and then the bearing car body 1 and the docking car body 2 are separated by the clutch mechanism. The clutch mechanism makes way for the inspection position between the high-voltage cabinet 100 and the bearing car body 1 while ensuring the continuity of the connection between the docking car body 2 and the guide rail 200 of the high-voltage cabinet 100. After the trolley is inspected and repaired in cooperation with the main lifting mechanism 6, the workload of secondary alignment of the guide rail 200 is avoided, which facilitates on-site inspection after the trolley is pulled out of the high-voltage cabinet 100, and avoids safety risks during transportation and loading and unloading of the trolley.

[0060] Specifically, the main lifting mechanism 6 includes a main driving box 65 arranged on the front side of the U-shaped connecting rod seat 62, and the first driving rod 66 is arranged on the left and right sides of the main driving box 65. The left and right ends of the first driving rod 66 are arranged with a first transmission box 67, and the rear side of the first transmission box 67 is connected to the second driving rod 68, and two second transmission boxes 69 are arranged on the second driving rod 68. The main driving screw 610 is connected to the bottom of the second transmission box 69.

[0061] The main drive box 65 is provided with a main drive motor and a first gear set for driving the first drive rod 66, the first transmission box 67 is provided with a second gear set for transmission connection between the first drive rod 66 and the second drive rod 68, the second transmission box 69 is provided with a worm gear structure for transmission connection between the second drive rod 68 and the main drive screw 610, and the first drive rod 66, the first transmission box 67, the second drive rod 68, and the second transmission box 69 are sequentially embedded in the U-shaped connecting rod seat 62.

[0062] The main drive motor drives the first drive rod 66 to rotate through the first gear set, and then drives the two second drive rods 68 to rotate through the second gear set, and then drives the four main drive screws 610 to rotate through the worm gear, thereby realizing the lifting and lowering of the support seat 63.

[0063] Preferably, a support column 64 connected to the top of the supporting vehicle body is provided at the bottom of the main driving box 65 .

[0065] When the trolley needs to be pulled out of the high-voltage cabinet 100, the displacement guide rail drives the main telescopic cylinder 71 to move to the rear end of the guide rail groove 621, and the telescopic shaft of the main telescopic cylinder 71 extends to connect the grabbing mechanism 72 to the corresponding position of the trolley. The telescopic shaft of the main telescopic cylinder 71 retracts to pull the trolley out, and the movement of the slider of the displacement guide rail drives the roller of the trolley to move along the trolley slide groove 9 to the bearing seat 63. Conversely, the trolley can be pushed into the high-voltage cabinet 100.

[0066] The displacement guide rail is used to reduce the length of the main telescopic cylinder 71, the lifting cylinder 74 is used to drive the main telescopic cylinder 71 to adapt to the height of different trolley grabbing positions, and the first multi-stage telescopic rod 76 and the second multi-stage telescopic rod 77 are used to keep the posture of the main telescopic cylinder 71 stable during movement.

[0067] The structure of the grabbing mechanism 72 can be changed according to the structure of the grabbing position of the trolley. A typical and universal configuration is an electromagnet, and the connection between the grabbing mechanism 72 and the trolley is completed by the adsorption of the electromagnet.

[0069] The opposite end faces of the load-bearing body 1 and the docking body 2 are also provided with locking grooves, a latch mechanism 11 is provided in the locking groove on the load-bearing body 1, and a locking pin mechanism is provided in the locking groove on the docking body 2, the latch mechanism 11 includes a first telescopic mechanism connected to the side wall at the end of the locking groove and a latch seat provided at the end of the first telescopic mechanism, locking through holes are provided on the left and right side walls of the latch seat, the locking pin mechanism includes a second telescopic mechanism connected to the left or right wall of the locking groove, a pin is provided at the end of the telescopic shaft of the second telescopic mechanism, and the pin is movably inserted in the locking through hole.

[0070] The clutch mechanism includes a movable link 5, a latch mechanism 11 and a lock pin mechanism. When the load-bearing body 1 and the docking body 2 are aligned and connected, the movable link 5 is completely hidden in the docking groove 51, and the latch mechanism 11 and the lock pin mechanism are completely hidden in the locking groove.

[0071] When the carrying body 1 and the docking body 2 need to be locked and fixed, the user pushes the carrying body 1 to move so that the docking groove 51 and the locking groove on the carrying body 1 and the docking body 2 are aligned with each other, and the first telescopic mechanism drives the latch seat to insert into the locking groove on the opposite side, and the second telescopic mechanism drives the pin to insert into the locking through hole to achieve the locking and fixing of the carrying body 1 and the docking body 2.

[0072] As shown in Figure A, the movable connecting rod 5 is a two-stage hinged connecting rod. The loaded carrying body 1 will not affect the docking body when it moves. When the docking body 2 is connected to the guide rail 200 of the high-voltage cabinet 100, the trolley moves to the bearing seat 63. The user can pull the carrying body 1 away from the docking body 2 to make room for the inspection and maintenance position between the high-voltage cabinet 100 and the carrying body 1 while ensuring the continuity of the connection between the docking body 2 and the guide rail 200 of the high-voltage cabinet 100. After cooperating with the main lifting mechanism 6 to inspect the trolley, the workload of secondary alignment of the guide rail 200 is avoided, which facilitates on-site inspection after the trolley is pulled out of the high-voltage cabinet 100.

[0073] Preferably, the opposite end surfaces of the two straight arms of the U-shaped connecting rod seat 62 are symmetrically provided with a holding mechanism 10, and the holding mechanism 10 includes a holding telescopic mechanism and an elastic pressure plate arranged at the end of its telescopic shaft. When the trolley is pulled onto the bearing seat 63, the holding telescopic mechanism drives the elastic pressure plate to elastically clamp the side wall of the trolley to enhance the stability of the trolley on the bearing seat 63. Furthermore, a lifting block that limits the displacement of the trolley roller is provided in the trolley slide groove on the bearing seat 63.

[0074] Specifically, four moving wheels 3 are arranged at the four corners of the bottom of the carrying body 1, and two moving wheels 3 are arranged at the bottom of the docking body 2. The two moving wheels 3 arranged at the rear side of the carrying body 1 and the two moving wheels 3 at the bottom of the docking body 2 are brakeable universal wheels.

[0077] The clamping driving screw 42 includes a clamping motor and a screw body.

[0078] The user pushes this application to the front of the high-voltage cabinet so that its guide rail 200 is located between the two clamping blocks 43. The clamping drive screw 42 rotates to drive the circulating drive belts 44 on the two clamping blocks 43 to clamp the corresponding guide rail 200. The circulating drive belt 44 is controlled to start, and the friction between the circulating drive belt 44 and the guide rail 200 can drive the rear end of the docking vehicle body 2 to contact the front end of the guide rail 200, so that the guide rail 200 is aligned with the trolley slide groove 9 of the docking vehicle body 2.

[0079] The circulating driving belt 44 may be a conveyor belt mechanism.

[0080] Based on the above portable mobile device, the present application also provides a portable mobile method for a high-voltage grounding trolley, and the specific steps are as follows:

[0081] S100: The user moves the mobile vehicle body to a position relative to the front of the high-voltage cabinet 100, and controls the clutch mechanism through the control box to separate the carrying vehicle body 1 from the docking vehicle body 2;

[0082] S200: The control box controls the docking mechanism 4 on the docking vehicle body 2 to dock with the external guide rail 200 of the high-voltage cabinet 100. After the docking is completed, the user pushes the carrying vehicle body 1 to contact the docking vehicle body 2, and the carrying vehicle body 1 and the docking vehicle body 2 are locked and combined through the clutch mechanism;

[0083] S300: The control box controls the push-pull mechanism 7 to pull out or push in the hand car;

[0084] S400: When the push-pull mechanism 7 moves the trolley onto the supporting seat 63 in step S300, the supporting seat 63 can be driven to rise to a preset position by the main lifting mechanism 6 to inspect the bottom of the trolley.

[0085] The steps S100 to S300 are a general method for pulling out or pushing in the trolley. When the load-bearing body 1 is not load-bearing and the trolley is pulled out, since the load-bearing body 1 is relatively light, the connection between the load-bearing body 1 and the docking body 2 can be maintained, and the docking of the docking body 2 and the guide rail 200 of the high-voltage cabinet 100 is directly completed through the docking mechanism 4.

[0086] In the step S400, when the docking vehicle body 2 is connected to the guide rail 200 of the high-voltage cabinet 100 and the trolley moves to the supporting seat 63, the user can pull the supporting vehicle body 1 away from the docking vehicle body 2 to make room for an inspection and maintenance position between the high-voltage cabinet 100 and the supporting vehicle body 1 while ensuring the continuity of the connection between the docking vehicle body 2 and the guide rail 200 of the high-voltage cabinet 100, and inspect the trolley in cooperation with the main lifting mechanism 6.

[0087] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
