Description

Technical Field

[0001] The utility model relates to an intelligent transport trolley for high-voltage vacuum circuit breakers, and relates to the technical field of transport equipment. Background Art

[0002] The rated current of the 10KV vacuum circuit breaker in the high-voltage switchgear ranges from 630A to 3150A, and the heaviest one weighs nearly 300 kilograms. It is difficult and unsafe to carry it manually, so transfer carts are installed in the distribution room.

[0003] The existing distribution rooms all use conventional transfer trolleys with a fixed height and fixed width mechanical structure. The equipment is relatively simple, easy to process, and low in cost. However, when transferring the circuit breaker in the switch cabinet, the transfer trolley and the switch cabinet need to be aligned in height and level. The conventional transfer trolley can only be adjusted by manually rotating the screw. Due to the heavy weight of the circuit breaker, the alignment adjustment is difficult and the work efficiency is low. Moreover, one transfer trolley is only suitable for transporting circuit breakers of the same height and breaking width (the various cabinet types of circuit breakers in the distribution room have different high voltages and widths), which has great limitations. A substation often requires multiple transfer trolleys, which take up a lot of space. Circuit breakers with matching heights need to be selected according to the installation height of the circuit breaker. Moreover, during the transportation of circuit breakers at a higher position, there is a risk of overturning or falling due to the high center of gravity, which endangers the personal safety of operation and maintenance personnel and equipment. In addition, the bottom of the circuit breaker support of the existing transfer trolley is closed. When the bottom position of the circuit breaker needs to be repaired, it needs to be transported to another position again, which increases the workload and transportation risks.

DETAILED DESCRIPTION

[0026] Reference Figures 1-8 The technical scheme adopted in the specific embodiment is shown in the figure: it comprises a transfer trolley body 1, which comprises an active lifting column 11 and a driven lifting column 12, the active lifting column 11 and the driven lifting column 12 are connected through a synchronous belt transmission, and each is provided with a support arm 4. In this embodiment, there is a communication cavity between the two lifting columns, and a synchronous belt is arranged in the communication cavity to connect the two lifting columns, so that the active lifting column can drive the driven lifting column to synchronously drive the two support arms to lift.

[0027] A translation mechanism 3 is arranged on the support arm 4, and an adjustable tray mechanism 2 is arranged on the translation mechanism 3. By arranging the translation mechanism, the adjustable tray mechanism can be driven to translate thereon, which facilitates further alignment adjustment with the circuit breaker after the height adjustment is completed, so as to ensure that the circuit breaker can be accurately moved to the adjustable tray mechanism.

[0028] More specifically, the translation mechanism 3 comprises a bottom plate 31, which is a frame structure. The middle part of the bottom plate 31 is provided with a translation rail 33, and the translation rail 33 is slidably provided with a translation bracket 32. In this embodiment, the bottom plate is a frame structure, and has a large area of slot on it. When the circuit breaker is turned to the adjustable tray mechanism, the circuit breaker can be directly repaired from the bottom without the need to transfer it to the maintenance table, which can greatly improve the work efficiency and solve the problem of difficult maintenance.

[0029] A limit wheel 34 is arranged on the translation bracket 32, and a mounting groove 25 is arranged at the bottom center of the adjustable tray mechanism 2. The mounting groove 25 is connected with the limit wheel 34 in a matched manner. The adjustable tray mechanism is connected with the limit wheel through the mounting groove. A notch can be arranged on the mounting groove to match the limit wheel, which can facilitate the connection and positioning. At the same time, after the limit wheel is connected with the mounting groove, the entire adjustable tray mechanism can also be driven to translate.

[0030] The support arm 4 is provided with a laser radar 5 at the front end, and the model is T50 three-dimensional depth imaging laser radar.

[0031] In the present embodiment, when the circuit breaker is transported, first move the transport trolley body to the relative position of the circuit breaker to be transported, press the switch to power on the device, the device performs self-checking, and all mechanisms are reset. At this time, according to the width of the circuit breaker to be transported, select the corresponding size on the control panel, and the adjustable tray is automatically adjusted to the corresponding width. Then, by selecting the height, control the driving lifting column to drive the driven lifting column to lift, thereby driving the translation mechanism to lift to the position of the circuit breaker. After the translation mechanism moves to the height of the circuit breaker, the laser radar is automatically turned on for alignment. The laser radars on both sides perform three-dimensional imaging alignment on the circuit breaker, and the alignment data is returned to the control mainboard. When the position of the laser radar is aligned with the edge of the circuit breaker during scanning, the circuit breaker can be pulled out for transportation after the alignment is completed. If the position of the laser radar is not aligned with the edge of the circuit breaker, the control mainboard sends control information to drive the translation mechanism to move slowly horizontally. The laser radar continues to scan and detect until the alignment is accurate, and the control mainboard sends a stop signal to the translation mechanism. At this time, the adjustable tray is aligned with the circuit breaker, and the circuit breaker can be pulled out for transportation. During the entire operation process, the operator only needs to move the transport trolley body to the position of the circuit breaker to be transported and set the corresponding height and width. The device automatically adjusts the height and position, and the circuit breaker can be pulled out directly after adjustment. The overall degree of automation is high, the working intensity of the operator is low, and the safety is higher.
