Description

Technical Field

[0001] This utility model relates to the technical field of circuit breaker transfer equipment in the power industry, and in particular to a 10-35kV electric anti-tipping intelligent handcart. Background Technology

[0002] Switchgear, also known as metal-enclosed switchgear, is a complete set of power distribution equipment that assembles relevant electrical equipment into a closed metal enclosure according to a specific circuit scheme. It is widely used in power distribution systems for receiving and distributing electrical energy. Switchgear can connect or disconnect parts of power equipment or lines according to the needs of the power grid operation, and can quickly disconnect the faulty parts when power equipment or lines fail, ensuring the normal operation of the fault-free parts of the power grid and the safety of equipment and maintenance personnel. Therefore, as a critical power distribution device, the safe and reliable operation of switchgear is crucial to the power system. The stable operation of switchgear is directly related to the stability of the power system and the interests of users, making its maintenance and repair particularly important.

[0003] Among various types of switchgear, 10-35kV switchgear has attracted much attention due to its high-voltage characteristics. This type of high-voltage switchgear is widely used in power transmission and distribution systems, especially in substations, industrial and mining enterprises, and large buildings. 10-35kV switchgear possesses several key functions, including circuit breaking, which can quickly interrupt current in the event of a power system fault, thereby protecting equipment from damage. In addition, it has short-circuit protection, which can immediately act upon detecting a short-circuit current to prevent equipment damage and fires caused by excessive current. Grounding is also an important component of 10-35kV switchgear, providing a safe current loop in the event of a fault, ensuring the safety of operators and equipment.

[0004] During routine or fault maintenance of 10-35kV switchgear, it is necessary to pull the floor-mounted circuit breakers outside the cabinet for transport. Traditional maintenance of floor-mounted circuit breakers usually requires multiple workers, which presents several problems:

[0005] 1. The handcart weighs approximately 300kg to 500kg, requiring significant inertia to be overcome during pull-out. The wheeled structure of the circuit breaker also generates considerable inertial force after pull-out. Due to limited space at the depot, there is a risk of collision.

[0006] 2. The height differences between different stations and cabinets are not suitable for a single mechanical tooling, and manual adjustment of the height difference is required for transportation;

[0007] 3. The floor-mounted structure of the circuit breaker results in a low operating position, which is not in line with ergonomic principles and thus reduces work efficiency. Utility Model Content

[0008] In view of this, the present invention aims to provide an electric anti-tipping intelligent handcart suitable for the maintenance of 10-35kV switchgear. This handcart has good environmental and model adaptability, and can be adjusted with multiple degrees of freedom in height, width, and tilt angle, thus fully meeting the application requirements of different working conditions and various brands of circuit breakers. At the same time, through its adaptable design with electric and electric assistance, it effectively reduces the labor intensity during operation, allowing for easy operation by a single worker.

[0009] To achieve the above objectives, this utility model provides a 10-35Kv electric anti-tipping smart handcart, including a frame with load-bearing casters. The key feature is that a circuit breaker transfer compartment is provided on the frame via a lifting crank device, and a circuit breaker push-pull device is also provided on the circuit breaker transfer compartment.

[0010] Furthermore, the lifting crank device includes two sets of housings arranged opposite each other on the frame, and each housing is equipped with a rotation power unit through a lifting adjustment unit.

[0011] Furthermore, the lifting adjustment unit includes a base, a lifting arm disposed on the base, and a mounting seat disposed on the lifting arm.

[0012] Furthermore, the rotary power unit includes a power output shaft connected to the circuit breaker transfer chamber, and a torque sensor is also provided on the output shaft.

[0013] Furthermore, the circuit breaker push-pull device includes a circuit breaker handle connecting unit, a left-right lateral movement force unit, a front-back push-pull power unit, and a quick-connect interface for connecting the circuit breaker transfer compartment, arranged sequentially from front to back.

[0014] Furthermore, handles are respectively installed on the frame via two sets of brackets on the left and right sides. A display controller with a human-machine interface is also installed on one set of brackets. The display controller is connected to the control circuit of the lifting crank device and the circuit breaker push-pull device.

[0015] Furthermore, the frame is also equipped with a drive and braking unit, and the handlebars are equipped with a power assist throttle, which is connected to the control circuit of the drive and braking unit.

[0016] Furthermore, a tool compartment is also provided between the left and right sets of supports.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] Figures 1 to 5The first embodiment of the present invention is shown: a 10-35Kv electric anti-tipping smart handcart, including a frame 1 with load-bearing casters, a circuit breaker transfer compartment 11 is provided on the frame 1 via a lifting crank device 2, and a circuit breaker push-pull device 3 is also provided on the circuit breaker transfer compartment 11.

[0035] like Figure 2 and Figure 3 As shown, in a specific implementation, the lifting crank device 2 includes two sets of housings 201 arranged opposite each other on the frame 1. Each housing 201 has a rotary power unit 203 installed in it via a lifting adjustment unit 202. The lifting adjustment unit 202 includes a base 2021, a lifting arm 2022 mounted on the base 2021, and a mounting seat 2023 mounted on the lifting arm 2022. The rotary power unit 203 includes a power output shaft 2031, which is connected to the circuit breaker transfer chamber 11, and a torque sensor 2032 is also installed on the output shaft.

[0036] from Figure 3 As can be seen, the circuit breaker push-pull device 3 includes a circuit breaker handle 5 connecting unit 301, a left and right horizontal movement force unit 302, a front and rear push-pull power unit 303, and a quick-connect interface 304 for connecting the circuit breaker transfer compartment 11, arranged sequentially from front to back.

[0037] In this embodiment, the lifting crank device 2 allows the circuit breaker transfer compartment 11 to be adjusted in height and angle according to actual needs, adapting to switchgear of different heights and ground operation requirements under different working conditions.
