Description

Technical Field

[0001] This invention relates to the field of electrical control systems for engineering machinery, and in particular to an electrical control device and an aerial work platform using the electrical control device. Background Technology

[0002] Aerial work platforms are aerial work equipment that lifts workers and tools into the air to perform tasks. These platforms can be vehicle-mounted, self-propelled, or towed, and come in different lifting heights and working ranges. For example, self-propelled aerial work platforms have self-propelled capabilities and can be used within fixed areas, while vehicle-mounted aerial work platforms offer greater flexibility and mobility. 。

[0003] Aerial work trolleys are a type of aerial work platform, typically referring to a handcart that allows work at a high position. These trolleys may have lifting capabilities, enabling workers to push items to different heights for convenient high-altitude operations. They are commonly used in warehouses, construction sites, logistics centers, and other locations where goods need to be moved between different levels.

[0004] The existing aerial work platform trolley's electronic control system lacks a vehicle-wide control system, so the overall safety of the vehicle needs to be fully considered, and preventing tipping during lifting is of paramount importance to overall vehicle safety. Utility Model Content

[0005] This application provides an electronic control device that solves the problem in the prior art where aerial work platforms with outriggers, such as aerial handcarts, cannot control the outriggers before lifting due to the lack of a vehicle control system. This device achieves the goal of controlling the outriggers before lifting to improve the stability of the entire platform without the need for a vehicle control system.

[0006] This application discloses an electronic control device, including:

[0007] motor;

[0008] A relay, which is electrically connected to the motor;

[0009] Outrigger limit switch, wherein the outrigger limit switch is electrically connected to the relay;

[0010] An upper control handle, which is electrically connected to the relay;

[0011] An emergency stop switch, which is electrically connected to the relay via the upper control handle;

[0012] A key switch, which is electrically connected to the emergency stop switch.

[0013] Preferably, in this embodiment of the application, the number of the leg limit switches is the same as the number of legs.

[0014] Preferably, this application embodiment also discloses that the outrigger limit switch is connected to the indicator light one by one through the relay.

[0015] Preferably, this application embodiment also discloses that the upper control handle is connected to the lifting button.

[0016] This application discloses an aerial work platform, which uses the aforementioned electronic control device.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] 1. Because the same number of outrigger limit switches as the aerial work platform's outriggers are used, it is possible to prevent the vehicle from tipping over when it is being lifted, even without the installation of a vehicle control system, thus improving the safety of the vehicle at a lower cost.

[0019] 2. Because indicator lights are used that correspond one-to-one with the outrigger limit switches, operators can intuitively understand the status of each outrigger, which improves the operability of the aerial work platform. Attached Figure Description

[0026] This application provides an electronic control device that solves the problem in the prior art where aerial work platforms with outriggers, such as aerial handcarts, cannot control the outriggers before lifting because they lack a vehicle control system.

[0027] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0028] When the entire vehicle needs to be lifted, turn the key switch to activate the emergency stop switch and power on the vehicle. At this time, to ensure the stability of the vehicle, the vehicle cannot be lifted. This triggers the four outrigger limit switches, and the indicator lights corresponding to each outrigger will light up. Then, press the lift button using the upper control handle. The relays connected to the four outrigger limit switches will be energized, thereby powering the motor, and the entire vehicle will be lifted smoothly.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific embodiments. Example

[0030] Reference Appendix Figure 1-4 This application discloses an electronic control device, including: a motor 7; a relay 5 electrically connected to the motor 7; a leg limit switch 1 electrically connected to the relay 5; an upper control handle 4 electrically connected to the relay 5; an emergency stop switch 3 electrically connected to the relay 5 via the upper control handle 4; and a key switch 6 electrically connected to the emergency stop switch 3.

[0031] The number of outrigger limit switches 1 is the same as the number of outriggers, generally 4. The outrigger limit switches 1 are generally installed on the outriggers.

[0032] The outrigger limit switch 1 is connected to the indicator light 2 via the relay 5. The indicator light 2 is used to indicate to the operator that the outrigger has been extended into position.

[0033] The upper control handle 4 is connected to the lifting button.

[0034] Reference Appendix Figure 5 When the vehicle needs to be lifted, turn the key switch 6 to turn on the emergency stop switch 3 to power on the vehicle. At this time, in order to ensure the stability of the vehicle, the vehicle cannot be lifted. Manually pull the outriggers into place to trigger the outrigger limit switch 1. After the outrigger limit switch is triggered, the indicator lights 2 corresponding to each outrigger will light up. At this time, use the upper control handle 4 to press the lift button. The relay 5 connected to the outrigger limit switch 1 will be energized, thereby powering the motor 7, and the vehicle will be lifted smoothly.
