Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, and in particular to a live working safety protection device for an insulating bucket arm vehicle. Background Art

[0002] With the rapid development of my country's economic construction, the requirements for power supply reliability are higher. In recent years, the country has vigorously carried out live power repair and maintenance operations of the distribution network to avoid unnecessary interruptions to production and life. As an important tool for live operations, insulated boom trucks still need to increase exploration and develop new products with higher insulation safety solutions to meet the needs of safe operations in complex power operation scenarios.

[0003] During the use of the existing telescopic insulated boom truck, the effective insulating arm of the boom will be exposed due to dirt, moisture, rain, bumps and damage, which can easily reduce the insulation performance of the insulating arm. The actual measure is to support the bottom of the boom with a bracket and configure a soft rain cover on the outside of the boom for covering and protection, but there are the following problems:

[0004] 1. The existing soft rain cover needs to be installed and removed manually, which is time-consuming and laborious when using the vehicle. In addition, this situation will cause the soft rain cover to be often not used, so there is still a risk of reduced insulation performance of the boom;

[0005] 2. The soft rain cover after installation takes up too much space, and the dynamic rise and fall and rotation of the boom will also make the operation of the rain cover very complicated;

[0006] 3. The soft rain cover cannot be automatically opened, closed and folded as the arm moves, nor does it have the function of dehumidification and drying to improve the insulation effect.

[0007] Therefore, there is an urgent need for a live working safety protection device for an insulated boom truck to solve the above technical problems. Summary of the invention

[0008] The object of the present invention is to provide a live working safety protection device for an insulated boom vehicle, which can be automatically opened, closed and folded as the boom moves, and also has a dehumidification function, thereby improving the insulation effect.

[0009] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is specifically: a live working safety protection device for an insulated bucket arm vehicle, comprising a support frame arranged on the body of the insulated bucket arm vehicle, the vehicle body is provided with multiple metal arms, the front ends of the multiple metal arms are provided with insulating arms, the upper end of the support frame close to the metal arm is provided with a metal arm bracket, the metal arm bracket is provided with a metal arm proximity switch sensor, the upper end of the support frame close to the insulating arm is provided with a fixing frame, a support is provided on the upper side of the fixing frame, lower wing plates are hingedly provided on both sides of the support, a pressure rod is provided on the upper surface of the support for sliding up and down, the lower end of the pressure rod is in contact with the inner wall of the lower wing plate, a spring is connected between the outer wall of the lower wing plate and the upper side wall of the fixing frame, an electric motor is also provided on the outer side of the lower wing plate, and the electric motor output An upper wing plate is arranged on the shaft, a magnet plate is arranged on the outer side wall of the lower wing plate above the electric motor, a stress sheet sensor is arranged on the side of the magnet plate away from the lower wing plate, and upper wing plate proximity switch sensors are respectively arranged on both sides of the fixing frame; a controller and a dehumidifier are also arranged on the vehicle body, and the metal arm proximity switch sensor, the controller and the electric motor are electrically connected in sequence to form a control circuit for controlling the opening and closing of the electric motor; the metal arm proximity switch sensor, the stress sheet sensor, the controller, the electric motor and the dehumidifier are electrically connected in sequence to form a control circuit for controlling the electric motor to be turned off and the dehumidifier to be turned on respectively; the metal arm proximity switch sensor, the upper wing plate proximity switch sensor, the controller, the electric motor and the dehumidifier are electrically connected in sequence to form a control circuit for controlling the electric motor and the dehumidifier to be turned off.

[0011] Furthermore, a ventilation pipe is installed on the fixed frame, one end of the ventilation pipe is connected to the dehumidifier, and the other end is located between the two lower wing plates. The dehumidifier discharges dry gas into the closed wing plate through the ventilation pipe, so that the dry gas can improve the effective insulation section performance of the insulating arm.
