Description

Technical Field

[0001] This utility model relates to the field of air valve maintenance technology, and in particular to an air valve maintenance device. Background Technology

[0002] In many fields such as industrial production and building ventilation, air dampers are key devices for controlling airflow, and their normal operation plays a vital role in the stability and efficiency of the entire system. However, as air dampers are used for longer periods, various malfunctions and damages inevitably occur, necessitating regular inspection and maintenance to ensure their continuous and reliable operation.

[0003] In practice, the installation height of air valves varies, posing a significant challenge to maintenance. Traditional maintenance methods often require personnel to use additional climbing equipment, such as ladders and scaffolding, or to undertake cumbersome on-site setup work to reach the appropriate height for maintenance. This approach is not only time-consuming and labor-intensive, increasing the workload of maintenance personnel, but also raises concerns about the stability of the climbing equipment, posing certain safety hazards.

[0004] Most existing valve maintenance devices lack effective positioning mechanisms, making precise clamping and positioning of the valves impossible. During maintenance, the valves are prone to shaking due to external factors or operator actions, which not only complicates maintenance but may also lead to incomplete repairs or secondary damage, thus affecting the quality of maintenance and subsequent performance. Furthermore, current valve maintenance devices are significantly inadequate in terms of safety protection; many lack effective protective measures, resulting in poor safety. Therefore, a new valve maintenance device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a valve maintenance device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A valve maintenance device includes a base, on the upper end of which a first electric telescopic rod is fixedly installed. The telescopic end of the first electric telescopic rod faces upward and is fixedly connected to a maintenance platform. A fence is fixedly connected to the upper end of the maintenance platform. A positioning mechanism is provided on the front side wall of the fence. The positioning mechanism is used to clamp and position the valve.

[0007] As a further improvement of this utility model, the positioning mechanism includes a sleeve plate fixedly connected to the side wall of the fence. A movable plate is slidably inserted inside the sleeve plate. A mounting frame is fixedly connected to the upper end of the movable plate. Clamping members are provided on the opposite side walls of the mounting frame. The clamping members include a third electric telescopic rod fixedly installed on the side wall of the mounting frame. The telescopic end of the third electric telescopic rod passes through the mounting frame and is fixedly connected to a clamping plate. A second electric telescopic rod is fixedly installed at the upper end of the sleeve plate. The telescopic end of the second electric telescopic rod passes through the upper end of the sleeve plate and contacts the movable plate.

[0008] As a further improvement of this utility model, casters are installed at the four corners of the lower end of the base.

[0009] As a further improvement of this utility model, an opening and closing door is hinged to the side wall of the fence, and a connecting block is fixedly connected to the upper end of the opening and closing door. A connecting bolt is provided through the upper end of the connecting block, and the connecting bolt is screwed to the fence.

[0010] As a further improvement of this utility model, a ladder is fixedly connected to the upper end of the base.

[0011] As a further improvement of this utility model, four guide telescopic rods are fixedly installed on the upper end of the base, and the telescopic ends of the guide telescopic rods are fixedly connected to the lower end of the inspection platform.

[0012] The beneficial effects of this utility model are: The first electric telescopic pole allows for flexible adjustment of the maintenance platform height. Maintenance personnel can precisely control the extension and retraction of the first electric telescopic pole according to the air valves installed at different heights, so that the maintenance platform can quickly reach the appropriate height, thus facilitating the maintenance of the air valves without the need for additional climbing equipment or cumbersome on-site setup work.

[0013] The positioning mechanism, through the coordinated operation of the sleeve plate, movable plate, mounting bracket and clamping components, can achieve precise clamping and positioning of the air valve. The air valve to be repaired is placed between the two clamping plates, and the two third electric telescopic rods are activated to extend synchronously, which can drive the two clamping plates to move synchronously, firmly clamping the air valve, ensuring the stability of the air valve during the repair process, and preventing the repair quality from being affected by the air valve shaking.
