Description

Technical Field

[0001] This utility model relates to the field of power supply technology, specifically to a mobile power station. Background Technology

[0002] In the construction of long-distance pipelines, fully automated pipeline welding technology is the mainstream method. Automated welding equipment requires high stability and reliability of its power supply; currently, mobile power stations are mainly used to increase power output to meet the power requirements of fully automated welding.

[0003] In fully automated welding operations, the arc working time accounts for approximately 50% of the total weld construction time, while other tasks such as auxiliary grinding and lighting account for the remaining 50%. The mobile power station remains operational during non-arc welding hours. Idle operation during welding preparation wastes resources; simultaneously, to ensure stable power generation quality, the power output of existing mobile power stations is typically greater than actual needs, resulting in a significantly higher power load than the actual load during welding operations, again leading to resource waste. It primarily provides power to outdoor pipeline construction equipment and other electrical equipment. Existing mobile power stations typically consist of a high-horsepower engine that distributes power to generators, hydraulic pumps, etc., via a transfer case. To effectively address the technical challenges of collecting, storing, and reusing redundant electrical energy in tracked mobile power stations during pipeline construction, a new modular energy storage power source is being developed.

[0004] Some existing mobile power stations are mounted on tracked transport vehicles, making them suitable for various terrains. However, tracked transport vehicles are expensive. To reduce equipment investment costs, in some construction sites with slightly better conditions, mobile power stations are mounted on the rear of tractors. To improve the mobility of tractors carrying mobile power stations, they are generally not equipped with a trailer; instead, the mobile power station is fixed to a bracket at the rear of the tractor. However, because the battery packs of mobile power stations are quite heavy, when the mobile power station is heavy, the rear of the tractor is also heavy, making it prone to nose-lifting during movement, thus reducing safety. Utility Model Content

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figures 1-4 As shown, a mobile power station includes a tractor body 1. Suspension 2 is symmetrically installed on both sides of the rear end of the frame of the tractor body 1. The free ends of the two suspensions 2 are fixedly connected by a bracket 4. A hanging lug 3 is fixed to the rear end of the frame of the tractor body 1 between the two suspensions 2.

[0022] A support block 5 is fixed to the front end of the frame of the tractor body 1, and a front support plate 6 is fixed to the upper end of the support block 5. The front support plate 6 and the support block 5 are fixedly connected by bolts, and a front box 14 is fixed to the upper end of the front support plate 6.

[0023] A rear support plate 7 is provided on the rear side of the tractor body 1. A through hole 11 is provided at the front end of the rear support plate 7. A pin passes through the lug 3 and the through hole 11 at the front end of the rear support plate 7. The lower end of the rear support plate 7 contacts the upper end of the support rod 4. The rear box 15 is fixed to the upper end of the rear support plate 7.
