Description

Technical Field

[0001] This utility model relates to the field of engineering equipment technology, and in particular to a beam-mounted mobile trolley driven by battery power. Background Technology

[0002] A beam-mounted mobile trolley is a piece of equipment used in bridge construction, mainly for transporting and moving large prefabricated components, such as prefabricated beams, during the bridge construction process. Prefabricated beams are a building construction technology that refers to beams prefabricated in a factory or a specialized prefabrication plant.

[0003] There are many types of existing beam-mounted mobile trolleys, including cable-powered trolleys and sliding contact line-powered trolleys. Cable-powered trolleys have the following drawbacks: a) Because the trolley is powered by a cable, multiple workstations need to be set up on the entire production line for power supply, which not only increases project costs but also slows down project construction; b) The cables on cable-powered trolleys are very long and exposed at the bottom, posing a tripping hazard to workers; c) When the cable-powered trolley is moving, the long cables can easily become entangled in other equipment on site, potentially damaging it; d) The cables can easily become entangled in exposed bolts, studs, reinforcing bars, and other on-site facilities, causing damage to the cable sheath and posing a risk of cable failure with long-term use.

[0004] The following defects exist in sliding contact line powered trolleys: a) The sliding contact line current collector is at risk of being damaged when changing production lines; b) The spring synchronizer of the sliding contact line current collector is at risk of deformation under long-term operation. Spring deformation will cause the current collector to fail to reset, and long-term use will lead to damage to the current collector and power failure. Utility Model Content

The rechargeable battery 3 is electrically connected to the corresponding drive motor 5 through the driver 6.

[0036] The chassis of this utility model is assembled from prefabricated car bodies, which reduces the manufacturing difficulty of large chassis, facilitates transportation, and when the chassis is damaged, only one or a few prefabricated car bodies need to be replaced, without replacing the entire chassis. This results in high workpiece utilization and reduces equipment maintenance costs.

[0037] In some embodiments, refer to Figure 1 and Figure 2 Each of the drive mechanisms further includes a reducer 7, and the drive motor 5 is connected to the corresponding drive wheel 4 through the reducer 7.

[0038] In some embodiments, the beam-mounted mobile trolley further includes a mobile charging trolley, which comprises a charging power supply and a trolley. The charging power supply is connected to a charging cable adapted to the charging port 2, and the charging power supply is mounted on the trolley. Each time charging is required, the mobile charging trolley can be pushed next to the beam-mounted mobile trolley, and the charging cable on the charging power supply can be plugged into the charging port 2 to charge the rechargeable battery 3.

[0046] Compared to existing cable-powered trolleys, this utility model adds a rechargeable battery 3 to the frame, which powers the beam-mounted mobile trolley. This eliminates the need for cables on the beam-mounted mobile trolley, preventing accidents such as workers tripping over excessively long cables or other equipment being damaged when the beam-mounted mobile trolley moves.

[0047] Furthermore, since this utility model uses a rechargeable battery 3 for direct power supply, compared to cable-powered trolleys, it eliminates the need for multiple charging stations, thereby reducing project costs and improving project construction progress and efficiency.

[0048] Compared to existing sliding contact line powered trolleys, this utility model uses a rechargeable battery 3 for direct power supply, eliminating the need for a sliding contact line current collector. This prevents accidents such as damage to the sliding contact line current collector during production line changes and eliminates the need to consider the deformation of the springs on the sliding contact line current collector.
