Description

Technical Field

[0001] The utility model relates to the technical field of backup power supplies, in particular to a portable backup power supply. Background Art

[0002] The ETC gantry system is a facility used for non-stop toll collection on highways. It has functions such as segmented billing for passing vehicles, traffic surveys, video monitoring, and speeding screening. After a car passes through the gantry, the monitoring system installed on the gantry will automatically identify the car and collect the fees. The various cameras and lamps on the ETC gantry are usually centrally controlled by a cabinet located on one side of the gantry. When the ETC gantry system cannot continue to work due to a power supply line failure, highway maintenance personnel can use a movable backup power supply to power the ETC gantry cabinet.

[0003] Since the ETC gantry system has high working intensity and high power consumption, small diesel generator sets are often used for temporary power supply. However, most of the commonly used small diesel generators do not have the function of mobility and have poor portability. Some small diesel generators have improved the portability of the generator by installing casters at the bottom of the frame. However, due to the small contact area between the casters and the ground, the overall stability of the equipment is poor when the diesel engine is running, which needs to be improved.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0019] By adopting the above-mentioned scheme, when the portable backup power supply needs to be moved, the utility model only needs to rotate the first worm 10 through the hand wheel 11 to utilize the transmission mechanism to drive the two first rotating shafts 5 to rotate, thereby driving the wheel frame 7 to rotate, so that each roller 8 is in contact with the ground, and gradually lifts up the frame 1, so that the frame 1 is completely separated from the ground. At this time, the portable backup power supply can be easily moved by the roller 8. After the portable backup power supply is moved to the desired position, it is only necessary to rotate the hand wheel 11 in the opposite direction to retract the roller 8 into the inner side of the frame 1 and make the frame 1 stably contact with the ground, thereby ensuring the stability of the device when the diesel generator set 3 is running, and the operation is simple and convenient.

[0020] Specific combination Figure 1 , Figure 3 In one embodiment of the utility model, both ends of the first rotating shaft 5 are rotatably connected to the frame 1 through the bearing seat 6 to ensure the stability of the rotation of the first rotating shaft 5 on the frame 1 and to enable a stable connection between the two.

The outer wall of the first rotating shaft 5 is fixedly sleeved with a second worm gear 9, and the second worm gear 9 is meshed with the corresponding second worm 15.

[0022] Through the cooperation of the first worm gear 14 and the first worm 10, the second rotating shaft 13 can be driven to rotate by simply turning the hand wheel 11, and then the two first rotating shafts 5 can be driven to rotate by utilizing the cooperation of the second worm gear 9 and the second worm 15 to retract and extend each roller 8 on the frame 1. The operation is simple and convenient, and the two-stage reduction transmission can make the operation more labor-saving.

[0023] Specific combination Figure 2 On the basis of the previous embodiment, further, the spiral directions of the two second worm gears 9 are opposite, thereby ensuring that when the second rotating shaft 13 rotates, it can drive the two first rotating shafts 5 to rotate in the opposite direction at the same time, so that the wheel frames 7 symmetrically distributed on the inner side of the frame 1 can move in the opposite direction at the same time.

[0024] Specific combination Figure 1 In one embodiment of the utility model, a U-shaped pull rod 16 is arranged above the frame 1, and both ends of the U-shaped pull rod 16 are rotatably connected to the top of the frame 1 through a hinge seat 17.
