Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, specifically a gantry crane that provides power supply and communication in harsh environments. Background Technology

[0002] With the large-scale development of the Internet of Things in China, the supporting gantry crane material handling industry has emerged rapidly. Traditional gantry cranes use cable traction trolleys or drag chains for loading, unloading, and placement. This type of power supply is limited by cold outdoor climates and salt spray environments, making it impossible to operate at heights or in vertical and horizontal spaces, resulting in low lifting efficiency and excessively long loading and unloading times and high costs. There is an urgent need to develop a new power supply system to match it. At the same time, existing gantry cranes lack devices to monitor the levelness of the sliding contact line, so when the sliding contact line tilts or loses levelness, there is no timely alarm reminder, which affects the operational safety of the gantry crane. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a gantry crane with power supply and communication in harsh environments. By setting up data lines, waveguides, sliding contact lines, current collectors, copper conductors, wires, and conductive copper sliders, the power supply of the gantry crane during operation is achieved through the sliding contact connection between the copper conductors in the sliding contact lines and the conductive copper sliders on the current collectors. This power supply method is not limited by outdoor cold climates and salt spray environments, ensuring the safe operation of the gantry crane and effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gantry crane for power supply and communication in harsh environments, comprising two support frames, a horizontal plate installed between the upper ends of the two support frames, a horizontal bar installed on the lower side of the horizontal plate, a locking seat fixedly installed on the horizontal bar, a data cable connected to the locking seat, a waveguide installed on the top side of the data cable, an antenna installed on the lower side of the waveguide, three sliding contact lines installed on one side of the data cable, a copper guide strip installed on the inner side of the sliding contact line, a conductive copper slider installed on the lower side of the copper guide strip, a current collector connected to the lower side of the antenna and the conductive copper slider, and laser rangefinders installed at equal intervals on the horizontal plate, the laser rangefinders being respectively positioned directly above the data cable and the three sliding contact lines.

[0005] Furthermore, tensioners are connected between the two ends of the sliding contact line and the data line and the support frame, and a gantry is provided on the lower side of the support frame.

[0006] Furthermore, a trolley module is provided on the side of the gantry, and a container spreader is connected to the trolley module via steel cables.

[0007] Furthermore, a movable base is provided at the lower end of the gantry, and a cable is connected to the lower side of the current collector.

[0008] Furthermore, a mounting bracket is fixedly installed on the lower side of the current collector, and the current collector and the mounting bracket are connected by bolts.

[0009] Furthermore, the crossbar is bolted to the support frame, and the cross plate is bolted to the support frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of data lines, waveguides, sliding contact lines, current collectors, copper conductors, wires, and conductive copper sliders, enables the gantry crane to be powered during operation by sliding contact between the copper conductors in the sliding contact lines and the conductive copper sliders on the current collectors. This power supply method is not limited by outdoor cold climates and salt spray environments, ensuring the safe operation of the gantry crane.

[0011] 2. This utility model, through the setting of a horizontal plate and a laser rangefinder, enables the laser rangefinder to accurately measure the height difference between the horizontal plate and the data line and the sliding contact line. When the height difference changes, it indicates that the overall levelness of the data line and the sliding contact line has changed. The laser rangefinder can then monitor and alarm in a timely manner, thereby ensuring the safe operation of the gantry crane. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This embodiment provides a technical solution: a gantry crane for power supply and communication in harsh environments, including two support frames 5, a horizontal plate 7 installed between the upper ends of the two support frames 5, a horizontal bar 6 installed on the lower side of the horizontal plate 7, a locking seat 11 fixedly installed on the horizontal bar 6, a data cable 12 connected to the locking seat 11, a waveguide 17 installed on the top side of the data cable 12, an antenna 16 installed on the lower side of the waveguide 17, three sliding contact lines 9 installed on one side of the data cable 12, copper guide strips 19 installed inside the sliding contact lines 9, conductive copper sliders 18 installed on the lower side of the copper guide strips 19, a current collector 14 connected to the lower side of the antenna 16 and the conductive copper sliders 18, and laser rangefinders 8 installed at equal intervals on the horizontal plate 7, the laser rangefinders 8 being respectively positioned directly above the data cable 12 and the three sliding contact lines 9.

[0016] like Figure 1-5 As shown, during operation, the gantry 1 moves via the movable base 2. The trolley module 3 on the gantry 1 can drive the container spreader 4 to move laterally. When the trolley module 3 moves, it transmits signals without contact through the antenna 16 on the current collector 14 and the waveguide 17 inside the data cable 12. The conductive copper slider 18 on the current collector 14 slides into contact with the copper conductor 19 on the sliding contact line 9, ensuring the power supply stability of the gantry crane during the sliding connection process. This is not limited by harsh environments (high temperature, low temperature, outdoor wind and snow, etc.), which can reduce the use of cables, reduce the risk of cable breakage, reduce maintenance costs, and extend the lifespan of the crane. With a long service life, it can also transmit data and video signals to the ground center, providing a feasible basis for realizing intelligent solutions. It can operate in all directions.

[0022] The working principle of the gantry crane with power supply and communication in harsh environments provided by this utility model is as follows: Figures 1-5 As shown, during operation, the gantry 1 moves via the movable base 2. The trolley module 3 on the gantry 1 can drive the container spreader 4 to move laterally. When the trolley module 3 moves, it transmits signals without contact through the antenna 16 on the current collector 14 and the waveguide 17 inside the data cable 12. The conductive copper slider 18 on the current collector 14 slides into contact with the copper conductor 19 on the sliding contact line 9, ensuring the power supply stability of the gantry crane during the sliding connection process. This is not limited by harsh environments (high temperature, low temperature, outdoor wind and snow, etc.), which can reduce the use of cables, reduce the risk of cable breakage, reduce maintenance costs, and extend the lifespan of the crane. With a long service life, it can also transmit data and video signals to the ground center, providing a feasible basis for realizing intelligent solutions. It can operate in all directions.
