In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0023] like Figure 1 As shown, this embodiment provides a method for debugging a monorail crane platform. The method comprises the following steps:

[0024] S1. During the assembly superstructure stage, the monorail is hoisted to the superstructure for installation.

[0025] Specifically, the monorail crane includes a body 1, two synchronous drive motors 2, two gear drivers 3, a guide rail 4, two limiters 5, a power supply 6, a command line 7, a cable guide 8 and two lifting mechanisms 9. It can be understood that the monorail crane also includes many structures such as an overload limit switch, which are not described here one by one. The guide rail 4 is used to be fixed to the superstructure, and the two limiters 5 are respectively arranged at both ends of the guide rail 4; the two gear drivers 3 are fixedly connected to the body 1, and the two gear drivers 3 are slidably connected to the guide rail 4 at the same time, and the body 1 is slidably connected to the guide rail 4 through the gear driver 3.

[0026] The power of the two driving motors 2 is supplied by a power supply 6. The two driving motors 2 are connected to the two gear drivers 3 one by one. The two driving motors 2 are used to drive the two gear drivers 3 to move along the guide rail 4 respectively. At this time, the two gear drivers 3 drive the main body 1 to move along the guide rail 4. When the main body 1 touches the limiter 5 at the end of the guide rail 4, it stops moving.

[0027] In this embodiment, both driving motors 2 are connected with a command wire 7, which is used to transmit control instructions to the driving motor 2 so as to control the movement of the driving motor 2. In order to store the command wire 7, the command wire 7 is wound around a cable guide 8. When the driving motor 2 moves along the guide rail 4, the cable guide 8 will retract and release the command wire 7 according to the working conditions, thereby preventing the command wire 7 from being entangled.

[0028] The two lifting mechanisms 9 are both arranged on the main body 1 , one lifting mechanism 9 is used to lift the load on the left side of the main body 1 , and the other lifting mechanism 9 is used to lift the load on the right side of the main body 1 .

[0029] When installing a monorail crane, use a gantry crane or a crane to lift the monorail crane and lift the monorail crane to a preset installation height. Then, position the two ends of the monorail crane first, that is, use a temporary support structure to support the two ends of the monorail crane. The position of the monorail crane can be adjusted through the temporary support structure. After the position adjustment is completed, the guide rail 4 of the monorail crane is welded and fixed to the cross support structure in the superstructure.

[0030] S2. Build a structural platform and lift the superstructure onto the structural platform for fixation.

[0031] Specifically, the structural platform includes support legs 10, angle steels 11 and I-beams 12. First, the required materials are cut and blanked, then a suitable assembly site is selected, and the support legs 10 are positioned. Then, the I-beams 12 are lifted to a suitable position on the support legs 10 by a crane for welding and fixing. At the same time, the angle steels 11 are welded and fixed to the I-beams 12 according to the drawings. The overall assembly of the structural platform is completed by such operations. Among them, the size of the structural platform can be determined according to the specifications of the superstructure of the ship to be built. The number of support legs 10, angle steels 11 and I-beams 12 is determined according to actual conditions. In this embodiment, the construction height of the structural platform is greater than 2m.

[0032] After the construction of the structural platform is completed, the bracket 13 is installed on the surface of the structural platform, and the superstructure is hoisted to the structural platform using a gantry crane so that the bracket 13 supports the bottom of the superstructure, and then the bracket 13 and the structural platform, and the bracket 13 and the superstructure are welded and fixed to ensure that the superstructure is supported stably and firmly. The size of the bracket 13 can be determined according to the actual seat width of the superstructure.

[0033] S3. Power on the monorail crane and check the operating environment of the monorail crane.

[0034] Specifically, the power supply 6 includes a 440V power supply 6 control box and a 220V lighting power supply 6. The drive motor 2 is connected to the 440V power supply 6 control box. The 220V lighting power supply 6 is used to power the running lights of the monorail crane. After the wiring is completed, check whether the wiring is correct.

[0035] The operation of the monorail crane of this embodiment can be controlled by a wireless remote controller and a wired controller. When starting the monorail crane, it is necessary to check whether the emergency stop button on the wireless remote controller and the wired controller is in the reset position to ensure that the electrical working circuit of the monorail crane traction motor is normal. Then close the switch and turn on the power to confirm whether the driving indicator light on the monorail crane is on. If it is on, it means that the line is normal.

[0036] Checking the operating environment of the monorail crane includes: checking and confirming whether the moving parts in the monorail crane are injected with lubricating grease, for example, the moving parts are gears that transmit power in the gear driver 3. The inspection can ensure that the moving parts in the monorail crane are not easy to wear. In addition, visually check whether there are obstacles and blocks on the monorail crane's travel route, so as to ensure the safety of the monorail crane's operation.

[0037] S4. Carry out monorail crane function debugging test.

[0038] Specifically, by operating the travel switch on the wired remote controller, the lifting, lowering, and rotating motion tests are performed without load. Then, the wireless remote controller is used to remotely control the monorail crane without load to perform lifting, lowering, and rotating motion tests. Such operations can confirm whether the wireless remote controller and the wired controller can accurately control the monorail crane.

[0039] When the monorail crane is in operation, the command line 7 will change. At this time, the retraction and release of the cable guide drum 8 is checked synchronously to detect whether the cable guide drum 8 can retract and release the command line 7 in time.

[0040] Check whether the limiter 5 is working properly to test the monorail crane's running stroke. First, control the monorail crane to extend to the left and right. When the monorail crane presses the limiter 5 during the running process, the monorail crane should automatically stop running and the driving indicator light will go out.

[0041] Check whether the static load test meets the requirements. Use a shore crane (truck crane) to load a weight on the hook of the monorail crane. The weight of the weight should be 1.25 times the rated lifting weight. Keep it stationary for 10 minutes. Visually check whether the distance between the load and the ground has changed. If the load visually decreases, it means that the overload limit switch set on the monorail crane does not meet the setting requirements. At this time, the overload limit switch needs to be readjusted until the monorail crane meets the static load test requirements.

[0042] Check the reliability of the monorail crane's own brakes. Use a shore crane (truck crane) to load 1.1 times the rated lifting weight, and use the two operating speeds set by the manufacturer's standard to make the loaded load perform lowering and lifting tests. At the same time, use a wireless remote control to perform two braking tests during the lowering and lifting process.

[0043] Carry out rated working load test. Use a shore crane (truck crane) to load the monorail crane to the safe rated lifting weight, and use a wireless remote control to perform lifting, lowering, and slewing motion tests twice each. During this period, check whether there is any abnormal parking state. If there is an abnormal parking phenomenon, it means that the overload limit switch does not meet the setting requirements. At the same time, during the test, it is necessary to record the hook lifting speed and slewing speed, and check whether the recorded data meets the manufacturer's set requirements.

[0044] Carry out the safety test of the monorail crane. Manually press the overload limit switch, and the crane cannot lift 1.1 times the rated load. Simultaneously visually check whether the lifting weight has dropped. If the lifting weight drops, it means that there is a problem with the brake function of the monorail crane.

[0045] Use the height of the structural platform to test the hook release on the left and right sides. When lowering the hook, check whether the wire rope of the lifting mechanism 9 is wound. If winding occurs, adjust the wire rope winding in time until the hook is lowered without the above phenomenon.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
