[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0023] Example 1
[0024] A gantry crane wind resistance testing device includes a jack support 2, a hydraulic jack 3, a pressure sensor 4, a pressure signal processor 5, and a computer 6. The hydraulic jack 3 is located in the groove 1 of the jack support 2 and is connected to a hydraulic pump station via a hydraulic oil pipe. The pressure sensor 4 is located between the hydraulic jack and the gantry crane A to be tested. The pressure sensor 4 is communicatively connected to the pressure signal processor 5, and the pressure signal processor 5 is communicatively connected to the computer 6.
[0025] The gate operator A under test is secured by windproof measures, while the fixed gate operator B is a rigidly fixed device that will not move with the wind. During use, the hydraulic jack 3 is placed in the slot 1 of the jack bracket 2, and the jack bracket 2 is placed between the legs of the gate operator A and the fixed gate operator B. The tail of the hydraulic jack 3 abuts against the leg of the fixed gate operator B, and the head of the hydraulic jack 3 presses the pressure sensor 4 against the leg of the gate operator A under test. The entire installation process is simple and quick, requiring no complicated tools or equipment, greatly shortening the test preparation time.
[0026] Start the hydraulic jack 3. The hydraulic jack 3 applies pressure to the door leg of the gate machine A to be tested through the pressure sensor 4. When the pressure exceeds the windproof measures of the gate machine A to be tested, the door leg of the gate machine A to be tested moves. The windproof effect of the windproof measures of the fan is evaluated by using this pressure.
[0027] During testing, pressure sensor 4 transmits signals to pressure signal processor 5. Pressure signal processor 5 processes the signals and then transmits them to computer 6. Pressure signal processor 5 is connected to computer 6 via a data cable, and computer 6's data acquisition software displays and processes the data in real time. This allows for real-time acquisition of the gantry crane's windproof performance data under various windproof modes. The data acquisition process is automated, requiring no manual intervention, greatly improving the accuracy and reliability of the test. The hydraulic jack 3 is connected to a hydraulic pump station via oil pipes. During testing, the operator only needs to operate the hydraulic pump station of hydraulic jack 3 and start the data acquisition software to complete the acquisition and recording of test data; the operation is simple and convenient.
[0028] After the test is completed, simply remove the hydraulic jack 3 from the jack support 2, and move the jack support 2 and other equipment away from the gantry crane A under test and the fixed gantry crane B to complete the disassembly of the test equipment. The disassembly process is simple and quick and will not cause damage to the gantry crane or dock facilities.
[0029] Example 2
[0030] Preferably, the jack support 2 is equipped with rollers at its bottom and a pull rod (not shown in the figure) on its upper part to facilitate movement. Furthermore, a handle is fixed to the end of the pull rod, allowing the entire jack support 2 to be pulled. In use, the hydraulic jack 3 is placed in the support groove 1, and the jack support 2 is dragged to the test position using the handle and pull rod.
[0031] Preferably, the bottom of the groove 1 is an arc-shaped structure, which matches the shape of the hydraulic jack 3 and provides stable and effective support for the hydraulic jack 3.
[0032] Example 3
[0033] Preferably, there are two of each of the jack support 2, hydraulic jack 3, and pressure sensor 4, which apply pressure to the two outriggers of the gate machine A to be tested respectively. There is one of each of the pressure signal processor 5 and computer 6. The signal from each pressure sensor 4 is processed by the pressure signal processor 5 and then transmitted to the computer 6. In this way, it is possible to detect whether the windproof measures at the two outriggers of the two gate machines meet the standards.
[0034] Preferably, the gantry crane wind resistance testing device also includes a workbench for placing the jack support 2, hydraulic jack 3, pressure sensor 4, pressure signal processor 5, and computer 6, making the overall structure of the gantry crane wind resistance testing device compact, easy to transport and store, and improving the portability of the equipment.
[0035] Preferably, the workbench is welded from steel plates. It is robust and durable, providing stable support for the testing equipment while also facilitating storage and organization, preventing damage during transportation and storage.
[0036] This embodiment features quick installation and easy disassembly.
[0037] During testing, simply connect two hydraulic jacks 3 to the pressure sensor 4 and place them on the jack support 2. Then, place the jack support 2 on the two side legs of the two gantry cranes to complete the installation of the testing equipment. The entire installation process is simple and quick, requiring no complicated tools or equipment, greatly shortening the test preparation time. The computer 6 (laptop) is connected to the pressure signal processor 5, which in turn is connected to the pressure sensor 4 via a data cable. Operation is convenient and requires no professional technicians for installation and debugging.
[0038] After testing, simply remove the hydraulic jack 3 from the jack support 2, and move the jack support 2 and other equipment away from the gantry crane to complete the disassembly of the testing equipment. The disassembly process is simple and quick, and will not damage the gantry crane or dock facilities. The integrated storage and testing workbench design allows for convenient storage and organization of the equipment after disassembly, facilitating future use.
[0039] This embodiment applies to both old and new gantry cranes and docks:
[0040] This testing method is designed for aging gantry cranes and wharves with inadequate wind protection facilities. It can effectively test the wind resistance performance of aging gantry cranes and wharves, providing a scientific basis for their renovation and upgrading. The testing equipment has a simple structure, is easy to assemble and disassemble, and is easy to operate. It can adapt to the complex environment and conditions of aging gantry cranes and wharves, ensuring their wind protection safety.
[0041] This testing method is applicable not only to older gantry cranes and wharves but also to newer ones. With port development and technological advancements, the wind resistance requirements for newer gantry cranes and wharves are becoming increasingly stringent. This testing method can meet the wind resistance testing needs of newer gantry cranes and wharves, ensuring their safe operation. The integrated design and automated data acquisition capabilities of the testing equipment adapt to the intelligent and automated development trends of newer gantry cranes and wharves, providing technical support for the modernization of ports.
[0042] This embodiment provides intuitive data analysis:
[0043] The collected data can be displayed and analyzed in real time on a laptop computer, allowing operators to intuitively understand the gantry crane's wind resistance performance. The data acquisition software boasts powerful data analysis capabilities, processing and analyzing the collected data to generate various charts and reports, providing a scientific basis for evaluating the gantry crane's wind resistance performance. Operators do not require specialized data analysis knowledge; they can easily complete data analysis and report generation using the data acquisition software, improving testing efficiency and accuracy.
[0044] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0045] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.
[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
