Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ocean engineering, in particular to a portable measuring device for measuring the weight and gravity center of wheeled equipment. BACKGROUND

[0002] Ocean engineering refers to a new, reconstruction, or expansion project whose main body is located on the sea side of the coastline for the purpose of developing, utilizing, protecting, and restoring marine resources. Currently, in the field of ocean engineering, large ships are often used to transport goods to the sea, and during the transportation process, the goods often need to be lifted.

[0003] During the lifting of heavy equipment, determining the weight and gravity center position of the object is of great importance, especially in application scenarios involving safety requirements. Since the weight and gravity center position of the object directly affect the stability and safety of the lifting operation, in order to prevent the object from tilting, overturning, or accidentally rotating during lifting, or to accurately adjust the object to the desired specific angle, the appropriate lifting point must be selected based on the gravity center position of the object to ensure the balance and stability of the object during lifting and reduce the risk of accidents.

[0004] However, during ocean transportation, measuring the gravity center of a large weight object faces great challenges. Due to the inevitable influence of sea waves on the ship during navigation, the ship body will sway, tilt, and other unstable states. This dynamic environment makes it difficult to ensure the accuracy of gravity center measurement, and the measuring instrument is easily disturbed by the movement of the ship body, resulting in errors. In addition, due to the limited space on the ship, the methods that can be used to measure the gravity center of a large weight object on an ocean-going ship are also greatly limited. Therefore, it is particularly necessary to develop a measuring system that can accurately and quickly calculate the gravity center position and weight of wheeled equipment during navigation and can be operated in limited working space such as ships. Such a system not only helps to improve the safety of lifting operations during ocean transportation, but also ensures the efficiency and accuracy of offshore operations. Therefore, we propose a portable measuring device for measuring the weight and gravity center of wheeled equipment to effectively solve the above problems. SUMMARY

The weighing sensor 103 and the inclination sensor 104 are both provided with a built-in Bluetooth module, and they can convert the detection signals into Bluetooth signals and transmit them to the controller 200.

[0037] Further, distance measuring sensors 106 are arranged on the four side walls of the measuring seat 100, the distance measuring sensors 106 adopt laser sensors, and the signal output ends of the distance measuring sensors 106 are in communication connection with the controller 200.

Through accurate distance measurement, the system can adjust the calculation in a dynamic environment to ensure that the calculation of the center of gravity position of the object is more accurate.

[0038] It is worth mentioning that a handle 107 is arranged on one side of the measuring seat 100, and an anti-skid pad 108 is arranged on the bottom surface of the measuring seat 100. Among them, the handle 107 is arranged to facilitate carrying the measuring seat 100, and the guide slope 101 is hingedly arranged on the measuring seat 100, which is foldable to reduce the storage volume and further facilitate carrying.

That is, the number of guide columns 300 is four, and the bearing table 102 can slide along the axial direction of the guide column 300. In addition, it is worth mentioning that when the bearing table 102 is subjected to a downward pressure of 10N, the bearing table 102 is just in contact with the load sensor 103. Specifically, when calculating the downward pressure of each wheel, the measured result of the corresponding load sensor 103 is added by 10N.

[0040] In the specific application process of the embodiment, first, the number of measuring seats 100 can be selected according to the number of wheels of the equipment to be measured, then each measuring seat 100 is placed in front of the corresponding wheel, and finally the driving mechanism is driven to drive the equipment to be measured to move forward, so that each wheel is just placed on the bearing table 102. In the detection process, the load sensor 103 and the inclination sensor 104 are arranged in each measuring seat 100, and the distance measuring sensor 106 is arranged outside the measuring seat 100. The above three sensors transmit the measurement signals to the controller 200, and the controller 200 calculates the weight and center of gravity of the equipment to be measured according to the internal algorithm.

[0041] Embodiment two: please refer to Figure 1 Figure 5 and Figure 9 In the embodiment, the top surface of the measuring seat 100 and located at the left and right sides of the bearing table 102 are provided with strip-shaped through holes 110, the strip-shaped through holes 110 are movably provided with blocking blocks 400, the bottom of the blocking block 400 is vertically slidably provided with a supporting column 401, and the supporting column 401 is fixedly connected with the inner bottom surface of the measuring seat 100, that is, the blocking block 400 can be lifted up and down. In addition, the top of the blocking block 400 is wedge-shaped, and the side of the top of the blocking block 400 facing the bearing table 102 is a slope.

[0042] ​Further, the inside of the measuring seat 100 and the left and right sides of the bearing table 102 are each provided with a mounting column 500, and the two mounting columns 500 are located between the two blocking blocks 400. The surface of the mounting column 500 is rotatably provided with a first gear 501 and a second gear 502, the first gear 501 and the second gear 502 are engaged, and the surface of the mounting column 500 is also rotatably provided with a third gear 503, and the third gear 503 and the second gear 502 are coaxially connected. The left and right sides of the bearing table 102 are each provided with a first rack 111, and the surface of the blocking block 400 is provided with a second rack 402. The first gear 501 and the first rack 111 are engaged, and the third gear 503 and the second rack 402 are engaged. The radii of the first gear 501 and the second gear 502 are consistent, and the radius of the second gear 502 is half of the radius of the third gear 503. In the natural state, the top surface of the bearing table 102 is flush with the top surface of the measuring seat 100, and the top surface of the blocking block 400 is not higher than the top surface of the measuring seat 100. When the bearing table 102 is lowered to abut against the weighing sensor 103, the blocking block 400 will move upward, and the moving distance of the blocking block 400 is twice the moving distance of the bearing table 102. The blocking block 400 is used to block the front and rear sides of the wheel, so as to ensure that the wheel is always located on the bearing table 102.

[0043] It is worth mentioning that the first gear 501 and the third gear 503 are connected through the same rotating shaft, and the rotating shaft is rotatably connected with the mounting column 500. The second gear 502 is rotatably connected with the surface of the mounting column 500 through another rotating shaft.

[0044] In the embodiment, when the wheel of the equipment to be measured rolls along the guide slope 101 to the top surface of the measuring seat 100, in the initial state, the blocking block 400 is retracted into the strip-shaped through hole 110 to avoid hindering the wheel from advancing. When the wheel passes through the strip-shaped through hole 110 on one side and rolls onto the bearing table 102, under the action of gravity, the bearing table 102 is lowered, and the blocking blocks 400 on the two sides are raised to block the front and rear sides of the wheel, so as to ensure that the position of the wheel is always on the bearing table 102.

[0045] Embodiment three: please refer to Figure 1 - Figure 10In the embodiment, the top surface of the bearing table 102 is provided with an embedded groove 112 on both front and back sides, a main shaft 113 is rotatably arranged in the embedded groove 112 and close to the center of the bearing table 102, and a turnover plate 114 is fixedly arranged on the outer part of the main shaft 113. A driven gear 115 is fixedly arranged on the outer part of the main shaft 113, a third rack 116 is slidably arranged on the inner bottom surface of the embedded groove 112, the third rack 116 is engaged with the driven gear 115, one end of the embedded groove 112 is provided with an electromagnet 117, and a magnet 118 is embedded in the end of the third rack 116 close to the electromagnet 117; when the electromagnet 117 is powered off, the third rack 116 is attached to the electromagnet 117, and the turnover plate 114 is in a horizontal posture; when the electromagnet 117 is powered on, the same magnetic poles of the electromagnet 117 and the magnet 118 face each other, that is, under the repulsion, the third rack 116 is pushed away from the electromagnet 117, thereby indirectly driving the turnover plate 114 to rotate, and under the action of the two turnover plates 114, the wheels are clamped together.

[0046] Further, the electromagnet 117 is electrically connected with the power supply 105, two conductive contacts 119 are respectively connected with two leads of the electromagnet 117, the two conductive contacts 119 are respectively arranged on the inner top surfaces of the two guide grooves 109, two conductive sheets 120 are respectively connected with the positive and negative poles of the power supply 105, the two conductive sheets 120 are respectively arranged on the top ends of the two guide columns 300, and the bearing table 102 and the guide column 300 are made of insulating materials; when the bearing table 102 abuts against the weighing sensor 103, the conductive contacts 119 are in contact with the corresponding conductive sheets 120. Since the number of the guide columns 300 and the number of the guide grooves 109 are both four, each electromagnet 117 can correspond to two guide grooves 109, and the four conductive contacts 119 are respectively located in the four guide grooves 109; the number of the conductive sheets 120 is also four, of which two conductive sheets 120 are connected with the positive pole of the power supply 105, and the other two conductive sheets 120 are connected with the negative pole of the power supply 105; when the bearing table 102 abuts against the weighing sensor 103, the two electromagnets 117 are powered on.

[0047] It is worth mentioning that the conductive contacts 119 and the conductive sheets 120 are made of red copper, and the conductive sheets 120 are arched and have a certain toughness, which facilitates the sufficient contact between the conductive contacts 119 and the conductive sheets 120.

[0048] In the embodiment, when the wheels move to the bearing table 102, under the action of gravity, the bearing table 102 is lowered to abut against the weighing sensor 103, at this time, the two electromagnets 117 are powered on, and the two turnover plates 114 are rotated towards each other, thereby clamping the wheels. In this way, under the condition of sea water shaking, the measuring seat 100 can always “hold” the wheels, avoiding the relative position between the measuring seat 100 and the wheels from being deviated or misaligned, which is conducive to improving the measurement accuracy.

[0049] It has to be noted that, in the present document, the terms "first", "second", etc. merely serve to identify a subject or action, and do not necessarily require or imply any such actual relationship or order between such subjects or actions.
