[0002] New sensor technologies for cranes have been a key development trend in the crane industry in recent years. These technologies aim to improve the efficiency, safety, and reliability of lifting operations by integrating advanced sensors and intelligent control technologies. These sensors monitor various crane operating parameters, such as boom angle, extension length, and load weight, in real time. Through data analysis, they optimize operational processes and reduce the risk of human error and accidents.

[0003] Crane angle sensors are a crucial component of crane machinery, primarily used to measure the length and angle of a crane's telescopic boom to ensure the safety and accuracy of lifting operations. The operating principle of these sensors involves a variety of sensor technologies, including but not limited to angle sensors and inclination sensors. For example, angular displacement sensors employ a non-contact design, measuring angular changes through specific principles (such as resistance changes, capacitance changes, and magnetoresistance).

[0022] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example 1:

[0024] See also Figure 1 - Figure 4, a new type of crane sensor of this embodiment includes a base 1 and a shell 2, the shell 2 is plug-in connected to the inside of the base 1, the outside of the shell 2 is fixedly connected with a fixed ring 4, the fixed ring 4 is in contact with the top surface of the base 1, and a movable ring 5 is provided on the top of the fixed ring 4, which is rotatably connected to the outside of the shell 2, and two handles 3 are hingedly connected at both ends of the movable ring 5. The bottom of the movable ring 5 is fixedly connected with a plurality of movable rods 9, and the bottom of the movable rod 9 is movably connected to the inside of the fixed ring 4. A plurality of slide grooves 8 are machined inside the base 1, and a plurality of sliders 6 are fixedly connected around the bottom of the shell 2. The plurality of sliders 6 are movably connected to the inside of the slide groove 8 respectively. The bottom of the movable rod 9 passes through the top of the base 1, and the bottom of the movable rod 9 is plug-in connected to the inside of the slider 6. A notch 7 is machined at one end of the slide groove 8, and the slider 6 is movably connected to the inside of the notch 7, and the notch 7 is communicated with the inside of the slide groove 8;

[0025] The base 1 is fixed to the middle part of the crane boom by bolts. When the interior of the housing 2 needs to be opened for inspection, the two handles 3 are flipped upwards, and then the two handles 3 are held by two hands and moved upwards. The handles 3 will drive the movable ring 5 to move upwards, and the movable ring 5 will drive the movable rod 9 to move upwards, so that the bottom of the movable rod 9 is separated from the interior of the slider 6. At the same time, the bottom of the movable rod 9 is separated from the interior of the base 1. The housing 2 is rotated by the handles 3, so that the housing 2 drives the fixed ring 4 to rotate, and at the same time, the housing 2 drives the slider 6 to rotate, so that the slider 6 moves along the inside of the slide groove 8.

[0026] When the slider 6 reaches the bottom of the notch 7, the handle 3 drives the housing 2 upward, and the housing 2 drives the slider 6 out of the notch 7, thereby separating the housing 2 from the base 1, making it easier to inspect the interior of the housing 2.

[0027] Secondly, by providing a fixing ring 4, the bottom of the fixing ring 4 is in contact with the top surface of the base 1, so that the fixing ring 4 can shield the top of the slot 7, preventing dust and rain from entering the slot 7 and causing blockage;

[0028] Furthermore, the bottom of the movable rod 9 is fixedly connected to a limit ring 11, and a slot 12 is processed inside one end of the slider 6. The limit ring 11 is movably connected inside the slot 12. By providing the limit ring 11, the limit ring 11 is inserted into the slot 12, thereby limiting the slider 6 and fixing the housing 2.

[0029] Furthermore, a plurality of limiting holes 13 are machined on the top of the base 1. The bottoms of the limiting holes 13 are connected to the interior of the chute 8. The limiting ring 11 is movably connected to the interior of the limiting hole 13. When the limiting ring 11 is inserted into the interior of the slot 12, the bottom of the movable rod 9 sequentially passes through the fixing ring 4 and the interior of the base 1, thereby fixing the housing 2 to the top of the base 1.

[0030] Furthermore, a movable groove 15 is machined inside the fixed ring 4, and the movable rod 9 is movably connected to the inside of the movable groove 15. A limiting groove 14 is machined at the bottom of the movable groove 15, and the limiting ring 11 is movably connected to the inside of the limiting groove 14. The inner diameter of the movable groove 15 is smaller than the inner diameter of the limiting groove 14, and the inner diameter of the movable groove 15 is smaller than the diameter of the limiting ring 11.

[0031] Among them, when the handle 3 drives the movable rod 9 to move upward through the movable ring 5, the movable rod 9 will drive the limiting ring 11 to move upward, so that the limiting ring 11 will sequentially disengage from the slider 6 and the interior of the limiting hole 13 upward, so that the limiting ring 11 will enter the interior of the limiting groove 14, and then the shell 2 is rotated to make the slider 6 reach the notch 7. Since the inner diameter of the movable groove 15 is smaller than the diameter of the limiting ring 11, the limiting ring 11 will be located inside the limiting groove 14, and then the handle 3 is pulled to drive the fixed ring 4 to move upward, the fixed ring 4 will drive the shell 2 to move upward, and the shell 2 will drive the slider 6 to disengage from the interior of the notch 7, thereby facilitating the removal of the shell 2;

[0032] Furthermore, a return spring 10 is provided on the outside of the movable rod 9, and the top of the return spring 10 is fixedly connected to the bottom of the movable ring 5, and the bottom end of the return spring 10 is fixedly connected to the top of the fixed ring 4. By providing the return spring 10, when the movable ring 5 is pulled, the movable ring 5 will drive the return spring 10 to stretch, and when the movable ring 5 is released, the return spring 10 will reset and contract, and the return spring 10 will drive the movable rod 9 to move, so that the movable rod 9 drives the limit ring 11 to reset.

[0033] Working principle: By holding the two handles 3 and moving them upward, the handles 3 will drive the movable ring 5 and the movable rod 9 to move upward, so that the bottom of the movable rod 9 will be separated from the inside of the slider 6, and at the same time, the bottom of the movable rod 9 will be separated from the inside of the base 1, and then the shell 2 is rotated to make the shell 2 drive the fixed ring 4 to rotate. At the same time, the shell 2 will drive the slider 6 to rotate, so that the slider 6 moves along the inside of the slide groove 8. When the slider 6 reaches the bottom of the slot 7, the shell 2 is driven upward by the handles 3 to make the shell 2 drive the slider 6 to separate from the inside of the slot 7, thereby removing the shell 2 from the top of the base 1, making it convenient to inspect the inside of the shell 2.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
