[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 and Figure 3 The present invention provides an embodiment of a crane main beam detection structure, comprising a housing 1, wherein the housing 1 has a fixing slot 5 defined therein, a motor 2 fixedly connected to the inner wall of the fixing slot 5, a threaded rod 3 fixedly connected to the output end of the motor 2, a threaded slider 4 threadedly connected to the outer surface of the threaded rod 3, a groove 7 defined on the outer surface of the threaded slider 4, a detector 13 slidably connected to the inner wall of the groove 7, a level 16 fixedly connected to the outer surface of the detector 13, an infrared rangefinder 15 fixedly connected to the other end of the level 16, a disassembly assembly mounted inside the threaded slider 4, and used to disassemble and assemble the detector 13. The other end of the threaded rod 3 is rotatably connected to the inner wall of the fixing slot 5.

[0031] Specifically, the output end of the motor 2 plays a fixing role on the threaded rod 3, so that by starting the motor 2, the threaded rod 3 is driven to rotate, and the fixing groove 5 plays a limiting role on the threaded slider 4, so that the threaded slider 4 moves along the inner wall of the fixing groove 5, and the threaded rod 3 plays a guiding role on the threaded slider 4, so that the threaded slider 4 can be moved in a directional manner, the threaded slider 4 plays a fixing role on the spirit level 16, and the spirit level 16 plays a fixing role on the infrared rangefinder 15, so that the infrared rangefinder 15 at the bottom of the threaded slider 4 can measure distances at different positions, and under the leveling effect of the spirit level 16, the infrared rangefinder 15 can maintain a horizontal level for measurement, thereby ensuring the accuracy of the measurement, so that the staff can conveniently inspect the crane main beam.

[0032] Reference Figure 2 and Figure 3 The disassembly assembly includes a connecting groove 8, which is provided inside the threaded slider 4. A connecting slider 10 is slidably connected to the inner wall of the connecting groove 8. A clamping block 11 is fixedly connected to one side of the connecting slider 10, and a pull rod 6 is fixedly connected to the other side of the connecting slider 10. A spring 9 is sleeved on the outer surface of the pull rod 6. A clamping groove 12 is provided on one side of the detector 13. One end of the clamping block 11 has a circular longitudinal section, and the other end of the clamping block 11 is plugged into the clamping groove 12.

[0033] Specifically, one end of the pull rod 6 fixes the connecting slider 10, so by pulling the pull rod 6, the connecting slide 8 limits the connecting slider 10, thereby driving the connecting slider 10 to move along the inner wall of the connecting slide 8, and fixes the spring 9 on one side of the connecting slider 10, so that the spring 9 can be expanded and contracted, and fixes the card block 11 on the other side of the connecting slider 10, thereby driving the card block 11 to move out of the inner wall of the card slot 12, and limits the detector 13 in the groove 7, so that the outside of the detector 13 can be moved along the inner wall of the groove 7 and thus taken out, so that the staff can conveniently disassemble and maintain the detector 13.

[0034] Reference Figure 2 and Figure 3 The exterior of the clamping block 11 is slidably connected to the inner wall of the clamping slot 12, which in turn is slidably connected to the inner wall of the threaded slider 4. One end of the spring 9 is fixedly connected to one side of the connecting slider 10, while the other end of the spring 9 is fixedly connected to the inner wall of the connecting slot 8. The exterior of the threaded slider 4 is slidably connected to the inner wall of the fixed slot 5. The exterior of the detector 13 is fixedly connected to the alarm 14.

[0035] Specifically, the card slot 12 and the card block 11 cooperate with each other, so that the detector 13 can be fixed in the groove 7, thereby facilitating the disassembly and assembly of the detector 13. The connecting slider 10 fixes the spring 9, so that when the connecting slider 10 moves, it can synchronously drive the spring 9 to expand and contract, thereby facilitating the disassembly step. Under the action of the fixing groove 5, the threaded rod 3 is more stable when working, and the detector 13 fixes the alarm 14. In this way, under the action of the alarm 14, danger can be prevented in advance.

[0036] Working principle: When using this device, by installing the box 1 at the bottom of the crane main beam, the motor 2 is started to drive the threaded rod 3 to rotate, and then the threaded slider 4 is moved along the inner wall of the fixed groove 5, so that the threaded slider 4 can be moved in a directional manner, so that the infrared rangefinder 15 at the bottom of the threaded slider 4 can measure the distance at different positions, and under the action of the level 16, the infrared rangefinder 15 can be kept horizontal for measurement, thereby ensuring the accuracy of the measurement, so that the staff can conveniently inspect the crane main beam, thereby reducing the measurement risk;

[0037] When the detection device needs to be disassembled and repaired, the pull rod 6 is pulled to drive the connecting slider 10 to move along the inner wall of the connecting slide groove 8, so that the spring 9 is extended and retracted, thereby driving the card block 11 to move out of the inner wall of the card slot 12, so that the outside of the detector 13 can be moved along the inner wall of the groove 7 and taken out. In this way, the detector 13 can be disassembled and maintained conveniently, thereby improving the efficiency of the staff.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
