[0002] Crane detection is an important link to ensure the safe operation of lifting machinery, involving various detection contents and methods. For the detection of the shape, straightness, and balance of the tracks in a crane, a laser scanning device is mostly used for detection, which can achieve non-contact detection and ensure the accuracy of the detection results. The laser scanning device is divided into two types: a portable one with a small volume and a fixed one with a large volume. Among them, the portable laser scanning device is held and used, with higher flexibility.

[0003] When using a portable laser scanning device, the staff holds the device to perform laser scanning on structures such as tracks in the crane, and the data obtained by scanning is fed back to the computer, and the relevant characteristics of the current structure can be obtained by using the computer. However, in the portable laser scanning device, there is no special holding structure, resulting in extremely inconvenient holding of the laser scanning device. In some laser scanning devices with a holding rod, the holding rod is fixedly arranged and cannot be unfolded for use, resulting in that the entire device can only be held for use and cannot be temporarily fixed on the platform for use, making the use mode of the device single and the use adaptability poor. Moreover, there is no protective cover at the laser scanning lens, and the laser scanning lens cannot be effectively protected when not in use and is easily damaged. Summary of the Utility Model

Specific embodiments

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] As Figures 1 - 4 shown, a laser scanning device for crane detection includes a scanner main body 1. A detection head 2 is provided at the top of the scanner main body 1, and a scanning lens 3 is provided on the detection head 2. A handheld structure 4 is provided at the bottom of the scanner main body 1, and a protection structure 6 is installed at the top of the scanner main body 1. The detection head 2 and the scanning lens 3 are located inside the protection structure 6. An indicator light 5 is provided on the scanner main body 1, and a cable joint 7 is provided at the bottom position of the scanner main body 1. The protection structure 6 includes a threaded joint 601, a protective cover 602 and an internal thread 603. The threaded joint 601 is fixed to the top of the scanner main body 1. The internal thread 603 is opened at the bottom end of the protective cover 602, and the internal thread 603 is threadedly connected with the threaded joint 601. The protective cover 602 is fixed to the top of the scanner main body 1 through the internal thread 603 and the threaded joint 601. By providing the protection structure 6 at the upper end of the scanner main body 1, the scanning lens 3 on the detection head 2 can be effectively protected, ensuring that the scanning lens 3 is hidden when not in use and avoiding damage to the scanning lens 3 caused by external factors.

[0019] When using a laser scanning device to scan and detect structures such as tracks in a crane, when it is necessary to hold the device by hand, the handheld structure 4 is folded together, and then held in the hand. One end of the cable is connected to the cable connector 7 on the scanner main body 1, and the other end is connected to a portable industrial computer for detection. After starting the scanning device, the indicator light 5 lights up, and then the protective cover 602 is rotated. The protective cover 602 rotates on the threaded joint 601 through the internal thread 603 until the protective cover 602 is removed from the upper end of the scanner main body 1. The scanning lens 3 on the detection head 2 is directed at the relevant structure. The laser generated inside the scanner main body 1 is emitted through the scanning lens 3 and acts on the structure in the crane. The scanned structure reflects the laser, and the device receives the reflected laser for data transmission. The industrial computer analyzes and compares the data reflected back to obtain the relevant data of the detected structure, thus completing the detection work of some structures in the crane. During the use of the laser scanning device, the handheld structure 4 can also be unfolded, and the scanner main body 1 can be fixed by using screws in cooperation with the handheld structure 4, and then the entire device can be fixed for use. When the device is used up, the protective cover 602 is installed on the threaded joint 601 by using the internal thread 603, and the detection head 2 is covered by the protective cover 602 for protection to prevent the scanning lens 3 from being damaged due to external factors.

[0020] Through the above implementation scheme, the handheld structure 4 includes a fixed seat 401, a handheld rod 402, a rotating block 403, a contact surface 404, a magnet 405, a supporting rubber block 406, and a waist-shaped counterbore 407. The fixed seat 401 is fixed at the bottom of the scanner main body 1. The handheld rod 402 is fixedly connected to the rotating block 403, and the rotating block 403 is rotatably connected to the fixed seat 401. The fixed seat 401, the handheld rod 402, and the rotating block 403 are distributed in a circular array at the bottom of the scanner main body 1. The contact surface 404 is arranged on the handheld rod 402, and an assembly groove is provided at the contact surface 404 on the handheld rod 402. The magnet 405 is embedded in the assembly groove at the contact surface 404 on the handheld rod 402. The supporting rubber block 406 is fixed on the handheld rod 402. The waist-shaped counterbore 407 is opened on the handheld rod 402. Through the provided handheld structure 4, the handheld rod 402 is installed on the fixed seat 401 through the rotating block 403. When it is necessary to hold it by hand, all the handheld rods 402 can be rotated and folded together to form a complete round rod, which is convenient for holding and using. The magnet 405 is embedded and installed on the contact surface 404. After the handheld rods 402 are folded together, the magnets 405 are adsorbed together to ensure the stability after the handheld rods 402 are folded together and guarantee the holding effect. The handheld rod 402 can also be unfolded for use. In cooperation with the waist-shaped counterbore 407 and screws, the unfolded handheld rod 402 can be fixed to a suitable platform, so that the entire device is fixedly installed and used, and the usage method is diversified. The supporting rubber block 406 plays a supporting role and improves the stability of the device during installation.

[0021] When using the device, when it is necessary to hold the device by hand for use, the hand-held rod 402 is in a closed state, the abutting surfaces 404 on the hand-held rod 402 are in contact with each other, and at the same time, the magnets 405 on the adjacent hand-held rods 402 are adsorbed together, which can ensure the stability after the hand-held rod 402 is closed. Then, the staff holds the round rod formed by the closing of the hand-held rod 402 with the palm of the hand and can hold and use the device. When it is necessary to fix the device for use, the hand-held rod 402 is unfolded. The hand-held rod 402 rotates on the fixed seat 401 through the rotating block 403 until the supporting rubber block 406 on the hand-held rod 402 is disengaged from the bottom of the scanner main body 1. At this time, the hand-held rod 402 is in a horizontal state and is stably supported through the inner plane of the hand-held rod 402. The screw is inserted into the kidney-shaped counterbore 407 so that the screw is screwed into the screw hole on the platform, thereby fixing the hand-held rod 402. Under the combined action of the hand-held rod 402, the supporting rubber block 406, the rotating block 403 and the fixed seat 401, the scanner main body 1 is stably installed on the platform, and after connecting the cable, it can be used.
