[0001] This utility model relates to the field of measuring the outline dimensions of oversized cargo, specifically a mobile device for measuring the outline dimensions of oversized cargo. Background Technology

[0002] With the development of my country's modern industry and the needs of military transportation, the demand for railway transportation of oversized and overweight goods will increase. The transportation of oversized and overweight goods is different from that of ordinary goods, and the difficulty of transportation organization is significantly higher. For example, before loading oversized and overweight goods, it is necessary to accurately measure the external dimensions of the goods, select appropriate loading vehicles, determine an economical and reasonable loading and reinforcement plan, and complete strict approval procedures. During the operation, multiple departments are required to coordinate and cooperate, and conduct inspections and handovers.

[0003] Oversized cargo is usually loaded, unloaded, and inspected manually, often using traditional measuring tools such as tape measures. This process is time-consuming and requires climbing vehicles. Furthermore, due to varying levels of experience and skill, the accuracy of the measurements is difficult to guarantee. As technology has advanced, handheld mobile measuring devices are now commonly used to measure the dimensions of oversized cargo.

[0004] Currently, handheld mobile measuring devices are mostly used by manually rotating them around oversized cargo. When using handheld mobile measuring devices in rainy or snowy weather, operators need to hold an umbrella while moving the device, which is inconvenient. In addition, rainwater can easily get into the handheld mobile measuring device, affecting its service life.

[0005] Therefore, we proposed a mobile device for measuring the outline dimensions of oversized cargo in order to solve the problems mentioned above. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mobile oversized cargo contour dimension measuring device, including a placement base and a handheld rod fixedly installed on the upper end of the placement base. A measuring body is provided at the upper end of the handheld rod, a panoramic camera is installed at the upper end of the measuring body, a multi-line lidar is installed at one end of the measuring body, a fixing component is threadedly fixedly installed on the upper end of the outer wall of the handheld rod, and a shielding component is fixedly installed at one end of the fixing component. The shielding component is set to shield the upper end of the handheld device used externally in rainy weather.

[0008] The shielding assembly includes a transparent long plate and a clamping mechanism fixedly installed on both sides of the lower end of the transparent long plate. The clamping mechanism is configured to fix the paper block placed at the lower end of the transparent long plate.

[0009] Preferably, the fixing component includes a semi-circular clamping block and threaded grooves respectively formed in the middle of the inner wall of the semi-circular clamping block on both sides.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-6 A mobile oversized cargo contour dimension measuring device includes a base 1 and a handheld rod 2 fixedly installed on the upper end of the base 1. A measuring body 3 is provided at the upper end of the handheld rod 2, a panoramic camera 4 is installed at the upper end of the measuring body 3, a multi-line lidar 5 is installed at one end of the measuring body 3, a fixing component 6 is threadedly fixedly installed on the upper end of the outer wall of the handheld rod 2, and a shielding component 7 is fixedly installed at one end of the fixing component 6. The shielding component 7 is set to shield the upper end of the handheld device used externally in rainy weather.

[0025] The handheld measuring device consists of a multi-line lidar 5, a panoramic camera 4, and a measuring body 3. The measuring body 3 contains an IMU (Inertial Measurement Unit) installed inside, a scanning speed-stabilizing motor, a front-end processing algorithm, and an internal computer responsible for data preprocessing and storage. The multi-line lidar 5 is responsible for rapid multi-point ranging of the target and generating point cloud data. The panoramic camera 4 is responsible for capturing panoramic images of the target. The IMU inside the measuring body 3 records the movement path and speed of the handheld device. The scanning speed-stabilizing motor drives the multi-line lidar to rotate, expanding the scanning imaging range. The front-end algorithm on the internal computer is responsible for processing and fusing the information generated by the lidar, IMU, panoramic camera 4, and scanning motor to generate a four-dimensional point cloud data model, which is then stored on the internal computer.

[0026] During field data collection, the handheld measuring device needs to be controlled via an app installed on an Android phone. The app's functions include starting and ending field data collection, image preview, and field data preprocessing. See the instruction manual for details. Figure 5 .

[0027] When using the handheld measuring device, data is collected by moving the handheld device around the object to be measured. The multi-line lidar 5 serves as the ranging core, and the cyclic scanning method of the speed-stabilized motor achieves panoramic, blind-spot-free illumination measurement of the target. The final task is completed through field software and office software respectively.

[0028] The field software is responsible for controlling the lidar acquisition commands, previewing the acquired data, and preprocessing the data. The office software uses processing algorithms to reconstruct and solve the raw data, thereby generating a target point cloud map. Then, through the office software's human-computer interaction function, it annotates the dimensions of targets of interest to the client and generates cargo consignment instructions, three-view drawings, and tables of over-limit and over-limit points, completing the final task. This solution facilitates digital management and provides technical support for target data traceability and target modeling. (See the appendix in the manual.) Figure 4 Instruction manual attached Figure 5 Included with instruction manual Figure 6 .

[0029] The fixing component 6 includes a semi-circular clamp 61 and threaded grooves 62 respectively opened in the middle of the inner wall of the semi-circular clamp 61. The semi-circular clamp 61 is wrapped around the upper end of the outer wall of the hand handle 2.

[0030] An extension block 63 is fixedly installed at the middle of one end of the outer wall of the semi-circular clamping block 61. A support rod 64 is fixedly installed at the middle of one end of the extension block 63. The upper side of the support rod 64 is fixedly installed at the middle of one end of the transparent long plate 71.

[0031] A threaded rod 65 is threadedly connected to the inner cavity of the threaded groove 62. A bearing 66 is installed at one end of the threaded rod 65, and a clamping block 67 is installed at the other end of the bearing 66. The threaded rod 65 is threadedly connected to the inner cavity of the threaded groove 62. By rotating the threaded rod 65, the bearing 66 and the clamping block 67 are pressed and fixed on the outer wall of the hand handle 2.

[0032] Since threaded rods 65, bearings 66 and clamping blocks 67 are provided on both sides of the inner wall of the semicircular clamping block 61, the semicircular clamping block 61 is pressed and fixed on the outer wall of the hand handle 2.

[0033] The shielding assembly 7 includes a transparent long plate 71 and a pressing mechanism 72 fixedly installed on both sides of the lower end of the transparent long plate 71. The pressing mechanism 72 is configured to fix the paper block placed at the lower end of the transparent long plate 71.

[0034] In this embodiment: When using the handheld measuring device in rainy or snowy weather, the semi-circular clamp 61 can be first fitted onto one side of the outer wall of the handheld rod 2. By tightening the threaded rod 65, the bearing 66 and the clamp 67 are moved, so that the clamp 67 is tightly attached to both sides of the outer wall of the handheld rod 2, thereby completing the fixed installation of the semi-circular clamp 61 on the outer wall of the handheld rod 2. At the same time, since a support rod 64 is fixedly installed in the middle of one side of the outer wall of the semi-circular clamp 61, and a transparent long plate 71 is fixedly installed on the upper side of the support rod 64, the lower end of the handheld measuring device can be directly blocked by the transparent long plate 71 when the handheld measuring device is used outdoors in rainy or snowy weather, thus improving the convenience of using the handheld measuring device in rainy or snowy weather.

[0035] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 The pressing mechanism 72 includes a herringbone block 721 and elastic elements 722 that are linearly and equally spaced and fixedly installed on one side of the inner wall of the herringbone block 721. A pressure plate 723 is fixedly installed on the upper end of the elastic element 722. The pressure plate 723 is movably extended and retracted in the inner cavity of the herringbone block 721 under the elastic force of the elastic element 722.

[0036] In this embodiment: Since the transparency of the transparent long plate 71 will not affect the shooting brightness of the panoramic camera 4, and if the panoramic camera 4 causes overexposure during shooting, the ambient brightness can be alleviated by placing paper at the lower end of the transparent long plate 71. By placing the two ends of the paper on the lower sides of the transparent long plate 71 respectively, and the two ends of the paper pass through the inner cavity of the herringbone block 721, the pressure plate 723 in the inner cavity of the herringbone block 721 will automatically clamp the paper under the elastic force of the elastic element 722, thus completing the fixed setting of the paper, which is convenient to use.

[0037] Working principle: When using the handheld measuring device in rainy or snowy weather, the semi-circular clamp 61 can be first fitted onto one side of the outer wall of the handheld rod 2. By tightening the threaded rod 65, the bearing 66 and the clamp 67 are moved, so that the clamp 67 is tightly attached to both sides of the outer wall of the handheld rod 2, thus fixing the semi-circular clamp 61 to the outer wall of the handheld rod 2. At the same time, since a support rod 64 is fixedly installed in the middle of one side of the outer wall of the semi-circular clamp 61, and a transparent long plate 71 is fixedly installed on the upper side of the support rod 64, the lower end of the handheld measuring device can be directly blocked by the transparent long plate 71, thereby making the handheld measuring device... When used outdoors in rainy or snowy weather, the falling rain and snow can be directly blocked by the transparent long plate 71. Since the transparency of the transparent long plate 71 will not affect the shooting brightness of the panoramic camera 4, and if the panoramic camera 4 causes overexposure during shooting, the ambient brightness can be alleviated by placing paper at the lower end of the transparent long plate 71. By placing the two ends of the paper on the lower sides of the transparent long plate 71 respectively, the two ends of the paper pass through the inner cavity of the herringbone block 721. The pressure plate 723 in the inner cavity of the herringbone block 721 will automatically clamp the paper under the elastic force of the elastic element 722, thus completing the fixing of the paper.
