Description
Technical Field
[0001] This utility model belongs to the field of lifting equipment technology, and further to the field of intelligent grab bucket bridge crane technology. Specifically, it relates to a compact, reliable, and highly stable laser radar installation device suitable for intelligent grab bucket bridge cranes. Background Technology
[0002] Currently, with rapid technological development, intelligent cranes have been widely applied in the steel industry. This is not only a development trend in the manufacturing sector but also an essential path for the transformation and development of the steel industry. Grab bucket bridge cranes are widely used in coal preparation workshops of steel plants, providing fuel transfer for blast furnace production and undertaking the tasks of storing and transporting blast furnace metallurgical coke and pulverized coal. Simultaneously, trucks, engineering vehicles, and cranes often operate together. Intelligent grab bucket bridge cranes require scanning the material surface in the storage area using lidar. A 3D modeling system is then used to create a 3D model of the material surface based on the scanned point cloud data. Based on this 3D model, the system intelligently plans the grab point location and the crane's travel path, enabling intelligent decision-making for grab point selection, throwing point selection, grab bucket height, and trolley / crane movement path planning. Combined with real-time data provided by the safety protection system, it automatically avoids safety passages and cranes operating in adjacent areas, automatically completing the tasks assigned by the user through the client interface.
[0003] The installation location for a lidar system should generally be chosen at a relatively high position with a wide field of view. Furthermore, the mounting method must be considered. First, a suitable bracket should be selected to secure the lidar, paying attention to its strength and durability. Second, stability is crucial; the lidar must be securely fixed to prevent damage or malfunction due to external interference. A reliable power supply is required to ensure normal operation. Select a suitable power module based on the lidar's power requirements. Lidar systems need to transmit data signals, typically using standard network cables. It's important to note that the cable length should be chosen appropriately, avoiding both excessive length and insufficient length. For crane-mounted lidar systems, vertical and horizontal adjustments are necessary. Vertically, the lidar should face the ground, ensuring the laser beam is perpendicular to the ground; horizontally, the laser beam should be parallel to the ground.
[0004] Therefore, researching and developing a compact, reliable, and highly stable lidar installation device suitable for intelligent grab bucket bridge cranes is key to solving this problem. Utility Model Content
[0005] The purpose of this utility model is to provide a compact, reliable, and highly stable laser radar installation device suitable for intelligent grab bucket bridge cranes.
[0006] The purpose of this utility model is achieved as follows: It includes a movable support, a fixed support, bolt pair I, a laser radar mounting base, bolt pair II, bolt pair III, and a positioning pin. The movable support is located inside the angle steel surrounding the crane platform; the movable support is equipped with a hinge, allowing it to rotate; the fixed support is located outside the angle steel surrounding the crane platform; the upper end plate of the movable support overlaps the fixed support; the movable support and the fixed support are connected by bolt pair I; a laser radar mounting base is located below the upper end plate of the movable support; the movable support and the laser radar mounting base are connected by bolt pair II; a positioning pin is provided between the movable support and the laser radar mounting base; and bolt pair III is provided on the laser radar mounting base for mounting the laser radar.
[0007] This utility model consists of a movable bracket, a fixed bracket, bolt pair I, a laser radar mounting base, bolt pair II, bolt pair III, and a locating pin. The movable bracket is equipped with a hinge, allowing it to be flipped, facilitating the installation and subsequent maintenance of the laser radar. The movable bracket and the fixed bracket are connected by bolt pair I to enhance the overall stability of the device. The laser radar and the laser radar mounting base are connected by bolt pair III, ensuring the flexibility of disassembly, as well as the stability and reliability of the connection. The fixed base of the movable bracket is equipped with stiffening plates to enhance the stability and reliability of the connection between the movable bracket and the angle steel of the crane walkway. The fixed bracket is welded to the lower part of the checkered steel plate of the crane walkway through stiffening plates to enhance the stability and reliability of the fixed bracket.
[0008] The installation steps for this device are as follows:
[0009] 1. Mark the predetermined position on the angle steel of the crane walkway. Spot weld the fixed seat of the movable bracket to the angle steel of the crane walkway. Then drill connecting holes with the fixed bracket. Connect the fixed bracket to the movable bracket through bolt pair I. Then spot weld the fixed bracket to the angle steel of the crane walkway.
[0010] 2. Install the lidar on the lidar mounting base, use locating pins to lock the movable bracket to the lidar mounting base, and fix it with bolt pair II. Then adjust the horizontal and vertical polarization of the lidar. After the lidar test meets the standards, weld the movable bracket, fixed bracket and the angle steel of the crane walkway to the edge firmly.
[0011] This invention solves the technical problems of installing and flexibly maintaining lidar on intelligent grab bucket bridge cranes. It satisfies the requirement that the lidar be installed at a relatively high position with a wide field of view, while the fixed bracket has sufficient strength and durability to ensure stable and secure operation of the lidar. This guarantees relatively high scanning accuracy of the lidar in both vertical and horizontal directions during operation of the intelligent grab bucket bridge crane. Ultimately, it achieves stable operation of two sets of laser scanning systems during crane operation, observing the material level in the coal and coke silo. The laser scanner acquires accurate point cloud data of the actual contour of the coal and coke silo, processes the point cloud data to accurately calculate and output the three-dimensional spatial position of the coal pile, scans and receives the position contour, calculates the three-dimensional spatial position, and guides the crane to complete the unloading operation. The lidar can be hinged to the inside of the crane platform, facilitating later maintenance and reducing the difficulty of lidar maintenance, lowering the safety hazards of high-altitude lidar maintenance operations, and increasing the safety of lidar maintenance.
[0012] This utility model has a compact structure and reliable connection, which can improve the stability of the connection between the lidar and the intelligent grab bucket bridge crane and the smooth operation of the lidar. Attached Figure Description
