Description

Technical Field

[0001] This utility model relates to the field of engineering machinery and lifting equipment, and in particular to a high-precision positioning device for cranes. Background Technology

[0002] Cranes, as core equipment in industrial production, logistics, and engineering construction, undertake critical tasks such as material handling, equipment hoisting, and component assembly, covering a wide range of scenarios from small-scale workshop operations to large-scale engineering sites. However, with the expansion of industry scale and the increasing complexity of operating environments, the phenomenon of mixed human and machine activity in crane operation areas is becoming increasingly prominent, and safety risks are increasing exponentially. Positioning accuracy, as a core indicator of crane operation, not only directly determines operational efficiency and product quality, but also becomes a key line of defense for ensuring human and machine safety and avoiding systemic risks.

[0003] The existing crane positioning mainly uses the DPS positioning system. This DPS system is linked with the crane control system to build a three-dimensional digital model of the crane and the electronic fence operation, realizing the synchronous mapping between the physical space and the virtual system. The staff can remotely monitor the movement status of the equipment in the control center, predict the changes in the load stress of the crane boom, and realize the positioning of the crane.

[0004] Regarding the aforementioned technologies, in logistics operations, although the crane DPS positioning system can achieve positioning, the dynamic load changes during boom movement often cause the main body of the equipment to sway, resulting in unstable signal reception and thus affecting the stability of signal reception. Utility Model Content

[0005] To improve the stability of the positioning device, this application provides a high-precision positioning device for cranes.

[0006] This application provides a high-precision positioning device for a crane, which adopts the following technical solution: A high-precision positioning device for a crane includes a main body, a movable support plate on one side of the main body, the movable support plate being rotatably connected to the main body, the main body being vertically upward in its natural state, the main body rotating around the movable support plate when the movable support plate rotates, a connecting member between the movable support and the crane being provided, the connecting member being used to connect the movable support and the crane together, and a signal transmission component on one side of the main body being used to detect and transmit the position of the crane.

[0007] By adopting the above technical solution, the movable support is connected to the crane via a connector, thereby connecting the main body to the crane. The signal transmission component provides position feedback for crane operation, reducing safety risks such as collisions and deviations, and improving operational accuracy. In its natural state, the main body is vertically upward. When the crane rotates the movable support during operation, the main body can rotate around the movable support, ensuring that the main body always remains vertical and upward. This ensures the stability of the main body on the crane, reduces the swaying of the main body caused by the crane boom during movement, and thus reduces the impact on signal reception, thereby improving the stability of the positioning device.

[0008] Optionally, the connector includes two magnetic bases, which have magnetic force. The two magnetic bases are fixed to the lower end of the movable support plate and are located at both ends of the movable support plate, respectively.

[0009] By adopting the above technical solution, the design of the magnetic base simplifies the installation and disassembly of the connector. The magnetic base possesses magnetic force; simply bring it close to the adsorption surface, and installation can be quickly completed using magnetic force, without the need for complex tools or cumbersome fixing operations. Similarly, when disassembly is required, simply apply a certain external force to overcome the magnetic force, and the connector can be easily removed, improving the ease of use of the positioning device.

[0010] Optionally, connecting rods are provided on both sides of the movable support plate, and the connecting rods pass through the movable support plate and are rotatably connected to the main body.

[0011] By adopting the above technical solution, the connecting rods set on both sides of the movable support plate pass through the movable support plate and are rotatably connected to the main body, realizing the rotatable connection between the movable support plate and the main body. In its natural state, the main body is vertically upward. When the movable support plate moves under the drive of the crane, it can rotate around the main body, reducing the movement of the main body and ensuring the stability of the main body in use.

[0012] Optionally, a display screen is provided on the side of the main body away from the back panel. When in operation, the display screen shows the position of the crane.

[0013] By adopting the above technical solution, the crane position information displayed on the screen can be recorded and stored, providing a basis for subsequent data analysis. By analyzing the crane position data, information such as the crane's usage frequency and operating trajectory can be understood, thereby optimizing the crane's scheduling and management strategies, and improving equipment utilization and overall operational efficiency.

[0014] Optionally, a number of holes are opened on one side of the movable support plate, and a hanging chain is provided on one side of the movable support plate, with both ends of the hanging chain fastened to the holes.

[0015] By adopting the above technical solution, several holes are opened on one side of the movable support plate and the two ends of the hanging chain are fastened to the holes. During the use of the positioning device, the device can be suspended or fixed by the hanging chain to meet different usage scenarios and installation requirements, thereby improving the flexibility and convenience of the device.

[0016] Optionally, the signal transmission components include a satellite receiving antenna and a base station communication component. The satellite receiving antenna receives satellite signals to monitor whether the crane height and the distance between the boom and the electronic fence are within a safe area. The crane is equipped with a control console for controlling the crane. The base station communication component is used to transmit the received signals to the control console.

[0017] By adopting the above technical solution, the satellite receiving antenna monitors the crane height by receiving satellite signals. At the same time, the satellite receiving antenna can also monitor the distance between the boom and the electronic fence, and keep track of the distance between the boom and the danger zone in real time. The signal is then transmitted to the control console through the base station communication component. Managers can keep track of the crane's position and operating status at any time without being on-site, thus improving the convenience of use.

[0018] Optionally, a warning light bulb is provided on the upper part of the main body. When the crane moves near the electronic fence, the warning light bulb will light up red to sound an alarm.

[0019] By adopting the above technical solution, when the crane is near the electronic fence, the strong red light emitted by the warning light bulb can be clearly seen, attracting the attention of the operator and allowing them to adjust the crane's direction and speed in time, keeping the crane operating within a safe area. At the same time, it can also serve as a warning to surrounding workers and pedestrians, improving the safety of the device.

[0020] Optionally, the upper part of the main body is provided with a lamp cover, which is detachably connected to the main body. The lamp cover has a mounting groove, and the warning light bulb is located in the mounting groove and fixedly connected to the inner wall of the mounting groove.

[0021] By adopting the above technical solution, the lamp cover supports and protects the warning light bulb, and the lamp cover is detachably connected to the main body, which facilitates the disassembly and replacement of the warning light bulb and improves the convenience of use.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When the crane rotates the movable support during operation, the main body can rotate around the movable support, keeping the main body vertical and ensuring its stability on the crane. This reduces the swaying of the main body caused by the crane boom during movement, which could affect signal reception and improve the stability of the positioning device. 2. The magnetic base has magnetic force. Simply bring the magnetic base close to the adsorption surface and use the magnetic force to quickly complete the installation, improving the convenience of using the positioning device; 3. When the crane is near the electronic fence, the strong red light emitted by the warning light bulb can be clearly seen, attracting the operator's attention and allowing them to adjust the crane's direction and speed in time, thus improving the safety of the device.

[0027] This application discloses a high-precision positioning device for a crane. Example

[0028] Reference Figure 1 and Figure 2 A high-precision positioning device for a crane includes a main body 1. A movable support plate 11 is provided on one side of the main body 1, the width of which is less than the width of the main body 1. Connecting rods 111 are provided on both sides of the movable support plate 11, passing through the movable support plate 11 and rotatably connected to the main body 1. In its natural state, the main body 1 is vertically upward. During operation, the movable support plate 11 is connected to the crane, and the crane rotates the movable support plate 11. Under the rotation of the connecting rods 111, the movable support plate 11 rotates around the main body 1, reducing the probability of the main body 1 rotating and ensuring that the main body 1 remains vertically upward. This ensures the stability of the main body 1 on the crane and reduces the swaying of the main body 1 caused by the crane boom during movement, thus improving signal reception and enhancing the stability of the positioning device. Simultaneously, the movable connecting rods 111 facilitate the disassembly and installation of the main body 1 and the movable support plate 11, making maintenance and cleaning of the main body 1 easier and improving the convenience of the device.

[0029] Reference Figure 1 and Figure 2The lower end of the movable support plate 11 is provided with two magnetic bases 12, located at opposite ends of the movable support plate 11. The magnetic bases 12 possess magnetic force. When connecting the movable support plate 11 to the crane, simply bring the magnetic base 12 close to the adsorption surface; the magnetic force will quickly complete the installation without the need for complex tools or cumbersome fixing operations. Similarly, when disassembly is required, simply apply a certain external force to overcome the magnetic force to easily remove the connector, improving the ease of use of the positioning device.

[0030] Reference Figure 2 The main body 1 has a switch 16 at the lower end, which controls the operation of the main body 1. The main body 1 has an RTK positioning device inside. When the positioning device is used, the switch 16 is turned on and the positioning device is started. The operation is convenient and improves the ease of use of the device. The main body 1 has a charging port 17 at the lower end, so that the charging cable can be naturally led out from below. In this way, the device can maintain a stable placement during the charging process.

[0031] Reference Figure 1 and Figure 2 A signal transmission component 13 is provided on one side of the machine body. The signal transmission component 13 includes a satellite receiving antenna 131 and a base station communication component 132. The satellite receiving antenna 131 monitors the height of the crane by receiving satellite signals. At the same time, the satellite receiving antenna 131 can also monitor the distance between the boom and the electronic fence, so as to keep track of the distance between the boom and the danger zone in real time. The crane is equipped with a control console for controlling the crane. The signal is then transmitted to the control console through the base station communication component 132. The management personnel do not need to be on site to keep track of the position and operating status of the crane at any time, which improves the convenience of use.

[0032] Reference Figure 1 The movable support plate 11 has several holes 113 on one side, and a hanging chain 112 is provided on one side of the movable support plate 11. Both ends of the hanging chain 112 are fastened to the holes 113. During the use of the positioning device, the hanging chain 112 can be suspended from the boom of the crane. The device can be suspended or fixed by the hanging chain 112 to meet different usage scenarios and installation requirements, and improve the flexibility and convenience of the device.

[0033] Reference Figure 1 The upper part of the main body 1 is equipped with a warning light bulb 152. When the crane is driven near the electronic fence, the warning light bulb 152 lights up red and alarms. At the same time, the control panel emits an alarm sound. The strong red light emitted by the warning light bulb 152 can be clearly seen, attracting the attention of the operator and allowing them to adjust the crane's direction and speed in time, so that the crane can operate within a safe area. At the same time, it can also serve as a warning to the surrounding staff and pedestrians, improving the safety of the device.

[0034] Reference Figure 1The upper part of the main body 1 is provided with a lamp cover 15, which is detachably connected to the main body 1. The lamp cover 15 has a mounting groove 151, and the warning light bulb 152 is located in the mounting groove 151 and fixedly connected to the inner wall of the mounting groove 151. The lamp cover 15 supports and protects the warning light bulb 152, and the lamp wire connected to the warning light bulb 152 is stored inside the lamp cover 15 to keep the device tidy. The lamp cover 15 and the main body 1 are detachably connected by screws. When maintenance or replacement is required, there is no need to disassemble the entire structure of the main body 1. Just quickly remove the lamp cover 15 to directly contact the warning light bulb 152 in the mounting groove 151, and easily complete the maintenance or replacement operation, improving the convenience of use.

[0035] Reference Figure 1 The main body 1 is equipped with a display screen 14 on the side away from the back plate. When the main body 1 is working, the display screen 14 displays the position of the crane. The crane position information displayed on the display screen 14 can be recorded and stored to provide a basis for subsequent data analysis. By analyzing the crane position data, information such as the crane's usage frequency and running trajectory can be understood, thereby optimizing the crane's scheduling and management strategies and improving the utilization rate of the equipment and the overall operating efficiency.

[0036] The implementation principle of the high-precision positioning device for a crane in this application embodiment is as follows: the magnetic base 12 is brought close to the crane, and the movable support plate 11 is connected to the crane under the action of magnetic force, thereby connecting the main body 1 to the crane. When the crane is working, the boom will drive the movable support plate 11 to move. At this time, under the action of the connecting rod 111, the movable support plate 11 rotates around the main body 1, and the main body 1 always remains vertical and upward, reducing the shaking of the main body 1 caused by the boom of the crane when it moves, thus affecting the signal reception, ensuring the continuity and accuracy of signal reception and transmission, thereby improving the stability of the positioning device.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
