Abstract

Technical Field
[0001] This utility model belongs to the field of self-propelled device technology, and more specifically, it relates to a self-propelled device with an abnormal alarm function. Background Technology
[0002] Equipment relocation is a high-risk operation involving human and machine cooperation in ports, and it requires the cooperation of large mobile machinery to complete. In view of the high risks and high costs of equipment relocation, self-propelled devices are needed.
[0003] Based on existing technology, it has been found that the existing self-propelled devices commonly used in ports rely on the cooperation of wheels and rails to achieve movement, resulting in a single and inflexible route. Furthermore, existing self-propelled devices require shutdown when there is strong wind during port operations, as they lack wind monitoring structures. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a self-propelled device with an abnormal alarm function. This solves the problem that existing self-propelled devices, such as those used in ports, typically rely on the interaction of wheels and rails for their movement, resulting in limited mobility and a lack of flexibility. Furthermore, existing self-propelled devices require shutdown in port operations with strong winds, as they lack wind monitoring mechanisms.
[0005] This utility model discloses a self-propelled device with an abnormality alarm function, which is achieved by the following specific technical means:
[0006] A self-propelled device with an abnormal alarm function includes an installation mechanism, a walking mechanism, and a connecting mechanism;
[0007] The installation mechanism is provided with a walking mechanism at its bottom; the connecting mechanism is provided at the top of the installation mechanism.
[0008] The installation mechanism includes: a main body, with a base plate at the bottom of the main body; a servo motor A is mounted on the base plate; and a gear A is mounted on the output shaft of the servo motor A.
[0009] The walking mechanism includes: a gear B; the gear B is disposed at the bottom of the base plate; the gear B meshes with the gear A; the bottom of the gear B is fixedly connected to a mounting component; a servo motor B is fixedly disposed on the mounting component; the rotating shaft between the mounting components is connected to the servo motor B; and wheels are disposed between the bottoms of the mounting components.
[0010] Furthermore, the main body is provided with two sets; the servo motor A is provided with four sets; and the diameter of gear A is smaller than that of gear B.
[0011] Furthermore, the mounting mechanism also includes: a laser scanner;
[0012] The laser scanner is fixedly installed on the side of the main body; there are two sets of the laser scanner.
[0013] Furthermore, the servo motor B is provided in four sets; the wheels are provided in four sets; and the wheels are provided with anti-slip patterns.
[0014] Furthermore, the connecting mechanism includes: a connector and a fixing member;
[0015] The connector is located at the top of the main body; the fastener is fixedly located at the middle of the top of the connector.
[0016] Furthermore, the connecting mechanism also includes: an alarm light and a wind speed meter;
[0017] The alarm light is fixedly installed on the top of the connector; the anemometer is installed on both sides of the top of the connector; the top of the anemometer is provided with a hollow conical protrusion.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. This device includes gears A and B. Gear A is connected to the output shaft of servo motor A, while gear B is fixedly connected to the mounting component at the bottom. When turning is required, the servo motor A is controlled from the control panel to rotate gear A. The meshing of gears A and B further rotates gear B, causing the mounting component to deflect at a certain angle, thus achieving free turning. This makes the device more flexible and practical during movement, reduces the risks and costs of equipment relocation, improves equipment conversion efficiency, and ensures the safety of equipment relocation.
[0020] 2. This device is equipped with an anemometer and an alarm light. The anemometer is mounted on the connector, and the alarm light is also mounted on the connector. During use, the anemometer is rotated by the wind. Each rotation generates one or more pulse signals. By measuring the number of pulses (rotation speed) per unit time, the wind speed can be calculated. If the wind speed exceeds the limit, the alarm light will flash red and transmit the signal to the back-end system in a timely manner. The staff can then control the device to stop, ensuring safe production. Attached Figure Description

The gear A105 is used to drive the servo motor A104 to rotate, which in turn drives the gear B201 to rotate, thereby causing the mounting component 202 and the wheels 204 to deflect at a certain angle. The servo motor A104 is controlled synchronously by a background wireless controller.
[0032] The walking mechanism 2 includes: a gear B201; gear B201 is located at the bottom of the base plate 103; gear B201 meshes with gear A105; the bottom of gear B201 is fixedly connected to the mounting part 202; a servo motor B203 is fixedly mounted on the mounting part 202; the rotating shaft between the mounting parts 202 is connected to the servo motor B203; a wheel 204 is provided between the bottoms of the mounting parts 202; gear B201 is used to drive the mounting part 202 and the wheel 204 to rotate by meshing with gear A105, thereby realizing the steering function; the mounting part 202 is used to mount the servo motor B203 and the wheel 204; the servo motor B203 is used to achieve synchronous control through the background controller, and drives the rotating shaft on the mounting part 202 to rotate, thereby driving the wheel 204 to rotate; the wheel 204 has a load capacity of 15T and a speed of 0~100m / min.
[0033] Among them, such as Figure 2 As shown, the main body 101 has two sets; the servo motor A104 has four sets; and the diameter of gear A105 is smaller than that of gear B201.
[0034] Among them, such as Figure 2 As shown, the installation mechanism 1 also includes: a laser scanner 102; the laser scanner 102 is fixedly installed on the side of the main body 101; there are two sets of laser scanners 102; the laser scanner 102 here emits multiple laser beams, and generates a high-precision point cloud map of the surrounding environment by calculating the time of laser reflection, thereby identifying the outline, distance and even volume of obstacles, and transmitting the signal to the background controller.
[0035] Among them, such as Figure 2 As shown, there are four sets of servo motors B203; four sets of wheels 204; and anti-slip patterns are provided on the wheels 204.
[0036] Among them, such as Figure 1 As shown, the connecting mechanism 3 includes a connector 301 and a fixing member 302; the connector 301 is disposed on the top of the main body 101; the fixing member 302 is fixedly disposed at the middle position of the top of the connector 301; the connector 301 is used to connect the two sets of main bodies 101, while the fixing member 302 is used to fixally connect with the equipment to be used, such as a crane.

By measuring the number of pulses (rotation speed) per unit time, the wind speed can be calculated. If the wind force exceeds the standard, the signal can be transmitted to the backend for control. When the device is moving normally, the rotation of the anemometer 304 will not trigger an alarm because the device's movement speed is too slow to generate an alarm. The magnetoelectric sensor model here is set to 3300 XL NSv Series.
[0038] The specific usage and function of this embodiment are as follows:
[0039] In this invention, when the device needs to turn, the servo motor A104 is controlled by the backend to drive the gear A105 to rotate. The meshing of gears A105 and B201 further drives gear B201 to rotate, causing the mounting component 202 to deflect at a certain angle, thus achieving free turning. The servo motor B203 is also controlled by the backend to drive the wheel 204 to rotate, making the device more flexible and practical during movement. During operation, the laser scanner 102 detects obstacles and transmits signals to the backend. The wind speed meter 304 rotates, and the magnetoelectric sensor generates one or more pulse signals with each rotation. By measuring the number of pulses (rotation speed) per unit time, the wind speed can be calculated. If the wind speed exceeds the limit, the alarm light 303 will flash red and transmit the signal to the backend, allowing staff to stop the device and ensure safe production.
