Description

Technical Field

[0001] The utility model belongs to the technical field of ship unloaders, and more specifically relates to an arm anti-collision laser installation structure. Background Art

[0002] When a ship unloader is operating at a port, its adjacent equipment may also be in operation. The adjacent equipment may be a gantry crane or other ship unloaders. In this case, the boom of the ship unloader is prone to collide with the adjacent equipment, causing an operational accident.

[0003] Based on this, some manufacturers began to install laser radar on the boom, using it to detect the surrounding environment and identify potential collision risks through real-time data analysis and processing. When the laser radar detects that the distance between the unloader boom or other objects is too close, the system will sound an alarm and take preventive measures, such as sending out sound signals or light signals, or even automatically stop the movement trajectory of the unloader to avoid collision.

[0004] However, the arm of the ship unloader is exposed. In rainy weather, too many water droplets adhere to the laser radar, which will affect the detection accuracy. In addition, the ship unloader continuously transports bulk materials, and the arm is always vibrating, which can easily damage the laser radar.

[0005] Therefore, it is necessary to propose a laser radar installation structure suitable for installation on the arm of a ship unloader. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0027] Reference Figures 1 to 4 As shown, a boom anti-collision laser installation structure is applicable to the boom of a ship unloader, comprising two brackets 1 fixed on the boom, the two brackets 1 are arranged at intervals in the horizontal direction, a crossbeam 2 is connected between the two brackets 1, a bearing plate 3 is provided on the side of the crossbeam 2 facing away from the boom, a laser radar 4 is fixed on the bearing plate 3, and a shock absorbing component 5 is connected between the laser radar 4 and the bearing plate 3 to reduce the influence of the vibration of the boom on the laser radar 4;

[0028] The protective cover 6 also includes a first plate body 61 and a second plate body 62 arranged at intervals from bottom to top, and a connecting plate 63 connecting the first plate body 61 and the second plate body 62, the connecting plate 63 is fixedly connected to the bracket 1, the first plate body 61 is located above the supporting plate 3, and a limiting hollow 611 is provided on the first plate body 61, and the laser radar 4 passes through the limiting hollow 611, and the second plate body 62 is located above the laser radar 4. The first plate body 61 is used to protect the laser radar 4 to prevent the laser radar 4 from being hit, and the second plate body 62 is used to block rain to prevent the rain from affecting the detection accuracy of the laser radar 4. In addition, the first plate body 61 and the second plate body 62 cooperate to have a shading effect, which can reduce the influence of light on the laser radar 4.

[0029] In this embodiment, a fixing plate 41 is provided on both sides of the laser radar 4, one end of the fixing plate 41 is fixedly connected to the laser radar 4, and the other end of the fixing plate 41 is connected to the supporting plate 3. The shock absorbing assembly 5 includes a shock absorbing pad, which is pressed between the fixing plate 41 and the supporting plate 3. The shock absorbing pad is used to reduce the vibration transmitted from the supporting plate 3 to the fixing plate 41, thereby reducing the impact on the laser radar 4.

[0030] Preferably, the fixing plate 41 is connected to the bearing plate 3 by screws, and the screws pass through the shock-absorbing pads, so when the screws are tightened, the shock-absorbing pads will be compressed, and one fixing plate 41 is fixed by two screws, so there are a total of 4 shock-absorbing pads, which are distributed in a matrix and can fully absorb vibrations.

[0031] In this embodiment, a plurality of slots 612 are provided at the edge of the position-limiting hollow 611, and elastic members 613 are embedded in the slots 612. The elastic members 613 are in contact with the laser radar 4, and the elastic members 613 are used to stabilize the laser radar 4 to prevent the laser radar 4 from shaking.

[0032] The elastic member 613 is provided with a slit, and the elastic member 613 is inserted into the slot 612 and clamped on the second plate 62 by the slit. Therefore, the elastic member 613 can be installed last and can be selected according to actual conditions. If the vibration amplitude of the arm is small, the elastic member 613 can be omitted.

[0033] Moreover, the elastic member 613 is softer than the shock-absorbing pad.

[0034] In this embodiment, the projection of the second plate 62 on the horizontal plane can cover the projection of the first plate 61 on the horizontal plane. Therefore, the second plate 62 can completely cover the first plate 61 to prevent rainwater from overflowing from the first plate 61 onto the laser radar 4.

[0035] Meanwhile, the second plate body 62 is semicircular in shape, and the arc side is located at the side of the second plate body 62 facing away from the bracket 1 , so as to prevent the second plate body 62 from being too sharp and hurting people.

[0036] In this embodiment, the distance between the second plate 62 and the laser radar 4 is 7-10 mm. At this distance, the shading effect is better and the structure is more compact.

[0037] In this embodiment, a reinforcing frame 7 is provided on the side of the second plate body 62 facing away from the laser radar 4 to improve the strength of the second plate body 62 and prevent the second plate body 62 from tilting.

[0038] Specifically, the reinforcing frame 7 includes a vertical plate 71 and a reinforcing plate 72. The vertical plate 71 is located on the side of the second plate body 62 close to the bracket 1. The reinforcing plate 72 is divided into a first horizontal section 721, an inclined section 722 and a second horizontal section 723 in the direction away from the bracket 1. The first horizontal section 721 is connected to the upper end of the vertical plate 71, and the second horizontal section 723 is connected to the second plate body 62. The reinforcing plate 72 cooperates with the vertical plate 71 to be arched upward, which can pull the second plate body 62 and effectively prevent the second plate body 62 from deforming and sinking downward.
