Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for construction equipment, and in particular to a collision warning device for construction equipment. Background Technology

[0002] In construction and road building projects, the operating environment for construction equipment (such as excavators, loaders, and road rollers) is complex, often surrounded by buildings, existing road surfaces, and various temporary facilities requiring protection. To reduce the risk of collisions between construction equipment and these protected objects due to operational errors or blind spots, the industry commonly uses warning devices around hazardous areas for safety reminders, with elastic bollard warning devices being particularly prevalent.

[0003] Elastic posts typically utilize their inherent elastic deformation capacity. When construction equipment approaches and comes into contact with them, the physical feedback (such as the shaking or deformation of the elastic post) provides visual or subtle tactile warnings to the equipment operators. However, construction sites are often characterized by high noise levels from engines and equipment operation. In such noisy environments, operators may find it difficult to detect a collision based solely on the conventional physical feedback (such as shaking) of the elastic post. If equipment fails to stop or adjust its trajectory after colliding with the elastic post, it could potentially cause more severe damage to surrounding buildings and roads, leading to property loss or even safety accidents. Therefore, we propose a construction equipment collision warning device to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the limited warning function of elastic posts and the inability to effectively provide secondary warnings to drivers after a collision. This invention proposes a collision avoidance warning device for construction equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction equipment anti-collision warning device includes a base, a rotating seat is provided on the base, a buzzer is provided on the rotating seat, and a mounting base is provided on the rotating seat.

[0007] A support base is installed inside the mounting base via a rotating shaft. A warning plate is provided at the upper end of the support base, and a lever is fixed at the bottom end of the support base.

[0008] It also includes support ear plates on both sides of the mounting base, with an arc-shaped guide rod fixed between the two support ear plates, and the arc-shaped guide rod passes through the aforementioned lever and slides with the lever;

[0009] The inner wall of the supporting ear plate is provided with a contact switch, and two pressure plates are slidably installed on the arc-shaped guide rod. The two pressure plates are located on both sides of the lever block, and springs are provided between the two pressure plates and the supporting ear plates on both sides.

[0010] Preferably, the warning plate is hollow and has a rhomboid cross-section. The rotating shaft is installed along the long diagonal of the rhomboid, so that when the warning plate is hit at different angles, it can more stably drive the rotating seat to rotate, thereby smoothly driving the mounting seat to rotate around the rotating shaft.

[0011] Preferably, the warning board is provided with multiple reflective strips, which are spaced apart along the height direction of the warning board to enhance the warning effect.

[0012] Preferably, the center of the circle containing the bending trajectory of the arc-shaped guide rod coincides with the center of the rotating shaft, so that the lever can rotate along the arc-shaped guide rod.

[0013] Preferably, the bottom end of the lever has a circular arc structure to prevent the rotating seat from interfering with the lever when it rotates.

[0014] Preferably, the contact switch is located on the movement trajectory of the toggle block, so that it can make contact with the toggle block during rotation, and the contact switch is electrically connected to the buzzer.

[0015] Preferably, the base is equipped with a storage battery, which is electrically connected to a contact switch and a buzzer.

[0016] Preferably, it also includes a protective outer shell covering the outside of the rotating seat, the outer shell having an opening for the warning plate to rotate, and the protective outer shell being made of rubber material, thereby protecting the interior of the rotating seat.

[0017] The beneficial effects of this utility model are as follows:

[0018] Compared with the prior art, this utility model uses a rotating seat in conjunction with the rotating warning plate. No matter from which angle the construction equipment collides with the warning plate, the warning plate can smoothly drive the toggle block to trigger the contact switch, realizing a secondary sound warning from the buzzer. This solves the problem that existing elastic columns are difficult to effectively remind the driver after a collision with construction equipment, thus improving construction safety.

[0022] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Reference Figure 1-2 A construction equipment anti-collision warning device includes a base 1, which provides a stable support foundation for the device and is used to fix it to the ground or other installation surfaces. A rotating seat 2 is provided on the base 1. The rotating seat 2 is mounted on the base 1 through a bearing. A buzzer 21 is provided on the rotating seat 2, and a storage battery is provided inside it.

[0024] The rotating seat 2 is provided with a mounting seat 3, which has a "U" shaped structure. A support seat 5 is installed inside the mounting seat 3 via a rotating shaft 4. The support seat 5 can rotate around the rotating shaft 4. A warning plate 6 is fixed to the upper end of the support seat 5, and a lever 8 is fixed to the bottom end of the support seat 5.

[0025] The warning plate 6 is hollow to reduce the overall weight. The cross-section of the warning plate 6 is rhomboid, and the rotating shaft 4 is installed along the long diagonal of the rhomboid. This allows the warning plate 6 to drive the rotating seat 2 to rotate more stably when it is hit at different angles, and thus smoothly drive the mounting seat 3 to rotate around the rotating shaft 4.

[0026] Secondly, multiple reflective strips 7 are provided on the warning board 6. The reflective strips 7 are spaced apart along the height direction of the warning board 6 to enhance the warning effect.

[0027] It also includes support ear plates 9 on both sides of the mounting base 3. The support ear plates 9 are located on both sides of the opening of the mounting base 3. An arc-shaped guide rod 10 is fixed between the two support ear plates 9. The arc-shaped guide rod 10 passes through the aforementioned lever block 8 and slides with the lever block 8. The center of the circle where the arc-shaped guide rod 10 bends coincides with the center of the rotating shaft 4, so that the lever block 8 can rotate along the arc-shaped guide rod 10. It should be noted that the bottom end of the lever block 8 is an arc structure to avoid the rotating base 2 interfering with the lever block 8 when it rotates.

[0028] A contact switch 13 is provided on the inner wall of the supporting ear plate 9. The contact switch 13 is located on the movement trajectory of the toggle block 8, which facilitates contact with the toggle block 8 during rotation. The contact switch 13 is electrically connected to the buzzer 21. Two pressure plates 11 are slidably installed on the arc-shaped guide rod 10. The two pressure plates 11 are located on both sides of the toggle block 8. Springs 12 are provided between the two pressure plates 11 and the two supporting ear plates 9. The springs 12 squeeze the two pressure plates 11 to clamp the toggle block 8, so that the warning plate 6 remains vertical in the natural state. After the warning plate 6 is released from collision, the springs 12 can automatically restore the device to its initial state, ensuring that the device can be reused and improving the practicality and durability of the device.

[0029] The base 1 is also equipped with a storage battery, which is electrically connected to the contact switch 13 and the buzzer 21 to supply power to the contact switch 13 and the buzzer 21.

[0030] Furthermore, it also includes a protective outer shell (not shown in the figure) covering the outside of the rotating seat 2. The outer shell has an opening for the warning plate 6 to rotate, and the protective outer shell is made of rubber material. The protective outer shell protects the inside of the rotating seat 2.

[0031] In this embodiment, the device is fixedly installed around the area to be protected in the construction site via the base 1. The warning board 6 is in a vertical and natural state. The pressure plate 11 is kept in its initial position under the elastic force of the spring 12. The contact switch 13 is in the open state. The buzzer 21 is not powered on.

[0032] When the construction equipment collides with the warning plate 6 from any angle, since the cross-section of the warning plate 6 is rhomboid and the rotating shaft 4 is installed along the long diagonal of the rhombus, the warning plate 6 can drive the rotating seat 2 to rotate on the base 1 regardless of the direction of the collision, adjust its posture to adapt to the collision angle, and at the same time rotate itself around the rotating shaft 4, and drive the toggle block 8 to rotate synchronously. The toggle block 8 pushes the pressure plate 11 to move along the arc trajectory (because the center of the circle where the arc guide rod 10 is located coincides with the center of the rotating shaft 4, it ensures that the movement trajectory of the pressure plate 11 matches the movement of the toggle block 8). When it rotates to the position of the contact switch 13, the pressure plate 11 triggers the contact switch 13. At this time, the circuit where the buzzer 21 is located is turned on, and the buzzer 21 emits an alarm sound to remind the construction equipment driver that a collision has occurred and that measures must be taken immediately to avoid secondary collisions or damage.

[0033] After the collision is resolved, spring 12 releases its elastic potential energy, pushing pressure plate 11 to move in the opposite direction along arc-shaped guide rod 10 to reset, causing toggle block 8 and warning plate 6 to return to their initial positions. Contact switch 13 disconnects, buzzer 21 stops alarming, and the device re-enters the standby state, constantly monitoring for the next possible collision.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
