Description

Technical Field

[0001] This utility model belongs to the field of crane safety control technology, specifically relating to an anti-collision mechanism for a bridge crane. Background Technology

[0002] Bridge cranes are widely used in industrial production, but due to the complex operating environment, collisions between cranes or between cranes and surrounding obstacles occur frequently.

[0003] Existing crane anti-collision detection devices all require drilling holes in the crane's mounting beams, making the installation process cumbersome and difficult to adjust the position after installation. Chinese utility model patent CN218931511U discloses a crane anti-collision mechanism based on millimeter-wave radar detection, which uses a negative pressure chamber in conjunction with a suction cup to install the millimeter-wave radar sensor and alarm. However, this anti-collision mechanism has high requirements for the smoothness of the crane's steel plate surface. If the steel plate surface has oil stains, bumps, or rust, the suction force of the suction cup will decrease significantly or even fail. Furthermore, the silicone in the suction cup is easily corroded by ultraviolet rays or oil stains, leading to a decrease in sealing performance and causing the anti-collision mechanism to fall off.

[0004] Therefore, how to provide a bridge crane anti-collision mechanism that is less affected by the environment and whose installation position can be easily adjusted has become a problem that needs to be considered by those skilled in the art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model discloses an anti-collision mechanism for bridge cranes. This utility model has less requirement for the installation environment. By setting up an adjustable support mechanism and an elastic support mechanism, there is no need to drill holes in the installation beam, which facilitates the adjustment of the installation position. Moreover, it can realize the installation of the anti-collision mechanism on bridge cranes of different sizes.

[0006] To achieve the above objectives, the present invention specifically discloses the following solution:

[0007] A collision avoidance mechanism for a bridge crane includes a base, an elastic support mechanism, an adjustable support mechanism, a control mechanism, and a distance sensor. The elastic support mechanism is located on one side of the base, and the adjustable support mechanism is located on the other side of the base. The adjustable support mechanism includes a first L-shaped support leg, an adjusting screw, and an adjusting nut. Threaded holes are provided on both sides of the bottom of the base corresponding to the adjusting screw. One end of the adjusting screw is threaded into the base, and the other end of the adjusting screw is rotatably connected to the first L-shaped support leg. The adjusting nut is fixedly mounted on the adjusting screw near the end of the first L-shaped support leg. The control mechanism and the distance sensor are located on the surface of the base, and the distance sensor is electrically connected to the control mechanism.

[0008] Furthermore, the elastic support mechanism includes a sliding rod, a second L-shaped support leg, a linear bearing, a spring, and a limiting plate. The base has a cylindrical groove inside, the linear bearing is located at the opening of the cylindrical groove, the sliding rod extends into the cylindrical groove through the linear bearing, the limiting plate is located on the sliding rod extending into one end of the cylindrical groove, the spring is sleeved on the sliding rod, one end of the spring abuts against the limiting plate, and the other end of the spring abuts against the cylindrical groove.

[0009] Furthermore, it also includes a locking nut, which is threaded onto the adjusting screw and used to adjust the locking between the screw and the base.

[0010] Furthermore, the control mechanism includes a protective shell, a control circuit board, a buzzer alarm, and a power indicator light. The control circuit board is located inside the protective shell, while the buzzer alarm and power indicator light are located on the surface of the protective shell.

Detailed Implementation

[0018] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figure 1-2 As shown, this embodiment discloses an anti-collision mechanism for a bridge crane, fixed on the I-beam 17 of the bridge crane. It includes a base 1, an elastic support mechanism, an adjusting support mechanism, a control mechanism, and a distance sensor 16. The back center of the base 1 is hollowed out. The elastic support mechanism is located on one side of the base 1 and abuts against the upper flange of the I-beam 17. The adjusting support mechanism is located on the other side of the base 1 and abuts against the lower flange of the I-beam 17. The adjusting support mechanism includes a first L-shaped support leg 2, an adjusting screw 3, and an adjusting nut 4. Threaded holes are provided on both sides of the bottom of the base 1 corresponding to the adjusting screw 3. One end of the adjusting screw 3 is threaded into the base 1, and the other end is rotatably connected to the first L-shaped support 2. An adjusting nut 4 is fixedly mounted on the adjusting screw 3 near the first L-shaped support 2, used to adjust the extension length of the adjusting screw 3. To lock the adjusting screw 3 to the base 1, a locking nut 5 is also provided in this embodiment. The locking nut 5 is threaded onto the adjusting screw 3 and located at the connection between the adjusting screw 3 and the base 1. The control mechanism and the distance sensor 16 are mounted on the surface of the base 1. The distance sensor 16 is electrically connected to the control mechanism and is used to detect the distance to obstacles. This utility model, by setting an adjusting support mechanism, can adjust and adapt the size of different I-beams 17. The elastic support mechanism allows the spring 9 to press the I-beam 17 tightly, preventing the anti-collision mechanism from loosening.

[0021] The elastic support mechanism in this embodiment includes a slide rod 6, a second L-shaped support leg 7, a linear bearing 8, a spring 9, and a limiting plate 10. The base 1 has a cylindrical groove inside. The linear bearing 8 is located at the opening of the cylindrical groove. One end of the slide rod 6 is fixedly installed with the second L-shaped support leg 7, and the other end of the slide rod 6 extends into the cylindrical groove through the linear bearing 8. The limiting plate 10 is located on the slide rod 6 at the end that extends into the cylindrical groove. The spring 9 is sleeved on the slide rod 6. One end of the spring 9 abuts against the limiting plate 10, and the other end of the spring 9 abuts against the cylindrical groove.

[0022] The control mechanism includes a protective shell 11, a control circuit board, a buzzer alarm 12, and a power indicator light 13. The control circuit board is located inside the protective shell 11, while the buzzer alarm 12 and the power indicator light 13 are both located on the surface of the protective shell 11. The ranging sensor 16, the buzzer alarm 12, and the power indicator light 13 are all electrically connected to the control circuit board.

[0023] As a preferred embodiment of the present invention, it also includes a cover 14, which is rotatably disposed outside the ranging sensor 16. A locking bolt 15 is provided on the cover 14. When the installed I-beam is longitudinally arranged, causing the anti-collision mechanism to be installed longitudinally, the installation angle of the cover 14 can be rotated accordingly, so that the cover 14 is always above the ranging sensor 16.

[0024] In a preferred embodiment of the present invention, the outer surfaces of the first L-shaped support 2 and the second L-shaped support 7 are provided with anti-slip pads to improve the friction between the support and the flange.

[0025] In this embodiment, during installation, the extension length of the adjusting screw 3 is first changed so that the first L-shaped support 2 and the second L-shaped support 7 of the anti-collision mechanism are in contact with the upper and lower flanges of the I-beam 17. Then, the position of the anti-collision mechanism is adjusted. Once the position of the anti-collision mechanism is selected, the extension length of the adjusting screw 3 is increased so that the second L-shaped support 7 is gradually compressed. When the length of the slide rod 6 is contracted to the set range, the position of the locking nut 5 is adjusted so that it locks the adjusting screw 3, thus fixing the anti-collision mechanism.

[0026] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
