[0021] An electric shovel is a bucket mounted on an excavator and is also called a digging bucket. It is a core piece of mining equipment in open-pit mines. Currently, electric shovels are usually exposed to the elements during daily use, and there is a lack of effective shielding measures after use. Due to the hard surface of the electric shovel, if it collides with people around it while it is not in use and is moving with the excavator, it can easily cause serious injury.

[0022] like Figures 1 to 3 As shown, this utility model provides an anti-collision device that can be fixed to the outside of the electric shovel 9 of an excavator. When the excavator moves with the idle electric shovel 9, it will move with the anti-collision device. If it accidentally collides with an object or a person, the impact intensity can be effectively eliminated through the protective mechanism of the anti-collision device, significantly reducing the damage to the object or person. The anti-collision effect is good.

[0023] This utility model anti-collision device includes a protective box 1, a drive mechanism, and a protective mechanism. The protective box 1 has a cavity 2 for accommodating the electric shovel 9 of an excavator. The drive mechanism is located at the bottom of the protective box 1, and the protective mechanism is located on the outside of the protective box 1. The drive mechanism has clamping plates 7 at both ends. The drive mechanism is designed to move the clamping plates 7 toward each other or away from each other to clamp or release the electric shovel 9, thereby protecting the outside of the electric shovel 9 and preventing the electric shovel 9 from directly colliding with objects or people and causing injury.

[0024] This utility model uses a drive mechanism to move the clamping plates 7 at both ends toward each other, thereby tightly clamping the electric shovel 9 placed in the cavity 2. After clamping, the entire anti-collision device can be fixed to the outside of the electric shovel 9. When the excavator moves with the idle electric shovel 9, it will move together with the protective box 1. If it accidentally collides with an object or a person, the elasticity and flexibility of the protective mechanism can effectively eliminate the impact intensity, significantly reducing the damage to the object or person. The anti-collision effect is good.

[0025] In one embodiment, the protective mechanism includes a crash barrier 10 and springs 11. The crash barrier 10 is disposed on the outside of the protective box 1, and the springs 11 are disposed between the crash barrier 10 and the outer wall of the protective box 1. In this embodiment, multiple springs 11 are provided between the crash barrier 10 and the protective box 1. The multiple springs 11 are evenly distributed in the height direction of the outer wall of the protective box 1. When any position of the crash barrier 10 is impacted, the impact force can be transmitted to the springs 11 through the crash barrier 10, and then the elastic deformation of the springs 11 absorbs part of the impact energy.

[0026] In this embodiment, the anti-collision plate 10 is U-shaped, mainly to buffer the impact force around the protective box 1.

[0027] In one embodiment, the outer wall of the anti-collision plate 10 is provided with a sponge pad 13. The sponge pad 13 is fixed to the outer wall of the anti-collision plate 10. When the anti-collision device accidentally collides with an object or a person, the outermost sponge pad 13 serves as the first flexible protective layer. It disperses the collision pressure and reduces the reaction force on the contact object through its own deformation, thereby reducing the damage to the collision object or person.

[0028] In one embodiment, the outer wall of the protective box 1 is provided with a damping pad 12, which corresponds one-to-one with the spring 11, and the spring 11 is fixed to the damping pad 12. The impact force can be attenuated by the frictional energy dissipation characteristics of the damping material of the damping pad 12, thus forming an effective buffer.

[0029] When the anti-collision device outside the electric shovel 9 accidentally collides with an object or a person, the anti-collision plate 10, located outside the protective box 1, first absorbs the impact force. After being compressed, the anti-collision plate 10 moves towards the protective box 1 and compresses the spring 11 fixedly installed on its inner wall. The spring 11 absorbs part of the collision energy through elastic deformation. At the same time, the damping pad 12 fixedly installed on the spring 11 contacts the outer wall of the protective box 1, and the frictional energy dissipation characteristics of the damping material of the damping pad 12 further attenuate the impact force, forming an effective buffer. The sponge pad 13 on the outer wall of the anti-collision plate 10, as the first flexible protective layer, disperses the collision pressure and reduces the reaction force on the contacting object or person through its own deformation. Through the triple protection of the flexible buffer of the sponge pad 13, the elastic energy storage of the spring 11, and the energy dissipation of the damping pad 12, the damage to the object or person caused by the collision can be significantly reduced, and the anti-collision effect is good.

[0030] In one embodiment, the driving mechanism includes a dual-axis motor 4, screws 5, and a slider 6. The dual-axis motor 4 is located at the bottom of the cavity 2. The two screws 5 are respectively connected to the two output ends of the dual-axis motor 4. The slider 6 is screwed onto the screws 5, and the clamping plate 7 is fixed to the slider 6. When the dual-axis motor 4 drives the screws 5 to rotate, the slider 6 moves on the screws 5, thereby driving the clamping plates 7 to move toward or away from each other.

[0031] In one embodiment, the dual-axis motor 4 is located at the bottom of the protective box 1. Grooves are provided on the inner walls of both sides of the protective box 1 near the bottom. The end of the screw 5 furthest from the dual-axis motor 4 is rotatably mounted within one of these grooves. In this embodiment, a bearing is installed within the groove, and the end of the screw 5 is mounted on the bearing. The grooves on the inner walls of the protective box 1 provide good support for the screw 5, ensuring its stability during use.

[0032] like Figure 2 As shown, in one embodiment, a guide rod 14 is fixed inside the protective box 1 along the extension direction of the screw 5, and the slider 6 is slidably connected to the guide rod 14. Specifically, a strip-shaped hole 3 is provided above the dual-axis motor 4 inside the protective box 1, the slider 6 is located inside the strip-shaped hole 3, and the guide rod 14 is provided inside the strip-shaped hole 3. The two ends of the guide rod 14 are fixed to the inner walls on both sides of the strip-shaped hole 3, and a sliding sleeve is fitted on the guide rod 14. When the dual-axis motor 4 drives the slider 6 to move, the slider 6 moves along the guide rod 14, which improves the stability of the slider 6 during the movement process. Moreover, the restriction of the slider 6 by the strip-shaped hole 3 can prevent the slider 6 from rotating during the movement.

[0033] In one embodiment, the clamping plates 7 are provided with anti-slip pads 8 on their sides facing each other. The anti-slip pads 8 are made of rubber material. The rubber anti-slip pads 8 can increase the friction between the clamping plates 7 and the electric shovel 9, thereby better fixing the protective box 1 to the outside of the electric shovel 9.

[0034] like Figure 3 As shown, in one embodiment, a stop block 15 is provided on one side of the clamping plates 7 facing each other. When the electric shovel 9 is housed in the protective box 1, the stop block 15 stops the top edge of the electric shovel 9. In this embodiment, the stop block 15 is provided on the top of the clamping plate 7 and is arranged in a right-angled triangle. One right-angled side of the stop block 15 is fixed to the inner wall of the clamping plate 7, and the other right-angled side blocks the top edge of the electric shovel 9. The stop block 15 provided on the inner side of the clamping plate 7 can block the top of the electric shovel 9 and prevent the electric shovel 9 from falling out of the protective box 1 due to vibration or other reasons, thus providing effective protection for the use of the anti-collision device.

[0035] In one embodiment, the bottom of the protective box 1 is provided with a plurality of casters 16, which enable the anti-collision device to move, for example, to the bottom of the electric shovel 9, or to be moved away from the bottom of the electric shovel 9, increasing the flexibility of the anti-collision device.

[0036] The process of using this anti-collision device is as follows.

[0037] When the excavator's electric shovel 9 is idle, the anti-collision device is moved under the shovel 9 using the casters 16. The excavator then controls the movement of the shovel 9, placing it inside the cavity 2 of the protective box 1. The dual-axis motor 4 is then activated, driving the screws 5 at both ends to rotate. These screws 5 cause the two sliders 6 to move towards each other, causing the clamping plates 7 fixed to the sliders 6 to move towards each other, tightly clamping the sides of the shovel 9. Once clamped, the anti-collision device is securely fixed to the outside of the shovel 9. Thus, when the excavator moves with the idle shovel 9, if it accidentally collides with an object or person, the protective box 1 outside the shovel 9 effectively prevents direct contact. Furthermore, the protective mechanism on the outside of the protective box 1 effectively absorbs the impact through elasticity and flexibility, thus reducing impact injuries. This effectively solves the problem of existing electric shovels 9 colliding with people when moving with the excavator after use due to the inconvenience of covering them, causing significant injury.
