[0002] In the production processes of industries such as environmental protection, metallurgy, industrial furnaces, chemicals, and building materials, materials can adhere to equipment surfaces, impacting production. Vibrating can effectively address this problem. Manual hammering is inefficient, labor-intensive, and extremely inconvenient. Furthermore, conventional mechanical vibrating devices are typically fixed point-to-point, and can only vibrate fixed points, not moving equipment, limiting their scope of use. Utility Model Content

[0003] The purpose of the utility model is to provide a rapping device, which can rappe fixed objects or movable objects, thereby improving production efficiency and reducing costs.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0005] A rapping device includes a power assembly, a rod body, a rapping hammer and an obstacle sensing assembly. One end of the rod body is fixed to the power assembly, and the rod body is driven to reciprocate by the power assembly. The other end of the rod body is fixedly connected to the rapping hammer, and the position of the rapping hammer corresponds to the rapping working surface; the obstacle sensing assembly is arranged close to the rod body, and the obstacle sensing assembly is used to monitor whether an obstacle causes position interference with the rod body.

[0006] Furthermore, the power assembly is a cylinder, and the rapping hammer is fixedly connected to the piston rod of the cylinder, and the rod body is driven to reciprocate by the extension or retraction of the piston rod.

[0007] Furthermore, the contact surface between the rapping hammer and the rapping working surface is at least one of a plane, a single-segment arc surface, a multi-segment arc surface, a sharp-angled surface and a serrated surface.

[0008] Furthermore, the obstacle sensing component includes a proximity sensor and a departure sensor respectively arranged on both sides of the rod body.

[0009] Furthermore, it also includes a controller, the power component and the obstacle sensing component are connected to the controller, and the controller is used to receive the sensing signal of the obstacle sensing component and control the power component to perform a response action based on the obtained sensing signal.

[0010] The unexpected beneficial effects of the present invention are as follows: the present invention drives the rod body to make reciprocating motion through the power component, and then drives the rapping hammer fixedly connected to the end of the rod body to make reciprocating motion, so as to achieve rapping of the rapping working surface at a preset frequency. In addition, an obstacle sensing component is arranged near the rod body. When it is applied to a motion device, the obstacle sensing component is used to monitor whether the obstacle on the rapping working surface has position interference with the rod body. When it is detected that there is position interference between the obstacle on the motion device and the rod body, the power component is used to drive the rod body to retract to avoid damaging the rod body; when it is detected that there is no position interference between the obstacle on the motion device and the rod body, the power component is used to drive the rod body to make reciprocating motion to vibrate the rapping working surface of the motion device. It can be seen that the rapping device described in the present invention can rap fixed objects or movable objects, thereby improving production efficiency and reducing costs.

[0017] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended solely to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0019] In one embodiment, see Figure 1 As shown, a rapping device is provided, comprising a power assembly 1, a rod 2, a rapping hammer 3, and an obstacle sensing assembly 4. One end of the rod 2 is fixed to the power assembly 1, and the rod 2 is driven to reciprocate by the power assembly 1. The other end of the rod 2 is fixedly connected to the rapping hammer 3, and the position of the rapping hammer 3 corresponds to the rapping working surface 6. The obstacle sensing assembly 4 is arranged close to the rod 2, and monitors whether an obstacle 7 interferes with the position of the rod 2 through the obstacle sensing assembly 4.

[0020] The utility model drives the rod body 2 to make reciprocating motion by a power module 1, and then drives the rapping hammer 3 fixedly connected to the rod body 2 end to make reciprocating motion, realizes rapping the rapping working surface 6 on the equipment at a preset frequency, and compared with manual hammering, significantly improves rapping efficiency. And by arranging an obstacle sensing component 4 near the rod body 2, when applied to a motion device, the obstacle 7 on the rapping working surface 6 is monitored by the obstacle sensing component 4 to determine whether position interference is generated between the rod body 2. When position interference is generated between the obstacle 7 on the motion device and the rod body 2, the rod body 2 is retracted by the power module 1 to avoid the obstacle 7 from damaging the rod body 2. When position interference is not generated between the obstacle 7 on the motion device and the rod body 2, the rod body 2 is driven to make reciprocating motion by the power module 1, and the rapping working surface 6 of the motion device is vibrated. As can be seen, the rapping device described in the utility model can rap fixed objects or movable objects, particularly can be applied to the rapping of movable objects, can solve the material adhesion problem by rapping without stopping the machine, improve production efficiency, reduce labor cost and time cost.

[0021] In a preferred embodiment, see Figure 2 As shown, the power assembly 1 is a cylinder, and the rapping hammer 3 is fixedly connected to the piston rod of the cylinder. The extension or retraction of the piston rod drives the rod body 2 to reciprocate.

[0022] A cylinder usually contains one or more pistons, which are pushed back and forth by gas pressure (usually compressed air) inside the cylinder, thereby driving a piston rod fixed to the piston to reciprocate.

[0023] The extension or retraction of the piston rod is directly controlled by changes in air pressure inside the cylinder. When the air pressure inside the cylinder increases, the piston and its connected piston rod will extend outward; conversely, when the air pressure decreases or is released, the piston rod will retract into the cylinder. Because the rapping hammer 3 is fixedly connected to the piston rod via the rod body 2, the rapping hammer 3 will also reciprocate accordingly as the piston rod extends or retracts. The reciprocating motion of the rapping hammer 3 can generate a powerful impact force or vibration force, which is used to remove dirt from the surface of an object, loosen attached materials, or perform other operations that require periodic impact force.

[0024] In a preferred embodiment, see Figure 3 As shown, the contact surface between the rapping hammer 3 and the rapping working surface 6 is at least one of a plane, a single-segment arc surface, a multi-segment arc surface, a sharp angle surface and a serrated surface. To adapt to different rapping requirements and application scenarios

[0025] The flat contact surface is simple and direct, suitable for situations where even distribution of impact force is required. It can provide a stable contact area during the rapping process, reduce local stress concentration, and is suitable for most standard rapping operations.

[0026] Single-segment curved surface: The single-segment curved surface design increases the curvature of the contact surface of the rapping hammer 3, making the rapping force more evenly distributed on the contact surface. It also helps to guide the direction of the impact force and reduce sliding or bouncing. This design is very useful when precise control of the rapping effect is required.

[0027] Multi-segment arc surface: Compared with the single-segment arc surface, the multi-segment arc surface has a more complex shape. It can guide the impact force in multiple directions, making the vibration effect more comprehensive and in-depth. It is suitable for occasions where complex surfaces or hard-to-reach corners need to be vibrated.

[0028] Sharp angled surfaces: Sharp angled surfaces concentrate impact force, generating significant pressure on a small contact area, making them suitable for applications requiring penetration or crushing of hard materials. However, this design can also lead to localized stress concentrations and requires caution to avoid damaging the rapping surface or the hammer.

[0029] Serrated Surface: The serrated surface design combines the concentrated impact force of a sharp angled surface with the multi-directional guidance characteristics of a multi-segment curved surface, generating a complex impact force pattern during vibration. This design is particularly effective when you need to quickly remove stubborn dirt or perform powerful crushing operations.

[0030] According to the specific rapping requirements and the characteristics of the rapping working surface, a suitable contact surface shape is selected. It should be noted that, in order to obtain the best effect, a combination of multiple shapes may be used to design the contact surface of the rapping hammer 3.

[0031] In a preferred embodiment, see Figure 1As shown, the obstacle sensing assembly 4 includes a proximity sensor 41 and a departure sensor 42 respectively arranged on both sides of the rod body 2. The proximity sensor 41 and the departure sensor 42 cooperate to achieve contact and separation monitoring of the obstacle 7.

[0032] See also Figure 4 As shown, when the rapping working surface 6 is at a speed V When moving to the left, the obstacle 7 on the rapping working surface 6 will move with the rapping working surface 6 until it contacts the proximity sensor 41. At this time, it is determined that there is position interference between the obstacle 7 and the rod body 2, and the power assembly 1 drives the rod body 2 to retract to prevent the obstacle 7 from damaging the rod body 2. Figure 5 As shown, as the rapping working surface 6 continues to move, the obstacle 7 will separate from the departure sensor 42. At this time, it is determined that there is no position interference between the obstacle 7 and the rod body 2, and the power component 1 drives the rod body 2 to move back and forth to vibrate the rapping working surface 6 of the moving equipment.

[0033] Each proximity sensor 41 and departure sensor 42 includes a bracket and a detection end rotatably connected to the bracket via a rotating shaft. When the proximity sensor 41 or departure sensor 42 is not in contact with the obstacle 7, the detection end is at an initial angle. When the proximity sensor 41 or departure sensor 42 comes into contact with the obstacle 7, the detection end rotates around the rotating shaft to a certain angle due to the interference of the obstacle 7. This simple structure makes it easy to determine whether the obstacle 7 is in contact with the proximity sensor 41 or departure sensor 42, thereby better controlling the operation of the rapping hammer 3.

[0034] In a preferred embodiment, see Figure 1 As shown, the rapping device also includes a controller 5, and the power component 1 and the obstacle sensing component 4 are connected to the controller 5. The controller 5 is used to receive the sensing signal of the obstacle sensing component 4 and control the power component 1 to perform a response action based on the obtained sensing signal.

[0035] By providing the controller 5 , the automatic operation of the rapping hammer 3 is achieved. Furthermore, the rapping frequency of the rapping hammer 3 can be set by the controller 5 .

[0036] For example, when the rapping working surface 6 is a fixed plane, the contact surface between the rapping hammer 3 and the rapping working surface 6 is set to a plane, carbon steel is used to manufacture the rapping hammer 3, the cross-sectional size of the rapping hammer 3 is 10×10 cm, and the hammering frequency is set to 20 times / minute.

[0037] When the rapping working surface 6 is an active surface and there is an obstacle 7 on the rapping working surface 6, the contact surface corresponding to the rapping hammer 3 and the rapping working surface 6 is set to a plane, carbon steel is used to manufacture the rapping hammer 3, the cross-sectional size of the rapping hammer 3 is 10×20 cm, and the hammering frequency is set to 10 times / minute.

[0038] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
