Description

Technical Field

[0001] The utility model relates to the technical field of speed acquisition devices, and particularly relates to a device for acquiring the operating speed of mechanical equipment. Background Art

[0002] With the popularization of the Internet of Things, more data on linear or circular motion needs to be acquired at industrial sites. However, many original equipment devices usually do not install or do not fully install a speed measurement system, resulting in the inability to timely feedback the mechanical motion speed at industrial sites. Content of the Utility Model

[0003] The purpose of the utility model is to provide a device for acquiring the operating speed of mechanical equipment, so as to solve the problem that it is difficult to measure the speed of the original equipment device at present.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A device for acquiring the operating speed of mechanical equipment includes a base, a driving arm, a driven wheel and an encoder. The base is used to be fixed on the original equipment. One end of the driving arm is connected to the base. The driven wheel is rotatably arranged at the other end of the driving arm. The encoder is arranged at the other end of the driving arm and is coaxially arranged with the driven wheel. The driven wheel is used to contact the guide rail or wheel body of the original equipment to obtain frictional rotation, and then drive the encoder to rotate. The encoder is used to output a speed signal.

[0006] Further, an elastic abutting mechanism for driving the driven wheel to keep in contact with the guide rail or wheel body of the original equipment is arranged on the base.

[0007] Further, the elastic abutting mechanism includes a return tension spring and a connecting shaft. One end of the driving arm is rotatably arranged on the base through the connecting shaft. One end of the return tension spring is connected to the driving arm, and the other end is connected to the base.

[0008] Further, a first spring fixing hole is arranged at the lower part of the driving arm, and a second spring fixing hole is arranged at the bottom edge of the base.

[0009] Further, a plurality of first spring fixing holes are arranged, and the first spring fixing holes are arranged at intervals along the length direction of the driving arm.

[0010] Further, the base is L-shaped, and mounting holes for fixing on the original equipment are arranged at the bottom of the base.

[0011] Advantages of the Utility Model:

[0012] The device for collecting the operating speed of mechanical equipment of the present utility model can be fixed to the mechanical equipment to be monitored through the base. The driven wheel is installed at one end of the driving arm, so as to be in direct contact with the guide rail or the wheel body of the original mechanical equipment. Through the friction between the two, the driven wheel can rotate along with the movement of the mechanical equipment. The encoder is closely installed on the driven wheel to ensure that the two rotate coaxially. As the driven wheel rotates, the encoder can accurately capture and convert these mechanical movements into electrical signals, and then output them as speed data, thus facilitating the transformation of existing equipment, achieving accurate and stable monitoring of the operating speed of mechanical equipment, and providing strong support for data collection and monitoring in industrial sites.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0019] Figure 1 - Figure 3 As shown, the device for collecting the operating speed of mechanical equipment in this embodiment includes a base 1, a driving arm 2, a driven wheel 5 and an encoder 6. The base 1 is used to stably fix to the mechanical equipment to be monitored to provide a stable support. One end of the driving arm 2 is connected to the base 1, and the driven wheel 5 is installed at the other end of the driving arm 2, and its design purpose is to be in direct contact with the guide rail or the wheel body of the original mechanical equipment. Through the friction between the two, the driven wheel 5 can rotate along with the movement of the mechanical equipment. The encoder 6 is closely installed on the driven wheel 5 to ensure that the two rotate coaxially. As the driven wheel 5 rotates, the encoder 6 can accurately capture and convert these mechanical movements into electrical signals, and then output them as speed data.

[0020] To ensure that the driven wheel 5 can be in close and stable contact with the guide rail or wheel body of the original mechanical equipment, an elastic abutting mechanism is provided on the base 1. The elastic abutting mechanism includes a reset tension spring 4 and a connecting shaft 3. One end of the reset tension spring 4 is connected to the driving arm 2, and the other end is fixed on the base 1. The driving arm 2 is rotatably arranged on the base 1 through the connecting shaft 3. When the driven wheel 5 contacts the guide rail or wheel body, if the contact becomes loose due to vibration or other factors, the reset tension spring 4 will automatically adjust the angle of the driving arm 2 using its elastic force, thereby ensuring that the driven wheel 5 always maintains sufficient frictional force to achieve stable rotation.

[0021] To provide more flexible adjustment capabilities, a plurality of first tension spring fixing holes 7 for fixing the reset tension spring 4 are provided on the driving arm 2. The first tension spring fixing holes 7 are evenly distributed along the length direction of the driving arm 2, allowing users to select a suitable fixing position according to actual needs to adjust the pre-tightening force and tensile force of the reset tension spring 4. At the same time, corresponding second tension spring fixing holes 8 are also provided on the base 1 for firmly fixing the other end of the reset tension spring 4.

[0022] As Figure 2 and Figure 3 shown, the base 1 is designed in an L shape. This design not only provides sufficient installation area and stability for the device, but also facilitates users to fix it to the original mechanical equipment. Mounting holes 9 are provided at the bottom of the base 1, and users can use bolts, screws or other fasteners to firmly mount it on the mechanical equipment to ensure that the entire device will not loosen or fall off during operation.

[0023] Working principle:

[0024] When the mechanical equipment starts to operate, its guide rail or wheel body will drive the driven wheel 5 to rotate. Since the driven wheel 5 and the encoder 6 are coaxially installed, the rotor of the encoder 6 will also rotate with the rotation of the driven wheel 5. The sensors inside the encoder 6 will capture the rotational movement of the rotor and convert it into electrical signals (such as pulse signals). These electrical signals are then transmitted to external monitoring devices or control systems through data lines, and the real-time operating speed of the mechanical equipment can be obtained after processing.

[0025] In summary, the device provided by the present utility model realizes accurate and stable monitoring of the operating speed of mechanical equipment through its unique structural design and working principle, providing strong support for data collection and monitoring in industrial sites.

[0026] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.
