Description

Technical Field

[0001] This utility model relates to the field of engine protection technology, specifically to a sensor anti-stepping device. Background Technology

[0002] The applicant's engine experienced a sensor breakage issue in the aftermarket. Disassembly of the failed component revealed that the sensor broke due to external mechanical damage. The reason for this external mechanical damage was that the sensor was located above the engine boundary and was easily subjected to external forces, especially during after-sales service, where it was prone to being stepped on, leading to sensor failure. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a sensor anti-trampling device that can effectively prevent physical damage and breakage of the sensor caused by external forces.

[0004] To solve the above-mentioned technical problems, this utility model provides a sensor anti-stepping device, including a zigzag-shaped anti-stepping plate. One end of the anti-stepping plate has a mounting hole, and the anti-stepping plate is fixed to the engine by bolts passing through the mounting hole. The other end of the anti-stepping plate extends upward and above the sensor. An anti-rotation block is provided on one end of the anti-stepping plate fixed to the engine. The anti-rotation block is used to abut against the engine's cooler bracket to prevent the anti-stepping plate from rotating during installation.

[0005] In some embodiments, the anti-stepping plate includes a fixed plate, a vertical plate, and a baffle connected in sequence. The mounting hole is opened on the fixed plate, the vertical plate is perpendicular to the fixed plate and the baffle, the height of the vertical plate is not less than the height of the sensor, and the baffle is used to block the sensor from above.

[0006] In some embodiments, reinforcing plates are provided between the fixed plate and the upright plate, and between the upright plate and the baffle.

[0007] In some embodiments, the upper surface of the baffle is provided with raised or reflective markings.

[0008] In some embodiments, the fixing plate, the upright plate, and the baffle are integrally formed structures.

[0009] In some embodiments, the bolt is fixed to the engine, and a nut is threaded onto one end of the bolt that passes through the mounting hole. A spring washer is provided between the nut and the anti-step plate.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model, by setting a zigzag anti-stepping plate structure, extends the baffle above the sensor to form a physical protective barrier, which can effectively prevent the sensor from being directly stepped on or collided with by external forces.

[0011] 2. This utility model prevents the anti-rotation plate from rotating during installation by abutting against the cooler bracket with the anti-rotation block, which facilitates installation. After installation, the anti-rotation plate just covers the sensor.

[0012] 3. By setting spring washers, this utility model can effectively resist the risk of loosening caused by long-term engine vibration, ensuring the continuous effectiveness of the protective device.

[0013] 4. This utility model enhances the connection rigidity between the fixing plate, the upright plate and the baffle by reinforcing plate to avoid deformation caused by stepping; at the same time, it allows the use of thinner plates, reducing the amount of material used and lowering costs while ensuring strength.

[0014] 5. This utility model provides raised or reflective markings on the upper surface of the baffle, which can effectively remind operators to pay attention and avoid it, further reducing the risk of accidental stepping. Attached Figure Description

[0017] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0018] like Figure 3 As shown, this utility model provides a sensor anti-stepping device, which is used to install on engine 7, which is a Dongfeng Cummins D6.7N gas engine. The sensor anti-stepping device is used to protect the EMP sensor.

[0019] like Figure 1As shown, the sensor anti-stepping device includes a zigzag-shaped anti-stepping plate 1. One end of the anti-stepping plate 1 has a mounting hole 111. The anti-stepping plate 1 is fixed to the engine 7 by bolts 4 passing through the mounting hole 111. The other end of the anti-stepping plate 1 extends upward and above the sensor 2. An anti-rotation block 14 is provided on one end of the anti-stepping plate 1 fixed to the engine 7. The anti-rotation block 14 is used to abut against the cooler bracket of the D6.7N gas engine to prevent the anti-stepping plate 1 from rotating during installation.

[0020] Specifically, such as Figure 1 As shown, the anti-stepping plate 1 includes a fixed plate 11, a vertical plate 12, and a baffle 13 connected in sequence. A mounting hole 111 is formed on the fixed plate 11. A bolt 4 is fixed to the engine 7. A nut 5 is threaded onto one end of the bolt 4 through the mounting hole 111. A spring washer 6 is placed between the nut 5 and the anti-stepping plate 1 to prevent loosening and avoid long-term vibration of the engine 7 causing the anti-stepping plate 1 to loosen. The vertical plate 12 is perpendicular to the fixed plate 11 and the baffle 13. The height of the vertical plate 12 is not less than the height of the sensor 2. The baffle 13 is used to block the sensor 2 from above.

[0021] The fixing plate 11, the upright plate 12 and the baffle 13 are integrally formed structures, and there is a smooth transition between the fixing plate 11, the upright plate 12 and the baffle 13.

[0022] To improve the rigidity between the fixed plate 11 and the upright plate 12, and between the upright plate 12 and the baffle 13, such as Figure 2 As shown, stiffening plates 3 are fixedly installed between the fixed plate 11 and the upright plate 12, and between the upright plate 12 and the baffle 13 by welding, to reduce the bending deformation between the fixed plate 11 and the upright plate 12, and between the upright plate 12 and the baffle 13 caused by stepping.

[0023] It is understandable that by setting the stiffening plate 3, the thickness of the fixing plate 11, the upright plate 12, and the baffle 13 can be reduced. Although the stiffening plate 3 is used, the overall material usage can still be reduced.

[0024] To further reduce the risk of trampling, raised or reflective markings can be installed on the upper surface of the baffle 13 to reduce the number of workers stepping on it.

[0025] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
