[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0025] like Figure 1 and Figure 2 As shown, a milling machine safety protection and anti-collision device provided by an embodiment of the utility model includes:
[0026] A fixing component, which is fixedly connected to the device, and a valve stem 05 is installed on the device; the fixing component includes:
[0027] A fixing plate 11, wherein the fixing plate 11 is fixedly connected to the device;
[0028] The slide cylinder 12 is fixedly connected to the fixed plate 11 , and a push assembly is slidably connected in the slide cylinder 12 . The setting of the fixed assembly ensures that the push assembly can slide stably in the slide cylinder 12 .
[0029] A pushing component, wherein the pushing component is slidably connected to the fixed component, one end of the pushing component protrudes from the device setting, and the other end of the pushing component abuts against the valve stem 05; the pushing component comprises:
[0030] A push rod 21, wherein the push rod 21 is slidably connected to the slide cylinder 12;
[0031] A contact head 22, the contact head 22 is fixedly connected to one end of the push rod 21, and is used to contact the obstacle 04;
[0032] The push head 23 is fixedly connected to the other end of the push rod 21 , and the push head 23 abuts against the valve stem 05 .
[0033] The spring 03 is arranged between the pushing component and the fixed component; when the pushing component is pushed by the obstacle 04, the spring 03 can be compressed and slide forward. At the same time, after the obstacle 04 is removed, the spring 03 can help the pushing component to reset.
[0034] In the embodiment of the utility model, when the milling machine is moving in reverse gear, if an obstacle 04 is encountered at the rear, the obstacle 04 will push the contact head 22, thereby causing the push rod 21 to slide in the slide cylinder 12. This action will cause the push head 23 to push the valve stem 05, thereby pushing the milling machine to the neutral gear or forward gear position, thereby preventing the equipment from continuing to move backward. Such a design can effectively avoid accidents that may be caused by the equipment continuing to move backward between the operator and the obstacle 04, greatly improving the safety of the operator.
[0035] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, a slide groove is provided in the slide cylinder 12, and the size of the slide groove is matched with the size of the push rod 21 to ensure that the push rod 21 can slide smoothly.

[0037] The working principle of the utility model is:
[0038] The safety protection and anti-collision device for the milling machine, when the milling machine is moving in reverse gear, if there is an obstacle 04 behind, the obstacle 04 will push the contact head 22, thereby causing the push rod 21 to slide in the slide cylinder 12. This action will cause the push head 23 to push the valve stem 05, thereby pushing the milling machine to the neutral gear or forward gear position, thereby preventing the equipment from continuing to move backward. Such a design can effectively avoid accidents that may be caused by the equipment continuing to move backward between the operator and the obstacle 04, greatly improving the safety of the operator.
