Detailed implementation manners

[0023] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0024] An embodiment of the present application discloses an anti-collision safety device for a road roller. Referring to Figure 1 , an anti-collision safety device for a road roller is provided at the front end and the rear end of the road roller, and it includes a base 1, a radar body 2 and a protective frame 3. The base 1 is installed on the road roller by bolts, the radar body 2 is embedded in the base 1, and the protective frame 3 is arranged on the base 1 along the circumferential direction of the base 1. And two opposite display screens 4 are fixed on the base 1, and the radar body 2 is located between the two opposite display screens 4. During the driving of the road roller, the radar body 2 monitors the obstacles on the driving path in real time, and at the same time cooperates with the display screens 4 to warn the pedestrians on the path, reducing the possibility of misjudgment or delayed judgment. And the protective frame 3 provides protection for the radar body 2 and the display screens 4, reducing the possibility of damage to the radar body 2 and the display screens 4, so that the radar body 2 and the display screens 4 can work more stably, thereby improving the safety of the road roller during use.

[0025] Referring to Figure 1 , a buzzer 5 is embedded in the base 1. When the detection value of the radar body reaches the activation threshold of the buzzer 5, the buzzer 5 is activated. The buzzer 5 provides a warning for pedestrians on the one hand and a warning for the driver on the other hand, further reducing the possibility of misjudgment or delayed judgment, thereby further improving the safety of the road roller during use. In the embodiment of the present application, the radar body 2 can be set as a radio frequency radar.

[0026] Referring to Figure 2 , in order to provide protection for the radar body 2, a protective shell 6 is detachably connected to the base 1, and the protective shell 6 covers the radar body 2.

[0027] Referring to Figure 2 and Figure 3, To facilitate the installation of the protective shell 6, the protective shell 6 is connected to the protective frame 3 through a connecting component 7. In the embodiment of the present application, the protective frame 3 and the base 1 are integrally formed.

[0028] The connecting component 7 includes a support plate 71, a connecting rod 72, and a spring 73. The support plate 71 is fixed to the side of the protective shell 6 close to the base 1. A connecting hole 61 is formed in the protective shell 6. The connecting rod 72 is slidably connected in the connecting hole 61. One end of the spring 73 is fixed to the connecting rod 72, and the other end is fixed to the support plate 71. A connecting groove 31 is formed in the protective frame 3. The end of the connecting rod 72 away from the support plate 71 extends into the connecting groove 31 and abuts against the bottom of the connecting groove 31. And the end of the connecting rod 72 away from the support plate 71 is set to be arc-shaped.

[0029] When the road roller is not in use, the worker snaps the protective shell 6 into the base 1. When the end of the connecting rod 72 contacts the protective frame 3, the connecting rod 72 retracts into the connecting hole 61, and at this time the spring 73 is in a compressed state. When the connecting rod 72 is opposite to the connecting groove 31, under the action of the resilience of the spring 73, the connecting rod 72 can be snapped into the connecting groove 31 and abut tightly against the bottom of the connecting groove 31. At this time, the installation of the protective shell 6 is completed, and the protective shell 6 abuts against the base 1, so that the protective shell 6 can provide protection for the radar body 2 more stably, reducing the possibility of the radar body 2 being affected by the harsh environment of the construction site and facilitating the subsequent continued use of the radar body 2.

[0030] Refer to Figure 3 , To facilitate the control of the connecting rod 72, a control hole 62 is formed in the protective shell 6. A control plate 621 is slidably connected in the control hole. The control plate 621 is fixed to the connecting rod 72. And a corrugated plate 622 is arranged in the control hole 62. One end of the corrugated plate 622 is fixed to the inner wall of the control hole 62, and the other end is fixed to the control plate 621.

[0031] A support rod 711 is fixed to the support plate 71. A support groove 721 is formed on the side of the connecting rod 72 close to the support plate 71. The support rod 711 is slidably connected to the inner wall of the support groove 721. The connecting rod 72 and the support rod 711 cooperate to provide support for the connecting rod 72 and improve the stability of the connecting rod 72 during movement.

[0032] When it is necessary to remove the protective shell 6, the worker pulls the control plate 621. The control plate 621 drives the connecting rod 72 to move, so that the connecting rod 72 is separated from the connecting groove 31. At this time, the worker moves the protective shell 6 in the direction away from the base 1, and the protective shell 6 can be removed, thus facilitating the disassembly of the protective shell 6. At the same time, the corrugated plate 622 shields the control hole 62, reducing the possibility of sand and gravel on the construction site entering the protective shell 6 and further improving the protection ability of the protective shell 6 for the radar body 2.

[0033] Reference Figure 2 Figure 2 , the connecting components 7 are provided in two sets that are oppositely arranged to improve the connection stability between the protective shell 6 and the protective frame 3. And in order to facilitate the storage of the protective shell 6, two opposite support blocks 8 are fixed on the base 1, and each support block 8 corresponds to a connecting rod 72 in a set of connecting components 7, and a relief groove 81 that matches the connecting rod 72 is formed on the support block 8. After the protective shell 6 is removed, the worker places the protective shell 6 between the two support blocks 8. At this time, the connecting rod 72 is snapped into the relief groove 81 to limit the protective shell 6.

[0034] Reference Figure 3 Figure 3 , and a sealing gasket 63 is fixed on the side of the protective shell 6 close to the base 1, and the sealing gasket 63 abuts against the base 1. The sealing gasket 63 improves the sealing ability between the protective shell 6 and the base 1, reduces the possibility that external sand and gravel enter the protective shell 6 through the gap between the protective shell 6 and the base 1, and thus further improves the protection ability of the protective shell 6 for the radar body 2.

[0035] Reference Figure 1 and Figure 4 Figure 4 , a water collecting groove 11 is formed on the protective frame 3, a water draining hole 12 is formed at the bottom of the water collecting groove 11, and a filter screen 13 is arranged in the water draining hole 12. The water collecting groove 11 cooperates with the water draining hole 12, so that rainwater during rainy days is not likely to accumulate in the protective frame 3 and affect the radar body 2. At the same time, the filter screen 13 reduces the possibility of blockage of the water draining hole 12.

[0036] The implementation principle of the anti-collision safety device for a road roller in an embodiment of the present application is as follows: during the driving process of the road roller, the radar body 2 detects obstacles on the driving path in real time, and at the same time, the display screen 4 continuously displays warning words, so that people on the path can more intuitively observe the driving path of the road roller. At the same time, the protective frame 3 provides protection for the radar body 2 and the display screen 4, reducing the possibility that flying sand and gravel during the driving process of the road roller damage the radar body 2 and the display screen 4, so that the radar body 2 and the display screen 4 can work more stably, thereby improving the safety during the use of the road roller.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
