The top inner wall of the opening 1 3 is fixedly connected with an electric sheet 2 9, and the electric sheet 2 9 is adapted to the electric sheet 1 8. Before use, a communication transmitter is first installed on the tractor. Then, during use, when the tractor approaches the wheel block body 1, the information is transmitted to the communication receiving terminal 2 through the communication transmitter on the tractor, and then the information can be used to remind the driver through sound or light to avoid the tractor failing to accurately reach the designated position when moving. When the tractor moves onto the wheel block body 1, its tire rolls onto the pressing plate 12, pressing it downward to move the contact cylinder 7 downward, thereby separating the electric sheet 1 8 from the electric sheet 2 9.

[0023] In this embodiment, Figure 2 , Figure 6 and Figure 7As shown, a support plate 10 is fixedly connected to the side surface of the support ring 6, and two lower pressure plates 11 are fixedly connected to one side of the support plate 10, and a pressing plate 12 is fixedly connected to the opposite side of the two lower pressure plates 11, and the bottoms of the two lower pressure plates 11 are fixedly connected to a limiting ring 13, and the inner walls on both sides of the wheel block body 1 are movably connected with a transmission rod 14 through a bearing, and the outer wall of the transmission rod 14 is movably sleeved with a limiting plate 15, and one side of the limiting plate 15 is fixedly connected with a support plate 16, and the plug rod on the support plate 16 is sleeved inside the limiting ring 13, and the inner walls on both sides of the wheel block body 1 are respectively provided with a notch 17, and the bottom inner wall of the notch 17 is fixedly connected with a spring 18, and the plug rod on the support plate 16 is fixedly connected to the other end of the spring 18, and a movable groove 19 is provided on one side of the top of the wheel block body 1, and at the same time, pressing down the pressing plate 12 can make the lower pressure plate 1 on one side of it 1 moves downward, thereby pushing the insertion rod on the support plate 16 to move downward, and then through the transmission rod 14, the limit plate 15 is rotated upward at an angle, thereby limiting the movement of the tractor tire. When the tractor needs to be used, the information is first transmitted to the communication receiving end 2 through the communication transmitting end on the vehicle, so that the driving device 20 moves, and the stabilizing block 22 moves to both sides to separate it from the tire, and the tire moves out from the limit plate 15. Through the spring 15, the electric sheet 18 on the contact cylinder 7 moves upward and adapts to the electric sheet 29, and then through the spring 2 18, the support plate 16 can be ejected upward. When the tractor is separated from the wheel blocking device by a distance, the communication receiving end 2 cannot receive the information transmitted by the communication transmitting end, and the alarm device on the tractor will emit light or sound to remind the driver, so that the staff can collect the wheel blocking device.

[0024] In this embodiment, Figure 1 and Figure 3 As shown, a driving device 20 is fixedly connected to the inner wall of one side of the movable groove 19, a threaded rod 21 is fixedly connected to the transmission end of the driving device 20, and a stabilizing block 22 is movably connected to the outer wall of the threaded rod 21 through a thread. When the threaded rod 21 is separated, the driving device 20 is started to rotate the threaded rod 21. During the rotation, the stabilizing block 22 can be moved to both sides of the tractor tire to fit on the tire. The stabilizing block 22 has a plurality of protrusions on one side to increase its friction coefficient, thereby preventing the automobile tire from rotating.

[0025] The use method and advantages of the utility model: When the wheel chock reminder device is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, before use, a communication transmitter is first installed on the tractor, and then the wheel chock device is taken out of the tractor and placed next to the tire of the tractor. Then the tractor is started. When the tractor is close to the wheel chock body 1, the information is transmitted to the communication receiving end 2 through the communication transmitter on the tractor, and then the information can be used to remind the driver through sound or light to avoid the tractor being unable to accurately reach the designated position when moving. When the tractor moves onto the wheel chock body 1, its tire rolls onto the pressing plate 12, which is pressed down to move the contact cylinder 7 downward, so that the electric sheet 1 8 and the electric sheet 2 9 can be separated. At the same time of separation, the driving device 20 is started to rotate the threaded rod 21. During the rotation, the stabilizing block 22 can be moved to both sides of the tractor tire to fit on the tire. The stabilizing block 22 has a plurality of protrusions on one side to increase its friction, thereby preventing the car from being stuck. When the tire of the vehicle rotates, the pressing plate 12 is pressed down at the same time, so that the lower pressing plate 11 on one side can be moved downward, and then the insertion rod on the support plate 16 can be pushed downward, and then the transmission rod 14 is used to make the limit plate 15 rotate upward at an angle, thereby limiting the movement of the tractor tire. When the tractor needs to be used, the external drive device 20 is first started to move, and the stabilizing block 22 is moved to both sides to separate it from the tire, and the tire is moved out of the limit plate 15. Through the spring 15, the electric sheet 18 on the contact cylinder 7 is moved upward and adapted to the electric sheet 29, and then the support plate 16 can be ejected upward through the spring 2 18. When the tractor is separated from the wheel blocking device by a distance, the communication receiving end 2 cannot receive the information transmitted by the communication transmitting end, and the alarm device on the tractor will emit light or sound to remind the driver to collect the wheel blocking device.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
