DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-2As shown, the utility model provides a technical solution, a device for preventing a chartered vehicle from reversing, comprising a chartered vehicle bottom plate 1, wherein the bottom of the four corners of the chartered vehicle bottom plate 1 are all equipped with chartered vehicle walking wheels 2, wherein an outer frame 15 is installed at the edge of the chartered vehicle bottom plate 1 of one of the chartered vehicle walking wheels 2, and the outer frame 15 is a detachable structure, and is installed inside thereof through a first outer frame connecting rod 13 and a second outer frame connecting rod 14, which can be convenient for later disassembly and maintenance, and a connecting plate pin shaft 8 is embedded and installed inside the outer frame 15, and a bracket connecting plate 7 is installed in the middle of the connecting plate pin shaft 8, and a wrench 9 is sleeved and installed at the outer end of the connecting plate pin shaft 8, and the wrench 9 is a hollow structure, which can better operate the wrench 9;

[0023] In order to facilitate better fixation, a plug rod positioning eye 11 is opened in the middle of the wrench 9, and a wrench plug rod 10 is embedded and installed in the side end of the outer frame 15 corresponding to the plug rod positioning eye 11, and the wrench plug rod 10 is L-shaped, which can facilitate better manual operation;

[0024] The bracket connecting plate 7 is connected to the inclined iron bracket 5 by the bracket screw 6, and the bottom end of the inclined iron bracket 5 is connected to the anti-backward inclined iron 3 by the positioning screw 4. In the normal state of the inclined iron bracket 5 and the anti-backward inclined iron 3, the anti-backward inclined iron 3 is parallel to the ground, and the edge of the anti-backward inclined iron 3 facing the chartered vehicle running wheel 2 is arc-shaped, so that the anti-backward inclined iron 3 can better fit the chartered vehicle running wheel 2;

[0025] The bracket screw 6 and the positioning screw 4 are both connected by screws and bolts, and the screws are full-thread screws, which are convenient for better adjustment and installation;

[0026] A spring 12 is sleeved on the outer side edge of the connecting plate pin shaft 8 , and the other end of the spring 12 is sleeved and connected to the outer side end of the first outer frame connecting rod 13 .

[0027] The working principle and use process of the utility model are as follows: during operation, first, the bottom plate 1 of the chartered vehicle is transported to the desired position, and then the wrench plug rod 10 is pulled out from the plug rod positioning eye 11. At this time, due to the tension of the spring 12, the wrench 9 is driven to reset. At this time, after the wrench 9 is reset, the position of the bracket connecting plate 7 is rotated to a horizontal state, so that the inclined iron bracket 5 moves up, so that the anti-retraction inclined iron 3 blocks the chartered vehicle walking wheel 2 to prevent it from moving;

[0028] When the bottom plate 1 of the chartered vehicle needs to be moved, the wrench 9 is turned to tilt the original bracket connecting plate 7, and then the wrench plug rod 10 is inserted into the plug rod positioning eye 11 to prevent the tension of the spring 12 from driving the wrench 9 to reset. At this time, the anti-retraction inclined iron 3 is away from the chartered vehicle walking wheel 2, so as to achieve normal movement;

[0029] During operation, the electric hydraulic lever can be controlled by remote control to drive the movement of the wrench 9, thereby realizing the limiting and moving operations.

[0030] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
