[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way limits the present application and its applications or uses. Embodiment 1
[0025] The present application provides a self-adaptive track anti-off device for an aerial work platform, such as Figure 1 and Figure 2 as shown, comprising:
[0026] a base 1 fixed on the frame of the aerial work platform;
[0027] a track clamp 4 in sliding connection with the base 1, arranged above the track and maintaining a certain gap with the track;
[0028] a self-adjusting telescopic mechanism connected at one end with the base 1 and at the other end with the track clamp 4; for driving the track clamp 4 to slide up and down according to the force applied by the track to the track clamp 4 and the relative position between the frame and the track clamp 4, so that when the track clamp 4 is pressed by the track, the pressing force of the track on the track clamp 4 is controlled within a certain range; when the track clamp 4 is not pressed by the track, the track clamp 4 is automatically reset to the initial relative position with the track.
[0029] The self-adjusting telescopic mechanism includes a pressure sensor arranged on the track clamp 4, a distance sensor arranged on the base 1, and a controller (not shown in the figure), the pressure sensor is used to detect the pressing force of the track on the track clamp 4, the distance sensor is used to detect the distance between the track clamp 4 and the base 1, and the pressure sensor and the distance sensor are connected to the signal input end of the controller, and the signal output end of the controller is connected to the self-adjusting telescopic mechanism.
[0030] The present application transmits the distance between the track clamp 4 and the base 1 and the pressing force of the track on the track clamp 4 to the controller through the distance sensor and the pressure sensor respectively, and the controller controls the self-adjusting telescopic mechanism to drive the track clamp 4 to slide up and down, so that when the track clamp 4 is pressed by the track, the pressing force of the track on the track clamp 4 is controlled within a certain range; when the track clamp 4 is not pressed by the track, the track clamp 4 is automatically reset to the initial relative position with the track, thereby effectively avoiding the track off and avoiding the damage of the track due to excessive force. Embodiment 2
[0031] The embodiment is different from the embodiment 1 in that the self-adjusting telescopic mechanism comprises a telescopic cylinder 3, and the self-adaptive track preventing device in the embodiment further comprises a mounting frame 2, one end (fixed end) of the telescopic cylinder 3 is connected with the base 1, and the other end (telescopic end) of the telescopic cylinder 3 is connected with the track clamp 4 through the mounting frame 2.
[0032] In the initial state, a gap is kept between the track and the track clamp 4, and the distance between the base 1 and the top wall of the track clamp 4 is D at this time;
[0033] When the track encounters a ground protrusion, the track is bent under the force, and the track presses the track clamp 4, and when the pressing force exceeds or reaches a preset value X, the controller receives the signal transmitted by the pressure sensor and controls the telescopic cylinder 3 to retract, thereby driving the track clamp 4 to move upward, and the distance between the base 1 and the top wall of the track clamp 4 is reduced (less than D);
[0034] When the pressing force of the track on the track clamp 4 is greater than 0 and less than the preset value X, no damage is caused to the track, and the telescopic cylinder 3 is not moved at this time;
[0035] When the pressing force of the track on the track clamp 4 is 0 (the track is away from the track clamp 4 or just touches the track clamp 4 but does not exert force), if the distance detector detects that the distance between the track clamp 4 and the base 1 is less than D, it indicates that the gap between the track clamp 4 and the track is too large, and at this time, the distance sensor transmits a signal to the controller, and the controller controls the telescopic cylinder 3 to extend, thereby driving the track clamp 4 to move downward, and when the track clamp 4 is automatically reset to the initial relative position with the track, the telescopic cylinder 3 is no longer operated.
[0036] The self-adaptive track preventing device further comprises a sliding guide for guiding the sliding direction of the track clamp 4. In the embodiment, the sliding guide comprises a sliding groove arranged on the base 1, and the mounting frame 2 is slidably connected with the sliding groove through a sliding rail. The sliding groove is arranged in the vertical direction, thereby limiting the upward and downward sliding of the sliding rail, and ensuring the vertical movement of the sliding rail.
[0037] The application further provides a high-altitude operation vehicle, which is provided with the self-adaptive track preventing device. Embodiment 3

When the lower track is bent upward under force, the track contacts the rail clamp 4, the rail clamp 4 is driven to move upward under force, the spring in the self-adjusting mechanism is compressed, the rail clamp 4 is lifted upward, and the track is bent upward within the designed stroke; when the force of the lower track on the rail clamp 4 is less than the elastic force of the spring, the spring is elongated, and the rail clamp 4 is pushed back to the preset position
[0039] Through the structural design of the self-adaptive track anti-off device of the application, when the rail clamp 4 is pressed by the track, the pressing force of the track on the rail clamp 4 is controlled within a certain range; when the rail clamp 4 is not pressed by the track, the rail clamp 4 is automatically reset to the initial relative position with the track, thereby effectively avoiding track off and avoiding damage to the track due to excessive force.

For ordinary skilled in the art, the specific meaning of the above terms in the application can be understood through specific circumstances.
[0041] The above is only the preferred embodiment of the application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the application.
