In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1 and 2, an embodiment of the present invention provides a DF12 type locomotive anti-delay system 10, wherein when the locomotive is delayed, the anti-delay system 10 can alarm to remind the driver to pay attention and take appropriate measures, so as to effectively prevent the delayed condition of the locomotive and protect the normal operation of the locomotive.
The anti-delay system 10 is mainly composed of a control module 11, a vehicle speed detection module 12 and a brake detection module 13.

In the anti-tarnish system 10, the control module 11 mainly receives three states of the locomotive: 1. whether the locomotive is in a loading state; 2. whether the speed of the locomotive is greater than 0; 3. whether the locomotive is braking. When the locomotive is in a loading state and the speed of the locomotive is greater than 0, the locomotive can send alarm information during initial braking, the alarm information can be displayed on an original display screen of the locomotive and also can be displayed through an audible and visual alarm, and the alarm information can prompt a driver that the locomotive has the possibility of delay and needs to be noticed.
In addition, when the running distance of the locomotive in the contracting brake state exceeds a preset distance threshold value, an alarm is given, wherein the preset distance threshold value can be 200m, 300m, 400m and the like.
The vehicle speed detection module 12 can detect the vehicle speed of the locomotive and feed back the vehicle speed information of the locomotive to the control module 11. The speed information of the locomotive is obtained from a locomotive speed sensor, is shaped after being isolated by a transformer, outputs two paths of signals, one path is a switching signal and indicates that the locomotive has a speed signal, and the other path is a pulse signal and is sent to a single chip microcomputer circuit, and the running distance of the locomotive after braking is calculated. The locomotive speed sensor and the locomotive speedometer are used in parallel, and can be a photoelectric speed sensor or a magnetoelectric speed sensor.
And the brake detection module 13 is used for detecting whether a brake shoe of the locomotive is loosened or not and feeding back brake shoe information to the control module 11. The brake shoe of the locomotive is released, which indicates that the locomotive is not braked, and the brake shoe of the locomotive is not released, which indicates that the locomotive is in a braking state.
The specific structure of the brake detection module 13 is as follows: brake detection module 13 comprises a brake cylinder and a proximity switch 131, proximity switch 131 being arranged on a piston rod of the brake cylinder and arranged to detect extension of the piston rod.
If the locomotive is relaxed, the proximity switch 131 outputs a low voltage signal; if the locomotive brakes, the proximity switch 131 outputs a high voltage signal.

The two fixing nuts 137 are fixed into a whole, the self-locking fixing piece 134 can be loosened only when the two fixing nuts 137 are rotated reversely by external force, and in the using process, the acting force generated by vibration, shaking and the like can only enable the two fixing nuts 137 to rotate towards the same direction generally (the existence of the left-handed thread and the right-handed thread can prevent the process), but the two fixing nuts 137 cannot rotate reversely, so that the two fixing nuts 137 are fixed into a whole, and the possibility of loosening the connecting piece 133 is further avoided.
Further, in order to facilitate the installation of the locking member 136, the adjacent ends of the two fixing nuts 137 may be gradually increased in diameter to the seating groove.
As an alternative to the above embodiment, opposite sides of the two fixing nuts 137 are provided with an annular groove and a plurality of spherical grooves, respectively, and the spherical grooves are provided with the balls 135 embedded therein.
