The importance of trackless transportation to high-yield and high-efficiency production and construction of modern mines is more and more prominent. However, the trackless rubber-tyred vehicle has poor road conditions during operation, and a roadway under a coal mine is narrow and dim in light. Because of the existence of gas in the underground coal mine, the car lamps of the trackless rubber-tyred vehicle adopt an explosion-proof structure, and because the car lamps of the trackless rubber-tyred vehicle in the prior art cannot synchronously rotate when the trackless rubber-tyred vehicle turns, therefore, when the body of the trackless rubber-tyred vehicle is not completely steered after the steering wheel of the trackless rubber-tyred vehicle rotates for a certain angle, the illumination in the advancing direction is greatly influenced, and because the driver's seat is arranged on the left side of the cab and the left front upright post of the cab, etc., the trackless rubber-tyred vehicle has larger blind areas in the left front and the lateral position, therefore, the arrangement of the front lamp in the prior art can easily cause the trackless rubber-tyred vehicle to collide with obstacles or other vehicles during running, easily cause scratch accidents and damage the vehicles, thereby greatly increasing the probability of car accidents, and influencing the personal safety and the coal mine safety production.

Detailed Description
(example 1)
Referring to fig. 1 to 5, the car light device of the trackless rubber-tyred car comprises an angle sensor 1, an acquisition control unit 2, a car light rotating mechanism 3 and 2 front car lights 5 arranged on the left and right.
The car light rotating mechanism 3 comprises an explosion-proof stepping motor 31, a driving gear 32, a rack 33, a first slot key 34, a first cotter pin 35, a left car light mechanism 36 and a right car light mechanism 37. The driving gear 32 is fixedly connected to an output shaft of the explosion-proof stepping motor 31. The rack 33 is in transmission connection with the pinion 32 and forms a rack and pinion mechanism. The output shaft of the explosion-proof stepping motor 31 is provided with a limiting hole at the upper end thereof, and a key groove is arranged at the connecting part with the driving gear 32. During installation, the driving gear 32 is circumferentially restrained by the first spline 34 engaging the corresponding output shaft spline. The first cotter pin 35 passes through the stopper hole of the output shaft to axially stopper the driving gear 32. The circumferential and axial limit enables the fixed connection between the driving gear 32 and the output shaft of the explosion-proof stepping motor 31 to be a detachable fixed connection.
The left lamp mechanism 36 and the right lamp mechanism 37 each include a lamp gear 41, a rotating shaft 42, a rotating base 43, a lamp holder 44, a bearing 45, a second slot key 47 of a fixed base 46, and a second split pin 48.
Each rotating shaft 42 is vertically arranged and forms a steel integrated piece together with the corresponding rotating machine base 43 positioned above, or both the rotating shafts and the corresponding rotating machine base are made of steel and are welded and fixed together. Each rotating shaft 42 is also rotatably coupled to a corresponding stationary housing 46 through a corresponding bearing 45, and each lamp gear 41 is fixedly coupled to a lower end of the corresponding rotating shaft 42. Wherein, each rotating shaft 42 is further provided with a limiting hole at the lower end thereof, and a key groove is provided at the connecting portion with the lamp gear 41. When attached, each second spline 47 is fitted into the spline groove of the corresponding turning shaft 42 to circumferentially limit the corresponding lamp gear 41. Each second cotter pin 48 passes through the position-restricting hole of the corresponding rotational shaft 42, thereby restricting the corresponding lamp gear 41 in the axial direction. This circumferential and axial spacing allows the fixed connection of each lamp gear 41 to the respective pivot shaft 42 to be a detachable fixed connection.
The lamp gears 41 are meshed with the racks 33 to be in transmission connection, and form corresponding gear-rack mechanisms.
The angle sensor 1 is an angle sensor with the model number of JG1008 of Changhui automobile electrical system (Anhui) limited, and the chip of the acquisition control unit 2 is a microcontroller with the model number of MC9S12XET256MAA of Feishikal. The sensor 1 is provided with an angle signal output end. The explosion-proof stepping motor 31 is provided with a control end. The acquisition control unit 2 is provided with an angle signal input end and a control signal output end. The angle signal output end of the angle sensor 1 is electrically connected with the angle signal input end of the acquisition control unit 2, and the control signal output end of the acquisition control unit 2 is electrically connected with the control end of the explosion-proof stepping motor 31.
The lamp holder 44 is detachably and fixedly connected to the rotating base 43. Each front lamp 5 is fixedly connected to a corresponding lamp holder 44. Thus, the lamp holder 44 can be directly replaced after being damaged without replacing the rotary base 43, so that the maintenance is very convenient.
The outer periphery of the bearing 45 is matched with the inner hole of the fixed base 46, and the inner hole of the bearing 45 is matched with the outer periphery of the rotating shaft 42. Therefore, only the bearing 42 is needed to be replaced after the bearing 45 is worn, and the fixed base 46 does not need to be replaced, so that the maintenance cost is lower.
Referring to fig. 5, when the vehicle lamp device of the present embodiment is used, the angle sensor 1 is mounted on the steering wheel 6 of the trackless rubber-tyred vehicle or on the steering tube under the steering wheel 6, and the base of the explosion-proof stepping motor 31, the acquisition control unit 2 and the fixed base 46 are all fixedly connected to the frame of the trackless rubber-tyred vehicle. The rack 33 is connected to the frame of the trackless rubber-tyred vehicle in a sliding manner. When the trackless rubber-tyred vehicle turns, the angle sensor 1 is driven to synchronously rotate along with the rotation of the steering wheel 6, and the angle sensor 1 sends out an angle change signal serving as a rotation signal. The acquisition control unit 2 receives the rotation signal of the angle sensor 2, calculates the rotation angle of the steering wheel 6, calculates the rotation angle required by the explosion-proof stepping motor 31, and sends a control signal to enable the explosion-proof stepping motor 31 to rotate according to the rotation angle required. The explosion-proof stepping motor 31 drives the driving gear 32 to rotate, the driving gear 32 drives the rack 33 to do linear motion, the rack 33 drives the 2 car light gears 41 to rotate, and the rotating shaft 42, the lamp bracket 44 and the front car light 5 which are sequentially and fixedly connected with each car light gear 41 synchronously rotate, so that the front car light 5 can irradiate the front of the trackless rubber-tyred vehicle quite clearly, and is not easy to collide with obstacles or other vehicles and scratch or rub during running and particularly turning, thereby greatly reducing the probability of car accidents, and being beneficial to personal safety and coal mine safety production.
