Description
Technical Field

[0002] The high beam of the leading vehicle of a train is also called the train headlight. The beam height of the train headlight is crucial to driving safety. Accurate beam height can ensure a good field of vision for the train driver at night or in low visibility conditions, and avoid the train failing to respond in time to obstacles on the road at night, in tunnels, and causing damage and loss to the safety of vehicles and passengers, while avoiding glare interference to oncoming vehicles; if the headlight beam is too low, it will reduce the illuminated area, and if the left and right offset of the beam exceeds the standard value, it will cause insufficient light intensity in front or too narrow visual range, affecting driving safety. Therefore, it needs to be adjusted and calibrated according to different project requirements before leaving the factory.
[0003] The current method for adjusting the train headlight beam is to use a bracket and a curtain. After the bracket is assembled at a specified position, the curtain is fixed on the bracket, and the headlight beam is received by the curtain for auxiliary adjustment. However, the curtain is made of flexible material. After the curtain is placed at a specified position, the angle adjustment of the curtain relative to the train front is generally only rough, and it is impossible to accurately ensure that the curtain and the train front are in a vertical state, resulting in a large error.

DETAILED DESCRIPTION
[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0031] Embodiment 1
[0032] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 3 As shown, a train headlight beam adjustment auxiliary receiving device includes a support leg 7, a pulley 8, a mounting plate 9 and a receiving plate 1.
[0033] like Figure 2 As shown, the tops of several legs are connected by a mounting plate 9, and the legs are provided with three groups to form a triangular leg, the top of the triangular leg is fixedly connected to the mounting plate and makes the mounting plate perpendicular to the horizontal plane, and the bottom of the leg is provided with a pulley, which is a universal wheel and is equipped with a locking mechanism to lock the pulley. The triangular leg enables it to achieve stable support for the receiving plate 1 through the mounting plate 9.
[0034] A set of mounting plates are fixed on the top of the three legs, and the plate surface of the mounting plate 9 is perpendicular to the horizontal plane. The receiving plate 1 is supported by the mounting plate.
[0035] In other examples, the length of the legs is adjustable to facilitate adjusting the height of the receiving plate. In this embodiment, the size of the receiving plate is sufficient to fit most vehicle models.
[0036] Since the train headlights are adjusted before leaving the factory, during adjustment, the pulleys of the three legs located on the side need to cooperate with the track, the distance between the pulleys on the two sides should be adapted to the track width, and the middle pulley is located in the middle of the rail, which can initially ensure that the receiving plate is located directly in front of the train.
[0037] like Figure 2 and Figure 3 As shown, a pair of ear plates 10 are provided on the front side of the mounting plate 9, and a through hole is provided on the ear plate 10; the ear plate 10 is arranged in the vertical direction; a lug is provided at the center position of the corresponding rear side of the receiving plate, and the thickness of the lug is adapted to the spacing between the pair of ear plates. When installing the receiving plate 1, the lug is inserted between the ear plates 10, and the fixing member passes through the ear plate 10 and the through hole on the lug. The fixing member 11 is a bolt, and after the bolt passes through the ear plate 10 and the lug, a nut is installed. By adjusting the tightness of the nut, the pitch angle of the receiving plate can be adjusted.
[0038] The receiving plate 1 and the mounting plate 9 of this embodiment are hinged. When the pitch angle of the receiving plate needs to be adjusted, the nut is loosened, the receiving plate 1 is rotated, and its pitch angle is adjusted. After the adjustment, the nut is tightened so that the ear plate presses the lug, thereby achieving relative fixation between the receiving plate 1 and the mounting plate 9, and completing the adjustment of the pitch angle of the receiving plate 1.
[0039] In other embodiments, the cooperation between the mounting plate 9 and the receiving plate 1 can refer to the movable connection structure between a computer monitor and a monitor bracket. Not only can the vertical pitch angle of the receiving plate 1 be achieved, but also the horizontal deflection angle of the receiving plate can be adjusted.
[0040] like Figure 1 As shown, the receiving plate is used to be mounted on the mounting plate and receive the projection point of the train headlight beam. Figure 1 It is a schematic diagram of the front side structure of the receiving plate, wherein a first slide groove 5 is provided at the bottom edge of the front side, a second slide groove 3 is provided at the top edge of the front side of the receiving plate, and a third slide groove 4 is provided on the vertical left side.
[0041] A laser rangefinder 2 is fixedly provided at the middle position of the first chute. By providing the laser rangefinder 2, the distance between the receiving plate and the train head can be measured.
[0042] Positioning members 6 are slidably arranged on the first slide slots 5 on the left and right sides of the laser rangefinder 2. The positioning members 6 are used to vertically fix the laser pen so as to adjust the receiving plate to be perpendicular to the train head through the laser beam emitted by the laser pen.
[0043] The sliding member includes a horizontal sliding member 13 slidably arranged on the top edge of the front side of the receiving plate and a vertical sliding member 12 slidably arranged on the vertical left side of the front side of the receiving plate. The horizontal sliding member 13 is slidably arranged on the second sliding groove 3, and the vertical sliding member is slidably arranged on the third sliding groove 4.
[0044] The sliding member includes a slider, which is engaged with the slide groove and slides together. A laser pen clamp is provided on the outer side of the slider, which is used to clamp the laser pen so that the axis of the laser pen is parallel to the receiving plate surface. The laser pen clamp on the horizontal slider and the vertical slider are perpendicular to each other. The laser beams emitted by the laser pens on the two sliders are perpendicular to each other and intersect at a point on the front side of the receiving plate. The intersection point is used as the fixed point position required by the technical requirements. By comparing the fixed point position required by the technical requirements and the projection point of the headlight beam, the train headlight can be adjusted.
[0045] The first slide groove 5, the second slide groove 3 and the third slide groove 4 of this embodiment are metal slide groove structures, and the slide grooves can be fixed on the edges of the receiving plate accordingly.
[0046] The sliders of the vertical slider 12 and the horizontal slider 13 are provided with a slot on the side that matches the slide slot, and a magnet is installed in the slot. The slider is installed on the slide slot through the magnet, which can realize the sliding match between the slider and the slide slot, and can also fix the slider in the specified position of the slide slot through the magnet. Figure 1 As shown, the vertical slide 12 and the horizontal slide 13 are respectively located at the middle position of the third slide groove 4 and the second slide groove 3. The intersection of the two laser beams can be used as the fixed point position required by the technology.
[0047] The structure of the laser pen clamping member on the sliders of the vertical slider 12 and the horizontal slider 13 can adopt a buckle structure, or other fixed clamping structure, as long as the laser pen can be clamped.
[0048] like Figure 1 As mentioned above, the laser pen clamping part on the vertical sliding part 12 needs to ensure that the axis direction of the laser pen fixed thereon is horizontal, in the same direction as the long side direction of the receiving plate 1. The laser pen clamping part on the horizontal sliding part 13 needs to ensure that the axis direction of the laser pen fixed thereon is vertical, in the same direction as the short side direction of the receiving plate 1, and the laser beams emitted by the two laser pens on the sliding part are perpendicular.
[0049] The receiving board 1 can be made of the same material as the classroom blackboard. After the laser beam hits the intersection, the point corresponding to the intersection can be marked on the receiving board 1 with chalk as a technical requirement for the fixed point position, so the laser pen does not need to be turned on continuously, but only needs to be turned on once.
[0050] Taking into account that when adjusting the train headlight beam, the adjustment standards are different due to different train models and the technical requirements for positioning are also different. A grid structure is provided on the front side of the receiving plate 1 of this embodiment, and the coordinates are marked to form a coordinate system, wherein the coordinates of the intersection of the first slide groove 5 and the third slide groove 4 are (0,0).
[0051] The manufacturer will formulate the distance between the receiving plate and the front of the vehicle, the corresponding technical requirements, fixed-point position coordinates and related standards and precautions according to different vehicle models. When adjusting, make adjustments according to the established standards.
[0052] like Figure 1 As shown, the structure of the positioning member 6 is the same as that of the sliding member, and the positioning member is also provided with a laser pen clamping member, and the positioning member 6 is provided with a group of the first slide grooves on both sides of the laser rangefinder. Unlike the sliding member, the axis of the laser pen clamping member on the positioning member 6 is perpendicular to the surface of the receiving plate. After the laser pen is installed on the positioning member, the light emitted by the laser pen is perpendicular to the surface of the receiving plate.
[0053] Through the laser pen on the two sets of positioning members 6 on the first slide 5, the receiving plate surface can be adjusted to be in a vertical state with the front of the train. The laser pen shoots the laser beam to the side of the front of the train, and a set of mirrors can be used to reflect the laser beam. It is necessary to ensure that the mirror is perpendicular to the side wall of the train and the mirror is perpendicular to the horizontal plane. The method of ensuring the verticality of the mirror can be achieved by using a corresponding right-angle bracket, which is a prior art. By emitting a laser beam and detecting the angle between the emitted beam and the reflected light, it is determined whether the receiving plate is perpendicular to the front of the train. When it is vertical, the emitted beam and the reflected beam are on the same straight line.
[0054] Two sets of positioning members 6 are provided for the purpose of adjusting the positions of the positioning members 6 laterally so that the spacing between the two sets of positioning members 6 is adapted to the width of the front of the train. The distances between the two sets of positioning members and the laser rangefinder should be equal to ensure that the receiving plate is located directly in front of the train. In addition, when the laser beam hits the outer side of the vehicle body, it can be determined whether the receiving plate is perpendicular to the front of the train by determining whether the beam is parallel to the corresponding horizontal mark on the vehicle body.
[0055] Two sets of positioning parts can realize measurement on both sides of the vehicle body. If the laser beam is parallel to the length direction of the vehicle body, it means that the receiving plate is perpendicular to the front of the vehicle. In addition, the pitch angle of the receiving plate can be determined by measuring the relationship between the height of the laser beam above the ground and the height of the laser beam transmitting end above the ground through the rolling teeth.
[0056] The laser rangefinder 2 can be used to determine the distance between the receiving plate 1 and the train. The laser pen on the positioning member 6 can be used to determine whether the receiving plate 1 is perpendicular to the train. The pitch structure of the receiving plate 1 can be adjusted to laterally deflect the structure to achieve overall adjustment of the receiving plate. After that, the fixed position required by the technical requirements is marked to adjust the train headlight beam.
[0057] The laser rangefinder of this embodiment can accurately measure the distance between the vehicle and the receiving plate 1. This is crucial to ensure the accurate projection of the light beam. The technical requirements for the distance between the vehicle and the receiving plate 1 of different models may be different. Without accurate distance measurement, it is difficult to ensure that the projection requirements of the light beam are consistent with the design technical requirements. The laser rangefinder 2 can measure the distance between the vehicle and the receiving plate 1 in real time, thereby achieving accurate adjustment of the receiving plate 1.
[0058] Through the marks produced by the horizontal laser beam and the vertical laser beam on the receiving plate 1, the adjuster can quickly and accurately measure the deviation of the headlight beam height from the fixed point position, so as to make precise adjustments. By projecting the beam onto the receiving plate 1 and comparing it with the fixed point position, the adjuster can quickly determine the direction and amplitude that need to be adjusted. This comparison method greatly improves the accuracy and efficiency of the adjustment and reduces the errors caused by inaccurate subjective judgment. It also reduces the inaccurate adjustment of the train headlight beam height and left and right cross adjustment caused by improper installation, placement and inaccurate marking of ordinary projection screens, as well as the waste of rework and repair.
[0059] It is understandable that when the train leaves the factory, the manufacturer configures a designated station for adjusting the headlights, so the corresponding ground is parallel to the horizontal plane. The corresponding train track is also straight.
[0060] In addition to improving the adjustment speed, the auxiliary receiving board can also improve the adjustment quality by using the device of this embodiment. Through precise projection and comparison, the adjuster can ensure that the light beam height meets the technical requirements and avoid being too high or too low. For example, if the light beam height is too high, it may cause glare interference to oncoming vehicles and affect driving safety; if the light beam height is too low, it may not provide sufficient lighting distance and affect the train driver's field of vision. The use of the auxiliary receiving board can help the adjuster accurately control the light beam height and improve the safety and comfort of train driving.
[0061] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 3 As shown, a train headlight beam adjustment method adopts any of the train headlight beam adjustment auxiliary receiving devices as described above, comprising the following steps:
[0062] Place the auxiliary receiving device in front of the train, use the triangular legs at the bottom to ensure that the receiving plate is stably placed, install the receiving plate, and lock the pulley. Turn on the laser rangefinder 2, and adjust the distance between the device and the train according to the laser rangefinder 2. Turn on the laser pen on the positioning piece, adjust the vertical state of the receiving plate and the front of the train, and then fix the receiving plate and the mounting plate.
[0063] The distance between the vehicle and the receiving plate 1 is monitored in real time by the laser rangefinder 2. The receiving plate is moved to the required position using a pulley according to the technical requirements so that the beam of the vehicle headlight can be effectively projected onto the receiving plate on the receiving plate. According to the intersection of the laser beams on the horizontal slide 13 and the vertical slide 12, the technical requirement fixed point position is determined and marked.
[0064] Turn on the train headlights and let the light beam project onto the receiving plate 1. Observe the landing point of the light beam on the receiving plate 1 and compare it with the fixed point position required by the technical requirements; based on the comparison results, determine whether the height of the train headlight beam needs to be adjusted. If adjustment is required, the height can be adjusted through the adjustment device or control system of the train headlight, while observing the changes in the light beam landing point on the receiving plate until the light beam height meets the technical requirements.
[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
