Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 7, the bridge construction scribing apparatus provided by the embodiment of the invention includes a vehicle body 100 and a spraying device 200, wherein the vehicle body 100 can advance along a road, and a raw material box 102 is arranged on the vehicle body 100; the spraying device 200 includes a scribing hopper 230 and a scribing structure, the scribing hopper 230 is provided at the vehicle body 100 and is adjustable in a relative position to the vehicle body 100, and the scribing hopper 230 is used for receiving the raw material of the raw material tank 102 and transmitting the raw material to the scribing structure.
The scribing structure comprises a substrate 220 and two scribing rods 210, wherein the substrate 220 is arranged on a scribing hopper 230, the two scribing rods 210 are respectively arranged on two sides of the substrate 220, one end of each scribing rod 210 close to the substrate 220 is hinged with the substrate 220, the other end of each scribing rod is freely suspended, the hinged points of the two scribing rods 210 and the substrate 220 are symmetrically arranged about the center of the substrate 220, and the rod length of each scribing rod 210 is configured such that when the two scribing rods 210 are in the same straight line, the distance between the most distal ends of the two scribing rods 210 is equal to the bottom of a national standard arrow (the national standard arrow refers to an arrow of a travelling line on a road surface); two first driving members (not shown) are disposed on the base plate 220 to respectively drive the two scribing rods 210 to rotate. The scribing rod 210 is provided with a plurality of spray heads 211 at intervals along the length direction of the rod, the spray heads 211 are arranged in the middle of the substrate 220, and raw materials are sprayed from the spray heads 211 and scribed on the ground along with the travelling of the vehicle body 100.
according to the invention, by arranging the two mutually hinged scribing rods 210, the shape of the scribing rods 210 can be changed, so that pavement markers with various shapes can be integrally formed and drawn. For example, when a straight line needs to be drawn, the two scribing rods 210 are arranged in a V shape with the opening facing forward (the advancing direction of the vehicle body 100 is the front), the front ends of the scribing rods 210 are overlapped with the side edges of the straight line which needs to be drawn, the vehicle body 100 is pushed to advance to draw the straight line, the lining plates or the lining paper are padded at the front end and the rear end of the straight line which needs to be drawn, when the line is drawn, the front ends of the starting position scribing rods 210 are overlapped with the starting points of the straight line which needs to be drawn, the intersection points of the two scribing rods 210 are overlapped with the end points of the straight line which needs to be drawn at the end positions, and the lining plates or the lining paper can be taken away after the line is drawn, so that the standard straight line which remains on the ground can be ensured. For another example, when a straight arrow is required, according to the method of drawing a straight line, the vehicle body 100 moves forward to draw a straight line portion, when the vehicle body 100 moves to the junction of the straight line portion and the arrow portion at the front end of the scribing rod 210, the two scribing rods 210 are controlled to rotate reversely and expand simultaneously (i.e. the two scribing rods 210 swing in the direction away from each other so that the V-shape formed by the two scribing rods expands) along with the movement of the vehicle body 100 until the intersection point of the two scribing rods 210 moves to the junction of the straight line portion and the arrow portion, and the two scribing rods 210 are positioned in the same straight line and coincide with the bottom of the arrow; thereafter, as the vehicle body 100 continues to travel, the two scribing rods 210 are controlled to gradually approach each other, and the angle is adjusted from time to time, so that the ends of the two scribing rods 210 always advance along the oblique sides of the arrows, and finally, straight arrows are drawn by integral molding.
In a further embodiment, the discharge of each spray head 211 on the scribe bar 210 is inversely related to its distance from the substrate 220. It can be understood that, because the two scribing rods 210 are V-shaped and are closer to the substrate 220 during scribing, the closer the distance between the two nozzles 211 corresponding to the two scribing rods 210 in the scribing width is, the smaller the discharge amount of the nozzles 211 on the scribing rods 210 is from the substrate 220, and the larger the discharge amount of the nozzles 211 is from the substrate 220, so that the more uniform the overall scribing thickness can be ensured.
In a further embodiment, each scribing rod 210 includes a plurality of swing links 214 hinged to each other, the swing links 214 near the base plate 220 are hinged to the base plate 220, each swing link 214 can be controlled individually, and the spray heads 211 on the scribing rods 210 are disposed on the swing links 214 in a one-to-one correspondence.
Further, except for the front-end swing joint 214, the other swing joints 214 are provided with second driving members 212, the second driving members 212 are used for driving the previous swing joint 214 of the swing joint 214 where the second driving members 212 are located to rotate, and the swing joint 214 mounted on the base plate 220 is driven by the first driving members.
