Description

TECHNICAL FIELD

[0001] The present application relates to highway bridge construction equipment technology, in particular to a highway bridge construction equipment. BACKGROUND

[0002] In the process of highway bridge construction, road marking is an important link. Road marking refers to the use of lines, arrows, text, vertical signs, raised road signs and contour signs to convey guidance, restriction, warning and other traffic information to traffic participants. Its function is to control and guide traffic, which can be used in combination with signs or alone.

[0003] Before actual marking work, in order to make the marked line clear enough and the marking vehicle can advance stably in a straight line, it is necessary to arrange workers to clean the stones and other sundries on the road surface in advance. However, a small amount of fine stones may not be completely cleaned, and the remaining stones will still interfere with the advancing route of the marking vehicle during marking, resulting in inaccurate marking.

[0004] As disclosed in Chinese patent publication No. CN112342886A, a wheel-driven intermittent marking cart for bridge road marking is provided. The ordinary highway marking vehicle needs to manually control the length of the dashed line and the distance between the two adjacent dashed line units when marking the line. Compared with marking a solid line, marking a dashed line needs frequent switching, which consumes more labor and has low marking efficiency. The following solution is proposed, which includes a main vehicle body fixedly connected with a pair of push handles on one side of the upper end, a pair of front drive wheels and a pair of rear drive wheels fixedly connected to the lower end of the main vehicle body, and an intermittent material discharge mechanism fixedly connected to the lower end of the main vehicle body. The intermittent material discharge mechanism includes a material blocking plate, a pair of extrusion blocks and a pair of second metal expansion pipes. The invention realizes intermittent marking by setting an intermittent material discharge mechanism between the pair of rear drive wheels, and completes the marking operation of the dashed line by pushing the cart to make the rear drive wheels rotate, which is more convenient and faster, greatly improving the marking efficiency of the construction personnel.

[0005] In the above-mentioned solution, there is no structure to block the remaining stones after cleaning in the advancing direction of the marking vehicle. When there are stones in the advancing direction of the wheels, the wheels without blocking structure will directly roll over the stones, causing the whole vehicle body to shake and even deviate from the original route, resulting in inaccurate straight line marking.

[0032] In actual use, in the initial state, the stones on the road are preliminarily cleaned, and a small amount of fine stones cannot be completely cleaned; when the vehicle body 1 advances, the fixed brush 302 blocks the fine stones in the advancing direction of the front wheel 201, preventing the front wheel 201 from rolling over the fine stones, causing the vehicle body 1 to shake as a whole, or even deviating from the original route, resulting in inaccurate straight lines.

[0033] Further, please refer to Figures 5-6The transmission assembly comprises a first rotating rod 4 coaxially fixed with the front wheel 201, the first rotating rod 4 extends into the fixed frame 3 at one end away from the front wheel 201, the first rotating rod 4 is vertically fixed with an external gear 401 at the end extending into the fixed frame 3, the first rotating rod 4 is fixed with a connecting frame 403 on both sides close to the external gear 401, the connecting frame 403 is fixed with an internal gear 402 on the side away from the first rotating rod 4, the internal gear 402 rotates coaxially with the external gear 401, the external gear 401 and the internal gear 402 are incomplete gears, the external gear 401 and the internal gear 402 are in mesh transmission with a complete gear 501, the external gear 401 and the internal gear 402 are in intermittent mesh with the complete gear 501 respectively, the complete gear 501 is horizontally fixed with a second rotating rod 5, the second rotating rod 5 is rotatably connected with the outer side wall of the fixed frame 3, the second rotating rod 501 is fixed with a first pulley 502 at one end close to the outer side wall of the fixed frame 3, the fixed frame 3 is internally rotatably connected with a third rotating rod 6 on the side close to the front direction of the vehicle body 1, the third rotating rod 6 is vertically fixed with a second pulley 601 at both ends, the second pulley 601 and the first pulley 502 are in transmission connection through a transmission belt 503, and the third rotating rod 6 is in sliding fit with the cleaning assembly.

[0034] In actual use, when the vehicle body 1 advances, the front wheel 201 rolls forward, drives the first rotating rod 4 to rotate, drives the external gear 401 and the internal gear 402 to synchronously rotate, drives the complete gear 501 to reversely rotate intermittently, drives the first pulley 502 to reversely rotate intermittently, drives the second pulley 601 to reversely rotate intermittently through the transmission belt 503, and drives the third rotating rod 6 to reversely rotate intermittently, thereby driving the cleaning assembly to repeatedly move back and forth between the two sides of the fixed frame 3 in the process that the vehicle body 1 advances.

[0035] Further, referring to Figures 1-2 、 Figures 5-8 , the fixed frame 3 is internally horizontally provided with a first sliding groove 301 on the side close to the front direction of the vehicle body 1, the cleaning assembly comprises a movable brush 7, the movable brush 7 is perpendicular to the side of the fixed frame 3 close to the front direction of the vehicle body 1, the lower end of the movable brush 7 is in abutment with the ground, the movable brush 7 is fixed with a sliding block 701 on the side close to the fixed frame 3, the sliding block 701 is in sliding fit with the first sliding groove 301, the sliding block 701 is horizontally provided with a through hole 702, the third rotating rod 6 is in sliding fit with the through hole 702, the through hole 702 is horizontally fixed with a round rod 703 on the side wall, the third rotating rod 6 is provided with a spiral groove 601, the round rod 703 is in sliding fit with the spiral groove 601, and the movable brush 7 is in movable contact with the collecting assembly on both sides.

[0036] In actual use, the stones on the road are preliminarily cleaned in the initial state, and a small amount of fine stones cannot be completely cleaned. The movable brush 7 is located at the middle position outside the fixed frame 3. When the vehicle body 1 advances, the front wheel 201 rolls forward, driving the third rotating rod 6 to rotate. At this time, the round rod 703 slides in the spiral groove 602, driving the sliding block 701 to slide along the third rotating rod 6, driving the movable brush 7 to move along the first sliding groove 301 to both sides of the fixed frame 3, sweeping the fine stones blocked by the fixed brush 302 to both sides, avoiding the fine stones from being blocked by the fixed brush 302, and preventing the fine stones from passing through the blocking assembly to affect the normal straight-line advancement of the front wheel 201. Since the front wheel 201 drives the third rotating rod 6 to rotate forward and backward, the movable brush 7 repeatedly moves back and forth between the two sides of the fixed frame 3, and the fine stones blocked by the fixed brush 302 are swept to both sides of the fixed brush 302.

[0037] Further, please refer to Figures 1-4 、 Figures 9-10 The collecting assembly includes a collecting box 8 and a cover assembly for sealing the collecting box 8. The collecting box 8 is trapezoidal, and the side close to the movable brush 9 is an oblique edge opening. The cover assembly is in sliding fit with the outer surface of the opening of the collecting box 8, and is in movable contact with the movable brush 7. When the movable brush 7 presses the cover assembly, the cover assembly opens the collecting box 8. When the movable brush 7 is out of contact with the cover assembly, the cover assembly closes the collecting box 8.

[0038] Further, please refer to Figures 1-6 、 Figures 9-10 The side close to the fixed frame 3 of the collecting box 8 is fixed with two groups of clamping blocks 9. A limiting groove 902 is horizontally formed in the clamping block 9. A limiting block 901 is in sliding fit in the limiting groove 902. The bottom end of the limiting block 901 and the bottom end of the limiting groove 902 are elastically connected. The end of the limiting block 901 away from the limiting groove 902 and close to the fixed frame 3 is a bevel. The fixed frame 3 is fixed with two mounting seats 10 perpendicular to the fixed frame 3. Two groups of positioning notches 1001 are formed in the mounting seat 10. The limiting block 902 is in limiting fit with the positioning notches 1001.

[0039] In actual use, when the collecting box 8 needs to be installed, the clamping block 9 is inserted into the positioning notches 1001. The limiting block 901 is pressed into the limiting groove 902 until the limiting block 901 and the positioning notches 1001 are in mutual limiting fit, and the collecting box 8 is installed and fixed. When the collecting box 8 needs to be removed, the limiting block 901 is pressed into the limiting groove 902, the mutual limiting fit of the limiting block 901 and the positioning notches 1001 is cancelled, the collecting box 8 is pulled out in the direction away from the fixed frame 3, and the collecting box 8 is removed.

[0040] Further, please refer toFigure 1 Figures 9-10 The second sliding groove 801 is arranged on the side wall of the top end and the bevel opening of the collecting box 8. The cover assembly comprises a cover plate 802, which is a rubber soft plate. The cover plate 802 is in sliding fit with the second sliding groove 801 on both sides. The fixed block 804 is fixed at the top end of the collecting box 8. The first telescopic rod 805 is horizontally fixed on one side of the fixed block 804 close to the cover plate 802. The fixed rod 803 is fixed at the bottom end of the cover plate 802. The second telescopic rod 806 is fixed at one end of the fixed rod 803 close to the fixed block 804. The second telescopic rod 806 is in sliding fit in the first telescopic rod 805. The second telescopic rod 806 is elastically connected with the first telescopic rod 805. One end of the fixed rod 803 close to the movable brush 7 is in movable contact with the movable brush 7. When the movable brush 7 is in contact with and presses the fixed rod 803, the cover plate 802 opens the collecting box 8. When the movable brush 7 is out of contact with the fixed rod 803, the cover plate 802 closes the collecting box 8.

[0041] In actual use, in the initial state, the movable brush 7 is not in contact with the fixed rod 803, and the cover plate 802 is located at the bottom end of the second sliding groove 801, so that the cover plate closes the opening of the collecting box 8. In the process of advancing the vehicle body 1, the front wheel 201 drives the movable brush 7 to repeatedly move back and forth between the collecting boxes 8 on both sides of the fixed frame 3. When the movable brush 7 is in contact with and presses the fixed rod 803, the fixed rod 803 moves close to the fixed block 804, drives the second telescopic rod 806 to slide into the first telescopic rod 805, and drives the cover plate 802 to slide upward along the second sliding groove 801, so as to open the opening of the collecting box 8, and the movable brush 7 sweeps the small stones blocked by the fixed brush 302 into the collecting box 8, which is convenient for collection and cleaning. When the movable brush 7 moves in the opposite direction, the second telescopic rod 806 drives the fixed rod 803 to move away from the fixed block 804, drives the cover plate 802 to slide to the bottom end of the second sliding groove 801, and until the fixed rod 803 is out of contact with the movable brush 7, the cover plate 802 closes the opening of the collecting box 8, so as to prevent the small stones in the collecting box 8 from bouncing out of the opening in the process of advancing the vehicle body 1. Since the road surface has been preliminarily cleaned, the amount of small stones on the road surface is relatively small, and in use, the small stones in the collecting box 8 will not be filled up when the vehicle body 1 advances for a short distance, so as not to affect the normal use time of the device.

[0042] Further, please refer to Figures 1-4 The vehicle body 1 is fixed with a lime bucket 101 at the upper end. The vehicle body 1 is fixed with a spray head 103 below and in communication with the lime bucket 101. The vehicle body 1 is fixed with a push plate 102 at the upper end close to the rear wheel 102.

[0043] ​The working principle of the present application is: in the initial state, the stones on the road are preliminarily cleaned, and a small amount of fine stones cannot be completely cleaned, and the cover closes the opening of the collection box; when the vehicle body advances, the fixed brush blocks the fine stones remaining after cleaning in the forward direction of the front wheel to prevent the vehicle body from shaking or even deviating from the original route due to the fine stones being rolled by the wheels, causing the straight line drawn to be inaccurate, at the same time, the front wheel drives the first rotating rod to rotate, the first rotating rod drives the outer gear and the inner gear to rotate synchronously, the outer gear and the inner gear intermittently drive the complete gear to reverse, drive the first pulley to reverse, drive the second pulley to reverse through the transmission belt, thereby driving the third rotating rod to reverse, thereby driving the movable brush to move back and forth between the two sides of the fixed frame in the process of the vehicle body advancing, and the fine stones blocked by the fixed brush are swept to the two sides, avoiding the fine stones from being blocked by the fixed brush, which can affect the normal straight line advancement of the front wheel; when the movable brush approaches the collection box and contacts and presses the fixed rod, the fixed rod approaches the fixed block, drives the second telescopic rod to slide into the first telescopic rod, drives the cover to slide upward along the second sliding groove, opens the opening of the collection box, so that the movable brush sweeps the fine stones blocked by the fixed brush into the collection box, and the collection and cleaning are facilitated; when the movable brush moves in the opposite direction, the second telescopic rod drives the fixed rod away from the fixed block, drives the cover to slide to the bottom end of the second sliding groove, until the fixed rod is out of contact with the movable brush, and the cover closes the opening of the collection box, preventing the fine stones in the collection box from bouncing out of the opening during the advancement of the vehicle body, since the road has been preliminarily cleaned, the amount of fine stones on the road is relatively small, and in use, the problem that the collection box is filled with fine stones after the vehicle body advances for a short distance does not occur, and the normal use time of the device is not affected.
