Description

Technical Field

[0001] The present invention belongs to the technical field of engineering equipment, and in particular relates to an engineering vehicle for bridge engineering maintenance. Background Art

[0002] Urban road and bridge construction is a relatively systematic project, especially when the construction conditions and construction sites are relatively complex, which makes bridge construction more difficult. However, road and bridge engineering is related to the convenience of people's travel and also has an important impact on the transportation industry. Not only does quality control need to be carried out during the early stages of construction, but the maintenance and repair of bridges during later use are equally important.

[0003] The bridge maintenance engineering vehicle is specially used for bridge disease detection and bridge maintenance; it can form an operating platform under the bridge and in inaccessible spaces, making bridge inspection and maintenance easier and more efficient.

[0004] However, the bridge maintenance vehicles currently in use are actually more of an auxiliary equipment, transporting people and objects to the bottom of the bridge or to spaces that are inaccessible without assistance, while the actual maintenance and inspection work still needs to rely on manpower and specialized equipment. In addition to the inspection of the bottom of the bridge, another important inspection project is the detection of cracks or hidden cracks in the bridge pavement. However, the maintenance engineering vehicles cannot detect and repair cracks or hidden cracks in the bridge pavement; equipment specifically for bridge cracks is also required for inspection; the operation of multiple devices will inevitably cause cross-influences and increase maintenance costs.

[0045] The support bracket 2 is connected to one side of the vehicle body 1; the upper side of the support bracket 2 is connected to the climbing frame mounting block 4 via a connecting mechanism 3; a climbing frame 5 is movably provided on the climbing frame mounting block 4 via an electric drive mechanism; under the action of the electric drive mechanism, the climbing frame 5 can be raised and lowered relative to the climbing frame mounting block 4; the climbing frame 5 can be raised when the vehicle is in motion or when it needs to be inspected and elevated.

[0046] A climbing drive mechanism 6 is installed at the lower end of the climbing frame 5, and the climbing drive mechanism 6 can move up and down on the climbing frame 5; an electric-controlled rotating mechanism 701 is provided at the lower end of the climbing drive mechanism 6, and the lower end of the electric-controlled rotating mechanism 701 is connected to one end of the extension arm 7, and the other end of the extension arm 7 is provided with a hanging basket 8; the electric-controlled rotating mechanism 701 drives the extension arm 7 to rotate; the climbing drive mechanism 6 can drive the extension arm 7 and the hanging basket 8 to move up and down; and adjust according to the position to be repaired;

[0047] A crack detection frame 9 and a filling sliding frame 11 are provided on the bottom surface of the vehicle body 1; a plurality of crack detection devices are provided on the crack detection frame 9 for detecting cracks in the bridge pavement;

[0048] A slide 12 is movably provided on the filling slide 11, and a filling feeding mechanism is connected to the slide 12; the slide 12 drives the filling feeding mechanism to move relative to the filling slide 11, and the filling material is released by the filling feeding mechanism to fill the crack;

[0049] The control unit is connected to the crack detection device, the slide 12 and the filling and conveying mechanism, and the slide 12 and the filling and conveying mechanism on the slide 12 are positioned and moved by the control unit.

[0050] Example 2

[0051] See Figure 2Based on Example 1, in order to maintain the balance of the vehicle body 1 and ensure safe operation, a chassis 201 is set on the vehicle body 1, one end of the chassis 201 is connected to the counterweight block 202, and the other end is connected to the lower end of the supporting frame 2; the counterweight block 202 can be used to balance the weight on the side of the climbing frame 5 to maintain the balance of the entire vehicle body 1.

[0052] Since the distance between the vehicle body 1 side and the side to be operated is different, and the climbing frame 5 needs to be as close to the vehicle body as possible to ensure safety during the driving process of the vehicle body, the connecting mechanism 3 is designed to be tilted and lifted to shorten the distance between the climbing frame 5 and the vehicle body 1, specifically including a connecting cross bar 301 and a hydraulic telescopic rod 302; among them, four connecting cross bars 301 are symmetrically arranged, two on each side of the upper and lower sides, and the two ends of the connecting cross bar 301 are respectively hinged to the supporting frame 2 and the climbing frame mounting block 4; the tail end of the hydraulic telescopic rod 302 is hinged to the supporting frame 2, and the telescopic end is hinged to the climbing frame mounting block 4; the hydraulic telescopic rod 302 extends, driving the connecting cross bar 301 to be lifted and tilted uniformly, thereby changing the distance between the climbing frame 5 and the vehicle body 1.

[0053] Example 3

[0054] See Figure 3-5 Based on Example 1, since the vehicle cannot cover the road surface laterally when traveling, it is impossible to perform crack scanning and detection with full coverage, so the crack detection frame 9 is set to an extendable structure, specifically including a first-level detection frame 901, a second-level detection frame 902, and a third-level detection frame 903; wherein the first-level detection frame 901 is connected to the lower bottom surface of the vehicle body 1; an electric-controlled slide rail 904 is provided on the upper top surface of the first-level detection frame 901 and the second-level detection frame 902; a telescopic slide groove 905 is provided on the second-level detection frame 902 and the third-level detection frame 903; the telescopic slide groove 905 is covered on the electric-controlled slide rail 904, and the second-level detection frame 902 is movably set in the first-level detection frame 901 and can be pushed out of the first-level detection frame 901 under the action of the electric-controlled slide rail 904; the third-level detection frame 903 is movably set in the second-level detection frame 902 and can be pushed out of the second-level detection frame 902 under the action of the electric-controlled slide rail 904; a plurality of laser scanning probes 10 are installed on the lower bottom surfaces of the first-level, second-level and third-level detection frames;

[0055] The road surface is tested by measuring the angle at which the laser beam reflects back to the reader. This distance signal is then subtracted from the accelerometer signal, eliminating the test vehicle's own vibrations and outputting a true road surface profile. The signal processing system converts the analog signal from the laser sensor into a digital signal and records it. The control unit then locates the crack, which is captured by the laser scanning probe 10 at position 9.

[0056] Example 4

[0057] See Figures 6-8As shown, after the crack position is located according to Example 1, it is necessary to track and fill the crack position, so the slide 12 on the filling slide 11 needs to have a positioning and tracking function; the filling slide 11 is an electric telescopic rod structure, and slideways 1101 are provided on both sides of the filling slide 11. The two pulleys 1203 of the slide 12 are installed on the slideways 1101 to realize the movement of the slide 12 on the filling slide 11;

[0058] The pulley 1203 is mounted on the upper end of the vertical rod 1202 of the slide 12, and the lower end of the vertical rod 1202 is mounted on the rotating end of the drive motor 1204. The telescopic crossbar 1201 is connected between the two drive motors 1204. The drive motor 1204 is controlled by a limit switch 1205, which is in turn controlled by the control unit. When the control unit locates a crack at the laser scanning probe 10 at position number 1, it controls the limit switch 1205. The limit switch 1205 controls the drive motor 1204 to drive the pulley 1203 to the corresponding point and then stop.

[0059] Since the widths of the telescopic sub-segments filling the slide frame 11 are slightly different, in order to ensure that the pulley 1203 of the slide 12 can always fit tightly against the slideway 1101, an adaptive structural design is made for the telescopic cross bar 1201. The fixed section of the telescopic cross bar 1201 is hollow inside, one end of the telescopic section is located inside the fixed section, and an elastic member 1206 is arranged between the telescopic section and the fixed section.

[0060] A filling material storage barrel 1302 is provided on the vehicle body 1 for storing crack filling raw materials.

[0061] The middle of telescopic crossbar 1201 is connected to a filling material discharge cylinder 1301, which is equipped with an electrically controlled valve. The upper end of this discharge cylinder 1301 is connected to one end of an elastic shrinkable material tube 13, the other end of which is connected to a filling material storage barrel 1302. When the slide 12 moves to a predetermined position, the control unit opens the electrically controlled valve, allowing the filling material to flow out.
