Description

Technical Field

[0001] The invention relates to the technical field of bridge inspection vehicles, in particular to a bridge inspection vehicle and a turnover bracket thereof. Background Art

[0002] The bridge inspection vehicle is a special vehicle that can provide a working platform for bridge inspectors during the inspection process, equipped with bridge inspection instruments, and used for mobile inspection and maintenance operations. It can efficiently allow inspectors to enter the working position for mobile inspection or maintenance operations, greatly improving the efficiency of bridge inspection and maintenance. It can be moved at any time, and can safely, quickly and efficiently allow inspectors to enter the working position for mobile inspection or maintenance operations. It does not affect traffic during work and can travel slowly without retracting the boom. The working principle is that the hydraulic system bends the working arm deep into the bottom of the bridge to inspect the bridge. It is composed of a car chassis and a working arm. According to the different special working devices, bridge inspection vehicles are mainly divided into two types: hanging basket type and truss type.

[0003] When the truss bridge inspection vehicle is in use, the inspection personnel can easily enter the platform or return to the bridge deck from the bridge deck, and the personnel can walk in the flip aisle bracket, and the flip aisle bracket is also connected to a retractable telescopic aisle bracket. By extending the telescopic aisle bracket, the inspection and maintenance range of the bridge by the maintenance personnel is improved; but the existing telescopic aisle bracket can only be extended and retracted in a straight line, and the maintenance personnel can only inspect the parts of the bridge in the same straight line position. If inspection of other positions is required, the flip aisle bracket needs to be rotated. Since the flip aisle bracket is long, a small rotation angle will result in a large position change, and the position after rotation is difficult to control, and the inspection range is also limited, which is a little inconvenient when used. Summary of the invention

[0031] like Figure 6-7 As shown, the rotating mechanism 3 includes a fixed seat 301, which is fixedly connected to the end of the flip aisle bracket 1, and the fixed seat 301 is fixed to the lower surface of the flip aisle bracket 1. The upper surface of the fixed seat 301 is rotatably connected with a rotating platform 302, and the rotating platform 302 is flush with the bottom plate of the flip aisle bracket 1 to avoid interference with the movement of the telescopic aisle bracket 2. The telescopic aisle bracket 2 is extended along the end of the flip aisle bracket 1 and then connected to the rotating platform 302; the rotating platform 302 is an arc-shaped structure, and a limit plate 303 matched with the rotating platform 302 is fixedly connected to the upper surface of the fixed seat 301; the limit plate 303 is flush with the upper surface of the rotating platform 302, and the limit plate 303 is provided with an arc groove matched with the arc surface of the rotating platform 302, which plays a stabilizing role when the rotating platform 302 rotates, and a pair of supports 304 are symmetrically provided on the rotating platform 302, and the supports 304 are respectively provided on both sides of the telescopic aisle bracket 2.

[0032] A disc is provided on one side of the rotating platform 302, and a rotating shaft is fixedly connected to the disc. The rotating shaft is rotatably connected to the fixed seat 301 through a bearing, and a driving mechanism 4 for driving the rotating platform 302 to rotate is provided on the lower surface of the fixed seat 301. The driving mechanism 4 includes a rotating motor 401, and the driving motor 401 is installed on the lower surface of the fixed seat 301 through a mounting frame. A gear 402 is connected to the rotating motor 401, and a toothed disc 403 is connected to the rotating shaft of the rotating platform 302. The gear 402 is meshed with the toothed disc 403. The diameter of the toothed disc 403 is much larger than the diameter of the gear 402, which has a deceleration effect and ensures the slow rotation of the telescopic aisle bracket 2.

[0033] like Figure 8 As shown, a groove 3044 is provided on the support 304, and a socket 3045 is provided on the inner wall of the groove 3044 and passes through the support 304; both end sides of the telescopic aisle bracket 2 are fixedly connected with an insertion rod 202 that cooperates with the socket 3045; when the telescopic aisle bracket 2 is extended, the insertion rod 202 at one end of the telescopic aisle bracket 2 is inserted into the socket 3045, so that the telescopic aisle bracket 2 is stably connected to the rotating platform 302; when the telescopic aisle bracket 2 is retracted, the insertion rod 202 at the other end of the telescopic aisle bracket 2 is inserted into the socket 3045; a limiting groove 3041 that is slidably matched with the limiting slide 201 is provided on the support 304, and a driving wheel 3042 for driving the telescopic aisle bracket 2 to move is rotatably connected in the limiting groove 3041, and the driving wheel 3042 is in contact with the side of the limiting slide 201, A driving motor 3043 for driving the driving wheel 3042 to rotate is installed on the support 304. The driving motor 3043 can drive the driving wheel 3042 to rotate by gear meshing. When the driving wheel 3042 rotates, it drives the telescopic aisle bracket 2 to move, thereby completing the extension and contraction of the telescopic aisle bracket 2. A block 308 for limiting the rotation angle of the rotating platform 302 is fixedly connected to the fixed seat 301, wherein the rotation angle of the rotating platform 302 is set between 0-90°, and the rotating platform 302 can rotate to both sides. A pair of guide wheels 307 are symmetrically connected to the rotating platform 302 for rotation. The two guide wheels 307 are symmetrically arranged on both sides of the telescopic aisle bracket 2, and the guide wheels 307 are in contact with the surface of the limiting slide plate 201, thereby playing a role in guiding and limiting the telescopic aisle bracket 2.

[0034] Preferably, in order to ensure the stability of the telescopic aisle bracket 2 when it is extended onto the rotating platform 302, a pair of reinforcing plates 305 for supporting the telescopic aisle bracket 2 are symmetrically fixedly connected to the rotating platform 302, and a limiting frame 306 cooperating with the limiting slide plate 201 is fixedly connected to the reinforcing plate 305, and the limiting frame 306 is an inverted L-shaped structure.

[0035] like Figure 2 and Fig. 9 As shown, after the telescopic aisle bracket 2 is extended, the maintenance personnel standing on the telescopic aisle bracket 2 will increase the weight of the telescopic aisle bracket 2. In order to ensure the stability of the connection between the telescopic aisle bracket 2, the rotating platform 302 and the flip aisle bracket 1, an elastic stretching mechanism 5 is connected between the flip aisle bracket 1 and the fixed seat 301. The number of the elastic stretching mechanisms 5 is set to 2-4. The bottom plate of the flip aisle bracket 1 and the limit plate 303 are both provided with mounting grooves that cooperate with the elastic stretching mechanism 5. The elastic stretching mechanism 5 is installed in the mounting groove without exposing the mounting groove to avoid interference with the movement of the telescopic aisle bracket 2. The elastic stretching mechanism 5 includes a pair of U-shaped connecting members 501. The two connecting members 501 are fixedly connected to the bottom plate of the flip aisle bracket 1 and the limit plate 303, respectively. The two connecting members 501 are connected It is connected to a connecting rod 502, and a rectangular hole 503 is provided on the connecting piece 501 to cooperate with the connecting rod 502. The width of the rectangular hole 503 is greater than the diameter of the connecting rod 502, and the length is greater than the diameter of the connecting rod 502; a retaining ring 505 is fixedly connected to the end of the connecting rod 502, and the retaining ring 505 is threadedly connected to the connecting rod 502. A spring 504 is connected between the retaining ring 505 and the inner surface of the connecting piece 501, and the spring 504 is connected to the surface of the connecting rod 502. When the maintenance personnel walk on the telescopic aisle bracket 2, the fixed seat 301 and the telescopic aisle bracket 2 will shake slightly up and down. At this time, the spring 504 is compressed by force, which plays an elastic buffering role, protecting the connection between the fixed seat 301 and the flip aisle bracket 1, and avoiding the situation where the telescopic aisle bracket 2 is subjected to force and causes the connection to break.

[0036] like Figure 1 As shown, this embodiment also discloses a bridge inspection vehicle, which is a truss structure, including the above-mentioned flip bracket of the bridge inspection vehicle, wherein the flip bracket is connected to the lifting bracket, and the other components of the bridge inspection vehicle are all existing technologies and will not be repeated here.

[0037] When the flip bracket is in use, the driving motor 3043 drives the driving wheel 3042 to rotate, driving the telescopic aisle bracket 2 to extend. When the telescopic aisle bracket 2 is fully extended, the end of the telescopic aisle bracket 2 is connected to the rotating platform 302, and the insertion rod 202 is connected to the socket 3045. The rotating motor 401 drives the rotating platform 302 and the telescopic aisle bracket 2 to rotate to the specified position at the same time, and detects other positions of the bridge, thereby realizing the function of telescopic and rotating the telescopic aisle bracket 2, and solving the problem that the existing telescopic aisle bracket 2 can only be telescoped in a linear manner, resulting in a limited detection range.
