Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 shown, the first embodiment of the present invention provides a new type of cast-in-place box girder spraying maintenance vehicle, including a vehicle body 1 and a first upper pipe rack 2 and a second upper pipe rack 3 arranged on both sides of the vehicle body 1. A folding arm pipe rack 4, a flange pipe rack 5, a side pipe rack 6 and a lower pipe rack 7 are sequentially connected on one side of the vehicle body 1, and one end of the folding arm pipe rack 4 far from the flange pipe rack 5 is connected to the second upper pipe rack 3.

[0024] When performing the spraying maintenance operation of the box girder, the spraying pipes on the first upper pipe rack 2 and the second upper pipe rack 3 directly spray and maintain the top surface of the beam. The folding arm pipe rack 4 suspends the flange pipe rack 5, the side pipe rack 6 and the lower pipe rack 7 as a whole at the side position of the beam, and the spraying pipes on the flange pipe rack 5, the side pipe rack 6 and the lower pipe rack 7 respectively spray and maintain the flange plate, web and floor positions of the box girder, and utilize the movement of the vehicle body 1 to realize the spraying maintenance operation of the whole box girder.

[0025] AsFigures 2 to 5 As shown in the figure, in the second embodiment, a beam surface walking wheel 8 capable of telescoping is provided at one end of the second upper pipe rack 3 close to the folding arm pipe rack 4, and a beam edge walking wheel 9 is provided on the folding arm pipe rack 4.

[0026] During the walking of the vehicle body 1, the beam surface walking wheel 8 walks on the beam surface, having a supporting effect on the suspended end of the second upper pipe rack 3, improving the stability and suspension effect of the second upper pipe rack 3, the folding arm pipe rack 4, the flange pipe rack 5, the side pipe rack 6 and the lower pipe rack 7. At the same time, the beam edge walking wheel 9 walks on the side surface of the beam edge, supporting and limiting the folding arm pipe rack 4, the flange pipe rack 5, the side pipe rack 6 and the lower pipe rack 7 in the width direction, improving the overall stability of the folding arm pipe rack 4, the flange pipe rack 5, the side pipe rack 6 and the lower pipe rack 7, and further ensuring the safe, stable and efficient progress of the box girder spray curing operation.

[0027] In addition, the cooperation of the beam surface walking wheel 8 and the beam edge walking wheel 9 can more stably maintain the distance between each spray pipe and the box girder, ensuring that the spray operation is in the best state and improving the spray curing effect.

[0028] The beam surface walking wheel 8 is connected with a first wheel frame 10, and the first wheel frame 10 is installed at one end of the bottom of the second upper pipe rack 3 close to the folding arm pipe rack 4. The beam edge walking wheel 9 is connected with a second wheel frame 11, and the second wheel frame 11 is connected to the folding arm pipe rack 4.

[0029] Wherein, the second wheel frame 11 includes a fixed part 11.1 fixedly connected to the folding arm pipe rack 4 and a sliding part 11.2 slidably installed on the fixed part 11.1 in the inner and outer directions. A spring 12 is arranged between the fixed part 11.1 and the sliding part 11.2, and the beam edge walking wheel 9 is installed on the sliding part 11.2. By setting the spring 12, the elastic force of the spring 12 is used to support the beam edge walking wheel 9 to walk on the beam edge, which not only has a supporting effect but also has a buffering effect.

[0030] The first wheel frame 10 includes a column 10.1, a longitudinal elastic telescopic rod 10.2, a hinge plate 10.3, an upper rotating rod 10.4 and a lower rotating rod 10.5. The top end of the column 10.1 is fixed to one end of the ground of the second upper pipe rack close to the folding arm pipe rack 4. The top end of the longitudinal elastic telescopic rod 10.2 is fixedly connected to the inner side surface of the column 10.1. The hinge plate 10.3 is fixedly arranged at the bottom end of the longitudinal elastic telescopic rod 10.2. The beam surface walking wheel 8 is installed on the hinge plate 10.3. The top end of the upper rotating rod 10.4 is rotatably installed at the bottom end of the column 10.1. The bottom end of the lower rotating rod 10.5 is rotatably connected to the outer end of the hinge plate 10.3. The relative ends of the upper rotating rod 10.4 and the lower rotating rod 10.5 are rotatably connected. The upper rotating rod 10.4 and the lower rotating rod 10.5 form an isosceles triangle structure with the vertex facing outwards. A top plate 13 for inwardly pressing the connecting end of the upper rotating rod 10.4 and the lower rotating rod 10.5 is arranged on the fixed part 11.1.

[0031] Specifically, by the top plate 13 squeezing the connection ends of the first rotating rod and the second rotating rod inwardly, the hinged plate 10.3 will displace downward under the guiding action of the longitudinal elastic telescopic rod 10.2, so that the beam surface traveling wheels 8 are supported on the beam surface. When the top plate 13 is separated from the first connecting rod and the second connecting rod, during the retraction process of the longitudinal elastic telescopic rod 10.2, the first connecting rod and the second connecting rod will be folded, and the beam surface traveling wheels 8 will rise to leave the beam surface, realizing the storage of the beam surface traveling wheels 8.

[0032] The folding arm pipe rack 4 includes an upper rack body 4.1 and a lower rack body 4.2 which are distributed up and down. The top end of the lower rack body 4.2 is rotatably installed at the bottom end of the upper rack body 4.1, and the height of the rotation connection part between the upper rack body 4.1 and the lower rack body 4.2 is greater than the beam surface height. The fixed part 11.1 is fixedly connected to the upper rack body 4.1, the flange pipe rack 5 is connected to the bottom end of the lower rack body 4.2, and the sliding part 11.2 is connected to the lower rack body 4.2 through the limit pipe rack 14.

[0033] The limit pipe rack 14 can be kept in a vertical state by being supported by the beam edge traveling wheels 9, thereby maintaining the stability of the flange pipe rack 5, the side pipe rack 6 and the lower pipe rack 7.

[0034] A strip-shaped chute 15 is formed on the side surface of the lower rack body 4.2. One end of the limit pipe rack 14 is fixed to the sliding part 11.2, and a through groove 16 distributed inside and outside is formed at the other end of the limit pipe rack 14. Guide rods 17 are arranged on the outer sides of the inner wall surfaces on both sides of the through groove 16, and the two guide rods 17 are respectively located in the two strip-shaped chutes 15.

[0035] Specifically, when the folding arm pipe rack 4 is in an overall vertical state, the guide rod 17 is located at the top end of the strip-shaped chute 15. When the vehicle body 1 has a lateral offset during the traveling process and the folding arm pipe rack 4 approaches the side of the box girder, since the beam edge traveling wheels 9 are supported on the edge of the box girder, the position of the guide rod 17 remains unchanged. When the strip-shaped groove displaces inward outside the guide rod 17, the bottom end of the lower rack body 4.2 will turn outward, and then the flange pipe rack 5, the side pipe rack 6 and the lower pipe rack 7 will be all swung out of the range below the side of the beam body, preventing the flange pipe rack 5, the side pipe rack 6 and the lower pipe rack 7 from hitting the box girder, so as to achieve good protection performance.

[0036] Among them, a turntable 18 that rotates in the horizontal direction is installed at one end of the second pipe support close to the folding arm pipe support 4. The top end of the folding arm pipe support 4 is rotationally connected to the turntable 18 in the height direction. The folding arm pipe support 4, the flange pipe support 5, the side pipe support 6, and the lower pipe support 7 are sequentially rotationally connected in the height direction. Electric telescopic rods 19 are provided between the turntable 18 and the folding arm pipe support 4, between the folding arm pipe support 4 and the flange pipe support 5, between the flange pipe support 5 and the side pipe support 6, and between the side pipe support 6 and the lower pipe support 7. The lower pipe support 7, the side pipe support 6, and the flange pipe support 5 can be sequentially folded by the electric telescopic rods. The folded whole can be rotated to the inward state by using the turntable 18, and then the whole can be stored on the side of the vehicle body 1 by the rotation of the second upper pipe body.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
