[0015] The following is a detailed description of the specific implementation of the present invention.

[0016] like Figures 1 to 7As shown, it is a structural diagram of a road and bridge maintenance spray device provided by the present invention, comprising a T-frame 1, a horizontal adjustment mechanism 100, an elastic pressing mechanism 200, a directional drive mechanism 300, a synchronous drive mechanism 400 and a spray system 500, wherein the horizontal adjustment mechanism 100 is arranged in pairs and symmetrically installed at the horizontal ends of the T-frame 1, and the inner side of the bottom end of the horizontal adjustment mechanism 100 contacts the road and bridge crash barrier; the elastic pressing mechanism 200 is arranged at the bottom end of the T-frame 1, and the elastic pressing mechanism 200 contacts the top of the road and bridge crash barrier during the movement of the horizontal adjustment mechanism 100; the directional drive mechanism 300 is arranged There are two of them, which are respectively installed on the fixed ring sleeve 3 in the horizontal adjustment mechanism 100, and adjust the spray angle when working; the synchronous drive mechanism 400 is installed on the T-frame 1 and driven by an independently arranged motor. The synchronous drive mechanism 400 is also connected to the directional drive mechanism 300 in transmission, so as to drive the directional drive mechanism 300 to deflect when the motor is working, and the elastic adjustment unit arranged on the T-frame 1 adjusts the tightness; the spray system 500 is arranged on the T-frame 1, the elastic tightening mechanism 200 and the directional drive mechanism 300, so as to evenly spray its surface when moving along the crash barrier of the road bridge.

[0017] In one example of the present invention, the external motor and the pump body built into the liquid storage tank 23 are electrically connected to an independently arranged controller to facilitate control of the spraying process. At the same time, the traveling equipment includes a rotating motor and a control system, which can drive the device to move smoothly along the surface of the road and bridge crash barrier when working.

[0018] like Figure 1 As shown, as a preferred embodiment of the present invention, the horizontal adjustment mechanism 100 includes a horizontal telescopic member 2, a fixed ring sleeve 3, a movable frame 5 and a roller 6; The horizontal telescopic member 2 is installed at the end of the T-shaped frame 1, and the end of the horizontal telescopic member 2 is fixedly connected to a fixed ring sleeve 3, and a movable frame 5 is longitudinally installed at the bottom of the fixed ring sleeve 3; A group of rollers 6 are rotatably mounted on the inner side of the movable frame 5.

[0019] In one example of the present invention, when the spacing between adjacent rollers 6 needs to be changed to adapt to different widths of road and bridge crash barriers, the fixed ring sleeves 3, movable frames 5 and rollers 6 on both sides are pushed to move in opposite directions through the arranged horizontal telescopic members 2, so that adjacent rollers 6 are moved closer or farther away, and the rollers 6 are driven by a separate external traveling device to facilitate the movement of the driving device along the surface of the road and bridge crash barrier.

[0020] like Figure 1 and Figure 2 As shown, as another preferred embodiment of the present invention, the elastic pressing mechanism 200 includes a movable frame 2 7, a roller 2 8 and a fixing rod 9; The movable frame 2 7 is slidably mounted on the bottom end of the T-shaped frame 1, and a roller 2 8 is rotatably arranged at the bottom of the movable frame 2 7, and the roller 2 8 contacts the road bridge anti-collision wall; The movable frame 2 7 is also connected to the elastic support member 1 installed in the T-shaped frame 1 , and a fixing rod 9 is installed on the side of the movable frame 2 7 .

[0021] In one example of the present invention, by arranging an elastic support member 1, the bottom end of the roller 2 8 can be in contact with the top of the road bridge crash barrier, and when the device moves along the road bridge crash barrier, the roller 2 8 rotates along the movable frame 2 7, and the fixed rod 9 moves synchronously with the movable frame 2 7 in the height direction.

[0022] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the directional drive mechanism 300 includes a guide rod 4, a support 10, a driven gear 11, a tooth portion 12 and a spray pipe 13; The guide rod 4 is slidably mounted on the fixed ring sleeve 3, and a tooth portion 12 is partially provided on the side surface of the guide rod 4; The support 10 is fixedly mounted on the outside of the fixed ring sleeve 3, and a driven gear 11 is rotatably mounted on the support 10, and the driven gear 11 is meshed with the tooth portion 12; The spray pipe 13 is fixedly connected to the bottom of the guide rod 4 and swings synchronously with the guide rod 4 .

[0023] In one example of the present invention, when the driven gear 11 is rotated along the support 10 under force, since the driven gear 11 is in a meshing state with the tooth portion 12, the guide rod 4 can be driven to slide along the fixed ring sleeve 3 through the set tooth portion 12 when the driven gear 11 rotates, and the spray pipe 13 at the bottom slides synchronously with the guide rod 4; in addition, the shape and size of the spray pipe 13 can be adjusted as needed so that it is equidistant from both sides of the road and bridge crash barrier after the swinging state.

[0024] At the same time, in order to improve the accuracy of spraying, the spray pipe 13 can also be set to a split structure, including a fixed end and a movable end, the movable end is hinged on the fixed end, and fine-tuned by a built-in micro telescopic rod, as shown in the accompanying drawings of the specification. Figure 7 shown.

[0025] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the synchronous drive mechanism 400 includes a rotating shaft 14, a driving gear 15, a pulley 16, a synchronous belt 17 and a pulley 2 18; The rotating shafts 14 are provided with two, which are rotatably mounted on the T-shaped frame 1 respectively, and a driving gear 15 is mounted on each rotating shaft 14, and adjacent driving gears 15 are meshed; A pulley 16 is also installed at the end of the rotating shaft 14 , and a pulley 2 18 is installed at the end of the driven gear 11 . The pulley 16 and the pulley 2 18 are connected by a synchronous belt 17 .

[0026] In one embodiment of the present invention, when the rotating shaft 14 on one side is subjected to force to rotate along the T-frame 1, the driving gear 15 at the corresponding position rotates synchronously therewith. Since the driving gears 15 on both sides are in a meshing state, they can simultaneously drive the rotating shaft 14 on the other side to rotate synchronously, thereby driving the pulley 1 16 on the two rotating shafts 14 to rotate, and driving the pulley 2 18 and the driven gear 11 to rotate along the support 10 through the set synchronous belt 17.

[0027] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the elastic adjustment unit includes a roller 3 19, a movable block 20, a guide groove 21 and an elastic support member 22; The movable block 20 is installed on the T-shaped frame 1, and the movable block 20 is slidably connected to a guide groove 21 provided on the T-shaped frame 1, and an elastic support member 22 connected to the movable block 20 is arranged in the guide groove 21; The movable block 20 is rotatably provided with a roller 3 19 , which abuts against the inner side of the synchronous belt 17 .

[0028] In one example of the present invention, when the horizontal telescopic member 2 works to push the fixed ring sleeve 3 to move in the horizontal direction, the synchronous belt 17 is deformed by force, the roller three 19 is forced to push the movable block 20 to slide along the guide groove 21, and the elastic support member two 22 is elastically deformed by force. At the same time, the movable block 20 in the present application can be placed in the middle position of the guide groove 21.

[0029] like Figure 1 and Figure 6 As shown, as another preferred embodiment of the present invention, the spray system 500 includes a liquid storage tank 23, a liquid delivery tube 24, a flow channel 1 25, a flow channel 26, a spray hole 27, a cross bar 28, a liquid distribution tube 29 and a spray head 30; The liquid storage tank 23 is fixedly mounted on the side of the T-shaped frame 1, and the liquid storage tank 23 is communicated with the flow channel 1 25 opened in the fixed ring sleeve 3 through the arranged infusion pipe 24, and the flow channel 1 25 is communicated with the flow channel 2 26 opened in the spray pipe 13, and a plurality of spray holes 27 connected with the flow channel 2 26 are arranged on the side of the spray pipe 13; The cross bar 28 is fixedly mounted on the end of the fixed rod 9 . The interior of the cross bar 28 is a hollow structure and is connected to the flow channel 1 25 through a liquid distribution pipe 29 . A plurality of nozzles 30 are also mounted on the bottom of the cross bar 28 .

[0030] In one example of the present invention, when the device moves along the surface of the road and bridge crash barrier, the built-in pump body in the liquid storage tank 23 works to draw out the liquid in the liquid storage tank 23 and transport it along the infusion pipe 24 and the flow channel 1 25. A part of it is sprayed from the spray hole 27 to the two sides of the road and bridge crash barrier, and the other part passes through the liquid distribution pipe 29 along the flow channel 1 25 into the cross bar 28, and finally sprayed from the bottom nozzle 30 to the top of the road and bridge crash barrier. At the same time, since the roller 2 8 is in contact with the road and bridge crash barrier, the purpose of controlling the spraying distance of the nozzle 30 can be achieved.

[0031] In summary, the device is placed on the road and bridge crash barrier as needed, and driven by the traveling equipment, the entire device moves along the surface of the road and bridge crash barrier, and the motor drives the rotating shaft 14 to rotate. Due to the meshing of the driving gears 15 on both sides, the rotating shaft 14 on the other side and the pulley 16 can be driven to rotate synchronously, and the synchronous belt 17 drives the pulley 2 18 and the driven gear 11 to rotate along the support 10. The driven gear 11 is meshed with the tooth portion 12, and can push the guide rod 4 to slide along the fixed ring sleeve 3, and the spray pipe 13 swings synchronously therewith to adjust the spray angle of the spray pipe 13. At the same time, the built-in pump body in the liquid storage tank 23 works to extract the liquid in the liquid storage tank 23 and transport it along the infusion pipe 24 and the flow channel 1 25, and a part of it is sprayed from the spray hole 27. Towards both sides of the road and bridge crash barrier, the other part goes along the flow channel 25 through the liquid distribution pipe 29 into the cross bar 28, and is finally sprayed from the bottom nozzle 30 to the top of the road and bridge crash barrier. During the spraying process, when the width of the road and bridge crash barrier changes, the horizontal telescopic member 2 pushes the fixed ring sleeve 3, the movable frame 5 and the roller 6 to move in opposite directions to maintain the contact state with the road and bridge crash barrier. The roller three 19 is forced to push the movable block 20 to slide along the guide groove 21, and the elastic support member two 22 is elastically deformed under force. The spraying device can adapt to road and bridge crash barriers of different sizes, and can effectively control the trajectory of liquid spraying during the movement along the road and bridge crash barrier, thereby realizing uniform spraying of the road and bridge crash barrier, so as to fully maintain the road and bridge crash barrier and improve the maintenance quality of the road and bridge crash barrier.

[0032] It will be apparent to those skilled in the art that the invention is not limited to the exemplary details set forth above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, in every respect, the present invention is to be regarded as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than by the foregoing description, and it is intended that all variations within the meaning and scope of the equivalent elements of the claims be included in the present invention.
