[0017] Please refer to Figures 1-4The utility model provides following technical scheme: including support board 1, support frame 11 and connecting frame 12, support frame 11 inner wall has the hinged plate 3 of hinging, support board 1 inner wall fixedly connected with the arc -shaped frame 33 corresponding with one end of hinged plate 3, one end fixedly connected with the limit post 32 of hinged plate 3, the arc -shaped frame 33 is set up with the arc -shaped slot 331 of matching of limit post 32, support frame 11 is set up with corresponding upper let -by hole 34 and lower let -by hole 341, and the sliding plate 35 is slidably connected on support board 1, and the motor 36 is installed on sliding plate 35, and the motor 36 drive end fixedly connected with the adjusting rod 37, and the rotating block 38 of screw connection with adjusting rod 37 is rotatably connected with the both sides of hinged plate 3.

[0018] In the embodiment: the support plate 1 is the carrier of the bearing device, so that the support plate 1 can bear the construction personnel, and the support frame 11 installed on the support plate 1 protects the upper side of the support plate 1 and protects the work of the construction personnel. The connecting frame 12 is installed on one side of the support frame 11, and at this time the connecting frame 12 is used to be fixed on the bridge side construction vehicle, so that it can erect and fix the connecting frame 12 and the support plate 1, so that the support plate 1 can be stably placed on one side of the bridge deck to facilitate the construction personnel to work on the side of the bridge. However, when in use, the construction vehicle on the bridge deck is horizontally supported on the bridge deck, and the connecting frame 12 and the support plate 1 horizontally correspond to the construction vehicle, so that they have a certain angle, which reduces the safety of the support plate 1 during use, thereby affecting the safe work of the construction personnel. At this time, one end of the hinged plate 3 installed on the support plate 1 can be hinged in the inner wall of the support frame 11, and the hinged plate 3 is located at the bottom of the support frame 11. At this time, the other end of the hinged plate 3 is limited between the arc-shaped frames 33 installed on the support frame 11. The limiting column 32 fixedly connected to one end of the hinged plate 3 is limited in the arc-shaped clamping groove 331 formed in the arc-shaped frame 33. The hinged plate 3 can be angle-adjusted by being hinged between the support frame 11 and the arc-shaped frame 33. The hinged plate 3 can be kept horizontally corresponding to the horizontal plane after the angle adjustment of the hinged plate 3. When the angle of the hinged plate 3 is adjusted, the rotating blocks 38 rotatably connected to both sides of the hinged plate 3 are screwed with the adjusting rods 37. The adjusting rods 37 are fixedly connected with the driving end of the motor 36 slidably connected with the support frame 11. The motor 36 can slide on the support frame 11 through the sliding plate 35. The adjusting rods 37 are allowed by the upper and lower limiting holes 34 and 341. When the angle of the hinged plate 3 is adjusted, the rotating blocks 38 rotate on both sides of the hinged plate 3. After the angle adjustment of the hinged plate 3, the rotating blocks 38 can still correspond to the adjusting rods 37 vertically, and the position of the rotating blocks 38 on the support plate 1 changes, so that the position of the sliding plate 35 can be adjusted, thereby ensuring that the support plate 1 is on the side of the bridge when the construction personnel uses the bridge side construction vehicle, and the construction personnel can work on the hinged plate 3 horizontally corresponding to the horizontal plane, thereby ensuring the safety of the construction work.

[0019] The first driving telescopic rod 2 fixedly connected to the inner wall of the support frame 11 can adjust the height of the upper protection frame 21 above the support plate 1, and when the upper protection frame 21 is above the support frame 11, the limit rod 22 fixedly connected to the bottom end of the upper protection frame 21 is in sliding connection with the support frame 11, so that the first driving telescopic rod 2 can adjust the erection height of the upper protection frame 21 when the construction personnel work, thereby ensuring the protection of the device on the construction personnel.

[0020] The upper and lower let holes 34 and 341 correspond to the adjusting rod 37, and one end of the hinged plate 3 is hinged to the inner wall of the support plate 1 through the hinge block 31; the adjusting rod 37 and the upper and lower let holes 34 and 341 correspond to each other, so that the motor 36 and the adjusting rod 37 need to correspond to the position of the rotating block 38, and the motor 36 and the adjusting rod 37 can slide horizontally on the support frame 11, thereby ensuring the adjustment of the angle of the hinged plate 3.

[0021] The support plate 1 is provided with a limiting groove 382, and the limiting groove 382 is in sliding connection with a limiting block 381; the limiting block 381 is in rotating connection with the bottom of the adjusting rod 37; the limiting groove 382 provided on the support plate 1 is used for installing the limiting block 381, so that the limiting block 381 can slide on the inner wall of the limiting groove 382, the adjusting rod 37 is stably installed on the support frame 11, and the position of the adjusting rod 37 can be adjusted mechanically, so that the adjusting rod 37 can correspond to the rotating block 38.

[0022] The support frame 11 is fixedly connected with two butt plates 352 on both sides, one side of one butt plate 352 is provided with a second driving telescopic rod 353, one end of the second driving telescopic rod 353 penetrates through the butt plate 352, one side of the sliding plate 35 is fixedly connected with a push plate 351, and one end of the second driving telescopic rod 353 is fixedly connected with one side of the push plate 351; the butt plates 352 fixedly connected to the support frame 11 correspond to the push plate 351, so that the second driving telescopic rod 353 installed on one side of the butt plate 352 can control the position of the sliding plate 35, thereby controlling the positions of the motor 36 and the adjusting rod 37, so that when the angle of the rotating block 38 is adjusted, the sliding plate 35 is pushed to slide, and the angle of the hinged plate 3 is adjusted.

[0023] The sliding rod 354 is fixedly connected between the butt plates 352 and is staggered with the second driving telescopic rod 353, and the sliding rod 354 is in sliding connection with the push plate 351; the sliding rod 354 is staggered with the second driving telescopic rod 353, so that the sliding rod 354 limits the position of the push plate 351, thereby ensuring that the sliding rod 354 is horizontally displaced on both sides of the top of the support frame 11 and ensuring that the sliding plate 35 is horizontally adjusted.

[0024] The working principle and use process of the utility model: when the support plate 1, support frame 11 and connecting frame 12 are supported by the construction vehicle and are on the side of the bridge deck, at this time, the support plate 1 is inclined due to the influence of the slope of the bridge deck, at this time, the sliding plate 35 can slide on the support frame 11, the motor 36 drives the adjusting rod 37, the adjusting rod 37 can adjust the position of the rotating block 38, and through the sliding of the sliding plate 35, the adjusting rod 37 can correspond to the rotating block 38 at any time, avoiding limiting, the hinged plate 3 can be angle adjusted, cooperating with the limiting of the arc-shaped frame 33, after the angle adjustment of the hinged plate 3, the hinged plate 3 can keep corresponding to the horizontal plane, so that the device can ensure that the support plate 1 is on the side of the bridge deck when the construction personnel uses the construction vehicle on the side of the bridge, the construction personnel can work on the hinged plate 3 which is flush with the horizontal plane, ensuring the safety of the construction work.
