[0026] The technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical scheme and the technical effects brought about.

[0027] like Figure 1 As shown, a bridge deck concrete construction device includes rails 201 and a frame 1 respectively installed on both sides of the bridge deck, the frame 1 is installed with a travel assembly, the travel assembly includes a walking wheel 202 installed on the frame 1 and a driving motor for driving the walking wheel 202, and the walking wheel 202 is located in the rail 201; it also includes a material distribution assembly 3, a vibrating assembly 4 and a leveling assembly 5 installed on the frame 1; the material distribution assembly 3 includes a hopper 301 and a feeding pipe 303 connected to the bottom of the hopper 301; the vibrating assembly 4 includes a vibrating motor 402 , the output end of the vibration motor is connected to a vibrating rod 403; the leveling component 5 includes a vertically mounted linear drive structure, the output end of the linear drive structure is mounted with a placement plate 503, the placement plate 503 is mounted with multiple leveling motors 505, the output end of the leveling motor 505 is mounted with a leveling disk 506, and the linear drive structure can make the leveling disk 506 approach and move away from the bridge deck; the feeding pipe 303 is located at the front end of the frame 1, the vibrating rod 403 is located at the rear end of the feeding pipe 303, and the leveling disk 506 is located at the rear end of the vibrating rod 403.

[0028] The drive of the present invention is a drive motor and a running wheel 202. Tracks 201 are set on both sides of the bridge deck. The drive motor drives the running wheel 202 to move in the track 201. The movement of the running wheel 202 drives the frame 1 to move, and completes the movement of the present invention as a whole. The present invention also has a material distribution component 3, a vibration component 4 and a leveling component 5. During the movement of the present invention, the material distribution, vibration and leveling steps can be performed simultaneously. According to the positional relationship that the feed pipe 303 is located at the front end of the frame 1, the vibration rod 403 is located at the rear end of the feed pipe 303, and the smoothing plate 506 is located at the rear end of the vibration rod 403, the construction sequence of material distribution, vibration and leveling is ensured. Concrete material is placed in the hopper 301, and the concrete material is continuously poured onto the construction surface in front of the frame 1 using the feed pipe 303. The vibration motor drives the vibration rod 403 to complete the vibration of the concrete on the construction surface, and then the smoothing motor 505 drives the smoothing plate 506 to smooth the vibrated concrete on the construction surface.

[0029] like Figure 6As shown, further, it also includes a leveling component 6, which includes multiple hydraulic cylinders 601 installed on the frame 1, and the hydraulic cylinders 601 are arranged downward; it also includes a leveling plate, and the output ends of the multiple hydraulic cylinders 601 are all connected to the leveling plate, and the leveling plate is located at the rear end of the leveling plate 506. The leveling component 6 is used for the leveling step after the concrete is leveled. The hydraulic cylinder 601 drives the leveling plate to rise and fall, and adjusts it according to the construction standard of the bridge deck concrete pouring height, so that the height of the leveling plate from the bridge deck is the same as the concrete pouring height.

[0030] like Figure 2 As shown, further, it also includes a brush 9, which is located in the track 201 and at the front end of the walking wheel 202. The brush 9 fits the bottom of the track 201, and the brush 9 is connected to the frame 1 through a connecting rod. The brush 9 is connected to the frame 1 through a connecting rod, and is located at the front end of the walking wheel 202 and moves with the frame 1. During the movement, the brush 9 can process the garbage and gravel in the track 201 to avoid the garbage and gravel inside the U-shaped guide rail causing the walking wheel 202 to bump, affecting the normal operation of the leveling component 5 and the leveling component. Secondly, since the feeding pipe 303 and the tampering rod are located at the front end of the frame 1, part of the concrete will splash into the track 201 during the feeding and tampering process, and the concrete will affect the walking wheel 202, causing bumps. At this time, the concrete is not solidified, and the brush 9 can collect the concrete splashed into the track 201 on the brush 9 to avoid affecting the leveling component 5 and the leveling component.

[0031] like Figure 2 As shown, further, the track 201 is a U-shaped groove track 201, and the connecting rod is a T-shaped connecting rod 8, and the left and right ends of the T-shaped connecting rod 8 respectively abut on both sides of the inner wall of the U-shaped groove track 201. Conventional construction equipment completes the steps of spreading, vibrating, leveling and leveling in steps. Although the efficiency is low, they will not affect each other. Combining spreading, vibrating, leveling and leveling will cause the vibration generated during the spreading and vibrating process to be fed back to the frame 1, thereby affecting the working effect of the leveling and leveling assembly 6. The present invention is provided with a T-shaped connecting rod 8, so that the left and right ends of the T-shaped connecting rod 8 respectively abut on both sides of the inner wall of the U-shaped groove track 201, and the track 201 is fixed, so that the vibration of the frame 1 can be limited, and the vibration mainly fed back to the frame 1 from the vibrating step can be reduced, thereby ensuring the working effect of the leveling and leveling steps.

[0032] Furthermore, the travel wheel 202 is a universal wheel, which is installed at the bottom of both ends of the frame 1. The travel wheel 202 is a universal wheel, which can improve the flexibility and control of the present invention when running outside the track 201, such as in the material preparation process, and will not affect the travel effect when running inside the track 201 due to the limitation of the track 201.

[0033] like Figure 3 As shown, further, the hopper 301 is located at the top of the frame 1, and a discharge solenoid valve 304 and a support plate 302 are installed at the bottom of the hopper 301, and the support plate 302 is fixedly connected to the frame 1; there are multiple discharge pipes 303, and the multiple discharge pipes 303 are all connected to the discharge solenoid valve 304; the outlet ends of the multiple discharge pipes 303 are evenly arranged in the same row at equal intervals. The discharge solenoid valve 304 is opened to allow concrete to flow out along the discharge pipe 303 and be poured on the bridge deck, and the discharge solenoid valve 304 is closed to stop the discharge.

[0034] like Figure 7 As shown, further, a stirring motor 11 is also provided in the hopper 301, a stirring rod 12 is installed at the output end of the stirring motor 11, and a plurality of stirring blades 13 are layered on the stirring rod 12; a connecting plate 10 is also included, and both ends of the connecting plate 10 are respectively connected to the two ends of the hopper 301, and the stirring motor 11 is installed on the connecting plate 10; the hopper 301 is a funnel-shaped hopper 301.

[0035] like Figure 4 As shown, further, the vibrating assembly 4 also includes a mounting frame 401, which is fixedly installed inside the frame 1; there are multiple vibrating motors 402, each of which is equipped with a mounting frame 401, which are evenly spaced and arranged in a row and installed on the frame 1, so as to vibrate the concrete poured on the bridge deck to ensure the compactness of the concrete.

[0036] like Figure 5 As shown, further, the leveling assembly 5 also includes a mounting plate 501, which is fixedly mounted on the front end of the frame 1. The linear drive structure is an electric cylinder 502, which is two electric cylinders 502, which are respectively mounted at both ends of the mounting plate 501. There are multiple smoothing motors 505, which are evenly spaced and arranged in a row and mounted on the placement plate 503; the protective plate 504 is provided with two parallel protective plates 504, and multiple smoothing motors 505 are installed between the two protective plates 504. The electric cylinder 502 can be used to drive the fixed plate to rise and fall, and then the smoothing disc 506 can be driven to approach the concrete, and then the smoothing motor 505 can be used to drive the smoothing disc 506 to rotate, so as to roughen and level the concrete on the construction surface.

[0037] Furthermore, it also includes a control panel 7, which is electrically connected to the driving motor, the material distribution component 3, the vibration component 4, the leveling component 5 and the leveling component 6.

[0038] A control panel 7 is provided to control the present invention as a whole. The control panel 7 controls the driving motor to drive the frame 1 to move at a uniform speed, opens the discharge solenoid valve 304, and pours concrete in the construction surface through multiple discharge pipes 303, in front of the frame 1. At the same time, the vibrating motor 402 is started by the control panel 7, and then the vibrating motor 402 drives the vibrating rod 403 to vibrate. Then the electric cylinder 502 and the hydraulic cylinder 601 are started by the control panel 7. The electric cylinder 502 drives the fixed plate to rise and fall, and the hydraulic cylinder 601 drives the leveling plate to rise and fall. According to the construction standard of the bridge deck concrete pouring height, the height of the leveling plate from the bridge deck is adjusted to be the same as the height of the concrete pouring. At the same time, the lifting position of the fixed plate is to make the height of the smoothing plate 506 from the bridge deck the same as the height of the concrete pouring. While adjusting the leveling plate and the fixed plate, the smoothing motor 505 is turned on, and the smoothing plate 506 is rotated through the output shaft of the smoothing motor 505. The steps of spreading, vibrating, leveling and adjusting are carried out simultaneously to improve efficiency. The invention also does not require excessive human intervention during the working process, thus ensuring the safety of the bridge deck construction process.

[0039] It should be noted that the control panel 7 is equipped with a programmable PLC controller, which is used to conveniently control the material distribution component 3, the vibrating component 4, the leveling component 5, the leveling component 6 and the stirring component to realize the automated operation of the bridge deck material distribution, vibrating, leveling and roughening integrated device. The programmable PLC controller is any programmable PLC controller in the prior art adapted to the present invention. The structure of the programmable PLC controller is not an improvement of the present invention, and it only needs to be able to complete the control of the present invention.
