Description

Technical Field

[0001] The utility model relates to the technical field of bridge deck system construction devices, in particular to a bridge deck system construction device with a smoothing function. Background Art

[0002] Bridge deck concrete construction equipment is a series of equipment and tools specially used for bridge deck concrete construction, including concrete mixing plants, transport vehicles, pumping equipment, pouring equipment, formwork support systems and maintenance equipment, etc. They work together to ensure the smooth progress of the entire process from concrete production to pouring, leveling and maintenance to meet the quality, efficiency and safety requirements of bridge deck construction.

[0003] For example, the Chinese authorized patent "A bridge deck concrete construction device" with announcement number CN218757027U includes a box body, a material bin is arranged outside the box body, a flattening roller is arranged on the lower side of the fixed plate, two extension rollers are symmetrically arranged on both sides of the flattening roller, and rotating rods are rotatably arranged inside the extension roller and the flattening roller. Through the above structure, three material bins are arranged in three directions of the box body, and valve plates are arranged on the material bins. A second electric push rod is arranged on one side of the valve plate. The second electric push rod can drive the valve plate to move up and down, making it easy to discharge materials. Discharging materials through the material bins in three directions of the device makes it easy to discharge a wider range of construction materials. The flattening roller is rotatably connected to the outer side of the rotating rod, and the other two sides of the connecting plate are symmetrically fixedly connected to the locking seat, and one end of the locking seat is threadedly connected to the rotating rod, and an extension roller is arranged on the outer side of the rotating rod.

[0004] Although the above-mentioned prior art can realize the laying of bridge deck concrete, there are bubbles in the concrete after laying. Although subsequent leveling work is performed, the bubbles will cause defects in the concrete plane after leveling, and the height position of the leveling mechanism follows the moving mechanism. If the moving mechanism moves to an uneven bridge deck, it will inevitably cause the leveling mechanism to have a vertical deviation on the concrete, thereby affecting the construction effect. Therefore, it does not meet the existing needs. In this regard, we propose a bridge deck construction device with a leveling function. Utility Model Content

[0005] The utility model aims to provide a bridge deck construction device with a smoothing function to solve the problem in the above-mentioned background technology that the concrete smoothing effect of the bridge deck construction device is affected by bubbles in the concrete and uneven road surface.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge deck construction device with a smoothing function, comprising a base, rollers are installed at the four corners of the bottom of the base, a mixing box is fixedly installed on the front side of the upper end surface of the base, a feed port is provided at the upper end of the mixing box, and a concrete discharge pipe connected to the mixing box is installed at the bottom of the base; and further comprising:

[0007] A vibration mechanism is arranged at the rear end of the bottom of the base, the vibration mechanism is horizontally slidably connected to the base, and the width of the slide groove connecting the base and the upper end of the vibration mechanism is larger than the vibration mechanism, springs are fixedly installed between the two sides of the upper end of the vibration mechanism and the slide groove of the base, and a plurality of equally spaced vibration rods are arranged at the bottom of the vibration mechanism;

[0008] A smoothing mechanism is arranged at the rear end of the vibration mechanism, an electric push rod is installed above the smoothing mechanism, the movable end of the electric push rod is fixed to the smoothing mechanism, and the fixed end of the electric push rod is fixed to the base, a scraper is installed at the bottom of the smoothing mechanism, and the scraper and the smoothing mechanism are fixed by screws.

[0009] Preferably, a power box is fixedly installed on the rear side of the upper end surface of the base, a driving power supply and a processor are provided inside the power box, a laser receiver is fixedly installed on the front end of the power box, the output end of the laser receiver is electrically connected to the input end of the processor, and the output end of the processor is electrically connected to the electric push rod, a positioning rod is provided at the position of the bridge deck corresponding to the laser receiver, a laser emitter is rotatably installed above the positioning rod, and the laser emitter is driven by the motor inside the positioning rod.

[0010] Preferably, a first motor is installed at the rear end of the mixing box, and a mixing rod extending into the interior of the mixing box is installed on the output shaft of the first motor, and a mixing blade is fixedly installed on the outside of the mixing rod.

[0011] Preferably, a rack plate is fixedly provided on the front side of the upper end of the vibration mechanism, a fan gear is installed at the front end of the rack plate, the fan gear is rotatably connected to the base, and the outer gear ring of the fan gear is meshed with the rack plate for transmission, and a second motor is installed on the shaft at the upper end of the fan gear.

[0012] Preferably, a push rod is welded and fixed to the front end of the mixing box.

[0013] Preferably, an electric-controlled valve is installed at the upper end of the concrete discharge pipe.

[0014] Preferably, the scraper has an inclined structure.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is provided with a vibration mechanism, which is installed at the rear of the concrete discharge pipe. After the concrete is paved on the bridge deck, the vibration rod then enters the concrete. By turning on the second motor, its output shaft drives the sector gear to rotate. When the sector gear ring contacts the rack plate at the rear end of the vibration mechanism, the meshing action drives the vibration mechanism to move a short distance to one side. As the sector gear continues to rotate, the two will lose meshing. Under the action of the spring, the vibration mechanism is reset again, and this reciprocating process forms a high-frequency vibration of the vibration rod below the vibration mechanism. The vibration force is continuously transmitted inside the concrete, thereby quickly discharging the remaining bubbles inside, ensuring that the concrete remains in a relatively compact state, providing a prerequisite for leveling work.

[0017] 2. The utility model adopts laser positioning to adjust the height of the scraper in real time. A positioning rod is set near the construction area. The laser transmitter on the upper end of the positioning rod can emit a rotating light beam to form an accurate reference plane on the bridge deck, which serves as a reference for the operation of the smoothing mechanism. The laser receiver installed at the front end of the power box can detect the laser signal and convert it into an electrical signal to adjust the action of the smoothing mechanism. A processor is arranged inside the power box. The processor receives the electrical signal from the laser receiver and calculates the height difference between the smoothing mechanism and the light plane based on these signals. If it is detected that the smoothing mechanism is higher than the light plane, the electric push rod will lower the height of the smoothing mechanism. Conversely, if the smoothing mechanism is lower than the light plane, the electric push rod will raise the height of the smoothing mechanism to ensure that the smoothing mechanism always maintains the same horizontal line with the light plane, so as to avoid the moving mechanism moving to an uneven bridge deck, causing the smoothing mechanism to have a vertical deviation of the concrete, thereby affecting the construction effect.

The movable end of the electric push rod 16 is fixed to the smoothing mechanism 5, and the fixed end of the electric push rod 16 is fixed to the base 1. A scraper 6 is installed at the bottom of the smoothing mechanism 5, and the scraper 6 is fixed to the smoothing mechanism 5 by screws.

[0027] When in use, a positioning rod 17 is set near the construction area. The laser transmitter 18 at the upper end of the positioning rod 17 can emit a rotating light beam to form an accurate reference plane on the bridge deck, which serves as a reference for the operation of the smoothing mechanism 5. The laser receiver 9 installed at the front end of the power box 8 can detect the laser signal and convert it into an electrical signal to adjust the action of the smoothing mechanism 5. A processor is provided inside the power box 8. The processor receives the electrical signal from the laser receiver and calculates the height difference between the smoothing mechanism 5 and the light plane based on these signals. If it is detected that the smoothing mechanism 5 is higher than the light plane, the electric push rod 16 will lower the height of the smoothing mechanism 5. Conversely, if the smoothing mechanism 5 is lower than the light plane, the electric push rod 16 will raise the height of the smoothing mechanism 5 to ensure that the smoothing mechanism 5 always maintains the same horizontal line with the light plane.

[0028] See also Figure 1 and Figure 2A power box 8 is fixedly installed on the rear side of the upper end surface of the base 1, and a driving power supply and a processor are arranged inside the power box 8. A laser receiver 9 is fixedly installed on the front end of the power box 8. The output end of the laser receiver 9 is electrically connected to the input end of the processor, and the output end of the processor is electrically connected to the electric push rod 16. A positioning rod 17 is provided at the position of the bridge deck corresponding to the laser receiver 9. A laser transmitter 18 is rotatably installed above the positioning rod 17, and the laser transmitter 18 is driven by the motor inside the positioning rod 17 to prevent the moving mechanism from moving to an uneven bridge deck, causing a vertical deviation of the concrete by the leveling mechanism 5, thereby affecting the construction effect.

[0029] See also Figure 2 A first motor 10 is installed at the rear end of the mixing box 2, and a stirring rod 13 extending into the interior of the mixing box 2 is installed on the output shaft of the first motor 10. A stirring blade 14 is fixedly installed on the outside of the stirring rod 13. This structure can improve the construction efficiency of the bridge deck, and cooperate with the smoothing mechanism 5 to further improve the overall paving quality.

[0030] See also Figure 2 and Figure 3 A rack plate 20 is fixedly provided on the front side of the upper end of the vibration mechanism 3, a fan-shaped gear 19 is installed at the front end of the rack plate 20, the fan-shaped gear 19 is rotatably connected to the base 1, and the outer gear ring of the fan-shaped gear 19 is meshed with the rack plate 20 for transmission, and a second motor 22 is installed on the shaft at the upper end of the fan-shaped gear 19. The vibration force generated is continuously transmitted inside the concrete, thereby quickly discharging the remaining bubbles inside, ensuring that the concrete remains in a relatively compact state, providing a prerequisite for leveling work.

[0031] See also Figure 1 and Figure 2 A push rod 12 is welded and fixed to the front end of the mixing box 2, and a staff member is located inside the push rod 12 to push the whole to move forward.

[0032] See also Figure 2 An electric control valve is installed at the upper end of the concrete discharge pipe 15.

[0033] See also Figure 1 and Figure 2 , the scraper 6 has an inclined structure.

[0034] Working principle: When in use, after concrete is poured into the interior from the feed port 11, the first motor 10 is turned on, and its output shaft drives the stirring rod 13 to rotate, and then drives the stirring blade 14 to rotate, so as to form agitation of the internal concrete, avoid the concrete from condensing inside the mixing box 2, and improve the mixing effect of the concrete. When paving the bridge deck, the valve on the concrete discharge pipe 15 is opened, so that the concrete inside the mixing box 2 can be evenly discharged from the concrete discharge pipe 15, so as to be paved on the bridge deck. At this time, the vibrating rod 4 then enters the concrete, and the second motor 22 is turned on, and its output shaft drives the sector gear 19 to rotate. When the sector gear 19 tooth ring contacts the rack plate 20 at the rear end of the vibration mechanism 3, the meshing action drives the vibration mechanism 3 to move a short distance to one side. As the sector gear 19 continues to rotate, the two will lose meshing. Under the action of the spring 21, the vibration mechanism 3 is reset again, and this reciprocating motion forms a high-frequency vibration of the vibration rod 4 below the vibration mechanism 3. The vibration force is continuously transmitted inside the concrete, so that the remaining bubbles inside are quickly discharged.
