Technical Field

[0001] This invention belongs to the field of road and bridge concrete paving technology, specifically referring to a road and bridge concrete paving material conveyor. Background Technology

[0002] A concrete paver is a construction machine used for laying concrete in road, bridge and other engineering projects. It consists of a frame, a paving roller, a vibration device and a control system, and has the functions of spreading, vibrating and compacting, and forming concrete.

[0003] In road and bridge construction, concrete needs to be unloaded and transported using cement trucks. However, the area of ​​concrete paving for roads and bridges is relatively large, and it is difficult to balance and control the amount of cement paving at different paving locations. This usually leads to uneven paving, which increases the workload for construction workers. In addition, some lumps are inevitable in the cement, which is detrimental to the overall quality of the cement and makes it difficult to spread cement in subsequent stages. Therefore, it is necessary to propose a concrete paving and conveying machine for roads and bridges. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a road and bridge concrete paving conveyor, which effectively solves the problems of uneven paving amount and lumps in concrete that are not conducive to paving during the existing road and bridge concrete paving conveying process.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a concrete paving and conveying machine for roads and bridges, including a paving and unloading control component capable of achieving uniform paving, a vibration mechanism capable of improving concrete quality, an unloading guide hopper, a bottom support frame, a bottom guide rail, and a guide wheel. The bottom guide rail is set on a plane, the guide wheel is fitted and slidably set on the bottom guide rail, the bottom support frame is fixed to the guide wheel, the vibration mechanism is set on the bottom support frame, the unloading guide hopper is set on the bottom support frame, and the paving and unloading control component is set on the unloading guide hopper. This invention can solve the problem of uneven paving amount during the paving and conveying process of concrete for roads and bridges.

[0006] Preferably, the paving unloading control assembly includes a paving unloading motor, a receiving sleeve, a fixed guide housing, a bottom connecting rod, a lightweight disc, a winding rotating shaft, an unloading swing arm, a sealing arc plate, an unloading frame, and an unloading operation trough. The unloading frame is mounted on the unloading guide hopper, and the unloading operation trough is arranged in two groups on the unloading frame. A vertical unloading cylinder is connected to the bottom of the unloading guide hopper, and the bottom of the vertical unloading cylinder is open. The winding rotating shaft is rotatably mounted on the vertical unloading cylinder and the unloading frame, and the unloading swing arm is rotatably mounted on both. The sealing arc plate is fixed to the bottom of the unloading swing arm and attached to the winding rotating shaft. The body of the paving and unloading motor is located on the outer wall of the unloading frame. The output end of the paving and unloading motor is connected to the winding rotating shaft. The receiving sleeve is spirally wound at the end of the winding rotating shaft. The fixed guide shell is fixed to the outer wall of the unloading frame. The receiving sleeve is vertically slidably installed in the fixed guide shell. The bottom connecting rod is located at the bottom of the receiving sleeve. The lightweight disc is located on the bottom connecting rod. The lightweight disc can contact the object with its bottom.

[0007] Furthermore, the bottom end face of the lightweight disc is equipped with a motor touch switch and a hardened touch switch, which can trigger the internal circuit after contacting an object; the interior of the receiving sleeve is filled with electrorheological fluid, and parallel plate capacitors are embedded on the inner wall of the receiving sleeve. The parallel plate capacitors are arranged in pairs between the inner walls of the receiving sleeve. The hardened touch switch and the parallel plate capacitors are electrically connected, and the motor touch switch and the paving and unloading motor are electrically connected.

[0008] The vibration mechanism includes a reciprocating drive motor, a rotating rocker arm, a protruding part, a rotating ring, and a vibrating rotating bracket. The body of the reciprocating drive motor is mounted on the bottom support frame, the vibrating rotating bracket is fixed to the bottom support frame, the rotating rocker arm is rotatably mounted between the vibrating rotating brackets, the output end of the reciprocating drive motor is connected to the rotating rocker arm, the protruding part is located in the middle section of the rotating rocker arm, and the rotating ring is rotatably sleeved on the protruding part.

[0009] Preferably, the bottom support frame is rotatably equipped with side swing arms, and there are four sets of side swing arms. Each of the four sets of side swing arms is equipped with a vibrating feeder, and the vibrating feeder is equipped with a sieve hole, which can intercept the lumps in the concrete and improve the quality of the treated concrete.

[0010] Preferably, one end of the vibrating feeder is provided with a feed port, and the bottom of the vibrating feeder is hinged with a bottom connecting frame, which is connected to the rotating ring.

[0011] The sealing arc plate can rotate to fit the bottom opening of the vertical unloading cylinder, and can seal the bottom of the vertical unloading cylinder in the initial state.

[0012] Furthermore, the receiving sleeve, lightweight disc, motor touch switch, and hardened touch switch are provided in two sets. The two sets of receiving sleeves can control the concrete discharge volume of the two sets of vertical discharge cylinders through the motor touch switch and the hardened touch switch respectively.

[0013] Furthermore, the vibrating feeder and the unloading guide hopper correspond to each other in the vertical direction.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a concrete paving and conveying machine for roads and bridges, which effectively solves the problems of uneven paving volume and lumps in concrete that are not conducive to paving during the existing concrete paving and conveying process for roads and bridges. This method brings the following advantages: (1) In order to overcome the problem of uneven paving volume during the concrete paving and conveying process of road and bridge, this invention proposes a paving and unloading control component. In the initial state, the sealing arc plate completely blocks the vertical unloading cylinder, which can block the bottom of the vertical unloading cylinder. The concrete is temporarily stored in the vertical unloading cylinder. After the paving and unloading motor is started, the lightweight disc moves downward. This invention can automatically control the unloading volume of concrete according to the original concrete paving volume at the construction location. When the winding rotating shaft drives the unloading swing arm to rotate a small arc length, the opening formed by the sealing arc plate at the bottom of the vertical unloading cylinder is smaller, and the unloading volume of concrete is smaller. Conversely, when the winding rotating shaft drives the unloading swing arm to rotate a large arc length, the opening formed by the sealing arc plate at the bottom of the vertical unloading cylinder is larger, and the unloading volume of concrete is larger. The unloading volume is reduced for locations with a large concrete paving volume, and the unloading volume is increased for locations with a small concrete paving volume, which facilitates construction. (2) Start the reciprocating drive motor, rotate the rocker arm to rotate, and drive the rotating ring to swing through the protruding part, thereby driving the vibrating feeder to vibrate back and forth through the bottom connecting frame. The four sets of side swing arms help the vibrating feeder to vibrate, thereby processing the lumps in the concrete and intercepting the lumps in the concrete. Attached Figure Description

[0020] like Figures 1-2As shown, the present invention provides a concrete paving and conveying machine for roads and bridges, including a paving and unloading control component 2, a vibration mechanism 1, an unloading guide hopper 3, a bottom support frame 4, a bottom guide rail 5, and a guide wheel 6.

The vibration mechanism 1 is disposed on the bottom support frame 4, the unloading guide hopper 3 is disposed on the bottom support frame 4, and the paving and unloading control component 2 is disposed on the unloading guide hopper 3. This invention can solve the problem of uneven paving volume during the paving and conveying of concrete for roads and bridges.

[0021] like Figure 2 and Figures 5-7 As shown, the paving and unloading control assembly 2 includes a paving and unloading motor 7, a receiving sleeve 8, a fixed guide housing 9, a bottom connecting rod 10, a lightweight disc 11, a winding rotating shaft 12, an unloading swing rod 13, a sealing arc plate 14, an unloading frame 15, and an unloading operation trough 16. The unloading frame 15 is mounted on the unloading guide hopper 3, and the unloading operation trough 16 is arranged in two groups on the unloading frame 15. The bottom of the unloading guide hopper 3 is connected to a vertical unloading cylinder 17, which has an open bottom. The winding rotating shaft 12 is rotatably mounted on the vertical unloading cylinder 17 and the unloading frame 15. The unloading swing rod 13 is mounted on the unloading guide hopper 3. The paving and unloading motor 7 is mounted on the outer wall of the unloading frame 15. The output end of the paving and unloading motor 7 is connected to the winding and rotating shaft 12. The receiving sleeve 8 is spirally wound on the end of the winding and rotating shaft 12. The fixed guide shell 9 is fixed on the outer wall of the unloading frame 15. The receiving sleeve 8 is vertically slidably mounted in the fixed guide shell 9. The bottom connecting rod 10 is located at the bottom of the receiving sleeve 8. The lightweight disc 11 is located on the bottom connecting rod 10. The lightweight disc 11 can contact the object with its bottom.

[0022] like Figures 5-8 As shown, the bottom end face of the lightweight disc 11 is provided with a motor touch switch 18 and a hardened touch switch 19. The motor touch switch 18 and the hardened touch switch 19 can trigger the internal circuit after contacting an object. The interior of the receiving sleeve 8 is filled with electrorheological fluid 20. Parallel plate capacitors 21 are embedded on the inner wall of the receiving sleeve 8. The parallel plate capacitors 21 are arranged in pairs between the inner walls of the receiving sleeve 8. The hardened touch switch 19 and the parallel plate capacitors 21 are electrically connected. The motor touch switch 18 and the paving and unloading motor 7 are electrically connected.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, the vibration mechanism 1 includes a reciprocating drive motor 22, a rotating rocker arm 23, a protruding part 24, a rotating ring 25, and a vibration rotating bracket 26. The body of the reciprocating drive motor 22 is mounted on the bottom support frame 4. The vibration rotating bracket 26 is fixedly connected to the bottom support frame 4. The rotating rocker arm 23 is rotatably mounted between the vibration rotating brackets 26. The output end of the reciprocating drive motor 22 is connected to the rotating rocker arm 23. The protruding part 24 is located in the middle section of the rotating rocker arm 23. The rotating ring 25 is rotatably sleeved on the protruding part 24.

[0024] like Figures 1-3 As shown, a side swing rod 27 is rotatably mounted on the bottom support frame 4. There are four sets of side swing rods 27, and a vibrating feeder 28 is mounted on each of the four sets of side swing rods 27. The vibrating feeder 28 is equipped with a sieve hole 29, which can intercept the lumps in the concrete and improve the quality of the treated concrete.

[0025] like Figures 2-4 As shown, one end of the vibrating feeder 28 is provided with a feed port 30, and the bottom of the vibrating feeder 28 is hinged with a bottom connecting frame 31, which is connected to the rotating ring 25.

[0026] like Figures 5-7 As shown, there are two sets of receiving sleeves 8, lightweight discs 11, motor touch switches 18 and hardened touch switches 19. The two sets of receiving sleeves 8 can control the concrete discharge volume of the two sets of vertical discharge cylinders 17 through the motor touch switches 18 and hardened touch switches 19 respectively. The sealing arc plate 14 can rotate to fit the bottom opening of the vertical discharge cylinder 17 and can seal the bottom of the vertical discharge cylinder 17 in the initial state.

[0027] like Figures 1-3 As shown, the vibrating feeder 28 and the unloading guide hopper 3 are corresponding in the vertical direction.

[0028] In practical use, bottom guide rails 5 are set up on both sides of the concrete construction site. The bottom support frame 4 is pushed so that the guide wheel 6 slides on the bottom guide rail 5, thereby cooperating with the equipment to spread and convey concrete. The reciprocating drive motor 22 is started, and the rocker arm 23 is rotated. The protruding part 24 drives the rotating ring 25 to swing, thereby driving the vibrating feeder 28 to vibrate back and forth through the bottom connecting frame 31. The four sets of side swing rods 27 help the vibrating feeder 28 to vibrate, thereby processing the lumps in the concrete and intercepting the lumps in the concrete. After being processed by the vibration mechanism 1, the concrete enters the unloading guide hopper 3 through the screen holes 29. In the initial state, the sealing arc plate 14 completely blocks the vertical unloading cylinder 17, thus sealing the bottom of the vertical unloading cylinder 17. The concrete is temporarily stored in the vertical unloading cylinder 17. After the paving and unloading motor 7 is started, the output end of the paving and unloading motor 7 rotates counterclockwise, causing the receiving sleeve 8 to move accordingly. As a result, the receiving sleeve 8 slides downward along the fixed guide shell 9. The bottom connecting rod 10 can maintain the stable downward sliding of the receiving sleeve 8, and the lightweight disc 11 moves downward accordingly. When the lightweight disc 11 comes into contact with the concrete being paved at the bridge construction site or with the ground, the motor touch switch 18 and the hardened touch switch 19 will be triggered. Since there are two sets of motor touch switches 18 and hardened touch switches 19, each set detects the amount of concrete paved around the two sets of lightweight discs 11. If there is concrete below the lightweight disc 11, the lightweight disc 11 will contact the concrete first. At this time, the length of the receiving sleeve 8 is shorter, and the motor touch switch 18 and the hardened touch switch 19 will be triggered. 19 triggers the internal circuitry, stopping the paving and unloading motor 7 and causing the parallel plate capacitors 21 to discharge. The electrorheological fluid 20 changes from liquid to solid, and the entire receiving sleeve 8 becomes rigid and stable. The solidified electrorheological fluid 20 prevents the receiving sleeve 8 from continuing to move downward, thus keeping the winding shaft 12 stationary. Therefore, the arc length of the unloading swing arm 13 driven by the winding shaft 12 is smaller, resulting in a smaller opening formed by the sealing arc plate 14 at the bottom of the vertical unloading cylinder 17, and thus a smaller amount of concrete is unloaded. If there is no concrete or the amount of concrete below the lightweight disc 11 is small, the length of the lowered sleeve 8 will be longer. In this case, the arc length of the rotation of the winding shaft 12 and the unloading swing rod 13 will be larger, which will cause the sealing arc plate 14 to form a larger opening at the bottom of the vertical unloading cylinder 17. At this time, the amount of concrete unloaded will be larger. Thus, the amount of concrete unloaded can be automatically controlled according to the original amount of concrete paving at the construction location. The unloading amount will be reduced for locations with a large amount of concrete paving and increased for locations with a small amount of concrete paving, which will facilitate construction.
