Description

Technical Field

[0001] The invention relates to the technical field of concrete construction, and in particular to a concrete spreading device for civil engineering. Background Art

[0002] In the process of laying cement pavement for high-grade highways, urban and rural roads, airports, docks, etc., in order to ensure the flatness of cement filling, cement concrete paving machines have become one of the indispensable and important equipment. At present, the paving machines commonly used in civil engineering are generally driven by tractors or other mobile equipment, moving along the predetermined paving road surface. At the same time, the concrete transport truck moving in parallel with the paving machine is responsible for continuously feeding materials to the paving machine or in front of it, and the paving machine then completes the concrete paving operation.

[0003] The paving frames of existing paving machines are generally divided into two types: silo type and open type. The silo type paving frame is a concrete paving frame in which concrete is poured into the silo of the paving machine by a concrete transport vehicle, and the concrete is transported to the bottom of the paving frame through the silo for paving. For example, Chinese Patent Publication No. CN112726334B discloses a concrete paving machine for civil engineering, which includes a chassis, a fixed cylinder and a rotating cylinder. A feeding auger is connected to the fixed cylinder, and a rotating cylinder rotatably mounted on the chassis is provided on the outside of the fixed cylinder. Two paving assemblies are provided at the bottom of the chassis corresponding to the fixed cylinder, and a rolling roller is provided on one side of the paving assembly. The patent realizes intermittent alignment of the circulation trough with the discharge trough and the feed trough through the rotation of the rotating cylinder, thereby realizing intermittent loading in the fixed cylinder and intermittent unloading at the bottom, avoiding the problem of workers manually pushing the unloading vehicle to fill the material, and improving work efficiency. However, the structure of the device is relatively complex, which increases the difficulty of maintenance and cleaning. In addition, the carrying capacity of the fixed cylinder is limited, and the concrete transport vehicle and the paving machine still need to move in parallel for continuous feeding. The structure of the open paving frame is mostly a U-shaped structure. The concrete transport truck directly dumps the concrete into the U-shaped frame of the paving frame, and the concrete is laid as the paving frame is pushed. The baffles on both sides of the paving frame prevent the problem of concrete overflowing during paving to a certain extent. However, in actual operation, when the paving frame pushes the concrete, although the baffles are set, the concrete will still overflow from the baffles. In order to solve this problem, the staff needs to manually shovel the overflowed concrete back to the center of the paving frame, or the driver needs to reduce the speed of the paving equipment and wait for the spiral spreader to adjust the concrete to ensure the uniform distribution of the concrete. This treatment method not only increases the frequency of manual intervention, but also significantly reduces the overall efficiency of road paving. Summary of the invention

At the same time, the two guide plates form a V-shaped inlet, which can guide the concrete in front of the paving machine and further guide the concrete to flow to the center of the paving frame. Through this adjustment, it is ensured that the concrete is always evenly distributed. In order to ensure the guiding effect of the guide plate, the flow of concrete can be further promoted through the guide assembly to increase the flow rate of the concrete.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

At this time, the excess concrete flows back along the inner wall of the guide plate to the center of the paving frame, realizing circular transportation and uniform paving.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 5 As shown: a concrete paving device for civil engineering projects, comprising a paving frame 1 and baffles 11 arranged on both sides of the paving frame 1, a spiral distribution assembly 12 is arranged in the paving frame 1, which can drive concrete to move to the baffles 11 on both sides; a guide plate 13 is arranged on the end of the two baffles 11 of the paving frame 1 away from the spiral distribution assembly 12, one end of the guide plate 13 is hinged to the end of the baffle 11, and a guide assembly 131 that can push concrete is arranged on the side of the guide plate 13 close to the baffle 11; in the initial state, the guide plate 13 and the baffle 11 are parallel to each other; when working, the guide plate 13 rotates around the hinge point between the guide plate 13 and the baffle 11, so that the guide plate 13 is arranged on the baffle 11 at an angle, and cooperates with the start of the guide assembly 131 to push the excess concrete on the baffle 11 side to the center of the paving frame 1.

[0033] When the paving device is working, the concrete is poured between the baffles 11 on both sides of the paving frame 1 through a concrete transport truck. When the paving frame 1 moves, it will push the concrete, and the concrete will naturally move to both sides under the extrusion. In order to improve the uniformity of paving, the device is equipped with a spiral feeding assembly 12, which can further evenly transport the concrete to both sides to achieve efficient paving operations. However, when the concrete transport truck feeds too much, some concrete will accumulate on the side of the baffle 11. Although the baffle 11 can prevent this part of the concrete from overflowing, when the accumulation is too much, the concrete may still overflow from the end of the baffle 11, and the excess concrete needs to be manually shoveled back to the center of the paving frame 1. (The arrow in the figure indicates the flow direction of the concrete)

[0034] In order to solve the above problems, by setting the guide plate 13 and the guide assembly 131, when there is too much concrete accumulated on the side of the baffle 11, the guide plate 13 rotates around the hinge point with the baffle 11, so that the guide plate is installed on the baffle 11 in an inclined state. At this time, the excess concrete flows back to the center of the paving frame 1 along the inner wall of the guide plate 13, realizing circular transportation and uniform paving. In addition, when the two guide plates 13 are both inclined, they form a V-shaped inlet, which has a diversion effect on the concrete in front of the paving machine, and further guides the concrete to flow to the central area of ​​the paving frame 1. Through this adjustment, it is ensured that the concrete is always evenly distributed, and efficient and stable paving operations are achieved. In order to ensure the diversion effect of the guide plate 13, the guide assembly 131 can further promote the flow of concrete and increase the flow rate of concrete.

[0035] The cooperation of the spiral material distribution assembly 12 and the guide plate 13 effectively solves the problem of concrete accumulation and overflow, makes the concrete evenly distributed in the paving frame 1, improves the paving quality, reduces the frequency of manual shoveling due to concrete overflow, and does not need to frequently reduce the paving speed or adjust the equipment operation, which significantly improves the overall work efficiency. At the same time, in the initial state, the guide plate 13 can be parallel to the baffle 11, so that it shrinks on the side of the baffle 11, which is convenient for the transportation of the equipment.

[0036] The V-shaped structure formed by the two guide plates 13 helps to guide the concrete in front of the paving frame 1 into the central area, optimizing the feeding and paving process. The adaptive material guiding function of the device enables it to cope with different feeding amounts and paving scenarios, and has a wider range of application adaptability.

[0037] like Figures 2 to 5 and Fig.10As shown: the material guide assembly 131 includes a mounting frame 1311, a conveyor belt 1313 and two rollers 1312. The mounting frame 1311 is fixedly connected to the side of the guide plate 13 close to the baffle 11. The two rollers 1312 are rotatably mounted on the mounting frame 1311. The transmission belt is sleeved on the two rollers 1312. The conveyor belt 1313 is provided with a plurality of scrapers 13131 equidistantly distributed along its contour.

[0038] By providing the mounting frame 1311, the conveyor belt 1313 and the roller 1312, the guide assembly 131 can realize effective flow diversion of concrete. The scraper 13131 on the conveyor belt 1313 can continuously push the redundant concrete, so that the concrete quickly returns to the center of the paving frame 1, avoiding the tedious manual adjustment.

[0039] The existence of the scraper 13131 can prevent excess concrete from overflowing or accumulating at the end of the baffle 11, ensuring that the concrete moves stably and evenly on the guide plate 13, further improving the distribution effect of concrete during the paving process, thereby improving the paving quality. The frequency of manual shoveling of concrete is significantly reduced, the labor intensity of the staff is reduced, and the construction efficiency is improved.

[0040] The provision of the material guide assembly 131 enables the material guide plate 13 to cope with working conditions of different feed amounts and concrete viscosities, which not only improves the adaptability of the device, but also enables stable operation in various complex construction scenarios.

[0041] The arrangement of the conveyor belt 1313 and the scraper 13131 facilitates daily maintenance and component replacement, thereby extending the service life of the equipment and reducing operating costs.

[0042] like Figures 2 to 5 and Fig.10 As shown, an extension plate 132 is provided on one end of the material guide plate 13 away from the spiral material distribution assembly 12 , and the extension plate 132 and the material guide plate 13 are perpendicular to each other.

[0043] Since the guide plate 13 is hingedly mounted on the baffle 11, after the guide plate 13 is rotated, there is a gap between the end of the guide plate 13 and the baffle 11. When the guide plate 13 guides the concrete, part of the concrete may flow out from the gap, and it is still necessary to manually shovel back the concrete that has flowed out. The extension plate 132 is vertically arranged to the guide plate 13, which effectively blocks the gap formed between the guide plate 13 and the baffle 11 after the rotation of the guide plate 13, prevents the concrete from flowing out of the gap, reduces the outflow of concrete, and guides the concrete to move more concentratedly to the center of the paving frame 1, further improving the diversion effect of the concrete, and contributing to the uniformity and quality of the paving process.

[0044] After the gap is sealed, there is no need to manually shovel back the outflowing concrete repeatedly, which reduces the labor intensity of operators and improves construction efficiency.

[0045] like Figures 2 to 6 and Fig.10 As shown: a driving assembly 133 for pushing the guide plate 13 is arranged on the outer side of the baffle 11, and the driving assembly 133 includes a driving block 1331 that can slide along the length direction of the baffle 11, and a connecting rod 13311 is arranged on the driving block 1331, and both ends of the connecting rod 13311 are respectively hinged to the driving block 1331 and the middle part of the mounting frame 1311.

[0046] The driving assembly 133 is installed on the outside of the baffle 11, and is used to push the guide plate 13 to move. The driving device of the driving block 1331 is preferably a hydraulic cylinder or a motor, so that the driving block 1331 can slide along the length direction of the baffle 11. The movement of the driving block 1331 drives the movement of the connecting rod 13311, so that the connecting rod 13311 can pull or push the mounting frame 1311, so that the guide plate 13 installed on the baffle 11 can rotate around its hinge point. By adjusting the sliding distance and direction of the driving block 1331, the inclination angle of the guide plate 13 can be accurately controlled, thereby realizing the adjustment and optimization of the concrete diversion path.

[0047] By setting the driving assembly 133, the inclination angle of the guide plate 13 can be automatically adjusted without manual intervention, greatly improving the convenience of operation and the intelligent level of the device. The precise sliding of the driving block 1331 controls the angle adjustment of the guide plate 13, so that the concrete can flow to the center of the paving frame 1 according to the set path, ensuring the stability and efficiency of the diversion process.

[0048] The angle of the guide plate 13 can be flexibly adjusted according to different working conditions such as the amount of concrete feed or construction conditions, to meet various construction requirements, and to improve the practicality and adaptability of the device. The automation level of the device is improved, the tedious steps of manually adjusting the guide plate 13 are avoided, and the workload of the operator is reduced.

[0049] like Figures 2 to 6 and Fig.10 As shown: the driving assembly 133 includes a first rotary driving motor 1332 and a screw rod 1333, the screw rod 1333 extends along the length direction of the baffle 11, the screw rod 1333 is rotatably installed on the outer side of the baffle 11, the first rotary driving motor 1332 is located on one end of the screw rod 1333, and the screw rod 1333 is transmission-connected to the first rotary driving motor 1332, and the driving block 1331 is sleeved on the screw rod 1333 and threadedly engaged with it.

[0050] When the first rotary drive motor 1332 is working, the output shaft of the first rotary drive motor 1332 drives the screw rod 1333 to rotate, and the rotation of the screw rod 1333 drives the driving block 1331 that cooperates with its thread, so that the driving block 1331 (the baffle 11 has a limit for the driving block 1331, which is not shown in the figure) slides along the length direction of the baffle 11, and the movement of the driving block 1331 drives the connecting rod 13311 to drive the guide plate 13, so that the guide plate 13 rotates around the hinge point between the guide plate 13 and the baffle 11, so that the inclination angle of the guide plate 13 can be adjusted.

[0051] Through the cooperation of the first rotary drive motor 1332 and the screw rod 1333, the inclination angle of the guide plate 13 can be automatically adjusted, replacing manual operation, thereby improving the automation level and operational convenience of the device. The screw rod 1333 driving structure has the characteristics of stable transmission and strong bearing capacity, ensuring that the guide plate 13 runs smoothly during the adjustment process and avoiding failures or deviations caused by impact or jamming. The screw rod 1333 transmission has a self-locking characteristic, which can ensure the stability of the structure of the guide plate 13 after being adjusted.

[0052] It should be noted that the angles of the two guide plates 13 can be adjusted separately according to actual needs without having to maintain the same angle. This independent adjustment can flexibly adapt to different stacking conditions when the concrete enters the paving frame 1. By independently adjusting the angles of the two guide plates 13, the position of the concrete entering the paving frame 1 can be more finely guided and adjusted, effectively avoiding the situation where the concrete is concentrated on one side or unevenly distributed, thereby further improving the effect of uniform paving of the concrete. While improving the overall quality of paving, it also enhances the adaptability of the device and the flexibility of operation.

[0053] like Figures 1 to 6 and Fig. 9 As shown: the spiral cloth assembly 12 includes two mirror-symmetrical spiral rods 121, the two spiral rods 121 are rotatably arranged on the spreading frame 1 in a horizontal state, and the two spiral rods 121 are coaxially arranged.

[0054] The two spiral rods 121 are arranged in mirror symmetry, and can evenly transport concrete from the center of the paving frame 1 to both sides by rotating in opposite directions, avoiding the phenomenon of unilateral accumulation or uneven distribution, and significantly improving the uniformity of paving. The coaxial arrangement of the two spiral rods 121 ensures the continuous transportation and efficient distribution of concrete, and improves the overall paving efficiency.

[0055] The coaxially mounted spiral rod 121 improves the balance and operational stability of the device, allowing the spiral spreading assembly 12 to adapt to the paving requirements in different construction environments and achieve precise concrete spreading effects through reasonable rotation speed and direction adjustment.

[0056] like Figures 1 to 6 and Fig. 9 As shown: a mounting plate 122 extending along the length direction of the baffle 11 is provided between the two spiral rods 121 on the paving frame 1, and a second rotary drive motor 123 is provided on one end of the two spiral rods 121 away from each other, and the spiral rods 121 are transmission-connected to the second rotary drive motor 123.

[0057] By setting a mounting plate 122 extending along the length direction of the baffle 11 between the two spiral rods 121, stable support and fixation are provided to ensure that the two spiral rods 121 run more smoothly, thereby improving the efficiency of concrete distribution. The far ends of the two spiral rods 121 are respectively equipped with a second rotary drive motor 123, which can achieve independent drive control. The spiral distribution assembly 12 can adjust the speed and direction of the spiral rods 121 on both sides according to the distribution of concrete during the paving process, further optimizing the uniform distribution effect of concrete. The independent configuration of the second rotary drive motor 123 can flexibly respond to different construction needs. Whether it is adjusting the speed or direction of the distribution, it can quickly adapt to various working conditions and improve the applicability of the equipment.

[0058] The arrangement of the mounting plate 122 structurally strengthens the fixation of the spiral rod 121, thereby avoiding deviation or error caused by vibration or imbalance during operation, thereby ensuring long-term stable operation of the equipment.

[0059] The second rotary drive motors 123 are dispersedly arranged at both ends of the spiral rod 121, which can effectively share the operating load and reduce the load pressure of a single drive motor, thereby extending the life of the equipment and reducing the failure rate.

[0060] like Figures 1 to 4 , Figure 7 and Fig. 9 As shown: a fixed frame is arranged above the paving frame 1, and a vibrating assembly 14 is arranged on the fixed frame. The vibrating assembly 14 includes a vibrating rod 141 installed in a vertical state on the paving frame 1, a third rotary drive motor 142 for driving the vibrating rod 141 to vibrate, and a flexible connecting pipe 1411 for connecting the vibrating rod 141 and the third rotary drive motor 142.

[0061] The vibrating assembly 14 drives the vibrating rod 141 to vibrate at high frequency through the third rotary drive motor 142. The third rotary drive motor 142 is connected to the vibrating rod 141 through a flexible connecting tube 1411. The setting of the flexible connecting tube 1411 enables the vibrating rod 141 to respond flexibly during the vibration process without being affected by the installation angle or slight deviation. When the paving frame 1 moves, the vibrating rod 141 applies a vibrating force to the concrete, discharges the bubbles in the concrete, and promotes the close combination of concrete particles, thereby improving the density and uniformity of the concrete.

[0062] Through the action of the vibrating assembly 14, the concrete can be evenly distributed, avoiding quality problems such as cracks or weakened strength due to insufficient density, thereby ensuring the overall effect of the construction.

[0063] Automated vibration replaces manual vibration operations, reducing the labor intensity of operators, improving construction efficiency, and reducing errors and unevenness caused by manual operations.

[0064] like Figures 1 to 4 , Figure 6 and Fig. 9 As shown: a rotatable support frame 143 is also provided on the vibrating assembly 14, a vibrating rod 141 is installed on the support frame 143, and a fourth rotary drive motor 1431 for driving the support frame 143 to rotate is provided on the outer side of the baffle 11. When the paving frame 1 moves, the support frame 143 will drive the vibrating rod 141 to lift up.

[0065] The support frame 143 is driven by the fourth rotary drive motor 1431, so that the vibrating rod 141 can be flexibly lifted or lowered. When the paving frame 1 encounters terrain undulations or obstacles, the vibrating rod 141 can be lifted to avoid damage to the equipment or disturbance of the concrete surface, thereby improving the adaptability and durability of the equipment. When the vibrating rod 141 does not need to vibrate (for example, when the paving frame 1 turns or stops), the vibrating rod 141 can be lifted by the support frame 143, thereby avoiding over-vibration or unnecessary wear caused by the vibrating rod 141 contacting the concrete surface for a long time, thereby ensuring the construction quality of the concrete.

[0066] The rotatable setting of the support frame 143 allows the position of the vibrating rod 141 to be adjusted according to construction requirements, ensuring that the vibrating rod 141 always acts on the target area, thereby improving the uniformity and density of concrete vibration. Through the lifting action, the need for manual intervention due to complex terrain or environment is reduced, the operational complexity of construction is reduced, and construction efficiency is improved. The vibrating rod 141 has greater flexibility under complex construction conditions. The wear caused by idling or ineffective vibration of the vibrating rod 141 is reduced, thereby extending the overall service life of the device. Energy waste is avoided, while reducing the operating load of the equipment.

[0067] like Figures 1 to 5 , Figures 7 to 9As shown in the figure: the bottom of the paving frame 1 is provided with a plurality of combing plates 16 which are evenly distributed along the length direction of the paving frame 1, and a trowel plate 15 which can vibrate in the vertical direction is provided on the side of the combing plate 16, and a plurality of guide plates 151 which are evenly distributed along the length direction thereof are provided on the trowel plate 15, and the plurality of guide plates 151 extend in the vertical direction, and the plurality of guide plates 151 are slidably matched with the paving frame 1, and a rotatable turntable 152 is provided on both sides of the paving frame 1, and a rotary plate 152 is provided on the turntable 152 There is a fixed shaft 1521 parallel to its axis, and a transmission rod 1522 hinged to it is arranged on the fixed shaft 1521. A support shaft 1511 parallel to the trowel plate 15 is arranged on the guide plate 151. The support shaft 1511 is sleeved on multiple guide plates, and both ends of the support shaft 1511 are respectively hinged to the ends of the transmission rod 1522 on the two turntables 152, and a fifth rotation drive motor 153 for driving the turntable 152 to rotate is arranged on the outer wall of the baffle 11.

[0068] The combing plates 16 are evenly distributed along the length of the paving frame 1.
