Description

Technical Field

[0001] This utility model relates to the field of slope paving construction, and in particular to a device for slope concrete paving. Background Technology

[0002] Existing ramp paving methods use chutes to transport concrete from the upper to the lower level of the ramp. However, ramps are often long, requiring the concrete to pass through extended chutes. Since aggregates and mortar in the concrete have different densities, during the descent, due to gravity and inertia, denser aggregates accelerate faster and move ahead, causing aggregates to concentrate at the bottom or front of the chute, while mortar remains at the top or rear, resulting in a segregated state of "aggregate accumulation and mortar deficiency." After segregation, coarse aggregates tend to deposit at the bottom of the chute. If the chute slope is uneven or has gentle sections, aggregate jamming can occur, potentially causing blockages during subsequent concrete delivery and disrupting the transport process.

[0003] The intense impact and vibration during the descent cause air bubbles that were originally evenly distributed in the concrete to escape or aggregate, reducing its density. Aggregates (especially coarse aggregates) in the concrete continuously erode the inner wall of the chute during high-speed descent, leading to wear and deformation over time, requiring regular replacement or repair and increasing equipment maintenance costs. Therefore, we propose a slope concrete paving device to address these issues. Utility Model Content

[0004] This utility model provides a concrete paving device for slopes, which solves the problems of concrete transported by chute on slopes, where aggregates concentrate at the bottom or front of the chute during long-term transport, while mortar remains at the top or rear, causing concrete segregation; aggregate jamming and interruption of transport during chute transport; and wear and deformation of the chute after long-term use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a concrete paving device for slopes, including an upper plane and a lower plane, with an inclined panel between the upper plane and the lower plane, a receiving box, two first winches and two second winches on the upper plane, a material transfer vehicle on one side of the receiving box, a funnel on the receiving box, a sliding paver on the inclined panel, and a second receiving hopper connected at both ends of the paver.

[0006] In the preferred embodiment, side templates are provided on both sides of the inclined panel, and inner grooves are provided on both sides of the bottom of the paver. The side templates abut against the inner grooves. Connecting plates are provided on both sides of the bottom of the paver. The second winch includes a second steel cable, and the connecting plates are connected to the second steel cable.

[0007] In a preferred embodiment, the receiving box includes a support frame, a funnel on the support frame, and a discharge device on the funnel. The discharge device includes an arc-shaped rotating plate and a first motor.

[0008] In the preferred embodiment, a main gear is provided at one end of the first motor, and a meshing driven gear is provided on the main gear. The first motor is mounted on the side unloading frame.

[0009] In a preferred embodiment, the arc-shaped rotating plate includes an arc-shaped baffle, side plates on both sides of the arc-shaped baffle, and rotating sleeves on the side plates. The rotating sleeves are rotatably connected to the side unloading frame, and a gear is installed on one of the rotating sleeves.

[0010] In the preferred embodiment, the material transfer vehicle is equipped with a receiving hopper, the first winch includes a first steel cable, the first steel cable is connected to the material transfer vehicle, the bottom of the material transfer vehicle is equipped with a support rod, one end of the support rod is equipped with a limiting ring, and the second steel cable passes through the limiting ring.

[0011] In the preferred embodiment, a second unloading device is provided on one side of the receiving hopper, and the second unloading device has the same structure as the unloading device.

[0012] In the preferred embodiment, a mixer truck dump truck is installed on one side of the receiving box.

[0013] In the preferred embodiment, bottom slab reinforcement is provided between the two side formworks.

[0014] The beneficial effects of this utility model are as follows: This device transports concrete to the receiving box via a mixer truck and a dump truck. By opening and closing the unloading device, the receiving box transports the concrete to the transfer vehicle. By driving the first winch, the transfer vehicle moves between the receiving box and the paver. By driving the second unloading device, the transfer vehicle transports the concrete to the second receiving hopper. The second receiving hopper is connected to the paver, and the paver spreads the concrete on the inclined panel.

[0015] This device drives a second winch to slide the paver relative to the side formwork, allowing the paver to move up the slope. The second winch's second cable passes through a limiting ring at the bottom of the material transfer trolley, thus limiting the trolley's movement and preventing it from veering off course as it moves from the upper plane to the lower plane near the paver. This ensures accurate unloading of material from the trolley into the second receiving hopper. The second winch not only controls the paver's movement up and down the slope but also limits the movement of the material transfer trolley.

[0016] The first motor of the unloading device is driven to rotate the main gear, which in turn rotates the driven gear, causing the arc-shaped rotating plate to rotate relative to the funnel, thereby unloading the material. The rotation angle of the first motor is adjusted to regulate the opening size of the arc-shaped rotating plate relative to the unloading port of the funnel, thus regulating the unloading speed of the concrete.

[0017] The overall structure uses a transfer vehicle to transport concrete, which avoids the concrete segregation and chute blockage caused by chute transportation. It also avoids the wear and deformation of the chute over long-term use, which would require regular replacement or repair and increase equipment maintenance costs. Therefore, it has great potential for widespread adoption. Attached Figure Description

[0027] Example 1:

[0028] like Figure 1-7The device for paving concrete on slopes includes an upper plane and a lower plane, with an inclined panel 1 between them. The upper plane is equipped with a receiving hopper 3, two first winches 8, and two second winches 9. A transfer cart 4 is located on one side of the receiving hopper 3, and a funnel 302 is mounted on the receiving hopper 3. A sliding paver 6 is mounted on the inclined panel 1, with second receiving hoppers 7 connected to both ends of the paver 6. With this structure, the device transports concrete to the receiving hopper 3 via a mixer truck dump truck 10. The receiving hopper 3 transports the concrete to the transfer cart 4 via an opening and closing unloading device 5. The transfer cart 4 moves between the receiving hopper 3 and the paver 6 by driving the first winches 8. The transfer cart 4 transports the concrete to the second receiving hoppers 7 by driving the second unloading device 12. The second receiving hoppers 7 are connected to the paver 6, which then spreads the concrete onto the inclined panel 1.

[0029] This device drives a second winch 9 to slide the paver 6 relative to the side formwork 2, allowing the paver 6 to move on the slope. The second steel cable 901 of the second winch 9 passes through a limiting ring 403 at the bottom of the material transfer trolley 4, thus limiting the material transfer trolley 4 and preventing it from veering off course as it moves from the upper plane to the lower plane near the paver 6. This ensures accurate unloading of material from the material transfer trolley 4 onto the second receiving hopper 7. The second winch 9 not only controls the paver 6's movement up and down the slope but also limits the movement of the material transfer trolley 4.

[0030] The first motor 502 of the unloading device 5 is driven to rotate the main gear 503, which in turn rotates the driven gear 504, causing the arc-shaped rotating plate 501 to rotate relative to the funnel 302, thereby unloading the material. The rotation angle of the first motor 502 is adjusted to regulate the opening size of the arc-shaped rotating plate 501 relative to the unloading port of the funnel 302, thereby regulating the unloading speed of the concrete.

[0031] The overall structure uses a material transfer vehicle 4 to transport concrete, which avoids the concrete segregation and chute blockage caused by chute transportation. It also avoids the wear and deformation of the chute after long-term use, which would require regular replacement or repair and increase equipment maintenance costs.

[0032] In the preferred embodiment, side templates 2 are provided on both sides of the inclined panel 1, and inner grooves are provided on both sides of the bottom of the paver 6. The side templates 2 abut against the inner grooves. Connecting plates 601 are provided on both sides of the bottom of the paver 6. The second winch 9 includes a second steel cable 901, and the connecting plates 601 are connected to the second steel cable 901. With this structure, the paver 6 includes a double-helix concrete conveyor. Both ends of the paver 6 are connected to the second receiving hopper 7, and a conveyor motor is provided on one side of the paver 6. The top of the second receiving hopper 7 is open, and the second receiving hopper 7 is parallel to the side templates 2.

[0033] In a preferred embodiment, the receiving box 3 includes a support 301, a funnel 302 mounted on the support 301, and a discharge device 5 mounted on the funnel 302. The discharge device 5 includes an arc-shaped rotating plate 501 and a first motor 502. With this structure, the mixer truck dump truck 10 transports concrete into the receiving box 3, and by opening and closing the discharge device 5, the receiving box 3 transports the concrete to the transfer truck 4.

[0034] In a preferred embodiment, the first motor 502 has a main gear 503 at one end, and a meshing driven gear 504 on the main gear 503. The first motor 502 is mounted on the side discharge frame 403. With this structure, the first motor 502 of the discharge device 5 is driven to rotate the main gear 503, which in turn rotates the driven gear 504, causing the arc-shaped rotating plate 501 to rotate relative to the funnel 302.

[0035] In a preferred embodiment, the arc-shaped rotating plate 501 includes an arc-shaped baffle 5011, with side plates 5012 on both sides of the arc-shaped baffle 5011. A rotating sleeve 5013 is mounted on each side plate 5012, and the rotating sleeve 5013 is rotatably connected to the side unloading frame 403. A gear 504 is mounted on one of the rotating sleeves 5013. With this structure, the first motor 502 of the unloading device 5 is driven to unload the material. By adjusting the rotation angle of the first motor 502, the opening size of the arc-shaped rotating plate 501 relative to the unloading port of the funnel 302 is adjusted, thereby regulating the unloading speed of the concrete.

[0036] In a preferred embodiment, the material transfer trolley 4 is equipped with a receiving hopper 401. The first winch 8 includes a first steel cable 801 connected to the material transfer trolley 4. A support rod 402 is located at the bottom of the material transfer trolley 4, with a limiting ring 403 at one end. A second steel cable 901 passes through the limiting ring 403. With this structure, the second steel cable 901 of the second winch 9 passes through the limiting ring 403 at the bottom of the material transfer trolley 4, thus limiting the material transfer trolley 4. This prevents the material transfer trolley 4 from veering off course when moving from the upper plane to the lower plane near the paver 6, ensuring accurate unloading of material from the material transfer trolley 4 onto the second receiving hopper 7. The second winch 9 not only controls the movement of the paver 6 up and down the slope but also limits the movement of the material transfer trolley 4.

[0037] In a preferred embodiment, a second unloading device 12 is provided on one side of the receiving hopper 401. The second unloading device 12 has the same structure as the unloading device 5. With this structure, the second unloading device 12 is identical to the unloading device 5. By controlling the second unloading device 12, the concrete on the material transfer vehicle 4 is transported to the second receiving hopper 7.

[0038] In the preferred embodiment, a mixer truck 10 is installed on one side of the receiving bin 3. This structure allows the mixer truck 10 to mix concrete in real time, preventing segregation that can occur when concrete is not mixed for extended periods during sloping paving.

[0039] In the preferred embodiment, a bottom plate reinforcement 11 is provided between the two side formworks 2. With this structure, the bottom plate reinforcement 11 is located at the bottom of the inclined panel 1.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
