Description

Technical Field

[0001] This utility model relates to the field of paving construction material transportation technology, and more specifically, to a conveying device for paving construction materials of water-stabilized base course. Background Technology

[0002] In the construction of infrastructure such as highways and municipal roads, the water-stabilized base course is a key load-bearing layer in the pavement structure, and its construction quality directly affects the overall strength, stability, and service life of the road. The water-stabilized base course is typically formed by mixing raw materials such as cement, fly ash, and graded crushed stone in a certain proportion, followed by paving and compaction. Because the water-stabilized mixture has a certain initial setting time after mixing, if the transportation process is interrupted or the material segregates, it will lead to paving work stagnation and failure of the initial setting of the mixture. This not only affects construction efficiency but also causes quality problems such as uneven base course strength and cracking.

[0003] The paver is equipped with a material feeding hopper. In the construction of water-stabilized base course, the material is usually fed to the paver by a transport vehicle. However, this method is less efficient and more suitable for small and medium-sized projects. Each time the material is added, the transport vehicle needs to be aligned and unloaded, which is time-consuming. Moreover, the loading capacity of a single transport vehicle is limited. For large-scale projects such as highways, frequent material additions will seriously slow down the construction progress and increase the construction period and cost. If the transport vehicle does not unload in time or the gap between the two vehicles is too long, the material hopper of the paver may "break down", causing the paving operation to be suspended. After restarting, "cold joints" or height differences are easily formed between the new and old materials, affecting the flatness and integrity of the water-stabilized base course, and thus increasing the risk of road surface cracking in the later stage.

[0004] Therefore, this utility model provides a conveying device for the construction materials of water-stabilized base course paving to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a conveying device for water-stabilized base paving construction materials, which has the advantage of being able to continuously supply materials to the paving vehicle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conveying device for water-stabilized base course paving construction materials, comprising a transport frame A, a conveying mechanism A fixedly mounted on the transport frame A, a connecting mechanism A for connecting the transport frame A and the material conveying hopper of the paver, and a supporting mechanism mounted on the transport frame A for supporting the materials. The conveying mechanism A includes a drive roller A, a conveyor belt A sleeved on the drive roller A, and a drive motor A fixedly mounted on the side of the transport frame A. One end of the drive roller A passes through the transport frame A and is fixedly connected to the output end of the drive motor A. The connecting mechanism A includes a fixed plate fixedly mounted on the material conveying hopper, a rotating plate A rotatably connected to the fixed plate, and a hinge plate A hinged to the side of the rotating plate A away from the material conveying hopper. The hinge plate A is fixedly mounted at the bottom of the transport frame A at one end corresponding to the conveying direction.

[0007] As a preferred technical solution of this utility model, the support mechanism includes a rotating component rotatably connected to both sides of the transport frame A, a hydraulic telescopic rod fixedly disposed at one end of the rotating component, and a sleeve movably connected to the paver body. The end of the sleeve away from the paver body is threadedly connected to the output end of the hydraulic telescopic rod.

[0008] As a preferred embodiment of this utility model, the rotating plate A is threadedly connected with a plurality of threaded rods, one end of which passes through the rotating plate A and abuts against the fixed plate.

[0009] As a preferred embodiment of this utility model, a transport frame B is provided on the transport frame A, and a conveying mechanism B is installed on the transport frame B.

[0010] As a preferred embodiment of the present invention, the conveying mechanism B includes a drive roller B, a conveyor belt B sleeved on the drive roller B, and a drive motor B fixedly disposed on the side of the transport frame B. One end of the drive roller B passes through the transport frame B and is fixedly connected to the output end of the drive motor B.

[0011] As a preferred technical solution of this utility model, a connecting mechanism B is provided between the transport frame A and the transport frame B. The connecting mechanism B includes a sliding plate with both ends slidably disposed on the transport frame A, a rotating plate B rotatably disposed on the sliding plate, a hinge plate B hinged to the rotating plate B at the end opposite to the conveying direction, and a hinge plate C hinged to the hinge plate B at the end corresponding to the conveying direction. The hinge plate C is fixedly connected to the bottom surface of the transport frame B at the end corresponding to the conveying direction.

[0012] As a preferred embodiment of this utility model, several push plates are respectively arrayed on conveyor belt A and conveyor belt B.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model sets up a hinge plate A, rotates the hinge plate A to lift the other end of the transport frame A to a suitable angle, and then rotates the rotating plate A to adjust the horizontal angle of the transport frame A, so that the transport frame A is set up at one end of the outlet of the concrete mixer truck, and the conveyor belt A catches the concrete at the outlet end, so as to realize the continuous transfer of materials between the concrete mixer truck and the paver, reducing the interruption and segregation in the intermediate links.

[0015] 2. This utility model uses a threaded rod. After adjusting the position of the transport frame A, the threaded rod is tightened to fix the horizontal angle of the transport frame A. Then, by rotating the rotating part, the hydraulic telescopic rod is controlled to extend to a suitable length. The output end of the hydraulic telescopic rod is threadedly connected to the sleeve to support the transport frame A.

[0016] 3. By setting a sliding plate, when the material inlet of the concrete mixer is too far from the material inlet of the paver, the sliding plate is slid to move the connecting mechanism B to the end of the transport frame A close to the concrete mixer. At this time, the transport frame A and the transport frame B are connected end to end, and the conveying mechanism B is above the conveying mechanism A. The material can fall directly from the conveying mechanism B onto the conveying mechanism A for continuous conveying, which increases the overall conveying distance of the conveying device. The angle of the transport frame B can be adjusted by rotating the rotating plate B, the hinge plate B, and the hinge plate C to adapt to the discharge port of the concrete mixer truck at different heights and positions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, this utility model provides a conveying device for water-stabilized base course paving construction materials, including a transport frame A1, a conveying mechanism A2 fixedly mounted on the transport frame A1, a connecting mechanism A3 for connecting the transport frame A1 and the material conveying hopper of the paver, and a support mechanism 4 mounted on the transport frame A1 for supporting the material. The conveying mechanism A2 includes a drive roller A21, a conveyor belt A22 sleeved on the drive roller A21, and a drive motor A23 fixedly mounted on the side of the transport frame A1. One end of the drive roller A21 passes through the transport frame A1 and outputs power to the drive motor A23. The connection mechanism A3 includes a fixed plate 31 fixedly mounted on the conveying funnel, a rotating plate A32 rotatably connected to the fixed plate 31, and a hinge plate A33 hinged to the side of the rotating plate A32 away from the conveying funnel. The hinge plate A33 is fixedly mounted at the bottom of the transport frame A1 at one end corresponding to the conveying direction. When the paver is working, the hinge plate A33 is rotated to lift the other end of the transport frame A1 to a suitable angle. Then, the rotating plate A32 is rotated to adjust the horizontal angle of the transport frame A1, and the transport frame A1 is erected at one end of the concrete mixer truck's outlet. The conveyor belt A22 receives the concrete at the outlet end.

[0026] Furthermore, refer to Figures 1 to 6The support mechanism 4 includes a rotating component 41 rotatably connected to both sides of the transport frame A1, a hydraulic telescopic rod 42 fixedly installed at one end of the rotating component 41, and a sleeve 43 movably connected to the paver body. The end of the sleeve 43 away from the paver body is threadedly connected to the output end of the hydraulic telescopic rod 42. The output end of the hydraulic telescopic rod 42 is threadedly connected to the sleeve 43. The hydraulic telescopic rod 42 is extended to a suitable length to support the transport frame A1.

[0027] Furthermore, refer to Figures 1 to 6 The rotating plate A32 is threaded with several threaded rods 321. One end of each threaded rod 321 passes through the rotating plate A32 and abuts against the fixed plate 31. To prevent the transport frame A1 from shaking and causing damage, the threaded rods 321 are tightened after the position is adjusted to fix the angle of the transport frame A1.

[0028] It is worth noting that, referring to Figures 1 to 6 The transport frame A1 is provided with a transport frame B5, and the transport frame B5 is equipped with a conveying mechanism B6, which can increase the conveying distance and make the overall conveying device more flexible.

[0029] It should be noted that, referring to Figures 1 to 6 The conveying mechanism B6 includes a drive roller B61, a conveyor belt B62 sleeved on the drive roller B61, and a drive motor B63 fixedly installed on the side of the transport frame B5. One end of the drive roller B61 passes through the transport frame B5 and is fixedly connected to the output end of the drive motor B63. The drive motor B63 drives the drive roller B61 to rotate, thereby driving the conveyor belt B62 to run.

[0030] Among them, reference Figures 1 to 6 A connecting mechanism B7 is provided between the transport frame A1 and the transport frame B5. The connecting mechanism B7 includes a sliding plate 71 with both ends slidably disposed on the transport frame A1, a rotating plate B72 rotatably disposed on the sliding plate 71, a hinge plate B73 hinged to the rotating plate B72 at the end opposite to the conveying direction, and a hinge plate C74 hinged to the hinge plate B73 at the end corresponding to the conveying direction. The hinge plate C74 is fixedly connected to the bottom surface of the transport frame B5 at the end corresponding to the conveying direction. The angle of the transport frame B5 can be adjusted individually by rotating the rotating plate B72, the hinge plate B73, and the hinge plate C74 to adapt to the discharge port of the concrete mixer truck at different heights and positions.

[0031] Furthermore, refer to Figures 1 to 6Several push plates 8 are arrayed on the conveyor belts A22 and B62 respectively. When the conveyor belts A22 and B62 are tilted, the push plates 8 can move the material more effectively and prevent the material from sliding.

[0032] Working principle and usage process of this utility model:

[0033] The conveying device is installed on the paver's feed hopper. When the paver is not in operation, the hinge plate A33 and the rotating plate A32 are approximately perpendicular, facilitating placement and saving space. When the paver is in operation, rotating the hinge plate A33 raises the other end of the transport frame A1 to a suitable angle. Then, rotating the rotating plate A32 adjusts the horizontal angle of the transport frame A1, placing it at the outlet end of the concrete mixer truck. The conveyor belt A22 catches the concrete at the outlet end. The transport frame A1 needs to span the distance between the paver and the concrete mixer truck, requiring a relatively long length. To prevent damage caused by swaying, after adjusting the position, tighten the threaded rod 321 to fix the horizontal angle of the transport frame A1. The hydraulic telescopic rod 42 is externally connected to a hydraulic pump (model SQP3-35-1B-18) as the power system. Rotating the rotating component 41 controls the hydraulic telescopic rod 42 to extend to a suitable length. The output end of the hydraulic telescopic rod 42 is threadedly connected to the sleeve 43 to support the transport frame. A1. If the material inlet of the concrete mixer is too far from the feed hopper of the paver, slide the sliding plate 71 to move the connecting mechanism B7 to the end of the transport frame A1 closer to the concrete mixer. At this time, the transport frame A1 and the transport frame B5 are connected end to end. The conveying mechanism B6 is above the conveying mechanism A2. The material can fall directly from the conveying mechanism B6 onto the conveying mechanism A2 for continuous conveying, which increases the overall conveying distance of the conveying device. The angle of the transport frame B5 can be adjusted individually by rotating the rotating plate B72, the hinge plate B73, and the hinge plate C74 to adapt to the discharge ports of concrete mixer trucks of different heights and positions. The drive motors A23 and B63 are connected to a 380V AC power supply, which drives the drive rollers A21 and B61 to rotate, and then drives the conveyor belts A22 and B62 to run. The push plates 8 on the conveyor belts A22 and B62 can move the material more effectively when the conveyor belts A22 and B62 are tilted, preventing the material from sliding.
