Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a device suitable for widening and paving asphalt pavements. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by incorporating road asphalt materials into mineral materials. Asphalt binders improve the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable pavement. The construction of asphalt pavement requires the use of pavers for spreading, pre-compacting, and other operations.

[0003] For road widening projects, traditional pavers need to be installed with hydraulic telescopic screeds or multiple machines spliced ​​together to complete the widening paving. Hydraulic telescopic screeds are expensive, and their internal parts are prone to damage during prolonged extension and contraction. If damage occurs, the repair time is long, during which paving cannot be carried out. At the same time, due to temperature differences between adjacent road sections, problems such as insufficient compaction and poor flatness at the joints are likely to occur. Splicing multiple machines together has drawbacks such as difficulty in equipment coordination, high construction costs, and complex joint treatment, which seriously affect the construction quality and progress. Therefore, we need a simple widening paving device. Utility Model Content

[0004] The purpose of this invention is to provide a device suitable for widening and paving asphalt pavements, so as to solve the problem of the relatively troublesome widening and paving process mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution, comprising: an outer shell, the outer shell being connected to both sides of a paver via an installation structure; a material conveying pipe connected to the front side of the top of the outer shell, the bottom of the material conveying pipe being connected to the discharge port of the outer shell; a motor fixedly connected to the left side of the top of the outer shell; threaded rods movably connected to both sides of the inner cavity of the outer shell; the output shaft of the motor extending into the inner cavity of the outer shell and fixedly connected to one of the threaded rods; the two threaded rods being connected via a transmission structure; a movable plate threadedly connected between the surfaces of the two threaded rods; the surface of the movable plate being movably connected to the inner wall of the outer shell; a scraper and an screed fixedly connected to the front and rear sides of the bottom of the movable plate, respectively; the bottoms of the scraper and the screed extending to the outer side of the outer shell.

[0006] Preferably, the transmission structure includes a sprocket, the inner cavity of which is fixedly connected to a threaded rod, and two sprockets are movably connected to each other via a chain.

[0007] Preferably, a material distribution plate is fixedly connected to the unloading port of the outer shell, and the surface of the material distribution plate is provided with multiple parallel partitions.

[0008] Preferably, a fixing ring is fixedly connected to the surface of the motor, and the bottom of the fixing ring is fixedly connected to the outer casing.

[0009] Preferably, a placement box is fixedly connected to the left side of the rear side of the outer casing, and a cleaning component is placed inside the placement box.

[0010] Preferably, the mounting structure includes a fixing frame, the surface of which has through holes that match the insertion rod.

[0011] Preferably, the inner cavity of the movable plate is movably connected to four limiting rods, and the top and bottom of the limiting rods are fixedly connected to the inner wall of the outer shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This solution allows operators to connect the outer casing to both sides of the paver when widening is required. The asphalt storage tank inside the paver is then fed through a conveying pipe into the discharge port of the outer casing to widen the paving surface. The operator starts the motor to move the scraper and screed downwards. The scraper removes the top layer of asphalt to create a flat surface, while the screed preheats and compacts the asphalt. If any problems arise with the widening paving device, it can be quickly replaced using the installation structure, making widening the paving process simple and fast. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0022] Example 1:

[0023] Please see Figure 1-5 This utility model provides a technical solution: a device suitable for widening and paving asphalt pavement, comprising: a shell 1, the shell 1 being connected to both sides of a paver via an installation structure; a material conveying pipe 2 being connected to the front side of the top of the shell 1; the bottom of the material conveying pipe 2 being connected to the discharge port of the shell 1; a motor 3 being fixedly connected to the left side of the top of the shell 1; threaded rods 4 being movably connected to both sides of the inner cavity of the shell 1; the output shaft of the motor 3 extending into the inner cavity of the shell 1 and being fixedly connected to one of the threaded rods 4; the two threaded rods 4 being connected to each other via a transmission structure; a movable plate 7 being threadedly connected between the surfaces of the two threaded rods 4; the surface of the movable plate 7 being movably connected to the inner wall of the shell 1; a scraper 8 and an screed 9 being fixedly connected to the front and rear sides of the bottom of the movable plate 7, respectively; the bottoms of the scraper 8 and the screed 9 both extending to the outer side of the shell 1.

[0024] Analysis of the above content: When the paver needs to be widened, the operator connects the outer shell 1 to both sides of the paver through the installation structure. Then, the asphalt storage tank in the paver is fed into the discharge port of the outer shell 1 through the material conveying pipe 2 to widen the ground. The operator starts the motor 3, and the output shaft of the motor 3 drives one of the threaded rods 4 to rotate. The threaded rod 4 then drives the other threaded rod 4 to rotate in the same direction through the transmission structure. During the rotation of the two threaded rods 4, the movable plate 7 moves downward, which indirectly drives the scraper 8 and the screed 9 to move downward. The scraper 8 scrapes the top of the asphalt to make it flat, and then the screed 9 preheats and compacts the asphalt (note: the bottom of the screed 9 is lower than that of the scraper 8). If there is a problem with the widening paving device, it can be quickly replaced through the installation structure, making the widening paving of the paver simple and quick.

[0027] Analysis of the above content: When in use, one of the threaded rods 4 drives the sprocket 5 to rotate, and the sprocket 5 drives the other threaded rod 4 to rotate in the same direction through the chain 6, so that the two threaded rods 4 rotate simultaneously.

[0028] Example 3:

[0029] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: a material distribution plate 10 is fixedly connected to the unloading port of the outer shell 1, and the surface of the material distribution plate 10 is provided with a plurality of parallel partitions.

[0030] Analysis of the above: By setting up the distribution plate 10 to distribute the asphalt into blocks, the block-shaped asphalt can be more evenly distributed on the road surface during paving. Compared with irregularly shaped asphalt, the block-shaped material, under the action of the widened paving device, can be laid on the road surface more orderly, reducing the occurrence of material piles and pits.

The worker connects the snap-fit ​​interface inside the fixing frame 13 to the snap-fit ​​block on the paver, and then inserts the insert rod into the through hole 14 opened on the surface of the fixing frame 13 and the snap-fit ​​block. When it is moved to the corresponding position, the worker fixes the connection between the insert rod and the fixing frame 13 with bolts to complete the installation.

[0040] Example 7:

[0041] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: the inner cavity of the movable plate 7 is movably connected with four limiting rods 15, and the top and bottom of the limiting rods 15 are fixedly connected to the inner wall of the outer shell 1.
