Description

Technical Field

[0001] The utility model relates to the field of roadbed paving, in particular to a roadbed paving device for highway expansion. Background Art

[0002] Roadbed expansion refers to the expansion or modification of the existing roadbed to accommodate increased traffic or improve road infrastructure. First, planning and design work is required to determine the specific scope of the roadbed expansion and the modification plan, including the width, slope, drainage system, etc. of the roadbed. Before the actual expansion, the surrounding land needs to be prepared, which may include clearing vegetation, excavating or filling soil, etc. According to the design plan, widening the existing roadbed usually involves excavation and filling.

[0003] The Chinese patent with publication number: CN220364831U provides a roadbed paving device, which relates to the technical field of roadbed construction. The roadbed paving device includes a device body, and a pull rod, a control box and a signal transmitter are arranged at the upper end of the device body; a roadbed paving device, through the setting of a tamping component, is started through a mobile phone app end and a first cylinder, so as to drive a tamping plate to tamp the road surface at the bottom of the device body, and reciprocate to facilitate the subsequent discharge of concrete mortar; through the setting of a spreading component, the spreading nails reciprocate along the concrete mortar, so as to spread the concrete mortar, which is convenient for the subsequent paving of the scraper; through the setting of the leveling component, after the concrete mortar is spread by the spreading nails, the height of the concrete mortar is identified by an infrared sensor, and then the scraper is driven to move downward along the second moving hole by the third cylinder, so as to freely control the height of the scraper, so that the concrete mortar is scraped flat by the scraper, and the paving efficiency is improved.

[0004] However, there are the following shortcomings in the above-mentioned method: during the paving operation, although the concrete mortar can initially cover the dust on the road, a large amount of dust will still be raised as the compaction operation moves. After the dust is inhaled into the respiratory tract by the construction workers, it may cause respiratory diseases such as tuberculosis. Therefore, a highway expansion roadbed paving device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a roadbed paving device for highway expansion, and the utility model is implemented through the following technical scheme: it includes a frame base, a groove is opened in the middle position of the bottom of the frame base, a water tank is installed at the right position of the middle of the top of the frame base, a water pipe is connected through the middle position of the right side wall of the water tank, a shunt pipe is installed in the middle position of the right side wall of the water pipe, a plurality of output ports are opened in the middle position of the right side wall of the shunt pipe, and the plurality of output ports are connected to atomizing nozzles, and the plurality of atomizing nozzles are distributed in an array.

[0006] Furthermore, the water pipe transports the water in the water tank to the diversion pipe and sprays it through a number of atomizing nozzles, thereby playing a role in dust reduction and preventing the large amount of dust generated during the laying operation from being inhaled into the breathing ducts of the construction workers, thereby affecting the health of the construction workers.

[0007] Furthermore, a storage tank is installed in the middle of the top of the frame base and close to the left side of the water tank. A feeding port is provided on the top of the storage tank, and a unloading mechanism is installed in the middle of the bottom of the storage tank. The output end of the unloading mechanism passes through the middle of the bottom of the groove on the left side, and the concrete mortar in the storage tank is unloaded through the unloading mechanism.

[0008] Furthermore, the output end of the first cylinder drives the U-shaped transmission frame to translate downward, thereby causing the transmission block to translate downward, and the concrete mortar is evenly spread through a plurality of groups of spreading rods.

[0009] Furthermore, by means of springs installed in several groups of positioning sleeves, a cushioning effect is provided to the spreading rods during the spreading operation, thereby preventing the spreading rods from being subjected to large forces, which may cause damage or distortion to individual spreading rods, and improving the service life of the equipment.

[0010] Furthermore, the output end of the second cylinder acts on the transmission plate, and the transmission plate acts on the two mounting plates to drive the compacting roller to move downward to compact the concrete mortar.

[0011] Furthermore, the compaction roller is driven to rotate by the first motor, thereby improving the compaction efficiency.

[0012] Furthermore, the construction workers pushed the vehicle forward using two connecting handles.

[0013] Furthermore, the control box is electrically connected to the external controller, the first motor, the first cylinder, the second cylinder, and the water pipe respectively.

[0016] 2. In the utility model: the atomizing nozzle can atomize water or other liquids into tiny water droplets. These tiny water droplets can combine with dust particles suspended in the air, so as to adsorb the dust particles to the surface of the water droplets to achieve the effect of dust reduction. Compared with the traditional spray system, the atomizing nozzle uses less water and can effectively save water resources.

[0017] 3. In the utility model, a plurality of sets of positioning sleeves are used to install springs, so as to provide a cushioning effect for the spreading rods during the spreading operation, thereby preventing the spreading rods from being subjected to large forces, which may cause damage and distortion to individual spreading rods, and improving the service life of the equipment.
