Description

Technical Field

[0001] The utility model belongs to the technical field of road engineering equipment, and in particular relates to a synchronous filling device for an emulsified asphalt synchronous spreading paver. Background Art

[0002] Around 2002, my country began to introduce ultra-thin wearing layer construction technology that uses simultaneous spreading of emulsified asphalt tack coat. This technology uses a special paver to combine traditional emulsified asphalt tack coat spreading with hot mix paving, greatly reducing the risk of damage and contamination of the emulsified asphalt tack coat during pavement paving.

[0003] At present, all construction units add emulsified asphalt to the ultra-thin wear layer surface by stopping the machine to add emulsified asphalt. The emulsified asphalt spreading amount is 0.8kg / ㎡. Each tank of emulsified asphalt can be paved for about 430m. Then it takes 20min / time to add emulsified asphalt. There are many pauses in the middle and the total time for filling is relatively long, which prolongs the road closure time, increases safety risks, and affects quality indicators such as pavement flatness, paving, and initial pressure temperature. Utility Model Content

[0004] In view of the problem that the existing synchronous ultra-thin wearing layer overlay is shut down for filling emulsified asphalt, which affects the construction safety and quality, the utility model provides a synchronous filling device for emulsified asphalt of a synchronous spreading paver, which can achieve the purpose of synchronous ultra-thin wearing layer overlay without stopping the machine to fill emulsified asphalt, thereby reducing construction safety risks and improving construction quality.

[0005] The utility model provides the following technical solutions:

[0006] The utility model provides a synchronous asphalt filling device for a synchronous spreading paver, comprising:

[0007] The vehicle-mounted emulsified asphalt storage tank is installed on the emulsified asphalt storage vehicle; the booster pump is installed on the vehicle-mounted emulsified asphalt storage tank; the paver emulsified asphalt storage tank is installed on the synchronous spreading paver; the delivery hose is wound on the pipe winch, and the winch is installed on the rear side of the emulsified asphalt storage vehicle through a fixed bracket; both ends of the delivery hose are respectively connected to the booster pump and the paver emulsified asphalt storage tank.

[0008] The emulsified asphalt in the storage tank is pressurized by a booster pump and then poured into the emulsified asphalt storage tank of the paver through a delivery hose.

[0009] The extension and shortening of the delivery hose can be adjusted by turning the pipe capstan.

[0010] The vehicle-mounted emulsified asphalt storage tank has an emulsified asphalt storage capacity of 10t.

[0011] The vehicle-mounted emulsified asphalt booster pump is an electrically driven sewage pump, which is provided with a filtering device and has a conveying capacity of 4 to 6 t / h.

[0012] The emulsified asphalt storage tank of the paver has an emulsified asphalt storage capacity of 2 tons.

[0013] The conveying hose has a diameter of 50 mm, a length of 5-30 m, and a theoretical displacement of 50-100 L / min.

[0014] Compared with the traditional emulsified asphalt filling method, the utility model has the following beneficial technical effects:

[0015] When traditionally filling emulsified asphalt, due to the lack of an emulsified asphalt conveying device with length adjustment function, it is difficult to meet the filling requirements between the emulsified asphalt storage truck and the synchronous spreading paver at different parking positions (when paving one lane, the emulsified asphalt storage truck needs to stop at the second lane; when paving two lanes, the emulsified asphalt storage truck needs to stop at one lane; when paving two lanes at the same time, the emulsified asphalt storage truck needs to be in front of the material transport truck in front of the paver); and two lanes must be occupied during filling.

[0016] The utility model has a simple structure and can realize non-stop filling of emulsified asphalt of the synchronous spreading paver while keeping the synchronous spreading paver and the emulsified asphalt storage vehicle moving forward in parallel, thereby reducing the road closure time caused by stopping for filling emulsified asphalt and avoiding problems such as hidden dangers of road quality caused by stopping.

[0019] like Figure 1 As shown, it is a synchronous spreading and filling device for emulsified asphalt of a paving machine, wherein a vehicle-mounted emulsified asphalt booster pump 2 is installed on a vehicle-mounted emulsified asphalt storage tank 1; a delivery hose 5 is used to connect the vehicle-mounted emulsified asphalt booster pump 2 and the paving machine emulsified asphalt storage tank 6; the delivery hose 5 realizes the extension and contraction of the device through a pipeline winch 4; the pipeline winch 4 is fixed to the emulsified asphalt storage vehicle through a fixing frame 3. During the paving process, the device pressurizes the emulsified asphalt in the vehicle-mounted emulsified asphalt storage tank 1 through the vehicle-mounted emulsified asphalt booster pump 2, and the emulsified asphalt is filled from the vehicle-mounted emulsified asphalt storage tank 1 (port A) to the paving machine emulsified asphalt storage tank 6 (port B) through the delivery hose 5.

[0020] Specific working principle:

[0021] Install the device, adjust the delivery hose 5 to a suitable length through the pipe winch 4 according to the distance between the emulsified asphalt storage vehicle and the synchronous spreading paver, turn on the vehicle-mounted emulsified asphalt booster pump 2, and obtain a suitable emulsified asphalt filling speed by adjusting the working pressure of the vehicle-mounted emulsified asphalt booster pump 2. The emulsified asphalt flows from the vehicle-mounted emulsified asphalt storage tank 1 through the A port of the emulsified asphalt booster pump 2, flows through the delivery hose 5, and enters the tank through the B port of the emulsified asphalt storage tank 6 of the paver.

[0022] The emulsified asphalt storage vehicle is located in front of or on either side of the synchronous spreading paver. The synchronous spreading paver moves synchronously in the direction of the emulsified asphalt storage vehicle and moves to the side or rear of the emulsified asphalt storage vehicle. During the paving process, the paving direction and paving speed of the synchronous spreading paver are kept consistent with the direction and speed of the emulsified asphalt storage vehicle to achieve synchronous filling of the emulsified asphalt.
