Problems solved by technology

With this structure, the cracks are divided into three grades, and the required inner diameter of the material delivery pipe is manually adjusted, but the depth of the crack is constantly changing. When the delivery pipe needs to be replaced, the workers need to suspend work, which affects the construction efficiency and is not conducive to Crack depth, automatically adjusts the inner diameter of the required delivery pipe

Embodiment 1

[0026] Such as Figure 1-3 As shown, an asphalt pavement filling device includes a vehicle frame 1 on which a hot-melt box 2 and a spray gun are fixed. The spray gun includes a delivery pipe 3 and a nozzle 4. One end of the delivery pipe 3 passes through a feed pump and a hot-melt box. The outlet of 2 is connected, and the other end is connected with the nozzle 4, and the connection assembly 5 with adjustable inner diameter is connected between the delivery pipe 3 and the nozzle 4. The tube 3 and the nozzle 4 communicate with each other through an elastic hose, and an inflatable chamber 6 is formed between the elastic hose and the outer pipe. An air pump 7 is also fixed on the frame 1, and the air pump 7 is connected to the inflatable chamber 6 through an air delivery pipe 8. An air outlet communicating with the inflatable cavity 6 is arranged on the pipe, a control valve 9 is installed at the air outlet, and the air delivery pipe 8 is fixed on the outside of the delivery pipe...

Embodiment 2

[0032] Adopt the using method of the asphalt pavement filling device described in embodiment 1, may further comprise the steps:

[0033] (1) According to the crack depth of the asphalt pavement, the air pump 7 inflates the air chamber 6 to adjust the inner diameter of the elastic hose. When the crack is deep, increase the amount of air in the air chamber 6 to reduce the inner diameter of the elastic hose , by reducing the inner diameter of the elastic hose, increase the discharge pressure of the nozzle 4; when the crack is shallow, reduce the amount of air inflated in the inflation chamber 6, so that the inner diameter of the elastic hose increases;

[0034] (2) The hot melt box 2 heats the potting glue to the required heat, the heated potting glue enters the elastic hose through the delivery pipe 3, and then enters the nozzle 4 through the elastic hose, and is sprayed out through the nozzle 4 to clean the cracks. Pouring.

Abstract

The present invention provides an asphalt pavement joint filling device and method. The asphalt pavement joint filling device includes a vehicle frame, which is provided with a hot-melt box and a spray gun. The spray gun includes a delivery pipe and a nozzle. The outlet of the melting tank is connected, and the other end is connected to the nozzle. A connection assembly with adjustable inner diameter is arranged between the delivery pipe and the nozzle. The connection assembly includes an outer pipe, and a coaxial elastic hose is arranged inside the outer pipe. The elastic hoses communicate with each other, and an inflatable chamber is formed between the elastic hose and the outer tube. An air pump is also arranged on the frame, and the air pump is connected with the inflatable chamber through an air delivery pipe. A control valve is arranged at the air outlet. The invention can adjust the inner diameter of the elastic hose in real time according to the depth of the crack, and adjust the pressure when the nozzle is discharged, so as to meet the needs of filling cracks with different crack depths.

Description

technical field [0001] The invention relates to the technical field of road construction equipment, in particular to an asphalt pavement joint filling device and method. Background technique [0002] After the asphalt pavement is laid, various pavement cracks will appear with use, which will reduce the bearing capacity of the road and reduce the service life of the road. Therefore, it is extremely important to repair the pavement cracks in time. The existing pavement joint filling device mainly fills the cracks through the flow of the potting glue itself, and the joint filling effect is not good for deeper cracks. [0003] CN105887641B discloses a feeding device for a pavement joint filling machine and its use method. The feeding pipes include No. 1 feeding pipe, No. 2 feeding pipe and No. 3 feeding pipe, which are connected in sequence and have different inner diameters. In order to avoid the solidification of the potting glue, a screed is connected to the outlet end of th...
