[0002] Raking the heated asphalt pavement is one of the main functions of the asphalt pavement hot-in-place regeneration equipment. The existing asphalt pavement hot-in-place regeneration equipment road raking devices use hydraulic cylinders to control the rake height. Due to the incompressibility of hydraulic oil, Once the piston rod of the hydraulic cylinder extends out to a certain length, the h

Abstract

The invention discloses a spiking-up device used for an asphalt pavement, comprising a basic frame, a swaying frame, a cylinder, a spring, an assistant spiking-up swaying-arm, an assistant scarifying device and a main spiking-up device. The body of the cylinder is articulated to the back end of the basic frame, and the front end of the swaying frame is articulated with the front end of the basic frame, and the middle part of the swaying frame is articulated with the piston rod of the cylinder to form a triangle support; the back part of the swaying frame is raised upwards; the front end of the assistant spiking-up swaying-arm is articulated with the middle part of the swaying frame, and the spring is supported between the upper part of back end of the assistant spiking-up swaying-arm and the back part of the swaying frame; the assistant spiking-up device is arranged on a lower part of the back end of the assistant spiking-up swaying-arm; the main spiking-up device is arranged in the middle of the swaying frame. The spiking-up device adopts the whole cylinder for pressurizing and back-row assistant spiking-up device spring for pressurizing so as to make use of the compressibility of compressed air and automatic flexibility of spring to guarantee the tooth of spiking-up device to constantly contact pavement spiked-up and to avoid that the concave pavement can not be spiked-up and the projecting parts on pavement block the moving of spiking-up device or cause damage to the device.

Description

technical field [0001] The invention relates to an asphalt pavement raking device, which belongs to the technical field of in-situ heat regeneration construction equipment for asphalt pavement. Background technique [0002] Raking the heated asphalt pavement is one of the main functions of the asphalt pavement hot-in-place regeneration equipment. The existing asphalt pavement hot-in-place regeneration equipment road raking devices use hydraulic cylinders to control the rake height. Due to the incompressibility of hydraulic oil, Once the piston rod of the hydraulic cylinder extends out to a certain length, the height of the asphalt pavement loosening rake is determined. In this way, the height of the loosening rake cannot adapt to changes in the height of the road surface and always keep in contact with the road surface. When there are pits on the road surface, it cannot be raked. When the road surface is raised, mechanical damage is caused due to the lack of cushioning and a...
