Device for monitoring elevation angle change of paver screed

Abstract

The utility model discloses a device for monitoring elevation angle change of a paver screed. The device comprises a laser emitting mechanism, a laser reflecting mechanism and a laser receiving mechanism; the laser emitting mechanism comprises laser transmitters and a mounting bracket which are respectively arranged on the sides where large arms on two sides of the paver are located, and the laser transmitters are mounted at the upper end of the mounting bracket, and are higher than the large arms on the sides where the laser transmitters are located; the laser reflecting mechanism comprises reflecting mirror surfaces which are respectively arranged on the large arm, the reflecting mirror surfaces are rotationally connected with a mounting support fixed on the large arm, and light rays emitted by the laser emitter on each side fall into a rotating adjusting range of the reflecting mirror surface on the side where the light rays are located; the laser receiving mechanism comprises a receiver mounting table and a laser receiver, and the upper end of the mounting table is connected with the laser receiver; and the laser receiver comprises a rear-end receiver, a middle receiver and a front-end receiver, and the reflection range of the reflection mirror surface is not smaller than the laser receiver area. The device is convenient to transfer and install; elevation angle changes are closely monitored, and the paving quality is ensured; and disassembly and assembly are convenient, and debugging is simple.

Description

technical field [0001] The invention relates to a device for monitoring changes in the elevation angle of a paver screed. Background technique [0002] The paver is one of the key equipment for building various grades of roads and municipal roads, as well as the base and surface layers of squares, airports, parking lots, dams and ditches. The asphalt concrete, stabilized soil and other mixed paving materials conveyed by the machine are leveled, shaped and pre-compacted to provide good working conditions for the subsequent further compaction of the road roller. [0003] Such as figure 1 As shown, the screed device of the paver needs to maintain an elevation angle α between the screed plate and the material during the paving operation. It is also the existence of this elevation angle that the resultant moment of the moment system formed by the acting force on the ironing device in a stable working state is zero. When the height of the front traction point remains unchanged ...

Problems solved by technology

The measurement devices used in the above two measurement methods are all rigidly installed on the boom. The device is bulky and inconvenient to install in transition; The installation requirements are high. For long distances, a bracket should be placed under the wire rope at intervals to ensure the level of the wire rope. The probe calculation requires high flatness of the base. If the base is not smooth, it will directly affect the paving quality; disassembly is inconvenient , it takes a long time to debug and there are many processes
