Device with function of monitoring elevation angle change of paver screed

Abstract

The utility model relates to a device with a function of monitoring the elevation angle change of a paver screed. The device comprises a laser emitting mechanism, a laser passing mechanism and a laser receiving mechanism, when an elevation angle is at an angle of normal paving, three laser rays emitted by an upper emitter, a middle emitter and a lower emitter of the laser emitting mechanism can be received by an upper receiver, a middle receiver and a lower receiver through gaps respectively; when the elevation angle is increased, the laser rays emitted by the lower emitter are shielded by the lower shielding plate, the lower receiver cannot receive the rays and transmits a signal to the controller, and the controller controls the leveling oil cylinder to extend and restore to the elevation angle when the leveling oil cylinder is balanced; when the elevation angle is reduced, the laser rays emitted by the upper emitter are shielded by the upper shielding plate, the upper receiver cannot receive the rays, a signal is transmitted to the controller, and the controller controls the leveling oil cylinder to shorten and restore to the elevation angle when the leveling oil cylinder is balanced; the adjusting device is small in size, convenient to transfer and install, capable of closely monitoring elevation angle changes, capable of ensuring paving quality and easy and convenient to debug.

Description

technical field [0001] The invention relates to a device with the function of 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] like 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 rema...

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
