Problems solved by technology

This causes the equipment to be bulky, heavy and complex in structure.
With this structure, when changing the direction of the specimen and loading and unloading the specimen, it is necessary to manipulate the sprocket transmission mechanism to control the weight to move to the beginning of the beam, and then manually lift the rolling wheel of the beam to unload the specimen or The direction of the test piece is changed, the operation is cumbersome and labor-intensive
During the rolling process, the mixture is uneven, causing the scale beam and the weight to vibrate, causing the rolling pressure to fluctuate, and bringing many random unstable factors to the test process

Embodiment Construction

[0022] The invention provides a mobile asphalt mixture on-site wheel mill forming machine. The structure of the mobile asphalt mixture on-site wheel milling machine is as follows: figure 1 shown.

[0023] The forming machine includes a car body, a speed reduction mechanism, a trial mold frame, a hydraulic loading system and a wheel mill support assembly. The car body includes a vehicle frame 1, wheels and handlebars. Below the frame, it is easy to move the frame. The vehicle frame is a box body structure, and the speed reduction mechanism is installed in the vehicle frame box body.

[0024] Such as figure 2 As shown, the reduction mechanism includes a first motor (2), a reducer (3), a small sprocket (41), a large sprocket (42), a transmission chain 43, and a turntable 5. The reducer is a cycloidal pin wheel planetary reducer, which applies the principle of planetary transmission, adopts cycloidal pin-tooth meshing, has a large reduction ratio, and the meshing parts adopt ...

Abstract

The invention provides a movable asphalt mixture forming machine which comprises a vehicle body, a speed reduction mechanism, a test die frame for arranging a test die, a hydraulic loading system and a wheel milling bracket assembly. The movable asphalt mixture forming machine is characterized in that the vehicle body is provided with wheels; the speed reduction mechanism is arranged in the vehicle body; the test die frame is movably arranged on the upper surface of the vehicle body; and the hydraulic loading system is used for driving a milling wheel in the wheel milling bracket assembly to apply a load to the test die in the test die frame.

Description

technical field [0001] The invention relates to a wheel milling machine, in particular to a mobile asphalt mixture wheel milling machine. Background technique [0002] According to the requirements, when conducting the asphalt mixture rutting test, the specimen must be formed by the wheel rolling method. [0003] At present, the asphalt mixture wheel milling machines used at home and abroad are bulky and heavy, and are only suitable for laboratory use. Therefore, the preparation of the test piece has to take the mixed material from the construction site back to the laboratory, and then reheat the cooled mixture. In this way, the asphalt is aged due to reheating, which seriously affects the accuracy of the test results. [0004] Currently used asphalt wheel milling machines are limited by their structural principles. First of all, the moving speed of the test piece in the rolling process is controlled by gear transmission and sprocket mechanism through several stages of de...
