Embodiment Construction

[0036] Such as Figure 1~3 Among them, the specific structure of the cement pavement crushing vehicle is: one end of the excitation beam 1 is connected to the breaking hammer 3, and the other end of the excitation beam 1 is connected to the excitation source 10;

[0037] The second hinge pin 11 close to the excitation source 10 is hinged with the car body 6 through the tire hinge 9;

[0038] The first hinge pin 2 close to the breaker 3 is hinged to the supporting plate 8 through the connecting rod 4, and the end of the supporting plate 8 away from the connecting rod 4 is hinged to the vehicle body 6;

[0039] The position in the middle of the supporting plate 8 is hinged with one end of the lifting cylinder 7, and the other end of the lifting cylinder 7 is hinged with the car body 6. The preferred solution is as figure 2 Among them, the supporting plate 8 is also provided with a counterweight 5, and the midline of the counterweight 5 is flush with the connecting rod 4. Thr...

Abstract

The invention provides a method for preparing a vibration beam of a road crushing vehicle, comprising the following steps: S1, casting the beam body in a mold cavity; S2, hot forging the beam body; S3, tempering the beam body; S4, finishing the beam body To the preset size, all the positions of the broken lines are rounded; S5, the surface of the beam body is finely ground to ensure that the surface roughness is lower than Ra1.6μm; through the above steps, the excitation beam of the road crushing vehicle is obtained. By adopting the above solutions, the service life of the excitation beam under vibration conditions can be greatly extended. The position of the turning line on the beam body is rounded, which can avoid micro-cracks from being generated as fracture source regions. The surface finishing process is adopted to make the excitation beam have a lower surface roughness. Micro-cracks can be avoided under vibration conditions.

Description

technical field [0001] The invention relates to the field of cement pavement crushing construction equipment, in particular to a method for preparing an excitation beam of a pavement crushing vehicle. Background technique [0002] At present, the equipment used for crushing cement pavement includes single-hammer type, door-knife type and multi-hammer type equipment for crushing. When crushing, it will exert a strong impact on the ground, make noise, and it is difficult to meet the requirements of crushing depth and crushing quality. High energy consumption and low efficiency. [0003] Chinese patent document CN206052519U describes a cement concrete pavement resonance crusher, which crushes the pavement by adopting a resonance mode, with low noise and high efficiency. The cement concrete pavement is crushed by using this vibration excitation method, and the part transmitting the excitation vibration is an excitation beam, and the excitation beam is easy to break under the wo...
