technical field

The invention relates to the technical field of construction and road construction equipment, in particular to an automatic control cutting machine used in construction.

Background technique

With the development of transportation, concrete roads have been vigorously constructed in road construction, but the damage of concrete roads is quite serious, and the road management department needs to repair the roads. Usually, an impact hammer is used to divide the damaged pavement into a small piece of concrete, and then re-pour new concrete. This repair method is laborious, unevenly divided, and inefficient; there is also a cutting machine that sets the cutting depth at the rear of the machine frame. Adjust the screw rod, but the depth is not easy to grasp. The depth is preset each time, and it needs to be reset for different cutting depths next time, which is not convenient. However, the depth of the road is different. Using the preset depth may overcut or cut the concrete continuously, which makes it difficult to separate the concrete from the soil foundation in the later stage, and even requires secondary cutting, which is time-consuming and laborious.

When cutting the road, the operator needs to manually turn the forward disc while paying attention to the cutting situation of the road surface. The personnel itself is a burden; 2) The up and down of the cutting disc is controlled by the electric push rod, but the electric push rod cannot predict the cutting depth, and its essence is still the depth set by humans.

When the present invention is in use,

Move the present invention to the road surface that needs to be cut, first set the cutting depth according to the thickness of the road surface, that is, by adjusting the turntable 5, the board 2 is lowered, and then the driving box 11 is driven to move down, so that the cutting blade 18 is lowered. Move to the set depth, and then cut the road surface. During the cutting process, the force of the cutting piece 18 can be sensed by the torque sensor 17 and transmitted to the control system. Due to the density and hardness of the concrete road surface and soil foundation, etc. The reason is that the stress of the cutting piece 18 when it cuts the concrete pavement and soil foundation also changes, and the torque detected by the torque sensor 17 also changes. The system transmits the signal to the hydraulic cylinder 28 according to the signal change. The cylinder 28 changes the extension length, thereby pushing the wedge block 8 to move horizontally in the "T" groove 7. Since the drive box 11 is fixed by the slide rail 13 in the frame 1, it can only be used in the vertical direction in the frame 1. When the hydraulic cylinder 28 is extended, the wedge-shaped block 8 pushes the lug 10, so that the drive box 11 moves downward, and vice versa, the depth of the cutting blade 18 also changes accordingly. When cutting, the concrete road surface can just be cut The cutting is complete, and the soil foundation will not be cut too much, causing the cutting sheet 18 to be bonded and broken.

Since the angle range of the first wedge angle 31 is between 8-15°, the wedge block 8 and the lug 10 can realize self-locking, the height change of the drive box 11 is operated by the wedge block 8, and the drive box 10 itself cannot make the wedge The block 8 is displaced, so before the torque of the output shaft 26 does not change, the height of the drive box 11 will not change, thereby ensuring the stability of cutting. The surface finish of the wedge block 8 and the lug 10 is required to be relatively high, so as to ensure that the wedge block 8 and the lug 10 will not be stuck due to excessive friction when sliding.

The screw 3 and the fixed block 4 adopt threads with self-locking angles. Only by turning the screw can the height of the board 2 change, and the force of the board 2 cannot make the screw 3 rotate, so adjust the height of the board 2 Afterwards, it can be fixed, and the depth of the cutting blade 18 is fine-tuned by the action of the hydraulic cylinder 28, without making a large change in the height.

The cutting piece 18 is connected with the output shaft 26 through the elastic key 29, which can play a certain buffering effect when the cutting knife does not turn due to foreign matter cut during cutting, so as to avoid the direct damage of the cutting piece 18.

Compared with the traditional cutting machine, the present invention has the following beneficial effects: 1) It adopts hydraulic power, which is more moderate and can also save energy; 2) A torque sensor is installed on the output shaft, and the force of the cutting piece is fed back to the control system in real time According to the feedback, the depth of the cutting piece can be fine-tuned at any time, so that the cutting piece can cut the concrete pavement completely, neither cutting the concrete nor cutting too much soil foundation; 3) The elastic key is used to connect the original The rigid connection is changed to the rigid connection with buffer, which can not only play the role of traditional key connection, but also play the role of buffer, which has a certain protection for the cutting piece.

The invention has a simple and reasonable structure, can control the up and down movement of the cutting piece while cutting, ensures that the cut road can be completely separated from the soil foundation, and avoids secondary construction.
