Problems solved by technology

At present, the commonly used tools for breaking concrete pavement include jackhammers, hydraulic breaking hammers, and cement pavement crushers. Noise, even accidents caused by splashing gravel and hurting people, so it is not suitable for road construction in densely populated cities, especially near hospitals, schools and residential buildings. The noise generated by wind pick construction will greatly affect people's lives; It takes a long time to use pneumatic picks, hydraulic breakers and cement pavement breakers to break the road surface. For some road sections, such as airport runways and road sections with heavy traffic volume, road closure construction is required, which seriously affects normal traffic, causing vehicle congestion or flight delays. People's normal travel and work; and now in order to improve the mechanical properties of concrete roads, steel mesh is often laid in cement concrete. Commonly used concrete breaking tools can only break concrete stones, it is difficult to cut off steel bars, and steel bars need to be cleaned separately. Therefore, the construction efficiency is low. The use of pneumatic picks, hydraulic breakers and cement pavement crushers to break the pavement will affect the surrounding pavement, and the vibration will damage the pavement structure, causing the concrete to peel off from the steel bars in the concrete, reducing the strength of the pavement and reducing the normal service life of the concrete pavement.

Embodiment 1

[0036] refer to Figure 1-5 , this embodiment discloses an automatic full-scale update equipment for assembled concrete pavement, including: a support frame 1; The bottom surface is fixedly connected to the top surface of the crawler wheels 2 of the crawler chassis respectively, and the bottom of the support frame 1 is provided with a lifting device, the lifting device is arranged in a rectangular structure, and the four sides of the lifting device are provided with cutting devices;

[0037] The lifting device comprises a lifting plate 3, the bottom surface of the lifting plate 3 is provided with several towing hooks 4, the towing hooks 4 are used to lift and cut the finished paving panel, and the top surface of the lifting plate 3 is provided with a lateral displacement mechanism for To drive the lifting plate 3 to carry out lateral displacement; the two opposite sides of the support frame 1 are fixedly connected with bar sliders 5, and the two sides of the top surface of the...

Embodiment 2

[0066] refer to Figure 6-7 In order to achieve a more free adjustment of the position of the towing hook 4 on the bottom surface of the lifting plate 3, the towing hook 4 includes a sliding column 40, the top surface of the sliding column 40 is fixed with a disc 41, and the bottom surface of the sliding column 40 is fixed with a hinge seat 42, the hinged seat 42 is hinged with a hook 45, and the bottom surface of the lifting plate 3 is provided with a number of horizontal T-shaped slots 43 and vertical T-shaped slots 44, and the horizontal T-shaped slots 43 and vertical T-shaped slots 44 are arranged alternately. And the sliding column 40 is slidingly connected with the inner wall of the horizontal T-shaped groove 43 and the vertical T-shaped groove 44. Such setting increases the range of motion of the tow hook 4. During the cutting process, the rivet fixation in advance has limitations, and then It is easy to cause errors when docking. This embodiment can increase the range ...

Embodiment 3

[0069] Due to the volume factor of the track wheel 2, it is difficult to accurately locate the pavement to be replaced through the guidance of the track wheel 2. Therefore, in this embodiment, infrared transmitters are installed at the edges of the pavement to be replaced to emit infrared rays, and installed inside the track wheel 2. Infrared receiver, the device automatically moves to the top of the pavement to be replaced through infrared positioning, and cuts through the precise positioning of the cutting position through the lateral displacement mechanism and cutting device. The infrared emitter and the infrared receiver arranged are all prior art.

[0070] Since the internal structure of the pavement to be replaced is relatively complex, the interior is not only a concrete structure, but also equipped with steel mesh, so when cutting, the cutting device cannot cut at the same cutting speed, and different cutting torques are required for different cutting objects. cutting,...

The automatic full-scale updating equipment comprises a supporting frame; a crawler chassis is arranged at the bottom of the supporting frame, two limiting devices are arranged on the two sides of the supporting frame respectively, the bottom faces of the limiting devices are fixedly connected with the top faces of crawler wheels of the crawler chassis respectively, a lifting device is arranged at the bottom of the supporting frame, and the lifting device is of a rectangular structure. Cutting devices are arranged on four side surfaces of the lifting device; each cutting device comprises a direction adjusting mechanism, an extending mechanism and a cutting mechanism; the direction adjusting mechanism is in transmission connection with the side face of the lifting plate, the extending mechanism is arranged on the side face of the direction adjusting mechanism and used for driving the cutting mechanism to extend in the transverse direction, and the cutting mechanism is arranged at the bottom of the extending mechanism.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to an automatic full-scale update equipment for assembled concrete paving panels. Background technique [0002] Concrete pavement reconstruction is a cumbersome construction process that requires the pavement to be crushed and then paved. At present, the commonly used tools for breaking concrete pavement include jackhammers, hydraulic breaking hammers, and cement pavement crushers. Noise, even accidents caused by splashing gravel and hurting people, so it is not suitable for road construction in densely populated cities, especially near hospitals, schools and residential buildings. The noise generated by wind pick construction will greatly affect people's lives; It takes a long time to use pneumatic picks, hydraulic breakers and cement pavement breakers to break the road surface. For some road sections, such as airport runways and road sections with heavy traffic volume, road ...
