Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
The existing precast slab paving and paving technology basically adopts two modes of template limiting infusion or paving trolley operation, the template limiting infusion very depends on the manual operation quality, and the intelligent degree of the paving trolley is not high enough, so that the paving effect is not ideal. If the precast slab is laid before the mud distribution and the density are not uniform in the bottom layer connection, the slab laying quality of the precast slab is poor, the slab stress is not uniform, the defects of cracks, road surface staggering and the like are extremely easy to generate, the precast slab is finally broken, and the use and the construction progress of the adjacent road are seriously influenced. The cantilever crane or the gantry crane is basically used for lifting, but the cantilever crane also depends on manual operation precision, and the gantry crane cannot adapt to multi-degree-of-freedom paving equipment and is not beneficial to efficiency improvement.
Moreover, the running freedom degree of the whole process equipment cannot be controlled, so that the angle and the running direction are not adjustable, and the laying process and the laying effect are affected. And the existing paving process and the paving process are split into two construction processes which are not related to each other, and the slurry is exposed in the air for a long time due to the fact that the paving process is slow and the paving process is fast, so that self-solidification is carried out, and the connection tightness is seriously affected.
The embodiment provides a split type intelligent paving board paving method, which not only solves the problems, but also can realize intelligent control, improves the construction efficiency, namely adopts multi-means to self-coordinate the hole value paving quality and the board paving quality, and improves the board type quality of the precast boards.
As shown in fig. 1-10, the present embodiment provides a method of paving a board, comprising:

That is, the method of paving a board uses a mortar spreader 1 for spreading mortar 3 and a board spreader 2 for spreading board on the surface of the spread mortar 3. The mortar paver 1 and the plate paving machine 2 jointly form full-flow paving equipment, a sensing mechanism can be arranged on the mortar paver 1 and the plate paving machine 2 in a mode of how the full-flow paving equipment is intelligently operated, a complete machine monitoring and regulating system for the full-flow paving equipment is formed, real-time states of the mortar paver 1 and the plate paving machine 2 are sensed, association is achieved, and normal operation of a regulation and control guarantee process is facilitated.
When concrete implementation, can set up first binocular camera 15 in the rear side department of mortar paver 1 towards the board paving machine, this first binocular camera 15 is used for realizing the coordinated construction of mortar paver and board paving machine to feed back the unit through first binocular camera 15 and follow-up state to control the regulation through main control system, so as to reach the effect of intelligent continuation construction, at unmanned time interval promptly, carry out the construction of spreading by oneself, reach intelligent automatic control's purpose. Therefore, compared with the existing paving process, the paving method provided by the disclosure shows a brand-new full-flow integrated split intelligent paving and paving construction process, adopts a two-machine ordered stepping construction scheme, uniformly configures the two independent construction processes in the past, realizes coordinated construction, ensures paving quality and paving quality in the paving process, improves working efficiency, and saves intermediate time.
Specifically, as shown in fig. 2, the mortar spreader 1 includes a first traveling frame 11, at least one traveling leg 5 is installed on both sides of the first traveling frame 11 in a preset direction, and the mortar spreader 1 is driven to move by the traveling leg 5. In the embodiment, two travelling support legs 5 are respectively arranged on two side edges of the first travelling frame 11 so as to ensure the stability in the moving process. Of course, the number of travel legs 5 may be selectively adjusted in other embodiments. The separator 12 is mounted on the first travelling frame 11, and the outlet of the separator 12 faces the ground, and the width extending direction of the separator 12 is perpendicular to the preset direction, so that the outlet extending direction of the separator 12 is also perpendicular to the preset direction, so as to ensure that the laying degree at each position along the width is basically consistent in the travelling process.
As shown in fig. 3, the mortar spreader 1 further includes a trowelling mechanism 13, where the trowelling mechanism 13 is disposed at the bottom of the first travelling frame 11 and is located at the rear of the spreader 12 along the preset direction, and the trowelling mechanism 13 is connected to the first travelling frame 11 through a first full-freedom-degree adjusting device 14. Thus, the step of spreading mortar to the ground by the material distributor further comprises:

Due to the arrangement of the mortar conveying mechanism 6, the mortar spreader 1 is slowly moved in the preset direction, and the material distributor 12 of the mortar spreader 1 needs to feed the material distributor 12 and then spread the mortar 3 to the ground in the step of spreading the mortar 3 to the ground during the movement.
To achieve an intelligent control of the process of mortar spreading, the mortar spreader 1 further comprises a flow monitoring mechanism (not shown in the figures), the sensor of which is arranged at the outlet of the spreader 12. The flow monitoring mechanism combines the control system of the full-flow paving equipment to adaptively adjust the opening and closing degree of the discharge port through the monitored signals, control the discharge amount and promote the uniformity degree of cloth.

The step of feeding the separator 12 includes monitoring the mortar 3 at each position at the outlet, and then taking into consideration whether the position of the discharge end at the feed port needs to be adjusted according to the flow rate of the mortar 3 at the outlet, due to the arrangement of the flow rate monitoring mechanism, the sensing mechanism, and the like.
