Description

Technical Field

[0001] The present invention relates to the technical field of small-grain stone paving construction, and more particularly to a small-grain stone paving construction device and a construction method thereof. Background Art

[0002] A small stone paving machine is a device used for paving roads, sidewalks, and other areas. It typically consists of the following components: a paving machine, which lays the small stone blocks on the ground. The paving machine typically features adjustable height and width to accommodate different paving requirements; a vibrator, which vibrates and compacts the small stone blocks to ensure they are firmly fixed to the ground; a conveyor system, which transports the small stone blocks from the storage area to the paving machine. This conveyor system typically includes a conveyor belt or other similar device; and a control system, which controls the operation of the paving machine and vibrator to ensure smooth paving operations.

[0003] The function of the vibrator is to fix and compact the small stones in position on the roadbed. Since the pressure plate at the bottom of the vibrator is in place as a whole, the force on each small stone is affected by the surrounding small stones, resulting in non-compaction and insufficient fixing effect. In actual construction, the laying of cement or soil in the roadbed is not necessarily completely uniform, which leads to different degrees of settlement of small stones on the road surface easily after installation due to long-term use. It not only affects the use of the road, but also greatly reduces the aesthetics. The subsequent maintenance method is cumbersome and costly. Summary of the Invention

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0045] Example 1:

[0046] See also Figure 1-6A small stone paving construction device includes: a vibrating machine frame 1, the vibrating machine frame 1 is used to install other parts of the vibrating machine to form a main body; a vibrating mechanism 2, the vibrating mechanism 2 is used to generate a vibration amplitude to give the vibrating machine a vibration effect; a small stone pressing plate 3, the small stone pressing plate 3 is installed below the vibrating mechanism 2 to receive the vibration of the vibrating mechanism 2 and transmit it to the small stone, wherein the small stone pressing plate 3 includes a mounting plate 31, and the bottom of the mounting plate 31 is equipped with evenly distributed vibration plates 32 for contacting and pressing the small stone; a control system 4, the control system 4 is used to control the vibration frequency and vibration amplitude of the vibrating mechanism 2, and at the same time analyze the paving status of the small stone;

[0047] The bottom of the mounting plate 31 is integrally formed with evenly distributed air pipes 33. The inner side of the air pipe 33 is connected to a connecting rod 34 via a piston. The bottom end of the connecting rod 34 is detachably connected to the vibration plate 32 via a bolt.

[0048] The pressure plate at the bottom of the existing vibrating machine is divided into small pieces corresponding to small blocks or small areas of small stones, so as to achieve the effect of vibrating and compacting the small stones separately and improving the fixing effect. The vibration amplitude and vibration frequency are adjusted by the control system 4, and the piston of the connecting rod 34 is connected through the air pipe 33, so that a buffer space is provided between the vibrating plate 32 and the mounting plate 31, which plays a protective role for the vibrating machine and the paved small stones and reduces the problem of small stones being easily broken.

[0049] A through pipe 35 is connected between two adjacent air pipes 33. A micro electromagnetic valve 36 is fixedly installed on each through pipe 35. An inflation pipe 37 is fixedly installed on the air pipe 33 on the left front side and connected to the inside thereof. A pressure sensor 38 is fixedly installed inside the inflation pipe 37.

[0050] By connecting each air pipe 33 through the through pipe 35, when the air pressure is added or adjusted in the air pipe 33 through the air filling pipe 37, the internal air pressure of each air pipe 33 can be kept the same, thereby ensuring that each small stone is subjected to uniform vibration and pressure effects during the paving process of the small stones. During the vibration compaction of the small stones, the control system 4 controls the micro electromagnetic valve 36 to close the through pipe 35 and isolate each air pipe 33, thereby ensuring the accurate detection effect of the pressure sensor 38 in each air pipe 33.

[0051] The small stone pressing plate 3 also includes a connecting rod 39, which is used to connect and limit two adjacent vibration plates 32;

[0052] The front and back of the mounting plate 31 are fixed with expansion vibration fixing plates 5 by bolts. The expansion vibration fixing plates 5 have the same structure as the small stone pressing plate 3.

[0053] Among them, according to the size and specifications of the top area of ​​the small stones, the connecting rod 39 connects the two adjacent vibration plates 32, so as to match the area size of the small stones, and play the role of synchronizing the two adjacent vibration plates 32, so that the pressure on the top of the small stones is not concentrated, the uniform contact area is increased, and the small stones are protected. At the same time, according to the width and area of ​​the paved road surface, an expansion vibration fixing plate 5 can be installed on the front and back of the mounting plate 31, so that the expansion vibration fixing plate 5 can play the same purpose of vibrating and compacting the small stones as the small stone pressure plate 3, thereby improving construction efficiency and meeting the small stone paving needs.

[0054] like Figure 5 As shown, the slots on the two adjacent vibration plates 32 are connected by a connecting rod 39, which is used to limit the linkage of the upper and lower vibrations of the adjacent vibration plates 32. According to the above embodiment, two vibration plates 32 can be connected to form a whole, or four vibration plates 32 can be connected to form a whole, which can be adjusted according to the actual area of ​​the small stones.

[0055] Example 2:

[0056] This embodiment is based on the embodiment 1. Figure 1-6 The control system 4 includes a data processing module 41, a PLC controller 42, an alarm module 43, a recording module 44, a chart generation module 45 and a picture display module 46; the data processing module 41 is used to receive the detection data of the pressure sensor 38, analyze the force and paving effect of the small stones under each vibration plate 32, and upload the results to the recording module 44 for recording; the PLC controller 42 is used to control the operation of the vibration mechanism 2 and the micro solenoid valve 36; the alarm module 43 is used to alarm when the data processing module 41 analyzes that the difference in the vibration compaction force of individual small stones exceeds the threshold, so as to remind the construction personnel to make adjustments; the recording module 44 is used to record the movement of the vibrator and the analysis results of the data processing module 41 in real time; the chart generation module 45 is used to generate a gridded picture based on the pressure sensor 38 data and the angle sensor 13 travel data recorded in the recording module 44; the picture display module 46 displays the chart generated by the chart generation module 45 for the construction personnel to watch;

[0057] Each time the vibration plate 32 comes into contact with the small stones at the bottom, the reaction force generated by the vibration will, to a certain extent, drive the connecting rod 34 at the top of the vibration plate 32 to retract and compress the air pressure inside the air pipe 33. If the degree of vibration settlement of each small stone is uniform, the air pressure change inside the air pipe 33 detected by the pressure sensor 38 will be relatively uniform. However, when the local foundation is relatively soft or over-compacted, the force fed back by the corresponding vibration plate 32 will also be different, resulting in different air pressure changes. Once the difference between the air pressure change and the detection data of the pressure sensor 38 of other normal air pressure changes exceeds a threshold, it means that there is a problem with the small stone or foundation under the vibration plate 32, and then an alarm will be issued through the alarm module 43, and the recording module 44 will record the position of the small stone to facilitate subsequent adjustment and search work.

[0058] The vibration mechanism 2 includes a drive motor 21 and an eccentric shaft 22 fixedly mounted on the output shaft of the drive motor 21. The drive motor 21 is electrically connected to a PLC controller 42 via a wire. The PLC controller 42 conveniently controls the start and stop of the drive motor 21 and the working state, thereby adjusting the vibration amplitude and frequency.

[0059] Among them, two electric push rods 11 are fixedly installed on the vibration machine frame 1, and the output shaft ends of the two electric push rods 11 are rotatably installed with walking wheels 12. An angle sensor 13 is installed at the rotation connection between the walking wheels 12 and the electric push rods 11. The electric push rods 11 and the angle sensor 13 are electrically connected to the PLC controller 42 through wires;

[0060] Through the electric push rod 11, the walking wheel 12 can be extended to provide installation space for the two expansion vibration fixing plates 5, which is convenient for expanding the construction area of ​​the vibration machine. At the same time, the walking distance of the walking wheel 12 is detected by the angle sensor 13, and the data is uploaded to the data processing module 41, and the position of the problem small stone is determined in cooperation with the pressure sensor 38.

[0061] Example 3:

[0062] This solution also provides Example 3 based on Example 1 and Example 2:

[0063] See also Figure 1-7 A construction method of a small stone paving construction device comprises the following steps:

[0064] Step 1: According to the specifications of the small stones to be paved and the softness of the roadbed of the paved section, the PLC controller 42 in the control system 4 controls the working state of the drive motor 21 to make the vibration mechanism 2 match the corresponding vibration frequency and vibration amplitude;

[0065] Step 2: The vibration of the vibration mechanism 2 is transmitted to the small stone pressing plate 3, and the vibration plate 32 is used to vibrate and compact the small stones at the bottom to ensure that the small stones are firmly fixed on the ground;

[0066] Step 3: The pressure sensor 38 detects the pressure inside the air pipe 33 in real time when each vibration plate 32 and the small stone are feeding back. The detection data is uploaded to the data processing module 41, and the data processing module 41 analyzes the pressure change data. When the change data is greater than a set threshold, it is determined that the foundation of the small stone at the bottom of the vibration plate 32 is too loose or too solid.

[0067] Step 4: The alarm module 43 and the recording module 44 receive the analysis results of the data processing module 41. The recording module 44 records the analysis results in real time. If there is any problem with the analysis results, the alarm module 43 will issue an alarm to remind the construction personnel.

[0068] Step 5: The chart generation module 45 is used to generate a grid image based on the pressure sensor 38 data recorded in the recording module 44 and the travel data of the vibration machine frame 1. The construction personnel receive the alarm information from the alarm module 43, and find the location of individual or local problem small stones according to the image display module 46 and make adjustments, and the construction is completed.
