Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compaction work management device for managing compaction work in civil engineering work.

This type of compaction work is performed using compaction machines such as road rollers and compactors, and the compaction machine uses pressure from the weight of the front wheels and rear wheels, or when it has a built-in vibration mechanism, it generates vibrations. Vibration is applied to the wheels using force to compact earth and sand. and,
In the compaction work, these compaction machines are used to repeatedly move forward and backward at the same location a predetermined number of times to compact earth and sand, that is, to perform compaction.

In this compaction work, the conditions of the compaction work are determined depending on the type of compaction machine used, the type of earth and sand to be compacted, the degree of moisture content, etc. etc. are determined. This compaction work must be carried out reliably in accordance with the determined conditions, and the quality of the work determines the quality of the completed construction, so management of the work is important.

However, the current work management method relies entirely on manual labor, relying on the memories and notes of the rolling machine operator and his assistants, and has no means of confirmation. In addition, this type of rolling work is monotonous, and the number of times it is counted is likely to be miscounted over a long period of time, which poses problems in terms of work management.Therefore, there has been a need for a highly stable rolling work management device.

In view of the above points, the present invention has been made to solve such problems and satisfy such demands.The purpose of the present invention is to completely eliminate the need for manual compaction work, which has hitherto been impossible to accurately control. The work data can be collected automatically, which enables numerical control from the quality control point of view, labor-saving from the work management point of view, and furthermore, from the labor management point of view. An object of the present invention is to provide a compaction work management device that enables work management.

To achieve this purpose, the present invention automatically collects data related to work content during work,
The system is designed to print out documents such as daily reports after work is completed, and embodiments of the present invention will be described in detail below with reference to the drawings.

5 is a running detection plate attached to the rear wheel 3b of the compaction machine body 2, and 5 is a running sensor attached to the frame of the compaction machine body 2. This running sensor 5 detects the rotation direction of the running detection plate 4. It consists of a plurality of running state detection parts, for example two proximity switches, mounted on a frame at detectable positions.

In FIG. 1, when the compaction work is being performed, as the rear wheel 3b rotates, the travel detection plate 4 detects the movement of the rear wheel in the vicinity of the travel sensor 5 from above to below, or from below to above. 3b repeatedly passes in a fixed direction determined by the rolling direction, once every rotation.

FIG. 2 is a configuration diagram showing an embodiment of the rolling compaction work management device according to the present invention. In FIG. 2, parts labeled with the same numbers as in FIG. 1 indicate the same equipment.

In the figure, the running sensor 5 is composed of running sensors 5-1, 5-2 which are two proximity switches. The two operating orders are configured to be different. Therefore, by calculating and processing the output signals sent from the traveling sensor 5-1 and the traveling sensor 5-2, the rolling direction,
Transformation speed and compaction distance can be determined.

Reference numeral 6 denotes a vibration sensor, and this vibration sensor 6 is designed to detect the state of vibrations applied to the wheels of the compaction machine body 2 shown in FIG. 1, such as the frequency, and to measure the vibrations applied to the wheels. It is composed of Reference numeral 7 denotes a work management unit which takes the output signal of the traveling sensor 5 and the output signal of the vibration sensor 6 as input signals and processes the output signals of the traveling sensor 5 and the vibration sensor 6.This work management unit 7 sets the number of compactions. a setting device to display the number of times the rolling compaction operation has been performed, a judgment circuit that compares the preset number of compacting operations with the number of times the rolling compaction operation has been performed and detects when the two match, and the rolling speed and rolling pressure. It has a built-in calculation processing circuit that calculates distance. and,
This work management unit 7 is configured to sound a buzzer 8 when the determination circuit determines a match, and also controls the number of rolling operations, number of times of rolling execution, and match set for the data pack holder, which will be described later. It is configured to output information (data) such as signals, rolling speed, rolling distance, and vibration frequency.

9 is a data pack holder which receives the output signal from the work management unit 7 and the on/off signal from the engine key switch 11 as input signals, and outputs data to the inserted data pack 10;
The processing results obtained by the work management unit 7 are configured to be temporarily stored in a portable data pack 10. Here, this data pack 1
The data pack holder 9 has a temporary data storage function and a clock function that are compensated for by a power outage using a battery or the like.
It is configured to sequentially temporarily store the data inputted from the computer, and to add a time stamp as necessary.

Reference numeral 12 denotes a data pack reader that reads data temporarily stored in the data pack 10. As mentioned above, this data pack reader 12 has the function of reading the data temporarily stored in the data pack 10 and transferring it to the master, which will be described later. It also has the function of correcting the time of the clock in the data pack 10 based on commands from the master. 13 is a master that processes the data read from the data pack reader 12, and this master 13 creates daily and weekly reports as necessary based on the data input from the data pack reader 12, and also creates necessary for work management. The printer 14 is configured to print out the results of processing various management tables for each machine, work type, worker, etc., either regularly or at any time.

Reference numeral 15 indicates various management tables (forms) printed out from the printer 14.

Next, the operation of the embodiment shown in FIG. 2 will be explained using an example of an actual operating method.

First, the data pack 10 is distributed in advance to operators of individual rolling compaction machines or to individual rolling compaction machines.

Then, when the operator comes to work in the morning, finishes the work meeting, and leaves the field office for the work site, he inserts the corresponding data pack 10 into the data pack reader 12 installed at the field office. Master 1
Step 3 confirms that the memory contents of the temporary memory circuit of the data pack 10 have been cleared via the data pack reader 12, and in conjunction with this, corrects the time on the clock built into the data pack reader 12, and then , write the year, month, day, etc. of the current day as necessary.

The operator of the rolling machine carries the data pack 10 with him, goes to the target rolling machine, inserts the data pack 10 into the data pack holder 9 attached to the rolling machine, and then starts work. Set the number of compactions for the day on the setting device of the management unit 7,
Start compaction work.

Next, when the rolling machine starts work, the running detection plate 4 rotates together with the front wheels 3a and the rear wheels 3b (see FIG. 1) and passes close to the running sensor 5. When traveling in the same direction, the travel detection plate 4 repeatedly passes close to the travel sensor 5 in the same direction, so the work management unit 7 detects this state and calculates the number of rollings by (+)1. shall be. Then, when the rolling machine finishes traveling the specified distance,
Then start driving in the opposite direction. In this case, since the running detection plate 4 passes close to the running sensor 5 in the opposite direction, the order of the output signals of the running sensor 5 is reversed.

In this way, in the work management unit 7, the number of times of rolling is set to (+)1 by repeatedly detecting the reverse state. Similarly, each time the rolling machine travels in the opposite direction, the number of rollings is set to (+)1, and when the total number of rolling matches the preset number, the buzzer 8 sounds and the number of rolling Notifies that the specified number has been reached. Therefore, after the rolling machine has traveled a preset specified distance, when it starts traveling in the opposite direction, it moves to a new traveling direction, and at the same time as the rolling machine starts rolling work, the display of the work management unit 7 also changes. start displaying. Various data during these operations are automatically stored in the data pack 10 via the data pack holder 9 together with vibration data based on vibrations from the vibration sensor 6 applied to the wheels.

On the other hand, when the operator of the rolling machine finishes work and leaves the rolling machine, he pulls out the data pack 10 from the data pack holder 9 and takes it back to the field office. 10 is inserted into a data pack reader 12, the data pack reader 12 reads the work data of the day, stores the read data in a master 13, and clears the data stored in the data pack 10.

The data accumulated in the master 13 is processed as necessary, and various management forms 1
5 from the printer 14.

As described above, by using the apparatus of the present invention, various types of work information can be automatically collected with almost no human intervention in rolling compaction work, which has hitherto been impossible to accurately manage.

Based on this information, numerical management becomes possible from the viewpoint of quality control, labor is saved from the viewpoint of work management, and labor management becomes possible from the viewpoint of labor management.

As explained above, according to the present invention, various information related to the work contents can be automatically collected during compaction work, and documents such as daily reports can be printed out after completion of compaction work. Therefore, the practical effect is extremely large. In addition, since there is no need to rely on manual labor as in the past, it is not only possible to solve all the inconveniences and uncertainties caused by this, but also to be able to manage numerically from the standpoint of quality control, which is useful from the standpoint of work management. It saves labor and is extremely effective in terms of labor management.
