Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a measuring method for managing a traveling method for managing a deviation of a traveling method in a left-right direction with respect to a moving direction.

(Prior art)

At present, when assembling large structures, large cranes cannot cover the entire surface, or there are restrictions on crane work along railway tracks, etc., and there is no room around the planned construction site The traveling construction method is applied in which the large frame is divided into a plurality of blocks and assembled in a place where the crane can be operated, placed on a rail that has been set in advance, and moved horizontally horizontally to a place where the crane cannot reach. I have.

In this traveling method, hydraulic cylinders are mounted on the left and right sides of the block in the moving direction, and the hydraulic cylinders are moved horizontally by one block by the operation of the hydraulic cylinder.

By sequentially performing this, the assembly of the large frame is completed, and even in a place where the moving range of the crane is limited,
A large frame can be assembled.

When the hydraulic cylinder is operated, a left-right deviation may occur during the movement, and the moved block may be deformed by the deviation. For this reason, a device for measuring and displaying the amount of left and right movement by the hydraulic cylinder is provided, and this display device is configured to display the amount of left and right movement as needed. The operator monitors the left and right movement amounts, and performs a correction operation when the left and right deviation exceeds the reference amount. The correction operation is performed by temporarily stopping when the reference amount is exceeded, correcting the deviation by operating only the hydraulic cylinder that is behind, and restarting.

[Problems to be solved by the invention]

However, the operator needs to constantly monitor the display of the two movement amounts on the left and right, which causes operator fatigue, particularly eye fatigue. Also, the timing of performing the correction operation, that is, the comparison with the reference amount, is left to the judgment of the operator. If the correction operation is performed with high accuracy and frequent, the correction operation consumes most of the work time, ineffective. If the accuracy is low and the number of correction operations is small, the blocks are deformed, which affects the finish of the building.

In consideration of the above facts, the present invention can reduce the fatigue of the operator, improve the work efficiency and prevent the deformation of the block by performing the work of correcting the deviation at a certain time regardless of the difference of the operator. It is an object of the present invention to obtain a measuring device for managing a traveling method that can perform the method.

[Means for solving the problem]

The measuring method for managing a traveling method according to the present invention manages the deviation between the left and right with respect to the moving direction of the traveling method, in which a plurality of divided structural blocks are sequentially horizontally moved along a pair of traveling rails installed in advance. A moving amount detecting means for detecting left and right moving amounts of a structure block to be moved, and a deviation of the left and right moving amounts for a left moving amount and a right moving amount. And a calculating means for calculating a ratio to a preset deviation limit based on the deviation, including a plurality of lamps arranged in the left-right direction, and an arrangement center of the plurality of lamps. The number of the lamps on the opposite side to either one of the left and right as a reference when calculating the deviation is the number corresponding to the ratio to the deviation limit amount. It has a display means for lighting, a.

[Action]

According to the present invention, the left and right movement amounts are respectively detected by the movement amount detection means. The detected left and right movement amounts are calculated by calculating means based on one of the left movement amount and the right movement amount, and a deviation set in advance based on the deviation. The ratio to the limit is calculated. Here, the calculated ratio is indicated by a display unit including a plurality of lamps arranged in the horizontal direction.
This is displayed by lighting the number of lamps on the side opposite to one of the left and right sides as a reference when calculating the deviation with respect to the arrangement center of the plurality of lamps in accordance with the ratio to the deviation limit amount. Thus, the operator only needs to pay attention to the portion where the ratio is displayed, and does not need to monitor the left and right movement amounts. For this reason, workability is improved and the degree of fatigue is reduced. Further, since the displayed ratio is a ratio with respect to the predetermined deviation limit amount, the operator only has to determine whether or not to perform the correction operation of the difference between the left and right movement amounts based on the displayed ratio, and the difference between the operators is different. Regardless, the correction operation can be performed at a fixed time, so that the working efficiency can be improved and the finishing of the structure is not affected.

Is connected to the driver 40 of the control unit 38 shown in FIG. 3, and the winding reel 22 constantly rotates the wire 24 in one winding direction. For this reason, the wire 24 is always kept in a tensioned state, that is, in a state of being parallel to the upper surface of the rail 12. The clutch part 32 has a function of absorbing a rotation difference between the rotation shaft 30 of the take-up reel 22 and the output shaft 35 of the gear box 36, which are stopped in a state where the wire 24 is tightened.

Further, thin disks 42 and 44 on which black and white bars (not shown) are alternately printed are attached to the rotating shafts 30 and 35, respectively.

As shown in FIG. 4, a 7-segment LED display section 76, 78, 80 is arranged above the front panel 74 of the control section 38 (hereinafter simply referred to as display sections 76, 78, 80). The left and right display units 76 and 80 are configured to display the amount of movement of the left and right wires 24 calculated in mm based on the amount of rotation of the rotating reel 50 detected by the encoder 54.

Below the display units 76 and 80, deviation reference buttons 82 and 84 for determining the reference when calculating the deviation are provided, and by operating one of the deviation reference buttons 82 (84), The deviation is calculated based on the movement of the operated side. Further, distance calibration buttons 86 and 88 are provided below the respective deviation reference buttons 82 and 84, and are operated when calibrating the left and right distances. The distance calibration buttons 86 and 88 have built-in lamps, which are turned on in the calibration mode and turned off in the operation mode. When the distance calibration buttons 86 and 88 are operated, the left and right distances are calibrated by operating the increase button 90 and the decrease button 92 provided at the center of the front panel 74, respectively. Further, the increase button 90 and the decrease button 92 are also applied when setting a deviation limit amount. That is, a deviation limit amount setting button 94 is provided below the decrease button 92, and when the deviation limit amount setting button 94 is operated, the display unit 78 displays
The deviation limit is displayed. The deviation limit amount setting button 94 has a built-in lamp and is turned on in the deviation limit setting mode and turned off in the operation mode. By operating the increasing switch 90 or the decreasing switch 92 while the deviation limit amount setting button 94 is being operated, the deviation limit amount can be changed.

Above a power switch 96 provided at the lower left of the front panel 74, a reset button 98 for resetting the display of the display units 76, 78, and 80 and an abnormal lamp 10 for notifying an abnormal power supply.
0 is provided. A selection switch 10 for selecting whether the winding direction of the wire 24 by the winding reel 22 is plus or the drawing direction is plus is provided at the lower right of the front panel 74.
Two are provided.

A plurality of lamps 104 are arranged in the middle part of the front panel 74 in the up-down direction in the left-right direction. This lamp 104

For example, when the left deviation amount is calculated to be 30% with respect to the deviation limit amount. Is a configuration in which a center lamp 104A and two lamps 104 on the left side thereof are turned on.

 The operation of the present embodiment will be described below.

When the block 10 is assembled, the rail 12
Placed on top. Here, a hydraulic cylinder 16 is fixed to the block 10, and a clamp device 14 connected to a tip of a cylinder rod 18 of the hydraulic cylinder 16 is clamped to the rail 12 with the cylinder rod 18 extended. Next, a magnet 26 attached to the tip of the wire 24 drawn from the sensor nit 20 is magnetically attached to the column 28 of the block 10.

Next, the movement amount management control will be described with reference to the flowchart of FIG. First, in step 200, the power switch 96 on the front panel 74 of the control section 38 is turned on, and the reset button 98 is operated to clear all the displays on the display sections 76, 78 and 80 (step 202). Then, step 2
In 04, the selection switch 102 selects whether the winding direction of the wire 24 is positive or the pulling direction is positive, and the deviation limit amount setting button 94 is operated (step 206). As a result, the deviation limit amount setting button 94 itself is turned on, and the setting mode is set. For example, when ± 30 mm is the limit amount, the increase button 90 is operated and kept pressed until the display on the display unit 78 becomes 30. When the display 78 shows 30, the increase button 90
Operation is stopped, and the deviation limit amount setting button 94 is operated again to bring it into the non-operation state. As a result, the deviation limit amount setting button 94 itself is turned off, and the operation mode is set. Next, at step 208, one of the deviation reference buttons 82 and 84 is operated to
It is determined which of the right and left is to be used as a reference for displaying the deviation amount.
The deviation reference button 82 (84) on the operated side lights up.

Here, in step 210, a signal is output from the control unit 38 to the hydraulic system, and the hydraulic cylinder 16 is moved to the cylinder rod 18.
It is operated in the direction of pulling in. This cylinder rod 18
The block 10 is moved along the rail 12 in response to the movement. This movement moves smoothly because the friction coefficient is extremely small due to the traveling shot.

When the block 10 moves, the sensor unit 20 moves at a constant rate, so that the wire 24 is slackened.
Since the block 24 is rotated in the winding direction, the block 24 is gradually wound up as the block 10 moves. Therefore, the rotating reel 50 around which the wire 24 is spirally wound around the intermediate portion of the wire 24 rotates. The amount of rotation of the rotating reel 50 is determined by the encoder 54.
And is supplied to the control unit 38 (step 21
2). The controller 38 calculates the amount of movement of the wire 24 from the amount of rotation of the left and right rotating reels 50 (step 214).
Displayed on 6 and 80 respectively (step 216). The deviation of these movement amounts is calculated (step 218), and the
Displayed at step 8 (step 220). Here, only by looking at the display of the deviation, the ratio of the hydraulic cylinder 16 to the total movement amount cannot be grasped, and it is not exactly known whether it should be corrected or not. Therefore, in this embodiment, in steps 222 and 224, the ratio of the actual deviation amount to the preset limit deviation amount is calculated and displayed in consideration of the total movement amount of the hydraulic cylinder 16, and the like. That is, if the result of the calculation indicates that the left movement amount is 30% of the right movement amount, the central lamp 10A and the two left lamps 104 are turned on. This allows
The operator can instantaneously determine whether a corrective operation is required (step 226).

If no corrective action is required, go to step 226 and step 2
When the cylinder rod 18 is retracted, the clamp 14 is released, the clamp device 14 is moved along the rail 12, and the cylinder rod 18 is re-clamped with the cylinder rod 18 extended. By operating the cylinder 16, the block 10 is moved. By repeating this, the block 10 can be moved to a predetermined position.
If a corrective operation is required in step 226, the process proceeds to step 228, where a predetermined corrective operation is performed.
Move to 10.

According to the present embodiment, the operator need not always monitor the display of the left and right movement amounts and their deviations.
It is sufficient to confirm the lighting position and the number of lighting, and the degree of fatigue due to tension can be reduced, and workability can be improved.
Further, if the correction operation is performed immediately before the limit in the lighting state of the lamp 104, it is possible to suppress the difference in the correction operation time due to the difference between the operators and obtain a constant correction operation time. Deformation of the block 10 due to a delay in the correction operation can be prevented, and a decrease in work efficiency due to excessive correction operation can be suppressed.

In this embodiment, a block is used as the moving amount detecting means.
Encoder for the amount of movement of wire 24 that has been strained for 10 movements
Although the measurement is performed at 54, the peripheral surface of the roller may be brought into direct contact with the block 10 to detect by the rotation amount of the roller, or other movement amount detection means such as an optical distance meter may be used.

〔The invention's effect〕

As described above, the measuring method for managing a traveling method according to the present invention can alleviate operator fatigue and improve the work efficiency by performing the work of correcting the deviation at a fixed time regardless of the difference of the operator. And has an excellent effect that the deformation of the block can be prevented.
