Abstract

PURPOSE:To improve working efficiency and to prevent the deformation of a block by detecting the right and left moving amounts of a moving structure block, and operating the deviation between the moved amounts. CONSTITUTION:A signal is outputed into a hydraulic system from a control part 38. A hydraulic cylinders 16 are operated in the direction for pulling cylinder rods 18. A block 10 is moved along rails 12 in response to the movement of the rods 18. Since the movements of sensor units 20 are uniform, wires 24 are loosened. Since winding reels 22 are always rotated in the winding direction of the wires 24, the wires 24 are slowly wound. Therefore, rotary reels 50 are rotated. The rotating amounts of the reels 50 are detected by an encoder 54 and supplied into the control part 38. The moved amounts of the wires 24 are operated in the control part 38 based on the rotating amounts of the right and left reels 50. The deviation between the moved amounts is operated and displayed on a display part. The rate of the actual deviation amount in the preset limit-deviation amount is operated and displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a measuring device for managing a traveling construction method for managing left and right deviations with respect to the moving direction of a traveling construction method.

[Prior art]

Currently, when assembling the large frame of a large space structure, there are cases where the assembly crane cannot cover the entire surface, where there are restrictions on the crane's work near railway tracks, or where there is no space around the planned construction site. The traveling construction method was applied, in which the large frame is divided into multiple blocks, assembled in a location where the crane can be operated, placed on pre-installed rails, and sequentially moved horizontally to locations beyond the reach of the crane. There is.

In this traveling construction method, hydraulic cylinders are attached to both the left and right sides of the blocks in the moving direction, and each block is horizontally moved by the operation of these hydraulic cylinders.

By doing this one after another, the assembly of the large structure is completed.
Large structures can be assembled even in locations where the range of movement of the crane is restricted.

When the hydraulic cylinder is actuated, a left-right deviation may occur during movement, and this deviation may deform the block being moved. For this reason, a device is provided that measures and displays the amount of left and right movement by the hydraulic cylinder, and the amount of left and right movement is displayed on this display device at any time.

The operator monitors the amount of left and right movement and takes corrective action if the left and right deviation exceeds a reference amount.

The correction operation is temporarily stopped when the reference amount is exceeded,
Activate only the hydraulic cylinder that is lagging behind to correct the deviation and restart.

[Problem to be solved by the invention]

However, the operator must constantly monitor the two left and right movement amount displays, which causes operator fatigue, especially eye fatigue. In addition, the timing of corrective operations, that is, the comparison with the reference amount, is left to the judgment of the operator, and if this accuracy is high and corrective operations are performed frequently, the corrective operations will take up most of the work time, and ineffective. Furthermore, if the accuracy is low and correction operations are small, the blocks will be deformed and the finish of the building will be affected.

Taking the above facts into consideration, the present invention can alleviate operator fatigue, improve work efficiency and prevent block deformation by performing deviation correction work at a fixed time regardless of the operator. The purpose is to obtain a measuring device for managing the traveling construction method.

[Means to solve the problem]

The measuring device for managing the traveling construction method according to the present invention manages left and right deviations in the moving direction of the traveling construction method, in which a structure block divided into a plurality of parts is sequentially horizontally moved along a pair of traveling rails installed in advance and assembled. A measuring device for managing a traveling construction method for the purpose of the present invention, which includes a movement amount detection means for detecting the amount of left and right movement of a structure block to be moved, and a means for calculating the deviation of the left and right movement amount, and a measuring device for measuring the amount of movement in the left and right directions of a structural block to be moved. It has a calculation means for calculating the ratio to the set deviation limit amount, and a display means for displaying the calculation result by the calculation means.

[Effect]

According to the present invention, the amount of left and right movement is detected by the movement amount detection means. A calculation means calculates the deviation of the detected left and right movement amount, and also calculates the ratio with respect to a predetermined deviation limit amount. Here, this calculated ratio is displayed by the display means. As a result, the operator only needs to pay attention to the portion where the ratio is displayed, and there is no need to monitor the amount of left and right movement.

Therefore, work efficiency is improved and fatigue level is reduced.

In addition, since the displayed ratio is the ratio to the deviation limit amount set in the reservation window, the operator only has to judge whether or not to perform an operation to correct the left and right movement amount difference based on this ratio display. Regardless of the difference, it can be carried out at a certain time during the corrected copying period, improving work efficiency and not affecting the finishing of the structure.

〔Example〕

FIG. 1 shows a block 10 in which a structure constructed by the traveling construction method is divided into a plurality of parts. The block 10 is assembled in a location that can be operated by a crane (not shown), and is placed on two mutually parallel rails 12 that have been previously installed by the crane.

A traveling shoe (not shown) is interposed between the block 10 and the rail 12, which lowers the coefficient of friction and allows the block 10 to slide along the rail 12 with a relatively small force. . Clamping devices 14 are fixed on the rails 12 at a distance slightly apart from the blocks 10, respectively. The clamp device 14 is removable and movable along the rail 12 when the clamp mechanism is released. Clamp device 14

The tips of 8 are connected. A hydraulic cylinder 16 is attached to the base of the block, and the cylinder rod 1
8 is in an extended state. Here, when a predetermined hydraulic pressure is applied to the hydraulic cylinder 16 from a hydraulic system (not shown), a force is applied in a direction in which the cylinder rod 18 is retracted.

This retracting force of the cylinder rod 18 causes the hydraulic cylinder 16 to move along the rail 12 because the tip thereof is fixed by the clamp device 14 . Therefore, by simultaneously moving the pair of hydraulic cylinders 16, the block 10 attached to the hydraulic cylinders 16 is horizontally moved along the rail 12 together with the hydraulic clamp 16. Here, the clamping state of the clamping device 14 is once released, and the cylinder rod 18 is clamped again at the position where the cylinder rod 18 is extended.
By repeating the pulling operation, the block IO can be moved to a predetermined position.

Sensor units 20 as movement amount detection means are provided on the rails 12, respectively, corresponding to the final position of the block 10. Sensor unit 2
0 is provided with a winding wheel 22, on which a wire 24 is wound. A magnet 26 is attached to the tip of the wire 24, and the magnetic force of the magnet 26 causes the wire 24 to be magnetically attached to the column 28 of the block 10.

Note that the connection between the block 10 and the wire 24 is not limited to magnetic force, and other engagement means that are easy to attach and detach, such as hooks, may be used.

As shown in FIG.
0 is connected to a rotating shaft (not shown) of a motor 34 via a clutch portion 32 and a gear box 36. This motor 34 is connected to a driver 40 of a control section 38 shown in FIG. 3, and is constantly rotated in one direction of the winding direction of the wire 24 by the winding wheel 22. For this reason, wire 2
4 is always held in a tensioned state, that is, parallel to the upper surface of the rail 12. Clutch part 3
2 is the rotating shaft 30 of the winding wheel 22 and the output shaft 35 of the gear box 36, which are stopped while the wire 24 is under tension.
It has the role of absorbing the rotation difference between the

Furthermore, thin circular plates 42 and 44 on which black and white bars (not shown) are printed alternately are attached to the rotating shafts 30 and 35, respectively. An incretor 46.48 connected to the control unit 38 is disposed on the outer periphery of the disc 42.44 so as to sandwich the vicinity of the outer periphery, and monitors the rotational state of the rotary shaft 30.35.

The wire 24 is wound one or more turns around the rotating reel 50 between the take-up reel 22 and the tip.

With this arrangement, the rotating reel 50 is rotated in accordance with the movement of the wire 24 in the axial direction. rotating reel 50
The rotation of the rotating shaft 52 is detected by an encoder 54. The encoder 54 is connected to the control unit 38, and the amount of rotation of the rotary reel 50 can be recognized based on the output signal from the encoder 54.

As shown in FIG. 3, the control section 38 and the sensor unit 2
0 through a harness 58. The control unit 38 includes a microcomputer 60. The microcomputer 60 includes a CPU 62, an RA
It is composed of an M64, a ROM 66, an input/output port 8, and a bus 70 such as a data bus or a control bus that connects these.

The signal lines of the driver 40, encoder 54, and interrupters 46 and 48 are also connected to the attendance cupboard door 2. Furthermore, an indicator lamp, a switch, etc., which will be described later, are connected to the input/output capotro 8.

As shown in FIG. 4, the front panel 74 of the control B 38 has 7 segment LED display sections 76, 78, .
80 are arranged in parallel (hereinafter simply referred to as display section 7G, 78.8
0). The left and right display sections 76 and 80 indicate the encoder 5.
The amount of movement of the left and right wires 24 calculated based on the amount of rotation of the rotating reel 50 detected by 4 is displayed in mm units. Further, the central display section 78 displays the deviation calculated based on the amount of left and right movement displayed on the display sections 76 and 80 in units of mm.

Below each display section 76.80 are provided deviation standard buttons 82.84 that determine the standard for calculating the deviation, and by operating either one of the deviation standard buttons 82 (84), The deviation is calculated based on the movement of the operated side. Further, distance calibration buttons 86.88 are provided below each deviation reference button 82.84, 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 driving 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. The increase button 90 and decrease button 92 are also applied when setting the deviation limit amount. That is, a deviation limit amount setting button 94 is provided below the decrease button 92, and when this deviation limit amount setting button 94 is operated, the deviation limit amount is displayed on the display section 78. It has become. This 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. The deviation limit amount can be changed by operating the increase switch 90 or decrease switch 92 while the deviation limit amount setting button 94 is being operated.

Above the power switch 96 installed at the lower left of the front panel 74, there are provided a reset button 98 for resetting the display on the display section 76, 78, 80, and an abnormality lamp 100 for reporting an abnormality in the power supply. Also, the front panel 7
4 is provided with a selection switch 102 for selecting whether the winding direction of the wire 24 by the winding rule 22 is positive or the drawing direction is positive.

A plurality of lamps 104 are arranged in the vertically intermediate portion of the front panel 74 in the left-right direction.

These lamps 104 are designed to display the ratio of the deviation amount to the deviation limit amount calculated by the control unit 38, and are evenly distributed to the left and right with the center lamp 104A as a reference, so that a total of 19 lamps are lined up. I'm here. The center lamp 104A has a scale display of 10%,
Further, a 50% scale display is attached to the fifth lamp 104B on the left and right when counting from the central lamp 104A.

Further, a 100% scale display is attached to the ninth lamp 104C on the left and right when counting from the center lamp 104A.

Furthermore, the outermost left and right lamps 104D have a ratio of 1.
It is controlled to blink when it exceeds 00%.

Here, the calculation result of the deviation in the control unit 38 is calculated by the lamp 10.
It can be visually checked by the lighting position and number of lights in 4. For example, if the deviation amount on the left is 30% relative to the limit deviation amount.
%, the central lamp 104A and the two lamps 104 to the left thereof are turned on.

The operation of this embodiment will be explained below.

When the block 10 is assembled, the rail 1 is moved by a crane.
2. Here, a hydraulic cylinder 16 is fixed to this block 10, and furthermore, a clamping device 14 connected to the tip of a cylinder rod 18 of this hydraulic cylinder 16 is clamped to the rail 12 with the cylinder rod 18 extended. Next, the magnet 26 attached to the tip of the wire 24 drawn out from the sensor unit 20 is magnetically attached to the column 28 of the block 10.

Next, the movement amount management control will be explained according to the flowchart shown in FIG. First, in step 20Q, the power switch 96 on the front panel 74 of the control unit 38 is turned on, the reset button 98 is operated, and the display 876.78.
80 are all cleared (step 202).

Next, in step 204, the selection switch 1 is used to select whether the winding direction of the wire 24 is positive or the drawing direction is positive.
02 and operate the deviation limit amount setting button 94 (
Step 206). This allows the deviation limit amount setting button 9
4 itself lights up and enters the setting mode. For example, ±30
When setting +nm as the limit amount, operate the increase button 90 and keep pressing it until the display section 78 shows 30. When the display section 78 shows 30, the operation of the increase button 90 is stopped, and the deviation limit amount setting button 94 is operated again to be in a non-operated state. As a result, the deviation limit amount setting button 94 itself is turned off, and the operation mode is entered. Next, in step 208, one of the deviation reference buttons 82 and 84 is operated to determine which of the left and right standards should be used to display the deviation amount. The operated deviation reference button 82 (84) 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 operated in a direction to retract the cylinder rod 18. In response to this movement of the cylinder rod 18, the block 10 is moved along the rail 12.

This movement is smooth because the friction coefficient is extremely small due to the traveling shoe.

When the block 10 moves, the wire 24 becomes slack because the movement of the sensor unit 20 is constant, but the wire 24 is rotated in the direction in which the take-up reel 22 is always driven by the motor 34 to wind the wire 24. Therefore, as the block 10 moves, it is gradually wound up. Therefore, the rotary reel 50 on which the wire 24 is spirally wound around the intermediate portion of the wire 24 rotates. rotating reel 50
The amount of rotation is detected by the encoder 54, and the amount of rotation is detected by the encoder 54.
8 (step 212). In the control unit 38,
The amount of movement of the wire 24 is calculated from the amount of rotation of the left and right rotating reels 50 (step 214), and is displayed on the display sections 76 and 80, respectively (step 216). In addition, the deviation of these moving amounts is calculated (step 218), and the display B7g
is displayed (step 220). Here, just by looking at the display of this deviation, it is not possible to grasp the proportion to the total amount of movement of the hydraulic cylinder in one day, and it is unclear whether it should be corrected or not. Therefore, in this embodiment, step 222.2
At step 24, the ratio of the actual deviation amount to the reserved limit deviation amount, taking into account the total movement amount of the hydraulic cylinder 16, etc., is calculated and displayed. That is, if the calculation result is that the amount of movement on the left side is 30% of the amount of movement on the right side, the center lamp 10A and the two lamps 104 on the left side thereof are turned on.

This allows the operator to instantly determine whether or not a corrective operation is necessary (step 226).

If a corrective operation is not required, the process moves from step 226 to step 210, and when the cylinder rod 18 has been retracted, the clamp 14 is released, the clamp device 14 is moved along the rail 12, and the cylinder rod 18 is retracted. The block 10 is clamped again in the extended state, and the hydraulic cylinder 16 is operated to move the block 10. By repeating this, the block 10 can be moved to a predetermined position. Further, if a correction operation is required in step 226, the process moves to step 228, where a predetermined correction operation is performed, and then the process moves to step 210.

According to this embodiment, the operator does not have to constantly monitor the amount of left and right movement or the display of deviations thereof, and the lamp 104
It is only necessary to check the 0 lighting position and the number of lighting lights, which can reduce the degree of fatigue caused by tension and improve work efficiency.

In addition, if the correction operation is performed just before the limit while the lamp 10 is lit, it is possible to suppress the difference in correction operation timing due to different operators and obtain a constant correction operation timing. deformation can be prevented, and a decrease in work efficiency due to excessive correction operations can be suppressed.

In this embodiment, block 1 is used as the movement amount detection means.
Although the encoder 54 measures the amount of movement of the wire 24 under tension at 0, it is also possible to directly contact the peripheral surface of the roller with the block 10 and detect the amount of rotation of the roller.
A means for detecting the amount of movement of the ground, such as a light wave distance meter, may be used.

〔Effect of the invention〕

As explained above, the measuring device for traveling construction method management according to the present invention can alleviate operator fatigue.
By performing the deviation correction work at a fixed time regardless of the operator, there is an excellent effect that work efficiency can be improved and deformation of the block can be prevented.
