PURPOSE:To bore a fitting hole of a inflow pipe without forming a marking-off line in a body block, by a method wherein a moving device, rotary device and boring device are controlled by data of a boring position with an input device, data of a reference position with a detecting device and the diameter of a pipe with a measuring device. CONSTITUTION:A fitting position of an inflow pipe 12 of a manhole main body 1 is calculated by making a reference position 0 of a body block 4 into a basic point beforehand and applied to a control device 36 through an input device. Then the block 4 is moved in an axial direction by a moving device 22, the reference position provided on the block 4 is detected by a detecting device 29 and the diameter of a pipe is measured by a measuring device 30. Then the block 4 is turned according to a distance or an angle of a circumferential direction of data of a boring position applied to the control device beforehand and moved up to a position of a boring device 32 in an axial direction. In this instance, when the block 4 is moved by a distance obtained by adding a distance of an axial direction of the data of the boring position applied to the control device beforehand to a distance L between the boring device 32 and detecting device 29, a position of the block 4 facing on the boring device 32 becomes the boring position of a fitting hole of the inflow pipe.

Description

It is related to. Conventional technology> Conventionally, when forming holes for attaching inflow pipes, outflow pipes, etc. to the side wall of the manhole body, there were methods such as punching in cast-in-place concrete, drilling by hand, or Methods have been implemented for precast concrete pipes, such as inserting punched forms into predetermined positions during formwork assembly. These methods have poor workability and are difficult to form holes with good precision. The applicant has developed a method of drilling holes for inflow pipes in the frame block of the manhole body to solve the above problem (Japanese Patent Publication No. 62-42095). When shipping pipes such as frame blocks or straight wall pipes for manhole bodies produced in The hole for attaching the inflow pipe is defined by creating a score line based on the head difference with the inflow pipe and the angle of the inflow pipe based on the outflow pipe, and drilling a hole at the position of the score line. With this technology, holes for attaching outflow pipes and inflow pipes to pipes can be formed before shipment from the factory, making it possible to obtain reliable and inexpensive pipes.Also, it is possible to form manholes in a short time. This has effects such as being able to carry out construction work of the main body.

<Problems to be Solved by the Invention> The above technology relates to a method of drilling a hole for attaching an inflow pipe to a manhole body block, etc., and when drilling a hole in a manhole body block, etc., Two steps are required: marking work and drilling work.

Therefore, there is a demand for the development of an apparatus that can complete the drilling work for a building block or the like in one step.

An object of the present invention is to provide a drilling device that can drill holes for attaching inflow pipes and outflow pipes without forming score lines on pipes such as frame blocks for manhole bodies or straight wall pipes. This is what we intend to provide. <Means for solving intelligence problems> Above! The drilling device for a pipe such as a frame block according to the present invention which solves problem i is for relatively moving the frame block for a manhole main body or a pipe such as a straight wall pipe, the detection means, and the measurement means in the axial direction. a moving means for rotating the pipe, a rotating means for drilling the pipe, and a drilling means for drilling the pipe.

Another drilling device for pipes such as building blocks, etc. attaches a sheet that converts drilling position information into code information and displays it to the pipes of building blocks, etc., and reads the code information. It is recommended that a code reader be installed for this purpose. Effect> According to the first means, a hole for attaching a pipe such as an inflow pipe or an outflow pipe to a pipe such as a manhole body frame block or a straight wall pipe can be automatically drilled.

That is, the installation position of the inflow pipe, etc. is calculated in advance based on the longitudinal sectional view and plan view of the manhole body, or the measured value, using the reference position of the frame block as a reference point, and the calculated value is used as drilling position information for the frame block, etc., and manually drilled. input to the control means via the means. Then, the main body block, etc. is moved in the axial direction by the moving means, the reference position provided on the main body block, etc. is detected by the detection means, and the diameter of the pipe is measured by the measuring means. The frame block, etc. is rotated according to the distance or angle in the circumferential direction in the hole position information, and the crane block, etc. is further moved in the axial direction to the position of the hole drilling means. At this time, since the drilling means and the detection means are arranged at a predetermined distance apart, the body block etc. is separated by the distance in the axial direction of the drilling position information manually inputted in advance. By moving it, the position of the frame block, etc. facing the drilling means becomes the position for drilling holes for attaching inflow pipes, etc. Therefore, by fixing the frame block or the like at the above-mentioned position and driving the hole-drilling means by the control means, it is possible to drill a hole in the frame block or the like to attach an inflow pipe or the like.

There is. That is, by fixing the diameter measurement sensor 30 to the bracket 27a of the frame 27, the distance between the sensor 30 and the turning rollers 25a, 25b is kept constant. Therefore, by measuring the distance between the diameter measurement sensor 30 and the surface of the tube 4.5, it is possible to calculate the outer diameter of the tube 4.5.

The outer diameter dimensions of the tubes 4 and 5 are standardized.

Therefore, the distance between the surface of the tube 4.5 and the diameter measurement sensor 30, which corresponds to the outer diameter of the tubes 4, 5, is stored in advance in a chart in the control section 36, which will be described later, and the distance measured by the sensor 30 is stored in advance. By matching with the chart above, tube 4,
It is also possible to measure the outer diameter of 5.

The length measurement sensor 3l is not necessarily necessary for the drilling apparatus according to the present invention. However, the pipe 4 supplied to the drilling device A,
It is preferable to provide the length measurement sensor 30 in order to confirm whether or not the length 5 corresponds to the one instructed for drilling work. That is, by measuring the outer diameter and length of the actual tubes 4 and 5 and comparing the measured values with manually entered information, it is possible to determine whether the measured tube 45 matches the specified tube 4.5. It is possible to check whether

The hole drilling means 32 includes a circular cutter 32b rotatably provided on the bracket 32a, a motor 32C that drives the cutter 32b, and a motor 32C that moves the bracket 32a in the vertical direction (arrow C).

Height h+.13 from reference position 0. A sheet 33 on which information such as IO and angles θ1θ8) is coded and displayed is attached.

The sheet 33 functions as a work instruction sheet that is transferred together with the tubes 4 and 5 for each process.

Therefore, in the hole drilling device A, by reading the sheet 33 with the code reader 34, the hole 1) is drilled into the control part 36.
．． The system is configured so that 13 drilling position information can be manually input. In FIG. 1, reference numeral 35 denotes a control panel in which a control section 36 for controlling the drilling device A, a keyboard 37 serving as a manual means for inputting drilling position information, etc. are provided.

Next, the control system of the drilling device A constructed as described above will be explained using FIG. In the figure, the control unit 36 includes a CPU 36a and a drilling device A.

The above-mentioned information for 5 can be input using either the keyboard 37 or the code reader 34. The drivers 39 to 41 are for driving the motor 24 that moves the cart 22 in the directions of arrows a and b, the motor 26 that rotates the turning roller 25a, and the motor 32c that rotates the cutter 32b of the hole drilling means. Rotary encoder 42. Reference numerals 43 detect the amount of movement of the cart 22 and the amount of rotation of the tubes 4 and 5, respectively. Next, the hole 1) for the pipe 4.5 is drilled by the drilling device A configured as described above. The drilling work in No. 13 will be explained. First, the cart 22 is moved to the outside of the drilling device A in the direction of arrow b, and the pipes 4 and 5 are transported by a transport device (not shown).
Place it on turning rollers 25a and 25b. Then, by driving the turning roller 25a, the pipe 4.5 is visually inspected.
Step 14 is moved to a position below the position detection sensor 29, and the turning roller 25a is stopped. This state is taken as the origin of the tube 4.5 in the circumferential direction. At this time, tube 4,
If the seat 33 is attached to the tube 4.5, the code information of the seat 33 is read by the code reader 34, and if the seat 33 is not attached to the tube 4.5, the operator is connected to the tube 4 via the keyboard 37
Input the drilling position information for No. 5 and information such as the diameter and length of the pipe.

After the step 14 of the tube 4.5 is positioned upward as described above, the keyboard 37 is used to instruct the start of the operation program.

With the start of the operation program, the cart 22 moves in the direction of arrow a, and the position detection sensor 29 detects the pipe ends 4a, 5a of the pipe 4.5. When the position detection sensor 29 detects the pipe ends 4a, 5a of the pipes 4, 5, this detection signal is transferred to the control unit 36, which stores the position of the cart 22 at this time as the origin in the longitudinal direction of the pipes 4, 5. , the reference position 0 of the tube 4.5 is detected by the origin in the elongated direction and the origin in the circumferential direction. ? The position detection sensor 29 detects the pipe ends 4a, 5 of the pipe 4.5.
After detecting a, the diameter measurement sensor 30 measures the outer diameter of the tubes 4 and 5, and the measurement data is transferred to the control unit 36. Thereafter, while moving the trolley 22 in the direction of arrow a, the length measurement sensor 31 measures the length of the tube 4.5, and the measured data is transferred to the control section 36.

The control unit 36 compares the transferred pipe diameter data and pipe length data with the pipe diameter data and pipe length data that have been manually inputted in advance, and if these data match, the work is continued and the process is completed. If not, stop the work. In addition, the pipe diameter data and the input angle θ. θ2, the amount of rotation t,,i■ for the tube 4.5 is calculated.

Here, the pipe supplied to Katreiso fiA is connected to the frame bronc 4.
, and holes 1) are formed in the frame block 4. The case where hole No. 13 is drilled will be explained.

The outer diameter and length of the frame block 4 supplied as described above are measured, and if the frame block 4 matches the work instruction, the cart 22 continues to move in the direction of arrow a. The amount of movement of the trolley 22 is determined by the position detection sensor 2.
Hole 1) to be drilled at a distance ML between the hole and the hole drilling means 32
The distance is the sum of the height h. Therefore, the number of pulses of the rotary encoder 42 is counted based on the position of the cart 22 when the position detection sensor 29 detects the tube end 4a of the frame block 4, and when the total number of pulses matches the amount of movement, The trolley 22 stops at .

When the cart 22 is below the position detection sensor 29 or below the hole drilling means 32, the turning roller 25a is driven to rotate the frame block 4. The amount of rotation is equal to the circumferential length 1) corresponding to the intersection angle θ1 between the reference position 0 and the hole 1). Due to the rotation, the position of the frame block 4 facing the cutter 32b becomes the drilling position of the hole l1. For this reason, step l of the building block 4
The number of pulses of the rotary encoder 43 is counted based on the position of the turning roller 25b when the turning roller 25b is opposed to the position detection sensor 29, and when the total number of pulses matches the rotation amount, the turning roller 25a stops. .

The cutter 32 is located at the hole 1) to be drilled in the frame block 4.
When facing b, the motor 32C is driven, the vertical mechanism 32d is operated, and the cutter 32b rotates while approaching the frame bronch 4 to drill the hole 1). After drilling hole 1), if hole 13 is subsequently drilled, the difference between the height h+ of hole 1) and the height h of hole 13, that is,
The amount of movement corresponding to the head h is instructed to the cart 22, and the cart is moved in the directions of arrows a and b. This amount of movement is detected by the rotary encoder 42. Also hole 1) and hole 13
The rotation amount of the circumference 12 corresponding to the intersection angle θ2 with the turning roller 25a is instructed, and the roller 25a is rotated. This amount of rotation is detected by the rotary encoder 43. The cart 22 moves a distance corresponding to the head h, and the turning roller 25a rotates the circumferential length 12, thereby causing the frame block 4 facing the cutter 32b to move.
The position is the drilling position of the hole 13. Therefore, it becomes possible to form the hole 13 with the cutter 32b at the above position. When the pipe supplied to the drilling device A is a straight-walled pipe 5 and a hole l3 is to be drilled in the straight-walled pipe 5, after detecting the reference position O,
Move the trolley 22 in the direction of arrow a to a height h. Karasumi block 4
By moving the straight wall tube 5 by a distance H(lI+1) on the circumference corresponding to the sum of the angles θ1 and θ2 by the turning roller 25a, the cutter 32b Place it opposite the drilling position of hole 13. becomes possible. Therefore, it is possible to form the hole 13 in the straight-walled tube 5 with the cutter 32b in said position.

Hole 1) and/or hole l for the tubes 4, 5 as described above.
3, move the trolley 22 on which the tube 4.5 is placed in the direction of arrow b.
direction and transferred to the outside of the drilling device A, and is discharged from the cart 22 by a transport device (not shown). In the above-mentioned embodiment, the drilling position information etc. can be input using either the code reader 34 or the keyboard 37, but this may also be configured so that it can be input only using the code reader 34. , or may be configured so that input can be made only using the keyboard 37.

Also, the tube 4 rotated by the turning roller 25a,
In order to detect the amount of rotation of the tube 5, for example, a roller is provided which is pressed against the surface of the tube 45 with a constant pressure and can rotate as the tubes 4 and 5 rotate, and a pulse transmitter such as a rotary encoder is attached to the roller. It is also possible to detect the amount of rotation of the tube 4.5 by attaching it and counting the pulses.
