However, even if the pressurizing unit is configured to be rotatable in the state where the captive bolt is fastened, the method of measuring the underground facilities using the conventional fast fixer can not help but the rotational force of the bolt can not be transmitted. Therefore, when the excessive force is applied, The surface of the substrate is damaged.

In the conventional method of measuring the underground facilities, the horizontal stiffener 1 is placed on the upper surface of the underground G so as to maintain its horizontal position. Therefore, when the underground G is not flat or inclined, (2) is also connected to the horizontal stiffener (1) at 90 degrees, so that the vertical accuracy can not be maintained and the accuracy of measurement is reduced.

Furthermore, when vibrations or shocks occur in the vicinity of a star in the process of underground facilities surveying, there is a problem that a measurement error occurs due to shaking of a staff during a reading process of a conventional underground facility.

FIG. 2 is a view showing an overall configuration of a starter device for underground facilities according to an embodiment of the present invention. Referring to FIG.

As shown in the figure, the starter apparatus for measuring underground facilities according to the present invention includes a support plate 100 having a plurality of horizontal adjustment units 110 mounted on both sides thereof, an installation unit 200 coupled to one side of the support plate, A posture aligning part 300 coupled to an end of the installation part, a vertical post 400 coupled to the posture aligning part so as to be vertically disposed, a horizontal star pulled from the front of the support plate and orthogonal to the vertical post, And a fixing device 600 for fixing the vertical stapler and the horizontal stapler in a cross shape.

The support plate 100 is a base on which the respective components according to the present invention are installed. A control unit 102 is incorporated in the support plate 100 and a switch 103 to which a button 104 is attached is coupled to one side of the support plate 100.

The control unit 102 electrically connects the switch 103 to a configuration of a horizontal adjustment motor 112, a length adjustment motor 224, a stop cylinder 350, and an electromagnetic unit 610, which will be described later. Such an electrical connection structure is a conventional technology and is not a core constitution of the present invention, so a detailed description thereof will be omitted. In addition, though not shown, a battery or the like is installed at one side of the support plate 100, so that the components can be driven through the control unit.

In the illustrated embodiment, the support plate 100 is formed in a rectangular plate shape, but is not limited thereto, and may be modified into various shapes according to the convenience of the user. When the surveying operation is carried out, it is preferable that the support plate 100 is positioned such that the front surface thereof can be aligned with the reference point of the ground surface.

The switch 103 may be equipped with various buttons 104 for operating a horizontal adjustment motor 112, a length adjustment motor 224, a stop cylinder 350, and an electromagnetic part 610, which will be described later. The user can easily operate each configuration of the present invention simply by pressing the button 104 of the switch 103. [

The installation part 200 comprises a upright tube 210 vertically installed on the upper part of the support plate 100 and a connection tube 220 connected to the upright tube at right angles with the upright tube. The connection pipe 220 is connected to the first connection pipe 221, one side of which is fixed to the upright pipe 210 and is hollow, and the other end of the first connection pipe 221, The second connection pipe 222 can be divided into two. That is, the connection pipe 220 can be expanded or contracted back and forth.

A horizontal rotation part 101 to which a lower end of the upright pipe 210 is connected may be mounted on one side of the support plate 100. The horizontal rotation part 101 is inserted into a rotation groove formed in the support plate 100 so that the upright tube 210 can rotate in the axial direction. The horizontal rotation unit 101 may be implemented as a rotatable drive motor or the like, and such a drive motor may be electrically connected to the control unit 102 and operated on the switch 103.

Since the horizontal rotation unit 101 can horizontally rotate the upright pipe 210, the connection pipe 220, the posture aligning unit 300 and the vertical stiffener 400 to be horizontally rotated at a time, So that it is possible to accurately set the workpiece 400 at a desired position, and to perform a surveying operation at an optimum position in consideration of a work environment such as wind.

Each of the upright tube 210 and the connecting tube 220 may be formed in a column shape having a rectangular cross section, and the inside thereof may be formed in an empty shape so that various parts such as electric wires can be inserted.

The posture aligning unit 300 is installed between the mounting unit 200 and the vertical stapler 400 so that the vertical stapler 400 can always maintain a vertical position and can be protected from external impacts. In addition, the posture aligning unit 300 allows the vertical post 400 to be pivoted in place, thereby enabling a more accurate surveying operation. Since the vertical stud 400 is rotatable about its axis, the front surface of the vertical stud 400 can be closely attached to the rear surface of the horizontal stud 500.

As shown in Fig. 1, the conventional horizontal stiffener 1 is placed on the ground to be horizontal, and the vertical stiffener 2 is perpendicularly connected to the horizontal stiffener 1 in a vertical direction. Since the posture aligning unit 300 aligns at the top of the vertical post 400, the posture aligning unit 300 can easily maintain its vertical position by using its own weight regardless of posture of the horizontal post 500 according to the state of the ground There are advantages.

In addition, the posture aligning part 300 according to the present invention can always make the vertical post 400 always vertical regardless of the state of other components such as the support plate 100 and the installation part 200, There is an advantage that the work can be secured.

In the illustrated embodiment, the vertical stapler 400 is shown as a single bar, but this is for convenience of expression, and it will be appreciated by those skilled in the art that the vertical stapler 400 is multi-tiered and can be stretched up and down.

The transverse stiffener 500 also has a multi-stage structure and can be stretched back and forth. The horizontal stiffener 500 may be drawn out from the lead portion 130 formed in the support plate 100 in a longitudinal direction (forward and backward direction) and may be installed on the front surface of the support plate 100 in the width direction And can move in the width direction along the rail 140. [

That is, the horizontal stapler 500 can be expanded and contracted in the front-rear direction, and can be moved in the lateral direction at the same time. Since the horizontal stapler 500 can be moved in the left and right direction, the rear surface of the horizontal stapler 500 can be fixed to the front surface of the vertical stapler 400 in a cross shape.

The front surface of the horizontal stapler 500 and the vertical stapler 400 are scored along the longitudinal direction. The scale of the horizontal staple 500 is used to measure the distance from the reference point to the underground facility, and the scale of the vertical staple 400 is used to measure the depth of the underground facility.

The fixing device 600 is configured to fix the vertical stiffener 400 and the horizontal stiffener 500 in a cross shape and is coupled to the front center of the vertical stiffener 400 along the longitudinal direction An electromagnetic portion 610 and a connecting portion 620 described later.

As described above, since the vertical stapler 400 and the horizontal stapler 500 are fixed through the electromagnetic portion 610 instead of being physically engaged, the effect of completely preventing the vertical stapler 400 from being damaged is obtained have.

Hereinafter, specific details of each configuration of the present invention will be described.

FIG. 3 is a view showing an exploded view of each component of the horizontal adjustment device according to an embodiment of the present invention, and FIG. 4 is a view illustrating a horizontal sensor according to an embodiment of the present invention.

The horizontal adjustment device 110 includes an adjustment body 111 protruding from the side of the support plate 100, a horizontal adjustment motor 112 coupled to the upper surface of the adjustment body, And a height adjusting portion 115 coupled to the through-hole.

Since the height adjuster 115 can be moved up and down, the height of the horizontal adjuster 110 can be adjusted relative to the ground, and thus the height of the support plate 100 can be adjusted, It can be leveled regardless of the state of the ground.

A first adjusting gear 113 and a second adjusting gear 114 are installed inside the adjusting body 111. The first adjustment gear 113 is coupled to the rotation axis of the horizontal adjustment motor 112 and is rotated together with the rotation of the horizontal adjustment motor 112. A gear tooth is formed on the outer circumferential surface of the first adjusting gear 113 and a gear tooth that is engaged with the gear tooth of the first adjusting gear 113 is formed on the outer circumferential surface of the second adjusting gear 114. In other words, when the leveling motor 112 is driven, the first adjusting gear 113 rotates together, and the second adjusting gear 114 rotates according to the rotational force transmitted from the first adjusting gear 113.

The second adjusting gear 114 is formed in a ring shape like a donut. The outer circumferential surface of the second adjusting gear 114 is engaged with the first adjusting gear 113 and the inner circumferential surface of the second adjusting gear 114 is formed with the thread 114a.

The height adjusting portion 115 is inserted into the inner circumferential surface of the second adjusting gear 114 and moves up and down. A thread 115a is formed on the outer circumferential surface of the height adjusting portion 115 so as to be engaged with the thread 114a of the second adjusting gear 114. [

That is, as the second adjusting gear 114 rotates, the thread 115a of the height adjusting portion 115 can be rotated by engaging with the thread 114a of the second adjusting gear 114. At this time, a slider 116 is coupled to the upper surface of the adjustment body 111, and the slider 116 is inserted into a slide groove 115b formed in the side of the height adjustment part 115 along the longitudinal direction.

The slider 116 serves to support the height adjusting portion 115 so that the height adjusting portion 115 can be moved up and down without being rotated by the second adjusting gear 114. As the height adjuster 115 moves up and down without rotating, the distance of the horizontal adjuster 110 relative to the ground varies.

When the height adjusting part 115 is lowered, the horizontal adjusting device 110 and the supporting plate 100 are relatively moved away from the ground surface. As the height adjusting part 115 rises The horizontal adjustment device 110 and the support plate 100 have the effect of relatively lowering the distance from the ground.

In the illustrated embodiment, the horizontal adjustment device 110 is installed on the supporting plate 100 on two sides of the supporting plate 100. However, the present invention is not limited thereto. And can be installed in various ways.

A horizontal sensor 120 is coupled to one side of the support plate 100 to transmit the horizontal measurement value of the support plate 100 to the control unit 102. The control unit 102 is electrically connected to the horizontal adjustment motor 112 to raise or lower the height adjustment unit 115.

4, the horizontal sensor 120 includes a sensor main body 121 coupled to one side of the support plate 100 and having a slot 121a formed along the longitudinal direction thereof, a sensor main body 121 inserted into the slot 121a, And a sensing unit 123 coupled to both ends of the sensor 121 and the sensor 121 for sensing the position of the sensor 122.

The sensor aperture 122 may have a spherical shape. However, the sensor aperture 122 may be formed in a pointed shape with front and rear faces so as to easily move in the slot 121a as in the illustrated embodiment, and the bottom face is preferably formed in a flat shape Do. This is because, in the case of the spherical shape, it moves too often in the slot depending on whether the supporting plate is horizontal or not.

The sensor unit 122 may be made of a permanent magnet, and the sensing unit 123 may utilize a switch terminal having a terminal made of a magnetic material corresponding to the permanent magnet. Since the sensing unit 123 is coupled to both ends of the slot 121a, it is possible to determine whether the support plate 100 is tilted forward or backward.

Although the horizontal sensor 120 is shown as being disposed in the front-rear direction of the support plate 100 in the illustrated embodiment, the horizontal sensor 120 disposed in the left-right direction of the support plate 100 And a plurality of the support plates 100 may be provided.

When it is confirmed that the support plate 100 is tilted forward by the horizontal sensor 120, the horizontal adjustment device 110 disposed on the front side of the support plate 100 rises to align the support plate 100 horizontally, The horizontal adjustment device 110 disposed on the rear side of the support plate 100 rises to align the support plate 100 horizontally.

Similarly, when it is confirmed that the support plate 100 is tilted to the left by the horizontal sensor 120, the horizontal adjustment device 110 disposed on the left side of the support plate 100 rises to horizontally align the support plate 100, The horizontal adjustment device 110 disposed on the right side of the support plate 100 rises to align the support plate 100 horizontally.

As described above, according to the present invention, the support plate 100 can be horizontally aligned regardless of the tilting or the state of the ground using the horizontal adjustment device 110, and the horizontal staple 500 drawn out from the support plate 100 is also horizontally The measurement accuracy can be remarkably improved.

FIG. 5 is a longitudinal sectional view showing a connector according to an embodiment of the present invention. FIG.

As described above, the installation part 200 includes the upright pipe 210 and the connection pipe 220, and the connection pipe 220 is connected to the first connection pipe 221, And a tube 222.

The inside of the first connection pipe 221 and the second connection pipe 222 may be formed in an empty shape and the second connection pipe 222 may be separated from the first connection pipe 221 A stopper or the like may be further installed so as not to escape.

An elastic member 223 is engaged between the rear end front surface of the first connection pipe 221 and the rear end rear surface of the second connection pipe 222 to elastically support the second connection pipe 222 forward. That is, since the rear end of the first connection pipe 221 is fixed to the upright pipe 210, the second connection pipe 222 always tries to move in the extending direction.

A length adjusting motor 224 is provided on the front end of the rear end of the second connecting pipe 222 and a length adjusting wire 225 connected to the rear end front surface of the first connecting pipe 221 is connected to the length adjusting motor 224. [ Is wound. The length adjusting motor 224 may be electrically connected to the control unit 102 and operated by the switch 103.

When the length adjusting wire 225 is loosened by the length adjusting motor 224, the elastic force of the elastic member 223 moves the second connecting pipe 222 forward to increase the total length of the connecting pipe 220, When the length adjusting wire 225 is wound by the length adjusting motor 224, the elastic force of the elastic member 223 is overcome and the second connecting pipe 222 moves backward to reduce the overall length of the connecting pipe 220.

At this time, since the vertical stiffener 400 is connected to the connection pipe 220 by the posture aligning unit 300, the vertical post 400 is moved to the location where the underground facility is located in the excavation hole corresponding to the extension or contraction of the connection pipe 220 .

Therefore, the user can easily adjust the position of the vertical stapler 400 only by driving the length adjusting motor 224 electrically connected to the control unit 102 by pressing the button 104 of the switch 103, It is effective to prevent the accident of the spinal cord caused by the fall.

6 is a cross-sectional view of a posture aligning part according to an embodiment of the present invention.

As shown in the figure, the posture aligning unit 300 includes a case 310 coupled to an end of the second connection pipe 222 and opening downward. The case 310 is formed in a 'C' shape in its cross section as a whole, and includes an inner plate 311 and an outer plate 312. The inner plate 311 and the outer plate 312 are spaced from each other to form an oil space 313 so that the oil 314 can be injected therebetween.

The outer plate 312 is provided with an injection port 360 through which an oil can be injected into the oil space 313. Specifically, the injection port 360 includes an injection body 361 penetratingly connected to the outer plate 312, an injection plug 362 accommodated in the injection body, and an injection spring 363). Since the small holes are formed at both ends of the injection body 361, the external oil 314 can be injected into the oil space 313 of the case 310.

A base 320 is coupled to an upper portion of the inner plate 311 of the case 310. A hemispherical pivot hole 321 is formed at the lower end of the base 320 so that the spherical head 330 accommodated therein can be rotated forward, backward, leftward, and rightward. The head 330 is also rotatable in the axial direction of the vertical stud 400 in place.

In other words, both the case 310 and the base 320 are coupled with the second connection pipe 222 and are inclined to the same posture. Since the spherical head 330 can freely rotate within the pivot hole 321, The staff 400 can always maintain a vertical state due to its own weight.

At the side of the vertical stud 400 coupled to the lower part of the head 330, the buffer part 340 is elongated outwardly. The buffer part 340 moves to the inside of the oil space 313 of the case 310 and a partition wall 341 is formed at the end of the buffer part 340 in a direction transverse to the oil space 313 .

Since the buffer part 340 is made of an elastic material, it can be bent upward or downward according to the posture of the vertical stiffener 400. A small through hole 342 is formed in the partition wall 341, Is passed.

Although not shown, a portion (the end of the case) where the buffer portion 340 enters the case 310 and a portion where the injection port 360 is coupled to the case 310 So that the oil 314 in the case 310 is not leaked out.

The buffer part 340 may be formed as a thin rod having elasticity, and the partition wall 341 may be formed in a plate shape. The buffer part 340 and the partition wall 341 may be formed of the same material, but the present invention is not limited thereto.

Since the partition wall 341 coupled to the end of the buffer part 340 is moved between the oil 314 injected into the oil space 313, the external shock generated around the vertical part 400 is reduced, Can be protected.

In addition, a stop cylinder 350 is inserted into the base 320 to selectively stop the head 330 temporarily inserted into a plurality of stop grooves 331 formed in the upper portion of the head 330. The stop cylinder 350 may be driven by the operation of the switch 103 electrically connected to the control unit 102 and coupled to the handle.

After the vertical stud 400 is vertically aligned with the measurement point where the underground facility is installed, the stop cylinder 350 may enter the stop groove 331 to temporarily fix the head 330.

FIG. 7 is a diagram illustrating a perspective view of a street star according to an embodiment of the present invention.

As shown in the figure, the transverse stiffener 500 is constructed in multiple stages and is expandable and contractible. The lateral stiffener 500 is used to measure the distance from the reference point to the underground facility.

The transverse stiffener 500 may be drawn out from the extended portion 130 formed in the longitudinal direction (longitudinal direction) of the support plate 100. That is, the horizontal stapler 500 is housed in the take-out unit 130 and can be taken out only when performing a surveying operation.

A rail 140 is installed on the front surface of the support plate 100 in the width direction (left and right direction). The rail 140 is formed in a 'A' shape in cross section so that the horizontal stapler 500 can be moved in the width direction.

The user manipulates the vertical stapler 400 to be positioned on the underground facility of the excavation hole by using the horizontal rotation unit 101 and the connection pipe 220 and then moves the horizontal stapler 500 in the left- (400) so that the horizontal stiffener (500) is placed on the underground facility.

A guide 510 is coupled to an end of the transverse stiffener 500 such that the transverse stiffener 500 can be moved in the transverse direction. The guide unit 510 includes a pair of guide bodies 512 accommodated in the guide holes 511 or exposed through the guide holes 511 and selectively received in the rails 140 and installed in the guide holes 511 And a guide spring 513 for providing an elastic force to the guide body 512.

The guide body 512 is accommodated in the guide hole 511 when the horizontal stapler 500 is accommodated in the drawer 130 and the horizontal stapler 500 is drawn out from the drawer 130 And protrudes from the inside of the guide hole 511 and is accommodated in the rail 140.

At this time, a tapered end portion 512a forming an inclined surface is formed on one side of the guide body 512 (rear side in the illustrated embodiment).

Since the upper end of the vertical stud 400 is fixed by the stop cylinder 350 and the lower portion is fixed by the fixing device 600, the vertical stud 400 can be stably supported during the measurement process, (500) is also stably supported since one end is fixed to the rail (140) and the other end is fixed by the fixing device (600).

Since the buffer part 340 is coupled to the upper portion of the vertical stud 400 and the partition wall 341 is coupled to the end of the buffer part 340 to be movable in the oil 314, The staff 400 and the lateral staff 500 are protected.

When the vertical stapler 400 and the horizontal stapler 500 are fixed in a cross shape, the user reads the scale of the horizontal stapler 500 to measure the separation distance of the underground facility, The depth of the underground facility can be measured by reading the scale of.

As a result, according to the present invention, since the support plate 100 can be leveled by the leveling device 110 regardless of the state of the ground, the horizontal staple 500 taken out from the support plate 100 can be automatically leveled Since the vertical post 400 can be vertically arranged automatically by the posture aligning unit 300, the accuracy of measurement can be remarkably improved.

In addition, since the connecting pipe 220 of the installation part 200 is configured to extend and retract forward and backward, and a staff can be installed at a desired point without entering the excavation hole, the safety accident of the spinal cord caused by the earth- .

In addition, since the shock absorber 340 can protect the staff from external shocks or vibrations occurring in the vicinity of the staff, the present invention can significantly reduce the measurement error.

Further, since the horizontal stapler 500 and the vertical stapler 400 can be fixed in a cross shape using the electromagnetic portion 610 and the connecting portion 620, the present invention can solve the problem of damaging the vertical stapler 400 There is an advantage that it can be prevented from origin.
