Connected by members 4b and 4c and moved up and down through the base 2 with the center of the three cylindrical members 4a to 4a aligned with the center of the base 2 with respect to the base 2 It is comprised from the raising / lowering support | pillar 5 (equivalent to the raising / lowering member of Claim 1 and 2) mounted so that it was possible. The disk member 4b at the upper end of the lifting column 5 is mainly configured as a leg head 6 on which the laser marking device R or the like is placed, and the lifting column 5 is moved up and down by a drive unit in an electric lifting unit 8 described later. It is comprised as follows.

  The base 2 is composed of a seat part whose upper part is a flat surface and a housing part (not shown) assembled and fixed on the seat part.

The lifting column 5 is formed of three columnar members 4a to 4a arranged at equal intervals, and is installed so as to be movable up and down through the base 2, so that the shaft of the lifting column 5 as a whole is provided. Rotation around is prevented.

  The electric elevating unit 8 for elevating and lowering the elevating column 5 will be described. As shown in FIG. 10, the electric elevating unit 8 is assembled to the base 2, and the electric motor 9 and A drive unit 10 composed of a reduction gear mechanism (to be described later) that converts the rotation of the electric motor 9 into a linear motion to move the lifting column 5 up and down, and a remote control for remote operation (hereinafter abbreviated in this specification). A communication unit 11 that receives a remote control operation command from the means 24, and a calculation unit 12 that outputs an operation command for the electric motor 9 of the drive unit 10 based on communication information from the communication unit 11. Each is mainly composed of an electronic circuit or the like. The electric lifting unit 8 is configured to be removable from the base 2 as a whole, and when it is removed and assembled, the reduction gear mechanism in the drive unit and the lifting column 5 It is configured in consideration of the meshing relationship with the lifting rack 7.

  As shown in FIGS. 5 to 8, the drive unit 10 constituting the electric lifting unit 8 includes the drive motor 9 that can be rotated forward and backward mainly using a battery (not shown) as a power source and the lifting column 5. The planetary gear mechanism 13 or the like constituting a reduction gear mechanism for moving up and down is engaged with the drive gear 14 provided on the motor shaft of the electric motor 9 and a large-diameter gear 15. Between the large-diameter gear 15 and the opposed disk 16, the gear 15 and the small-diameter central gear 17 that is rotatably supported on the central axis, and the gear 15 and the disk 16.

The center gear 17 is rotated, and the planetary gear 18 meshed with the center gear 17 revolves around the center gear 17 and transmits the reduced rotation to the pinion 19. As a result, the entire lifting column 5 is automatically moved up and down via the lifting rack in mesh with the pinion 19. In the case of the handle 23 for manual operation, as in the case of the drive motor 9, the lifting column 5 is raised when rotated in the forward rotation direction (for example, the right direction), and the reverse direction ( For example, it is set and controlled so that the lifting column 5 is lowered when it is rotated in the left direction. Further, in the case of automatic raising / lowering in which the rotation from the drive motor 9 is transmitted to the lifting rack via the pinion 19, the second speed is reduced by the reduction ratio of the planetary gear group 13, the first and second worms 20, 21. The worm 21 and the manual operation handle 23 are configured not to be transmitted, and conversely, when the second worm 21 is rotated via the manual operation handle 23, the second worm 21 and the first operation handle In the case of manual lifting that is transmitted to the pinion 19 and the lifting rack via meshing with the worm 20, the load received from the electric motor 9 is not exerted on the manual operation handle 23 by the reduction ratio of the planetary gear group 13. It is configured.

Further, the communication unit 11 constituting the electric lift unit 8 receives a remote control operation command by, for example, infrared communication or radio wave communication from the remote control means 24 for remote operation, and transmits the communication information to the electric lift unit. The electronic circuit is configured to transmit to the arithmetic unit 12 that constitutes 8, and the receiving unit 11 a in the communication unit 11 is mounted on the base 2.
The remote control operation command from the remote control means 24 for remote operation is transmitted from the transmitter 25 to the receiver 11a of the communication unit 11 constituting the electric lift unit 8 as infrared communication or radio wave communication. .

  In this embodiment, the leg head 6 of the lifting column 6 related to the drive unit 10 in the electric lifting unit 8 is, for example, surveyed by a laser marking device R for irradiating laser light in the horizontal direction. In the operation block diagram of the electric lift unit 8 and the remote control means 24 shown in FIG.

  Further, in addition to the remote control means 24 for remote operation, the position of the laser beam irradiated in the horizontal direction from the laser marking device R shown in FIG. The remote control means 27 which transmits to the receiving part 11a of the communication part 11 which comprises the electric raising / lowering unit part 8 can also be used.

A light receiving portion (surface) 28, a display portion 29 for displaying whether the received laser light is a reference position (center position), an upper position from the reference position, or a lower position from the reference, and the received laser light is a reference. The position of the laser beam irradiated horizontally from the two transmitters 30a and 30b that transmit the position information that is higher than the position or the position information that is the lower position as infrared communication or radio wave communication, respectively. As an example of a remote control operation unit that operates in advance to a predetermined position, for example, a lift operation button 31 that operates the drive unit 9 to drive and stop the drive motor 9 upward. Further, a descent operation button 31b for operating descent driving and stopping of the drive motor 9 is formed, and further, the remote control means 27 with a light receiving device for remote operation includes the above-mentioned operation buttons as shown in FIG. A remote control operation unit 32a corresponding to the operation information of the buttons 31a and 31b, a communication unit 32b that communicates an operation instruction of the remote control operation unit 32a using infrared communication or radio wave communication as a communication means, and a horizontal direction from the laser marker R A light receiving unit 28 that receives the laser light applied to the light source, and calculates and compares the detected position with a reference position (the center position of the display unit 29) based on the detected position information from the light receiving unit 28 The calculation unit 32c for inputting the position information to the communication unit 32b is constituted by each electronic circuit means, and the position information from the communication unit 32b and the remote controller Work instructions is configured to transmit to the receiving portion 11a of the communication unit 11 constituting the transmission unit 30a, respectively, from 30b electric elevation unit part 8 as the infrared communication or radio communication.

  The automatic elevating tripod 1 according to the present embodiment is configured as described above, and is used by placing various arbitrary surveying instruments on the leg head 6. When adjusting the height position of the installed surveying instrument, that is, the height of the lifting column 5, as shown in the operation block diagram of FIG. 10 and the flowchart of FIG. The operation is started by pressing the ascending operation button 24a or the descending operation button 24b on the remote controller 24 and instructing the ascending (or descending) operation. In the following description, the case of ascent will be mainly described.

  First, the operation is started by pressing the operation button 24a for raising (or the operation button 24b for lowering) and transmitting the ascending (or lowering) instruction from the communication unit 11 of the electric elevator unit 8. In this case, the control speed is set to gradually increase to the maximum speed when the operation button 24a for raising (or the operation button 24b for lowering) is continuously pressed.

The communication information of the pressing operation button 24a (or the descending operation button 24b) received by the communication unit 11 is transmitted to the calculation unit and processed by the calculation unit 12.
That is, when the operation button 24a for raising (or the operation button 24b for lowering) is pressed and the operation is continued, the operation button 24a for raising (or the operation button 24b for lowering) is continuously pressed. Proceed to the “Speed control instruction” step. (Step 1)

  Next, in the case of “with speed control instruction”, the process proceeds to the step “There is a manual operation in the drive unit 10 in the electric lift unit 8” through the state where the ascending (or descending) speed is accelerated (or decelerated). . (Step 2)

  Further, when the drive unit 10 in the electric lifting unit 8 is not manually operated, the next step is to determine whether or not “the drive motor in the electric lifting unit is operating to the upper (or lowering) limit”. Proceed to (Step 3)

  Then, when the drive motor in the electric lift unit 8 is not operated to the ascending (or descending) limit, the remote controller operation (the pressing operation of the operation buttons 24a and 24b) is canceled, so that the electric lift unit 8 The drive of the drive motor 9 is stopped, the automatic lifting / lowering (lowering) of the lifting column 5 using the drive motor 9 as a drive source is stopped, and this series of operations is completed.

  Further, in the above-described step 2, when manual operation is performed in the drive unit 10 in the electric lifting unit 8, the manual operation, that is, the handle operation for manual operation is given priority, and the lifting column is determined by the rotation operation of the handle. 5 is raised (or lowered), the handle operation for manual operation is released, and the operation button 24a for raising (or the operation button 24b for lowering) is continuously pressed. The operation proceeds to the step of whether or not the operation instruction from the remote control is “continuing” (step 4). If the operation instruction from the remote control is continuing, the process returns to step 1, and the operation instruction from the remote control is When it is released, it is processed as a manual stop.

  In step 3, when the drive motor 9 in the electric lift unit 8 is operated to the ascending (or descending) limit, the limit alarm operation corresponding to the operation buttons 24c and 24d for the ascending limit and the descending limit is performed. The operation proceeds to the step of whether or not “the operation instruction from the remote control is continuing” (step 5), and when the operation instruction from the remote control is released, the remote control operation (the pressing operation of the operation buttons 24a and 24b) ) Is stopped, the drive of the drive motor 9 is stopped in the electric lift unit 8, and the automatic lift (descent) of the lift column 5 using the drive motor 9 as a drive source is stopped, and the operation instruction from the remote control is continuing. In the case, the process proceeds to the step of whether or not the “motion instruction direction is reversed”, such as descent if it is an ascent limit (or rise if it is a descent limit). Step 6), if the operation specified direction is not reversed, the process returns to step 5, and if the operation instruction direction is inverted back to the step 1.

  As described above, the drive motor 9 of the drive unit 10 is operated via the communication unit 11 and the calculation unit 12 in the electric lift unit 8 by operating the operation button 24a for raising or the operation button 24b for lowering on the remote control means 24. And the lifting column 5 is automatically moved up and down via the planetary gear mechanism 13 and the like operated by the drive motor 9.

Next, the laser beam irradiated in the horizontal direction from the laser marking device R tracks the position of the light receiving portion 28 (light receiving surface 28a) of the light receiving device of the remote control means 27, and receives the light receiving portion 28 (light receiving surface 28a) of the light receiving device. To the leg head 6 of the automatic elevating tripod 1 using the remote control means 27 that transmits the position of the received laser beam as position information to the receiving unit 11a of the communication unit 11 constituting the electric elevating unit 8. Then, the height of the lifting column 5 is adjusted by the operation of the photoreceiver set at the laser beam height position, that is, the laser beam irradiation height position to be obtained in advance. The case where it does is demonstrated.
As shown in the operation block diagram of FIG. 13 and the flowchart of FIG. 14, the power supply in the electric lifting unit 8 is turned on, the laser beam is emitted from the laser marking device R, and the remote control means includes a light receiver. 27 is installed at an arbitrary height, and the ascending operation button 31a (or the descending operation button 31b) on the remote control means 27 is pressed to transmit automatic ascending / descending operation instruction information from the transmitting unit 32b to the electric elevating / lowering unit unit 8. The up and down motion is started.

  First, the laser beam irradiated in the horizontal direction from the laser marking device R is incident on the light receiving surface 28a of the light receiving unit 28 of the remote control means 27, that is, “the laser line is incident on the light receiving surface of the light receiving unit”. Proceeding (step 1), when it is detected that the laser line is incident on the light receiving surface 28a of the light receiving unit 28, the laser line incident information is transmitted to the electric lift unit 8 by the transmitting unit 32b of the remote control means 27. Then, the process proceeds to a step of determining whether or not the detected position of light reception is the reference position of the light receiving section 28, that is, “the light reception detection is the center position of the light receiving section”. (Step 2)

If the light-receiving detection of the laser line is not at the center position of the light-receiving unit 28, the next step is performed at the decelerated operation speed with respect to the drive unit 10 in the electric lifting unit 8, that is, “laser at the reference center of the light-receiving unit”. Proceed to the step of whether or not the line is received. (Step 3)
When this laser line is received at the reference position (center position) of the light receiving unit 28, the center position light receiving information is transmitted from the transmitting unit 32b to the electric lift unit 8, and the drive of the drive motor 9 of the drive unit 10 is stopped. Then, the lifting / lowering operation with respect to the lifting / lowering support column 5 is stopped, and the lifting / lowering operation of automatic tracking by remote operation is completed.

  In step 1, when it is not detected that the laser line is incident on the light receiving surface 28a of the light receiving unit 28, it is determined whether or not the operation has been performed up to the lower limit of the drive unit 10 of the electric lifting unit 8. (Step 4), if the operation is not performed up to the elevating limit of the electric elevating unit 8, the process returns to step 1; The process proceeds to step 5 indicating whether or not “limit detection has been performed any number of times” or not. In step 5, if limit detection is not performed any number of times, the process returns to step 1. If limit detection is performed at an arbitrary number of times or more in step 5, it is processed as “automatic tracking impossible error stop” to be described later.

  In the step 2, if “the light detection is the center position of the light receiving portion”, the position information of the laser line after passing through the center position is transmitted, and the up / down inversion operation is decelerated after the step 2. Return to step 3 at the operation speed.

  If the laser line is not received at the reference position (center position) of the light receiving unit 28 in step 3, it is determined in step 6 whether or not the “laser line position information has been lost”. If the instruction to decelerate the operation speed is released and the process returns to step 4 and is not interrupted, the process proceeds to step 7 to determine whether or not the position information of the laser line transmitted by the light receiving unit 28 is upside down. If “the position information of the laser line transmitted by the light receiving unit 28 is not upside down”, the process returns to the above step 3. If the “position information of the laser line transmitted by the light receiving unit 28 is upside down”, the following “ The process proceeds to step 8 for determining whether or not the inversion of the position information has been repeated for an arbitrary number of times. Returning to-up 3, when the inversion of position information repeated more than any times is to be treated as "automatic tracking unrecoverable error stop".

  As described above, the laser beam emitted from the laser marking device R in the horizontal direction is received by the remote controller 27 provided with the light receiving unit 28 in the light receiving device in the state where the position is tracked and received. The position of the laser beam is transmitted as position information to the communication unit 11 constituting the electric lifting unit 8, and the driving motor 9 of the driving unit 10 is driven to operate the planetary gear mechanism 13 and the like operated by the driving motor 9. The up-and-down support column 5 is automatically moved up and down, that is, the remote control means 27 with a light receiver is set at the irradiation height position of the laser light to be obtained in advance, and the laser light is passed through the light-receiving portion 28 of the light receiver at that position. In the remote control means 27 which is irradiated in the tracked state, automatically lifts and lowers the lifting column 5 based on this light receiving position operation, and is set to the laser beam irradiation height position to be obtained in advance. So as to correspond position to the light receiving portion 28 of the optical device, the height position of the laser Bokude device is to automatically set remotely state.

Further, as shown in FIG. 15, a light receiver 40 mainly configured as a light receiver for receiving laser light in the above-described remote control means 27 and a remote control means 24 that performs the above-described remote control function are provided. It is also possible to use it by connecting by means capable of transmitting information (in the figure, the case of the cord 31 for electrically transmitting information is shown). As described above, the information can be transmitted by any means such as infrared communication, radio wave communication, and direct connection between both terminals.
In this case, the remote control means 27 in which the function of the above-described light receiver (light receiving unit 28) is incorporated is configured as a single light receiver 40 that receives laser light, and the laser light is received by the light receiver 40. The position information thus transmitted is transmitted from the remote control means 24 to the electric lifting / lowering unit section 8, and the drive (lifting / lowering) operation of the drive motor 9 in the driving section 10 of the electric lifting / lowering unit section 8 is described with reference to FIG. Since the operation is the same as that shown in the flowchart of FIG.

  In the description of each embodiment described above, the case where the electric lifting unit 8 is attached to the tripod 1 has been described. However, instead of the tripod 1, for example, devices such as clamp members clamped to columns, beams, or the like Combining with a mounting member, a surveying instrument such as a laser marking device R is assembled to the lifting member of the clamp member, and the lifting and lowering operation of the lifting member is remotely controlled as in the above-described embodiment, thereby the laser marking device. The present invention can be easily applied (implemented) to an aspect in which the height of a surveying instrument such as R is automatically set.

Further, in the above-described embodiment, the case where the laser marking device R is attached to the tripod 1 side has been described. When the laser marking device R is installed at a different location (place) and used, the height of the horizontal laser beam emitted from the laser marking device R is determined by the light receiving device. The light receiver 40 and the remote control means 27 with the light receiver receive light by the light receiver, and the light receiver 40 and the remote control means 27 with the light receiver are moved up and down by the lifting column 5 based on the light receiving position. That is, the operation of tracking the laser beam from the laser marking device R is performed, and thereby the horizontal irradiation height of the laser beam from the laser marking device R can be automatically detected.
