[0001] The utility model relates to the technical field of laser measurement, in particular to a double three-dimensional adjustment mechanism for laser measurement. Background Technique

[0002] Laser ranging uses a laser as a light source for ranging. According to the working mode of the laser, it is divided into continuous lasers and pulsed lasers. Gas lasers such as helium-neon, argon-ion, and krypton-cadmium work in a continuous output state and are used for phase-type laser ranging. The double three-dimensional adjustment mechanism is a device that adjusts the angle and position of the laser measuring instrument when there are deviations in the angle and position of the laser measuring instrument, improving the measurement accuracy.

[0003] The double three-dimensional adjustment mechanism for laser measurement with the application number 202320179877.6 includes a frame. A hydraulic cylinder is fixedly connected to the bottom of the inner cavity of the frame. The output shaft of the hydraulic cylinder is fixedly connected to a bottom plate that is slidably connected to the inner cavity of the frame. A moving component is arranged on the top of the bottom plate. A support plate is fixedly connected to the top of the moving component. A plurality of brackets are fixedly connected to the top of the support plate. The top of the plurality of brackets as a whole is hinged to a mounting plate, and an adjustment component is arranged between the mounting plate and the support plate. For this double three-dimensional adjustment mechanism for laser measurement, the height of the laser rangefinder can be adjusted through the hydraulic cylinder, the left and right movement of the laser rangefinder can be driven through the electric push rod, the front and back movement of the laser rangefinder can be driven through the moving component, thereby changing the three-dimensional position of the laser rangefinder. Through the setting of the adjustment component, the angle of the laser rangefinder can be adjusted, achieving the purpose of facilitating the adjustment of the double three-dimensional adjustment mechanism for laser measurement.

[0004] For this technical solution, the horizontal adjustment drives the measuring instrument to move horizontally through a motor screw rod, but the adjustment range is limited. The maximum adjustment position depends on the size of the adjustment mechanism. If there is a large horizontal adjustment requirement, the size of the adjustment mechanism will also be large. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a double three-dimensional adjustment mechanism for laser measurement to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A double three-dimensional adjustment mechanism for laser measurement includes a base. A guide frame is connected inside the base, and a lead screw passes through the top of the guide frame. An adjustment frame is connected between the lead screw and the guide frame, and a wheel frame is sleeved outside the adjustment frame. A roller is connected inside the wheel frame. A positioning rod is connected to one side of the bottom of the wheel frame, and a positioning groove is opened on the inner wall of the base.

[0007] By adopting the above technical solution, when horizontal adjustment is required, the wheel frame is rotated 90 degrees to make the roller face the X-axis or Z-axis, and then the screw rod is rotated. After the screw rod rotates, it cooperates with the guide frame to guide the adjustment frame to drive the wheel frame downward. After the wheel frame moves downward, the roller contacts the ground, and at the same time, the positioning rod enters the positioning groove to ensure that the wheel frame is perpendicular to the X-axis and the Z-axis. Then, the mechanism can be pushed to move in the X-axis direction or the Z-axis direction. After the adjustment is completed, the screw rod is reversed, so that the wheel frame drives the roller to move upward. At this time, the base contacts the ground to generate friction to avoid displacement of the mechanism, and at the same time, the positioning rod is moved out of the positioning groove to adjust to other directions.

[0008] Furthermore, the adjusting frame is threadedly connected to the lead screw, and the adjusting frame is slidably connected to the guide frame.

[0009] By adopting the above technical solution, the staff rotates the screw rod, and after the screw rod rotates, it cooperates with the guide frame to guide the adjustment frame to drive the wheel frame to move downward. After the wheel frame moves downward, the roller contacts the ground and lifts the base.

[0010] Furthermore, the cross section of the adjusting frame is in an I-shape, and the wheel frame is rotatably connected to the adjusting frame.

[0011] By adopting the above technical solution, when horizontal adjustment is required, the staff rotates the wheel frame 90 degrees to make the roller face the X-axis or Z-axis, so that the subsequent staff can push the mechanism to move along the X-axis direction or the Z-axis direction.

[0012] Furthermore, four rollers are provided, and the four rollers are symmetrically distributed.

[0013] By adopting the above technical solution, after the wheel frame moves down, the roller contacts the ground, and then the staff can push the mechanism to move along the X-axis direction or the Z-axis direction.

[0014] Furthermore, four positioning rods and four positioning grooves are provided, and the four positioning rods and the four positioning grooves are distributed in a ring array.

[0015] By adopting the above technical solution, the positioning rod enters the positioning groove after the wheel frame moves downward, ensuring that the wheel frame is perpendicular to the X-axis and the Z-axis.

[0016] Furthermore, a hand wheel is fixed on the top end of the screw rod.

[0017] By adopting the above technical solution, the setting of the hand wheel makes it convenient for the staff to rotate the screw rod, thereby facilitating the adjustment frame to move upward or downward.

[0018] Furthermore, an electric turntable is installed on the top of the base, and the output end of the electric turntable is connected to a bracket, a motor is installed on one side of the bracket, and the output end of the motor is connected to a mounting seat, and a laser measuring instrument is installed on the top of the mounting seat.

[0019] By adopting the above technical solution, when the angle of the laser measuring instrument needs to be adjusted horizontally, the staff can use the electric turntable to rotate the bracket, the mounting base and the laser measuring instrument horizontally. When the angle of the laser measuring instrument needs to be adjusted vertically, the staff can use the motor to drive the mounting base to rotate, thereby rotating the laser measuring instrument vertically.

[0020] Furthermore, the mounting seat is rotatably connected to the bracket.

[0021] By adopting the above technical solution, when the angle of the laser measuring instrument needs to be adjusted vertically, the staff can drive the mounting base to rotate through the motor, thereby making the laser measuring instrument rotate vertically.

[0022] Furthermore, four universal brake wheels are respectively connected to both sides of the bottom of the base, and the four universal brake wheels are distributed in a rectangular array.

[0023] By adopting the above technical solution, a universal brake wheel can be installed at the bottom of the base, which can facilitate the movement of the mechanism to other places for measurement. After the universal brake wheel is installed, the brake structure of the universal brake wheel can be used to prevent the mechanism from being displaced after the wheel frame is raised and retracted.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] The utility model is provided with a guide frame, a screw rod, an adjustment frame, a wheel frame, a positioning rod, a positioning groove and a roller. When horizontal adjustment is required, the wheel frame is rotated ninety degrees to make the roller face the X-axis or the Z-axis, and then the screw rod is rotated. After the screw rod is rotated, it cooperates with the guide frame to guide the adjustment frame to drive the wheel frame to move downward. After the wheel frame moves downward, the roller contacts the ground, and at the same time, the positioning rod enters the positioning groove to ensure that the wheel frame is perpendicular to the X-axis and the Z-axis. Then, the mechanism can be pushed to move in the X-axis direction or the Z-axis direction. After the adjustment is completed, the screw rod is reversed, so that the wheel frame drives the roller to move upward. At this time, the base contacts the ground to generate friction to avoid displacement of the mechanism, and at the same time, the positioning rod is moved out of the positioning groove so as to adjust to other directions. The utility model is convenient for large-size horizontal adjustment and is flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Next, according to the overall structure of the present invention, its embodiments will be described.

A lead screw 9 penetrates through the top of the guide frame 8. A handwheel is fixed at the top end of the lead screw 9. An adjusting frame 10 is connected between the lead screw 9 and the guide frame 8. The adjusting frame 10 is threadedly connected to the lead screw 9 and slidably connected to the guide frame 8. By rotating the lead screw 9, after the lead screw 9 rotates and is guided by the guide frame 8, the adjusting frame 10 drives the wheel frame 11 to move downward. After the wheel frame 11 moves downward, the roller 14 contacts the ground and jacks up the base 1; the wheel frame 11 is sleeved outside the adjusting frame 10. The cross-section of the adjusting frame 10 is in the shape of "I". The wheel frame 11 is rotatably connected to the adjusting frame 10. Rotating the wheel frame 11 by ninety degrees makes the roller 14 face the X-axis or the Z-axis; the wheel frame 11 is internally connected with rollers 14. There are four rollers 14, and the four rollers 14 are symmetrically distributed. After the wheel frame 11 moves downward, the rollers 14 contact the ground, and then the staff can push the mechanism to displace along the X-axis direction or the Z-axis direction; a positioning rod 12 is connected to one side of the bottom of the wheel frame 11. A positioning groove 13 is opened on the inner wall of the base 1. There are four positioning rods 12 and positioning grooves 13, and the four positioning rods 12 and positioning grooves 13 are both distributed in an annular array. The positioning rod 12 enters the positioning groove 13 to ensure that the wheel frame 11 is perpendicular to the X-axis and the Z-axis.

[0035] Refer to Figure 1 , in the above embodiment, an electric turntable 2 is installed on the top of the base 1. When the angle of the laser measuring instrument 6 needs to be horizontally adjusted, the staff can horizontally rotate the bracket 3, the mounting seat 4 and the laser measuring instrument 6 through the electric turntable 2; the output end of the electric turntable 2 is connected to a bracket 3. A motor 5 is installed on one side of the bracket 3. The output end of the motor 5 is connected to a mounting seat 4. The mounting seat 4 is rotatably connected to the bracket 3. A laser measuring instrument 6 is installed on the top of the mounting seat 4. When the angle of the laser measuring instrument 6 needs to be vertically adjusted, the staff can drive the mounting seat 4 to rotate through the motor 5, so that the laser measuring instrument 6 rotates vertically.

[0036] Embodiment 2:

[0037] On the basis of the above-mentioned embodiment 1, in order to facilitate the movement of the mechanism to other areas for use, the following settings are now adopted.

[0038] See also Figures 1 - 4 In the above embodiment, four universal brake wheels 7 are respectively connected to both sides of the bottom of the base 1, and the four universal brake wheels 7 are distributed in a rectangular array. The universal brake wheel 7 can be installed at the bottom of the base 1. The universal brake wheel 7 facilitates the movement of the mechanism to other places for measurement. After the universal brake wheel 7 is installed, the wheel frame 11 rises and is retracted, and the brake structure of the universal brake wheel 7 is used to prevent the mechanism from being displaced.

[0039] The implementation principle of the utility model is as follows: first, when the angle of the laser measuring instrument 6 needs to be adjusted horizontally, the staff can use the electric turntable 2 to rotate the bracket 3, the mounting seat 4 and the laser measuring instrument 6 horizontally; when the angle of the laser measuring instrument 6 needs to be adjusted vertically, the staff can use the motor 5 to drive the mounting seat 4 to rotate, thereby rotating the laser measuring instrument 6 vertically;

[0040] When horizontal adjustment is required, the staff rotates the wheel frame 11 90 degrees to make the roller 14 face the X-axis or Z-axis, and then the staff rotates the screw rod 9. After the screw rod 9 rotates, it cooperates with the guide frame 8 to guide the adjustment frame 10 to drive the wheel frame 11 to move downward. After the wheel frame 11 moves downward, the roller 14 contacts the ground and lifts the base 1. At the same time, the positioning rod 12 enters the positioning groove 13 to ensure that the wheel frame 11 is perpendicular to the X-axis and the Z-axis. Then the staff can push the mechanism to move in the X-axis direction or the Z-axis direction. After the adjustment is completed, the staff reverses the screw rod 9, so that the wheel frame 11 drives the roller 14 to move upward. At this time, the base 1 contacts the ground to generate friction to avoid displacement of the mechanism. At the same time, the positioning rod 12 is moved out of the positioning groove 13 to adjust to other directions;

[0041] A universal brake wheel 7 can also be installed at the bottom of the base 1, which can facilitate the movement of the mechanism to other places for measurement. After the universal brake wheel 7 is installed, the brake structure of the universal brake wheel 7 can be used to prevent the mechanism from being displaced after the wheel frame 11 is raised and retracted.
