Description

Technical Field

[0001] The invention relates to the technical field of measuring instruments, and in particular to a multi-directional swing angle measuring instrument and a use method thereof. Background Art

[0002] Geological exploration is a geological measurement process necessary for operations such as road construction. Before geological exploration, the support frame of the angle measuring instrument needs to be installed on the ground after measurement and leveling, and the measuring instrument needs to be installed on the support frame to measure and record the ground information. The error size of the recorded information is closely related to the error after road construction, so the angle measurement process is very important.

[0003] When using an angle measuring instrument to survey information, if the frame is fixed by a support frame, the frame may tip over if the stability of the frame is not maintained. After installing the measuring instrument, it is necessary to maintain the stability of the fixing between the measuring instrument and the frame. When adjusting the height of the measuring instrument, if the center of gravity of the frame is not adjusted, the frame may tip over when subjected to a small external force.

[0004] In view of the shortcomings of the prior art, the present invention provides a multi-directional swing angle measuring instrument and a method of use, which has the advantages of stable installation of the measuring instrument and avoids instability caused by rising center of gravity when height is adjusted, solving the problem of unstable installation of the measuring instrument and instability caused by rising center of gravity when height is adjusted. Summary of the invention

[0005] In order to achieve the purpose of stable installation of the above-mentioned measuring instrument and avoid instability caused by rising center of gravity during height adjustment, the present invention provides the following technical solution: a multi-directional swing angle measuring instrument, comprising a table body, the bottom of the edge of the table body is movably connected to a supporting device, the bottom end of the table body is movably connected to a driving device, the top of the table body is movably connected to an adjusting device, and the top of the adjusting device is rotatably connected to a fixing device.

[0006] As an optimization, the supporting device includes side plates, both sides of which are rotatably connected to rotating rods, the surface of the rotating rods is rotatably connected to the support rods, the surface of the support rods is fixedly installed with a fixed rod, the center of the bottom end of the platform body is fixedly installed with a vertical rod, and the surface of the vertical rod is slidably connected with a counterweight block.

[0007] As an optimization, the side panels are evenly spaced on the sides of the platform, and the fixing rods are retractable, so that the fixing rods always keep the symmetrically installed support rods in a stable state when rotating.

[0008] As an optimization, the driving device includes a slide groove, a return spring is fixedly installed at one end of the slide groove away from the center of the platform, a slider is fixedly installed at one end of the return spring close to the center of the platform, a connecting rod is movably connected to the bottom end of the slider, and a magnetic block is fixedly installed at one end of the slide groove close to the center of the platform.

[0009] As an optimization, an electromagnet is fixedly installed inside the slider, and the end of the electromagnet and the magnetic block that are close to each other have heterogeneous magnetic poles. The bottom end of the connecting rod is movably connected to the counterweight block. When the electromagnet is energized, it attracts the magnetic block, so that the slider drives the connecting rod to rotate and then drives the counterweight block to move.

[0010] As an optimization, the adjusting device includes an internally threaded rod, the internal movably connected to an externally threaded rod, a top plate is fixedly installed on the top end of the externally threaded rod, an inner groove is opened at the bottom end of the top plate, a connecting pin is movably connected inside the inner groove, the bottom end of the connecting pin is fixedly connected to a pull rod, the bottom end of the pull rod is movably connected to a contact, and a resistance bar is fixedly installed at the center of the top end of the platform body.

[0011] As an optimization, the interior of the externally threaded rod is hollow, the resistor bar is fixedly installed inside the externally threaded rod, the contact is movably connected to the surface of the resistor bar, the resistance of the resistor bar gradually decreases as the contact moves upward, and the movement of the externally threaded rod drives the contact to move, thereby causing the resistance of the resistor bar to change. The resistor bar is electrically connected to the electromagnet, and the amount of current flowing through the electromagnet changes when the resistance of the resistor bar changes. The interior of the platform is hollow, and a power supply electrically connected to the electromagnet and the resistor bar is provided inside the platform.

[0012] As an optimization, the fixing device includes a fixing platform, a cylinder is fixedly installed on the inner wall of the fixing platform, an end of the cylinder away from the inner wall of the fixing platform is movably connected to a piston rod, an end of the piston rod away from the cylinder is fixedly installed with a connecting block, an end of the connecting block away from the piston rod is movably connected to a control switch, and the left and right sides of the connecting block are rotatably connected to limit rods.

[0013] As an optimization, a contact compatible with the control switch is fixedly installed inside the connecting block, and an electromagnet is fixedly installed inside the connecting block. The control switch and the electromagnet are electrically connected. After the control switch and the contact are in contact, the electromagnet is energized, thereby driving the limit rods on the left and right sides of the connecting block to rotate towards each other and approach each other.

[0014] As an optimization, the method of using the multi-directional swing angle measuring instrument is as follows:

[0015] S1: Insert the support rod into the ground and adjust the support rod to rotate. When the support rod rotates, it always remains stable due to the action of the fixed rod. When it is adjusted to a suitable height and the platform is horizontal, stop adjusting and place the measuring instrument on the top of the fixed platform;

[0016] S2: driving the cylinder to extend the piston rod, and the extension of the piston rod drives the fixed connection block to move toward the measuring instrument. When the connection block contacts the measuring instrument, it is initially fixed;

[0017] S3: At the same time, the control switch moves toward the contact point under the action of the reaction force when it contacts the measuring instrument. When the control switch and the contact are in contact, the electromagnet is energized. At this time, the electromagnets attract each other and drive the fixed limit rods to rotate and approach each other, thereby performing secondary fixation on the measuring instrument, so that the measuring instrument remains in a stable state when in use or adjusted;

[0018] S4: When the angle of the measuring instrument needs to be adjusted, the fixed platform can be directly rotated. When the height of the measuring instrument needs to be adjusted, the external threaded rod is rotated so that the external threaded rod and the internal threaded rod are engaged with each other. Since the internal threaded rod and the platform body are mutually limited, the external threaded rod rises. When the external threaded rod rises, the top plate is driven to rise, and then the fixed platform is driven to rise, so that the height of the measuring instrument is adjusted;

[0019] S5: As the top plate rises, the movably connected connecting pin is driven to rise inside the inner groove. When the connecting pin rises, the contact is driven to rise through the pull rod, thereby reducing the resistance of the resistor bar and increasing the amount of current flowing into the electromagnet electrically connected to the resistor bar. The electromagnet drives the slider to approach the magnetic block. When the slider moves, it drives the movably connected connecting rod to rotate, thereby driving the counterweight block movably connected to the connecting rod to slide downward on the surface of the vertical rod, so that the center of gravity of the device will not rise with the rise of the fixed platform, thereby maintaining the stability of the device when in use.

[0020] The beneficial effects of the present invention are as follows: the multi-directional swing angle measuring instrument and the use method, by placing the measuring instrument on the top of the fixed platform, fix the measuring instrument from various angles, so that the measuring instrument will not fall off the fixed platform during use; after the support device completes the installation of the platform body, the limit rod is used to prevent the support rod from sliding, thereby keeping the platform body stable; the measuring angle of the measuring instrument can be adjusted by rotating the fixed platform; when the height of the measuring instrument needs to be adjusted, the fixed platform is raised or lowered by adjusting the rotation of the external threaded rod, thereby adjusting the height; and while adjusting the height, the height of the counterweight block is adjusted, so that the center of gravity of the device will not increase significantly with the increase of the fixed platform, thereby increasing the overall stability of the device and preventing the support rod from tipping over during use.

The contact 47 is fixedly installed inside the external threaded rod 42, and the contact 47 is movably connected to the surface of the resistor bar 48. The resistance of the resistor bar 48 gradually decreases as the contact 47 moves upward. When the external threaded rod 42 moves, the contact 47 is driven to move, thereby causing the resistance of the resistor bar 48 to change. The resistor bar 48 is electrically connected to the electromagnet. When the resistance of the resistor bar 48 changes, the amount of current flowing through the electromagnet changes accordingly.

[0034] See also Figure 6 and 7The fixing device 5 includes a fixing platform 51, a cylinder 52 is fixedly installed on the inner wall of the fixing platform 51, a piston rod 53 is movably connected to one end of the cylinder 52 away from the inner wall of the fixing platform 51, a connecting block 54 is fixedly installed on one end of the piston rod 53 away from the cylinder 52, a control switch 55 is movably connected to one end of the connecting block 54 away from the piston rod 53, both left and right sides of the connecting block 54 are rotatably connected to limit rods 56, contacts adapted to the control switch 55 are fixedly installed inside the connecting block 54, an electromagnet is fixedly installed inside the connecting block 54, the control switch 55 is electrically connected to the electromagnet, and after the control switch 55 contacts are in contact with the electromagnet, the electromagnet is energized, thereby driving the limit rods 56 on the left and right sides of the connecting block 54 to rotate relative to each other and approach each other.

[0035] When in use, the support rod 23 is plugged into the ground and the support rod 23 is adjusted to rotate. When the support rod 23 rotates, it always remains in a stable state due to the action of the fixing rod 24. When it is adjusted to a suitable height and the platform 1 is horizontal, the adjustment is stopped, and the measuring instrument is placed on the top of the fixed platform 51, and the cylinder 52 is driven to drive the piston rod 53 to extend. The extension of the piston rod 53 drives the fixedly connected connecting block 54 to move toward the measuring instrument. When the connecting block 54 contacts the measuring instrument, it is initially fixed. At the same time, the control switch 55 moves in the direction of the contact point under the action of the reaction force when contacting the measuring instrument. When the control switch 55 and the contact are in contact, the electromagnet is energized. At this time, the electromagnets attract each other and drive the fixedly connected limit rod 56 to rotate and approach each other, thereby performing secondary fixation on the measuring instrument, so that the measuring instrument remains in a stable state when in use or adjustment. When the angle of the measuring instrument needs to be adjusted, the fixing platform 51 can be directly rotated. When the height of the instrument is adjusted, the external threaded rod 42 is rotated so that the external threaded rod 42 and the internal threaded rod 41 are meshed with each other. Since the internal threaded rod 41 and the platform body 1 are limited to each other, the external threaded rod 42 rises.

The electromagnet drives the slider 33 to approach the magnetic block 35. When the slider 33 moves, it drives the movably connected connecting rod 34 to rotate, thereby driving the counterweight block 26 movably connected to the connecting rod 34 to slide downward on the surface of the vertical rod 25, so that the center of gravity of the device will not rise with the rise of the fixed platform 51, thereby maintaining the stability of the device when in use.

[0036] In summary, the multi-directional swing angle measuring instrument and its use method, by placing the measuring instrument on the top of the fixed platform 51, fixes the measuring instrument from various angles, so that the measuring instrument will not fall off the fixed platform 51 during use. After the support device 2 installs the platform body 1, the fixing rod 24 is used to prevent the support rod 23 from sliding, thereby keeping the platform body 1 stable. The measuring angle of the measuring instrument can be adjusted by rotating the fixed platform 51. When the height of the measuring instrument needs to be adjusted, the fixed platform 51 is raised and lowered by adjusting the external threaded rod 42, and the height is adjusted. At the same time as the height is adjusted, the height of the counterweight block 26 is adjusted, so that the center of gravity of the device will not increase significantly with the increase of the fixed platform 51, thereby increasing the overall stability of the device and avoiding the support rod 23 from tipping over during use.
