Description

Technical Field

[0001] The invention relates to the technical field of electric lifting tripods, in particular to an automatically positioned electric lifting tripod. Background Art

[0002] A tripod is a stable support device with three supporting legs as its basic structure. It is widely used in scenes such as photography, surveying and mapping, engineering, and scientific research that require stable support for equipment. Its core design uses the geometric stability principle of a triangle to achieve the fixation and height and angle adjustment of the equipment through adjustable legs and top connection mechanisms. For convenience, many tripods are designed with electrically controlled adjustable legs and top connection mechanisms.

[0003] In the existing technology, workers place corresponding laser detectors on the wall and then adjust the height of the tripod manually. However, this cannot ensure that the level can be raised and lowered accurately, which easily causes errors in the vertical distance and affects the operation results. Summary of the Invention

[0004] The object of the present invention is to provide an automatically positioned electric lifting tripod to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the automatic positioning electric lifting tripod includes a laser detector and three bases, each of the three bases is provided with a spherical groove, each of the three spherical grooves is rotatably installed with a spherical shaft, the diameter of each spherical shaft is larger than the notch of the spherical groove, each of the three spherical shafts is installed with an electric telescopic rod, the telescopic end of the electric telescopic rod is provided with a carrier, the carrier is symmetrically provided with a main shaft telescopic rod, the telescopic end of the main shaft telescopic rod is provided with a turntable, a signal receiver is provided on one side of the turntable, a sensor controller is installed on the turntable, a four-claw chuck is installed on the turntable, the sensor controller is connected to the electric telescopic rod, the main shaft telescopic rod and the signal receiver The device is electrically connected, and the staff holds a handheld laser detector and installs it on the wall. The laser detector transmits a positioning signal to the signal receiver. After receiving the positioning signal, the signal receiver feeds back to the sensor controller, so that the sensor controller can quickly and effectively control the extension and retraction of the electric telescopic rod. Through the rotation coordination of the spherical shaft and the spherical groove, the distance in the horizontal and vertical directions can be slightly adjusted. By controlling the extension and retraction of the main shaft telescopic rod, a large lift in the vertical direction can be performed. When the laser emitted by the spirit level on the four-jaw chuck hits the laser detector, the signal receiver receives the feedback signal and controls the electric telescopic rod and the main shaft telescopic rod to stop extending and retracting, and the electric tripod stops lifting and lowering, thereby realizing the automatic positioning of the spirit level driven by the electric tripod.

[0011] A shell is symmetrically slidably installed in the card slot, and a fixing slot is provided on both of the shells. A fixed shaft is installed in the fixing slot, and a connecting rod is rotatably installed on the fixed shaft.

[0012] As an optimal technical solution, a level detection sensor is installed at the bottom of the platform, and the level detection sensor is electrically connected to the sensor controller. When the tripod is located in a non-horizontal plane, the level detection sensor detects that the platform is not in a horizontal state, and controls the lower electric telescopic rod to extend and the other electric telescopic rods to retract, and the electric telescopic rods are hingedly connected to the platform to restore the platform to a horizontal state, ensuring that the spirit level is always in a horizontal position. Through the rotation cooperation of the spherical shaft and the spherical groove, the base is always perpendicular to the contact surface, thereby ensuring the stability of the tripod and preventing it from tipping over.

[0013] As an optimal technical solution, a fixed telescopic rod is installed at the bottom of the level detection sensor, and a bracket telescopic rod is evenly installed on the fixed telescopic rod. The fixed telescopic rod is hinged to the bracket telescopic rod, and the other end of the bracket telescopic rod is hinged to the base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The staff holds a handheld laser detector and installs it on the wall. The laser detector transmits the positioning signal to the signal receiver. After receiving the positioning signal, the signal receiver feeds back to the sensor controller, which controls the electric telescopic rod and the main shaft telescopic rod to raise and lower the tripod.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example: Figures 1-8As shown, the present invention provides a technical solution for an automatically positioned electric lifting tripod, which includes a laser detector and three bases 1. The three bases 1 are each provided with a spherical groove 2. Spherical shafts 3 are rotatably installed in the three spherical grooves 2. The diameters of the spherical shafts 3 are all larger than the notches of the spherical grooves 2. An electric telescopic rod 4 is installed on the three spherical shafts 3. The telescopic end of the electric telescopic rod 4 is provided with a carrier 501. The carrier 501 is symmetrically provided with a main shaft telescopic rod 8. The telescopic end of the main shaft telescopic rod 8 is provided with a turntable 506. A signal receiver 611 is provided on one side of the turntable 506. A sensor controller 7 is installed on the turntable 506. A four-claw chuck 12 is installed on the turntable 506. The sensor controller 7 is connected to the electric telescopic rod 4, the main shaft telescopic rod 8 and the signal receiver 611. The receiver 611 is electrically connected, and the staff holds a laser detector and installs it on the wall. The positioning signal is transmitted to the signal receiver 611 through the laser detector. After receiving the positioning signal, the signal receiver 611 feeds back to the sensor controller 7, so that the sensor controller 7 can quickly and effectively control the extension and retraction of the electric telescopic rod 4. Through the rotation coordination of the spherical shaft 3 and the spherical groove 2, the distance in the horizontal and vertical directions can be slightly adjusted. By controlling the extension and retraction of the main shaft telescopic rod 8, a large lift in the vertical direction can be performed. When the laser emitted by the spirit level on the four-jaw chuck 12 irradiates the laser detector, the signal receiver 611 receives the feedback signal and controls the electric telescopic rod 4 and the main shaft telescopic rod 8 to stop extending and retracting, and the electric tripod stops lifting and lowering, thereby realizing the automatic positioning of the spirit level driven by the electric tripod.

[0032] The three electric telescopic rods 4 are connected by a support assembly 5 , and a signal receiving assembly 6 is provided on one side of the support assembly 5 .

[0033] like Figures 1-4 and Figure 7-Figure 8 As shown, the support assembly 5 includes an external frame 502, a connecting shaft 503, a slot 507, a rotating groove 508 and a rotating wheel 509. The external frame 502 is evenly and symmetrically installed outside the carrier 501. The connecting shaft 503 is rotatably installed between the two symmetrical external frames 502 and is connected by the connecting shaft 503. A connecting hole is provided on the telescopic end of the electric telescopic rod 4, and the connecting shaft 503 passes through the connecting hole. A slot 507 is provided on one side of the turntable 506, and a rotating groove 508 is provided in the turntable 506. A rotating wheel 509 is rotatably installed in the rotating groove 508. The main shaft telescopic rod 8 is symmetrically installed on the carrier 501, and the telescopic end of the main shaft telescopic rod 8 is connected to the rotating wheel 509.

[0034] The support assembly 5 also includes an inner groove 504 and a rotating motor 505. The inner groove 504 is opened on the carrier 501, and the rotating motor 505 is installed in the inner groove 504. The output end of the rotating motor 505 is installed with a driven telescopic shaft 510. The telescopic ends of the master and slave telescopic shafts 510 are connected to the axis of the turntable 506. When the level is running, the rotating motor 505 is started by the sensor controller 7, thereby driving the turntable 506 to rotate through the main shaft telescopic rod 8, and then the level can be turned to achieve the effect of multi-directional operation.

[0035] like Figure 1-Figure 2 and Figure 5-Figure 8 As shown, the signal receiving assembly 6 includes a housing 601, a fixing slot 602, a fixing shaft 603, a connecting rod 604, a protrusion 605, a center rod 606, a long plate 607, an external block 608, a connecting column 609 and a connecting plate 610. The housing 601 is symmetrically slidably installed in the card slot 507. The two housings 601 are each provided with a fixing slot 602. The fixing slot 602 is each installed with a fixing shaft 603. The fixing shaft 603 is rotatably installed with a connecting rod 604. The end of the connecting rod 604 away from the fixed shaft 603 is equipped with a protrusion 605, and the protrusion 605 is connected to the housing 601 through a spring. The housing 601 is symmetrically provided with connecting grooves, and the protrusion 605 passes through the connecting grooves and is connected to the two connecting rods 604. The housing 601 is connected through a center rod 606. A long plate 607 is installed on the protrusion 605, and a center hole is provided on the long plate 607. The center rod 606 passes through the center hole. The housing 601 is away from the protrusion 605. One end of each is equipped with an external block 608, and a connecting column 609 is installed at the bottom of the external block 608. A connecting plate 610 is fixedly installed at the bottom of the connecting column 609, and a signal receiver 611 is installed at the bottom of the connecting plate 610. When the tripod is not used for work, by pushing the end of the long plate 607 upwards, the lever principle can be used to move the protrusion 605 downward to squeeze the spring. At the same time, the long plate 607 is pulled outward, so that the signal receiver 611 can be removed, achieving convenient and quick disassembly. When the tripod is used for work, by pushing the end of the long plate 607 upwards, the lever principle can be used to move the protrusion 605 downward to squeeze the spring. At the same time, the long plate 607 is pushed to make the housing 601 enter the slot 507. By stopping toggling the long plate 607, the elastic deformation of the spring causes the protrusion 605 to be stuck in the L-shaped slot 507, so that the signal receiver 611 can be fixedly installed, achieving quick and convenient installation.

[0036] like Figure 2-Figure 3As shown, a level detection sensor 9 is installed at the bottom of the platform 501, and the level detection sensor 9 is electrically connected to the sensor controller 7. When the tripod is located in a non-horizontal plane, the level detection sensor 9 detects that the platform 501 is not in a horizontal state, and controls the lower electric telescopic rod 4 to extend and the other electric telescopic rods 4 to retract, and the electric telescopic rod 4 is hingedly connected to the platform 501 to restore the platform 501 to a horizontal state, ensuring that the spirit level is always in a horizontal position, and through the rotation cooperation of the spherical shaft 3 and the spherical slot 2, the base 1 is always perpendicular to the contact surface, thereby ensuring the stability of the tripod and not prone to tilting.

[0037] like Figures 1-4 and Figure 7 As shown, a fixed telescopic rod 10 is installed at the bottom of the level detection sensor 9, and a bracket telescopic rod 11 is evenly installed on the fixed telescopic rod 10. The fixed telescopic rod 10 is hinged to the bracket telescopic rod 11, and the other end of the bracket telescopic rod 11 is hinged to the base 1. When the fixed tripod is installed, the bracket telescopic rod 11 is connected to the fixed telescopic rod 10 and the base 1 through a hinge, and through the corresponding extension and contraction of the bracket telescopic rod 11, when the base 1 is in planes at different heights, the bracket telescopic rod 11 and the fixed telescopic rod 10 always fix the tripod, ensuring the stability of the tripod, and at the same time realizing the horizontal adjustment of the carrier 501, further ensuring that the spirit level is always in a horizontal position.

[0038] like Figures 1-4 and Figure 7 As shown, a semicircular support foot 13 is installed at the bottom of the base 1. When the tripod is on an uneven ground, the semicircular support foot 13 at the bottom allows the tripod to have a reserved contact space with the ground, so that the tripod will not shake due to the uneven ground, thereby ensuring the stability of the level when working.

[0039] Working principle of the present invention:

[0040] The staff holds a handheld laser detector and installs it on the wall, and transmits a positioning signal to the signal receiver 611 through the laser detector. After receiving the positioning signal, the signal receiver 611 feeds back to the sensor controller 7, so that the sensor controller 7 can quickly and effectively control the extension and retraction of the electric telescopic rod 4. Through the rotation coordination of the spherical shaft 3 and the spherical groove 2, the distance in the horizontal and vertical directions can be slightly adjusted. By controlling the extension and retraction of the main shaft telescopic rod 8, a large lift in the vertical direction can be performed. When the signal receiver 611 reaches the signal specified position, the electric telescopic rod 4 and the main shaft telescopic rod 8 stop extending and retracting, and the electric tripod stops lifting and lowering, thereby realizing the automatic positioning of the level meter driven by the electric tripod.

[0041] When the level is in operation, the sensor controller 7 controls the rotation motor 505 to start, thereby driving the turntable 506 to rotate through the main shaft telescopic rod 8, thereby making the level turn, thereby achieving a multi-directional working effect.

[0042] When working without a tripod, by pushing the end of the long plate 607 upwards, due to the principle of leverage, the protrusion 605 can be moved downward to squeeze the spring. At the same time, the long plate 607 can be pulled outward to remove the signal receiver 611, thereby achieving convenient and quick disassembly. When working with a tripod, by pushing the end of the long plate 607 upwards, due to the principle of leverage, the protrusion 605 can be moved downward to squeeze the spring. At the same time, the long plate 607 is pushed to make the housing 601 enter the slot 507. By stopping pushing the long plate 607, the protrusion 605 is snapped into the L-shaped slot 507 due to the elastic deformation of the spring, thereby fixing the signal receiver 611, thereby achieving quick and convenient installation.

[0043] When the tripod is located on a non-horizontal plane, the level detection sensor 9 detects that the platform 501 is not in a horizontal state. By controlling the lower electric telescopic rod 4 to extend and the other electric telescopic rods 4 to retract, and the electric telescopic rod 4 is hingedly connected to the platform 501, the platform 501 is restored to a horizontal state, ensuring that the spirit level is always in a horizontal position. Through the rotation cooperation of the spherical shaft 3 and the spherical slot 2, the base 1 is always perpendicular to the contact surface, thereby ensuring the stability of the tripod and preventing it from tipping over.

[0044] When installing a fixed tripod, the support telescopic rod 11 is connected to the fixed telescopic rod 10 and the base 1 through a hinge, and through the corresponding extension and contraction of the support telescopic rod 11, when the base 1 is on planes at different heights, the support telescopic rod 11 and the fixed telescopic rod 10 always fix the tripod, ensuring the stability of the tripod, and at the same time achieving the horizontal adjustment of the platform 501, further ensuring that the spirit level is always in a horizontal position.

[0045] When the tripod is on an uneven ground, the semicircular support legs 13 at the bottom provide a reserved contact space between the tripod and the ground, so that the tripod will not shake due to the uneven ground, thereby ensuring the stability of the level when working.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
