Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of measuring equipment, in particular to a total station equipment. BACKGROUND

[0002] The total station, that is, the total station type electronic speed measuring instrument, refers to that after observation at the measuring station, necessary observation data such as slant distance, zenith distance (vertical angle), horizontal angle and the like can be automatically displayed, and horizontal distance, height difference and point coordinates can be obtained almost at the same time. If the data terminal of the total station type speed measuring instrument collected in the field is connected with a computer and a plotter through a transmission interface, and data processing software and drawing software are provided, the automation of mapping can be realized, and the total station is widely used in precise engineering measurement or deformation monitoring fields of large ground buildings and underground tunnels. The Chinese patent application No. 202120592205.9 discloses a total station, relating to the field of measuring equipment, which comprises a base, a supporting mechanism and a machine body. The supporting mechanism comprises three supporting legs, the upper ends of which are hinged to the base. An auxiliary leveling assembly is arranged below the base, which comprises a measuring ring.

[0034] By inserting the first clamping block 509 into the limiting seat 510, the first clamping block 509 pushes the second clamping block 512 away at this time, and then the second clamping block 512 is reset by the torsion springs 513 and clamps the first clamping block 509, so that the cylinder cover 507 closes the top end of the detection cylinder 515 and fixes the detection cylinder 515 in the mounting cylinder 502.

[0035] In this embodiment, as shown in Figure 5 As shown, the pouring detection mechanism 5 comprises a conductive head 516, a conductive rod 517, a detection block 518 and a conductive liquid 519, the conductive head 516 is fixedly installed at the middle of the bottom end of the detection cylinder 515, the conductive rod 517 is located in the middle of the inside of the detection cylinder 515 and is fixedly connected with the conductive head 516 at the bottom end, the detection block 518 is fixedly installed at the middle of the top end of the inside of the detection cylinder 515, and the conductive liquid 519 is arranged in the inside of the detection cylinder 515.

[0036] The conductive head 516 at the bottom end of the detection cylinder 515 is connected with the conductive column 504, and the detection block 518 is also connected with the upper conductive sheet 508, and when the cylinder cover 507 presses down the detection cylinder 515, the detection cylinder 515 drives the movable plate 503 to descend, and the movable plate 503 drives the conductive column 504 to descend, so that the conductive column 504 is connected with the lower conductive sheet 506, when the device is poured, the conductive liquid 519 in the detection cylinder 515 is tilted with the device, when the conductive liquid 519 contacts the detection block 518, the lower conductive sheet 506 is connected with the upper conductive sheet 508 through the conductive column 504, the conductive head 516, the conductive rod 517, the conductive liquid 519 and the detection block 518, so that the electric push rod 617 is triggered and started.

[0037] In other aspects, the embodiment also provides a pouring protection mechanism 6 for protecting the device from pouring, as shown in Figure 6 As shown, the pouring protection mechanism 6, the pouring protection mechanism 6 comprises first protection legs 602 and second protection legs 603, the first protection legs 602 are three in total and are evenly arranged at the bottom end of the mounting table 1, and the second protection legs 603 are arranged at the bottom end of each first protection leg 602.

[0038] In this embodiment, as shown inFigure 7 As shown, the tipping protection mechanism 6 includes a connecting rod 601, a lifting ring 604, a second spring 605, a first connecting frame 606, and a rotating cylinder 607. The connecting rod 601 is fixedly installed in the middle of the bottom end of the mounting platform 1. The lifting ring 604 is movably sleeved on the bottom end of the connecting rod 601. The second spring 605 is movably sleeved on the bottom end of the connecting rod 601 and is located between the bottom end of the connecting rod 601 and the lifting ring 604. There are three first connecting frames 606, and one end close to the lifting ring 604 is evenly and movably connected to the lifting ring 604, while the other end is movably installed in the middle of the inside of the connecting rod 601. There are three rotating cylinders 607, which are movably installed inside the connecting rod 601 and are located below the end of the lifting ring 604 away from the connecting rod 601.

[0039] The lifting ring 604 rises due to the elastic force of the second spring 605. When the lifting ring 604 rises, the first protective leg 602 rotates away from the connecting rod 601 through the first connecting frame 606. At this time, the first connecting frame 606 no longer contacts the damping block 610, so that the rotating cylinder 607 is released from restriction. Then, under the elastic force of the third spring 608, the extension rod 609 is ejected from the rotating cylinder 607.

[0040] In this embodiment, as Figure 7 and Figure 8 As shown, the tipping protection mechanism 6 includes a third spring 608, an extension rod 609, a damping block 610, a limiting frame 611, and a sliding rod 612.

There are three sliding rods 612, which are evenly fixedly installed at the bottom of the connecting rod 601, and the other end is fixedly installed in the middle of the bottom of the limiting frame 611.

[0041] The electric actuator 617 drives the clamping plate 613 to move away from the connecting rod 601, thereby releasing the lifting ring 604 from its limit. When the first protective leg 602 rotates, the third spring 608 pops out the extension rod 609 to drive the first protective leg 602 to rotate.

[0042] In this embodiment, as Figure 9As shown, the pouring protection mechanism 6 comprises three clamping plates 613, three second connecting frames 614, a hanging frame 615, a lifting plate 616, an electric push rod 617 and a battery box 618, the three clamping plates 613 are uniformly arranged at the bottom end of the connecting rod 601 and movably installed in the limiting frame 611, the three second connecting frames 614 are movably installed at the bottom end of the three clamping plates 613 respectively, the hanging frame 615 is fixedly installed at the bottom end of the connecting rod 601, the lifting plate 616 is movably installed in the hanging frame 615, the second connecting frame 614 is movably connected with the lifting plate 616 at the end away from the clamping plate 613, the electric push rod 617 is fixedly installed at the middle of the bottom end of the hanging frame 615, and the output shaft is fixedly connected with the middle of the bottom end of the lifting plate 616 after penetrating through the hanging frame 615, and the battery box 618 is fixedly installed at the bottom end of the electric push rod 617.

[0043] When the lifting plate 616 is lifted by the electric push rod 617, the clamping plate 613 is moved away from the connecting rod 601 by the second connecting frame 614, at this time, the lifting ring 604 is lifted by the elastic force of the second spring 605, when the lifting ring 604 is lifted, the first protection leg 602 is rotated away from the connecting rod 601 by the first connecting frame 606, at this time, the first connecting frame 606 is no longer in contact with the damping block 610, so that the rotating cylinder 607 is released, at this time, the extending rod 609 is popped out of the rotating cylinder 607 under the elastic force of the third spring 608, so that the second protection leg 603 is rotated and unfolded away from the first protection leg 602, and the first protection leg 602 and the second protection leg 603 unfolded are used to protect the device that is about to fall.

[0044] Working principle: when the present application is used, the telescopic leg 2 is opened and the height is adjusted, then the telescopic leg 2 is fixed, the supporting rod 3 is unfolded after the telescopic leg 2 is unfolded, the supporting rod 3 is fixed through the fixing cover 4, the total station 7 is installed on the mounting table 1, then the detection cylinder 515 is inserted into the mounting cylinder 502, and the cylinder cover 507 is covered, so that the first clamping block 509 is inserted into the limiting seat 510, at this time, the first clamping block 509 is opened by the second clamping block 512, then the second clamping block 512 is reset by the torsional spring 513 and the first clamping block 509 is clamped, at this time, the cylinder cover 507 seals the top end of the mounting cylinder 502, and the conductive head 516 at the bottom end of the detection cylinder 515 is connected with the conductive column 504, the detection block 518 is connected with the upper conductive sheet 508, and when the cylinder cover 507 presses the detection cylinder 515, the movable plate 503 is lowered by the descending detection cylinder 515, the conductive column 504 is lowered by the movable plate 503, and the conductive column 504 is connected with the lower conductive sheet 506.

[0045] When the device is about to fall, the conductive liquid 519 in the detection cylinder 515 is tilted at the same time, when the conductive liquid 519 contacts the detection block 518, the lower conductive sheet 506 is conducted with the upper conductive sheet 508 through the conductive column 504, the conductive head 516, the conductive rod 517, the conductive liquid 519 and the detection block 518, so that the electric push rod 617 is triggered to start, and the lifting plate 616 is lifted through the electric push rod 617, when the lifting plate 616 is lifted, the clamping plate 613 is moved away from the connecting rod 601 through the second connecting frame 614, at this time the lifting ring 604 is lifted by the elastic force of the second spring 605, when the lifting ring 604 is lifted, the first protection leg 602 is rotated away from the connecting rod 601 through the first connecting frame 606, at this time the first connecting frame 606 is no longer in contact with the damping block 610, so that the rotating cylinder 607 is released, at this time the extending rod 609 is popped out of the rotating cylinder 607 under the elastic force of the third spring 608, so that the second protection leg 603 is rotated and unfolded away from the first protection leg 602, and the whole device about to fall is protected through the unfolded first protection leg 602 and the second protection leg 603.

[0046] When the device falls, the second protection leg 603 contacts the ground first, at this time the second protection leg 603 is rotated and the extending rod 609 is inserted into the rotating cylinder 607, so that the third spring 608 is squeezed, the movement of the extending rod 609 is hindered by the elastic force of the third spring 608, so that the rotation of the second protection leg 603 is buffered, and the first protection leg 602 is also rotated by the impact and drives the lifting ring 604 to descend through the first connecting frame 606, at this time the descent of the lifting ring 604 is hindered by the second spring 605, so that the rotation of the first protection leg 602 is buffered, so as to buffer the impact force generated when the device falls, and further protect the total station 7 on the mounting table 1.
