Description

Technical Field

[0001] This application relates to the field of building construction technology, and more specifically, to a rapid deployment device for a total station. Background Technology

[0002] In core engineering fields such as engineering surveying, topographic mapping, construction layout, and geological disaster monitoring, the total station, as a key instrument with high-precision measurement capabilities, directly determines the quality control and progress of the overall operation through its deployment efficiency and setup stability. It is a core prerequisite for ensuring the accuracy of measurement data and the smoothness of the workflow. The tripod, as an indispensable core support for the total station, undertakes the basic functions of instrument positioning and leveling. Its operation process covers key aspects such as setup and deployment, height adjustment, level calibration, and fixing and locking. Among these, the tightening and adjustment of the tripod's telescopic legs is crucial throughout the entire setup, adjustment, and transfer process, and is a key factor affecting the tripod's support performance and ease of operation.

[0003] Currently, most mainstream total station tripods in the industry adopt a split-type fastening structure design, with each telescopic leg individually equipped with its own fastening bolt. Operators must manually tighten and loosen these bolts to lock and unlock the telescopic legs. In a single measurement operation, operators must adjust the length of each of the three telescopic legs one by one and then tighten the corresponding bolts to complete the basic setup of the tripod. However, in complex scenarios requiring multiple station changes, such as segmented surveying of road engineering, multi-point inspection of large factory areas, and multi-point monitoring of foundation pit deformation, the tripod must undergo frequent disassembly, relocation, and re-setup. During this process, operators must repeatedly open and close the fastening bolts of the three telescopic legs, and each bolt must be independently controlled and adjusted, making the operation cumbersome and highly repetitive.

[0004] The existing structure and operating mode have revealed numerous technical pain points in actual operation, restricting the efficiency and stability of total station operations. On the one hand, frequent and individual bolt operations significantly increase the labor intensity of operators, especially in scenarios with multiple locations and high-frequency station changes. Repeated operations significantly prolong deployment time, reduce overall operational efficiency, and make it difficult to meet the timeliness requirements of large-scale projects and emergency monitoring. On the other hand, the independent adjustment mode of the three bolts is prone to uneven locking force of the telescopic legs due to insufficient consistency in the operator's operating techniques and force control. This not only directly affects the support stability of the tripod, thus interfering with the setup accuracy of the total station, but also accelerates the wear of the bolts during long-term and frequent operations, shortens the service life of components, indirectly undermines the long-term stability of measurement accuracy, and poses potential risks to the quality of subsequent operations.

[0005] Therefore, there is an urgent need for a rapid deployment device for total stations. Summary of the Invention

[0011] In some embodiments, each of the locking mechanisms includes: a compression cylinder connected to the bottom connecting pipe of the sub-control valve pipe; two pistons correspondingly slidably disposed on both sides of the inner cavity of the compression cylinder and movable radially along the compression cylinder; two extrusion columns disposed on each of the pistons; two extrusion blocks disposed at one end of each extrusion column from the piston; and two rubber pads disposed on the inner side of each extrusion block, each extrusion pad being arc-shaped and capable of tightly abutting against the outer wall of the extension leg.

[0012] In some embodiments, the central control mechanism includes: a telescopic bladder disposed at the bottom of the mounting component, the telescopic bladder forming a sealed inner cavity; a base plate disposed at the bottom of the telescopic bladder; two guide pillars disposed on the base plate and correspondingly embedded inside the inner sides of two of the mounting compartments; two guide blocks fixedly disposed in the inner cavities of the mounting compartments corresponding to the two guide pillars, the guide pillars being movable up and down along the guide blocks; and three connecting pipes arranged along the circumference of the telescopic bladder, each connecting pipe having one end connected to the telescopic bladder and the other end connected to the top connecting pipe of the sub-control valve.

[0013] In some embodiments, the master control switch includes: a knob, rotatably disposed on the outside of a third mounting compartment other than the two guide columns; two rotating disks, both coaxially fixedly connected to the knob and built into the corresponding mounting compartments; a connecting column, fixedly disposed between the two rotating disks; a boom, one end connected to the connecting column and the other end connected to the base plate; and a stop block disposed on the inner side wall of the corresponding mounting compartment, which can abut against and limit the movement of the connecting column.

Through a central control mechanism, the device synchronously locks and unlocks three telescopic legs, significantly simplifying the setup and dismantling process and improving station change efficiency. The central control mechanism enables synchronous linkage control of the three locking mechanisms, eliminating the cumbersome process of manually operating each leg's fastening structure individually, as required by traditional devices. A single locking and unlocking operation completes the synchronous movement of all three extension legs, greatly shortening adjustment time. Simultaneously, the quick-locking mechanism enables rapid fixation of the total station base, further simplifying the assembly process and improving overall deployment and station change efficiency. It is particularly suitable for multi-point, high-frequency station change scenarios. Furthermore, the device combines synchronous control and independent adjustment. The central control mechanism enables overall synchronous locking and unlocking to meet rapid adjustment needs, while the individual control mechanisms can use pressure changes to individually control the clamping force of corresponding compression blocks, achieving precise fine-tuning of individual extension legs. This adapts to the setup requirements in complex terrains and enhances the device's adaptability in different operating scenarios.

[0022] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0024] The following reference Figures 1 to 15 This application describes a rapid deployment apparatus for a total station provided according to some embodiments.

[0025] like Figure 1 As shown, the total station rapid deployment device provided according to some embodiments of this application includes a tripod 100, sub-control mechanisms 200, locking mechanisms 300, a central control mechanism 400, and a quick-lock mechanism 600. The tripod 100 includes three rotating legs 130 and three extending legs 140. Each extending leg 140 can be adjusted up and down along the axial direction of the corresponding rotating leg 130. The tripod 100 provides a basic support carrier for the total station. The three sub-control mechanisms 200 are respectively located at the end of each rotating leg 130. The three locking mechanisms 300 are respectively disposed on each sub-control mechanism 200. Each locking mechanism 300 includes a pressing block 340, which is tightly fitted to the outer wall of the corresponding extending leg 140. Each sub-control mechanism 200 utilizes… Pressure changes can individually control the clamping force of the corresponding extrusion block 340; the main control mechanism 400, which is set on the tripod 100 and connected to the sub-control mechanisms 200, includes a compressible telescopic bladder 410. The gas volume inside the telescopic bladder 410 is adjusted by the main control switch 500, and the gas pressure is evenly transmitted to each sub-control mechanism 200 and the corresponding locking mechanism 300 to achieve synchronous linkage control of the three locking mechanisms 300; the quick-lock mechanism 600, which is set on the top of the tripod 100, is used for quick positioning and locking of the total station base 700.

[0026] In this embodiment, the total station base 700 is placed on top of the tripod 100. The quick-lock mechanism 600 quickly positions and locks the total station base 700, eliminating the need for additional complicated operations and completing the initial setup of the total station base 700. The relative positions of the rotating leg 130 and the extension leg 140 are fixed, and the tripod 100 is in a retracted state. At this time, the telescopic bladder 410 is in a compressed state. When deployment is required, the telescopic bladder 410 is first extended using the master control switch 500, unlocking the fixed state of the extension leg 140. The total station base 700 and the overall height of the device are then raised according to the required working height. The three extension legs 140 rise and fall axially along the rotating leg 130. After the base is raised to the target height, the rotating leg 130 is pulled outward to extend to a preset angle. Then, the relative fixed state of the rotating leg 130 and the extension legs 140 is locked. That is, the gas volume inside the telescopic bladder 410 is compressed by the main control switch 500, so that the gas inside the telescopic bladder 410 generates pressure and is evenly transmitted to the three sub-control mechanisms 200. The three sub-control mechanisms 200 simultaneously receive the pressure signal and drive the compression block 340 of the corresponding locking mechanism 300 to fit tightly against the outer wall of the extension leg 140 and apply uniform pressure, so that the three locking mechanisms 300 can achieve the desired effect. With synchronous locking, the three extension legs 140 and the rotating leg 130 are relatively fixed, and the tripod 100 forms a stable support. If the total station base 700 is not level, the length of the corresponding extension leg 140 needs to be adjusted individually. This can be achieved by depressurizing the corresponding sub-control mechanism 200 and adjusting the clamping force of the compression block 340 individually. After the extension leg 140 is in the correct position, the pressure is restored through the sub-control mechanism 200, driving the compression block 340 to press the extension leg 140, thus locking a single extension leg 140 and ensuring the levelness and stability of the overall support. Then, the formal measurement operation begins. When changing stations after the operation is completed... First, perform the storage operation. Adjust the main control switch 500 in the reverse direction to release the pressure inside the telescopic bladder 410, allowing the gas volume inside the telescopic bladder 410 to return to its initial state. Simultaneously, the three locking mechanisms 300 release the compression block 340. Move the rotating leg 130 inward to complete the storage of the rotating leg 130. Then, retract the extension leg 140 into the rotating leg 130. After completing the storage of the extension leg 140, adjust the main control switch 500 in the forward direction to relock the extension leg 140. Lower the total station base 700 to its initial height, fold up the tripod 100, and move it to the new work point. Repeat the above steps to quickly complete the redeployment.

[0027] In some possible embodiments, such as Figures 2 to 5As shown, the tripod 100 includes: a reference platform 110; three support components evenly distributed along the circumferential direction of the bottom of the reference platform 110, each support component including: a mounting member 120 fixedly mounted on the bottom of the reference platform 110; a mounting compartment 121 mounted on the bottom of the mounting member 120; a rotating shaft 122 rotatably mounted between two adjacent mounting compartments 121; a rotating leg 130 sleeved on the rotating shaft 122 and rotatable around the rotating shaft 122; an extension leg 140 slidably inserted into the rotating leg 130 and rotatable along the axial direction of the rotating leg 130; and a fixed foot 150 fixedly mounted at the end of the extension leg 140 away from the rotating leg 130.

[0028] In this embodiment, in the initial state, the three rotating legs 130 retract inward around the pivot 122, fitting against the bottom of the base platform 110. The extension leg 140 retracts into the interior of the rotating leg 130, and the fixed foot 150 is close to the end of the rotating leg 130, minimizing the overall volume of the tripod 100, facilitating handling, transfer, and storage, and reducing space occupation and collision risks during transportation. After reaching the work point, the operator unlocks the initial fixed state of the extension leg 140 and the rotating leg 130, raises the height of the base platform 110, and extends the extension leg 140 along the axial direction of the rotating leg 130, so that the base is at a suitable working height. At this time, the operator pulls the three rotating legs 130 outward, with each rotating leg 130 forming a uniform angle. At this time, the rotating leg 130 forms a suitable support angle with the ground, and after unfolding, the tripod 100 forms a triangular support structure.

[0029] In some possible embodiments, such as Figures 5 to 9As shown, each sub-control mechanism 200 includes: two fixed clamps 210, symmetrically arranged at the end of the rotating leg 130 away from the rotating shaft 122; a sub-control valve tube 220, arranged between the two fixed clamps 210, with two connecting pipes protruding on both sides of the sub-control valve tube 220, namely a top connecting pipe and a bottom connecting pipe; two main buckles 221, symmetrically arranged on both sides of the sub-control valve tube 220; an end cap 230, threadedly connected to one end of the sub-control valve tube 220; a spring 240, arranged inside the end cap 230; a sub-control valve core 250, slidably arranged in the inner cavity of the sub-control valve tube 220, with a sub-control flow channel 252 opened on the inner side of the sub-control valve core 250 and a circular main control flow channel 251 opened on the outer side, the main control flow channel 251 being selectively connected to the two connecting pipes; and a pressing cover 260, slidably arranged in the sub-control valve tube. 220 is located at the end away from the end cap 230; two secondary buckles 261 are symmetrically arranged on both sides of the press cap 260 and can be engaged with the two main buckles 221; a sealing ring 270 is located at the end of the sub-control valve pipe 220 near the press cap 260; each locking mechanism 300 includes: a compression cylinder 310 connected to the bottom connecting pipe of the sub-control valve pipe 220; two pistons 320 are correspondingly slidably arranged on both sides of the inner cavity of the compression cylinder 310 and can move radially along the compression cylinder 310; two extrusion columns 330 are respectively arranged on each piston 320; two extrusion blocks 340 are respectively arranged at the end of each extrusion column 330 away from the piston 320; two rubber pads 350 are respectively arranged on the inner side of each extrusion block 340, each rubber pad 350 is arc-shaped and can tightly abut against the outer wall of the extension leg 140.

[0030] In this embodiment, when no individual adjustment is performed, the spring 240 is in a compressed state, and the sub-control valve core 250 is in the inner cavity of the sub-control valve tube 220. The pressure in one chamber is balanced with the elastic pressure of the spring 240, and the valve core maintains its initial position. At this time, the arc-shaped main control flow channel 251 on the outside of the sub-control valve core 250 is aligned and connected with the top and bottom connecting pipes of the sub-control valve tube 220, forming a complete pressure transmission path. The gas in the telescopic bladder 410 of the main control mechanism 400 enters the sub-control valve tube 220 and is then injected into the compression cylinder 310 of the locking mechanism 300. The gas pressure in the compression cylinder 310 increases, generating a radial thrust on the pistons 320 on both sides, pushing the pistons 320 to move closer to the extension leg 140. The pistons 320 drive the extrusion column 330 and the extrusion... Block 340 moves synchronously, causing the arc-shaped rubber pad 350 to fit tightly against the outer wall of the extension leg 140. The clamping force fixes the extension leg 140 relative to the rotating leg 130, and all three extension legs 140 lock simultaneously. The tripod 100 provides stable support. When adjusting the length of a single extension leg 140, switch to the individual control mode. First, squeeze the secondary latch 261 to release its engagement with the main latch 221. Then, slide the pressing cover 260 away from the individual control valve tube 220. At this time, the chamber volume on one side of the individual control valve core 250 increases, working in conjunction with the spring 240's restoring elasticity to make the individual control valve core 250 slide away from the spring 240. In this state, the main control flow channel 251 of the individual control valve core 250 and the individual control valve tube 220... The upper and lower connecting pipes of valve 0 are misaligned. At the same time, the sub-control flow channel 252 inside the sub-control valve core 250 is connected to the bottom connecting pipe. At this time, the pressing cover 260 is continuously pulled outward, and the volume of the chamber on one side of the sub-control valve core 250 is further increased, and the air pressure in the chamber decreases. The gas in the compression cylinder 310 enters the chamber through the bottom connecting pipe and the sub-control flow channel 252. The air pressure in the compression cylinder 310 decreases, and the pistons 320 on both sides lose air pressure and move closer to each other, driving the extrusion column 330 and extrusion block 340 to reset synchronously. The rubber pad 350 is disengaged from the outer wall of the extension leg 140, and the limitation on the extension leg 140 is removed. The operator can freely pull the extension leg 140 to adjust its length. After the height of the extension leg 140 is adjusted, the pressing cover 260 is pushed to move closer to the sub-control valve tube 220. The volume of the chamber on the side of the sub-control valve pipe 220 away from the spring 240 gradually decreases, causing the air pressure inside this chamber to rise. This pushes the internal gas back into the compression cylinder 310, where the air pressure gradually recovers. This pushes the pistons 320 on both sides to move towards the extension leg 140 again, causing the compression block 340 and the rubber pad 350 to re-adhere to the outer wall of the extension leg 140, achieving initial locking. As the pressing cover 260 continues to be pushed in, the pressure inside the chamber further increases, pushing the sub-control valve core 250 towards the spring 240, compressing the spring 240 until the elastic force of the spring 240 and the chamber pressure are balanced again. The main latch 221 and the auxiliary latch 261 lock, the sub-control valve core 250 returns to its initial position, and its outer main control flow channel 251 re-aligns and connects with the upper and lower connecting pipes.Restore the main control pressure transmission path.

[0031] In some possible embodiments, such as Figures 10 to 13 As shown, the main control mechanism 400 includes: a telescopic bladder 410, disposed at the bottom of the mounting component 120, forming a sealed inner cavity; a base plate 420, disposed at the bottom of the telescopic bladder 410; two guide pillars 430, respectively disposed on the base plate 420 and correspondingly embedded inside the inner sides of two mounting compartments 121; two guide blocks 440, fixedly disposed in the inner cavities of the mounting compartments 121 corresponding to the two guide pillars 430, the guide pillars 430 being able to rise and fall along the guide blocks 440; and three connecting pipes 450, arranged along the circumference of the telescopic bladder 410, each connecting pipe 450 having one end connected to the telescopic bladder 410. The other end is connected to the top connecting pipe of the sub-control valve pipe 220; the main control switch 500 includes: a knob 510, which is rotatably disposed on the outside of the third mounting compartment 121 other than the mounting compartment 121 where the two guide columns 430 are located; two rotating disks 520, which are coaxially fixedly connected to the knob 510 and built into the corresponding mounting compartment 121; a connecting column 521, which is fixedly disposed between the two rotating disks 520; a lifting rod 530, one end of which is connected to the connecting column 521 and the other end of which is connected to the base plate 420; and a stop block 540, which is disposed on the inner side wall of the corresponding mounting compartment 121 and can abut against the connecting column 521 for limiting.

[0032] In this embodiment, when the telescopic bladder 410 is in its naturally extended state, its internal volume is at its maximum, the internal gas is at normal pressure, the base plate 420 is at its lowest position supported by the telescopic bladder 410, the guide column 430 is at its lowest position along with the base plate 420, the boom 530 is in a vertical state, the knob 510 is vertically downward, and the extension leg 140 can be freely raised and lowered for adjustment. When the extension leg 140 is adjusted to the target height, and it is necessary to lock the relative position of the rotating leg 130 and the extension leg 140, the operator rotates the knob 510, and the rotating disk 520 rotates synchronously with the knob 510, driving the connecting column 521 to perform a circular motion, connecting... During the rotation of column 521, the lifting rod 530 is pulled through the hinge point, gradually lifting the base plate 420 upwards. Under the pulling force of the lifting rod 530, the base plate 420 rises vertically along the guiding direction of the guide column 430 and the guide block 440, simultaneously compressing the top telescopic bladder 410, causing the telescopic bladder 410 to gradually contract from its natural extended state. Its sealed inner cavity volume decreases, the internal gas is compressed, and the air pressure increases. When the knob 510 is continuously rotated until the angle is greater than 180°, the connecting column 521 rotates until it abuts against the stop block 540 on the inner wall of the installation compartment 121. The stop block 540 limits the connection column 521. To prevent the connecting column 521 from rotating further, the continuous tension of the boom 530 and the reaction force of the stop block 540 are balanced, keeping the base plate 420 in its raised position. The telescopic bladder 410 remains in a contracted state, maintaining a stable internal air pressure. The gas is simultaneously transmitted through three connecting pipes 450 evenly distributed around the circumference of the telescopic bladder 410 to the top connecting pipes of the sub-control valve pipes 220 of the three sub-control mechanisms 200, driving the rubber pads 350 to press the extension legs 140, achieving synchronous locking of the three extension legs 140. At this time, the rotating leg 130 unfolds, and the tripod 100 forms a stable support. When the operation is completed, the following steps are required: To retract the extension leg 140, rotate the knob 510 in the opposite direction, causing the rotating disk 520 and the connecting column 521 to rotate in the opposite direction. The connecting column 521 disengages from the stop block 540, and the tension of the boom 530 is gradually released. Under the action of its own elastic restoring force, the telescopic bladder 410 gradually returns to its natural extended state. The internal volume of the telescopic bladder 410 increases, and the internal air pressure decreases. The gas flows back into the telescopic bladder 410 through the connecting pipe 450. The pressure in the sub-control mechanism 200 and the locking mechanism 300 is released simultaneously. The rubber pad 350 of the locking mechanism 300 disengages from the extension leg 140, releasing the locking state.

[0033] In some possible embodiments, such as Figure 14 , Figure 15As shown, the quick-lock mechanism 600 includes: a friction disc 610, which is mounted on the reference platform 110, and a circular through hole is provided in the center of the friction disc 610; a rotating ring 620, which is rotatably mounted on the outer periphery of the reference platform 110; three pressing brackets 630, which are evenly distributed along the circumference of the rotating ring 620; three rubber sleeves 640, which are respectively provided on each pressing bracket 630; a fastening screw 650, which is provided on one of the pressing brackets 630; and a total station base 700, which is placed on the friction disc 610, and the outer side of the total station base 700 has three slots, and each rubber sleeve 640 can be inserted into the corresponding slot as the pressing bracket 630 rotates.

[0034] In this embodiment, the total station base 700 is placed stably on the friction disk 610. The total station base 700 can then be manually moved on the friction disk 610. The center point of the total station base 700 is adjusted using a laser alignment device to ensure precise alignment of the total station's measurement center point with the target point. After adjustment, the outer rotating ring 620 is rotated. The rotating ring 620 drives the three pressing frames 630 to rotate synchronously around the reference platform 110 until each pressing frame 630... Align the rubber sleeve 640 with the corresponding slot on the total station base 700. Use the cantilever tension of the pressing frame 630 to elastically insert the rubber sleeve 640 into the slot. The three rubber sleeves 640 engage simultaneously to achieve circumferential positioning and initial fixation of the total station base 700. At this time, the total station base 700 cannot slide or rotate horizontally. Then tighten the fastening screw 650 on the pressing frame 630 so that the end of the fastening screw 650 abuts against the edge of the reference platform 110, locking the position of the rotating ring 620.

[0035] In some possible embodiments, such as Figure 2 As shown, the bottom of the reference platform 110 has three triangular grooves, and the end of each rotating leg 130 near the reference platform 110 abuts against the corresponding groove.

[0036] In this embodiment, the rotating leg 130 is rotatably connected to the adjacent mounting compartment 121 via the rotating shaft 122. When the operator pulls the rotating leg 130 outward to unfold it, the rotating leg 130 rotates around the rotating shaft 122 until its top end abuts against the corresponding triangular groove. At this time, the groove forms a bidirectional limit on the rotating leg 130, which not only restricts the rotating leg 130 from continuing to unfold outward to avoid the center of gravity of the tripod 100 shifting and the support becoming unstable due to an excessive unfolding angle, but also constrains the radial sway of the rotating leg 130, keeping the rotating leg 130 at a preset support angle, and ensuring that the three rotating legs 130 form a symmetrical triangular support structure after unfolding.

[0037] In some possible embodiments, such as Figure 14 As shown, the friction disk 610 has a plurality of grooves uniformly protruding along the circumferential direction, and each groove extends radially along the friction disk 610.

[0038] In this embodiment, each groove extends radially along the friction disk 610, spreading outward from the edge of the central through hole of the friction disk 610 in a radial distribution. The groove adopts a rigid structure design integrated with the friction disk 610, with a moderate height, which will not affect the stable placement of the total station base 700, and can effectively increase the contact friction with the bottom of the total station base 700.

[0039] When the total station's rapid deployment device is in operation, in the initial state, the tripod 100 is in a retracted state, the three rotating legs 130 retract inward around the pivot 122, fitting against the bottom of the reference platform 110, the extension leg 140 retracts into the interior of the rotating leg 130, and the fixed foot 150 is close to the end of the rotating leg 130, minimizing the overall volume for easy handling, transfer, and storage. At this time, the telescopic bladder 410 of the central control mechanism 400 is in a retracted state, and the internal gas is transmitted to the locking mechanism 300. The compression block 340 fixes the relative position of the extension leg 140 and the rotating leg 130 to prevent slippage during transportation. After arriving at the work site, the total station base 700 is placed on the friction disc 610, and friction... The radial grooves on the surface of disc 610 increase contact friction and prevent the total station base 700 from sliding. The total station base 700 is manually moved and, in conjunction with a laser centering device, the center point is precisely aligned with the target point. Then, rotating the rotating ring 620 drives the three pressing brackets 630 to move synchronously, aligning the rubber sleeve 640 with the outer groove of the total station base 700. The cantilever tension of the pressing brackets 630 allows the rubber sleeve 640 to elastically embed into the groove, achieving circumferential positioning and initial fixation of the total station base 700. Finally, the fastening screw 650 is tightened to abut against the edge of the reference platform 110, locking the position of the rotating ring 620 and completing the rapid fixation of the total station base 700. The operator first rotates the knob 510 in the opposite direction until it is vertical. In the current state, connecting column 521 disengages from stop block 540, lifting rod 530 releases tension, and telescopic bladder 410 returns to its natural extended state under its own elastic force. Internal air pressure decreases, gas flows back in the reverse direction, and the pressure of sub-control mechanism 200 and locking mechanism 300 is released simultaneously. Squeezing block 340 loosens extension leg 140, releasing the fixation between extension leg 140 and rotating leg 130. Then, the reference platform 110 is raised upwards. According to the required working height, the three extension legs 140 are pulled up and down along the axis of rotating leg 130 to initially adjust to the target height, making the reference platform 110 approximately horizontal. After confirming the positions of extension leg 140 and rotating leg 130, the operator holds knob 510 and rotates it more than 180 degrees. °, driving the coaxial rotating disk 520 and connecting column 521 to move in a circular motion. The connecting column 521 lifts the bottom plate 420 upward through the lifting rod 530. The bottom plate 420 rises vertically along the guiding direction of the guide column 430 and the guide block 440, squeezing the telescopic bladder 410 to contract it, reducing the volume of the sealed inner cavity and increasing the gas pressure. The high-pressure gas is transmitted synchronously to the top connecting pipe of the sub-control valve pipe 220 of the three sub-control mechanisms 200 through three evenly distributed connecting pipes 450. At this time, the elastic force generated by the compression of the spring 240 is balanced with the pressure of the chamber on one side of the sub-control valve core 250. The annular main control flow channel 251 on the outside of the sub-control valve core 250 is aligned with the top and bottom connecting pipes to form a complete pressure passage.Gas pressure is transmitted through the control valve pipe 220 to the compression cylinder 310 of the locking mechanism 300, driving the pistons 320 on both sides to move radially. This, in turn, drives the compression block 340 and the arc-shaped rubber pad 350 through the compression column 330, tightly fitting them against the outer wall of the extension leg 140 and applying uniform pressure. This achieves synchronous locking of the three extension legs 140 and the rotating leg 130. After the connecting column 521 rotates to contact the stop block 540, it maintains force balance under the pulling force of the boom 530, keeping the telescopic bladder 410 in a stable contracted state and ensuring locking reliability. At this time, the three rotating legs 130 are pulled outwards, causing them to rotate around the pivot 122 between adjacent mounting compartments 121 until their top ends abut against the triangular groove at the bottom of the reference platform 110. The triangular groove abuts against the rotating leg 130. 30 forms a bidirectional limit, maintaining the preset support angle. The three rotating legs 130 are symmetrically distributed at 120°. The tripod 100 forms a stable triangular support structure. Entering the formal measurement operation, when adjusting the total station's circular level bubble for coarse leveling, if it is necessary to finely adjust a certain extension leg 140, the mode can be switched to: by pressing the secondary buckle 261 to release the engagement with the main buckle 221, the pressing cover 260 is slid away from the sub-control valve pipe 220, causing the sub-control valve core 250 to move away from the spring 240. The volume of the chamber on the side of the sub-control valve core 250 increases, and the spring 240's rebound force maintains the position of the sub-control valve core 250. At this time, the main control flow channel 251 is misaligned with the connecting pipe, and the sub-control flow channel 252 is connected to the bottom connecting pipe. The compression cylinder 310 is in... Gas flows into the chamber, the air pressure drops, and piston 320 resets, causing rubber pad 350 to disengage from extension leg 140. After the limit is released, the height of extension leg 140 can be freely fine-tuned. After fine-tuning, push the pressing cover 260 close to the sub-control valve pipe 220, the chamber volume decreases, the air pressure increases, and the gas flows back to the compression cylinder 310. Piston 320 drives rubber pad 350 to re-adhere to extension leg 140 to achieve initial locking. Continue pushing the pressing cover 260 in, the chamber pressure pushes the sub-control valve core 250 to reset and compress spring 240 until the spring force of spring 240 is balanced with the chamber pressure. The main control flow channel 251 is re-aligned with the connecting pipe, restoring the total control pressure transmission path and completing the secondary locking of a single extension leg 140. This ensures the overall support level and stability, and the formal measurement operation begins. After the operation is completed, loosen the fastening screw 650 in the reverse direction, unlock the rotating ring 620 and rotate it to disengage the rubber sleeve 640 from the slot. Remove the total station base 700, and pull the rotating leg 130 inward to fold it into contact with the reference platform 110. Then, rotate the knob 510 in the reverse direction to disengage the connecting column 521 from the stop block 540, release the tension of the boom 530, and restore the telescopic bladder 410 to its natural extension state. The pressure of the sub-control mechanism 200 and the locking mechanism 300 is released simultaneously, and the squeezing block 340 releases the extension leg 140. Retract the extension leg 140 into the rotating leg 130, and then rotate the knob 510 in the forward direction to fix the extension leg 140 to prevent slippage during transportation. The device is completely restored to its initial retracted state. After transporting it to a new work site, repeat the above process to quickly complete the redeployment.
