Description

Technical Field

[0001] This invention relates to the field of total station installation technology, and more specifically to a total station installation and adjustment mechanism. Background Technology

[0002] In existing technology, total stations are typically mounted on a tripod using bolts. Since leveling the tripod relies primarily on adjusting the extension lengths of its three legs, this process is cumbersome and time-consuming. Furthermore, because the total station is bolted to the tripod, adjusting the instrument's center point to align with the measurement station requires loosening the bolts, manually moving the total station, and then tightening them again – a process that is not only inconvenient but also inefficient. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a total station installation and adjustment mechanism to solve the problems of cumbersome horizontal adjustment operation of total station on tripod and low adjustment efficiency caused by repeated disassembly and reassembly of bolts when centering the measurement station.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A total station mounting and adjustment mechanism, mounted on a tripod, includes:

[0006] The fixed plate has a sliding support plate for supporting the total station. The fixed plate has a through hole in the center and the support plate has a through groove in the middle.

[0007] Multiple first adjustment components are disposed between the tripod and the fixed plate, and are used to adjust the angle of the fixed plate relative to the tripod so that the total station remains horizontal;

[0008] The second adjustment component is located on the fixed plate and connected to the support plate, and is used to adjust the position of the support plate in the X-axis direction so that the center of the total station corresponds to the station point.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. By setting multiple first adjustment components between the tripod and the fixed plate, the angle of the fixed plate can be easily adjusted without repeatedly extending and retracting the tripod legs, thus achieving rapid leveling of the total station; at the same time, by driving the bearing plate to slide in the X-axis direction through the second adjustment component, the center of the total station can be adjusted to be aligned with the measurement station, which effectively simplifies the operation steps and improves the overall setup and adjustment efficiency of the surveying operation.

[0011] Furthermore, the first adjustment assembly includes a connecting rod, a movable seat, and a first adjustment screw. One end of the connecting rod is rotatably connected to the bottom of the fixed plate, and the other end is rotatably connected to the movable seat. The fixed plate is provided with two spaced-apart fixed blocks. The first adjustment screw is rotatably installed between the two fixed blocks, and the movable seat is threadedly connected to the first adjustment screw.

[0012] Furthermore, the bottom of the movable seat is provided with a limiting block, and the top of the tripod is provided with a limiting groove for the limiting block to slide and engage.

[0013] Furthermore, the second adjustment assembly includes a fixed seat disposed on the fixed plate and a second adjustment screw rotatably disposed on the fixed seat. One end of the bearing plate is provided with a slide block, which is slidably disposed within the fixed seat and threadedly connected to the second adjustment screw.

[0014] Furthermore, the fixing seat has a groove, and the slide block is slidably engaged with the groove.

[0015] Furthermore, the fixed plate is provided with a support seat on the other side of the support plate, and the support plate is slidably disposed on the support seat.

[0016] Furthermore, it also includes two mounting plates, which are spaced apart at the bottom of the total station, and each mounting plate is provided with a mounting seat; the bearing plate is symmetrically provided with two support seats along the Y-axis direction perpendicular to the X-axis, and the two mounting seats are slidably disposed on the two support seats in a one-to-one correspondence; the mounting seats are also provided with fasteners, which are used to fix the mounting seats to the support seats.

[0017] Furthermore, the support base has a slot along its length, and the mounting base is slidably engaged in the slot; the fastener is a fastening bolt, which is threadedly connected to the mounting base, and its end abuts against the slot.

[0018] Furthermore, the slot extends from one end of the support base to the other end.

[0019] Furthermore, the mounting plate has mounting holes. Attached Figure Description

[0034] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions of this invention are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0036] like Figure 1-6As shown in the figure, this embodiment of the invention proposes a total station installation and adjustment mechanism, which is installed on a tripod 200 and includes: a fixed plate 1, on which a support plate 2 for supporting the total station 100 is slidably provided, the fixed plate 1 having a through hole 101 in the center, and the support plate 2 having a through groove 201 in the middle; a plurality of first adjustment components 3, disposed between the tripod 200 and the fixed plate 1, for adjusting the angle of the fixed plate 1 relative to the tripod 200 so that the total station 100 remains horizontal; and a second adjustment component 4, disposed on the fixed plate 1 and connected to the support plate 2, for adjusting the position of the support plate 2 in the X-axis direction so that the center of the total station 100 corresponds to the station point.

[0037] Specifically, in this embodiment, the number of first adjustment components 3 is set to three, and the three first adjustment components 3 are evenly distributed along the circumference of the fixed disk 1 to achieve precise adjustment of the angle of the fixed disk 1.

[0038] In actual use, the total station 100 is first pre-installed on the support plate 2. Then, the operator observes the circular bubble on the total station 100 and adjusts the corresponding first adjustment component 3 according to the direction and degree of the circular bubble's offset until the circular bubble is centered. At this time, the total station 100 is in a horizontal state.

[0039] It should be noted that in the traditional operating method, the operator usually first fixes the total station 100 to the tripod 200 with bolts, then moves the tripod 200 to align the center of the total station 100 with the survey station, and then adjusts the extension length of each leg of the tripod 200 to achieve leveling. However, because the height of each leg changes during the leveling process, the center of the total station 100, which was originally aligned, will shift. At this time, the operator needs to loosen the bolts and manually move the total station 100 to re-align it, repeating this process repeatedly, which is extremely cumbersome.

[0040] Therefore, in the technical solution of this invention, after the total station 100 is installed on the support plate 2, it is first leveled using the first adjustment component 3. This process does not require extending or retracting the legs of the tripod 200; simply adjusting the corresponding first adjustment component 3 is sufficient to tilt the fixed plate 1 and the total station 100 to a horizontal position. After leveling, the support plate 2 is then finely adjusted in the X-axis direction using the second adjustment component 4, and the laser emitted by the total station 100 is observed until the laser point is precisely aligned with the measurement station. Throughout the adjustment process, the operator does not need to loosen or tighten any bolts or move the tripod 200, greatly simplifying the operation.

[0041] The through hole 101 in the center of the fixed plate 1 and the through groove 201 in the middle of the bearing plate 2 are designed to ensure that the laser or line of sight emitted by the total station 100 can pass through without obstruction to reach the measurement station, thus ensuring the centering accuracy.

[0042] Specifically, such as Figure 3-4 As shown, in this embodiment of the invention, the first adjusting component 3 includes a connecting rod 31, a movable seat 32, and a first adjusting screw 33. One end of the connecting rod 31 is rotatably connected to the bottom of the fixed disk 1, and the other end is rotatably connected to the movable seat 32. The fixed disk 1 is provided with two spaced-apart fixed blocks 34. The first adjusting screw 33 is rotatably installed between the two fixed blocks 34, and the movable seat 32 is threadedly connected to the first adjusting screw 33.

[0043] In practical use, the operator first observes the circular bubble on the total station 100, and determines which side of the fixed disk 1 is too low or too high based on the direction of the bubble's deviation. Then, the operator rotates the corresponding first adjusting screw 33. Since the movable seat 32 is threadedly engaged with the first adjusting screw 33, and the movable seat 32 is connected to the bottom of the fixed disk 1 via a connecting rod 31, rotating the first adjusting screw 33 causes the movable seat 32 to move axially along the first adjusting screw 33, driving the lower end of the connecting rod 31 to move accordingly. The upper end of the connecting rod 31 then pushes the corresponding part of the fixed disk 1 up or down, thereby adjusting the angle of the fixed disk 1. Once the circular bubble is centered, the leveling operation is complete.

[0044] Furthermore, the bottom of the movable seat 32 is provided with a limiting block 321, and the top of the tripod 200 is provided with a limiting groove 210 for the limiting block 321 to slide and engage. When the operator rotates the first adjusting screw 33, the movable seat 32, under the constraint of the limiting block 321 and the limiting groove 210, can only slide along the axial direction of the first adjusting screw 33, without deflection or shaking, ensuring the stability and straightness of the movement trajectory of the movable seat 32, thereby ensuring that the adjustment of the angle of the fixed plate 1 by the connecting rod 31 is more precise and reliable. At the same time, the engaging cooperation between the limiting block 321 and the limiting groove 210 also plays a role in limiting and preventing the movable seat 32 from unscrewing and falling off the first adjusting screw 33, improving the safety and reliability during use.

[0045] Specifically, such as Figure 5-6 As shown, in this embodiment of the invention, the second adjustment component 4 includes a fixed seat 41 disposed on the fixed plate 1 and a second adjustment screw 42 rotatably disposed on the fixed seat 41. One end of the bearing plate 2 is provided with a slide 21, which is slidably disposed in the fixed seat 41 and threadedly connected to the second adjustment screw 42.

[0046] In practical use, after completing the leveling operation through the first adjustment component 3, the operator activates the laser centering function of the total station 100 and observes the position of the laser point at the measurement station. If there is a deviation between the laser point and the center of the measurement station, the operator only needs to rotate the second adjustment screw 42. Since the slide 21 is threadedly engaged with the second adjustment screw 42, and the slide 21 is slidably set in the fixed seat 41 and cannot rotate with the second adjustment screw 42, the rotational motion of the second adjustment screw 42 is converted into the linear motion of the slide 21 along its axial direction. The slide 21 drives the bearing plate 2 and the total station 100 on the bearing plate 2 to move as a whole in the X-axis direction until the laser point is precisely aligned with the center of the measurement station, thus completing the centering operation.

[0047] Furthermore, the fixed base 41 has a groove 411, and the slide 21 is slidably engaged with the groove 411. When the operator rotates the second adjusting screw 42, the slide 21, guided and constrained by the groove 411, can only slide along the axial direction of the second adjusting screw 42, effectively preventing the slide 21 from deflecting or shaking during sliding, ensuring the linearity and stability of the movement of the slide 21 and the support plate 2. At the same time, the engagement between the groove 411 and the slide 21 also ensures that the support plate 2 maintains the correct posture when bearing the weight of the total station 100, without tilting, so that the second adjusting screw 42 only bears the axial force and is not subjected to the lateral force from the slider, thereby reducing the bending stress of the second adjusting screw 42.

[0048] Furthermore, a support seat 11 is provided on the other side of the fixed plate 1 corresponding to the support plate 2, and the support plate 2 is slidably mounted on the support seat 11. Through this arrangement, one end of the support plate 2 is slidably engaged with the fixed seat 41 via the slide block 21 and driven by the second adjusting screw 42, while the other end is slidably supported by the support seat 11. This ensures that both ends of the support plate 2 are effectively constrained and supported when moving in the X-axis direction, avoiding problems such as one end being suspended, tilted, or stuck due to excessive span or uneven force on the support plate 2, thus guaranteeing the smoothness and stability of the sliding process of the support plate 2. Simultaneously, the support seat 11 and the fixed seat 41 together form a two-point support guide for the support plate 2, ensuring that the support plate 2 always moves in a straight line and maintains a horizontal posture during adjustment, preventing tilting due to the weight of the support plate 2 itself or the total station 100, thereby ensuring the accuracy of the centering adjustment.

[0049] Based on the above solutions, such as Figure 5As shown, in this embodiment of the invention, two mounting plates 5 are also included. The two mounting plates 5 are spaced apart at the bottom of the total station 100, and each mounting plate 5 is provided with a mounting seat 51. The bearing plate 2 is symmetrically provided with two support seats 22 along the Y-axis direction perpendicular to the X-axis. The two mounting seats 51 are slidably disposed on the two support seats 22 in a one-to-one correspondence. The mounting seats 51 are also provided with fasteners 52, which are used to fix the mounting seats 51 to the support seats 22.

[0050] Specifically, this solution enables the total station 100 to have position adjustment capability in the Y-axis direction (i.e., another horizontal direction perpendicular to the X-axis) through the sliding engagement of the mounting base 51 and the support base 22. This allows the centering adjustment of the total station 100 to be extended to two mutually perpendicular directions, the X-axis and the Y-axis, realizing two-dimensional precise adjustment in the horizontal plane. This can adapt to the offset requirements of different station positions and has a wider range of applications.

[0051] In actual use, the operator first loosens the fastener 52 so that the mounting base 51 can slide freely on the support base 22. Then, according to the actual position of the measuring station, the operator pushes the total station 100 to the required position along the Y-axis. Then, the operator tightens the fastener 52 to fix the mounting base 51 on the support base 22, thus completing the positioning of the total station 100 in the Y-axis direction.

[0052] Specifically, such as Figure 6 As shown in this embodiment of the invention, the support base 22 has a slot 221 along its length, and the mounting base 51 is slidably engaged with the slot 221; the fastener 52 is a fastening bolt, which is threadedly connected to the mounting base 51, and its end abuts against the slot 221. When it is necessary to adjust the position of the total station 100 in the Y-axis direction, the operator only needs to loosen the fastening bolt so that the end of the fastening bolt disengages from the bottom wall of the slot 221. At this time, the mounting base 51 can slide freely along the slot 221 to the target position; after the position is adjusted to the correct position, tighten the fastening bolt so that its end abuts against the bottom wall of the slot 221, and the mounting base 51 can be reliably fixed on the support base 22.

[0053] Furthermore, to facilitate the installation and disassembly of the total station 100, the slot 221 extends from one end of the support base 22 to the other. During installation, the operator simply aligns the mounting base 51 with the opening of the slot 221 at the end of the support base 22 and pushes it horizontally along the Y-axis to complete the installation. During disassembly, the mounting base 51 is slid along the slot 221 to the end opening and then pulled out to remove the total station 100. Simultaneously, the mounting plate 5 has mounting holes 53. Specifically, mounting holes 53 are provided on both sides of the mounting plate 5; by passing bolts through the mounting holes 53 and screwing them into the connecting holes at the bottom of the total station 100 and tightening them, the total station 100 can be firmly fixed to the two mounting plates 5, thereby achieving the fixed assembly of the total station 100.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
