Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping auxiliary equipment technology, specifically to a prism support that can be adjusted quickly. Background Technology

[0002] A total station is a high-tech measuring instrument that integrates optics, mechanics, and electronics. It is mainly used to measure various angles and distances. The prism plays a crucial role in the total station's distance measurement process. The prism receives the light signal emitted by the total station and reflects it accurately back to the total station. In this way, the total station can calculate parameters such as phase difference and then calculate the propagation time of the light signal, thereby accurately measuring the distance between the total station and the reflecting prism.

[0003] When using a total station for surveying, it is essential to ensure the prism is level, even on uneven ground. This is because total stations primarily acquire data by measuring light reflection; if the prism is not level, the measurement data will be inaccurate. Specifically, the total station calculates distance and angle by emitting light signals and receiving the reflected signals. If the prism is not level, the angle of the reflected light will change, thus affecting the accuracy of the measurement.

[0004] Due to the complex terrain environment during surveying, prisms need to be correctly placed on the measurement points. Typically, prisms are installed on the ground using auxiliary supports or by manual support. Prisms installed on supports are difficult to keep vertical and need to be adjusted using the attitude adjustment mechanism on the supports.

[0005] Existing technology discloses a total station prism support with application number CN202121162031.9. This support uses a fine-tuning mechanism on the legs to adjust the length of the legs, thereby leveling the prism and ensuring accurate data measurement. However, this method requires changing the length and unfolding angle of the legs to ensure the prism is perpendicular to the horizontal plane. The existing adjustment mechanism is overly cumbersome, resulting in poor prism adjustment efficiency. Utility Model Content

[0006] The purpose of this invention is to solve the technical problem of poor prism adjustment efficiency caused by the attitude adjustment structure on the support frame for placing a prism. It provides a prism bracket for rapid adjustment, enabling multi-free and rapid adjustment of the prism by setting a flexible guide tube between the prism and the support frame. The main concept is as follows:

[0007] A quick-adjustment prism bracket includes a mounting frame, a worktable, and a universal flexible guide hose. The worktable is used to mount the prism that receives optical signals from a total station. The worktable and the prism move synchronously. The mounting frame and the worktable are connected by the universal flexible guide hose, which is used for multi-degree-of-freedom adjustment of the worktable. This design allows for rapid adjustment of the prism to a vertical position via the universal flexible guide hose.

[0008] Preferably, the mounting bracket includes a mounting base and three legs. The mounting base has three positioning hinges along its circumference, and the legs are movably connected to the mounting base via the positioning hinges. By unfolding the legs to form a certain angle, the mounting bracket provides stable support for the prism.

[0009] Preferably, multiple universal flexible guide hoses are provided between the mounting frame and the worktable, and the multiple universal flexible guide hoses are evenly distributed circumferentially on the mounting frame and the worktable. Providing multiple universal flexible guide hoses can better support the worktable, and the installation positions of the universal flexible guide hoses are evenly distributed on the side of the axis.

[0010] Preferably, the universal shaping hose includes a metal wire and a rubber layer, with the rubber layer covering the outside of the metal wire. The rubber layer covering the metal wire enhances its support strength.

[0011] Preferably, the worktable is installed below the prism, with the worktable and the receiving surface of the prism perpendicular to each other. The worktable is also equipped with a first level, which moves synchronously with the worktable and is used to detect the levelness of the worktable. When adjusting the worktable using the universal positioning hose, observing the first level can visually reflect whether the synchronously adjusted prism has been adjusted to a vertical state. If the first level measures that the worktable is completely level, then the receiving surface of the prism is in a vertical state.

[0012] The second aspect of this invention aims to solve the technical problem of inaccurate measurement accuracy caused by deviations in the actual measurement position of the prism and mounting bracket acting on a horizontal surface after adjustment of the universal shaping hose. Further, it includes a positioning component comprising a laser locator and a reference point. The laser locator is installed below the worktable, with its laser beam coinciding with the midpoint of the prism's receiving surface. The reference point is set at the ground measurement position. When the laser beam of the laser locator vertically coincides with the reference point, the prism is located at the actual measurement position. This solution adjusts the measurement position deviation by aligning the laser beam emitted by the laser locator with the reference point. The reference point can be marked by placing a reference block or drawing a point to facilitate observation of whether the laser beam emitted by the laser locator coincides with the reference point. When the laser beam coincides with the reference point, the prism is adjusted to an accurate vertical position above the ground measurement position, improving the measurement accuracy between the total station and the prism.

[0013] The third aspect of this invention aims to solve the technical problem of difficulty in measuring the height of the workbench after it has changed from its position relative to the ground measurement location due to the universal shaping hose. Furthermore, the laser locator is a laser distance measuring instrument, used to measure the distance between the workbench and a reference point. The laser distance measuring instrument can measure short distances. It not only emits a laser beam to observe its alignment with the reference point, but also accurately measures the height between the prism and the reference point on the ground using laser ranging principles. This allows for rapid height measurement of the prism mounted on the workbench, even after irregular adjustments via the universal shaping hose.

[0014] Preferably, the mounting base has a clearance hole in the middle position, which is used for the laser beam emitted by the laser positioner. When the mounting base has a clearance hole in the middle position, the laser beam emitted by the laser positioner can pass through the clearance hole and be compared with the reference point when the bracket is on a horizontal or inclined ground. Furthermore, when the inclination angle of the ground is too large, by adjusting the overall position of the bracket so that the clearance hole surrounds the reference point in the vertical projection, the laser positioner can be positioned with slight adjustments in the horizontal direction to the reference point.

[0015] The fourth aspect of this utility model aims to solve the technical problem of measurement failure caused by obstructions between the prism and the total station during measurement, which block the laser emitted by the total station. Further, the support includes a first support and a second support. The first support has a sliding cavity to accommodate the second support, and the second support is used to adjust its height. This solution adjusts the overall height of the support by sliding the second support within the sliding cavity of the first support, thereby avoiding obstruction of the prism support on the ground due to insufficient height when receiving the laser signal from the total station, thus improving the flexibility of the prism support.

[0016] The beneficial effects of this utility model are as follows:

[0017] The prism is adjusted using a universal shaping hose, allowing it to be quickly adjusted to a vertical position. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0023] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0024] Example 1:

[0025] like Figures 1-2 As shown, this embodiment provides a quick-adjustment prism bracket, including a mounting frame 1, a worktable 2, and a universal shaping hose 3. The worktable 2 is used to install the prism 4 that receives the optical signal from the total station. The worktable 2 and the prism 4 move synchronously. The mounting frame 1 and the worktable 2 are connected by the universal shaping hose 3, which is used to adjust the worktable 2 with multiple degrees of freedom.

[0026] In this embodiment, the worktable 2 is adjusted to a horizontal state by using the universal shaping hose 3, so that the prism 4 can be quickly adjusted to a vertical state.

[0027] Mounting bracket 1 includes mounting base 12 and three legs 11. Mounting base 12 has three positioning hinges along the circumferential direction. The legs 11 are movably connected to mounting base 12 through the positioning hinges.

[0028] By unfolding the legs 11 to form a certain angle, the mounting bracket 1 provides stable support for the prism 4.

[0029] The three support legs 11, when fully extended, have the same tilt angle, causing the points of contact between the three support legs 11 on the ground to form an equilateral triangle. For example... Figure 3 As shown, in this embodiment, the end of the support leg 11 that contacts the ground is set in a conical shape.

[0030] Example 2:

[0031] like Figures 1-3 As shown, in this embodiment, multiple universal flexible guide hoses 3 are provided between the mounting frame 1 and the worktable 2. The multiple universal flexible guide hoses 3 are evenly distributed circumferentially on the mounting frame 1 and the worktable 2. Providing multiple universal flexible guide hoses 3 can better support the worktable 2, and the even distribution of the installation positions of the universal flexible guide hoses 3 circumferentially around the axis allows for the reservation of positions for installing positioning components and positioning holes at the axis positions of the mounting frame 1 and the worktable 2.

[0032] The universal shaping hose 3 includes a metal wire and a rubber layer, with the rubber layer covering the outside of the metal wire.

[0033] The metal wire is made of metal with good deformability. The metal wire can be bent freely within a certain range and maintain the required position and direction. The outside of the metal wire is covered with a rubber layer. The elastic properties of the rubber make the metal wire less likely to break when bent, while maintaining good flexibility and also improving the support of the metal wire.

[0034] The universal shaping hose achieves multi-directional movement and shaping through its internal metal wires and rubber layers. During operation, the universal shaping hose 3 will withstand the pressure and physical stress from the worktable 2. Through the combined action of the inner and outer layers, the universal shaping hose 3 maintains its stability at different radii of curvature and can withstand high temperature, high pressure, high flow rate and high intensity impact.

[0035] The metal wires of the universal shaping hose 3 form a reinforcing layer. The reinforcing layer is usually made of steel wire strand or steel strip, which is woven into a spiral shape and fixed inside the rubber layer to form a spring-like structure. This structure allows the universal shaping hose 3 to freely expand and contract when subjected to torsional force, withstand large torsional forces, and achieve the shaping effect.

[0036] In this embodiment, the worktable 2 is installed below the prism 4, and the receiving surfaces of the worktable 2 and the prism 4 are perpendicular to each other. The worktable 2 is also equipped with a first level 5, which moves synchronously with the worktable 2. The first level 5 is used to detect the levelness of the worktable 2. When the worktable 2 is adjusted through the universal positioning hose, the first level 5 can be observed to visually reflect whether the synchronously adjusted prism 4 has been adjusted to a vertical state. If the first level 5 measures that the worktable 2 is completely level, then the receiving surface of the prism 4 is in a vertical state.

[0037] In one embodiment, in order to facilitate the leveling of the workbench 2, auxiliary handles can be provided on both sides of the workbench 2. The auxiliary handles enable the operator to better apply force to the workbench 2, and the universal shaping hose 3 connected to the bottom of the workbench 2 automatically adjusts to a suitable shape and provides stable support under the force applied by the workbench 2.

[0038] The number of universal positioning hoses 3 can be adjusted according to the actual situation. In this embodiment, multiple installation joints for connecting universal positioning hoses are set at the bottom of the workbench 2 and the top edge of the mounting base 12. The number of universal positioning hoses 3 is selected according to the actual situation.

[0039] Example 3:

[0040] like Figures 1-2 As shown, this embodiment also includes a positioning component, which includes a laser locator 6 and a reference point 7. The laser locator 6 is installed below the workbench 2. The laser beam of the laser locator 6 coincides with the middle position of the receiving surface of the prism 4. The reference point 7 is set at the ground measurement position. When the laser beam of the laser locator 6 and the reference point 7 are vertically aligned, the prism 4 is located at the actual measurement position.

[0041] When the workbench 2 remains level under the measurement of the level instrument 5, the laser beam emitted by the laser locator 6 coincides with the reference point 7, thereby adjusting the prism 4 to the accurate installation position of the mounting bracket 1. In this embodiment, the measurement position deviation is adjusted by aligning the laser beam emitted by the laser locator 6 with the reference point 7. The reference point 7 can be marked by placing reference blocks or drawing points to facilitate observation of whether the laser beam emitted by the laser locator 6 coincides with the reference point 7. When the laser beam coincides with the reference point, the prism 4 is adjusted to the accurate vertical position above the ground measurement position, improving the measurement accuracy between the total station and the prism 4.

[0042] In this embodiment, the level 5 is a bubble level. The bubble level includes a level tube and a liquid inside the level tube. The liquid inside the level tube is ether or alcohol, and a small air bubble is left inside. The part of the level without liquid is usually called the level bubble, which is always located at the highest point in the tube. The inner wall of the level tube is a curved surface with a certain radius of curvature. When the level is tilted, the level bubble in the level tube moves towards the higher end of the level. When the level bubble is located in the middle of the level tube, the level is horizontal, thus making the installation reference surface of the level horizontal.

[0043] Example 4:

[0044] like Figures 1-2As shown, the laser locator 6 in this embodiment is a laser distance measuring instrument, used to measure the distance between the workbench 2 and the reference point 7. When performing total station distance measurement, the instrument height and prism height are essential parameters. By accurately measuring the prism height, the height difference of the prism can be taken into account during the measurement process, thus making the total station's measurement results for the prism more accurate.

[0045] This embodiment uses a laser distance measuring instrument to measure the length of short distances. The laser distance measuring instrument can not only emit a laser beam to observe the overlap and positioning of the laser with the reference point, but also accurately measure the height between the prism 4 and the reference point 7 located on the measurement ground through the laser ranging principle. This allows the prism 4 set on the workbench 2 to quickly measure its height even after irregular adjustment by the universal shaping hose 3.

[0046] In this embodiment, the mounting base 12 has a clearance hole 8 in the middle position. The clearance hole 8 is used for the laser beam emitted by the laser positioner 6. When the mounting base 12 has the clearance hole 8 in the middle position, the laser beam emitted by the laser positioner 6 can pass through the clearance hole 8 and be compared with the reference point 7, whether the prism bracket is on a horizontal or inclined surface. Furthermore, if the inclination angle of the ground is too large, by adjusting the overall position of the bracket, the clearance hole can surround the reference point 7 within its vertical projection, allowing the laser positioner 6 to be positioned with the reference point 7 after minor horizontal adjustments. Figure 2 As shown, the receiving surface of prism 4 points in the direction of the inclination of the ground at the measurement position. After the worktable 2 is adjusted by the universal positioning hose 3, the worktable 2 will tilt upwards. At the same time, the mounting bracket of the bracket will tilt downwards. The worktable 2 of the prism bracket, which is designed for quick adjustment, can adjust the center of gravity of the entire bracket, making the bracket more stable on the inclined ground at the measurement position.

[0047] Example 5:

[0048] like Figures 1-3 As shown, the support leg 11 in this embodiment includes a first support leg 111 and a second support leg 112. The first support leg 111 has a sliding cavity 113 for accommodating the second support leg 112. The second support leg 112 is used to adjust the height of the support leg 11.

[0049] When the support is placed on an uneven ground at the measurement position, after the workbench 2 is quickly leveled by the universal positioning hose 3, in order to make the laser beam emitted vertically downward by the laser positioner 6 below the prism 4 on the workbench 2 coincide with the reference point 7 on the measurement ground.

[0050] Since the mounting base 12 of the prism bracket, which is vertically installed on the inclined ground, is located in the downward tilt direction, the clearance hole 8 of the mounting base 12 no longer surrounds the reference point 7 of the actual measurement position. By adjusting the prism bracket in the upward tilt direction, the clearance hole 8 of the mounting base 12 can be made to surround the reference point of the actual measurement position again, thus correcting the installation position of the prism bracket's legs 11 at the actual measurement position.

[0051] like Figure 3 As shown, in order to enable the support leg 11 to be quickly adjusted in height each time, this embodiment quickly controls the sliding distance of the second support leg 112 in the sliding cavity 113 of the first support leg 111 each time.

[0052] Since one of the purposes of extending the support leg 11 in this embodiment is to avoid blocking the emission of the laser positioner 6 when the bracket is tilted, the sliding length of the sliding cavity 113 in this embodiment is such that when the bracket is tilted, the extension of the second support leg 112 can just avoid the extension of the mounting base 12.

[0053] The support leg 11 also includes a fastener, which enables the second support leg 112 to act stably against the first support leg 111, thus ensuring stable support of the support leg 11. The fastener is a fastening screw, and a threaded hole is provided on the side of the first support leg 111 so that the fastening screw is threadedly connected to the first support leg 111. The output end of the fastening screw abuts against the second support leg 112, and the second support leg 112 is kept stably positioned by the fastening screw pressing against it.

[0054] In this embodiment, the sliding cavity 113 is a circular groove. The second support leg 112 is positioned at its end within the sliding cavity 113, and the second support leg 112 and the positioning end are fixedly connected by welding or integral machining. An annular groove is formed in the middle of the outer contour surface of the positioning end, and the cross-section of the annular groove is semi-circular. The outer diameter of the positioning end is larger than the outer diameter of the second support leg 112, and the inner diameter of the sliding cavity 113 is the same as the outer diameter of the positioning end. The sliding cavity 113 and the positioning end slide in fit.

[0055] A retaining ring is provided at the output end of the sliding cavity. The retaining ring serves two purposes: firstly, it prevents the positioning end from sliding out of the positioning groove; secondly, it positions the positioning end against the installation position of the fastener.

[0056] In this embodiment, the output end of the fastening screw has an arc-shaped ball head structure. This arc-shaped ball head structure not only minimizes damage to the contact point of the second leg 112 through point contact, but also allows it to cooperate with the annular groove of the positioning end. The maximum outer diameter of the arc-shaped ball head structure is smaller than the inner diameter of the annular groove section of the positioning end. The threaded hole on the first leg 111 is positioned so that the annular groove points to the position when the positioning end abuts against the retaining ring, allowing the positioning end to be precisely inserted into the annular groove of the positioning end via the retaining ring. This allows the second leg 112 to directly extend outward to the retaining ring position during adjustment, securing it with the fastener. This ensures that the extension lengths of the three legs 11 are consistent, eliminating the need for additional length control and adjustment.

[0057] However, the fastening screw in this embodiment has a certain length and can also act on the outer wall of the second leg 112, so that the second leg 112 can also be adjusted to a custom extension length. A scale can be marked on the outer wall of the second leg 112 to make the extension length of the second leg 112 visible.

[0058] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
