It is widely used in precision engineering surveys and deformation monitoring, such as those involved in large-scale above-ground construction and underground tunnel construction. Due to their high accuracy, direct data reading during the measurement process, and portability, total stations are widely used in shipbuilding. However, in actual use, the on-site construction environment and confined spaces often make it difficult to obtain the required data, necessitating the use of auxiliary tools to complete the measurement.

[0030] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0031] Please refer to Figure 1In an embodiment of the present application, there is provided an auxiliary measurement tool 100 based on a total station, comprising at least one target plate 140, a target adjustment rod 130, an angle adjustment rod 120 and a fixing part 110. The structure is simple, easy to carry and more flexible for measurement. The number of target plates 140 can be determined according to needs. If the two-point measurement function of the total station 200 is required, two target plates 140 can be set. The target plate 140 is used for measurement and positioning of the total station 200. The target plate 140 is in the shape of a plate, and one or both sides thereof are marked with a positioning point or a positioning cross for positioning, so as to facilitate the determination of the position when the total station 200 is measuring; the target adjustment rod 130 is connected to the target plate 140 and is used to adjust the position of the target plate 140. The target adjustment rod 130 is in the shape of a plate, and is used to adjust the position of the target plate 140. The target plate 140 is rod-shaped, and is fixed on the target adjustment rod 130. It can be located at the end. The fixing method can be plug-in fixing, screw connection fixing, or other conventional fixing methods. The position of the target plate 140 can be adjusted by the target adjustment rod 130; the angle adjustment rod 120 has a certain length and can extend a distance outward from the to-be-measured position, so as to avoid the position that is shielded when the total station 200 is measuring. The angle adjustment rod 120 is rotatably connected to the target adjustment rod 130, such as the angle adjustment rod 120. The end of the angle adjustment rod 120 is provided with a steering joint. The steering joint is such as a conventional rotary joint. The opposite ends of the joint have through holes. The target adjustment rod 130 is inserted into the through holes and fixed. The end of the steering joint perpendicular to the target adjustment rod 130 is clamped in the end of the angle adjustment rod 120, so that the target adjustment rod 130 can rotate relative to the angle adjustment rod 120, thereby adjusting the position of the target plate 140; the fixing member 110 is used to be detachably connected to the part to be tested. The fixing member 110 can be detachably connected to the part to be tested in a variety of ways. For example, the fixing member 110 uses a magnet, and the part to be tested is a magnetic material of steel, and a detachable connection is achieved by magnetic connection. For example, the fixing member 110 uses an iron block, and a strong glue is attached to its bottom, and a detachable connection is achieved by adhesion. The fixing member 110 is fixedly connected to the angle adjustment rod 120. For example, the fixing member 110 is provided with an internal threaded hole, and one end of the angle adjustment rod 120 is matched and connected to the fixing member 110 through the internal threaded hole.

[0032] The total station 200 of the prior art is a fixed measuring rod that cannot be flexibly adjusted as needed. In order to measure the target, it is necessary to carry measuring rods of different lengths for assistance, which makes the measurement work inconvenient. However, the present application no longer requires carrying measuring rods of different lengths for assistance. It is only necessary to temporarily fix the fixing member 110 to the place to be measured through a detachable connection, and then extend a displacement from the place to be measured to the outside through the angle adjustment member. The target adjustment rod 130 is rotatably connected to the angle adjustment rod 120 to adjust the relative angle and position of the target adjustment rod 130, thereby achieving the adjustment of the position of the target plate 140. The target plate 140 can be used as a positioning device for the total station 200 during measurement. The total station 200 has a measurement point positioning function. The position of the target in the coordinate system of the total station 200 can be determined by a two-point measurement method, and the measurement coordinates can be obtained. In this way, the target can be flexibly adjusted according to the needs of on-site measurement, and the measurement can be completed quickly, reducing the influence of the on-site measurement environment and expanding the scope of use of the total station 200.

[0033] Since the existing total station 200 uses the "two-point measurement" of the precision management software to adjust the distance value of the two targets and the distance value between the target and the rod tip when measuring the target, and the target on the existing fixed measuring rod cannot be moved, the "two-point measurement" function of the current total station 200 precision management software is greatly limited. After adopting the present application, the target plate 140 can be adjusted in position through the target adjustment rod 130 and the angle adjustment rod 120, so it can more flexibly adapt to the two-point measurement of the total station 200, which has a very great advantage over fixed targets; and the present application has formed a product, has been fully verified and applied in practice, and has played a good auxiliary role in the measurement of the total station 200.

[0034] In some embodiments, the fixing member 110 is a block magnet, which is used to be detachably connected to the magnetic part to be measured by magnetic attraction. Generally speaking, it is applied to the field of ships. The hull itself is made of steel, and the magnet can be easily temporarily connected to various parts of the hull. The magnet can be a magnet with strong magnetism, such as a strong magnet, a neodymium magnet, etc. The fixing member 110 can be temporarily connected to the part to be measured by magnetic connection. After the fixing member 110 is temporarily fixed, under the action of the strong magnetic force, the entire auxiliary measurement tool 100 can also maintain stability. The size of the fixing member 110 used can be determined according to the weight of the target plate 140, the target adjustment rod 130 and the angle adjustment rod 120 to ensure that the fixing member 110 has sufficient magnetic force.

[0035] Please refer to Figure 2In some embodiments, the target adjustment rod 130 includes a first telescopic member 131 and a second telescopic member 132. The first telescopic member 131 or the second telescopic member 132 is rotatably connected to the angle adjustment rod 120. For example, the first telescopic member 131 and the angle adjustment rod 120 are connected through a steering joint, or the second telescopic member 132 and the angle adjustment rod 120 are connected through a steering joint. At least one of the first telescopic member 131 and the second telescopic member 132 is connected to a target plate 140. The target plate 140 is arranged as described above. The connection mode of the target adjustment rod 130 is such that the first telescopic member 131 can adjust the relative position and lock with respect to the second telescopic member 132. For example, the first telescopic member 131 is provided with a groove along its own arrangement direction, and the second telescopic member 132 is snapped into the groove and matched. The second telescopic member 132 can slide along the groove relative to the first telescopic member 131. In this way, the position of the target plate 140 can be adjusted. The first telescopic member 131 and the second telescopic member 132 can move relative to each other along the arrangement direction, and the total length of the first telescopic member 131 and the second telescopic member 132 can be changed during the movement.

[0036] In some embodiments, the first telescopic member 131 and the second telescopic member 132 are each provided with a scale at least at the corresponding overlapping locations. The scale can be determined as needed. If more precise measurement is required, the minimum unit of the scale is mm, dmm, or a smaller unit. Because the target adjustment rod 130 can be flexibly adjusted according to on-site conditions, measurement only requires reading the scale reading and then entering it into the data input interface of the total station 200. Due to the setting of the scale, the auxiliary measurement tool 100 has sufficient accuracy and can match the high-precision measurement of the total station 200. In some embodiments, the plurality of target plates 140 include a first target 141 and a second target 142. The first target 141 is connected to the first telescopic member 131 and fixed with screws. The second target 142 is connected to the second telescopic member 132 and also fixed with screws. In this way, the relative positions of the first target 141 and the second target 142 can be changed by adjusting the relative positions of the first telescopic member 131 and the second telescopic member 132. The first target 141 and the second target 142 are plates marked with measurement points, respectively. The first target 141 and the second target 142 facilitate two-point measurement by the total station 200.

[0037] Please refer to Figure 3In some embodiments, the target adjustment rod 130 further includes a locking member 133, which is connected to the first telescopic member 131 and the second telescopic member 132 and is used to relatively lock the first telescopic member 131 and the second telescopic member 132. The locking member 133 is a screw, a bolt, or other parts that are convenient for fixing. The first telescopic member 131 is provided with a threaded hole, and the second telescopic member 132 is provided with a groove corresponding to the position. The locking member 133 passes through the first telescopic member 131 through the threaded hole and is then clamped into the groove of the second telescopic member 132. In this way, after the positions of the first telescopic member 131 and the second telescopic member 132 are relatively adjusted and determined, the first telescopic member 131 and the second telescopic member 132 can be fixed by tightening the locking member 133. The arrangement of the first telescopic member 131 and the second telescopic member 132 allows for more flexible adjustment of the position of the target plate 140 to meet the different conditions of on-site measurement.

[0038] In some embodiments, the first telescopic member 131 and the second telescopic member 132 are respectively matched cylindrical and the two are sleeved and connected. The size of the first telescopic member 131 is larger than that of the second telescopic member 132. The inner diameter of the first telescopic member 131 matches the outer diameter of the second telescopic member 132, so that the second telescopic member 132 can be placed in the first telescopic member 131. After placement, there is a gap between the first telescopic member 131 and the second telescopic member 132 to ensure that the first telescopic member 131 and the second telescopic member 132 can move relative to each other; the first telescopic member 131 and the second telescopic member 132 can be made of transparent materials, such as PP, acrylic, etc., and scales are provided on the first telescopic member 131 and the second telescopic member 132 to facilitate readings after the first telescopic member 131 and the second telescopic member 132 move relative to each other.

[0039] In some embodiments, the angle adjustment rod 120 includes a first adjustment rod 121 and a second adjustment rod 122. The first adjustment rod 121 is rotatable relative to the second adjustment rod 122, such as the first adjustment rod 121 and the second adjustment rod 122 are hinged, and the hinge adopts a conventional hinge structure, such as a hinge, and the hinge adopts an interference fit method, so that after the first adjustment rod 121 rotates relative to the second adjustment rod 122, it can also be relatively fixed. The first adjustment rod 121 is fixedly connected to the fixing member 110, such as the first adjustment rod 121 is welded and fixed to the fixing member 110, or other fixing methods that are convenient for connection can also be adopted. The second adjustment rod 122 is rotatably connected to the target adjustment rod 130, such as the end of the second adjustment rod 122 can rotate relative to itself, and the end is provided with a through hole. The first telescopic member 131 is connected to the second adjustment rod 122 through the through hole, so that the first telescopic member 131 can rotate relative to the second adjustment rod 122 to facilitate adjusting the position of the target plate 140. In actual measurement, if an obscured target is encountered, the fixing member 110 can be first fixed to the location to be measured, and then the angle adjustment rod 120 and / or the target adjustment rod 130 can be adjusted to rotate and extend, and at the same time, the two target plates 140 can be adjusted to a position where they can be measured by the total station 200, and then the readings on the scale are input into the measurement software interface of the total station 200 to complete the measurement.

[0040] In some embodiments, the angle adjustment rod 120 also includes a rotating joint 123, which is respectively connected to the end of the first adjustment rod 121 and the end of the second adjustment rod 122. If the rotating joint 123 adopts a hinge pin, corresponding through holes are respectively provided at the joints of the first adjustment rod 121 and the second adjustment rod 122, and the end of the second adjustment rod 122 can be snapped into the recess of the end of the first adjustment rod 121. After snapping in, the positions of the through holes correspond, and then the hinge pin is placed into the corresponding through hole for connection. This setting is a conventional hinge pin setting method, so that the relative angle of the first adjustment rod 121 and the second adjustment rod 122 can be adjusted through the rotating joint 123, and the pin at the hinge pin can adopt an interference fit with the shaft hole, so that the first adjustment rod 121 and the second adjustment rod 122 can also be relatively fixed after relative rotation. In some embodiments, the angle adjustment rod 120 also includes a pivot joint 124, which is fixed to the second adjustment rod 122. The fixed end of the pivot joint 124 is threadedly connected or welded to the second adjustment rod 122. The pivot port of the pivot joint 124 is cylindrical, and the first telescopic member 131 is placed in the cylinder and fixed, so that the pivot joint 124 is connected to the target adjustment rod 130. After the connection, the rotation angle of the target adjustment rod 130 can be adjusted through the pivot joint 124, thereby adjusting the position of the target plate 140.
