[0002] In surveying and setting out work, an optical alignment prism is required for turning point measurement, traverse measurement, trigonometric leveling measurement, and total station setting out and orientation measurement. The traditional optical alignment prism is troublesome to adjust for centering and leveling, and takes a long time. In turning point measurement, it often takes three to five minutes to level and erect the instrument and equipment. Especially in a dimly lit or tunnel environment, with poor lighting, muddy ground or other conditions when erecting the instrument, using the traditional optical alignment prism is more time-consuming and the operation is more complicated. When using the traditional optical alignment prism in trigonometric leveling measurement, it is difficult to measure the height of the prism center and the ground height, and there is generally an inclined distance error of about 3 mm in general measurement. Content of the Utility Model

[0003] To solve the above problems, the utility model aims to provide a measuring equipment for a laser alignment prism, which has a simple structure, is convenient to use, and can measure the horizontal distance and height between the prism center and the ground point, improving the accuracy of total station trigonometric leveling measurement.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0005] A measuring equipment for a laser alignment prism includes a base body. Two long tube spirit levels arranged in a 90-degree stagger are installed on the top of the base body, and a prism rod is installed at the center of the top. A laser module is installed inside the base body, and a plurality of base locking rods are arranged at the bottom of the base body.

[0006] Further, it also includes a scale box. A scale box insertion rod is arranged on the top of the scale box, and a scale box connection hole corresponding to and matching the scale box insertion rod is arranged on the side of the base body. A height measuring tape is installed inside the scale box, and a height measuring hole is opened at a position near the height measuring tape at the lower part of the scale box.

[0007] Further, the base body includes a base cover plate and a base housing. A cover plate lip is arranged on one side of the base cover plate, and a groove corresponding to and matching the cover plate lip is arranged on the base housing.

[0008] Further, a lapping platform and a locking hole are arranged on the other side of the base housing. The base cover plate is provided with a lapping ring and a locking position corresponding to and matching the lapping platform. The locking hole and the locking position are used for installing a locking nut for fixed connection.

[0009] Further, the laser module includes a power supply, a laser head, a power supply wire, and a power switch connected in series. The power supply is installed on the side wall of the base housing, the laser head is installed at the center of the inner bottom of the base housing corresponding to and matching the prism rod, and the power switch is installed on the top of the base cover.

[0010] Beneficial effects: In the measurement, the base body of the present invention is placed on top of a conventional measurement prism base and locked and connected through a base locking rod, and a measurement prism head is inserted on the prism rod; after the overall assembly of the prism is completed, it is centered and placed on the measurement tripod. By adjusting the height of the legs of the measurement tripod up and down, the long tube level bubble is centered. The long tube level bubble can make the overall prism in a roughly horizontal state. Subsequently, by rotating the base angle screw on the conventional measurement prism base, the two horizontal bubbles of the prism are centered. The overall prism base is already in a highly leveled state. After turning on the laser module, the laser centering spot can be aligned with the center of the control point. After the prism base is centered on the ground point, the measurement reading is taken with a tape measure, and the height of the prism center or the height of the prism centered on the ground point can be obtained through calculation.

[0015] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0016] The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0017] Embodiment 1

[0018] See Figures 1-3: A laser alignment prism measuring device, comprising a base body 1, on the top of the base body 1 are installed two long tube spirit levels 2 arranged staggeredly at 90 degrees, at the top center is installed a prism rod 3, inside the base body 1 is installed a laser module, and at the bottom of the base body 1 are provided a number of base locking rods 4.

[0019] It should be noted that during the measurement, the base body is placed on top of a conventional measurement prism base and locked and connected through the base locking rods, and a measurement prism head is inserted on the prism rod; after the whole prism is assembled, it is centered and placed on top of a measurement tripod, and the long tube spirit level is centered by adjusting the height of the legs of the measurement tripod up and down. The long tube spirit level can make the whole prism be roughly horizontal. Subsequently, by rotating the base angle screw on the conventional measurement prism base, the two horizontal spirit levels of the prism are centered. The whole prism base is already highly leveled. After turning on the laser module, the laser alignment spot can be aligned with the center of the control point. After the prism base is centered with the ground point, the measurement reading is taken through a tape measure, and the prism center height or the height of the prism centered with the ground point can be obtained through calculation. Thus, the work of using the laser alignment prism for turning point measurement is completed.

[0020] In a specific example, it further includes a tape box 5. On the top of the tape box 5 is provided a tape box insertion rod 501. On the side of the base body 1 is provided a tape box connection hole 101 corresponding to and matching the tape box insertion rod 501. Inside the tape box 5 is installed a height measuring tape 502. Near the position of the height measuring tape 502 at the lower part of the tape box 5 is provided a height measuring hole 503.

[0021] It should be noted that the distance between the height measuring hole and the prism center height or between the prisms is a fixed value tested in advance. In addition, the positions of the tape box and the laser are staggered from each other and will not affect the laser positioning; by pulling the height measuring tape through the tape box insertion rod and the tape box connection hole on the tape box and reading the tape measure reading, the prism center height or the height of the prism centered with the ground point can be obtained through calculation.

[0022] In a specific example, the base body 1 includes a base cover plate 102 and a base housing 103. On one side of the base cover plate 102 is provided a cover plate convex lip 1021, and on the base housing 103 is provided a groove corresponding to and matching the cover plate convex lip 1021.

[0023] It should be noted that the base cover plate and the base housing of the base body in this embodiment are made of plastic elastic materials, and the two are spliced into a whole through the cooperation of the cover plate convex lip and the groove.

[0024] In a specific example, a lapping platform and a locking hole are provided on the other side of the base housing 103. The base cover plate 102 is provided with a lapping ring 1022 corresponding to and matching the lapping platform and a locking position. The locking hole and the locking position are used for installing a locking nut 6 for fixed connection.

[0025] In this embodiment, the lapping platform and the lapping ring are matched with the locking hole, and the locking nut is installed in the locking position for fixed installation, so as to improve the installation stability between the base cover plate and the base housing.

[0026] In a specific example, the laser module includes a power supply 7, a laser head 8, a power supply cord 9, and a power supply switch 10 that are connected in series. The power supply 7 is installed on the side wall of the base housing 103, the laser head 8 is installed at the center position of the inner bottom of the base housing 103 and corresponds to and matches the prism rod 3, and the power supply switch 10 is installed on the top of the base cover plate 102.

[0027] When the power supply switch is turned on, the laser head emits a ray, and the ray forms a circular light spot with a diameter of 1 mm on the ground. The measurement control point can be centered through the light spot.

[0028] In summary, the laser module and the measuring ruler box provided in this embodiment do not need to be frequently calibrated and maintained. The laser alignment does not require manual aiming through an eyepiece like traditional optical alignment, saving measurement time and increasing measurement accuracy; using a special height measuring ruler can obtain the accurate height difference between the prism center and the ground control point during prism height measurement, and the measurement accuracy and speed are better than those of traditional optical alignment prisms.

[0029] The overall internal structure of the centering base in this embodiment is simple, easy to use, not easy to be damaged, and convenient to repair. The laser emitted by the prism can pass through the ground laser point to quickly measure and transfer points and align with the ground points. In the case of dim light brightness, there is no need to illuminate to align with the ground points; and this device can be connected to the measuring ruler box. By pulling the tape measure of the ruler box, the horizontal distance height of the prism center can be measured; the construction process is reduced, the work efficiency is greatly improved, the frequency of rechecks is reduced, and the measurement work accuracy is improved.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
