Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, specifically a surveying instrument positioning device for surveying engineering. Background Technology

[0002] Surveying instruments are instruments and devices designed and manufactured for data acquisition, processing, and output in surveying operations. They are various instruments used for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry during the planning, design, construction, and operation management phases of engineering construction. To ensure the overall accuracy and convenience of surveying, the surveying instrument needs to be placed on a surveying instrument positioning device.

[0003] A search revealed Chinese patent CN219243126U, which discloses a positioning device for a surveying instrument used in surveying engineering. The device includes a sleeve and an adjusting assembly. The bottom of the adjusting assembly is fixedly connected to the top of the sleeve. The adjusting assembly includes a rotating seat, the bottom of which is fixedly connected to the top of the sleeve. A threaded sleeve is rotatably connected to the inner side of the rotating seat, and a screw is threadedly connected to the inner wall of the threaded sleeve. This utility model provides a positioning device for a surveying instrument used in surveying engineering. The rotation of the rotating ring drives the threaded sleeve to rotate, which in turn drives the screw to move upwards. The movement of the screw drives the connecting plate to move upwards, which in turn moves the mounting base and the surveying instrument upwards, thereby adjusting the height of the surveying instrument. The operation is simple and convenient, eliminating the need for separate time to fix the position of the screw, thus making it easier for surveyors to use.

[0004] Although the above-mentioned utility model can locate the position of the surveying instrument, the surveying instrument is not convenient for users to carry. During the carrying process, users need to pick it up, which increases the labor intensity of users and thus reduces the practical effect. Utility Model Content

A movable sleeve is threaded onto the outer surface of the lead screw. Movable plates are fixed to both the left and right sides of the movable sleeve. Downward moving rods are fixed to both the left and right ends of the lower surface of the movable plate. The lower surfaces of the four downward moving rods penetrate and extend to the lower surface of the base plate and are fixed to the same movable plate. Multiple insert rods are fixed to the lower surface of the movable plate.

[0008] Furthermore, the number of casters is eight, and the eight casters are evenly distributed on the front and rear sides of the left and right ends of the lower surface of the base plate.

[0009] Furthermore, the left and right ends of the opposite sides of the inner wall of the base plate are provided with sliding grooves, and the two movable plates are fixed with sliders on opposite sides. The sliders move linearly up and down in the inner cavity of the sliding grooves.

[0010] Furthermore, a fixing groove is provided on the lower surface of the base plate, and the size of the inner cavity of the fixing groove is adapted to the size of the moving plate.

[0011] Furthermore, the bottom of the insertion rod is tapered, and multiple insertion rods are evenly distributed on the lower surface of the moving plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 The surveying instrument positioning device for surveying engineering in this embodiment includes a base plate 1, an electric telescopic rod 2 fixed at the center of the upper surface of the base plate 1, a support plate 3 fixed on the upper surface of the electric telescopic rod 2, a surveying instrument body 4 provided on the upper side of the support plate 3, and a portable mechanism 5 for easy carrying by the user provided at both ends of the lower surface of the base plate 1. A positioning mechanism 6 for positioning the surveying instrument body 4 is provided at the center between the opposite sides of the front and rear side walls of the inner cavity of the support plate 3.

[0024] In this embodiment, by activating the electric telescopic rod 2, the extension of the electric telescopic rod 2 causes the support plate 3 fixed on its surface to rise, thereby causing the surveying instrument body 4 to rise until a suitable measurement height is reached.

[0025] Please see Figures 2 to 3 To facilitate carrying the surveying instrument body 4, the portable mechanism 5 in this embodiment includes two universal wheels 501 fixed to the left and right ends of the lower surface of the base plate 1. A lead screw 502 is rotatably connected to the middle of the inner top wall and the inner bottom wall of the base plate 1 via a bearing. A driven bevel gear 503 is fixed to the bottom of the outer surface of the lead screw 502. A driving bevel gear 504 is meshed with the right side of the driven bevel gear 503. A drive motor 505 is fixed to the right end of the inner bottom wall of the base plate 1. The output shaft of the drive motor 505 is fixed to the inner cavity of the driving bevel gear 504. When moving the surveying instrument body 4, the electric telescopic rod 2 on the lower side of the surveying instrument body 4 can be held by hand to move the base plate 1 through multiple universal wheels 501. When moving to the target point for measurement, the drive motor 505 can be started, and the output shaft of the drive motor 505 rotates to drive the driving bevel gear 504 to rotate.

[0026] The outer surface of the lead screw 502 is threaded with a movable sleeve 506. The rotation of the driving bevel gear 504 causes the driven bevel gear 503, which is meshed with it on its left side, to rotate. The rotation of the driven bevel gear 503 drives the lead screw 502, which is fixed in its inner cavity, to rotate. The rotation of the lead screw 502 causes the movable sleeve 506, which is threaded on its surface, to move downward. Movable plates 507 are fixed on both the left and right sides of the movable sleeve 506. Downward moving rods 508 are fixed at both ends of the lower surface of the movable plate 507. The lower surfaces of the four downward moving rods 508 penetrate and extend to the lower surface of the base plate 1 and are fixed with the same moving plate 509. Multiple insert rods 510 are fixed on the lower surface of the moving plate 509. The downward movement of the movable sleeve 506 causes the movable plates 507, which are fixed on its left and right sides, to move downward linearly, thereby pushing the downward moving rods 508 to move downward. This causes the moving plate 509 to drive the multiple insert rods 510 to move downward until the insert rods 510 enter the ground, thus positioning the base plate 1.

[0027] In this embodiment, there are eight casters 501. The eight casters 501 are evenly distributed on the front and rear sides of the left and right ends of the lower surface of the base plate 1. Slide grooves are provided on the left and right ends of the opposite side of the inner wall of the base plate 1. Slide blocks are fixed on the opposite side of the two movable plates 507. The slide blocks move up and down linearly in the inner cavity of the slide groove to limit the movement of the movable sleeve 506 so that it can only move in a straight line.

[0028] The bottom surface of the base plate 1 is provided with a fixing groove, the size of the inner cavity of the fixing groove is adapted to the size of the moving plate 509, the bottom of the insertion rod 510 is tapered, and multiple insertion rods 510 are evenly distributed on the bottom surface of the moving plate 509.

[0029] It should be noted that during measurement, multiple insertion rods 510 can be inserted into the ground to keep the position of the base plate 1 fixed, thereby ensuring the accuracy of the measurement results of the surveying instrument body 4.

[0030] Please see Figure 4To position the surveying instrument body 4, the positioning mechanism 6 in this embodiment includes a shaft 601 rotatably connected to the center between opposite sides of the front and rear side walls of the inner cavity of the support plate 3 via bearings. A rotating gear 602 is fixed to the outer surface of the shaft 601, and toothed plates 603 are meshed on both the upper and lower sides of the rotating gear 602. Rotating the shaft 601 causes the rotating gear 602 fixed to the surface to rotate, and the rotation of the rotating gear 602 causes the two toothed plates 603 meshing with it to move relative to each other. On the opposite side of 03, a first connecting rod 604 and a second connecting rod 605 are fixed at the left and right ends respectively. The upper surfaces of the first connecting rod 604 and the second connecting rod 605 penetrate the support plate 3 and extend to the upper side of the support plate 3, where a clamping plate 606 is fixed. The rotation of the rotating gear 602 causes the two gear plates 603 that are meshed with it to move relative to each other, which in turn causes the first connecting rod 604 and the second connecting rod 605 to move relative to each other, and causes the two clamping plates 606 to move relative to each other, which can clamp the surveying instrument body 4 and thus position it.

[0031] In this embodiment, the clamping plate 606 has an inverted U-shaped cross-section. The front of the shaft 601 extends through and to the front side of the support plate 3. Limiting blocks are fixed on both the front and rear sides of the toothed plate 603. Limiting grooves that are adapted to the size of the limiting blocks are opened at the upper and lower ends of the opposite side of the front and rear side walls of the inner cavity of the support plate 3.

[0032] It should be noted that by driving the first connecting rod 604 and the second connecting rod 605 and the two clamping plates 606 to move relative to each other, the surveying instrument body 4 can be clamped and thus positioned. The process is relatively convenient and improves the positioning efficiency.

[0033] The working principle of the above embodiments is as follows:

[0034] (1) When moving the surveying instrument body 4, the electric telescopic rod 2 on the lower side of the surveying instrument body 4 can be held by hand to move the base plate 1 through multiple universal wheels 501. When moving to the target point for measurement, the drive motor 505 can be started. The output shaft of the drive motor 505 rotates and drives the active bevel gear 504 to rotate. The rotation of the active bevel gear 504 causes the driven bevel gear 503 meshed on its left side to rotate. The rotation of the driven bevel gear 503 drives the lead screw 502 fixed in its inner cavity to rotate. The rotation of the lead screw 502 causes the movable sleeve 506 threaded on its surface to move downward. The downward movement of the movable sleeve 506 causes the movable plates 507 fixed on its left and right sides to move downward linearly, thereby pushing the downward moving rod 508 to move downward. Thus, the moving plate 509 drives multiple insert rods 510 to move downward until the insert rods 510 enter the ground, which can position the base plate 1.

[0035] (2) By activating the electric telescopic rod 2, the extension of the electric telescopic rod 2 causes the support plate 3 fixed on its surface to rise, thereby causing the surveying instrument body 4 to rise until a suitable measurement height is reached; when positioning the surveying instrument body 4, the surveying instrument body 4 is placed on the upper side of the support plate 3, and then the shaft 601 is rotated. The rotation of the shaft 601 causes the rotating gear 602 fixed on the surface to rotate. The rotation of the rotating gear 602 causes the two toothed plates 603 meshing with it to move relative to each other, thereby causing the first connecting rod 604 and the second connecting rod 605 to move relative to each other, and causing the two clamping plates 606 to move relative to each other, so that the surveying instrument body 4 can be clamped and thus positioned.
