Description

Technical Field

[0001] This utility model relates to the field of engineering measurement auxiliary tools, specifically an adjustable-angle engineering measurement reflector bracket. Background Technology

[0002] Engineering surveying reflective supports are auxiliary tools used in conjunction with total stations and other surveying equipment for precise positioning. They are typically made of stainless steel or galvanized iron and come in various sizes. Their core function is to achieve stable positioning of the target point by fixing a reflector or prism. They are widely used in deformation monitoring of tunnels, bridges, building foundation pits, and other engineering projects. The total station emits infrared laser light to the reflector or prism on the support, calculates the distance using the principle of constant speed of light, and determines the coordinates of the target point by combining angle data.

[0003] Existing engineering surveying reflector brackets require angle adjustment to ensure that the infrared laser emitted by the total station can be incident perpendicularly on the reflector surface, thereby obtaining the highest reflection efficiency. Currently, the pitch angle of the reflector is adjusted by the knobs or clips on the bracket to make the reflector surface roughly aligned with the total station. However, this relies on operating experience, requires repeated testing and verification of the angle's rationality, and is time-consuming. Utility Model Content

[0014] 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.

[0015] Please see Figures 1-3 This utility model provides a technical solution: an adjustable angle engineering measurement reflective bracket, including a frame 1 and a reflective sheet 3; A mounting plate 2 is fixedly connected to one side of the top of the frame 1. The frame 1 and the mounting plate 2 cooperate to support the reflector 3. A support plate 6 is symmetrically welded to the top of the side of the mounting plate 2. The reflector 3 is rotatably connected to one side of the support plate 6 through a support shaft 7. The reflector 3 is used to achieve stable positioning of the measurement target point.

[0016] Specifically, the frame 1 and the mounting plate 2 work together to support the reflector 3.

[0017] exist Figures 1-5 In the middle: An adjustment mechanism 8 is provided between the reflector 3 and the mounting plate 2. The adjustment mechanism 8 is used to realize the rapid adjustment of the angle of the reflector 3. The adjustment mechanism 8 includes a support block 801 symmetrically welded to the bottom of the side of the mounting plate 2 and a guide rod 805 welded to the reflector 3. A lead screw 802 is rotatably connected to the inner side of a set of support blocks 801. The lead screw 802 is used to make the threaded frame 803 move vertically. The lead screw 802 is threadedly connected to the threaded frame 803 on the outer side. A guide frame 804 is symmetrically welded to the top of the threaded frame 803. The guide frame 804 and the guide rod 805 form a sliding structure. A handle 806 is welded to the bottom of the lead screw 802.

[0018] Specifically, rotating the handle 806 causes the lead screw 802 to rotate. Since the threaded bracket 803 is threadedly connected to the lead screw 802 and slidably connected to the mounting plate 2 via the limiting rod 807, the threaded bracket 803 drives the guide frame 804 to move vertically. Since the reflector 3 is rotatably connected to the support plate 6 via the support shaft 7 and slidably connected to the guide frame 804 via the guide rod 805, the reflector 3 deflects about the support shaft 7 as the axis, thereby achieving rapid adjustment of the angle of the reflector 3 to ensure that the infrared laser emitted by the total station can be perpendicularly incident on the surface of the reflector 3, thereby obtaining the highest reflection efficiency.

[0019] exist Figures 1-3 In the middle of the front end of the mounting plate 2, a display screen 4 is installed. The display screen 4 is used to indicate the deviation value. An tilt sensor 5 is installed in the middle of the front end of the reflector 3. The tilt sensor 5 is used to monitor the angle of the reflector 3 in real time.

[0020] Specifically, during the adjustment of the angle of the reflector 3, the tilt sensor 5 monitors the angle of the reflector 3 in real time and displays the deviation value on the display screen 4, so that the operator can make quick and accurate angle adjustments, significantly improving efficiency and accuracy.

[0021] exist Figure 4 In the middle: another set of support blocks 801 has a limiting rod 807 welded on the inner side, which forms a sliding structure with the threaded frame 803. The limiting rod 807 is used to make the threaded frame 803 move only in the vertical direction.

[0022] Specifically, the threaded bracket 803 is supported and limited by the limiting rod 807, so that the threaded bracket 803 can only move in the vertical direction.

[0023] exist Figure 5 In the middle: a support block 801 has a positioning groove 9 at an equal angle at the bottom end, and the handle 806 has a bolt 10 that is threaded inside and forms a locking structure with the positioning groove 9. The positioning groove 9 and the bolt 10 cooperate to prevent the handle 806 from rotating on its own.

[0024] Specifically, the positioning groove 9 and the bolt 10 are used to position the handle 806 in order to prevent the handle 806 from rotating on its own.

[0025] By rotating the bolt 10 to separate it from the positioning groove 9, the screw 802 is rotated by rotating the handle 806. Through the threaded action between the threaded bracket 803 and the screw 802, the threaded bracket 803 drives the guide frame 804 to move vertically. Through the rotation of the reflector 3 and the support plate 6 and the sliding action with the guide frame 804, the reflector 3 deflects about the support shaft 7 as the axis, thereby realizing the rapid adjustment of the angle of the reflector 3. During this process, the angle of the reflector 3 is monitored in real time by the tilt sensor 5 and the deviation value is displayed on the display screen 4 so that the operator can make quick and accurate angle adjustments, significantly improving efficiency and accuracy.

[0026] Electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source and controlled by a control box. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
