Description

Technical Field

[0001] This utility model belongs to the technical field of laser displacement sensor monitoring equipment installation, and particularly relates to an auxiliary device for laser displacement monitoring. Background Technology

[0002] In activities requiring the simultaneous installation of laser displacement sensor monitoring equipment in three dimensions, the target plate and sensor bracket are critical components, and their installation stability and ease of use are paramount. When monitoring the X, Y, and Z directions simultaneously, the traditional method of installing one sensor bracket in each of the three directions to secure the sensor equipment is difficult to implement in space-constrained environments where suitable locations for the brackets and target plates are hard to find. For example, in a power plant boiler, where expansion displacement is monitored at a measuring point, the small area surrounded by fences makes it impossible to simultaneously install target plates and brackets in all three directions without interference. Furthermore, traditional installation methods involve complex procedures for adjusting the target plate and corresponding sensors, requiring multiple tools and time-consuming adjustments to the fixing devices. These factors result in the monitoring environment setup typically taking ten minutes or more, significantly reducing installation efficiency. Utility Model Content

[0003] To address the problem described in the background art that the traditional installation method involves complex operations and significantly reduces installation efficiency when adjusting the target plate and corresponding sensors, the present invention proposes the following technical solution:

[0004] An auxiliary device for laser displacement monitoring includes: a guide bracket, multiple steering modules, multiple laser probes, and a reflector base; one end of the guide bracket is fixedly connected to the object to be measured, and the other end of the guide bracket is fixedly provided with multiple mounting columns; each mounting column is parallel to each other, and the movable end of each mounting column is fixedly connected to a steering module; the rotation directions of each steering module are perpendicular to each other, and each steering module includes: a base and a rotating part; one end of the base is fixedly provided on the mounting column, and the other end of the base is hinged to one end of the rotating part, and a laser probe is fixedly provided on the other side of the rotating part; the reflector base is provided on the outer periphery of the laser probe, and each laser probe is perpendicular to one of the surfaces of the reflector base.

[0006] Furthermore, the surface of the base is recessed to form a positioning groove that matches the rotating part. The groove walls opposite to the positioning groove are respectively provided with paired arc-shaped grooves and second mounting holes.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be described in further detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

[0015] It should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0016] Figure 1 This is a schematic diagram of an auxiliary device for laser displacement monitoring according to an embodiment of the present invention.

[0017] Reference Figure 1 An auxiliary device for laser displacement monitoring according to an embodiment of the present invention includes: a guide bracket 1, a reflector 4, multiple steering modules 2, multiple laser probes 3, and the reflector 4. One end of the guide bracket 1 is fixedly connected to the object to be measured, and the other end of the guide bracket 1 is connected to the corresponding steering module 2 through multiple mounting posts 11. The rotation directions of each steering module 2 are perpendicular to each other, and each steering module 2 includes a base 21 and a rotating part 22 hinged together. The base 21 is fixed to the end of the mounting post 11 through a connector 6, and the surface of the rotating part 22 is fixed to the laser probe 3 through the connector 6. The reflector 4 is disposed on the outer periphery of the laser probe 3, and the extension direction of each laser probe 3 is perpendicular to one of the surfaces of the reflector 4.

[0018] Figure 2 This is a schematic diagram of the steering module according to an embodiment of the present utility model.

[0019] Reference Figure 2 Specifically, the surface of the base 21 is recessed to form a positioning groove 211, and the surface of the rotating part 22 is recessed to form a limiting groove 221. First mounting holes 222 are respectively provided on the groove walls on both sides of the limiting groove 221, and arc-shaped grooves 212 and second mounting holes 213 are respectively provided on the groove walls on both sides of the positioning groove 211. The second mounting hole 213 matches the first mounting hole 222, and the arc-shaped groove 212 matches the first mounting hole 222; the arc-shaped groove 212 and the second mounting hole 213 are concentrically arranged. The connecting piece 6 inserted into the first mounting hole 222 and the second mounting hole 213 serves as a hinge shaft between the base 21 and the rotating part 22. Before the base 21 and the rotating part 22 are locked, the rotating part 22 can rotate relative to the base 21 with the connecting piece 6 as its axis, thereby adjusting the position of the laser probe 3. During the rotation of the rotating part 22, the first mounting hole 222, which matches the arc-shaped groove 212, moves within the arc-shaped groove 212 along the arc direction of the arc-shaped groove 212. When the connector 6 is inserted into the arc groove 212 and the first mounting hole 222 that matches the arc groove 212, the rotating part 22 and the base 21 are locked together.

[0020] Furthermore, a positioning hole 223 is provided at the bottom of the limiting groove 221, and the laser probe 3 is detachably fixed to the surface of the rotating part 22 by fasteners such as screws. The width of the limiting groove 221 is smaller than the width of the positioning groove 211. When the base 21 and the rotating part 22 are hinged together, the two side walls of the limiting groove 221 abut against the two side walls of the positioning groove 211 respectively.

[0021] Specifically, the base 21 includes a first plate 41, a second plate 42, and a third plate 43. The first plate 41, second plate 42, and third plate 43 are perpendicular to each other and share a common intersection point. The surfaces of the first plate 41, second plate 42, and third plate 43 are perpendicularly connected to the extension direction of one of the laser probes 3. During laser testing, the reflector 4 is positioned outside the object under test and remains relatively stationary with respect to the ground to avoid interference with the test results. In this embodiment, there are three steering modules 2. The rotation directions of each steering module 2 are perpendicular to each other, forming an orthogonal arrangement. Each steering module 2 is located on a guide bracket 1 at a different height from the object under test.

[0022] During the laser test, the reflector 4 remains relatively stationary relative to the ground and is positioned on the outer periphery of each laser probe 3. The guide bracket 1 and the object under test (in this embodiment, a boiler; in other embodiments, it can be any movable object) are connected. The laser probe 3 emits laser light onto one side of the reflector 4, and records the downward displacement of the reflected laser light on the surface of the reflector 4, thereby completing the data acquisition work for subsequent laser testing.

[0023] In summary, this utility model uses a guide bracket to keep the object under test fixed. Each rotating module is vertically arranged in pairs on the guide bracket. After adjusting the position of the laser probe on each rotating module, the test environment can be quickly set up and debugged by placing a reflector on the outer periphery of the laser probe.
