Description

Technical Field

[0001] This utility model relates to the field of traffic infrastructure testing technology, and in particular to an integrated multifunctional emergency rapid testing instrument. Background Technology

[0002] In the routine maintenance and post-disaster emergency assessment of transportation infrastructure, on-site technicians need to conduct a rapid and comprehensive preliminary survey of the verticality, spatial distance, and surface crack width of the structure. Currently, the commonly used detection methods rely on independent and decentralized specialized tools, such as handheld laser rangefinders for measuring distance, traditional plumb bobs for detecting verticality, and crack comparison calipers for measuring crack width.

[0003] However, in actual emergency testing scenarios, technicians need to carry multiple devices into complex environments to carry out operations. This dispersed carrying method not only increases the workload of the operators, but also seriously reduces the efficiency of on-site testing due to the frequent switching of tools between different testing items. In addition, the existing single-function testing tools have fixed structures. For example, the probe of a laser rangefinder cannot be adjusted in angle or position, making it difficult to obtain accurate data when facing narrow spaces or special locations with obstructions. At the same time, ordinary crack calipers have limited length and cannot effectively compare and measure deep cracks that are difficult for human hands to reach.

[0004] Therefore, this utility model proposes an integrated multifunctional emergency rapid detection instrument to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology, such as the single function and scattered nature of traffic infrastructure testing equipment leading to inconvenience in carrying on site and low testing efficiency, and the limited reliability of existing fixed testing structures due to their inability to adapt to complex and narrow spaces or obstructed environments, this utility model aims to provide an integrated multi-functional emergency rapid testing instrument with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an integrated multifunctional emergency rapid testing instrument, including a testing shell, a display screen fixedly connected to the upper surface of the front end of the testing shell, a testing mechanism disposed inside the testing shell, and a measuring mechanism fixedly connected to the bottom of the testing shell.

[0007] The testing mechanism includes a traction rope located on the left side inside the testing shell and a laser ranging module located on the right side inside the testing shell. The traction rope is connected to a plumb bob, which is magnetically attached to the side of the testing shell. The laser ranging module is connected to a fixed frame, and a rotating shaft is rotatably connected inside the fixed frame. The rotating shaft is connected to a laser probe. The measuring mechanism includes a fixed shell fixedly connected to the bottom of the testing shell. A crack comparison caliper is slidably connected to the bottom of the fixed shell and is slidably connected to the inside of a limit ruler.

[0008] Furthermore, the detection mechanism, measurement mechanism, and detection shell are combined in a partitioned integration manner. The traction rope and laser ranging module are respectively arranged on the left and right sides of the detection shell to avoid interference with each other. The measurement mechanism is suspended and fixed to the bottom of the detection shell through a fixed shell as an intermediary component to achieve vertical expansion of functions.

[0009] Preferably, the inner end of the traction rope is wound around the turntable, and a spring is installed on the inner side of the turntable. The turntable is connected to the inside of the detection shell by rotating the spring, and the traction rope can be automatically stored inside the detection shell by the elastic potential energy of the spring.

[0010] Preferably, a screw is provided on the right side of the rotating shaft, and a nut is fitted on the outer wall of the screw. The nut is fixedly connected to the left end of the laser probe, and the laser probe is rotatably connected to the right front end of the laser ranging module. By rotating the nut in conjunction with the screw, the axial position of the laser probe relative to the rotating shaft can be finely adjusted.

[0011] Preferably, the crack comparison caliper has standard lines and patterns engraved on its surface, and a slider is slidably connected to the left end of the crack comparison caliper. The slider is connected inside the telescopic frame, and the telescopic frame can be extended by the slider.

[0012] Preferably, the telescopic frame is slidably connected to the top of the fixed shell, and the telescopic frame structure is cross-telescopic to achieve folding and storage and unfolding extension. A positioning block is fixedly connected to the right end of the telescopic frame to limit the travel of the telescopic frame and prevent it from falling off.

[0013] Preferably, a bolt is provided through the side of the limit ruler, the bolt is threaded to the limit ruler, and the end of the bolt abuts against the surface of the crack comparison caliper. By tightening the bolt, the position of the crack comparison caliper can be fixed to facilitate reading.

[0014] Preferably, the detection housing has a handheld rectangular shape to accommodate one-handed operation, and the display screen is an OLED display screen, which is electrically connected to the laser ranging module to provide real-time feedback of ranging data.

[0015] Preferably, the laser probe is located at the front end of the laser ranging module, and the mounting bracket is fixedly connected between the laser ranging module and the laser probe. The laser probe can be rotated at multiple angles through the cooperation of the mounting bracket and the rotating shaft.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problems of existing traffic infrastructure detection equipment having a single function, making it difficult to simultaneously meet the needs of rapid preliminary investigation of verticality, distance and crack width, and being inconvenient to carry and with low efficiency in on-site deployment. It integrates an automatic rewinding vertical traction mechanism and a steerable and fine-tunable laser ranging mechanism inside the detection shell, and sets a retractable and expandable crack comparison measurement mechanism at the bottom. It achieves the effect of integrating multiple detection functions into one and being easy to operate with one hand, thereby significantly improving the efficiency and portability of on-site investigation.

[0018] 2. This utility model solves the problem that traditional fixed laser probes are easily blocked by the detection shell or unable to adjust to the optimal measurement angle when facing complex uneven surfaces or corner environments by setting a fixed frame at the front end of the laser ranging module and setting a rotating shaft connecting the laser probe and a fine adjustment structure with screws and nuts inside the fixed frame. It achieves the effect that the laser probe can flexibly turn the angle and fine adjust the extension position to adapt to diverse measurement environments and ensure the accuracy of the measurement benchmark.

[0019] 3. This utility model solves the problem that traditional physical contact crack measuring tools have a fixed length and cannot effectively compare cracks by setting a slider that runs through the telescopic frame and a telescopic frame structure that is cross-telescopic in combination with crack comparison calipers. This achieves the effect of flexibly expanding the measuring radius of crack comparison calipers, thereby enabling rapid screening and measurement of deep or distant cracks without the need for additional auxiliary equipment.

[0029] Example:

[0030] Please refer to Figures 1 to 6 This utility model provides an integrated multi-functional emergency rapid detection instrument, which aims to solve the problems of existing traffic infrastructure detection equipment having limited functions, making it difficult to simultaneously meet the rapid preliminary investigation needs of verticality, distance, and crack width, as well as being inconvenient to carry and having low efficiency in on-site deployment.

[0031] Please refer to Figure 1 and Figure 2 An integrated multifunctional emergency rapid detection instrument includes a detection shell 1 and a display screen 4 fixedly connected to the upper front surface of the detection shell 1. The detection shell 1 serves as the mounting base and handheld carrier for the entire integrated multifunctional emergency rapid detection instrument. The detection shell 1 is equipped with a detection mechanism 2 for vertical alignment and distance measurement. A measurement mechanism 3 for crack measurement is fixedly connected to the bottom of the detection shell 1. The display screen 4 is used to display detection data.

[0032] Please refer to Figure 4 , Figure 5 and Figure 6The detection mechanism 2 includes a traction rope 201 located on the left side inside the detection housing 1 and a laser ranging module 210 located on the right side inside the detection housing 1. A plumb bob 202 is fixedly connected to the end of the traction rope 201. The plumb bob 202 is magnetically attracted to the side of the detection housing 1. One end of the traction rope 201 is wound around a turntable 204. A spring 203 is installed inside the turntable 204. The turntable 204 is rotatably connected to the inside of the detection housing 1 through the spring 203. The traction rope 201 is stored inside the detection housing 1. A fixing frame 208 is fixedly connected to the front end of the laser ranging module 210. A rotating shaft 209 is rotatably connected inside the fixing frame 208. A laser probe 205 is fixedly connected to the rotating shaft 209. The laser probe 205 is located at the front end of the laser ranging module 210. The laser ranging module 210 and the laser probe 205 are connected through the fixing frame 208 and the rotating shaft 209.

[0033] Meanwhile, the measuring mechanism 3 includes a fixed shell 301 fixedly connected to the bottom of the detection shell 1. A crack comparison caliper 302 is slidably connected to the bottom inner side of the fixed shell 301. The crack comparison caliper 302 is slidably connected to the inside of the limiting ruler 303. The limiting ruler 303 is set inside the fixed shell 301. A slider 305 is slidably connected to the left end of the crack comparison caliper 302. The slider 305 is connected through the telescopic frame 306. The telescopic frame 306 is slidably connected to the top of the fixed shell 301.

[0034] In a preferred embodiment, in order to achieve fine adjustment of the position of the laser probe 205, a screw 207 is provided on the right side of the rotating shaft 209, and a nut 206 is sleeved on the outer wall of the screw 207. The nut 206 is fixedly connected to the left end of the laser probe 205, and the laser probe 205 is rotatably connected to the right front end of the laser ranging module 210. The extension state of the laser probe 205 can be adjusted by rotating the nut 206.

[0035] As another preferred embodiment, in order to realize the extension measurement and limiting of the measuring mechanism 3, the telescopic frame 306 has a cross telescopic structure. The right end of the telescopic frame 306 is fixedly connected to a positioning block 307. The positioning block 307 is used to prevent the telescopic frame 306 from detaching from the fixed shell 301. The side of the limiting ruler 303 is provided with a bolt 304. The bolt 304 is threadedly connected to the limiting ruler 303, and the end of the bolt 304 abuts against the surface of the crack comparison caliper 302 to fix the crack comparison caliper 302. The surface of the crack comparison caliper 302 is engraved with standard lines and patterns.

[0036] As another preferred embodiment, for ease of holding and display, the detection shell 1 is a handheld cuboid shape, and the display screen 4 is an OLED display screen 4, which is electrically connected to the laser ranging module 210.

[0037] Working principle: When verticality testing or positioning is required, the user holds the testing shell 1 and removes the plumb bob 202 from the side of the testing shell 1. Under the action of gravity, the plumb bob 202 hangs down naturally through the traction rope 201. Since the traction rope 201 is wound around the internal turntable 204 and the turntable 204 is connected to the spring 203, the user can adjust the length of the traction rope 201 and automatically rewind it by stretching or loosening the traction rope 201 and cooperating with the elasticity of the spring 203. Thus, the naturally hanging plumb bob 202 is used to establish a vertical reference or to assist in the calibration of the distance measuring point.

[0038] When distance measurement is required, the user aligns the laser probe 205 at the front of the detection housing 1 with the target to be measured. The laser ranging module 210 controls the laser probe 205 to emit and receive signals to calculate the distance and displays the result on the display screen 4. If a complex angle is encountered or the detection housing 1 itself obstructs the measurement line of sight, the user can rotate the shaft 209 to adjust the angle of the laser probe 205 and move the nut 206 on the screw 207 to fine-tune the extension position of the laser probe 205, thereby ensuring the smoothness of the measurement path and the accuracy of the reference point.

[0039] When crack measurement is required, the user uses the measuring mechanism 3 located at the bottom of the detection housing 1 to pull the crack comparison caliper 302 outward along the limit ruler 303. If the crack is far away or deep, the user can further pull the slider 305 to drive the telescopic frame 306 to unfold. The cross telescopic structure of the telescopic frame 306 extends the crack comparison caliper 302 to the crack to be measured. The user compares the reading with the standard lines and patterns on the surface of the crack comparison caliper 302 and the actual crack. After the measurement is completed, the user tightens the crack comparison caliper 302 by rotating the bolt 304 to fix the reading or position. Then, the telescopic frame 306 and the crack comparison caliper 302 are retracted. The positioning block 307 prevents the telescopic frame 306 from being overstretched and detached from the fixed housing 301 during this process.
