Description

Technical Field

[0001] The utility model relates to the technical field of engineering detection, in particular to a detector mobile device used for detecting shallow surface waves on urban roads. Background Art

[0002] Surface waves are elastic waves that propagate along the surface of a medium. Generally, longer wavelengths allow for greater depth measurements. Surface waves can be generated in foundations in a variety of ways and are primarily used to detect foundation stratification, the properties of each layer, and soil defects.

[0003] Traditional active-source surface-wave instruments mostly use conical velocity detectors. When collecting seismic surface-wave data, a number of geophones are arranged in a straight line above the measuring point at regular intervals and inserted into the ground. After vibration data collection is complete, the geophones must be manually moved one by one to the next measuring point. When surveying urban roads, the pavement is often concrete or asphalt, making it difficult to secure the geophones. Furthermore, the length of the survey line often ranges from several hundred meters to several kilometers. Whether geophones are sequentially placed at each measuring point or manually moved along the line, both methods present low efficiency issues and require urgent solutions. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a detector moving device for shallow surface wave detection on urban roads, which does not require manual movement of the detectors one by one and can achieve efficient surface wave detection operations.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A detector mobile device for detecting shallow surface waves on urban roads includes a traveling trolley provided with a lifting frame capable of lifting and lowering movement. The lifting frame is equipped with at least two detector assemblies arranged in sequence along the direction of travel of the traveling trolley. When the lifting frame descends, the detection ends of all the detector assemblies are in contact with the ground.

[0007] As a further solution of the present invention: the detector assembly includes a detection detector, the detection detector is a floating installation structure perpendicular to the ground, and the bottom end of the detection detector constitutes the detection end.

[0008] As a further solution of the present invention: the detector assembly includes a support base installed on the lifting frame, a plumb hole is arranged on the support base, and the detection detector is floatingly plugged into the plumb hole.

[0009] As a further solution of the present invention: a slide rail arranged along the traveling direction of the trolley is fixed on the lifting frame, and the support seat is slidably fitted on the slide rail.

[0010] As a further solution of the present invention, it also includes a scale for measuring the distance between adjacent support seats.

[0011] As a further solution of the present invention: a vertically arranged guide shaft is fixed on the traveling trolley, a lifting frame sliding sleeve is arranged on the guide shaft, and a linear motor for driving the lifting frame to perform lifting motion is provided on the traveling trolley.

[0012] As a further solution of the present invention: the traveling trolley includes traveling wheels for moving the traveling trolley, and an encoder for measuring the travel distance of the traveling trolley is installed on the body of the traveling trolley located at the traveling wheels.

[0013] As a further solution of the present invention: both ends of the walking trolley are equipped with hanging buckles.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The present invention integrates multiple geophone assemblies onto a trolley. The trolley moves along the survey line, driving all geophone assemblies to move synchronously along the survey line. Furthermore, all geophone assemblies are raised and lowered by a lifting frame. This allows the trolley to move while the trolley is in motion, driving all geophone assemblies to separate from the ground, preventing wear on the detection ends of the geophone assemblies and reducing their service life. When the trolley reaches a predetermined position, the lifting frame lowers all geophone assemblies until their detection ends contact the ground, enabling continuous, synchronized surface wave detection using multiple geophone assemblies. This eliminates the need to manually move the geophone assemblies one by one, effectively improving the efficiency and convenience of surface wave detection.

[0016] 2. In the detector assembly, the bottom of the detection detector forms the detection end, and the detection detector and the plumb socket of the support base adopt a through-plug-in fit, allowing the detection detector to slide up and down. When the traveling trolley is detecting on uneven ground, even if the lifting frame drives the detection ends of some detection detectors to contact the ground, the detection detectors in contact with the ground can move upward relative to the lifting frame, while the detection detectors not in contact with the ground continue to move downward with the lifting frame. This ensures that all detection detectors can contact the ground, improving the adaptability of the detector moving device to road conditions.

[0017] 3. The support base and lifting frame for installing the detection detector adopt a sliding fit, so that the distance between adjacent detection detectors can be adjusted along the traveling direction of the trolley; and the distance between the detection detectors can be controlled by a scale to meet different detection requirements.

[0018] 4. The encoder setting can quickly obtain the detection distance without manually measuring the distance with a ruler.

[0019] 5. The hook setting can be used to install push-pull handles or connect multiple traveling trolleys in series to arbitrarily increase or decrease the number of detectors to meet different detection needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] For ease of understanding, the specific structure and working mode of the present invention are further described below with reference to the accompanying drawings:

[0025] The specific structure of the utility model refers to Figure 1-2As shown, its main structure includes a trolley 10 and a detector assembly 40 mounted on the trolley 10. The trolley 10 is equipped with a lifting frame 20 that can be raised and lowered. The lifting frame 20 is mounted with at least two detector assemblies 40 arranged sequentially along the direction of travel of the trolley 10. When the lifting frame 20 is lowered, the detection ends of all detector assemblies 40 are in contact with the ground. By integrating multiple detector assemblies 40 on the trolley 10, the movement of the trolley 10 along the survey line can drive all detector assemblies 40 to move synchronously along the survey line. In addition, all the detector assemblies 40 are lifted and lowered by the lifting frame 20. When the traveling trolley 10 moves, all the detector assemblies 40 can be driven to separate from the ground, thereby preventing the detection ends of the detector assemblies 40 from being worn and reducing the service life of the detector assemblies; and when the traveling trolley 10 moves to a predetermined position, the lifting frame 20 drives all the detector assemblies 40 to descend until their detection ends are in contact with the ground, thereby realizing continuous and synchronous surface wave detection operations of multiple detector assemblies 40, without the need to manually move the detector assemblies 40 one by one, effectively improving the work efficiency and convenience of the surface wave detection operation.

[0026] In specific implementation, the detector components 40 are generally set to six groups, which can also be increased or decreased according to actual needs to ensure that enough data can be collected for processing at one time.

[0027] Specifically, such as Figure 2 As shown, the detector assembly 40 includes a detection detector 42, which is a floating installation structure perpendicular to the ground. The bottom end of the detection detector 42 constitutes the detection end. This floating installation structure ensures that all detection detectors 42 can conform to the ground even when the ground is uneven, improving the adaptability of the detector mobile device to road conditions.

[0028] In actual implementation, Figure 2 As shown, the detector assembly 40 includes a support base 41 mounted on the lifting frame 20. The support base 41 is provided with a plumb hole 411, and the detection detector 42 is floatingly plugged into the plumb hole 411. The detection detector 42 and the plumb hole 411 of the support base 41 are plugged into each other through the support base 41, so that the detection detector 42 is in a movable state that can slide up and down. When the traveling trolley 10 is detecting on uneven ground, even after the lifting frame 20 drives the detection ends of some detection detectors 42 to contact the ground, the detection detectors 42 that have contacted the ground can move upward relative to the lifting frame 20, while the detection detectors 42 that are not in contact with the ground continue to move downward with the lifting frame 20, to ensure that all detection detectors 42 can contact the ground.

[0029] Of course, the floating installation of the above-mentioned detection detector 42 can also be connected to the bottom of the support base 41 through a telescopic rod, but it is obvious that the telescopic rod connection has the problems of insufficient convenience in assembly and disassembly and small sliding.

[0030] On the basis of the above, if Figure 1 As shown, a slide rail 21 arranged along the travel direction of the trolley 10 is fixed on the lifting frame 20, and the support seat 41 is slidably fitted on the slide rail 21, so that the distance between adjacent detection detectors 42 can be adjusted along the travel direction of the trolley 10. The detector moving device also includes a scale 12 for measuring the distance between adjacent support seats 41. The distance between the detection detectors 42 is controlled by the scale 12, thereby ensuring the accuracy of the adjustment of the distance between adjacent detection detectors 42 to meet different detection needs. In actual implementation, the support seat 41 and the slide rail 21 rely on the friction between each other to achieve the position positioning of the support seat 41. Of course, a set screw that is locked with the slide rail 21 can also be provided on the support seat 41 to ensure that the support seat 41 is in a stable state after adjustment.

[0031] On the basis of the above, if Figure 1 As shown, a vertically arranged guide shaft 13 is fixed on the traveling trolley 10, and the lifting frame 20 is slidably sleeved on the guide shaft 13. The traveling trolley 10 is provided with a linear motor 30 for driving the lifting frame 20 to perform lifting motion. The linear motor 30 is used in conjunction with the guide shaft 13 to realize the lifting motion of the lifting frame 20, which has good driving stability.

[0032] The walking trolley 10 includes a walking wheel 11 for moving the walking trolley 10. An encoder 50 for measuring the moving distance of the walking trolley 10 is installed on the body of the walking wheel 11 of the walking trolley 10, which can be used to accurately record the detection distance of the walking trolley 10, avoiding the traditional detection of manually measuring the distance with a ruler.

[0033] Both ends of the walking trolley 10 are equipped with hooks 60. The setting of the hooks 60 can be used to install push-pull handles or realize the series connection of multiple walking trolleys 10. According to the number of detection detectors 42 required, several walking trolleys 10 are connected in series to meet different detection needs, thereby improving the applicability of the device.

[0034] Of course, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also encompasses the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations that fall within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
