Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering survey technology, and in particular to a mobile measuring device for geotechnical engineering survey. Background Technology
[0002] Engineering surveying is the on-site investigation and mapping work conducted to ascertain the geological and geographical environmental characteristics and other natural conditions related to engineering construction within a construction area. It includes tasks such as horizontal control surveying, vertical control surveying, topographic surveying, photogrammetry, route surveying, and drawing and mapping. Its task is to provide scientific basis for the site selection, design, and construction of the project.
[0003] The tripod-type measuring devices widely used in current geotechnical engineering investigation sites have systemic defects: the three support legs of traditional equipment lack an overall locking mechanism during movement, forcing operators to use both hands to hug all the support legs or repeatedly disassemble and assemble parts, which not only results in low handling efficiency but also makes it easy for the support legs to fall off due to unstable grip; at the same time, such equipment completely lacks a dedicated carrying structure, and forcibly dragging it can easily cause deformation of the support leg connectors, deviation of the rotary table, and inaccuracy of precision measuring instruments. Utility Model Content
[0004] The purpose of this invention is to provide a mobile geotechnical engineering surveying device that solves the problem that traditional surveying equipment requires both hands to hold the support legs when moving, or that the support legs may fall off due to poor grip.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mobile geotechnical engineering survey measuring device, comprising three support legs, a rotating platform mounted on the three support legs, and a measuring instrument mounted on the rotating platform. Two of the support legs are provided with rotating grips, which rotate and merge to the same side, surrounding a single support leg, and the side of the rotating grips abuts against the single support leg.
[0006] Furthermore, the rotating grip plate includes a first-stage fixed plate, a second-stage rotating plate, and a rotating shaft. The first-stage fixed plate is fixedly connected to the support foot, and the first-stage fixed plate is provided with a receiving groove. The rotating shaft is slidably disposed in the receiving groove, and the second-stage rotating plate is rotatably connected to the rotating shaft.
[0007] Furthermore, the front end of the second-order rotating plate is provided with a gripping handle.
[0008] Furthermore, the first-stage fixed plate has a fixing hole on its side that passes through the receiving groove, and the second-stage rotating plate has a pin hole on its side. A fixing pin is provided on the fixing hole, and the fixing pin passes through the pin hole, so that the second-stage rotating plate is fixed to the first-stage fixed plate.
[0009] Furthermore, the support leg includes a first-stage support rod and a second-stage support rod, the upper end of the first-stage support rod is hinged to the rotary table, and the second-stage support rod is slidably disposed on the first-stage support rod.
[0010] Furthermore, the bottom of the first-stage support rod is provided with a guide block, and the guide block is provided with a first guide through hole, and the second-stage support rod slides and extends along the first guide through hole.
[0011] Furthermore, a support block is provided above the guide block, and a second guide through hole is provided on the support block, and the first-stage fixing plate is connected to the support block.
[0012] Furthermore, the bottom of the second-order support rod is provided with a tapered rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] Specifically, rotating grips are installed on the two support legs of the triangular support frame. The two grips can rotate and merge to the same side at the same time, so that the sides of the two grips abut against and wrap around the third support leg, forming an overall lock on the three support legs. When the operator holds the merged rotating grip, the mechanical constraint formed by the wrapping structure and the abutment force allows the operator to lift the three support legs and lift the entire device simultaneously with just one hand.
[0015] Addressing the pain points of traditional survey equipment where moving it requires both hands to hold the support legs or the legs are prone to falling apart due to a weak grip, this design offers three key benefits: First, the rotating grip plate's enveloping locking mechanism ensures the three support legs form a rigid whole during movement, completely preventing loosening and wobbling. Second, the grip handle design, combined with the grip plate's self-adaptive properties, significantly reduces handling fatigue. Third, the overall structure simplifies movement to a single-handed action without compromising equipment stability, greatly improving the efficiency and safety of equipment relocation during field surveys, especially adapting to the high-frequency movement needs in rugged terrain.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0021] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.
[0022] like Figures 1 to 2 As shown, this utility model provides a mobile geotechnical engineering survey measuring device, including three support legs, a rotating platform 2 mounted on the three support legs, and a measuring instrument 3 mounted on the rotating platform 2. Two of the support legs are provided with rotating grips 4, which rotate and merge to the same side, surrounding a single support leg 1, and the side of the rotating grips 4 abuts against the single support leg 1. Specifically, rotating grips 4 are respectively provided on two support legs of a triangular support frame. The two grips can rotate and merge to the same side simultaneously, so that their sides abut against and wrap around the third support leg 1, forming an overall lock on the three support legs 1. When the operator holds the merged rotating grips 4, the mechanical constraint formed by the wrapping structure and the abutment force allows the operator to lift the three support legs 1 and the entire device simultaneously with one hand.
[0023] The rotating grip 4 includes a first-stage fixed plate 41, a second-stage rotating plate 42, and a rotating shaft 43. The first-stage fixed plate 41 is fixedly connected to the support leg and has a receiving groove 44. The rotating shaft 43 is slidably disposed in the receiving groove 44, and the second-stage rotating plate 42 is rotatably connected to the rotating shaft 43. Its working principle is that the first-stage fixed plate 41 is fixedly connected to the support leg to form a stable foundation. The receiving groove 44 allows the rotating shaft 43 to slide in the groove. When not in use, the second-stage rotating plate 42 can be processed and stored in the receiving groove 44 to reduce the space occupation. The rotatable connection between the second-stage rotating plate 42 and the rotating shaft 43 gives the second-stage rotating plate 42 a degree of rotational freedom. During operation, the grip can be easily rotated and the angle changed to fit the third support leg 1. The beneficial effect of this structure is that it improves the adaptability and ease of operation of the grip, and reduces the adjustment time for the operator in complex field environments.
[0024] The front end of the second-stage rotating plate 42 is provided with a grip handle 45; the grip handle 45 significantly improves the safety and comfort of the movement process and reduces hand fatigue and the risk of slippage.
[0025] The first-stage fixing plate 41 has a fixing hole 46 through the receiving groove 44 on its side, and the second-stage rotating plate 42 has a pin hole 47 on its side. A fixing pin is provided on the fixing hole 46, and the fixing pin passes through the pin hole 47. The second-stage rotating plate 42 is fixed to the first-stage fixing plate 41. This achieves a rigid locking mechanism for the rotating grip plate 4, ensuring that the second-stage rotating plate 42 can be fixed in a fixed position when stored in the receiving groove 44 to avoid accidental loosening. Its working principle is to provide a simple and reliable fastening method by setting a fixing hole 46 through the receiving groove 44 on the side of the first-stage fixing plate 41, and setting a corresponding pin hole 47 on the side of the second-stage rotating plate 42, and using a fixing pin to pass through these holes to fix the two components to each other. The beneficial effect of this structure is that it provides a simple and reliable fastening method.
[0026] The support leg 1 includes a first-stage support rod 11 and a second-stage support rod 12. The upper end of the first-stage support rod 11 is hinged to the rotary table 2, and the second-stage support rod 12 is slidably mounted on the first-stage support rod 11. Its working principle is achieved by designing the support leg 1 as a two-section structure. The upper end of the first-stage support rod 11 is hinged to the rotary table 2, allowing for three-dimensional angle adjustment, while the second-stage support rod 12 is slidably mounted on the first-stage support rod 11 to achieve telescopic movement. The beneficial effect of this structure is that it can quickly adjust the leg length according to the terrain, extending during measurement to smoothly contact uneven ground, thereby improving the deployment flexibility and measurement accuracy of the equipment. It also simplifies the operation process and reduces the risk of the equipment tipping over due to uneven ground in the field.
[0027] The bottom of the first-stage support rod 11 is provided with a guide block 13, and the guide block 13 is provided with a first guide through hole. The second-stage support rod 12 slides and extends along the first guide through hole. Its working principle is that by installing the guide block 13 at the bottom of the first-stage support rod 11, the first guide through hole in which the second-stage support rod 12 is guided to slide and extend along its trajectory, thus limiting the direction of movement. The beneficial effect of this design is that it reduces friction and potential deformation during extension and retraction, ensures that the support leg 1 extends or retracts smoothly and reliably, thereby maintaining the overall rigidity of the device, extending the mechanical life, and improving the ability of the equipment to quickly position in different rock and soil terrains, avoiding the impact of measurement results due to the instability of the support leg 1.
[0028] A support block 5 is provided above the guide block 13. The support block 5 is provided with a second guide through hole. The first-stage fixing plate 41 is connected to the support block 5. The support plate is used to support the first-stage fixing plate 41. The second guide through hole provides a sliding channel for the second-stage support rod 12, avoiding interference between the support plate and the second-stage support rod 12.
[0029] The bottom of the second-stage support rod 12 is provided with a tapered rod 6. Its working principle is that by installing the tapered rod 6 at the bottom of the second-stage support rod 12, its pointed design can easily penetrate the soil or rock surface to achieve fixation and ensure that the device remains in place and is not disturbed by external forces during the exploration process, thereby improving the measurement accuracy and reducing the overturning accident rate. At the same time, it reduces the operator's reliance on additional auxiliary devices in harsh field conditions and improves the overall work efficiency.
