Description

Technical Field

[0001] This utility model relates to the technical field of GPS positioning and measurement tools, specifically to a GPS positioning and measurement device for engineering applications. Background Technology

[0002] In various engineering fields, accurate positioning and measurement are key to ensuring project quality and construction efficiency. GPS positioning technology, with its significant advantages such as high precision, all-weather operation, and real-time performance, has been widely used in engineering surveying. As the core tool for achieving accurate positioning, GPS positioning and measurement devices for engineering projects play a vital role in ensuring the smooth progress of projects.

[0003] Existing GPS positioning devices generally consist of only a GPS transmitter and a support rod. When taking measurements, the support rod is placed vertically on the ground, and the measurement is then taken through the transmitter. However, engineering surveys usually require multi-point measurements, and the device is manually carried on foot during the transfer process, which is physically demanding. Furthermore, the bottom of the support rod is prone to friction with the ground during the transfer, which can damage the device and potentially affect the measurement accuracy. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing GPS positioning devices mostly consist of only a transmitter and a support rod. During measurement, they are erected on the ground, and the transfer of multiple measurement points relies on manual walking, which is laborious and the bottom of the support rod is easily damaged by friction with the ground, which may affect the measurement accuracy.

[0005] To solve the above problems, the technical solution adopted by this utility model is an engineering GPS positioning and measuring device, including a device body, the device body including a GPS measuring end and a support rod, and a moving component is provided on the outside of the support rod;

[0006] The moving component includes a fixed hoop, on the outside of which a pair of positioning shafts are symmetrically fixed. A stop block is fixed at one end of each positioning shaft. A connecting rod is rotatably provided on the outside of each pair of positioning shafts. A pair of locking rods are symmetrically fixed between the pair of connecting rods. A pedal is fixed at one end of each connecting rod. A connecting block is fixed at the other end of each connecting rod. A rotating shaft is rotatably provided on the side of the connecting block. Rollers are rotatably provided at both ends of the rotating shaft.

[0007] A second fixing hoop is provided on the outer side of the support rod above the first fixing hoop. A pair of protrusions are symmetrically fixed on the outer side of the second fixing hoop, and the sides of the protrusions are provided with locking interfaces that cooperate with the locking rod.

[0008] As a further embodiment of this invention: the card interface opening faces downwards at an angle to facilitate the engagement of the card-connecting rod.

[0009] As a further embodiment of this invention, the rotation angle of the linkage rod is less than 180 degrees, so that the locking interface can stably lock the locking rod.

[0010] As a further embodiment of this utility model, both fixing clamp one and fixing clamp two are fastened with hexagonal bolts and hexagonal nuts, which facilitates fixing them to the side of the support rod.

[0011] As a further aspect of this invention, the distance between the positioning shaft and the roller and the pedal is less than the distance between the positioning shaft and the bottom end of the support rod, which can prevent the pedal from affecting the support of the support rod during measurement.

[0012] Compared with the prior art, the advantages of this utility model are as follows: This application adds a moving component. When it is necessary to move the measuring device, the roller end can be lowered, and then the roller can be made to contact the ground. The device can be pulled diagonally to move it. During the movement, the bottom surface of the support rod is removed from the ground, so there will be no friction or wear, and it can also save some physical strength. Attached Figure Description

[0020] 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.

[0021] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0022] Combined with appendix Figure 1-3 It can be seen that the device includes a main body, which includes a GPS measuring end 1 and a support rod 2. A moving component is provided on the outside of the support rod 2. The moving component includes a fixing hoop 3. A pair of positioning shafts are symmetrically fixed on the outside of the fixing hoop 3. A stop block 4 is fixed at one end of the positioning shaft. A connecting rod 5 is rotatably provided on the outside of the pair of positioning shafts. A pair of locking rods 6 are symmetrically fixed between the pair of connecting rods 5. A pedal 7 is fixed at one end of the connecting rod 5, so that the foot pedal 7 can drive the connecting rod 5 to rotate. The rotation angle of the connecting rod 5 is less than 180 degrees, so that the locking interface 12.1 can stably lock the locking rod 6. A connecting block 8 is fixed at the other end of the connecting rod 5. A rotating shaft 9 is rotatably provided on the side of the connecting block 8. Rollers 10 are rotatably provided at both ends of the rotating shaft 9.

[0023] Combined with appendix Figure 4 It can be seen that a second fixing hoop 11 is provided on the outer side of the support rod 2 above the first fixing hoop 3. A pair of protrusions 12 are symmetrically fixed on the outer side of the second fixing hoop 11. The side of the protrusion 12 has a locking interface 12.1 that cooperates with the locking rod 6. The opening of the locking interface 12.1 faces downwards to facilitate locking the locking rod 6. The first fixing hoop 3 and the second fixing hoop 11 are both fastened with hex bolts and hex nuts to facilitate fixing them to the side of the support rod 2. The distance between the positioning shaft and the roller 10 and the pedal 7 is less than the distance between the positioning shaft and the bottom end of the support rod 2, which can prevent the pedal 7 from affecting the support of the support rod 2 during measurement.

[0024] The working principle of this application is as follows: When performing GPS positioning measurement, the roller 10 end is located above, the pedal 7 end is located below, and the locking rod 6 near the roller 10 end is locked in the locking interface 12.1 to facilitate measurement;

[0025] When the device needs to be moved, step down on the roller 10 to disengage the locking rod 6 near it from the locking interface 12.1, and then engage the locking rod 6 near the pedal 7 into the locking interface 12.1 for fixation. Then, the roller 10 can be brought into contact with the ground, and the bottom end of the support rod 2 can be lifted off the ground. The device can then be dragged for transfer.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
