Description

Technical Field

[0001] The utility model relates to an engineering surveying and mapping device, in particular to an auxiliary surveying and mapping device. Background Art

[0002] In traditional surveying and mapping projects, staff usually need to use a variety of measuring tools and equipment to complete the determination of accurate topographic, geomorphic, architectural and other parameters. These tools and equipment include, but are not limited to, level instruments, total stations, GPS, and laser rangefinders. These devices each have their own characteristics and can provide accurate and reliable data for surveying and mapping work under different environments and conditions.

[0003] Chinese Patent with publication number CN219954909U discloses an auxiliary surveying and mapping device for surveying and mapping projects. Through the setting of a locking device, the locking and unlocking effects of bevel gears are realized, enabling the support legs to switch between independent movement and linkage movement states, thereby improving the practicability and flexibility of the auxiliary surveying and mapping device. However, the locking device of this patent is realized by driving a locking pin to disengage from or insert into a positioning hole through a solenoid valve. This design has some problems: First, during the use of the solenoid valve, a control switch needs to be used in cooperation, and the application of the solenoid valve and the control switch results in a relatively high manufacturing cost of the locking device; Second, the solenoid valve needs to be powered on for use, which may cause inconvenience during outdoor operations.

[0004] In view of this, although the locking device of this patent improves the flexibility and practicability of the auxiliary surveying and mapping device for surveying and mapping projects to a certain extent, there are still some areas that need improvement in terms of manufacturing cost and convenience of outdoor operations. Content of the Utility Model

[0042] Embodiment 1:

[0043] Referring to Figures 1-3 , Embodiment 1 of the auxiliary surveying and mapping device of the present utility model mainly includes a surveying instrument base 2, a surveying instrument 1, and support legs 7. The surveying instrument base 2 is a support platform for the surveying instrument 1, and the surveying instrument 1 is installed on its upper surface. The surveying instrument 1 can be different types of surveying equipment such as a level, a total station, or a laser rangefinder to meet different working requirements. Several connecting ears 3 are provided. The connecting ears 3 are divided into pairs in twos and fixedly connected to the lower surface of the surveying instrument base 2. A rotating shaft 4 is rotatably connected between each pair of connecting ears 3. Both ends of the rotating shaft 4 penetrate through the two connecting ears 3 respectively and are fixedly connected with bevel gears 5 at the ends. The adjacent rotating shafts 4 are connected through the mutual meshing of the adjacent bevel gears 5 to ensure the linkage effect between the adjacent rotating shafts 4. Several support legs 7 are provided. The upper end of the support leg 7 is fixedly connected with a bushing 8. The bushing 8 is rotatably sleeved around the middle section of the rotating shaft 4 through a bearing 24, so that relative rotation can be achieved between the rotating shaft 4 and the bushing 8 through the bearing 24. The support legs 7 of the present utility model are designed to be telescopic to meet the needs of different terrains.

[0044] A positioning structure is arranged between the shaft sleeve 8 and the rotating shaft 4. The positioning structure includes a plurality of positioning grooves 6 evenly arranged along the circumferential direction of the rotating shaft on the outer wall of the middle part of the rotating shaft 4, and a positioning rod 9 embedded and installed on the shaft sleeve 8. The positioning rod 9 includes a control rod 25 and a positioning block 23, the end of the control rod 25 is connected to the middle part of the positioning block 23 to form a T-shaped structure, and a driving mechanism is installed on the control rod 25, and the positioning block 23 matches the positioning groove 6. Under the action of the driving mechanism, the support leg 7 has a linked moving state and a separate moving state.

[0045] When the support legs 7 are in a linked moving state, the positioning blocks 23 of each positioning rod 9 of the utility model are respectively embedded in one of the positioning grooves 6 of the corresponding rotating shaft 4, that is, the sleeves 8 on each support leg 7 are locked with the corresponding rotating shaft 4, so that the sleeves 8 and the rotating shaft 4 can rotate simultaneously. At this time, by flipping one of the support legs 7, the sleeves 8 on this support leg 7 and the rotating shaft 4 rotate simultaneously. Since each rotating shaft 4 is meshed through the bevel gear 5, all the sleeves 8, the rotating shaft 4 and the support legs 7 will be flipped at the same time, thereby achieving the effect of linked movement between several support legs 7; when When it is necessary to adjust the inclination angle of one supporting leg 7 separately (that is, when the supporting leg 7 is in a separate moving state), it is only necessary to remove the positioning block 23 of the corresponding positioning rod 9 from the positioning groove 6 of the corresponding rotating shaft 4, and release the lock between the sleeve 8 on the supporting leg 7 and the corresponding rotating shaft 4, so that the sleeve 8 and the rotating shaft 4 can rotate relative to each other. At this time, the inclination angle of the supporting leg 7 can be adjusted by flipping the supporting leg 7. After the adjustment is completed, it is only necessary to embed the positioning block 23 of the positioning rod 9 in one of the positioning grooves 6 again, and the adjustment process of the inclination angle of the single supporting leg 7 is completed.

[0046] Through the above operation, the utility model does not need an external power supply, and only relies on mechanical parts to achieve the effect that the supporting legs 7 can be turned over simultaneously or adjusted individually, which is flexible and convenient to use.

[0047] The driving mechanism includes a housing 10, a sliding rod 12 and a buckle cover 15. The housing 10 is fixedly connected to the sleeve 8, the positioning rod 9 is embedded in the housing 10, and a sliding through hole 11 is designed on the control rod 25 of the positioning rod 9. The sliding through hole 11 is adapted to the sliding rod 12. The sliding rod 12 is installed in the housing 10 along the axial direction of the sleeve 8, and the sliding rod 12 passes through the sliding through hole 11 on the positioning rod 9 and is slidably connected with the sliding rod 12. One end of the sliding rod 12 is close to the rotating shaft 4, and the other end is away from the rotating shaft. By sliding the sliding rod 12 back and forth along the axial direction of the sleeve 8, the positioning block 23 of the positioning rod 9 can be driven to be embedded in or out of the positioning groove 6.

[0048] To make the sliding of the sliding rod 12 smoother, an angle is provided between the control rod 25 of the positioning rod 9 and the axis of the bushing 8, and the angle is an acute angle.

[0049] Preferably, the housing 10 is designed as a cylindrical structure with an opening in the direction away from the rotating shaft 4. An installation block 26 is fixedly connected to its inner bottom surface. The control rod 25 of the positioning rod 9 is slidably connected to the installation block 26 along the radial direction of the bushing 8, and the sliding rod 12 is slidably connected to the installation block 26 along the axial direction of the bushing 8. Both ends of the sliding rod 12 are fixedly connected to two first sliders 13 respectively, and the two first sliders 13 are slidably connected to the installation block 26 along the axial direction of the bushing 8. First inclined surfaces 14 are provided at the ends of the two first sliders 13 away from each other. The two first inclined surfaces 14 are arranged in parallel, and the first inclined surface 14 close to the end of the sliding rod 12 away from the rotating shaft 4 is inclined towards the direction close to the rotating shaft 4. The buckle cover 15 is designed as a cylindrical structure with an opening in the direction close to the rotating shaft 4, and its outer side wall is slidably connected to the inner side wall of the housing 10. Two driving blocks 16 are fixedly connected to the inner side wall of the buckle cover 15, and second inclined surfaces 17 are provided at the ends of the two driving blocks 16 close to each other. These second inclined surfaces 17 are in sliding cooperation with the first inclined surfaces 14. When the buckle cover 15 and the housing 10 move away from or towards each other, one end of the positioning rod 9 can be driven to be inserted into or withdrawn from the positioning groove 6.

[0050] To make the buckling of the buckle cover 15 smooth, sliding grooves are arranged along the radial direction of the bushing 8 on the inner side wall of the housing 10, and sliding protrusions are arranged on the outer side wall of the buckle cover 15. The sliding protrusions are slidably connected to the sliding grooves. A limiting member (not shown in the figure) is provided between the housing 10 and the buckle cover 15 to prevent the buckle cover 15 from being disengaged from the housing 10.

[0051] In order to facilitate the buckle cover 15 to return to its initial position after being pressed, the present invention further provides a first elastic member 18. The first elastic member 18 is preferably a compression spring. The two ends of the first elastic member 18 are respectively connected to the inner bottom surface of the buckle cover 15 and the control rod 25 of the positioning rod 9, and are used to make the control block 23 of the positioning rod 9 enter a positioning groove 6 again under the action of the first elastic member 18 after the buckle cover 15 is released, so as to realize the locking of the bushing 8 on the support leg 7 and the corresponding rotating shaft 4.

[0052] The working principle of this embodiment:

[0053] When adjusting the angles of all the supporting legs 7 simultaneously, under the action of the first elastic member 18, the buckle cover 15 and the positioning rod 9 move away from each other. The positioning block 23 of the positioning rod 9 is embedded in the positioning groove 6. Only by flipping a single supporting leg 7 can the process of simultaneously adjusting several supporting legs 7 be realized. When it is necessary to adjust a single supporting leg 7, by pressing the buckle cover 15 of the current supporting leg 7, the buckle cover 15 approaches the housing 10. At this time, relative sliding occurs between the second inclined surface 17 of the driving block 16 and the first inclined surface 14 of the first slider 13, driving the sliding rod 12 to slide along the axial direction of the bushing 8, further driving the sliding rod 12 to slide in the sliding through hole 11, causing the positioning rod 9 to move away from the rotation axis 4, and further causing the positioning block 23 of the positioning rod 9 to disengage from the positioning groove 6. At this time, the adjustment of a single supporting leg 7 can be realized; after the adjustment is completed, stop pressing the buckle cover 15 of the current supporting leg 7. Under the action of the first elastic member 18, the buckle cover 15 moves away from the rotation axis 4, and relative sliding occurs again between the second inclined surface 17 of the driving block 16 and the first inclined surface 14 of the first slider 13, driving the sliding rod 12 to slide reversely along the axial direction of the bushing 8, further driving the positioning rod 9 to move towards the rotation axis 4, and further causing the positioning block 23 of the positioning rod 9 to be embedded in the positioning groove 6 again. At this time, the angle adjustment process of a single supporting leg 7 is completed.

[0054] Embodiment 2:

[0055] Referring to Figures 4-6 as shown, the difference between this embodiment and Embodiment 1 is that the driving structure for driving the positioning rod 9 is different.

[0056] Specifically, one end of the sliding rod 12 close to the rotation axis 4 is fixedly connected to the second slider 19. A guiding structure 20 is provided in the housing 10, and the second slider 19 is slidably connected to the guiding structure 20. A second elastic member 21 is also provided in the guiding structure 20. The second elastic member 21 is preferably a compression spring. The two ends of the second elastic member 21 are respectively connected to the end wall of the guiding structure 20 and the second slider 19, and are used to push the second slider 19 to slide the end of the sliding rod 12 close to the rotation axis 4 into the sliding through hole 11, so that the positioning block 23 of the positioning rod 9 can be embedded in the positioning groove 6. In this embodiment, the guiding structure 20 is preferably a blind hole.

[0057] For the convenience of operating the sliding rod 12, the present invention is further provided with an operating rod 22. The operating rod 22 is fixedly connected to the end of the sliding rod 12 away from the rotation axis 4 and is slidably connected to the housing 10 along the axial direction of the bushing 8.

[0058] The working principle of this embodiment:

[0059] When adjusting the angles of all the supporting legs 7 simultaneously, under the action of the second elastic member 21, the end of the sliding rod 12 close to the rotating shaft 4 slides into the sliding through-hole 11, so that the positioning block 23 of the positioning rod 9 is embedded in the positioning groove 6. Only by flipping a single supporting leg 7 can the process of simultaneously adjusting several supporting legs 7 be realized. When it is necessary to adjust a single supporting leg 7, by sliding the operating rod 22, the sliding rod 12 slides along the axial direction of the bushing 8. The end of the sliding rod 12 away from the rotating shaft 4 slides into the sliding through-hole 11 and further drives the positioning block 23 of the positioning rod 9 to disengage from the positioning groove 6. At this time, the locking of the bushing 8 and the rotating shaft 4 on this supporting leg 7 is solved, and the adjustment of a single supporting leg 7 can be realized. After the adjustment is completed, the force applied to the operating rod 22 is stopped. Under the action of the second elastic member 21, the sliding rod 12 slides reversely along the axial direction of the bushing 8, so that the end of the sliding rod 12 close to the rotating shaft 4 slides into the sliding through-hole 11, and further drives the positioning rod 9 to move towards the rotating shaft 4, so that the positioning block 23 of the positioning rod 9 is embedded in the positioning groove 6 again. At this time, the process of adjusting the angle of a single supporting leg 7 is completed.

[0060] As described above, it is only the specific implementation scheme of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art can make many possible changes and modifications to the technical scheme of the present utility model by using the technical content disclosed above, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the technical scheme of the present utility model shall fall within the protection scope of the technical scheme of the present utility model.
