Description

Technical Field

[0001] This invention relates to the field of surveying tools, specifically a surveying instrument for surveying. Background Technology

[0002] Surveying instruments are instruments and devices designed and manufactured for surveying operations, including data acquisition, processing, and output. They are used in various orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry tasks during the planning, design, construction, and operation management phases of engineering construction. In actual surveying, the requirements for installation accuracy are very high.

[0003] Most surveying equipment used in exploration consists of a tripod and a surveying instrument. Many regions in my country, especially mountainous areas, are rich in mineral resources. However, during the surveying process, due to the rugged terrain and rocky landscape, traditional tripod legs, which are typically pointed or flat-ended for easy insertion into the ground or placement on relatively flat surfaces, cannot be properly secured in such areas, significantly impacting measurement accuracy. Furthermore, even after the surveying instrument on the tripod has been carefully leveled, instability of the legs can cause the tripod to lose support and tilt again when the worker releases their grip. During the measurement process, a gust of wind or a slight impact can cause the tripod to fall over, greatly consuming the worker's energy and potentially damaging the surveying instrument. Therefore, we propose a surveying instrument suitable for mountainous areas. Summary of the Invention

[0004] The purpose of this invention is to provide a surveying instrument for exploration, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a surveying and mapping instrument, comprising a tripod body and an upper support leg and a lower support leg mounted on the tripod body, wherein the lower support leg is hollow, and a bolt is installed between the upper support leg and the lower support leg, and the connection between the bolt and the lower support leg is provided with a thread corresponding to the bolt, and further comprising:

[0006] Rod 1, which is mounted on the tripod body;

[0007] A synchronous telescopic frame is installed on the tripod body, and the synchronous telescopic frame controls the upper support legs of the tripod to extend and retract synchronously;

[0008] A synchronous interlocking component is mounted on rod one and connected to the upper support leg;

[0009] A clamping component is mounted on the lower support leg and connected to a synchronous interlocking component. When the distance between the upper and lower support legs changes, the clamping component automatically adapts to produce a corresponding action. The synchronous interlocking component fixes the lower support leg to the edge and gap of the local stone block through the clamping component.

[0010] Preferably, the synchronous interlocking component includes a fixed seat 1 mounted on a rod 1, on which three sets of support plates are mounted opposite each other. A shaft 1 is installed through each support plate, and bevel gears are installed at both ends of the shaft 1. The bevel gears mesh with each other. The component also includes a fixed seat 2 mounted on an upper support leg, on which a fixed cylinder is mounted. A roller 1 is fitted around the fixed cylinder, and a torsion spring 1 is installed between the roller 1 and the fixed cylinder. A steel rope 1 is wound between the shaft 1 and the roller 1.

[0011] Furthermore, a limiting mechanism is installed on the synchronous interlocking component, which restricts the final position of the synchronous interlocking component.

[0012] Preferably, the limiting mechanism includes a rotating rod coaxially mounted with the shaft, a limiting hole being formed on the rotating rod, a block being mounted on the fixed base, and a limiting rod being installed through the block, the limiting rod passing through the limiting hole.

[0013] Preferably, the clamping component includes a fixed base three mounted on the lower support leg, a shaft two through which is mounted on the fixed base three, a gripper mounted on the shaft two through which the gripper is passed, a guide ring several times mounted on the fixed base three, and a locking rod mounted on the fixed base two. A rod two through which is mounted on the fixed base two, a locking groove corresponding to the locking rod is formed on the rod two, a torsion spring two is mounted on the rod two, a roller two is mounted around the torsion spring two, a steel rope two is wound between the roller two and the shaft two, the steel rope two passes through the guide ring, a polygonal block is mounted on one side of the roller two, and a polygonal groove is formed on one side of the roller two.

[0014] Preferably, there are three clamping components with identical structures, which are correspondingly installed on each upper and lower support leg.

[0015] Preferably, a magnet is installed on the lower support leg, and a magnet is installed on the back of the gripper.

[0016] Preferably, a rubber ring is installed at the connection between the block and the limiting rod.

[0017] Preferably, the fixing base is equipped with a shell, and the shell has several holes, each of which is pierced by a steel rope.

[0018] Preferably, after the torsion spring 1 and torsion spring 2 have released all their force, several turns of steel rope 1 and steel rope 2 are wound around both roller 1 and roller 2.

[0019] Preferably, one end of the torsion spring is equipped with a protrusion, and the inner wall of the roller is provided with a groove, and there are several grooves.

[0020] The present invention has at least the following beneficial effects: When fixing the surveying instrument, the distance between each lower support leg and the upper support leg can be adjusted individually so that all three lower support legs are in contact with the ground. When facing an area full of rocks, after the three lower support legs touch the ground, it is only necessary to push the second rod to engage the first and second rollers, and then rotate the rotating rod to simultaneously grab the grippers on the lower support legs to the gaps and edges of the rocks, so that the tripod is stably fixed on the terrain. It has strong stability and is more convenient for subsequent leveling of the surveying instrument. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figure 2-11 The present invention provides a technical solution: a surveying and mapping instrument, comprising a tripod body 1 and an upper support leg 11 and a lower support leg 12 mounted on the tripod body 1, wherein the lower support leg 12 is hollow, and a bolt 13 is installed between the upper support leg 11 and the lower support leg 12, and the connection between the bolt 13 and the lower support leg 12 is provided with a thread corresponding to the bolt 13, characterized in that: it further comprises:

[0036] Rod 16 is mounted on the tripod body 1.

[0037] Synchronous telescopic frame 2, which is installed on the tripod body 1, controls the upper support legs 11 of the tripod to expand and retract synchronously;

[0038] Synchronous interlocking component 3 is mounted on rod 16 and connected to upper support leg 11;

[0039] The clamping component 4 is mounted on the lower support leg 12 and is connected to the synchronous interlocking component 3. When the distance between the upper support leg 11 and the lower support leg 12 changes, the clamping component 4 automatically adapts to produce a corresponding action. The synchronous interlocking component 3 fixes the lower support leg 12 to the edge and gap of the local stone through the clamping component 4.

[0040] The synchronous telescopic frame 2 is existing technology and has been applied in this field. It mainly consists of a collar, a support rod, and a shaft, so it will not be described in detail here.

[0041] The synchronous interlocking component 3 includes a fixed seat 31 mounted on a rod 16, a support plate 32 mounted opposite to the fixed seat 31, three sets of support plates 32, a shaft 33 mounted through each support plate 32, a bevel gear 34 mounted at both ends of the shaft 33, the bevel gears 34 meshing with each other, and a fixed seat 35 mounted on an upper support leg 11, a fixed cylinder 36 mounted on the fixed seat 35, a roller 37 sleeved around the fixed cylinder 36, a torsion spring 38 installed between the roller 37 and the fixed cylinder 36, and a steel rope 39 wound between the shaft 33 and the roller 37.

[0042] Furthermore, a limiting mechanism 5 is installed on the synchronous interlocking component 3, which limits the final position of the synchronous interlocking component 3.

[0043] The fixed cylinder 36 is rigidly connected to the fixed base 35, and the fixed cylinder 36 is also rigidly connected to the torsion spring and the roller 37. When any shaft 33 rotates, the other shafts 33 are driven to rotate synchronously through the mutual transmission between the bevel gears 34. The rotation of shaft 33 drives the steel rope 39 to retract, and the retraction of the steel rope 39 drives the roller 37 to rotate.

[0044] The limiting mechanism 5 includes a rotating rod 51 coaxially mounted with shaft 33. A limiting hole 52 is provided on the rotating rod 51. A block 53 is mounted on the fixed seat 31. A limiting rod 54 is installed through the block 53 and passes through the limiting hole 52.

[0045] The rotating rod 51 makes it easier for the drive shaft 33 to rotate. After the rotating rod 51 is rotated and the gripper 43 grips the corresponding terrain, the limiting rod 54 is inserted downward into the limiting hole 52 to restrict the rotation of the rotating rod 51, thereby limiting the position of the gripper 43.

[0046] The clamping component 4 includes a fixed base 3 41 mounted on the lower support leg 12, a shaft 2 42 through which is mounted on the fixed base 3 41, a gripper 43 mounted on the shaft 2 42, the gripper 43 being penetrated by the shaft 2 42, a guide ring 44 mounted on the fixed base 3 41, and several guide rings 44. It also includes a locking rod 45 mounted on the fixed base 2 35, a rod 2 46 through which is mounted on the fixed base 2 35, a locking groove 47 corresponding to the locking rod 45 is opened on the rod 2 46, a torsion spring 2 48 is mounted on the rod 2 46, a roller 2 49 is mounted around the torsion spring 2 48, a steel rope 2 410 is wound between the roller 2 49 and the shaft 2 42, the steel rope 2 410 penetrating the guide ring 44, a polygonal block 411 is mounted on one side of the roller 2 49, and a polygonal groove 412 is opened on one side of the roller 2 37.

[0047] After placing the tripod at the surveying location, rotate bolt 13 to separate it from the upper support leg 11. Then, the lower support leg 12 can be adjusted individually. Once both lower support legs 12 touch the ground, rotate bolt 13 again to restrict the upper support leg 11. When adjusting the distance between the upper and lower support legs 11, the steel cable 410 on the roller 49 is pulled to the corresponding length. Due to the restriction of the locking rod 45 and the locking groove 47 on the rod 46, the locking rod 45 can only move horizontally and cannot rotate. The torsion spring 48 is fixedly connected to the rod 46, causing the roller 49 to receive the force of the torsion spring. Under the action of the torsion spring 48, the steel cable 410 remains taut. After the distance between the support leg 11 and the lower support leg 12 is adjusted, with the bolt 13 fixed, the push rod 46 is pushed. The push rod 46 drives the polygonal block 411 on the roller 49 to engage with the polygonal groove 412 on the roller 37. At this time, the roller 37 and the roller 49 are in a state of synchronous rotation. That is, when the shaft 33 rotates, the shaft 33 drives the roller 37 to rotate through the steel rope 39. The roller 37 drives the roller 49 to rotate. The roller 49 drives the shaft 42 to rotate through the steel rope 410. The shaft 42 drives the gripper 43 to rotate. During the rotation, the gripper 43 grabs the gaps and edges of the rocks in the terrain, so that the lower support leg 12 is stably fixed on the terrain.

[0048] There are three clamping components 4, all with the same structure, and they are installed on the upper support leg 11 and the lower support leg 12 respectively.

[0049] Example 2

[0050] Based on Embodiment 1, this application further optimizes the solution as follows:

[0051] A magnet 14 is installed on the lower support leg 12, and a magnet 25 is installed on the back of the gripper 43.

[0052] The attraction between the magnets prevents the steel cable 410 from rotating the gripper 43 when adjusting the distance between the upper support leg 11 and the lower support leg 12. When it is necessary to rotate the gripper 43, the operator can rotate the lever 51 with a force much greater than the attraction force of the magnets, or manually pull it to separate the two and make the gripper 43 rotate. Furthermore, the presence of magnets 14 and 25 ensures that the lower support leg 12 will not be disturbed when facing terrain where the gripper 43 is not needed.

[0053] A rubber ring 55 is installed at the connection between block 53 and limit rod 54.

[0054] The rubber ring 55 increases the friction between block 53 and the limiting rod 54, making the fixation more secure. When the synchronous interlocking component 3 is not used, the limiting rod 54 can also be locked onto block 53 to prevent loss.

[0055] The fixed base 31 is surrounded by a housing 300, and the housing 300 has several holes 301, all of which are pierced by steel ropes 39.

[0056] The outer casing 300 prevents external dust from entering the bevel gear 34 and also prevents the bevel gear 34 from accidentally injuring the operator during rotation. This improves the service life of the structure and enhances safety during use. The hole 301 guides the position of the steel rope 39.

[0057] After torsion spring 38 and torsion spring 48 have released all their force, several turns of steel rope 39 and steel rope 410 are wound on roller 37 and roller 49 respectively.

[0058] This allows for immediate use when adjusting the synchronization interlocking component 3.

[0059] One end of the torsion spring 48 is fitted with a protrusion 400, and the inner wall of the roller 49 is provided with a groove 401, which has several grooves.

[0060] During the adjustment of the distance between the upper support leg 11 and the lower support leg 12, if the adjustment distance is too large, the torsion spring 48 may be overloaded and damaged.

[0061] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
