Description

Technical Field

[0001] This utility model relates to surveying and mapping instruments, specifically to a portable tripod and a total station equipped with the tripod. Background Technology

[0002] A total station, also known as a total station electronic distance measuring instrument, is a high-precision surveying instrument that integrates optical, electronic, mechanical, and computer technologies. It is widely used in engineering surveying, topographic mapping, building layout, cadastral surveying, and other fields. It can simultaneously measure horizontal angles, vertical angles, and slope distances, and automatically calculates and displays data such as horizontal distance, elevation difference, and coordinates through its built-in microprocessor, enabling efficient and accurate measurement work.

[0003] Total stations require the use of a tripod to stably support them on the ground. Existing tripods suffer from mobility issues: the three supports are directly anchored to the ground, hindering movement. After measuring at one location, the tripod must be manually moved to another, resulting in high labor intensity and impacting the surveyor's efficiency. Utility Model Content

[0004] This invention provides a portable tripod and a total station equipped with the tripod. Through a specific structural design, this invention enables the tripod to be easily moved, significantly reducing labor intensity and thus improving the work efficiency of surveyors.

[0005] For the tripod bracket, the first technical solution of this utility model is as follows:

[0006] A movable triangular bracket includes a mounting base and a base, as well as a first bracket and two second brackets. The mounting base and the base are fixedly connected to form a hinged base. The base has a clearance hole in the middle, which allows external equipment connection bolts to pass through. The first bracket and the second bracket are connected to the hinged base by a hinge. The first bracket includes a first support column and a rolling wheel device located at the lower end of the first support column. The second bracket includes a second support column and a support foot located at the lower end of the second support column. The hinge includes a hinge body and a limiting block, the limiting block being located on the lower side of the base.

[0007] This invention replaces one of the support legs with a rolling wheel device. When the total station needs to be moved, the tripod can be folded up, then tilted at a certain angle so that the rolling wheel device touches the ground, while the other support legs are suspended in the air, allowing the total station to be moved. Compared to the traditional method of moving the entire total station, this is much faster and more convenient, significantly reducing labor intensity and thus improving the work efficiency of surveyors. During the process of moving the total station, after the hinge connecting the first support is rotated at a certain angle, its limiting block abuts against the lower end face of the base, forming a limit and preventing the entire support from collapsing downwards, thus facilitating smooth movement. Furthermore, after the tripod is erected, the limiting block abuts against the matching limiting pad to prevent the rolling wheel device from moving, thereby ensuring that the tripod is stably erected on the ground.

[0008] As an optimization, in the aforementioned easily movable triangular support, the rolling wheel device is a triangular wheel. When implementing this utility model, the rolling wheel device can be a single wheel structure or a triangular wheel (i.e., a ladder wheel). When the rolling wheel device is a triangular wheel, since the triangular wheel has a self-overturning function, the total station can automatically overturn obstacles and move smoothly if it encounters obstacles during movement.

[0009] As an optimization, in the aforementioned easily movable triangular support, the first support column includes a first fixed column fixedly connected to a corresponding hinge and a first extension column slidably engaged with the first fixed column. The first extension column is locked by a first locking mechanism located at the lower end of the first fixed column, and the rolling wheel device is installed at the lower end of the first extension column. The second support column includes a second fixed column fixedly connected to a corresponding hinge and a second extension column slidably engaged with the second fixed column. The second extension column is locked by a second locking mechanism located at the lower end of the second fixed column, and the support foot is installed at the lower end of the second extension column. Thus, the length of the first support column can be adjusted, its application range is wider, and it is easier to store.

[0010] Regarding the aforementioned easily movable tripod, this utility model provides a corresponding total station, the specific technical solution of which is:

[0011] The total station includes the aforementioned easily movable tripod and the total station body mounted on the tripod; the total station body is placed on a base, and its base is screwed to an external equipment connecting bolt that passes through a limiting pad and the base in sequence; the limiting pad is located on the lower side of the limiting block.

[0012] When using a total station with this type of tripod for surveying, the limiting plate's action on the upper limit block of the hinge allows the tripod to stand upright on the ground. To adjust the tripod's angle, the limiting plate can be moved by rotating the external equipment connecting bolts, causing the hinge to rotate and adjusting the tripod's angle. For relocation, simply hold the total station and pull the entire device to the designated position. During pulling, the limiting block on the hinge abuts against the base, preventing the tripod from collapsing.

[0013] Preferably, the aforementioned total station has a handle on the top of its main body. The handle, in conjunction with the caster mechanism, makes it easier to move the total station; simply grasp the handle and pull the entire device.

[0014] This utility model provides a second technical solution for a tripod under the same concept, as follows:

[0015] A portable triangular bracket includes a mounting base and a base, the mounting base and base being connected and fixed to form a hinged base. The triangular bracket also includes three second brackets, each connected to the hinged base via hinges. Each second bracket includes a second support column and a support foot located at the lower end of the second support column. Each second support column includes a second fixed column fixedly connected to a corresponding hinge and a second extension column slidably engaged with the second fixed column. The second extension column is locked by a second locking mechanism located on the second fixed column. The support foot is mounted at the lower end of the second extension column. One of the second locking mechanisms is connected to a roller device via two connecting plates. Each hinge includes a hinge body and a limiting block, the limiting block being located on the lower side of the base. The base has a clearance hole in the middle, allowing external equipment connection bolts to pass through.

[0016] This utility model provides a second technical solution for a conveniently movable tripod support. The two rolling wheel devices in this solution also enable convenient movement of the total station. This second conveniently movable tripod support, by setting two rolling wheel devices on one of the second supports, allows the rolling wheel devices to touch the ground and the supporting legs to suspend in the air when the total station needs to be moved. This pulls the total station along, making it easier and more convenient than traditionally moving the entire total station, significantly reducing labor intensity and improving the work efficiency of surveyors. During the pulling of the total station, after the hinge connecting the second support rotates at a certain angle, its limiting block abuts against the lower end face of the base, forming a limit and preventing the entire support from collapsing downwards, thus facilitating smooth movement. Furthermore, after the tripod support is erected, the limiting block abuts against the matching limiting pad, preventing the rolling wheel devices from moving and ensuring the tripod support is stably erected on the ground. When implementing this scheme, the rolling wheel device can be a single wheel structure or a triangular wheel, i.e., a ladder wheel. When the rolling wheel device is a triangular wheel, since the triangular wheel has a self-overturning function, the total station can overturn obstacles and move smoothly if it encounters obstacles during the movement.

[0017] Corresponding to the easily movable tripod support of the second technical solution, this utility model provides a total station based on the second technical solution, the specific technical solution of which is:

[0018] The total station includes a movable tripod support according to the second technical solution, and a total station body mounted on the tripod support; the total station body is placed on a base, and its base is screwed to an external equipment connecting bolt that passes through a limiting pad and the base in sequence; the limiting pad is located on the lower side of the limiting block.

[0019] Similar to the first technical solution, the total station using the second technical solution of this utility model allows for adjustment of the tripod's standing angle by rotating the external equipment connecting bolts to adjust the position of the limiting pad, thereby causing the hinge to rotate and adjusting the angle of the tripod on the ground. When movement is required, simply hold the total station body and pull the entire device to the designated position. During pulling, the upper limit block of the hinge abuts against the base, preventing the support from collapsing. Of course, to prevent the total station body from wobbling relative to the base during movement, the external equipment connecting bolts can be tightened.

[0020] Preferably, in the total station of the second technical solution described above, a handle is provided on the top of the total station body. Similar to the first technical solution, the handle is used in conjunction with a roller device to facilitate the movement of the total station.

[0021] Compared with the prior art, the beneficial effects of this utility model are: a rolling wheel device is set on one of the brackets of the tripod, which, together with a specific limiting setting, enables the tripod to stand on the ground and makes the total station easy to move. When in use, the total station body together with the tripod can be pulled to the designated position without the need for carrying, which can greatly reduce the workload and improve the work efficiency.

Detailed Implementation

[0031] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings, but this should not be construed as limiting the present utility model. Contents not described in detail in the following embodiments are all common knowledge in the art or can be implemented using conventional technical means in the art.

[0032] This utility model relates to a portable tripod and a total station equipped with the tripod, comprising two implementation methods, as detailed in the references. Figure 1-7 .

[0033] Example 1: Implementation Reference for this Example Figure 1-3 and Figure 7 .

[0034] like Figure 2 As shown, a movable triangular bracket 2 includes a mounting base 25 and a base 24, as well as a first bracket 21 and two second brackets 22. The mounting base 25 and the base 24 are fixedly connected to form a hinged base (the base 24 and the mounting base 25 are connected by bolts, which facilitates the assembly of the triangular bracket). The base 24 has a clearance hole in the middle, which allows external equipment connecting bolts 4 to pass through. The first bracket 21 and the second bracket 22 are connected to the hinged base by a hinge member 23. The first bracket 21 includes a first support column 211 and a rolling wheel device 212 located at the lower end of the first support column 211. The second bracket 22 includes a second support column 221 and a support foot 222 located at the lower end of the second support column 221. The hinge member 23 includes a hinge member body 231 and a limiting block 232, which is located on the lower side of the base 24.

[0035] This invention replaces one of the support legs 222 with a rolling wheel device 212. When the total station needs to be moved, the rolling wheel device 212 can be placed on the ground while the other support legs 222 are suspended, allowing the total station to be moved. Compared to the traditional method of moving the entire total station, this is much easier and more convenient, significantly reducing labor intensity and improving the work efficiency of surveyors. During the process of moving the total station, after the hinge 23 connecting the first bracket 21 rotates at a certain angle, the limiting block 232 on it abuts against the lower end face of the base 24, forming a limit and preventing the entire tripod 2 from collapsing downwards, thus facilitating movement. Furthermore, after the tripod 2 is erected, the limiting block 232 abuts against the matching limiting pad 3, preventing the rolling wheel device 212 from moving and ensuring the tripod 2 is stably erected on the ground. The rolling wheel device 212 can be a single wheel structure or a multi-wheel structure. Figure 2 and Figure 3 The triangular wheel shown is a ladder wheel. For example... Figure 3As shown, when the rolling wheel device 212 is a triangular wheel, it includes three wheels 2121, which are connected and fixed by a tripod 2122. The included angle of the three wheels 2121 is 120°. When the tripod 2122 is standing on the ground, any two wheels 2121 can stand on the ground simultaneously. The rolling wheel device 212 itself can rotate. If it encounters an obstacle, it can rotate to overcome the obstacle.

[0036] like Figure 2 As shown, the first support column 211 includes a first fixed column 2111 fixedly connected to a corresponding hinge member 23 and a first extension column 2112 slidably engaged with the first fixed column 2111. The first extension column 2112 is locked by a first locking mechanism 2113 located at the lower end of the first fixed column 2111. The rolling wheel device 212 is installed at the lower end of the first extension column 2112. The second support column 221 includes a second fixed column 2211 fixedly connected to a corresponding hinge member 23 and a second extension column 2212 slidably engaged with the second fixed column 2211. The second extension column 2212 is locked by a second locking mechanism 2213 located at the lower end of the second fixed column 2211. The support foot 222 is installed at the lower end of the second extension column 2212. In use, the lengths of the first support column 211 and the second support column 221 can be adjusted; this design is a conventional feature in the art.

[0037] Correspondingly, Example 1 also provides a total station, such as Figure 1 , Figure 2 , Figure 7 As shown, the total station includes the easily movable tripod 2 described in Embodiment 1, and the total station body 1 mounted on the tripod 2. The total station body 1 is placed on a base 24, and its base 11 is screwed to an external equipment connecting bolt 4 that passes through a limiting pad 3 and the base 24 in sequence. The limiting pad 3 is located below the limiting block 232. A handle 12 is provided on the top of the total station body 1. The handle 12 is used for hand gripping and, together with the rolling wheel device 212, facilitates the movement of the total station. In use, the tripod 2 is first set up on the ground, and then leveled using the adjustment knob 13 on the total station body.

[0038] Example 2: This utility model provides a second implementation method for a triangular support, the specific implementation of which is described in the following reference. Figure 1-7 .

[0039] A portable triangular support 2 includes a mounting base 25 and a base 24, which are connected and fixed to form a hinged base. The triangular support 2 also includes three second supports 22, which are connected to the hinged base via hinges 23. Each second support 22 includes a second support column 221 and a support foot 222 located at the lower end of the second support column 221. The second support column 221 includes a second fixed column 2211 fixedly connected to a corresponding hinge 23 and a second extension column 2212 slidably engaged with the second fixed column 2211. The second extension column 2212 is secured by a second locking mechanism 2 provided on the second fixed column 2211. 213 is locked, and the support foot 222 is installed at the lower end of the second extension column 2212; one of the second locking mechanisms 2213 is connected to a rolling wheel device 212 through two connecting plates 223 respectively (setting two rolling wheel devices 212 provides good stability during movement; when implementing this utility model, the main body of the connecting plate 223 and the second locking mechanism 2213 can be a single integral part or two fixedly connected parts); the hinge 23 includes a hinge body 231 and a limiting block 232, the limiting block 232 is disposed on the lower side of the base 24; the base 24 has a clearance hole in the middle, which allows the external equipment connecting bolt 4 to pass through.

[0040] The conveniently movable tripod support in Embodiment 2, by setting two rolling wheel devices 212 on one of the second supports, allows the total station to be moved when needed. The rolling wheel devices 212 are on the ground, while the support legs 222 are suspended (adjusting the second extension column 2212 retracts the support legs 222), thus pulling the total station along. Compared to the traditional method of moving the entire total station, this is much easier and more convenient, significantly reducing labor intensity and improving the work efficiency of surveyors. During the pulling of the total station, after the hinge 23 connecting the second support 22 rotates at a certain angle, the limiting block 232 on it abuts against the lower end face of the base 24, forming a limit and preventing the entire tripod support 2 from collapsing downwards, thus facilitating movement. Furthermore, after the tripod support 2 is erected, the limiting block 232 abuts against the matching limiting pad 3, preventing the rolling wheel devices 212 from moving and ensuring the tripod support 2 is stably erected on the ground. The rolling wheel device 212 can be a single wheel structure or a triangular wheel, i.e., a ladder wheel, such as... Figure 3 As shown, when the rolling wheel device 212 is a triangular wheel, it includes three wheels 2121, which are connected and fixed by a tripod 2122. The included angle of the three wheels 2121 is 120°. When the tripod 2122 is standing on the ground, any two wheels 2121 can stand on the ground simultaneously. The rolling wheel device 212 itself can rotate. If it encounters an obstacle, it can rotate to overcome the obstacle.

[0041] In Embodiment 2, the total station includes the easily movable tripod 2 described in Embodiment 2, and the total station body 1 installed on the tripod 2; the total station body 1 is placed on the base 24, and its base 11 is screwed to the external equipment connecting bolt 4 that passes through the limiting pad 3 and the base 24 in sequence; the limiting pad 3 is located on the lower side of the limiting block 232.

[0042] The total station body 1 is provided with a handle 12 on its top. The handle 12 is used for hand gripping and, together with the roller device 212, facilitates the movement of the total station. The moving method is basically the same as in Embodiment 1. The difference is that, in Embodiment 2, since three support legs 222 are retained, when movement is required, the second extension column 2212 must be adjusted to retract the support legs 222 so that the tripod can be tilted, the roller device 212 can touch the ground, and the support legs 222 can be suspended in the air.

[0043] It should be noted that the tripod of this utility model was developed to meet the needs of total station use, but it can also be used to support other equipment, such as theodolites.

[0044] The foregoing general description of the utility model and its specific embodiments should not be construed as limiting the technical solution of the utility model. Those skilled in the art, based on the disclosure of this application, can add, reduce, or combine the disclosed technical features in the foregoing general description and / or specific embodiments (including examples) without departing from the constituent elements of the utility model, to form other technical solutions within the protection scope of this utility model.
