Description

Technical Field

[0001] This utility model belongs to the technical field of engineering surveying and mapping auxiliary devices, specifically relating to a support frame structure for surveying high slopes along a border highway. Background Technology

[0002] In engineering surveying during highway construction, precision instruments such as total stations and levels are frequently required. The surface area measurement of high slopes along highways mainly employs total station measurement and manual measuring tape measurement. The total station collects the coordinates of the slope surface point by point and then calculates the surface area through mathematical modeling. This method requires manual operation. The total station is generally mounted on a tripod, which is a supporting device for surveying instruments. It consists of three extendable and retractable support legs and a top instrument mounting platform. It can also be used to support levels and GPS receivers, providing stability and ensuring the levelness and fixation of the measuring instruments.

[0003] When triangular support frames are used on high slopes along highways, the terrain is complex and the ground may be soft soil and rocks. When the triangular support frame is opened, the bottom of the outriggers is pointed. If the pointed outriggers are inserted into the soft ground, the support frame may become unstable and tip over. When the ground is relatively soft, the contact area between the placed triangular support frame and the ground is small, and the support frame is not stable enough, so improvements are needed. When existing support frames are used on soft ground on high slopes along highways, there is a problem that the support frame does not have a design to increase the load-bearing area in contact with the ground. To address this, this application proposes a support frame structure for surveying high slopes along highways. Utility Model Content

[0004] The purpose of this utility model is to provide a support frame structure for surveying high slopes along highways, so as to solve the problem mentioned in the background art that the support frame does not have an increased contact area with the ground load.

[0015] 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.

[0016] Please see Figures 1 to 5 This utility model provides a technical solution: a support frame structure for surveying high slopes along a highway, including a hinged mounting platform 1 and support legs 2. A surveying instrument is fixed on the mounting platform 1. The three support legs 2 are spread out to form a triangular support structure, achieving the purpose of supporting the surveying instrument. The use of the triangular support frame is conventional technology and will not be described in detail here. It also includes a telescopic component, including a fixed rod 3 fixed to the bottom surface of the mounting platform 1 by screws, and a telescopic rod 4 slidably sleeved on the outside of the fixed rod 3. The telescopic rod 4 extends along the fixed rod 1... The axial movement of the fixed rod 3 can change the position of the support base 6 and the plug rod 61 at the bottom of the telescopic rod 4, thus preventing the support base 6 from affecting the retraction of the outriggers 2 when the three outriggers 2 are retracted. The position of the telescopic rod 4 is adjustable, making it easy to change the position of the support base 6. A connecting plate 41 is welded to the top of the telescopic rod 4, and a locking ring 5 is slidably sleeved on the outer side of the top of the telescopic rod 4. A locking screw 51 passes through the locking ring 5, allowing the position of the locking ring 5 to be changed manually. By tightening the locking screw 51, the rod can be locked. The locking ring 5, connecting plate 41, and telescopic rod 4 are tightened to stabilize the telescopic rod 4 and the fixed rod 3. It also includes an adjustable support assembly connected to the bottom end of the telescopic rod 4, comprising a welded support base 6 and a plug-in rod 61, and an extension plate 8 that is pulled outwards from the support base 6. A protruding plate 81 is fixed to the extension plate 8. When the support frame of this application is placed, the outriggers 2 are spread out on the ground, and the support base 6 and extension plate 8 are in contact with the ground. The support base 6 and extension plate 8 have a large contact area with the ground, providing a more stable surface. The large support surface prevents the support frame from tilting due to soft ground. It also includes a limiting component, including a fixedly connected movable cylinder 71 and connecting strip 74, a threaded connecting ring 72 and limiting post 73. By manually changing the height of the movable cylinder 71 and connecting ring 72, the limiting post 73 can penetrate the extension plate 8 or the protruding plate 81, thereby keeping the extension plate 8 stable. The position of the extension plate 8 can be manually changed, so that the extension plate 8 serves as a support point around the chassis 6, increasing the contact range with the ground.

[0017] In this embodiment, the connecting plate 41 is arc-shaped, and the outer diameter of the connecting plate 41 is the same as the outer diameter of the telescopic rod 4. The inner surface of the locking ring 5 matches the outer surface of the telescopic rod 4. The plug rod 61 is inserted into the bottom of the telescopic rod 4. A hand-tightened Torx screw of the locking plug rod 61 passes through the bottom of the telescopic rod 4, which can manually change the position of the locking ring 5. By tightening the locking screw 51, the locking ring 5, the connecting plate 41, and the telescopic rod 4 can be locked, thereby keeping the telescopic rod 4 and the fixing rod 3 stable. The telescopic rod 4 and the plug rod 61 are separate structures, which facilitates the disassembly of the plug rod 61.

[0018] In this embodiment, a slot b is provided on the bottom surface of the support base 6 for the extension plate 8 to be slidably inserted. The extension plate 8 has a fan-shaped structure and a groove a is provided on the extension plate 8 to be engaged with the support base 6. The extension plate 8 and the support base 6 are connected by a pull-out type, which can change the position of the extension plate 8 on the support base 6, thereby changing the contact range with the ground.

[0019] In this embodiment, a concave groove is formed on the surface of the support base 6, and the convex plate 81 is located in the groove. The extension plate 8, the convex plate 81, and the support base 6 are all provided with circular holes 82 for the limiting post 73 to pass through. The bottom surface of the support base 6 and the bottom surface of the extension plate 8 are flush. The support base 6 and the extension plate 8 are in surface contact with the ground, with a large contact area, which can provide a larger support surface and prevent the support frame from tilting due to the soft ground. The limiting post 73 passes through the extension plate 8 or the convex plate 81, thereby keeping the extension plate 8 stable.

[0020] Working principle and usage process of this utility model: When using surveying instruments on high slopes along the border highway, the surveying instruments are fixed on the mounting platform 1, and the three support legs 2 are spread out to form a triangular support structure to support the surveying instruments. The position of the locking ring 5 can be manually changed, and the position of the telescopic rod 4 can be changed by tightening or loosening the locking screw 51, so that the extension plate 8 and the support chassis 6 can touch the ground; The outrigger 2 spreads out on the ground, and the support base 6 and extension plate 8 touch the ground. The support base 6 and extension plate 8 are in surface contact with the ground, with a large contact area, which can provide a larger support surface and prevent the support frame from tilting due to soft ground. The positions of the movable cylinder 71 and the connecting ring 72 can be changed so that the limiting post 73 leaves the convex plate 81. After changing the position of the extension plate 8, the movable cylinder 71 and the connecting ring 72 are moved down, and the limiting post 73 penetrates the convex plate 81 and is inserted into the support chassis 6. The extension plate 8 and the supporting chassis 6 are connected by a pull-out mechanism, which can change the position of the extension plate 8 on the supporting chassis 6, thereby changing the contact range with the ground. In summary, the support frame of this application has a design that increases the load-bearing area in contact with the ground. Through the designed extension plate 8 and support chassis 6, the support chassis 6 and extension plate 8 are in surface contact with the ground, with a large contact area, which can provide a larger support surface and prevent the support frame from tilting due to soft ground. The position of extension plate 8 can also be changed to provide more support points and change the contact range with the ground.

[0021] Although embodiments of the present invention have been shown and described (see the detailed description above), 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 present invention, the scope of which is defined by the appended claims and their equivalents.
