Description

Technical Field

[0001] This utility model relates to the field of engineering surveying auxiliary equipment technology, and in particular to a surveying support for engineering surveying. Background Technology

[0002] Engineering surveying is a field that provides accurate measurement data and technical support for various engineering projects during the planning, design, construction, and operation management stages. A surveying support for engineering surveying is a device used to support and fix surveying instruments, ensuring that the instruments maintain a stable and accurate position and orientation during the measurement process, thereby improving measurement accuracy and work efficiency.

[0003] A search revealed Chinese Patent Publication No. CN220688588U, which discloses a base frame for placing engineering surveying and mapping equipment. This base frame includes a frame plate, characterized by: a support column installed at the center of the lower part of the frame plate; three support legs hinged to the lower part of the frame plate; the tops of the three support legs being evenly distributed on a circle centered on the support column; an adjusting tube hinged to the side of the support column; an adjusting rod inserted into the adjusting tube; and the adjusting rod and adjusting tube being fixed by locking bolts installed on the circumference of the adjusting tube; the end of the adjusting rod being hinged to the support leg. The advantages of this invention are: by adjusting the angles of the three lower support legs and fixing them relative to the frame plate, it can be used for the horizontal placement of surveying and mapping instruments under various terrain conditions; the structure is simple, the adjustment and operation are convenient, and it meets the different usage requirements of surveying and mapping personnel.

[0004] However, in practical use, in the field of engineering surveying, the working environment is often complex and varied, ranging from rugged mountains and muddy swamps to undulating hills. Traditional surveying supports often suffer from unstable support due to their lack of adaptability to different terrains. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a surveying support for engineering surveying, which aims to improve the problem of unstable support caused by the lack of adaptability to different terrains.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a surveying support for engineering surveying, comprising a fixed frame, a sleeve rotatably connected to the lower surface of the fixed frame, a support leg slidably connected inside the sleeve, a fixed leg fixedly connected to the bottom end of the support leg, a cross slidably connected inside the fixed leg, a limit pin 1 provided inside the cross, the outer wall of the limit pin 1 being disposed inside the fixed leg, a connecting rod rotatably connected to the outer wall of the cross, a base 1 and a base 2 rotatably connected to the outer wall of the connecting rod 1, the outer walls of both base 1 and base 2 being rotatably connected to the outer wall of the fixed leg, a lead screw 1 threadedly connected inside the base 2, a gripping rod fixedly connected to the bottom end of the lead screw 1, and a limit component provided inside the sleeve.

[0007] The above technical solution involves multiple sets of sleeves on the outer wall of the fixed frame, allowing the outriggers to slide inside the sleeves for telescopic extension. The outriggers are fixedly connected to the fixed legs. When the bracket is used, the sliding crossbar drives the first connecting rod to rotate, which in turn drives the first base and the second base to rotate. One side of the first and the second bases rotates around the fixed legs, further enhancing the support effect. Combined with the first lead screw and the gripping rod, the gripping force is improved, thus increasing the stability of the bracket.

[0008] As a further description of the above technical solution: The limiting component includes a second limiting pin, the outer wall of which is disposed inside the sleeve, and a limiting hole is formed inside the fixing frame, with the outer wall of the second limiting pin disposed inside the limiting hole.

[0009] With the above technical solution: when the sleeve and the outrigger slide, the second limiting pin disengages from the inside of the limiting hole; when the second limiting pin is inserted into the limiting hole, the sleeve and the outrigger are relatively fixed.

[0010] As a further description of the above technical solution: A bevel gear one is rotatably connected to the upper surface of the fixed frame, a horizontal rotating platform is fixedly connected to the upper surface of the bevel gear one, and a bevel gear two is meshed with the tooth end of the bevel gear one.

[0011] Through the above technical solution: the fixed frame supports the rotation of bevel gear one, bevel gear one meshes with bevel gear two and rotates, and the horizontal rotating table rotates horizontally with bevel gear one.

[0012] As a further description of the above technical solution: A knob is fixedly connected to the outer wall of the bevel gear two. The outer wall of the knob is rotatably connected to the inside of the fixed frame. A shaft locking device is provided on the outer wall of the knob, and the outer wall of the shaft locking device is fixedly connected to the outer wall of the fixed frame.

[0013] The above technical solution involves rotating knob one to drive bevel gear two to rotate, and using a shaft locking device to restrict the rotation of knob one to prevent bevel gear two from loosening.

[0014] As a further description of the above technical solution: The horizontal rotating platform is rotatably connected to a second lead screw, and the outer wall of the second lead screw is threadedly connected to a sliding frame, the outer wall of which is slidably connected to the inside of the horizontal rotating platform.

[0015] The above technical solution involves a horizontal rotating table supporting the rotation of a second lead screw, which in turn drives the sliding frame to slide. The interior of the horizontal rotating table is provided with a sliding groove, which supports and restricts the sliding of the sliding frame.

[0016] As a further description of the above technical solution: The outer wall of the sliding frame is rotatably connected to a second connecting rod, the outer wall of the second connecting rod is rotatably connected to a vertical rotating platform, and the outer wall of the vertical rotating platform is rotatably connected to the outer wall of the horizontal rotating platform.

[0017] Through the above technical solution: when the sliding frame slides, the sliding frame drives the second connecting rod to rotate, the second connecting rod pushes and pulls the vertical rotating platform to rotate in the vertical direction, and the horizontal rotating platform supports the rotation of the vertical rotating platform.

[0018] As a further description of the above technical solution: The vertical rotating platform is rotatably connected to a knob two inside. One end of a positive and negative lead screw is fixedly connected to the outer wall of the knob two, and the other end of the positive and negative lead screw is rotatably connected to the outer wall of the vertical rotating platform.

[0019] The above technical solution involves rotating the vertical rotating table support knob two, which in turn drives the positive and negative lead screws to rotate.

[0020] As a further description of the above technical solution: The outer wall of the positive and negative lead screws is threaded with a clamping plate, and the inside of the clamping plate is slidably connected to the outer wall of the vertical rotating table.

[0021] With the above technical solution: when the positive and negative lead screws rotate, they can push the clamping plates on both sides to slide in opposite directions, and the clamping plates can fix the instrument.

[0022] This utility model has the following beneficial effects: 1. In this utility model, the height of the support can be flexibly adjusted and fixed by the telescopic design of the support legs and the limiting components. The unfolding of the base one and base two increases the ground contact area, and the gripping bar further enhances the grip on soft ground, effectively improving the stability of the support and ensuring the stability of the surveying instrument during use.

[0023] 2. In this utility model, the design of a multi-stage rotating mechanism enables flexible angle adjustment in both horizontal and vertical directions. The rotation of the horizontal rotating table, combined with the fixing function of the shaft locking device, allows for precise adjustment and locking of the horizontal angle. The vertical rotating table achieves vertical swing through a lead screw and connecting rod mechanism. At the same time, the design of the clamping plate can firmly fix the surveying instrument, ensuring the stability and measurement accuracy of the instrument after multi-angle adjustment.

[0026] 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.

[0027] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides: a surveying support for engineering surveying, including a fixed frame 1, a sleeve 2 rotatably connected to the lower surface of the fixed frame 1, a support leg 3 slidably connected inside the sleeve 2, a fixed leg 4 fixedly connected to the bottom end of the support leg 3, a cross 5 slidably connected inside the fixed leg 4, a limit pin 6 provided inside the cross 5, the outer wall of the limit pin 6 being located inside the fixed leg 4, a connecting rod 7 rotatably connected to the outer wall of the cross 5, a base 8 and a base 9 rotatably connected to the outer wall of the connecting rod 7, the outer walls of both the base 8 and the base 9 being rotatably connected to the outer wall of the fixed leg 4, a lead screw 10 threadedly connected inside the base 9, a gripping rod 11 fixedly connected to the bottom end of the lead screw 10, and a limit assembly 12 provided inside the sleeve 2; Specifically, the fixed frame 1 can rotate with the sleeve 2, and the length can be adjusted by the sliding of the support leg 3 inside the sleeve 2. The fixed leg 4 supports the sliding of the cross 5. The outer wall of the cross 5 is rotatably connected to four sets of connecting rods 1 7, which are respectively connected to two sets of bases 1 8 and base 2 9. When the cross 5 slides down, the connecting rods 1 7 drive the bases 1 8 and base 2 9 to rotate. The bases 1 8 and base 2 9 rotate around the fixed leg 4. The unfolding of the bases 1 8 and base 2 9 can increase the ground contact area. When facing soft soil, the screw rod 1 10 can be further rotated to drive the gripping rod 11 to extend into the ground, thereby enhancing the stability of the support. When the cross 5 slides up, the bases 1 8 and base 2 9 can be retracted. The height position of the cross 5 can be adjusted by the limit pin 1 6.

[0028] Reference Figure 2 The limiting component 12 includes a second limiting pin 1201. The outer wall of the second limiting pin 1201 is disposed inside the sleeve 2. A limiting hole 1202 is opened inside the fixing frame 1. The outer wall of the second limiting pin 1201 is disposed inside the limiting hole 1202. Specifically, when the sleeve 2 and the support leg 3 slide, they can be restricted by the limiting component 12. When the limiting pin 1201 passes through the sleeve 2 and enters the limiting hole 1202, the sleeve 2 and the support leg 3 cannot slide. When the limiting pin 1201 is pulled out from the inside of the limiting hole 1202, the sleeve 2 and the support leg 3 can slide and extend.

[0029] Reference Figure 4 and Figure 5 A bevel gear 13 is rotatably connected to the upper surface of the fixed frame 1. A horizontal rotating platform 14 is fixedly connected to the upper surface of the bevel gear 13. A bevel gear 15 is meshed with the tooth end of the bevel gear 13. A knob 16 is fixedly connected to the outer wall of the bevel gear 15. The outer wall of the knob 16 is rotatably connected to the inside of the fixed frame 1. A shaft locking device 17 is provided on the outer wall of the knob 16. The outer wall of the shaft locking device 17 is fixedly connected to the outer wall of the fixed frame 1. Specifically, when horizontal adjustment is required, the bevel gear 15 can be rotated by turning the knob 16. The bevel gear 15 then drives the horizontal rotating table 14 to rotate via the bevel gear 13. The horizontal angle is adjusted by rotating the horizontal rotating table 14 horizontally. The shaft locking device 17 is existing technology and can clamp the knob 16 to prevent it from becoming loose.

[0030] Reference Figure 4 and Figure 5 The horizontal rotating platform 14 is rotatably connected to a lead screw 18, and the outer wall of the lead screw 18 is threadedly connected to a sliding frame 19. The outer wall of the sliding frame 19 is slidably connected to the inside of the horizontal rotating platform 14. The outer wall of the sliding frame 19 is rotatably connected to a connecting rod 20, and the outer wall of the connecting rod 20 is rotatably connected to a vertical rotating platform 21. The outer wall of the vertical rotating platform 21 is rotatably connected to the outer wall of the horizontal rotating platform 14. Specifically, when vertical rotation is required, the sliding frame 19 can be slid by rotating the second lead screw 18, which in turn drives the second connecting rod 20 to rotate. The second connecting rod 20 then pushes the vertical rotating table 21 to swing vertically, thereby achieving vertical angle adjustment.

[0031] Reference Figure 4 and Figure 5 The interior of the vertical rotating stage 21 is rotatably connected to a knob 22. One end of a positive and negative lead screw 23 is fixedly connected to the outer wall of the knob 22, and the other end of the positive and negative lead screw 23 is rotatably connected to the outer wall of the vertical rotating stage 21. A clamping plate 24 is threadedly connected to the outer wall of the positive and negative lead screw 23, and the interior of the clamping plate 24 is slidably connected to the outer wall of the vertical rotating stage 21. Specifically, the instrument is placed on the vertical rotating stage 21, and the positive and negative lead screws 23 are rotated by rotating the knob 22. The positive and negative lead screws 23 push the clamping plate 24 to slide, and the clamping plates 24 on both sides clamp the instrument in the middle, thereby fixing the instrument on the vertical rotating stage 21.

[0032] Working principle: When using this surveying support, the height of the support needs to be adjusted according to the terrain and measurement requirements. The support can be extended and retracted by sliding the outrigger 3 inside the sleeve 2. After adjusting to the appropriate height, the limit pin 1201 is inserted into the limit hole 1202 using the limit component 12 to fix the sleeve 2 and the outrigger 3 relatively. Then, the connecting rod 7 is rotated by sliding the cross 5. The connecting rod 7 rotates the base 8 and the base 9 to ensure the stability of the support during use. By rotating the lead screw 10, the gripping rod 11 is extended into the ground, thereby improving the stability of the support and enabling it to better adapt to complex terrain. Next, the surveying instrument is placed on the vertical rotating stage 21 for fixation. Turn the knob 22 to drive the positive and negative lead screws 23 to rotate. The positive and negative lead screws 23 push the clamping plates 24 on both sides to slide in opposite directions, clamping and fixing the instrument on the vertical rotating stage 21 to ensure the stability of the instrument during the measurement process. According to the measurement requirements, the horizontal and vertical angles of the support are adjusted. When the horizontal direction needs to be adjusted, turn knob 16 to drive bevel gear 15 to rotate. Then, through the meshing of bevel gear 13 and bevel gear 15, the horizontal rotating table 14 rotates in the horizontal direction, thus adjusting the horizontal angle. After adjusting to the appropriate position, use shaft locking device 17 to lock knob 16 to prevent it from loosening and ensure that the horizontal rotating table 14 remains stable. If the vertical angle needs to be adjusted, turn lead screw 18 to push sliding frame 19 to slide in the groove inside the horizontal rotating table 14. Sliding frame 19 drives connecting rod 20 to rotate. Connecting rod 20 pushes and pulls vertical rotating table 21, causing it to rotate in the vertical direction, thus achieving vertical angle adjustment.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
