Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to an engineering measurement structure for construction engineering. Background Art

[0002] Engineering surveying refers to the process of building construction in which the plane position and elevation of the building designed on the drawings need to be laid out to the construction surface with a certain accuracy according to the design and construction requirements during the construction phase as the basis for construction. A series of measurement and control work is carried out during the construction process to guide and ensure that the construction is carried out according to the design requirements. Engineering surveying requires the use of measuring structures, such as total stations, theodolites and other instruments. The measuring structure needs to be moved multiple times when there are many measuring positions. Therefore, an engineering surveying structure with convenient movement and strong flexibility is required.

[0003] For example, a vertical measuring device for construction engineering supervision disclosed in the utility model with authorization announcement number CN220397170U is formed by rotating and folding a rotating tripod and then limiting and clamping it with a limiting assembly ring, so that three universal wheels are supported on the ground. The vertical measuring device can be easily moved by dragging the pull ring, and a stable supporting effect can be achieved by sliding the assembly pallet down into the unfolded rotating tripod support slot, with the other half in the support tripod and the assembly slot.

[0004] This prior art also has the following problems when used:

[0005] The device limits and clamps the folded rotating tripod through a limit assembly ring to fix the rotating tripod. However, when using the device, the limit assembly ring needs to be removed to separate the limit assembly ring from the rotating tripod and the device, which makes the rotating tripod easy to lose. After the device is folded, the pointed ends of the legs are exposed to the external environment, and users are prone to accidentally touch them and get hurt. Utility Model Content

The supporting tripod 3 and the rotating tripod 4 are respectively slidably connected with the T-shaped slide bar 10 through the first T-shaped slide groove 11 and the second T-shaped slide groove 12. When the rotating tripod 4 is unfolded, the rotating tripod 4 is in line with the supporting tripod 3. At this time, the first T-shaped slide groove 11 is connected with the second T-shaped slide groove 12. The T-shaped slide bar 10 is moved to make the T-shaped slide bar 10 Half of the slide bar 10 enters the second T-shaped slide groove 12, and the other half of the T-shaped slide bar 10 is inside the first T-shaped slide groove 11. The T-shaped slide bar 10 cooperates with the first T-shaped slide groove 11 and the second T-shaped slide groove 12 to make the supporting effect of the supporting tripod 3 and the rotating tripod 4 more stable. When the rotating tripod 4 is folded and close to the supporting tripod 3, the T-shaped slide bar 10 completely enters the first T-shaped slide groove 11. At this time, the rubber anti-skid layer 19 is close to the T-shaped slide bar 10, thereby fixing the position of the T-shaped slide bar 10 and preventing the T-shaped slide bar 10 from moving relative to the supporting tripod 3.

[0027] like Figure 1-Figure 4As shown, a fixing assembly is arranged below the measuring head 1, and the fixing assembly consists of a triangular fixing box 7, a knob 8, a threaded rod 13, a threaded sleeve 14, a fixing ring 15, a connecting strip 16, an inserting rod 17 and an inserting strip 18. The bottom surface of the measuring head 1 is fixedly provided with a triangular fixing box 7, the bottom surface of the triangular fixing box 7 is rotatably connected with a knob 8, and the top surface of the knob 8 is fixedly provided with a threaded rod 13, the threaded rod 13 penetrates the triangular fixing box 7, the top of the threaded rod 13 is rotatably connected with the mounting seat 2 through a bearing, and the outer side of the threaded rod 13 is threaded A threaded sleeve 14 is connected, a fixing ring 15 is fixedly arranged on the outside of the threaded rod 13, and the fixing ring 15 can limit the movement range of the threaded sleeve 14. Three connecting strips 16 are hinged on the outside of the threaded sleeve 14 in a circumferential array, and a plug rod 17 is hinged on the other end of the connecting strip 16. Three through holes adapted to the plug rod 17 are set through the outside of the triangular fixed box 7. The plug rod 17 is slidably connected to the triangular fixed box 7 through the through holes. An insert strip 18 adapted to the plug rod 17 is set on the side of the rotating tripod 4. The plug rod 17 is inserted through the plug The bar 18 is slidably connected to the rotating tripod 4. When the device needs to be folded, the rotating tripod 4 is folded inwardly and the rotating tripod 4 is close to the supporting tripod 3. Then, the supporting tripod 3 is rotated to a vertical state. The supporting tripod 3 rotates to drive the rotating tripod 4 and the leg tip 6 to rotate. The leg tip 6 never contacts the triangular fixing box 7. At this time, the rotating tripod 4 is close to the outer surface of the triangular fixing box 7, and the insertion bar 18 is connected to the through hole. The knob 8 is turned to drive the threaded sleeve 14 to move downward. At the same time, the connecting bar 16 is rotated, and the insertion rod 17 moves along the through hole to the outside of the triangular fixing box 7 until the insertion rod 17 is simultaneously extended into the insertion bar 18. The folded rotating tripod 4 can be limited and fixed to prevent the supporting tripod 3 and the rotating tripod 4 from rotating, thereby facilitating the movement of the measuring head 1. The reverse rotation of the knob 8 can drive the insertion rod 17 to move inwardly and disengage from the insertion bar 18 at the same time, thereby facilitating the unfolding of the rotating tripod 4. The fixing component is fixedly mounted on the bottom surface of the mounting seat 2, which improves the integration of the device and has the characteristics of reasonable structure and convenient use.

[0028] Specific working principle:

[0029] When the device needs to be folded, the T-shaped slide bar 10 is moved so that the T-shaped slide bar 10 completely enters the first T-shaped slide groove 11, the rotating tripod 4 is folded inwardly and the rotating tripod 4 is close to the supporting tripod 3, and then the supporting tripod 3 is rotated to a vertical state. At this time, the rotating tripod 4 is close to the outer surface of the triangular fixed box 7, and the insertion strip 18 is connected to the through hole. The knob 8 is turned to drive the threaded sleeve 14 to move downward. At the same time, the connecting strip 16 is rotated, and the insertion rod 17 moves along the through hole to the outside of the triangular fixed box 7 until the insertion rod 17 is simultaneously extended into the insertion strip 18. The folded rotating tripod 4 can be limited and fixed to prevent the supporting tripod 3 and the rotating tripod 4 from rotating. The rotating tripod 4 is folded inwardly to cooperate with the supporting tripod 3 to cover the leg tip 6, thereby preventing the user from accidentally touching the leg tip 6 and ensuring the personal safety of the user. The nylon webbing 9 is pulled in cooperation with the universal wheel 5 to move the measuring head 1 to the specified position.

[0030] When the device is in use, rotating the knob 8 in the opposite direction can drive the insertion rod 17 to move inward at the same time and disengage from the insertion strip 18, thereby unfolding the rotating tripod 4 until the rotating tripod 4 is in line with the supporting tripod 3. At this time, the first T-shaped slide groove 11 is connected to the second T-shaped slide groove 12, and the T-shaped slide bar 10 is moved so that half of the T-shaped slide bar 10 enters the second T-shaped slide groove 12, and the other half of the T-shaped slide bar 10 is inside the first T-shaped slide groove 11. The T-shaped slide bar 10 cooperates with the first T-shaped slide groove 11 and the second T-shaped slide groove 12 to make the supporting effect of the supporting tripod 3 and the rotating tripod 4 more stable.
