Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to a self-stabilizing and self-balancing prism support frame for in-situ monitoring. Background Art

[0002] With the continuous development of urban infrastructure, the construction of tunnels, viaducts, and other structures in congested cities is becoming increasingly frequent. These projects, characterized by high safety requirements, limited construction space, and high risks, necessitate increasingly stringent requirements for continuous monitoring during construction. However, urban infrastructure monitoring presents challenges such as limited monitoring space, numerous vehicles, and wind load interference. Currently, when using total stations to monitor settlement and displacement, the prisms typically require manual support (due to limited space) or manual leveling after setting up a tripod. These two methods are not only time-consuming and labor-intensive, but also inherently subject to human factors such as shaking during manual support. Once the tripod is set up, it can easily become unleveled due to loads such as surrounding vehicles and wind, making it difficult to guarantee the accuracy of on-site monitoring data. Therefore, improvements are urgently needed. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a self-stabilizing and self-balancing prism support frame for in-situ monitoring, aiming to solve the problem of manual leveling after setting up a tripod when using prism measurement.

[0005] Preferably, the outer peripheral surface of the lower end of the upper connecting sleeve is provided with an external thread, the upper end of the lower connecting sleeve in the extension direction is recessed with a connecting hole, the inner peripheral wall of the connecting hole is provided with an internal thread, and the external thread is threadedly connected to the internal thread.

[0006] Preferably, the self-stabilizing and self-balancing prism support for in-situ monitoring further comprises a flexible film, which is laid on the surface of the viscous liquid.

[0007] Preferably, the three supporting legs are all hingedly connected to the connecting ring body.

[0008] Preferably, the upper connecting sleeve and the lower connecting sleeve are both made of lightweight metal material.

[0009] A method for installing a self-stabilizing, self-balancing prism support frame for in-situ monitoring comprises the following steps:

[0010] Step 1: Place the container on the ground and pour an appropriate amount of viscous liquid into the storage tank;

[0011] Step 2: Place the lower connecting sleeve and the heavy metal ball vertically in the center of the viscous liquid in the storage tank, and lay a flexible film on the viscous liquid;

[0012] Step 3: Connect the triangular support frame to the connecting ring body, and the upper connecting sleeve passes through the connecting ring body and connects to the lower connecting sleeve;

[0013] Step 4. Prop up the triangular support frame and adjust the position appropriately so that the inner wall of the connecting ring can stably surround the upper connecting sleeve on the horizontal plane. Finally, connect the prism to the upper connecting sleeve. At this time, the prism will swing back and forth along the axis of the upper connecting sleeve and adaptively adjust to balance, so that the next measurement work can be carried out.

[0014] By adopting the above scheme, the beneficial effects of the present invention are:

[0015] When the prism is installed on the upper connecting sleeve, it is connected to the lower connecting sleeve through the upper connecting sleeve. Under the driving action of the metal heavy ball set at the lower end of the lower connecting sleeve, the overall center of gravity will self-adjust in the viscous liquid in the container and adjust it to a balanced state. In this way, no manual adjustment is required, which makes it convenient to determine the setting of the measuring point and carry out the next measurement work, shortening the adjustment time of monitoring.

[0022] The present invention will be further described below with reference to the following examples. The following examples are provided only to facilitate understanding of the present invention. It should be noted that, without departing from the principles of the present invention, a number of improvements and modifications may be made to the present invention by those skilled in the art, and such improvements and modifications fall within the scope of the claims of the present invention.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, a self-stabilizing and self-balancing prism support frame for in-situ monitoring includes a triangular support frame 1, a connecting ring body 2, an upper connecting sleeve 3, a lower connecting sleeve 4, a prism 5, a heavy metal ball 6, a container 7 and a viscous liquid 8; the triangular support frame 1 has three supporting feet, one end of the three supporting feet is in contact with the ground, and the other ends of the three supporting feet are connected to the outer peripheral wall of the connecting ring body 2, the connecting ring body 2 is arranged in a circular ring shape, and the three supporting feet are arranged at intervals along the circumference of the connecting ring body 2; in order to ensure that the connecting ring body 2 can be adjusted in the vertical direction according to different test points, the three supporting feet can be telescopically arranged, for example, each supporting foot includes a plurality of connecting sections, and each connecting section is connected end to end, so that the supporting feet can be telescopically arranged.

[0025] In addition, there can be multiple ways to connect each supporting foot to the connecting ring body 2. Each supporting foot can be fixedly connected to the connecting ring body 2, for example, by using screw locking, welding, etc., or each supporting foot can be movably connected to the connecting ring body 2, for example, each supporting foot is rotatably connected to the connecting ring body 2, so that each supporting foot can be forked wider and can be more stable when supporting the connecting ring body 2.

[0026] The upper connecting sleeve 3 is passed through the inner ring of the connecting ring body 2 in the up and down directions. The upper connecting sleeve 3 can move up and down relative to the connecting ring body 2 under the restriction of the inner circumferential wall of the connecting ring body 2. The upper end of the upper connecting sleeve 3 is fixedly connected to the prism 5. At this time, the upper connecting sleeve 3 and the prism 5 are connected in a detachable manner, so that when the prism 5 support frame for in-situ monitoring is not in use, the prism 5 can be removed from the upper connecting sleeve 3 and stored separately to avoid the prism 5 falling off and being damaged.

[0027] Furthermore, the lower end of the upper connecting sleeve 3 and the upper end of the lower connecting sleeve 4 in the extension direction can be detachably connected, so that the upper connecting sleeve 3 and the lower connecting sleeve 4 can be conveniently connected and installed. After the monitoring is completed, they can be disassembled for easy storage.

[0028] The lower end of the lower connecting sleeve 4 is fixedly connected to the heavy metal ball 6, so that the prism 5 can achieve a vertical state under the action of the heavy metal ball 6. Furthermore, the container 7 has a storage groove 10 with an open end. The container 7 is placed on the ground and is located below the connecting ring body 2. The heavy metal is located in the storage groove 10. The storage groove 10 also stores a viscous liquid 8 that submerges the heavy metal ball 6. This ensures that the prism 5 can automatically balance in the viscous liquid 8 under the action of the gravity of the heavy metal ball 6. In this way, when subjected to external force, the prism 5 will not experience unstable phenomena such as shaking and vibration, which is beneficial for construction personnel to implement observation.

[0029] It should be noted that the viscous liquid 8 can be a liquid with a large damping degree such as silicone oil or glycerin. The viscous liquid 8 relies on the viscous resistance of the liquid medium to attenuate the mechanical kinetic energy of the heavy metal ball 6, thereby shortening the mechanical swing or movement time, so that the heavy metal ball 6 can reach balance by itself in the viscous liquid 8.

[0030] Example 2

[0031] On the basis of Example 1, in order to facilitate the connection between the upper connecting sleeve 3 and the lower connecting sleeve 4, the outer peripheral surface of the lower end of the upper connecting sleeve 3 is provided with an external thread, and the upper end of the lower connecting sleeve 4 in the extension direction is recessed with a connecting hole, and the inner peripheral wall of the connecting hole is provided with an internal thread, and the external thread is threadedly connected to the internal thread, so that the upper connecting sleeve 3 and the lower connecting sleeve 4 can be conveniently disassembled and assembled.

[0032] In addition, the upper connecting sleeve 3 and the lower connecting sleeve 4 are both made of lightweight metal material, so that the center of gravity of the prism 5, the upper connecting sleeve 3, the lower connecting sleeve 4 and the heavy metal ball 6 after connection is located on the heavy metal ball 6 below.

[0033] In addition, the three support legs are all hingedly connected to the connecting ring body 2, so that the triangular support frame 1 can support the connecting ring body 2 according to different areas, such as Figure 5As shown, when the tripod support frame 1 is located in a narrow area for monitoring, the supporting legs of the tripod support frame 1 can be rotated relative to the connecting ring body 2 and retracted, so that the tripod support frame 1 can be adapted to be placed in a narrow area.

[0034] It should be noted that the self-stabilizing and self-balancing prism support frame for in-situ monitoring also includes a flexible film 9, which is laid on the surface of the viscous liquid 8. The flexible film 9 can prevent the viscous liquid 8 from spilling out of the storage tank 10 of the container 7 while the heavy metal ball 6 sleeve moves freely.

[0035] Example 3

[0036] The installation steps of the self-stabilizing and self-balancing prism support for in-situ monitoring are as follows:

[0037] Step 1: Place the container 7 on the ground and pour an appropriate amount of viscous liquid 8 into the storage tank 10;

[0038] Step 2: vertically place the lower connecting sleeve 4 and the heavy metal ball 6 in the center of the viscous liquid 8 in the storage tank 10, and lay a flexible film 9 on the viscous liquid 8;

[0039] Step 3: Connect the triangular support frame 1 to the connecting ring body 2, and the upper connecting sleeve 3 passes through the connecting ring body 2 and connects to the lower connecting sleeve 4;

[0040] Step 4. Prop up the triangular support frame 1 and adjust the position appropriately so that the inner wall of the connecting ring body 2 can stably surround the upper connecting sleeve 3 on the horizontal plane. Finally, connect the prism 5 to the upper connecting sleeve 3. At this time, the prism 5 will swing back and forth along the axis of the upper connecting sleeve 3 and adaptively adjust to balance, so that the next measurement work can be carried out.
