Description

Technical Field

[0001] This utility model relates to the field of string displacement gauges, specifically to a novel string-type multi-point displacement gauge cylinder. Background Technology

[0002] String-type multi-point displacement gauges are suitable for long-term installation within structures such as earth dams, embankments, slopes, tunnels, and foundations. They measure displacement, settlement, strain, and slippage at multiple deep locations within the structure, while simultaneously measuring the temperature at the installation points. Based on the number of measurement points, they can be categorized into string-type single-point displacement gauges and string-type multi-point displacement gauges. A string-type multi-point displacement gauge is a device that simultaneously monitors multiple measurement points. It achieves multi-point monitoring of the structure by setting up multiple independent string-type single-point displacement gauges on the same plane.

[0003] Existing multi-point displacement gauges lack stability during measurement. They are basically anchored together with cement mortar, and each anchor is anchored in the same cement mortar block. The displacement inside the cement mortar block is different from the displacement of the surrounding rock, and the anchor body can also deform, causing the displacements at different points to interfere with each other. This results in a certain error between the measured value of the multi-point displacement gauge and the actual displacement.

[0004] Therefore, it is necessary to invent a new type of string-type multi-point displacement meter cylinder to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a novel string-type multi-point displacement gauge barrel. By rotating the rotating rod, the connecting rod is driven to rotate. When the connecting rod rotates, it drives the external gear to rotate. The rotation of the gear meshes with the rack, thereby pushing the rack and the insertion rod to extend to both sides of the connecting plate, so as to insert them into the soil for position locking. This reduces the disturbance of the rock and soil of the borehole wall and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel string-type multi-point displacement meter cylinder, including a cylinder body for protecting the internal measuring instrument;

The connecting rod 11 is movably connected inside the instrument connector 9, and the lower end of the connecting rod 11 is movably connected to the anchor head 14. By rotating the rotating rod 7, the connecting rod 801 is driven to rotate. When the connecting rod 801 rotates, it drives the external gear 804 to rotate. The rotation of the gear 804 meshes with the rack 805, thereby pushing the rack 805 and the insertion rod 806 to extend to both sides of the connecting plate 802, thereby inserting them into the rock and soil for position locking, reducing the disturbance of the rock and soil on the borehole wall. The anchor head 14 and the connecting rod 11 are installed inside the connecting plate 802, thereby improving the stability of the anchor head 14.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the reinforcement mechanism 8 includes a connecting rod 801, a connecting plate 802, a mounting groove 803, a gear 804, a rack 805, and an insert rod 806. The connecting rod 801 is installed at the lower end of the rotating rod 7. The connecting plate 802 is provided on the upper and lower sides of the connecting rod 801. The outer surface of the connecting plate 802 is provided with mounting grooves 803. The gear 804 is fixedly installed on the outside of the connecting rod 801. The rack 805 is movably connected to one side of the gear 804. The insert rod 806 is fixedly installed at one end of the rack 805. The rotation of the rotating rod 7 drives the connecting rod 801 and the external gear 804 to rotate. The rotation of the gear 804 pushes the rack 805 and the insert rod 806 to insert into the soil, thereby improving the overall stability.

[0033] like Figure 3 and Figure 4 As shown, the connecting rod 801 and the connecting plate 802 are equipped with a rotating shaft inside. The connecting rod 801 and the connecting plate 802 are movably connected. The connecting plate 802 is equipped with a rotating shaft inside, so that the rotation of the connecting rod 801 is not affected.

[0034] like Figure 4 As shown, gear 804 meshes with rack 805. There are two sets of connecting discs 802. The insert rods 806 inside the upper connecting disc 802 are arranged left and right, while the insert rods 806 inside the lower connecting disc 802 are arranged front and back. The insert rods 806 inside the two sets of connecting discs 802 are arranged left and right and front and back respectively, and the cross arrangement enhances stability.

[0035] like Figure 1 , Figure 5 and Figure 6As shown, the lower end of the instrument connector 9 has a first threaded groove 10 inside, the upper end of the connecting rod 11 has a first threaded post 12 fixedly installed, the lower end of the connecting rod 11 has a second threaded groove 13 inside, and the upper end of the anchor head 14 has a second threaded post 15 fixedly installed. The instrument connector 9 is threadedly connected to the connecting rod 11, and the connecting rod 11 is threadedly connected to the anchor head 14. The connecting rod 11 and the instrument connector 9 are threadedly connected, and the connecting rod 11 and the anchor head 14 are also threadedly connected. The threaded connection makes disassembly convenient and quick.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, a protective tube 16 is sleeved on the outside of the connecting rod 11. The internal dimensions of the protective tube 16 match the external dimensions of the lower end of the instrument connector 9. The lower end of the instrument connector 9 is movably sleeved with the protective tube 16. The movable sleeve of the protective tube 16 with the instrument connector 9 can protect the connecting rod 11.

[0037] The working principle of this practical application is as follows: First, the sleeve 3 is fitted onto the cylinder 1 and tightened. Then, the upper end of the connecting rod 801 is connected to the rotating rod 7. After the connection is complete, the connecting rod 11 is passed through the mounting groove 803 in the connecting plate 802. The first threaded post 12 at the upper end is aligned with the first threaded groove 10 inside the instrument connector 9 and tightened. Next, the protective tube 16 is fitted over the connecting rod 11 and movably fitted onto the lower end of the instrument connector 9. Finally, the second threaded post 15 at the upper end of the anchor head 14 is aligned with the second threaded groove 13 at the lower end of the connecting rod 11 and tightened. After assembly, the entire assembly is completed. The device is placed in the pit. Once inside, the rotating rod 7 is turned to rotate the connecting rod 801. When the connecting rod 801 rotates, it drives the external gear 804 to rotate. The rotation of the gear 804 meshes with the rack 805, thereby pushing the rack 805 and the insertion rod 806 to extend to both sides of the connecting plate 802, thus inserting them into the soil and rock for position locking. This reduces the disturbance to the soil and rock mass of the borehole wall. After that, grouting and measurement can be performed. The measured values ​​are transmitted to the external equipment through the instrument inside the cylinder 1. In this way, the use of the new string-type multi-point displacement meter cylinder is completed.
