Description

Technical Field

[0001] This utility model relates to the field of engineering construction equipment technology, specifically a modular splicing temporary control point device. Background Technology

[0002] Temporary control point devices refer to temporary equipment or structures designed to meet short-term positioning, monitoring, or control needs in engineering construction or surveying scenarios. In scenarios such as tunnels and culverts, they serve as temporary measurement reference points for rapid point transfer or transmission of coordinate information, reducing angle and side measurement errors.

[0003] In real-world applications, temporary control point devices are often designed as a single unit to minimize component wear and tear during fixed installation. However, this makes it difficult to disassemble and reuse the device after installation, thus increasing overall costs. Therefore, a modular, modular temporary control point device is needed.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is a modular splicing temporary control point device, comprising:

[0029] Embedded sleeve 1;

[0030] Embedded sleeve 1 is used for pre-embedding in concrete or other base surfaces;

[0031] Insert pipe 2, the bottom end of insert pipe 2 is engaged inside the pre-embedded sleeve 1;

[0032] The fixing component 3 includes a vertical rod 31, a push block 32, a connecting block 33, four connecting rods 37, two mounting rods 34, and two elastic blocks 35;

[0033] The top end of the insertion pipe 2 is penetrated through the outer wall of the vertical rod 31. The bottom end of the push block 32 is fixedly set at the top end of the vertical rod 31. The top end of the connecting block 33 is fixedly set at the bottom end of the vertical rod 31. One end of each of the four connecting rods 37 is rotatably set on both sides of the connecting block 33. The two sides of the outer wall of the two mounting rods 34 are rotatably set on the other side of each of the four connecting rods 37. The bottom ends of the two elastic blocks 35 are fixedly set at the top end of the outer wall of the two mounting rods 34.

[0034] The vertical rod 31 is slidably connected to the top of the insertion tube 2, and the elastic block 35 is used to limit and fix the insertion tube 2.

[0035] A spring 36 is fixedly provided at the bottom end of the connecting block 33, and the bottom end of the spring 36 is fixedly provided at the inner bottom end of the insertion tube 2;

[0036] Spring 36 is used to assist in fixing the connection between the insertion tube 2 and the pre-embedded sleeve 1, thereby improving the firmness of the connection between the two.

[0037] The outer walls of the mounting rod 34 penetrate the outer walls of the insertion pipe 2 and the pre-embedded sleeve 1, respectively.

[0038] The outer wall of the mounting rod 34 is inserted and connected to the outer walls of the insertion pipe 2 and the pre-embedded sleeve 1. Both sides of the outer walls of the insertion pipe 2 and the pre-embedded sleeve 1 are provided with mounting holes that are compatible with the mounting rod 34. When the spring 36 is in the normal state, the end of the mounting rod 34 is located in the mounting hole of the insertion pipe 2 and does not contact the pre-embedded sleeve 1.

[0039] A horizontal plate 4 is fixedly provided at the top of the outer wall of the insertion tube 2. An adjustment component 5 is provided on the horizontal plate 4, and a measuring label 6 is connected through the adjustment component 5.

[0040] Working principle: When fixing the temporary control point device, the pre-embedded sleeve 1 of the temporary control point device is first pre-embedded on the measuring base surface. Then, the insertion tube 2 is inserted into the pre-embedded sleeve 1 and the pressing block 32 is pressed down. The pressing block 32 moves downward and drives the connecting block 33 to move downward through the vertical rod 31. The downward movement of the connecting block 33 compresses the spring 36. At the same time, the downward movement of the connecting block 33 drives the two mounting rods 34 to move outward through the connecting rod 37. While pressing the pressing block 32, the insertion tube 2 is rotated until the elastic block 35 on the mounting rod 34 passes through the pre-embedded sleeve 1 to its outside, thereby installing and fixing the temporary control point device. When disassembling, the elastic block 35 is pressed inward. Under the elastic action of the spring 36, the two mounting rods 34 move inward and reset. Then, the insertion tube 2 is taken out upward. Through this splicing structure, after the temporary control point device is installed and fixed, it is easy to disassemble and reuse, thereby reducing the overall cost.

[0041] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0042] Adjustment assembly 5 includes lead screw 51, torque 52 and mounting plate 53;

[0043] The top end of the outer wall of the lead screw 51 passes through the top end of the horizontal plate 4, the bottom end of the knob 52 is fixedly set at the top end of the lead screw 51, the inner wall of the mounting plate 53 is threaded on the outer wall of the lead screw 51, and one side of the mounting plate 53 is fixedly connected to the back of the measuring label 6.

[0044] The lead screw 51 is connected to the bearing of the horizontal plate 4, and the outer wall of the knob 52 is provided with anti-slip threads to facilitate the rotation of the knob 52.

[0045] A limiting block 54 is fixedly provided at the bottom end of the lead screw 51, and the bottom end of the limiting block 54 contacts the top end of the pre-embedded sleeve 1.

[0046] The limiting block 54 is used to limit the movement of the mounting plate 53 to prevent it from moving out of the screw 51. At the same time, the limiting block 54 can also limit the insertion when the insertion pipe 2 is inserted into the pre-embedded sleeve 1 to ensure that the mounting rod 34 and the mounting hole on the pre-embedded sleeve 1 are on the same horizontal plane.

[0047] A slider 55 is fixedly provided on the other side of the mounting plate 53, and the outer wall of the slider 55 is slidably connected to the outer wall of the insertion tube 2.

[0048] The slider 55 is used to limit the movement of the mounting plate 53 so that it can move vertically. The outer wall of the insertion pipe 2 is provided with a groove that matches the slider 55.

[0049] Working principle: After the insertion pipe 2 is connected and fixed to the pre-embedded sleeve 1, rotate the knob 52. The rotation of the knob 52 drives the lead screw 51 to rotate. The rotation of the lead screw 51 drives the mounting plate 53 to move up and down until the measuring label 6 moves up and down to the appropriate position. In this way, it is easy to adjust the position and height of the measuring label 6 to meet the usage requirements of different scenarios.
