Description

Technical Field

[0001] This utility model relates to the field of wire take-up technology for pile foundation multi-hole pile foundation measuring instrument. Specifically, it relates to a wire take-up device for pile foundation multi-hole pile foundation measuring instrument. Background Technology

[0002] With the increasing demands for the bearing capacity and durability of foundation piles in large-scale projects such as high-rise buildings, bridges, and docks, traditional testing methods (such as visual inspection or single-point testing) are insufficient to meet the testing needs of large-diameter, deeply buried pile foundations. Furthermore, existing technologies have adopted multi-hole pile testing instruments, which use multi-span ultrasonic technology to achieve high-precision, non-destructive testing of the internal structure of the pile.

[0003] The multi-hole pile testing instrument mainly consists of multiple radial transducers, connecting lines, and a control host. In use, multiple radial transducers are placed into the pre-embedded pipe of the pile, and then the connecting lines pull the transducers, causing them to move synchronously along the pipe. The control host then completes the testing. During the lowering or raising of the radial transducers, it is necessary to ensure that all transducers rise at the same speed and height. However, in existing technologies, a lift counter is typically used to control the position of the transducers in the pre-embedded pipe. But in the testing of large piles, multiple radial transducers are usually used simultaneously, each controlled by a separate lift counter. Furthermore, the connecting lines are often quite long, making it difficult to ensure that the lowering or raising height and speed of the multiple transducers are the same, leading to inaccurate test results.

[0004] Based on the above description, there is an urgent need for a retractable device for a multi-hole pile tracking instrument that allows for easy control of the synchronous control of the lowering or raising height and speed of the radial transducer. Utility Model Content

[0005] The purpose of this utility model is to provide a retractable device for a multi-hole pile tracing instrument, which aims to solve the technical problem that the height and speed of multiple radial transducers are difficult to synchronize when the existing multi-hole pile tracing instrument is used to test large piles.

[0006] The embodiments of this utility model are achieved through the following technical solutions:

[0015] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0016] This utility model utilizes an outer ring plate, multiple support legs, a central plate, and multiple perforated ring plates to form an integrated wire-receiving frame structure. This facilitates the vertical installation, lowering, or lifting of radial transducers at the top of the pre-embedded pipes during testing.

Detailed Implementation

[0023] The specific implementation method is described below with reference to the accompanying drawings.

[0024] Example 1

[0025] Please see Figures 1 to 5 The present invention provides the following technical solution: a retractable device for a multi-hole pile tracking instrument, which is suitable for the simultaneous detection of piles by multiple radial transducers.

[0026] Specifically, such as Figure 1 and Figure 3As shown, a multi-hole pile tracking instrument take-up device further includes multiple lead wire assemblies 1, a central plate 2, an outer ring plate 3, and multiple support legs 4; the multiple support legs 4 are spaced apart at the bottom of the outer ring plate 3 along the circumferential direction; the central plate 2 is located inside the center of the outer ring plate 3; multiple multi-hole ring plates 7 with gradually increasing inner diameters are provided between the central plate 2 and the outer ring plate 3; the multiple lead wire assemblies 1 are spaced apart along the circumferential direction of the multi-hole ring plates 7; the lead wire assemblies 1 are connected to the openings of the multi-hole ring plates 7; the central plate 2, the multiple multi-hole ring plates 7, and the outer ring plate 3 are connected by multiple radial strips 5.

[0027] In this embodiment, the outer ring plate 3, multiple support legs 4, the central plate 2, and multiple perforated ring plates 7 together constitute an integrated wire-retrieving frame structure. During use, multiple support legs 4 are installed at suitable locations according to site conditions, and the support legs 4 are screwed to the outer ring plate 3. Furthermore, multiple connecting lines connected to the main unit of the multi-hole pile monitoring instrument pass through the corresponding perforated ring plates 7 and lead wire assembly 1, and are connected to the radial transducers. At the end of the connecting lines connected to the main unit of the multi-hole pile monitoring instrument, a lifting counter and winding machine, as used in the prior art, are installed to retract and extend each connecting line, controlling the height and speed of the corresponding radial transducers. Compared with the prior art, this embodiment, through its structure... The integrated wire-receiving frame structure facilitates the vertical installation, lowering, or raising of radial transducers on the top of the pre-embedded pipes at the testing site. Furthermore, the lead wire assembly 1 guides the movement of the connecting wires, ensuring that multiple radial transducers can move at a uniform speed and maintain the same height under the action of the lifting counter and winding machine, thereby significantly improving the detection accuracy of the multi-hole pile measuring instrument. Among them, multiple lead wire assemblies 1 are spaced apart along the circumference of the multi-hole ring plate 7 to facilitate the equidistant installation of multiple connecting wires according to the size of the test pile and the position of multiple pre-embedded pipes, further ensuring the synchronous height and speed of the radial transducers during testing.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, the lead wire assembly 1 includes a lead wire cylinder 11; the lead wire cylinder 11 is erected at the end of the porous ring plate 7 away from the support leg 4; the lead wire cylinder 11 communicates with the opening of the porous ring plate 7. The lead wire assembly 1 also includes a plurality of balls 12; the middle part of the lead wire cylinder 11 is provided with an annular groove for the plurality of balls 12 to be embedded; the annular groove has an opening with a diameter smaller than the diameter of the ball 12; one end of the ball 12 protrudes through the opening. It also includes a plurality of winding machines; the center of the central plate 2 is provided with a wire-jointing opening 21; the bottom of the wire-jointing opening 21 is provided with a plurality of winding machines.

[0029] In this embodiment, the use of multiple balls 12 can reduce wear on the connecting wires and improve the wire pulling efficiency of the winding machine.

[0030] In this embodiment, the connecting wires are sequentially inserted into the lead-in cylinder 11 at the bottom of the porous ring plate 7, then exit through the opening of the porous ring plate 7, and further pass through the merging opening 21 to merge multiple connecting wires. Then, they are sequentially connected to the lifting counter, the winding machine, and the main unit of the pile borehole tracking instrument. Through this lead-in process, it is possible to ensure that the radial transducer is stably lowered or raised vertically in the pre-embedded pipe, and it is also convenient to control the height and speed of the radial transducer being lowered or raised synchronously.

[0031] In this embodiment, the sidewall of the wire connection opening 21 is provided with an arc-shaped convex wall 22; by using the arc-shaped convex wall 22, the friction force during the winding and unwinding of the connecting wire is reduced, thereby reducing the wear on the connecting wire.

[0032] Specifically, such as Figure 3 and Figure 5 As shown, it also includes multiple branching components 6; the central plate 2 has multiple positioning slots 23 spaced apart at one end near the junction hole 21 for inserting the branching components 6. The branching component 6 includes a vertical insert 61 and a horizontal cylinder 62; one end of the vertical insert 61 is embedded in the positioning slot 23; the other end of the vertical insert 61 is connected to the horizontal cylinder 62. The opening direction of the horizontal cylinder 62 is the direction of half the diameter of the junction hole 21.

[0033] In this embodiment, multiple connecting wires pass through the merging opening 21 and then through multiple branching components 6. That is, they pass through the merging opening 21 and then through the horizontal cylinder 62, and then connect to the lifting counter, the winding machine, and the main unit of the multi-hole pile tracking instrument. This wire guiding process allows the winding machine to control the tension of each connecting wire, thereby facilitating the lifting counter to accurately control the speed and length of wire winding and unwinding, and thus accurately control the height position and movement speed of each radial transducer in the pre-embedded pipe.
