Description

Technical Field

[0001] This utility model relates to the technical field of triaxial mixing pile machines, and specifically to a drilling monitoring device for triaxial mixing pile machines. Background Technology

[0002] With the continuous development of the domestic infrastructure industry, triaxial mixing piles are often used as a foundation reinforcement and foundation pit retaining structure in urban rail transit, building construction and other technical fields. The quality of their construction will directly affect the safety of the entire foundation pit.

[0003] In conventional triaxial mixing pile construction, drilling depth is controlled by marking depth lines on the drill rod and using a stopwatch to time and calculate drilling and lifting speeds, thereby controlling construction parameters such as reinforcement depth and drilling / lifting speed. However, in complex and variable strata, where different cement dosages are used for reinforcement designs based on pit depth and geological variations, this method requires setting multiple marking lines and timing variations in drilling and lifting speeds, making it difficult to control. It also demands high skill and technical expertise from monitoring personnel, is time-consuming and labor-intensive, and the method itself is relatively outdated. Therefore, accurately, efficiently, and intelligently controlling the drilling depth and speed variations of triaxial mixing piles is a key issue that urgently needs to be addressed.

[0022] Example 1

[0023] This embodiment provides a drilling monitoring device for a triaxial mixing pile machine, which aims to solve the problem of difficulty in monitoring the drilling depth and speed of conventional triaxial mixing pile machines. (Refer to...) Figures 1-4 The specific structure of this embodiment will be described in detail below.

[0024] A drilling monitoring device for a triaxial mixing pile machine includes a support frame 1 and a monitoring component 2 movably mounted on the support frame 1;

[0025] Specifically, the monitoring component 2 includes two monitoring plates 3 arranged side by side, which are movably mounted on the support frame 1. A monitoring sensor 4 is provided on the outer side of one of the monitoring plates 3. The rotating shaft of the monitoring sensor 4 passes through one of the monitoring plates 3 and is connected to the other monitoring plate 3 through a bearing. A first roller 5 is provided on the rotating shaft between the two monitoring plates 3. A second roller 6 is provided on one side of the first roller 5. The steel cable of the three-axis mixing pile machine is passed between the first roller 5 and the second roller 6.

[0026] In this embodiment, the monitoring sensor 4 adopts the existing CJ-101 depth sensor. The monitoring sensor 4 is installed on the outer surface of a monitoring plate 3. The rotating shaft of the monitoring sensor 4 passes through a monitoring plate 3, and the end of the rotating shaft of the monitoring sensor 4 is mounted on another monitoring plate 3 through a bearing. The first roller 5 is fixedly installed on the rotating shaft of the monitoring sensor 4 between the two monitoring plates 3. The middle part of the second roller 6 is provided with a rotating shaft through a bearing, so that the second roller 6 is installed between the two monitoring plates 3 on one side of the first roller 5 through the rotating shaft. Then, the steel cable of the three-axis mixing pile machine is threaded between the first roller 5 and the second roller 6. So when the three-axis mixing pile machine is drilling, the steel cable drives the first roller 5 to rotate when drilling. The monitoring sensor 4 on the first roller 5 can accurately and efficiently monitor the drilling depth and speed of the steel cable. Finally, the monitoring sensor 4 is connected to an external computer to feed back the drilling depth of the steel cable monitored by the monitoring sensor 4 to the external computer, and at the same time obtain the drilling speed (speed = depth / unit time).

[0027] Specifically, the support frame 1 includes two base plates 11, with columns 12 respectively provided at both ends of the base plates 11; the columns 12 on the same side of the two base plates 11 are connected by a round shaft 13.

[0028] In this embodiment, the substrate 11 provides the bottom foundation support for the support frame 1. Columns 12 are respectively set at both ends of each substrate 11. At the same time, the columns 12 on the same side of the two substrates 11 are connected by a circular shaft 13, and the monitoring component 2 is movably installed between the two circular shafts 13.

[0029] Specifically, each end of the monitoring plate 3 is provided with a sleeve 31 at its top. The sleeve 31 is movably fitted onto the round shaft 13 and is provided with a locking bolt.

[0030] In this embodiment, the monitoring component 2 includes two monitoring plates 3 of the same size. A sleeve 31 is fixedly provided at both ends of each monitoring plate 3. The sleeve 31 can be movably sleeved on the round shaft 13, so that the position of the monitoring component 2 on the support frame 1 can be moved by sliding the sleeve 31 on the round shaft 13.

[0031] Furthermore, a threaded hole is provided on the sleeve 31, and a locking bolt is inserted into the threaded hole. After the sleeve 31 is moved to a suitable position, it can be fixed by the locking bolt.

[0032] Specifically, rectangular grooves 32 are provided on the inner sides of the two monitoring plates 3, and the two ends of the central shaft of the second roller 6 are rectangles that fit into the rectangular grooves 32; the two ends of the central shaft of the second roller 6 are embedded in the rectangular grooves 32.

[0033] Specifically, the two monitoring plates 3 have first threaded holes 33 on both sides, and short bolts are inserted into the first threaded holes 33. The short bolts pass through the two sides of the connecting plate 7 and are inserted into the first threaded holes 33 of the two monitoring plates 3 respectively, connecting the two monitoring plates 3.

[0034] A second threaded hole 35 extending into a rectangular groove 32 is provided on the side of the monitoring plate 3 near the second roller 6. A long bolt is inserted into the second threaded hole 35. Two long bolts pass through the connecting plate 7 and are inserted into the second threaded hole 35, and the ends of the long bolts contact the central shaft of the second roller 6.

[0035] In this embodiment, rectangular grooves 32 are provided on the inner sides of the two monitoring plates 3 to place the central shaft of the second roller 6. Both ends of the central shaft of the second roller 6 are rectangles that fit into the rectangular grooves 32, so that when the two ends of the central shaft of the second roller 6 are placed in the rectangular grooves 32, they can be easily snapped and fixed.

[0036] Meanwhile, two first threaded holes 33 are opened on both sides of the monitoring plate 3. Four short bolts are passed through the two sides of the connecting plate 7 and inserted into the first threaded holes 33 to connect the two ends of the two monitoring plates 3 respectively.

[0037] Optionally, a second threaded hole 35 is also provided on the other end of the monitoring plate 3 near the first roller 5. A long bolt is inserted into the second threaded hole 35. The long bolt passes through the connecting plate 7 and is inserted into the second threaded hole 35. By screwing the long bolt into the second threaded hole 35, the tail of the long bolt abuts against both ends of the rotating shaft in the middle of the second roller 6, causing the second roller 6 to move closer to the first roller 5. This improves the sensitivity of the steel cable clamped between the second roller 6 and the first roller 5, thereby improving the accuracy and precision of the monitoring.

[0038] Specifically, a reinforcing plate 8 is provided between the two columns 12 near the first roller 5, and a through groove 81 is provided on the reinforcing plate 8; an L-shaped limiting plate 34 is provided at the bottom of the two monitoring plates 3, and the monitoring plate 3 and the reinforcing plate 8 are connected by bolts passing through the limiting plate 34 and the through groove 81 and cooperating with nuts.

[0039] In this embodiment, an L-shaped limiting plate 34 is provided at the bottom of the two monitoring plates 3. The limiting plate 34 fits against the lower surface of the reinforcing plate 8, and a through hole that matches the through groove 81 is provided on the limiting plate 34. The limiting plate 34 and the reinforcing plate 8 are connected by bolts passing through the through hole and the through groove 81. Then, when the monitoring plate 3 moves to a suitable position, the monitoring plate 3 is fixed by the cooperation of the limiting plate 34 and the reinforcing plate 8.

[0040] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
