Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation detection, in particular to an effective prestress detection device under a T-beam anchor. Background Art

[0002] With the rapid development of technology, the requirements for engineering quality are becoming more and more stringent. In order to ensure that the tension of bridges and other facilities meets the requirements of the corresponding specifications, it is necessary to conduct sampling inspections on the prestress under the anchor. At present, the most commonly used instrument for detecting the prestress under the anchor is the prestress under anchor detector. First, the steel strand is passed through the prestress under anchor detector, and it is imprisoned with anchors and clips. Then, the prestress under anchor detector is applied with force. By measuring the changes in force and displacement, it is confirmed whether the engineering quality meets the requirements.

[0003] Upon investigation, it was found that a Chinese invention patent application disclosed a self-balancing pile foundation detection device (publication number: CN114855896A), including an anti-choke mechanism, the anti-choke mechanism including a conical wall, a ring body fixedly connected to the top of the conical wall, a diaphragm fixedly connected to the surface of the conical wall, a magnetic ball fixedly connected to the middle position of the diaphragm surface, steel fibers arranged on the surface of the magnetic ball, the surface of the steel fibers contacting with the surface of the magnetic ball through magnetic force, the top of the ring body fixedly connected to a bottom tank, the top of the bottom tank fixedly connected to a slotted plate, the slotted plate having a slot provided inside.

[0004] Although the above patent enables the verticality detector to detect the inclination of the conical wall through the cooperation of the anti-blocking mechanism, pressure component, grouting mechanism, efficiency enhancement component and verticality detector, so that the concrete can flow easily inside the pile foundation, the manufacturing cost of the verticality detector is relatively high. The above patent is not convenient for removing the verticality detector from the concrete after the concrete is poured. If it cannot be effectively recovered after use, it will lead to high overall costs and increase the economic burden of pile foundation detection.

[0005] Therefore, the utility model provides a T-beam anchor effective prestress detection device to solve the above problems Utility Model Content

[0006] In view of the above problems in the prior art, the utility model aims to provide an effective prestress detection device under a T-beam anchor, which solves the problem that most existing prestress detection devices are inconvenient to recover the verticality detector from concrete after use.

[0007] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is as follows:

[0008] Provided is a T-beam anchor under effective prestress detection device, comprising a tapered block and a detection mechanism detachably installed at a position below the tapered block.

[0009] The detection mechanism includes a mounting shell detachably mounted below the conical block, a rotating ball rotatably mounted inside the mounting shell, a detection sensor fixedly mounted on the rotating ball for detecting verticality, and a blocking plate screwed to the end of the detection sensor away from the rotating ball. A through hole is provided on the conical block for the blocking plate to pass through, and the diameter of the through hole is consistent with the diameter of the blocking plate.

[0010] The rotating ball is provided with a limit mechanism for the limit detection sensor, so that the detection sensor can detect the state of the concrete when pouring the concrete, so as to take the concrete out from the conical block after pouring.

[0011] As a preferred technical solution of the present application, the detection mechanism also includes a threaded block fixedly mounted on the mounting shell, the threaded block being screwed to the conical block so that the mounting shell can be easily unscrewed from the conical block after the concrete is poured, thereby driving the detection sensor to be taken out synchronously.

[0012] As a preferred technical solution of the present application, the limiting mechanism includes a mounting block slidably mounted on the detection sensor, a fan-shaped block slidably mounted on the mounting block, a rotating rod rotatably mounted inside the detection sensor, an active bevel gear sleeved on the rotating rod, a threaded sleeve rotatably mounted inside the detection sensor, a driven bevel gear fixedly mounted on the threaded sleeve near one end of the rotating rod and meshing with the active bevel gear, and a threaded rod screwed inside the threaded sleeve and fixedly connected to the fan-shaped block. After concrete is poured, the mounting shell is screwed out of the conical block, driving the blocking plate to move downward, and the fan-shaped block and the mounting block remain in the accommodating portion. Then, under the action of the concrete squeezing the blocking plate, the detection sensor is rotated and the detection sensor is separated from the blocking plate, so that the detection sensor can be removed from the conical block after concrete is poured for next use.

[0013] As a preferred technical solution of the present application, a receiving portion for the fan-shaped block to slide is provided inside the conical block, so that the mounting block and the fan-shaped block can be easily retained in the receiving portion.

[0014] As a preferred technical solution of the present application, a fixed block is fixedly connected to the rotating rod, and the axis of the fixed block coincides with the axis of the rotating rod, so that the operator can easily rotate the rotating rod through the fixed block.

[0015] As a preferred technical solution of the present application, a plurality of fan-shaped blocks are provided, and the plurality of fan-shaped blocks are distributed in a circular array inside the mounting block, thereby increasing the contact area between the fan-shaped blocks and the accommodating portion and improving the stability of the mounting block in blocking concrete when cooperating with the blocking plate.

[0016] The beneficial effects of the utility model are:

[0017] The utility model has a simple structure and is easy to use. The detection sensor is limited when in use by installing the housing, the rotating rod, the threaded rod and the fan-shaped block, thereby improving the stability of the detection sensor when in use. At the same time, the detection sensor is easy to be taken out of the conical block after pouring concrete by setting the mounting block and the blocking plate. After the detection sensor is taken out, the blocking plate blocks the concrete inside the conical block, so that the concrete is not easy to flow out of the through hole.

[0026] like Figure 1 As shown, the utility model provides a T-beam anchor effective prestress detection device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the prestress detection device includes a conical block 1 and a detection mechanism 2 detachably installed at a position below the conical block 1 .

[0027] The detection mechanism 2 includes a mounting shell 21 detachably mounted at a position below the conical block 1, a rotating ball 22 rotatably mounted inside the mounting shell 21, a detection sensor 23 fixedly mounted on the rotating ball 22 for detecting verticality, and a blocking plate 24 screwed to the end of the detection sensor 23 away from the rotating ball 22. A through hole is opened on the conical block 1 for the blocking plate 24 to pass through, and the diameter of the through hole is consistent with the diameter of the blocking plate 24.

[0028] The rotating ball 22 is provided with a limit mechanism 3 for a limit detection sensor 23 .

[0029] Before pouring concrete, take the conical block 1 and install it at a predetermined position, screw the blocking plate 24 onto the detection sensor 23, then take the installation shell 21, insert the blocking plate 24 from the through hole, and then drive the detection sensor 23 into the through hole, install the installation shell 21 at the lower position of the conical block 1, and then pour concrete, so that the detection sensor 23 can easily detect the verticality of the concrete.

[0030] It should be noted that, in order to facilitate the detachable installation of the mounting shell 21 on the conical block 1 , the detection mechanism 2 further includes a threaded block 25 fixedly mounted on the mounting shell 21 , and the threaded block 25 is screwed to the conical block 1 .

[0031] When the mounting housing 21 needs to be mounted on the conical block 1 , the threaded block 25 is screwed into the conical block 1 , thereby achieving a detachable connection between the mounting housing 21 and the conical block 1 .

[0032] Furthermore, in order to facilitate the removal of the detection sensor 23 from the conical block 1 after the concrete is poured, the limiting mechanism 3 includes a mounting block 31 slidably mounted on the detection sensor 23, a sector block 32 slidably mounted on the mounting block 31, a rotating rod 33 rotatably mounted inside the detection sensor 23, an active bevel gear 35 sleeved on the rotating rod 33, a threaded sleeve 37 rotatably mounted inside the detection sensor 23, a driven bevel gear 36 fixedly mounted on the threaded sleeve 37 near one end of the rotating rod 33 and meshing with the active bevel gear 35, and a threaded rod 38 screwed inside the threaded sleeve 37 and fixedly connected to the sector block 32.

[0033] In order to accommodate the sector block 32 , a receiving portion 11 for the sector block 32 to slide is provided inside the conical block 1 .

[0034] After the mounting shell 21 is installed, the rotating rod 33 is rotated to drive the active bevel gear 35 to rotate, thereby driving the driven bevel gear 36 to rotate, and then driving the threaded sleeve 37 to rotate, so that the threaded rod 38 extends from the threaded sleeve 37, so that the fan-shaped block 32 slides on the mounting block 31, extends from the mounting block 31, and is clamped in the accommodating portion 11, thereby limiting the detection sensor 23 and making it easy for the fan-shaped block 32 to slide in the accommodating portion 11. When pouring concrete, it is easy to drive the detection sensor 23 to swing, and then drive the fan-shaped block 32 to slide in the accommodating portion 11, so that the mounting block 31 and the fan-shaped block 32 limit the detection sensor 23 while the swing of the detection sensor 23 is not easily restricted.

[0035] After the concrete is poured, the mounting shell 21 is unscrewed from the conical block 1, and the detection sensor 23 moves downward at the same time, driving the blocking plate 24 to move downward, and the fan-shaped block 32 is clamped in the accommodating portion 11, driving the mounting block 31 to remain in the accommodating portion 11. When the detection sensor 23 continues to descend and contact the mounting block 31, the mounting shell 21 is separated from the conical block 1, and then under the action of the concrete squeezing the blocking plate 24, the detection sensor 23 is rotated and screwed out of the blocking plate 24, so that the detection sensor 23 is separated from the blocking plate 24, so that the detection sensor 23 can be taken out of the conical block 1 after the concrete is poured for the next use.

[0036] Furthermore, in order to facilitate the operator to rotate the rotating rod 33 , a fixing block 34 is fixedly connected to the rotating rod 33 , and the axis of the fixing block 34 coincides with the axis of the rotating rod 33 .

[0037] When the rotating rod 33 needs to be rotated, the operator rotates the fixing block 34 to drive the rotating rod 33 to rotate, so that the operator can adjust the position of the sector block 32 by rotating the fixing block 34 .

[0038] At the same time, in order to improve the installation stability of the mounting block 31, a plurality of fan-shaped blocks 32 are provided, and the plurality of fan-shaped blocks 32 are distributed in a circular array inside the mounting block 31. By providing a plurality of fan-shaped blocks 32, the contact area between the fan-shaped blocks 32 and the accommodating portion 11 is increased, thereby improving the stability of the mounting block 31 in blocking concrete when cooperating with the blocking plate 24.

[0039] The basic principle of the prestress detection device in this embodiment is:

[0040] Before pouring concrete, take the conical block 1 and install it at a predetermined position, screw the blocking plate 24 onto the detection sensor 23, then take the installation shell 21, insert the blocking plate 24 from the through hole, install the installation shell 21 at the lower position of the conical block 1, and pour concrete.

[0041] After the concrete is poured, the mounting shell 21 is screwed out of the conical block 1, the blocking plate 24 moves downward, and the fan-shaped block 32 is clamped in the accommodating portion 11, driving the mounting block 31 to remain in the accommodating portion 11. When the detection sensor 23 continues to descend and contact the mounting block 31, the mounting shell 21 is separated from the conical block 1, and then the detection sensor 23 is rotated under the force of the concrete squeezing the blocking plate 24, and the detection sensor 23 is screwed out of the blocking plate 24, so that the detection sensor 23 is separated from the blocking plate 24, so that the detection sensor 23 can be taken out from the conical block 1 after the concrete is poured for the next use.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
