Description

Technical Field

[0001] The utility model relates to the technical field of PHC pipe piles, in particular to a monitoring device for PHC pipe piles. Background Art

[0002] Pipe piles are mainly used in pile foundation projects to improve the bearing capacity of the foundation. PHC (prestressed high-strength concrete pipe piles) are commonly used now. The verticality of the pipe piles is crucial to the overall pile foundation project. Therefore, for buildings, it is also extremely important to accurately grasp the verticality of the pipe piles.

[0003] At present, there is an existing PHC pipe pile displacement monitoring device (such as patent number: CN217601420U), which discloses a PHC pipe pile displacement monitoring device, including a pipe pile, a positioning cavity is provided on the top wall of the pipe pile, a positioning column is provided on the top of the pipe pile, a threaded hole is provided on the top wall of the positioning column, a hollow hemispherical outer frame is provided on the top of the positioning column, a glass ball is fixedly installed inside the threaded hole, the interior of the glass ball is filled with a mixed liquid, and a bubble is reserved at the center position of the top of the glass ball, and the mixed liquid is composed of alcohol, glycerin, ethylene glycol and water. In the utility model, by reserving a bubble at the center position of the inner part of the glass ball, when the position of the glass ball is tilted, due to the influence of gravity, the position of the bubble will move in the opposite direction of the tilt, and because the bubble is inside the glass ball, and the interior of the glass ball is all liquid, the position of the bubble can be moved at will, which is convenient for the staff to know the tilt angle and position of the pipe pile.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: the existing monitoring device requires the operator to concentrate and observe the position of the bubble with the naked eye to determine whether the pipe pile is vertical, which is inconvenient to use. In addition, since the bubble is light in weight, it is easily affected by the friction of the glass ball wall, resulting in inaccurate monitoring. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides a monitoring device for PHC pipe piles, which solves the technical problem that the existing monitoring device requires the operator to concentrate on observing the position of the bubble with the naked eye to determine whether the pipe pile is vertical, which is inconvenient to use. In addition, since the bubble is light in weight, it is easily affected by the friction of the glass ball wall, resulting in inaccurate monitoring.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A monitoring device for PHC pipe piles comprises a top cover, a light ring is fixedly installed at the bottom end of the top cover, a bottom support is fixedly installed at the bottom end of the light ring, an arc support plate is fixedly installed inside the top cover, and an inner bracket is fixedly installed inside the top cover; an LED light strip is integrated in the light ring, a metal push rod is slidably installed at the bottom end of the arc support plate, a rubber spacer is fixedly installed at the top end of the inner bracket, a metal ring is fixedly installed at the bottom end of the inner bracket, and a spring is fixedly installed at the top end of the metal push rod; the bottom end of the metal push rod passes through the inner bracket, the rubber spacer, and the metal ring, the positive pole of the light ring is connected to the metal push rod through a wire, a metal ball is installed inside the top cover, a battery is fixedly installed at the top end of the bottom support, and an outer bracket is fixedly installed on the outer wall of the bottom support; the positive pole of the battery is connected to the metal ring through a wire, the negative pole of the battery is connected to the negative pole of the light ring through a wire, and four support rods are evenly rotatably installed at the bottom end of the outer bracket, and connecting blocks are rotatably installed at the side ends of the four support rods.

[0010] Preferably: a liquid level is fixedly mounted on the top end of the top cover, and a rotating ring is rotatably mounted on the bottom end of the bottom bracket; and a small amount of dyed glycerin and water are filled inside the liquid level.

[0011] Preferably: a threaded rod is fixedly mounted in the middle of the rotating ring, a drag plate is threadedly mounted on the outer wall of the threaded rod; the bottom end of the drag plate is rotatably connected to the top ends of the four connecting blocks.

[0012] (III) Beneficial effects

[0013] 1. Insert the outer bracket into the pipe pile mouth and rotate the rotating ring clockwise. The rotating ring will drive the threaded rod to rotate, and the drag plate connected to the threaded rod will rise. During the rising process, the drag plate will pull the side end of the support rod through the connecting block, thereby causing the support rod to rotate. The rotation of the four support rods will be opened simultaneously inside the pipe pile to complete the fixation.

If the pipe pile is in a non-vertical state, the metal ball will be separated from the metal push rod due to the impression of gravity, and the metal push rod will slide upward under the elastic force of the spring, so that the bottom end of the metal push rod will be in contact with the metal ring, so that the LED light strip integrated in the light ring will be powered on and illuminated, so that the operator can notice the status of the pipe pile in time, and judge the status of the pipe pile through the influence of gravity on the metal ball, thereby achieving the effect of being able to monitor the pipe pile conveniently and accurately.

[0021] The embodiment of the present application provides a monitoring device for PHC pipe piles, which effectively solves the existing monitoring device, which requires the operator to concentrate and observe the position of the bubble with the naked eye to determine whether the pipe pile is vertical, which is inconvenient to use. In addition, since the bubble is light in weight, it is easily affected by the friction of the glass ball wall, resulting in inaccurate monitoring. The external bracket is extended into the mouth of the pipe pile, and the rotating ring is rotated clockwise. The rotating ring will drive the threaded rod to rotate, and the threaded rod will rise through the drag plate connected by the thread. During the rising process, the drag plate will pull the side end of the support rod through the connecting block, thereby prompting the support rod to rotate. The rotation of the four support rods will simultaneously open inside the pipe pile to complete the fixation. Rotating the rotating ring counterclockwise will cause the drag plate to descend, driving the four support rods to retract inward to complete the disassembly, and the support rods are driven by rotating the rotating ring. The rotation of the device achieves the effect that the device can be quickly installed and disassembled without the aid of tools. The metal ball moves vertically downward under the influence of gravity. When the pipe pile is in a vertical state, the metal ball will slide to the top of the metal push rod through the slope of the curved support plate, which will make the metal push rod slide downward to overcome the elastic force of the spring, so that the bottom end of the connecting block will be out of contact with the metal ring, and the light ring will be powered off. If the pipe pile is in a non-vertical state, the metal ball will be separated from the metal push rod due to the impression of gravity, and the metal push rod will slide upward under the elastic force of the spring, so that the bottom end of the metal push rod will be in contact with the metal ring, thereby making the LED light strip integrated in the light ring energized and illuminated, so that the operator can notice the status of the pipe pile in time, and complete the judgment of the status of the pipe pile through the influence of gravity on the metal ball, thereby achieving the effect of being able to monitor the pipe pile conveniently and accurately.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the existing monitoring device requires the operator to concentrate on observing the position of the bubble with the naked eye to determine whether the pipe pile is vertical, which is inconvenient to use. In addition, since the bubble is light in weight, it is easily affected by the friction of the glass ball wall, resulting in inaccurate monitoring. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a monitoring device for PHC pipe piles, comprising a top cover 1, a light ring 2 is fixedly installed on the bottom end of the top cover 1, a bottom support 3 is fixedly installed on the bottom end of the light ring 2, an arc support plate 5 is fixedly installed inside the top cover 1, and an inner bracket 4 is fixedly installed inside the top cover 1; an LED light strip is integrated in the light ring 2, a metal top rod 6 is slidably installed on the bottom end of the arc support plate 5, a rubber spacer 18 is fixedly installed on the top end of the inner bracket 4, and a metal ring 19 is fixedly installed on the bottom end of the inner bracket 4.

[0025] A spring 17 is fixedly installed on the top of the metal ring 19; the bottom end of the metal push rod 6 passes through the inner bracket 4, the rubber spacer 18, and the metal ring 19; the positive pole of the light ring 2 is connected to the metal push rod 6 through a wire; a metal ball 7 is installed inside the top cover 1; a battery 8 is fixedly installed on the top of the bottom bracket 3; an outer bracket 11 is fixedly installed on the outer wall of the bottom bracket 3; the positive pole of the battery 8 is connected to the metal ring 19 through a wire, and the negative pole of the battery 8 is connected to the negative pole of the light ring 2 through a wire.

[0026] Four support rods 15 are evenly rotatably installed at the bottom end of the outer bracket 11, and connecting blocks 16 are rotatably installed on the side ends of the four support rods 15. A liquid level 9 is fixedly installed on the top end of the top cover 1, and a rotating ring 12 is rotatably installed on the bottom end of the bottom bracket 3; the interior of the liquid level 9 is filled with a small amount of dyed glycerin and water, a threaded rod 13 is fixedly installed in the middle of the rotating ring 12, and a drag plate 14 is threadedly installed on the outer side wall of the threaded rod 13; the bottom end of the drag plate 14 is rotatably connected to the top ends of the four connecting blocks 16.

[0027] Working principle:

[0028] The first step is to extend the outer bracket 11 into the pipe pile mouth and rotate the rotating ring 12 clockwise. The rotating ring 12 will drive the threaded rod 13 to rotate, and the threaded rod 13 will rise through the drag plate 14 connected by threads. During the rising process, the drag plate 14 will pull the side end of the support rod 15 through the connecting block 16, thereby prompting the support rod 15 to rotate. The rotation of the four support rods 15 will simultaneously open inside the pipe pile to complete the fixation. Rotating the rotating ring 12 counterclockwise will prompt the drag plate 14 to descend, driving the four support rods 15 to retract inward to complete the disassembly. By rotating the rotating ring 12 to drive the rotation of the support rod 15, the effect of enabling the device to be quickly installed and disassembled without the aid of tools is achieved.

[0029] In the second step, during use, the metal ball 7 is affected by gravity and moves vertically downward. When the pipe pile is in a vertical state, the metal ball 7 will slide to the top of the metal push rod 6 through the slope of the curved support plate 5, which will make the metal push rod 6 overcome the elastic force of the spring 17 and slide downward, so that the bottom end of the connecting block 16 is out of contact with the metal ring 19, and the light ring 2 is powered off. If the pipe pile is in a non-vertical state, the metal ball 7 will be separated from the metal push rod 6 by the impression of gravity, and the metal push rod 6 will slide upward under the elastic force of the spring 17, so that the bottom end of the metal push rod 6 is in contact with the metal ring 19, so that the LED light strip integrated in the light ring 2 is powered on and illuminated, so that the operator can notice the state of the pipe pile in time, and judge the direction of the pipe pile deviation through the liquid level 9 at the top, and complete the judgment of the state of the pipe pile through the influence of gravity on the metal ball 7, thereby achieving the effect of being able to monitor the pipe pile conveniently and accurately.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
