Description

Technical Field

[0001] The utility model belongs to the technical field of engineering measurement, and in particular relates to a pile hole depth detection device. Background Art

[0002] Pile holes, also called foundation pile holes, are holes drilled for pouring concrete piles in order to reinforce underground foundations and improve the bearing capacity and earthquake resistance of building foundations. In order to ensure that the depth of the pile holes meets the set requirements, the depth of the pile holes needs to be measured.

[0003] A Chinese patent with announcement number CN218522657U discloses a pile foundation hole depth measuring tool. When the winding device in this scheme reels in the measuring line, the mud attached to the measuring line will be cleaned by an annular brush to reduce the hardening of the measuring line surface. At the same time, the graphite in the graphite box is attached to the surface of the measuring line to lubricate the surface of the measuring line. In addition, a braking unit is provided to ensure that the measuring line is in a stable state after the line is lowered into place, thereby avoiding self-release and causing inconvenience in measuring the length of the lowered measuring line.

[0004] However, in actual use, the above solution needs to be supported and fixed by three support frames on the bottom circumference, and leveled by adjustment bolts on the support frames. Although it can support and fix the measuring tool, the three support frames are welded to the mounting ring of the bracket, which makes the three support frames unable to shrink, causing the device to occupy a large space during transportation, making the device inconvenient to transport. Utility Model Content

[0005] The utility model aims to provide a pile hole depth detection device to solve the problem that the prior art is inconvenient to transport.

[0006] In order to achieve the above object, the utility model provides the following technical solutions: a pile hole depth detection device, comprising

[0007] A storage bin, in which a wire-laying and measuring mechanism is installed, and a cleaning mechanism is installed at the lower end of the storage bin;

[0008] A support mechanism, the support mechanism includes a driving ring, a fixed ring and a plurality of driving rods arranged at intervals along the circumference of the storage bin, the driving ring is slidably sleeved outside the storage bin, the fixed ring sleeve is fixed outside the storage bin and is located below the driving ring, the fixed ring has a stepped shape, the driving rod includes an active rod, a driven rod, a limit plate and a telescopic rod, the top of the active rod is hinged to the bottom of the driving ring, one end of the driven rod is hinged to the side wall of the fixed ring, the bottom of the active rod is hinged to the rod body of the driven rod, the limit plate has an L-shaped shape, and one end is fixed to the bottom of the driven rod away from the storage bin, the telescopic rod is hinged to the side wall of the limit plate close to the storage bin, and the telescopic rod abuts against the end of the limit plate away from the driven rod;

[0009] The limiting mechanism is installed on the driving ring.

[0010] The principle and effect of this technical solution:

[0011] 1. The depth of the pile hole is measured by the laying-out measuring mechanism, and the line is cleaned by the cleaning mechanism. The position of the storage bin is fixed by the supporting mechanism, and the supporting mechanism is limited by the limiting mechanism, so that the device can operate stably.

[0012] 2. A crank slider mechanism is formed by hinged connection between the driving ring and the active rod, between the active rod and the driven rod, and between the driven rod and the fixed ring. By changing the position of the driving ring, the active rod can be controlled to drive the driven rod to change position, so that the support mechanism can be retracted, saving space during transportation and improving space utilization.

[0013] 3. By connecting the driven rod to the side wall of the fixed ring, when the active rod drives the driven rod to rotate around the side wall of the fixed ring, it can be limited by the step surface of the fixed ring, so that the driven rod can only rotate to the horizontal and vertical positions, thereby limiting the rotation angle of the driven rod, and limiting the position of the driving ring by the limiting mechanism, that is, the driven rod can be stably in the horizontal position, and because the telescopic rod is hinged to the side wall of the limiting plate, the telescopic rod can rotate around the limiting plate, so that the telescopic rod is rotated to an obtuse angle with the driven rod, and the telescopic rod is also limited by the contact of the end of the limiting plate. At this time, the device is placed on the ground. Because the angle between the telescopic rod and the driven rod is an obtuse angle, gravity will only drive the telescopic rod to rotate in the direction of expanding the obtuse angle, and because it is limited by the limiting plate, the telescopic rod can no longer rotate, thereby providing a stable support for the storage bin, and by adjusting the length of each telescopic rod, the storage bin can be kept in a horizontal state, thereby improving the detection accuracy.

[0014] The utility model is further configured as follows: a moving wheel is installed at the bottom of the telescopic rod.

[0015] The principle and effect of the technical solution are as follows: when the telescopic rod is in contact with the ground, the setting of the moving wheel can reduce the friction between the telescopic rod and the ground, so that when the telescopic rod rotates relative to the ground and the driven rod, the resistance encountered is smaller, that is, the telescopic rod can be more easily rotated to abut against the limit plate, that is, the angle between the telescopic rod and the driven rod reaches an obtuse angle, that is, the setting of the moving wheel makes it easier to adjust the device to a stable placement state.

[0016] The utility model is further configured as follows: the limiting mechanism includes two symmetrically arranged limiting units, the limiting unit includes a limiting cylinder, an insertion rod, a limiting spring, a slider and a pull ring, the limiting cylinder is fixed on the driving ring and is in sliding contact with the storage bin, one end of the insertion rod is slidably inserted in the limiting cylinder, the slider is slidably arranged in the limiting cylinder and is fixed on the insertion rod, the pull ring is fixed to the end of the insertion rod away from the storage bin, the limiting spring is installed in the limiting cylinder and is located on the side of the slider away from the storage bin, and a limiting hole matching the insertion rod is opened on the outer wall of the storage bin.

[0017] The principle and effect of this technical solution: when the position of the driving rod is changed by driving the driving ring, the position of the limiting unit can be changed accordingly, and through the effect of the rebound force of the limiting spring, the slider is affected by the rebound force and spontaneously drives the insertion rod to move toward the storage bin, and when the insertion rod corresponds to the limiting hole, the insertion rod can be inserted into the limiting hole under the drive of the limiting spring, thereby limiting the position of the driving ring, and then limiting the position of the active rod, so that the position of the driving rod is stable, and the insertion rod can be driven to leave the limiting hole by pulling the pull ring, and the operation is simple and convenient.

[0018] The utility model is further configured as follows: a bottom of the insertion rod close to one end of the storage bin is provided with an inclined surface.

[0019] The principle and effect of this technical solution: the setting of the inclined surface enables the insertion rod to enter the limiting hole more conveniently, so that when the user drives the driving ring to press down, the insertion rod can be inserted into the limiting hole more stably.

[0020] The utility model is further configured as follows: it also includes a plurality of reset assemblies arranged at intervals along the circumference of the fixed ring, the reset assemblies include a guide rod, a reset spring and a stopper, the guide rod is fixed to the top of the fixed ring, and the guide rod is slidably inserted with the drive ring, the stopper is fixed to the top of the guide rod, and the reset spring is sleeved on the guide rod and is located between the drive ring and the fixed ring.

[0021] The principle and effect of this technical solution: through the setting of the reset component, after the user pulls the pull ring to separate the insertion rod from the limiting hole, the rebound force of the reset spring can spontaneously drive the driving ring away from the fixed ring, so that the driving ring indirectly drives the driven rod to be stored, thereby making the storage of the driving rod more convenient and eliminating the need for manual adjustment, and the setting of the block prevents the driving ring from detaching from the guide rod.

[0022] The utility model is further configured as follows: a horizontal bubble meter is installed on the top of the storage bin.

[0023] The principle and effect of the technical solution: the setting of the bubble level enables the user to adjust each telescopic rod through the indicators of the bubble level, so that the storage bin can be easily leveled, that is, the device can be easily laid flat.

[0024] The utility model is further configured as follows: the line-releasing and measuring mechanism includes a wheel, a rotating shaft, a locking assembly, a winding roller, a measuring line and a plumb line; the winding roller is rotatably installed in the storage bin; one end of the measuring line is wound around the winding roller; the other end of the measuring line passes through the bottom of the storage bin and the cleaning mechanism and is connected to the plumb line; one end of the rotating shaft is connected to one end of the winding roller; the wheel is installed at the end of the rotating shaft away from the winding roller; and the locking assembly is installed on the rotating shaft.

[0025] The principle and effect of this technical solution is as follows: the rotating shaft is driven to rotate by the turntable, so that the rotating shaft drives the winding roller to rotate, so that the winding roller can play the role of winding and releasing the measuring line, and through the setting of the locking component, the line sinker can be locked by the locking component after reaching the bottom of the pile hole, so that the surveyor can observe and record the length of the measuring line conveniently, and the measuring line passes through the cleaning mechanism, so it can be cleaned by the cleaning mechanism when it is retracted.

The rubber ring is located between the locking nut and the storage bin 101, and the locking nut and the rubber ring are both commonly used parts and there is no need to elaborate on them.

[0035] The cleaning mechanism 301 graphite box, cleaning brush and block 603 (which is consistent with the cleaning mechanism 301 recorded in the comparative patent with announcement number CN218522657U, which is the prior art, so only a brief description is made here), the block 603 is located at the bottom of the graphite box, the cleaning brush is installed at the bottom of the block 603, and the measuring line 205 passes through the top of the graphite box, the block 603 and the cleaning brush.

[0036] The supporting mechanism includes a driving ring 401, a fixing ring 402 and three groups of driving rods arranged at intervals along the circumference of the storage bin 101. The driving ring 401 is slidably mounted outside the storage bin 101, and the fixing ring 402 is fixed outside the storage bin 101 and is located below the driving ring 401. The fixing ring 402 has a stepped shape. The driving rod includes an active rod 403, a driven rod 404, a limit plate 405 and a telescopic rod 406. The top of the active rod 403 is aligned with the driving rod 403. The bottom of the moving ring 401 is hinged, one end of the driven rod 404 is hinged on the side wall of the fixed ring 402, the bottom of the active rod 403 is hinged to the rod body of the driven rod 404, the limiting plate 405 is L-shaped, and one end is fixed to the bottom of the end of the driven rod 404 away from the storage bin 101, the telescopic rod 406 is hinged to the side wall of the limiting plate 405 close to the storage bin 101, and the telescopic rod 406 is abutted against the end of the limiting plate 405 away from the driven rod 404;

[0037] When the telescopic rod 406 plays a supporting role, the telescopic rod 406 abuts against the side wall of the limiting plate 405, and the angle between the telescopic rod 406 and the driven rod 404 is an obtuse angle. A moving wheel 407 is installed at the bottom of the telescopic rod 406, and a horizontal bubble meter 103 is installed on the top of the storage bin 101.

[0038] The limiting mechanism includes two symmetrically arranged limiting units, which include a limiting cylinder 501, an insertion rod 502, a limiting spring 503, a slider 504 and a pull ring 505. The limiting cylinder 501 is fixed on the driving ring 401 and slidably abuts against the storage bin 101. One end of the insertion rod 502 is slidably inserted into the limiting cylinder 501. The slider 504 is slidably arranged in the limiting cylinder 501 and fixed on the insertion rod 502. The pull ring 505 is fixed to the end of the insertion rod 502 away from the storage bin 101. The limiting spring 503 is installed in the limiting cylinder 501 and is located on the side of the slider 504 away from the storage bin 101. A limiting hole 102 matching the insertion rod 502 is opened on the outer wall of the storage bin 101, and an inclined surface is formed on the bottom of the insertion rod 502 close to the storage bin 101.

[0039] There are four groups of reset components arranged at intervals along the circumference of the fixed ring 402. The reset components include a guide rod 601, a reset spring 602 and a stopper 603. The guide rod 601 is fixed to the top of the fixed ring 402, and the upper end of the guide rod 601 is slidably inserted into the drive ring 401. The stopper 603 is fixed to the top of the guide rod 601. The reset spring 602 is sleeved on the guide rod 601 and is located between the drive ring 401 and the fixed ring 402.

[0040] The specific implementation process is as follows:

[0041] When the device is in use, the driving plate can be pressed down to drive the driving rod to move, so that the insertion rod 502 corresponds to the limiting hole 102, and the insertion rod 502 enters the limiting hole 102 under the drive of the limiting spring 503 to play a limiting role. At this time, the axial direction of the driven rod 404 is consistent with the horizontal direction, and the telescopic rod 406 is moved to drive the moving wheel 407 to rotate on the ground, so that the angle between the telescopic rod 406 and the driven rod 404 is rotated to become an obtuse angle, and abuts against the limiting plate 405. At this time, the device can be placed on the ground, and driven by its own gravity, the telescopic rod 406 is pressed tightly against the limiting plate 405, thereby making the driving rod unable to move, providing stable support and fixing for the storage bin 101, and by adjusting the length of each telescopic rod 406, the device can be leveled by observing the level bubble meter 103, and then the line-laying measuring mechanism can be controlled to enter the pile hole, and when the plumb line 206 reaches the bottom of the pile hole, the depth of the pile hole can be recorded by observing the length of the measuring line 205, and then the pull rings 505 on both sides are pulled to make the insertion rod 502 leave the limiting hole 102, that is, the driving plate can automatically drive the driving plate to rise under the drive of the reset spring 602, and then the driving rod can be stored, so that the device is easy to transport and store, saving space.

[0042] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical scheme or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the technical scheme of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
