Description

Technical Field

[0001] The utility model belongs to the technical field of foundation construction detection, and specifically relates to a foundation construction pile hole depth supervision and 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. After the construction party builds the pile holes, the supervision party needs to test the depth of the pile holes to ensure that the depth of the pile holes meets the set requirements. After the test is qualified, the steel cage can be lowered, concrete can be poured, etc.

[0003] A Chinese patent with announcement number CN215907837U discloses a device for measuring the hole depth of bored piles. In this solution, a measuring rope is wound on a reel, and the reel is rotatably connected between support platforms on both sides. The measuring rope is passed through a through hole at the bottom of the support platform and the reel is controlled to rotate to release the line until the rope hammer reaches the bottom of the pile foundation hole, and then the length of the measuring rope is marked and measured.

[0004] However, in actual use, when testing the depth of the bored pile hole, the mud attached to the measuring rope will reel in with the measuring rope. After the mud dries, the surface of the measuring rope will become hard, which will affect the operation of retracting and releasing the rope in subsequent use, and cause the measuring rope to be unable to be in a vertical straight line, thus affecting the accuracy of the measurement. Utility Model Content

[0005] The utility model aims to provide a foundation construction pile hole depth monitoring and detection device to solve the problem that the prior art mentioned above cannot clean the pull rope.

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

[0007] A mounting plate, on which a wire-laying measuring mechanism is arranged;

[0008] The cleaning mechanism includes a U-shaped bracket, a driving rod and two L-shaped connecting rods. The U-shaped bracket is arranged on the front side of the mounting plate. The two connecting rods are symmetrical about the U-shaped bracket, and the middle part of the connecting rod is hinged to the side wall of the U-shaped bracket. The driving rod includes an active rod, a knob and a spring. One end of the active rod is hinged to the upper ends of the two connecting rods. The knob abuts against the U-shaped bracket and a threaded hole is arranged at the bottom. The other end of the active rod passes through the U-shaped bracket and is threadedly inserted into the threaded hole. A rotating ring is arranged on the side wall of the knob. The spring is sleeved on the active rod. The lower end of the active rod is connected to the chassis, and the spring is located between the U-shaped bracket and the chassis. The lower ends of the two connecting rods are respectively connected to semicircular cleaning plates.

[0009] The principle and effect of this technical solution:

[0010] 1. The depth of the pile hole is measured by the laying-out measurement mechanism set on the mounting plate, and the mud stained during the laying-out measurement process is cleaned by the cleaning mechanism to keep the laying-out measurement mechanism clean and tidy, and to avoid the mud drying and affecting the laying-out measurement work.

[0011] 2. Since the bottom of the active rod cannot rotate relative to the U-shaped bracket due to the hinge connection with the connecting rod, and its position is limited by the connecting rod, the height of the bottom of the active rod can be controlled by controlling the matching length between the active rod and the threaded hole, thereby controlling the angle between the two connecting rods, so that the two connecting rods can clamp or release the measuring rope, so that the mud on the measuring rope can be cleaned when the line is reeled in, ensuring the cleanliness and repeated use of the defense line measurement mechanism.

[0012] 3. The spring is set so that the active rod and the knob always have a tendency to move downward spontaneously, that is, when the spring force is not overcome, the knob always abuts against the U-shaped bracket and can only move upward relative to the U-shaped bracket, that is, when the matching length of the active rod and the threaded hole is certain, the active rod can only drive the top of the connecting rod to move upward, so that the cleaning plates at the bottom of the connecting rod can only approach each other, and the active rod cannot be driven downward by the knob to make the cleaning plates move away from each other. Therefore, when the device is reeling in, when the knob is adjusted into place, the distance between the two cleaning plates cannot be expanded, so that the clamping force of the cleaning plate on the measuring rope can remain stable, so that when the measuring rope is reeling in, the external mud can be cleaned by the cleaning plate, and the clamping force is stable and adjustable, so that the measuring rope will not be damaged.

[0013] 4. When releasing the line, the spring rebound force makes it difficult for the knob to move upward, and the cleaning plate is not easy to produce a large clamping force on the measuring rope, thereby avoiding the influence of the cleaning plate on the measuring rope, and at the same time playing the role of line management and cleaning.

[0014] The utility model is further configured as follows: the line-releasing and measuring mechanism includes a rotating handle, a rotating shaft, a winding roller, a measuring rope, a plumb line and two support plates, the two support plates are mounted on the mounting plate, the winding roller is rotatably mounted between the two support plates through the rotating shaft, one end of the measuring rope is wound around the winding roller, the other end of the measuring rope passes through the inner side of the cleaning plate and is connected to the plumb line, and the rotating handle is mounted on the end of the rotating shaft away from the winding roller.

[0015] The principle and effect of this technical solution is as follows: the rotating handle drives the rotating shaft to rotate, which in turn drives the winding roller to rotate, so that the winding roller can wind up and release the measuring rope, and by controlling the knob, the plumb line can be clamped and locked by the cleaning plate after reaching the bottom of the pile hole, so that the measuring rope can be kept straight, making it easier for the surveyor to observe and record the length of the measuring rope.

[0016] The utility model is further configured as follows: an arc-shaped cleaning pad is attached to the inner side of the cleaning plate, the cleaning pad has an arc-shaped groove penetrating vertically, and the measuring rope is located between two arc-shaped grooves.

[0017] The principle and effect of this technical solution: the arc grooves on the two cleaning pads cooperate with each other to wrap the measuring rope. When controlling the angle between the two connecting rods, the clamping force of the two cleaning pads can be controlled, thereby cleaning the mud on the measuring rope, thereby preventing the measuring rope from being fixed after drying, resulting in the measuring rope being unable to be fully stretched vertically into a straight line during subsequent use, resulting in inaccurate measurement accuracy.

[0018] The utility model is further configured as follows: a first connecting rod is arranged on the side wall of the supporting plate, a roller is rotatably mounted on the side wall of the first connecting rod, and the measuring rope is in contact with the roller.

[0019] The principle and effect of this technical solution: the first connecting rod extends the drum out of the mounting plate for a certain distance. When measuring, the measuring rope can be passed around the drum, so as to facilitate extending the measuring rope to the range of the pile hole. The drum is used to change the direction of the measuring rope so that the measuring rope can be vertically extended to the bottom of the pile hole, and the measuring rope can be directed to its cleaning mechanism, so as to better pass through the cleaning mechanism.

[0020] The utility model is further configured as follows: one end of the first connecting rod close to the supporting plate is rotatably mounted on the side wall of the supporting plate.

[0021] The principle and effect of this technical solution: the first connecting rod is rotatably installed on the side wall of the support plate, so that the roller and the connecting rod can be rotated upward around the rotation point, so as to store the roller, thereby facilitating storage and reducing occupied space, and locking is performed by controlling the rotation angle.

[0022] The utility model is further configured as follows: a second connecting rod is installed on the side wall of the U-shaped bracket, and one end of the second connecting rod close to the mounting plate is rotatably mounted on the side wall of the mounting plate.

[0023] The principle and effect of the technical solution: the second connecting rod and the mounting plate are rotatably installed, and the second connecting rod can be rotated to a vertical position, thereby facilitating the storage of the cleaning mechanism and reducing the occupied space of the device.

[0024] The utility model is further configured as follows: the upper ends of the two connecting rods are rotatably connected with a U-shaped connecting piece, and the upper end of the U-shaped connecting piece is hinged to the bottom of the chassis.

[0025] The principle and effect of this technical solution: the upper ends of the two connecting rods are hinged by a U-shaped connecting piece, so that the active rod can be hinged using the U-shaped piece, thereby improving the stability of the measuring rope when it is reeled in, and the flexibility of the connection between the two connecting rods and the active rod.
