Description

Technical Field

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

[0002] Bored cast-in-place piles refer to piles made by forming pile holes in the foundation soil through mechanical drilling or manual excavation at the construction site, placing a steel cage inside and pouring concrete. Before placing the steel cage and pouring concrete, it is necessary to measure the depth of the pile hole in combination with the survey report to determine whether the excavation has reached the target bearing layer.

[0003] A Chinese patent with announcement number CN218120858U discloses a device for measuring the hole depth of bored piles. The device includes a frame, a rotating shaft, a roller, a measuring rope and a measuring hammer. The lower end of the measuring rope is connected to the measuring hammer, and the top end of the measuring rope is connected to the roller. The measuring rope is wound around the roller as the roller rotates. The above scheme utilizes the rotating roller to drive the measuring rope with a scale to rise or fall in the hole, thereby achieving the purpose of measuring the hole depth.

[0004] During the actual construction process, the diameters of the pile holes are different. When using the above solution, the two supporting parts of the frame need to be placed on both sides of the pile hole respectively. In order to measure pile holes of various diameters, a wider frame is required to adapt to the large-diameter pile holes. However, the width of the frame cannot be adjusted, which makes it inconvenient to store. Utility Model Content

[0005] The utility model aims to provide a pile hole depth detection device to solve the problem of inconvenience in storage in the above-mentioned solution.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pile hole depth detection device comprises a fixed plate, a movable plate and a graduated rope, wherein a slide groove is recessed along the horizontal direction on the left side wall of the fixed plate, a through hole is vertically arranged along the left side of the top of the fixed plate, a support plate is fixedly arranged on the right side of the top of the fixed plate, a winding roller is rotatably arranged on the upper side of the support plate in the front-rear direction, the right end of the movable plate is slidably inserted in the slide groove, a first through groove cooperating with the through hole is arranged on the top of the movable plate, one end of the graduated rope is wound around the winding roller and fixedly connected to the side wall of the winding roller, the other end of the graduated rope passes through the through hole and the first through groove, and is fixedly connected to a measuring hammer.

[0008] The principle and effect of this technical solution:

[0009] When measuring, slide the movable plate away from the slide until the movable plate and the fixed plate can be placed on both sides of the top of the pile hole respectively, rotate the winding roller to collect the scale rope until the top of the measuring hammer abuts against the bottom of the fixed plate, slowly rotate the winding roller in the opposite direction to open the scale rope, and the measuring hammer will drop accordingly. When the measuring hammer touches the bottom wall of the pile hole, calculate the sum of the scale change of the scale rope and the height of the measuring hammer, which is the depth of the pile hole.

[0010] Through the above arrangement, by sliding the movable plate into the slide groove, the floor space occupied by the utility model in an idle state can be reduced, which is convenient for storage. At the same time, the depth of pile holes of various hole diameters can be measured, which broadens the application scenarios of the utility model.

[0011] In the utility model, the side wall of the slide groove is provided with a second through groove, the side wall of the movable plate is fixedly provided with a protrusion matched with the second through groove, the protrusion is slidably embedded in the second through groove, and when the protrusion abuts against the left end of the second through groove, there is a gap between the scale rope and the right end of the first through groove. Through the above arrangement, it is possible to avoid the movable plate from being separated from the slide groove in the process of sliding the movable plate in the direction away from the slide groove, and at the same time, it is possible to avoid errors in the measurement results caused by the scale rope being stretched by the side wall of the first through groove, thereby improving the practicality of the utility model.

[0012] In the utility model, a mounting frame is fixedly arranged on the top of the fixed plate between the through hole and the winding roller, a dynamometer is hung on the top of the mounting frame, a first pulley is hung below the dynamometer, and a scale rope is wound around the first pulley.

[0013] The principle and effect of this technical solution:

[0014] In the process of lowering the measuring hammer under the stretched scale rope, the reading of the dynamometer gradually increases due to the gravity of the measuring hammer and the scale rope. When the measuring hammer touches the bottom wall of the pile hole, the reading of the dynamometer decreases significantly, and the change value of the scale rope can be measured.

[0015] Through the above arrangement, the descending distance of the measuring hammer can be accurately measured, thereby improving the accuracy of the measurement result of the utility model.

[0016] In the utility model, a second pulley is rotatably arranged on the top of the fixed plate between the through hole and the mounting frame, and a perforated plate is fixedly arranged between the mounting frame and the winding roller, the scale rope is wound around the second pulley and passes through the perforated plate, and the through hole, the first pulley, the second pulley and the perforated plate are in the same vertical plane. Through the above arrangement, the shaking amplitude of the measuring hammer in the process of opening the scale rope can be reduced, and the accuracy of the measurement result of the utility model can be further improved.

[0017] In the utility model, the left side wall of the fixed plate is fixedly provided with a buckle outside the slide groove, the left side wall of the movable plate is fixedly provided with a mounting plate, the right side wall of the mounting plate is concavely provided with a groove that cooperates with the buckle, the side wall of the groove is provided with a limiting groove, a limiting block is slidably arranged in the limiting groove, a guide push inclined surface that cooperates with the buckle is provided on the side of the limiting block close to the buckle, a compression spring is provided between the limiting block and the end wall of the limiting groove, the side wall of the limiting groove is provided with a third through groove that passes through the side wall of the mounting plate, and the side wall of the limiting block is fixedly provided with a lever that passes through the third through groove.

[0018] The principle and effect of this technical solution:

[0019] After the measurement is completed, the fixed plate and the mounting plate are abutted against each other. At this time, the buckle is inserted into the groove, and the limit block is pushed open by the guide inclined surface. Then the limit block performs a reset movement under the action of the compression spring and jams the buckle. Before measuring again, move the lever to slide the limit block so that the limit block is completely located in the limit groove, and slide the movable plate.

[0020] Through the above arrangement, the integrity of the utility model in an idle state can be improved, making storage and transportation convenient.

[0021] In the utility model, the left side of the top of the mounting plate and the right side of the top of the fixed plate are respectively penetrated with an insertion rod along the vertical sliding direction. Through the above arrangement, after the movable plate and the fixed plate are respectively placed on both sides of the top of the pile hole, the movable plate and the fixed plate can be fixed to the ground to avoid displacement and flipping of the movable plate and the fixed plate during the measurement process, thereby improving the safety of the utility model and ensuring the accuracy of the measurement results.

[0022] In the utility model, the side wall of the support plate is threaded with a fastening bolt, and one end of the fastening bolt can abut against the side wall of the winding roller. Through the above arrangement, the winding roller can be prevented from rotating when the utility model is in a restricted state, thereby improving the practicality of the utility model.
