Description

Technical Field

[0001] This utility model relates to the field of cast-in-place pile measurement technology, specifically a device for measuring the height of the top of a bored cast-in-place pile. Background Technology

[0002] Cast-in-place piles are piles formed on-site by creating pile holes in the foundation through mechanical drilling, manual excavation, and soil displacement with steel pipes, then placing a steel cage inside and finally pouring concrete to form the pile body.

[0003] Chinese Patent Publication No. CN200986440Y discloses "A Device for Measuring the Height of Concrete Cast-in-Place Piles," comprising a detection probe, an electric cable winch, and a parameter detection and recording box. This invention effectively solves the problems of low efficiency and difficulty in accurately calculating the height of cast-in-place piles by comprehensively utilizing the detection probe, electric cable winch, and parameter detection and recording box.

[0004] While existing technologies can perform measurements, the use of conical drill bits for deep drilling leads to poor chip removal, affecting drilling quality and potentially causing the drill bit to overheat. Furthermore, the tip of the conical drill bit is relatively fragile and easily damaged when encountering hard materials or due to improper use. Additionally, during use, the signal cable may become disordered, locally squeezed and deformed, or even cross-entangled, causing the signal cable to lock up. As the signal cable repeatedly moves up and down in the hole, mud accumulates on the surface of the signal cable, forming a mud shell layer that affects signal transmission. Utility Model Content

[0005] The purpose of this utility model is to provide a device for measuring the height of the top of a bored cast-in-place pile, in order to solve the problems in the background art where, during use, the use of a conical drill bit for drilling leads to poor chip removal, affecting drilling quality and potentially causing the drill bit to overheat. Furthermore, the tip of the conical drill bit is relatively fragile and easily damaged when encountering hard materials or improper use. At the same time, during use, the signal cable is disordered, locally squeezed and deformed, or even cross-entangled, causing the signal cable to lock up. When the signal cable repeatedly rises and falls in the hole, mud accumulates on the surface of the signal cable, forming a mud shell layer, which affects signal transmission.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a device for measuring the height of the top of a bored cast-in-place pile, comprising a base plate, a drilling depth assembly provided on one side of the base plate, and a take-up assembly provided on the top of the base plate;

[0007] The drilling depth assembly includes a detection probe, and a spiral drill bit is rotatably embedded inside the detection probe. A connecting post is rotatably embedded inside the detection probe, and a connecting gear is fixedly connected to the outer surface of the connecting post. A first helical gear is fixedly connected to the outer surface of the connecting post. A second helical gear is rotatably embedded inside the detection probe, and the outer surface of the second helical gear meshes with the first helical gear. One side of the outer surface of the second helical gear is fixedly connected to the spiral drill bit.

[0008] The take-up assembly includes multiple first support plates, and each of the multiple first support plates has a take-up reel rotatably embedded inside. The top of the outer surface of the base plate is fixedly connected to a second support plate, and each of the multiple second support plates has a reciprocating threaded rod rotatably embedded inside. The outer surface of the reciprocating threaded rod is threaded with a threaded block, and the outer surface of the threaded block is fixedly connected to multiple thread-connecting posts.

[0009] Preferably, the detection probe has a power column embedded inside for rotation, and a power gear is fixedly connected to the outer surface of the power column.

[0010] Preferably, the detection probe has a transmission column embedded inside for rotation, and a transmission gear is fixedly connected to the outer surface of the transmission column. The outer surface of the transmission gear meshes with the connecting gear and the outer surface of the transmission gear meshes with the power gear.

[0011] Preferably, a limiting groove is fixedly connected to one side of the outer surface of the plurality of second support plates, a limiting rod is fixedly connected to the outer surface of the threaded block, and a roller is rotatably sleeved on the outer surface of the limiting rod, the roller being slidably embedded inside the limiting groove.

[0012] Preferably, the detection probe has a motor housing inside, and the motor housing has an internal motor inside, the output shaft of which is fixedly connected to the power column.

[0013] Preferably, a first motor plate is fixedly connected to one side of the outer surface of one of the plurality of first support plates, and a first motor is provided on the top of the outer surface of the first motor plate. The output shaft of the first motor is fixedly connected to the take-up reel. A second motor plate is fixedly connected to one side of the outer surface of one of the plurality of second support plates, and a second motor is provided on the top of the outer surface of the second motor plate. The output shaft of the second motor is fixedly connected to the reciprocating threaded rod.

[0014] Preferably, the detection probe has a signal line inside, and the side of the signal line away from the detection probe is wound around the outer surface of the take-up reel.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model utilizes an internal motor within the detection probe. This internal motor drives a power column to rotate, which in turn drives a power gear. The power gear drives a geared transmission gear, which in turn drives a geared connecting gear. The connecting gear, through a connecting column, drives a first helical gear. The rotation of the first helical gear drives a geared second helical gear, which in turn drives the auger drill bit. This rotation of the auger drill bit allows for deeper penetration into the grout pile. Through this technical solution, the auger drill bit has helical blades. During rotation, these blades effectively transport and discharge debris upwards along the helical line, thereby reducing debris accumulation in the hole and maintaining the continuity and efficiency of the drilling process.

[0017] Secondly, when the cable needs to be taken in or taken out, the first and second motors are activated, rotating in the same direction and at the same speed. The first motor drives the take-up reel to rotate, and the second motor drives the reciprocating threaded rod to rotate. The reciprocating threaded rod is a type of reciprocating lead screw. The rotation of the reciprocating threaded rod drives the threaded block with the threaded sleeve to move back and forth. Through the reciprocating movement of the threaded block, the signal cable passing through the lead-in post moves back and forth. The lead-in post is made of a soft material, which can wipe away dirt on the signal cable during the take-up process, so that the signal cable is wound back and forth on the take-up reel. Through the above technical solution, the signal cable is wound evenly along the reciprocating trajectory, avoiding the signal cable from crossing and knotting, and the tension is constant throughout the process, avoiding local compression and wear, extending the service life and reducing the failure rate.
