Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a device for measuring the drilling depth of bored piles. Background Technology

[0002] Drilled piles are piles made by forming pile holes in the foundation soil on the engineering site through mechanical drilling, steel pipe soil displacement, or manual excavation, and then placing a steel cage inside and pouring concrete.

[0003] After the construction workers complete the drilling of the bored pile, it is necessary to measure and verify the hole depth. Existing measuring devices are generally set up above the hole, but this method has poor stability. Especially for holes of different sizes, the frame is quite inconvenient to use, and mud and dirt easily adhere to the measuring rope after it is raised. If it is not cleaned in time, it will affect the subsequent use. Therefore, we propose a device for measuring the hole depth of bored piles. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A device for measuring the drilling depth of a bored pile includes: a fixed frame and a measuring component disposed on the fixed frame; the fixed frame includes a horizontal frame and a vertical frame installed on the side of the horizontal frame; the measuring component includes a positioning mechanism installed on the horizontal frame, a measuring mechanism assembled on the vertical frame, and a cleaning mechanism installed on the measuring mechanism; the positioning mechanism includes a positioning ring disposed in the middle of the horizontal frame, a fixing bolt threaded to the middle of the positioning ring, a slot opened on the horizontal frame, a locking block locked in the slot, a fixing plate fixed below the locking block, a support plate installed on the outside of the fixing plate, and a spring telescopic rod hinged and fixed between the fixing plate and the fixing bolt.

[0007] In a preferred embodiment, the present invention can be further configured such that the measuring mechanism includes a mounting frame mounted on the top of the vertical frame, a fixed box fixed in the middle of the mounting frame, a take-up roller mounted in the middle of the fixed box, a motor connected to the end of the take-up roller, a measuring rope wound on the take-up roller, and a counterweight fixed to the end of the measuring rope.

[0008] In a preferred embodiment, the present invention can be further configured such that: the cleaning mechanism includes a cleaning frame installed at the bottom of the measuring mechanism, a compression spring fixed at the bottom of the cleaning frame, a compression roller connected to the end of the compression spring, a nozzle disposed above the compression roller, a water pipe connected to the nozzle, and a pipe connector connected to the end of the water pipe.

[0012] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model uses a measuring component to place a fixing plate into a hole, and then the fixing bolt is screwed down. The fixing plate is adaptively supported by a spring telescopic rod. During the process, the spring inside the spring telescopic rod is continuously compressed until the spring telescopic rod reaches a horizontal position or the support for the fixing plate reaches a preset range.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a device for measuring the hole depth of bored piles.

[0025] Combination Figures 1-2 As shown, the present invention provides a borehole depth measuring device for bored piles, comprising: a fixed frame 100 and a measuring component 200 disposed on the fixed frame 100, wherein the fixed frame 100 includes a horizontal frame 110 and a vertical frame 120 installed on the side of the horizontal frame 110.

[0026] The measuring assembly 200 includes a positioning mechanism mounted on the crossbeam 110, a measuring mechanism mounted on the vertical frame 120, and a cleaning mechanism mounted on the measuring mechanism. The positioning mechanism includes a positioning ring 210 located in the middle of the crossbeam 110, a fixing bolt 220 threaded to the middle of the positioning ring 210, a slot 230 on the crossbeam 110, a locking block 240 locked within the slot 230, a fixing plate 250 fixed below the locking block 240, and a support plate 260 mounted on the outside of the fixing plate 250. A spring telescopic rod 270 is hinged and fixed between the fixed plate 250 and the fixing bolt 220. This design allows the fixed plate 250 to be placed into the hole, and then the fixing bolt 220 to be screwed downwards. The spring telescopic rod 270 provides adaptive support to the fixed plate 250. During the process, the spring inside the spring telescopic rod 270 is continuously compressed until the spring telescopic rod 270 reaches a horizontal position or the support for the fixed plate 250 reaches a preset range. This design achieves adaptive fixing for holes of different sizes, thereby enhancing the stability of the fixing frame 100 standing on the hole and ensuring stable measurement.

[0027] Specifically, the measuring mechanism includes a mounting frame 310 mounted on the top of the vertical frame 120, a fixed box 320 fixed in the middle of the mounting frame 310, a take-up roller 330 mounted in the middle of the fixed box 320, a motor 340 connected to the end of the take-up roller 330, a measuring rope 350 wound on the take-up roller 330, and a counterweight 360 fixed to the end of the measuring rope 350. By driving the take-up roller 330 to rotate through the motor 340, the measuring rope 350 can move up and down with the counterweight 360. When the counterweight 360 reaches the bottom of the hole, the measuring scale on the measuring rope 350 is observed to determine the hole depth, which is relatively convenient to operate.

[0028] Furthermore, the cleaning mechanism includes a cleaning frame 410 installed at the bottom of the measuring mechanism, a compression spring 420 fixed at the bottom of the cleaning frame 410, a compression roller 430 connected to the end of the compression spring 420, a nozzle 440 disposed above the compression roller 430, a water pipe 450 connected to the nozzle 440, and a pipe connector 460 connected to the end of the water pipe 450. When the measuring rope 350 is retrieved, the compression spring 420 and the compression roller 430 can adaptively compress the measuring rope 350. At the same time, a water supply pipe can be connected to the pipe connector 460, so that cleaning water is sprayed out from the nozzle 440 along the water pipe 450 to clean the vertical measuring rope 350. The simultaneous cleaning and compression can effectively clean the mud and dirt on the measuring rope 350, making it highly practical.

[0029] It should be noted that the fixing bolt 220 has a through hole 221 in the middle, which facilitates the passage of the measuring rope 350 and also guides the measuring rope 350. The design is reasonable.

[0030] Furthermore, the fixing plate 250 has an arc-shaped plate structure, which can achieve a better positioning effect in the circular forming hole.

[0031] Furthermore, the counterweight 360 adopts a rhomboid counterweight structure, which makes it easier for the counterweight 360 to enter and exit the hole and reduces the obstruction.

[0032] Specifically, this solution also includes a controller, which is a general-purpose industrial controller. Its core hardware structure includes a general-purpose microprocessor (CPU), memory (RAM / ROM), and input / output (I / O) interface modules. This controller connects to conventional electrical equipment such as motors and hydraulic rods involved in the solution through its I / O interfaces and runs preset control programs or algorithms.

[0033] The above controller has the following control methods:

[0034] Program control (automatic mode): The controller runs a preset control program or algorithm, based on sensor input or preset logic, to automatically realize the start-up, stop, state switching, timing control and linkage functions of various electrical equipment.

[0035] Manual Control (Local / Remote Mode): The controller is equipped with a manual control interface (such as physical buttons, a touchscreen, an HMI, or a remote command receiver module). Operators can directly send commands to the controller through this interface to independently (individually) control the start, stop, or status adjustment of any specified electrical device (such as a specific motor or hydraulic rod). This mode is typically used for commissioning, maintenance, or specific operational needs. The controller has a mode switching function, allowing for safe switching between automatic program control and manual control.

[0036] The control program, manual operation logic, and mode switching mechanism are all implemented based on specific application requirements. The specific model of the processor, storage capacity, I / O interface protocol, and the specific form of the manual control interface can be determined by those skilled in the art based on the specifications of the selected general controller, the characteristics of the controlled device, and conventional human-machine interaction requirements. These are common implementation methods in the prior art and can be understood by those skilled in the art, so there is no need to elaborate on the specific details.

[0037] The working principle and usage process of this utility model are as follows: First, place the horizontal frame 110 and the vertical frame 120 above the hole to be measured, so that the fixing plate 250 is located inside the hole. Then, screw the fixing bolt 220 downwards, and use the spring telescopic rod 270 to adaptively support the fixing plate 250. During the process, the spring inside the spring telescopic rod 270 is continuously compressed until the spring telescopic rod 270 reaches a horizontal position or the support for the fixing plate 250 reaches a preset range, thus completing the fixing. During measurement, the motor 340 drives the winding roller. Rotate 330 to move the measuring rope 350 downwards with the counterweight 360 until the counterweight 360 touches the bottom. Observe the scale on the measuring rope 350 to determine the hole depth and complete the measurement. Then drive the measuring rope 350 to retract. Use the compression spring 420 and compression roller 430 to adaptively compress the measuring rope 350. At the same time, a water supply pipe can be connected to the pipe joint 460 so that cleaning water is sprayed out from the nozzle 440 along the water pipe 450 to clean the vertical measuring rope 350. Cleaning and compression can be carried out simultaneously.

[0038] The terms "fixed," "installed," "connected," "set up," "open," "equipped with," "embedded," and "assembled" used in this manual to describe the position or relationship of components all refer to conventional physical connections or spatial configurations that can be understood and implemented by those skilled in the art based on the function of the relevant components, the context, and common knowledge. These relationships encompass, but are not limited to, specific forms such as welding, bonding, threaded fastening, snap-fit, interference fit, plug-in, sliding fit, hinge, integral molding, adjacent arrangement, and opening or slot accommodating. Their purpose is to clearly describe the relative positions, mating methods, and functional implementation paths between components, rather than limiting a single specific structural detail. To ensure a smooth and concise reading experience and ease of understanding, no separate explanation is provided after each term.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
