Description

Technical Field

[0001] This utility model relates to the field of pile foundation cross-section detection technology, specifically a pile foundation cross-section detection device. Background Technology

[0002] In modern construction engineering, pile foundations, as the foundation of a building, directly affect the stability and safety of the entire building structure. With the acceleration of urbanization, high-rise buildings, large bridges, water conservancy facilities, and various complex infrastructure projects are constantly emerging, placing higher demands on the quality of pile foundations.

[0003] Existing technology uses mechanical cutting methods to extract cylindrical core samples from the pile concrete, and obtains quality information about the pile concrete through direct observation, measurement, and testing of the core samples.

[0004] When the drill rod is pulled out of the pile, a large amount of soil, along with broken concrete, climbs and accumulates along the drill rod's threads and outer wall, greatly hindering the drill rod's reuse. Cleaning these stubborn residues requires repeated rinsing and scrubbing with tools such as high-pressure water guns and wire brushes, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a pile foundation cross-section detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pile foundation cross-section detection device, comprising:

[0007] An operating platform, the bottom of which is fixedly connected to a support;

[0008] A transmission assembly is located at the bottom of the operating platform. The transmission assembly includes a transmission frame and a motor fixedly connected to the bottom of the operating platform. A threaded rod is fixedly connected to the output end of the motor. A threaded block is threadedly connected to the threaded rod. A sliding block is fixedly connected to the threaded block. A fixed frame is slidably connected to the sliding block. A fixed ring is slidably connected to the bottom of the transmission frame. A fixed rod is fixedly connected to the fixed ring. An opening is provided at the bottom of the threaded rod.

[0009] Furthermore, a mechanical telescopic rod is fixedly connected between the motor and the threaded rod. A threaded groove is provided on the opening at the bottom of the threaded rod, and a sliding port is provided on the sliding block. The sliding block is slidably connected to the fixed rod through the sliding port.

[0010] The above technical solution is adopted: by opening a sliding port on the sliding block, it is convenient to use the fixed rod fixedly connected to the bottom of the operating platform for limiting.

[0011] Furthermore, a torsion spring is fixedly connected between the sliding block and the fixed frame.

[0012] The above technical solution is adopted: by setting a torsion spring, when the threaded rod is drilled downwards, the fixing frame folds to avoid increasing the resistance after the threaded rod rotates downwards.

[0013] Furthermore, a drill bit is fixedly connected to the bottom of the threaded rod, and an opening is formed on the drill bit at the bottom of the threaded rod, with the drill bit at the bottom of the threaded rod being fixedly connected to the threaded rod.

[0014] The above technical solution involves fixing a drill bit to the bottom of the threaded rod, which facilitates better insertion of the threaded rod into the ground during use.

[0015] Furthermore, a fixing layer is fixedly connected to the threaded rod.

[0016] The above technical solution involves fixing a fixed layer to the threaded rod to limit the position of the threaded block.

[0017] Furthermore, the threaded block is slidably connected to the fixed layer.

[0018] Using the above technical solution: when the threaded rod is drilled downwards, the threaded block will be held in place by the fixing layer and will not move upwards.

[0019] Furthermore, the bracket is equipped with casters at its bottom.

[0020] The above technical solution involves installing casters at the bottom of the bracket to facilitate its movement.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a motor at the bottom of the device serves as the power source. The motor output is fixedly connected to the threaded rod. When sampling is complete and the threaded rod needs to be pulled out, the motor is started to rotate its output in the opposite direction. The motor drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the transmission frame, it moves upward under the action of the threaded transmission. At the same time, the fixed frame and the sliding block are connected by a torsion spring, and the sliding block and the fixed rod are slidably connected through a sliding port. This structure allows the fixed frame to unfold under the restoring force of the torsion spring and the limiting guidance of the fixed rod when the threaded rod rises, and then rotate into the surrounding sample layer. When the fixed frame is in the limiting state against the fixed rod, the threaded block cannot rotate. As the threaded rod rises, the fixed frame effectively scrapes off the soil trapped on the threaded rod, avoiding the accumulation of soil on the drill rod threads and outer wall, and eliminating the tedious process of repeated cleaning with high-pressure water guns, wire brushes, and other tools.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a pile foundation cross-section detection device, comprising:

[0034] Operating platform 1, with a bracket 11 fixedly connected to its bottom;

[0035] The transmission assembly 2 is located at the bottom of the operating platform 1. The transmission assembly 2 includes a transmission frame 21 fixedly connected to the bottom of the operating platform 1 and a motor 22. The output end of the motor 22 is fixedly connected to a threaded rod 29. A threaded block 23 is threadedly connected to the threaded rod 29. A sliding block 28 is fixedly connected to the threaded block 23. A fixed frame 26 is slidably connected to the sliding block 28. A fixed ring 210 is slidably connected to the bottom of the transmission frame 21. A fixed rod 25 is fixedly connected to the fixed ring 210. An opening is provided at the bottom of the threaded rod 29.

[0036] A mechanical telescopic rod is fixedly connected between the motor 22 and the threaded rod 29. A threaded groove is provided on the opening at the bottom of the threaded rod 29. A sliding port is provided on the sliding block 28. The sliding block 28 is slidably connected to the fixed rod 25 through the sliding port. By providing a sliding port on the sliding block 28, it is convenient to use the fixed rod 25 fixedly connected to the bottom of the operating platform 1 for limiting.

[0037] In this utility model, when in use, first move the device to a suitable position and fix the caster wheel. Then, start the motor 22 to make the threaded rod 29 rotate. Since the threaded rod 29 is threadedly connected to the transmission frame 21, when the threaded rod 29 rotates, it will be driven to rotate downwards, and the sample will be gradually collected through the opening in the threaded rod 29.

[0038] When the threaded rod 29 is inserted into the sample to a certain depth and needs to be extracted, the motor 22 is started to rotate its output end in the opposite direction, causing the threaded rod 29 to gradually move upward. At this time, the fixing frame 26 will be unfolded. Since the fixing frame 26 is set as a hollow structure, the fixing frame 26 will be inserted into the surrounding sample layer. At this time, under the limiting action of the fixing frame 26, the fixing frame 26 gradually abuts against the fixing rod 25, so that the threaded block 23 will not rotate. During the process of the threaded rod 29 rising, the soil on the threaded rod 29 will be scraped off.

[0039] Then, when the sliding block 28 abuts against the drill bit at the bottom of the threaded rod 29, the motor 22 is started to rotate in the opposite direction, causing the fixed frame 26 to be pulled out from the surrounding sample layer. The hydraulic telescopic rod on the bracket 11 is then activated to pull out the fixed frame 26, thus completing the sampling.

[0040] The motor 22 at the bottom of the device serves as the power source. The output end of the motor 22 is fixedly connected to the threaded rod 29. When sampling is completed and the threaded rod 29 needs to be pulled out, the motor 22 is started to rotate its output end in reverse. The motor 22 drives the threaded rod 29 to rotate. Since the threaded rod 29 is threadedly connected to the transmission frame 21, the threaded rod 29 will move upward under the action of threaded transmission. Meanwhile, the fixed frame 26 and the sliding block 28 are connected by a torsion spring 27, and the sliding block 28 and the fixed rod 25 are slidably connected through a sliding port. This structure allows the fixed frame 26 to unfold under the elastic recovery effect of the torsion spring 27 and the limiting guidance of the fixed rod 25 when the threaded rod 29 rises, and to rotate into the surrounding sample layer. When the fixed frame 26 is in the limiting state against the fixed rod 25, the threaded block 23 cannot rotate. As the threaded rod 29 rises, the fixed frame 26 effectively scrapes off the soil wrapped on the threaded rod 29, avoiding the accumulation of soil on the drill rod threads and outer wall, saving the tedious process of repeated cleaning by manual high-pressure water guns, wire brushes and other tools.

[0041] Furthermore, such as Figures 1 to 5As shown, a torsion spring 27 is fixedly connected between the sliding block 28 and the fixed frame 26. By setting the torsion spring 27, when the threaded rod 29 is drilled downwards, the fixed frame 26 is folded to avoid increasing the resistance after the threaded rod 29 is turned downwards.

[0042] A drill bit is fixedly connected to the bottom of the threaded rod 29. An opening is made in the drill bit at the bottom of the threaded rod 29. The drill bit at the bottom of the threaded rod 29 is fixedly connected to the threaded rod 29. By fixing the drill bit to the bottom of the threaded rod 29, it is convenient for the threaded rod 29 to be turned into the ground more easily during use.

[0043] A fixing layer 24 is fixedly connected to the threaded rod 29, and the position of the threaded block 23 is limited by the fixing layer 24 fixedly connected to the threaded rod 29.

[0044] The threaded block 23 is slidably connected to the fixed layer 24. When the threaded rod 29 drills downward, the threaded block 23 will be blocked by the fixed layer 24 and will not move upward.

[0045] The bracket 11 is equipped with casters at the bottom, which facilitates the movement of the bracket 11.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
