Abstract
Description
Technical Field
[0001] This application relates to the technical field of detection equipment, especially a detector for detecting the thickness of sediment in a pile hole. Background Art
[0002] When drilling cast-in-place piles, the mud in the pile hole sometimes forms a layer of sediment at the bottom of the pile hole, also called sediment. When the sediment accumulates a lot and the thickness of the sediment is relatively thick, the sediment will significantly reduce the bearing capacity of the bottom of the pile hole, thus affecting the quality of the drilled pile. Therefore, the state stipulates that for end-bearing piles, the sediment thickness should not be greater than 50 mm; for friction piles, the sediment thickness should not be greater than 100 mm.
[0003] At present, the hanging hammer method is usually used to measure the thickness of the sediment. The specific operation process is as follows: First, the worker binds the measuring rope with scale lines to the heavy hammer, and then gently puts the heavy hammer into the pile hole until the heavy hammer is placed on the surface of the sediment, and records the reading of the measuring rope at this time. Then the worker gently shakes the measuring rope to make the heavy hammer fall to the bottom of the sediment, and records the reading of the measuring rope again. Finally, subtract the reading of the measuring rope measured for the first time from the reading of the measuring rope measured for the second time, which is the thickness of the sediment.
[0004] Since the pile hole is generally relatively deep, and since the heavy hammer itself has a certain weight, it is time-consuming and laborious to complete the detection by the worker operating the lifting of the heavy hammer, which will affect the detection efficiency. Moreover, due to the large randomness of the worker's hand shaking, it requires a high level of proficiency and experience of the worker. When the shaking is not sufficient and the heavy hammer does not completely fall to the bottom of the sediment, it will inevitably affect the measurement result of the sediment thickness. Utility Model Content
[0005] The purpose of the present utility model is to solve or at least alleviate the problem in the prior art that since the heavy hammer itself has a certain weight, it is time-consuming and laborious to complete the detection by the worker operating the lifting of the heavy hammer, which will affect the detection efficiency.
[0006] To achieve the above purpose, the present utility model provides the following technical solution: A detector for detecting the thickness of sediment in a pile hole, including a detector body, two support frames, and a rotating column rotatably installed between the two support frames. One side outer wall of one of the support frames is fixedly installed with a first support plate, and a first motor for driving the rotating column to rotate is fixedly installed on the first support plate, and the output end of the first motor is fixedly connected to the rotating column. An anti-detaching rope for connecting the detector body is sleeved on the rotating column, and a limiting mechanism for limiting the anti-detaching rope is provided on the rotating column.
[0007] Adopting the above technical solution, when the first motor is started, the output end of the first motor will drive the rotating column to rotate, and the anti-detachment rope will also rotate and move downward accordingly. The downward movement of the anti-detachment rope will drive the detector body to move downward accordingly and move to the bottom of the sediment and abut against it. When the detector body stops moving downward, the anti-detachment rope will bend. Then, the first motor can be started to reverse, so that the detector body can rise. Furthermore, readings can be taken according to the position covered by the mud, and the thickness of the sediment can be obtained. It is simple and convenient, without manual operation, improving work efficiency.
[0008] Optionally, the limiting mechanism includes two limiting discs. Both of the two limiting discs are sleeved on the rotating column. One end of the top of each of the two limiting discs is fixedly installed with a fixing seat. Threaded holes are respectively formed through the two fixing seats, and fixing bolts are screwed in the threaded holes.
[0009] Adopting the above technical solution, by rotating the fixing bolts, the fixing bolts can be driven to move outwards, and thus the connection and fixation of the two fixing seats can be released.
[0010] Optionally, the two limiting discs are circular and are in close fit with the rotating column.
[0011] Adopting the above technical solution, by setting the two limiting discs to be circular and in close fit with the rotating column, it is convenient for installation and limitation.
[0012] Optionally, a fixing frame is fixedly installed on the outer wall of the top of the other support frame. A long box is fixedly installed on one outer wall of the fixing frame.
[0013] Adopting the above technical solution, by setting the fixing frame, the long box can be installed on it.
[0014] Optionally, the long box is located above one side of the rotating column, and a long groove is formed in the outer wall of the bottom of the long box.
[0015] Adopting the above technical solution, by setting the long groove, it can play a role in assisting installation.
[0016] Optionally, a second support plate is fixedly installed on one outer wall of the long box. A second motor is fixedly installed on the outer wall of the top of the second support plate. The output end of the second motor penetrates through one outer wall of the long box and is fixedly installed with a screw rod. The screw rod is a double-threaded screw rod, and abutting plates are symmetrically screwed on the screw rod.
[0017] Adopting the above technical solution, by starting the second motor, the output end of the second motor will drive the screw rod to rotate. The rotation of the screw rod will drive the two abutting plates to move away from each other, and thus the abutting and limiting of the rotating column can be released.
[0018] Optionally, anti-slip pads are provided on the outer walls of the two abutting plates close to each other, and both abutting plates are in contact with the rotating column.
[0019] With the above technical solution, the friction force can be increased by providing anti-slip pads.
[0020] Optionally, the lengths of the two abutting plates are longer than the length of the rotating column.
[0021] With the above technical solution, by setting the lengths of the two abutting plates to be longer than the length of the rotating column, the contact area can be increased, and thus the limiting effect can be strengthened.
[0022] In summary, the beneficial effects of this application are as follows:
[0023] 1. In this new type of application, with the cooperation of components such as the rotating column, by reversing the first motor, the detector body can be lifted, and then the reading can be taken according to the position covered by the mud, and the thickness of the sediment can be obtained. It is simple and convenient, without the need for manual repeated operations, and the work efficiency is improved.
[0024] 2. In this new type of application, with the cooperation of components such as the abutting plates, by starting the second motor, the output end of the second motor will drive the screw rod to rotate. The rotation of the screw rod will drive the two abutting plates to move away from each other, thereby releasing the abutting limit on the rotating column and also preventing the phenomenon of the rotating column from rotating by itself.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] The following is a further detailed description of this application in conjunction with the attached Figures 1-3 drawings.
[0030] Please refer to Figures 1-3, A detector for detecting the thickness of sediment in a pile hole, including a detector body 6, two support frames 1, and a rotating column 2 rotatably installed between the two support frames 1. The detector body 6 is conical and has scale values on its surface. By setting the rotating column 2, it can play a role in assisting installation. On one side outer wall of one of the support frames 1, a first support plate 3 is fixedly installed. On the first support plate 3, a first motor 4 for driving the rotating column 2 to rotate is fixedly installed, and the output end of the first motor 4 is fixedly connected to the rotating column 2. A non-slip rope 5 for connecting the detector body 6 is sleeved on the rotating column 2, and a limiting mechanism for limiting the non-slip rope 5 is provided on the rotating column 2.
[0031] When in use, start the first motor 4. The output end of the first motor 4 will drive the rotating column 2 to rotate and cause the non-slip rope 5 to rotate and move downward. The downward movement of the non-slip rope 5 will drive the detector body 6 to move downward and reach the bottom of the sediment and abut against it. When the detector body 6 stops moving downward, the non-slip rope 5 will bend. Then, the first motor 4 can be started to reverse, so that the detector body 6 can rise. Furthermore, the reading can be taken according to the position covered by the mud, and the thickness of the sediment can be obtained. It is simple and convenient, without manual operation, improving work efficiency.
[0032] Refer to Figure 1 and Figure 2 , The limiting mechanism includes two limiting disks 7. Both limiting disks 7 are sleeved on the rotating column 2. At one end of the top of the two limiting disks 7, fixing seats 10 are fixedly installed. Threaded holes 11 are penetrated through the two fixing seats 10, and fixing bolts 12 are screwed in the threaded holes 11. By rotating the fixing bolts 12, the fixing bolts 12 can be driven to move outward, and thus the connection and fixation of the two fixing seats 10 can be released.
[0033] Refer to Figure 2 , The two limiting disks 7 are circular and fit closely with the rotating column 2. By setting the two limiting disks 7 to be circular and fit closely with the rotating column 2, it is convenient for installation and limitation.
[0034] Refer to Figure 1 , On the top outer wall of the other support frame 1, a fixing frame 9 is fixedly installed. On one side outer wall of the fixing frame 9, a long box 8 is fixedly installed. By setting the fixing frame 9, the long box 8 can be installed on it.
[0035] Refer to Figure 1 and Figure 3 , The long box 8 is located above one side of the rotating column 2. A long groove 15 is opened on the bottom outer wall of the long box 8. By setting the long groove 15, it can play a role in assisting installation.
[0036] Refer to Figure 3A second support plate 13 is fixedly mounted on one side outer wall of the long box 8, a second motor 14 is fixedly mounted on the top outer wall of the second support plate 13, an output end of the second motor 14 penetrates one side outer wall of the long box 8 and is fixedly mounted with a screw 16, and the screw 16 is a bidirectional thread, and an abutment plate 17 is symmetrically screwed on the screw 16. By starting the second motor 14, the output end of the second motor 14 will drive the screw 16 to rotate, and the rotation of the screw 16 will drive the two abutment plates 17 to move away from each other, thereby releasing the abutment limit on the rotating column 2.
[0037] Reference Figure 3 The outer walls of the two abutment plates 17 that are close to each other are both provided with anti-skid pads, and the two abutment plates 17 are both in contact with the rotating column 2. The friction force can be increased by providing the anti-skid pads.
[0038] Reference Figure 1 and Figure 3 , the length of the two abutment plates 17 is longer than the length of the rotating column 2. By setting the length of the two abutment plates 17 to be longer than the length of the rotating column 2, the contact area can be increased, thereby enhancing the limiting effect.
[0039] The implementation principle of the present application is as follows: when in use, the device is first installed above the pile hole to be detected, and then the second motor 14 is started, so that the output end of the second motor 14 drives the screw 16 to rotate, and the rotation of the screw 16 drives the two abutment plates 17 to move away from each other, thereby releasing the abutment limit of the rotating column 2;
[0040] At this time, the detector body 6 can be connected to the anti-drop rope 5, and then the first motor 4 can be started. The output end of the first motor 4 will drive the rotating column 2 to rotate and the anti-drop rope 5 will also rotate and move downward. Since the detector body 6 has a certain weight inside, the anti-drop rope 5 moves downward, which will drive the detector body 6 to move downward and move to the bottom of the sediment and abut against it. When the detector body 6 no longer moves downward, the anti-drop rope 5 will bend. Then the first motor 4 can be started to reverse so that the detector body 6 can rise, and then the reading can be taken according to the position covered by the mud, and the thickness of the sediment can be obtained. It is simple and convenient, does not require manual operation, has high safety, and improves work efficiency.
