Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a string-tensioning and string-clamping device for a pore water pressure gauge. Background Art

[0002] Pore ​​water pressure gauges can be divided into differential resistance type, vibrating string type, piezoresistive type and silicon pressure type according to the instrument type.

[0003] Both vibrating wire pore water pressure gauges and silicon pressure pore water pressure gauges can be used for long-term burial in hydraulic structures or other concrete structures and soils to measure the seepage (pore) water pressure inside the structures or soils, and can simultaneously measure the temperature of the burial point.

[0004] In the prior art, the existing method of stringing and clamping the pore water pressure gauge is to clamp the other end of the steel string with a vise, manually pull the pore water pressure gauge core, and manually adjust the tension. After the tension sensor or frequency detection instrument detects that the set force value or frequency has been reached, the string is fixed by punching or tightening the top screw of the string clamp, so that the string clamp and the other end of the steel string are clamped and fixed. The string is then manually pulled to reach the corresponding frequency, and then fixed by punching or tightening screws. This stringing process is difficult to control the tension on the string, so it is difficult to ensure the stability of the string's vibration frequency, and it is less convenient to operate and has high requirements on manual proficiency.

[0025] See also Figures 1 to 3The embodiment of the present invention provides a pore water pressure gauge string tensioning and clamping device, comprising a bearing structure 10, a string clamping assembly 20 arranged on the top of the bearing structure 10 for clamping the pore water pressure gauge string 51, and a string tensioning assembly 30 arranged on one side of the bearing structure 10 for tightening the pore water pressure gauge string 51, the string clamping assembly 20 comprises a base 21, a stamping component 22 arranged on the top of the base 21 away from the string tensioning assembly 30 for fixing the pore water pressure gauge string 51, and a string clamping component 23 arranged on the side of the stamping component 22 facing the string tensioning assembly 30, the string clamping component 23 comprises a A first slide rail 231 is arranged on the side of the stamping part 22 facing the string-tensioning assembly 30, a sliding member 232 is slidably arranged on the first slide rail 231, and a string clamping structure is arranged on the sliding member 232. The string clamping structure includes a fixing member 234 connected to the sliding member 232 and a supporting member 235 movably connected to the fixing member 234 for clamping the pore water pressure gauge string 51. A bolt structure 236 for moving the supporting member 235 to clamp the pore water pressure gauge string 51 and a first connecting hole 237 for connecting the string-tensioning assembly 30 are threadedly connected to the supporting member 235.

[0026] It can be understood that by placing the pore water pressure gauge 50 on the stamping component 22 and fixing the pore water pressure gauge string 51, the bolt structure 236 is rotated clockwise to drive the abutment 235 to fix the pore water pressure gauge string 51 on the fixing component 234, and the abutment 235 is pulled by the string tensioning assembly 30 to drive the sliding member 232 to move away from the stamping component 22 until the pore water pressure gauge string 51 is tightened, so that the pore water pressure gauge string 51 is only subjected to the tension of the string tensioning assembly 30, thereby making the vibration frequency of the pore water pressure gauge string 51 relatively stable, and by arranging the abutment 235 on the sliding member 232, so that when the abutment 235 moves away from the stamping component 22, there will be no shaking in other directions, which will cause the force on the pore water pressure gauge string 51 to change, thereby improving the stability and work efficiency of the string tensioning process, and the operation is convenient and reduces the requirements for manual proficiency.

[0027] Furthermore, the string tensioning assembly 30 includes a supporting bracket 31 and a second slide rail 32 arranged on the side of the supporting bracket 31 away from the string clamping assembly 20, a counterweight box 33 is slidably arranged on the second slide rail 32, and a counterweight structure 34 is arranged in the counterweight box 33.

[0028] Furthermore, a second connection hole 35 for connecting a steel wire rope 40 is provided at the top end of one side of the counterweight box 33 , and two ends of the steel wire rope 40 are respectively connected to the first connection hole 237 and the second connection hole 35 .

[0029] Furthermore, a telescopic bracket 36 is movably provided in the support bracket 31 . The telescopic bracket 36 is sleeved inside the support bracket 31 and slides in the support bracket 31 .

[0030] It can be understood that by providing the telescopic bracket 36 , the string-tensioning assembly 30 can adapt to bearing structures 10 of different heights.

[0031] Furthermore, a rolling bracket 37 is connected to the top of the telescopic bracket 36 , and at least one rolling member 38 is provided on the rolling bracket 37 .

[0032] It should be noted that, in this embodiment, two rolling elements 38 are provided.

[0033] It should be noted that, by placing the pore water pressure gauge 50 on the stamping component 22 and fixing it, by rotating the bolt structure 236 clockwise to drive the abutment 235 to fix the pore water pressure gauge string 51 on the fixing member 234, by connecting one end of the wire rope 40 to the first connecting hole 237, by connecting the other end of the wire rope 40 to the second connecting hole 35 and winding the wire rope 40 on the rolling member 38, by arranging the counterweight structure 34 in the counterweight box 33, so that the counterweight structure 34 drives the counterweight to move. The counterweight box 33 moves on the second slide rail 32 away from the rolling member 38, and pulls the abutment member 235 through the wire rope 40 to drive the sliding member 232 to move away from the stamping component 22 until the pore water pressure gauge string 51 is tightened. By setting the counterweight box 33 on the second slide rail 32, the counterweight box 33 will not cause shaking in other directions when driving the wire rope 40 to move axially, resulting in changes in the force on the pore water pressure gauge string 51, thereby improving the stability and work efficiency of the string tightening process, and the operation is convenient and reduces the requirements for manual proficiency.

[0034] It can be understood that the mass of the counterweight structure 34 in the counterweight box 33 can be adjusted to accommodate pore water pressure gauges with different force values ​​or frequency requirements.

[0035] Furthermore, the stamping component 22 includes a base 221 disposed on the top of the base 21 and a stamping platform 222 disposed on the top of the base 221 for placing the pore water pressure gauge 50 .

[0036] Furthermore, a placement position 223 for placing the pore water pressure gauge 50 and an avoidance position 224 for avoiding the pore water pressure gauge string 51 are respectively provided at both ends of the top of the punching table 22, and a punching position 225 for clamping the pore water pressure gauge string 51 is also provided between the avoidance position 224 and the placement position 223.

[0037] It should be noted that in this embodiment, a meshing tooth 226 is further provided in the stamping position 225, and the meshing tooth 226 is arranged below the pore water pressure gauge chord 51. A stamping head 60 for fixing the chord is also provided on the top of the meshing tooth 226, and a stamping tooth 61 adapted to the meshing tooth 226 is provided at the bottom of the stamping head 60.

[0038] It can be understood that after the pore water pressure gauge 50 completes the stringing process, the pore water pressure gauge string 51 can be fixed by the punching head 60, and the meshing teeth 226 and the punching teeth 61 adapted to the meshing teeth 226 are provided so that the punching head 60 can fix the pore water pressure gauge string 51 more firmly.

[0039] Furthermore, an elastic structure 238 is provided on the side of the sliding member 232 away from the string clamping member 23 , and both ends of the elastic structure 238 respectively abut against the base 21 and the sliding member 232 . A locking member 239 for locking the sliding member 232 is provided on one side of the sliding member 232 .

[0040] It can be understood that by providing the locking member 239, after the pore water pressure gauge 50 completes the stringing process, the locking member 239 can fix the sliding member 232 to prevent accidental touch from causing changes in the force on the pore water pressure gauge string 51. By providing the elastic structure 238, after the pore water pressure gauge 50 completes the string fixing process, the steel wire rope 40 is unloaded by removing the counterweight structure 34 from the counterweight box 33, and the sliding member 232 is slid toward the stamping component 22 on the first slide rail 231 by the tension of the elastic structure 238. Therefore, after the pore water pressure gauge 50 completes the string fixing process, it only needs to remove the counterweight structure 34 from the counterweight box 33 to make the sliding member slide toward the stamping component 22, thereby avoiding manual adjustment during the next stringing process because the sliding member 232 is too far away from the pore water pressure gauge 50 and cannot be connected.

[0041] Furthermore, a footrest component for abutting against the counterweight box 33 is hingedly connected to the support bracket 31 , and the footrest component is arranged on a side of the second slide rail 32 away from the rolling member 38 .

[0042] Furthermore, the pedal component includes a connecting rod 391 hinged on the support bracket 31, a spherical structure 392 rotatably arranged at one end of the connecting rod 391 toward the counterweight box 33 for abutting against the counterweight box 33, and a pedal structure 393 arranged at the end of the connecting rod 391 away from the counterweight box 33 for lifting the spherical structure 392.

[0043] It should be noted that after the pore water pressure gauge 50 completes the process of fixing the string, because the counterweight structure 34 is still in the counterweight box 33 and the counterweight box 33 rests on the spherical structure 392 and lifts the pedal structure 393, the abutment 235 is still pulled by the wire rope 40, and the tension of the elastic structure 238 of the counterweight structure 34 needs to be removed before the sliding member 232 can slide on the first slide rail 231 toward the stamping component 22.

[0044] It can be understood that by stepping down on the pedal structure 393, the spherical structure 392 is driven by the connecting rod 391 to press against the bottom of the counterweight box 33, pushing the counterweight box 33 to slide toward the rolling element 38 on the second slide rail 32, thereby making it possible to relieve the force of the wire rope 40 without removing the counterweight structure 34, and slide the sliding element 232 on the first slide rail 231 toward the stamping component 22 through the tension of the elastic structure 238.

[0045] In summary, the pore water pressure gauge string tensioning and clamping device in the above-mentioned embodiment of the present invention fixes the pore water pressure gauge on the stamping component and drives the abutment to fix the pore water pressure gauge string on the fixing component by rotating the bolt structure clockwise. The abutment is pulled by the string tensioning assembly to drive the sliding part to move away from the stamping component until the pore water pressure gauge string is tightened, so that the pore water pressure gauge string is only subjected to the tension of the string tensioning assembly, thereby making the vibration frequency of the pore water pressure gauge string more stable. By arranging the abutment on the sliding part, when the abutment moves away from the stamping component, there will be no shaking in other directions, which will cause the force on the pore water pressure gauge string to change, thereby improving the stability and work efficiency of the string tensioning process, and the operation is convenient, reducing the requirement for manual proficiency.
