Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grouting density detection, and particularly relates to a sleeve grouting density detection device and a detection method thereof. BACKGROUND

[0002] Steel sleeve grouting connection is a main connection mode of a fabricated concrete structure component, and its working principle is based on high compressive strength and micro-expansion characteristics of grouting material in the sleeve. When subjected to the constraint of the sleeve, a large normal stress is generated between the grouting material and the sleeve, and the steel bar generates friction force through the normal stress, so as to transmit the axial stress of the steel bar. Therefore, when the grouting material is not dense, the transmission of the axial force of the steel bar will be affected, and then the safety of the structure will be greatly affected. However, in actual engineering, the density of the steel sleeve grouting, as a concealed engineering, is often not satisfactory. How to ensure the grouting density of the steel sleeve connection is one of the key problems of the construction quality control of the fabricated concrete structure. After some cylindrical or square columns are completed, the grouting density inside the columns needs to be detected. The detection equipment in the prior art cannot detect all angles of the column, and therefore an efficient detection device is needed to detect the grouting density of the grouting material in the sleeve of the column. SUMMARY

[0003] The present application aims to provide a sleeve grouting density detection device and a detection method thereof to solve the above technical problems.

[0004] The technical scheme of the present application is as follows:

[0005] A sleeve grouting density detection device comprises a platform, a C-shaped seat, a detection mounting frame and a detection mechanism. The C-shaped seat is installed on the platform, the detection mounting frame is arranged on the C-shaped seat, and the detection mechanism is arranged on the detection mounting frame.

[0006] The detection mounting frame comprises a first support, a second support, a third support, a connecting rod mechanism and a lifting mechanism. The first support is fixedly arranged on the upper end surface of the C-shaped seat. The first support, the second support and the third support are arranged in layers. The connecting rod mechanism is arranged on both sides of the first support and is in transmission connection with the second support and the third support. The lifting mechanism is arranged on the C-shaped seat and is in transmission connection with the second support. The lifting mechanism drives the second support to move in the upward and downward directions.

[0007] The connecting rod mechanism comprises long connecting rods and short connecting rods. Two long connecting rods are arranged. One short connecting rod is hingedly arranged at each end of each long connecting rod. The middle portions of the two long connecting rods are hingedly arranged and rotatably arranged on the second support. The two short connecting rods above the two long connecting rods are hingedly arranged on the third support. The two short connecting rods below the two long connecting rods are hingedly arranged on the first support.

[0008] Furthermore, the first, second, and third supports have the same structure. The first support is arranged in a U-shape. An outer limiting support is provided on each side of the inner ring of the first support. The outer limiting support includes an outer limiting rod, an outer limiting roller, and an outer limiting spring. The outer limiting rod is slidably inserted into the first support. The outer limiting roller is rotatably disposed on the outer limiting rod on the side close to the inner ring of the first support.

[0009] Furthermore, an inner limiting bracket is provided on each side of the inner ring of the first bracket. The inner limiting bracket includes an inner limiting rod, an inner limiting seat, an inner limiting roller, and an inner limiting nut. The inner limiting nut is rotatably mounted on the first bracket. The inner limiting rod is inserted into the first bracket. The outer side wall of the inner limiting rod is provided with an external thread, and the inner side wall of the inner limiting nut is provided with an internal thread. The external thread on the inner limiting rod and the internal thread of the inner limiting nut mesh with each other. Rotating the inner limiting nut controls the adjustment of the inner limiting rod on the first bracket. The inner limiting seat is hinged to the inner limiting rod on the side near the inner ring of the first bracket. Two inner limiting rollers are provided, and the two inner limiting rollers are rotatably mounted on the inner limiting seat.

[0010] Furthermore, the detection mechanism includes a vibration wave generator, a vibration wave receiver, and a detection bracket. Two detection brackets are provided, symmetrically arranged on the inner sidewall of the first bracket. The vibration wave generator is mounted on one detection bracket, and the vibration wave receiver is mounted on the other detection bracket.

[0011] Furthermore, the detection bracket includes a detection motor, a detection lead screw, a detection sliding sleeve, and detection connecting rods. The detection lead screw is rotatably mounted on the first bracket, and the detection motor is driven to the detection lead screw. Two detection sliding sleeves are provided, each with a lead screw groove. The two detection sliding sleeves are respectively fitted onto both sides of the detection lead screw, and the lead screw grooves mesh with the detection lead screw. Two detection connecting rods are provided, with one end of each connecting rod hinged to a vibration wave generator and / or a vibration wave receiver, and the other end of each connecting rod hinged to the detection sliding sleeves on both sides.

[0012] Furthermore, the lifting mechanism includes a lifting motor, a lifting screw, and a lifting frame. The lifting screw is rotatably mounted on a C-shaped seat, and the lifting motor is driven to the lifting screw. The lifting frame is mounted on the C-shaped seat to limit the top of the lifting screw. A screw sleeve is provided on the side of the second bracket near the lifting mechanism, and the screw sleeve on the second bracket meshes with the lifting screw.

[0013] Furthermore, it also includes a rotary motor, which is mounted on a platform. A rotating shaft is provided on the platform, and the rotary motor is driven to the rotating shaft. The rotating shaft meshes with the outer wall of the C-shaped seat, and the C-shaped seat is rotatably mounted on the platform.

[0014] Furthermore, the lower end face of the platform is provided with casters, and a push handle is provided on the platform.

[0015] A method for detecting the compactness of grouting sleeves includes the following steps:

[0016] S1: The staff moves the handrail control platform to the sleeve to be tested, so that the sleeve is in the concave part of the C-shaped seat;

[0017] S2: The sleeve is fitted onto the inner and outer limiting brackets on the first, second, and third brackets. The inner limiting roller on the inner limiting bracket is in contact with the sleeve, and the outer limiting roller on the outer limiting bracket is in contact with the sleeve.

[0018] S3: Start the detection mechanism and use the detection mechanisms on the first, second and third supports to detect the grouting density at different heights in the sleeve;

[0019] S4: Start the rotary motor, which drives the rotating shaft, which in turn drives the C-shaped seat to rotate around the sleeve, so that the detection mechanisms on the first, second, and third supports can respectively detect the grouting density around the sleeve.

[0020] S5: Start the lifting mechanism, drive the second support to rise gradually through the lifting mechanism, and drive the third support to rise synchronously through the linkage mechanism. While the second and third supports are rising, the rotary motor continues to run back and forth, so that the detection devices on the second and third supports can detect the grouting density at different heights and areas of the sleeve.

[0021] S6: After completing the inspection of a single sleeve, control the rotary motor, lifting mechanism and inspection mechanism to reset, so that the center of the inspection equipment is lowered and the inspection equipment is moved to other sleeves for inspection.

[0022] Furthermore, before the testing process, the testing agency drives the testing screw to rotate via the testing motor. The rotation of the testing screw causes the testing sliding sleeves on both sides to move towards each other, thereby causing the testing connecting rods on both sides to push the vibration wave generator and / or vibration wave receiver towards the sleeve and make contact with it. Then, the vibration wave generator is activated to generate vibration waves towards the sleeve. The vibration wave receiver receives the generated vibration waves, and the grouting density of the current area of ​​the sleeve is obtained by judging the state of the received vibration waves.

[0023] This invention provides an improved detection method for a sleeve grouting density testing device, which, compared with the prior art, has the following improvements and advantages:

[0024] Firstly, this invention places the sleeve within the concave portion of the C-shaped seat; the sleeve is embedded in the inner and outer limiting brackets on the first, second, and third supports, with the inner limiting roller on the inner limiting bracket contacting the sleeve, and the outer limiting roller on the outer limiting bracket abutting against the sleeve; the detection motor drives the detection screw to rotate, and the rotation of the detection screw causes the detection sliding sleeves on both sides to move towards each other, thereby causing the detection connecting rods on both sides to push the vibration wave generator and / or vibration wave receiver towards the sleeve and make contact with it, and then the vibration wave generator is activated to generate vibration waves towards the sleeve, and the vibration wave receiver receives the generated vibration waves, and the grouting density of the current area of ​​the sleeve is obtained by judging the state of the received vibration waves, and the grouting density is detected at different heights in the sleeve by the detection mechanisms on the first, second, and third supports respectively.

[0025] Secondly, in this invention, a rotary motor drives a rotating shaft, which in turn drives a C-shaped seat to rotate around the sleeve. This allows the detection mechanisms on the first, second, and third supports to perform grout density testing on the circumference of the sleeve. The lifting mechanism is then activated, which drives the second support to gradually rise. The linkage mechanism simultaneously drives the third support to rise. While the second and third supports are rising, the rotary motor continues to reciprocate, enabling the detection devices on the second and third supports to perform grout density testing on different heights and areas of the sleeve.

Detailed Implementation

[0037] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides an improved device for detecting the compactness of grouting in sleeves, such as... Figures 1-8 As shown, it includes a platform 1, a C-shaped base 2, a testing mounting frame 3, and a testing mechanism 4.

[0039] The testing mounting frame 3 includes a first bracket 31, a second bracket 32, a third bracket 33, a linkage mechanism 34, and a lifting mechanism 35. The first bracket 31 is fixedly mounted on the upper surface of the C-shaped seat 2. The first bracket 31, the second bracket 32, and the third bracket 33 are stacked. By setting the first bracket 31, the second bracket 32, and the third bracket 33, the grouting density of different height areas of the sleeve can be tested. The linkage mechanism 34 is located on both sides of the first bracket 31 and is connected to the second bracket 32 ​​and the third bracket 33. The lifting mechanism 35 is located on the C-shaped seat 2. The second support 32 is connected to the base 2 via a transmission mechanism 35. The lifting mechanism 35 drives the second support 32 to move up and down. The lifting mechanism 35 can control the lifting action of the second support 32. When the second support 32 is lifted, the power is transmitted to the third support 33 through the linkage mechanism 34, so that the third support 33 is lifted and lowered synchronously. This can ensure the uniformity and stability of the grouting density test. By setting the first support 31, the second support 32 and the third support 33, the efficiency of grouting density test can be improved and multiple tests can be performed on some areas.

[0040] The linkage mechanism 34 includes a long link 341 and a short link 342. Two long links 341 are provided, and a short link 342 is hinged to each end of each long link 341. The middle parts of the two long links 341 are hinged to each other and rotatably mounted on the second bracket 32. The two short links above the two long links 341 are respectively hinged to the third bracket 33, and the two short links below the two long links 341 are respectively hinged to the first bracket 31.

[0041] Preferably, the first support 31, the second support 32 and the third support 33 have the same structure. The first support 31 is arranged in a U-shape. The U-shape can facilitate the embedding of a square or cylindrical sleeve inside the first support 31, so as to facilitate the subsequent grouting density test.

[0042] An outer limiting bracket 36 is provided on each side of the inner ring of the first bracket 31. The outer limiting bracket 36 includes an outer limiting rod 361, an outer limiting roller 362 and an outer limiting spring 363. The outer limiting rod 361 is slidably inserted into the first bracket 31. The outer limiting roller 362 is rotatably disposed on the outer limiting rod 361 on the side close to the inner ring of the first bracket 31. The outer limiting spring 363 is sleeved on the outer limiting rod 361 and pushes the outer limiting roller 362 toward the inner side of the first bracket 31.

[0043] An inner limiting bracket 37 is provided on each side of the inner ring of the first bracket 31. Each inner limiting bracket 37 includes an inner limiting rod 371, an inner limiting seat 372, inner limiting rollers 373, and an inner limiting nut 374. The inner limiting nut 374 is rotatably mounted on the first bracket 31. The inner limiting rod 371 is inserted into the first bracket 31. The outer side wall of the inner limiting rod 371 has an external thread, and the inner side wall of the inner limiting nut 374 has an internal thread. The external thread on the inner limiting rod 371 and the internal thread on the inner limiting nut 374 mesh with each other. Rotating the inner limiting nut 374 controls the adjustment of the inner limiting rod 371 on the first bracket 31. The inner limiting seat 372 is hinged to the inner limiting rod 371 on the side near the inner ring of the first bracket 31. Two inner limiting rollers 373 are provided, and the two inner limiting rollers 373 are rotatably mounted on the inner limiting seat 372.

[0044] The sleeve is limited by setting an inner limit bracket 37 and an outer limit bracket 36 on the first bracket 31, the second bracket 32 ​​and the third bracket 33 respectively. When the C-shaped seat 2 rotates, the inner limit bracket 37 and the outer limit bracket 36 generate a thrust to keep the sleeve in the middle of the C-shaped seat 2.

[0045] The detection mechanism 4 includes a vibration wave generator 41, a vibration wave receiver 42, and a detection bracket 43. Two detection brackets 43 are provided, symmetrically arranged on the inner side wall of the first bracket 31. The vibration wave generator 41 is mounted on one detection bracket 43, and the vibration wave receiver 42 is mounted on the other detection bracket 43. The vibration wave generator 41 can generate vibration waves on the sleeve, and the vibration wave receiver 42 can receive the generated vibration waves. The detection brackets 43 allow the vibration wave generator 41 and the vibration wave receiver 42 to be close to the sleeve to be tested, so as to facilitate the generation and reception of vibrations by the vibration wave generator 41 and the vibration wave receiver 42.

[0046] The detection bracket 43 includes a detection motor 431, a detection lead screw 432, a detection sliding sleeve 433, and detection connecting rods 434. The detection lead screw 432 is rotatably mounted on the first bracket 31. The detection motor 431 is driven to the detection lead screw 432. Two detection sliding sleeves 433 are provided, each with a lead screw groove. The two detection sliding sleeves 433 are respectively fitted on both sides of the detection lead screw 432, and the lead screw grooves mesh with the detection lead screw 432. Two detection connecting rods 434 are provided, and one end of each detection connecting rod 434 is hinged to the vibration wave generator 41 and / or On the vibration wave receiver 42, the other ends of the two detection rods 434 are respectively hinged to the detection sliding sleeves 433 on both sides. In use, a position sensor can be set to determine the distance between the sleeve and the vibration wave generator 41 and / or the vibration wave receiver 42. The detection motor 431 is started to drive the detection screw 432 to rotate. The detection screw 432 drives the detection sliding sleeve 433 to move. The detection rods 434 can transmit power to the vibration wave generator 41 and / or the vibration wave receiver 42 to control the vibration wave generator 41 and / or the vibration wave receiver 42 to move closer to or away from the sleeve.

[0047] The lifting mechanism 35 includes a lifting motor 351, a lifting screw 352, and a lifting frame 353. The lifting screw 352 is rotatably mounted on the C-shaped seat 2. The lifting motor 351 is driven by the lifting screw 352. The lifting frame 353 is mounted on the C-shaped seat 2 and limits the top of the lifting screw 352. A screw sleeve is provided on the side of the second bracket 32 ​​near the lifting mechanism 35. The screw sleeve on the second bracket 32 ​​meshes with the lifting screw 352. The lifting motor 351 drives the lifting screw 352 to rotate, and the lifting frame 353 limits the lifting screw 352, thereby ensuring the stability of the lifting screw 352. Through the interaction between the lifting screw 352 and the screw sleeve on the second bracket 32, the height of the second bracket 32 ​​can be adjusted vertically.

[0048] It also includes a rotary motor 5, which is mounted on a platform 1. A rotating shaft 51 is provided on the platform 1. The rotary motor 5 is driven to the rotating shaft 51. The rotating shaft meshes with the outer wall of the C-shaped seat 2. The C-shaped seat 2 is rotatably mounted on the platform 1. The rotary motor 5 can drive the C-shaped seat 2 to rotate on the platform 1, thereby ensuring that the equipment can perform more comprehensive inspection of the circumference of the sleeve.

[0049] The lower end of platform 1 is equipped with casters, which make it easier for staff to move and adjust the equipment. Platform 1 is also equipped with a push handle, which makes it easier for users to control and push the equipment.

[0050] A method for detecting the compactness of grouting sleeves includes the following steps:

[0051] S1: The staff moves the handrail control platform 1 to the sleeve to be tested, so that the sleeve is in the concave part of the C-shaped seat 2;

[0052] S2: The sleeve is fitted onto the inner limiting bracket 37 and the outer limiting bracket 36 on the first bracket 31, the second bracket 32, and the third bracket 33. The inner limiting roller 373 on the inner limiting bracket 37 is in contact with the sleeve, and the outer limiting roller 362 on the outer limiting bracket 36 is in contact with the sleeve.

[0053] S3: Start the detection mechanism 4, and use the detection mechanisms 4 on the first support 31, the second support 32 and the third support 33 to detect the grouting density at different heights in the sleeve respectively;

[0054] S4: Start the rotary motor 5, which drives the rotating shaft 51, which in turn drives the C-shaped seat 2 to rotate around the sleeve, so that the detection mechanisms 4 on the first support 31, the second support 32 and the third support 33 respectively perform grouting density detection on the circumference of the sleeve.

[0055] S5: Start the lifting mechanism 35, drive the second support 32 to rise gradually through the lifting mechanism 35, and drive the third support 33 to rise synchronously through the linkage mechanism 34. While the second support 32 and the third support 33 are rising, the rotary motor 5 continues to reciprocate, so that the detection devices on the second support 32 and the third support 33 can detect the grouting density at different heights and areas of the sleeve.

[0056] S6: After completing the inspection of a single sleeve, control the rotary motor 5, lifting mechanism 35 and inspection mechanism 4 to reset, so that the center of the inspection equipment is lowered and the inspection equipment is moved to other sleeves for inspection.

[0057] Before the testing process, the testing mechanism 4 drives the testing screw 432 to rotate via the testing motor 431. The rotation of the testing screw 432 causes the testing sliding sleeves 433 on both sides to move towards each other, thereby causing the testing connecting rods 434 on both sides to push the vibration wave generator 41 and / or vibration wave receiver 42 towards the sleeve and make contact with it. Then, the vibration wave generator 41 is started to generate vibration waves towards the sleeve. The vibration wave receiver 42 receives the generated vibration waves and determines the grouting density of the current area of ​​the sleeve by judging the state of the received vibration waves.

[0058] In use: The operator moves the handrail control platform 1 to the sleeve to be tested, positioning the sleeve within the concave part of the C-shaped seat 2. The sleeve is then fitted into the inner limiting bracket 37 and outer limiting bracket 36 on the first bracket 31, second bracket 32, and third bracket 33. The inner limiting roller 373 on the inner limiting bracket 37 contacts the sleeve, while the outer limiting roller 362 on the outer limiting bracket 36 abuts against the sleeve. The detection motor 431 drives the detection screw 432 to rotate, causing the detection sliding sleeves 433 on both sides to move towards each other. This causes the detection connecting rods 434 on both sides to push the vibration wave generator 41 and / or vibration wave receiver 42 towards the sleeve, bringing them into contact. The vibration wave generator 41 is then activated to generate vibration waves towards the sleeve. The vibration wave receiver 42 receives the generated vibration waves and determines the grouting density of the current area of ​​the sleeve by judging the received vibration wave state. The first bracket 31 and second bracket 32... The detection mechanism 4 on the first support 31, the second support 32, and the third support 33 respectively perform grout density testing at different heights within the sleeve; the rotary motor 5 is started, which drives the rotating shaft 51, which in turn drives the C-shaped seat 2 to rotate around the sleeve, allowing the detection mechanisms 4 on the first support 31, the second support 32, and the third support 33 to perform grout density testing around the sleeve; the lifting mechanism 35 is started, which drives the second support 32 to gradually rise, and the linkage mechanism 34 simultaneously drives the third support 33 to rise, while the rotary motor 5 continues to reciprocate as the second support 32 and the third support 33 rise, enabling the detection devices on the second support 32 and the third support 33 to perform grout density testing at different heights and areas of the sleeve; after the testing of a single sleeve is completed, the rotary motor 5, the lifting mechanism 35, and the detection mechanism 4 are reset, lowering the center of the detection equipment and moving the detection equipment to other sleeves for testing.

[0059] The vibration wave generator 41 in this application can release vibration waves into the sleeve, and the vibration wave receiver 42 can receive the vibration waves in the sleeve. In use, the vibration wave generator 41 and the vibration wave receiver 42 are set facing each other. The vibration wave generated by the vibration wave generator 41 passes through the sleeve and is transmitted by the internal mechanism inside the sleeve. The vibration wave is received by the vibration wave receiver 42. The higher the grout density inside the sleeve, the higher the transmission stability of the vibration wave and the clearer the received waveform. The lower the grout density inside the sleeve, the lower the transmission stability of the vibration wave and the relatively scattered the received waveform. When there are holes in the grout inside the sleeve, the vibration wave will be deformed when passing through the hole area. At this time, the vibration signal received by the vibration wave receiver 42 is very chaotic, which enables the detection of the grout density in the sleeve.
