[0034] As Figures 1 to 7As shown in the figure, the present invention provides a technical solution: a peeling device for the attachment of a pulling block used in construction engineering inspection, which includes a pulling barrel 1, and handles 2 provided at the top ends of the outer walls on both sides of the pulling barrel 1 to facilitate the movement of the pulling barrel 1, a peeling assembly 3 provided on the inner walls on both sides of the pulling barrel 1, and the peeling assembly 3 is used to uniformly strike the steel bar sleeve 409 to reduce the damage to the steel bar sleeve 409 during peeling;

[0035] A fixing assembly 4 is provided at the top end of the pulling barrel 1, and the fixing assembly 4 is used to fix the steel bar after the pulling test;

[0036] The peeling assembly 3 includes a sleeve 309. The sleeve 309 is provided on both sides of the top end of the inner wall of the pulling barrel 1. One outer wall of the sleeve 309 is fixedly connected to the inner wall of the pulling barrel 1. A sliding hole 310 is opened on the outer wall of the sleeve 309. A knocking rod 303 is slidably connected to the inner wall of the sleeve 309. A tooth groove 311 is opened on the outer wall of the knocking rod 303. A first half gear 313 and a second half gear 314 are respectively meshed with the inner walls of the two tooth grooves 311, and the teeth on the first half gear 313 and the second half gear 314 are arranged in opposite directions. When the teeth in different directions on the first half gear 313 and the second half gear 314 rotate, they respectively mesh with the tooth groove 311 on the outer wall of the knocking rod 303, so as to drive the two knocking rods 303 to strike the steel bar sleeve 409 respectively, ensuring the uniformity and symmetry of the knocking.

[0037] As Figures 1 to 7As shown in the figure, the stripping component 3 includes a sleeve 309 which is arranged on both sides of the top end of the inner wall of the drawing barrel 1. One outer wall of the sleeve 309 is fixedly connected to the inner wall of the drawing barrel 1. A sliding hole 310 is provided on the outer wall of the sleeve 309. A knocking rod 303 is slidably connected to the inner wall of the sleeve 309. A tooth groove 311 is provided on the outer wall of the knocking rod 303. A first half gear 313 and a second half gear 314 are respectively meshed and connected to the inner walls of the two tooth grooves 311, and the teeth on the first half gear 313 and the second half gear 314 are arranged in opposite directions. A rotating rod 312 is fixedly connected to the central holes of the first gear and the second half gear 314. One end of the rotating rod 312 is rotatably connected to the inner wall of the drawing barrel 1. The other end of the rotating rod 312 penetrates through the outer wall of the drawing barrel 1 and is fixedly connected to a rotating disk 301. A turning handle 302 is arranged on the outer wall of one side of the turntable. The top end of the knocking rod 303 penetrates through the top end of the drawing barrel 1 and is fixedly connected to a limiting block 305. A soft pad 304 is fixedly connected to the bottom end of the limiting block 305. A fixing plate 307 is fixedly connected to the inner wall of the drawing barrel 1. A guide sleeve 308 is fixedly connected to the inner wall of the central hole at the top end of the fixing plate 307. A limiting plate 306 is arranged on the inner wall of the drawing barrel 1. The limiting plate 306 is arranged below the sleeve 309, and there is a certain distance between the limiting plate 306 and the sleeve 309. Specifically, after the steel bar sleeve 409 is fixed inside the drawing barrel 1 through the fixing component 4, the turning handle 302 is shaken to drive the rotating disk 301 to rotate, thereby driving the rotating rod 312 fixedly connected to the outer wall of the other side of the rotating disk 301 to rotate inside the drawing barrel 1. While the rotating rod 312 rotates, the first half gear 313 and the second half gear 314 fixedly connected to the outer walls of both ends are driven to rotate. When rotating, the teeth on the outer walls of the first half gear 313 and the second half gear 314 sequentially pass through the sliding hole 310 and are respectively meshed with the tooth grooves 311 on both sides, ensuring the stability and high efficiency of the transmission. And because the teeth of the first half gear 313 and the second half gear 314 are in different directions, the two knocking rods 303 on both sides can be driven to rise in sequence when rotating. When the first half gear 313 and the second half gear 314 respectively rotate to the side without teeth, the two knocking rods 303 on both sides will fall in sequence and knock on the top ends of both sides of the steel bar sleeve 409 in sequence, so that the steel bar sleeve 409 falls off from the outer wall of the fixing block 410. This device can ensure that the steel bar sleeve 409 is evenly stressed during the knocking process, realize continuous and rapid knocking actions, improve the construction efficiency, and at the same time can effectively reduce the local damage of the steel bar sleeve 409 caused by different manual knocking forces. When the knocking rod 303 falls to knock on the steel bar sleeve 409, the limiting block 305 arranged at the top end of the knocking rod 303 contacts the drawing barrel 1. The limiting block 305 can effectively limit the position of the knocking rod 303 and prevent it from slipping out of the sleeve 309, thereby ensuring the stability of the knocking process. And the soft pad 304 arranged at the bottom end of the limiting block 305 can disperse the pressure during impact and absorb the impact force, and can protect the impact surface between the limiting block 305 and the drawing barrel 1, reducing the wear and damage caused by knocking.It should also be clear that in this embodiment, the peeling processes after non-destructive testing and destructive testing are different. When peeling the attachments of the pulled steel bar 408 during non-destructive testing, first align the bottom of the pulling barrel 1 with the steel bar sleeve 409 and press downwards, so that the steel bar sleeve 409 slides and inserts into the interior of the pulling barrel 1, and fix the pulled steel bar 408 through the fixing component 4, thereby fixing the steel bar sleeve 409 inside the pulling barrel 1. Subsequently, after completing the peeling operation, rotate the rotating cylinder 403 to make the pressing plate 406 rebound outwards, so that the pulled steel bar 408 becomes loose. Then, pull the pulling barrel 1 outwards through the handle 2, so that the pulled steel bar 408 slides out of the interior of the pressing plate 406 along the guide sleeve 308, and thus the pulling barrel 1 can be smoothly removed. Subsequently, collect the peeled-off objects. When peeling the attachments of the pulled steel bar 408 during destructive testing, repeat the previous step to fix the pulled steel bar 408 and the steel bar sleeve 409 inside the pulling barrel 1. Then, pull the handle 2 and place the pulling barrel 1 on the ground. Since destructive testing will break the pulled steel bar 408 or pull out the pulled steel bar 408 along the inside of the structural adhesive, the pulled steel bar 408 and the steel bar sleeve 409 will also move along with the pulling barrel 1. After completing the peeling operation, hold the top end of the pulled steel bar 408 and rotate the rotating cylinder 403 to make the pressing plate 406 rebound outwards, so that the pulled steel bar 408 becomes loose. Then, pull the top end of the pulled steel bar 408 and pull out the pulled steel bar 408 upwards along the guide sleeve 308 and the inner wall of the pressing plate 406, so that the peeled-off objects can be collected. Since the peeling device for the attachments of the pulling block used in this building engineering inspection can simultaneously satisfy the peeling of the attachments of the pulled steel bar 408 after non-destructive testing and destructive testing, the inspection process is more flexible, and the appropriate inspection sequence and method can be selected according to actual needs.

[0038] Such as Figures 1 to 7As shown, the fixing component 4 includes a fixing hole 401 which is opened at the top end of the drawing barrel 1. The inner wall of the fixing hole 401 is fixedly connected with a fixing cylinder 402. A threaded groove 405 is opened on the inner wall of the fixing cylinder 402. An extrusion plate 406 is arranged at the bottom end of the inner wall of the fixing cylinder 402. Through holes 407 are opened on the outer wall of the extrusion plate 406. A slope 404 is opened at the top end of the outer wall of the extrusion plate 406. A rotating cylinder 403 is rotatably connected to the inner wall of the fixing cylinder 402. A slope 404 is also opened on the inner wall of the rotating cylinder 403. The two slopes 404 cooperate with each other. A drawing steel bar 408 is slidably connected to the inner wall of the extrusion plate 406. A fixing block 410 is fixedly connected to the outer wall of the drawing steel bar 408. A steel bar sleeve 409 is slidably connected to the outer wall of the fixing block 410. Specifically, by aligning the bottom of the drawing barrel 1 with the steel bar sleeve 409 through the handle 2 and pressing downwards, the steel bar sleeve 409 is slidably inserted into the drawing barrel 1. At the same time, the drawing steel bar 408 slides into the central holes of the extrusion plate 406 and the rotating cylinder 403 through the guide sleeve 308. When the steel bar sleeve 409 slides a certain distance inside the drawing barrel 1, its top end fits against the bottom end of the limiting plate 306, thereby realizing the limitation of the steel bar sleeve 409. It should also be clear that in this embodiment, the limiting plate 306 can accurately control the insertion depth of the steel bar sleeve 409, prevent the steel bar sleeve 409 from being inserted too deep or too shallow, and ensure its accurate position in the drawing barrel 1. Subsequently, the rotating cylinder 403 is rotated so that the thread on its outer wall meshes with the threaded groove 405 on the inner wall of the fixing cylinder 402, thereby causing the rotating cylinder 403 to move downwards along the inner wall of the fixing cylinder 402. When moving, the slope 404 at the bottom end of the inner wall of the rotating cylinder 403 contacts the slope 404 at the top end of the outer wall of the extrusion plate 406. Since the two slopes 404 are in opposite directions, a uniform radial pressure can be provided when it is pressed downwards. At the same time, the through holes 407 opened on the outer wall of the extrusion plate 406 enable the extrusion plate 406 to contract inwards more uniformly, thereby better fixing the drawing steel bar 408. Thus, the extrusion plate 406 gradually contracts inwards to fix the drawing steel bar 408, and the fixing block 410 and the steel bar sleeve 409 on the outer wall of the drawing steel bar 408 are fixed inside the drawing barrel 1. This device can ensure that the extrusion plate 406 is evenly stressed during the contraction process and accurately control its contraction degree through the meshing of the thread and the threaded groove 405 and the cooperation of the two slopes 404 on both sides, thereby improving the reliability of fixing the drawing steel bar 408.

[0039] When it is necessary to strip the tested steel bars, the corresponding stripping process needs to be performed according to the testing method used. Hold the handle 2 and press the bottom of the drawing barrel 1 against the steel bar sleeve 409 downward, so that the steel bar sleeve 409 slides and inserts into the inside of the drawing barrel 1. At the same time, the drawn steel bar 408 passes through the guide sleeve 308 and slides into the central holes of the pressing plate 406 and the rotating cylinder 403. When the steel bar sleeve 409 slides a certain distance and fits with the limit plate 306, the steel bar sleeve 409 is limited, ensuring its accurate position in the drawing barrel 1. Subsequently, rotate the rotating cylinder 403 so that the rotating cylinder 403 moves downward along the inner wall of the fixed cylinder 402, thereby driving the pressing plate 406 to gradually contract inward to fix the drawn steel bar 408, so that the fixing block 410 on the outer wall of the drawn steel bar 408 and the steel bar sleeve 409 are fixed inside the drawing barrel 1. Through the engagement of the thread and the thread groove 405 and the cooperation of the two slopes 404, it can ensure that the pressing plate 406 is evenly stressed during the contraction process, improving the reliability of fixing the drawn steel bar 408. Subsequently, shake the turning handle 302 to drive the rotating disc 301 to rotate, thereby driving the first half gear 313 and the second half gear 314 fixedly connected to both ends of the rotating rod 312 provided on the outer wall of the other side of the rotating disc 301 to rotate. When rotating, the teeth on the outer walls of the first half gear 313 and the second half gear 314 sequentially pass through the sliding holes 310 and are respectively engaged with the tooth grooves 311 on both sides, ensuring the stability of the transmission. And because the teeth of the first half gear 313 and the second half gear 314 are in different directions, they can drive the two side knocking rods 303 to rise in turn when rotating. When the first half gear 313 and the second half gear 314 rotate to the end without teeth, the knocking rods 303 will fall in turn and knock on the steel bar sleeve 409 in turn, so that the steel bar sleeve 409 falls off from the outer wall of the fixing block 410. This mechanism can ensure that the steel bar sleeve 409 is evenly stressed during the knocking process, avoiding uneven stripping effects caused by uneven stress, and effectively reducing local damage to the steel bar sleeve 409 caused by different manual knocking forces. When the knocking rod 303 falls to knock on the steel bar sleeve 409, the limit block 305 provided at the top of the knocking rod 303 can effectively limit the position of the knocking rod 303 to prevent it from slipping out of the sleeve 309. And the soft pad 304 provided at the bottom of the limit block 305 can protect the impact surface between the limit block 305 and the drawing barrel 1 by dispersing pressure and absorbing impact force, reducing wear and damage caused by knocking. The difference between the stripping processes of non-destructive testing and destructive testing is that in non-destructive testing, when the drawing barrel 1 fixes the drawn steel bar 408, the drawing barrel 1 is fixed on the concrete wall surface, and the drawn steel bar 408 remains in place, and only the steel bar sleeve 409 is stripped. In destructive testing, the drawn steel bar 408 will be broken or pulled out along the inside of the structural adhesive. When the drawing barrel 1 fixes the drawn steel bar 408, pull the handle 2 to place the drawing barrel 1 on the ground.The pulling steel bar 408 and the steel bar sleeve 409 will move together with the pulling barrel 1, and then a peeling operation is performed on them. Although this detection method can more intuitively observe the bonding situation between the steel bar and the concrete, it will cause irreversible damage to the detection object.

[0040] In summary, the present invention includes a pulling barrel 1, and handles 2 provided at the top ends of the outer walls on both sides of the pulling barrel 1. The handles 2 facilitate the movement of the pulling barrel 1. A peeling assembly 3 is provided on the inner walls on both sides of the pulling barrel 1. The peeling assembly 3 is used to evenly strike the steel bar sleeve 409 to reduce damage to the steel bar sleeve 409 during peeling. A fixing assembly 4 is provided at the top of the pulling barrel 1. The fixing assembly 4 is used to fix the steel bar after the pulling test to ensure that the pulling steel bar 408 remains stable during peeling. Through the engagement of the thread and the thread groove 405 and the cooperation of the two slopes 404, the present invention can ensure that the pressing plate 406 is evenly stressed during the contraction process and accurately control its contraction degree, thereby improving the reliability of fixing the pulling steel bar 408. At the same time, since the teeth of the first half gear 313 and the second half gear 314 are in different directions, when rotating, they can drive the two side knocking rods 303 to rise in sequence. When the first half gear 313 and the second half gear 314 rotate to the end without teeth, the knocking rods 303 will fall in sequence and strike the steel bar sleeve 409 in sequence, which can ensure that the steel bar sleeve 409 is evenly stressed during the knocking process, avoid uneven peeling effects caused by uneven stress, effectively reduce local damage to the steel bar sleeve 409 caused by different manual knocking forces, greatly improve the detection speed, reduce manual intervention, and avoid safety risks caused by efficiency decline due to fatigue in manual operations, such as mechanical injuries and dust pollution, and the possible flying out of tools or accidental injuries during manual knocking.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
