Description

Technical Field

[0001] The present invention relates to the technical field of building detection, and particularly relates to a damage detection device for a steel frame - reinforced concrete tube. Background Art

[0002] The reinforced concrete tube is a spatial stress structure mainly composed of steel bars and concrete. Visually, it is a closed or nearly closed tubular structure, and common shapes include circular, square or rectangular. In building structures, the reinforced concrete tube bears the weight of the building itself. For high - rise buildings, this part of the weight is extremely large. And the concrete tube is exposed to the natural environment for a long time, and will be affected by factors such as rain erosion, chemical corrosion, and temperature changes. These factors may cause problems such as carbonation of concrete and corrosion of steel bars. Therefore, a damage detection device for a steel frame - reinforced concrete tube is needed to detect the reinforced concrete tube and avoid accidents.

[0003] In the patent document with the publication number CN217846179U that has been made public, a damage detection device for a reinforced concrete structure is disclosed. It includes a vehicle body. A numerical controller and a limiting rod are fixedly connected to the top surface of the vehicle body respectively. A telescopic frame is slidably sleeved between the limiting rods. An electric push rod I is installed between the telescopic frame and the top surface of the vehicle body. And an electric push rod II is installed inside the side wall of the telescopic frame. A slider is fixedly connected to the output end of the electric push rod II. This detection device can independently complete the detection operation, improving the intelligence level of the detection device. At the same time, the detection height of the detection device is not limited, and it can detect the reinforced concrete structure located at a high place without manual assistance, saving time and effort. Moreover, it can expand the detection range without the vehicle body moving repeatedly many times, not only improving the detection efficiency but also reducing the energy consumption.

[0004] When the above device is in use, it can be quickly transported to the specified position for detection by using the transportation component. However, for the reinforced concrete tube, its shape can be circular, square or rectangular. The current device has a large detection limitation because it cannot perform relative detection corresponding to different shapes of the reinforced concrete tube, resulting in a relatively low overall detection efficiency. And the above - mentioned device has a relatively large overall volume, which is rather troublesome to transport into the reinforced concrete tube, and the detection is rather laborious.

[0005] Therefore, this application proposes a damage detection device for a steel frame - reinforced concrete tube. Summary of the Invention

On the outside of the movable long rod, a groove - card positioning long rod is slidably installed. On one side of the groove - card positioning long rod, a positioning clamping long block is hinged through a positioning bolt. On the side of the movable long rod away from the positioning clamping long block, a universal wheel rod is fixedly installed. On the side of the universal wheel rod away from the movable long rod, an anti - detachment transmission wheel is rotatably installed through a power component. On the outside of the groove - card positioning long rod, a detection component is arranged.

[0010] Optionally, an electric telescopic rod is slidably installed on the side where the movable long rod passes through the groove - card positioning long rod. An auxiliary spring is fixedly installed between the electric telescopic rod and the movable long rod.

[0011] Optionally, the positioning - type transmission component includes a third bevel gear rotatably installed at the bottom of the upper positioning plate, and a second bevel gear is rotatably installed on the top of the lower positioning plate.

[0012] Optionally, a first bevel gear is hinged outside the second bevel gear and the third bevel gear. Two limit linkage blocks are fixedly installed between the lower positioning plate and the positioning bolt columns.

[0013] Optionally, a forward and reverse motor is fixedly installed on one side of the first bevel gear through a limit linkage block, and a group of fixed connecting rods are fixedly installed on both sides of the third bevel gear. The number of the fixed connecting rods is two groups, and the other group of fixed connecting rods is fixedly installed on the outside of the lower positioning plate.

[0014] Optionally, the two groups of fixed connecting rods are arranged in a synchronous rotation state with respect to the third bevel gear and the second bevel gear, and the two limit linkage blocks are arranged to limit the rotation of the two groups of fixed connecting rods.

[0015] Optionally, the transmission frame assembly includes a detachable positioning block fixedly installed on the top of the positioning bolt column, and a first storage runner is arranged inside the detachable positioning block.

[0016] Optionally, a transmission rope is rotatably installed on the outside of the first storage runner, and a second storage runner is rotatably installed on one side of the transmission rope away from the positioning bolt column installed on the upper positioning plate.

[0017] Optionally, the auxiliary detection assembly includes a cavity positioning block fixedly installed on one side of the positioning bolt column installed on the lower positioning plate. A multi-cavity positioning block is slidably installed inside the cavity positioning block. A plurality of limit springs are fixedly installed between the multi-cavity positioning block and the cavity positioning block. A plurality of universal wheels are rotatably installed on one side of the multi-cavity positioning block away from the cavity positioning block.

[0018] Optionally, a plurality of transverse fixing blocks are fixedly installed on the outside of the multi-cavity positioning block through a positioning cavity. An inclined rod is hinged on one side of the transverse fixing block away from the multi-cavity positioning block.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. Through the card slot positioning long rod and the telescopic inclined rod, according to the different body states of the steel frame - reinforced concrete tube, corresponding deflection methods are carried out through the deflection guidance of the positioning transmission component to cope with different detection methods, thereby reducing manual detection, improving the safety of the staff during detection, thus improving the detection efficiency and avoiding accidents.

[0021] 2. Since the first bevel gear is meshed with the third bevel gear and the second bevel gear, the third bevel gear and the second bevel gear rotate in opposite directions, and the two sets of fixed connecting rods connected thereto rotate in opposite directions, and then effectively explore along the inner wall of the steel frame-reinforced concrete cylinder until the steel frame-reinforced concrete cylinder contacts the anti-slip transmission wheel. The two sets of fixed connecting rods are respectively connected to the third bevel gear and the second bevel gear, which can avoid interference between the two sets of fixed connecting rods when they rotate, and the two sets of fixed connecting rods remain in a horizontal state, thereby improving the stability of the anti-slip transmission wheel during transmission;

[0022] 3. The multi-cavity positioning block rotates and crawls synchronously along the steel frame-reinforced concrete cylinder, and the multi-cavity positioning block moves upward along the cavity positioning block under the limit of the limit spring. The multi-cavity positioning block drives the tilt rod to deflect outward through the transverse fixed block. Under normal circumstances, the protective outer arc block wrapped around the multi-cavity positioning block is stretched outward. At this time, the detection component set at the bottom of the protective outer arc block is exposed to the air to detect the inner wall of the steel frame-reinforced concrete cylinder. When not in use, the protective outer arc block is in a closed state, thereby better protecting the detection component and reducing the cost of detection. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] As Figure 1 shown, a steel frame-reinforced concrete tube damage detection device proposed by the present invention includes an external damage protection component 1. A transmission frame component 2 is fixedly installed on one side of the external damage protection component 1. A positioning transmission component 3 is installed inside the external damage protection component 1. A universal detection component 4 for adjusting the detection method according to the shape of the steel frame-reinforced concrete tube is connected to the outside of the positioning transmission component 3. An auxiliary detection component 5 is installed on the side of the external damage protection component 1 away from the transmission frame component 2. The universal detection component 4 changes its measurement method according to the shapes of the cube and the cylindrical tube and the volume of the steel frame-reinforced concrete tube;

[0036] The damage protection external component 1 includes an upper positioning plate 101. A protective sliding cavity plate 104 is fixedly installed at the bottom of the upper positioning plate 101. A lower positioning plate 103 is fixedly installed on the side of the protective sliding cavity plate 104 away from the upper positioning plate 101. Two positioning bolt columns 102 are fixedly installed on the outer sides of both the lower positioning plate 103 and the upper positioning plate 101. The transmission frame assembly 2 includes a detachable positioning block 201 fixedly installed at the top of the positioning bolt column 102. A first storage runner 202 is arranged inside the detachable positioning block 201. A transmission rope 203 is rotatably installed on the outer side of the first storage runner 202. The transmission rope 203 is rotatably installed on one side of the positioning bolt column 102 away from the upper positioning plate 101 and is rotatably installed on a second storage runner 204. When it is necessary to horizontally place the upper positioning plate 101 on the ground, the staff installs the detachable positioning block 201 on one side of the positioning bolt column 102 connected to the upper positioning plate 101. A second storage runner 204 is arranged at the top of the steel frame - reinforced concrete tube. The device is transmitted to the bottom of the steel frame - reinforced concrete tube by using the transmission rope 203, avoiding manual inspection at the bottom of the steel frame - reinforced concrete tube, thereby reducing accidents and ensuring the safety of workers.

[0037] Such as Figures 1 - 8As shown, the positioning transmission component 3 includes a third bevel gear 305 rotatably installed at the bottom of the upper positioning plate 101. A second bevel gear 304 is rotatably installed at the top of the lower positioning plate 103. A first bevel gear 302 is hinged to the outer sides of the second bevel gear 304 and the third bevel gear 305. Two limit linkage blocks 303 are fixedly installed between the lower positioning plate 103 and the positioning bolt column 102. A forward and reverse motor 306 is fixedly installed on one side of the first bevel gear 302 passing through the limit linkage block 303. A group of fixed connecting rods 301 are fixedly installed on both sides of the third bevel gear 305. The number of the fixed connecting rods 301 is two groups. The other group of fixed connecting rods 301 is fixedly installed on the outer side of the lower positioning plate 103. The two groups of fixed connecting rods 301 are arranged in a state of synchronous rotation with respect to the third bevel gear 305 and the second bevel gear 304. The two limit linkage blocks 303 are arranged to limit the rotation of the two groups of fixed connecting rods 301. The motor drives the first bevel gear 302 to rotate along the limit linkage block 303. Since the first bevel gear 302 meshes with the third bevel gear 305 and the second bevel gear 304, the rotation directions of the third bevel gear 305 and the second bevel gear 304 are opposite. Then the rotation directions of the two groups of fixed connecting rods 301 connected thereto are opposite, and then they effectively grope along the inner wall of the steel frame-reinforced concrete cylinder until contact occurs between the steel frame-reinforced concrete cylinder and the anti-detachment transmission wheel 407. The two groups of fixed connecting rods 301 are respectively connected to the third bevel gear 305 and the second bevel gear 304, which can avoid interference during the rotation of the two groups of fixed connecting rods 301. Then the two groups of fixed connecting rods 301 maintain a horizontal state, thereby improving the stability of the anti-detachment transmission wheel 407 during transmission.

[0038] As Figures 1 - 8As shown in the figure, the universal detection component 4 includes an internally threaded block 402 rotatably mounted outside two positioning bolt columns 102. Two groups of telescopic inclined rods 403 are hinged on both sides of the internally threaded block 402. One side of the telescopic inclined rod 403 away from the internally threaded block 402 is hinged with a movable long rod 405. A groove positioning long rod 404 is slidably mounted on the outside of the movable long rod 405. One side of the groove positioning long rod 404 is hinged with a positioning clamping long block 401 through a positioning bolt. One side of the movable long rod 405 away from the positioning clamping long block 401 is provided with a universal wheel rod 406. One side of the universal wheel rod 406 away from the movable long rod 405 is rotatably mounted with an anti-drop transmission wheel 407 through a power component. A detection component is arranged on the outside of the groove positioning long rod 404. When the steel frame-reinforced concrete tube is a small cube or a cylindrical tube, the staff first horizontally place the upper positioning plate 101 and the lower positioning plate 103, that is, the upper positioning plate 101 and the lower positioning plate 103 are parallel to the ground. At this time, the groove positioning long rod 404 is parallel to the positioning clamping long block 401, that is, parallel to the ground. At this time, the state of the groove positioning long rod 404 is fixed by a nut. The transmission frame component 2 is used to convey the components below to the bottom of the steel frame-reinforced concrete tube. At this time, the positioning transmission component 3 drives the third bevel gear 305 and the second bevel gear 304 to deflect along the upper positioning plate 101 and the lower positioning plate 103. Since the bottom of the lower positioning plate 103 is in contact with the ground and the auxiliary detection component 5 serves as a limiting component, the damage prevention external component 1 is in a fixed state, so the two positioning bolt columns 102 remain fixed. The positioning transmission component 3 drives the universal detection component 4 to rotate synchronously. The internally threaded block 402 rotates along the thread on the surface of the positioning bolt column 102 through the telescopic inclined rod 403. Due to the thread of the positioning bolt column 102, the internally threaded block 402 moves upward along the positioning bolt column 102. Then the telescopic inclined rod 403 synchronously moves along the internally threaded block 402 towards the positioning transmission component 3. The telescopic inclined rod 403 is then hinged along the groove positioning long rod 404. The movable long rod 405 moves outward along the groove positioning long rod 404 until the universal wheel rod 406 drives the anti-drop transmission wheel 407 to be in full contact with the surface of the tube of the steel frame-reinforced concrete tube. The power component can be a motor connected to the anti-drop transmission wheel 407. As the motor drives the anti-drop transmission wheel 407 to rotate, the anti-drop transmission wheel 407 attached to the tube surface drives the device to move upward step by step in cooperation with the upward pull of the transmission frame component 2. The detection component can be an ultrasonic detection instrument to perform ultrasonic detection on the steel frame-reinforced concrete tube, or an optical instrument to perform a comprehensive scan on the steel frame-reinforced concrete tube to obtain relevant data. And the four detection components surround the steel frame-reinforced concrete tube and divide it into four areas for bottom-up detection, so as to better meet the detection requirements for the steel frame-reinforced concrete tube being a small cube and a cylindrical tube;

[0039] When the steel frame - reinforced concrete tube is a small cuboid, unlock the limit buckle of a set of telescopic inclined rods 403, so that the built - in threaded block 402 can perform telescopic movement. Deflect a set of card slot positioning long rods 404 along the positioning clamping long block 401 until the anti - detachment transmission wheels 407 are in contact with the ground. The telescopic inclined rods 403 cannot interfere with the anti - detachment transmission wheels 407 due to the telescopic movement. Then, use nuts to fix the state of the card slot positioning long rods 404 at this time. The other set of fixed connecting rods 301 drives the anti - detachment transmission wheels 407 to move upward along the edge of the cuboid in cooperation with the transmission frame assembly 2. Detect according to the above operations, so as to better meet the detection requirements for the steel frame - reinforced concrete tube being a small cuboid;

[0040] If the overall volume of the steel frame - reinforced concrete tube is large and cannot be detected normally, bend both sets of card slot positioning long rods 404 towards the direction of the auxiliary detection component 5, so that the four anti - detachment transmission wheels 407 are attached to the inner wall on one side of the steel frame - reinforced concrete tube. The device slides along the steel frame - reinforced concrete tube, and uses the detection components installed on the auxiliary detection component 5 to detect each position of the steel frame - reinforced concrete tube, so as to better cope with the situation where the overall volume of the steel frame - reinforced concrete tube is large;

[0041] The card slot positioning long rods 404 and the telescopic inclined rods 403 deflect in corresponding ways according to the different body states of the steel frame - reinforced concrete tube through the deflection guidance of the positioning transmission component 3 to cope with different detection methods, thereby reducing manual detection, improving the safety of the staff during detection, thus improving the detection efficiency, avoiding accidents. The movable long rod 405 is slidably installed with an electric telescopic rod 408 on one side passing through the card slot positioning long rod 404. An auxiliary spring 409 is fixedly installed between the electric telescopic rod 408 and the movable long rod 405. When the anti - detachment transmission wheels 407 come into contact with the steel frame - reinforced concrete tube, if the inner wall changes greatly when the device walks along the steel frame - reinforced concrete tube, the auxiliary spring 409 buffers the external pressure, improving the stability of the device.

[0042] In this embodiment, as Figure 9 、 Figure 10As shown, the auxiliary detection component 5 includes a cavity positioning block 502 fixedly installed on one side of the positioning bolt column 102 installed on the lower positioning plate 103, a multi-cavity positioning block 503 is slidably installed inside the cavity positioning block 502, a plurality of limit springs 507 are fixedly installed between the multi-cavity positioning block 503 and the cavity positioning block 502, a plurality of universal wheels 504 are rotatably installed on the side of the multi-cavity positioning block 503 away from the cavity positioning block 502, a plurality of transverse fixing blocks 505 are fixedly installed on the outer side of the multi-cavity positioning block 503 through the positioning cavity, a tilting rod 506 is hinged on the side of the transverse fixing block 505 away from the multi-cavity positioning block 503, a protective outer arc block 501 is hinged on the side of the tilting rod 506 away from the transverse fixing block 505, and a side of the protective outer arc block 501 away from the tilting rod 506 is hinged at the bottom of the positioning bolt column 102. When the steel frame-reinforced concrete cylinder is large, the area to be detected is large. , the detection component needs to work for a long time, and the slot positioning long rod 404 is deflected to rotate and crawl the device along the inner wall of the steel frame-reinforced concrete cylinder, causing the auxiliary detection component 5 to contact and squeeze the inner wall of the steel frame-reinforced concrete cylinder for a long time, then the multi-cavity positioning block 503 rotates and crawls synchronously along the steel frame-reinforced concrete cylinder, and the multi-cavity positioning block 503 moves upward along the cavity positioning block 502 under the limit of the limit spring 507, and the multi-cavity positioning block 503 drives the tilting rod 506 to deflect outward through the horizontal fixed block 505. Under normal circumstances, the protective outer arc block 501 wrapped around the multi-cavity positioning block 503 is stretched outward. At this time, the detection component arranged at the bottom of the protective outer arc block 501 is exposed to the air to detect the inner wall of the steel frame-reinforced concrete cylinder. When not in use, the protective outer arc block 501 is in a closed state, thereby better protecting the detection component and reducing the detection cost.
