Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated component detection, in particular to a reinforcing steel bar detection equipment for prefabricated components. BACKGROUND

[0002] The prefabricated component is a prefabricated component as the main force component of the prefabricated component, and the prefabricated component is embedded with reinforcing steel bars on one side and reserved with positioning holes on the other side. When used, the embedded reinforcing steel bars of the prefabricated component are inserted into the positioning holes of the next prefabricated component, and then grouting is performed to assemble multiple prefabricated components. However, the reinforcing steel bars on the prefabricated component may have errors, and when the length of the reinforcing steel bars is longer than the preset hole depth, there will be a problem of gaps at the connection of the prefabricated components. Therefore, it is necessary to perform length pre-detection on the reinforcing steel bars on the prefabricated component.

[0003] Through searching, a positioning detector for prefabricated reinforcing steel bars with a publication number of CN119779228A is disclosed. The prior art can simultaneously detect the depths of all positioning holes by setting a positioning plate close to the front side of the prefabricated component and extending a detection rod into the deepest part of the positioning hole, thereby improving the efficiency of positioning detection, facilitating uniform detection of the holes on the prefabricated component by the staff before use, and comparing and adjusting the to-be-inserted reinforcing steel bars.

[0004] Although the existing device facilitates detection, it still has the problem of inconvenient comparison. After detecting the hole depth, the staff can only roughly compare the gap between the reinforcing steel bars and the holes. If the length of the reinforcing steel bars needs to be adjusted, further measurement is required to determine the adjustment requirement of each reinforcing steel bar. Moreover, due to the large fixed structure of the device, the fixing and dismounting operations are relatively cumbersome, and the device needs to be turned over to expand during the comparison process, which is extremely inconvenient. In view of the above, the present application provides a reinforcing steel bar detection equipment for prefabricated components. SUMMARY

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0020] Please refer to Figures 1-8 The application provides the following technical solutions: The steel bar detection equipment for the fabricated prefabricated component comprises a supporting mechanism 1, a positioning mechanism 2 and a detection mechanism 3. The supporting mechanism 1 is a frame structure extending upward in the vertical direction. The positioning mechanism 2 is arranged at the top of the supporting mechanism 1, and the positioning mechanism 2 comprises a positioning seat 21 and a positioning frame 22. The positioning seat 21 is fixedly arranged at the top of the supporting mechanism 1. Two positioning frames 22 are respectively and horizontally slidably connected with the positioning seat 21. The two positioning frames 22 can approach or move away from each other. The area between the two positioning frames 22 is a prefabricated component clamping and positioning area. The detection mechanism 3 is arranged below the positioning mechanism 2.

[0021] The detection mechanism 3 comprises a detection seat 31 and a detection assembly. The detection seat 31 is slidably connected to the supporting mechanism 1 at one end and can slide vertically along the supporting mechanism 1; the other end of the detection seat 31 extends towards the lower part of the positioning mechanism 2. The detection assembly comprises a plurality of detection pieces 32 arranged on the detection seat 31, the positions of the detection pieces 32 correspond to the positions of the reinforcing bars and positioning holes of the prefabricated component to be detected; the detection pieces 32 are structures that can extend and retract in the vertical direction, and the detection pieces 32 can be inserted into the positioning holes of the prefabricated component.

[0022] Through the structure of the scheme, the detection mechanism 3 with different distribution positions of detection pieces 32 is prepared according to the prefabricated component to be detected. When it is necessary to detect the fabricated prefabricated component, first, the positioning frame 22 of the positioning mechanism 2 is used to clamp the prefabricated block. Then, the corresponding detection mechanism 3 is selected, the detection mechanism 3 and the supporting mechanism 1 are connected, then the detection mechanism 3 is pushed towards the prefabricated component, and the detection piece 32 is inserted into the positioning hole reserved on the prefabricated component. After the detection piece 32 is inserted into the positioning hole, the end of the detection piece contacts the bottom of the positioning hole, thereby compressing the detection piece 32 and shortening the overall length of the detection piece 32. The detection seat 31 is pushed to abut against the surface of the prefabricated component, then the detection seat 31 is pulled away, the overall length of the detection piece 32 is measured, and the depth of the positioning hole on the prefabricated component can be confirmed.

[0023] On the basis of the above-mentioned embodiments, referring to Figure 3 The supporting mechanism 1 comprises a base frame 11 and a stand 12, wherein the base frame 11 is a bottom support structure, and the base frame 11 of the scheme is a horizontal plate body. One stand 12 is arranged at each end of the base frame 11, and the two stands 12 are symmetrically arranged; the detection seat 31 and the stand 12 are slidably connected, and the cross section of the stand 12 is in the shape of “L” or “T”.

[0024] On the basis of the above-mentioned embodiments, the positioning seat 21 is arranged at the top of the stand 12, and the positioning seat 21 comprises a positioning bracket fixedly arranged at the top of the stand 12, parallel adjusting rods 211 and guide rods 212 arranged on the positioning bracket, the adjusting rods 211 being rotatably connected to the positioning bracket, and symmetric screw structures arranged on the rod bodies of the adjusting rods 211. The guide rods 212 are arranged in parallel on the upper side of the adjusting rods 211. An adjusting handle 213 is fixedly arranged at one end of the adjusting rod 211, and the adjusting handle 213 is a hand wheel.

[0025] The positioning frame 22 comprises a positioning frame body 221 and a non-slip pad 222. The positioning frame body 221 is an “L”-shaped frame body, and threaded holes are formed in the frame body corresponding to the adjusting rods 211, and guide holes are formed in the frame body corresponding to the guide rods 212; a horizontal supporting plate is arranged at the bottom of the opposite side of the positioning frame body 221; the two positioning frames 22 are respectively threadedly connected with the adjusting rods 211 and are respectively slidingly connected with the guide rods 212. The non-slip pads 222 are arranged at the opposite sides of the two positioning frame bodies 221.

[0026] Through the structure of the present solution, when the prefabricated component needs to be detected, the prefabricated component is placed between the two positioning frames 22, and then the adjusting handle 213 is rotated to adjust the distance between the two positioning frames 22, so that the supporting plate of the positioning frame 22 supports the lower end surface of the prefabricated component, and the positioning frame 22 clamps the prefabricated component inside. The movement form of the two positioning frames 22 moving towards each other at the same time can ensure that the prefabricated component is clamped and positioned at the same time, which is convenient for the subsequent detection mechanism 3 to detect.

[0027] On the basis of the above-mentioned embodiments, referring to Figure 2 and Figure 4 , the detection seat 31 comprises a detection frame 311, and the detection frame 311 is a horizontally arranged frame body. A detection handle 313 is arranged at each end of the detection frame 311, and the detection handle 313 is a horizontally arranged handle rod structure. A sliding groove 312 is formed near one of the detection handles 313, and the sliding groove 312 is an “H”-shaped through groove. The sliding groove 312 and the two vertical frames 12 are vertically slidingly connected. The detection assembly is arranged between the sliding groove 312 and the detection handle 313.

[0028] A detection hole 314 is further formed in the detection frame 311, and the detection hole 314 is a through hole penetrating through the detection frame 311. A plurality of detection holes 314 are formed, and the diameters and positions of the detection holes 314 correspond to the embedded steel bars on the prefabricated component to be detected. During detection, the steel bars of the prefabricated component can pass through the detection holes 314. One detection piece 32 is arranged on one side of each detection hole 314.

[0029] In combination with the detection piece 32 and the detection hole 314, the present detection equipment can not only detect the positioning holes on the prefabricated component, but also detect the embedded steel bars thereon. The specific detection method will be described in detail below.

[0030] On the basis of the above-mentioned embodiments, the detection piece 32 comprises a sleeved first detection plate 321 and a second detection plate 322. The bottom of the first detection plate 321 is connected with the detection frame 311; the second detection plate 322 is sleeved in the first detection plate 321 and is slidingly connected with the first detection plate 321; and a damping piece is arranged at the connection position of the first detection plate 321 and the second detection plate 322. The damping piece only needs to satisfy the condition that it can provide the second detection plate 322 with a damping force that can overcome the weight of the second detection plate 322, and a pad body made of elastic material can be used as the damping piece. Through the arrangement of the damping piece, the second detection plate 322 can be stably maintained at its own position without external force, so as to facilitate the subsequent measurement of the total height of the first detection plate 321 and the second detection plate 322.

[0031] On the basis of the above-mentioned embodiments, considering that both the positioning hole on the prefabricated component and the steel bar are cylindrical, the first detection plate 321 and the second detection plate 322 are both arranged as arc-shaped plates.

[0032] On the basis of the above-mentioned embodiments, the detection piece 32 further comprises a sliding block 324 fixedly arranged at one side of the bottom end of the second detection plate 322. The detection frame 311 is provided with a sliding groove corresponding to the sliding block 324, and one end of the sliding groove is in communication with the detection hole 314; the second detection plate 322 is slidingly connected with the detection frame 311 through the sliding block 324, and the second detection plate 322 can move towards or away from the central axis direction of the corresponding detection hole 314.

[0033] Through this structure, when the positioning hole is detected, the detection piece 32 can be pulled towards the inside of the detection hole 314, so that the detection piece 32 can be more easily inserted into the positioning hole of the prefabricated component. When the steel bar is detected, because the detection piece 32 is slidable, it can be pushed away by the steel bar, without affecting the use of the detection hole 314.

[0034] On the basis of the above-mentioned embodiments, a reset piece such as a spring can be arranged inside the sliding groove of the sliding block 324 and the detection frame 311. In the natural state, the reset piece pushes the sliding block 342 towards the direction of the detection hole 314, and when the steel bar is detected, the steel bar presses the detection piece 32, the sliding block 342 slides, and the reset piece is compressed.

[0035] On the basis of the above-mentioned embodiments, the detection piece 32 further comprises a reference piece 324 fixedly arranged on the upper part of the plate body of the second detection plate 322, and the reference piece 324 is an arc-shaped rod-shaped body. The distance between the reference piece 324 and the top of the second detection plate 322 is equal to the thickness of the detection seat 31. The reference piece 324 is used as a comparison for the thickness of the detection seat 31 when the steel bar is detected.

[0036] Unlike the positioning hole testing method, this testing equipment detects the length of reinforcing bars. After the positioning hole testing is completed, the testing seat 31 is slid downwards from the support mechanism 1 until it is removed. The side of the precast component with reinforcing bars to be tested is connected to the positioning mechanism 2, and the precast component is fixed with the positioning frame 22. Then, the testing seat 31 is flipped over, and the slide groove 312 and the upright frame 12 are inserted. The testing seat 31 is then pushed upwards until it is in contact with the side of the precast component with reinforcing bars.

[0037] At this point, the reinforcing bar can pass through the inspection hole 314. By observing the end of the reinforcing bar, the difference in length between the exposed part of the reinforcing bar and the inspection piece 32 can be easily observed. It should be noted here that because the inspection seat 31 is flipped during reinforcing bar inspection, the distance error caused by the thickness of the inspection seat 31 itself needs to be taken into account. Therefore, the reference piece 324 is set up to allow the staff to confirm the distance position to be observed considering the thickness of the inspection seat 31 itself.

[0038] Based on the above implementation scheme, the detection component 32 also includes a limiting component 323, which is linked with the second detection plate 322 to limit the position of the second detection plate 322. The limiting component 323 serves as an auxiliary structure for positioning the second detection plate 322, further ensuring the stability of the position of the second detection plate 322.

[0039] The limiting component 323 can take various forms, as long as it can stabilize the position of the second detection plate 322. A common example is a locking nut, which can also be used as an implementation of the limiting component 323 in this solution. Another different implementation of the limiting component 323 will be presented later.

[0040] Based on the aforementioned solution, the limiting component 323 includes a winding wheel 3231, a cable 3232, and a first locking component 325. A winding wheel cavity 3241 is formed on the slider 324, and the winding wheel 3231 is rotatably disposed within the winding wheel cavity 3241. One end of the cable 3232 is fixedly connected to the winding wheel 3231, and the other end is fixedly connected to the second detection plate 322. A cable channel is formed inside the first detection plate 321 corresponding to the cable 3232, and the cable 3232 is located within the cable channel. The cable 3232 can be wound around the winding wheel 3231. When the cable 3232 is located within the cable channel, it provides upward support to the second detection plate 322. The first locking component 325 is linked with the winding wheel 3231 and can lock the winding wheel 3231.

[0041] With this structure, when the detection element 32 is compressed, that is, when the second detection plate 322 is pushed into the first detection plate 321 by an external force, the second detection plate 322 simultaneously pushes the cable 3232 towards the reel 3231. Driven by the cable 3232, the reel 3231 rotates, winding the cable 3232, thereby achieving the retrieval of the cable 3232. After the first locking assembly 325 locks the reel 3231, because the reel 3231 cannot rotate, the cable 3232 remains unchanged, providing support for the second detection plate 322.

[0042] Once the first locking component 325 releases the lock on the reel 3231, the second detection plate 322 can resume its movement.

[0043] In this design, the cable 3232 should be able to wrap around the reel 3231 and provide support for the second detection plate 322 when located inside the cable channel. The cable 3232 can also take various different forms.

[0044] Based on the above implementation scheme, this solution provides a structural form for the cable 3232. The cable 3232 of this solution includes an inner core and an outer shell assembly. The inner core is made of a flexible material and is a deformable wire. The outer shell assembly includes multiple cylindrical cable shells, each with a hollow interior that fits into the inner core. The cable shells can be made of plastic. With this structure, because the cable shells are not connected, it does not affect the cable 3232's wrapping around the reel 3231. When the cable 3232 is pushed into the cable channel, the inner diameter of the cable channel corresponds to the outer diameter of the cable shells. At this time, the cable shells form a stacked distribution, creating an approximately rod-shaped support structure within the cable channel, thereby supporting the second detection plate 322.

[0045] Based on the above implementation scheme, a coil spring 3233 is provided at the bottom of the coil wheel 3231, and the coil spring 3233 is used as an auxiliary power for the coil wheel 3231 to reset.

[0046] Based on the above implementation scheme, the first locking component 325 of this scheme is a ratchet and pawl combination. The ratchet and the winding wheel 3231 in the first locking component 325 are coaxially and fixedly connected, and a pawl corresponding to the ratchet is provided on the periphery of the ratchet. When the second detection plate 322 is pressed down, the second detection plate 322 can push the cable 3232 to rotate the winding wheel 3231. At this time, the pawl does not limit the ratchet. When the winding wheel 3231 rotates in the opposite direction, the pawl limits the ratchet. The ratchet and pawl combination 3251 can adopt the existing structure, and its specific structure will not be described in detail.

[0047] To unlock the ratchet of the first locking assembly 325, a rotating ring 326 is provided above the first locking assembly 325, and the rotating ring 326 is rotatably connected to the slider 324. A lever 3261 corresponding to the pawl is provided at the lower part of the rotating ring 326. When the rotating ring 326 is rotated, the lever 3261 can move the pawl, releasing the lock on the ratchet. The rotation of the rotating ring 326 is manually operated.

[0048] Based on the above implementation scheme, this scheme also includes a second locking component 327, which is a compression locking assembly. The compression force generated by the detection seat 31 on the end face of the precast component when it contacts the second locking component 327 is used to lock the roller 3231.

[0049] The second locking assembly 327 includes a pressing block 3271, which is vertically slidably connected to a slider 324. The upper surface of the pressing block 3271 is located above the upper surface of the detection seat 31. A pressing pad supported by an elastic material is provided at the lower part of the pressing block 3271.

[0050] When the detection seat 31 moves up to contact the end face of the precast component, the end face of the precast component applies downward pressure to the extrusion block 3271, thereby causing the extrusion block 3271 to apply pressure to the roller 3231, making it difficult for the roller 3231 to rotate.

[0051] Based on the above implementation scheme, the ratchet of the first locking assembly 325 has a circular hole in the middle, and a locking block is provided on the upper surface of the circular hole. The outer diameter of the pressing pad at the lower end of the pressing block 3271 is slightly larger than the locking range formed by the pressing block. That is, when the pressing block 3271 is pressed down, the upper end surface of the periphery of the pressing pad is locked under the locking block in the circular hole in the middle of the ratchet. Even if the detection seat 31 is disengaged from the prefabricated component, the pressing pad maintains downward pressure on the winding wheel 3231.

[0052] Based on the above implementation scheme, and considering the ease of unlocking the compression block 3271, the unlocking of the compression block 3271 and the rotation of the rotating ring 326 are integrated. That is, when the rotating ring 326 rotates, the first locking component 325 and the second locking component 327 can be unlocked simultaneously. The implementation method is as follows: A pressure rod 3272 is provided on one side of the extrusion block 3271, and an unlocking plate 3262 is provided inside the rotating ring 326 corresponding to the pressure rod 3272. The unlocking plate 3262 can rotate with the rotating ring 326. The contact points between the extrusion rod 3272 and the unlocking plate 3262 are both inclined structures.

[0053] When the pressing block 3271 is pressed down, the pressing rod 3272 and the inclined surface of the unlocking plate 3262 come into contact. When the rotating ring 326 is rotated, in addition to the lever 3261 moving the pawl to contact the locking of the first locking assembly 325, the unlocking plate 3262 pushes the pressing rod 3272 to move the pressing block 3271 upward, thereby causing the pressing pad to deform and disengage from the limit of the latch on the ratchet, thereby releasing the pressure on the roller 3231.
