Description

Technical Field

[0001] This application relates to the technical field of rust removal equipment, and in particular to a rust removal device for exposed steel bars embedded in building construction. Background Technology

[0002] Currently, during the construction process, steel bars are often pre-embedded to facilitate subsequent construction. However, the exposed parts of these steel bars are prone to rusting, and the rusting becomes more severe over time, even affecting the performance of the steel bars.

[0003] To remove rust from the surface of reinforcing bars, rust removal equipment is often used. Currently, rust removal equipment mainly uses rust removal liquid, steel brushes, sandblasting, etc., to remove rust from reinforcing bars, and all of them have good rust removal effects.

[0004] Since the pre-embedded steel bars are generally installed vertically, with the lower end embedded in the concrete and the upper end exposed, the steel bars cannot be moved. Therefore, the only way to remove the rust is to put the rust removal equipment on the outside of the steel bars.

[0005] Existing rust removal equipment is often of fixed size, while the steel bars that need to be rusted are of varying lengths. Therefore, when the rust removal equipment is used to remove rust from longer steel bars, the upper part of the steel bar is outside the rust removal range of the equipment. This makes it impossible to remove rust from this part of the steel bar. So, in the end, the rust removal equipment can only be removed manually by holding it by hand or lifting it up. However, using this method will increase the rust removal time and additional labor costs. Summary of the Invention

[0006] This application provides a rust removal device for pre-embedded exposed steel bars in building engineering. The purpose of the device is to enable it to move automatically along the length of the steel bar and perform rust removal operations, which can speed up the rust removal process, reduce the time required for rust removal, and also reduce labor costs.

[0007] The rust removal device for pre-embedded exposed steel bars in building engineering provided in this application adopts the following technical solution:

[0008] A rust removal device for pre-embedded exposed steel bars in building construction includes: a rust removal cylinder with a rust removal hole for accommodating the steel bars extending through one end; a plurality of rust removal units for rust removal are arranged on the inner wall of the rust removal hole; a climbing mechanism is provided at both ends of the rust removal cylinder, the climbing mechanism including a plurality of drive wheels arranged around the rust removal hole along its circumference; a first drive component for driving the drive wheels to rotate is coaxially connected to each drive wheel; the drive wheels are slidably connected to the rust removal cylinder; and a clamping drive assembly is provided on the rust removal cylinder for driving the drive wheels to move toward or away from the rust removal hole.

[0009] By adopting the above technical solution, the rust removal cylinder allows the reinforcing bar to be directly inserted into the rust removal cylinder through a rust removal hole at one end. The reinforcing bar contacts the rust removal unit set on the inner wall of the rust removal hole, and the rust removal unit achieves effective rust removal.

[0010] The climbing mechanism at both ends of the rust removal cylinder includes drive wheels and a clamping drive assembly. Several drive wheels are arranged sequentially along the circumference of the rust removal hole. By setting the clamping drive assembly, the drive wheels can make close contact with the surface of the steel bar, providing the necessary friction to maintain the stability of the rust removal cylinder. This can fix the rust removal device on the steel bar, so that the rust removal device has stable support when performing rust removal operations.

[0011] The climbing mechanism also includes a first driving component, which drives the corresponding driving wheel to rotate. So when several driving wheels rotate synchronously, the rust removal device can be driven to move along the length of the steel bar on the steel bar, which can drive the rust removal device to perform rust removal operations at different positions on the steel bar.

[0012] This structural design allows the rust removal device to be installed on steel bars of different lengths, enabling automatic rust removal operations. This improves rust removal efficiency and operational safety, while also reducing labor costs.

[0013] Optionally, both ends of the rust removal cylinder are provided with a clamping mechanism, the clamping mechanism including a plurality of clamping rods, the plurality of clamping rods being arranged around the rust removal hole along the circumference of the rust removal hole; the length direction of the clamping rods being arranged radially corresponding to the rust removal hole, and a clamping elastic pad being provided at the end of the clamping rods facing the rust removal hole; the clamping rods are all slidably connected to the rust removal cylinder along their own length direction, and the rust removal cylinder is provided with a clamping drive assembly for driving the clamping rods to move along their own length direction.

[0014] By adopting the above technical solution, the clamping mechanism includes a clamping rod and a clamping elastic pad. The clamping rod is arranged radially along the rust removal cylinder, and the clamping rod is controlled to move along its own length direction by the clamping drive assembly.

[0015] The clamping mechanism is designed so that during rust removal operations, several clamping rods move toward the reinforcing bars, causing the clamping elastic pads to press against the reinforcing bars. Through the elastic action of the clamping elastic pads, the rust removal cylinder is firmly fixed to the reinforcing bars.

[0016] The clamping elastic pad provides a buffer mechanism that maintains close contact between the rust removal cylinder and the rebar when the rebar surface is uneven or experiences slight movement, preventing poor rust removal or work interruption caused by rebar vibration or displacement. This structure improves the stability and reliability of rust removal operations and reduces safety risks caused by device loosening.

[0017] Optionally, a drive plate is provided at both ends of the rust removal cylinder, and a drive hole is provided through the drive plate, and the drive hole is coaxially connected with the rust removal hole; the climbing mechanism is provided in one-to-one correspondence with the drive plate, the climbing mechanism is provided on the corresponding drive plate, and the drive plate is detachably connected to the rust removal cylinder.

[0018] By adopting the above technical solution, the drive plate allows the climbing mechanism to be stably installed on the rust removal cylinder. The drive hole on the drive plate is coaxially connected with the rust removal hole, ensuring that the reinforcing bar can be inserted into the rust removal device. The detachable connection between the drive plate and the rust removal cylinder facilitates the replacement of the rust removal cylinder or the drive plate, and facilitates the maintenance of the rust removal device.

[0019] Optionally, the clamping drive assembly includes several guide members, each guide member corresponding to a drive wheel. Each guide member includes a guide seat, the guide seat being radially arranged along the length direction of the drive hole, and one end of the guide seat facing the drive hole being connected to the corresponding drive wheel. The guide seat is slidably connected to the drive plate along its own length direction. The clamping drive assembly also includes a linkage member, which includes a gear ring and several connecting rods. The gear ring is disposed on the drive plate, coaxially arranged with the drive hole, and rotatably connected to the drive plate. Each connecting rod corresponds to a guide seat, and both ends of the connecting rod are rotatably connected to the gear ring and the corresponding guide seat, respectively. The clamping drive assembly also includes a power member, disposed on the drive plate, and used to drive the gear ring to rotate.

[0020] By adopting the above technical solution, the clamping drive assembly includes a guide component, a linkage component, and a power component. The guide seat in the guide component guides the movement of the drive wheel, ensuring that the drive wheel moves towards or away from the drive hole along the length of the guide seat. The gear ring and connecting rod design in the linkage component allows the gear ring to drive all the connecting rods when it rotates. Furthermore, the synchronous movement of several connecting rods drives several guide seats to move along their own length, thus driving the drive wheel. The power component provides power for the rotation of the gear ring. Therefore, through the cooperation of the guide component, linkage component, and power component, the drive wheel can be driven towards the drive hole, allowing it to contact the surface of the reinforcing bar; or it can be driven away from the drive hole, allowing it to separate from the reinforcing bar. This structure enables the synchronous movement of several drive wheels, improving the stability of the entire climbing mechanism.

[0021] Optionally, the drive plate is provided with a plurality of guide grooves, each guide groove corresponding to a guide seat, and the length direction of the guide groove is along the length direction of the corresponding guide seat; a guide block is provided on the guide seat, the guide block is inserted into the corresponding guide groove, and the guide block is slidably connected to the inner wall of the corresponding guide groove along the length direction of the corresponding guide seat.

[0022] By adopting the above technical solution, the opening of the guide groove provides a stable movement path for the guide seat. The guide block and guide groove are interlocked, ensuring the stability and accuracy of the guide seat during movement. Therefore, through the cooperation of the guide groove and guide block, the movement direction of the drive wheel can be guided and limited.

[0023] Optionally, a guide spring is provided in the guide groove. The guide spring is axially arranged along the length direction of the guide groove, and one end of the guide spring is connected to the inner wall of the guide groove, while the other end is connected to the corresponding guide block.

[0024] By adopting the above technical solution, the guide spring is configured in two ways: First, when the drive wheel moves toward the drive hole, the guide spring is compressed, which allows it to provide a stable counterforce and ensure the stability of the drive wheel's movement. Second, when the drive wheel returns to its original position, the guide spring provides a restoring force, ensuring that the drive wheel can quickly enter its correct position.

[0025] Optionally, the power component includes a rack that meshes with the gear ring and is slidably connected to the drive plate along its own length direction. The drive plate is provided with a linear drive source for driving the rack to move along its own length direction.

[0026] By adopting the above technical solution, the rack and linear drive unit can be coordinated to drive the gear ring because the rack meshes with the gear ring.

[0027] Optionally, the outer wall of the rust removal cylinder is provided with a plurality of insertion slots, which are arranged sequentially at intervals along the circumference of the rust removal cylinder, and all of the insertion slots are connected to the rust removal holes; the rust removal cylinder is also provided with a plurality of insertion blocks, which are arranged one-to-one with the insertion slots, and the insertion blocks are inserted into the corresponding insertion slots; the insertion blocks are arranged one-to-one with the rust removal units, and the side of the insertion block facing the central axis of the rust removal hole is connected to the corresponding rust removal unit.

[0028] By adopting the above technical solution, the cooperation between the insertion slot and the insertion block allows for the free installation and removal of the insertion block inside the rust removal cylinder. The rust removal unit is installed on the insertion block, facilitating quick installation and removal of the rust removal unit. Therefore, this structural design facilitates the replacement of the rust removal unit and reduces maintenance costs.

[0029] Optionally, the rust removal unit includes a steel brush roller, which is axially arranged along the axial direction of the rust removal cylinder, and is rotatably connected to the corresponding plug-in block. The steel brush roller is coaxially connected to a rust removal drive component for driving the steel brush roller to rotate.

[0030] By adopting the above technical solution, the steel brush roller is arranged axially along the rust removal cylinder and rotatably connected to the plug block, ensuring that the steel brush roller can directly act on the surface of the reinforcing bar. The rust removal drive component provides the necessary power to the steel brush roller, enabling it to perform rust removal operations at an appropriate speed and force. Therefore, driven by the rust removal drive component, the steel brush roller can effectively perform physical friction on the surface of the reinforcing bar, thereby achieving the purpose of removing rust.

[0031] Optionally, a mounting plate is provided on one axial side of the rust removal cylinder, and a clearance hole is provided through the mounting plate. The clearance hole is coaxially connected to the rust removal cylinder, and the climbing mechanism is provided on the corresponding mounting plate. The mounting plate is detachably connected to the rust removal cylinder, and a plurality of rust removal driving components are provided on the side of the mounting plate facing the rust removal cylinder. The output shaft of the rust removal driving component is detachably connected to the corresponding steel brush roller.

[0032] By adopting the above technical solution, the presence of clearance holes on the mounting plate ensures that the reinforcing bars can be properly inserted into the rust removal device. The rust removal drive components are all mounted on the mounting plate, and the rust removal cylinder is detachably connected to the mounting plate. Furthermore, the rust removal drive components are also detachably connected to the corresponding steel brush rollers. Therefore, after removing the mounting plate and the rust removal drive components, it is easy to disassemble the connector block and the corresponding steel brush rollers, which facilitates the replacement and installation of the rust removal unit.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. This application provides a climbing mechanism and a clamping mechanism at both ends of the rust removal cylinder, enabling the rust removal cylinder to be installed at any position along the length of the reinforcing bar. Therefore, the rust removal device can perform rust removal operations at any position of the reinforcing bar.

[0035] 2. The climbing mechanism of this application enables the rust removal cylinder to move along the length of the reinforcing bar, which allows the rust removal cylinder to automatically move to the position where rust appears on the reinforcing bar, thus achieving fully automatic rust removal. This makes the rust removal device unaffected by the length of the reinforcing bar, which can improve the applicability of the rust removal device, improve the rust removal efficiency, and reduce labor costs.

[0036] 3. This application facilitates the disassembly and installation of the rust removal unit through the combination of plug-in blocks, plug-in slots, and mounting plates, thus facilitating the maintenance of the rust removal device. Attached Figure Description

[0051] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail below.

[0052] A rust removal device for exposed steel bars embedded in building construction, referring to Figure 1 and Figure 2 The system includes a rust-removing cylinder 1, which is vertically oriented. A rust-removing hole 11 is formed through one end of the cylinder 1, coaxially aligned with the cylinder. Several rust-removing units 2 are evenly spaced along the circumference of the hole 11 on its inner wall. Both ends of the cylinder 1 are equipped with drive plates 3, each with a drive hole 31. A climbing mechanism 4 is also provided on the drive plate 3. A clamping plate 5 is positioned on the side of the drive plate 3 away from the cylinder 1 along its axial direction. The clamping plate 5 is bolted to the corresponding drive plate 3, and has a clamping hole 51. A clamping mechanism 6 is also provided on the clamping plate 5. The rust-removing hole 11, drive hole 31, and clamping hole 51 are coaxially connected.

[0053] Rust removal is achieved through the rust removal cylinder 1. The climbing mechanism 4 can move the rust removal cylinder 1 along the steel bar, allowing it to remove rust at any position along the length of the steel bar. The clamping mechanism 6 increases the stability of the connection between the rust removal cylinder 1 and the steel bar during rust removal.

[0054] Reference Figure 2 and Figure 3 The rust removal unit 2 includes a steel brush roller 21 and a rust removal drive unit 22. The steel brush roller 21 is arranged vertically and located inside the rust removal hole 11. The steel brush roller 21 is rotatably connected to the rust removal cylinder 1, and one end of the steel brush roller 21 is coaxially connected to the output shaft of the rust removal drive unit 22, which is a motor. After the reinforcing bar is inserted into the rust removal hole 11, the rust removal drive unit 22 is activated to rotate the steel brush roller 21, which can brush away the rust on the surface of the reinforcing bar, thus realizing the rust removal operation of the reinforcing bar.

[0055] Reference Figure 2 and Figure 3 The rust removal cylinder 1 is equipped with several quick-change components 12, and each quick-change component 12 is configured in a one-to-one correspondence with the rust removal unit 2.

[0056] Reference Figure 2 and Figure 3The quick-change assembly 12 includes a plug-in block 121. A plurality of plug-in slots 122 are formed on the outer wall of the rust-removing cylinder 1. These slots 122 are evenly spaced along the circumference of the rust-removing cylinder 1, and their depth direction is arranged radially along the corresponding direction of the rust-removing cylinder 1. The plug-in slots 122 communicate with the rust-removing holes 11. The plug-in block 121 and the plug-in slot 122 are arranged in a one-to-one correspondence, and the plug-in block 121 is plugged into the corresponding slot 122. This mating arrangement of the plug-in block 121 and the slot 122 facilitates the installation of the plug-in block 121 onto the rust-removing cylinder 1 and also facilitates the removal of the plug-in block 121 from the rust-removing cylinder 1.

[0057] Reference Figure 2 and Figure 3 The plug-in block 121 is provided in a one-to-one correspondence with the steel brush roller 21. The steel brush roller 21 is located on the side of the corresponding plug-in block 121 facing the central axis of the rust removal hole 11, and the steel brush roller 21 is rotatably connected to the corresponding plug-in block 121. Since the plug-in block 121 is easy to install onto the rust removal cylinder 1 and easy to remove from the rust removal cylinder 1, this facilitates the replacement and maintenance of the steel brush roller 21.

[0058] Reference Figure 2 and Figure 3 A mounting plate 13 is provided at the upper end of the rust removal cylinder 1, and the mounting plate 13 is located between the rust removal cylinder 1 and the corresponding drive plate 3. The mounting plate 13 and the corresponding drive plate 3 are connected by bolts, and the mounting plate 13 and the rust removal cylinder 1 are detachably connected. A clearance hole 131 is provided through the mounting plate 13, and the clearance hole 131, the rust removal hole 11, and the drive hole 31 are coaxially connected. Since the mounting plate 13 and the corresponding drive plate 3 are connected by bolts, and the drive plate 3 and the corresponding clamping plate 5 are connected by bolts, the mounting plate 13, the corresponding drive plate 3, and the corresponding clamping plate 5 can be connected as a whole or disassembled, so it is convenient to replace each component.

[0059] Reference Figure 3 and Figure 4 A plurality of connecting components 15 are provided between the mounting plate 13 and the rust removal cylinder 1, and the plurality of connecting components 15 are arranged sequentially at intervals along the circumference of the clearance hole 131. In this embodiment, two connecting components 15 are provided, and the two connecting components 15 are arranged at intervals along the radial direction of the clearance hole 131, and the clearance hole 131 is located between the two connecting components 15.

[0060] Reference Figure 3 and Figure 4The connecting assembly 15 includes connecting bolts 151. The mounting plate 13 has several through holes 152 on the side facing the rust-removing cylinder 1, and the through holes 152 vertically pass through the mounting plate 13, the corresponding drive plate 3, and the corresponding clamping plate 5 in sequence. The rust-removing cylinder 1 has several locking holes 153 on the side facing the mounting plate 13. The locking holes 153 are threaded holes, and each locking hole 153 corresponds to one of the through holes 152, and the locking holes 153 are coaxially connected to the corresponding through holes 152. The connecting bolts 151 and locking holes 153 are also coaxially inserted into each other, and the inner walls of the connecting bolts 151 and locking holes 153 are connected by threads.

[0061] When the connecting bolts 151 are tightened, the mounting plate 13 and the rust-removing cylinder 1 are locked together. When several connecting bolts 151 are loosened, the connecting bolts 151 are pulled out from the corresponding locking holes 153, at which point the lock between the mounting plate 13 and the rust-removing cylinder 1 is released, and thus the mounting plate 13 and the rust-removing cylinder 1 can be disassembled. Therefore, the connecting assembly 15 enables a detachable connection between the mounting plate 13 and the rust-removing cylinder 1.

[0062] Reference Figure 2 and Figure 3 A sliding assembly 14 is also provided between the mounting plate 13 and the rust removal cylinder 1. The sliding assembly 14 includes several sliding columns 141, which are located between the rust removal cylinder 1 and the mounting plate 13. The sliding columns 141 are arranged axially in the vertical direction. The several sliding columns 141 are arranged around the rust removal hole 11 around the clearance hole 131 in the circumferential direction. The upper end of the sliding column 141 is fixedly connected to the mounting plate 13. Several sliding holes 142 are opened at the end of the rust removal cylinder 1 facing the mounting plate 13. The sliding holes 142 are arranged one-to-one with the sliding columns 141. The lower end of the sliding column 141 is inserted into the corresponding sliding hole 142, and the sliding column 141 is slidably connected to the inner wall of the sliding hole 142 along its own axial direction.

[0063] Therefore, the sliding component 14 is designed so that after the locking between the mounting plate 13 and the rust removal cylinder 1 is released, the mounting plate 13 can slide vertically to open the rust removal cylinder 1.

[0064] Reference Figure 2 and Figure 3Several rust-removing drive components 22 are fixed on the side of the mounting plate 13 facing the rust-removing cylinder 1. A quick-connect assembly 23 is provided between the rust-removing drive component 22 and the corresponding steel brush roller 21. The quick-connect assembly 23 includes a drive rod 231, which is coaxially connected to the output shaft of the rust-removing drive component 22. The upper end of the steel brush roller 21 has a drive groove 232, and the lower end of the drive rod 231 is inserted into the corresponding drive groove 232. When the drive rod 231 is inserted into the corresponding drive groove 232, when the rust-removing drive component 22 drives the drive rod 231 to rotate, the side wall of the drive rod 231 abuts against the side wall of the corresponding drive groove 232, which enables the drive rod 231 to drive the corresponding steel brush roller 21 to rotate, thereby realizing the rust removal operation.

[0065] Specifically, refer to Figure 3 and Figure 5 The shape of the drive groove 232 matches the cross-sectional shape of the drive rod 231. In this embodiment, the cross-section of the drive rod 231 and the shape of the drive groove 232 are rectangular.

[0066] The cooperation between the drive rod 231 and the drive groove 232 ensures that the drive rod 231 can drive the corresponding steel brush roller 21 to rotate, while facilitating the separation of the drive rod 231 from the corresponding steel brush roller 21, thereby realizing the detachable connection between the rust removal drive component 22 and the corresponding steel brush roller 21.

[0067] Reference Figure 2 and Figure 3 With the cooperation of quick-connect component 23 and sliding component 14, after the locking between mounting plate 13 and rust removal cylinder 1 is released, mounting plate 13 can be moved vertically upwards directly. At this time, mounting plate 13 and rust removal cylinder 1 are separated, and rust removal drive component 22 and corresponding steel brush roller 21 are separated simultaneously. This makes it easier to replace and install steel brush roller 21.

[0068] Reference Figure 2 and Figure 6 The drive plate 3 has a first mounting cavity 32, which is connected to the drive hole 31, and the climbing mechanism 4 is set in the corresponding first mounting cavity 32.

[0069] Reference Figure 6 and Figure 7 The climbing mechanism 4 includes a plurality of drive wheels 41, which are evenly spaced around the drive hole 31 along the circumference of the drive hole 31. A first drive component 42 is coaxially connected to the drive wheel 41. The first drive component 42 is a motor, and a clamping drive assembly 43 is also provided on the drive wheel 41.

[0070] After the drive assembly 43 drives the drive wheel 41 to contact the reinforcing bar, the friction between the drive wheel 41 and the reinforcing bar can fix the rust removal device to the reinforcing bar. On this basis, the first drive member 42 drives the drive wheel 41 to rotate, which can drive the rust removal device to move on the reinforcing bar.

[0071] Reference Figure 6 and Figure 7 The abutting drive assembly 43 includes several guide members 431, each guide member 431 is correspondingly arranged with a drive wheel 41. Each guide member 431 includes a guide seat 4311, the guide seat 4311 is arranged radially along the drive hole 31 in the length direction, the side of the guide seat 4311 close to the drive hole 31 in the length direction is connected to the corresponding drive wheel 41, and the guide seat 4311 is slidably connected to the inner wall of the first mounting cavity 32 along its own length direction.

[0072] Reference Figure 6 and Figure 7 The inner wall of the first mounting cavity 32 is provided with a plurality of guide grooves 4312, and the guide grooves 4312 are provided in a one-to-one correspondence with the guide seats 4311. The length direction of the guide grooves 4312 is set along the length direction of the corresponding guide seats 4311. The guide seats 4311 are provided with guide blocks 4313, which are inserted and engaged with the corresponding guide grooves 4312. The guide blocks 4313 are slidably connected to the inner wall of the corresponding guide grooves 4312 along their own length direction.

[0073] By cooperating with the guide groove 4312 and the guide block 4313, the movement of the guide seat 4311 is limited and guided, so that the guide seat 4311 can only move along its own length direction, thus meeting the driving requirements of the drive wheel 41.

[0074] Reference Figure 6 and Figure 7 A guide spring 4314 is also provided inside the guide groove 4312. The guide spring 4314 is axially arranged along the length direction of the corresponding guide seat 4311, and one end of the guide spring 4314 is connected to the inner wall of the guide groove 4312, and the other end is connected to the guide block 4313. The guide spring 4314 can improve the stability of the guide seat 4311 moving along its own length direction.

[0075] Reference Figure 6 and Figure 7The clamping drive assembly 43 also includes a linkage 432, which includes a gear ring 4321 and several connecting rods 4322. The gear ring 4321 is coaxially arranged with the drive hole 31. Several drive wheels 41 and several guide seats 4311 are all arranged inside the gear ring 4321. The gear ring 4321 is rotatably connected to the inner wall of the first mounting cavity 32. The connecting rods 4322 and guide seats 4311 are arranged in a one-to-one correspondence, and one end of the connecting rod 4322 is rotatably connected to the gear ring 4321, and the other end is rotatably connected to the corresponding guide seat 4311.

[0076] The linkage 432 and the guide 431 are configured to work together so that when the gear ring 4321 rotates, the connecting rod 4322 can drive the guide seat 4311 to move along its own length direction, which can drive the drive wheel 41.

[0077] Reference Figure 6 and Figure 7 The clamping drive assembly 43 also includes a power component 433, which includes a rack 4331 and a linear drive source 4332. The rack 4331 meshes with a gear ring 4321, and the rack 4331 slides along its own length direction to the inner wall of the first mounting cavity 32. One end of the rack 4331 in the length direction is connected to the linear drive source 4332, which is a linear motor or a linear push rod.

[0078] When the linear drive source 4332 drives the rack 4331 to move along its own length, the rack 4331 drives the gear ring 4321 to rotate, which satisfies the driving requirements of the gear ring 4321.

[0079] Reference Figure 2 and Figure 8 The clamping plate 5 has a second mounting cavity 52, which is connected to the clamping hole 51, and the clamping mechanism 6 is located in the second mounting cavity 52.

[0080] Reference Figure 2 and Figure 8 The clamping mechanism 6 includes several clamping rods 61, which are arranged around the clamping hole 51 circumferentially. One end of the clamping rod 61 in the length direction faces the central axis of the clamping hole 51, so the length direction of the clamping rod 61 is arranged radially corresponding to the clamping hole 51. A locking groove 64 is provided on the inner wall of the second mounting cavity 52. ​​The clamping rod 61 and the locking groove 64 are arranged in a one-to-one correspondence. The length direction of the locking groove 64 is arranged along the length direction of the clamping rod 61, and one side of the locking groove 64 in the length direction communicates with the clamping hole 51.

[0081] Reference Figure 2 and Figure 8The clamping rod 61 is inserted into the corresponding locking groove 64, and the clamping rod 61 slides along its length to the inner wall of the corresponding locking groove 64. A clamping elastic pad 62 is provided at the end of the clamping rod 61 facing the drive hole 31 along its length.

[0082] Reference Figure 6 and Figure 8 The clamping mechanism 6 also includes a clamping drive assembly 63. The structure of the clamping drive assembly 63 is the same as that of the clamping drive assembly 43. Several connecting rods 4322 in the clamping drive assembly 63 are arranged in a one-to-one correspondence with several clamping rods 61, and the several connecting rods 4322 in the clamping drive assembly 63 are rotatably connected to the corresponding clamping rods 61.

[0083] Reference Figure 8 After the reinforcing bar is inserted into the rust removal hole 11, the clamping drive assembly 63 drives several clamping rods 61 to press against the reinforcing bar. The clamping elastic pads 62 increase the friction between the clamping rods 61 and the reinforcing bar, which increases the stability of the rust removal device and the reinforcing bar. Therefore, reducing the impact of vibration on the rust removal device during operation can reduce the possibility of the rust removal device falling.

[0084] The implementation principle of this application embodiment is as follows: When performing rust removal on reinforcing bars, the reinforcing bars are inserted into the rust removal device. The rust removal device is then activated. First, the climbing mechanism 4 is activated, moving the rust removal device to the corresponding position. Then, the clamping mechanism 6 is activated, fixing the rust removal device. Several rust removal units 2 inside the rust removal cylinder 1 then operate to remove rust from the reinforcing bars. After rust removal is completed, the clamping mechanism 6 is closed, and the climbing mechanism 4 moves the rust removal device to the next part of the reinforcing bar. The clamping mechanism 6 is then restarted to fix the rust removal device, and the several rust removal units 2 are restarted to complete the rust removal of the reinforcing bars. The above operation is repeated until all parts of the reinforcing bars have been rust-removed.

[0085] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
