Description

Technical Field

[0001] This invention belongs to the field of grinding technology, and in particular relates to a grinding device and method for the bending area of ​​irregular steel templates. Background Technology

[0002] When constructing a cross-sea bridge, the construction window at the offshore site is short, and the environmental controllability is low. Therefore, to ensure good processing quality and precision for the piers, those skilled in the art typically choose prefabrication technology. During pier prefabrication, workers first tie the reinforcing cage and insert it into steel formwork, followed by concrete pouring, thus obtaining reliable and high-precision prefabricated pier components.

[0003] To meet the mechanical and functional requirements of practical applications, precast pier components typically come in various shapes. Correspondingly, the steel formwork used in the precast pier process is generally divided into two types: ordinary steel formwork and irregular steel formwork (irregular steel formwork refers to steel formwork with bent parts at the edges or specific locations of the main body of the steel formwork, and the bending area formed between the bent parts and the main body of the steel formwork meets the special shaping requirements of the precast pier components). This allows workers to use the formwork according to the shape requirements of the precast pier components.

[0004] However, due to the limited operating space within the bending area of ​​irregularly shaped steel formwork, and the varying angles formed between the bending parts and the main body of the formwork on different shapes, the difficulty of grinding the bending area increases significantly when reusing irregularly shaped steel formwork. Traditional grinding equipment cannot grind both the main body of the steel formwork and the bending parts in the bending area in one go, nor can it adapt well to the different angles between the main body of the steel formwork and the bending parts. Therefore, after grinding, rust, release agent, or concrete residue is easily found inside the bending area, which not only affects the overall construction efficiency but also leads to casting defects on subsequent precast pier components due to residue.

[0026] Step S2: Drive the connecting seat to slide in the direction of the bending part, and drive the bearing plate to descend so that the bending grinding disc contacts the bending part and the main grinding disc contacts the main body of the steel template.

[0027] Step S3: Start the grinding drive assembly to drive the main bearing seat and the bending bearing seat to perform linear reciprocating motion along the attitude adjustment axis, so that the main grinding disc and the bending grinding disc can grind the bending area, and the single stroke of the linear reciprocating motion is greater than the sum of the lengths of the main grinding disc and the bending grinding disc along the attitude adjustment axis.

[0029] Compared with existing technologies, the grinding device and method for the bending area of ​​irregular steel templates described in this invention have the following advantages:

[0030] This invention provides a grinding device and method for the bending area of ​​irregularly shaped steel formwork. The device's support plate is capable of lifting and lowering, and the connecting seat is capable of sliding, thus facilitating the entry of the main grinding unit and the bending grinding unit into the bending area. Furthermore, the device allows the bending grinding unit to rotate according to the inclination of the bending section via a posture adjustment shaft. Therefore, when grinding the bending area of ​​the irregularly shaped steel formwork, the main grinding disc and the bending grinding disc respectively contact the steel formwork body and the bending section, adapting to different angles between the bending section and the steel formwork body. This allows for grinding of both the steel formwork body and the bending section in a single operation, thereby improving the grinding efficiency and quality of the bending area of ​​the irregularly shaped steel formwork. Furthermore, this device is equipped with floating connection components on both the main support and the bending support. Therefore, when the main grinding disc and the bending grinding disc are driven to contact the main body of the steel formwork and the bending part respectively, the floating connection components enable the grinding disc and the support to move relative to each other. This further improves the adaptability of this device to different angles between the bending part and the main body of the steel formwork, and ensures that the grinding disc contacts the junction area between the bending part and the main body of the steel formwork during the grinding process, thereby avoiding dead corners in the bending area of ​​the irregular steel formwork during the grinding process.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] A grinding device for the bending area of ​​irregular steel formwork is used to simultaneously grind the main body of the steel formwork with included angles and the bending part in the bending area of ​​the irregular steel formwork, thereby improving the grinding efficiency and grinding quality of the bending area of ​​the irregular steel formwork.

[0047] Specifically, the grinding device for the bent area of ​​the irregular steel formwork in this embodiment includes: an assembly unit, a support plate 4, a bending grinding unit, and a main grinding unit. The bending grinding unit and the main grinding unit are used to grind the bent portion of the irregular steel formwork and the main body of the steel formwork, respectively. The assembly unit is used to assemble this device with the wall-climbing robot 1, and during the grinding process, it drives other components in the device to move closer to or away from the bent portion. The support plate 4 provides a mounting base for the bending grinding unit and the main grinding unit, and during the grinding process, it drives the bending grinding unit and the main grinding unit to move closer to or away from the main body of the steel formwork.

[0048] like Figure 2 and Figure 3As shown, the assembly unit includes an assembly plate 2 and a connecting seat. The connecting seat is slidably mounted on the assembly plate 2, and a support plate 4 is vertically mounted on the connecting seat, with the support plate 4 parallel to the assembly plate 2. Figure 1 As shown, during use, the assembly plate 2 is detachably mounted on the wall-climbing robot 1 (the detachable connection between the assembly plate 2 and the wall-climbing robot 1 can be achieved using bolt connections, a common technique in the prior art, or by pre-setting clamps or grippers on the wall-climbing robot 1 to mount the assembly plate 2). When grinding irregularly shaped steel templates, the wall-climbing robot 1 will move this device along the steel template body. When the device moves near the bending area, the sliding of the connecting seat and the lifting of the bearing plate 4 allow the bending grinding unit and the main grinding unit to enter the bending area, thus enabling subsequent grinding work on the bending area within a limited operating space.

[0049] Optionally, the connecting base may include a first connecting plate 31 and a second connecting plate 32, wherein the second connecting plate 32 is disposed on one side of the first connecting plate 31, the second connecting plate 32 is perpendicular to the first connecting plate 31, and the first connecting plate 31 is parallel to the assembly plate 2. During design and manufacturing, the operator should adjust the actual dimensions of the second connecting plate 32 according to the specifications of the wall-climbing robot 1, ensuring that the distance from the bottom of the second connecting plate 32 to the bottom surface of the first connecting plate 31 is not greater than the overall height of the wall-climbing robot 1, so as to avoid interference from the connecting base during the movement of the wall-climbing robot 1.

[0050] To facilitate the sliding of the connecting seat, this embodiment includes a guide rail 21 on the assembly plate 2, and a guide slider 22 on the guide rail 21. During assembly, the first connecting plate 31 can be detachably installed onto the guide slider 22 using bolts. In use, the sliding of the guide slider 22 along the guide rail 21 moves the connecting seat. It should be noted that since the center of gravity of the device shifts when the connecting seat slides away from the wall-climbing robot 1, a counterweight 23 should be provided on the side of the assembly plate 2 away from the connecting seat to ensure good stability of the wall-climbing robot 1 during grinding operations. This counterweight 23 helps to balance the center of gravity.

[0051] To achieve the lifting and lowering of the support plate 4, this embodiment may provide a mounting base 311 on the first connecting plate 31, and a lifting electric cylinder 312 on the mounting base 311. Correspondingly, a guide post 42 should be provided on the side wall of the support plate 4 near the second connecting plate 32, and a guide cutout 321 for accommodating the guide post 42 should be provided on the second connecting plate 32. A detachable limiting plate 421 should also be provided at the end of the guide post 42 away from the support plate 4. During assembly, the operator should first insert the guide post 42 into the guide cutout 321, and then install the limiting plate 421 on the guide post 42, so that the limiting plate 421 and the support plate 4 are located on both sides of the second connecting plate 32, respectively. Then, the connection between the end of the telescopic rod of the lifting electric cylinder 312 and the support plate 4 is achieved by bolt connection. At this time, the cooperation between the limiting plate 421 and the bearing plate 4 can prevent the guide post 42 from disengaging from the guide cutout 321, and the cooperation between the guide cutout 321 and the guide post 42 can guide and constrain the lifting action of the bearing plate 4. Therefore, when the lifting electric cylinder 312 drives its telescopic rod to perform telescopic action, the bearing plate 4 will perform a stable and reliable lifting action.

[0052] In practical applications, the angles formed between the bent parts and the main body of different shaped steel templates vary. Therefore, to adapt to different angle conditions and ensure that the bending and grinding unit and the main body grinding unit can perform high-quality grinding on the bent parts and the main body of the steel template, this embodiment also provides a posture adjustment shaft 41 parallel to the bearing plate 4 on the side away from the connecting seat. The posture adjustment shaft 41 should be perpendicular to the sliding direction of the connecting seat. During use, the posture adjustment shaft not only guides the grinding actions of the bending and grinding unit and the main body grinding unit, but also drives the bending and grinding unit to rotate according to the angle between the bent parts and the main body of the steel template, thereby meeting different working requirements.

[0053] Optionally, to drive the attitude adjustment shaft 41 to rotate, a drive rod 412 perpendicular to the attitude adjustment shaft 41 may be provided on the attitude adjustment shaft 41, and an electric telescopic rod 43 perpendicular to the attitude adjustment shaft 41 should also be provided on the support plate 4. During assembly, one end of the electric telescopic rod should be hinged to a pre-set hinge seat on the support plate 4, and the other end should be hinged to the drive rod 412. When it is necessary to adjust the attitude of the bending and grinding unit by rotating the attitude adjustment shaft 41, the electric telescopic rod 43 can be driven to extend and retract, so that the attitude adjustment shaft 41 rotates in accordance with the extension and retraction of the electric telescopic rod 43. For example, when the angle between the bent part and the steel formwork body is large, the electric telescopic rod 43 can be driven to extend, so that the end of the drive rod 412 away from the attitude adjustment shaft 41 rotates away from the connecting seat. When the angle between the bent part and the steel formwork body is small, the electric telescopic rod 43 can be driven to shorten, so that the end of the drive rod 412 away from the attitude adjustment shaft 41 rotates towards the connecting seat.

[0054] Figure 4 and Figure 5 The diagram shows the structure of the bending and grinding unit in this embodiment. As shown, the bending and grinding unit includes a bending support seat and a detection plate 54. The bending support seat is slidably mounted on the attitude adjustment shaft 41, and rotates synchronously with the attitude adjustment shaft 41 when it rotates. The bending support seat has two first floating connection components, each with a detachable bending and grinding disc 61, and the bending and grinding discs 61 on the two first floating connection components are parallel. The detection plate 54 is mounted on the bending support seat, parallel to the bending and grinding discs 61, and has an attitude detection module for determining the relative attitude between the bending and grinding unit and the bent portion of the irregular steel template. In operation, the relative position between the detection plate 54 and the bent portion of the irregular steel template is first determined by the attitude detection module. Based on the determination result, the attitude adjustment shaft 41 is rotated to make the detection plate 54 and the bent portion 102 parallel to each other. Since the detection plate 54 is parallel to the bending grinding disc 61, after the attitude adjustment is completed, the bending grinding disc 61 will also be parallel to the bent portion. Next, the bending grinding disc 61 can be brought into contact with the bent portion by sliding the connecting seat and raising and lowering the bearing plate 4, so that when the device starts grinding, the bent portion on the irregular steel template can be ground by the bending grinding disc 61 to remove the attached substances on the bent portion.

[0055] Optionally, to ensure that the bending support seat rotates synchronously with the attitude adjustment shaft 41, the bending support seat may be provided with a mounting hole 55 for accommodating the attitude adjustment shaft 41, and a limiting strip 551 is provided inside the mounting hole 55. Correspondingly, the side wall of the attitude adjustment shaft 41 should be provided with a limiting groove 411 for accommodating the limiting strip 551, and the length direction of the limiting groove 411 should be parallel to the attitude adjustment shaft 41. When the attitude adjustment shaft 41 rotates, the cooperation between the limiting groove 411 and the limiting strip 551 will transmit the torque on the attitude adjustment shaft 41 to the bending support seat, thereby enabling the bending support seat and the attitude adjustment shaft 41 to rotate synchronously. In addition, since the length direction of the limiting groove 411 should be parallel to the attitude adjustment axis 41, when the bending and grinding unit reciprocates along the attitude adjustment axis 41 due to the grinding action, the limiting strip 551 can also slide inside the limiting groove 411, thereby avoiding motion interference to the grinding action of the bending and grinding unit.

[0056] Figure 6 The diagram shows the structure of the main grinding unit in this embodiment. The main grinding unit includes a main support seat 7 and a grinding drive assembly. The main support seat 7 is rotatably mounted on a bent support seat and is located between two first floating connection assemblies. A second floating connection assembly is provided on the main support seat 7, and a detachable main grinding disc 81 is provided on the second floating connection assembly, with the main grinding disc 81 parallel to the support plate 4. The grinding drive assembly is located on the support plate 4. During grinding, the grinding drive assembly drives the main support seat 7 and the bent support seat to reciprocate linearly along the attitude adjustment axis 41, causing relative friction between the main grinding disc 81 and the bent grinding disc 61 and the steel template, thereby removing the deposits on the steel template.

[0057] For example, the grinding drive assembly in this embodiment may include a linear motor 91 and a connecting rod assembly 92. The connecting rod assembly 92 serves as a transmission connection structure between the linear motor 91 and the main support 7. One end of the connecting rod assembly 92 should be detachably connected to the motion slider of the linear motor 91, and the other end of the connecting rod assembly 92 should be detachably connected to the main support 7. When the linear motor 91 is started, the motion slider will reciprocate linearly along the track. At this time, the connecting rod assembly 92 can transfer the kinetic energy of the motion slider to the main support 7, thereby driving the main support 7 and the bending support to reciprocate linearly along the attitude adjustment shaft 41.

[0058] Optionally, to achieve the assembly between the main support 7 and the bending support, and to ensure that the bending support can follow the main support 7 in linear reciprocating motion along the attitude adjustment shaft 41 driven by the grinding drive assembly, the bending support may include a first limiting segment 51, a connecting segment 52, and a second limiting segment 53 connected in sequence. The main support 7 may be provided with a mounting hole 71 for accommodating the connecting segment 52. The outer diameters of both the first limiting segment 51 and the second limiting segment 53 should be larger than the inner diameter of the mounting hole 71, and the distance between the first limiting segment 51 and the second limiting segment 53 should be equal to the axial length of the mounting hole 71. Since the main support 7 and the grinding drive assembly on the support plate 4 have a transmission connection, when the bending support rotates with the attitude adjustment shaft 41, the transmission connection between the main support 7 and the grinding drive assembly will restrict the rotation of the main support 7. At this time, relative rotation will occur between the connecting segment 52 and the mounting hole 71, preventing the presence of the main support 7 from interfering with the attitude adjustment of the bending support. When the grinding drive assembly drives the main support seat 7 to reciprocate linearly along the attitude adjustment shaft 41, since the outer diameters of the first limiting segment 51 and the second limiting segment 53 are both larger than the inner diameter of the mounting hole 71, and the distance between the first limiting segment 51 and the second limiting segment 53 is equal to the axial length of the mounting hole 71, the reciprocating motion of the main support seat 7 will be transmitted to the bending support seat through the first limiting segment 51 and the second limiting segment 53, thereby causing the bending support seat to move along with the main support seat 7.

[0059] It should be noted that, to facilitate the assembly of the main support 7 and the bending support, the main support 7 can be manufactured as a modular assembly structure, or a detachable connection structure can be provided between the first limiting section 51, the connecting section 52, and the second limiting section 53, thereby reducing the assembly difficulty of the main support 7 and the bending support. Furthermore, a rotating connection structure, such as a bearing, should be provided inside the mounting hole 71 to reduce the rotational frictional resistance between the main support 7 and the bending support, and improve the smoothness of the bending grinding unit during posture adjustment.

[0060] Figure 7 This is a schematic diagram of the grinding device for the bent area of ​​irregular steel formwork in use (assembly unit related structures are hidden). As shown in the figure, during actual operation, the main grinding disc 81 and the bending grinding disc 61 will contact the main body 101 of the steel formwork and the bent portion 102 of the bent area of ​​the irregular steel formwork, respectively. However, when the angle between the main body 101 of the steel formwork and the bent portion 102 changes, adjusting the posture of the bending grinding unit alone may cause misalignment between the main grinding disc 81 and the bending grinding disc 61, resulting in a dead zone in the interface between the bent portion 102 and the main body 101 of the steel formwork.

[0061] To address this issue, this embodiment utilizes a first floating connection assembly to enable relative movement between the bending grinding disc 61 and the bending support seat, and a second floating connection assembly to enable relative movement between the main grinding disc 81 and the main support seat 7, thereby improving the device's adaptability to different angles between the bending portion 102 and the steel template body 101.

[0062] Specifically, such as Figure 4 As shown, the first floating connection assembly includes a first floating seat 62 and a first spring 63, and the bending grinding disc 61 is detachably mounted on the bottom surface of the first floating seat 62. To facilitate assembly between the first floating connection assembly and the bending bearing seat, the bending bearing seat is provided with two positioning components, and the line connecting the two positioning components is parallel to the attitude adjustment shaft 41. Each positioning component includes two parallel first positioning plates 56, and a first guide rod 561 perpendicular to the attitude adjustment shaft 41 is provided between the two first positioning plates 56 in the same positioning component. A first connecting ear 621 is provided at the top of the first floating seat 62, and a first guide hole for accommodating the first guide rod 561 is provided on the first connecting ear 621, and the first spring 63 is sleeved on the first guide rod 561.

[0063] During assembly, the first connecting ear 621 is slidably disposed between the two first positioning plates 56, and the first spring 63 should be located on the side of the first connecting ear 621 away from the bearing plate 4. Since the first guide rod 561 is perpendicular to the attitude adjustment shaft 41, the presence of the first floating connection assembly will not affect the normal grinding operation of the bending grinding disc 61. When the edge of the bending grinding disc 61 contacts the steel template body 101 during the descent of the bearing plate 4, the pushing action of the steel template body 101 on the edge of the bending grinding disc 61 will cause the first floating seat 62 to slide along the first guide rod 561, so that the edge of the bending grinding disc 61 can contact the junction area between the bending part 102 and the steel template body 101, avoiding grinding dead corners in the junction area during grinding. At the same time, the sliding of the first floating seat 62 will compress the first spring 63. The elastic force generated by the compression of the first spring 63 can improve the contact effect between the edge of the bending grinding disc 61 and the junction area, ensuring that the junction area obtains good grinding quality.

[0064] Similar to the first floating connection component, such as Figure 6As shown, the second floating connection assembly includes a second floating seat 82 and a second spring 83, and the main grinding disc 81 is detachably mounted on the bottom surface of the second floating seat 82. To facilitate assembly between the second floating connection assembly and the main support seat 7, the main support seat 7 is provided with two parallel second positioning plates 72, and a second guide rod 721 perpendicular to the attitude adjustment shaft 41 is provided between the two second positioning plates 72. The top of the second floating seat 82 is provided with a second connecting ear 821, and the second connecting ear 821 has a second guide hole for accommodating the second guide rod 721, and the second spring 83 is sleeved on the second guide rod 721.

[0065] During assembly, the second connecting ear 821 is slidably disposed between the two second positioning plates 72, and the second spring 83 is located on the side of the second connecting ear 821 closer to the bearing plate 4. Since the second guide rod 721 is also perpendicular to the attitude adjustment pivot 41, the presence of the second floating connection assembly will not affect the normal grinding operation of the main grinding disc 81. When the edge of the main grinding disc 81 contacts the bending part 102 as the connecting seat slides towards the bending part 102, the abutting action of the bending part 102 on the edge of the main grinding disc 81 will cause the second floating seat 82 to slide along the second guide rod 721, so that the edge of the main grinding disc 81 can contact the junction area between the bending part 102 and the steel template body 101, avoiding grinding dead corners in the junction area during grinding. At the same time, the sliding of the second floating seat 82 will compress the second spring 83. The elastic force generated by the compression of the second spring 83 can improve the contact effect between the edge of the main grinding disc 81 and the junction area, ensuring that the junction area obtains good grinding quality.

[0066] As an optional implementation of this embodiment, to prevent the bending and grinding unit from interfering with the main grinding unit as the posture adjustment shaft 41 rotates, the detection plate 54 may also be provided with a clearance cut 541 for avoiding the main support seat 7. In addition, to facilitate the installation of the posture detection module, the detection plate 54 may also be provided with a group of detection holes for installing the posture detection module.

[0067] As an example and not a limitation, the attitude detection module in this embodiment may include: a first distance sensor 542, a second distance sensor 543, and a third distance sensor 544. Correspondingly, the detection hole group should include: a first detection hole for accommodating the first distance sensor 542, a second detection hole for accommodating the second distance sensor 543, and a third detection hole for accommodating the third distance sensor 544. The line connecting the first and second detection holes should be parallel to the attitude adjustment shaft 41, and the line connecting the third and first detection holes should be perpendicular to the attitude adjustment shaft 41. In use, since the line connecting the first and second detection holes is parallel to the attitude adjustment shaft 41, when the distance information collected by the first distance sensor 542 and the second distance sensor 543 is the same, it can be proven that the attitude adjustment shaft 41 is parallel to the junction area formed by the bent portion and the steel template body. Meanwhile, since the line connecting the third and first detection holes is perpendicular to the attitude adjustment axis 41, when the distance information collected by the first distance sensor 542, the second distance sensor 543, and the third distance sensor 544 is the same, it can be proven that the plane where the attitude detection module is located (i.e., the detection plate 54) is parallel to the bent part of the irregular steel template. In this way, the operator can use the information collected by the above-mentioned distance sensors to determine whether the attitude of the device relative to the bent area meets the grinding requirements and make corresponding adjustments.

[0068] Based on the above, this embodiment also provides a method for grinding the bending area of ​​irregular steel formwork, which is implemented using the aforementioned grinding device for the bending area of ​​irregular steel formwork.

[0069] Figure 8 The flowchart for the grinding process of the bent area of ​​irregular steel formwork is shown in the figure. The specific steps of the grinding process of the bent area of ​​irregular steel formwork include:

[0070] Step S1: After the grinding and processing device moves along the main body 101 of the steel template to the bending area, the relative position of the detection plate 54 and the bending part 102 is determined by the posture detection module, and the detection plate 54 and the bending part 102 are made parallel by rotating the posture adjustment shaft 41.

[0071] It should be noted that when the attitude detection module uses the distance sensor mentioned above, the position of the attitude adjustment shaft 41 should be determined first by the first distance sensor 542 and the second distance sensor 543, and then the relative position of the detection plate 54 and the bent part 102 should be determined by the first distance sensor 542, the second distance sensor 543 and the third distance sensor 544, so as to avoid the attitude adjustment of the detection plate 54 from deviating from the actual situation.

[0072] Step S2: Drive the connecting seat to slide in the direction of the bending part 102, and drive the bearing plate 4 to descend so that the bending grinding disc 61 contacts the bending part 102, and the main grinding disc 81 contacts the steel template body 101.

[0073] It should be noted that during the process of bringing the bending grinding disc 61 into contact with the bending part 102 and the main grinding disc 81 into contact with the steel template body 101, common equipment such as pressure sensors can be used to detect the contact pressure between the bending grinding disc 61 and the main grinding disc 81 and the irregular steel template, so as to avoid causing undue damage to the steel template during the grinding process.

[0074] Step S3: Start the grinding drive assembly to drive the main body support 7 and the bending support to perform linear reciprocating motion along the attitude adjustment axis 41, so that the main grinding disc 81 and the bending grinding disc 61 can grind the bending area, and the single stroke of the linear reciprocating motion is greater than the sum of the lengths of the main grinding disc 81 and the bending grinding disc 61 along the attitude adjustment axis 41.

[0075] It should be noted that when the main bearing seat 7 and the bending bearing seat are driven to perform linear reciprocating motion along the attitude adjustment axis 41, the single stroke of the linear reciprocating motion is greater than the sum of the lengths of the main grinding disc 81 and the bending grinding disc 61 along the attitude adjustment axis 41. This can cause the areas traversed by the main grinding disc 81 and the bending grinding disc 61 to overlap. In this way, it is possible to avoid grinding dead corners in the areas traversed by the main grinding disc 81 and the bending grinding disc 61, and ensure that the bending area of ​​the irregular steel formwork achieves a good effect in removing attachments.

[0076] Step S4: After the grinding process is completed, turn off the grinding drive assembly, and use the sliding of the connecting seat and the lifting of the bearing plate 4 to detach the main grinding disc 81 and the bent grinding disc 61 from the irregular steel template.

[0077] The effects of the above solution are explained below:

[0078] This embodiment provides a grinding device and method for the bending area of ​​irregularly shaped steel formwork. The device allows the main grinding unit and the bending grinding unit to enter the bending area through the movement of the support plate and connecting seat, facilitating grinding operations in confined spaces and improving the grinding efficiency of the bending area of ​​irregularly shaped steel formwork. Furthermore, this device can adjust the posture of the bending grinding components according to the actual angle between the bending part and the main body of the steel formwork, and can achieve relative movement between the grinding disc and the support seat through a floating connection assembly. Therefore, it can meet different practical operational needs and achieve good grinding quality in the bending area of ​​irregularly shaped steel formwork.

[0079] It should be further noted that the wall-climbing robot described in this embodiment is a mature automated mobile work device in the prior art. A linear motor is an existing drive device that directly converts electrical energy into linear motion mechanical energy. A common linear motor typically consists of a sliding block and a track.
