Description

Technical Field

[0001] This invention relates to the field of concrete construction equipment technology, and in particular to a multi-stage concrete construction device and its construction method. Background Technology

[0002] During construction, concrete floors often require processes such as leveling, vibrating, and finishing. Currently, these processes are generally performed manually. With the advancement of technology, companies have developed separate mechanical equipment for each process, and people still need to manually operate the corresponding equipment to perform the leveling, vibrating, and finishing processes.

[0003] In existing construction processes, manual labor is used in conjunction with corresponding equipment to carry out each step in sequence. However, in multi-step operations, workers need to take different mechanical equipment to carry out each step in sequence, which wastes manpower and reduces the efficiency of construction. Summary of the Invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a multi-process concrete construction device and construction method, which solves the technical problem that in multi-process work, workers need to take different mechanical equipment for construction, resulting in waste of manpower and reduced construction efficiency.

[0009] The vibrating mechanism is fixedly installed above the traveling mechanism, and the vibrating mechanism can be distributed along the longitudinal direction of the traveling mechanism and extend to the first end with a vibrating rod facing downward. The vibrating rod can extend downward into the concrete for vibration.

[0010] The auxiliary working mechanism is located at the first end of the traveling mechanism and is connected to the vibration mechanism. The auxiliary working mechanism can selectively flatten, groove, or stamp the vibrated concrete.

[0011] The finishing mechanism is located in the space below the traveling mechanism, and the finishing mechanism can finish the vibrated concrete.

[0012] Optionally, the walking mechanism includes a walking frame, four swing arm links, and two oppositely arranged walking legs;

[0023] The crossbeam is connected to the telescopic end of the telescopic boom, and hydraulic lifting columns are provided at both ends of the bottom of the crossbeam. The crossbeam and the process conversion assembly are connected by two hydraulic lifting columns.

[0024] The process conversion assembly includes a process conversion frame, a process conversion drive, and a process rotating shaft. The process conversion frame has a gate-shaped structure. The process conversion drive is located on one side of the process conversion frame. The process rotating shaft is located at the bottom opening of the process conversion frame. The two ends of the process rotating shaft are rotatably connected to the bottom ends of the process conversion frame, and one end of the process rotating shaft passes through the process conversion frame and is connected to the process conversion drive.

[0027] The connecting base and the grinding disc are connected by a grinding disc mounting column. The top of the grinding disc mounting column passes through the connecting base and is connected to a grinding disc rotating structure. The grinding disc rotating structure is located between the rectangular frame and the connecting base to drive the grinding disc mounting column to rotate, thereby driving the grinding disc to rotate.

[0028] A steering motor is provided between the connecting chassis and the rectangular frame. A steering gear is provided at the output end of the steering motor. The steering gear meshes with a driven gear. The driven gear is fixedly installed on the rectangular frame. A steering shaft is provided extending downward from the driven gear. The steering shaft rotates relative to the connecting chassis.

[0029] Optionally, it also includes a reaction braking device, which is disposed at the second end of the traveling mechanism. The reaction braking device includes a hanger mounted on one end of the telescopic boom and a push hydraulic cylinder mounted on one end of the connecting chassis. The extended end of the push hydraulic cylinder is hinged to a linkage rod via a pin. The bottom of the hanger has an opening, and the linkage rod passes through the opening and is hinged to an L-shaped transmission rod. The lateral end of the L-shaped transmission rod is hinged to the bottom of the hanger. The bottom of the opening of the hanger is enclosed by an encapsulation plate. A lateral plate is provided at the bottom of the corner of the L-shaped transmission rod, and a hook is provided at the bottom of the lateral plate. The hook can clamp the steel mesh.

[0030] On the other hand, a multi-stage concrete construction method, the method being based on a multi-stage concrete construction device, includes the following steps:

[0031] S1. Concrete is placed onto the steel mesh to be laid using an external concrete placing machine;

[0032] S2. Start the vibration mechanism and use the walking mechanism to drive the vibration mechanism to vibrate the concrete;

[0033] S3. The vibrator moves upward and detaches from the concrete surface to prepare for subsequent construction.

[0034] S4. Start the auxiliary working mechanism to selectively perform leveling, grooving, embossing, or finishing work on the concrete surface.

[0035] The beneficial effects of this invention are as follows: This invention provides a multi-process concrete construction device and method. Through a walking mechanism, the vibration mechanism, auxiliary working mechanism, and finishing mechanism are flexibly moved on a steel mesh to perform vibration, leveling, grooving, stamping, and finishing processes on the concrete on the steel mesh. Different processes can be operated independently, and one or more processes can be selectively implemented. In other words, this is a multi-functional concrete construction device that integrates automated operations such as concrete leveling, vibration, finishing, grooving, and stamping, achieving a high degree of human-machine collaboration. This not only significantly improves the efficiency of concrete construction operations but also effectively reduces labor costs and the incidence of safety accidents. It is highly adaptable, offering processes such as leveling, troweling, grooving, and stamping, and can flexibly and seamlessly switch between various working modes. Attached Figure Description

[0052] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] See Figures 1-9As shown in the embodiment of the present invention, a multi-stage concrete construction device includes a traveling mechanism 1, a vibration mechanism 2, an auxiliary working mechanism 3, and a finishing mechanism 4. The traveling mechanism 1 is equipped with the vibration mechanism 2, the auxiliary working mechanism 3, and the finishing mechanism 4. The traveling mechanism 1 has traveling legs 13, which can contact or separate from the steel mesh 100. When the traveling legs 13 move in the forward direction, they drive the vibration mechanism 2, the auxiliary working mechanism 3, and the finishing mechanism 4 forward together. The vibration mechanism 2 is partially fixedly installed above the traveling mechanism 1, and the vibration mechanism 2 is distributed along the longitudinal direction of the traveling mechanism 1 and extends to the outside of the first end 101 with a downward-facing vibrating rod 211. The vibrating rod 211 can extend downward into the concrete for vibration. The auxiliary working mechanism 3 is located at the first end 101 of the traveling mechanism 1 and is connected to the vibration mechanism 2. The auxiliary working mechanism 3 can selectively flatten, groove, or emboss the vibrated concrete. The finishing mechanism 4 is located in the space below the traveling mechanism 1, and the finishing mechanism 4 can finish the vibrated concrete.

[0054] Furthermore, the walking mechanism 1 includes a walking frame 11, four swing arm links 12, and two opposing walking legs 13. The walking frame 11 includes a rectangular frame 111 and connecting legs 112 fixedly disposed at the four corners of the bottom end face of the rectangular frame 111. The bottom ends of the four connecting legs 112 are all hinged to one end of the swing arm link 12. The other end of one swing arm link 12 is hinged to a top connecting end 131 of one walking leg 13. The other end of another swing arm link 12 on the same side of one swing arm link 12 is hinged to another top connecting end 131 of the same walking leg 13. The walking mechanism 1 also includes a walking drive source 14 and a transmission assembly 15. The walking drive source 14 is fixedly mounted on the walking frame 11. The walking drive source 14 drives the swing arm links 12 to swing axially relative to the connecting legs 112 along the connecting pin 16 through the transmission assembly 15, thereby causing the walking legs 13 to swing. The walking drive source 14 is a walking power motor, and the transmission component 15 includes a bevel gear set 151, a driving sprocket 152 and a driven sprocket 153, and the driving sprocket 152 and the driven sprocket 153 are connected by a first transmission chain for transmission.

[0055] In this embodiment, the entire device relies on two walking legs 13 to contact the steel mesh 100. The walking drive source 14 drives the bevel gear set 151 (changing the direction of rotation), thereby driving the drive sprocket 152 and the driven sprocket 153 to rotate synchronously. The drive sprocket 152 and the driven sprocket 153 are connected to a bevel gear of the bevel gear set 151 and the swing arm connecting rod 12, which are coaxial and fixed together and rotate synchronously. The swing arm connecting rod 12 makes a circular motion around the connecting pin 16, while simultaneously carrying the walking legs 13 to make a reciprocating motion. When it contacts the surface of the steel mesh 100, it will support the entire device to move forward. When it leaves the steel mesh 100, it completes one step of walking. The distance of one step of walking is related to the length of the swing arm connecting rod 12. There is a walking leg 13 on each side of the swing arm connecting rod 12 connected to the chassis 41. The drive sprocket 152 drives the chain, which drives the driven sprocket 153. Through the transmission shaft, the torque is transmitted to the walking leg 13 on the other side. Driven sprocket 153 is fixed to the drive shaft so that the two walking legs 13 rotate synchronously. When the entire device moves to the required position, the two walking legs 13 lift up at the same time, detaching from the surface of the steel mesh 100. At the same time, the four hydraulic legs 43 start working and extend downward to level the entire device, ensuring that it is in a stable state during subsequent work and guaranteeing its safety.

[0056] It should also be noted that when the entire device needs to turn, the steering motor 46 drives the steering gear 47, the steering gear 47 drives the driven gear 48, the driven gear 48 is fixed to the rectangular frame 111 of the walking frame 11, and the steering shaft 49 of the driven gear 48 can rotate at any angle relative to the chassis 41. While the rectangular frame 111 rotates, it drives the two walking legs 13 to turn synchronously. When the expected angle is reached, the walking drive source 14 can start working, driving the walking legs 13 to move, and then driving the device to move in the adjusted direction. After each angle adjustment, the forward and backward movement of the entire device can be achieved by the forward and reverse rotation of the walking drive source 14.

[0057] In this embodiment, the structure of the walking mechanism 1 is designed to be compact, easy to install, and convenient to operate and maintain. The walking mechanism 1 can move and turn freely on the steel mesh 100 without disturbing the spacing of the reinforcing bars.

[0058] Furthermore, the vibration mechanism 2 includes a vibration body 21 and a frame body 22. The vibration body 21 includes a vibrating rod 211, a winch roller 212, a cable 213, and a lifting assembly 214. The winch roller 212 is mounted on the top of the second end 102 of the rectangular frame 111 via a mounting bracket 215. The vibrating rod 211 is located on one side of the first end 101 of the rectangular frame 111. One end of the cable 213 is connected to the top of the vibrating rod 211, and the other end of the cable 213 is wound around the winch roller 212. The start and stop of the winch roller 212 control the winding of the cable 213, thereby coordinating with the lifting and lowering of the vibrating rod 211. The main frame 22 includes a cable bracket 221 and a vibrator bracket 222. The cable bracket 221 includes two vertical rod assemblies arranged along the longitudinal direction of the top of the rectangular frame 111. The vertical rod assembly includes multiple vertical rod units 2211 arranged at intervals. The cable bracket 221 also includes a horizontal bar 2212 arranged on one side of the two oppositely arranged vertical rod units 2211. The horizontal bar 2212 and the vertical rod units 2211 form a bracket. The bracket is provided with a cable guide groove 223 for supporting the cable 213. A first space is formed between the horizontal bar 2212 and the rectangular frame 111. A telescopic boom 5 is arranged in the first space. The telescopic end of the telescopic boom 5 extends outward relative to the cable bracket 221 and is connected to the vibrator bracket 222. The vibratory rod support 222 includes a vibratory rod limiting beam 2221 and a vibratory platform. The vibratory platform is connected to the telescopic boom 5. The vibratory rod limiting beam 2221 is located below the vibratory platform. The lifting assembly 214 is fixedly installed on the vibratory platform and is fixedly connected to the vibratory rod limiting beam 2221. The cross-section of the vibratory platform is L-shaped. The vibratory platform includes a transverse square steel pipe 2222 and multiple vertical square steel pipes 2223 spaced apart at the bottom along the length of the transverse square steel pipe 2222. Each vertical square steel pipe 2223 has a longitudinal square steel pipe 2224 at its bottom along the longitudinal direction. A slide rail 2225 is provided on the longitudinal square steel pipe 2224 through the telescopic boom 5. A first slide groove 2226 is provided on the slide rail 2225. A second slide groove 2227 is provided on the vibrating rod limiting beam 2221. The vibrating rod 211 extends downward through the gap between the first slide groove 2226, the adjacent longitudinal square steel pipe 2224 and the second slide groove 2227 in sequence. The vibrating rod 211 is installed on the vibrating rod limiting beam 2221 through the vibrating rod limiting plate 216. The lifting component 214 can drive the vibrating rod limiting beam 2221 to rise and fall relative to the vibrating platform, thereby driving the vibrating rod 211 to rise and fall relative to the vibrating platform.

[0059] Furthermore, the vibratory body 21 also includes a lateral adjustment hydraulic cylinder 224 and a lateral position adjustment slider 225. The lateral adjustment hydraulic cylinder 224 is mounted on the slide rail 2225 and can drive the lateral position adjustment slider 225 to reciprocate along the slide rail 2225 in the lateral direction. The cable 213 can pass through the lateral position adjustment slider 225 and the first slide groove 2226 to connect with the vibratory rod 211. Guide sleeves 226 are spaced on the transverse square steel pipe 2222, and guide grooves 227 for the vibratory rod are provided on the guide sleeves 226.

[0060] Furthermore, the vibratory rod 211 adopts a pointed structure, and the pointed structure is made of a semi-rigid material. The top of the vibratory rod 211 is connected to the cable 213 by a spring.

[0061] Furthermore, the lifting assembly 214 includes a lifting motor 2141, a lifting gear 2142, and a lifting rack 2143. The lifting motor 2141 is fixedly installed on the vibrating platform. The driving end of the lifting motor 2141 is provided with the lifting gear 2142, which meshes with the lifting rack 2143 located on one side of it. The bottom of the lifting rack 2143 is connected to one end of the vibrating rod limiting beam 2221.

[0062] After the concrete is laid, the vibration mechanism 2 begins operation. The lifting motor 2141, equipped with a lifting assembly 214, operates on the vibration platform fixed to the vibrator rod bracket 222. This motor drives the lifting gear 2142 to rotate, which in turn drives the lifting rack 2143 to move up and down. The lifting rack 2143 is fixedly connected to the vibrator rod limiting beam 2221. The vibrator rod limiting beam 2221, through the vibrator rod limiting plate 216, fixes all four vibrator rods 211 to it, allowing them to rise and fall synchronously. When a vibrator rod 211 encounters an obstacle during its descent, the lateral position adjusting slider 225 of the vibrator rod 211 can be moved by the lateral adjustment hydraulic cylinder 224. The lateral position adjusting slider 225 slides on the slide rail 2225 to adjust the spacing and position between the individual vibrator rods 211.

[0063] Furthermore, when the vibrator 211 encounters reinforcing steel during its descent, its special pointed semi-rigid structure allows it to avoid the steel, providing a buffering effect so that the vibrator 211 can continue to descend into the concrete and complete the vibration. Both the slide rail 2225 and the vibrator limiting beam 2221 adopt a grooved structure, allowing the vibrator 211 to pass smoothly and slide within the groove. This is an important structural element for adjusting the spacing and position of the vibrator 211. The transverse position adjustment slider 225 of the vibrator 211 adopts a hook structure, ensuring that it moves only in one direction when sliding on the slide rail 2225, thus ensuring the accuracy of the movement. Because the vibrator 211 is relatively long, a guide groove 227 is provided at its rear end (closer to the first end 101) to ensure its integrity during movement and prevent large-scale lateral displacement. Simultaneously, a guide groove 227 is provided at the point of directional change, and a guide sleeve 226 is provided at the rear end of the guide groove 227, allowing the entire guide groove 227 to slide along the transverse square steel pipe 2222 of the vibrator bracket 222, avoiding additional force. After the vibration work is completed, the lifting motor 2141 of the lifting assembly 214 of the vibration platform rotates in the opposite direction, causing the entire assembly of vibrator 211 to move upwards, detaching from the concrete surface, in preparation for subsequent construction.

[0064] Furthermore, the auxiliary working mechanism 3 includes a crossbeam 31 and a process conversion assembly 32. The crossbeam 31 is connected to the telescopic end of the telescopic boom 5, and hydraulic lifting columns 33 are provided at both ends of the bottom of the crossbeam 31. The crossbeam 31 and the process conversion assembly 32 are connected by two hydraulic lifting columns 33. The process conversion assembly 32 includes a process conversion frame 321, a process conversion drive 322, and a process rotating shaft 323. The process conversion frame 321 has a gate-shaped structure. The process conversion drive 322 is located on one side of the process conversion frame 321. The process rotating shaft 323 is located at the bottom opening of the process conversion frame 321. The two ends of the process rotating shaft 323 are rotatably connected to the two ends of the bottom of the process conversion frame 321, and one end of the process rotating shaft 323 passes through the process conversion frame 321 and is connected to the process conversion drive 322. A flattening head 324, a grooving head 325, and an embossing head 326 are provided at intervals along the circumference of the process rotating shaft 323.

[0065] In this embodiment, after the concrete is vibrated, different construction processes are carried out on the concrete surface. Different processes use different tool heads and include techniques such as smoothing, polishing, grooving, and embossing. Previously, these processes required multiple people and multiple machines. To address this, a new multi-process conversion device has been invented, with four working modes. The first mode involves simultaneous concrete feeding via a winch and smoothing via a screed. This work primarily relies on a leveling head 324, which has a winch and a screed. The winch disperses and levels the vibrated concrete, driven by its own drive mechanism. After the winch's operation, the screed is smoothed, and a plate vibrator is installed on the screed to ensure a smooth and dense concrete surface. The winch motor, fixed to the process conversion frame 321, drives the winch sprocket and chain, causing the winch to rotate. Simultaneously, the plate vibrator operates. The entire process conversion assembly 32 is hinged to a crossbeam 31 by two hydraulic lifting columns 33. The crossbeam 31 is hinged to a telescopic boom 5. The movement of the telescopic boom 5 drives the entire process conversion assembly 32 to move. The pitch angle adjustment hydraulic cylinder 35 adjusts the angle between the process conversion assembly 32 and the concrete surface. By adjusting the extension and retraction of the two hydraulic lifting columns 33, the lateral angle of the process conversion assembly 32 is controlled, thereby controlling the cross slope of the concrete. When the concrete is smoothed and the next process is required, the process conversion drive unit 322, including a process conversion motor and a process conversion bevel gear set, operates, driving the process conversion bevel gear set to rotate 90 degrees or 180 degrees, switching between the grooving head 325 and the embossing head 326. The grooving head 325 includes a wide groove scraper and a narrow groove scraper. The wide groove scraper and the narrow groove scraper are arranged at 90-degree intervals around the process shaft 323, spaced apart from the flattening head 324 and the embossing head 326. The wide or narrow groove scraper can define the spacing of the grooves on the concrete, which can be customized according to requirements. Furthermore, the "dovetail" tracks of the wide and narrow groove scrapers are installed on the connecting beam outside the process shaft 323 at the bottom of the open end of the process conversion frame 321, and are limited by a positioning pin (not shown in the figure) to effectively prevent them from slipping during operation. The installation positions of the wide and narrow groove scrapers can also be replaced with scrapers of other shapes and sizes, allowing for arbitrary replacement. When the concrete surface needs embossing, the process conversion motor restarts, driving the process shaft 323 on the process conversion frame 321 to rotate, putting the embossing roller on the embossing head 326 into working condition. The embossing roller rolls, propelled by the movement of the telescopic boom 5, completes the embossing action. Different working tools can be mounted on the process shaft 323 on the process conversion frame 321, allowing for quick installation, removal, and interchangeability. The transverse and longitudinal slopes of the concrete surface are adjustable, making it highly adaptable.

[0066] Furthermore, an angle connecting rod 34 is provided at the top center of the crossbeam 31, and a pitch angle adjusting hydraulic cylinder 35 is connected to the top of the angle connecting rod 34. The fixed end of the pitch angle adjusting hydraulic cylinder 35 is hinged to the telescopic boom 5, and the end of the telescopic boom 5 is hinged to the side wall of the crossbeam 31.

[0067] Furthermore, the finishing mechanism 4 includes a connecting base 41 disposed below the rectangular frame 111, a grinding disc 42 disposed below the connecting base 41, and hydraulic support legs 43 disposed at the four corners of the lower end face of the connecting base 41. The connecting base 41 and the grinding disc 42 are connected by a grinding disc mounting column 44. The top of the grinding disc mounting column 44 passes through the connecting base 41 and is connected to a grinding disc rotating structure 45. The grinding disc rotating structure 45 is disposed between the rectangular frame 111 and the connecting base 41 to drive the grinding disc mounting column 44 to rotate, thereby driving the grinding disc 42 to rotate. A steering motor 46 is disposed between the connecting base 41 and the rectangular frame 111. A steering gear 47 is disposed at the output end of the steering motor 46. The steering gear 47 meshes with a driven gear 48. The driven gear 48 is fixedly mounted on the rectangular frame 111. A steering shaft 49 extends downward from the driven gear 48 and rotates relative to the connecting base 41.

[0068] In this embodiment, when the concrete surface is smoothed and needs to be polished, the telescopic boom 5 retracts to its limit position, the process conversion frame 321 and the vibrator 211 are raised to their highest points, the four hydraulic outriggers 43 are raised to their highest points, and the traveling outriggers 13 move to move the entire device to the concrete surface. Then, the traveling outriggers 13 are raised to their highest positions so that the grinding disc 42 on the concrete surface comes into contact with the concrete surface. The grinding disc rotating structure 45 includes a grinding disc power motor 451, a grinding disc rotating gear 452, and a grinding disc driven gear 453. When the grinding disc power motor 451 works, it drives the grinding disc rotating gear 452 to rotate, which in turn drives the grinding disc driven gear 453 to rotate, thereby driving the grinding disc 42 on the concrete surface to rotate, achieving the purpose of polishing the concrete surface. By controlling the different rotation directions and speeds of the two grinding disc power motors 451, the movement, turning, and other controls of the entire device can be achieved.

[0069] Furthermore, it also includes a reaction braking device 6, which is disposed at the second end 102 of the traveling mechanism 1. The reaction braking device 6 includes a hanger 61 mounted on one end of the telescopic boom 5 and a push hydraulic cylinder 62 mounted on one end of the connecting chassis 41. The extended end of the push hydraulic cylinder 62 is hinged to a linkage rod 64 via a pin 63. The bottom of the hanger 61 has an opening, and the linkage rod 64 passes through the opening and is hinged to an L-shaped transmission rod 65. The lateral end of the L-shaped transmission rod 65 is hinged to the bottom of the hanger 61. The bottom of the opening of the hanger 61 is enclosed by a sealing plate 66. A lateral plate 67 is provided at the bottom of the corner of the L-shaped transmission rod 65, and a hook 68 is provided at the bottom of the lateral plate 67. The hook 68 can engage the steel mesh 100. In this embodiment, by setting the reaction braking device 6, the phenomenon of the traveling mechanism 1 tilting and overturning due to its own weight can be effectively prevented when the auxiliary working mechanism 3 is working, thus better ensuring the stability of the overall device. Furthermore, the reaction braking device 6 has a simple structure, is easy to operate, and has strong applicability.

[0070] A multi-stage concrete construction method, based on a multi-stage concrete construction device, includes the following steps:

[0071] S1. Concrete is placed onto the steel mesh 100 to be laid by an external concrete placing machine.

[0072] S2. Start the vibration mechanism 2, and drive the vibration mechanism 2 to vibrate the concrete through the walking mechanism 1.

[0073] S3, the vibrator 211 moves upward and detaches from the concrete surface to prepare for subsequent construction.

[0074] S4. Start auxiliary working mechanism 3, which can be used to perform leveling, grooving, embossing or finishing work on the concrete surface.

[0075] Example 2:

[0076] See Figures 9-14As shown, unlike Embodiment 1, it also includes a reaction braking assembly 7. This reaction braking assembly 7 replaces the reaction braking device 6 in Embodiment 1. The reaction braking assembly 7 includes a pushing structure 71 mounted on the bottom of the rectangular frame 111 and extending outward, and a snap-fit ​​structure 72 hinged to the walking leg 13. The pushing structure 71 includes a first telescopic rod 711 that can extend and retract in the horizontal direction. A push rod 712 is provided at the bottom of the first telescopic rod 711. The outward extension of the first telescopic rod 711 drives the push rod 712 to move outward. The snap-fit ​​structure 72 includes two opposing second telescopic rods 721 hinged to the outrigger 13. A hinge shaft 722 is fixedly installed between the two second telescopic rods 721. A flipping plate 723 is rotatably mounted on the hinge shaft 722. A brake plate 724 is provided between the two second telescopic rods 721. The flipping plate 723 can flip relative to the brake plate 724 along the hinge shaft 722 and spring back. A hook 725 is provided on the outer wall of the brake plate 724. The second telescopic rods 721 can flip and spring back relative to the outrigger 13. It should be noted that the flipping is achieved by a thrust, and the springback is achieved by a torsion spring.

[0077] Furthermore, the hook 725 has an arc-shaped structure, and a slot for engaging the steel mesh 100 is provided at the front end of the hook 725. Additionally, the top of the arc-shaped structure can also serve as a slot for engaging the steel mesh 100, ensuring that the hook 725 can fit over or under the steel mesh 100. It should also be noted that the drive motor of the first telescopic rod 711 stops working when it encounters a certain resistance. This resistance is a preset value, and the resistance setting is a conventional setting, which will not be elaborated upon further. In this embodiment, the hook 725 can also be used for engagement and positioning on the side where concrete has already formed, which, compared to the hook 68, allows for a better identification of the engagement point from one side for secure fixing.

[0078] in, Figure 11 State 1 is the initial state when the first telescopic rod 711 is not extended; Figure 12 The second state is when the first telescopic rod 711 extends a certain distance, and the push rod 712 abuts against the flip plate 723; Figure 13 The first telescopic rod 711 continues to extend, pushing the flip plate 723 to flip the flip plate 723 outward along the hinge axis 722, so as to drive the brake plate 724 to approach the steel mesh 100 and engage it through the hook 725. Figure 14 When the first telescopic rod 711 extends to its furthest position, the hook 725 is locked in place with the steel mesh 100, thus completing the counter-braking and further ensuring the stability of the overall device.
