[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides, for example Figure 1-6 The safety construction frame for civil engineering construction shown includes a base plate 1, four moving mechanisms 2, a first support mechanism 3, a second support mechanism 4, a sliding mechanism 5, a lifting mechanism, and a load-bearing frame 12.
[0028] The base plate 1 has a storage slot 14 in the middle of each of the four side walls, and each storage slot 14 has a first support mechanism 3.
[0029] Each first support mechanism 3 includes an L-shaped support plate 31, a placement plate 32, a fixing plate 33, and three first bolts 34. The horizontal wall of the L-shaped support plate 31 is slidably inserted into the storage groove 14, and the vertical wall of the L-shaped support plate 31 is in contact with the opening of the storage groove 14. The middle of the top wall of the placement plate 32 is fixedly connected to the bottom of the vertical wall of the L-shaped support plate 31. The fixing plate 33 is fixedly connected to the side wall of the bottom plate 1 above the opening of the storage groove 14. The top wall of the fixing plate 33 is provided with three second bolt holes 36 at equal intervals. The top wall of the horizontal wall of the L-shaped support plate 31 is provided with a row of first bolt holes 35 at equal intervals at the positions corresponding to the three second bolt holes 36. Each of the three first bolt holes 35 in a row is threadedly connected to a first bolt 34 with the corresponding second bolt hole 36.
[0030] All four moving mechanisms 2 are located on the bottom wall of the base plate 1, the second supporting mechanism 4 is located in the middle of the bottom wall of the base plate 1, the sliding mechanism 5 is located on the top wall of the base plate 1, the lifting mechanism is located on the sliding mechanism 5, and the bearing frame 12 is located on the lifting mechanism.
[0031] Workers can move the construction scaffold device to the required construction location using the casters 23 (which have a self-locking function). When using the scaffold device, connect it to a power source. Workers first unscrew the first bolt 34, then pull out the four L-shaped support plates 31. The length of the pulled-out L-shaped support plates 31 can be flexibly adjusted according to the placement area of the construction site. After pulling out the appropriate length, screw the three first bolts 34 on the four L-shaped support plates 31 into the three second bolt holes 36 and the corresponding three first bolt holes 35, respectively, to fix the L-shaped support plates 31. At this time, the L-shaped support plates 31 are in a suspended state. Then, the controller synchronously starts the four second cylinders 22, retracting the casters 23 into the inner cavity of the retraction shell 21. At this time, the bottom of the retraction shell 21 is flush with the bottom of the placement plate 32. The base plate 1 is placed on the ground. The placement plates 32 on the four L-shaped support plates 31 enhance the stability of the base plate 1. After placement, the controller synchronously starts the two first cylinders 44. The first cylinders 44 drive the multiple fixing piles 42 on the connecting plate 43 to drive into the ground, further enhancing the stability of the base plate 1. Then, the T-shaped sliding plate 52 slides on the L-shaped sliding seat 51 to adjust the position of the load-bearing frame 12. After adjustment, the T-shaped sliding plate 52 is fixed. The workers stand inside the load-bearing frame 12. The controller then starts the telescopic frame 6, which moves the load-bearing frame 12 upward. The limit rod 7 limits the movement of the load-bearing frame 12 to prevent it from tipping over and improves the stability of the load-bearing frame 12 during movement. When the load-bearing frame 12 is raised to a suitable height, the workers begin construction operations.
[0032] Four moving mechanisms 2 are respectively located near the four corners of the bottom wall of the base plate 1. Each moving mechanism 2 includes a retractable shell 21, a second cylinder 22, and a caster wheel 23. The top wall of the retractable shell 21 is fixedly connected to the bottom wall of the base plate 1. The top of the inner cavity of the retractable shell 21 is provided with an installation port. The fixed wall of the second cylinder 22 is embedded in the installation port. The mounting plate of the caster wheel 23 is fixedly connected to the telescopic end of the second cylinder 22. The second support mechanism 4 includes a rectangular surrounding plate 41, two first cylinders 44, a connecting plate 43, and multiple fixing posts 42. The top wall of the surrounding plate 41 is fixedly connected to the bottom of the base plate 1. At the middle of the wall, the fixed ends of the two first cylinders 44 are fixedly connected to the middle of the bottom wall of the base plate 1 near both sides, and the two first cylinders 44 are located inside the enclosure plate 41. The top wall of the connecting plate 43 is fixedly connected to the telescopic ends of the two first cylinders 44. The fixed ends of multiple fixing piles 42 are evenly distributed on the bottom wall of the connecting plate 43, and the fixed ends of the fixing piles 42 are fixedly connected to the connecting plate 43. The bottom wall of the placement plate 32 is at the same horizontal position as the bottom wall of the shrink shell 21. The height of the enclosure plate 41 is half the height of the shrink shell 21. The storage groove 14 matches the transverse wall of the L-shaped support plate 31.
[0033] The casters 23 facilitate the movement of the device, allowing workers to move the construction frame to the required construction location for convenient construction. Once moved to the construction location, the controller simultaneously activates four second cylinders 22, retracting the casters 23 into the inner cavity of the shrink shell 21. At this time, the bottom of the shrink shell 21 and the bottom of the placement plate 32 will fall to the ground. The placement plates 32 on the four L-shaped support plates 31 enhance the stability of the base plate 1. Then, the controller simultaneously activates two first cylinders 44, which drive multiple fixing piles 42 on the connecting plate 43 (the use of fixing piles 42 can be selected according to the ground conditions, such as not using them on cement ground and using them on soil ground) into the ground, further enhancing the stability of the base plate 1 and preventing the construction frame from tipping over. When the fixing piles 42 are not used, the first cylinders 44 drive the multiple fixing piles 42 on the connecting plate 43 to move upward, and the enclosure plate 41 protects the connecting plate 43 and the first cylinders 44.
[0034] The sliding mechanism 5 includes two L-shaped slide blocks 51, a T-shaped slide plate 52, and four second bolts 53. The two L-shaped slide blocks 51 are fixedly connected to the top wall of the base plate 1 near both ends, and the two L-shaped slide blocks 51 are symmetrically arranged. Multiple fourth bolt holes 55 are evenly spaced on the limiting walls of the two L-shaped slide blocks 51. The two protruding walls of the T-shaped slide plate 52 rest on the limiting walls of the two L-shaped slide blocks 51, and the bottom of the middle short wall of the T-shaped slide plate 52 rests on the sliding platform of the two L-shaped slide blocks 51. Two third bolt holes 54 are opened in the middle of the top of each of the two protruding walls of the T-shaped slide plate 52. The positions of the two third bolt holes 54 at the same end of the T-shaped slide plate 52 are aligned with the positions of two fourth bolt holes 55 on the limiting walls of the L-shaped slide blocks 51. Correspondingly, each third bolt hole 54 is threadedly connected to a corresponding fourth bolt hole 55 with a second bolt 53. The lifting mechanism includes a telescopic frame 6 and four limiting plates 9. A limiting rod 7 is fixedly connected to the top of the two protruding walls of the T-shaped slide plate 52 near both sides. A limiting plate 8 is slidably sleeved between the two limiting rods 7 at the same end, and the two limiting plates 8 are at the same horizontal position. The bottom of the four limiting plates 9 is fixedly connected to the top of the four limiting rods 7 respectively. The connecting end of the bottom of the telescopic frame 6 is fixedly connected to the top of the T-shaped slide plate 52. The bottom wall of the bearing frame 12 is fixedly connected to the connecting end of the top of the telescopic frame 6. The front and rear side walls of the bearing frame 12 are fixedly connected to the adjacent side walls of the two limiting plates 8 near the top respectively.
[0035] By unscrewing the second bolt 53, the T-shaped slide plate 52 can slide on the slide table of the L-shaped slide block 51, thereby adjusting the position of the bearing frame 12 so that the bearing frame 12 is closer to the construction site, making it easier for workers to carry out the construction. After adjusting the position of the bearing frame 12, the second bolt 53 is screwed into the third bolt hole 54 and the corresponding fourth bolt hole 55 respectively to fix the T-shaped slide plate 52. The telescopic frame 6 is started to drive the bearing frame 12 to move upward. The cooperation between the limiting rod 7 and the limiting plate 8 keeps the bearing frame 12 balanced during the movement, improving the stability of the movement of the bearing frame 12. The limiting piece 9 limits the movement range of the limiting plate 8 to prevent the limiting plate 8 from moving out of the limiting rod 7.
[0036] A railing handrail 10 is fixedly connected to the top of both the front and rear side walls of the load-bearing frame 12. Anti-slip strips 13 are fixedly connected at equal intervals to the bottom wall of the inner cavity of the load-bearing frame 12. A storage box 11 is fixedly connected to the right side wall of the load-bearing frame 12 near the top.
[0037] The anti-slip strip 13 can effectively reduce the problem of workers slipping and falling. Workers can hold onto the railing handrail 10 when standing on the support frame 12 to avoid falling due to instability, thus improving the safety of using the construction scaffold. The storage box 11 can hold some construction tools to avoid placing too many construction tools on the support frame 12, which would make the support frame 12 too small.
[0038] The two first cylinders 44, the four second cylinders 22, and the telescopic frame 6 are all electrically connected to an external controller.
[0039] The first cylinder 44, four second cylinders 22, and telescopic frame 6 are controlled by a controller, which facilitates the use of the construction frame.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
