[0001] The utility model relates to the field of building construction, in particular to a building construction safety frame. Background Technique

[0002] During the building construction process, scaffolding is needed for support to facilitate workers to operate on the wall and ceiling at a high place.

[0003] After retrieval, a patent with the Chinese patent application number 202022643013.4 discloses a scaffolding for building construction, including a column. One end surface of the column is fixedly welded with a connecting plug rod. The plug rod is movably inserted into a socket cylinder. A cross bar is fixedly welded on one side surface of the column, and a hinged skeleton is installed on the other side surface. The hinged skeleton is hinged with a hinge shaft.

During movement, manual pushing is required, and rapid movement cannot be achieved. When moving, the device needs to be lifted or pushed rigidly, which is time-consuming and laborious and may cause damage to the floor and affect construction. During the disassembly, assembly and movement processes, it is easy to cause injuries to the operators. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 - 5 shown, a construction safety frame includes a bottom plate 1, on which a motor 2, a hydraulic pump 4 and a handrail 12 are installed. A base 14 is installed below the bottom plate 1. A plurality of support columns 1111 are fixedly connected above the bottom plate 1 and are arranged in a rectangular shape. A limiting mechanism is sleeved on the support columns 1111 and is slidably connected to the support columns 1111. A lifting plate 13 is fixedly connected below the limiting mechanism. A lifting mechanism is connected below the lifting plate 13. One end of the lifting mechanism away from the lifting plate 13 is connected to the motor 2. The hydraulic pump 4 is connected to a moving mechanism, and the moving mechanism is installed inside the bottom plate 1.

[0022] When the hydraulic pump 4 is started, the hydraulic pump 4 drives the piston rod 42 to move. The up and down displacement of the moving mechanism is driven by the movement of the piston rod 42. When the moving mechanism moves downward, the universal wheels 141 touch the ground and lift the device, and the device can be pushed to the construction position. When reaching the construction position, the motor 2 is started, and the motor 2 drives the lifting mechanism to lift the lifting plate 13 to the required height, and then the height and positioning are restricted by the limiting mechanism to prevent the lifting plate 13 from descending during the construction process.

[0023] Preferably, a limiting groove 111 is opened on one side of the support column 1111, and a limiting tooth 112 inclined upward is arranged in the limiting groove 111.

[0024] Preferably, the limiting mechanism includes a limiting sleeve 3 sleeved on the support column 1111. The lower end of the limiting sleeve 3 is fixedly connected to the lifting plate 13 and extends downward through the lifting plate 13. A limiting port 31 is opened on the outer wall of the limiting sleeve 3, and the limiting port 31 corresponds to the limiting groove 111. A limiting plate 32 is installed at the limiting port 31. A rotating shaft 323 is fixedly connected to the middle of the limiting plate 32. Both ends of the rotating shaft 323 penetrate through the limiting plate 32 and extend outward to the side wall of the limiting port 31 and are rotatably connected to the side wall of the limiting port 31. Torsion springs 321 are sleeved on both ends of the rotating shaft 323, and both ends of the torsion springs 321 are fixedly connected to the side wall of the limiting port 31 and the inside of the limiting plate 32 respectively. A limiting frame 33 is installed at the upper end of the limiting port 31, and the limiting frame 33 is fixedly connected to the outer wall of the limiting sleeve 3. The limiting frame 33 is threadedly connected to a limiting bolt 34. A through hole 322 is opened at the top of the limiting plate 32.

[0025] With the above solution, when the motor 2 drives the lifting mechanism to move the lifting plate 13 upward, the limit sleeve 3 will move upward along the support column 11 following the lifting plate 13. The limit plate 32 will be in an inclined state under the action of the torsion spring 321. The limit plate 32 will rotate along the rotating shaft 323 and the bottom of the limit plate 32 will rotate into the limit groove 111. When the lifting plate 13 rises to the required height, the bottom of the limit plate 32 will abut against the inner wall of the limit tooth 112. At this time, the limit plate 32 will no longer rotate. Since the limit plate 32 is fixedly connected to the rotating shaft 323 and both ends of the rotating shaft 323 are connected to the inner wall of the limit sleeve 3, under the action of the limit plate 32, the lifting plate 13 is positioned at the required height and cannot descend; when it needs to descend, start the motor 2 to rotate slightly, so that the lifting plate 13 moves slightly upward along the support column 11. The limit plate 32 no longer abuts against the inner wall of the limit tooth 112. At this time, remove the limit bolt 34, press the upper end of the limit plate 32, so that the upper end of the limit plate 32 rotates along the rotating shaft 323 between the limit frames 33, pass the limit bolt 34 through the through hole 322 on the limit plate 32 and screw it to the other side of the limit frame 33 to limit the limit plate 32. Repeat this operation to fix the limit plate 32 in turn. After the fixing is completed, reverse the motor 2 to lower the lifting plate 13 to complete the lifting and lowering operation of the lifting plate 13.

[0026] Preferably, the lifting mechanism includes a motor 2. The output end of the motor 2 is fixedly connected to a driving shaft 21. Two groups of first support plates 23 are fixedly connected to the driving shaft 21. The end of the first support plate 23 away from the driving shaft 21 is rotatably connected to a second support plate 231. The end of the first support plate 23 away from the driving shaft 21 is hinged to the second support plate 231. The end of the second support plate 231 away from the first support plate 23 is hinged to both sides of the bottom of the lifting plate 13. A first fixing frame 22 is rotatably connected to the driving shaft 21. First fixing frames 22 are arranged on both sides of the first support plate 23.

[0027] With the above solution, when the motor 2 is started to rotate, the motor 2 drives the driving shaft 21 to rotate. Since the first support plate 23 is fixedly connected to the driving shaft 21 and the end of the first support plate 23 away from the driving shaft 21 is hinged to the second support plate 231, when the driving shaft 21 rotates, the first support plate 23 will rotate following the driving shaft 21. The end of the first support plate 23 away from the driving shaft 21 will make a circular motion with the driving shaft 21 as the center. One end of the second support plate 231 is hinged to one end of the first support plate 23. Under the action of the first support plate 23, the second support plate 231 rotates following the first support plate 23. The end of the second support plate 231 away from the first support plate 23 is rotatably connected to the bottom of the lifting plate 13. The lifting plate 13 will move up and down along the support column 11 under the action of the second support plate 231.

[0028] Preferably, the moving mechanism includes a hydraulic pump 4. The hydraulic pump 4 is connected to a hydraulic pipeline 41. One end of the hydraulic pipeline 41 away from the hydraulic pump 4 is connected to a piston rod 42. Both ends of the piston rod 42 are fixedly connected with first top blocks 43 and are located on both sides of the piston rod 42. The first top blocks 43 are in the shape of right trapezoids. Chute grooves 431 are formed in both the hypotenuse and the top end away from the piston rod 42 of the first top blocks 43. The first top blocks 43 are abutted against by first guide wheels 441. The first guide wheels 441 are abutted in the chute grooves 431. The first guide wheels 441 are rotatably connected to a top rod 44. The other end of the top rod 44 extends outwards through the side wall of the bottom plate 1. A second baffle 452 is fixedly connected to the top rod 44 near the inner wall of the bottom plate 1. A first baffle 451 is fixedly connected to the end of the top rod 44 away from the first top block 43. A first spring 45 is arranged between the second baffle 452 and the inner wall of the bottom plate 1. The first spring 45 is sleeved around the top rod 44. Both ends of the first spring 45 are fixed to the second baffle 452 and the inner wall of the bottom plate 1 respectively.

[0029] With the above solution, when the hydraulic pump 4 works, the piston rod 42 moves. When the piston rod 42 moves in the direction away from the hydraulic pump 4, the piston rod 42 will drive the first top block 43 to move. When the first top block 43 follows the piston rod 42 to move, since the first guide wheel 441 is abutted in the chute groove 431 of the first top block 43, under the action of the first top block 43, the top rod 44 will move in the direction away from the first top block 43. At this time, the first spring 45 will be compressed. Both ends of the first spring 45 are fixedly connected to the second baffle 452 and the inner wall of the bottom plate 1 respectively, which is convenient for the top rod 44 to return to its original position. The first baffle 451 prevents the top rod 44 from returning too much.

[0030] Preferably, a second top block 442 is fixedly connected to the top rod 44 near the second baffle 452. The second top block 442 is located at the bottom of the top rod 44. The second top block 442 is in the shape of a right trapezoid. Chute grooves 431 are formed in both the hypotenuse and the top end away from the top rod 44 of the second top block 442. The second top block 442 is abutted against by a second guide wheel 46. The second guide wheel 46 is abutted in the chute groove 431. The second guide wheel 46 is rotatably connected to a connecting frame 461. A sliding column 47 is fixedly connected to the bottom of the connecting frame 461. A second spring 471 is sleeved around the sliding column 47. Both ends of the second spring 471 are fixedly connected to the bottom of the connecting frame 461 and the inner bottom surface of the bottom plate 1 respectively. The sliding column 47 penetrates through the bottom plate 1 below and is fixedly connected to a universal wheel 141.

[0031] With the above solution, when the ejector rod 44 moves under the action of the piston rod 42, the principle of the second ejecting block 442 below the ejector rod 44 is the same as that of the first ejecting block 43. Under the action of the second ejecting block 442, the second guide wheel 46 moves along the sliding groove 431, driving the connecting frame 461 and the sliding column 47 to move downward. A universal wheel 141 is fixedly connected below the sliding column 47. When the sliding column 47 moves downward, the universal wheel 141 gradually touches the ground, lifting the entire device. The handrail 12 can be pushed to shift the device. The second spring 471 is used to return the sliding column 47 and the connecting frame 461 to their original positions.

[0032] Preferably, two groups of second fixing frames 411 are fixedly connected to the bottom plate 1. The upper ends of the second fixing frames 411 are sleeved on the piston rod 42, and the second fixing frames 411 are respectively located at both ends of the piston rod 42.

[0033] Preferably, the inside of the base 14 is hollow, and the lower end of the sliding column 47 and the universal wheel 141 are located inside the base 14.

[0034] With the above solution, the second fixing frame 411 is used to fix the piston rod 42, and the piston rod 42 is slidably connected to the second fixing frame 411; the sliding column 47 and the universal wheel 141 can slide up and down conveniently inside the base 14.

[0035] Working principle: During construction, the hydraulic pump 4 is turned on. The hydraulic pump 4 drives the piston rod 42 to move away from the hydraulic pump 4. Driven by the piston rod 42, the first ejecting block 43 drives the ejector rod 44 to move away from the first ejecting block 43, thereby driving the second ejecting block 442 below the ejector rod 44 to move downward. Under the action of the second ejecting block 442, the connecting frame 461 and the sliding column 47 move downward toward the lower part of the device. The sliding column 47 drives the universal wheel 141 to move. The universal wheel 141 moves from inside the base 14 to the ground. Finally, the universal wheel 141 touches the ground and slowly lifts the device off the ground under the action of the hydraulic pump 4. At this time, the handrail 12 can be pushed to move the device to the construction site. When reaching the site, the hydraulic pump 4 is driven in the reverse direction to make the piston rod 42 move in the reverse direction. Under the action of the first spring 45 and the second spring 471, the sliding column 47 and the ejector rod 44 both return to their original positions, and the universal wheel 141 returns to the inside of the base 14 again. At this time, the base 14 touches the ground to support the device and prevent the device from shaking due to the support of the universal wheel 141; the motor 2 is started. Driven by the driving shaft 21, the first support plate 23 and the second support plate 231 lift the lifting plate 13. The limiting plate 32 abuts against the limiting teeth 112 to limit the lifting plate 13 to the required height for construction. After construction, by pressing the limiting plate 32, the limiting bolt 34 passes through the through hole 322 to limit it, so that the limiting plate 32 no longer abuts against the limiting teeth 322. The motor 2 is reversed to return the lifting plate 13 to its original position, completing the lifting operation.

[0036] The utility model is not limited to the above specific embodiments. Those of ordinary skill in the art can make various changes starting from the above concepts without creative efforts, and all such changes fall within the protection scope of the utility model.
