[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-8 As shown, a monitorable and adjustable scaffolding construction device includes two bases 1 and two lifting plates 3. Support rods 2 are fixedly installed at the four corners of the top of each of the two bases 1. The lifting plates 3 are slidably installed with respect to the support rods 2. An infrared transmitter 4 is installed at the bottom of one lifting plate 3, and an infrared receiver 5 is installed at the bottom of the other lifting plate 3. A reinforcing structure 6 is provided on the outside of the support rods 2. A lifting mechanism 7 is provided on the top of each base 1. An adjusting mechanism 8 is provided between the two bases 1. A limit plate 10 is provided on the top of each support rod 2. The lifting mechanism 7 includes a protective box 71, which is fixedly installed on the top of the base 1. A rotating rod 72 is rotatably mounted inside the protective box 71 via bearings. A worm gear 73 is keyed to the outside of the rotating rod 72. The external meshing connection of the lifting plate 3 is a worm gear 74, which is rotatably mounted inside the protective box 71 via a bearing. The top of the protective box 71 is penetrated by a crank handle 75. The external symmetrical key of the rotating rod 72 is connected to a first gear 76. The external meshing connection of the first gear 76 is a first rack 77, which is slidably mounted to the protective box 71. The top of the first rack 77 is fixedly mounted to the lifting plate 3. A side door 78 is rotatably mounted on one side of the protective box 71 via a hinge. When the height of the lifting plate 3 needs to be changed, the crank handle 75 is turned to drive the worm gear 74 to rotate. The rotation of the worm gear 74 drives the worm wheel 73 to rotate, which in turn causes the rotating rod 72 to rotate. The rotating rod 72 drives the two first gears 76 to rotate. The first gears 76 drive the first rack 77 to slide, thereby changing the height of the lifting plate 3.

[0031] In this embodiment, the height of the two lifting plates 3 can be changed by two lifting mechanisms 7 respectively. The lifting plates 3 slide along the length of the support rods 2, and the structure is stable. By cooperating with the infrared transmitter 4 and the infrared receiver 5, it can be determined whether the two lifting plates 3 are in a horizontal state. After adjustment, the tensioning mechanism 9 is installed with the four support rods 2 through the disc 61, and then another tensioning mechanism 9 is installed with the two lifting plates 3. The infrared transmitter 4 and the infrared receiver 5 cooperate to monitor whether the two lifting plates 3 are in a horizontal state in real time. If tilting occurs, the workers above need to come down in time. Then the tensioning mechanism 9 is removed and the height of the two lifting plates 3 is readjusted. If it is necessary to lengthen the scaffolding, the second electric cylinder 812 works to effectively drive the two bases 1 to move to both ends, and the tensioning mechanism 9 can extend and retract to effectively change the overall length of the scaffolding and improve its practicality.

[0032] The reinforcement structure 6 includes a disc 61 and a reinforcement rod 62. Both ends of the reinforcement rod 62 are fixedly connected to a locking block 63. The top of both the locking block 63 and the disc 61 are provided with positioning holes 64. A pin 65 is provided between the locking block 63 and the disc 61 through the positioning holes 64. A bolt 66 is provided on the outside of the pin 65 and below the locking block 63. When the reinforcement rod 62 needs to be installed, the locking block 63 is aligned with the disc 61, ensuring that the positioning holes 64 of the locking block 63 and the disc 61 are aligned. Then, the pin 65 is used to penetrate the locking block 63 and the disc 61. Finally, the bolt 66 is installed at the bottom of the pin 65, effectively completing the installation of the reinforcement rod 62 and improving the strength of the scaffold.

[0033] The adjusting mechanism 8 includes a base plate 81. A second gear 82 is rotatably mounted inside the base plate 81 via bearings. A second rack 83 is symmetrically meshed with the outside of the second gear 82. One end of each of the two second racks 83 is fixedly connected to one of the two bases 1. A sliding groove 84 is symmetrically opened on the top of the base plate 81. A sliding strip 85 is slidably mounted inside each of the two sliding grooves 84. One end of each of the two sliding strips 85 is fixedly connected to one of the bases 1. A second electric cylinder 812 is fixedly mounted on the bottom of the base plate 81. The output end of the second electric cylinder 812 is fixedly mounted to one of the bases 1. When the length of the scaffolding needs to be changed, the second electric cylinder 812 extends, moving one of the bases 1 away from the base plate 81. Due to the cooperation of the second gear 82 and the two second racks 83, the other base 1 moves away from the base plate 81 simultaneously, effectively changing the length of the scaffolding. The cooperation of the sliding grooves 84 and the sliding strips 85 improves the stability of the base 1's movement.

[0034] A top plate 86 is fixedly installed on the top of the base plate 81. A fixing frame 87 is symmetrically fixedly installed on the top of the top plate 86. A first electric cylinder 88 is fixedly installed on the bottom of the fixing frame 87. The output end of the first electric cylinder 88 is connected to a suction cup 89. An air pump 810 is set at the center point of the top of the top plate 86. A connecting pipe 811 is set between the air pump 810 and the suction cup 89. Self-locking moving wheels 11 are set at the four corners of the bottom of the two bases 1. The self-locking moving wheels 11 facilitate the movement of the scaffold. When the scaffold moves to the designated position, the self-locking moving wheels 11 are locked. The first electric cylinder 88 works to drive the suction cup 89 to move downward and contact the ground. The air pump 810 works to make the connecting pipe 811 have suction force, effectively sucking out the air between the suction cup 89 and the ground, further improving the stability of the scaffold.

[0035] A tensioning mechanism 9 is provided between the tops of the two lifting plates 3 and between the four discs 61. The tensioning mechanism 9 includes a telescopic sleeve 91, and an installation groove 92 is provided inside the telescopic sleeve 91. A telescopic plate 93 is slidably installed inside the installation groove 92. The bottoms of the telescopic sleeve 91 and the telescopic plate 93 are fixedly connected with locking strips 94. A positioning rod 95 is provided between every two locking strips 94. When the length of the two bases 1 changes, the telescopic plate 93 slides inside the installation groove 92, thereby changing the overall length of the telescopic sleeve 91 and the telescopic plate 93, which can be easily adjusted according to the actual use. When installing the tensioning mechanism 9, the bottom end of the locking strip 94 is aligned with the top of the lifting plate 3 or the top of the disc 61, and the bottom end of the locking strip 94 passes through the lifting plate 3 or the disc 61. Then, the positioning rod 95 passes through the lifting plate 3 or the disc 61, thereby fixing the tensioning mechanism 9 to the lifting plate 3 or the disc 61.

[0036] The working principle of this invention is as follows: the device can be easily moved to the designated construction position by means of the self-locking moving wheel 11 at the bottom of the base 1, and the self-locking moving wheel 11 is locked to complete the initial fixation; then the first electric cylinder 88 on the top plate 86 works to push the suction cup 89 down to make close contact with the ground, and the air pump 810 draws the air between the suction cup 89 and the ground through the connecting pipe 811, and the negative pressure adsorption further improves the stability of the device, laying a solid foundation for subsequent operations;

[0037] When the height of the lifting plate 3 needs to be adjusted, the crank 75 of the lifting mechanism 7 is turned to drive the worm gear 74 to rotate. The worm gear 74 drives the meshing worm wheel 73 and the rotating rod 72 to rotate synchronously. The two first gears 76 on the rotating rod 72 rotate accordingly and drive the meshing first rack 77 to slide along the protective box 71, thereby pushing the lifting plate 3 to move up and down along the support rod 2. The two lifting mechanisms 7 can adjust the height of the corresponding lifting plate 3 respectively. During the adjustment and use of the lifting plate 3, the infrared transmitter 4 and infrared receiver 5 at the bottom cooperate in real time to accurately monitor whether the two lifting plates 3 are in a horizontal state. If tilting occurs, an early warning can be given in time to ensure construction safety.

[0038] When installing the reinforcing structure 6, align the locking blocks 63 at both ends of the reinforcing rod 62 with the disc 61 outside the support rod 2, so that the locking blocks 63 are aligned with the positioning holes 64 of the disc 61. Insert the pin 65 through the positioning holes 64, and then install the bolt 66 at the bottom of the pin 65 to complete the fixing of the reinforcing rod 62 and improve the overall structural strength of the device. After the two lifting plates 3 are adjusted to the predetermined height and are in a horizontal state by the lifting mechanism 7, they can be installed between the two lifting plates 3. When installing the tensioning mechanism 9, insert the bottom end of the telescopic sleeve 91 and the locking strip 94 at the bottom of the telescopic plate 93 through the top of the lifting plate 3 or the top of the disc 61, and then insert the positioning rod 95 through the locking strip 94 to fix the tensioning mechanism 9 to the lifting plate 3 and the disc 61.

[0039] When adjusting the overall length of the scaffolding according to construction needs, the second electric cylinder 812 of the adjusting mechanism 8 extends to push one of the bases 1 to move. The base 1 drives the connected second rack 83 to move, which in turn drives the second gear 82 to rotate. This causes the second rack 83 on the other side to drive the other base 1 to move synchronously in the opposite direction, thereby adjusting the distance between the two bases 1. The sliding cooperation between the slide groove 84 and the slide bar 85 ensures the stability of the movement of the base 1. While the distance between the bases 1 changes, the telescopic plate 93 of the tensioning mechanism 9 slides synchronously in the mounting groove 92 of the telescopic sleeve 91, thereby achieving adaptive adjustment of the overall length of the tensioning mechanism 9 to meet the needs of scaffolding length changes.

[0040] If the infrared transmitter 4 and infrared receiver 5 detect that the lifting plate 3 is tilted during construction, the staff must be evacuated first. After removing the tension mechanism 9, the height of the lifting plate 3 should be readjusted to a horizontal state through the lifting mechanism 7. Then, the tension mechanism 9 should be reinstalled. After construction is completed, the tension mechanism 9 should be removed first, and the lifting plate 3 should be reset to the initial height through the lifting mechanism 7. The second electric cylinder 812 should be controlled to retract to reset the two bases 1. Then, the air pump 810 should stop working, and the first electric cylinder 88 should drive the suction cup 89 to move up and off the ground. The self-locking moving wheel 11 should be unlocked, and the device can be pushed to the designated storage location.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
