[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] like Figure 1-8As shown, the embodiment of the present application discloses a multifunctional scaffold for civil engineering construction, including a scaffold body 1. The support rods 2 at the four corners of the scaffold body 1 are all solid rods. Three receiving grooves 21 are evenly distributed about the axis of the support rod 2 on the side wall of each support rod 2 near its lower end. A reinforcement mechanism 3 is provided on each support rod 2. The reinforcement mechanism 3 includes a reinforcement assembly 31. The number of groups of reinforcement assemblies 31 corresponding to each support rod 2 is the same as the number of receiving grooves 21. The positions of the reinforcement assemblies 31 correspond one-to-one to the positions of the receiving grooves 21. The reinforcement assembly 31 includes a slider 311 that slides with the receiving groove 21, a connecting shaft 312 that is provided through the slider 311 and is rotatably connected, and a reinforcement rod 313 that is fixedly sleeved on the connecting shaft 312. The reinforcement mechanism 3 also includes a transmission assembly 32 for driving multiple connecting shafts 312 corresponding to the same support rod 2 to rotate synchronously, a linkage assembly 33 for driving multiple connecting shafts 312 corresponding to adjacent support rods 2 to rotate synchronously, and a lifting assembly 34 for driving multiple groups of reinforcement assemblies 31 to rise and fall synchronously.

[0029] In order to enhance the stability of the scaffolding during use, the staff only needs to drive the multiple connecting shafts 312 corresponding to the four support rods 2 to rotate synchronously through the linkage assembly 33 and the transmission assembly 32, so that the reinforcement rods 313 fixed to the connecting shafts 312 rotate synchronously until the multiple reinforcement rods 313 corresponding to the four support rods 2 are synchronously opened. The staff can then control the multiple reinforcement rods 313 in the multiple groups of reinforcement assemblies 31 to descend synchronously through the lifting assembly 34 until the lower ends of the multiple reinforcement rods 313 are in contact with the ground. The cooperation of the multiple reinforcement rods 313 enhances the stability of the connection between the support rods 2 and the ground, which is conducive to ensuring the stability of the scaffolding body 1 during use.

[0030] The lower end of the support rod 2 is provided with a sliding cavity 22 and an installation cavity 23 from bottom to top, a movable block 4 is provided in the installation cavity 23, and a installation opening 3131 is provided at the top of the reinforcement rod 313. The transmission assembly 32 includes a transmission unit 3211. The transmission unit 3211 includes an I-shaped block 32111 that slides with the inner wall of the installation cavity 23, a transmission rod 32112 that is arranged on the I-shaped block 32111 and is rotatably connected, a driven bevel gear 32113 fixed at one end of the transmission rod 32112 and located in the installation cavity 23, a worm 32114 fixed at the other end of the transmission rod 32112 and located in the installation opening 3131, and a worm wheel 32115 fixedly sleeved on the connecting shaft 312 and located in the installation opening 3131. The worm wheel 32115 is meshed with the worm 32114. The transmission assembly 32 also includes an active unit 3212 for driving multiple driven bevel gears 32113 in the same support rod 2 to rotate synchronously.

[0031] Each support rod 2 is provided with a pair of slide grooves 24 connected to the accommodating groove 21, and the two pairs of slide grooves 24 are respectively located on both sides of the accommodating groove 21. The support rod 2 is provided with a connecting hole 25 that slides with the I-block 32111 and is connected to the mounting cavity 23 and the accommodating groove 21. The active unit 3212 includes an upper motor 32121 fixed to the top of the movable block 4, a rotating shaft 32122 fixed to the output end of the upper motor 32121, and a driving bevel gear 32123 fixed to the upper end of the rotating shaft 32122 and meshing with the driven bevel gear 32113.

[0032] It is worth noting that: when it is necessary to adjust the reinforcement rod 313 to unfold from the accommodating slot 21, the staff only needs to start the upper motor 32121. After the upper motor 32121 works, it drives the rotating shaft 32122 and the active bevel gear 32123 fixed to the rotating shaft 32122 to rotate, so that the driven bevel gear 32113 meshing with the active bevel gear 32123, the transmission rod 32112 fixed to the driven bevel gear 32113, the worm 32114 fixed to the transmission rod 32112, the worm wheel 32115 meshing with the worm 32114, the connecting shaft 312 fixed to the worm wheel 32115, and the reinforcement rod 313 fixed to the connecting shaft 312 all rotate until the multiple reinforcement rods 313 corresponding to each support rod 2 are opened synchronously, and then the upper motor 32121 can be turned off.

[0033] The rotating shafts 32122 in the three groups of transmission components 32 other than the upper motor 32121 are directly connected to the top of the corresponding movable block 4 for rotation. The linkage component 33 includes an upper synchronous wheel 331 fixedly mounted on the rotating shaft 32122. There are four upper synchronous wheels 331 and they are respectively arranged on the four rotating shafts 32122. The linkage component 33 also includes an upper synchronous belt 332 for connecting with the four upper synchronous wheels 331 and engaging with the upper synchronous wheels 331. A movable through hole 26 that is connected to the mounting cavity 23 and for the upper synchronous belt 332 to move up and down is provided at a position on the side wall of the support rod 2 corresponding to the upper synchronous belt 332.

[0034] After the upper motor 32121 works, it drives the rotating shaft 32122 to rotate. Under the action of the upper synchronous belt 332, the four upper synchronous wheels 331 rotate synchronously, so that the multiple reinforcement rods 313 corresponding to the four support rods 2 are opened synchronously, so that after the lifting assembly 34 controls the reinforcement assembly 31 to descend, the multiple support rods 2 cooperate and reinforce the support rods 2, which is beneficial to improving the stability of the scaffolding during use. In this embodiment, the upper synchronous belt 332 descends in the movable through hole 26 during the descent of the reinforcement assembly 31.

[0035] An L-shaped connecting rod 41 is fixed to the top of the movable block 4 at a position corresponding to the connecting hole 25. The width of the L-shaped connecting rod 41 is smaller than the width of the connecting hole 25. The upper end of the vertical section of the L-shaped connecting rod 41 is fixed to the bottom of the I-shaped block 32111. The number of L-shaped connecting rods 41 is equal to the number of I-shaped blocks 32111 and the positions correspond one to one. The lower end of each support rod 2 is fixed with a bottom block 5. The lifting assembly 34 includes a lifting unit 341. The lifting unit 341 includes a rectangular sleeve that rotates and slides with the sliding cavity 22. 3411 and a threaded rod 3412 that passes through the bottom of the rectangular sleeve 3411 and is threadedly connected. The upper end of the rectangular sleeve 3411 is fixed to the bottom of the movable block 4. A lower motor 51 is fixed to the top of one of the bottom blocks 5. The output end of the lower motor 51 is coaxial and fixed with its corresponding threaded rod 3412. The lower ends of the other three threaded rods 3412 are respectively rotatably connected to their corresponding bottom blocks 5. The lifting assembly 34 also includes a linkage unit 342 for driving the four threaded rods 3412 to rotate synchronously.

[0036] When using the lifting assembly 34 to control the reinforcement assembly 31 to descend, the staff only needs to start the lower motor 51, and the lower motor 51 drives the threaded rod 3412 fixed to its output end to rotate. Under the action of the linkage unit 342, the four threaded rods 3412 rotate synchronously. Since the threaded rod 3412 is threadedly connected to the rectangular sleeve 3411, the rectangular sleeve 3411 slides with the sliding cavity 22, so that the rectangular sleeve 3411 is lifted and lowered in the vertical direction, thereby driving the movable block 4 fixed to the rectangular sleeve 3411. , the L-shaped connecting rod 41 fixed to the movable block 4, the I-shaped block 32111 fixed to the L-shaped connecting rod 41, the transmission rod 32112 rotatably installed on the I-shaped block 32111, the worm 32114 fixed to the transmission rod 32112, the worm wheel 32115 engaged with the worm 32114, the connecting shaft 312 fixed to the worm wheel 32115, and the reinforcement rod 313 fixed to the connecting shaft 312 all descend synchronously, so that multiple reinforcement rods 313 cooperate and complete the reinforcement effect of the scaffolding support rod 2.

[0037] The linkage unit 342 includes a lower synchronous wheel 3421 fixedly mounted on the threaded rod 3412. There are four lower synchronous wheels 3421 and they are respectively arranged on the four threaded rods 3412. The linkage unit 342 also includes a lower synchronous belt 3422 for connecting to the four lower synchronous wheels 3421 and engaging with the lower synchronous wheels 3421. The width of the movable through hole 26 is greater than the width of the lower synchronous belt 3422, and the bottom of the movable through hole 26 is lower than the bottom of the lower synchronous belt 3422.

[0038] After the lower motor 51 works and causes the threaded rod 3412 to rotate, the four lower synchronous wheels 3421 keep rotating synchronously under the transmission action of the lower synchronous belt 3422, so that the four rectangular sleeves 3411 are synchronously lowered, thereby facilitating the synchronous descending of the multiple reinforcement rods 313 corresponding to the four support rods 2 to a position in contact with the ground, so that the multiple reinforcement rods 313 can cooperate and complete the reinforcement work of the scaffolding.

[0039] A protective cover 27 is fixed between two adjacent support rods 2. The fixed end of the protective cover 27 is arranged around the movable through hole 26. The upper synchronous belt 332 and the lower synchronous belt 3422 are both located within the protective cover 27. The protective cover 27 provides good protection for the upper synchronous belt 332 and the lower synchronous belt 3422, not only enhancing the safety of the upper synchronous belt 332 and the lower synchronous belt 3422 during movement, but also reducing the speed at which the upper synchronous belt 332 and the lower synchronous belt 3422 age.

[0040] To ensure the aesthetics of the support rod 2, when the reinforcement rod 313 is folded into the receiving groove 21, the side of the reinforcement rod 313 away from the axis of the support rod 2 is flush with the notch of the receiving groove 21. To ensure the reinforcing effect of the reinforcement rod 313, the lower end of the reinforcement rod 313 is bent toward the side closer to the axis of the support rod 2. To facilitate the smooth folding of the reinforcement rod 313 into the receiving groove 21, a clearance portion 28 is provided at the position of the receiving groove 21 corresponding to the lower end of the reinforcement rod 313.

[0041] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
