[0018] 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; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0019] like Figure 1-8As shown in the figure, an embodiment of the present application discloses a multi-functional scaffolding for civil engineering construction, including a scaffolding body 1. The support rods 2 at the four corners of the scaffolding body 1 are all solid rods. Three receiving grooves 21 evenly distributed about the axis of each support rod 2 are provided at a position 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 component 31. The number of groups of the reinforcement component 31 corresponding to each support rod 2 and the number of receiving grooves 21 are both 3. The positions of the reinforcement component 31 correspond to the positions of the receiving grooves 21 one by one. The reinforcement component 31 includes a slider 311 slidably engaged with the receiving groove 21, a connecting shaft 312 penetrating through the slider 311 and rotatably connected, and a reinforcement rod 313 fixedly sleeved on the connecting shaft 312. The reinforcement mechanism 3 further includes a transmission component 32 for driving the synchronous rotation of a plurality of connecting shafts 312 corresponding to the same support rod 2, a linkage component 33 for driving the synchronous rotation of a plurality of connecting shafts 312 corresponding to adjacent support rods 2, and a lifting component 34 for driving the synchronous lifting of multiple groups of reinforcement components 31.

[0020] To enhance the stability during the use of the scaffolding, the staff only needs to simultaneously drive the synchronous rotation of a plurality of connecting shafts 312 corresponding to the four support rods 2 through the linkage component 33 and the transmission component 32, so that the reinforcement rods 313 fixed to the connecting shafts 312 rotate synchronously. Until the plurality of reinforcement rods 313 corresponding to the four support rods 2 are synchronously opened, the staff can then control the synchronous descent of the plurality of reinforcement rods 313 in multiple groups of reinforcement components 31 through the lifting component 34 until the lower ends of the plurality of reinforcement rods 313 are all in contact with the ground. The multiple reinforcement rods 313 cooperate to strengthen the connection stability between the support rod 2 and the ground, which is beneficial to ensuring the stability of the scaffolding body 1 during use.

[0021] A sliding cavity 22 and an installation cavity 23 are sequentially arranged from bottom to top at the lower end of the support rod 2. An active block 4 is arranged in the installation cavity 23. An installation port 3131 is arranged at the top of the reinforcement rod 313. The transmission component 32 includes a transmission unit 3211. The transmission unit 3211 includes an I-shaped block 32111 slidably engaged with the inner wall of the installation cavity 23, a transmission rod 32112 penetrating through the I-shaped block 32111 and rotatably connected, a driven bevel gear 32113 fixed to one end of the transmission rod 32112 and located in the installation cavity 23, a worm 32114 fixed to the other end of the transmission rod 32112 and located in the installation port 3131, and a worm gear 32115 fixedly sleeved on the connecting shaft 312 and located in the installation port 3131. The worm gear 32115 meshes with the worm 32114. The transmission component 32 further includes a driving unit 3212 for driving the synchronous rotation of a plurality of driven bevel gears 32113 in the same support rod 2.

[0022] Each support rod 2 is provided with a pair of slide grooves 24 connected to the receiving groove 21, and the two pairs of slide grooves 24 are respectively located on both sides of the receiving 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 installation cavity 23 and the receiving 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 an active bevel gear 32123 fixed to the upper end of the rotating shaft 32122 and meshing with the driven bevel gear 32113.

[0023] It is worth noting that: when it is necessary to adjust the reinforcement rod 313 to unfold from the accommodating groove 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.

[0024] The rotating shafts 32122 in the three groups of transmission components 32 outside the upper motor 32121 are directly connected to the corresponding top of the movable block 4 for rotation. The linkage component 33 includes an upper synchronous wheel 331 fixedly mounted on the rotating shaft 32122. Four upper synchronous wheels 331 are provided and 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 meshing with the upper synchronous wheels 331. A movable through hole 26 that is connected to the mounting cavity 23 and allows 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.

[0025] After the upper motor 32121 starts working, 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 improve the stability of the scaffolding during use. In this embodiment, the upper synchronous belt 332 descends in the active through hole 26 during the descent of the reinforcement assembly 31.

[0026] An L-shaped connecting rod 41 is fixed at the position corresponding to the connecting hole 25 on the top of the movable block 4. 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. A bottom block 5 is fixed at the lower end of each support rod 2. 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 on the top of one of the bottom blocks 5. The output end of the lower motor 51 is coaxial and fixed with the corresponding threaded rod 3412. The lower ends of the other three threaded rods 3412 are rotatably connected to their corresponding bottom blocks 5 respectively. The lifting assembly 34 also includes a linkage unit 342 for driving the four threaded rods 3412 to rotate synchronously.

[0027] When the lifting assembly 34 is used 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 with the rectangular sleeve 3411, the rectangular sleeve 3411 and the sliding cavity 22 slide together, 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 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 descend synchronously, so that the multiple reinforcement rods 313 cooperate and complete the reinforcement effect on the scaffolding support rod 2.

[0028] The linkage unit 342 includes a lower synchronous wheel 3421 fixedly mounted on the threaded rod 3412. Four lower synchronous wheels 3421 are provided and 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 meshing 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.

[0029] 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.

[0030] A protective cover 27 is fixed between two adjacent support rods 2, and the fixed end of the protective cover 27 ring is arranged around the movable through hole 26, and the upper synchronous belt 332 and the lower synchronous belt 3422 are both located in the protective cover 27. The protective cover 27 plays a good protective role on the upper synchronous belt 332 and the lower synchronous belt 3422, which not only enhances the safety of the upper synchronous belt 332 and the lower synchronous belt 3422 during movement, but also reduces the aging speed of the upper synchronous belt 332 and the lower synchronous belt 3422.

[0031] To ensure the aesthetics of the surface of the support rod 2, when the reinforcing rod 313 is folded into the receiving groove 21, the side of the reinforcing 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 reinforcing rod 313, the lower end of the reinforcing rod 313 is bent toward the side close to the axis of the support rod 2. To facilitate the smooth folding of the reinforcing rod 313 into the receiving groove 21, a clearance portion 28 is provided at the position corresponding to the lower end of the receiving groove 21 and the reinforcing rod 313.

[0032] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
