According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into vertical pole scaffolding, bridge scaffolding, door scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] A Chinese utility model patent with publication number CN212613608U discloses a multifunctional scaffold for building decoration, including a lifting plate, a moving device, and a lifting plate. The top of the moving device is fixedly connected to a column, and the top of the column is movably connected to a top roller through a rotating shaft. A first steel wire rope is wound around the top roller. The lifting plate is lifted and lowered by the first steel wire rope to adjust the height of the lifting plate. When in use, the servo motor can be used to drive the rope retractor to retract and release the first steel wire rope, so as to facilitate the adjustment of the height of the lifting plate.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the lifting plate of the above-mentioned device has no protective components, and the steel wire rope will be worn after long-term use. If it is not replaced or repaired in time, there is a risk of sudden disconnection of the steel wire rope during use. Once disconnected, the lifting plate will lose support and fall rapidly, which is very likely to cause injuries to users and pose a safety hazard. Utility Model Content

[0019] By adopting the above technical solution, a screw rod, a base plate and a handle are provided, and the screw rod is driven to move up and down by turning the handle, thereby driving the base plate to move up and down, so that the base plate can be adjusted in height according to the flatness of the ground.

[0020] To sum up, the utility model has the following beneficial effects: in this application, an outer frame, an inner frame, a driving assembly, a lifting plate, a linkage assembly, a card plate, a compression spring, and a first steel wire rope are set. The worker stands on the lifting plate and drives the inner frame to slide upward through the driving assembly.

DETAILED DESCRIPTION

[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; 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.

[0028] like Figure 1-5 As shown, the embodiment of the present application discloses a multifunctional building construction scaffold, including an outer frame 10, an inner frame 20, a lifting plate 40, a driving assembly 30, a linkage assembly 50, and a protection assembly 60. The inner frame 20 is vertically slidably arranged in the outer frame 10, so that the inner frame 20 can rise or fall relative to the outer frame 10. The lifting plate 40 is vertically slidably arranged in the inner frame 20, so that the lifting plate 40 can rise or fall relative to the inner frame 20. The driving assembly 30 is arranged at the bottom of the outer frame 10, and the linkage assembly 50 is arranged at the top of the inner frame 20. The staff stands on the lifting plate 40. When the driving assembly 30 drives the inner frame 20 to rise, the linkage assembly 50 drives the lifting plate 40 to rise and sends the staff to the working area. The protection assembly 60 is arranged at the bottom of the inner frame 20. When the driving assembly 30 fails, the protection assembly 60 prevents the lifting plate 40 from falling downward, thereby ensuring the safety of the personnel on the lifting plate 40.

[0029] Specifically, the outer frame 10 includes a bottom frame 12 and columns 13 vertically arranged at the four corners of the bottom frame 12, and the inner frame 20 includes a top frame 22 and four vertical rods 23 vertically arranged at the bottom corners of the top frame 22. Fixed blocks 24 are arranged on the side walls opposite to each other in the length direction of the lifting plate 40 at the lower part of the vertical rods 23, and rollers 25 are arranged on the fixed blocks 24. The wheel core of the roller 25 is located on a horizontal plane and perpendicular to the length direction of the lifting plate 40. The wheel surface of the roller 25 is in rolling contact with the side walls of the columns 13, and the side walls of the vertical rods 23 are in sliding contact with the side walls of the columns 13, thereby guiding the sliding direction of the inner frame 20, so that the inner frame 20 can rise or fall more smoothly. The lifting plate 40 is provided with two mounting blocks 41 cantilevered outward on both sides in the length direction thereof, and a rotating wheel 42 is provided at one end of the mounting block 41 away from the lifting plate 40, and the wheel core of the rotating wheel 42 is located on a horizontal plane and perpendicular to the length direction of the lifting plate 40, and the wheel surface of the rotating wheel 42 is in rolling contact with the side wall of the vertical rod 23, and the side wall of the mounting block 41 is in sliding contact with the side wall of the vertical rod 23, so as to guide the sliding direction of the lifting plate 40, so that the lifting plate 40 can rise or fall more smoothly.

[0030] The driving assembly 30 includes a take-up roller 33, a driving motor 34, a second pulley 35, a third pulley 36, a first steel wire rope 31, and a connecting rope 32. The take-up roller 33 is horizontally rotatably arranged on the bottom frame 12, and the driving motor 34 is arranged on the bottom frame 12 to drive the take-up roller 33 to rotate. There are two second pulleys 35, which are arranged on both sides of the bottom of the bottom frame 12, and there are two third pulleys 36, which are arranged on the top of the outer frame 10 and directly above the second pulley 35, so as to ensure that the first steel wire rope 31 moves smoothly when the first steel wire rope 31 is pulled. The roller core of the take-up roller 33, the wheel core of the second pulley 35 and the wheel core of the third pulley 36 are all parallel, and the side of the take-up roller 33, the side of the second pulley 35 and the side of the third pulley 36 are coplanar. One end of the first steel wire rope 31 is wound around the take-up roller 33, and the other end is connected to two connecting ropes 32 after passing through the second pulley 35 and the third pulley 36 in sequence.

[0031] The linkage assembly 50 includes a second steel wire rope 51 and four first pulleys 52 arranged on both sides of the top of the top frame 22. One end of the second steel wire rope 51 is connected to the top of the outer frame 10, and the other end is connected to the lifting plate 40 after passing around the upper part of the first pulley 52. ​​When the inner frame 20 rises, the first pulley 52 is driven to rise. Since one end of the second steel wire rope 51 is connected to the top of the outer frame 10, the other end of the second steel wire rope 51 pulls the lifting plate 40 to slide upward.

[0032] There are two groups of protection components 60, which are respectively arranged on both sides of the bottom of the inner frame 20. The protection components 60 include a mounting plate 61 arranged at intervals at the bottom of the inner frame 20, and a clamping plate 62 is hingedly arranged on the mounting plate 61 so that the clamping plate 62 can rotate. The clamping plate 62 is Z-shaped as a whole, and a plurality of clamping grooves 14 are vertically spaced apart on one side of the column 13 adjacent to the clamping plate 62. When the clamping plate 62 is matched with the clamping groove 14, the clamping plate 62 is fixed so that the inner frame 20 is fixed. A compression spring 63 is arranged between the end of the clamping plate 62 away from the column 13 and the bottom of the inner frame 20. A through hole 21 is vertically opened at the bottom of the inner frame 20 corresponding to the compression spring 63. The diameter of the through hole 21 is smaller than the inner diameter of the compression spring 63. The two connecting ropes 32 pass through the two through holes 21 and the middle of the compression spring 63 respectively and are connected to the corresponding clamping plate 62. The drive motor 34 drives the wire-taking roller 33 to rotate, thereby winding or releasing the first steel wire rope 31 onto the wire-taking roller 33, so that the first steel wire rope 31 and the connecting rope 32 pull the inner frame 20 to rise or fall. Under normal circumstances, the compression spring 63 is compressed under the action of the first steel wire rope 31 pulling the end of the card plate 62 away from the column 13 upward and the self-weight of the inner frame 20. At this time, the card plate 62 is away from the slot, and the inner frame 20 and the lifting plate 40 can be raised and lowered; after a long period of use, when the first steel wire rope 31 breaks due to wear, the compression spring 63 loses its constraint, thereby extending and pushing the card plate 62 to rotate, so that the end of the card plate 62 close to the column 13 is stuck in the slot, fixing the inner frame 20 and the lifting plate 40, and preventing the lifting plate 40 from falling and injuring the staff.

[0033] Since the second steel wire rope 51 has fewer bends, the risk of it being damaged is relatively low. Based on this consideration, the protection component 60 is not configured on the lifting plate 40. However, in order to further improve the safety performance of the entire device, the protection component 60 can still be added to the lifting plate 40 to further improve the stability and safety of the scaffold.

[0034] In the specific configuration, a hinge shaft 15 is vertically arranged on the outer side of the bottom frame 12, and a support arm 16 is hingedly arranged on the bottom frame 12 through the hinge shaft 15. A support leg 17 is arranged at one end of the support arm 16 away from the hinge shaft 15. The support arm 16 is unfolded, and the support leg 17 is used to support the outer frame 10, thereby ensuring the stability of the outer frame 10. The support leg 17 includes a screw rod 171 vertically spiraled on the support arm 16, a bottom plate 172 is rotatably arranged at the lower end of the screw rod 171, and a handle 173 is arranged at the upper end. The screw rod 171 is driven to move up and down by rotating the handle 173, thereby driving the bottom plate 172 to move up and down, so that the bottom plate 172 can adjust the height according to the different flatness of the ground.

[0035] The use principle of a multifunctional building construction scaffold in this embodiment is as follows: a worker stands on the lifting plate 40 and starts the drive motor 34. The drive motor 34 drives the take-up roller 33 to rotate, and winds the first steel wire rope 31 onto the take-up roller 33, so that the first steel wire rope 31 and the connecting rope 32 pull the inner frame 20 to rise, thereby driving the lifting plate 40 to slide upward and sending the worker to the work area; after a long period of use, when the first steel wire rope 31 breaks due to wear, the compression spring 63 loses its constraint, thereby extending and pushing the card plate 62 to rotate, so that the end of the card plate 62 near the column 13 is stuck in the card slot, and the inner frame 20 and the lifting plate 40 are fixed to prevent the lifting plate 40 from falling and injuring the worker.

[0036] The above is only a preferred embodiment of the present invention. 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.
