Description

Technical Field

[0001] The invention relates to the technical field of scaffolds, in particular to an adjustable scaffold for construction and installation. Background Art

[0002] Adjustable scaffolding is a common type of support equipment used in construction, widely used for high-altitude work on buildings. Its primary function is to provide stable support, ensuring that workers can safely perform various construction operations. Scaffolding, which can be raised or lowered to adjust its height, is commonly used in high-altitude workplaces, providing flexible support and safety. It is widely used in construction, renovation, and maintenance projects. Its design allows operators to adjust the scaffolding's height as needed, facilitating construction operations at different heights. Proper use of adjustable scaffolding can effectively improve work efficiency and ensure safety and stability during construction.

[0003] Patent No. CN222686071U discloses an adjustable scaffold for construction, comprising a scaffold body, an adjustment mechanism provided on one side surface of the scaffold body, a protective mechanism provided on one side surface of the scaffold body, and a standing board installed on one side surface of the scaffold body. The adjustable scaffold for construction, through the arrangement of an adjustment frame, an adjustment knob, a slot, a threaded rod, and a base, enables the scaffold body to be height-adjusted according to construction requirements during use. By rotating the adjustment knob, the threaded rod can be driven to move in the threaded groove inside the adjustment frame, thereby causing the base to be raised or lowered, thereby facilitating construction at different heights, improving construction efficiency, and enhancing construction safety. However, this patent still has the problem of being inconvenient to adjust the height or position according to the construction progress and being inconvenient to disassemble. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides an adjustable scaffold for construction and installation, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an adjustable scaffold for construction and installation, comprising a base frame, a protective shell provided in the middle inner portion of the base frame, a self-locking motor provided on the front side of the protective shell, four universal wheels provided on the bottom side of the base frame, and two folding locking mechanisms provided above the protective shell;

[0006] The folding locking mechanism includes four supporting side arms, and the four supporting side arms are hingedly connected to the front and rear sides of the base frame in groups of two. The side surfaces of each supporting side arm are provided with an inner slide groove, the inner side of the inner slide groove is slidably connected to a push rod, the middle of the push rod is rotatably connected to the diagonal support rod, the inner sides of the left and right ends of the base frame are fixedly connected to the hinge shaft seats, the outer side of the end of the hinge shaft seat away from the base frame is rotatably connected to the hinge shaft block, the end of the hinge shaft block away from the hinge shaft seat is fixedly connected to the support frame, the upper surface of the hinge shaft block is fixedly connected to the hinge connecting rod, the upper surfaces of the left and right ends of the base frame are fixedly connected to the retracting rod blocks, and the front and rear ends of the retracting rod block are slidably connected to the connecting block rod.

[0007] According to the above technical solution, a safety locking mechanism is provided above each of the folding locking mechanisms, and a protective storage mechanism is provided between the two safety locking mechanisms. The output shaft of the self-locking motor is fixedly connected to a cable winding roller, and a steel cable is wound around the outer side of the cable winding roller. The end of the connecting rod away from the rod receiving block is fixedly connected to the limiting block, the inner side of the bottom end of the support frame is fixedly connected to the limiting block bar, the end of the support side arm away from the base frame is threadedly connected to a threaded support rod, and the top of the threaded support rod is fixedly connected to a support rod knob.

[0008] The cam is fixed to the chassis and the rear frame is fixed with the cam, and the self-locking motor is installed in the middle of the front side of the chassis. The hinge block on the right side is twice the length of the hinge block on the left side. The hinge connecting rod is rotatably connected to the diagonal support rod. A contraction spring is provided inside the connecting rod, and the middle part of the contraction spring is fixed to the inner wall of the retracting rod block, and the front and rear ends of the contraction spring are fixedly connected to the two connecting rods respectively. When the support frame is folded and unfolded, the support frame is manually flipped over, and when the support frame is flipped, the hinge block fixed on the support frame flips and rotates around the connected hinge seat. During the flipping process, the bottom of the support frame applies pressure to the inclined surface of the limit block through the limit block bar, so that the inclined surface of the limit block is forced to push the connecting rod to extend outward from the inside of the retracting rod block and pull the contraction spring to deform under pressure. When the limit block fits the side of the support frame and is no longer blocked by the limit block bar, the internal contraction spring of the retracting rod block pulls the connecting block rod to retract into the retracting rod block through elastic reset. During the above movement, the connecting block rod pulls the limit block to fit the limit block bar and slides to the bottom end of the support frame. At this time, the support frames on both sides are kept perpendicular to the horizontal plane of the base frame by flipping, which quickly locks the support frame. At the same time, when the support frame is flipped by the fixed hinge block, the hinge connecting rod connected to the hinge block will pull the diagonal support rod to move with the flip. The movement of the diagonal support rod pulls the push rod to move and slide along the inner slide groove of the connected support side arms on both sides. The push rod slides in the inner slide groove to make the support side arms quickly unfold around the connection of the base frame, and then the threaded support rod is adjusted by turning the support rod knob to extend downward along the connection of the support side arm to contact the ground.

[0009] According to the above technical solution, the safety locking mechanism includes a lifting frame, which is slidably connected to the inner side of the supporting side arm, and the inner side of the lifting frame is slidably connected to the lifting end, the top and bottom side surfaces of the supporting side arm are fixedly connected to the wheel seat plate, and two seat plate guide wheels are installed on each side of the wheel seat plate, the inner side of the bottom end of the lifting frame is rotatably connected to the frame bottom guide wheel, two bottom guide wheels are installed on the bottom end side of the lifting frame, and two top guide wheels are installed on the top of the lifting frame, and a metal bar is provided above each lifting end, the middle part of the metal bar is fixedly connected to a connecting rod, and the end of the connecting rod away from the metal bar is fixedly connected to an elastic sheet.

[0010] According to the above technical solution, both ends of the bottom side of the elastic sheet are hingedly connected to a locking rod, and the front and rear inner side surfaces of the lifting frame are provided with a plurality of equidistantly distributed locking grooves. The front and rear ends of the lifting frame are slidably connected to long slide bars, and the upper and lower ends of the long slide bars are slidably connected to long limit blocks. The bottom end side surface of each long slide bar is fixedly connected to a handle rod, and the bottom ends of the front and rear sides of the lifting frame are rotatably connected to a tooth handle.

[0011] According to the above technical solution, two vertical guide rods are fixedly connected to the inner side of the lifting frame, and the vertical guide rods are slidably connected to the lifting end, the metal strip is fixedly connected to the steel cable, and the top of the steel cable is fixedly connected to the lifting end. The two blocking rods are slidably passed through the interior of the lifting end, the long limit block is fixedly connected to the lifting frame, and the inner side surface of the supporting side arm in contact with the lifting frame is provided with equidistantly distributed blocking teeth, and a spring sheet is provided inside the lifting frame, and the two ends of the spring sheet are respectively connected to the lifting frame and The long slide is fixedly connected, and the top of the steel cable is fixed on the lifting end. The steel cable passes over the top guide wheel on the top of the lifting frame from the top of the lifting end and is led downward to the bottom guide wheel installed on the lifting frame. The bottom guide wheel passes over the bottom guide wheel of the frame and is led to the seat plate guide wheel on the top of the supporting side arm and then passes over the seat plate guide wheel to the seat plate guide wheel at the bottom end of the supporting side arm. The steel cable passes over the seat plate guide wheel at the bottom end of the supporting side arm and is led to the cable roller for winding. When the self-locking motor is in working state to wind up the steel cables on the left and right sides, the cable roller rotates counterclockwise. The left steel cable is wound from above the cable roller, and the right steel cable is wound from below the cable roller. When the cable roller is wound, the steel cable is pulled around the bottom guide wheel and the bottom side guide wheel at the bottom of the lifting frame, and the seat plate guide wheel above the supporting side arm is used as a fixed pulley, so that the lifting frame is lifted up and slides upward along the supporting side arm. At the same time, the steel cable that passes around the bottom guide wheel passes around the top guide wheel, and uses the top guide wheel as a fixed pulley to pull the lifting end upward, so that the lifting end slides upward along the vertical slide rod inside the lifting frame to achieve lifting. When the steel cable appears When it breaks, the steel cable cannot maintain its tension, and the metal bar loses the traction of the steel cable, which will cause the elastic sheet to recover its deformation. The elastic sheet that recovers its deformation pushes the connected locking rods on both sides to pass through the locking slots of the lifting frame, so that the lifting end and the lifting frame are relatively stationary. Then, the locking rod passes through the locking slots to push the long slider, so that the long slider slides along the long slider limit block and squeezes the spring sheet. The movement of the long slider limit block drives the connected dial handle rod, so that the dial handle rod pushes the protrusion of the tooth handle to rotate and get stuck on the locking tooth in the supporting side arm.

[0012] According to the above technical solution, the protective storage mechanism includes a platform cross frame, the upper part of the platform cross frame is fixedly connected to a platform plate, the front and rear sides of the platform cross frame are provided with plate-through grooves, the front and rear ends of the platform cross frame are slidably connected with two short hinge rods, the ends of the short hinge rods are hingedly connected to railings, the sides of the railings are fixedly connected with blocking plates, the inner bottom end of the railing is provided with a spring groove, the inner side of the spring groove is slidably connected with a spring block, the bottom surface of the spring block is fixedly connected to an elastic rod, and the side of the spring block is fixedly connected to a shift rod.

[0013] According to the above technical solution, the push rod is slidably connected to the railing, and the push rod passes through the outer surface of the railing from the inner side of the spring groove. The end of the short hinge rod is provided with a block, and the upper side of the block is provided with a locking hole for cooperating with the elastic rod. The inside of the spring groove is provided with an elastic spring, and the two ends of the elastic spring are fixedly connected to the spring block and the railing respectively. When in the storage state, the short hinge rod and the railing remain horizontal, and the elastic spring is used to push the push rod connected to the spring block to be stuck in the square at the end of the short hinge rod. The blocking plate connected to the railing is stored in the bottom surface of the platform plate through the through-plate groove starting from the side of the platform cross frame. At the same time, the length of the railing on the rear side is smaller than the railing on the front side, so that the front and rear railings are staggered when stored. When the platform frame is lowered to near the ground, the railing is flipped so that the edge of the railing is placed on the supporting side arm, and the blocking plate is used as a ramp pedal to assist in transporting materials or workers walking. When the scaffolding as a whole needs to be stored, the platform frame is placed on one end of the lifting end with a hook-shaped structure and stowed, so that the platform frame is flipped around the other hinged lifting end to achieve storage.

[0014] The present invention provides an adjustable scaffold for construction and installation, which has the following beneficial effects:

[0015] The present invention provides a stable support structure by providing a folding and locking mechanism. The stable support structure can evenly distribute the load and prevent tilting or collapse caused by local overload. At the same time, the scaffolding with good stability can maintain its integrity at high altitudes or in severe weather such as strong winds and vibrations, reducing accidents. In addition, the foldable scaffolding does not need to be assembled one by one, and can be locked directly after being unfolded, reducing construction time. During installation, the scaffolding automatically locks in place through the snap-fit ​​structure, avoiding the risk of loosening caused by untightened bolts.

[0016] The present invention is equipped with a safety locking mechanism, which allows the lifting frame and the lifting end to be raised and lowered synchronously by winding the steel cable, thereby increasing the lifting speed and the rising height. When masonry construction, curtain wall installation, and other operations are carried out simultaneously on different floors, the scaffolding height can be adjusted to match the construction progress, thereby improving construction efficiency. In addition, compared with traditional scaffolding without self-locking, the structural locking prevents the lifting frame and the lifting end from continuing to fall, which can completely avoid the risk of falling from a high altitude, ensure the safety of workers and people below, and improve safety.

[0017] The present invention is provided with a protective storage mechanism. By flipping the railing, the railing can be quickly folded up, reducing the occupied space and facilitating the movement or storage of the scaffold in a narrow area. At the same time, the railing can be laid flat to form a sloped passage, which is convenient for carrying carts, small equipment or building materials and increases the safety during the rising process of the platform cross frame.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figures 1-9 One embodiment of the present invention is: an adjustable scaffold for construction and installation, comprising a base frame 1, a protective shell 2 provided in the middle of the inner side of the base frame 1, a self-locking motor 3 provided on the front side of the protective shell 2, four universal wheels 4 provided on the bottom side of the base frame 1, and two folding locking mechanisms 5 provided above the protective shell 2;

[0030] The folding locking mechanism 5 includes four supporting side arms 51, and the four supporting side arms 51 are hingedly connected to the front and rear sides of the base frame 1 in groups of two. An inner sliding groove 52 is provided on the side of each supporting side arm 51, and a push rod 53 is slidably connected to the inner side of the inner sliding groove 52. The middle part of the push rod 53 is rotatably connected to the diagonal support rod 54. The inner sides of the left and right ends of the base frame 1 are fixedly connected to a hinge seat 55, and the outer side of the end of the hinge seat 55 away from the base frame 1 is rotatably connected to a hinge block 56. The end of the hinge block 56 away from the hinge seat 55 is fixedly connected to a support frame 57, and the upper surface of the hinge block 56 is fixedly connected to a hinge connecting rod 58. The upper surfaces of the left and right ends of the base frame 1 are fixedly connected to a retracting rod block 59, and the front and rear ends of the retracting rod block 59 are slidably connected to a connecting block rod 510.

[0031] A safety locking mechanism 6 is provided above each folding locking mechanism 5, and a protective storage mechanism 7 is provided between the two safety locking mechanisms 6. The output shaft of the self-locking motor 3 is fixedly connected to the cable winding roller 8, and a steel cable 9 is wound around the outer side of the cable winding roller 8. The end of the connecting rod 510 away from the rod receiving block 59 is fixedly connected to the limiting block 511, and the inner side of the bottom end of the support frame 57 is fixedly connected to the limiting block bar 512. The end of the supporting side arm 51 away from the base frame 1 is threadedly connected to the threaded support rod 514, and the top of the threaded support rod 514 is fixedly connected to the support rod knob 513.

[0032] The rear end of the protective shell 2 is fixedly connected to the base frame 1, and the self-locking motor 3 is installed in the middle of the front side of the base frame 1. The hinge block 56 on the right is twice the length of the hinge block 56 on the left. The hinge rod 58 is rotatably connected to the diagonal support rod 54. A contraction spring is provided inside the connecting rod 510, and the middle part of the contraction spring is fixed to the inner wall of the receiving rod block 59, and the front and rear ends of the contraction spring are respectively fixedly connected to the two connecting rods 510. When the support frame 57 is folded and unfolded, the support frame 57 is manually flipped over to rotate the hinge shaft fixed to the support frame 57. The block 56 flips and rotates around the connected hinge seat 55. During the flipping process, the bottom of the support frame 57 applies pressure to the inclined surface of the limit block 511 through the limit block bar 512, so that the inclined surface of the limit block 511 is forced to push the connecting rod 510 to extend outward from the inside of the retracting rod block 59 and pull the contraction spring to deform under pressure. When the limit block 511 fits the side of the support frame 57 and is no longer blocked by the limit block bar 512, the contraction spring inside the retracting rod block 59 is reset by elastic force to pull the connecting rod 510 to retract into the retracting rod block 59. During the above movement, the connecting rod 510 pulls the limit block 511 to fit When the limit block bar 512 slides to the bottom end of the support frame 57, the support frames 57 on both sides are kept perpendicular to the horizontal plane of the base frame 1 by flipping, which plays a role in quickly locking the support frame 57. At the same time, when the support frame 57 is flipped by the fixed hinge block 56, the hinge connecting rod 58 connected to the hinge block 56 will pull the diagonal support rod 54 to move with the flip, and the diagonal support rod 54 will pull the push rod 53 to move and slide along the inner groove 52 of the supporting side arms 51 on both sides. The push rod 53 slides in the inner groove 52 to make the supporting side arms 51 quickly unfold around the connection of the base frame 1, and then pass By turning the strut knob 513 to adjust the threaded strut 514, it extends downward along the connection of the supporting side arm 51 and contacts the ground, providing a stable support structure. The stable support structure can evenly distribute the load and prevent tilting or collapse caused by local overload. At the same time, at high altitudes or in severe weather such as strong winds and vibrations, a scaffold with good stability can maintain its integrity and reduce accidents. In addition, the foldable scaffold does not need to be assembled one by one, and can be locked directly after it is unfolded, reducing the construction time. During installation, it is automatically locked in place through the snap-fit ​​structure to avoid the risk of loosening caused by untightened bolts.

[0033] The safety locking mechanism 6 includes a lifting frame 61, which is slidably connected to the inner side of the supporting side arm 51. The inner side of the lifting frame 61 is slidably connected to the lifting end 62. The top and bottom sides of the supporting side arm 51 are fixedly connected to the wheel seat plate 63. Two seat plate guide wheels 64 are installed on the side of each wheel seat plate 63. The bottom inner side of the lifting frame 61 is rotatably connected to the frame bottom guide wheel 65. Two bottom side guide wheels 66 are installed on the bottom side of the lifting frame 61. Two top guide wheels 67 are installed on the top of the lifting frame 61. A metal bar 68 is provided above each lifting end 62. A connecting rod 69 is fixedly connected to the middle of the metal bar 68. An elastic sheet 610 is fixedly connected to the end of the connecting rod 69 away from the metal bar 68.

[0034] Both ends of the bottom side of the elastic sheet 610 are hingedly connected to a locking rod 611, and the front and rear inner side surfaces of the lifting frame 61 are provided with a plurality of equally spaced locking grooves 612. The front and rear ends of the lifting frame 61 are slidably connected to the inside of the long slide 613, and the upper and lower ends of the long slide 613 are slidably connected to the long limit block 614. The bottom side of each long slide 613 is fixedly connected to a handle rod 615, and the bottom of the front and rear sides of the lifting frame 61 is rotatably connected to a tooth handle 616.

[0035] Two vertical guide rods are fixedly connected to the inner side of the lifting frame 61, and the vertical guide rods are slidably connected to the lifting end 62, the metal strip 68 is fixedly connected to the steel cable 9, and the top of the steel cable 9 is fixedly connected to the lifting end 62. The two positioning rods 611 slide through the inside of the lifting end 62, the long limit block 614 is fixedly connected to the lifting frame 61, and the inner side surface of the supporting side arm 51 in contact with the lifting frame 61 is provided with equidistantly distributed positioning teeth. A spring sheet is provided inside the lifting frame 61, and the two ends of the spring sheet are fixedly connected to the lifting frame 61 and the long slide bar 613 respectively. The top of the steel cable 9 is fixed on the lifting end 62, and the steel cable 9 passes over the top guide wheel 67 at the top of the lifting frame 61 from above the lifting end 62 and is led downward to the bottom of the lifting frame 61. When the cable roller 8 is wound, the steel cable 9 is pulled around the bottom guide wheel 65 and the bottom guide wheel 66 at the bottom of the lifting frame 61 and the seat plate guide wheel 64 above the supporting side arm 51 is used as a fixed pulley to make the lifting frame 61 be lifted and lowered. The lowering frame 61 is lifted up and slides upward along the supporting side arm 51. At the same time, the steel cable 9 passes around the bottom guide wheel 65 and around the top guide wheel 67, and uses the top guide wheel 67 as a fixed pulley to pull the lifting end 62 upward, so that the lifting end 62 slides upward along the vertical slide rod in the lifting frame 61 to achieve lifting. When the steel cable 9 breaks, the steel cable 9 cannot maintain the taut state. The metal strip 68 loses the traction of the steel cable 9, which will allow the elastic sheet 610 to restore its deformation. The elastic sheet 610 that restores its deformation pushes the connected two-side blocking rods 611 to pass through the blocking groove 612 of the lifting frame 61, so that the lifting end 62 and the lifting frame 61 are relatively stationary. Subsequently, the blocking rod 611 passes through the blocking groove 612 and pushes the long slide bar 613, so that the long The slide bar 613 slides along the long limit block 614 and squeezes the spring sheet, and the movement of the long limit block 614 drives the connected dial handle rod 615, so that the dial handle rod 615 pushes the protrusion of the latch handle 616 to rotate and latch on the latch tooth in the supporting side arm 51. The steel cable 9 is wound to make the lifting frame 61 and the lifting end 62 rise and fall synchronously, thereby improving the lifting speed and increasing the rising height. When masonry, curtain wall installation and other operations are carried out on different floors at the same time, the scaffolding height can be adjusted to match the construction progress and improve construction efficiency. In addition, compared with traditional scaffolding without self-locking, the structural locking prevents the lifting frame 61 and the lifting end 62 from continuing to fall, which can completely avoid the risk of falling from high altitude, ensure the safety of workers and people below, and improve safety.

[0036] The protective storage mechanism 7 includes a platform cross frame 71, which is fixedly connected to a platform plate 72 on the upper side of the platform cross frame 71, and plate-through grooves 73 are provided on the front and rear sides of the platform cross frame 71. The front and rear ends of the platform cross frame 71 are slidably connected to two short hinge rods 74, and the ends of the short hinge rods 74 are hingedly connected to railings 75. The sides of the railings 75 are fixedly connected to blocking plates 76. The inner bottom end of the railings 75 is provided with a spring groove 77, and the inner side of the spring groove 77 is slidably connected to a spring block 78. The bottom surface of the spring block 78 is fixedly connected to an elastic rod 710, and the side of the spring block 78 is fixedly connected to a shift rod 79.

[0037] The lever 79 is slidably connected to the railing 75. The lever 79 passes through the outer surface of the railing 75 from the inner side of the spring groove 77. The end of the short hinge rod 74 is provided with a block, and the upper side of the block is provided with a positioning hole for matching the elastic rod 710. The spring groove 77 is provided with an elastic spring, and the two ends of the elastic spring are fixedly connected to the elastic block 78 and the railing 75 respectively. When in the storage state, the short hinge rod 74 and the railing 75 remain horizontal, and the elastic spring is used to push the elastic block. The lever 79 connected to 78 is stuck in the end block of the short hinge rod 74, and the blocking plate 76 connected to the railing 75 is stored on the bottom surface of the platform plate 72 through the through-plate groove 73 starting from the side of the platform cross frame 71. At the same time, the railing 75 at the rear side is shorter than the railing 75 at the front side, so that the front and rear railings 75 are staggered when stored. In addition, when the blocking plates 76 connected to the two railings 75 are stored, the two blocking plates 76 are attached to each other in the storage state and stored in an upper and lower staggered manner. When the railing 75 is raised or lowered on the platform cross frame 71, the railing 75 is pulled out from the side of the platform cross frame 71, and the railing 75 is flipped over to keep it perpendicular to the short hinge rod 74. At this time, the elastic spring pushes the lever 79 connected to the spring block 78 to be stuck in the end block of the short hinge rod 74, so that the railing 75 plays a protective role. When the platform cross frame 71 is lowered close to the ground, the railing 75 is flipped over so that the edge of the railing 75 rests on the supporting side arm 51, and the blocking plate 76 is used as a ramp step. To assist in transporting materials or workers walking, when the scaffolding as a whole needs to be stored, the platform cross frame 71 is placed on one end of the lifting end 62 with a hook-shaped structure and folded up, so that the platform cross frame 71 is flipped around the other hinged lifting end 62 to achieve storage. By flipping the railing 75, the railing 75 can be quickly folded up to reduce the occupied space, making it easier for the scaffolding to be moved or stored in a narrow area. At the same time, the railing 75 can be laid flat to form a sloped passage, which is convenient for the transportation of carts, small equipment or building materials.

[0038] When the support frame 57 is folded and unfolded, the support frame 57 is manually flipped over to allow the support frame 57 to flip over, and the hinge block 56 fixed to the support frame 57 flips and rotates around the connected hinge seat 55. During the flipping process, the bottom of the support frame 57 applies pressure to the inclined surface of the limit block 511 through the limit block bar 512, so that the inclined surface of the limit block 511 is forced to push the connecting rod 510 to extend outward from the inside of the retracting rod block 59 and pull the contraction spring to deform under pressure. When the limit block 511 is in contact with the side of the support frame 57 and is no longer blocked by the limit block bar 512, the contraction spring inside the retracting rod block 59 is reset by elastic force and pulls the connecting rod 510 to retract into the retracting rod block 59. During the above movement, the connecting rod 510 pulls the limit block 511 to fit the limit block bar 512 and slide to the bottom end of the support frame 57. At this time, the support frames 57 on the left and right sides are kept perpendicular to the horizontal plane of the base frame 1 by flipping, which plays a role in quickly locking the support frame 57. When the support frame 57 is turned over by the fixed hinge block 56, the hinge connecting rod 58 connected to the hinge block 56 will pull the diagonal support rod 54 to move with the turning, and the movement of the diagonal support rod 54 will pull the push rod 53 to move and slide along the inner slide groove 52 of the supporting side arms 51 connected on both sides. The push rod 53 slides in the inner slide groove 52 to allow the supporting side arms 51 to quickly unfold around the connection of the base frame 1, and then the threaded support rod 514 is adjusted by turning the support rod knob 513 to extend downward along the connection of the supporting side arms 51 to contact the ground, providing a stable support structure. The stable support structure can evenly distribute the load and prevent tilting or collapse caused by local overload. At the same time, at high altitude or in bad weather such as strong wind and vibration, the scaffold with good stability can maintain its integrity and reduce accidents. In addition, the foldable scaffold does not need to be assembled one by one, and can be locked directly after it is unfolded, which reduces the construction time. During installation, it is automatically locked after it is in place through the snap-fit ​​structure to avoid the risk of loosening caused by untightened bolts.

[0039] The top of the steel cable 9 is fixed on the lifting end 62. The steel cable 9 passes over the top guide wheel 67 on the top of the lifting frame 61 from the top of the lifting end 62 and is led downward to the bottom guide wheel 66 installed on the lifting frame 61. The bottom guide wheel 66 passes over the bottom guide wheel 65 of the frame and is led to the seat plate guide wheel 64 at the top of the supporting side arm 51 and passes over the seat plate guide wheel 64 to be led to the seat plate guide wheel 64 at the bottom end of the supporting side arm 51. The steel cable 9 passes over the seat plate guide wheel 64 at the bottom end of the supporting side arm 51 and is led to the cable roller 8 for winding. When the self-locking motor 3 is in the working state to wind up the steel cables 9 on the left and right sides, the cable roller 8 rotates counterclockwise. The needle rotates, and the left steel cable 9 is wound from above the cable roller 8, and the right steel cable 9 is wound from below the cable roller 8. When the cable roller 8 is wound, the steel cable 9 is pulled around the bottom guide wheel 65 and the bottom side guide wheel 66 at the bottom of the lifting frame 61, and the seat plate guide wheel 64 above the supporting side arm 51 is used as a fixed pulley, so that the lifting frame 61 is lifted up and slides upward along the supporting side arm 51. At the same time, the steel cable 9 that passes around the bottom guide wheel 65 passes around the top guide wheel 67, and uses the top guide wheel 67 as a fixed pulley to pull the lifting end 62 upward, so that the lifting end 62 slides upward along the vertical slide rod inside the lifting frame 61. To achieve lifting, when the steel cable 9 breaks, the steel cable 9 cannot maintain its tension. The metal strip 68 loses the traction of the steel cable 9, which causes the elastic sheet 610 to recover its deformation. The elastic sheet 610 that recovers its deformation pushes the connected two-side locking rods 611 through the locking grooves 612 of the lifting frame 61, so that the lifting end 62 and the lifting frame 61 are relatively stationary. Subsequently, the locking rods 611 pass through the locking grooves 612 and push the long slide 613, so that the long slide 613 slides along the long limit block 614 and squeezes the spring sheet, which moves through the long limit block 614 to drive the connected handle rod 615 , so that the handle rod 615 pushes the protrusion of the latch handle 616 to rotate and latch on the latching tooth in the supporting side arm 51, and the lifting frame 61 and the lifting end 62 are lifted and lowered synchronously by winding the steel cable 9, thereby improving the lifting speed and increasing the lifting height. When masonry, curtain wall installation and other operations are carried out on different floors at the same time, the scaffolding height can be adjusted to match the construction progress and improve construction efficiency. In addition, compared with traditional scaffolding without self-locking, the structural locking prevents the lifting frame 61 and the lifting end 62 from continuing to fall, which can completely avoid the risk of falling from a high altitude, ensure the safety of workers and people below, and improve safety.

[0040] When the platform cross frame 71 is lifted, the short hinge rod 74 and the railing 75 remain horizontal, and the elastic spring pushes the lever 79 connected to the spring block 78 to be stuck in the square at the end of the short hinge rod 74, and the blocking plate 76 connected to the railing 75 is stored in the bottom surface of the platform plate 72 through the through-plate groove 73 starting from the side of the platform cross frame 71. At the same time, the railing 75 at the rear side is shorter than the railing 75 at the front side, allowing the front and rear railings 75 to be staggered when stored. In addition, when the blocking plates 76 connected to the two railings 75 are stored, the two blocking plates 76 are attached to each other in the storage state and stored in an upper and lower staggered manner. When the railing 75 is raised and lowered on the platform cross frame 71, the railing 75 is pulled out from the side of the platform cross frame 71, allowing the railing 75 to flip and remain perpendicular to the short hinge rod 74. At this time, the elastic spring pushes The lever 79 connected to the movable block 78 is stuck in the end block of the short hinge rod 74, allowing the railing 75 to play a protective role. When the platform cross frame 71 is lowered close to the ground, the railing 75 is flipped so that the edge of the railing 75 is placed on the supporting side arm 51, and the blocking plate 76 is used as a ramp pedal to assist in transporting materials or workers walking. When the scaffolding as a whole needs to be stored, the platform cross frame 71 is placed on one end of the lifting end 62 with a hook structure and folded up, so that the platform cross frame 71 is flipped around the other hinged lifting end 62 to achieve storage. By flipping the railing 75, the railing 75 can be quickly folded up, reducing the space occupied, making it easier for the scaffolding to be moved or stored in a narrow area. At the same time, the railing 75 can be laid flat to form a ramp channel, which is convenient for the transportation of carts, small equipment or building materials.
