Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a scaffold for construction engineering. Background Art

[0002] Scaffolding is a temporary support structure widely used on construction sites. It is mainly used to support construction personnel, materials, equipment, etc. to ensure the safety and smooth progress of the construction process. Scaffolding is usually composed of steel pipes, fasteners, scaffolding boards and other components. It can be built into various shapes and heights according to construction needs.

[0003] The mobile scaffold is a temporary support structure commonly used on construction sites. It is easy to assemble and disassemble. It is mainly composed of a main frame, a cross frame, a cross brace, a scaffolding board, an adjustable base and casters. It can be flexibly moved and reassembled. Most mobile scaffolds are equipped with four main columns, and the casters at the lower ends of the main columns can be used to move the entire scaffold. The casters are also arranged at the lower ends of the main columns through studs and adjustment mechanisms. The level of the entire mobile scaffold can be adjusted by adjusting the studs to ensure the stability of the mobile scaffold. However, after the studs are adjusted vertically through the adjustment mechanism, the adjustment mechanism cannot be achieved. The limited fixation or the inability to achieve rapid limited fixation, such as the Chinese utility model patent disclosed with publication number CN2825825Y: mobile scaffolding casters. After the adjustment of the threaded tube, the adjusting nut in the application does not limit the axial movement of the adjusting nut and the threaded tube. As a result, when people operate on the scaffolding, the vibration generated causes the adjusting nut to rotate or the universal caster to deflect and drive the threaded tube to rotate, thereby causing the height of one side of the scaffolding to change, which can easily cause the horizontality of the scaffolding to change, thereby causing the center of gravity of the scaffolding to change and causing the scaffolding to be unstable.

[0030] like Figure 6-Figure 9 As shown, two limit plates 15 are fixedly installed on the inner side of the column 1, and a fixing ring 16 is fixedly installed on the lower outer side of the column 1. The two limit plates 15 are arranged inside the column 1 to limit the axial movement of the screw 5 to prevent the screw 5 from rotating automatically due to the rotation of the wheel frame 7 and the roller 8. A first embedded ring groove 17 is opened at the lower end of the fixed gear ring 9.

[0031] like Figure 3-Figure 9As shown, a rotation groove 18 is provided on the inner side of the adjusting tube 10, and the rotation groove 18 is rotatably installed on the fixed ring 16, that is, the adjusting tube 10 is rotatably installed on the lower end of the column 1 through the rotation groove 18, and a second embedded ring groove 19 is provided on the upper end of the movable gear ring 14, and a plurality of connecting plates 21 are fixedly installed on the lower end of the movable gear ring 14, and two connecting plates 21 form a group, and a limiting slide groove 22 is provided in the connecting plate 21, and the limiting slide groove 22 is inserted on the rotating shaft 12 near one side of one of the shaft seats 11. The column 1 located between the first embedded ring groove 17 and the second embedded ring groove 19 is also provided with a compression spring 20, and the upper end of the compression spring 20 abuts against the top of the first embedded ring groove 17, and the lower end of the compression spring 20 abuts against the bottom of the second embedded ring groove 19, with the help of the fixed gear ring 9 and The setting of the movable gear ring 14 can make the movable gear ring 14 move up and engage with the fixed gear ring 9 when the operating handle 13 is stored, thereby limiting the axial movement of the adjusting tube 10. A rubber block 23 is fixedly installed at one end of the operating handle 13, and two limiting plane grooves 24 are provided on the outside of the screw 5. The screw 5 is threadedly connected in the adjusting tube 10, and the screw 5 located above the adjusting tube 10 is inserted in the column 1, and the limiting plane groove 24 is fitted with one side of the corresponding limiting plate 15. Two limiting plane grooves 24 are provided on the outside of the screw 5, and cooperate with the limiting plate 15 in the column 1 to limit the axial movement of the screw 5, so that the screw 5 can be vertically moved through the threaded connection between the adjusting tube 10 and the screw 5, thereby adjusting the installation height of a single column 1.

[0032] It should be noted that the utility model is a scaffold for construction engineering. When adjusting the height of the column 1, the operating handle 13 can be directly held and rotated, so that the operating handle 13 cooperates with the rotating shaft 12 and the shaft seat 11 to drive the adjusting tube 10 to rotate, so that the rotating groove 18 inside the adjusting tube 10 rotates on the fixed ring 16, and the adjusting tube 10 can be rotated at the lower end of the column 1. Synchronously, the two rotating shafts 12 respectively drive the corresponding two connecting plates 21 to rotate, so that the multiple connecting plates 21 drive the movable gear ring 14 to rotate synchronously with the adjusting tube 10, and the adjusting tube 10 is also threadedly connected with the screw rod 5 when rotating, and the screw rod 5 is limited in axial movement due to the two limiting plane grooves 24 on the outside and the two limiting plates 15 on the inside of the column 1. Therefore, when the outer thread of the screw rod 5 rotates, the adjusting tube 10 can make the screw rod 5 move vertically in the column 1, so as to adjust the height of the screw rod 5 protruding from the column 1, thereby adjusting the height of the column 1. , and then the height of multiple columns 1 is adjusted to achieve the horizontal degree of use of the entire scaffolding. When the screw rod 5 is adjusted, one end of the two operating handles 13 can be rotated downward with the corresponding rotating shaft 12 as the axis, and the operating handle 13 is adjusted to a vertical posture. After the operating handle 13 is rotated and stored, the rubber block 23 at one end of the operating handle 13 squeezes and moves the movable gear ring 14 upward. As a result, the movable gear ring 14 drives the multiple connecting plates 21 at the lower end to move upward synchronously, and the limiting sliding groove 22 in the connecting plate 21 moves upward at one end of one of the rotating shafts 12. At the same time, the second embedded ring groove 19 in the movable gear ring 14 compresses the compression spring 20 into the first embedded ring groove 17, and makes the movable gear ring 14 and the fixed gear ring 9 engage with each other, thereby limiting the axial movement of the movable gear ring 14. As a result, the movable gear ring 14 limits the axial movement of the adjusting tube 10 through the cooperation of the connecting plate 21 with the rotating shaft 12 and the shaft seat 11, and the screw rod 5 after the height adjustment can be quickly limited.
