second embodiment

Referring to Fig. 5 and Fig. 6, based on the supporting structure of a building scaffold provided in the first embodiment, its levelness needs to be detected after the location is selected, so as to ensure that the scaffold at the top is in a horizontal and stable state, and the scaffold that is too high will not It is convenient for construction personnel to climb to the top of the standing board 3, and there are no supporting parts when the construction personnel reach the top of the standing board 3, thereby reducing the safety factor of the construction, and it is inconvenient for the construction personnel to place and store the construction objects. In order to solve the above problems, improve The levelness of the scaffold and the ease of operation, the construction scaffold support structure also includes: one side of the support rod 201 is provided with a first fixed block 19, and the inner rotation of two adjacent first fixed blocks 19 is connected with a first rotating shaft 20 , the first rotating shaft 20 is symmetrically distributed on both sides of the entire scaffold, so that the symmetrical distribution can ensure the stability of fixing and installation. The outer surface of the first rotating shaft 20 is symmetrically provided with two sets of first vertical bars 21, the first vertical bars 21 One side of the first torsion spring 25 is provided, the other side of the first torsion spring 25 is fixedly connected with one side of the first fixed block 19, and the side of the first vertical bar 21 away from the support bar 201 is provided with an engaging device. The first vertical rod 21 can not only support and protect the support rod 201, but also can rotate around the first rotating shaft 20, and after being turned over 180 degrees, it is located on both sides of the standing board 3 and distributed upwards, thereby facilitating the installation of the standing board 3 top. The construction personnel provide temporary support to ensure the safety performance of the construction personnel, and fix the rotated first vertical rod 21 through the engaging device to ensure the stability of the first vertical rod 21 and the stability of the first rotating shaft 20 during the construction process. The outer surface is provided with a full gear 23, and the full gear 23 will rotate with the rotation of the first rotating shaft 20 to ensure its transmission connection. The side of the first vertical bar 21 away from the support part 2 is provided with a buckle 33. The initial state The opening of the lower buckle 33 faces downward, so when the buckle 33 is at the bottom position, it mainly plays the role of clamping and fixing, and when the buckle 33 is turned over 180 degrees, the direction of the buckle 33 is upward and opposite to the side of the standing board 3 , so at this time the buckle 33 will become a hanging buckle, and then temporarily mount the construction equipment of the construction personnel to ensure the safety and comfort of the construction personnel.

One side of the support rod 201 and the second fixed block 26 are arranged at the bottom of the first fixed block 19, and the second rotating shaft 27 is rotatably connected between the adjacent two second fixed blocks 26, and the second rotating shaft 27 can rotate around the second The fixed block 26 rotates, the outer surface of the second rotating shaft 27 is provided with the second vertical rod 28, the outer surface of the second rotating shaft 27 is provided with a half gear 30, half of the outer surface of the half gear 30 has teeth and the other half is a smooth surface, so When the second rotating shaft 27 rotates at a certain angle, when the top of the second vertical rod 28 and the buckle 33 are squeezed each other, the half gear 30 rotates with the second rotating shaft 27, and the teeth on the surface of the half gear 30 rotate from the original outwards to Close to the standing board 3 inwardly, one side of the second vertical bar 28 is provided with a second torsion spring 31, and the other end of the second torsion spring 31 is fixedly connected with a side of the second fixed block 26, by means of the second torsion spring 31 can Realize the rotation of the second rotating shaft 27 in the first stage, and rotate the tooth surface of the second vertical bar 28 and the half gear 30 to a suitable position, and one side of the standing board 3 and the first bottom bar 101 is provided with a fixed ring 32 to fix The inside of the ring 32 is slidingly connected with a Z-shaped tooth plate 24, and the Z-shaped tooth plate 24 meshes with the full gear 23 and the half gear 30 respectively. The fixed ring 32 mainly limits the position of the Z-shaped tooth plate 24, thereby ensuring that the Z-shaped tooth plate The plate 24 can only move in the vertical direction, and when the second rotating shaft 27 rotates at a certain angle, the tooth surface of the half gear 30 and the side of the Z-shaped tooth plate 24 carry out gear meshing, and one side of the Z-shaped tooth plate 24 is in contact with the Z-shaped tooth plate 24. The full gear 23 meshes, and the meshing surfaces of the Z-shaped tooth plate 24 and the half gear 30 and the full gear 23 are different, so when the full gear 23 rotates, the Z-shaped tooth plate 24 moves downward, and the Z-shaped tooth plate 24 moves downward to drive the half The gear 30 rotates, and the rotation of the half gear 30 drives the second vertical bar 28 to continue to drive the second torsion spring 31 to rotate and rotate accordingly.

A plurality of first connecting rods 22 are arranged in a uniform array between the two first vertical rods 21, and a plurality of groups of second connecting rods 29 are arranged in a uniform array between the two second vertical rods 28, and the first connecting rods 22 and the second The connecting rod 29 can not only play the role of supporting, connecting and fixing the first vertical rod 21 and the second vertical rod 28 respectively, but also serves as a temporary step for the feet to facilitate construction workers to reach the top of the standing board 3 during work.

The engaging device comprises a wedge-shaped spring block, the wedge-shaped spring block is fixedly connected to one side of the first vertical bar 21, and one side of the standing board 3 is provided with a wedge-shaped draw-in slot, and the wedge-shaped spring block and the wedge-shaped draw-in slot are engaged with each other. The wedge-shaped spring block in the middle makes the first rotating shaft 20 rotate to drive the first vertical bar 21 to rotate 180 degrees, and the wedge-shaped spring block is clamped and fixed with the wedge-shaped slot, thereby ensuring the stability and fixing performance of the first vertical bar 21. When the first vertical bar 21 needs to be disassembled, it is only necessary to manually press the wedge-shaped spring block to disengage the wedge-shaped spring block from the wedge-shaped slot, and turn the first vertical bar 21 downward.

The second rotating shaft 27 is parallel to the fixed screw rod 11, and the second vertical rod 28 is parallel to the fixed screw rod 11, so when the second vertical rod 28 rotates, the fixed screw rod 11 hinders its rotation.

During use, push the moving wheel 16 to move the scaffold to a suitable position. In the initial state, the first vertical bar 21 is in a vertically downward state in the vertical direction under the elastic force of the first torsion spring 25. Each first connecting bar 22 It is in a relatively stable position, and the end of the second vertical rod 28 away from the second rotating shaft 27 is also in a vertical downward state. One side of the fixed screw rod 11 is clamped, and the second torsion spring 31 is in a twisted state when the second vertical rod 28 is in this position. When the entire scaffold position is relatively inclined, the end of the second vertical rod 28 on one side is Due to its own weight, it will continue to twist the second torsion spring 31 to move away from the end of the support part 2, so the second vertical rod 28 and the fixed screw rod 11 cannot contact each other, and then remind the construction personnel that the level of the ground does not meet the requirements, and it is necessary to further improve the ground. The levelness is adjusted to meet the actual processing needs.

By adjusting the coefficient of elasticity of the second torsion spring 31 and the weight of the second vertical bar 28 away from the end of the second rotating shaft 27, the detection range of the degree of inclination of the scaffold to the ground can be adaptively adjusted. Specifically, when the second torsion spring 31 When the coefficient of elasticity is small, the gravity at the end of the second vertical rod 28 is relatively large, and it can be seen from the figure that since the second rotating shaft 27 is parallel to the fixed screw rod 11, the second vertical rod 28 is parallel to the fixed screw rod 11, so the second vertical rod 28 is parallel to the fixed screw rod 11. The rod 28 is clamped on the side of the fixed screw 11 away from the support part 2 in the initial state, so the second vertical rod 28 is in a non-vertical state, and there is an angle between the fixed screw 11 and the second vertical rod 28. Under the action of the elastic force of the second torsion spring 31, the second vertical bar 28 is pressed into contact with the side of the fixed screw rod 11 away from the support part 2, and when the ground is inclined, the second vertical bar 28 on the side inclined downward will be under the condition of its own weight. It is in a vertical state, so the second vertical rod 28 drives the second rotating shaft 27 to continue to twist the second torsion spring 31 to rotate away from the side of the support part 2, there is a gap between the second vertical rod 28 and the fixed screw rod 11, and the other If the second vertical rod 28 on the side continues to press and contact with the fixed screw rod 11, it means that the ground is tilted, and the levelness of the ground needs to be adjusted again.

When the levelness of the ground meets the requirements and the scaffolding needs to be fixed, by rotating the fixing screw 11, the fixing screw 11 is continuously moved downwards and fixedly plugged to the ground, thereby ensuring that the whole scaffold is in a stable state, and when the fixing screw 11 When 11 moves downwards and connects with the ground, the top of the fixed screw 11 moves down continuously. When it moves down to a certain distance, one side of the fixed screw 11 is separated from the side of the second vertical rod 28, and the fixed screw 11 is connected to the second vertical rod. One side of 28 no longer has the blocking function. At this time, the second vertical bar 28 drives the second rotating shaft 27 to rotate around the second fixed block 26 under the action of the second torsion spring 31. When the rotation angle of the second vertical rod 28 is greater than 180 degrees under the drive of the second torsion spring 31, the end of the second vertical rod 28 is spliced with the end of the first vertical rod 21, and the end of the second vertical rod 28 is upward At the same time, it is clamped with the buckle 33 at the end of the first vertical bar 21. At the same time, the first vertical bar 21 is in a vertical state under the action of the first torsion spring 25, and the second torsion spring 31 is on the second vertical bar 28. The elastic effect of the vertical rod is canceled, so the second vertical rod 28 does not continue to rotate, the second vertical rod 28 and the first vertical rod 21 are connected as a whole, and the first connecting rod 22 and the second connecting rod 29 are parallel to each other at the same time, the construction personnel It is convenient to step on the second connecting rod 29 and the first connecting rod 22 to climb to the top of the standing board 3, thereby facilitating the construction personnel to reach the construction position, improving the operation convenience of the construction personnel, and further ensuring the safety and speed of the construction personnel.

The rotation of the first rotating shaft 20 drives the half gear 30 to rotate, and when the second vertical rod 28 drives the first rotating shaft 20 to rotate to the bottom of the first vertical rod 21, the tooth surface of the half gear 30 meshes with the Z-shaped tooth plate 24, and at the same time After the builders arrive at the top of the standing board 3, in order to ensure the stability of the builders, the first vertical bar 21 can be turned upwards manually, and the first torsion spring 25 will be twisted when the first vertical bar 21 is turned upwards. 21 After turning up 180 degrees and being perpendicular to the standing board 3, the engaging device on the side of the first vertical bar 21 is engaged with the wedge-shaped slot of the standing board 3. At this time, the first vertical bar 21 is in a stable vertical state , and then the first vertical bar 21 is changed from the original role of assisting climbing to the temporary handrail effect of the construction personnel on the top of the standing board 3, and the buckle 33 on the first vertical bar 21 side is no longer on the second vertical bar 28 for displacement clamping, and turn the opening up to become a conventional hanging buckle, which is convenient for construction personnel to directly hang the device and equipment they carry on the buckle 33, further improving the construction safety and convenience of construction personnel, and meeting the actual construction requirements. requirements, while increasing the performance versatility and spatial variability of each component, with strong adaptability and quick operation.

At the same time, when the first vertical bar 21 drives the first rotating shaft 20 to rotate, the full gear 23 on one side of the first rotating shaft 20 rotates thereupon, and the full gear 23 will rotate with the Z-shaped tooth plate 24 when rotating. The tooth plate 24 is located on the side of the full gear 23 close to the support part 2, so when the full gear 23 rotates upward with the first rotating shaft 20, the Z-shaped tooth plate 24 will move downward in the fixed ring 32, and the Z When the tooth plate 24 moves downward, the tooth surface at the bottom of the tooth plate will mesh with the half gear 30 to rotate. It can also be seen from the figure that the Z-shaped tooth plate 24 is located on the side of the half-gear 30 away from the support part 2, so when the Z-shaped tooth plate 24 When moving down, it will drive the half gear 30 to rotate to the bottom, so the second shaft 27 and the second vertical bar 28 on the outer surface will be driven to rotate synchronously when the half gear 30 rotates. The numbers are all the same, so when the first vertical rod 21 drives the full gear 23 to rotate 180 degrees, the half gear 30 will synchronously drive the second vertical rod 28 to rotate 180 degrees downward, and the end of the second vertical rod 28 is at the fixed screw rod 11 and in contact with it, the whole device is in a relatively stable state, so when the fixing screw 11 shakes and loses its fastening effect with the ground, it often occurs that it moves upwards, and when the fixing screw 11 moves upwards When the trend of loosening occurs, the top of the fixing screw 11 is supported and squeezed by the end of the second vertical rod 28, so that it cannot be loosened and pulled out, which further improves the effect of scaffolding and fixing, and avoids loosening during long-term use and causes the top of the standing board 3 The personal safety of the construction personnel, to ensure the stability and reliability of the device.

After the use is completed, only the construction personnel on the top of the standing plate 3 need to manually release the engaging device, mainly to loosen the wedge-shaped spring block, and then the first rotating shaft 20 is driven around the first rotating shaft 20 under the torsion of the first torsion spring 25. When the fixed block 19 rotates, the first rotating shaft 20 drives the first vertical bar 21 to return to its original position. At the same time, when the first rotating shaft 20 rotates, the full gear 23 will preferentially drive the Z-shaped gear plate 24 to move in the reverse direction, and the movement of the Z-shaped gear plate 24 will drive the half gear. The gear 30 rotates in the reverse direction, and when the half gear 30 rotates in the reverse direction, it drives the second rotating shaft 27 to rotate in the opposite direction, and the second rotating shaft 27 drives the second vertical rod 28 to move in reverse and return to the bottom of the first vertical rod 21. At the same time, the second torsion spring Under the action of the torsion force of 31 and the joint action of the Z-shaped tooth plate 24, the second vertical bar 28 will return to its original position prior to the first vertical bar 21, thus effectively preventing the buckle 33 from returning to the second vertical bar 28. Obstacle effect when in situ, then construction workers climb down from the standing board 3 along the first connecting rod 22 and the second connecting rod 29, and then complete the construction. When the scaffolding needs to be removed, first manually rotate the second vertical rod 28 , when the second vertical rod 28 rotates, the second torsion spring 31 will be twisted, and the second vertical rod 28 will be twisted more than 180 degrees, so that the end of the second vertical rod 28 is positioned at the fixed screw rod 11 away from the support portion while facing 2 side, pull up the fixed screw 11 at the same time, so that the side of the fixed screw 11 will limit and fix the end of the second vertical bar 28, and then can completely return to the original position, and then only need to use the moving wheel 16 Just push the device away from the construction site.

This device not only satisfies the problems of climbing and handrails during the use of scaffolding, improves the adaptability and convenience of operation of scaffolding, improves its safety performance, but also can detect the levelness of the construction ground, thereby improving its construction accuracy and improving The stability of the scaffold, and the cooperation between the various components, the mutual support in function, the structure has different functions and effects at different stages, the versatility is strong, and the structure is stable.
