Description

Technical Field

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

[0002] Construction refers to the production activities during the implementation phase of engineering construction, and is the construction process of various types of buildings. In order to ensure the smooth progress of each construction process, a work platform, namely scaffolding, will be set up. Scaffolding is a facility commonly used at construction sites. The most commonly used scaffolding at present is the coupler-type steel pipe scaffolding, which uses couplers to cross-fix the horizontal and vertical pipes together.

[0003] The vertical poles and horizontal poles of the coupler-type steel pipe scaffolding are generally fastened together by fasteners similar to clamps, and then fixed by bolts to achieve the connection and fixation of the horizontal poles and vertical poles. However, the long-term transportation of materials and the movement of workers on the scaffolding will produce large vibrations. Although the structure of this method is simple, it will become unstable due to long-term vibrations, and long-term vibrations will make the components easy to fall off, posing a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the background technology and to propose a safety scaffold for construction.

[0005] The cam is connected to the second rod by a plurality of connecting rods, and the connecting rods are connected to the cam by a plurality of connecting rods.

[0006] Preferably, the bottom of the No. 1 rod is connected to a support assembly, and the support assembly includes a base, and the outer surface of the base is provided with bolts fixed to the ground.

[0007] Preferably, a sleeve frame is provided on the bottom surface of the base, an extension plate is slidably connected to the inner wall of the sleeve frame, holes for bolts to pass through are provided inside the extension plate, and the number of the extension plates is several.

[0008] Preferably, the top of the extension plate is hinged with a hinged rod, the outer surface of the No. 1 rod is provided with a No. 1 thread, the No. 1 thread of the No. 1 rod is threadedly connected to a gear ring, the bottom of the gear ring is rotatably connected to a circular ring, and the end of the hinged rod away from the extension plate is hinged to the outer surface of the circular ring.

[0010] Preferably, the grab hook is engaged with the first tooth plate and the second tooth plate respectively through teeth, and the grab hook is engaged with the through hole inside the hollow ring body when it is engaged with the second tooth plate and rotates.

[0011] In summary:

[0012] When the second threaded ring is moved, the sliding rod is pulled, and the sliding rod pulls the connecting ring. At this time, when the connecting ring drives the grab hook to move to the second tooth plate, the teeth on the grab hook are engaged with the second tooth plate and rotated with the help of the rotating shaft, so that the grab hook is rotated to the front of the through hole of the hollow ring body and continues to move. At this time, the teeth at the grab hook are disengaged from the engagement with the second tooth plate. At this time, the grab hook is extended into the through hole of the hollow ring body and clamped, abandoning the traditional connection in the form of a clamp. The new connection method is used to achieve the quick installation and connection of the first rod and the second rod, and the connection between the grab hook and the hollow ring body can also be stabilized for a second time, thereby improving the stability of the scaffold connection.

[0019] Reference Figure 3 and Figure 4 The bottom of the base 21 is provided with a sleeve 22, and the inner wall of the sleeve 22 is slidably connected to an extension plate 23. The interior of the extension plate 23 is provided with holes for the bolts 211 to pass through. The number of extension plates 23 is several. The gear ring 25 is rotated, and the gear ring 25 rotates along the No. 1 thread 11 and squeezes the ring to move. The ring moves and drives the hinged rod 24 to pull the extension plate 23 out of the interior of the sleeve 22. At this time, the extension plate 23 can extend a plurality of holes for the bolts 211 to pass through. The top of the extension plate 23 is hinged with a hinged rod 24, and the outer surface of the No. 1 rod 1 is provided with a No. 1 thread 11. The No. 1 thread 11 of the No. 1 rod 1 is threadedly connected with a gear ring 25. The bottom of the gear ring 25 is rotatably connected with a ring, and the end of the hinged rod 24 away from the extension plate 23 is hinged to the outer surface of the ring.

[0020] Reference Figure 1 and Figure 2As shown, in this embodiment: the rod connecting assembly 4 includes a No. 2 thread 42, a No. 1 tooth plate 47 and a No. 2 tooth plate 48 provided on the outer surfaces of the No. 1 rod 1 and the No. 2 rod 41, and a No. 2 thread ring 43 is threadedly connected at the No. 2 thread 42. A limiting ring groove is provided on one side of the No. 2 thread ring 43. The inner wall of the limiting ring groove is slidably and non-detachably connected to a sliding rod 44. The end of the sliding rod 44 away from the No. 2 thread ring 43 is fixedly connected to a connecting ring 45 sleeved on the outer surface of the No. 2 rod 41, and the interior of the connecting ring 45 is rotatably connected to a plurality of grab hooks 46 through a rotating shaft. One end of the outer surface of the grab hook 46 is provided with a tooth 461, and the outer surface of the No. 2 rod 41 is provided with a No. 1 tooth plate 47 and a No. 2 tooth plate 48. The grab hook 46 is respectively connected to the No. 1 tooth plate 47 and the No. 2 tooth plate through the tooth 461. The plates 48 engage with each other and rotate the No. 2 threaded ring 43, causing the No. 2 threaded ring 43 to rotate and move along the No. 2 thread 42. When the No. 2 threaded ring 43 moves, it pulls the slide bar 44, causing the slide bar 44 to pull the connecting ring 45. At this time, when the connecting ring 45 drives the hook 46 to move to the No. 2 tooth plate 48, the hook 46 engages with the No. 2 tooth plate 48 and rotates to engage with the through hole inside the hollow ring body 32. The teeth 461 on the hook 46 engage with the No. 2 tooth plate 48 and rotate with the help of the rotating shaft, causing the hook 46 to rotate to the front of the through hole of the hollow ring body 32. At this time, it continues to move, and the teeth 461 at the hook 46 disengage from the No. 2 tooth plate 48. At this time, the hook 46 extends into the through hole of the hollow ring body 32 and engages, so that the No. 1 rod 1 and the No. 2 rod 41 can be quickly connected.

[0021] Working principle: When assembly is required, first prepare the connecting sleeve 3, and then thread the No. 1 rod 1 or the No. 2 rod 41 in the upper, lower, left and right front of the connecting sleeve 3. When the insertion is completed, the No. 2 threaded ring 43 is rotated to make the No. 2 threaded ring 43 rotate and move along the No. 2 thread 42, and the No. 2 threaded ring 43 pulls the slide bar 44 when it moves, so that the slide bar 44 pulls the connecting ring 45. At this time, the connecting ring 45 drives the grab hook 46 to move to the No. 2 tooth plate 48, and the meshing teeth 461 on the grab hook 46 engage with the No. 2 tooth plate 48, and rotate with the help of the rotating shaft, so that the grab hook 46 rotates to the front of the through hole of the hollow ring body 32, and then continues to move, and the meshing teeth 461 at the grab hook 46 disengage from the No. 2 tooth plate 48 At this time, the grab hook 46 extends into the through hole of the hollow ring body 32 and is clamped, so that the No. 1 rod 1 and the No. 2 rod 41 can be quickly connected, and it can also have a secondary stabilization effect. When the number of connections of the No. 2 rod 41 increases, it is necessary to increase the support between the base 21 and the ground. At this time, the gear ring 25 is rotated, and the gear ring 25 rotates along the No. 1 thread 11 and squeezes the ring to move. The ring moves and drives the hinged rod 24 to pull the extension plate 23 out of the interior of the sleeve frame 22. At this time, the extension plate 23 can extend a plurality of holes for the bolts 211 to pass through. At this time, multiple bolts 211 are sequentially passed through several holes to connect to the ground, which increases the support and stability performance of the base 21 and improves the connection stability of the scaffold.
