[0049] The existing scaffolding construction method proposed above is usually to set a base at the bottom of the elevator shaft, and then build it up layer by layer. Due to the small internal space of the elevator shaft, the construction process is inconvenient to operate, and the installation is time-consuming and labor-intensive. After the subsequent completion, it needs to be disassembled, and the disassembly process is also time-consuming and labor-intensive, which brings inconvenience to the construction process. Moreover, the scaffolding built layer by layer will reduce its strength as the building height increases. The more layers are built, the greater the force on the bottom scaffolding, and the lower the stability, which cannot meet the needs of fast construction and safe construction. The present invention provides a detachable steel structure scaffolding for an elevator shaft.

[0050] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0051] In order to illustrate the structure of the detachable scaffolding for the elevator shaft provided by the present invention, Figures 1 to 7 The structure of the detachable scaffolding used in the elevator shaft is exemplarily indicated from different angles.

When fixing the bearing frame 1 and the vertical limiting frame 2, multiple sets of bolts are respectively passed through the first fixing hole 11 and the second fixing hole 21 and plugged into the ground and the wall.

[0055] In the embodiment of the present invention, a fitting block 32 is provided at the bottom of the operating platform 3, and the operating platform 3 is engaged with the carrier frame 1 through the fitting block 32. The fitting block 32 and the carrier frame 1 are engaged, so that the operating platform 3 forms a preliminary limit when engaged with the carrier frame 1, thereby making the operating platform 3 stably engaged with the carrier frame 1.

[0056] Wherein, a first clamping column 31 is arranged on the operating platform 3, and the operating platform 3 is movably clamped with the bottom of the secondary platform pillar 4 through the first clamping column 31; a second clamping column 51 is arranged on the secondary platform body 5, and the secondary platform body 5 is movably clamped with the top of the secondary platform pillar 4 through the second clamping column 51.

[0058] In the embodiment of the present invention, the operating platform 3 and the secondary platform body 5 facilitate the workers to quickly carry out construction in the elevator shaft. This scaffold is easy to install and has good stability, meeting the use requirements; when assembling, first transport the bearing frame 1 and the limit frame 2 to the elevator shaft opening on each floor, and then push part of the bearing frame 1 into the elevator shaft opening. At the same time, make the limit frame 2 fit the wall, and use bolts to fix the bearing frame 1 and the vertical limit frame 2 to the ground and the wall respectively.

[0059] Then, the operating platform 3 is snapped onto the supporting frame 1, so that construction personnel can enter the elevator shaft to carry out construction work. When the working height needs to be increased, the secondary platform pillar 4 and the operating platform 3 are snapped and locked, and the secondary platform body 5 and the secondary platform pillar 4 are also snapped and locked, so as to facilitate rapid construction at high places of the elevator shaft.

[0060] When the secondary platform pillar 4 and the secondary platform body 5 need to be installed, the first clamping column 31 is connected to the secondary platform pillar 4, so that the secondary platform pillar 4 is clamped and positioned on the operating platform 3, and then the second clamping column 51 is connected to the secondary platform pillar 4, so that the secondary platform body 5 is clamped and positioned on the secondary platform pillar 4;

[0061] Among them, the first locking hole 311 and the second locking hole 52 are respectively opened on the first clamping column 31 and the second clamping column 51. Through the locking mechanism 7, the operating platform 3, the secondary platform pillar 4 and the secondary platform body 5 can ensure convenient docking and stable connection when docking. The secondary platform pillar 4 and the first clamping column 31 are plugged and locked by the locking rod 73, and the secondary platform pillar 4 and the second clamping column 51 are also plugged and locked by the locking rod 73.

[0062] Among them, when the operating platform 3, the secondary platform pillar 4 and the secondary platform body 5 are connected as a whole, the double-threaded screw 74 is rotated to make the double-threaded screw 74 rotate and drive the adjustment block 72 to move, and the adjustment block 72 drives the locking rod 73 to move, and finally multiple groups of locking rods 73 are respectively inserted into the first locking hole 311 and the second locking hole 52, so that the operating platform 3, the secondary platform pillar 4 and the secondary platform body 5 are quickly connected and the position of the connection is locked.

[0063] In the embodiment of the present invention, the limiting mechanism 8 includes two groups of vertical plates 81 fixedly connected to the bottom of the operating platform 3, two groups of guide rails 82 arranged between the two groups of vertical plates 81, two groups of clamping platforms 83 sleeved on the two groups of guide rails 82, and two groups of springs 85, wherein the two groups of clamping platforms 83 are sleeved on both ends of the two groups of guide rails 82 and connected to the two groups of vertical plates 81, and the two groups of springs 85 are arranged between the two groups of clamping platforms 83. A limiting plug rod 84 is arranged on the side of each clamping platform 83, a through hole corresponding to the limiting plug rod 84 is arranged on each vertical plate 81, and a limiting hole 12 is arranged on the support frame, wherein the limiting plug rod 84 passes through the through hole and is movably inserted into the limiting hole 12.

[0064] Among them, through the limiting mechanism 8, when the operating platform 3 and the supporting frame 1 are clamped, it is convenient to quickly clamp and limit, so that the overall construction of the scaffolding is convenient and stable; in the process of clamping the operating platform 3 and the supporting frame 1, first pull the clamping table 83, so that the clamping table 83 drives the limiting plug rod 84 to move horizontally, and then the operating platform 3 and the supporting frame 1 are clamped. After they are fully clamped, push the clamping table 83 and the limiting plug rod 84 to move, so that the limiting plug rod 84 passes through the vertical plate 81 and is inserted into the inside of the limiting hole 12, thereby realizing the rapid clamping and limiting of the operating platform 3 and the supporting frame 1.

[0065] Among them, a spring 85 is fixedly connected between the two groups of clamping platforms 83, and a push handle 831 is fixedly connected to the clamping platform 83. Through the setting of the spring 85, when the limiting rod 84 passes through the vertical plate 81 and is inserted into the inside of the limiting hole 12, the spring 85 applies a thrust to the clamping platform 83 and the limiting rod 84. Under the action of the spring 85, the limiting rod 84 is stable when inserted into the inside of the limiting hole 12, thereby ensuring good stability between the operating platform 3 and the supporting frame 1.
