Description

附着升降脚手架升降装置Attached Lifting Scaffold Lifting Device

【技术领域】【Technical field】

本发明涉及建筑施工吊装设备,特别涉及一种附着升降脚手架升降装置。The invention relates to building construction hoisting equipment, in particular to an attached lifting scaffold lifting device.

【背景技术】【Background technique】

目前,高层和超高层建筑施工时多使用附着升降脚手架(俗称爬架)。附着升降脚手架,是指采用各种形式的架体结构及附着支承结构,依靠设置于架体上或工程结构上的专门升降设备实现升降的施工脚手架。附着升降脚手架采用的升降设备,通常是慢升环链葫芦,其原理如图5所示:环链葫芦的链条22与一附墙固定件70、张紧装置40形成滑轮结构,工作时,该附墙固定件70与建筑结构进行附墙固定,当环链葫芦工作时,链条22传动而带动脚手架升降,而脚手架升降的同时,环链葫芦也同步升降。当升降一层后,进行下一次升降时,便需将该附墙固定件70从当前位置取下,然后将其固定在更高一层的位置处。在重新固定该附墙固定件70时,不仅需要人工拆装该附墙固定件70,而且需要进行倒链,将环链葫芦倒回至合适的距离,才能进行下一次的提升。实际应用时,其费时费力,不利于提高效率。此外,在进行倒链过程中,无法进行准确的控制,而环链葫芦重量较重,若操作不当,环链葫芦则可能会撞损脚手架,从而造成安全事故或造成安全隐患。At present, attached lifting scaffolds (commonly known as climbing frames) are often used in the construction of high-rise and super high-rise buildings. Attached lifting scaffold refers to the construction scaffold that adopts various forms of frame structure and attached support structure, and relies on special lifting equipment installed on the frame or engineering structure to realize lifting. The lifting equipment attached to the lifting scaffold is usually a slow-rising chain hoist. Its principle is shown in Figure 5: the chain 22 of the chain hoist forms a pulley structure with a wall fixing 70 and a tensioning device 40. When working, the The wall-attached fixture 70 is attached to the wall and fixed to the building structure. When the chain hoist is working, the chain 22 drives the scaffold to go up and down, and when the scaffold goes up and down, the chain hoist also goes up and down synchronously. After lifting one level, when lifting next time, just need to take off this wall-attached fixing part 70 from current position, then it is fixed on the position of higher level. When re-fixing the wall-attached fixture 70, not only need to manually disassemble the wall-attached fixture 70, but also need to reverse the chain, and the chain hoist will be returned to a suitable distance before it can be promoted next time. In actual application, it is time-consuming and laborious, which is not conducive to improving efficiency. In addition, accurate control cannot be performed during the chain-rewinding process, and the chain hoist is heavy. If it is not operated properly, the chain hoist may damage the scaffolding, thereby causing safety accidents or potential safety hazards.

The first fixed pulley 41 , the second fixed pulley 42 and the third fixed pulley 43 are used to tension the transmission rope 60 to form a pulley structure for transmission. The first fixed pulley 41 , the second fixed pulley 42 and the third fixed pulley 43 are arranged at intervals, wherein the second fixed pulley 42 is arranged between the first fixed pulley 41 and the third fixed pulley 43 .

所述链条22和所述传动绳60用于传动,其设置方式如下:Described chain 22 and described transmission rope 60 are used for transmission, and its setting mode is as follows:

如图1~图4所示,所述链条22的中部套设于所述主链轮23上,该链条22的一端依次绕过所述第一传动轮311、第一从链轮24而与传动绳60的一端连接;该链条22的另一端依次绕过第四传动轮512、第二从链轮25而与传动绳60的另一端连接。所述传动绳60的一端与链条22连接时,其另一端依次绕过第一定滑轮41、第二传动轮312、第二定滑轮42、第四传动轮512、第三定滑轮43而与链条22的另一端连接,从而使得张紧装置40、链条22、传动绳60、第一固定件30、第二固定件50、升降装置20之间形成封闭链式的滑轮结构,可用于传动。As shown in Figures 1 to 4, the middle part of the chain 22 is sheathed on the main sprocket 23, and one end of the chain 22 goes around the first transmission wheel 311 and the first slave sprocket 24 in sequence to connect with One end of the transmission rope 60 is connected; the other end of the chain 22 goes around the fourth transmission wheel 512 and the second slave sprocket 25 in turn to connect with the other end of the transmission rope 60 . When one end of the transmission rope 60 was connected with the chain 22, its other end walked around the first fixed pulley 41, the second transmission pulley 312, the second fixed pulley 42, the fourth transmission pulley 512, and the third fixed pulley 43 successively. The other end of the chain 22 is connected so that a closed chain pulley structure is formed between the tensioning device 40, the chain 22, the transmission rope 60, the first fixing member 30, the second fixing member 50 and the lifting device 20, which can be used for transmission.

工作时,将固定件中的其中一个固定件,如第一固定件30与建筑结构进行附墙固定,然后启动所述升降装置20,在所述驱动电机21的作用下,所述链条22、传动绳60进行传动,而使得除第一固定件30以外的整体装置进行升降,同时,固定件中的另一个固定件,如第二固定件50也同步升降。当整体装置升降至所需高度时,将原来的固定件——第一固定件30与建筑结构分离,然后将另一个固定件——第二固定件50与建筑结构进行附墙固定,然后启动升降装置20,便可实现逐层升降。During work, one of the fixing parts in the fixing parts, such as the first fixing part 30, is fixed to the wall with the building structure, and then the lifting device 20 is started, and under the action of the driving motor 21, the chain 22, The driving rope 60 is driven to make the whole device except the first fixing part 30 go up and down, and at the same time, another fixing part in the fixing parts, such as the second fixing part 50 is also lifted up and down synchronously. When the overall device is lifted to the required height, separate the original fixing part - the first fixing part 30 from the building structure, and then attach the other fixing part - the second fixing part 50 to the building structure, and then start Lifting device 20 just can realize layer by layer lifting.

为更详细的描述其工作原理,本实施例以提升为例进行说明:In order to describe its working principle in more detail, this embodiment uses promotion as an example to illustrate:

如图2所示,当前整个装置处于较低楼层,如最低处位于1F位置。此时,将第一固定件30与建筑结构进行附墙固定,将第一固定件30固定在较高处位置,如图2所示的3F位置;此时,启动所述驱动电机21,驱动电机21正转,如图2所示的顺时针方向,链条22、传动绳60沿图2所示的方式进行传动,从而带动升降装置20、第二固定件50、脚手架主体10、张紧装置40向上提升。As shown in Figure 2, the entire device is currently on a lower floor, for example, the lowest place is located at 1F. At this point, the first fixture 30 is attached to the building structure and fixed to the wall, and the first fixture 30 is fixed at a higher position, such as the 3F position shown in Figure 2; at this time, start the drive motor 21 to drive Motor 21 forward rotation, clockwise direction as shown in Figure 2, chain 22, transmission rope 60 carry out transmission along the mode shown in Figure 2, thereby drive lifting device 20, second fixing part 50, scaffold main body 10, tensioning device 40 uplift.

当升降装置20、第二固定件50、脚手架主体10、张紧装置40被提升一个楼层时,其整体状态如图3所示:其整个装置的最低处位于2F位置,第二固定件50位于4F位置;此时,将第一固定件30与建筑结构分离,然后将第二固定件50固定在4F位置的建筑结构上,然后驱动电机21按如图3所示的逆时针方向进行反转,使得链条22、传动绳60沿图3所示的方向进行传动,带动升降装置20、第一固定件30、脚手架主体10、张紧装置40向上提升。When the lifting device 20, the second fixing member 50, the scaffold body 10, and the tensioning device 40 are lifted to one floor, their overall state is as shown in Figure 3: the lowest point of the whole device is at the 2F position, and the second fixing member 50 is at the 4F position; at this time, separate the first fixing part 30 from the building structure, then fix the second fixing part 50 on the building structure at the 4F position, and then drive the motor 21 to reverse in the counterclockwise direction as shown in Figure 3 , so that the chain 22 and the transmission rope 60 are driven in the direction shown in FIG. 3 , driving the lifting device 20 , the first fixing member 30 , the scaffold main body 10 , and the tensioning device 40 to lift upward.

当升降装置20、第一固定件30、脚手架主体10、张紧装置40被提升一个楼层时,其整体状态如图4所示:其整个装置的最低处位于3F位置,第一固定件30位于5F位置,此时,将第二固定件50与建筑结构分离,然后将第一固定件30固定在5F位置,然后顺序重复上述步骤,便可进行逐层提升。该过程中,其基本思路是,轮番固定第一固定件30和第二固定件50,然后通过控制驱动电机21的正转反转,轮番的提升未被固定的另一个固定件和脚手架主体10,从而实现逐层提升的目的。When the lifting device 20, the first fixing member 30, the scaffold body 10, and the tensioning device 40 are lifted to one floor, their overall state is shown in Figure 4: the lowest point of the whole device is at the 3F position, and the first fixing member 30 is at the 5F position, at this time, the second fixing part 50 is separated from the building structure, and then the first fixing part 30 is fixed at the 5F position, and then the above steps are repeated sequentially to carry out layer-by-layer lifting. In this process, the basic idea is to fix the first fixing part 30 and the second fixing part 50 in turn, and then by controlling the forward rotation and reverse rotation of the driving motor 21, the other fixing part and the scaffold main body 10 which are not fixed are lifted in turn. , so as to achieve the purpose of layer-by-layer improvement.

当需要进行下降操作时,其基本原理同上,下降时只需控制驱动电机21的转动方向与提升时的转动反向相反即可。When it is necessary to perform a descending operation, its basic principle is the same as above, and only need to control the direction of rotation of the drive motor 21 when descending is opposite to the direction of rotation during lifting.

尽管通过以上实施例对本发明进行了揭示,但是本发明的范围并不局限于此,在不偏离本发明构思的条件下,以上各构件可用所属技术领域人员了解的相似或等同元件来替换。Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements understood by those skilled in the art.
