技术领域Technical Field
本发明属于爬架提升系统的技术领域，具体涉及一种用于爬架提升的滑轮式正挂葫芦安装结构。The invention belongs to the technical field of climbing frame lifting systems, and in particular relates to a pulley-type upright hoist installation structure used for climbing frame lifting.
背景技术Background Art
爬架又叫提升架，是近年来开发的新型脚手架体系，主要应用于高层剪力墙式楼盘。它能沿着建筑物往上攀升或下降。这种体系使脚手架技术完全改观：一是不必翻架子；二是免除了脚手架的拆装工序(一次组装后一直用到施工完毕)，且不受建筑物高度的限制，极大的节省了人力和材料。并且在安全角度也对于传统的脚手架有较大的改观。在高层建筑中极具发展优势。The climbing frame, also known as the lifting frame, is a new type of scaffolding system developed in recent years, mainly used in high-rise shear wall buildings. It can climb up or down along the building. This system has completely changed the scaffolding technology: first, there is no need to turn over the frame; second, the scaffolding disassembly and assembly process is eliminated (once assembled, it is used until the construction is completed), and it is not limited by the height of the building, which greatly saves manpower and materials. And from the perspective of safety, it is also a big improvement on the traditional scaffolding. It has great development advantages in high-rise buildings.
爬架葫芦是一种轻小起重机械，适用于爬架的提升系统，具有结构紧凑、体积小、重量轻、效率高、制动可靠、使用方便、起吊速度慢、机体质量轻、机件硬度高、磨损小的特点。在空间较小的工作场所使用更是灵活迅捷，安全方便。Climbing hoist is a light and small lifting machinery, suitable for the lifting system of climbing frame, with compact structure, small size, light weight, high efficiency, reliable braking, easy to use, slow lifting speed, light body mass, high hardness of parts, and small wear. It is more flexible, fast, safe and convenient to use in a small workplace.
现有技术中，用于爬架提升的葫芦一般采用倒挂方式安装，安装在施工现场，工地上水泥、砂浆、尘土飞扬，倒挂葫芦的底部开口向上，极容易进入杂质，为了保证爬架的正常运行，使用过程中必须要有专人负责不定期清洁、保养，但是，即便如此，倒挂葫芦仍然存在过早损坏的情形，系统性能可靠性差，影响施工作业。In the prior art, the hoist used for climbing frame lifting is generally installed in an upside-down manner at the construction site. Cement, mortar and dust are flying on the construction site. The bottom opening of the inverted hoist faces upward, and impurities are easily introduced. In order to ensure the normal operation of the climbing frame, a dedicated person must be responsible for irregular cleaning and maintenance during use. However, even so, the inverted hoist is still prone to premature damage, and the system performance reliability is poor, which affects construction operations.
后有业者研发了正挂葫芦的安装方式，但是，都是采用链条，与链条配合的导轮都是链轮，不仅安装成本高，而且，工地上水泥、砂浆、尘土飞扬，链条和链轮容易积尘，特别是下吊点的链条和链轮之间如果积尘太多，摩擦力增大，能耗增大，运行不顺畅，可靠性降低，存在安全隐患。Later, some industry insiders developed the installation method of hanging hoist, but they all adopted chains, and the guide wheels matched with the chains were sprockets. Not only was the installation cost high, but also, cement, mortar, and dust were flying around on the construction site, and the chains and sprockets were prone to dust accumulation. Especially if there was too much dust between the chain and sprocket at the lower hanging point, the friction would increase, the energy consumption would increase, the operation would not be smooth, the reliability would be reduced, and there would be safety hazards.
有鉴于此，本发明人秉持多年该相关行业之丰富设计开发及实际制作经验，针对现有之缺失，予以研究改良，提供一种用于爬架提升的滑轮式正挂葫芦安装结构，本案由此产生。In view of this, the inventor, based on his rich experience in design, development and actual production in the relevant industry for many years, has conducted research and improvements on the existing deficiencies and provided a pulley-type hanging hoist installation structure for climbing frame lifting, which resulted in the present case.

如图1至图6所示，本发明揭示了一种用于爬架提升的滑轮式正挂葫芦安装结构，在爬架4的高位安装上吊点1，上吊点1上安装一个正挂葫芦6和一个上链轮11；在爬架4的中位安装中吊点2，中吊点2固定在建筑墙体(图中未示出)上；在爬架4的中位还悬空设有吊轮7，吊轮7的上方具有上支点71，吊轮7的下方具有下支点72；在爬架4的低位安装下吊点3，下吊点3上枢接安装滑轮31；链条5的一端固定在吊轮7的上支点71上，先向上绕过上链轮11后，再向下绕过吊轮7，最后链条5的另一端绕过正挂葫芦6；钢丝绳8的一端固定在吊轮7的下支点72上，钢丝绳8绕过滑轮31，另一端固定在中吊点2上。As shown in Figures 1 to 6, the present invention discloses a pulley-type hanging hoist installation structure for climbing frame lifting, wherein an upper hanging point 1 is installed at a high position of a climbing frame 4, and a hanging hoist 6 and an upper sprocket wheel 11 are installed on the upper hanging point 1; a middle hanging point 2 is installed at a middle position of the climbing frame 4, and the middle hanging point 2 is fixed on a building wall (not shown in the figure); a hanging wheel 7 is also suspended at the middle position of the climbing frame 4, an upper fulcrum 71 is provided above the hanging wheel 7, and a lower fulcrum 72 is provided below the hanging wheel 7; a lower hanging point 3 is installed at a low position of the climbing frame 4, and a pulley 31 is pivotally installed on the lower hanging point 3; one end of a chain 5 is fixed on the upper fulcrum 71 of the hanging wheel 7, first passes around the upper sprocket wheel 11 upwards, then passes around the hanging wheel 7 downwards, and finally the other end of the chain 5 passes around the hanging hoist 6; one end of a steel wire rope 8 is fixed on the lower fulcrum 72 of the hanging wheel 7, the steel wire rope 8 passes around the pulley 31, and the other end is fixed on the middle hanging point 2.
本发明工作时，当正挂葫芦6向上拉链条5，链条5带动吊轮7向上行，吊轮7随机将钢丝绳8向上拉，带动下吊点3上升，由此实现爬架4的提升；当正挂葫芦6向下放链条5，链条5带动吊轮7向下行，吊轮7随机将钢丝绳8向下放，带动下吊点3下降，由此实现爬架4的降落。When the present invention is working, when the hanging hoist 6 pulls the chain 5 upwards, the chain 5 drives the hanging wheel 7 upwards, and the hanging wheel 7 randomly pulls the wire rope 8 upwards, driving the lower hanging point 3 to rise, thereby realizing the lifting of the climbing frame 4; when the hanging hoist 6 puts the chain 5 downwards, the chain 5 drives the hanging wheel 7 downwards, and the hanging wheel 7 randomly puts the wire rope 8 downwards, driving the lower hanging point 3 to descend, thereby realizing the descent of the climbing frame 4.
本发明因为在下吊点3采用钢丝绳8与滑轮31配合代替传统的链条与链轮(对应的导轮)配合，结构更简单，安装成本大大降低。钢丝绳8与滑轮31接触面光滑，不像链条和链轮具有齿槽，钢丝绳8与滑轮31之间不积尘，不增加摩擦力，也不增加能耗，运行更加顺畅，可靠性大大提高，消除安全隐患。The present invention uses a steel wire rope 8 and a pulley 31 to replace the traditional chain and sprocket (corresponding guide wheel) at the lower suspension point 3, so the structure is simpler and the installation cost is greatly reduced. The contact surface between the steel wire rope 8 and the pulley 31 is smooth, unlike the tooth grooves of the chain and the sprocket, and there is no dust accumulation between the steel wire rope 8 and the pulley 31, which does not increase the friction force and energy consumption, and the operation is smoother, the reliability is greatly improved, and the safety hazard is eliminated.
本发明进一步将所述上吊点1固定在爬架4龙门架41的两个立杆上。这样，本发明将正挂葫芦6通过上吊点1固定安装在爬架4的龙门架41中，整个安装结构受力更加均匀，正挂葫芦6的上吊点1不会变形，爬架4升降运行更加稳定、可靠、安全。具体地，所述上吊点1为倒置的日字型架体，两端锁固在龙门架41的立杆上，使结构更牢固、稳定。The present invention further fixes the hanging point 1 on two vertical poles of the gantry 41 of the climbing frame 4. In this way, the present invention fixes the upright hoist 6 in the gantry 41 of the climbing frame 4 through the hanging point 1, the whole installation structure is more evenly stressed, the hanging point 1 of the upright hoist 6 will not be deformed, and the lifting operation of the climbing frame 4 is more stable, reliable and safe. Specifically, the hanging point 1 is an inverted Japanese-shaped frame, and both ends are locked on the vertical poles of the gantry 41, making the structure more solid and stable.
为了方便安装，本发明所述吊轮7的下支点72为挂钩，钢丝绳8的一端具有挂环81，借助挂环81挂在挂钩上，使钢丝绳8的一端固定在吊轮7的下支点72上。所述中吊点2上形成卡槽21，卡槽21中固定设置卡柱22，钢丝绳8的另一端固定在卡柱22上。In order to facilitate installation, the lower fulcrum 72 of the hanging wheel 7 of the present invention is a hook, and one end of the wire rope 8 has a hanging ring 81, which is hung on the hook by the hanging ring 81, so that one end of the wire rope 8 is fixed on the lower fulcrum 72 of the hanging wheel 7. A clamping groove 21 is formed on the middle hanging point 2, and a clamping column 22 is fixedly arranged in the clamping groove 21, and the other end of the wire rope 8 is fixed on the clamping column 22.
为了使钢丝绳8运行更顺畅、不扭转、不打结，本发明所述爬架4在滑轮31的上方安装导杆42，导杆42的两端对应滑轮31的两侧形成导环43，绕过滑轮31的钢丝绳8两端分别穿过导环42后再固定在下支点72和中吊点2上。In order to make the wire rope 8 run more smoothly without twisting or knotting, the climbing frame 4 described in the present invention installs a guide rod 42 above the pulley 31, and the two ends of the guide rod 42 correspond to the two sides of the pulley 31 to form a guide ring 43. The two ends of the wire rope 8 that pass around the pulley 31 pass through the guide ring 42 respectively and then are fixed on the lower support point 72 and the middle hanging point 2.
