Description
技术领域 technical field
本发明属于电力系统安装维修设备技术领域，特别是一种变电站用轻便起吊装置。 The invention belongs to the technical field of power system installation and maintenance equipment, in particular to a portable lifting device for a substation.
背景技术 Background technique
在电站扩建或改造工程中，起吊设备通常使用大型吊车。由于吊车体积庞大，在带电设备区使用，其起重臂的摆动和抬升受现场空间位置和周围带电设备的限制，作业很不方便，并严重存在事故隐患，有时不得不扩大停电区域范围以满足使用条件。例如更换110kV室外电流互感器时，一般电流互感器位于开关的后面，吊车站在路上，起重臂要经过开关才能起吊互感器，起重臂抬起高度又受上方过线的影响，摆动角度受开关的限制；再如更换110kV母线PT时，其安装位置或者吊车够不着，或者起吊高度受上方带电母线的影响；又如，更换或安装室外110kV甲（旁）刀闸、35kV室外开关、110kV线路PT等作业中，都存在起重设备受现场条件限制而扩大停电范围，甚至不能使用起重设备等情况。若使用叉车，又存在抬升高度不够、自重较大、运输不方便等问题。这类作业在变电检修或安装扩建工程中非常常见，因而极大地影响着工程施工周期长，且往往造成停电范围大、时间长，降低输变电效率，以及作业安全系数低等情况，截至目前，这一问题一直未能得到较为理想的解决。 In the expansion or renovation project of the power station, the lifting equipment usually uses a large crane. Due to the large size of the crane, it is used in the live equipment area. The swing and lifting of the boom are limited by the site space and the surrounding live equipment. The operation is very inconvenient and there are serious accident hazards. Sometimes the power outage area has to be expanded to meet the Conditions of Use. For example, when replacing a 110kV outdoor current transformer, the current transformer is generally located behind the switch, and the crane is on the road. The lifting arm must pass the switch to lift the transformer. Restricted by the switch; for another example, when replacing the 110kV bus PT, its installation position or the crane cannot reach it, or the lifting height is affected by the live bus above; another example is to replace or install the outdoor 110kV A (side) switch, 35kV outdoor switch, In 110kV line PT and other operations, there are cases where lifting equipment is limited by site conditions and the scope of power outages is expanded, or even lifting equipment cannot be used. If a forklift is used, there are problems such as insufficient lifting height, large dead weight, and inconvenient transportation. This type of operation is very common in power substation maintenance or installation and expansion projects, which greatly affects the long construction period of the project, and often results in large-scale and long-term power outages, reduced power transmission and transformation efficiency, and low operating safety factors. At present, this problem has not been satisfactorily resolved.

具体实施方式 detailed description
本发明的变电站用轻便起吊装置，具有一个底座2，底座2上安装有升降吊杆1，用于电气设备的起升。在升降吊杆1的顶端通过旋转构件连接有悬臂吊架7，悬臂吊架7上设有悬绳挂接件5，用于悬挂电气设备6。在底座2的一侧铰接有用于移运起吊装置的移动小车3，该移动小车3上连接有与所述升降吊杆1连接的吊杆立放液缸4，用于升降吊杆1的立起和放倒。所述升降吊杆1根据变电站使用的需要采用一级或多级升降液缸，起吊更加方便。所述升降液缸和吊杆立放液缸4配套连接有油泵及控制箱。所述升降吊杆1上设有1～3个用于连接电气设备6安装基础柱9的定位抱箍8，能将升降吊杆1和安装电气设备6的安装基础柱9固定在一起，可以升降吊杆1吊装作业的稳定性。 The portable lifting device for a substation of the present invention has a base 2 on which a lifting boom 1 is installed for lifting electrical equipment. A cantilever hanger 7 is connected to the top of the lifting suspender 1 through a rotating member, and the cantilever hanger 7 is provided with a suspension rope hook 5 for hanging electrical equipment 6 . One side of the base 2 is hinged with a mobile trolley 3 for transferring the lifting device, and the mobile trolley 3 is connected with a boom vertical liquid cylinder 4 connected with the lifting boom 1 for vertical lifting of the lifting boom 1. up and down. The lifting boom 1 adopts one-stage or multi-stage lifting hydraulic cylinders according to the needs of the substation, which is more convenient for lifting. The lifting cylinder and the boom vertical cylinder 4 are matched with an oil pump and a control box. The lifting boom 1 is provided with 1 to 3 positioning hoops 8 for connecting the installation foundation column 9 of the electrical equipment 6, which can fix the lifting suspension rod 1 and the installation foundation column 9 of the installation electrical equipment 6 together, and can The stability of lifting boom 1 hoisting operation.
本发明的变电站用轻便起吊装置在使用时，可推动移动小车3和待安装电气设备6分别移至安装基础柱9近旁，操纵吊杆立放液缸4使升降吊杆1抬起至直立状态，并通过定位抱箍8将升降吊杆1和安装基础柱9固定在一起。此时，将待安装电气设备6悬挂连接在所述悬绳挂接件5上，操纵升降液缸升起，并转动悬臂吊架7使待安装电气设备6靠近安装基础柱9，即可将待安装电气设备6起升至安装高度。通过升降液缸的升降调整，操作人员攀至安装基础柱9上部即能将待安装电气设备6方便地连接固定在安装基础柱9上。安装完毕后，收缩升降液缸，摘掉悬绳，再通过吊杆立放液缸4使升降吊杆1叠摞在所述移动小车3上，移至存放位置即可。待该变电站用轻便起吊装置起吊占用场地及空间位置小，因而不受现场条件限制和上方带电母线的影响，作业更换或安装电气设备时无需大范围停电，而且操作十分方便，安全可靠，由此使作业效率大大提高，配合人员数量可以大大减少。 When the portable lifting device for a substation of the present invention is in use, the mobile trolley 3 and the electrical equipment 6 to be installed can be moved to the vicinity of the installation foundation column 9 respectively, and the lifting boom 1 can be lifted to an upright state by manipulating the vertical lifting cylinder 4 of the boom , and fix the lifting boom 1 and the installation foundation column 9 together by positioning the hoop 8 . At this time, the electrical equipment 6 to be installed is suspended and connected to the hanging rope hook 5, the lifting cylinder is manipulated to rise, and the cantilever hanger 7 is rotated so that the electrical equipment 6 to be installed is close to the installation foundation column 9, and the installation can be completed. The electrical equipment 6 to be installed rises to the installation height. Through the lifting adjustment of the lifting cylinder, the operator can easily connect and fix the electrical equipment 6 to be installed on the installation base column 9 by climbing to the top of the installation base column 9 . After the installation is completed, shrink the lifting cylinder, take off the suspension rope, and then make the lifting boom 1 stack on the mobile trolley 3 through the vertical lifting cylinder 4, and then move to the storage position. The site and space occupied by the portable lifting device for the substation are small, so it is not affected by site conditions and the live busbar above, and there is no need for large-scale power outages when replacing or installing electrical equipment, and the operation is very convenient, safe and reliable. The operating efficiency is greatly improved, and the number of cooperating personnel can be greatly reduced.
