Description
技术领域 technical field
本实用新型涉及一种电力系统套管吊装专用工具,属于起重机吊具技术领域。 The utility model relates to a special tool for hoisting a power system bushing, which belongs to the technical field of crane spreaders.
背景技术 Background technique
电力系统的变压器安装及维护时,经常会遇到变压器套管的拆装问题,一般套管的拆装是通过吊装设备的配合完成的。在油纸电容式套管由水平放置状态起吊至竖立状态过程中,位于套管底部的均压球受力很大,为了防止均压球损伤和控制套管正常吊起,需要用粗绳环绕均压球上部,人为施力使均压球脱离包装箱箱底,由于人为施力与吊车施力的配合难以默契,使得套管起吊时均压球由于受力不均而被损坏的现象时有发生,在CT的吊装过程中也存在相同的问题;另外上述吊装方法还存在着作业时间长、需要操作人员数量多等缺陷。 During the installation and maintenance of transformers in power systems, disassembly and assembly of transformer bushings are often encountered. Generally, the disassembly and assembly of bushings is completed through the cooperation of hoisting equipment. When the oil-paper capacitive bushing is hoisted from a horizontal state to an upright state, the pressure equalizing ball at the bottom of the bushing is subjected to a large force. On the upper part of the pressure ball, artificial force is applied to make the pressure equalizing ball break away from the bottom of the packing box. Since the cooperation between the artificial force and the force of the crane is difficult to tacitly cooperate, the phenomenon that the pressure equalizing ball is damaged due to uneven force when the casing is hoisted occurs from time to time. , the same problem also exists in the hoisting process of CT; in addition, the above-mentioned hoisting method also has defects such as long operation time and a large number of operators.
实用新型内容 Utility model content
本实用新型的目的在于针对现有技术之弊端,提供一种结构简单、操作方便、能有效避免套管吊装过程中零部件损伤现象发生的套管吊装专用工具。 The purpose of the utility model is to provide a special casing hoisting tool which is simple in structure, easy to operate, and can effectively avoid damage to parts during the casing hoisting process.
本实用新型所述问题是以下述技术方案实现的: Problem described in the utility model is realized with following technical scheme:
一种套管吊装专用工具,它包括滑车和固定板,所述滑车与套管底部配装,所述固定板安装在套管顶部,套管吊绳穿过固定板后与套管法兰吊环连接。 A special tool for casing hoisting, which includes a pulley and a fixing plate, the pulley is fitted with the bottom of the casing, the fixing plate is installed on the top of the casing, the casing lifting rope passes through the fixing plate and connects with the casing flange ring connect.
上述套管吊装专用工具,所述滑车由套管定位柱、支撑架和两个橡塑轮组成,所述套管定位柱一端固定在支撑架上,另一端穿入套管尾部的铜导管内,所述支撑架包括矩形结构的支撑板和固定在支撑板下面的橡塑轮安装座,在支撑板的上面设有缓冲胶皮,所述橡塑轮通过轮轴销固定在橡塑轮安装座上。 The above special tool for casing hoisting, the trolley is composed of a casing positioning column, a support frame and two rubber and plastic wheels, one end of the casing positioning column is fixed on the support frame, and the other end penetrates into the copper conduit at the tail of the casing , the support frame includes a support plate with a rectangular structure and a rubber-plastic wheel mounting seat fixed under the support plate, a buffer rubber is arranged on the support plate, and the rubber-plastic wheel is fixed on the rubber-plastic wheel mounting seat through a wheel shaft pin .
上述套管吊装专用工具,所述固定板为菱形板结构,在其中心位置设有与套管顶部匹配的装配孔,在其两侧分别设置供吊绳穿过的吊装孔。 In the above-mentioned special tool for hoisting casing, the fixing plate is a diamond-shaped plate structure, and an assembly hole matching the top of the casing is provided at its center, and hoisting holes for the sling to pass are respectively arranged on both sides thereof.
本实用新型通过固定板上的吊装孔限定了吊绳在起吊过程中施加于套管法兰吊环上拉力的方向;通过滑车橡塑轮的滚动配合套管由水平放置状态至竖立的空间旋转动作;在滑车的支撑板上设置了缓冲胶皮,并将套管定位柱插入套管尾部的铜导管内;以上措施充分保证了套管在吊装过程中受力平稳,不发生磕碰等异常现象,使套管(或CT)安全就位。本实用新型结构简单,操作方便,不仅能保证套管(或CT)的平稳吊装,而且缩短了作业时间,减少了操作人员数量(只需两人即可完成套管吊装),提高了工作效率。 The utility model limits the direction of the pulling force that the lifting rope exerts on the casing flange ring during the lifting process through the hoisting hole on the fixing plate; the rolling of the rubber and plastic wheel of the pulley cooperates with the casing casing to rotate from the horizontal state to the vertical space. ;A buffer rubber is set on the support plate of the block, and the casing positioning column is inserted into the copper conduit at the end of the casing; the above measures fully ensure that the casing is under stable force during hoisting, and no abnormal phenomena such as bumps occur. The cannula (or CT) is securely in place. The utility model has the advantages of simple structure and convenient operation, which can not only ensure the stable hoisting of the casing (or CT), but also shorten the working time, reduce the number of operators (only two people can complete the casing hoisting), and improve the working efficiency .
