The invention discloses a method for overhauling a boiler wall hole door. At present, when a maintainer enters a hearth for maintenance, a radial blind plate needs to be opened and then enters the hearth through a short barrel section, and due to the fact that the size of the short barrel section is limited, much inconvenience is brought when the maintainer enters the hearth. The method comprises the following steps that a temporary hanging bracket is composed of a side supporting frame, a roller assembly and a conveying belt, a hanging ring is welded to the top of a handrail frame, and a lower spring buckle is arranged in the hanging ring in a sleeved mode; firstly, a maintainer enters a hearth from a short barrel section, hangs an upper spring buckle on a pull ring and lifts a temporary hanging bracket through the pull ring and a pull rope; during maintenance, the handle frame is pulled, the roller assembly on the conveying belt is used for conveying maintenance personnel into the hearth, the maintenance equipment is pushed to be conveyed into the hearth through the roller assembly, the maintenance personnel in the hearth carry out response, and the maintenance equipment can be rapidly conveyed into the hearth. The invention is applied to the thermoelectric field.
一种检修锅炉炉壁孔门的方法。目前,检修人员在进入炉膛进行检修时,需要径盲板打开后通过短筒节进入到炉膛,由于短筒节的尺寸有限,检修人员在进入到炉膛中带来诸多不便。本发明包括如下步骤:由侧支撑架、滚筒组件和输送带组成临时吊架,在扶手架的顶部焊接有吊环,吊环中套入有下弹簧扣;首先一名检修人员先从短筒节进入到炉膛内部,检修人员将上弹簧卡扣挂靠在拉环上,通过拉环和拉绳将临时吊架吊起;拉动扶手架,通过输送带上的滚筒组件将检修人员送入到炉膛内,推动检修设备通过滚筒组件将检修设备送入到炉膛内,由炉膛内的检修人员进行接应,能够快速安装的将维修设备送入到炉膛内。本发明应用于热电领域。
