摘要：【中文】本发明创造提供一种可伸缩型罐体大孔洞封堵工具，包括支撑杆、顶部联动块、前滑动块、后滑动块和若干前联动杆组和若干后联动杆组；所述顶部联动块设置在所述支撑杆的端部，所述前滑动块、后滑动块依次套在包括支撑杆上。本发明创造的有益效果是：可以针对大尺寸和不规则罐体表面及端面，快速进行固定及定位，避免因为局部不规则或者壁厚过薄造成无法进行封堵的情况。封堵完成后，等介质都排空，还可以方便拆卸，可折叠起来进行回收，不需要特殊工具进行拆卸。 【EN】The invention provides a telescopic tank body large hole plugging tool, which comprises a supporting rod, a top linkage block, a front sliding block, a rear sliding block, a plurality of front linkage rod groups and a plurality of rear linkage rod groups, wherein the top linkage block is arranged on the top of the supporting rod; the top linkage block is arranged at the end part of the supporting rod, and the front sliding block and the rear sliding block are sequentially sleeved on the supporting rod. The beneficial effects of the invention are as follows: can be directed against the surface and the terminal surface of jumbo size and irregular jar body, fix and fix a position fast, avoid because local irregularity or the wall thickness is too thin leads to the fact the condition that can't carry out the shutoff. After plugging is completed, the medium is emptied, the plugging device can be conveniently disassembled, and can be folded to be recovered without disassembling by special tools.

摘要：【中文】本发明创造提供一种带压堵漏拉紧装置，包括主体支架、主轴、锁紧滑块和前索具；所述主体支架的底端和顶端分别设置有轴承孔A和轴承孔B，所述主轴的顶端穿过所述轴承孔A，伸入所述轴承孔B中，所述主轴的中部设置有外螺纹，并穿过带有相应内螺纹的所述锁紧滑块；所述主体支架的顶端设置有所述前索具，所述前索具上设置有索具带孔B,所述索具带孔B的外侧设置有多个紧固螺钉B。本发明创造的有益效果是：本技术方案是一种安全可靠、紧凑简单的机械结构，实现对钢丝绳索具带的有效拉紧；并通过结构减小使用中的摩擦力，达到省力效果；同时能与现有封堵工具相配合，以在部分危化品泄漏封堵场景中替代液压拉紧器。 【EN】The invention provides a pressurized leaking stoppage tensioning device, which comprises a main body bracket, a main shaft, a locking slide block and a front rigging; the bottom end and the top end of the main body support are respectively provided with a bearing hole A and a bearing hole B, the top end of the main shaft penetrates through the bearing hole A and extends into the bearing hole B, and the middle part of the main shaft is provided with an external thread and penetrates through the locking sliding block with a corresponding internal thread; the top end of the main body support is provided with the front rigging, the front rigging is provided with a rigging hole B, and the outer side of the rigging hole B is provided with a plurality of fastening screws B. The beneficial effects of the invention are as follows: the technical scheme is a safe, reliable, compact and simple mechanical structure, and realizes effective tensioning of the steel wire rope rigging belt; the friction force in use is reduced through the structure, and the labor-saving effect is achieved; meanwhile, the plugging tool can be matched with the existing plugging tool to replace a hydraulic tensioner in a partial dangerous chemical leakage plugging scene.
