Problems solved by technology

However, this kind of machine is only suitable for drilling operations with a maximum diameter of about 10 mm. If using its principle to open a channel with a diameter of about 500 mm, there will be many technical problems. , when cutting, the reaction force received by different cutter heads will be transmitted to the spindle, which will cause the spindle to swing, and the hole cannot be opened normally

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as figure 1 As shown, the present invention includes a motor 1 and a reducer 2 driven by the motor 1 , the output shaft of the reducer 2 is connected with a power transition shaft 3 . It also includes a cylindrical cutterhead sleeve 7 with a cutterhead 11 fixedly connected to its lower end. The cutterhead 11 is coaxially arranged with the cutterhead sleeve 7 and the cutterhead 11 has a central through hole whose inner diameter is substantially the same as that of the cutterhead sleeve 7 . The power transition shaft 3 penetrates into the cutter sleeve 7 from the upper port of the cutter sleeve 7 and is connected with the cutter sleeve 7 through a flat key. On the transition shaft 3 , the keyway of the flat key is axially opened on the inner wall of the cutter head sleeve 7 . Three knife rests 16 are installed on the outer edge of the cutter head 11 in a 120° un...

Abstract

The invention provides an emergency rescue quickly flameproof tapping device for turned ships in danger. A speed reducer (2) drives a knife flywheel (11) to rotate through a power transition shaft (3) and a knife flywheel sleeve (7), the power transition shaft (3) drives a feeding sleeve (6) to feed through a nut gear (12) and a speed reducing mechanism, the feeding sleeve (6) enables feeding reactive force to be transmitted to a casing through a rolling ball (17), a lifting magnet (13) is further installed on the knife flywheel (11), and the upper end of a connecting rod of the lifting magnet (13) is located in the space of the knife flywheel sleeve (7). The emergency rescue quickly flameproof tapping device for turned ships in danger reduces feeding power consumption, solves the problem of vertical cutting tool movement caused by feeding reduction gear clearance accumulation, and can finish tapping in about 10 minutes to provide a rescue channel from a ship plate.

Description

technical field [0001] The invention relates to an explosion-proof hole opening device. In particular, it relates to a quick explosion-proof opening device for emergency rescue for capsized ships in distress. Background technique [0002] A large number of ship capsizing dangers occur in the coast of my country every year. There are usually flammable and explosive gases in the capsized cabin. Open flames are used to open holes in the bottom of the ship, which is very prone to explosion, which endangers the safety of trapped people and rescuers. Therefore, the technology of opening holes without sparks to rescue people from steel capsized ships has become a major issue at present. In view of the characteristics of the dangerous situation of capsizing and arresting ships at sea, emergency rescue should meet the following requirements: First, open the life channel with a steel plate thickness not exceeding 20mm and a diameter of about 500mm in the shortest possible time. Seco...
