Problems solved by technology

This method has a low fault tolerance rate, and the robot must be controlled remotely by the operator. A little carelessness will detonate the explosives and damage the protected target.
In addition, most of the existing robot traveling mechanisms are electric-driven crawler-type traveling mechanisms and electric-driven wheel-type traveling mechanisms, which require external design and installation of power transmission mechanisms, such as gearboxes, motors, etc., which make the mobile chassis of the robot large in size and weight. Disadvantages such as poor mobility

Embodiment 1

[0031] Such as figure 1 As shown, a liquid nitrogen auxiliary cooling water cutting explosion-proof vehicle includes an installation platform 11, a telescopic table 21, a first water knife 41, a second water knife 51 and a liquid nitrogen cooling device, and four walking wheels are arranged on the installation platform 11. 12. Each traveling wheel 12 is separately driven, with simple structure and good interchangeability. The telescopic table 21 is slidably arranged on the installation platform 11 in the horizontal plane, preferably, as figure 2 As shown, the telescopic table linear module 22 is fixedly installed on the installation platform 11, and the telescopic table 21 is fixedly connected with the slider of the telescopic table linear module 22, and the telescopic table 21 is driven to move by the telescopic table linear module 22. Due to the certain weight of the telescopic table 21 and the equipment on it, in order to ensure the moving path of the telescopic table 21 ...

Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 is that the liquid nitrogen delivery pump 62 is connected to the liquid nitrogen delivery pipelines leading to the positions of the first water knife 41 and the second water knife 51 respectively, and the liquid nitrogen delivery pipelines are respectively It communicates with the first water jet 41 and the second water jet 51, so that both the first water jet 41 and the second water jet 51 can spray liquid nitrogen and water jet respectively. When cutting, the water jet first sprays to the place to be cut Liquid nitrogen, after cooling the explosives, is cut by a waterjet jet, which reduces the number of structures and reduces equipment costs.

Abstract

The invention relates to the field of explosion-proof equipment, in particular to a liquid nitrogen auxiliary cooling type water cutting explosion-proof vehicle which comprises a mounting platform, a telescopic table, a first water jet cutter and a second water jet cutter, the telescopic table is arranged on the mounting platform in a sliding mode in the horizontal plane, and the first water jet cutter and the second water jet cutter are arranged at the two ends of the telescopic table in the moving direction of the telescopic table respectively; the first water jet cutter is installed on a first linear sliding table in a sliding mode, and the first linear sliding table is installed on a first rotary table. And the second water jet cutter is arranged on a second rotary table through a movable small arm and a movable large arm which are hinged in sequence. A multi-degree-of-freedom double-water-jet-cutter structure is adopted, the requirement for damage to explosives in various poses can be effectively met, and the application range is wide; the position and the angle of the camera are adjusted by adopting a holder during cutting, and the cutting position and the cutting state are monitored in real time, so that the cutting precision and the explosive ordnance disposal safety are ensured; and the temperature of the cutting position is reduced through liquid nitrogen and water jet, and the explosion is prevented.

Description

technical field [0001] The invention relates to the field of explosion-proof equipment, in particular to a liquid nitrogen auxiliary cooling water cutting explosion-proof vehicle. Background technique [0002] At present, most of the existing EOD robots at home and abroad use crawler or wheeled walking mechanisms, and are equipped with manipulators. The way to remove explosives is to imitate human hands to grab explosives, change the spatial position of explosives, and keep the protected target away from the explosion. objects, thereby eliminating the danger. This method has a low fault tolerance rate, and the robot must be controlled by remote control through the operator. A little carelessness will detonate the explosives and damage the protected target. In addition, most of the existing robot traveling mechanisms are electric-driven crawler-type traveling mechanisms and electric-driven wheel-type traveling mechanisms, which require external design and installation of pow...
