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

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 jet 41 and the second water jet 51 respectively, and the liquid nitrogen delivery pipelines are respectively It is communicated 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 the liquid nitrogen and the water jet respectively. When cutting, the water jet is first sprayed to the place to be cut. Liquid nitrogen, after cooling the explosives, the water jet is sprayed by the water jet for cutting, which reduces the number of structures and equipment costs.

Abstract

The invention relates to the field of explosion-proof equipment, in particular to a liquid nitrogen-assisted cooling water-cutting explosion-proof vehicle, which comprises an installation platform, a telescopic table, a first water jet and a second water jet, and the telescopic table is slidable in a horizontal plane Set on the installation platform, the first water jet and the second water jet are respectively set at both ends of the telescopic table along the moving direction; the first water jet is slidably mounted on the first linear sliding table, and the first straight The wire slide table is installed on the first turntable; the second water jet is arranged on the second turntable through the movable small arm and the movable large arm which are hinged in sequence. The invention adopts a multi-degree-of-freedom double water jet structure, which can effectively meet the destruction of explosives in various poses, and has a wide range of applications; at the same time when cutting, a pan-tilt is used to adjust the position and angle of the camera, and the cutting position and state are monitored in real time. , to ensure cutting accuracy and explosion safety; reduce the temperature at the cutting position through liquid nitrogen and water jets to prevent explosions.

Description

technical field [0001] The invention relates to the field of explosion-proof equipment, in particular to a liquid nitrogen-assisted 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 explosives and damage the protected target. In addition, most of the existing robot walking mechanisms are electric-driven crawler-type walking mechanisms and electric-driven wheel-type walking mechanisms, which require external design and installation of power transmiss...
