Problems solved by technology
[0002] At present, there are many kinds of rescue cutting machines on the market, most of which are small-sized, hand-held mechanical cutting machines. They cannot control the cutting accuracy, the profiling effect is poor, and they generate a lot of heat when cutting.
When it is used to rescue people buried under buildings, if it is not grasped properly, it is easy to cause accidental injury to the buried people, especially when the trapped people are trapped in a small space, and the objects that need to be demolished are closely attached to each other. Rescue cutting is almost impossible when attached to a trapped person, in addition, rescue cutting is currently inefficient and wastes a lot of valuable time

Embodiment 1
[0042] combine Figure 1 to Figure 7 As shown, the fast rescue cutting device includes a mobile cutting platform 1, a controller 6, an annular trajectory cutting mechanism 4, a vacuum adsorption mechanism 3 and a water recovery mechanism 2, and the annular trajectory cutting mechanism 4 includes a water storage tank 412, an abrasive box 422. High-pressure water pump 41 and cutting spray gun 48. The vacuum adsorption mechanism 3 includes a vacuum generator 32, a mechanical arm 5, and a vacuum cavity 38. The water recovery mechanism 2 includes a water pump 22, an annular water inlet 25, and a filter 21 , when a trapped person is found, the buried object on the upper part of the trapped person is sucked by the vacuum cavity 38 first, and then a circular rescue passage is cut out by the circular trajectory cutting mechanism 4, and the The water recycling mechanism 2 reclaims most of the water produced by cutting, and finally the mechanical arm 5 removes the cut objects to open a r...

The invention discloses an abrasive jet rapid cutting device which comprises a movable cutting platform. A mechanical arm is arranged on the movable cutting platform, an operation head is arranged atthe end of the mechanical arm, and the operation head comprises a vacuum adsorption mechanism and an annular trajectory cutting mechanism, wherein the vacuum adsorption mechanism is used for adsorbingan object to be cut, and the annular trajectory cutting mechanism is used for spraying abrasive water jet around the adsorption position of the vacuum adsorption mechanism to form an annular cuttingtrajectory. By means of the adsorption and cutting combined way, small-area efficient cutting can be achieved, rescue time and cutting workload are reduced, rescue efficiency is improved, and meanwhile the abrasive jet rapid cutting device is simple in structure, easy to achieve, high in cutting efficiency, free of heating in the cutting process, capable of cutting complex objects, suitable for being applied and popularized in rescue for products to be cut accordingly, and good in application prospect.
Description
technical field [0001] The invention relates to a rescue cutting machine, in particular to an abrasive jet rapid cutting device. Background technique [0002] There are many kinds of rescue cutting machines on the market, most of which are small-sized, hand-held mechanical cutting machines. They cannot control the cutting accuracy, have poor profiling effect, and generate a lot of heat during cutting. When it is used to rescue people buried under buildings, if it is not grasped properly, it is easy to cause accidental injury to the buried people, especially when the trapped people are trapped in a small space, and the objects that need to be demolished are closely attached to each other. Rescue cutting is almost impossible when attached to a trapped person, and in addition, rescue cutting is currently inefficient and wastes a lot of valuable time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an abrasive jet r...
