Small pneumatic vehicle used in fire scene

Abstract

The invention relates to a small pneumatic vehicle used in a fire scene, which has the technical scheme that an air source joint [4] arranged at the tail part of a vehicle body [23] is connected with a valve opening P of an electromagnetic valve block [14] through a high-pressure air pipe via an energy accumulator [19], a valve opening B and a valve opening C of the electromagnetic valve block [14] are respectively connected with two air holes of a pneumatic motor [12] through high-pressure air pipes, the valve opening A of the electromagnetic valve block [14] is connected with a clutch [6] through a high-pressure air pipe, a valve opening L and a valve opening R of the electromagnetic valve block [14] are respectively connected with a left braking air cylinder [11] and a right braking air cylinder [20] through high-pressure gas pipes, the pneumatic motor [12] respectively drives a left side driving shaft [8] and a right side driving shaft [1] of the small vehicle through the clutch [6], a speed reducer [5] and a differential mechanism [3], a remote controller [17] is in wireless connection with a signal receiving and control module [16], and the signal receiving and control module [16] is connected with the electromagnetic valve block [14] through a cable [15]. The invention has the characteristics that the small pneumatic vehicle is applicable to the dangerous environment such as high-temperature environment, the explosive environment and the like, and the safety of firefighters can be ensured.

Description

technical field [0001] The invention belongs to the technical field of pneumatic trolleys. Specifically relates to a pneumatic trolley for fire scene. Background technique [0002] At present, the transfer of materials and equipment at the fire scene is mostly realized by the manpower of firefighters, so firefighters must often enter and exit the fire scene. The main disadvantages of the method are: 1. It increases the labor intensity of firefighters, which makes them tired and reduces disaster relief efficiency and quality; . [0003] Although more mature highly integrated and highly intelligent fire-fighting robots have appeared, judging from the current usage, there are still some disadvantages: 1. It is driven by a motor, the vehicle-mounted power supply is bulky and the electrical control equipment increases its own weight, which is not suitable for High temperature, explosive and other disaster environments; Second, the price is expensive, the structure is complicat...
