Embodiment Construction
[0050] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0051] see Figure 1 to Figure 6 , the invention discloses a boom structure of a fluid delivery device, comprising: a first angle sensor 2, a second angle sensor 3, a control unit, a multi-stage telescopic arm 4 and a wire winch structure 5;
[0052] The multi-stage telescopic arm 4 is extended or contracted along its own axis; the first angle sensor 2 and the second angle sensor 3 are respectively placed on different stages of the multi-stage telescopic arm;
[0053] The wire winch structure 5 includes a winch 50, a support arm 52, a pulley 53 and a wire rope 51; Connected by the steel wire rope 51, the support arm 52 is arranged on the multi-stage telescopic arm 4, and the end of the support arm 52 away from the multi-stage telesco...

The invention discloses an arm support structure of a fluid conveying device. One end of a multi-stage telescopic arm is movably connected with a swing mechanism; a first angle sensor and a second angle sensor are respectively arranged at two ends of the multi-stage telescopic arm; the winch is arranged at one end, close to the swing mechanism, of the multi-stage telescopic arm; one end, far away from the swing mechanism, of the multi-stage telescopic arm is connected with the winch through a steel wire rope; when the multi-stage telescopic arm extends, the first angle sensor and the second angle sensor detect the angle values of the two ends of the multi-stage telescopic arm; the control unit calculates the difference between the two angle values and judges whether the difference between the two angle values is larger than a first preset angle value or not; and if the difference between the two angle values is larger than the first preset angle value, the control unit drives the winch to tighten the steel wire rope. Through the arrangement of a steel wire winch structure, a control unit, a first angle sensor and a second angle sensor, when the multi-stage telescopic arm extends outwards, the end, far away from the swing mechanism, of the multi-stage telescopic arm is prevented from being bent downwards; and meanwhile, the lifting height of the multi-stage telescopic arm is increased.
Description
technical field [0001] The invention relates to the technical field of fire protection, in particular to a boom structure of a fluid delivery device and a fire truck. Background technique [0002] In the prior art, in the case of fire extinguishing in a high-rise building, a foldable fire extinguisher is used, and the foldable fire extinguisher requires a relatively large high-altitude working space. When the folding fire extinguisher is in use, it is necessary to extend the four fixing brackets at the bottom, and then start folding and stretching after the fixing brackets are fixed; when folding, the folding arm needs to be unfolded first, and then the fire extinguishing mechanism is delivered to the designated fire extinguishing position. Start the infusion to put out the fire. [0003] In the prior art, there are following deficiencies: [0004] 1) When the inner tube is stretched out, the end of the multi-stage telescopic arm away from the slewing mechanism will bend d...
