[0015] In the figure: 1 column frame, 2 ladder step frame, 3 pad, 4 included angle, 5 cross beam, 6 horizontal support, 7 inclined support, 8 pin, 81 pin hole, 9 fixed square tube, 91 "L" type bracket, 10 water cannon, 11 camera probe, 12 fire ladder stand, 13 fire ladder step, 14 roller, 15 roller shaft. DETAILED DESCRIPTION

[0016] The embodiment is a fire remote control water cannon bracket for metal ladder, as shown in the accompanying Figure 1 to the accompanying Figure 3 Two column frames 1 and a ladder step frame 2 made of U-shaped channel steel are fixedly connected into an H-shaped structure, the grooves of the U-shaped channel steel are all directed to the left side, and can be matchedly buckled on the first ladder step of the upper part of the metal ladder; the right side of the top of each of the two column frames 1 is fixedly connected with a pad 3, the right side of the pad 3 is fixedly connected with a cross beam 5, one end of each of the two ends of the right side of the cross beam 5 is fixedly connected with one end of a horizontal support 6, thereby forming a horizontal "N" type bracket, the base of the fire water cannon 10 is fixedly connected with the "N" type bracket, the included angle 4 between the horizontal support 6 and the column frame 1 is less than 90°, one end of each of two inclined supports 7 is fixedly connected with the right side of the ladder step frame 2, and the other end is fixedly connected with the other end of the horizontal support 6, and the middle upper part of each of the two column frames 1 is provided with a pin hole 81.

[0017] The fixed connection pad 3 is used to accurately position the left and right positions and height of the cross beam 5 and the two horizontal supports 6, and then accurately position the base of the remote control fire monitor 10. The position of the fire monitor 10 cannot be too left or right, otherwise the center of gravity will be unstable. If the position of the fire monitor 10 is too high, it will not be easy to operate when the height of the window of a building is not enough. If the position of the fire monitor 10 is too low, it will conflict with the top roller 14 of the fire ladder and the top end of the fire ladder stand 12. The included angle 4 between the horizontal support 6 and the column frame 1 is 70°-75°. The height of the cross beam 5 is flush with the height of the ladder roller 14.

[0018] The ladder step frame 2 is located at the lower position of the H-shaped structure, that is, the lower third of the two column frames 1. The U-shaped ladder step frame 2 has a groove facing the left side, and the H-shaped structure can be buckled on the top end of the metal fire ladder. The two U-shaped column frames 1 are buckled on the fire ladder stand 12, and the U-shaped ladder step frame 2 is buckled on the fire ladder step 13.

[0019] There are two pin holes 81 through the upper third of the two column frames 1, and the corresponding positions on the top of the ladder also have pin holes 81 through them, which can accommodate the insertion of the pin 8. By using this pin 8 pin hole 81 installation method, the stable connection of the bracket water monitor and the metal ladder can be quickly realized.

[0020] Two hollow fixed square tubes 9 are fixed along the front side of the horizontal support 6, and the "L" type bracket 91 is inserted into the fixed square tube 9 and fixed with small nails or screws. The "L" type bracket 91 is used to install the camera probe 11, and the situation of the fire scene can be seen on the ground screen, and the water spraying angle of the fire monitor 10 is adjusted by the remote control of the ground firefighter to spray water to the specified fire source.

[0021] The upper groove opening direction of the column frame 1 is matched with a notch larger than the diameter of the ladder roller shaft 15, which is used to avoid the wheel shaft end of the roller 14 at the top end of the metal ladder.

[0022] The important feature of the utility model is that it is easy to install and practical, and is suitable for uneven ground, and is used in fire fighting sites where the installation of fire fighting equipment space high class fire fighting vehicles cannot reach, so that the firefighters can quickly install the fire monitor on the first ladder step of the metal ladder.

[0023] After the fire monitor is fixed on the metal ladder, the ground firefighter can perform omnidirectional observation and omnidirectional high-altitude water spraying through remote control, solve the limitations of high-altitude fire fighting vehicles, and replace the high-altitude operation of fire rescue personnel, reduce the risk of injury and death of fire rescue personnel, and more effectively perform fire extinguishing and rescue for a long time.
