Problems solved by technology

[0004] 1. When a fire occurs in the pipeline, the situation at the valve is complicated and difficult to observe
[0005] 2. There is also a fire at the valve, and it is difficult for people to get close, and the valve cannot be closed, and the fire may spread further
[0006] 3. Existing robots mainly focus on ground fire fighting and detection, and there is no dedicated automatic valve closing device

Embodiment Construction

[0022] The invention as figure 1 , 2 As shown, the main components are input shaft 1, T-axis connector 2, input bevel gear 3, connector 4, end cover I5, high temperature resistant camera 6, output bevel gear 7, output shaft connector 8, output shaft 9, end Cover II 10, baffle plate 11, cover 12, key 13, tapered roller bearing 14, rack pressure plate 15, lower clamp body 16, upper clamp body 17, gear 18, etc. There is a spline groove in the input shaft 1 to connect with the input shaft of the external robot to transmit the main motion. The T-axis connecting body 2 is connected with the T-axis of the external robot through bolts, and drives the entire end effector to rotate 360° around the T-axis. The input bevel gear 3 and the output bevel gear 7 play the role of transmitting the rotary motion of the input shaft 1, and are respectively connected with the input shaft 1 and the output shaft 9 through the key 13, and the end cover I5 plays a role of restricting the input bevel g...

Abstract

The invention discloses an end effector of a fire-fighting robot for closing a fire valve. The input bevel gear and the output bevel gear are meshed, and are respectively connected to the input shaft and the output shaft through a key. The gear is connected to the other end of the output shaft through a key. The upper clamps are L-shaped respectively, and the upper part is processed with racks that mesh with the left and right sides of the gears respectively; the high temperature resistant camera is connected to the connecting body through threads. The invention realizes the switch of the valve by clamping the valve handle and rotating around the center of the valve. The invention cooperates with the robot to realize the three-dimensional movement without dead angle, and has wide applicability, and is suitable for common valves such as ball valves, butterfly valves, and stop valves; The relative movement can shorten the clamping time by one time; it can effectively solve the problem that the valves of flammable and explosive pipelines cannot be closed in case of fire.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting robots, and relates to a fire-fighting robot end effector for closing the valves of flammable and explosive pipelines when a fire occurs. Background technique [0002] With the development of science and technology, fire-fighting robots have been gradually popularized. Fire-fighting robots play a very important role in coping with complex terrain and performing special tasks, especially in severe fires. At present, the mainstream fire-fighting robots are mainly ground fire-fighting robots and aerial reconnaissance robots. Most of the ground-based fire-fighting robots are based on the traditional water gun clamping type, mainly responsible for fire-fighting tasks, and aerial reconnaissance robots are mainly responsible for fire detection and investigation tasks. But there are many types of fires, and the problems that need to be dealt with first are also very different. For example, when a fi...
