Description

Technical Field

[0001] The utility model relates to the technical field of water supply for trains, in particular to a water supply device with a power-off automatic reset function. Background Art

[0002] Water on trains is provided by water tanks. Due to the limited capacity of water tanks on trains and the large amount of water used by passengers on trains, trains usually need to be refilled with water at some stations where they stay for a long time to ensure the water needs of passengers. At present, intelligent passenger car water supply devices have been popularized in most stations in my country. The device can realize functions such as electric pipe collection, remote control of water supply and water stop, and automatic heating in winter.

[0003] The intelligent water supply device usually includes a robot and a water injection gun. The robot drives the water injection gun to connect with the water injection port of the train water tank through the robot arm, so as to achieve water supply. After the water supply is completed, the robot's mechanical arm drives the water injection gun to separate from the water injection port of the train water tank and reset. In the existing intelligent water supply device, the mechanical arm is electrically controlled by the robot. When the robot is powered off, the extended mechanical arm cannot be retracted. If the mechanical arm cannot be retracted before the train starts, it is easy to interfere with the operation of the train. The force exerted by the moving train on the mechanical arm is easy to cause damage to the mechanical arm or even the robot. Utility Model Content

[0004] In order to overcome the defects in the prior art, an embodiment of the utility model provides a water supply device with an automatic reset function in case of power failure, which is used to solve the above-mentioned problems.

[0005] The embodiment of the present application discloses: a water supply device with an automatic reset function in case of power failure, comprising: a robot body, a motor, a mechanical arm, a water injection gun and an automatic reset mechanism, wherein the motor is arranged on the robot body, one end of the mechanical arm is connected to the motor, the water injection gun is connected to an end of the mechanical arm away from the motor, and the automatic reset mechanism is arranged on the robot body and connected to the mechanical arm.

[0006] Specifically, the automatic reset mechanism includes a gas spring and a first reset rod, one end of the gas spring is connected to the robot body, and the other end is connected to the first reset rod, and the end of the first reset rod facing away from the gas spring is connected to the robot arm.

[0007] Specifically, the robotic arm includes a first bracket, a second bracket, a first connecting rod, and a second connecting rod. The first bracket is connected to the robot body. Both ends of the first connecting rod are hinged to the first bracket and the second bracket respectively. One end of the second connecting rod is hinged to the second bracket, and the other end is connected to the output shaft of the motor. The first connecting rod and the second connecting rod are parallel. The water injection gun is installed on the second bracket, and the second connecting rod is connected to the first reset rod.

[0008] Specifically, the automatic reset mechanism further includes a second reset rod. One end of the second reset rod is connected to the gas spring, and the other end is connected to the robot body.

[0009] Specifically, the first bracket and the second bracket are provided with weight-reducing holes.

[0010] Specifically, the device further includes a speed reducer, and the speed reducer is connected to the motor.

[0011] The utility model has at least the following beneficial effects:

[0012] 1. An automatic reset mechanism is provided on the robot body of the water supply device with a power-off automatic reset function in this embodiment. The automatic reset mechanism is connected to the robotic arm. The automatic reset mechanism adopts a non-electric power source. When the motor drives the robotic arm to extend, the automatic reset mechanism is in a stretched state. When the robot suddenly loses power, the automatic reset mechanism contracts and pulls the robotic arm towards the robot body to move, realizing the retraction of the robotic arm in the power-off state, which can avoid the interference of the robotic arm with the train's driving and thus avoid the damage of the robotic arm.

[0013] 2. When the gas spring retracts and pulls the first reset rod and the second reset rod to drive the robotic arm to quickly descend, a reaction force will be generated when the stroke of the gas spring approaches the initial position to achieve a buffering effect, avoiding the impact between the robotic arm and the robot body and being damaged.

[0022] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0023] like Figure 1 As shown, the water supply device with power-off automatic reset function of this embodiment mainly includes a robot body 1, a motor 2, a mechanical arm, a water injection gun 4 and an automatic reset mechanism. Among them, the robot body 1 is used to provide the main operating system of the entire device; the motor 2 is arranged on the robot body 1, and is used to drive the mechanical arm to extend and retract. Preferably, the motor 2 adopts a servo motor 2 with high control accuracy; one end of the mechanical arm is connected to the motor 2, and the water injection gun 4 is connected to the end of the mechanical arm away from the motor 2; the automatic reset mechanism is arranged on the robot body 1 and connected to the mechanical arm.

[0024] By adopting the above scheme, an automatic reset mechanism is provided on the robot body 1 of the water supply device with automatic reset function in case of power failure in this embodiment. The automatic reset mechanism is connected to the robotic arm. The automatic reset mechanism adopts a non-electrical power source. When the motor 2 drives the robotic arm to extend, the automatic reset mechanism is in a stretched state. When the robot suddenly loses power, the automatic reset mechanism contracts and pulls the robotic arm toward the robot body 1, thereby realizing the retraction of the robotic arm in the power-off state, which can avoid the robotic arm from interfering with the travel of the train, thereby avoiding damage to the robotic arm.

[0025] Specifically, Figure 1 The reset mechanism of this embodiment includes a gas spring 51 and a first reset rod 52. One end of the gas spring 51 is connected to the robot body 1, the other end of the gas spring 51 is connected to the first reset rod 52, and the end of the first reset rod 52 away from the gas spring 51 is connected to the robot arm. More specifically, the gas spring 51 and the first reset rod 52 are arranged below the robot arm.

[0026] like Figure 1As shown in the figure, the robotic arm of this embodiment includes a first bracket 31, a second bracket 32, a first connecting rod 33, and a second connecting rod 34. The first bracket 31 is connected to the robot body 1 and can support the entire robotic arm when the robotic arm extends; the second bracket 32 is arranged opposite to the first bracket 31 and is used to install a column water gun; one end of the first connecting rod 33 is hinged to the first bracket 31 and the other end is hinged to the second bracket 32; one end of the second connecting rod 34 is hinged to the second bracket 32 and the other end is connected to the output shaft of the motor 2, and the first connecting rod 33 and the second connecting rod 34 are arranged in parallel. That is to say, the first bracket 31, the second bracket 32, the first connecting rod 33, and the second connecting rod 34 are connected to form a four-bar mechanism. When the motor 2 drives the second connecting rod 34 to rotate, the first connecting rod 33 can be driven to move, realizing the extension and retraction of the robotic arm. The second connecting rod 34 is connected to the first reset rod 52 of the automatic reset mechanism. When the gas spring 51 retracts, the first reset rod 52 can drive the second connecting rod 34 to move towards the robot body 1, and then drive the entire robotic arm to move towards the robot body 1.

[0027] As Figure 1 shown in the figure, the automatic reset mechanism of this embodiment may further include a second reset rod 53. One end of the second reset rod 53 is connected to the gas spring 51 and the other end is connected to the robot body 1. Specifically, the second reset rod 53 and the first reset rod 52 are distributed on both sides of the gas spring 51, and the opposite ends of the two are simultaneously connected to the gas spring 51. With the above solution, when the gas spring 51 retracts and pulls the first reset rod 52 and the second reset rod 53 to drive the robotic arm to quickly descend, a reaction force will be generated when the stroke of the gas spring 51 approaches the initial position to achieve a buffering effect, avoiding damage to the robotic arm caused by hitting the robot body 1.

[0028] Preferably, the first bracket 31 and the second bracket 32 may also be provided with weight-reducing holes to reduce the load on the robot body 1 and the motor 2.

[0029] As Figure 1 shown in the figure, the device of this embodiment further includes a speed reducer 6. The speed reducer 6 is connected to the output end of the motor 2 and can be used to decelerate the telescoping of the robotic arm, improving the smoothness of the telescoping of the robotic arm.

[0030] In summary, the working process of the water supply device with power-off automatic reset function in this embodiment is as follows: when water supply is required, the motor 2 drives the second connecting rod 34 to rotate, driving the first connecting rod 33 to rotate, realizing the extension of the robotic arm. At the same time, the gas spring 51 is in a stretched state; when the water supply ends, the motor 2 drives the robotic arm to retract, and the gas spring 51 retracts and pulls the first reset rod 52 and the second reset rod 53, which can prompt the robotic arm to quickly retract; when the device suddenly loses power, the robotic arm can also be quickly retracted by the gas spring 51 retracting and pulling the first reset rod 52.

[0031] In the present utility model, specific embodiments are used to elaborate on the principles and implementation manners of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present utility model.
