Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The emergency brake device and the rail having the emergency brake device according to the embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 10, the emergency brake device according to the embodiment of the present invention includes a power supply system 3, a first spring 22, a trigger pin 21, a lever 13, a lever support 14, and an emergency switch 11. For convenience of description, the directions "up and down, left and right" are defined below with the directions of arrows in the drawings, wherein the direction "up and down" is a vertical direction, and the direction "left and right" is a horizontal direction.

As shown in fig. 1-2, the power supply system 3 includes a switch 31 and a power supply (not shown). The power supply system 3 is provided on the power supply box. The switch 31 is movably disposed between a closed position, in which the power is on, and a disengaged position, in which the power is off, when the switch 31 is in the closed position. The power supply refers to a traction power supply of an electric locomotive (such as a mining electric locomotive), the traction power supply provides driving force for the mining electric locomotive, meanwhile, a braking unit is arranged on the electric locomotive, and the power supply is turned off to stop providing traction for the electric locomotive and prompt a driver to start the braking unit to decelerate or scram the electric locomotive. That is, when the switch 31 is in the disengaged position, the power source is turned off, the electric locomotive loses traction, and the driver can be prompted to activate the brake unit on the electric locomotive to slow down or scram the electric locomotive. Brake units on electric locomotives are common in the art and will not be described in detail herein.

As shown in fig. 3-4, a first end of the first spring 22 is fixedly disposed, and a second end of the first spring 22 is connected to the switch 31. As an example, the length direction of the first spring 22 extends in the vertical direction, and the first end of the first spring 22 is located directly above the second end of the first spring 22. The first spring 22 is arranged to be switchable between a first state and a second state, i.e. the first spring 22 is switchable between the first state and the second state. The first state is a deformed state, and the second state is a natural state or a deformed state. The natural state of the first spring 22 refers to a state when it is not subjected to an external force, in which the first spring 22 does not have deformation. The deformed state of the first spring 22 refers to a state when it is acted upon by an external force.

By way of example, the length of the first spring 22 in the first state (shown in FIG. 3) is less than the length of the first spring 22 in the second state (shown in FIG. 4). That is, the first spring 22 in the first state is in a compressed state, the first spring 22 in the second state is in a natural state, or the first spring 22 in the second state is in a compressed state, and at this time, it is compressed to a smaller extent than the first spring 22 in the first state. For convenience of understanding, the following description will be given by taking the first state as a compressed state (as shown in fig. 3) and the second state as a natural state (as shown in fig. 4). The length of the first spring 22 as described herein refers to a linear distance from a first end to a second end of the first spring 22. Also, since the first end of the first spring 22 is fixedly disposed, the transition of the state of the first spring 22 is represented as the up-and-down movement of the second end of the first spring 22.

As shown in fig. 3, when the first spring 22 is in the first state, the switch 31 is in the closed position. As shown in fig. 4, when the first spring 22 is in the second state, the switch 31 is in the disengaged position. When the first spring 22 is switched from the first state to the second state, the first spring 22 drives the switch 31 to move from the closed position to the separated position. The movement of the switch 31 from the closed position to the open position is caused by the first spring 22 switching from the first state to the second state. This is due to the second end of the first spring 22 being connected to the switch 31. The movement of the second end of the first spring 22 in the vertical direction can directly result in a movement of the position of the (entraining) switch 31.

As shown in fig. 5, the trigger pin 21 is movably disposed between a stop position and a disengagement position. The trigger pin 21 located at the stop position cooperates with the first spring 22 to keep the first spring 22 in the first state. For example, the engagement between the trigger pin 21 and the first spring 22 means that the trigger pin 21 in the stop position is located below the second end of the first spring 22, and the first spring 22 is prevented from being shifted from the first state (i.e., the compressed state) to the second state (i.e., the natural state) to perform a stop function. The trigger pin 21 at the disengagement position disengages the first spring 22 so that the first spring 22 is changed from the first state to the second state. For example, when the trigger pin 21 is no longer located below the second end of the first spring 22, there is no action between the trigger pin 21 and the first spring 22, and the first spring 22 will transition from the first state (i.e., compressed state) to the second state (i.e., natural state) under its own elastic force.

As shown in fig. 8, the lever 13 is rotatably provided on the lever support 14. The lever 13 includes a first portion and a second portion, which are located on both sides of a fulcrum of the lever 13. The fulcrum of the lever 13 refers to the mounting position between the lever 13 and the lever support 14. The lever 13 is rotatable about the fulcrum. The first portion is connected to the trigger pin 21 by the first wire 12 so that the first portion moves the trigger pin 21 from the stop position to the disengaged position by the first wire 12. To which the emergency switch 11 is connected. As an example, the first and second portions of the lever 13 are located on the left and right sides of its fulcrum, respectively. As shown in fig. 5 and 8, both ends of the first wire 12 are connected to the left end of the lever 13 and the right end of the trigger pin 21, respectively.

The working process of the emergency braking device according to the embodiment of the present invention is described below by taking the emergency braking device in fig. 1 to 9 as an example.

When the emergency brake device is in the initial state (i.e., the open state), the trigger pin 21 is located at the stop position, the first spring 22 is maintained in the first state (i.e., the compressed state) by the trigger pin 21, and the switch 31 is located at the closed position. When the electric locomotive touches the emergency switch 11, the emergency switch 11 moves downward in the vertical direction, so that the lever 13 rotates clockwise around the pivot point thereof, and therefore the connection position of the first pull wire 12 and the lever 13 moves upward in the vertical direction. At this time, since the first wire 12 is connected to the right end of the trigger pin 21, the first wire 12 applies a right pulling force to the trigger pin 21, and the trigger pin 21 moves to the right by the pulling force. The trigger pin 21 is thus moved from the stop position to the disengagement position, the first spring 22 is switched from the first state to the second state, and the switch 31 is moved from the closed position to the disengaged position. When the switch 31 is moved to the separation position, the power supply is turned off, the electric locomotive loses traction, and a driver can be prompted to start the brake unit, so that the electric locomotive is decelerated or suddenly stopped.

According to the utility model discloses emergent arresting gear, it is the independent mechanical trigger device of a non-power supply, and simple structure is reliable, and the installation is nimble, and the operation is simple and convenient.
