Description

Technical Field

[0001] The utility model belongs to the technical field of brake auxiliary opening, and more specifically relates to a YEZ electric hydraulic drum brake auxiliary mechanism. Background Art

[0002] The YEZ electric hydraulic drum brake has no auxiliary opening device, and manual opening is difficult. There are problems such as slow opening action and failure to close the brake in one go. This causes damage to a series of equipment (melting of the brake mechanism, damage to the coupler seal, damage to the motor reducer oil seal, deterioration of the lubricating oil, annealing of the bearing), and even worse, the conveyor belt catches fire, causing a fire.

[0003] Therefore, it is necessary to design a device that can assist or replace manual opening and closing to ensure that the opening and closing of the switch is rapid and in place in one go. Utility Model Content

[0004] The utility model aims to provide a YEZ electric hydraulic drum brake auxiliary mechanism to solve the problems of slow opening and closing action and failure to reach the desired position at one time of the existing manual drive.

[0026] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] like Figure 1 As shown, a YEZ electric hydraulic drum brake auxiliary mechanism comprises:

[0028] A lifting mechanism 1, wherein a fixed end of the lifting mechanism 1 is connected to a base 9 of a brake 8;

[0029] A support arm 2, the support arm 2 is horizontally arranged, one end of the support arm 2 is connected to the lifting end of the lifting mechanism 1, and the other end of the support arm 2 is connected to the brake rod 7 of the brake 8;

[0030] The first limit switch 3 and the second limit switch 4 are vertically arranged with an interval, and a trigger block cooperating with the first limit switch 3 and the second limit switch 4 is arranged at the lifting end.

[0031] Specifically, the lifting mechanism 1 drives the brake rod 7 to move through the supporting arm 2, thereby controlling the opening and closing of the brake 8. The first limit switch 3 and the second limit switch 4 are respectively activated after being opened and closed, thereby notifying the lifting mechanism 1 to stop moving. It can assist or replace manual timely one-time completion of the opening and closing action, avoiding slow manual operation due to excessive impact, and failure to close or open the switch at one time.

[0032] In this embodiment, the trigger block includes:

[0033] The vertical pole has a first paddle 5 and a second paddle 6 arranged vertically at intervals on the vertical pole, and the first limit switch 3 and the second limit switch 4 are located between the first paddle 5 and the second paddle 6.

[0034] Specifically, this arrangement allows the first limit switch 3 and the second limit switch 4 to be installed close to each other, which is convenient for wiring maintenance.

[0035] In this embodiment, the first limit switch 3 and the second limit switch 4 are respectively arranged on both sides of the vertical pole, and the first paddle 5 and the second paddle 6 are oriented in opposite directions.

[0036] Specifically, the first paddle 5 and the second paddle 6 face oppositely to avoid interference.

[0037] In this embodiment, a controller is also included, and the controller is electrically connected to the lifting mechanism 1, the first limit switch 3 and the second limit switch 4.

[0038] Specifically, the controller is remotely controlled and operated via a communication unit.

[0039] In this embodiment, the lifting mechanism 1 includes a hydraulic cylinder, a mounting seat is provided on the hydraulic cylinder, and a first limit switch 3 and a second limit switch 4 are provided on the mounting seat.

[0040] Specifically, the support arm 2 is driven to move up and down by a hydraulic cylinder.

[0041] In this embodiment, the telescopic stroke of the hydraulic cylinder is greater than the movement stroke of the brake rod 7 .

[0042] Specifically, the telescopic stroke of the hydraulic cylinder is greater than the movement stroke of the brake rod 7, and cooperates with the first limit switch 3 and the second limit switch 4 to ensure that the brake 8 is opened and closed in place.

[0043] In this embodiment, the lower end of the brake 8 is arranged on the base 9 through a pedestal. The lower end of the base 9 is provided with a cavity. A hydraulic oil pump connected to the hydraulic oil cylinder is arranged in the cavity.

[0044] Specifically, the brake 8 is suspended in the air through the base 9 and used by the lifting mechanism 1, and the hydraulic oil pump is hidden in the cavity to avoid exposure of the hydraulic oil pump.

[0045] In this embodiment, a telescopic rod is also included. The telescopic rod is vertically arranged on a side of the base 9 away from the lifting mechanism 1, and the upper end of the telescopic rod is connected to the supporting arm 2 through a horizontal plate.

[0046] Specifically, the telescopic rod cooperates with the lifting mechanism 1 to form a door frame structure, ensuring stable movement of the supporting arm 2.

[0047] In this embodiment, the bracket arm 2 is a flat plate or a V-shaped plate.

[0048] Specifically, the flat support arm 2 needs to ensure strength and avoid bending, and the right-angle or acute-angle V-shaped support arm 2 has its tip pointed downward to reduce twisting force and withstand tension, thereby ensuring that the support arm 2 applies stable force to the brake rod 7.

[0049] In this embodiment, a temperature monitoring module is provided on a side of the supporting arm 2 or the lifting mechanism 1 close to the brake 8 .

[0050] Specifically, the temperature of the brake 8 is monitored by the temperature monitoring module to confirm the braking state. For example, a continuous rise in temperature after the brake is opened indicates a brake opening failure alarm.

[0051] In this embodiment, a YEZ electric hydraulic drum brake auxiliary mechanism is used, taking the use of the brake as an example;

[0052] When the high-pressure system of the belt conveyor fails and the brake cannot be opened, we start the hydraulic oil pump to start the hydraulic cylinder, and drive the support arm 2 to rise through the hydraulic cylinder to drive the brake rod 7 to open the brake. During the movement, the first paddle 5 synchronously stimulates the first limit switch 3 upward, prompting the rise to the position and stopping the movement. On the contrary, when closing the switch, the second paddle 6 stimulates the second limit switch 4 downward, prompting the fall to the position.

[0053] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
