[0027] Embodiment 1

[0028] Reference Figure 1 - Figure 5: An electric roller brake check device, comprising: a workbench 1, a drive fine-tuning component, which is arranged at the top of the outer wall of the workbench 1, wherein: a drive fine-tuning component support column 2, a mounting sleeve 3, an electric hydraulic pusher 4, a rotating arm 5, a fixed platform 6, a moving column 7, a first slide rail 601, a second slide rail 602 and a fine-tuning bolt 13, the support column 2 and the fixed platform 6 are respectively fixedly arranged at both sides of the top of the outer wall of the workbench 1, the first slide rail 601 and the second slide rail 602 are fixedly arranged on the outer wall of the fixed platform 6, the moving column 7 is slidably sleeved at the top of the outer wall of the first slide rail 601, a protrusion on one side of the outer wall of the moving column 7 matches the second slide rail 602, the fine-tuning bolt 13 is rotatably embedded in the inner wall of the fixed platform 6, and the fine-tuning bolt One end of 13 is threadedly connected to the inner wall opening of the moving column 7, the rotating arm 5 is rotatably plugged into the outer wall of the output end of the electric hydraulic pusher 4, the inner wall of the rotating arm 5 is fixedly provided with a driving shaft 18, and one end of the driving shaft 18 is rotatably embedded in the inner wall opening of the moving column 7, the mounting sleeve 3 is rotatably sleeved on the top outer wall of the support column 2 through a latch, the electric hydraulic pusher 4 is rotatably sleeved on the outer wall of the mounting sleeve 3 through a latch, and the brake assembly is arranged at the top of the outer wall of the workbench 1, wherein: the brake assembly includes a moving ring 14, a brake pad 15, a cooling pipe 16, a support spring 17 and a friction ring 1001, the moving ring 14 is slidably embedded in the inner wall opening of the rotating arm 5, the brake pad 15 is fixedly arranged on the outer wall of the moving ring 14, and the cooling pipe 16 is provided. The cooling tube 16 is embedded in the groove of the inner wall of the moving ring 14, one end of the support spring 17 is fixedly set on the inner wall of the rotating arm 5, and the other end of the support spring 17 is fixedly set on the outer wall of one end of the moving ring 14. The friction ring 1001 and the brake pad 15 match each other. First, the electric drum is installed inside the constraint cylinder 10, and then the fixation is completed. The fine-tuning bolt 13 is rotated to make the moving column 7 move on the first slide rail 601 and the second slide rail 602, and the distance between the rotating arm 5 and the friction ring 1001 is fine-tuned to ensure that when the electric hydraulic pusher 4 is started, the brake pad 15 is completely in contact with the outer wall of the friction ring 1001. When the electric drum fails and cannot be stopped in time, the electric hydraulic pusher 4 is started to make the rotating plate produce Deflection, then the moving ring 14, under the action of the supporting spring 17, drives the brake pad 15 to contact the friction ring 1001 to complete the braking function. At this time, a large amount of heat is generated and accumulated in the inside of the brake pad 15 and the friction ring 1001. At this time, the vortex fan 12 is exhausted, and a large amount of cooling airflow enters the inside of the semi-sealed shell 11. The heat exchange function of the airflow is used to complete the cooling. At this time, the external coolant supply recovery device supplies the coolant to the inside of the cooling pipe 16 to complete the second cooling, ensuring that the brake pad 15 will not fail due to heat when contacting the friction ring 1001, resulting in a decrease in the braking effect. When debris splashes, the semi-sealed shell 11 can restrain the debris to avoid injuries to the staff caused by debris splashing.

A semi-sealed shell 11 is fixedly provided on the outer wall of the support frame 8 through a bracket. An opening is opened on one side of the outer wall of the semi-sealed shell 11. The semi-sealed shell 11 is matched with the rotating arm 5 through the opening. The cooling pipe 16 is connected to the valve through a pipeline and is arranged in an external cooling water supply and recovery device, which can ensure the stable supply and recovery of the coolant. A vortex fan 12 is arranged on one side of the outer wall of the semi-sealed shell 11 through a pipeline.

[0030] Reference Figure 1 - Figure 5 : The restraining cylinder 10 matches the external electric drum, and the outer wall of the brake pad 15 is provided with a heat dissipation groove to ensure the stability of airflow cooling. The cross section of one side of the outer wall of the rotating arm 5 is in an arc shape.

[0031] Working principle:

[0032] First, install the electric drum to the inside of the constraint cylinder 10, then fix it, rotate the fine-tuning bolt 13, so that the moving column 7 moves on the first slide rail 601 and the second slide rail 602, and fine-tune the distance between the rotating arm 5 and the friction ring 1001 to ensure that when the electric hydraulic pusher 4 is started, the brake pad 15 is in full contact with the outer wall of the friction ring 1001. When the electric drum fails and cannot be stopped in time, start the electric hydraulic pusher 4 to deflect the rotating plate, and then the moving ring 14 drives the brake pad 15 to contact the friction ring 1001 under the action of the supporting spring 17. , completing the braking function, at this time a large amount of heat is generated and accumulated in the inside of the brake pad 15 and the friction ring 1001, at this time the vortex fan 12 is exhausted, a large amount of cooling airflow enters the inside of the semi-sealed shell 11, and the heat exchange function of the airflow is used to complete the cooling, and at this time the external coolant supply recovery device supplies the coolant to the inside of the cooling pipe 16 to complete the second cooling, ensuring that the brake pad 15 contacts the friction ring 1001 without failure due to heat, resulting in a decrease in the braking effect, and when debris splashing, the semi-sealed shell 11 can restrain the debris to avoid injuries to the staff caused by debris splashing.
