Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Please refer to figure 2 , the embodiment of the present invention provides a brake device 5 applied to a slide in large engineering equipment (not shown).

[0022] The engineering equipment includes an aerial ladder 3, a turntable 9 and an oil cylinder 8. Wherein, the aerial ladder 3 is rotatably installed on the turntable 9, and the oil cylinder 8 is connected to the aerial ladder 3 and the turntable 9, and the amplitude of the aerial ladder 3 is changed by extending the oil cylinder 8 to carry out high-altitude rescue.

[0023] The cloud ladder 3 comprises a ladder frame 10, a guide rail 4, a slide bucket 7, a slide bucket driving device and a brake device 5 of the slide bucket. The ladder frame 10 is connected to the oil cylinder 8 and the turntable 9 . The guide rail 4 is fixedly installed on the aerial ladder 3, and the slide bucket 7...

Abstract

The invention discloses a brake device of a skid hopper and an aerial ladder using the brake device of the skid hopper. The skid hopper is arranged on a guide rail and runs along the guide rail under the drive of a skid hopper driving device. The brake device comprises a rotating shaft, a brake wheel, a connecting plate, a first traction mechanism and a second traction mechanism, wherein the rotating shaft is rotatably installed on the skid hopper, the brake wheel and the connecting plate are fixedly installed on the rotating shaft are can rotate with the rotating shaft, the first end of the first traction mechanism is fixedly arranged on the connecting plate, the second end of the first traction mechanism is fixedly arranged on the skid hopper, the first end of the second traction mechanism is fixedly connected onto the connecting plate, and the second end of the second traction mechanism is connected with the skid hopper driving device, so that when the second end of the second traction mechanism is separated from the skid hopper driving device, the first traction mechanism drives the rotating shaft to rotate around a first direction and enable the brake wheel to be in contact with the guide rail to realize braking. The brake device of the skid hopper has the advantages of simple braking realizing structure and easiness in realization.

Description

technical field [0001] The invention relates to a braking device applied to a sliding bucket in large-scale engineering equipment and an aerial ladder using the braking device of the sliding bucket. Background technique [0002] The ladder truck is a kind of fire truck, which is equipped with a retractable ladder for firefighters to extinguish fires and rescue trapped people. Further, a slide device can be installed on the ladder to improve the rescue capability. Among them, the brake device is an important part of the slide bucket device, which can realize emergency braking of the slide bucket when an unexpected situation occurs. [0003] Please refer to figure 1 , an elevator upward protection device pushes one end of the cam body through a power spring to generate a rotational moment, and then uses the cam surface to press the brake plate to achieve braking. When an accident occurs in the elevator, the force signal input from the outside acts on the trigger lever 1, pu...
