Description
Technical field:
The utility model relates to a kind of break, is the break that is used on crane gear and the transmission device specifically.
Background technique:
Traditional break be electromagnetic type and hydraulic type as power source, the two is limited by ambient temperature all, electromagnetic type is cisco unity malfunction under the big environment of dust, easily makes coil burnout; The shortcoming of hydraulic type is that hydraulic electric motor easily burns, hydraulic cylinder easy oil leakage, slow movement.
Summary of the invention:
It is power source that the purpose of this utility model provides a kind of employing pressurized gas, the atmospheric brake that brake shoe is opened or lock.
Above-mentioned purpose realizes by following technological scheme:
Atmospheric brake, its composition comprises: brake bracket, be installed in the regulating lever on the described brake bracket, nut, push pedal, main spring and adjustment nut are arranged on the described regulating lever, be fixed with brake shoe above the described brake bracket, the fixed plate of described brake bracket upper end is provided with air-operated apparatus, on the described pneumatic wall suction port and air outlet is arranged, described air-operated apparatus inner chamber has piston, and the piston rod of described piston is coaxial with described regulating lever.
This technological scheme has following beneficial effect:
1. the utility model is to utilize air valve to make Brake drum braking or operation as power by brake shoe, has avoided adopting electromagnetism and hydraulic pressure as power source in the past, and coil and controller easily burn, and influence the phenomenon of winch proper functioning.
2. because the utility model is by the air-operated apparatus air inlet, drive piston, regulating lever motion, nut, main spring produce relative movement and make brake shoe brake and leave, and the braking effect of Chan Shenging is reliable like this.
The utility model simple in structure, be active in one's movements, brake and reliable, working life compare with the traditional braking device and can be higher than 3-5 doubly, be not subjected to environmetal impacts such as temperature and dust, easy to maintenance, characteristics such as energy-efficient.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
Embodiment of the present utility model:
Embodiment 1:
Atmospheric brake, its composition comprises: brake bracket 1, be installed in the regulating lever 13 on the described brake bracket 1, on the described regulating lever 13 nut 8 is arranged, push pedal 9, main spring 7 and adjustment nut 11, adjust the distance that nut 11 is used for adjusting piston rod 6 and regulating lever 13, nut 8 is used to adjust the length of main spring 7, change the braking moment of brake shoe 2, be fixed with brake shoe 2 above the described brake bracket 1, the fixed plate of described brake bracket 1 upper end is provided with air-operated apparatus 3, on described air-operated apparatus 3 walls suction port 4 and air outlet 14 are arranged, described air-operated apparatus 3 inner chambers have piston 5, and described piston 5 is connected with piston rod 6.
Above-mentioned atmospheric brake, its working principle is: when bridge motor energising work, need brake shoe 2 to open, suction port 4 is opened in the solenoid valve energising, and at this moment the piston 5 of air-operated apparatus 3 inner chambers moves right under the effect of air pressure, promotes piston rod 6 and moves right, piston rod 6 promotes regulating lever 13 and moves right, right side brake bracket 1 moves right, and makes brake shoe 2 leave Brake drum 10, and Brake drum 10 is moved.When stopping, the solenoid valve outage is closed, and suction port 32 is closed thereupon, has not had air pressure in the air-operated apparatus 3, and piston 5 is subjected to the effect of main spring 7 elastic force to left movement, and right side brake bracket 1 is moved to the left, and makes brake shoe 2 compress Brake drum 10, and winch is out of service.
Above-mentioned atmospheric brake, install and adjust:
(1). this machine is under braking state, and brake shoe 2 intrados must be close on the Brake drum.When air-operated apparatus 3 runs to the summit, adjust bolt 11, make the intrados of two brake shoe 2 and moving back of 10 of Brake drums apart from equating.
(2). the initial stroke of air-operated apparatus 3 should be transferred to the brake shoe that is slightly less than the rated travel correspondence and move back distance, when the brake shoe liner weares and teares gradually, when the stroke of air-operated apparatus moves closer to maximum value, stroke should be adjusted back to initial stroke, guaranteeing the break proper functioning, otherwise cause braking moment to reduce and brake ineffective.
Claims (1)
1. atmospheric brake, its composition comprises: brake bracket, be installed in the regulating lever on the described brake bracket, nut, push pedal, main spring and adjustment nut are arranged on the described regulating lever, be fixed with brake shoe above the described brake bracket, it is characterized in that: the fixed plate of described brake bracket upper end is provided with air-operated apparatus, on the described pneumatic wall suction port and air outlet is arranged, described air-operated apparatus inner chamber has piston, and the piston rod of described piston is coaxial with described regulating lever.
