Problems solved by technology

[0003] For the emergency and parking brake device of the existing design, after starting the diesel engine, when the compressed air in the compressed air tank does not reach the minimum working pressure of 0.4MPa, the button switch cannot be pressed down, and the emergency and parking brake control valve cannot be opened. , the brake is in the braking state, causing the loader to fail to start, and it needs to wait until the air pressure reaches the normal range before it can be used
The user cannot intuitively see the air pressure of the compressed air tank, and the waiting time becomes longer, wasting time and energy

Embodiment Construction

[0013] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0014] Such as figure 1 As shown, an emergency and parking brake device for a loader includes a compressed air tank 1, an emergency and parking brake control valve 3 and a brake 9. The brake 9 has the function of decelerating, stopping or maintaining the moving parts (or moving machinery) Devices with functions such as stop status, commonly known as brakes and brakes.

[0015] The compressed air tank 1 is provided with a pressure gauge 2, and the pressure gauge 2 transmits the pressure deformation through the elastic deformation of the sensitive elements (Bourdon tube, diaphragm box, bellows) in the gauge, and then the conversion mechanism of the ...

Abstract

The invention discloses an emergency and parking braking device of a loader. The emergency and parking braking device of the loader comprises a compressed air tank, an emergency and parking braking control valve and a brake, and is characterized in that the compressed air tank is provided with a pressure gage and is connected with one end of the emergency and parking braking control valve; the emergency and parking braking control valve is provided with a button switch for controlling the emergency and parking braking control valve to be connected or disconnected; the other end of the emergency and parking braking control valve is connected with a quick release valve; the quick release valve is connected with a variable speed control cut-off valve and a brake chamber respectively; the bottom of the brake chamber is provided with a vertical ejector rod; the tail end of the ejector rod is horizontally provided with a pull rod; the tail end of the pull rod is connected with the brake. Users can conveniently and rapidly start the emergency and parking braking device, and the emergency and parking braking device of the loader has the indication function and is simple in structure and high in efficiency.

Description

technical field [0001] The invention relates to an emergency and parking brake device for a loader. Background technique [0002] The emergency and parking brake device is used to brake the loader when there is an emergency during work, and to play a safety protection role when the brake system air pressure is too low, mainly used for parking. [0003] For the emergency and parking brake device of the existing design, after starting the diesel engine, when the compressed air in the compressed air tank does not reach the minimum working pressure of 0.4MPa, the button switch cannot be pressed down, and the emergency and parking brake control valve cannot be opened. , the brake is in the braking state, causing the loader to fail to start, and it needs to wait until the air pressure reaches the normal range before it can be used. The user cannot intuitively see the air pressure of the compressed air tank, and the waiting time becomes longer, wasting time and energy. Contents ...
