Embodiment Construction

[0012] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0013] Also refer to figure 1 and figure 2 , a loader auxiliary parking device with a load as the power source, comprising a frame working machine body 1, a hydraulic cylinder 2, a parking brake 3 and a transmission shaft 4, and the parking brake 3 is equipped with a brake caliper The piston 5 and the brake caliper brake piston 5 are connected through an oil pipe 7 equipped with a solenoid valve 6 , and the other end of the oil pipe 7 is connected to the oil port 8 at the bottom of the hydraulic cylinder 2 . The hydraulic cylinder 2 and the brake caliper brake piston 5 are connected to each other through the oil pipe 7. When the loading hopper 9 carries heavy materials, it will generate a downward pressure on the hydraulic cylinder 2. The hydraulic oil in the hydraulic cylinder 2 must have Enough pressure can support the loading hopper 9. When braking ...

Abstract

The invention provides a loader auxiliary parking device using the load as the power source. The loader auxiliary parking device comprises a carframe working machine body, a hydraulic cylinder and a parking brake, wherein a brake caliper braking piston is configured on the parking brake; a charging hopper is arranged at the front part of the carframe working machine body; the hydraulic cylinder is supported on the charging hopper; and an oil pipe is connected between the hydraulic cylinder and the brake caliper braking piston; and an electromagnetic valve is installed on the oil pipe. When the loader is loaded, the brake caliper braking piston is pushed by the pressure of the hydraulic cylinder, so that a transmission shaft stops driving and then the brake action is achieved. The loader auxiliary parking device has the advantages that when the loader is largely loaded, the safe, reliable, rapid and balance parking brake can be realized.

Description

technical field [0001] The invention relates to a parking device, more specifically a loader parking device with a load as a power source. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in road, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand, lime, coal, etc. , hard soil, etc. for light shoveling and digging operations. When the loader is working, it often needs to perform frequent reciprocating movements, which makes the use of its braking system extremely frequent. Therefore, the reliability, controllability, and stability of the braking performance of the loader have been raised more and more. The high requirements and the quality of its braking have a great impact on the working efficiency of the whole machine, and it is also related to the major issues of personnel and machine safety. [0003] At present, most domestic loade...
