Description

Loader brake piston

Technical Field

The utility model relates to a stopper piston technical field specifically is a loader stopper piston.

Background

A brake is a device having a function of decelerating, stopping, or holding a stopped state of a moving member or a moving machine. Is a mechanical part that stops or decelerates moving parts in a machine. Commonly called brake and brake. The brake mainly comprises a braking frame, a braking piece, an operating device and the like. Some brakes are also equipped with automatic adjustment of the brake clearance. In order to reduce the braking torque and the structural size, the brake is usually mounted on the high-speed shaft of the equipment, but large equipment with high requirements on safety, such as a mine hoist, an elevator and the like, is mounted on the low-speed shaft close to the working part of the equipment, and the piston is an internal component for generating braking by the brake.

The existing brake piston on the market does not have an anti-corrosion function and is not high-temperature resistant, so that the brake piston is easy to rust, the temperature is too high in a continuous working state, and the service life of the brake piston is influenced.

In order to solve the problems, innovative design is urgently needed on the basis of the original brake piston, and therefore a loader brake piston is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a loader stopper piston to the stopper piston that proposes in solving above-mentioned background art does not possess the anticorrosion function and can not resist high temperature, thereby leads to the stopper piston easily to go up the rust and too high temperature under lasting operating condition, influences stopper piston life's problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a loader stopper piston, includes shell and inner bag, the top welding of shell has the layer of borduring, and the inside of shell is provided with first recess, the below of first recess is provided with the kerve, the top welding of inner bag has the plating coat, and the inner bag is located the inside of first recess, the inside of inner bag is provided with the second recess.

Preferably, be welded connection between layer of borduring and the shell, and the bottom on layer of borduring closely laminates with the top of shell.

Preferably, the inner container and the shell form a fixed structure through the first groove, and the center line of the inner container and the center line of the shell are overlapped.

Preferably, the electroplating surface and the inner container are connected in a welding manner and are parallel to each other.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the loader brake piston is provided with the shell, and the shell arranged outside the inner container enables the brake piston to improve heat resistance, flame retardance and corrosion resistance, so that the phenomenon that the brake piston is burnt and damaged due to overhigh temperature when the brake piston runs at high speed for a long time is avoided.

FIG. 2 is a schematic side view of the present invention;

fig. 3 is a schematic view of the top view structure of the present invention.

In the figure: 1. a housing; 2. a binding layer; 3. a first groove; 4. a bottom groove; 5. an inner container; 6. electroplating the surface; 7. a second groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a loader brake piston comprises a shell 1 and a liner 10, wherein a binding layer 2 is welded above the shell 1, a first groove 3 is formed in the shell 1, the binding layer 2 is welded with the shell 1, and the bottom of the binding layer 2 is tightly attached to the top of the shell 1, the design is that the binding layer 2 can seal the liner 5 without a gap, the flame retardance of the piston is improved, air is placed into the first groove 3, a bottom groove 4 is formed below the first groove 3, an electroplating surface 6 is welded above the liner 5, the liner 5 is located in the first groove 3, the liner 5 and the shell 1 form a fixed structure through the first groove 3, the central line of the liner 5 is overlapped with the central line of the shell 1, the design is used for improving the heat resistance and power insulation of the piston through the shell 1 and prolonging the service life of the piston, for welded connection between plating face 6 and the inner bag 5, and be parallel to each other between plating face 6 and the inner bag 5, such design is in order to conveniently change the rubber ring through 6 installation rubber rings of plating face, and the inside of inner bag 5 is provided with second recess 7.

The working principle is as follows: the loader brake piston has the use flow that firstly the quality of the brake piston can be improved through the shell 1, the cover shell 1 is made of BMC (bulk molding compound) material and is formed by mixing and processing various main and auxiliary materials such as polyester resin, glass fiber, filler, pigment, auxiliary agent and the like through a specific process, the housing 1 has excellent electrical insulation performance, higher mechanical performance, good heat resistance, flame retardance, corrosion resistance and the like, reduces damage to the brake piston, prolongs the service life of the brake piston, and further, can seal the gap between inner bag 5 and the first recess 3 through layer 2 of borduring, avoid the stopper piston to get into the gap production spark at the during operation air, can also install the rubber ring through the electroplating surface 6 of inner bag 5 top, 6 difficult upper rusts of electroplating surface reduce the purchase cost of stopper piston, and second recess 7 is for piston and stopper cooperation production atmospheric pressure propulsion braking.
