Description

A cooling device for a hydraulic breaker

technical field

The utility model relates to a breaking hammer, in particular to a cooling device for a hydraulic breaking hammer.

Background technique

With the rapid development of my country's economy, infrastructure construction has entered an accelerated period. Breaking hammers are widely used in the process of project implementation. It can greatly improve work efficiency and save manpower, material and financial resources. Therefore, the breaking hammer has attracted extensive attention in our country, but from the perspective of the current manufacturing level in our country, the development of the breaking hammer industry is not ideal. The overall performance is that there is a large demand, but the country cannot meet self-sufficiency, and mainly relies on imports from foreign countries. However, whether it is a domestic brand or a foreign brand we are using now, they all have excessive noise, high temperature of the breaker and cylinder block. If these problems are not solved, it will inevitably affect the production and life and the development of the breaking hammer industry. After extensive searching, no ideal technical solution has been found yet.

Utility model content

The purpose of this utility model is to propose a cooling device for a hydraulic breaker in order to solve the shortcomings of the breaker at the present stage, such as high temperature, cylinder cavitation, and high noise.

In order to achieve the above object, the utility model adopts the following technical solutions:

A cooling device for a hydraulic breaker, comprising a cylinder, a piston rod is movably connected to the inside of the cylinder, a drill rod is connected to the front end of the piston rod, and the cylinder is connected to the hydraulic pressure through a set of oil pipes. The system is characterized in that: a group of connected pipes are arranged in the cylinder, and the water inlet and water outlet of the pipe are respectively arranged on both sides of the cylinder, and the water inlet and the water outlet are connected by water pipes. A water pump and a water tank are respectively arranged on the water pipe.

On the basis of above-mentioned technical scheme, can have following further technical scheme:

A multi-pipe cooler is also connected to the water pipe.

The oil pipes of the cylinder are all arranged in the corresponding pipelines.

The pipe is wrapped around the cavity of the cylinder.

During operation, the water pump is used to pump water out of the water tank. After the water is cooled by the multi-tube cooler, it is passed into the cylinder to cool the piston rod and drill rod. Since the oil pipes of the cylinder are all arranged in the pipeline, at the same time The oil pipe is also cooled to effectively reduce the temperature of the breaker, thereby reducing the occurrence of cavitation and prolonging the life of the breaker.

The utility model has the advantages that: the device has small changes to the structure of the existing breaker, simple structure, low cost, reduces cavitation and noise when the breaker is working, improves the working life of the breaker and plays an important role in the breaker body. protective effect.
