Abstract

The utility model relates to the mining and construction industries and is aimed at improving the reliability of operation, the operational efficiency of the hydraulic hammer. The specified technical result is achieved in a hydraulic hammer containing a housing in which a percussion mechanism with pressure and drain channels is installed, interacting with the working tool for its reciprocating movements, moreover, a cavity with lubricant is made in the housing and a pump is connected to the cavity and supplying lubricant material from the cavity to the axle box for lubrication of the working tool installed in it in automatic mode.

Description

The utility model relates to auxiliary attachments for dismantling, when working with soils, in particular to hydraulic percussion mechanisms, and is intended to be used as replacement equipment for construction and road machines for the destruction of strong rocks, road surfaces, concrete structures and the like works.

A percussion hammer is known, including a lubricating device having a lubricant reservoir and a volume of lubricant contained therein. The lubricating device transmits the lubricant to at least one transmission system in the hammer body, impact system and / or tool holder at a variable dosage or flow rate. The dosage or flow rate varies depending on the voltage of the tool, which may include the intensity of use and / or temperature. A flexible tube extends between the reservoir and the lubricated component (s). Part of the flexible pipe vibrates with the lubricated components during use and changes the viscosity of the lubricant in it, based on the intensity of use of the tool. The pressure generating device can exert pressure on the lubricant, which helps to transport the lubricant to the target area for lubricating moving parts (US 8047302, 11/01/2011).

The disadvantage of this device is the complexity of the design and operation, as well as the unreliability of the supply of lubricant.

The technical problem to which the proposed utility model is directed is to expand the arsenal of technical means of hydraulic hammers, the parameters of which provide an increase in the operational characteristics of hydraulic hammers.

The technical result achieved by the implementation of this utility model is to increase the reliability and durability, the operational efficiency of the hydraulic hammer.

The specified technical result is achieved in a hydraulic hammer containing a housing in which a percussion mechanism with pressure and drain channels is installed, which interacts with the working tool for its reciprocating movements, while a cavity with a lubricant is made in the housing and a pump is configured to supply a lubricant material from the cavity to the axle box for lubrication of the working tool installed in it.

The pump is located inside the housing and is attached to the cavity with the lubricant and delivers the lubricant in the axle box in automatic mode.

The cavity with the lubricant is made vertical along the percussion mechanism.

The location of the lubricant in the cavity (compartment) of the housing, and not in a separate tank / cartridge, increases the volume of lubricant, which increases the durability and operating efficiency of the hydraulic hammer, and the location of the pump and cavity for lubrication inside the housing increases the reliability of the entire device. In addition, the execution of the cavity with the lubricant vertical along the percussion mechanism allows you to save the dimensions of the hammer using the internal space of the body of the hammer, as well as use a pump of lower power.

The essence of the utility model is illustrated by the drawing, which shows in cross section the claimed hydraulic hammer with a cavity with lubricants.

Accepted designations:

1. Hydrohammer body

2. Impact mechanism

3. Buchs

4. Lubricant cavity

5. Lubricant

6. The pump

7. Work tool

The hydraulic hammer comprises a housing 1, in which a percussion mechanism 2 with pressure and drain channels is installed. The shock mechanism 2 interacts with the working tool 7 for its reciprocating movement. The working tool 7 is placed in the housing 1 through the axle box 3.

A cavity 4 with a lubricant is made in the housing 1 and a pump 6 is installed, which supplies lubricant from the cavity 4 to the axle box 3 for lubricating the working tool 7 installed in it.

The cavity 4 with the lubricant has a volume of several tens of liters.

The pump 6 is located inside the housing 1 and is attached to the cavity 5 with lubricant, and the pump 6 delivers a certain amount of lubricant to the axle box 3 of the hydraulic hammer in automatic mode.

The device operates as follows - when the hydraulic hammer is turned on, pressure arises in the pressure channel, as a result of which the pump feeds a portion of the lubricant into the axle box to lubricate the working tool installed in it. When the hydraulic hammer is turned off, the pump draws another portion of the lubricant into itself from the cavity (reservoir). Serving size can be adjusted.
