Abstract

The utility model concerns the mining and construction industry and aims to increase the efficiency of production and operation of a hydraulic hammer. The desired technical result is achieved in a hydraulic hammer which comprises a body in which is mounted an impact mechanism with supply and discharge channels interacting with the working instrument to ensure its movement back and forth; the body has a cavity with a lubricant and includes a pump connected to the cavity and feeding a lubricant from the cavity to the lubricating box to lubricate the working instrument therein in automatic mode.

Description

 Hydraulic hammer

 The utility model relates to ancillary attachments during dismantling works, when working with soils, in particular to hydraulic shock mechanisms, and is intended for use as replacement equipment for construction road machines for the destruction of durable rocks, pavements, concrete structures and the like. works

 Known shock hammer, which includes a lubricating device having a reservoir for lubrication and the volume of lubricant contained therein. The lubricator transmits lubricant to at least one transmission system in the hammer body, a percussion system and / or a tool holder with a variable dosing or flow rate. The dosing rate or flow rate varies depending on the instrument voltage, which may include usage intensity and / or temperature. A flexible tube passes between the reservoir and the component (s) to be lubricated. Part of the flexible tube vibrates with lubricated components during use and changes the viscosity of the lubricant in it, based on the intensity of use of the tool. A pressure device can exert pressure on the lubricant, which helps to transport the lubricant to the target zone for lubrication of 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 aimed at is the expansion of the arsenal of hydraulic hammers technical equipment, the parameters of which provide an increase in the operational characteristics of the hydraulic hammers.

 The technical result achieved in the implementation of this utility model is to improve the reliability and durability of the work, the efficiency of operation of the hydraulic hammer.

This technical result is achieved in a hydraulic hammer, comprising a housing in which a percussion mechanism with a pressure and drain channels is installed, which interacts with a working tool for reciprocating it, while a cavity with a lubricant and a pump is installed, configured to supply lubricant from the cavity to the bush for lubricating the working tool installed in it.

 The pump is located inside the housing and is attached to the cavity with a lubricant and delivers the lubricant to the axle box automatically.

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

 The location of the lubricant in the cavity (compartment) of the housing, and not in a separate tank / cartridge, contributes to an increase in the lubricant volume, which increases the durability of the hammer and the operation of the hydraulic hammer, and the location of the pump and the lubrication cavity inside the housing increases the reliability of the entire device. In addition, the implementation of the cavity with the lubricant vertical along the percussion mechanism allows you to keep the dimensions of the hammer using the internal space of the hammer, as well as apply a pump of lower power.

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

The hydraulic hammer comprises a housing 1, in which a percussion mechanism 2 with pressure and drain channels is installed. Impact mechanism 2 interacts with the working tool 7 for its reciprocating movement. Work tool 7 is placed in the housing 1 through the bush 3. In the housing 1 there is a cavity 4 with a lubricant and a pump 6 is installed, which supplies lubricant from the cavity 4 to the axle box 3 to lubricate the working tool 7 installed in it.

 Cavity 4 with a lubricant has a volume of several tens of liters.

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

 The device works as follows - when the hydraulic hammer is turned on in the pressure channel, pressure arises, as a result of which the pump delivers a portion of lubricant to the bush for lubrication of the working tool installed in it. When the hammer is turned off, the pump sucks in itself from the cavity (tank) another batch of lubricant. Portion volume can be adjusted.
