Abstract
A pressure stabilizer for hydraulic breaker which is used as the pressure stabilizing design for breaking reciprocating elements in mining. The device is composed of a hydraulic control component which is attached on the breaker cylinder body. The device is characterized in that this is a pilot two-position three-way solenoid value which is communicated with the oil source under pressure and breaker cylinder body respectively. The pilot two-position three-way solenoid valve is separately arranged outside the breaker cylinder body. Since an external structure is used by the utility model for oil flow and the pressure stabilizer, easy equipment disassembling and maintenance is then allowed for the equipment. Moreover, oil pressure in the pipeline is stabilized and lifetime cycle of the pipeline is increased. In addition, since all the components used are commercially available and no special coupling techniques are required for product assembly, the market potential for this product is tremendously high.
Description
Technical field
The utility model belongs to the voltage stabilizing mechanism of mining with the reciprocal element fragmentation, specifically is a kind of hydraulic breaking hammer stable-pressure device.
Background technology
After hydraulic breaking hammer is mainly used in the mine underground blasting, the ore that surpasses the ore removal lumpiness is carried out second-time breakage to be handled, can work reliably in order to make hydraulic breaking hammer, just need make the constant pressure in the hydraulic breaking hammer, for this reason, prior art products just is provided with the distribution and the constant pressure device of hydraulic oil in the cylinder body of hydraulic breaking hammer, because of hydraulic breaking hammer mainly is to use under mine, be subjected to the influence of abominable working environment under the mine, need frequent distribution and constant pressure device to overhaul to hydraulic oil, safeguard, therefore, the distribution of built-in hydraulic oil and constant pressure device extremely are difficult to dismounting when safeguarding, increase the difficulty of plant maintenance greatly, thereby reduced maintainer's operating efficiency, had influence on the normal use of equipment.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of and is convenient to equipment dismounting, maintenance, and can stablize line pressure, prolongs the hydraulic line hydraulic breaking hammer stable-pressure device in application life.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is a kind of hydraulic breaking hammer stable-pressure device, comprise Hydraulic Conirol Unit with hydraulic breaking hammer cylinder body coupling, it is characterized in that described Hydraulic Conirol Unit two three-way solenoid valves of guide for linking with pressure oil-source and hydraulic breaking hammer cylinder body respectively, two three-way solenoid valves of guide independently are arranged on the outside of hydraulic breaking hammer cylinder body.
For the pressure in the further constant pipeline,, between two three-way solenoid valves of guide and pressure oil-source, also be provided with diaphragm accumulator so that when two three-way solenoid valve internal pressures of guide are not enough, in time it is replenished for this reason.
After the utility model carries out above-mentioned improvement to prior art products, because distribution and constant pressure device to hydraulic oil have adopted outlet structure, and installed diaphragm accumulator additional, therefore have the equipment of being convenient to dismounting, safeguard, and can stablize line pressure, prolong the hydraulic line advantage in application life, in addition, two each parts such as three-way solenoid valve of guide that adopt because of the utility model are ripe prior art products, and adopt conventional connection technique that prior art products has been carried out the optimum organization of layout, apply so also be beneficial on a large scale.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model embodiment mounting structure schematic diagram.
Among the figure: 1 hydraulic breaking hammer cylinder body; 2 pipelines; 3 Hydraulic Conirol Units; 4 diaphragm accumulators.
The specific embodiment
As shown in Figure 1, this hydraulic breaking hammer stable-pressure device, comprise Hydraulic Conirol Unit 3 with hydraulic breaking hammer cylinder body 1 coupling, it is characterized in that described Hydraulic Conirol Unit 3 two three-way solenoid valves of guide for linking with pressure oil-source and hydraulic breaking hammer cylinder body 1 respectively, two three-way solenoid valves of guide independently are arranged on the outside of hydraulic breaking hammer cylinder body 1.
Pressure in the further constant pipeline 2 so that in time it is replenished, also is provided with diaphragm accumulator 4 for this reason between two three-way solenoid valves of guide and pressure oil-source when two three-way solenoid valve internal pressures of guide are not enough.
After the utility model carries out above-mentioned improvement to prior art products, because distribution and constant pressure device to hydraulic oil have adopted outlet structure, and installed diaphragm accumulator 4 additional, therefore have the equipment of being convenient to dismounting, safeguard, and can stablize pipeline 2 pressure, prolong the hydraulic line advantage in 2 application lifes, in addition, two each parts such as three-way solenoid valve of guide that adopt because of the utility model are ripe prior art products, and adopt conventional connection technique that prior art products has been carried out the optimum organization of layout, apply so also be beneficial on a large scale.
Claims (2)
