The utility model relates to a constant stroke hydraulic counter-blow hammer and relates to a hydraulic counter-blow hammer. The constant stroke hydraulic counter-blow hammer comprises a counter-blow oil cylinder set (1), a lower hammerhead (2), an upper hammerhead (3), a hammer carrier (4), and a hydraulic power and control system (5). The upper hammerhead (3) and the lower hammerhead (2) are arranged in the hammer carrier (4) and are guided by the hammer carrier while moving, the counter-blow oil cylinder set (1) is arranged on a base of the hammer carrier (4), the hydraulic power and control system (5) is directly arranged on the hammer carrier (4), and a full hydraulic drive is adopted for the movement of the hammer. Problems of low energy utilization rate of a conventional compressed air or steam transmission counter-blow hammer and the insecurity during the production process of a conventional steel belt or steel wire rope linkage counter-blow hammer are solved by the constant stroke hydraulic counter-blow hammer; and the hydraulic power and hydraulic control system is directly arranged on the hammer carrier so that the length of an oil circuit is shortened and the response speed of the hydraulic system is increased.
Description
Technical field:
The utility model relates to a kind of hydraulic pressure counter-blow hammer, is specifically related to a kind of stroke hydraulic counter-blow hammer that waits.
Background technology:
Traditional counter-blow hammer power adopts compressed air or steam, because compressed air or steam pipeline road are longer, exist in a large number and leaks, and energy utilization rate is very low, has large quantity of exhaust gas or waste water to discharge simultaneously in the course of work, and environment is polluted; The lower ram interlock adopts steel band or steel wire rope to realize interlock on the traditional counter-blow hammer in addition, and this structural device physical dimension is bigger, and steel band or rope service-life are shorter simultaneously, in case steel band occurs or security incident can take place wire cable rupture.
The utility model content:
The purpose of this utility model provides a kind of stroke hydraulic counter-blow hammer that waits, it can solve conventional compression air or the low problem of steam transmission counter-blow hammer energy utilization rate, can solve simultaneously unsafe problem in traditional steel band or the steel wire rope interlock counter-blow hammer production process again, hydraulic power and hydraulic control system are directly installed on the hammer carrier, such structural configuration has shortened the length of oil circuit, has improved the response speed of hydraulic system.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it is by to hitting oil cylinder group 1, lower ram 2, upper ram 3, hammer carrier 4, hydraulic power and control system 5 are formed, upper ram 3 and lower ram 2 are installed in the hammer carrier 4, lead by hammer carrier during motion, be installed on hammer carrier 4 bases hitting oil cylinder group 1, hydraulic power and control system 5 are directly installed on the hammer carrier 4, such structural configuration has shortened the length of oil circuit, reduced the pressure loss of pipeline, improve the response speed of hydraulic system, by hammer carrier each several part has been connected into one.
Described lower ram 2 and upper ram 3 adopt realizes interlock to hitting oil cylinder group 1, and the quality of lower ram 2, upper ram 3 equates that its movement velocity equates that movement travel equates.
Described upper ram 3 adopts all-hydraulic power drive to realize moving up and down, the upper and lower cavity that so-called all-hydraulic power drive refers to drive the oil cylinder of tup motion all adopts hydraulic oil, the generation that such system has avoided gas leakage and liquid, gas to scurry mutually, hitting motion is the principle that adopts differential cylinder, the oil cylinder upper and lower cavity all advances hydraulic oil when namely hitting motion, the epicoele oil extraction that communicates with fuel tank during backhaul.
Adopt between described upper and lower tup to hit that the oil cylinder group realizes moving synchronously, to the area that hits two small oil tanks about the oil cylinder group and the area that equals oil cylinder broad in the middle, that has realized upper and lower tup like this waits stroke and movement at the uniform velocity.
The utility model can solve conventional compression air or the low problem of steam transmission counter-blow hammer energy utilization rate, can solve simultaneously unsafe problem in traditional steel band or the steel wire rope interlock counter-blow hammer production process again, hydraulic power and hydraulic control system are directly installed on the hammer carrier, such structural configuration has shortened the length of oil circuit, has improved the response speed of hydraulic system.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment adopts following technical scheme: it is by forming hitting oil cylinder group 1, lower ram 2, upper ram 3, hammer carrier 4, hydraulic power and control system 5, upper ram 3 and lower ram 2 are installed in the hammer carrier 4, lead by hammer carrier during motion, be installed on hammer carrier 4 bases hitting oil cylinder group 1, hydraulic power and control system 5 are directly installed on the hammer carrier 4, such structural configuration has shortened the length of oil circuit, reduced the pressure loss of pipeline, improve the response speed of hydraulic system, by hammer carrier each several part has been connected into one.
The operation principle of described hydraulic power and control system 5 is: as valve one Y1, valve two Y2 get when electric, on the driving oil cylinder, cavity of resorption all advances hydraulic oil, move downward by differential driving upper ram 3, can realize that by being designed to equal left and right sides small plunger rod area sum to the sectional area that hits oil cylinder group plunger rod broad in the middle the plunger rod broad in the middle stroke that moves upward moves downward stroke with two pillar stopper rods and equates, therefore lower ram 2 is in that realizations waits stroke to move upward realization to hitting under 1 effect of oil cylinder group to hitting, when valve one Y1 dead electricity, drive hydraulic oil process valve one Y1 and valve four Y4 oil sump tanks in the oil cylinder epicoele, realize that under driving oil cylinder cavity of resorption hydraulic oil and lower ram deadweight effect upper ram moves upward, lower ram moves downward backhaul; Valve three Y3 and valve four Y4 get when electric, by throttle orifice realize upper ram slowly down and lower ram go up slowly.
Described lower ram 2 and upper ram 3 adopt realizes interlock to hitting oil cylinder group 1, and the quality of lower ram 2, upper ram 3 equates that its movement velocity equates that movement travel equates.
Described upper ram 3 adopts all-hydraulic power drive to realize moving up and down, the upper and lower cavity that so-called all-hydraulic power drive refers to drive the oil cylinder of tup motion all adopts hydraulic oil, the generation that such system has avoided gas leakage and liquid, gas to scurry mutually, hitting motion is the principle that adopts differential cylinder, the oil cylinder upper and lower cavity all advances hydraulic oil when namely hitting motion, the epicoele oil extraction that communicates with fuel tank during backhaul.
Adopt between described upper and lower tup to hit that the oil cylinder group realizes moving synchronously, to the area that hits two small oil tanks about the oil cylinder group and the area that equals oil cylinder broad in the middle, that has realized upper and lower tup like this waits stroke and movement at the uniform velocity.
This specific embodiment can solve conventional compression air or the low problem of steam transmission counter-blow hammer energy utilization rate, can solve simultaneously unsafe problem in traditional steel band or the steel wire rope interlock counter-blow hammer production process again, hydraulic power and hydraulic control system are directly installed on the hammer carrier, such structural configuration has shortened the length of oil circuit, has improved the response speed of hydraulic system.
