Abstract
A hydraulic hammer includes: pick poker bar, pick tube and pick handle; the hydraulic hammer has own power device, the power output through a clutch drives a reducing mechanism, which is connected with a power conversion mechanism, which converts rotary movement output from the reducing mechanism to move up and down along the axial direction of the pick poker bar and drive the piston through the hydraulic oil to transmit the movement to the pick poker bar. The hammer head impacts the pick poker bar through the hydraulic oil in the process of work, reverse acting force is passed to the hydraulic oil and is absorbed by the hydraulic oil, so that the hydraulic hammer vibrates slightly and the machine and tool are protected. As the hydraulic hammer has an own power device, the hydraulic hammer is only taken in the field or poor environmental conditions, simplifying the machinery and equipment required for the field operations greatly.
Description
Technical field:
The utility model relates to a kind of hand-held engineering machinery instrument, particularly a kind of hydraulic hammer.
Background technology:
At present, hydraulic hammer through be usually used in constructing road, cut into a mountain, field work such as mining.And the existing all not self-powered device of hydraulic hammer.During use, air compressor machine (or hydraulic press) that the palpus band matches with it and supporting pipe, generating set and cable thereof etc. thereof.Make that the use of hydraulic hammer is very inconvenient.
Summary of the invention:
For solving the awkward defective of hydraulic hammer, the inventor has proposed a kind of hydraulic hammer that portably uses conveniently, is suitable for field work.It comprises: pick rod, pick tube, pick handle; Self is provided with power set hydraulic hammer, and clutch end drives reducing gear by clutch, and reducing gear is connected with power conversion mechanism, and power conversion mechanism is converted to rotatablely moving of decelerator output along axial the moving up and down of pick rod; And the drive piston sends motion to pick rod through hydraulic oil.Because hydraulic hammer itself has power set, in the open air or the relatively poor area of environmental condition use, as long as just be with the hydraulic hammer can.Required plant equipment when having simplified field work greatly.
In the utility model, described PTO is miniature gasoline engine or diesel engine; Described power conversion mechanism comprises the pinion of being located at clutch end, and the inner tooth gearwheel that matches with pinion, with the projection of gear wheel one, be provided with inclined ramp in the projection, the roller bottom that can roll in slideway is connected with the fulcrum that is connected with piston; Described piston is divided into upper and lower two storage areas with the pick tube, is provided with in last storage area and the corresponding fluid infusion piston of pick tube, is provided with pick rod in following bottom, storage area and impacts tup accordingly, is provided with the fluid infusion check valve between upper and lower storage area.In the course of the work, tup impacts pick rod through hydraulic oil, and reaction force passes to hydraulic oil again, is absorbed by hydraulic oil, makes that the vibration of hydraulic hammer is less.Facility had protective effect.
In the utility model, described power conversion mechanism can also be: be located at the pinion of clutch end, and the inner tooth gearwheel that matches with pinion, gear wheel drives crank or eccentric wheel, and crank or eccentric wheel are connected with the fulcrum that is connected with piston.
The course of work of the present utility model is as follows: the power of autogamy minitype motivation machine is exported from bull gear behind decelerator, promoting piston rod with cam (eccentric wheel or crank connecting link) that bull gear axially connects in turning course moves up and down, when piston rod is descending, the fluid infusion closed check valve, the storage area is obstructed up and down for piston, hydraulic oil pressurized and bump and the contacted tup of liquid level, tup is the hammering pick rod again, finishes the acting process.When piston stroking upward, mention tup, the hydraulic oil in tup and the piston space separate space rises synchronously, squeezes simultaneously and opens the fluid infusion check valve, to carrying out fluid infusion in the liquid storage area down, finishes a working cycles.
Description of drawings:
Fig. 1 is embodiment 1 structural representation of the present utility model.
Fig. 2 is embodiment 2 structural representations of the present utility model.
The specific embodiment:
As shown in Figure 1, the hydraulic hammer of present embodiment comprises: pick rod 1, pick tube 2, pick are 3; Hydraulic hammer self is provided with power set 4.Power set 4 are miniature gasoline engine (or diesel engines).Power set are provided with fuel tank 19, are used to start the stay cord 20 of power set, air filter 21, carburetor 22 and engine etc.
Clutch end drives reducing gear by clutch 5, and reducing gear is connected with power conversion mechanism, and power conversion mechanism is converted to rotatablely moving of decelerator output along axial the moving up and down of pick rod; And the drive piston sends motion to pick rod through hydraulic oil.
Power conversion mechanism comprises the pinion 6 of being located at clutch end, and the inner tooth gearwheel 7 that matches with pinion, with the projection 8 of inner tooth gearwheel one, be provided with roller 10 bottoms that inclined ramp 9, can roll in the projection and be connected with the fulcrum 12 that is connected with piston 11 in slideway.
Piston 11 is divided into upper and lower two storage areas with the pick tube, is provided with in last storage area and the corresponding fluid infusion piston 13 of pick tube, is provided with pick rod in following bottom, storage area and impacts tup 14 accordingly, is provided with fluid infusion check valve 15 between upper and lower storage area.In the course of the work, tup impacts pick rod through hydraulic oil, and reaction force passes to hydraulic oil again, is absorbed by hydraulic oil, makes that the vibration of hydraulic hammer is less.The facility tool there is being protective effect.
Fig. 2 has provided embodiment 2 of the present utility model.In the present embodiment, power conversion mechanism is: the pinion 6 of being located at clutch end, and the inner tooth gearwheel 7 that matches with pinion, gear wheel arrives a pair of awl tooth 16 with transmission of power, and by moving crank 17 of awl cingulum or eccentric wheel 18, crank or eccentric wheel are connected with the fulcrum 12 that is connected with piston.The effect of awl tooth is a conversion power outbound course, if power outbound course vertical with pick rod (as in the present embodiment, revolve turn 90 degrees the engine power outbound course) then can omit the awl tooth.The remaining part of present embodiment is identical with embodiment 1.
In the utility model, hydraulic hammer carries power set, as long as just with go up hydraulic hammer can be in the open air or the relatively poor area (as areas without electricity) of environmental condition use, required plant equipment when having simplified field work greatly portably uses conveniently.Any improvement of having done according to the utility model all is interpreted as the end and breaks away from protection domain of the present utility model.
