Abstract
The invention relates to a hydraulic down-hole hammer, aims to achieve the purposes of reducing the energy consumption of the conventional down-hole hammer and improving the operational efficiency of the conventional down-hole hammer, and belongs to the technical field of hole-forming construction machinery. The hydraulic down-hole hammer comprises a housing and a hydraulic motor arranged in the housing, wherein a base is fixedly connected with crushing teeth in a vertically superimposition manner and is arranged below the housing. The hydraulic down-hole hammer is characterized in that the hydraulic motor is in bolted connection with the housing through a motor base in a fixed manner; a drive gear is connected with the shaft spline of the hydraulic motor and meshed with a first eccentric gear; the first eccentric gear and a second eccentric gear are meshed with each other, coaxially arranged with corresponding eccentric blocks respectively, integrally fixed with the corresponding eccentric blocks through bolts; the two ends of each shaft are respectively fixedly connected the housing through bearings. The invention has the benefits as follows: the hydraulic down-hole hammer takes a liquid as a working medium by virtue of the hydraulic motor, thereby saving energy, and achieves the function of crushing rocks by virtue of high-frequency oscillation forces produced by the rotary motion of the eccentric gears, thereby improving the construction efficiency.
Description
Technical field
The present invention relates to the catalase machinery in a kind of drilling construction, relate in particular to the hydraulic hole drilling hammer that a kind of vibratory forces of utilizing eccentric wheel to rotate and produce reaches fractured rock, belong to drilling construction machinery down-the-hole hammer technical field.
Background technology
In the engineering construction at present, mainly contain weight for the catalase in the drilling construction, utilize external force that the hammer body of iron and steel manufacturing is sling exactly, then external force is shed, utilize weight freely falling body bump rock, its dust cycle is long, efficient is low; Another kind is air percussion hammer, utilizes gases at high pressure to provide power to make the former earthquake motion of hammer body exactly, adopts compressed air as power source, at the bottom of compressed air promotes that the down-the-hole hammer breaks rock, return slag and broken landwaste blown out the hole.Air percussion hammer is greatly improved the efficient of drilling construction, but the compressed air utilization rate is low, and energy consumption is big.Hydraulic system is big owing to its transmission force, and is easy to transmit and configuration, extensive use in each industry and civilian industry.Be energy consumption and the raising operating efficiency that reduces the down-the-hole hammer, adopt hydraulic system to replace compressed air, by hydraulic cylinder and hydraulic motor the pressure of liquid can be converted to mechanical energy, obtain the straight reciprocating motion or the gyration that need, be scientific and technical personnel's problem of making great efforts to explore in the industry.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of energy consumption province, hydraulic hole drilling hammer that operating efficiency is high are provided.
For achieving the above object, the technical scheme that adopts is: hydraulic hole drilling hammer, comprise housing, place the hydraulic motor in the housing, base and crushing teeth be the stacked below of fixedlying connected and placing described housing up and down, it is characterized in that: described hydraulic motor is connected and fixed by motor base and housing bolt, driving gear is connected with hydraulic motor axle spline, and described driving gear and first eccentric gear are connected with a joggle, and described first eccentric gear and second eccentric gear are meshing with each other; Described first eccentric gear and the coaxial setting of first eccentric block, bolt is connected and fixed, described second eccentric gear and the coaxial setting of second eccentric block, bolt is connected and fixed, and fixedly connected with described housing by bearing respectively in the two ends of axle.
The axis of described first eccentric gear and second eccentric gear be arranged in parallel with the rotating shaft three of described hydraulic motor.
Be equipped with a plurality of eccentric orfices respectively on described first eccentric gear and second eccentric gear.
The invention has the beneficial effects as follows: utilize hydraulic motor with liquid as the working media transferring power, saved the energy; Utilize eccentric wheel to rotate the function that the high frequency oscillation power that produces reaches fractured rock, improved efficiency of construction.

The specific embodiment
Fig. 1 and Fig. 2 are hydraulic hole drilling hammer structural representation of the present invention, Fig. 3 is first/or the structural representation of second eccentric gear.By diagram as seen, hydraulic hole drilling hammer, comprise housing 1, place the hydraulic motor 3 in the housing 1, about in the of 10 the stacked below of fixedlying connected and placing described housing 1 with crushing teeth for base 9, it is characterized in that: described hydraulic motor 3 is connected and fixed by motor base 2 and housing 1 bolt, 3 splines of driving gear 4 and hydraulic motor are connected, and described driving gear 4 and first eccentric gear 5 are connected with a joggle, and described first eccentric gear 5 and second eccentric gear 5 ' are meshing with each other; Described first eccentric gear 5 and the 6 coaxial settings of first eccentric block, bolt 8 is connected and fixed, described second eccentric gear 5 ' and 6 ' the coaxial setting of second eccentric block, bolt 8 is connected and fixed; The axis of described first eccentric gear 5 and second eccentric gear 5 ' (being the bolster of corresponding eccentric block 6), fixedly connected with described housing 1 by bearing 11 respectively in the two ends of axle.
The axis of described first eccentric gear 5 and second eccentric gear 5 ' be arranged in parallel with the rotating shaft three of described hydraulic motor 3.
Be equipped with a plurality of eccentric orfices 12 respectively on described first eccentric gear 5 and second eccentric gear 5 ', regulate eccentric with size and the hole count of described eccentric orfice 12.
A kind of hydraulic hole drilling hammer of the present invention, its operating principle are that the eccentric block that relies on high frequency to rotate produces the high-frequency vibration of vertical direction, thereby drive base in the broken rock punching of rock surface.
During work, hydraulic motor 3 drives driving gear 4, driving gear 4 drives two eccentric gears 5/5 ' and rotates, each eccentric gear 5 respectively and corresponding eccentric block 6 coaxial settings, and by three bolts, 8 fixedly connected being integral, when eccentric gear 5 rotates, can drive corresponding eccentric block 6 and rotate together, as shown in Figure 1.Because the eccentric block symmetric arrangement, counteractings of will meeting of backward rotation, the eccentric force that horizontal direction produces only stays the centrifugal force that the high frequency of vertical direction changes, thereby drives crushing teeth 10 on the base 9 at the rock surface high-frequency vibration, realizes breaking the rock drilling construction.
