Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic breaker hammers, in particular to a noise-reducing hydraulic breaker hammer. Background Art

[0002] A hydraulic breaker, also known as a hydraulic breaker, uses the static pressure of liquid to drive the reciprocating motion of a piston. During the piston stroke, the piston strikes the drill rod at high speed, breaking solid objects such as ore and concrete. A hydraulic pump converts liquid pressure into mechanical energy, while a hydraulic cylinder controls the flow direction and pressure of the liquid through a hydraulic valve, thereby driving the hydraulic breaker's piston. As the piston rod moves outward, the piston head exerts impact force on the material, achieving the desired crushing effect.

[0003] The piston of the existing hydraulic breaker will hit empty when it moves downward. The empty hitting phenomenon will cause impact on the front cylinder body, resulting in a high failure rate and easily shortening the service life of the product.

[0004] An existing patent (publication number: CN205557629U) discloses a hydraulic breaker hammer, which includes a front cylinder body, a middle cylinder body, a rear cylinder body, a reversing valve, a piston and a drill rod. The two ends of the middle cylinder body are respectively connected to the front cylinder body and the rear cylinder body, the drill rod is arranged on the front cylinder body, and the piston is connected to the drill rod; the reversing valve is arranged on the middle cylinder body and cooperates with the piston. It can prevent the hydraulic oil from directly impacting the piston surface from the oil inlet hole by diverting the oil inlet hole. It can reduce the radial component of the force exerted on the piston during operation and extend the service life of the equipment.

[0005] In response to the above problems, although the solution provided by the existing patent can reduce the radial force exerted on the piston during operation to extend the service life of the equipment, when in use, the repeated movement of the piston in the hydraulic cylinder causes the hydraulic cylinder body to easily heat up, and the viscosity of the hydraulic oil flowing inside will be significantly reduced, reducing its lubricity and sealing, and increasing the risk of internal leakage. Summary of the Invention

[0006] The purpose of the utility model is to provide a noise-reducing hydraulic breaker, which can indirectly dissipate heat to the hydraulic cylinder when water passes through the heat absorbing element, thereby effectively reducing the serious heat generation and the resulting reduction in the viscosity of the hydraulic oil.

[0008] The heat dissipation mechanism includes a mounting plate, which is fixed to the right side of the breaker hammer frame. A delivery pump is fixed to the upper surface of the mounting plate by bolts. The input end of the delivery pump is connected to a water inlet pipe, and the output end of the delivery pump is connected to a delivery pipe. The end of the delivery pipe is connected to a heat absorbing component fixed inside the breaker hammer frame, and the inner wall of the heat absorbing component is tightly fitted with a hydraulic cylinder.

[0009] Preferably, one side of the heat absorbing component is connected to a connecting pipe, and the end of the connecting pipe is connected to a water spraying component fixed to the lower end of the breaker hammer frame.

[0014] Preferably, a fixing bolt is installed on the outer surface of the mounting tube, and a fixing rod plug-connected to the limiting hole is fixed to the end of the fixing bolt.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A noise-reducing hydraulic breaker includes a breaker frame 1. Two fixing plates 2 are fixed to the upper surface of the breaker frame 1. Two fixed bearings 3 are embedded in the interior of the two fixing plates 2. A heat dissipation mechanism for cooling the hydraulic hammer is installed on the right side of the breaker frame 1.

[0028] The heat dissipation mechanism includes a mounting plate 4, which is fixed to the right side of the breaker frame 1. A delivery pump 41 is fixed to the upper surface of the mounting plate 4 by bolts. The input end of the delivery pump 41 is connected to a water inlet pipe 42, and the output end of the delivery pump 41 is connected to a delivery pipe 43. The end of the delivery pipe 43 is connected to a heat absorbing component 44 fixed inside the breaker frame 1. The inner wall of the heat absorbing component 44 is tightly fitted with a hydraulic cylinder 45. One side of the heat absorbing component 44 is connected to a connecting pipe 46. The end of the connecting pipe 46 is connected to a water spray component 47 fixed at the lower end of the breaker frame 1. The lower surface of the water spray component 47 is connected to a number of atomizing nozzles 48. The telescopic end of the hydraulic cylinder 45 is fixed with a crushing mechanism for crushing objects. A sound insulation board 5 is installed on the inner wall of the breaker frame 1. The sound insulation board 5 and the breaker hammer frame 1 are an integrated fixed structure.

[0029] By adopting the above technical solution, before using the noise-reducing hydraulic breaker, the breaker and the driving device are first connected through the fixed plate 2 on the breaker frame 1. The fixed bearing 3 is provided to facilitate the rotation of the breaker. When crushing, the delivery pump 41 provided on the mounting plate 4 is started to draw external water in and send it to the heat absorbing element 44 through the delivery pipe 43. Since the heat absorbing element 44 is provided on the outer surface of the hydraulic cylinder 45, the heat absorbing element 44 can absorb the heat generated when the hydraulic cylinder 45 is in operation. When the water passes through the heat absorbing element 44, The heat absorbing component 44 can be cooled, and the hydraulic cylinder 45 can be indirectly cooled, which can effectively reduce the serious heating of the hydraulic cylinder 45 and reduce the viscosity of the hydraulic oil. The water continuously flows into the heat absorbing component 44, and under the action of the connecting pipe 46, the water can flow into the water spraying component 47, and then spray out the mist through the atomizing nozzle 48, thereby reducing the dust generated when the object is broken, thereby improving practicality. The sound insulation board 5 set in the breaker frame 1 can play a certain sound insulation role, thereby reducing the noise generated when the breaker is running.

[0030] Specifically, such as Figure 1-Figure 4 As shown, the crushing mechanism includes a mounting tube 6, which is fixed to the telescopic end of the hydraulic cylinder 45. A crushing drill rod 61 is connected to the bottom of the mounting tube 6. An adjusting rod 62 telescopically connected to the mounting tube 6 is fixed to the upper surface of the crushing drill rod 61. A plurality of limiting holes 63 are equidistantly provided on the outer surface of the adjusting rod 62. A fixing bolt 64 is installed on the outer surface of the mounting tube 6. A fixing rod 65 plugged into the limiting hole 63 is fixed to the end of the fixing bolt 64.

[0031] By adopting the above technical solution, the water inlet pipe 42 is connected to the external water source pipe. When in use, the external driving device drives the hydraulic cylinder 45 inside the breaker hammer frame 1 to operate, thereby driving the breaker drill rod 61 to move and break the object. The fixing bolt 64 set on the mounting tube 6 is loosened to separate the fixing rod 65 and the limiting hole 63 on the adjusting rod 62, thereby releasing the fixation of the adjusting rod 62. In this way, the breaker drill rod 61 can be pulled, and the length of the breaker drill rod 61 can be adjusted, which is convenient for use.

[0032] Working principle: The external driving device drives the hydraulic cylinder 45 inside the breaker frame 1 to operate, thereby driving the breaker rod 61 to move and break the object. The delivery pump 41 draws external water in and delivers it to the heat absorber 44 through the delivery pipe 43. Since the heat absorber 44 is arranged on the outer surface of the hydraulic cylinder 45, the heat absorber 44 can absorb the heat generated by the operation of the hydraulic cylinder 45, cool the heat absorber 44, and indirectly dissipate the heat of the hydraulic cylinder 45, which can effectively reduce the serious heating of the hydraulic cylinder 45, thereby reducing the viscosity of the hydraulic oil. Down, water can flow into the water spray part 47, and spray mist through the atomizing nozzle 48, thereby reducing the dust generated when the object is broken. The sound insulation board 5 set in the breaker frame 1 can play a certain sound insulation role, thereby reducing the noise generated when the breaker is running. The fixing bolt 64 set on the mounting tube 6 is loosened to separate the fixing rod 65 and the limiting hole 63 on the adjusting rod 62, thereby releasing the fixation of the adjusting rod 62, so that the breaker drill rod 61 can be pulled, and the length of the breaker drill rod 61 can be adjusted.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
