Abstract
Description
Technical Field
[0001] This utility model relates to the field of excavator operation technology, and in particular to a novel hydraulic breaker housing. Background Technology
[0002] In existing technologies, excavators play a significant role in mining, railways, highways, tunnels, and construction. During construction, fully hydraulic excavators typically utilize hydraulic breakers to effectively break rocks and stones. When the excavator's hydraulic breaker operates, rocks and other materials fly and collide with the outer casing. The outer casing of the hydraulic breaker provides protection and shock absorption, and also contributes to noise reduction.
[0003] However, current silent excavator breaker housings are typically assembled using welding on all four sides and the top and bottom, resulting in numerous seams and weld points. This process is cumbersome, increasing labor costs and negatively impacting environmental protection. Furthermore, the abundance of weld seams makes the housing less robust and durable, prone to breakage and damage over time, thus shortening its lifespan. Additionally, conventional breaker housings generally lack impact protection at the bottom, making it vulnerable to prolonged stress and deformation, further hindering long-term use and increasing wear and tear costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of breaker shell. It adopts an integrated bending design with welding of the front and back seams, which is simple in process, has higher structural strength, is sturdy and durable, and has a shockproof protective sleeve at the bottom, which is not easy to deform or break.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A novel hydraulic breaker housing includes a housing body, a bottom cover fitted onto the bottom of the housing body, and a connecting flange connected to the upper end of the housing body. The outer shell body includes a first bent shell and a second bent shell symmetrically spliced together as a whole. The edges of the first bent shell and the second bent shell that are close together are double-seam welded. A reinforcing member is also provided at the position where the first bent shell, the second bent shell and the connecting flange are connected. A protective cover is also fitted on the bottom of the outer casing near the bottom cover.
[0006] Furthermore, the reinforcing member includes a plurality of reinforcing ribs disposed on the upper side wall of the outer casing and connected to the connecting flange.
[0007] Furthermore, the reinforcing member also includes a reinforcing plate welded to the upper end of the first and second bent shells, and the reinforcing plate is also welded to some of the reinforcing ribs and the connecting flange.
[0008] Furthermore, the reinforcing rib is perpendicular to the outer shell body.
[0009] Furthermore, a mounting base is fitted on the upper end of the connecting flange.
[0010] Furthermore, the first and second bent shells are symmetrically provided with locking plates on the same side, and the bottom cover is engaged with the locking plates.
[0011] Furthermore, positioning cavities are formed on both sides of the outer shell body.
[0012] Furthermore, the lower end of the outer shell body and the fitting area of the protective sleeve are provided with an assembly hole, and the first bent shell and the second bent shell are also provided with a limit hole on the same side.
[0013] Furthermore, both the first and second bent shells have U-shaped cross sections.
[0014] Furthermore, a perforation is provided in the center of the bottom cover.
[0015] By adopting the above technical solution, this utility model has the following beneficial effects: 1. The outer shell of this utility model is spliced by a U-shaped first bent shell and a second bent shell, and is welded with tight double seams on both sides. This greatly reduces the number of welds on the outer shell, which not only simplifies the process and reduces the burden of manual production, thus saving costs and being more environmentally friendly, but also increases the overall strength of the outer shell, making it less prone to breakage, sturdy and durable, and conducive to extending its service life.
[0016] 2. This utility model adds a protective sleeve to the bottom of the outer shell body, which can effectively prevent impact during the operation of the breaker hammer, protect the vulnerable bottom part of the outer shell body, prevent deformation and damage, reduce material consumption, and extend its service life.
[0017] 3. This utility model utilizes multiple reinforcing ribs between the upper sidewall of the outer shell and the connecting flange, as well as a reinforcing plate welded to the upper part of the first and second bent shells. The reinforcing plate is welded to some of the reinforcing ribs and the connecting flange. In this way, the first bent shell, the second bent shell, and the connecting flange can be easily connected to form a whole, thereby improving the overall structural strength and impact resistance of the outer shell, reducing the risk of breakage, and effectively extending its service life.

[0019] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0020] like Figure 1-4 As shown in the figure, this embodiment provides a novel hydraulic breaker housing, which mainly consists of a housing body 1, a bottom cover 2, a connecting flange 3, and a protective sleeve 4. The bottom cover 2 is welded to the bottom of the housing body 1, and a through hole 20 is provided in the center of the bottom cover 2 to allow the steel chisel of the hydraulic breaker to pass through. The connecting flange 3 is welded to the upper end of the housing body 1, and a mounting base 7 is fitted onto the upper end of the connecting flange 3 for assembly with the excavator output end.
[0021] To reduce the number of welds on the outer shell body 1 itself, in this embodiment, the outer shell body 1 is symmetrically spliced together from a first bent shell 11 and a second bent shell 12. Both the first bent shell 11 and the second bent shell 12 have U-shaped cross-sections, with their openings facing each other and their closely fitting edges forming a double-seam weld. This close-fitting double-seam weld significantly reduces the number of welds on the outer shell body 1 itself, simplifying the process, reducing manual labor, saving costs, and being more environmentally friendly. It also increases the overall strength of the outer shell body 1, making it less prone to breakage, sturdy and durable, and contributing to a longer service life.
[0022] To protect the bottom of the outer casing 1, this embodiment also includes a protective sleeve 4 fitted onto the bottom of the outer casing 1 near the bottom cover 2. The lower end of the outer casing 1 and the protective sleeve 4 share a mounting hole 102, which, together with the internally installed breaker body, is secured with bolts or similar fasteners for a stable assembly. This effectively prevents impacts during breaker operation, protects the vulnerable bottom of the outer casing 1 from deformation and damage, reduces material waste, and extends its service life.
[0023] To enhance the assembly stability of the bottom cover 2 and the outer shell body 1, in this embodiment, a retaining plate 100 is symmetrically provided on the same side of the first bent shell 11 and the second bent shell 12, and the bottom cover 2 is engaged with the retaining plate 100 on one side. The connection stability can also be enhanced by pressing or welding.
[0024] To further enhance the overall structural strength, this embodiment also includes reinforcing members at the connection points of the first bent shell 11, the second bent shell 12, and the connecting flange 3. Specifically, the reinforcing members consist of reinforcing ribs 5 and reinforcing plates 6. Eight reinforcing ribs 5 are arranged on both sides, perpendicular to the outer shell body 1, and welded to the upper sidewall of the outer shell body 1, connecting to the connecting flange 3. Two reinforcing plates 6 are welded to the two adjacent edges of the upper ends of the first bent shell 11 and the second bent shell 12, respectively. The width of the reinforcing plates 6 is significantly greater than the weld seams of the first bent shell 11 and the second bent shell 12, and the reinforcing plates 6 are simultaneously welded to the two middle reinforcing ribs 5 and the connecting flange 3. In this way, the first bent shell 11, the second bent shell 12, and the connecting flange 3 can be easily connected to form a whole, thereby improving the overall structural strength and impact resistance of the outer shell body 1, reducing the risk of breakage and damage, and effectively extending its service life.
[0025] Of course, to facilitate the installation and fixation of the internal breaker body, positioning cavities 101 are formed on both sides of the outer shell body 1 in this embodiment, and limiting holes 103 are also formed on the same side of the first bent shell 11 and the second bent shell 12. In this way, the breaker body can form a good limiting and stabilizing effect when installed in the outer shell body 1, ensuring the structural strength after overall assembly.
