Description

Technical Field

[0001] The utility model relates to the technical field of mine hydraulic saws, in particular to a mine hydraulic saw. Background Technique

[0002] The mine hydraulic saw, also called the hydraulic rock saw, is a large hydraulic-driven circular saw designed for excavators. It is mainly used for cutting hard rocks, including granite, basalt, and reinforced concrete. This product is mainly used in earthwork projects, rock excavation, building demolition, mining and quarrying, landscaping and other projects. The hydraulic rock saw can be applied to excavators of various models and tonnages, and provides various models of hydraulic rock saws to meet different working needs. The design of the hydraulic rock saw makes the work easier, suitable for various engineering scenarios, and is an efficient and practical engineering mechanical equipment. The working principle of the existing mine hydraulic saw can be summarized into two main parts: hydraulic transmission and mechanical cutting. The hydraulic motor is the core component. It continuously inhales and discharges hydraulic oil to generate a high-pressure liquid flow. The high-pressure liquid flow drives the saw blade to rotate through the transmission shaft. The rotation speed and direction of the saw blade can be precisely adjusted through the control system to adapt to different cutting requirements. When installing the saw blade on the traditional mine hydraulic saw, the saw blade needs to be fixed by a large number of bolts, which is very inconvenient for disassembly and assembly and affects the cutting efficiency. For this reason, we propose a mine hydraulic saw. Content of the Utility Model

Uniformly distributed limit holes are provided in the middle of the saw blade 34. The middle part of the outer surface of the limit post 37 is fitted with the inner wall of the limit hole, providing a basis for the limitation of the saw blade 34. The quick-release mechanism 3 further includes fixing bolts 38. The fixing bolts 38 are threadedly connected to the middle of the inside of the mounting block 2. The upper end of the outer surface of the fixing bolt 38 is threadedly connected to the inner wall of the end cap 35, which can quickly squeeze the locking block 31 and fix the end cap 35, realizing the quick disassembly and assembly of the saw blade 34. A chamfer 1 is provided at the rear end of the fixing bolt 38, and chamfers 2 are provided at the front ends of the four locking blocks 31, facilitating the entry of the fixing bolt 38. The quick-release mechanism 3 further includes a hydraulic motor 1 39. The hydraulic motor 1 39 is arranged at the front end inside the mounting box 1. The front end of the output shaft of the hydraulic motor 1 39 is fixedly connected to the rear end of the mounting block 2, providing stable drive for the high-speed rotation of the saw blade 34. It further includes a splash guard 4. The splash guard 4 is arranged above the saw blade 34. The outer edge of the saw blade 34 is fitted with the inner wall of the splash guard 4, preventing dust and rock particles from splashing during cutting. It further includes a hydraulic motor 2 5 and a connecting block 6. The hydraulic motor 2 5 is arranged at the rear end inside the mounting box 1. The connecting block 6 is arranged at the upper end of the output shaft of the hydraulic motor 2 5. Pins are provided at the upper end inside the connecting block 6, facilitating the adjustment of the cutting direction and the fixation of the machine body. A quick-release mechanism is provided, which can quickly fix and release the saw blade by squeezing the locking block, and quickly form a limit on the saw blade through the limit post, preventing the saw blade from loosening, realizing the quick disassembly and assembly of the saw blade, and improving the cutting efficiency of the rock.

[0026] The working principle of a mine hydraulic saw provided by the utility model is as follows: When using the mine hydraulic saw to cut rocks, the body is connected to the robotic arm of the excavator through the pin shaft on the connecting block 6. The hydraulic motor 1 39 and the hydraulic motor 2 5 are connected to the hydraulic pump station of the excavator through oil pipes. Then, the saw blade 34 is installed. The saw blade 34 is sleeved on the middle part of the outer surface of the mounting block 2 through the mounting hole in the middle. Then, the end cover 35 is inserted into the middle part of the front end of the mounting block 2 through the guiding column 36. At this time, as the end cover 35 is inserted, the limiting column 37 slowly penetrates through the mounting hole in the middle of the saw blade 34 and finally inserts into the middle of the inside of the mounting block 2. Then, the fixing bolt 38 is aligned with the center of the end cover 35, and the fixing bolt 38 is rotated so that the fixing bolt 38 slowly enters the inside of the end cover 35 and is threadedly connected to the inner wall of the end cover 35. As the fixing bolt 38 moves backward, the chamfer 1 at the rear end of the fixing bolt 38 contacts and presses the chamfer 2 at the front end of the four locking blocks 31, causing the four locking blocks 31 to move outward synchronously, and the sliding column 32 also moves outward accordingly. The spring 33 is compressed under force until the fixing bolt 38 moves to a suitable position. At this time, the rear end of the locking block 31 closely adheres to the front end of the saw blade 34, forming a preliminary fixation for the saw blade 34. The inner walls of the end cover 35 and the mounting block 2 are both threadedly connected to the outer surface of the fixing bolt 38. The rear end of the end cover 35 and the front end of the mounting block 2 clamp the saw blade 34, and the limiting column 37 forms a limit for the saw blade 34 and fixes it. Only by rotating one fixing bolt 38 can the saw blade 34 be quickly fixed. Then, the hydraulic pump station of the excavator pumps hydraulic oil into the hydraulic motor 1 39, causing the output shaft of the hydraulic motor 1 39 to rotate at a high speed, driving the mounting block 2 and the saw blade 34 to rotate at a high speed, thereby cutting rocks. When the cutting direction needs to be adjusted, the hydraulic pump station pumps hydraulic oil into the hydraulic motor 2 5, and the output shaft of the hydraulic motor 2 5 rotates, driving the entire body to rotate, realizing the adjustment of the cutting direction. When the saw blade 34 needs to be removed, only the fixing bolt 38 needs to be reversed and the fixing bolt 38 is taken out. The locking block 31 is not stressed, and the spring 33 rebounds to drive the locking block 31 and the sliding column 32 back to their original positions. The locking block 31 retracts back into the inside of the mounting block 2 again, and then the end cover 35 is removed, and the saw blade 34 can be quickly removed.

[0027] It should be noted that the hydraulic motor 1 39 and the hydraulic motor 2 5 disclosed in the above embodiments are both MMF044DAFHABNNN hydraulic motors, and the external hydraulic pump station controls the operation of the hydraulic motor 1 39 and the hydraulic motor 2 5 using the commonly used methods in the prior art.

[0028] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
