Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and more specifically, to a rock cutting machine used in construction. Background Technology

[0002] In modern construction, rock cutting is a fundamental and crucial engineering process. With the continuous advancement of urbanization and infrastructure development, scenarios involving rock excavation and cutting are increasingly common in construction projects, such as tunnel excavation, foundation treatment, and mountain development, all of which require precise cutting of hard rock. Rock cutting machines, as specialized machinery for cutting various types of rock materials, directly impact the overall construction progress and project quality through their efficiency and cutting quality, thus occupying an irreplaceable and vital position in construction.

[0003] Most rock cutting machines on the market currently use diamond saw blades or alloy cutter heads as cutting components. These components are driven by a motor or hydraulic system to rotate or reciprocate at high speed, thus cutting the rock. These machines typically include a frame, power system, transmission mechanism, cutting blades, and a feed device. In actual operation, the operator controls the feed device to gradually advance the cutting blades into the rock surface, thereby completing the intended cutting task. However, these machines are mostly designed for laboratory environments and do not consider the needs of outdoor working conditions.

[0004] However, existing rock cutting machines still have some shortcomings in their mechanical structure design. On the one hand, the cutting tool installation structure of traditional cutting machines is relatively fixed, lacking adjustment flexibility. When it is necessary to change the cutting angle or cutting depth, it is often necessary to stop the machine for complex mechanical adjustments, resulting in reduced work efficiency. Moreover, the large amount of heat generated during the cutting process cannot be dissipated in time, which can easily cause the tool to overheat and wear more quickly. On the other hand, the saw blades of existing equipment are mostly of a single structure, with a relatively simple distribution of cutting teeth and grinding structure. This makes them prone to vibration and sway when cutting hard rocks, affecting cutting efficiency and making them insufficiently adaptable to the complexity and high-load requirements of outdoor construction sites.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a rock cutting machine for building construction to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows: A rock cutting machine for construction includes: a handle for operator gripping and control; a housing located at the top of the handle for housing an internal transmission assembly; a transmission assembly located at the top of the housing for changing the transmission direction and providing output power; an auxiliary handle located on one side of the transmission assembly for providing auxiliary grip to facilitate hand-held cutting during construction; a protective shell fixedly located on the other side of the transmission assembly for protecting the operator from rock cutting debris; a power assembly located inside the housing for providing power for rock cutting; and a cutting assembly located on one side of the protective shell and connected to the power assembly for cutting rock materials during construction.

[0008] Furthermore, to ensure the stability and lifespan of the transmission assembly, the transmission assembly includes a mounting shell located at the top of the machine body. A driven shaft connected to the cutting assembly is passed through one side of the top of the mounting shell, and a first bevel gear is fixedly mounted on the outer side of one end of the driven shaft. Bolt holes for engaging with auxiliary handles are provided at both ends of the top of the mounting shell. A drive shaft connected to the power assembly is passed through the middle of the bottom of the mounting shell, and a second bevel gear meshing with the first bevel gear is fixedly mounted at the top of the drive shaft. The number of teeth of the second bevel gear is less than that of the first bevel gear, and the axes of the two bevel gears are arranged perpendicularly to achieve vertical transmission with speed reduction and torque increase. An annular groove is provided at the bottom of the mounting shell near the protective shell, and a heat dissipation cavity that engages with the annular groove is provided on the inner side of the bottom of the mounting shell. A heat dissipation fan blade is fitted at the bottom of the drive shaft to drive air out of the annular groove for heat dissipation and cooling. At the same time, the annular groove is located behind the protective shell to effectively prevent cutting dust from entering the transmission mechanism.

[0009] Furthermore, in order to achieve high efficiency and stability in the cutting process, the power assembly includes a drive motor located inside the machine housing, a drive shaft at the top of the drive motor, and a wire sleeve at the bottom of the drive motor to guide the drive motor wires out from the middle of the handle to connect to an external power source.

[0010] Furthermore, to achieve efficient and convenient rock cutting operations, the cutting assembly includes a first flange disposed on one side of the protective shell, a cutting saw blade disposed on one side of the first flange, a second flange disposed on one side of the cutting saw blade, and a locking nut disposed on one side of the second flange; the cutting saw blade includes a main saw blade disposed on one side of the first flange, a first grinding saw blade disposed on one side of the main saw blade, and a second grinding saw blade disposed on the other side of the main saw blade; the cross-section of the first grinding saw blade is configured with an arc-shaped edge structure, and the arc-shaped edge fits against the outer peripheral edge of the main saw blade. The saw blade is designed to enhance the grinding effect on rocks, and the first and second grinding saw blades have the same structure. The main saw blade is designed as a disc-shaped structure, with several cutting teeth evenly distributed on the outer periphery of the disc-shaped structure. The tips of the cutting teeth are fixed with diamond abrasive, and the cross-section of the diamond abrasive is trapezoidal, which is used to enhance the cutting ability of hard rocks. Several circumferentially distributed damping grooves are opened on the radial outer side of the main saw blade. The damping grooves are arc-shaped and extend in the radial direction, which are used to reduce vibration during rock cutting and extend service life.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model has a scientific and novel structure. By optimizing the design of the transmission component, power component and cutting component, it can achieve efficient and stable rock cutting operations. The overall design not only improves the adaptability and reliability of the equipment, but also significantly improves the cutting efficiency and cutting quality. It is particularly suitable for complex site environments in building construction.

[0012] 2. By setting up transmission and power components, the direction of power transmission is changed and the torque is increased, converting high-speed, low-torque power into low-speed, high-torque power to meet the high load requirements of rock cutting; at the same time, the cooling system of the annular groove and cooling fan blades effectively reduces the temperature of the transmission mechanism, enabling the cutting machine to operate stably for a long time.

[0013] 3. By setting up cutting components, efficient and convenient rock cutting is achieved. The multi-layer saw blade structure and specially designed shock-absorbing grooves effectively reduce vibration during the cutting process, improve cutting accuracy and saw blade life; the combined use of diamond abrasive and cutting teeth significantly enhances cutting efficiency and surface quality, meeting the high-intensity rock cutting needs in construction.

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a rock cutting machine for building construction is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-7As shown, a rock cutting machine for building construction according to an embodiment of the present invention includes: Handle 1 is used by the operator to grip and control it; The housing 2 is located at the top of the handle 1 and is used to house the internal transmission components 3; The transmission component 3 is located at the top of the housing 2 and is used to change the transmission direction and provide output power. An auxiliary handle 4 is located on one side of the transmission assembly 3 and is used to provide an auxiliary grip to facilitate hand-held cutting during construction. The protective shell 5 is fixedly installed on the other side of the transmission assembly 3 to protect the operator from rock cutting debris; The power unit 6 is located inside the casing 2 and is used to provide power for rock cutting. The cutting component 7, located on one side of the protective shell 5 and connected to the power component 6, is used for cutting rock materials during construction.

[0020] In one embodiment, the transmission assembly 3 includes a mounting shell 301 disposed at the top of the housing 2. A driven shaft 302 connected to the cutting assembly 7 is provided through one side of the top of the mounting shell 301. A first bevel gear 303 is fixedly disposed on the outer side of one end of the driven shaft 302 (the cutting assembly 7 is sleeved on the outer side of the other end of the driven shaft 302 and fixedly connected to the locking nut 704). Bolt holes that can cooperate with the auxiliary handle 4 are provided at both ends of the top of the mounting shell 301. A drive shaft 304 connected to the power assembly 6 is provided through the middle of the bottom end of the mounting shell 301. A second bevel gear that meshes with the first bevel gear 303 is fixedly disposed at the top of the drive shaft 304. The number of teeth of the second bevel gear 305 is less than that of the first bevel gear 303. The axes of the two bevel gears are arranged vertically to achieve vertical transmission with speed reduction and torque increase. An annular groove 306 is provided at the bottom end of the mounting shell 301 near the protective shell 5. A heat dissipation cavity that matches the annular groove 306 is provided on the inner side of the bottom end of the mounting shell 301. A heat dissipation fan blade 307 is sleeved at the bottom end of the drive shaft 304 (one end of the drive shaft 304 is fixedly connected to the drive shaft 602 through a coupling). This is used to drive air to be discharged from the annular groove 306 to achieve heat dissipation and cooling. At the same time, the annular groove 306 is located behind the protective shell 5 to effectively block cutting dust from entering the transmission mechanism, thereby ensuring the stability and life of the transmission component 3.

[0021] The working principle of the transmission assembly 3 is as follows: the drive motor 601 drives the drive shaft 304 to rotate via the drive shaft 602. The second bevel gear 305 at the top of the drive shaft 304 meshes with the first bevel gear 303 on the driven shaft 302. Since the number of teeth of the second bevel gear 305 is less than that of the first bevel gear 303, vertical transmission with reduced speed and increased torque is achieved, thereby converting high-speed, low-torque power into low-speed, high-torque power to meet the high-load requirements of rock cutting. At the same time, the cooling fan blades 307 at the bottom of the drive shaft 304 rotate with the shaft, exhausting air from the annular groove 306, effectively reducing the temperature of the transmission mechanism, and the protective shell 5 prevents cutting dust from entering the transmission assembly 3, thereby ensuring the stability and lifespan of the transmission assembly 3.

[0022] In one embodiment, the power assembly 6 includes a drive motor 601 disposed inside the housing 2. The top of the drive motor 601 is provided with a drive shaft 602, and the bottom of the drive motor 601 is provided with a wire sleeve 603, which is used to guide the wire of the drive motor 601 out from the middle of the grip handle 1 (the grip handle 1 has a wire groove in the middle) to connect to an external power source, thereby ensuring the efficiency and stability of the cutting process.

[0023] The working principle of the power assembly 6 is as follows: an external power source supplies power to the drive motor 601 through the wires inside the wire sleeve 603. The drive motor 601 transmits power to the transmission assembly 3 through the drive shaft 602. The wire sleeve 603 not only ensures the orderly arrangement of the wires but also prevents the wires from being pulled and damaged during operation, thus ensuring the reliability and safety of the power assembly. The drive motor 601 uses a high-performance motor, which can provide stable high-power output to meet the high load requirements of rock cutting, thereby ensuring the efficiency and stability of the cutting process.

[0024] In one embodiment, the cutting assembly 7 includes a first flange 701 disposed on one side of the protective shell 5, a cutting saw blade 702 disposed on one side of the first flange 701, a second flange 703 disposed on one side of the cutting saw blade 702, and a locking nut 704 disposed on one side of the second flange 703. The cutting saw blade 702 includes a main saw blade 7021 disposed on one side of the first flange 701, a first grinding saw blade 7022 disposed on one side of the main saw blade 7021, and a second grinding saw blade 7023 disposed on the other side of the main saw blade 7021. The cross-section of the first grinding saw blade 7022 is configured with an arc-shaped edge structure, which fits against the outer peripheral edge of the main saw blade 7021 to enhance the grinding effect on the rock. The first grinding saw blade 7022 and the second grinding saw blade 7023 have the same structure (the outer sides of the first grinding saw blade 7022 and the second grinding saw blade 7023 have several bolt holes arranged in a circular pattern, which are fixedly connected to the first flange 701 and the second flange 703 respectively by bolts); the main saw blade 7021 is configured as a disc-shaped structure, and several cutting teeth are evenly distributed on the outer circumference of the disc-shaped structure. The tips of the cutting teeth are fixed with diamond abrasive. The cross-section of the diamond abrasive is trapezoidal, which is used to enhance the cutting ability of hard rocks; several circumferentially distributed damping grooves are opened on the radial outer side of the main saw blade 7021. The damping grooves are arc-shaped grooves that extend in the radial direction, which are used to reduce vibration during rock cutting to extend service life, thereby achieving efficient and convenient rock cutting operations.

[0025] The working principle of the cutting assembly 7 is as follows: the driven shaft 302 of the transmission assembly 3 drives the cutting saw blade 702 to rotate at high speed, and the diamond abrasive cutting teeth on the main saw blade 7021 perform the main cutting on the rock. The grinding saw blades 7022 and 7023 on both sides grind and finish the cutting surface through their arc-shaped edge structure, ensuring the flatness and smoothness of the cutting surface, thereby improving the cutting quality. Several circumferentially distributed shock-absorbing grooves are opened on the radial outer side of the main saw blade 7021. These shock-absorbing grooves are arc-shaped grooves that extend in the radial direction, effectively absorbing the vibration energy during the cutting process, improving the cutting accuracy and the service life of the saw blade, thereby ensuring the smoothness and efficiency of the cutting process. The first flange 701 and the second flange 703 fix the cutting saw blade 702 with nuts, ensuring the stability and safety of the saw blade when rotating at high speed, thereby achieving efficient and precise rock cutting.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] In practical applications, the operator holds the handle 1 and auxiliary handle 4 with both hands respectively. After turning on the power, the drive motor 601 drives the cutting saw blade 702 to rotate at high speed. The protective shell 5 effectively blocks the spatter generated during the cutting process, protecting the operator's safety. The power transmission direction is changed and the torque is increased through bevel gear transmission, and the annular groove 306 ensures stable operation of the equipment for extended periods. Furthermore, the multi-layer saw blade structure combined with shock absorption design makes the cutting process smoother and more efficient, making it particularly suitable for cutting various rock materials on construction sites. It allows operators to adjust the cutting depth and angle according to actual needs, ensuring smooth rock cutting operations and improving construction efficiency.
