Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically a detachable protective mechanism and its construction cutting device. Background Technology

[0002] Cutting is a common process in fields such as construction, building materials processing, and metal cutting. During such operations, high-speed cutting tools generate a large amount of high-speed flying debris and dust, which not only pollutes the working environment but also poses a threat to the safety of operators. At the same time, the sharp noise generated by cutting also harms the physical and mental health of operators.

[0003] In existing technologies, fixed protective covers are often installed on cutting equipment to address these problems; however, these fixed protective covers have the following drawbacks:

[0004] First, the equipment is usually fixed by welding or multi-point bolt tightening, which is inconvenient to disassemble and assemble, resulting in limited working space for cleaning the inside of the equipment, changing tools or maintaining and cumbersome operation.

[0005] Secondly, the part of the protective cover near the working area is subjected to long-term impact from debris, making it extremely prone to wear, and the fixed structure makes it difficult to inspect and replace the wear-resistant parts.

[0006] Third, ordinary protective covers often lack effective sound insulation design and have poor noise reduction effect; in order to address the shortcomings of the existing technology, this utility model provides a detachable protective mechanism and its building cutting device to solve the above problems. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This embodiment discloses a detachable protective mechanism, according to the attached... Figure 1 To be continued Figure 6 As shown, the device includes a protective platform 1 and a protective cover 2 installed on the protective platform 1. A positioning mechanism 3 is provided between the protective cover 2 and the protective platform 1. The protective cover 2 is detachably installed on the protective platform 1 through the positioning mechanism 3. An installation groove 11 is provided on the upper surface of the protective platform 1. An installation plate 41 is embedded inside the installation groove 11. A baffle 4 for blocking debris is fixedly connected to the installation plate 41. The surface of the baffle 4 is provided with a wear-resistant plate 5. The protective cover 2 is made of sound insulation material, specifically high-density sound insulation cotton and thin metal plate composite. After the protective cover 2 is installed through the positioning mechanism 3, the bottom of the protective cover 2 fits against the edge of the installation groove 11, limiting the installation plate 41 and preventing the installation plate 41 from falling out of the installation groove 11.

[0038] According to the appendix Figure 1 , 3 As shown, furthermore, several sets of closed curtains 21 are installed at the front opening of the protective cover 2. The closed curtains 21 are made of flexible rubber material, which can not only ensure that the operator's hands or tools can be inserted into the protective cover 2 to carry out the work, but also effectively block cutting debris from flying out of the opening. At the same time, the flexible material can avoid scratching the operator.

[0039] According to the appendix Figure 1 , 3 As shown, the top of the protective cover 2 is provided with a vacuum cleaner interface 22, which is fixed to the top of the protective cover 2 by a threaded connection. After the vacuum cleaner interface 22 is connected to an external vacuum cleaner through a pipe, a negative pressure environment is formed inside the protective cover 2 when the vacuum cleaner is working, which sucks in the dust and fine debris generated during the cutting process, thereby reducing the dust concentration in the working environment.

[0040] According to the appendix Figure 1 , 3As shown in Figures 4 and 6, the positioning mechanism 3 specifically discloses that it includes a limiting rail 31, a limiting groove 32, and a locking assembly 33. The limiting rail 31 is made of stainless steel and can be fixedly connected to the protective platform 1 by bolts or welding. The limiting groove 32 is opened on the side of the protective cover 2, and its shape is adapted to the limiting rail 31. The protective cover 2 is initially positioned by the engagement of the limiting groove 32 and the limiting rail 31, which restricts the movement of the protective cover 2 in the horizontal direction. The locking assembly 33 is set on the protective platform 1 and is used to lock and fix the protective cover 2.

[0041] According to the appendix Figure 2 As shown, the wear-resistant plate 5 specifically discloses that includes a polyethylene plate 51 fixedly connected to the baffle 4 and a rubber plate 52 fixedly connected to the polyethylene plate 51; the polyethylene plate 51 is bonded to the surface of the baffle 4 with epoxy resin adhesive, and has a thickness of 8-12mm. It has excellent wear resistance and can block the impact and wear of cutting debris on the baffle 4; the rubber plate 52 is fixed to the polyethylene plate 51 with bolts, and has a thickness of 3-5mm. It has good elasticity and can buffer the splashing debris, reduce the rebound force of the debris. At the same time, the surface of the rubber plate 52 is provided with anti-slip texture, which can further enhance the wear resistance.

[0042] It is worth emphasizing that the protective cover 2 has a honeycomb cavity inside. The honeycomb structure can effectively enhance the structural strength of the protective cover 2. At the same time, the sound insulation effect of the protective cover 2 is further improved by utilizing the sound insulation principle of the honeycomb structure. According to the test, at the standard test distance position, the protective cover 2 can reduce the noise generated by the cutting operation from 85-95dB to below 60dB, which meets the industrial operation noise standard.

[0043] According to the appendix Figure 4 , 6 As shown, it is particularly important to emphasize that the protective cover 2 has a locking hole 23 at the position corresponding to the locking component 33. The inner diameter of the locking hole 23 is adapted to the outer diameter of the locking rod 334. The locking component 33 includes a guide rail frame 331, an adjusting block 332, a screw 333, and a locking rod 334. The guide rail frame 331 is fixedly connected to the protective platform 1 by welding. The adjusting block 332 is slidably connected to the guide rail frame 331, and the guide rail frame 331 restricts the rotation of the adjusting block 332. The screw 333 is threadedly connected to the middle of the adjusting block 332. One end of the screw is rotatably connected to the guide rail frame 331 through a bearing, and the other end extends to the outside of the guide rail frame 331. The locking rod 334 adopts a cylindrical structure and is fixedly connected to the adjusting block 332 near the protective cover 2 by welding. When the screw 333 is rotated to drive the adjusting block 332 to move towards the protective cover 2, the locking rod 334 is inserted into the locking hole 23, thereby locking the position of the protective cover 2.

[0044] According to the appendix Figure 6As shown, it is worth emphasizing that the screw 333 is equipped with a handle 3331. The handle 3331 is made of plastic and is fixed to the end of the screw 333 by a key connection. Its surface is provided with anti-slip texture. The operator can reduce the operating force by rotating the handle 3331 to drive the screw 333 to rotate. The length of the handle 3331 is 100-150mm, which is convenient for the operator to hold.

[0045] This embodiment also discloses a building cutting device, according to the appendix. Figure 1 To be continued Figure 6 As shown, the device includes the aforementioned detachable protective mechanism and a cutting host. The cutting host is fixed to the protective platform 1 by a bracket. The cutting blade of the cutting host is located inside the protective cover 2. The control switch of the cutting host can extend to the outside of the protective cover 2 for easy operation by the operator.

[0046] Example 1: This example uses the cutting of steel bars for construction as an example, combined with the attached... Figure 1 To be continued Figure 6 Detailed explanation of the workflow: The workflow is as follows:

[0047] Installation preparation: Embed the mounting plate 41 into the mounting slot 11 of the protective platform 1, ensuring that the upper surface of the mounting plate 41 is flush with the upper surface of the protective platform 1;

[0048] Installation of protective cover 2: Align the limiting groove 32 at the bottom of the protective cover 2 with the limiting rail 31 on the protective platform 1, and push the protective cover 2 to the designated position along the limiting rail 31. At this time, the bottom of the protective cover 2 is in contact with the edge of the mounting plate 41. Turn the handle 3331 to drive the screw 333 to rotate. The screw 333 drives the adjusting block 332 to move along the guide rail frame 331, so that the locking rod 334 is inserted into the locking hole 23 on the protective cover 2, and the locking and fixing of the protective cover 2 is completed.

[0049] Auxiliary device connection: Install the closed curtain 21 at the front opening of the protective cover 2, and ensure that the adjacent closed curtains 21 meet the requirements; connect the vacuum cleaner pipe to the vacuum cleaner interface 22 on the top of the protective cover 2, and turn on the vacuum cleaner to perform a test vacuum;

[0050] Operation process: The operator inserts the steel bar into the protective cover 2 through the gap between the closed curtains 21, aligns it with the blade of the cutting host, and turns on the cutting host to carry out the cutting operation; during the cutting process, the baffle 4 and the wear-resistant plate 5 prevent debris from flying, the vacuum cleaner sucks up the dust and fine debris, and the protective cover 2 plays a role in sound insulation.

[0051] Work completed: Turn off the cutting host and vacuum cleaner, remove the cut steel bars, and clean the remaining debris inside the protective cover 2.
