Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a material cutting device for civil construction. Background Art

[0002] In the field of civil construction, material cutting is a crucial operation process, which involves the precise and efficient cutting of various building materials such as steel bars, stones, concrete, etc. The sparks, spatters, dust and other harmful substances generated during the cutting process will pose a serious threat to the operator's eyes.

[0003] Among the existing protective measures, protective shields and goggles are two common means of protection. Although protective shields can effectively block harmful substances generated during the cutting process, they need to be handheld for operation, which leads to frequent removal and placement during continuous processing, greatly reducing the operating efficiency and increasing the workload of operators. On the other hand, although goggles avoid the problem of frequent removal and placement of protective shields, due to their design limitations, such as poor light transmittance and dim light, operators have poor vision when wearing goggles, which not only affects the cutting accuracy, but also increases the difficulty of operation, making it inconvenient to remove and operate materials. For this reason, we propose a material cutting device for civil construction. Utility Model Content

[0004] A technical problem to be solved by the present application is: how to design an automatically deployed goggle system that can automatically shield the cutting position during the cutting process and effectively protect the operator's eye safety.

[0005] In order to solve the above technical problems, the present application provides a material cutting device for civil construction, including a base and a main cutting wheel, and also includes

[0006] Goggles are rotatably mounted on the main cutting wheel. In the initial non-cutting state, the goggles are folded at the side of the main cutting wheel;

[0007] The linkage component is installed between the goggles and the base. When the main cutting wheel is pressed down for cutting, the linkage component drives the goggles to rotate and expand to cover the cutting position;

[0008] Two rotating shafts are rotatably mounted on the main cutting wheel by means of a bearing seat, and the goggles include two mirror plates respectively mounted on the rotating shafts;

[0009] The linkage component is connected to the two rotating shafts at the same time, so as to drive the two rotating shafts to drive the mirror plate to deflect and open during cutting.

[0010] In some embodiments, the mirror plates are all L-shaped so as to be respectively attached to the two sides of the main cutting wheel, and the two mirror plates are seamlessly attached after being opened.

[0011] In some embodiments, a mounting seat is provided on the base, and the main body cutting wheel is rotatably disposed on the mounting seat;

[0012] The linkage component includes a traction rope fixed in front of the mounting seat, the other end of the traction rope is Y-shaped and is fixedly wound on two rotating shafts at the same time, and the winding directions of the traction rope on the two rotating shafts are opposite, so as to synchronously drive the two rotating shafts in opposite directions to drive the mirror plate to open;

[0013] A reset member is also arranged on the rotating shaft. When the main cutting wheel is reset after being pressed down, the reset member drives the rotating shaft to drive the mirror plate to reset.

[0014] In some embodiments, the traction rope is made of metal.

[0015] In some embodiments, a limiting ring is provided in front of the main cutting wheel, and the traction rope passes through the limiting ring and is fixedly wound around the rotating shaft.

[0016] In some embodiments, the reset member includes a torsion spring which is respectively sleeved on the rotating shaft and has two ends respectively fixed to the bearing seat and the mirror plate.

[0017] The utility model has at least the following beneficial effects:

[0018] The device is equipped with an automatically deployed goggles system, which can quickly and accurately cover the cutting position during the cutting process, effectively preventing sparks, splashes, dust and other harmful substances from damaging the operator's eyes, thereby significantly improving the safety protection level during the construction process;

[0019] The automatically deployed goggles design avoids the problem of frequent placement and removal of traditional protective covers, reduces the workload of operators, and improves operating efficiency. At the same time, the goggles system has good light transmittance and a wide field of vision, ensuring a clear line of sight for operators during the cutting process, making it easier to place and manipulate materials, thereby enhancing the convenience of operation.

[0020] This allows operators to focus more on the cutting operation itself, reducing stoppages and delays caused by improper operation or insufficient safety protection measures, thereby improving the efficiency of the entire construction process. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] See also Figure 1-5 The utility model provides a technical solution: a material cutting device for civil construction, mainly comprising:

[0030] Base 1: As the stable foundation of the entire device, base 1 is made of high-strength, wear-resistant material to ensure stability during long-term use;

[0031] Main cutting wheel 2: The main cutting wheel 2 is the core part of the device. It is made of high-performance hard alloy material and is precisely processed to ensure a flat and smooth cutting surface.

[0032] Goggles 3: The goggles 3 are composed of two L-shaped mirror plates 31, which are made of transparent polycarbonate material and have anti-fog and anti-scratch functions. Two shafts 5 are installed on the main cutting wheel 2 through the bearing seat. The goggles 3 are rotatably installed on the main cutting wheel 2 through the shafts 5, allowing the mirror plates 31 to rotate flexibly to achieve unfolding and folding. In the initial uncut state, the goggles 3 are folded at the side of the main cutting wheel 2 to save space;

[0033] Linking component 4: The linking component 4 is installed between the goggles 3 and the base 1, and is used to drive the mirror plate 31 of the goggles 3 to automatically rotate and unfold when the main cutting wheel 2 is pressed down for cutting, and automatically and completely cover the cutting position to protect the eyes of the operator.

[0034] In the case where frequent placement and interference are not required, effective cutting protection can be provided through the innovatively designed goggles 3, thereby effectively facilitating safe and efficient cutting and processing of civil construction materials.

[0035] In addition, as an optimization of the device, the following structure is further designed:

[0036] Traction rope 7: The main component of the linkage component 4 is the traction rope 7, one end of which is fixed in front of the mounting seat 6, and the other end is Y-shaped and always in a tight state, and is wound around the two rotating shafts 5 respectively. The winding directions of the traction rope 7 on the two rotating shafts 5 are opposite, ensuring that the two mirror plates 31 can be opened synchronously and in opposite directions. In addition, the traction rope 7 is made of metal to ensure strength and durability;

[0037] In this way, when the main cutting wheel 2 is pressed down, the traction rope 7 is driven to wind around the mounting seat 6, and then the other end of the traction rope 7 is driven to pull the rotating shaft 5 to rotate, so as to stably and automatically drive the goggles 3 to deflect;

[0038] Limiting ring 9: A limiting ring 9 is arranged in front of the main cutting wheel 2. The traction rope 7 passes through the limiting ring 9 and is fixedly wound on the rotating shaft 5. The function of the limiting ring 9 is to limit the moving range of the traction rope 7 to prevent the traction rope 7 from shifting during the moving and cutting process of the main cutting wheel 2, causing it to be unable to be stably wound on the mounting seat 6, thereby ensuring stable drive.

[0039] Resetting member 8: The reset member 8 includes a torsion spring 10 sleeved on the rotating shaft 5, and the two ends of the torsion spring 10 are respectively fixed to the bearing seat and the mirror plate 31. When the main cutting wheel 2 moves downward to drive the mirror plate 31 to deflect, the torsion spring 10 twists and stores force. When resetting, the torsion spring 10 releases the stored energy and drives the rotating shaft 5 to rotate in the opposite direction, so that the mirror plate 31 is reset to the initial folded state.

[0040] Example 2

[0041] Different from the embodiment 1, the mirror plate 31 is made of tempered glass, which is slightly heavier than the mirror plate 31 made of transparent polycarbonate material in the embodiment 1, so that the operation is more laborious, but it has higher transparency and impact resistance.
