Description

Technical Field

[0001] The utility model relates to the technical field of safety helmets, in particular to a safety helmet for railway tunnel construction. Background Art

[0002] A hard hat is a protective device used to prevent head injuries from impacting objects. It consists of a helmet shell, a lining, a chin strap, and a back hoop. When a worker's head is impacted by a falling object, the helmet shell and lining instantly distribute the impact force over the entire skull. The elastic and plastic deformations and allowable structural damage of the helmet's buffer structures absorb most of the impact force, reducing the final impact force on the worker's head to below 4900N, thereby protecting the worker's head. Due to the higher risk associated with railway tunnel construction, existing hard hats for use in railway tunnels do not protect workers' ears and lack safety warning structures, making them easily visible in dark environments. Furthermore, they are not easy to install walkie-talkies. Utility Model Content

To achieve the above-mentioned purpose, the present invention provides a safety helmet for railway tunnel construction, including a cap body 1, wherein the cap body 1 is provided with at least one protrusion 2 for protecting the human ear corresponding to the position of the human ear, the protrusion 2 and the cap body 1 are integrally formed, and the inner side of the protrusion 2 is provided with a receiving groove 3 with an opening facing the back of the head in the direction of the human ear, and an intercom device is provided in the receiving groove 3, and the intercom device is detachably connected to the receiving groove 3. The cap body 1 is integrated with the ear protection structure, and the protrusion 2 is provided at the ear position of the cap body 1, which not only provides ear protection but also increases practicality. The inner side of the protrusion 2 is provided with an opening facing the back of the head The storage groove 3 on the head is used to accommodate the intercom device, so that the intercom device and the storage groove 3 can be quickly disassembled, which is convenient for maintenance and replacement. This design not only protects the worker's ears, but also realizes the convenient integration of communication functions, which can improve the worker's work efficiency and improve the safety performance of the safety helmet; the intercom device is provided with a warning light 5 at the bottom of the storage groove 3, and the other side of the protrusion 2 is provided with a through hole 6 connected to the storage groove 3. The through hole 6 is arranged in a spider web shape. The spider web-shaped through hole 6 is provided, so that the supporting strength of the through hole 6 is not easily reduced. The spider web-shaped structure can reduce the influence of the opening on the strength of the protrusion 2 itself. When the warning light 5 on the intercom 4 is on, the light of the warning light 5 can pass through the spider web The spider-web-shaped through-hole 6 is illuminated, and its spider-web-shaped special pattern is more likely to attract people's attention, thereby improving safety. The use of spider-web-shaped through-holes 6 can reduce manufacturing costs, and sound can also pass through the through-holes 6, which makes it difficult for workers to receive sound signals other than the intercom 4; the intercom device includes an intercom 4 and an elastic positioning part arranged on both side walls of the intercom 4, one end of the elastic positioning part is connected to the intercom device, and the other end is arranged to have a gradually wider distance from the side walls of the intercom 4. The elastic positioning part with one end connected to the intercom device and the other end being arranged to have a gradually wider distance from the side walls of the intercom 4 can make it easier to position the intercom 4 when connected to the accommodating groove 3, and is not likely to cause wear to the intercom 4 itself; the elastic positioning part The positioning portion is an elastic positioning strip 7. The provision of the elastic positioning strip 7 can lower its manufacturing cost and make positioning more convenient. The positioning strip has a longer axial length and can slide a longer distance in the accommodating groove 3. A guide wall 8 is provided in the accommodating groove 3. The width of the guide wall 8 is gradually reduced from the starting end to the end thereof. The guide wall 8 can pressurize the elastic positioning strip 7 and move toward the side walls on both sides of the intercom 4. The provision of the guide wall 8 to guide the intercom 4 into the accommodating groove 3 can prevent the intercom 4 from deviating from the position of the accommodating groove 3. The guide wall 8 with a gradually reduced width from the starting end to the end thereof can cooperate with the elastic positioning strip 7 to apply pressure to the intercom 4 and position it in the accommodating groove 3, making positioning more convenient and stable.The cap body 1 is provided with at least one reflective tape 9. The reflective tape 9 is provided on the cap body 1. When the cap body 1 is exposed to light, the reflective tape 9 can produce a reflective effect to improve safety. When implementing this solution, those skilled in the art can make the protrusion 2 and the safety helmet as one piece, and at the same time open a groove on the side of the protrusion 2 facing the human ear. In this solution, this groove can be used to accommodate the intercom 4, and can also reduce the weight of the cap body 1, reduce the use of materials and reduce the production cost. After the construction workers have put on the safety helmet, they can insert the intercom 4 into the receiving groove 3 from the opening of the receiving groove 3 as needed. At this time, the elastic positioning strips 7 on both sides of the intercom 4 are in contact with the inner walls on both sides of the receiving groove 3, and as the intercom 4 gradually enters the receiving groove 3, the elastic positioning strips 7 will also be squeezed by the guide walls 8 in the receiving groove 3. This pressure is caused by the gradually decreasing width of the guide wall 8 in the receiving groove 3 from the beginning to the end. When the intercom 4 is fully installed in the receiving groove 3, the elastic positioning strip 7 can also be accommodated in the receiving groove 3 and positioned in the receiving groove 3, making it difficult for the intercom 4 to fall out of the receiving groove 3. At this time, the warning light 5 provided on the intercom 4 can shine through the spider-web-shaped through-holes 6, making it easier for construction workers to find it. When the intercom 4 is out of power, the reflective tape provided on the hard hat body 1 can also reflect light when exposed to light to form a warning, which has high safety performance. When it is necessary to remove the intercom 4, it is only necessary to tilt the intercom 4 to one side so that the elastic positioning mechanism on the other side can fall out of the receiving groove 3, then tilt the intercom 4 to the other side so that the elastic positioning mechanism on the other side can also fall out of the receiving groove 3, and finally remove the intercom 4. The structure is simple and the operation is convenient.
