Description

Technical Field

[0002] After the high-rise steel structure, especially the I-beam, is hoisted, it is usually necessary to cut off the lifting lugs to ensure the safety and stability of the steel structure. Specifically, the operator needs to accurately locate the position and number of the lifting lugs to ensure that they are completely cut off. Then, it is necessary to equip appropriate tools and equipment, such as cutting machines, cutting torches, etc., and wear safety equipment such as welding protective clothing. After the cutting is completed, it is necessary to clean up the work area in time, remove the cut lifting lugs and the generated waste, and keep the work area clean. However, at this stage, when the staff are performing the cutting operation, the sparks are difficult to control. The staff need to hold a protective mask to prevent spark splashing. Although the use of a protective mask can reduce the direct contact of the sparks to a certain extent, it cannot completely eliminate the splashing of sparks, especially at the construction site of high-rise steel structures. There are often factors such as wind and air flow, which may cause sparks to splash over a long distance. Even with a mask, it is still impossible to completely block the sparks from invading the face and eyes. Wearing a bulky mask will also affect the clarity of vision and the flexibility of operation, affecting the efficiency and accuracy of the lifting lug cutting. Utility Model Content

DETAILED DESCRIPTION

[0017] 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. 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.

[0018] See also Figure 1-5 The utility model provides an embodiment: a spark splash prevention device for cutting off the lifting lug of a high-rise steel structure, comprising a fire receiving bucket 1 and a clamping groove 2 arranged on the outer wall of one side of the fire receiving bucket 1, a supporting edge 3 is arranged below the clamping groove 2, the fire receiving bucket 1 is clamped with the flange of the I-shaped steel beam through the clamping groove 2, a front shielding part 5 is integrally formed on the outer wall of one side of the fire receiving bucket 1, and a cavity 6 is arranged inside the fire receiving bucket 1 on one side of the front shielding part 5, the fire receiving bucket 1 and the front shielding part 5 can effectively prevent sparks from splashing around and in the direction of users, and ensure the safety of workers and high-rise construction facilities;

[0019] A handle 4 is welded to the top of the fire receiving bucket 1. The fire receiving bucket 1 is made of a stainless steel component. By welding a handle to the top of the fire receiving bucket 1, the operator can carry and move the spark anti-splash device more easily. The spark anti-splash device component made of stainless steel has good corrosion resistance, especially in steel structure construction, which may be affected by environmental factors such as rain and humidity. Stainless steel can effectively resist corrosion, extend the service life of the spark anti-splash device, and reduce the frequency of maintenance and replacement.

[0020] Two symmetrical circular transverse ribs 8 are fixed to one end of the interior of the fire receiving bucket 1, and elastic support structures are arranged inside the two circular transverse ribs 8. A pressing plate 9 is installed at the movable end of the elastic support structure. The upper surface of the pressing plate 9 contacts the lower surface of the flange of the I-shaped steel beam. A T-shaped pressing arm 10 is fixed to the back of the pressing plate 9. One end of the T-shaped pressing arm 10 penetrates the outside of the fire receiving bucket 1. A sliding groove 7 for the T-shaped pressing arm 10 to slide up and down is arranged on the back of the fire receiving bucket 1.

[0021] When the slot 2 is connected with the flange of the I-beam, the staff can manually press down the T-shaped pressure arm 10, so that the T-shaped pressure arm 10 drives the pressure plate 9 downward. At this time, the elastic support structure in the circular cross rib 8 is in a compressed state, and a space is reserved above the pressure plate 9 for the flange of the I-beam to enter. When the flange of the I-beam is inserted into the space, the staff manually releases the T-shaped pressure arm 10, and the pressure plate 9 is firmly pressed on the bottom end of the flange of the I-beam, thereby ensuring the installation stability of the device and the I-beam. Long-term wearing of a pressure hand-held protective mask will cause fatigue and discomfort to the neck, shoulders and face of the operator, while the use of the spark anti-splash device does not require the operator to wear a heavy mask for a long time, which can reduce their physical burden and improve work comfort.

[0022] A plurality of rubber columns 901 are inlaid on the top of the pressing plate 9, and a guide column 902 is fixed on the bottom of the pressing plate 9. The bottom end of the guide column 902 extends to the inside of the round-shaped transverse rib 8. When the pressing plate 9 contacts the bottom end of the flange of the I-shaped steel beam, the rubber column 901 protects the flange of the I-shaped steel beam.

[0023] The elastic support structure includes a sliding pin 801 fixed inside the circular cross rib 8, and a limit spring 802 installed on the top of the sliding pin 801. The top of the limit spring 802 passes through the outside of the circular cross rib 8 and is fixedly connected to the bottom end of the pressure plate 9. The sliding pin 801 forces the limit spring 802 and the pressure plate 9 to always move upward, thereby improving the connection stability between the pressure plate 9 and the flange of the I-beam steel beam. In high-altitude operations and steel structure construction, equipment and facilities are often faced with various challenges and dangers, such as wind, rain, collisions with objects, etc., which can easily cause damage or wear to the equipment. Through the elastic support structure, the pressure plate 9 and other components, the stability and durability of the spark protection device can be effectively increased.

[0024] When the embodiment of the present application is in use, the staff first takes out the fire receiving bucket 1 in the spark prevention device, so that the fire receiving bucket 1 is stuck on the flange of the I-shaped steel beam through the slot 2, so that the cavity 6 formed in the upper part of the fire receiving bucket 1 is used to shield and protect the ear to be cut, and the front shielding part 5 is facing the staff. When the staff uses a cutting machine, a cutting torch and other equipment to cut the ear, the fire receiving bucket 1 and the front shielding part 5 can effectively prevent sparks from splashing around and in the direction of the user, thereby ensuring the safety of the workers and high-rise construction facilities. The use of the device will not have much impact on the operator's field of vision and flexibility, so the personnel can concentrate more on the operation, reduce the occurrence of engineering errors and mistakes, and improve the construction quality and safety.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
