Description

Technical Field

[0001] The present application relates to the field of metal roof construction, and in particular to a safety device for light steel roofs. Background Art

[0002] Metal roofs have the advantages of strong durability, good waterproofness, easy installation, environmental protection and energy saving, and beautiful appearance. They are widely used in modern buildings. Metal roofs are mostly light steel vertical lock seam roofs. The vertical lock seam roof system does not require maintenance, but it does require regular inspections, especially after snowstorms, the roof and gutters must be cleaned in time.

[0003] The lifeline safety device is a system that provides continuous fall protection for high-altitude mobile and fixed-point operations. For various installation, maintenance, repair and cleaning tasks, it can provide perfect safety protection for operations at high altitudes and edges, such as large roofs such as airport roofs, stadiums, public utility buildings, workshops, etc.

[0004] So far, most lifeline safety devices use horizontal lifelines, which have many installation components and require 3-4 people to connect the fixed base to the roof, and then set up cables for movement between the fixed bases. The installation efficiency is low and the installation is relatively cumbersome. Utility Model Content

[0005] The purpose of this application is to solve the problem that most of the lifeline safety devices proposed in the above background technology adopt horizontal lifelines, which have many installation components and require 3-4 people to cooperate to fix the fixed base and the roof, and then set up cables for movement between the fixed bases, resulting in low installation efficiency and complicated installation. This application provides a safety device for light steel roofs.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A safety device for a light steel roof comprises two support rods, a connecting plate is provided between the two support rods, an engaging fixing mechanism is provided between the two support rods, a fall arrester is provided on the connecting plate, and a buffer protection mechanism is provided between the connecting plate and the fall arrester.

[0008] By adopting the above technical solution, the spacing between the two support rods is adjusted using the bite fixing mechanism so that the two support rods correspond to the upright lock seams on the light steel roof. Then, the bite fixing mechanism is directly engaged with the upright lock seams to fix the two support rods on the light steel roof. Then, the buffer protection mechanism is installed on the connecting plate. Then, the fall arrester is installed on the buffer protection mechanism. Then, the cable end of the fall arrester is connected to the safety belt of the construction worker, thereby facilitating the fixed installation of the entire safety device and the light steel roof. At the same time, the spacing of the support rods can be adjusted according to the size of the upright lock seams on the single metal plate of the roof, so as to facilitate the use of light steel roofs of different sizes.

[0009] Furthermore, the bite fixing mechanism includes two bite blocks 1 symmetrically arranged between two support rods, the two bite blocks 1 are fixedly connected to the corresponding support rods, a bite block 2 is arranged on one side of the bite block 1, a moving component is arranged between the bite block 1 and the bite block 2, and an adjustment component is arranged between the two support rods.

[0010] By adopting the above technical solution, the spacing between the two support rods is adjusted using the adjustment component, so that the bite block 1 on the two support rods is in contact with the upright lock edge of the roof, and then the movable component is used to drive the bite block 2, so that the bite block 1 and the bite block 2 are engaged with the upright lock edge of the roof, thereby facilitating the fixed installation of the entire safety device and the light steel roof. At the same time, the spacing of the support rods can be adjusted according to the size of the upright lock edge on the single metal plate of the roof, which is convenient for the use of light steel roofs of different sizes.

[0011] Furthermore, the movable component includes a movable threaded rod rotatably connected to the bite block one, the movable threaded rod passes through the bite block two and is threadedly connected to the bite block two, and two symmetrical limiting slide rods are fixed on the bite block one, the limiting slide rods pass through the bite block two and are slidably connected to the bite block two.

[0012] By adopting the above technical solution, the movable threaded rod is rotated on the bite block 1, and under the drive of the movable threaded rod and the support of the limiting slide rod, the bite block 2 is moved toward the bite block 1, so that the bite block 1 and the bite block 2 can be easily contacted with the upright lock edge on the roof.

[0013] Furthermore, a limiting block is fixed to one end of the limiting sliding rod away from the first bite block, and the limiting block corresponds to the second bite block.

[0014] By adopting the above technical solution, when the bite block 2 slides on the limit slide rod, the limit block blocks the bite block 2, thereby reducing the possibility of the bite block 2 falling off the movable threaded rod.

[0015] Furthermore, the adjustment assembly includes an adjustment rod 1 arranged between two support rods, an adjustment rod 2 is arranged on the adjustment rod 1, the middle part of the adjustment rod 1 is rotatably connected to the middle part of the adjustment rod 2, and the connecting plate is rotatably connected to the adjustment rod 1.

[0017] Furthermore, both ends of the adjusting rod 1 and the adjusting rod 2 are slidably connected with fixing bolts, and both ends of the two support rods are provided with a plurality of adjustment holes, the adjustment holes correspond to the fixing bolts, and the fixing bolts pass through the adjustment holes and are threadedly connected to the support rods.

[0018] By adopting the above technical solution, after the adjusting rod 1 and the adjusting rod 2 are rotated, the fixing bolts at the ends of the adjusting rod 1 and the adjusting rod 2 are threadedly connected with the corresponding adjusting holes on the support rod, so that the adjusting rod 1 and the adjusting rod 2 can be easily fixed.

[0020] By adopting the above technical solution, the cable of the fall arrester is used to protect the user. When a fall accident occurs, the fall arrester directly locks the cable, and the energy absorber buffers the generated downward force. Therefore, when a fall accident occurs and the fall arrester locks the cable, the energy absorber can be used to reduce the impact of the downward force on the support rod, thereby improving the stability of the fixation on the light steel roof.

[0021] Furthermore, a buffer belt is fixed to the cable end of the fall arrester.

[0022] By adopting the above technical solution, the buffer zone is connected to the construction workers' safety belt. When a fall occurs, the buffer zone plays a buffering role, thereby further reducing the impact force caused by the fall.

[0023] After fixing the support rod to the light steel roof, hang one end of the energy absorber on the buckle rod on the connecting plate with a shackle, then connect the shackle at the other end of the energy absorber to the fall arrester, and finally fix the buffer belt on the cable end of the fall arrester. Then connect the buffer belt to the construction worker's safety belt, and use the cable of the fall arrester cable to protect the user. In the event of a fall accident, the fall arrester directly locks the cable, and the energy absorber and the buffer belt buffer the impact caused by the fall. By using the energy absorber to connect the fall arrester to the connecting plate and fixing the buffer belt on the cable end of the fall arrester, when a fall accident occurs and the fall arrester locks the cable, the energy absorber and the buffer belt can be used to reduce the impact of the falling force on the support rod, thereby improving the stability of the fixation on the light steel roof.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] The first and second adjusting rods are used to adjust the spacing of the support rods according to the size of the vertical locking edges on the single metal plate of the roof, so as to facilitate the use of light steel roofs of different sizes.

[0026] 2. In the present application, after the support rod is fixed to the light steel roof, one end of the energy absorber is hung on the buckle rod on the connecting plate by using a shackle, and then the shackle at the other end of the energy absorber is connected to the fall arrester, and finally a buffer belt is fixed to the cable end of the fall arrester, and then the buffer belt is connected to the construction worker's safety belt, and the cable of the fall arrester cable is used to protect the user. In the event of a fall accident, the fall arrester directly locks the cable, and at the same time, the energy absorber and the buffer belt cushion the impact caused by the fall, so that when a fall accident occurs and the fall arrester locks the cable, the energy absorber and the buffer belt can be used to reduce the impact of the falling force on the support rod, thereby improving the stability of the fixation on the light steel roof.
