Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1: the utility model provides a prevent high altitude and fall ware, as shown in fig. 1 and fig. 2, contain the concrete built-in fitting 4 of pre-buried 22 wellheads department in the well, safety hook 1 and safety belt 5, fixedly connected with L type mount 6 on the built-in fitting 4, the one end that the built-in fitting 4 was kept away from to mount 6 extends to the top of well 22, be connected with link 7 on the mount 6, go up link 7 and be located well 22 directly over, the both ends of safety hook 1 are equipped with grapple 2 and lower grapple 3 respectively, grapple 3 passes through safety rope 23 and safety hook 1 interconnect down, safety hook 1 is through the mode that last grapple 2 and last link 7 articulate each other and hang with well 22's top with mount 6 interconnect, fixedly connected with on the safety belt 5 hangs lower link 8 with the mutual matching of grapple 3 down. Therefore, when a worker goes up and down the hoistway 22, the worker can wear the safety belt 5 firstly, the lower grapple 3 on the falling protector 1 and the lower hanging ring 8 on the safety belt 5 are hooked with each other, the safety rope 23 can be rolled or released by the falling protector 1 along with the lifting of the worker, when the worker falls carelessly, the lower grapple 3 can rapidly pull the safety rope 23 out of the falling protector 1 under the driving of the lower hanging ring 8, at the moment, the falling protector 1 can be triggered to clamp the safety rope 23 to pull the worker, so that the falling prevention effect is achieved, the possibility that the worker falls down into the well by carelessly losing hands is reduced, and the potential safety hazard in the construction process is reduced; meanwhile, in the process of going up and down the hoistway 22, a worker only needs to hook the lower grapple 3 and the lower hanging ring 8 on the safety belt 5, and the operation is simple.
The implementation principle of the embodiment is as follows: the falling protector 1 is connected with the fixing frame 6 above the hoistway 22 by the worker in the process of going up and down the hoistway 22, and the worker can be pulled by the falling protector 1 to be hung on the fixing frame 6 when falling carelessly, so that the possibility that the worker falls down into the hoistway by carelessly losing his hands is reduced, and the potential safety hazard in the construction process is reduced; the falling protector 1 and the safety belt 5 only need to be connected once, and the falling protector is convenient to connect and simple to operate.
As shown in fig. 3, the fixing frame 6 is further connected with a hook 19 through a reinforcing rope 18, and the length of the reinforcing rope 18 is set as follows: when the lifting hook 19 is hooked with the upper grapple 2 of the falling protector 1, the reinforcing rope 18 is in a loose state. Therefore, when the falling protector 1 normally works, the upper grapple 2 is respectively hooked with the upper hanging ring 7 and the lifting hook 19, when a worker falls carelessly, the upper hanging ring 7 is separated from the fixing frame 6 under the action of impact force, the falling protector 1 can still be connected with the fixing frame 6 through the lifting hook 19 and the reinforcing rope 18, the firmness of connection of the falling protector 1 and the fixing frame 6 is enhanced, and the safety performance is further improved.
As shown in fig. 4, connecting hole 10 has been seted up along vertical direction on the terminal surface that link 7 deviates from to mount 6, connecting hole 10 department is connected with limiting plate 11 through four springs 12, four springs 12 evenly distributed are located connecting hole 10's both sides and limiting plate 11 directly over, connecting rod 9 has set firmly on going up link 7, the tip of connecting rod 9 is equipped with external screw thread 14, connecting rod 9 pegs graft in connecting hole 10 and wear to establish and threaded connection on limiting plate 11 towards limiting plate 11's one end, connecting rod 9's tip still threaded connection has nut 15, nut 15 supports tightly on the terminal surface that limiting plate 11 deviates from mount 6. Consequently, when impact force when the staff falls transmits last link 7 through safety hook 1 on, go up link 7 and can drive connecting rod 9 downstream, limiting plate 11 can make a plurality of springs 12 atress shrink at the downstream of the drive of connecting rod 9, the effect that a plurality of springs 12 set up and have the shock attenuation energy absorption can offset partial impact force, thereby the size of the impact force that last link 7 received has been reduced, it is difficult to continue the possibility that supports safety hook 1 and staff to have reduced to go up link 7 by breaking or warp.
As shown in fig. 4, an annular rubber pad 13 is adhered to the inner wall of the connecting hole 10 along the periphery, and when the connecting rod 9 is inserted into the connecting hole 10, the rubber pad 13 contacts with the outer periphery of the connecting rod 9. The rubber pad 13 is arranged to achieve the effect of isolating the connecting rod 9 and the fixing frame 6 from each other, so that the connecting rod 9 is difficult to directly support the inner wall of the connecting hole 10, and the possibility that the connecting rod 9 is bent and deformed by itself due to transverse moving impact on the inner wall of the connecting hole 10 under the driving of the falling protector 1 when workers fall carelessly is reduced, and the connection strength between the hanging ring 7 and the fixing frame 6 is affected.
As shown in fig. 4 and 5, the end of the connecting rod 9 extending out of the nut 15 is provided with a reinforcing hole 16, and a limiting bolt 17 penetrates through the reinforcing hole 16. Therefore, when the nut 15 is loosened and moves to the reinforcing hole 16 in the direction away from the limiting plate 11, the nut 15 is blocked by the limiting bolt 17 and is difficult to separate from the connecting rod 9, the limiting bolt 17 has a limiting effect on the nut 15, the possibility that the firmness of connection between the upper hanging ring 7 and the fixed frame 6 is reduced due to the fact that the nut 15 is loosened and separated from the connecting rod 9 is reduced, and the firmness of connection between the upper hanging ring 7 and the fixed frame 6 is further improved; simultaneously, staff's accessible bolt dismantlement's mode is in proper order lifted off limit bolt 17, nut 15 and connecting rod 9, then lift off last link 7 from mount 6 to the staff can change last link 7 of deformation or damage.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
