Description

Technical Field

[0002] Safety fall prevention net is a kind of labor protection equipment to prevent falls. It is mostly used in various high-altitude operations to prevent workers or objects from falling from heights, reducing or avoiding the injuries and losses caused by them.

[0003] The safety anti-fall net in the existing technology is usually composed of steel pipes and woven mesh. Multiple steel pipes are spliced ​​into a rectangle, and the woven mesh is wrapped around the steel pipe to form an installed anti-fall net.

[0037] like Figure 7-Figure 8As shown, the fitting mechanism includes a sliding plate 601, a sliding plate 601 is slidably connected in the guide rail 401, a fourth elastic member is provided between the sliding plate 601 and the slide seat 402, the fourth elastic member is a tension spring, an elastic extension shaft 602 is fixedly connected in the guide frame 301, the telescopic end of the elastic extension shaft 602 is fixedly connected to the rectangular frame 603, one side of the rectangular frame 603 is connected to a driving assembly, the driving assembly consists of a guide wheel and a pull rope, wherein the guide wheel is rotatably connected to one side of the guide rail 401, one end of the pull rope is fixedly connected to the sliding plate 601, the other end of the pull rope slides through the guide rail 401 and is wound around the guide wheel, and is fixedly connected to the rectangular frame 603, four evenly distributed sliders 604 are slidably connected in the guide frame 301, the four sliders 604 are symmetrically distributed about the elastic extension shaft 602, and the four sliding One side of the block 604 is fixedly connected with an elastic extension rod 605, and the outer wall sliding sleeve of the elastic extension rod 605 is provided with a push ring 606, and the outer wall of the fixed end of the elastic extension rod 605 is provided with a sliding groove, and the outer wall of the telescopic end of the elastic extension rod 605 is fixedly connected with a vertical shaft 607 used in conjunction with the push ring 606, and the vertical shaft 607 is stuck in the sliding groove of the elastic extension rod 605 and slides in the sliding groove, and the outer sliding sleeve of the push ring 606 is provided with a sliding frame 608, and a fifth elastic member is provided between the sliding frame 608 and the push ring 606, and the fifth elastic member is a tension spring. The sliding frame 608 is slidably connected to the rectangular frame 603 and is slidably connected to the outer wall of the fixed end of the elastic extension rod 605. A guide rod 609 is symmetrically fixedly connected inside the sliding frame 608, and the guide rod 609 is slidably connected to the push ring 606.

[0038] like Figure 7 and Figure 9 As shown, one side of the first bracket 201 is hinged to one end of the elastic universal telescopic shaft 701, and the other end of the elastic universal telescopic shaft 701 is hinged to the second bracket 202. The two elastic universal telescopic shafts 701 are distributed in an "eight" shape, and the telescopic ends of the four elastic extension rods 605 are all hinged to one end of the universal shaft 801, and the other ends of the four universal shafts 801 are respectively hinged to the corresponding first bracket 201 and second bracket 202.

[0039] Initially, the first bracket 201 and the second bracket 202 are in a vertical state, the first magnet on the shift block 309 and the second magnet on the support tube 302 attract each other, and the lap plate 503 is overlapped on the adjacent clamping shaft 504. The lap plate 503 cooperates with the clamping shaft 504 to make the first bracket 201 and the adjacent second bracket 202 in the same vertical line. First, the protective mechanism is hoisted to the cantilever beam of the outer wall of the building through the hoisting equipment, and then the staff determines whether the switching mechanism needs to be adjusted according to the shape of the outer wall of the building. There are two specific cases. The first case is that the outer wall of the building is a vertical surface and there is no need to adjust the switching mechanism. After the protective mechanism is hoisted to the cantilever beam, the staff pulls the handle on the swing rod 304 to adjust the protective mechanism. The position of the guard mechanism is adjusted. When the handle is pulled to the right, the handle drives the swing rod 304 to rotate with the connection point of the rotating shaft as the center of the circle. The swing rod 304 drives the vertical rod thereon to squeeze the outer wall of the T-shaped frame 305, causing the T-shaped frame 305 to move to the right. The T-shaped frame 305 drives the two guide shafts 303 to rotate counterclockwise through the two first telescopic rods 306. During this process, the first telescopic rod 306 extends, and the walking wheel drives the T-shaped shaft 3031 to rotate in any direction with the connection point of the guide shaft 303 as the center of the circle. Then the outer wall of the first telescopic rod 306 contacts and squeezes the inner wall of the first fan-shaped groove of the support tube 302, thereby causing the guard mechanism as a whole to start to move to the right. During the movement of the guard mechanism, the contact wheel 203 on the hinge chain 1 starts to move to the right. Finally, it maintains contact with the outer wall of the building. After moving to the appropriate position, the staff will push the two first brackets 201 and the two second brackets 202. The two first brackets 201 and the two second brackets 202 rotate with the connection point of the hinge chain 1 as the center of the circle, so that the two first brackets 201 and the two second brackets 202 rotate to the side close to the guide frame 301 and are in an inclined state. During this process, the two first brackets 201 drive the universal telescopic rod 405 thereon to move obliquely downward, and the disc 406 drives the connecting block 404 to rotate through the second elastic member. Since the elastic force of the second elastic member is large, the second elastic member will not be twisted, so that the two universal telescopic rods 405 remain in a relative state, and the connecting block 404 squeezes the slide 402 through the support rod 403. , the slide 402 is forced to drive the limit pin 407 to slide backward, and the first elastic member is forced to shrink until the limit pin 407 is aligned with the lock hole of the guide rail 401. The limit pin 407 falls and slides into the lock hole under the influence of its own weight, limiting the slide 402 so that the first bracket 201 and the second bracket 202 remain in an inclined state. During this process, the slide 402 pulls the sliding plate 601 to slide backward through the fourth elastic member, and the sliding plate 601 drives the rectangular frame 603 to slide forward through the pull rope in the drive assembly. The rectangular frame 603 drives the telescopic end of the elastic extension shaft 602 to extend, and drives the four sliding frames 608 thereon to move to the side close to the first bracket 201. The sliding frame 608 applies tension to the push ring 606 through the fifth elastic member.The push ring 606 is forced to slide forward along the outer wall of the elastic extension rod 605 and squeeze the vertical shaft 607. At this time, several contact wheels 203 have already contacted the outer wall of the building, and the first bracket 201 and the second bracket 202 cannot move, so that the universal shaft 801 and the telescopic end of the elastic extension rod 605 cannot move. The push ring 606 cannot drive the telescopic end of the elastic extension rod 605 to extend through the vertical shaft 607. The telescopic end of the elastic extension rod 605 remains stable. Then the sliding frame 608 continues to move and the distance between it and the corresponding push ring 606 increases. The fifth elastic member continues to be forced to extend until the limit pin 407 is stuck in the lock hole of the guide rail 401. At this time, the protective mechanism as a whole remains stable. Then the staff uses steel cables to fix the top ends of the first bracket 201 and the second bracket 202 to the outer wall of the building, thereby completing the deployment of the protective mechanism when the outer wall of the building is vertical.

[0040] The second situation is that the outer wall of the building is curved. At this time, the switching mechanism needs to be adjusted to make the two first brackets 201 and the two second brackets 202 movable. The staff rotates the two lap plates 503 upward. After the lap plates 503 are rotated upward, they disengage from the corresponding card shaft 504, allowing the connecting ring 502 to move. The third elastic member is released to drive the connecting ring 502 to slide to the side away from the first bracket 201. The connecting ring 502 drives the lap plates 503 away from the corresponding card shaft 504, and then moves the shift block 309 downward. After the shift block 309 moves, the first magnet on it is away from the second magnet, and drives the corresponding directional sleeve 307 to slide downward. Then the two directional pins 308 are respectively inserted into the two positioning holes of the directional sleeve 307, and then the handle on the swing rod 304 is pulled to adjust the position of the protective mechanism. When it is pulled to the right, When the handle is turned, the handle drives the swing rod 304 to rotate with the connection of the rotating shaft as the center of the circle, causing the two guide shafts 303 to rotate counterclockwise and the entire protective mechanism to move to the right. At this time, the walking wheel drives the corresponding T-shaped shaft 3031 to rotate with the connection of the guide shaft 303 as the center of the circle, and the T-shaped shaft 3031 drives the directional sleeve 307 to rotate through the two directional pins 308 thereon, and the directional sleeve 307 drives the shift block 309 to rotate, and then the shift block 309 contacts one end of the second fan-shaped groove of the support tube 302, thereby limiting the rotation angle of the T-shaped shaft 3031. At this time, an angle is formed between the walking wheel and the building wall. During the process of the protective mechanism moving to the right as a whole, the protective mechanism moves obliquely toward the building wall as a whole, so that the several contact wheels 203 on the hinge chain 1 always keep in contact with the outer wall of the building, effectively preventing the protective mechanism from falling from the cantilever beam;During the movement of the protective mechanism, the hinge chain 1 drives the bottom ends of the two first brackets 201 and the two second brackets 202 to move displacedly along the curved surface of the outer wall of the building. The two first brackets 201 and the two second brackets 202 respectively drive the four elastic extension rods 605 to perform different degrees of dynamic extension and contraction through the corresponding universal shafts 801. When they move to the appropriate position, the staff pushes the two first brackets 201 and the two second brackets 202, so that the two first brackets 201 and the two second brackets 202 are in an inclined state, and the limit pin 407 is locked in the lock hole to limit the slide 402. During this process, the slide 402 pulls the sliding plate 601 to slide backward through the fourth elastic member, and the sliding plate 601 drives the rectangular frame 603 to slide forward through the pull rope in the drive assembly, so that the telescopic ends of the four elastic extension rods 605 are extended. At this time, several contact wheels 203 have contacted the outer wall of the building, and the first bracket 201 and the second bracket 202 cannot move. Then the sliding frame 608 continues to move 406 and the corresponding push ring 606. The fifth elastic member is continuously extended under force until the limit pin 407 is stuck in the lock hole of the guide rail 401. At this time, the top ends of the two first brackets 201 and the two second brackets 202 are close to or away from each other, and the telescopic end of the elastic universal telescopic shaft 701 is forced to contract or extend, thereby supporting the bottom end of the second bracket 202 to prevent the bottom end of the second bracket 202 from failing to fit the outer wall of the building. When the two first brackets 201 are misaligned, the two first brackets 201 swing toward or away from the side of the connecting block 404, causing the universal telescopic rod 405 on them to swing and extend or contract, and a relative rotational dislocation is generated between the universal telescopic rod 405 and the connecting block 404, causing the disc 406 and the connecting block 404 to rotate relative to each other. At this time, the connecting block 404 is restricted by the support rod 403 and cannot move, causing the second elastic member between the disc 406 and the connecting block 404 to be twisted under force, thereby completing the deployment of the protective mechanism when the outer wall of the building is curved. ;

[0041] like Figure 10 As shown, it also includes an unlocking plate 901. The bottom of the guide frame 301 is hinged with the unlocking plate 901 through a vertical plate. The outer wall of the guide rail 401 is slidably connected to the unlocking frame 902. The unlocking frame 902 is fixedly connected with a horizontal axis used in conjunction with the unlocking plate 901. The limit pin 407 is symmetrically fixed with a convex axis used in conjunction with the unlocking frame 902. The staff steps on the unlocking plate 901 to squeeze the unlocking frame 902 on the convex axis, so that the limit pin 407 disengages from the lock hole of the guide rail 401.

[0042] like Figure 9 、 Figure 11-12As shown, it also includes a wedge block 1001, wherein one side of one second bracket 202 is symmetrically fixedly connected with the wedge block 1001, and one side of the other second bracket 202 is symmetrically fixedly connected with the card box 1002, and an elastic limit block 1003 is slidably connected in the card box 1002, and the elastic limit block 1003 is used in conjunction with the wedge block 1001, and one side of the card box 1002 is slidably connected with an unlocking rod 1004, and an inclined groove is provided in the unlocking rod 1004, and one side of the elastic limit block 1003 is fixedly connected with a sliding shaft 1005, and one end of the sliding shaft 1005 slides through the card box 1002 and is used in conjunction with the inclined groove. When the unlocking rod 1004 is pulled downward, the unlocking rod 1004 squeezes the outer wall of the sliding shaft 1005 through the inclined groove therein, causing the elastic limit block 1003 to shrink and slide.

[0043] After the protective mechanism is unfolded, several protective mechanisms need to be spliced ​​together. The number of spliced ​​protective mechanisms can be flexibly adjusted according to the needs of the construction site. When the outer wall of the building is vertical, the guide frame 301 in one unfolded protective mechanism is first fixed to the outer wall of the building by bolts, and the staff moves the other unfolded protective mechanism closer to the fixed protective mechanism. Then the wedge block 1001 enters the corresponding card box 1002 and contacts and squeezes the elastic limit block 1003 therein. The elastic limit block 1001 is fixed to the outer wall of the building by bolts. 003 shrinks and slides under the force, and drives the sliding shaft 1005 to squeeze the inclined groove of the unlocking rod 1004. The unlocking rod 1004 slides downward under the force, and then the wedge block 1001 passes over the elastic limit block 1003. The elastic limit block 1003 releases and slides to limit the wedge block 1001. The elastic limit block 1003 drives the sliding shaft 1005 to reset. The inclined groove of the unlocking rod 1004 is no longer squeezed by the sliding shaft 1005, so that the unlocking rod 1004 slides and resets, thereby completing the splicing of the two protective mechanisms.

[0044] When the outer wall of the building is curved, the guide frame 301 in one of the deployed protective mechanisms is first fixed to the outer wall of the building by bolts, and then the staff moves the other deployed protective mechanism closer to the fixed protective mechanism. At this time, an angle is formed between the running wheel and the building wall. During the overall movement of the protective mechanism to the right, the several contact wheels 203 on the hinge chain 1 always keep in contact with the outer wall of the building. The hinge chain 1 rotates with the curved surface of the building wall, causing the bottom ends of the two first brackets 201 and the two second brackets 202 to move in an offset manner. The two first brackets 201 and the two second brackets 202 respectively drive the corresponding universal shafts 801 to move the elastic extension rods 60 5 is squeezed, and the telescopic end of the elastic extension rod 605 drives the vertical shaft 607 to squeeze or move away from the adjacent push ring 606. The push ring 606 slides on the outer wall of the corresponding elastic extension rod 605 through the action of the vertical shaft 607 or the fifth elastic member. When the mobile protective mechanism is about to fit into the fixed protective mechanism, the rotation angle of the second bracket 202 of the mobile protective mechanism and the second bracket 202 of the fixed protective mechanism tend to be consistent, so that the wedge block 1001 of the mobile protective mechanism enters the card box 1002 corresponding to the fixed protective mechanism, and the wedge block 1001 is limited by the elastic limit block 1003, thereby completing the splicing of the two protective mechanisms.

[0045] When the protective mechanism needs to be removed, the staff first pulls the unlocking rod 1004 downwards, and the unlocking rod 1004 squeezes the sliding shaft 1005 through the inclined groove therein. The sliding shaft 1005 is forced to drive the elastic limit block 1003 to shrink and slide. After the elastic limit block 1003 shrinks and slides, it no longer contacts the wedge block 1001. After the wedge block 1001 is freed from the restriction, the second bracket 202 can move. Then the staff steps on the unlocking plate 901, and the unlocking plate 901 is forced to rotate with the connection point of the vertical plate as the center of the circle, and the unlocking plate 901 is unlocked. The horizontal axis in the frame 902 is squeezed, and the horizontal axis is forced to drive the unlocking frame 902 to lift and slide upward, so that the unlocking frame 902 squeezes the convex axis on the limit pin 407, and the convex axis is forced to drive the limit pin 407 to slide upward, so that the limit pin 407 is disengaged from the lock hole of the guide rail 401, so that the slide 402 can move. The first elastic member is released and drives the slide 402 to slide and reset. The slide 402 drives the connecting block 404 to squeeze the telescopic ends of the two universal telescopic rods 405 through the support rod 403. The second elastic member is released and reset and presses the two ends through the disc 406. The universal telescopic rod 405 provides a supporting force to rotate and reset the two first brackets 201. When the slide 402 is reset, the fourth elastic member is no longer pulled, so that the sliding plate 601 can move. The sliding plate 601 no longer pulls the rectangular frame 603 through the pull rope in the drive assembly. The telescopic end of the elastic extension shaft 602 contracts and drives the rectangular frame 603 to reset. The rectangular frame 603 drives the four sliding frames 608 thereon to move and reset. The sliding frame 608 drives the push ring 606 to slide and reset through the fifth elastic member, and the vertical shaft 607 is separated from the push ring 606. 06 allows the telescopic end of the elastic extension rod 605 to move, and the telescopic end of the elastic extension rod 605 contracts and resets, and drives the bottom end of the first bracket 201 or the second bracket 202 to reset through the universal shaft 801. Then the staff presses the connecting ring 502 to contract the third elastic member, and the connecting ring 502 drives the lap plate 503 to move to the side close to the second bracket 202, and then rotates the lap plate 503 so that the notch of the lap plate 503 overlaps the clamping shaft 504, thereby completing the overall reset of the protective mechanism.
