Description

Technical Field

[0001] The present invention relates to the field of hanging devices, and particularly to a safety rope hanging device for tiling on an inclined roof and a using method thereof. Background Art

[0002] Building roofs include various types, among which flat roofs and inclined roofs are relatively common. When building an inclined roof, tiles are usually laid on the inclined roof to achieve an aesthetic or waterproof effect; when laying tiles on an inclined roof, construction workers need to stand on the inclined roof to carry out tile laying operations. However, the inclined roof may cause the situation that people cannot stand steadily. Therefore, in order to enable people to stand more stably on the inclined roof, a hanging device is provided on the inclined roof.

[0003] To ensure the safety of personnel during operation, when a person stands at the lowest point of the inclined roof, the rope needs to be in a tensioned state to reduce the possibility of the person falling. However, with a fixed length of the rope in the existing hanging device, the walking range of the person is within a sector with the hanging ring as the center and the rope length as the radius. However, the horizontal length of the roof ridge may be greater than the length of the rope. Therefore, a plurality of hanging rings need to be arranged along the horizontal direction of the roof ridge; thus, when laying tiles at different positions, the person needs to hang the rope on different hanging rings to meet the laying range. However, this method requires the person to hang the safety rope from one hanging ring to another, which may lead to a more complicated operation process.

[0004] Therefore, it is necessary to provide a new safety rope hanging device for tiling on an inclined roof and a using method thereof to solve the above technical problems. Summary of the Invention

[0032] Preferably, in the step S4, the number of turns of the second suspension rope wound around the surface of the roller shaft is at least 2 turns.

[0033] Compared with the related art, the safety rope hanging device for inclined roof tile hanging and its using method provided by the present invention have the following beneficial effects:

[0034] 1. The present invention uses two snap rings to hang one end of the second suspension rope on the outer surface of the first suspension rope, so that the two snap rings can slide on the surface of the first suspension rope. Pass the second suspension rope through the connecting ring and fix the end of the second suspension rope through the rope pressing component. The rotation of the connecting ring is convenient for personnel to turn, increasing the flexibility of use. At the same time, it can also limit the second suspension rope from moving actively close to the box cover to prevent accidental opening of the box cover and avoid safety risks.

[0035] 2. The present invention passes the end of the second suspension rope through the connecting ring and winds it around the roller shaft, and then uses the rope pressing component to clamp the end of the second suspension rope. The number of turns of the second suspension rope wound around the surface of the roller shaft is at least 2 turns. When the self - locking mechanism locks the bidirectional rotation direction of the roller shaft, the roller shaft cannot rotate. Winding the second suspension rope at least 2 turns on the surface of the roller shaft can avoid the situation of the second suspension rope sliding on the surface of the roller shaft. In addition, cooperating with the rope pressing component to clamp the end of the second suspension rope ensures stable and reliable connection and can bear the expected load. Using the double restrictions of the rotation limit of the roller shaft and the rope pressing component to limit the second suspension rope from coming off during construction ensures the safety of construction operations.

[0036] 3. The present invention sets a sliding seat in the fixed box and cooperates with the pressing block on the box cover. The pressing block can move the sliding seat towards the fixed column side, and then use the ejector pin to squeeze and fix the second suspension rope on the surface of the friction surface of the two fixed columns, achieving an effective limiting effect on the second suspension rope in the fixed box. Furthermore, one end of the second suspension rope can be released, improving the safety of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Example 1

[0056] In the specific implementation process, as Figure 1As shown in the figure, on the one hand, the safety rope hanging device for inclined roof tile hanging provided by the present invention includes installation piles fixedly installed at both ends of the inclined roof and a hanging component. A first hanging rope 1 is connected between the two installation piles. A second hanging rope 2 that slides on its surface is provided on the outer surface of the hanging rope. The hanging component is slidably installed on the outer surface of the second hanging rope 2;

[0057] Reference Figures 2 - 6 As shown in the figure, the hanging component includes a support plate 3, a connecting head 4, a connecting ring 5, a roller shaft 6 and a rope pressing component. A safety belt 7 for binding the body is provided on one side of the support plate 3. One end of the connecting head 4 is fixedly installed at one end of the support plate 3. The connecting ring 5 is rotatably installed in the connecting head 4, and the connecting ring 5 is sleeved on the outer surface of the second hanging rope 2. Two opposite connecting plates 8 are fixed on one side of the connecting ring 5. A roller shaft 6 is rotatably installed between the two connecting plates 8. Self-locking mechanisms that perform one-way intermittent movement are provided at both ends of the roller shaft 6. The two self-locking mechanisms are arranged in the opposite direction. The end of the second hanging rope 2 passes through the connecting ring 5, the roller shaft 6 and the rope pressing component in sequence. The rope pressing component is fixedly installed on one side of the support plate 3;

[0058] The rotation of the connecting ring 5 is convenient for personnel to turn, increasing the flexibility of use;

[0059] It should be noted that the end of the second hanging rope 2 is passed through the connecting ring 5 and wound around the roller shaft 6, and then the end of the second hanging rope 2 is clamped by the rope pressing component. The number of turns of the second hanging rope 2 wound around the surface of the roller shaft 6 is at least 2 turns. When the self-locking mechanism locks the two-way rotation direction of the roller shaft 6, the roller shaft 6 cannot rotate, so that at least 2 turns of the second hanging rope 2 wound around the surface of the roller shaft 6 can avoid the situation that the second hanging rope 2 slides on the surface of the roller shaft 6. In addition, the end of the second hanging rope 2 is clamped by the rope pressing component to ensure firm and reliable connection and be able to withstand the expected load.

[0060] Reference Figure 7 As shown in the figure, the self-locking mechanism includes a ratchet wheel 10, a ratchet pawl 11 and a shaft rod 12. The ratchet wheel 10 is fixedly installed at one end of the roller shaft 6. The shaft rod 12 is movably inserted through the outer side wall of the connecting plate 8. One end of the shaft rod 12 is fixedly connected with the ratchet pawl 11. A reset elastic member 13 is further provided on the outer surface of the shaft rod 12. The two ends of the reset elastic member 13 are respectively fixedly connected with the inner side of the ratchet pawl 11 and the outer side wall of the connecting plate 8. The two ratchet pawls 11 are respectively engaged in the tooth grooves of the two ratchet wheels 10, and the two ratchet wheels 10 are arranged in the opposite direction to lock the rotation of the roller shaft 6 in both directions. Open the rope pressing component to loosen the end of the second hanging rope 2, press one of the ratchet pawls 11 to move one of the shaft rods 12. After the ratchet pawl 11 disengages from the tooth groove of the ratchet wheel 10, the roller shaft 6 is rotated in one direction to adjust the position of the connecting ring 5 on the surface of the second hanging rope 2;

[0061] It should be noted that the reset elastic member 13 is preferably a torsion spring. When the pawl 11 is rotated and bounced off by the ratchet wheel 10, the torsion spring drives the pawl 11 to re-engage with the tooth groove of the ratchet wheel 10 under the elastic force of the torsion spring.

[0062] Refer to Figures 4 - 6 As shown, the rope pressing assembly includes a fixed box 14 and a box cover 15 buckled on the top of the fixed box 14. A fixed column 16 around which the second suspension rope 2 is wound is fixed inside the fixed box 14. Pressing grooves 17 through which the second suspension rope 2 passes are respectively formed on the fixed box 14 and the box cover 15. In order to increase the pressing force on the second suspension rope 2, wear-resistant sheets 18 are provided in both pressing grooves 17 to increase the friction with the second suspension rope 2. A groove is formed on the box cover 15, and a positioning column 28 is installed at the bottom of one end of the box cover 15. A female buckle 29 matching the positioning column 28 is installed on the top of the fixed box 14, and the positioning column 28 is engaged with the female buckle 29;

[0063] Pass the end of the second suspension rope 2 through the two pressing grooves 17, and at least wind it around the fixed column 16 once when passing through. By rotating the box cover 15 to engage the positioning column 28 with the female buckle 29, at this time, the two pressing grooves 17 press the second suspension rope 2, and the wear-resistant sheet 18 is used to increase the friction with the second suspension rope 2, so that the second suspension rope 2 is not easily loosened, ensuring stable installation.

[0064] Refer to Figures 9 - 10 As shown, the installation pile includes two opposite installation frames 19 and a connecting frame 20. Clamping mechanisms are provided at the bottoms of the two installation frames 19. The connecting frame 20 is fixedly connected to the two installation frames 19 respectively. An installation head 21 for fixing the first suspension rope 1 is provided at the top of the connecting frame 20.

[0065] It should be noted that the installation head 21 is provided with a through hole through which the first suspension rope 1 passes, and one end of the first suspension rope 1 is buckled inward at the through hole, and a clamp-shaped fastener is used to fix it. One end of the first suspension rope 1 is folded inward to form a size larger than the through hole, so the first suspension rope 1 is not easily detached;

[0066] Refer to Figure 10 As shown, the clamping mechanism includes a fixed clamping plate 22 and a movable clamping plate 23. The fixed clamping plate 22 is fixedly installed at the bottom of the installation frame 19. The top of the movable clamping plate 23 is slidably installed at the bottom of the installation frame 19. A threaded adjusting rod 24 for driving the movable clamping plate 23 to move towards the fixed clamping plate 22 is provided on the fixed clamping plate 22. The threaded adjusting rod 24 is threadedly connected to the movable clamping plate 23. By screwing the threaded adjusting rod 24, the movable clamping plate 23 moves towards the fixed clamping plate 22. The installation pile is fixed on the top of the inclined roof through the two clamping plates to bear the weight and impact force of the safety rope.

[0067] Refer to Figure 8As shown, two opposite snap rings are fixed at one end of the suspension rope two 2, and the two snap rings are respectively slidably mounted on the outer surface of the suspension rope one 1;

[0068] In a preferred embodiment, the snap ring includes a fixed ring 25 and a connecting column 26. The fixed ring 25 has an opening. One end of the connecting column 26 is hinged to one end of the opening of the fixed ring 25. A fixing cap 27 is threadedly connected to the outer surface of the connecting column 26, and the other end of the fixing cap 27 is threadedly connected to the other end of the opening of the fixed ring 25. By screwing the fixing cap 27 so that it is located between the opening of the fixed ring 25 and the connecting column 26, at this time, the connecting column 26, the fixed ring 25 and the fixing cap 27 form a closed loop, and at this time, the snap ring is not easily detached from the surface of the suspension rope one 1. On the contrary, by screwing the fixing cap 27 so that its end away from the opening of the fixed ring 25, the opening of the fixed ring 25 is opened at this time, and the connecting column 26 is rotated. At this time, the snap ring can be detached from the surface of the suspension rope one 1.

[0069] Hang the two snap rings on the outer surface of the suspension rope one 1 respectively. When one of the snap rings falls off, the other snap ring can provide safety protection, achieving the effect of double protection.

[0070] Embodiment Two

[0071] In a specific embodiment, following the same structure detailed in Embodiment One, different from Embodiment Five, refer to Figure 11 As shown, according to the length of the top of the pitched roof, the suspension rope one 1 can have multiple segments, and the multiple segments are connected by a tightening device. It should be noted that the tightening device includes two opposite threaded sleeves 30 and two opposite conical inclined blocks 31. The two threaded sleeves 30 are connected by a threaded block 9. The inner walls of the two threaded sleeves 30 are inclined towards the middle, and the two conical inclined blocks 31 are respectively fitted to the inclined surfaces of the inner walls of the two threaded sleeves 30. The two conical inclined blocks 31 are respectively composed of two opposite half inclined blocks. The suspension rope one 1 passes through between the two half inclined blocks. Springs are provided at one ends of the two half inclined blocks and are fixed to the threaded block 9. When the suspension rope one 1 is pulled outwards, the two half inclined blocks approach each other along the inclined surfaces of the inner walls of the two threaded sleeves 30 and squeeze the suspension rope one 1, further improving the fixing effect on the suspension rope one 1.

[0072] Embodiment Three

[0073] Different from Embodiment 1, in order to further improve the rope pressing effect at the end of the suspension rope two 2 and prevent the safety problem of loosening caused by insufficient pressure, two fixing columns 16 are provided, and a gap is reserved between the two. A friction surface is provided on the surface of the fixing column 16, and the friction surface is used to increase the friction force with the suspension rope two 2 to ensure the anti-detachment effect of the suspension rope.

[0074] Inside the fixed box 14, there is a pushing member that pushes into the gap between the two fixing columns 16. The pushing member is used to press the second suspension rope 2 into the gap between the two fixing columns 16.

[0075] On the box cover 15, there is a pressing member that is used to drive the pushing member close to the gap between the two fixing columns 16.

[0076] The pushing member includes a guide plate 144 fixedly installed on the inner wall of the fixed box 14 and facing the fixing column 16, guide columns 145 distributed on both sides of the guide plate 144, and fixing seats 146 installed at both ends of the guide columns 145. A sliding seat 141 is slidably fitted on the guide plate 144 and the guide columns 145. An elastic body 143 is installed between the side of the sliding seat 141 facing the fixing column 16 and the fixing seat 146 located on the side close to the fixing column 16. A top column 142 facing the gap between the two fixing columns 16 is installed on the sliding seat 141. A friction surface is provided on the top column 142. The top of the sliding seat 141 is provided with an inclined surface sloping downward along the direction away from the fixing column 16.

[0077] The pressing member includes a pressing block 151 installed on the inner wall of the box cover 15 through a spring member. The bottom of the pressing block 151 is provided with an inclined surface sloping downward along the direction away from the fixing column 16. A ratchet structure for preventing backward movement is provided on the top surface of the guide plate 144.

[0078] When the box cover 15 is closed towards the fixed box 14, the pressing block 151 receives the resistance of the sliding seat 141 and compresses the spring member. When the compression reaches the limit, with the continuous closing action, the sliding seat 141 moves towards the side close to the fixing column 16, and then the top column 142 presses the second suspension rope 2 located between the two fixing columns 16 against the surface of the fixing column 16. After the pressing action is completed, the pressing block 151 is pushed outwards by the spring member immediately after separating from the sliding seat 141 until it is engaged with the ratchet structure for preventing backward movement, forming a limit on the rear side of the sliding seat 141 to prevent the fixing column 16 from loosening the second suspension rope 2, further improving the safety of the device.

[0082] S2. Assemble the first suspension rope 1: Fix the two ends of the first suspension rope 1 to the two installation piles respectively.

[0083] S3. Assemble the second suspension rope 2: Hang one end of the second suspension rope 2 on the outer surface of the first suspension rope 1 using two snap rings, so that the two snap rings can slide on the surface of the first suspension rope 1;

[0084] It should be noted that the usage method of the snap ring includes the following steps:

[0085] By turning the fixing cap 27 so that it is located between the opening of the fixing ring 25 and the connecting column 26, at this time, the connecting column 26, the fixing ring 25 and the fixing cap 27 form a closed loop, and at this time, the snap ring is not easily detached from the surface of the first suspension rope 1. On the contrary, turn the fixing cap 27 so that one end away from the opening of the fixing ring 25, at this time, the opening of the fixing ring 25 is open, and turn the connecting column 26, at this time, the snap ring can be detached from the surface of the first suspension rope 1.

[0086] S4. Assemble the hanging component: The operator first fastens the safety belt 7, passes the end of the second suspension rope 2 through the connecting ring 5 and winds it around the roller 6, and then uses the rope pressing component to clamp the end of the second suspension rope 2, where the number of turns of the second suspension rope 2 wound around the surface of the roller 6 is at least 2 turns;
