Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of safety net installation technology, and more specifically, to an assembled under-hanging safety net clamp. Background Technology

[0002] In the construction of steel structures in building engineering, a large number of steel beams need to be hoisted and installed. Workers need to be on suspended operating platforms to hoist and weld the steel structures. During the operation, workers are prone to falling accidents, which pose safety hazards. Safety nets are a commonly used safety measure to prevent falls in the construction industry.

[0003] In most current construction sites, the traditional method of using hooks and ropes to hang safety nets is still prevalent. S-shaped hooks are used to thread the ropes, and the nets are haphazardly attached. Because the hooks are fixed in position and lack any tensioning mechanism, the safety net ropes are in a completely slack, free-hanging state. When a slack section is subjected to force, the impact kinetic energy cannot be quickly transferred across the entire net surface; it is only borne by a few local ropes, making it extremely easy for the ropes to break or the hooks to come loose, thus losing its protective function. Therefore, a prefabricated hanging safety net clamp capable of tightening the safety net ropes is designed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an assembled under-hanging safety net clamp.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses an assembled under-hanging safety net clamp, including a steel beam fastening platform, fasteners disposed on the upper and lower sides of the steel beam fastening platform, and a safety net rope fastener disposed on one side of the steel beam fastening platform for connecting the safety net rope. The safety net rope fastener includes a safety net rope winding component and a safety net rope clamping component. The safety net rope winding component includes an outer frame, a winding rod located inside the outer frame, and an L-shaped insert rod for controlling the rotation of the winding rod. The safety net rope clamping component disposed on the winding rod includes a U-shaped clamping frame and a retaining ring.

[0006] Preferably, the outer frame includes a rear frame and a front frame connected by screws. Both the rear frame and the front frame are U-shaped. The rear frame is bolted to the steel beam fastening base. Safety net rope through holes are provided on both the front and rear sides of the front frame.

[0007] Preferably, both ends of the winding rod are provided with fixing plates, and the two fixing plates are respectively screwed to the rear frame and the front frame. The rear end of the winding rod is rotatably connected to the fixing plate with a fixing post, and the front end of the winding rod passes through both the fixing plate and the front frame, with its front end face extending beyond the outer side of the outer frame.

[0008] Preferably, the outer end of the winding rod is provided with a connecting groove for the L-shaped insert rod to pass through, and a limiting member is provided between the L-shaped insert rod and the winding rod. The limiting member includes a top plate and an insert post that is screwed to the top plate.

[0009] Preferably, the winding rod has a slot inside for inserting the plug, a connecting post is fixed at the bottom of the slot, the plug has a connecting cavity inside that matches the connecting post, a slot is provided on the outside of the plug, and a locking block that matches the slot is fixed on the inner wall of the slot.

[0010] Preferably, at least three insert blocks are fixed on the inner side of the top plate, and the outer end face of the winding rod is provided with an insertion hole adapted to the insert blocks. Both the insert blocks and the locking blocks are made of rubber.

[0011] Preferably, a pad is fitted on the outer side of the winding rod, and the pad is screwed to the outer side of the outer frame. The pad is made of either polyoxymethylene or nylon modified material.

[0012] Preferably, the clamping frame is installed on the upper side of the winding rod, the retaining ring is disposed at the upper end of the clamping frame, and two symmetrical flanges are fixedly disposed at the upper end of the clamping frame, with the retaining ring inserted into the flanges.

[0014] Preferably, at least one safety net rope clamp is provided on the outer side of the winding rod, the clamp frame is screwed to the winding rod, and the clamp frame is made of stainless steel or aluminum alloy.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a winding rod to partially wind up a certain length of the safety net rope, changing the drooping section from slack to taut. This improves the safety net's interception, buffering, and overall load-bearing capacity.

[0019] like Figure 1-8 As shown, this utility model provides an assembled hanging safety net clamp, including a steel beam fastening platform 1, fasteners 2 disposed on the upper and lower sides of the steel beam fastening platform 1, and a safety net rope 5 fastener disposed on one side of the steel beam fastening platform 1 for connecting the safety net rope 5. The safety net rope 5 fastener includes a safety net rope winding component 3 and a safety net rope clamping component 4. The safety net rope winding component 3 includes an outer frame, a winding rod 33 located inside the outer frame, and an L-shaped insert rod 36 for controlling the rotation of the winding rod 33. The safety net rope clamping component 4 disposed on the winding rod 33 includes a U-shaped clamping frame 41 and a retaining ring 43.

[0020] Furthermore, in this embodiment, the outer frame includes a rear frame 31 and a front frame 32 connected by screws. Both the rear frame 31 and the front frame 32 are U-shaped designs. The rear frame 31 is bolted to the steel beam fastening base 1. The bolts are high-strength bolts. Safety net rope through holes 321 are provided on both the front and rear sides of the front frame 32. The safety net rope through holes 321 allow the safety net rope 5 to pass through the outer frame. The safety net rope 5 can also pass directly through the hollow frame formed by the two U-shaped front and rear frames 31.

[0021] In this embodiment, both ends of the winding rod 33 are provided with fixing plates 34. The two fixing plates 34 are screwed to the rear frame 31 and the front frame 32 respectively. The fixing plates 34 are fixed by the front and rear frames 31. The rear end of the winding rod 33 is rotatably connected to the fixing plate 34 with a fixing post 38. The front end of the winding rod 33 passes through both the fixing plate 34 and the front frame 32, so that the winding rod 33 rotates on the outer surface of the fixing post 38 and rotates inside the fixing plate 34 and the front frame 32. Its front end face extends beyond the outer side of the outer frame, and the extended part is used to connect with the L-shaped insert rod 36.

[0022] In this embodiment, the outer end of the winding rod 33 is provided with a connecting groove 331 for the L-shaped insert rod 36 to pass through. The L-shaped insert rod 36 passes through the connecting groove 331. A limiting member 37 is provided between the L-shaped insert rod 36 and the winding rod 33. The limiting member 37 includes a top plate 371 and an insert post 372 that is screwed to the top plate 371. The cross sections of the top plate 371 and the insert post 372 are T-shaped.

[0023] In this embodiment, the inside of the take-up rod 33 is provided with a slot for inserting the pin 372. A connecting pin 332 is fixed at the bottom of the slot. The inside of the pin 372 is provided with a connecting cavity 373 that is adapted to the connecting pin 332. A slot 374 is provided on the outside of the pin 372. A locking block 333 that is adapted to the slot 374 is fixed on the inner wall of the slot. The pin 372 of the limiting frame is inserted into the slot at the end of the take-up rod 33. At the same time, the connecting pin 332 in the slot is connected to the connecting cavity 373 of the pin 372. The outer surface of the pin 372 is connected to the locking block 333 in the slot on the take-up rod 33 through the slot 374, so as to realize the connection between the limiting member 37 and the L-shaped pin 36 and the take-up rod 33.

[0024] In this embodiment, at least three insert blocks 375 are fixed on the inner side of the top plate 371, and the outer end face of the winding rod 33 is provided with an insertion hole that matches the insert block 375. Both the insert block 375 and the locking block 333 are made of rubber.

[0025] In this embodiment, a pad 35 is fitted on the outer side of the winding rod 33. The pad 35 is screwed to the outer side of the outer frame. The pad 35 is made of either polyoxymethylene or nylon modified material. The design of the pad 35 reduces the wear of the L-shaped insert rod 36 on the front frame 32.

[0026] It should be noted that, considering that the L-shaped insert rod 36 may experience reverse force when controlling the winding rod 33 to rotate and wind, causing the winding rod 33 to be unable to effectively wind, when the winding rod 33 has completed a certain winding and tightening of the safety net rope 5, a limiting member 37 is used to open a corresponding slot and connecting post 332 in the pad 35 to connect the L-shaped insert rod 36 to the pad 35, thereby temporarily fixing the L-shaped insert rod 36. The length of the limiting member 37, which serves this function, needs to be adjusted with the distance between the L-shaped insert rod 36 and the pad 35 to ensure that the engagement between the slot 374 and the block 333 is inside the pad 35 and not exposed.

[0027] In this embodiment, the clamping frame 41 is installed on the upper side of the winding rod 33, and the retaining ring 43 is disposed at the upper end of the clamping frame 41. Two symmetrical flanges 42 are fixedly disposed at the upper end of the clamping frame 41. The retaining ring 43 is inserted into the flanges 42, and the opening end of the clamping frame 41 is tightened by the cooperation between the retaining ring 43 and the flanges 42.

[0028] In this embodiment, a stop bar 44 is fixed to the inner side of the retaining ring 43. One end of the stop bar 44 abuts against the rear end of one of the flanges 42, and the other end of the stop bar 44 abuts against the front end of another flange 42. The design of the stop bar 44 prevents the retaining ring 43 from rotating on the flange 42. A limiting member 37 is installed between the retaining ring 43 and the end of the outer frame. The position of the retaining ring 43 is limited by the limiting member 37. The clamping frame 41 is provided with slots, connecting posts 332, etc. that cooperate with the limiting member 37.

[0029] It should be noted that, considering the size of the hanging safety net and the actual stress conditions, in order to ensure the firmness of the clamping frame 41, the retaining ring 43 and the clamping frame 41 can also be fixed with high-strength bolts to prevent the retaining ring 43 from detaching.

[0030] In this embodiment, at least one safety net rope clamp 4 is provided on the outer side of the winding rod 33. The clamp frame 41 is screwed to the winding rod 33. The clamp frame 41 is made of stainless steel or aluminum alloy. The material of the clamp frame 41 allows it to be tightened by the retaining ring 43.

[0031] It should be noted that, considering the adaptability of the clamp, in order to accommodate safety net ropes 5 of different diameters, the clamping frame 41 selects a suitable retaining ring 43 according to the required tightening size of the clamping frame 41, and tightens the open end of the clamping frame 41.

[0032] Specifically, the installation process for the hanging safety net is as follows: S0, the steel beam fastening platform 1 is U-shaped. Fasteners 2 are provided on both the upper and lower sides of the steel beam fastening platform 1. The fasteners 2 include a fastening screw 21 that passes through the steel beam fastening platform 1 and a pressure plate 22 located on the inner side of the steel beam fastening platform 1.

Check whether the fixture can be used normally, including whether the bolt / screw connection is firm and whether the fastening screw 21 can rotate normally. S1. Select the installation position of the clamp according to the stress point of the hanging safety net, clamp the steel beam 6 fastening platform on the steel beam 6, and the steel beam 6 fastening platform is close to the outside of the steel beam 6. At this time, the pressure plate 22 is located on the upper and lower sides of the steel beam 6 and is not in contact. Continue to rotate the fastening screw 21 clockwise. The fastening screw 21 moves down along the threaded hole, and the pressure plate 22 descends accordingly until its inner side is completely in contact with the surface of the steel beam 6. Continue to tighten until the fastening screw 21 cannot be easily rotated, and there is no relative wobbling between the steel beam 6 fastening platform and the steel beam 6. The clamp is in a "fixed" state. S2, place the rear frame 31 against the side of the steel beam fastening base 1, align the bolt holes, insert the high-strength bolts and tighten them, insert the safety net rope 5 through the U-shaped space of the rear / front frame 32 (or through the through hole of the front frame 32), the remaining part of the safety net hangs down naturally, and the safety net rope 5 in the rear / front frame 32 is inserted into the U-shaped clamping frame 41, the rope body is close to the inside of the clamping frame 41, put the retaining ring 43 into the opening end of the clamping frame 41, press it down to the root of the flange 42, one end of the retaining ring 43 abuts against the rear end of the front flange 42 and the other end abuts against the front end of the rear flange 42, the retaining ring 43 cannot rotate, the opening of the clamping frame 41 is tightened, and the safety net rope 5 is clamped; S3. Slowly rotate the L-shaped plug 36 clockwise. The L-shaped plug 36 drives the winding rod 33 connected to it to rotate synchronously. The winding rod 33 rotates inside the fixed plate 34. The safety net rope 5 begins to wrap around the outside of the rod. The net rope gradually tightens and the drooping section is pulled tight from slack. When the resistance feels significantly increased and the net rope appears to be taut, stop rotating. S4, remove the limiting piece 37, align the insert post 372 with the slot on the end face of the pad 35, align the connecting post 332 with the connecting cavity 373, push it in to the bottom, the locking block 333 engages with the locking groove 374, the insert block 375 of the top plate 371 is pressed into the insertion hole, the top plate 371 is in close contact with the surface of the L-shaped insert rod 36, the L-shaped insert rod 36 is completely restricted, the winding rod 33 is in a "non-rotatable" locked state, if winding is needed again, the limiting piece 37 can be removed, so that the L-shaped insert rod 36 can rotate; S5. Finally, check that there are no visible gaps between the steel beam fastening platform 1 and the steel beam 6, that the retaining ring 43 and the clamping frame 41 do not wobble, that the winding rod 33 cannot be manually rotated, and that the pad 35 is tightly attached to the outer frame. S6, when dismantling is required, first remove the limit piece 37, rotate the L-shaped insert 36 counterclockwise to drive the winding rod 33 to rotate, the safety net rope 5 gradually loosens and the tension disappears, remove the retaining ring 43, open the clamping frame 41, take out the safety net rope 5, loosen the fastening screw 21 of the steel beam fastening platform 1, the pressure plate 22 rises, and the steel beam fastening platform 1 can be removed from the steel beam 6.

[0033] It should be noted that the safety net rope 5 can only be wound to a certain extent. When winding, it is necessary to observe whether the safety net rope 5 is tangled. The purpose is to tighten the safety net and improve the interception effect of the entire net. Generally, the size of the safety net is matched with the location of use.
