[0002] In the process of steel structure construction involving bolts, in the construction stage where the aerial work platform has not been completed, or in the environment where there is no guardrail for the side work, workers are often required to climb to high altitudes with the protection of safety belts to carry out work. There are two commonly used methods at present: one is to set up a safety rope and hang the safety belt on the safety rope; the other is to temporarily hang a fall arrester on the top of the steel structure, and then hang the safety belt hook on the fall arrester. However, in the process of installing and removing the safety rope and fall arrester, the high-altitude workers lack safety protection, so if the workers make some mistakes in their operations during this time, they may seriously threaten their own lives. In addition, both the safety rope and the fall arrester have load limits. One safety rope corresponds to two people at most, and one fall arrester corresponds to one person; and the setting of the safety rope may affect the on-site lifting and hoisting, the travel of personnel, etc. in terms of space, and the cost of setting up a fall arrester at each work point may increase a lot.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The utility model provides a safety belt suspension buckle, which comprises a belt ring 1, a one-way rotating part, a quick-release part and a flexible suspension part.

[0035] The flexible suspension part includes a rotating drum 10, a baffle 11 and a flexible belt 12. The baffles 11 are welded to both ends of the rotating drum 10. An arc-shaped hanging plate 13 is fixed to the rotating drum 10 by screws. A hanging ring 14 is provided at one end of the flexible belt 12 and is hinged to the hanging plate 13. Figure 7 As shown, a hook 15 is provided at one end of the flexible belt 12 away from the hanging ring 14; one end of the flexible belt 12 is connected to the belt body through the hook 15 to form a flexible hanging ring.

[0036] During the construction process, studs C are densely welded on the steel structure components. Figure 1 It can be seen that the flexible belt 12 is sleeved on the bolt C through the flexible hanging ring at one end. By rotating the drum 10, the winding length of the flexible belt 12 on the drum 10 is increased, the flexible belt 12 is tightened, and the flexible hanging ring is clamped on the bolt C, thereby achieving the purpose of the utility model suspension buckle to fix the safety belt on the bolt C; conversely, by reversing the drum 10, the winding length of the flexible belt 12 on the drum 10 is reduced, the flexible belt 12 is loosened, and the flexible hanging ring is loosened and enlarged, the flexible hanging ring can be removed from the bolt C, and the purpose of the utility model suspension buckle to remove the safety belt from the bolt C is achieved. The function of the baffle 11 is to limit the flexible belt 12 wound on the drum 10 to prevent the flexible belt 12 from falling off the drum 10.

[0037] The one-way rotating portion includes a side cover 2 , a fixed plate 3 and a rotating plate 4 .

[0038] The fixed disk 3 is in the shape of a round pancake, and a concentric fixed rod 301 and a rotating rod 302 are welded at the center positions on both sides of the fixed disk 3. A groove is opened on the side of the fixed disk 3, and a ratchet 303 is matched in the groove through the rotation of the rotating shaft. An arc spring 304 is arranged between the ratchet 303 and the inner side wall of the groove of the fixed disk 3. A support block 305 is welded on the outside of the fixed disk 3, and the support block 305 is close to the groove of the fixed disk 3 and is located on the side of the outer rotation direction of the ratchet 303.

[0039] The side cover 2 is in the shape of a circular plate, and one side of the side cover 2 is welded to the belt ring 1. The safety belt is connected to the belt ring 1 through a hook D. The side of the side cover 2 away from the belt ring 1 is processed with an outer edge with an L-shaped cross section. The side of the side cover 2 away from the belt ring 1 is also processed with a connecting tube 201, and the connecting tube 201 is interference-fitted with the fixing rod 301.

[0040] The rotating disk 4 is in the shape of a round pancake, and is processed with a circular inner cavity with an opening on one side, and the side of the inner cavity of the rotating disk 4 is processed with gear teeth that match the ratchet 303. A cylindrical protrusion 401 is welded in the center of the closed side of the rotating disk 4, and the cylindrical protrusion 401 is concentric with the rotating disk 4. A through rotating hole is opened inside the cylindrical protrusion 401, and the rotating hole passes through the closed side of the rotating disk 4. The fixed disk 3 is arranged in the inner cavity of the rotating disk 4, and the rotating rod 302 is rotatably fitted in the rotating hole. The open side of the rotating disk 4 is processed with a circular outer edge, and the outer edge of the rotating disk 4 is rotatably matched with the outer edge of the side cover 2, and the outer edge end of the rotating disk 4 is located inside the side cover 2.

[0041] By combining the above Figure 5 and Figure 6 It can be seen that the one-way rotating part is designed based on the principle of the ratchet mechanism, the side cover 2 and the fixed disk 3 are connected and fixed, and the rotating disk 4 is unidirectionally rotated relative to the side cover 2 and the fixed disk 3. When the rotating disk 4 rotates unidirectionally, the gear teeth of the rotating disk 4 push the pawl 303 to rotate toward the inside of the groove of the fixed disk 3. After the gear teeth pass the position of the pawl 303, the pawl 303 is reset and rotated by the force of the arc spring 304, and the cycle is repeated. When the rotating disk 4 reverses, the gear teeth push the pawl 303 to rotate outward from the fixed disk 3 until the pawl 303 contacts the support block 305. At this time, the pawl 303 reaches the end of the rotation stroke and cannot move, and then the rotating disk 4 is locked and cannot rotate in the reverse direction. The one-way rotating part is connected to the flexible suspension part through the quick-release part. Since the winding direction of the flexible belt 12 on the drum 10 is the same as the one-way rotation direction of the rotating disk 4, the flexible suspension part rotates unidirectionally following the one-way rotating part, that is, the flexible belt 12 can only increase the winding length on the drum 10, thereby achieving the goal of keeping the belt body of the flexible belt 12 taut, ensuring that the flexible hanging ring of the flexible belt 12 is firmly clamped on the bolt C, and has a strong anti-slip effect.

[0042] The quick-release part includes a positioning terminal 5, a sleeve 6, a connector 7 and a connecting rod 8. The positioning terminal 5 is welded to the end of the cylindrical protrusion 401 away from the rotating disk 4. A through hole matching the connector 7 is provided in the positioning terminal 5, and the diameter of the through hole is smaller than the diameter of the rotating hole in the cylindrical protrusion 401. One end of the sleeve 6 is welded to the closed side of the rotating disk 4. A stepped hole running through both ends is provided in the sleeve 6, and the large hole is close to the rotating disk 4. The cylindrical protrusion 401, the positioning terminal 5 and the connector 7 are located in the stepped hole of the sleeve 6. The connecting rod 8 is a stepped shaft matching the stepped hole of the sleeve 6. The connecting rod 8 is movably arranged in the sleeve 6, and the thin rod end of the connecting rod 8 can extend out of the sleeve 6. One end of the thick rod of the connecting rod 8 is welded to the end of the connector 7 away from the cylindrical protrusion 401; the end of the connecting rod 8 away from the connector 7 is welded to the baffle 11 at one end of the rotating drum 10. A locking member 9 is provided between the connecting rod 8 and the sleeve 6 .

[0043] The quick release part is designed to connect the one-way rotating part and the flexible suspension part, and is used to adjust the two connection states between the two, namely, locking and disengaging. The positioning end 5, the connecting head 7 and the connecting rod 8 are arranged inside the sleeve 6, and the three are assembled together and cannot be separated, but the connecting head 7 and the connecting rod 8 are welded, and the two can move inside the sleeve 6.

[0044] When the one-way rotating part and the flexible suspension part are in a locked state, the connecting head 7 is located in the through hole of the positioning end 5, the locking piece 9 is in a locked state, and the sleeve 6 and the connecting rod 8 are kept in fixed position by the locking piece 9, and thus the positions of the connecting head 7 and the positioning end 5 are also kept fixed. At this time, the flexible suspension part rotates unidirectionally following the one-way rotating part.

[0045] When the one-way rotating part and the flexible suspension part are in a disengaged state, the locking piece 9 is unlocked, the connecting head 7 and the connecting rod 8 can move in the sleeve 6, and the connecting head 7 can be separated from the positioning end head 5. At this time, the one-way rotating part and the flexible suspension part are in a separated state, and the flexible suspension part does not rotate unidirectionally with the one-way rotating part, that is, the rotating drum 10 can be freely reversed, and the flexible belt 12 can freely adjust the winding length on the rotating drum 10, adjust the tightness of the flexible belt 12, and the staff can relax the belt body of the flexible belt 12 to make the flexible hanging ring of the flexible belt 12 loose and larger, and remove the flexible hanging ring from the bolt C, thereby achieving the purpose of removing the safety belt from the bolt C by the suspension buckle of the utility model.

[0046] The locking member 9 includes a latch 901, a stopper 902 and a locking plate 903. The stopper 902 is welded to one end of the latch 901, and the diameter of the stopper 902 is larger than that of the latch 901. A blind hole matching the size of the stopper 902 is provided on the connecting rod 8; a stepped hole matching the latch 901 and the stopper 902 is provided on the sleeve 6, the thin hole is close to the outside of the sleeve 6, and the thick hole is close to the inside of the sleeve 6. The latch 901 passes through the stepped hole of the sleeve 6 through one end of the stopper 902 and extends into the blind hole of the connecting rod 8. One end of the locking plate 903 is rotatably arranged on the sleeve 6 through a rotating shaft, and a locking groove matching the latch 901 is provided on the end of the locking plate 903 away from the rotating shaft. A marking groove 1101 is provided on the side of the baffle 11 where the flexible suspension part is welded to the connecting rod 8 at the position corresponding to the blind hole of the connecting rod 8.

[0047] The marking groove 1101 plays a positioning role. When the one-way rotating part and the flexible suspension part need to be locked, when the marking groove 1101 is in the position corresponding to the latch 901, the latch 901 and the limit head 902 can be inserted into the blind hole of the connecting rod 8, and the locking plate 903 is clamped and fixed with the latch 901 through the locking groove, and the connecting rod 8 and the sleeve 6 are locked in position; when the one-way rotating part and the flexible suspension part need to be disengaged, the locking plate 903 is rotated so that the locking plate 903 and the latch 901 do not interfere with each other, and then the latch 901 is pulled out. When the limit head 902 is located in the stepped hole of the sleeve 6, the locking piece 9 completely cancels the locking, the one-way rotating part and the flexible suspension part are completely disengaged, and the connecting rod 8 can move in the sleeve 6.

[0048] The specific usage and function of this embodiment are as follows:

[0049] Before performing high-altitude climbing operations, first check whether the suspension buckle of the safety belt is in a locked state. If it is not locked, position it according to the marking groove 1101, rotate the baffle 11, and then operate the locking member 9 to complete the locking. When the worker starts to climb upward, first operate a safety belt with a suspension buckle. Select the bolt C at the suspension point above the worker, put the flexible hanging ring of the flexible belt 12 on the bolt C, the flexible belt 12 is pulled by force, and the flexible hanging ring is clamped on the bolt C to complete the fixing of the first safety belt. The worker then climbs up. During the climbing process, he feels that the flexible belt 12 is loose and can rotate the baffle plate 11 to drive the flexible suspension part to rotate. The flexible suspension part is acted upon by the one-way rotating part, and the flexible belt 12 can only increase the winding length on the drum 10, thereby making the flexible belt 12 belt body tight. After climbing to a certain distance, the first safety belt is in a hand-operable position below the body relative to the worker. At this time, the worker repeats the above operation to fix the second safety belt on the bolt C at the hanging point above the human body. Then, he operates the first safety belt with one hand, operates the locking member 9 to cancel the locking, and then moves the flexible suspension part to make it disengaged from the one-way rotating part. At this time, the flexible suspension part can be reversed to reduce the winding length of the flexible belt 12 on the drum 10, and the flexible belt 12 belt body is relaxed. The flexible hanging ring of the flexible belt 12 is relaxed and becomes larger, and the flexible hanging ring can be removed from the bolt C to complete the disassembly of the first safety belt. Then, the baffle plate 11 is rotated again, positioned according to the marking groove 1101, and the locking member 9 is operated to complete the locking. Afterwards, the staff climbs upward again, and after climbing to a certain distance, fixes the disassembled safety belt to the hanging point above the human body, and removes the previously installed safety belt. As can be seen from the above, changes in various directions such as up, down, left, and right can be achieved by changing the fixed positions of the two safety belts on the steel structure in turn, thereby realizing the position change of the staff.

[0050] In summary, compared with the prior art, the utility model always ensures that a safety belt is fixed to the steel structure during the movement of the workers. Compared with the prior art, it effectively reduces the risks of the workers during climbing and altitude operations.
