For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to the specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, the bridge pier cap top operation safety protection device provided by the embodiment of the utility model comprises a fixing ring 3, a buckle ring 4, a safety rope 5, a connecting buckle 6 and a safety belt 7;

[0024] There are two fixing rings 3, and the two fixing rings 3 correspond to the stoppers 2 on the left and right sides of the top of the pier cap 1 one by one. The structure of the fixing ring 3 is adapted to the structure of the stopper 2. The buckle ring 4 is provided on the opposite side of the two fixing rings 3, and the buckle ring 4 is a ring structure.

[0025] The connecting buckles 6 are provided at both left and right ends of the safety rope 5, and the connecting buckles 6 are connected to the buckle rings 4 on the corresponding sides thereof. The safety belt 7 is slidably mounted on the safety rope 5, and the safety belt 7 is used to fix the waist of the operator.

[0026] It should be noted that according to the cross-sectional shape and circumference of the block 2 of the pier cap 1, a Φ16mm round steel is bent into a rectangular closed ring, which is then welded to form a fixing ring 3. An 11mm steel wire inner core is provided inside the safety rope 5, and the safety rope 5 is injection molded outside, so as to have sufficient structural strength and facilitate sliding.

[0027] When the device is used, the two fixing rings 3 are respectively hooped on the two blocks 2 of the pier cap 1, and the operator's waist and safety belt 7 are fixed. The safety belt 7 is slidably installed on the safety rope 5, which can ensure that the safety belt 7 worn by the operator is firmly hung on the safety device when the operator works at any position on the top of the pier cap 1, completely eliminating the safety hazard of falling from height, and ensuring the safe production of the operator. The device has low processing cost, easy installation, and easy dismantling, which effectively ensures the safety of the operator during the operation on the top surface of the bridge pier cap 1 and prevents the occurrence of high-altitude falling accidents.

[0028] In the first embodiment, the fixing ring 3 and the buckle ring 4 are fixedly connected.

[0029] It should be noted that when the length of the pier cap 1 in the front-to-back direction is relatively short, the fixing ring 3 and the buckle ring 4 are fixedly connected, which can meet the needs of the operator to operate at any position on the top of the pier cap 1 .

[0030] In this embodiment, a fastening assembly is further included. The fastening assembly is arranged at a short side of the fixing ring 3 , and a fastening portion 8 of the fastening assembly is clamped between the short side of the fixing ring 3 and the side wall of the stopper 2 .

[0031] It should be noted that the fastening assembly is used to further fix the fixing ring 3 and the stopper 2 to prevent the fixing ring 3 from moving upward and sliding out of the stopper 2 .

[0032] In the second embodiment, the fastening portion 8 of the fastening assembly includes a rubber block, and the rubber block is a wedge-shaped structure.

[0033] It should be noted that after the rubber block is inserted between the short side of the fixing ring 3 and the side wall of the stopper 2, the rubber block can be compressed, thereby playing a fixing role. The wedge-shaped rubber block is easy to disassemble, and the large end of the wedge-shaped rubber block is located at the upper part of the fixing ring 3.

[0034] In the third embodiment, the fastening assembly includes a mounting portion and a fastening bolt, the mounting portion is mounted on the fixing ring 3 , and the end of the fastening bolt passes through the threaded hole on the mounting portion and abuts against the side wall of the stopper 2 .

[0035] It should be noted that the mounting portion can be a steel plate arranged on the fixing ring 3, the steel plate is provided with threaded holes, and the fastening bolts serve as the fastening portion 8. The fixing by the fastening bolts makes the fixing ring 3 have a better anti-slip effect.

[0036] In the fourth embodiment, the buckle ring 4 is slidably mounted on the fixing ring 3 .

[0037] It should be noted that when the length of the pier cap 1 in the front-to-back direction is long, the fixing ring 3 and the buckle ring 4 are slidably connected, thereby meeting the needs of the operator to operate at any position on the top of the pier cap 1.

[0038] In this embodiment, limit blocks 9 are provided on both the front and rear sides of the fixing ring 3 , and the limit blocks 9 cooperate with the buckle ring 4 .

[0039] It should be noted that the limit block 9 is arranged at a distance of one step from the front and rear edges of the stop block 2. The limit block 9 prevents the buckle 4 from sliding to the edge of the stop block 2 to prevent the operator from stepping on empty space.

[0040] In this embodiment, the connecting buckle 6 includes a safety hook, and a locking arm sleeve is provided on the locking arm of the safety hook.

[0041] It should be noted that the structural setting of the safety hook can improve the connection reliability and avoid the safety hazard of the connecting buckle 6 being disengaged.

[0042] In this embodiment, an anti-slip layer is provided on a side of the fixing ring 3 away from the safety rope 5 , and the anti-slip layer cooperates with the side wall of the stopper 2 .

[0043] It should be noted that the anti-skid layer of this embodiment can also prevent the fixing ring 3 from slipping out of the stopper 2, thereby improving the safety of the device. The anti-skid layer is made of rubber.

[0044] In this embodiment, the elongation of the safety rope 5 is less than 15%.

[0045] It should be noted that the elongation of the safety rope 5 is relatively small, thereby improving the reliability of the operator when moving.

[0046] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiment, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
