Description
Technical Field
[0001] The present application relates to the field of life safety rope transition devices, and in particular to an automatic transition device for the middle fixed end of a life safety rope. Background Art
[0002] During the construction of the cap beam of the highway viaduct, operations such as cap beam reinforcement, support shim stone, and support installation are required. A safety life rope needs to be set up for height operations to facilitate the hanging of safety belts for height operations.
[0003] Common safety life rope devices only adopt the situation that fixed columns are set at both ends, or transition columns are set in the middle. However, when the safety belt moves along the safety life rope, it is generally unable to pass smoothly. In most cases, it is necessary to open the safety belt buckle and then re-hang it on the safety rope on one side of the middle column. In many cases, such operations need to be repeated many times. In this process, since the safety belt is in a state of no hanging point, the anti-fall construction requirements cannot be achieved throughout the whole process, and there are certain safety risks.

DETAILED DESCRIPTION
[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" 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 direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0033] The embodiment of the present application discloses an automatic transition device for the middle fixed end of a life safety rope.
[0034] like Figures 1 to 3As shown, the automatic transition device for the middle fixed end of the life safety rope includes an end column 1, a middle column 2, a safety life rope 3, a transition frame 4 and an anti-rope-off device 5. Two end columns 1 are provided, and one middle column 2 is provided. The middle column 2 is installed between the two end columns 1. In actual use, the number of the middle columns 2 can be increased according to the installation distance of the two end columns 1. The end columns 1 are preferably set as disc-type steel pipes. The two ends of the safety life rope 3 are fixed to the end columns 1 at both ends by wire rope clamps. The safety life rope 3 uses a wire rope with a diameter of 16 mm. The transition frame 4 is installed on the middle column 2. The safety life rope 3 passes through the transition frame 4. The transition frame 4 is provided with a safety belt slide 41 for the safety belt to pass through. The anti-rope-off device 5 is installed on the transition frame 4 to block the safety belt slide 41.
[0035] like Figure 4 and Figure 5 As shown, the anti-rope-off device 5 includes a rolling control drum 51 and a baffle 52. The rolling control drum 51 includes a mounting shell 511, a support ring 512 and a bearing 513. The bearing 513 is mounted on a transition frame. The support ring 512 is coaxially and fixedly connected to the bearing 513. Four rotating rods 514 are arranged at both ends of the support ring 512. The rotating rods 514 are arranged at equal intervals on the circumferential part of the support ring 512. The four rotating rods 514 are commonly connected to a swivel 515. The swivel 515 is coaxially arranged with the support ring 512. An annular groove 5111 is opened on the inner side wall of the mounting shell 511 corresponding to the two swivels 515. A plurality of balls 6 are installed in the annular groove 5111. The swivel 515 is rotatably connected in the annular groove 5111. The outer side wall of the swivel 515 is in point contact with the plurality of balls 6. Four baffle rods 52 are arranged. The four baffle rods 52 are arranged at equal intervals on the circumferential part of the outer side wall of the mounting shell 511.
[0036] In the embodiment itself, it also includes an elastic sheet 516 and a limiting rod 517. Four elastic sheets 516 are provided. The four elastic sheets 516 are arranged at intervals relative to the four blocking rods 52. The elastic sheets 516 are installed between adjacent blocking rods 52. The angle between the axis of the center island swivel 515 of the adjacent elastic sheets 516 is 90°. The limiting rod 517 is installed on the swivel 515. A limiting groove 42 is provided on the transition frame 4 corresponding to the blocking rod 52. When one blocking rod 52 rotates to the outside of the limiting groove 42, the other blocking rod 52 immediately rotates into the limiting groove 42, thereby ensuring that there is always a blocking rod 52 that can cooperate with the limiting groove 42 to block the seat belt slide 41.
[0037] The implementation principle of the automatic transition device of the middle fixed end of the life safety rope in the embodiment of the present application is as follows: the blocking rod 52 is located in the limiting groove 42, and cooperates with the limiting groove 42 to block the safety belt slide groove 41, thereby preventing the safety life rope 3 from escaping from the transition frame 4. When the staff needs to move from one side of the middle column 2 to the other side, the rotating rod 514 is manually rotated and the safety belt back rope is used to apply a force to the rotating rod 514 to drive the rotating rod 514. The rotating rod 514 rotates and drives the installation shell 511 to rotate, and the elastic sheet 516 is squeezed by the limiting rod 517 from Due to compression deformation, the ball 6 in the mounting shell 511 rotates, thereby reducing the friction between the mounting shell 511 and the swivel 515. The mounting shell 511 is restricted by the elastic sheet 516 and the limiting rod 517, and each time a blocking rod 52 rotates to the outside of the limiting groove 42, the adjacent blocking rod 52 rotates to the inside of the limiting groove 42, thereby ensuring that there is always a blocking rod 52 that can cooperate with the limiting groove 42 to block the safety belt slide 41, preventing the safety life rope 3 from detaching from the transition frame 4, and reducing the safety risk when the safety belt passes through the middle column 2.
[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
