[0046] Please refer to Figures 1 to 8 for a description of the safety protection device applied to the capping beam provided in this application. The safety protection device applied to the capping beam proposed in this application includes two connecting members, two vertical rods 10, and a safety rope 20.

[0047] The two connecting members are respectively used to be fixed on two stoppers 200 on both sides of the capping beam 100, and the two vertical rods 10 are respectively fixedly connected to the two connecting members and extend upward from bottom to top. The safety rope 20 is arranged between the two vertical rods 10 and is connected to the tops of the two vertical rods 10, so that the safety rope 20 is arranged horizontally on the upper side of the capping beam 100.

[0048] In this embodiment, the connecting member includes a connecting plate 1, an outer baffle 2, an adjusting plate 3, and an inner baffle 4.

[0049] The connecting plate 1 is connected to the bottom end of the corresponding vertical rod 10, and it has a plurality of support rods 5 arranged at intervals along the length direction of the capping beam 100; among them, each support rod 5 is used to support on the upper side surface of the stopper 200 and extends to the inner and outer sides of the stopper 200 along the width direction of the capping beam 100.

[0050] The outer baffle 2 is used to be arranged on the outer side of the stopper 200 and is fixedly connected to the plurality of support rods 5 to fit on the outer side surface of the stopper 200 (i.e., the horizontal surface of the stopper 200).

[0051] The adjusting plate 3 is used to be arranged on the surface of the capping beam 100 and is located inside the stopper 200; and this adjusting plate 3 is slidably connected to the plurality of support rods 5 one by one through a plurality of sliders 9, and there is a first locking structure 6 between each slider 9 and the corresponding support rod 5; during actual use, the first locking structure 6 can be separated to control the relative position of the adjusting plate 3 and the support rod 5, and the relative position of the adjusting plate 3 and the support rod 5 can also be fixed by connecting the first locking structure 6.

[0052] The inner baffle 4 is hinged to the side of the adjusting plate 3 facing the stop block 200 along the length direction of the capping beam 100, so as to be adapted to swing to be parallel to the inner side surface of the stop block 200 (i.e., the inclined surface of the stop block 200); based on this, by changing the relative positions of the adjusting plate 3 and the stop block 200, the inner baffle 4 can be arranged to fit the inner side surface of the stop block 200; and, a second locking structure 7 is provided between the inner baffle 4 and the adjusting plate 3, and the relative movement between the inner baffle 4 and the adjusting plate 3 can be restricted through the second locking structure 7.

[0053] In the embodiment of the present application, by connecting the vertical rod 10 and the stop block 200 through a connecting member, the rapid and matching connection between the vertical rod 10 and the capping beam 100 can be realized; specifically, the support rod 5 is supported on the upper side surface of the stop block 200, and the adjusting plate 3 and the outer baffle 2 are respectively located on the inner and outer sides of the stop block 200; then, the adjusting plate 3 is moved to drive the inner baffle 4 to swing, so that the inner baffle 4 and the outer baffle 2 can respectively fit the inner and outer sides of the stop block 200 to clamp the stop block 200 and restrict the relative movement between the connecting member and the stop block 200.

[0054] Compared with the prior art, the safety protection device applied to the capping beam provided in this embodiment can realize the rapid assembly and disassembly of the vertical rod 10 and ensure the overall efficiency of the high-altitude operation above the capping beam 100.

[0055] In some embodiments, such as Figure 3 and Figure 7 shown, the second locking structure 7 includes a strip-shaped hole 71 and a swing arm 72.

[0056] The strip-shaped hole 71 is opened on the adjusting plate 3 and penetrates from the side of the adjusting plate 3 facing the inner baffle 4 to the side of the adjusting plate 3 facing away from the inner baffle 4 and extends in the up-down direction.

[0057] The swing arm 72 is hinged to the side of the inner baffle 4 facing the adjusting plate 3, and the hinge axis is parallel to the hinge axis of the inner baffle 4, so as to be adapted to swing to a horizontal state and be inserted into the strip-shaped hole 71.

[0058] Wherein, two stoppers 721 are provided on the swing arm 72, and the two stoppers 721 are respectively used to abut against the two sides of the adjusting plate 3 facing and facing away from the inner baffle 4 to restrict the swinging of the swing arm 72 and the inner baffle 4.

[0059] In some embodiments, such as Figure 3 shown, the swing arm 72 is a screw rod, and the stopper 721 is a nut threadedly connected to the screw rod. By manually controlling the rotation of the stopper 721 relative to the swing arm 72, the stopper 721 can be driven to move along the length direction of the swing arm 72.

[0060] In some embodiments, such as Figure 3As shown, there are multiple sets of the second locking structures 7, and the multiple sets of the second locking structures 7 are arranged at intervals along the length direction of the capping beam 100 to cooperate with enhancing the locking effect.

[0061] In some embodiments, as Figure 3 and Figure 4 shown, multiple support rods 5 are connected by a blocking plate 51, and the slider 9 is located between the blocking plate 51 and the connecting plate 1.

[0062] By adopting the above technical solution, both the blocking plate 51 and the connecting plate 1 are used to abut against the slider 9 to limit the movement of the slider 9 and avoid the separation of the slider 9 and the support rod 5.

[0063] In some embodiments, as Figure 5 and Figure 6 shown, the slider 9 is provided with a guiding hole 91, and the support rod 5 is slidably inserted into the guiding hole 91 to realize the sliding connection relationship between the adjusting plate 3 and the support rod 5.

[0064] Based on this, the first locking structure 6 includes a plurality of jacks 61, threaded holes 62 and locking bolts 63.

[0065] The plurality of jacks 61 are all opened on the support rod 5 and are arranged at intervals along the axial direction of the support rod 5.

[0066] The threaded hole 62 is opened on the slider 9 and is communicated with the guiding hole 91 and is adapted to be coaxially communicated with any one of the jacks 61.

[0067] The locking bolt 63 is threadedly connected with the threaded hole 62 and is adapted to be inserted into any one of the jacks 61 to limit the relative movement between the support rod 5 and the slider 9.

[0068] In some embodiments, as Figure 5 shown, the slider 9 has a protruding portion 92 extending outward, and the threaded hole 62 penetrates from the extending end surface of the protruding portion 92 to the inner peripheral surface of the guiding hole 91; due to the existence of the protruding portion 92, the axial length of the threaded hole 62 can be increased to ensure the connection strength between it and the locking bolt 63.

[0069] In some embodiments, as Figure 5 shown, a sinking groove 93 which is coaxially arranged with the threaded hole 62 and is adapted for the locking bolt 63 to be embedded is further opened on the inner wall of the guiding hole 91.

[0070] By adopting the above technical solution, when the locking bolt 63 abuts against the bottom of the sinking groove 93, the head of the locking bolt 63 abuts against the extending end surface of the protruding portion 92 to ensure the full cooperation between the locking bolt 63 and the support rod 5.

[0071] In some embodiments, as Figure 8As shown, the vertical rod 10 further includes a rotating member 101 which is rotatably connected to the upper end surface of the vertical rod 10 in the up and down direction, and a fixing ring 102 suitable for connecting with the end of the safety rope 20 is provided on the rotating member 101, so as to realize the inclined arrangement of the safety rope 20 relative to the width direction of the capping beam 100.

[0072] In some embodiments, as Figures 2 to 4 shown, anti-slip pads 8 for fitting with the stoppers 200 are provided on both the outer baffle 2 and the inner baffle 4; through the anti-slip pads 8, the friction coefficient of the contact surface can be enhanced to avoid accidents such as the separation of the connecting member from the stopper 200 and the dropping of the safety rope 20 caused by sliding.

[0073] The above content is only the preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
