Description

Technical Field

[0001] This utility model relates to the field of construction safety protection, and in particular to a rotatable safety guardrail. Background Technology

[0002] For example, Chinese Utility Model Patent Publication No. CN 209339731 U discloses a construction safety railing, including a first support post, a connecting sleeve, a top protective cover, a fixed insert, movable wheels, an adjustable reflective warning sign structure, a multi-functional warning tape storage tube structure, a protective railing gate structure with storage space, a second support post, a reserved connecting ear plate, a fixed insert ring, a support rod, a rubber seat, a universal ball, a fixed ear plate, and a protective net. It rotates left and right, but cannot rotate up and down to level the railing. Utility Model Content

[0003] The purpose of this invention is to provide a rotatable safety guardrail that can rotate up and down, making it easy to lay the guardrail flat so that it can pass under the concrete slab during subsequent slipform operations.

[0004] To achieve the above objectives, a rotatable safety guardrail is employed, comprising:

[0005] The first corbel is installed at intervals on one side of the truss beam;

[0006] A flat board, which is laid on the corbel;

[0007] The railing is hinged at its lower side to the outer end of the corbel;

[0008] The first hinge support is fixed to the outside of the upright of the railing;

[0009] The connecting rod has its upper end hinged to the first hinge support;

[0010] The hydraulic jack is horizontally fixed to the side of the truss beam, located below the first corbel;

[0011] The second hinge support is fixed to the piston end of the hydraulic jack and hinged to the lower end of the connecting rod.

[0012] With this structure, the piston rod is retracted by a hydraulic jack, and the connecting rod rotates downward under the drive of the hydraulic jack, thereby causing the railing to rotate and thus level the railing.

[0013] As a further improvement of this utility model, the railing and the corbel are hinged together by a hinge joint, which includes a rotating joint and a fixed joint that share a common pin. The rotating joint is fixed to the lower side of the railing, and the fixed joint is fixed to the outer end of the corbel.

[0014] With this structure, the hinge energy-saving mechanism allows rotation between the railing and the corbel.

[0015] As a further improvement of this utility model, the connecting rod includes a first body and a second body, and a first spring is provided between the first body and the second body. One end of the first spring is fixed to the first body, and the other end is fixed to the second body.

[0016] This structure prevents the hydraulic jack from applying excessive force, which could damage the connecting rod. The first spring provides a buffering effect and also allows the connecting rod to extend and retract to accommodate changes in its length during rotation.

[0017] As a further improvement of this utility model, clamps are provided on the first body and the second body; limiting rods are slidably inserted at corresponding positions of the two clamps.

[0018] This structure prevents the connecting rod from bending.

[0019] As a further improvement of this utility model, limiting nuts are provided at both ends of the limiting rod, and a second spring is provided between the limiting nuts and the clamp.

[0020] With this structure, the limit rod has a reset function.

[0021] As a further improvement of this utility model, the railing end is hinged with an angle steel, which can be flipped between the railing and the first corbel, and one of its limbs faces the end face of the first corbel, and a pad is set between one limb of the angle steel and the end face of the first corbel.

[0022] This structure prevents the springs from pushing back against the railing, thus ensuring the railing remains stable.

[0023] As a further improvement of this utility model, a triangular reinforcing plate is provided between the two legs of the angle steel.

[0024] This structure is used to reinforce the angle steel.

[0025] As a further improvement of this utility model, a second bracket is installed below the hydraulic jack, and a reaction frame is provided on the second bracket to fix the hydraulic jack.

[0026] This structure is used to strengthen the fixation of the hydraulic jack.

[0027] This invention enables vertical rotation, facilitating the leveling of the railing so that it can pass underneath the concrete slab during subsequent slipform operations. Attached Figure Description

[0039] Example 1

[0040] like Figures 1-5 As shown, a rotatable safety guardrail includes:

[0041] The first corbel 1 is installed at intervals on one side of the truss beam 2;

[0042] Flat plate 3, which is laid on corbel 1;

[0043] The lower side of the railing 4 is hinged to the outer end of the corbel 1;

[0044] The first hinge support 5 is fixed to the outside of the upright of the railing 4;

[0055] In this embodiment, limiting nuts 606 are provided at both ends of the limiting rod 605, and a second spring 607 is provided between the limiting nuts 606 and the clamp.

[0056] With this structure, the limit rod 605 has a reset function.

[0057] In this embodiment, the railing 4 is hinged to an angle steel 10 at one end. The angle steel 10 can be flipped between the railing 4 and the first corbel 1, and one of its limbs faces the end face of the first corbel 1. A pad block 11 is provided between one limb of the angle steel 10 and the end face of the first corbel 1.

[0058] This structure prevents the spring from pushing back against the railing 4, thus ensuring that the railing 4 remains stable.

[0059] In this embodiment, a triangular reinforcing plate 12 is provided between the two limbs of the angle steel 10.

[0060] This structure is used to reinforce the angle steel 10.

[0061] In this embodiment, a second bracket 13 is installed below the hydraulic jack 7, and a reaction frame 14 is provided on the second bracket 13 to fix the hydraulic jack 7.

[0062] This structure is used to strengthen the fixation of the hydraulic jack 7.

[0063] This invention enables vertical rotation, facilitating the leveling of the railing so that it can pass underneath the concrete slab during subsequent slipform operations.
