The invention relates to a safety guardrail of a bridge crane. The safety guardrail comprises a base, a stand column and a transverse rod. One end of the transverse rod is hinged to the side portion of the stand column. The safety guardrail is installed on the side portion of the rail in the length direction of the rail, in the protection state, the guardrail body is unfolded, namely, the stand columns are vertically arranged, the transverse rods are transversely arranged on the side portions of the stand columns, and therefore the safety guardrail can provide safety protection for workers walking on the rail, and the nervous and anxious mood of the workers when the workers do not have the safety guardrail is eliminated. When the crane body walks on the track, the crane body pushes the stand column to rotate towards the front of the walking direction of the crane body, and meanwhile the fourth end rotates towards the direction close to the stand column, so that the guardrail body is switched from the unfolded state to the folded state, and in the folded state, the stand column is folded to the side portion of the base. And the second ends of the stand columns are lower than the bottom of the crane body, so that the height of the guardrail body can be reduced, and the crane body can conveniently pass through the track.

    本申请涉及一种桥式起重机的安全护栏。安全护栏包括底座、立柱及横杆。立柱的一端铰接于底座,横杆的一端铰接于立柱的侧部。安全护栏安装在轨道沿其长度方向的侧部,在防护状态下,护栏本体展开,即立柱竖向设置,横杆横向设于立柱的侧部,这样安全护栏可为在轨道上行走的工作人员提供安全防护,消除工作人员面对无安全护栏时紧张焦虑的情绪。当起重机本体在轨道上行走时,起重机本体推动立柱朝起重机本体行走方向的前方转动,同时第四端朝靠近立柱的方向转动,使得护栏本体从展开状态切换为收折状态,在收折状态下,立柱收折于底座的侧部,且立柱的第二端低于起重机本体的底部,如此可降低护栏本体的高度,以便起重机本体在轨道上通行。
