Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of safety protection, more particularly to a safety belt suspension device and static load testing device thereof. BACKGROUND
[0002] The safety belt suspension device is also called an inspection platform, and its main function is to suspend a safety belt or a fall arrestor during aerial work to avoid the falling of construction personnel and threaten personal safety.
[0003] The existing safety belt suspension device is generally composed of a locking device and a suspension rod, and the locking device usually wraps around an I-beam. In order to fix the locking device, a pressing plate is usually added to the upper and lower flange plates of the I-beam through screwing to press the flange plates. However, in actual aerial work, the suspension rod not only bears the vertical pressure exerted by the human body, but also bears the horizontal tensile force component. At this time, the pressing plate is prone to looseness, which leads to the clamping height inside the locking device being greater than the actual height of the I-beam, thereby causing safety risks. Moreover, the specifications of the existing locking device lack flexible adjustment according to the size of the I-beam.
[0004] In addition, the existing static load testing device for the safety belt suspension device usually combines an electric push rod and a weight. The electric push rod is extended, a connecting rope is connected to the suspension point and the electric push rod, the electric push rod is retracted, and the weight is lifted to the test height to detect the static load of the inspection platform. When the electric push rod of the static load testing device is retracted, the weight is suspended. Due to the angle between the connecting rope and the rod, the composite insulating rod is affected by the eccentric load, and the weight is prone to left-right swinging displacement, thereby affecting the test effect and failing to meet the requirements of the national standard.
