Falling tension fatigue test device for power construction safety belt

Abstract

The invention provides a falling tension fatigue test device for a power construction safety belt. The falling tension fatigue test device comprises slip rings, contact pins, track grooves, a slidinghanger plate, rollers, arc-shaped supporting plates and reclining grooves; the rear end of the rail groove is provided with an opening; two jacking plates are symmetrically supported at the exterior eaves of the rear ends of the left side wall and the right side wall of the rail groove; the length of the rail groove is half of the length of the sliding lifting plate; a rotary shaft penetrates through a bearing block in an inserted mode; the left end of the rotary shaft is sleeved with a sector gear with the diameter of 0.5 m in a locked mode; the right end of the rotary shaft is sleeved with agear in a locked mode; the gear is in transmission with a gear of a driving motor through a chain; and a photoelectric sensing switch is arranged on the surface, on one side of the bearing block, ofa mounting plate in a locked and supported mode through screws. According to the falling tension fatigue test device, the two sets of arc-shaped supporting plates are arranged, the two sets of arc-shaped supporting plates and the two reclining grooves in the two sets of arc-shaped supporting plates can be supported and combined to form two reclining frames, and the two reclining frames can simulate chest and abdomen skeletons of human bodies, so that the safety belt can be conveniently reclined and locked on the reclining frames.

Description

technical field [0001] The invention belongs to the technical fields of safety belt test device and electric equipment, and more specifically relates to a drop tension fatigue test device for safety belts in electric power construction. Background technique [0002] Seat belts are widely used in construction, electrical engineering, vehicles, high-altitude activities and other fields, and are important accessories to ensure personal safety. Therefore, the load-bearing capacity of seat belts is very important, and safety belts need to be tested for drop impact fatigue before leaving the factory. [0003] After searching, for example, the patent No. CN201620267354.7 discloses a safety belt buffer test device, which includes a test frame, a buffer to be tested connected with an iron man, a lifting device, a detection device, and a console; the lifting device includes Two chutes that are vertically arranged on both sides of the test frame and protrude from the upper end of the t...
