Detailed Description

The life rope hanging device is used for being fixedly arranged on other fixed objects, hanging the life rope through the two hooks, avoiding excessive sagging of the life rope, taking the fixed object as I-steel as an example, and further describing the utility model with reference to the attached drawings.

As shown in fig. 1, the life rope hanging device comprises a first clamp body and a second clamp body, the first clamp body and the second clamp body are identical in structure, the upper parts of the first clamp body and the second clamp body are fixing parts, clamping grooves are respectively formed in the two fixing parts, two ends of the clamping grooves are communicated, and openings of the two clamping grooves are oppositely arranged. The clamping groove is used for clamping in the flange plate of the I-steel 6, so that two ends of the clamping groove are communicated. The first clamp body and the second clamp body are clamped in from two sides of the I-steel 6, so that openings of the two clamping grooves are oppositely arranged. The lower parts of the first clamp body and the second clamp body are respectively provided with a hanging part 4, the two hanging parts 4 are respectively provided with a connecting hole, the first clamp body and the second clamp body are fixed by opposite pulling through connecting rods 5 penetrating through the connecting holes, and the first clamp body and the second clamp body are prevented from slipping off I-steel 6. The connecting rod 5 can be a bolt with a nut, so that the cost is low and the installation is convenient. The two hanging parts 4 are also respectively provided with a hook, the opening directions of the two hooks are opposite, so that the life rope can conveniently pass through the hooks, and the life rope can be prevented from sliding out of the hooks, for example, the two hooks are both C-shaped. The two hanging parts 4 are provided with a gap, so that a life rope can be conveniently put into the two hooks, and more importantly, the hanging buckle of the safety belt can firstly enter the gap between the two hanging parts 4 from one hook and then pass out from the other hook under the condition that the safety belt is not taken out from the life rope. Therefore, the gap between the two hanging parts 4 needs to be wider than the size of the hanging buckle of the safety belt, so that the problem that the hanging buckle of the safety belt is blocked in the gap between the two hanging parts 4 and cannot pass through is avoided; at the same time, the problem of too little restriction of the safety line due to too wide a gap between the two suspension parts 4 is also avoided.

The clamping groove of the fixing part is formed by a plate, for example, the clamping groove is formed by fixedly connecting an upper clamping plate 1, a side plate 2 and a lower clamping plate 3, or the upper clamping plate 1, the side plate 2 and the lower clamping plate 3 are integrated; the hanging part 4 is of a plate-shaped structure and is fixedly connected to one side of the lower clamping plate 3 opposite to the upper clamping plate 1, or the fixing part and the hanging part 4 are integrated. Based on the consideration of material strength, cost and convenience, the upper clamping plate 1, the side plates 2, the lower clamping plate 3 and the hanging part 4 are all steel plates, and the steel plates are welded and connected or integrally bent. The corresponding planes of the two hanging parts 4 are parallel to each other and perpendicular to the corresponding planes of the two clamping grooves, and the stress of the first clamp body and the stress of the second clamp body are the same. The width of the clamping groove is determined according to the thickness of the flange plate, so that the flange plate can be clamped into the clamping groove; the depth of the clamping groove is determined according to the width of the flange plate so as to enlarge the contact area between the upper clamping plate 1 and the flange plate. In order to ensure a gap of sufficient width between the two hanging parts 4, the side plates 2 and the hanging parts 4 are connected to opposite sides of the lower card 3, and the width of the upper card 1 is greater than that of the lower card 3.

Welding is often needed in steel construction, and in order to avoid life rope linkage to pass electricity, insulating pads are arranged inside clamping grooves of the first clamp body and the second clamp body. For example, the insulating pad is a rubber pad. The insulating pad also has a protective effect and prevents the clamping groove from damaging the flange plate in the stress process.
