Abstract
A safety belt hanger relates to safety devices. The safety belt hanger is provided with a connecting rod, which has one end provided with a forward oblique hook lever provided thereon with a hook head having the opening facing back inferior, and the other end provided with a backward oblique hook lever provided thereon with a hook head having the opening facing front inferior. The connecting line of the centers of the two hook heads is parallel with the connecting rod. In application, only the connecting rod is required to be forward and reversely rotated, the safety belt hanger integrally jumps over a connecting plate connecting a safety rope. The two hook heads do not depart from the safety rope all along during the operational process, even if an accident occurs when the safety belt hanger is controlled to jump over the connecting plate and the safety belt hanger is out of control in a flash. The two hook head have different opening directions, and two hook levers form a certain included angle therebetween, so that the chance that two hood heads of the safety belt hanger depart from the safety rope simultaneously is almost zero, and working personnel is constantly under safety protection during whole processing of working on a tower erecting arm, thereby providing high safety.
Description
Technical field
The utility model relates to the safety device of work high above the ground, says it is the safety belt hook that a kind of service tower machine crane arm is used in detail.
Background technology
We know that tower machine crane arm is the part of the force that is used for promoting, transporting weight, in use need often maintenance or dismounting outfit.Because tower machine crane arm is generally higher apart from ground; Relevant above that operation belongs to work high above the ground, and personal safety protection is extremely important, and safety device is on tower machine crane arm top boom, to be uniformly distributed with several Connection Blocks on the existing tower machine crane arm; Connection Block is provided with connecting plate; The connecting plate leading section is provided with the safety rope hole, and safety rope is equipped with safety rope in the hole, and the two ends of safety rope are fixed on the two ends of tower machine crane arm.The staff overhauls tower machine crane arm or during the attached workpiece of dismounting, on health, dresses safety belt, and the safety belt front end is provided with safety door hook; After climbing up tower machine crane arm; Safety door hook is hung on the safety rope, and in the course of the work, the staff is when falling because of tower machine crane arm rocks, slide in astasia or underfooting, step on reason such as sky; Safety belt can in time be held the staff, avoids the generation accident.But existing safety door hook is single hook; When the staff walks to the connecting plate place, need safety door hook be taken, hang on the safety rope of connecting plate opposite side, the hook take to hang up once more safety rope during in; Staff's personal safety has broken away from protection, poor stability.
Summary of the invention
The purpose of the utility model is the deficiency that solves above-mentioned prior art, does not break away from safeguard protection constantly in the whole process that provides a kind of staff on tower machine crane arm, to work, safe safety belt hook.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of safety belt hook; It is characterized in that being provided with connecting rod; Connecting rod one end is provided with the neck of hook that turns forward, and the neck of hook that turns forward is provided with the gib head of opening towards the back lower place, and the connecting rod other end is provided with the sweptback neck of hook; The sweptback neck of hook is provided with the gib head of opening towards the front lower place, and the line of centres of two gib heads is parallel with connecting rod.
Angle between the neck of hook that turns forward in the utility model and the sweptback neck of hook is between 20 °-60 °.
The staff overhauls tower machine crane arm or during the attached workpiece of dismounting; On health, dress safety belt, the utility model be installed in the safety belt front end, climb up tower machine crane arm after; Two gib heads are hung on the safety rope; When the staff walked to the connecting plate place, the bar that only need be rotationally connected was linked up with the back gib head opening in the place ahead and connecting plate relatively to the front slide safety belt, the gib head in the place ahead connecting plate of just jumping over smoothly; The back is to front slide safety belt hook relatively for the backward rotation connecting rod gib head opening and the connecting plate that make the rear then, and safety belt is linked up with just the integral body connecting plate of jumping over.Two gib heads do not break away from safety rope all the time in the operating process; It is out of control to make safety belt link up with moment even when control safety belt hook is jumped over connecting plate, have unexpectedly incident; Because the opening direction of two gib heads is different, has certain included angle between two necks of hook, the probability that two gib heads of safety belt hook break away from safety rope simultaneously is almost nil; Constantly do not break away from safeguard protection in the whole process that the staff works on tower machine crane arm, safe.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the perspective view of the utility model.
The specific embodiment
A kind of safety belt hook as shown in the figure; Be provided with connecting rod 3; Connecting rod 3 one ends are provided with the neck of hook 2 that turns forward, and the neck of hook 2 that turns forward is provided with the gib head 1 of opening towards the back lower place, and the connecting rod other end is provided with the sweptback neck of hook 4; The sweptback neck of hook 4 is provided with the gib head 5 of opening towards the front lower place; Angle between the neck of hook that turns forward and the sweptback neck of hook facts have proved that between 20 °-60 ° the result of use in the time of 45 ° of the angle between the neck of hook that turns forward and the sweptback neck of hook is best.The line of centres of two gib heads is parallel with connecting rod.The staff overhauls tower machine crane arm or during the attached workpiece of dismounting; On health, dress safety belt, the utility model be installed in the safety belt front end, climb up tower machine crane arm after; Two gib heads are hung on the safety rope; When the staff walked to the connecting plate place, the bar that only need be rotationally connected was linked up with the back gib head opening in the place ahead and connecting plate relatively to the front slide safety belt, the gib head in the place ahead connecting plate of just jumping over smoothly; The back is to front slide safety belt hook relatively for the backward rotation connecting rod gib head opening and the connecting plate that make the rear then, and safety belt is linked up with just the integral body connecting plate of jumping over.Two gib heads do not break away from safety rope all the time in the operating process; It is out of control to make safety belt link up with moment even when control safety belt hook is jumped over connecting plate, have unexpectedly incident; Because the opening direction of two gib heads is different, has certain included angle between two necks of hook, the probability that two gib heads of safety belt hook break away from safety rope simultaneously is almost nil; Constantly do not break away from safeguard protection in the whole process that the staff works on tower machine crane arm, safe.
