Above-mentioned utility model though can effectively provide the supporting role to operating personnel, nevertheless in case bind the rope fracture problem that appears at solid fixed ring, then operating personnel will lose the safety guarantee, cause personnel loss of property.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a safe suspended structure is used in high altitude construction is built in room to solve the lower technical problem of suspended structure security.

In order to achieve the purpose, the utility model discloses a basic scheme provides a safe suspended structure is used in high altitude construction in room, including the wall body that is equipped with the preformed hole, the preformed hole interpolation has the bolt, bolt axial end fixing has solid fixed ring, gu fixed ring fixedly connected with owner safety rope, solid fixed ring one end threaded connection is kept away from to the bolt has the nut, bolt lateral wall circumferential direction is connected with the pulley, the pulley swivelling joint has vice safety rope, the coaxial fixed cover body that has on the bolt outer wall, cover body side wall is equipped with the opening, the opening inner wall articulates there is with opening complex dog, the articulated department of dog is equipped with the torsional spring, the torsional spring makes the closed opening of dog under free state, the dog.

The principle of the basic scheme is as follows: the bolt is inserted into the preformed hole and is screwed and fixed through the nut, and then the bolt plays a role in fixed support. The operating personnel's main safety rope one end is fixed on solid fixed ring, and the other end extends and passes the vice solid fixed ring on the dog and fix on operating personnel's health, and the torsional spring receives the extrusion dog to be in the open mode under operating personnel's action of gravity. Meanwhile, the auxiliary safety rope is connected to the pulley in a sliding mode, and one end of the auxiliary safety rope extends out of the opening and is fixed on the body of an operator.

Under the state of normal operation, main safety rope is in the state of tensioning, and vice safety rope is in free slip under the effect of pulley, can not cause the influence to operating personnel. When main safety rope fracture appeared, main safety rope can't continue to provide pulling force to the dog, and then makes the dog seal the conical cover opening under the torsional spring effect. The dog seals the opening and then will be located the vice safety rope of open-ended and presss from both sides tightly, and vice safety rope can't continue to slide, and then provides the pulling force to operating personnel and effectively avoids personnel to fall, finally reaches secondary protection operating personnel's technological effect.

The beneficial effect of this basic scheme lies in: compared with the prior art, the safe suspension structure of the technical scheme can provide safe support for operators and can also provide secondary protection for the operators, and the safety of high-altitude outdoor operation is effectively improved.

Furthermore, the reserved hole is internally connected with a fixed sleeve in an interference mode, the fixed sleeve is axially provided with an internal thread, and the internal thread of the fixed sleeve is in threaded connection with the bolt.

This technical scheme makes the bolt can be at preformed hole internal thread connection through addding fixed cover and then, avoids the bolt to skid in the preformed hole, strengthens the actual fixed effect of bolt.

Further, the outer wall of the fixed sleeve is provided with a rubber layer.

This technical scheme is through the mode of addding the rubber layer to increase the frictional force between fixed cover and the preformed hole, prevent that fixed cover from taking place to skid in the preformed hole. The elasticity of the rubber layer enables the fixing sleeve to be better matched with the reserved hole.

Further, the side wall of the pulley is in threaded connection with a screw, and the axial end part of the screw abuts against the surface of a wall body.

The screw passes the pulley and is fixed in the wall body surface, effectively increases the extrusion force between whole suspended structure and the wall body, and then increases safe suspended structure's static friction, avoids safe suspended structure not hard up problem to appear.

Furthermore, the side wall of the cover body is provided with a through hole for screwing a screw.

According to the technical scheme, the through hole is formed in the surface of the cover body, so that an operator can conveniently install or dismantle the screw on the premise of not moving the cover body.

Furthermore, a rubber ring is arranged at the end part of the screw close to the wall body.

This technical scheme has enlarged area of contact through addding the rubber circle on the one hand, avoids causing destruction to the wall body at extruded in-process screw stress concentration, and on the other hand rubber circle can provide bigger static friction power, improves safety suspension's stability.

Furthermore, a gasket is coaxially arranged between the nut and the wall body, and the inner diameter of the gasket is larger than the outer diameter of the bolt.

This technical scheme is through add the packing ring between nut and wall body, and then plays the cushioning effect, enlarges the lifting surface area of wall body, avoids indoor wall body to receive the damage.

Further, the axis of the gasket is provided with an annular convex block along the axial direction, and the outer diameter of the annular convex block is smaller than the inner diameter of the reserved hole.

The side of the gasket, which is provided with the convex block, can be directly inserted into the reserved hole in the installation process, so that the gasket and the bolt can be conveniently positioned in the installation process.

Furthermore, a plurality of ratchets are arranged on the end face of the stop block.

This technical scheme is through add the ratchet on the surface, and then increases the frictional force between dog and the vice safety rope, prevents to appear becoming flexible at the in-process that the dog presss from both sides tight vice safety rope.

Further, the cover body is a conical cover, the opening of the conical cover faces to one side close to the pulley, and the axial length of the conical cover is greater than the axial distance between the pulley and the conical cover.

The conical cover of the technical scheme can play a role in shielding and protecting the pulley, prolongs the service life of the pulley and the auxiliary safety rope, and improves the safety of the auxiliary safety rope.
