Abstract

The utility model discloses a life preserver, comprising a wire rope, a clamper, a safety belt, etc. The clamper is made of the metals, and the shape is similar to the shape of the pliers; the upper side of the handle of the pliers is provided with a controller composed of screws and nuts with the handles; the lower end of the handle of the pliers is provided with a loop for hanging the heavy objects; the safety belt is made of the canvas, is provided with a metal hooks with the reeds and can be connected with the hanging ring of the holder.

Description

life preserver used for high building construction

The utility model belongs to lifesaving appliance.

From TV news, see the performance of being external skyscraper buoyant apparatus.From outside watch, brucker survival capsule is square can, has a crank.The people who ties up on the brucker survival capsule shakes crank, and the rope that ties up on the skyscraper just extends out from the brucker survival capsule box, and the people promptly descends from eminence thereupon.The mechanism of similar capstan winch one class may be housed in the box according to one's analysis.The rope dish has worm gear on the cylinder on cylinder, crank has worm screw, and meshes with worm gear.Because worm gear and worm screw have self-locking action, when not shaking crank, the people can be parked in the air.This brucker survival capsule only limits a people to use, and decrease speed is slower, and in the time will passing through flame zone in the way that descends, the people might be burnt.

The purpose of this utility model is that the occupant for hotel, restaurant, hostel, office building, school, dormitory contour level building provides simple and easy, convenient, reliable, practical buoyant apparatus.

Fig. 1 is the schematic diagram of brucker survival capsule clamper.Fig. 2 is the A-A profile of brucker survival capsule clamper.Fig. 3 is the schematic diagram of part in the accompanying drawing 1 (1).Fig. 4 is the schematic diagram of part in the accompanying drawing 1 (7).Fig. 5 is the schematic diagram of part in the accompanying drawing 1 (2).Fig. 6 is the schematic diagram of part in the accompanying drawing 1 (5).Fig. 7 is the schematic diagram of safety belt and straphanger.

This life preserver used for high building construction (with reference to the accompanying drawings) is made up of steel wire rope (part in the accompanying drawing 1 (13)), clamper (accompanying drawing 1) and safety belt and straphanger (accompanying drawing 7) etc. Clamper is made with metal material, the similar pliers of its shape. Jaw inboard at clamper has the cross section relatively Approximate half-circular or leg-of-mutton groove are in order to the clamping steel wire rope. At the jaw upper and lower guider (7) is housed, can makes steel wire rope pass through smoothly jaw. On two clamp handles of clamper, respectively open a hole, run through a screw (3) in the middle of two holes. The end of thread at screw is equipped with a nut with handle (9). Screw, nut contact with clamp handle by packing ring (2), (12). The contact-making surface of packing ring and clamp handle is the garden cylinder, and they can be along garden Zhou Fangxiang relative sliding. Packing ring (2) all has boss with clamp handle and screw head contact jaw, can stop screw and packing ring to rotate. A Compress Spring (5) is housed between two clamp handles. At the screw external part with the nut of handle a protective cover (10) is housed. Ring or hook that the lower end of two clamp handles has the extension weight to use. Safety belt is made with canvas, the safety belt that resemble construction workers is used. Be equipped with on the safety belt with the metal card of spring leaf and angle, can be connected with the ring of clamper clamp handle lower end extension weight. Straphanger is made with woven belt or rope, and angle with becket and card at two ends. Steel wire rope one end has ring set or card to angle, and can tie up to firmly on the fixing point.

This brucker survival capsule is the weight of coming balance human body and belongings by the frictional force that the clamp holder clamping steel wire rope produces, by the clamping force of the change of the joystick on the swing holder, realize that people and belongings descend along steel wire rope with suitable speed with clamper to steel wire rope.

This brucker survival capsule is compared with the brucker survival capsule of seeing in TV news, has the following advantages:

(1) this brucker survival capsule steel cable can use for many people, and a clamper can use for two people simultaneously.If single use clamper, 100 jin of article of portability.

(2) use this brucker survival capsule fast speeds to pass through flame zone.

(3) this brucker survival capsule is simple in structure, and is easy to use.Steel cable can a plurality of clampers of adapted.Clamper can press from both sides steel wire rope easily or unload from steel wire rope.

(4) between the suspension ring hole of these brucker survival capsule two pincers handles a suitable distance is arranged.After hanging weight, the moment that is caused by gravity can make the clamp holder clamping steel wire rope.The clamping force that produces by this moment cause along the frictional force of steel wire rope direction just with the balanced of hanger, can realize self-locking.Like this, even when joystick is malfunctioning, the still available clencher handle safe falling of holding of people.

Realize that best way of the present utility model is the product of making shown in Figure of description.

In (accompanying drawing 1): 1. clamper caliper left side, 2. the cylinder packing ring, 3. square head screw, 4. cup packing, 5. spindle compression spring, 6. a pincers eye rivet, 7. guider, (8) caliper right-hand part, 9. with the nut of handle, 10. protective cover, (11) plain washer, (12) cylinder packing ring, (13) steel wire rope.

8. 1. the clamper caliper made with the 45# steel, nip part heat treatment hardness HRC～45～50.6. pincers eye rivet is made with the 35# steel.7. guider uses A ₃Steel plate is made.Square head screw 3., the band handle nut 9. make heat treatment hardness HRC30～40 with the 35# steel.Cylinder packing ring (2), (12), plain washer (11) is made with the 35# steel.5. spindle compression spring is shaped with the 60Si2Mn spring steel wire coiling of 3 millimeters of diameters, freely grows 75 millimeters, 28 millimeters in big-and-middle footpath, and the footpath is 20 millimeters in the minimum, number of total coils 9.5, number of

active coils

8,9 millimeters of pitches.4. cup packing uses A ₃The steel plate press forming.Protective cover plastics casting forming.

The steel wire rope model is 3.8 millimeters in a 6 * 7-3.8-170-I-light-left side (GB1102-74) rope footpath, nominal tensile strength 170kg/mm ²Its length is decided on depth of building.Steel wire rope one end is made a rope sling.
