Abstract
The utility model discloses a broken rope brake protector, comprising a hanging rod, hanging ring, a hanging rod seat, a lever, a braking wedge, a braking seat, and a spring, wherein, the hanging rod and the hanging ring are connected into one body, and the hanging ring is connected with a hanging cable; the hanging rod is fixed in the hanging rod seat through screw bolts, and the hanging rod seat is fixed at a bearing beam of a hanging cage; the hanging rod is connected with the braking wedge through the lever, and the braking wedge is wedged into the braking seat which is connected with the lever through the spring; a guide cable passes through the braking seat, one end of the guide cable is fixed at ground, and the other end is connected with a ceiling beam; the slope angle of the braking wedge and the guide cable of the hanging cage is from 10 DEG to 25 DEG; the surfaces of the braking wedge and the braking seat corresponding to the guide cable are jagged.
Description
The utility model relates to the fender guard of lifting means in a kind of building operation, specifically relates to the safety guard in the cage lifting process.
Cage also claims hanging basket, is a kind of lifting means that extensively adopts in building operation, mine and cableway.Realize the lifting of cage by lifting rope, in operational process, keep stable, the track that is made of angle steel and pulley is installed around general in order to make cage.Along with the rising of building, the also corresponding increase of the height of track.Its mounting process complexity, cost are higher.And,, generally adopt dragline to keep stable owing to be subjected to the restriction of objective condition for the field construction of bridge, mine one class, but, therefore can only be used for lifting means and material because it lacks effective safety precautions, must not be used for transporting of personnel.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of disconnected rope braking protector of cage is provided, and the safety that improves cage effectively reduces or avoid the generation of accident.
The purpose of this utility model is achieved in that it comprises suspension rod, suspension ring, gooseneck bracket, lever, scotch, Brake Block and spring; Suspension rod and suspension ring are connected as a single entity, and suspension ring are connected with lifting rope, and suspension rod is fixed by bolts in the gooseneck bracket, and gooseneck bracket is fixed by bolts on the bearing beam of cage; Be connected by lever between suspension rod and the scotch, in the scotch wedging Brake Block; Connect with spring between Brake Block and the lever, dragline passes Brake Block, and an end is fixed in ground, and the other end is connected with a day beam.
The purpose of this utility model can also realize by following measure: the angle of chamfer between the soft dragline of scotch and cage is 10 °～25 °, and the face of the corresponding dragline of scotch and Brake Block is a zig-zag.
Dragline of the present utility model can adopt cable wire, and also available other has certain intensity and fastness to rubbing, can bear all kinds of ropes of cage and contained Item Weight.
The utility model makes safety of construction improve greatly owing to adopt disconnected rope braking protector to come cage is carried out anti-falling protection.Therefore it is with low cost and mounting process is easy, suits to promote the use of in building engineering, and suitable especially benefit is used in the abominable field construction of communications and transportation difficulty, execution conditions.
Elaborate below in conjunction with drawings and Examples, but content of the present utility model is not limited to shown in the accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
The running condition figure of the present utility model that Fig. 2 is.
Fig. 2 has shown and in the construction of cast concrete bridge pier service condition of the present utility model has been installed on the cage.As can be seen, the broken rope protector 12 according to the utility model proposes comprises suspension rod 4, gooseneck bracket 3, lever 10, scotch 9, Brake Block 8 and spring 6 from Fig. 1 and Fig. 2; Suspension rod 4 is connected as a single entity with suspension ring 2, and suspension ring 2 are connected with lifting rope 1, and suspension rod 4 is fixed by bolts in the gooseneck bracket 3, and gooseneck bracket 3 is fixed by bolts on the bearing beam 5 of cage 13; Be connected by lever 10 between suspension rod 4 and the scotch 9, in the scotch 9 wedging Brake Blocks 8; Connect with spring between Brake Block 8 and the lever 10, dragline 7 passes Brake Block 8; One end of dragline 7 is fixed in ground, and the other end is connected with a day beam 11.
Usually, the upwards tractive force P of lifting rope 1 drives cage bearing beams 5 by the suspension rod 4 that is connected as a single entity with suspension ring 2, makes cage 13 rise or descend.Under the normal circumstances, suspension rod 4 slides into position topmost in gooseneck bracket 3, drive bearing beam 5.At this moment, scotch 9 is glided along the inclined-plane and be in the utmost point lower end of Brake Block 8 by lever 10, drg 12 is in open configuration, and the dragline 7 of cage 13 can be free movable in drg.When lifting rope 1 ruptures suddenly, suspension rod 3 loses when upper pulling force P, the utmost point lower end that the former spring that is tensioned 6 is moved suspension rod 4 to gooseneck bracket 3 by lever 10, scotch 9 is also pulled to by spring 6 simultaneously, in the wedging Brake Block 8, and on the inclined-plane compressing presses down to dragline 7.The angle of chamfer of scotch 9 and Brake Block 8, because of the friction material difference of selecting for use, selected in 10 °～25 ° scopes.Because of the oblique angle less than the friction angle between the dragline that has added lubricating oil, during scotch 9 wedging Brake Blocks 8, and 7 of draglines are irreversible impaction state, and the friction force that final moment produces is greater than tenesmus gravity, make cage 13 firmly be braked relevant position, prevent cage 13 to fall reliably at dragline 7.In order to increase the snap-in force with dragline 7, scotch 9 and Brake Block 8 and dragline 7 cooresponding surfaces should be processed indentation.
Claims (3)
1, a kind of disconnected rope braking protector is characterized in that comprising suspension rod, suspension ring, gooseneck bracket, lever, scotch, Brake Block and spring; Suspension rod and suspension ring are connected as a single entity, and suspension ring are connected with lifting rope, and suspension rod is fixed by bolts in the gooseneck bracket, and gooseneck bracket is fixed by bolts on the bearing beam of cage; Be connected by lever between suspension rod and the scotch, in the scotch wedging Brake Block; Connect with spring between Brake Block and the lever, dragline passes Brake Block, and an end is fixed in ground, and the other end is connected with a day beam.
2, disconnected rope braking protector according to claim 1 is characterized in that the angle of chamfer between described scotch and cage dragline is 10 °～25 °.
