Abstract
The invention belongs to the field of building machinery, and relates to a tower crane worker climbing safety device. The tower crane worker climbing safety device has the main characteristics that a safety rope is connected with one end of a tractive cable; the end of the tractive cable, connected with the safety rope, is provided with a fixing and hanging element; a body of the tractive cable is respectively connected with fixed pulley groups; fixed pulleys are provided with brakes; emergent brakes are adopted as the brakes; and the other end of the tractive rope is connected with a balancing weight which is installed on a tower crane in a matching way. The tower crane worker climbing safety device has the advantages of reasonable structure, and capabilities of guaranteeing safety, labor conservation and acceleration during the climbing process for tower crane workers.
Description
Technical field
The invention belongs to the vehicle for construction field, relates to tower machine accessory, is specifically related to a kind of tower machine worker and climbs safety device.
Background technology
Existing tower machine for building, tower machine staff generally adopts the mode of free-hand climbing tower ladder in the process of tower machine up and down.Owing to the tower machine along with increasing of building raises, more than ten floors, in climbing, the influence that waited by environment and self, the speed of not only climbing is slow, and exists major safety risks, when in case accidentally drop or slip, can cause fatal accident to take place.
Summary of the invention
The contriver finds existing tower machine for building in social practice, the mode of climbing tower ladder in the process about the staff exists big defective.Through explore improving, purpose is to provide a kind of tower machine worker to climb safety device, can ensure tower machine staff in the process safe of tower machine up and down, and improve climbing speed.
The technical scheme that the invention is adopted is that a kind of tower machine worker of design climbs safety device, its structure comprises: safety strap, safety rope, wherein safety rope is connected with an end of drawing rope, be provided with solid suspension member with the tower ladder at this end of drawing rope, the rope body of drawing rope respectively be laid in the tower ladder on fixed pulley group on the squarer machine frame be connected, be provided with drg at fixed pulley, the other end at drawing rope is provided with clump weight, also is provided with the protection cage outside clump weight.
In said structure, described drg adopts accident brake, its structure comprises: be fixed on the shell on the frame, be located at the disk on the fixed pulley axis, medial surface at disk is provided with centrifugal hook more than, the body of rod at centrifugal hook is provided with extension spring, is provided with positive stop at the rear of centrifugal hook pin axle, is provided with inside the shell and the corresponding draw-in groove of centrifugal hook.
Described protection cage is spherical.
During use, before tower machine staff climbing tower ladder, with wearing safety belt on one's body, the jail that links to each other with safety rope breaks away from the tower ladder with the solid suspension member of tower ladder of drawing rope one end.At this moment, upwards climb, the staff is in climbing, and human body raises, and clump weight can play the power-assisted effect to upwards climbing action along with decline, and after climbing on the control position platform, it is firm earlier the solid suspension member of tower ladder and tower ladder to be hung admittedly, and solution is removed safety strap again; Downwards in the climbing, along with human body descends, clump weight can increase, and the effect of dragging that helps is played in downward climbing action, clump weight with the human body lifting process in, the protection cage plays windproof, anti-beat effect; In climbing, accidentally drop or slip, the fixed pulley group at first plays deceleration effort, when the staff under situation out of control, fall, the fixed pulley fast rotational, the disk of accident brake can be with the fixed pulley axis fast rotational, and the centrifugal hook on the disk can open automatically, snaps in the draw-in groove on the shell, fixed pulley is played the emergency braking effect, guarantee staff's safety, loosen drawing rope, accident brake can be released braking.
In a word, this tower machine worker of the invention climbs safety device, has rational in infrastructurely, can ensure tower machine worker in climbing, and is safe, laborsaving, the remarkable advantage of quickening.
