Abstract
The utility model belongs to the field of construction machinery and relates to a quick-locking type tower-crane-operator climbing safety device. The quick-locking type tower-crane-operator climbing safety device is mainly characterized in that a safety rope is connected with one end of a pulling cable, and a fixed hanging piece is arranged at the end of the pulling cable; the cable body of the pulling cable is connected with pulley blocks, and ratchet quick-locking brake is arranged on the movable pulley of each pulley block; the other end of the pulling cable is connected with a balancing weight which is matched with a tower crane. The quick-locking type tower-crane-operator climbing safety device has the advantage of reasonable structure and can ensure safety and labor saving of a tower crane operator in the climbing process.
Description
Technical field
The utility model belongs to vehicle for construction field, relates to tower machine accessory, is specifically related to a kind of fast locking-type tower machine work and climbs safety device.
Background technology
Existing tower machine for building, tower machine staff, in the process of upper and lower tower machine, generally adopts the mode of free-hand climbing tower ladder.Because tower machine is along with increasing of building raises, more than ten floors, in climbing, the impact that is subject to environment and self waits, the speed of not only climbing is slow, and exists major safety risks, once when accidentally dropping or slipping, can cause fatal accident to occur.
Summary of the invention
Contriver, in social practice, finds existing tower machine for building, and the mode of climbing tower ladder in the upper and lower process of staff, exists larger defect.Through exploring, improve, object is to provide a kind of fast locking-type tower machine work to climb safety device, can ensure the safety of tower machine staff in the process of upper and lower tower machine, and improve climbing speed.
The technical scheme that the utility model adopts is that a kind of fast locking-type tower machine work of design is climbed safety device, its structure comprises: safety strap, safety rope, safety rope is connected with one end of drawing rope, in this one end of drawing rope, be provided with the solid suspension member with tower ladder, the rope body of drawing rope respectively be laid in tower ladder on the fixed pulley of assembly pulley in squarer machine frame with movable pulley around being connected, at the other end of drawing rope, be provided with clump weight, on the movable pulley of assembly pulley, be provided with ratchet speed lock drg.
Described ratchet speed lock drg, structure comprises: be fixed on the shell in tower machine frame, on the wheel rim of the movable pulley of assembly pulley, be provided with ratchet, bottom, bearing frame two ends at movable pulley is provided with U-shaped pulling-on piece, in U-shaped pulling-on piece, be provided with Compress Spring, or be provided with extension spring under U-shaped pulling-on piece and between shell, above movable pulley, corresponding ratchet is fixed with slipper.
Described clump weight is spherical clump weight.
During use, before tower machine staff climbing tower ladder, by wearing safety belt with it, the jail that is connected with safety rope, departs from tower ladder by the solid suspension member of the tower ladder of drawing rope one end.Now, upwards climb, staff is in climbing, and human body raises, and clump weight can play power-assisted effect to upwards climbing action along with decline, after climbing on control position platform, first the solid suspension member of tower ladder and tower ladder are admittedly firmly linked with and are leaned on, then solution is removed safety strap; In climbing, along with human body declines, clump weight can increase downwards, and downward climbing action is played to the effect of dragging that helps; Spherical clump weight with human body lifting process in, spherical clump weight plays windproof, anti-beat effect, ratchet speed lock drg medi-spring elastic force or pulling force equate to coordinate to the application force of movable pulley with the gravity of clump weight, and the ratchet on movable pulley is always in critical conditions.
In climbing, accidentally drop or slip, first assembly pulley plays deceleration effort, when staff is in the situation that out of control, fall, descending speed increases suddenly, and safety rope pulling force increases, be greater than the application force of spring to movable pulley, break movable pulley critical conditions, movable pulley upward movement and brake shoes are collided, and reach anxious lock braking effect.After braking, human body is unsettled motionless, prevents that fallen accident from occurring.After dangerous releasing, safety rope is loosening, and under the cooperation of clump weight, spring pulls movable pulley brake off state, can continue to use, and with this, reaches repeatedly used effect.This fast locking-type tower machine work of the invention is climbed safety device, has rational in infrastructurely, can ensure that tower machine work is in climbing, safety, labour-saving remarkable advantage.

The specific embodiment
In conjunction with the accompanying drawings and embodiments, further illustrate the concrete structure that the invention speed locking-type tower machine work is climbed safety device.
The invention speed locking-type tower machine work is climbed the embodiment 1 of safety device, referring to Fig. 1, Fig. 2, its structure comprises: safety strap or Safety vest, safety rope (not shown), safety rope is fixedly connected with one end of drawing rope 2, be located at the solid suspension member 1 of this one end of drawing rope and tower ladder, the rope body of rope drag-line 2 respectively with the fixed pulley 4 that is arranged on the assembly pulley in squarer machine frame on tower ladder, 6 reel and are connected with movable pulley 5, the other end at drawing rope 2 is provided with clump weight 7, in order to prevent that clump weight 7 from swinging and being obstructed aloft, clump weight 7 is spherical clump weight, on the movable pulley 5 of assembly pulley, be provided with ratchet speed lock drg 3.Described ratchet speed lock drg 3 adopts: be fixed on the shell 3.2 in tower machine frame, the continuous ratchet 3.3 arranging on the wheel rim of movable pulley 5, the U-shaped pulling-on piece 3.4 arranging below the two ends of the bearing frame 5.1 of movable pulley, the Compress Spring 3.6 being provided with in U-shaped pulling-on piece and Compress Spring seat 3.5, above movable pulley, corresponding ratchet is fixed with slipper 3.1.
The utility model speed locking-type tower machine work is climbed the embodiment 2 of safety device, referring to 3, Fig. 4, its structure comprises: in the structure of embodiment 1, described ratchet speed lock drg 3 adopts: be fixed on the shell 3.2 in tower machine frame, the continuous ratchet 3.3 arranging on the wheel rim of movable pulley 5, the U-shaped pulling-on piece 3.4 arranging in the bottom, two ends of the bearing frame 5.1 of movable pulley, below U-shaped pulling-on piece 3.4 and between shell 3.2, take shell as spring perch 3.5, be provided with extension spring 3.6, above movable pulley, corresponding ratchet is fixed with slipper 3.1.
Model machine is through test, and performance normal operation, has realized the task of inventing.
