Description
Technical field
The utility model relates to a kind of helping and climbs safety device, relates in particular to a kind of safety device that helps tower crane working climbing building tower crane and prevent landing, belongs to Construction Safety technical field.
Background technology
Building tower crane is a kind of weight-lifting equipment the most frequently used on building ground, and common tower crane operative employee will climb up from ground the handling of tower top operational tower and turn, thereby this is an aloft work and is with dangerous work.Existing tower crane lacks the facility of protection tower crane operative employee person safety; climbing to the process of tower top especially, tower crane operative employee not only expends muscle power, and the safety factor of free-hand climbing is lower; just in case ascending stair corrosion or tower crane working are short of physical strength, hardly imaginable serious consequence will be caused.Therefore, existing building tower crane should improve operative employee's service conditions, and the protection facility that tightens security, and to strengthen safety factor, the accident that prevents is in possible trouble.
Summary of the invention
For the free-hand climbing building tower crane of tower crane operative employee, not only expend muscle power and also may cause the present situation of potential safety hazard, the utility model provides a kind of building tower crane to help and climbs safety device, makes tower crane operative employee climb easily and reach the object of security insurance.
The utility model Bian gets following technical scheme and implements: a kind of building tower crane helps climbs safety device, comprise ascending stair, two pulleys, a safety rope, a setting fastening rope, two safety catchs and a clump weight, ascending stair is vertically set on a side of building tower crane tower body inside, it is characterized in that:
Two described pulleys are bearing on the tower stature on top, ascending stair top by axis of revolution respectively, and the radial central planes of two pulleys coincidence vertical with ascending stair cross bar;
Described keeper sling is in the groove of two pulleys, and its one end connects clump weight, and the other end connects setting fastening rope middle part;
The two ends of described setting fastening rope are respectively equipped with safety catch, the safety strap that wherein safety catch can have with the tower crane operative employee waist system knot that interlocks, another safety catch can with the ascending stair cross bar knot that interlocks;
Described clump weight weight is less than tower crane operative employee body weight, and under off working state, by a safety catch on setting fastening rope, buckles knot ascending stair bottom bar and be suspended in pulley bottom;
Effective usable length sum of described safety rope and setting fastening rope meets tower crane operative employee to be fastened safety catch and climbs ascending stair top, the condition that clump weight lands simultaneously;
Described safety rope connects one end of setting fastening rope under natural suspension status, parallel with ascending stair, and is positioned at the plane of symmetry of ascending stair two columns, and and ascending stair on cross bar vertical distance be arranged between 30cm～50cm.
Technique scheme has following useful contribution:
1, tower crane operative employee fastens the safety rope in the utility model, and under the Action of Gravity Field of safety rope other end clump weight, climbs easily, moves freely;
Even if 2 tower crane operative employees' four limbs depart from ascending stair completely, health also can only slowly fall, and will never cause any personal injury.
The utlity model has simple in structure, easy to use, with low cost, help and climb advantage effective and that safety factor is high.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In accompanying drawing 1: 1 tower body, 2 and 3 pulleys, 4 clump weights, 5 and 6 safety catchs, 7 setting fastening ropes, 8 safety ropes, 9 ascending stairs.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further explained to explanation:
As shown in Figure 1, ascending stair 9 is vertically set on a side of building tower crane tower body 1 inside; Pulley 2 and 3 is bearing on the frame of ascending stair 9 top, top tower bodies 1 by axis of revolution respectively, and pulley 2 overlaps with 3 radial central planes and vertical with the cross bar on ascending stair 9; Safety rope 8 is looped around in the groove of two pulleys 2 and 3, and its one end connects clump weight 4, and the other end connects the middle part of setting fastening rope 7; The two ends of setting fastening rope 7 are respectively equipped with safety catch 5 and 6, the safety strap that wherein safety catch 5 can have with the tower crane operative employee waist system knot that interlocks, safety catch 6 can with ascending stair 9 on the cross bar knot that interlocks; Clump weight 4 weight are less than tower crane operative employee's the about 10kg of body weight, and the cross bar of buckleing knot ascending stair 9 bottoms by the safety catch 6 on setting fastening rope 7 under off working state is suspended in the bottom of pulley 3; Effective usable length sum of safety rope 8 and setting fastening rope 7 meets tower crane operative employee and fastens safety catch 5 climbings to the top of ascending stair 9, the condition that clump weight 4 just in time lands simultaneously; Safety rope 8 connects one end of setting fastening ropes 7 under natural suspension status, parallel with ascending stair 9, and is positioned at the plane of symmetry of 9 liang of columns of ascending stair, and and ascending stair 9 on cross bar vertical distance be arranged between 30cm～50cm.
Tower crane operative employee is before climbing ascending stair 9, first fasten the safety strap of waist, then safety catch 5 buttons are tied on safety strap, and unload button and tie the safety catch 6 on ascending stair 8 bottom bars, now one end of safety rope 8 is being suspended clump weight 4 in midair, and one end connects tower crane operative employee's body weight, because clump weight 4 weight in the utility model are less than tower crane operative employee's body weight, therefore tower crane operative employee has the trend being raised, and the displacement not being raised; When tower crane operative employee climbs into ascending stair 9, also constantly impose the power of about 10kg, tower crane operative employee just can climb the top of ascending stair 9 easily, and clump weight 4 arrives ground simultaneously; Unload safety catch 5, and by the upper cross bar of safety catch 6 button knot ascending stairs 9, thereby tower crane operative employee's climbing process completed.In climbing process, just in case the careless landing of tower crane operative employee, its health is also under the inclined to one side Action of Gravity Field of safety rope 8 other end clump weights 4, and slow decreasing, not only there will not be personal injury accident, and heavy climbing ladder 9 at any time, continues climbing to top.
