Abstract
The utility model provides a safety arrangement that falls is prevented to tower crane from top to bottom, includes that automatic contraction type prevents falling stopper (1), can be fixed in the guide rope (12) preventing falling on the stopper lower extreme couple (9), wearable area location waistband (13) and the safety belt of braces (15) in on one's body, joins in marriage link (16) adorned on the safety belt braces. The utility model discloses can eliminate the potential safety hazard of falling that tower crane operating personnel exists at upper and lower tower crane in -process effectively, reduced safety accident's emergence, and dress conveniently, and can have enough to meet the need the use many times, save construction cost.
Description
Technical field
This utility model relates to safety protection device for building construction technical field.
Background technology
Building engineering construction scene tower crane operator upper and lower tower crane climbing at present is the highest, does not the most take protection to arrange during upper and lower tower crane
Execute, exist step on sliding, step on sky, grab the uncertain factors such as sliding, the factors such as rainy day, stair were wet and slippery, stair icing in winter add tower crane operator and fall
Risk, there are major safety risks.
Summary of the invention
This utility model purpose aims to provide one can be prevented effectively from tower crane operator's falling risk, and the convenient and practical anti-falling safe of tower crane up and down is protected
Protection unit.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of tower crane anti-falling safe protection device up and down, including automatic contractive falling-down prevention brake, is securable to falling-down prevention brake lower end hook
On strop, wearable in band positioning belt with it and the seat belt of braces, be fitted to the link on seat belt braces.
This utility model may also include can be by the steel O type mousing-hook together with seat belt link fastener of the falling-down prevention brake lower end hook.Described can
Seat belt with being worn on is also with two bottom bands of trouser legs.The length of described strop is not less than 30 meters.
Using this utility model, seat belt, when upper and lower tower crane, can be worn by tower crane operator, and automatic contractive falling-down prevention brake is solid
It is scheduled on operating board top, the lower end of automatic contractive falling-down prevention brake is hooked on the hanging point of seat belt, it is achieved to tower crane operator up and down
Security protection during tower crane.What this utility model was arranged is securable to the strop on the hook of falling-down prevention brake lower end, it is simple to ground staff will be fixed on
The highest automatic contractive falling-down prevention brake in position at tower crane operating board is left behind and is hooked on seat belt lower end.
This utility model can make in canalization, dismounts and wearing is quite convenient to, can repeatedly use, cost-effective.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of automatic contractive falling-down prevention brake of the present utility model；
Fig. 2 is the schematic diagram of seat belt.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment.
This utility model includes the automatic contractive falling-down prevention brake 1 shown in Fig. 1, the guiding being securable on falling-down prevention brake lower end hook 9
Rope 12, wearable in band positioning belt 13 with it and the seat belt of braces 15 shown in Fig. 2, the link 16 being fitted on seat belt braces,
The 9 steel O type mousing-hooks 11 together with seat belt link 16 fastener can be linked up with in falling-down prevention brake lower end.The length of strop 12 is the least
In 30 meters.
As it is shown in figure 1, the anti-fall brake of automatic contractive has high strength steel shell 2, cover top portion link 10, the center that is arranged in shell
Ratchet 4, it is arranged at the ratchet 6 bottom ratchet and pawl restoring spring 5, the inner fixing and galvanized steel wire rope 8 that coils on ratchet central shaft 3,
The outer end of galvanized steel wire rope passes bottom shell 2, is provided with galvanized steel wire rope protection ring 7 at line outlet.
As in figure 2 it is shown, described is wearable in seat belt with it, including the belt 13 of band buckle 14, be sleeved on belt two of two ends
Braces 15, two bottom bands of trouser legs 17 that two ends are sleeved on belt, it is equipped with link 16 at the back position of braces.Multiple hanging point symmetry positions of seat belt
Before and after health, it is convenient, comfortable to dress.
Using method of the present utility model is as follows:
(1) with one section of steel wire penetrating contraction type falling-down prevention brake 1 cover top portion link 10 and hang at tower crane operating board on crosspiece, with many
In 3 wire clips, steel wire rope two ends are blocked, it is ensured that contraction type falling-down prevention brake is secured firmly on tower crane operating board crosspiece；
(2) being fixed on one end of strop 12 on contraction type falling-down prevention brake 1 lower end hook 9, the other end of strop hangs downwards.Tower
Hang operator when needing up to climb, only need the remarkable passage that uniform speed slow pulls strop that hook 9 just can move to ground or centre is set up to put down
At platform；
(3) tower crane operator has dressed seat belt, carries on the arm piggyback by two braces 15, and hook 9 fasteners, through the bottom bands of trouser legs 17, are being pacified by two thighs
On link 16 on full band, or with steel O type mousing-hook 11 general's hook 9 together with link 16 fastener, take off strop and be positioned over tower crane
The position of passage is set up in bottom or centre, checks that hook is connected with link and intact can climb afterwards, the galvanized steel of falling-down prevention brake during climbing
Cord is shunk automatically with the climbing of personnel；
(4) when tower crane operator needs lower tower crane, being to have dressed seat belt equally, carry on the arm piggyback by two braces, two thighs pass the bottom bands of trouser legs,
To link up with on 9 fasteners link 16 on seat belt, or with steel O type mousing-hook general's hook 9 together with link 16 fastener, the most down
Return at ground or the central passage set up, then strop 12 one end is connected firmly with falling-down prevention brake lower end hook, then untie safety
Band and the connection of falling-down prevention brake, both hands are held strop, are slowly played back falling-down prevention brake galvanized steel wire rope, until whole galvanized steel wire ropes return
Contract complete.
When tower crane operator is at upper and lower tower crane, during if there is upper and lower excessive velocities, the back-moving spring 5 in falling-down prevention brake will be triggered,
Controlling ratchet 6 and block ratchet 4, galvanized steel wire rope will be blocked by moment, it is to avoid causes personnel's fall injury.
The novel falling-down prevention brake of this utility model can directly purchase prior art products.
