Description
Technical field
The present invention relates to one kind climbing safety device, and in particular to a kind of straight trip fall arrest mechanical device on tower crane.
Background technology
Tower crane is a kind of crane gear also known as derrick crane the most frequently used on construction site, with a section spreading,
For hanging the raw material of the constructions such as working reinforcing bar, wood stupefied, concrete, steel pipe.Tower crane is a kind of essential on building site
Equipment.The function of tower crane point is subject to the upper load that arm support drawstring and counter-jib drawstring are transmitted, and by turning round pylon, turning
The structure member formula of platform, bearing etc. directly passes to tower body structure by turntable.There is truncated cone pillar from a liter tower top, lean forward or hypsokinesis
Truncated cone pillar, herringbone posture and diagonal brace posture.Every upper rotary tower crane is both needed to set balance weight, and its function is supporting balance weight, is used
With effect aspect and hoisting moment trimming moment in opposite direction required on Construction designing.In addition to balance weight, also Chang Qi
Afterbody installs lifting mechanism.Why homostasis weight is placed in counter-jib tail end to raising together, first can play part with recast
With, second increase the distance between rope reel and pinnacle of a pagoda guide wheel, with the row of sharp steel wire rope around and avoid disorder cable phenomenon.Balance weight
Consumption and counter-jib length inversely, and balance between arm lengths and jib length and there is certain proportion and close
System.Counterpoise is considerable, and light-duty tower crane typically at least wants 3 ~ 4t, and heavy wants nearly 30t.
Tower crane is the main heavy construction machinery of construction site, because its lifting altitude is high, broad covered area, efficiency it is high etc.
Feature and be widely used, especially in high-building construction, tower crane is raised with its superior lifting transport performance, good rising
Degree and work range, as one of transporting equipment main in project construction, are responsible for main vertical transport task.It is existing to build
Derrick crane cat ladder that job site uses is built without guard ring, when derrick crane peace tears upper and lower with the driver vertical ladder of personnel open, note
When meaning power is not concentrated or ladder humidity is skidded, easily step on sky and fall, cause pendant casualty accident high to occur, there is potential safety hazard.
The content of the invention
The technical problems to be solved by the invention are absent minded or during the moist skidding of ladder, easily step on empty pendant
Fall, it is therefore intended that a kind of straight trip fall arrest mechanical device on tower crane is provided, solve absent minded or ladder moist
During skidding, the empty problem fallen easily is stepped on.
The present invention is achieved through the following technical solutions：
A kind of straight trip fall arrest mechanical device on tower crane, including several tower crane columns and tower crane cross bar, the tower crane stand
Post and tower crane cross bar constitute rectangular frame, also including the anti-drop net with crotch, the mesh of the anti-drop net a diameter of 300 ~
400mm, the anti-drop net is fixed by the buckle at 4 angles of crotch and rectangular frame bottom surface, the one of side of rectangular frame
Face is provided with tower crane cat ladder.Tower crane is the main heavy construction machinery of construction site, because its lifting altitude is high, coverage rate
Extensively, be widely used the features such as efficiency high, especially in high-building construction, tower crane with its superior lifting transport performance,
Good lifting altitude and work range, as one of transporting equipment main in project construction, are responsible for main vertical fortune
Defeated task.The derrick crane cat ladder that existing building job site uses is torn open on personnel and driver without guard ring, derrick crane peace
During lower vertical ladder, during the moist skidding of absent minded or ladder, easily step on sky and fall, cause pendant casualty accident high to occur,
There is potential safety hazard, the present invention employs increase anti-drop net to solve this problem, can according to the actual requirements determine how many sections
Highly increase anti-drop net, anti-drop net protects derrick crane to pacify when tearing the upper and lower vertical ladder of personnel and driver open, absent minded
Or during ladder humidity skidding, easily step on sky and fall, cause pendant casualty accident high to occur, solve the potential safety hazard of presence.It is anti-
A diameter of 300 ~ the 400mm for falling the mesh of net is the result for going out according to newest material analysis, the carrying effect in the range of this
Fruit is most reasonable.
It is described to snap connection between tower crane column and tower crane cross bar.Buckle is arranged on the company of tower crane column and tower crane cross bar
Place is met, is to enhance steadiness, more can ensure that and connected with anti-drop net.
The anti-drop net sets passway, and anti-drop net is made up of nylon rope, with elasticity.Someone is may insure with elasticity
Imprudence plays a part of one and unloads power when dropping.The passway of setting is in order that operating personnel pass through.
The tower crane cat ladder, is bolted on tower crane cross bar, connects logical between the tower crane cross bar and passway
Road valve.The setting of this channel valve has two layers of meaning, and ground floor is in order to avoid being fallen from passway when imprudence drops
Fall, the second layer is in order to avoid many workmans for making trouble of these collection often can be enterprising by tower top on climbing tower crane or other skyscrapers
Row is made trouble, and so just brings very big potential safety hazard to construction, also has a strong impact on other people personal safety, and this channel valve can
In lowermost 2 layers of setting lockset.
The channel valve is connected with tower crane cross bar axle.Channel valve is active link, can prolong tower crane cross bar or so
Rotation, the field angle of this rotation can be adjusted.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of straight trip fall arrest mechanical device on tower crane of the present invention, anti-drop net protect derrick crane pacify the personnel that tear open with
During the upper and lower vertical ladder of driver, during the moist skidding of absent minded or ladder, easily step on sky and fall, cause pendant casualty accident high
Occur, solve the potential safety hazard of presence.A diameter of 300 ~ 400mm of the mesh of anti-drop net is according to newest material analysis
The result for going out, the supporting effect in the range of this is most reasonable；
2nd, a kind of straight trip fall arrest mechanical device on tower crane of the present invention, the setting of channel valve has two layers of meaning, first
Layer is that, in order to avoid being fallen from passway when imprudence drops, the second layer is in order to avoid many workmans for making trouble of these collection often can
By being made trouble on tower top on climbing tower crane or other skyscrapers, very big potential safety hazard just so is brought to construction, also sternly
Ghost image rings other people personal safety, and this channel valve can be in lowermost 2 layers of setting lockset；
3rd, a kind of straight trip fall arrest mechanical device on tower crane of the present invention, buckle is arranged on the company of tower crane column and tower crane cross bar
Place is met, is to enhance steadiness, more can ensure that and connected with anti-drop net.
