Abstract
The utility model discloses an anti-climbing structure of a tower crane. The anti-climbing structure can prevent irrelevant personnel from climbing the tower crane. The anti-climbing structure of the tower crane comprises a tower crane bracket in a framework structure, wherein the tower crane bracket is internally provided with a climbing ladder along the height direction of the tower crane bracket; an anti-climbing steel plate covers the outer side of the bottom of the tower crane bracket; the height from the anti-climbing steel plate to the ground is more than 3m; the anti-climbing steel plate is provided with a climbing door for entering the inner part of the tower crane bracket after being opened; the climbing door is opened and closed by a door lock.
Description
Technical field
The utility model relates to security device field, building site, is specifically related to the security structure design of tower crane.
Background technology
Tower crane is called for short tower machine, is commonly called as tower crane.Start to manufacture in batches and application in the thirties in 20th century.The tower machine industry of China is started in the 1950's, and current domestic Ta Ji manufacturer has family more than 400.The sales volume of 2010 is 40000, and tower machine recoverable amount has reached 200,000, can be rated as No.1 Ta Ji big country of the world.But safety problem becomes the sharp sword being suspended on tower machine industry head already, seriously restricts the development of tower machine industry, and people's lives and properties are worked the mischief.The national security production supervision security expert of Public Roads Administration, the committee member expert Li Shoulin of the Zhu Jianbu building safety Committee of Experts point out, in recent years, the use amount of tower crane, elevator is on the increase, grave accident occurs again and again, bring heavy losses to people's lives and properties, caused serious social harmful effect.According to statistics, China's tower crane accidents rate was ascendant trend year by year in recent years, within 2006, was 7.20 ‰, within 2007, was 7.90 ‰, within 2008, was 8.15 ‰, within 2009, was 11.2 ‰.
Tower crane accident rate is for years high, has caused the concern of government.Within 2008, country has promulgated GB/T5031-2008 " tower crane " new standard, is that the management of China crane safety is stepped into the international rank of advanced units and laid a good foundation from technical regulation aspect.
There is a kind of phenomenon of danger in existing tower crane: some unrelated persons are climbed privately to tower crane top, and the dangerous and harm of this behavior is very large, and the management in building site has been brought to difficulty.
Utility model content
The deficiency that the utility model exists for above-mentioned prior art, provides a kind of tower crane anti-climbing structure, and it can prevent unrelated person climbing tower crane.
The utility model solves the technical scheme that its technical matters adopts: the anti-climbing structure of tower crane, and the tower crane support that comprises framed structure, described tower crane internal stent arranges ladder stand along tower crane support height direction; Described tower crane frame bottom outside is enclosed with anti-creep steel plate, and this anti-creep steel plate is greater than three meters apart from the height on ground;
On above-mentioned anti-creep steel plate, offer the climbing door that enters into tower crane internal stent after unlatching; Climbing door opens and closes by door lock.
Further: above-mentioned tower crane support bottom is fixed on base.
Further: above-mentioned ladder stand both sides are connected on tower crane support by steelframe.
The beneficial effects of the utility model are:
The anti-climbing structure of the utility model tower crane, realizes and only enters tower crane internal stent and could climb by ladder stand being arranged on to tower crane internal stent; Meanwhile, the anti-creep steel plate that is highly greater than 3 meters has been wrapped up in tower crane frame bottom outside, and owing to there is no the auxiliary of steelframe, tower crane support outside cannot be climbed, and only has just can enter tower crane internal stent by the climbing door on anti-creep steel plate and climb.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Description of reference numerals:
1-base, 2-anti-creep steel plate, 3-tower crane support, 4-ladder stand, 5-climbs door, 6-door lock.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model specific embodiment is described:
Fig. 1 shows the specific embodiment of the present utility model, as shown in the figure, the anti-climbing structure of the utility model tower crane, the tower crane support 3 that comprises framed structure, described tower crane support 3 inside arrange ladder stand 4 along tower crane support height direction; Described tower crane support 3 bottom outside are enclosed with anti-creep steel plate 2, and this anti-creep steel plate 2 is greater than three meters apart from the height on ground;
On above-mentioned anti-creep steel plate 2, offer the climbing door 5 that enters into tower crane support 3 inside after unlatching; Climbing door 5 opens and closes by door lock 6.
Preferably, above-mentioned tower crane support 3 bottoms are fixed on base 1.
Preferably, above-mentioned ladder stand 4 both sides are connected on tower crane support 3 by steelframe.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above; but the utility model is not limited to above-mentioned embodiment, all improvement in the ken that those of ordinary skills were possessed of carrying out for basis with thought of the present utility model all drop in protection domain of the present utility model.Do not depart from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
