Abstract
The invention discloses a novel tower crane anti-climbing structure, which can prevent irrelevant people from climbing a tower crane. The novel tower crane anti-climbing structure comprises a tower crane support of a framework structure, wherein the tower crane support is internally provided with a climbing ladder along the height direction of the tower crane support; the outer side of the bottom of the tower crane is wrapped with an anti-climbing steel plate; the height from the anti-climbing steel plate to the ground is greater than 3 meters; the anti-climbing steel plate is provided with a climbing door which enters the interior of the tower crane support after being started, and is opened and closed via a door lock.
Description
Technical field
The present invention relates to security device field, building site, be 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.Batch micro operations and application has been started 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 be suspended on tower machine industry head already, the development of serious restriction tower machine industry, works the mischief to people's lives and properties.National security production supervision Public Roads Administration security expert, Zhu Jianbu building safety Committee of Experts committee member expert Li Shoulin 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, cause serious social harmful effect.According to statistics, China's tower crane accidents rate was in ascendant trend year by year in recent years, and within 2006, being 7.20 ‰, 2007 is 7.90 ‰, within 2008, is 8.15 ‰, within 2009, is 11.2 ‰.
Tower crane accident rate remains high for years, causes 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 to tower crane top privately, and the danger of this behavior and harm are very large, bring difficulty to the management in building site.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, provide a kind of novel tower crane anti-climbing structure, it can prevent unrelated person from climbing tower crane.
The technical solution adopted for the present invention to solve the technical problems is: the anti-climbing structure of novel tower crane, comprises the tower crane support of framed structure, and described tower crane internal stent arranges ladder stand along tower crane support height direction; Be enclosed with anti-creep steel plate outside described tower crane frame bottom, this anti-creep steel plate is greater than three meters apart from the height on ground;
The climbing door of tower crane internal stent is entered into after unlatching offered by above-mentioned anti-creep steel plate; Climbing door is opened and closed 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 invention has the beneficial effects as follows:
The anti-climbing structure of the novel tower crane of the present invention, only enters tower crane internal stent could climb by ladder stand is arranged on tower crane internal stent to realize; Meanwhile, wrapped up the anti-creep steel plate being highly greater than 3 meters outside tower crane frame bottom, auxiliary due to without steelframe, tower crane bracket outer cannot be climbed, and only has just can enter tower crane internal stent by the climbing door on anti-creep steel plate and climb.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the invention is described:
Fig. 1 shows the specific embodiment of the present invention, and as shown in the figure, the anti-climbing structure of the novel tower crane of the present invention, comprises the tower crane support 3 of framed structure, and described tower crane support 3 inside arranges ladder stand 4 along tower crane support height direction; Described tower crane support 3 bottom outside is 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;
The climbing door 5 of tower crane support 3 inside is entered into after unlatching offered by above-mentioned anti-creep steel plate 2; Climbing door 5 is opened and closed by door lock 6.
Preferably, above-mentioned tower crane support 3 bottom is 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 preferred embodiment for the present invention is explained in detail above; but the invention is not restricted to above-mentioned embodiment, all improvement in the ken that those of ordinary skill in the art possess carried out based on thought of the present invention all drop in protection scope of the present invention.
Do not depart from the spirit and scope of the present invention and can make other changes many and remodeling.Should be appreciated that and the invention is not restricted to specific embodiment, scope of the present invention is defined by the following claims.
