Description
Technical field
The utility model relates to construction safety guard technology field, particularly a kind of tower crane anti-creep device.
Background technology
Tower crane, has another name called tower crane, is one of construction machinery and equipment be most widely used in the realm of building construction.Along with the widespread use of tower crane, safety problem has also become the cardinal task of pendulum in face of unit in charge of construction.The potential safety hazard existed in current tower crane construction is: usually have some personnel irrelevant with construction, and due to reasons such as curiosities, climbing is to tower crane top privately.This behavior disguise is very strong, but harm is but very large, is easy to cause unnecessary personnel's injury, also brings difficulty to site construction management simultaneously.
In order to avoid unrelated person climbs tower crane top without authorization, at present, the common way of construction enterprises is on tower crane, arrange anti-creep net, anti-creep net is divided into three web plates: two blocks of side web plates and one block of center web plate, the corner of anti-creep net arranges four rectangular through holes, and four pillars of tower crane are just through this through hole.The shortcoming of this structure is that comformability is too poor, if having cat ladder in the middle of tower crane, center web plate just cannot directly be installed, cat ladder of must first dismantling; If tower crane pillar is provided with reinforcement gusset, the online rectangular through holes of anti-creep will be passed through; Therefore, a kind of novel, that comformability is stronger tower crane anti-creep device is needed.
Utility model content
The utility model proposes a kind of tower crane anti-creep device, solve the problem of tower crane anti-creep device bad adaptability in prior art.
The technical solution of the utility model is achieved in that a kind of tower crane anti-creep device, comprise the anti-creep net be horizontally set on tower crane and the anti-creep door being arranged on cat ladder position, described anti-creep net comprises two pieces and is bolted and is with side jaggy web plate, and two blocks of middle web plates being positioned at described breach, formed between described side web plate and described middle web plate and for tower crane pillar and the through hole that gusset pass through can be strengthened.Middle web plate is designed to two pieces, when being provided with cat ladder like this in the middle of tower crane, cat ladder can being removed and just anti-creep net can be installed, improve the comformability of this anti-creep device.
In the middle of described two pieces, web plate opposite side is respectively equipped with crossbeam, and described middle web plate is connected with described side web plate by the bolt be arranged on described crossbeam, and described crossbeam two ends lower surface is provided with anti-fall plate, and by this anti-fall board on tower crane frame.During installation, first anti-fall angle steel is stuck on tower crane frame, prevents middle web plate from falling, not only convenient installation, and improve safety.
The side of described anti-creep door is connected with the first middle web plate by hinge, and another opposite side is provided with bidirectional gate nose, and the second middle web plate is provided with the fixed gate nose coordinated with described bidirectional gate nose, and described bidirectional gate nose is connected by tapered end with described fixed gate nose.By arranging bidirectional gate nose, anti-creep door lock all can be lived when upper and lower tower crane by staff, more effectively prevents other unrelated persons from entering tower crane.
The contact bar supporting described anti-creep door is provided with between the below of described anti-creep door, described middle web plate.During the upper tower crane of staff, need to step down on anti-creep door, contact bar is arranged on the below of anti-creep door, increases the load-carrying capacity of anti-creep door, safer.
Described middle web plate is provided with stiffener.During the upper tower crane of staff, also need to step down on the middle web plate on anti-creep door side, middle web plate arranges stiffener, increases the load-carrying capacity of middle web plate, add safety.
Middle web plate is designed to two pieces by the anti-creep net of a kind of tower crane of the utility model anti-creep device, can be suitable for the tower crane that there is cat ladder centre, not only easy for installation, also substantially increases the Applicable scope of anti-creep device; Be provided with anti-fall angle steel at the two ends of mid-level net, further increase safety, there is substantial feature and progress.
