Description

A kind of construction safety type tower crane

Technical field

Architectural Equipment technical field is the utility model is related to, is specially a kind of construction safety type tower crane.

Background technology

Tower crane is a kind of common lifting equipment in construction site, also known as derrick crane, for slinging reinforcing bar, wood stupefied and steel The construction material such as pipe.Tower crane driver needs climbing to the tower crane driver's cabin out of tower crane standard knot to carry out driving for tower crane daily Sail, in order to avoid the personnel beyond driver climb from tower crane bottom and cause security risk, construction site is often required to set up one kind Easy anti-climbing scaffold.This anti-climbing scaffold should have the function of preventing that non-working person from climbing, and meet other again Requirement in terms of safety standard, but although the general scaffold simply set up possesses anti-climbing function, but its framework is excessively simple It is single, only possess symbolistic meaning, actual anti-climbing effect is little, and the utility model provides a kind of construction safety for this Type tower crane is used to solve the above problems.

Utility model content

The purpose of this utility model is to provide a kind of construction safety type tower crane, to solve to carry in above-mentioned background technology The problem of going out.

To achieve the above object, the utility model provides following technical solution：A kind of construction safety type tower crane, including Tower crane body and fixed link, the tower crane body and fixed link periphery are installed with protective shell, and protective shell is quadrangle Tubbiness, for the protective shell while being equipped with opening, opening is equipped with sliding door, and the sliding door is connected by hinge and protective shell activity Connect, the tower crane body interior is installed with cat ladder frame, and the cat ladder frame is two, and respectively right between every cat ladder frame Some supporting rods should be equipped with, one end of the every supporting rod is respectively flexibly connected by spring hinge with cat ladder frame, and separately One end is respectively equipped with some jacks, and the supporting rod is connected with connecting plate, and the connecting plate is installed with and jack The limited post of corresponding number.

Preferably, the cat ladder frame height is between two to three meters, and the supporting rod that activity is installed between every group of cat ladder frame Distance in-between is 30 centimetres, supporting rod at least seven to ten groups.

Preferably, for the supporting bar top at least provided with two jacks, every group of supporting rod is equipped with least four jacks, and inserts Hole one end is closed, and another end opening, the blind end of jack is fixed with sheet metal.

Preferably, the connecting plate is installed with upper mounted plate above limited post, and connecting plate is below limited post Bottom plate is installed with, limited post described in every group at least four, and spacing top end is respectively installed with suction iron Stone.

Preferably, the junction of the sliding door and the protective shell other end is equipped with door lock, and is installed with above door lock Handle, the protective shell surface is extremely smooth, and protective shell height is between two to three meters.

Compared with prior art, the beneficial effects of the utility model are：

1st, compared with not having anti-climb facility or simple and crude anti-climb facility in the past, tower crane body periphery is fixedly mounted Protective shell is first of anti-creep facility, and height and extremely smooth surface due to three meters of protective shell, make to want arbitrarily climbing Person is difficult to fulfil one's wish；

2nd, cat ladder frame and the support plate that can be rotated upwardly and downwardly by spring hinge, in no connecting plate and thereon spacing Column and jack are used cooperatively, and want to climb upwards along ladder stand even if violation climbing person destroys door lock, because without connecting plate Cooperation, supporting rod will be rotated down when forced downwards, will not provide the support effect that climbing person climbs upwards, from And it effectively prevent the climbing movement of violation climbing person under conditions of personal safety is not influenced；

If the 3, staff wants to climb to the work of tower crane operating room, after door lock is opened with key, then connecting rod is taken out, Making limited post, upper and lower fixing plate is respectively fixed on supporting rod according in the correspondence position insertion jack of the jack on supporting rod Upper and lower ends, just complete the fixation to supporting rod at this time, staff can smoothly get over ladder stand and reach tower crane body On the ladder itself carried so reach operating room.
