Abstract
The utility model discloses a crawling ladder installing structure of a tower-type crane. The crawling ladder installing structure of the tower-type crane comprises ladder beams of a crawling ladder and diagonal draw bars which are arranged on a standard section of the tower-type crane, hooks are arranged on the back, close to the top of the ladder beams, and through holes which are matched with the hooks are arranged on the diagonal draw bars. Connecting sleeves are arranged on the top of the ladder beams. The hook and the through holes are matched and connected, and fixed by the connecting sleeves, the crawling ladder installing structure of the tower-type crane is convenient to install, reliable to connect and low in price. Meanwhile, a detachable connecting structure is convenient for maintenance personnel to examine and repair daily and transport among different construction sites.
Description
Technical field
The utility model relates to the tower crane field, is specifically related to the cat ladder mounting structure of tower crane.
Background technology
In recent years, along with the rapid growth of China's economic construction, the capital construction scale constantly enlarges, being on the increase of high-building construction particularly, and the application of tower crane is more and more extensive.Each standard knot of tower crane is provided with cat ladder, so that up and down tower machine use of Operation and maintenance personnel.Present most of producer is welded on cat ladder on the standard knot, and also useful bolt is connected on the standard knot.The mode cost of installation of welding is higher and can not dismantle, and is not easy to maintenance and transportation.The bolt connection is loaded down with trivial details, and tower crane generally all is open work, and easy corrosion is located in bolted slit, thereby causes Joint failure that personal security is threatened.
Summary of the invention
The technical problems to be solved in the utility model provides the cat ladder mounting structure of tower crane, and is simple in structure, easy for installation, cheap, and it is high to be convenient to dismounting and safe reliability.
The utility model is achieved through the following technical solutions:
The cat ladder mounting structure of tower crane comprises the terraced beam of cat ladder and the digonal link on the crane mast section, is provided with hook near the back side of described terraced back section, and described digonal link is provided with the through hole that matches with described hook; Described terraced back section is provided with adapter sleeve.
The further improvement project of the utility model is, the neck of hook of described hook is parallel to terraced beam to be fixed, and Open Side Down for described hook.
The utility model further improvement project is, described terraced beam is angle steel, and the inside dimension of described adapter sleeve is slightly larger than the angle steel length of side.
The utility model further improvement project is, the transversal surface that is arranged at the adapter sleeve of described two terraced back sections is the shaped as frame of relative opening.
The utility model further improvement project is that described adapter sleeve is to the youthful and the elderly 90mm.
The utility model compared with prior art has the following advantages:
One, the utility model is connected by hook and through hole and adds the fixing of upper top adapter sleeve, easy for installation, connect reliable and cheap.
Two, the utility model adopts the detouchable connection structure to be convenient to maintainer's maintenance repair and the transportation of tower machine between different building sites.
