Abstract

The utility model discloses a portal device for a caterpillar crane. The portal device comprises masts and pulley blocks, wherein the masts are in box type double-limb structures, the upper parts of the two parallel masts are fixedly connected together through a connecting rod, the lower parts of the masts are mounted on a main platform through a pin shaft, support plates are mounted at the middles of the masts, a support rod is arranged between the support plates, the pulley blocks are mounted on the main platform and the masts, and a winch, the pulley blocks and the masts form a mast crane. The portal device is simple to manufacture and is good in stability.

Description

A kind of mast apparatus for crawler crane
Technical field
The utility model belongs to lifting technique field, especially relates to a kind of mast apparatus for crawler crane, is applicable to the realization of crawler crane hoist mechanism.
Background technology
What the crawler crane door frame below domestic production 250t adopted mostly at present is A type rack and panel construction, particularity due to hoisting crane work character, and user's active demand guarantees that hoisting crane hangs stability and the self-loading and self-unloading functions of loading capability, A type frame has been not suitable with current social current.
Summary of the invention
The purpose of this utility model is: a kind of mast apparatus for crawler crane simple, good stability of making is provided.
The technical solution of the utility model is: a kind of mast apparatus for crawler crane, comprise mast, assembly pulley, mast is the two limb structures of box, the top of two parallel masts is fixed together by pipe link, mast bottom is arranged on main platform by bearing pin, fagging is equipped with at mast middle part, strut is housed between fagging, between two masts of mast top, A assembly pulley is housed, winch and B assembly pulley are arranged on main platform, and winch, A assembly pulley, B assembly pulley, mast form mast and hang.
The beneficial effects of the utility model are: because mast structure is the two limb structures of box, indivedual positions adopt fagging to reinforce, and have promoted the hoisting capacity of hoisting crane.By winch, assembly pulley, mast, form mast and hang, realized the self-loading and self-unloading functions of main frame self.The utlity model has the advantages such as making is simple, low cost of manufacture, long service life, good stability, easy installation.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is birds-eye view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further, from the birds-eye view of front view of the present utility model, Fig. 2 shown in Fig. 1, can find out, the utility model mainly contains mast 1, assembly pulley and associated mechanisms and forms, the top of two parallel masts 1 is fixed together by pipe link 7, mast 1 bottom is arranged on main platform 3 by bearing pin 6, fagging 8 is equipped with at mast 1 middle part, between fagging 8 on two masts, strut 9 is housed, make overall stability good, partial portion adopts high tensile steel plate welding, has greatly increased service life.Assembly pulley is arranged on main platform 3 and above mast 1, between mast 1 top two masts, A assembly pulley 2 is housed, winch 5 and B assembly pulley 4 are arranged on main platform 3, winch 5, A assembly pulley 2, B assembly pulley 4, mast 1 form mast and hang, realize the self-loading and self-unloading functions of host part, effectively solve hoisting crane and hung the stability of carrying, and promoted to a certain extent the hoisting capacity of hoisting crane.
