Abstract
The utility model relates to a hand-pulling bridge crane which comprises a transverse rod of an A-shaped frame. A support is mounted on the transverse rod of the A-shaped frame, a guide rail is mounted at the bottom of the support via bolts and is an H-shaped steel rail, a manual chain-driven carrier is mounted on the guide rail, a chain block is mounted on the lower portion of the manual chain-driven carrier, a hook on the upper portion of the chain block is hooked on the manual chain-driven carrier, and a lifting hook is arranged on the lower portion of the chain block. The hand-pulling bridge crane has the advantages that the hand-pulling bridge crane is reasonable in structure and convenient to mount, and the problem that electric and hydraulic components and the like below an existing A-shaped frame of a trussed offshore platform crane cannot be hoisted and lifted under structural and special constraints of a certain region when maintained and replaced can be effectively solved; electric and hydraulic components and the like can be maintained and replaced when maintained without the aid of external hoisting equipment, and the hand-pulling bridge crane is novel in appearance, compact in structure and high in practicality.
Description
Technical field
The utility model relates to weight-lifting equipment technical field, and especially one pulls bridge crane.
Background technology
Deck crane, is the large deck machinery of one on ship, and it is a kind of equipment of ship loading and unloading goods.
Truss-like ocean platform crane, the parts such as its major part is electric, hydraulic pressure are mounted on cylindrical shell, on the turn table under A shape frame, due to the restriction of structure space, in maintenance, while changing the parts such as electric, hydraulic pressure below A shape frame, its troublesome poeration, and in this region, self there is no load-carrying ability, must be by outside weight-lifting equipment, outside weight-lifting equipment, when work, also, likely because the structure space in this region limits, need to be pulled down A shape frame; Its troublesome poeration, takes time and effort, and often removing and installing of A shape frame also can affect its setting accuracy and service life.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides one to pull bridge crane, thus make its without can complete maintenance by outside weight-lifting equipment, change the parts such as electric, hydraulic pressure, flexible and convenient to use, reliable operation, work efficiency is high.
The technical scheme that the utility model adopts is as follows:
One pulls bridge crane, comprise A shape frame cross bar, on described A shape frame cross bar, bearing is installed, the bottom of described bearing is provided with guide rail by bolt, described guide rail is bull headction, on described guide rail, manual chain-driven carrier is installed, and chain block is installed in the bottom of described manual chain-driven carrier, chain block top is hung on manual chain-driven carrier, and chain block bottom is suspension hook.
Its further technical scheme is:
Described bearing becomes bending structure;
The two ends of described guide rail are welded with mechanical position limitation mechanism.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, easy for installation, can effectively solve the parts such as electric, hydraulic pressure under truss-like ocean platform crane A shape frame in maintenance, while changing, be subject in this region self cannot hoisting and hanging problem; During maintenance, need to can not overhaul by outside weight-lifting equipment, change the parts such as electric, hydraulic pressure, it has profile novelty, compact conformation, practical.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the left view of Fig. 1.
Wherein: 1, A shape frame cross bar; 2, bearing; 3, bolt; 4, guide rail; 5, manual chain-driven carrier; 6, chain block; 7, suspension hook.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As depicted in figs. 1 and 2, the present embodiment pull bridge crane, comprise A shape frame cross bar 1, on A shape frame cross bar 1, bearing 2 is installed, the bottom of bearing 2 is provided with guide rail 4 by bolt 3, and guide rail 4 is bull headction, manual chain-driven carrier 5 is installed on guide rail 4, chain block 6 is installed in the bottom of manual chain-driven carrier 5, and chain block 6 tops are hung on manual chain-driven carrier 5, and chain block 6 bottoms are suspension hook 7.
2 one-tenth bending structures of bearing.
The two ends of guide rail 4 are welded with mechanical position limitation mechanism.Stop gear adopts shrouding, the setting of shrouding, the shift position of control manual chain-driven carrier 5.
Manual chain-driven carrier described in the utility model 5 is for by walking guide rail wheel, and gear pair pulls the traveling gear that pulls of the compositions such as chain, frame.
In actual use procedure, by suspension hook 7, wherein need electric, the hydraulic unit of maintenance under A shape frame, easy to use.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
