Abstract
The utility model relates to a sectional type crane jib. The sectional type crane jib comprises a boom root section, a boom middle section and a boom head section, wherein the boom root section and the boom middle section as well as the boom middle section and the boom head section are respectively connected with each other through a connecting device, and the connecting devices are respectively arranged at four vertex angles of a connecting end surface. The sectional type crane jib has the beneficial effects of lowering the machining difficulty and reducing the repair work for structural distortion, improving the production efficiency, further improving the product quality, and reducing the transportation cost.
Description
Technical field
This utility model relates to a kind of crane arm of hoisting crane, and particularly a kind of sectional type crane boom belongs to hoisting crane manufacturing technology field.
Background technology
Crane arm is the keystone configuration of hoisting crane, because this framing member is tube truss structure, and body junction member overlength, make troubles for transportation and on-the-spot the installation, increase transportation and cost of installation, and affect erection schedule, affect user's operating needs, also bring certain impact to enterprise.
To the problems referred to above, way commonly used is that the crane arm main chord is disconnected, and transports to the building site, be welded into one to the on-the-spot crane of renting, and weld seam needs flaw detection.Thereby produced unnecessary various expenses, increased enterprise cost, erection work has been brought certain impact.
Summary of the invention
Goal of the invention: the purpose of this utility model provides and a kind ofly crane boom can be split into several sections sectional type crane booms of assembling again when transporting to the erecting stage.
Technical scheme: a kind of sectional type crane boom, comprise jib root segment, jib stage casing and jib head section, be connected by connecting device respectively between between described jib root segment and the jib stage casing and jib stage casing and the jib head section, described connecting device is separately positioned on four drift angles of connecting end surface.For the ease of transportation crane arm is divided into some sections, connect by detachable connecting device between each section, respectively each section is welded into independent integral body in order to improve connection reliability, connecting end surface is identical to be square, and connecting device is separately positioned on four drift angles of connecting end surface.The length of each section is as the criterion to be fit to transportation.
In order further to shorten the length of crane arm, described jib stage casing comprises at least two sections truss structures, and the connection between the truss structure connects by connecting device.
Connect for convenient, described connecting device comprises that public connector, female connector and connection bearing pin be connected described public connector and be connected the crane arm section welding that is connected with needs with female connector, and public connector inserts in the female connector to be decided by the connecting pin shaft lock.
Beneficial effect: the utility model has reduced mechanical processing difficulty, has reduced the repair of structural distortion, has improved production efficiency, and product design also further improves, and has reduced traffic cost.
Description of drawings
Fig. 1 is crane arm integral structure scheme drawing of the present utility model;
Fig. 2 is the structural representation of the utility model connecting device.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of sectional type crane boom, comprise jib root segment 1, jib stage casing 2 and jib head section 3, be connected by connecting device 4 respectively between between described jib root segment 1 and the jib stage casing 2 and jib stage casing 2 and the jib head section 3, described connecting device 4 is separately positioned on four drift angles of connecting end surface.Described jib stage casing 2 comprises three sections truss structures, and the connection between the truss structure connects by connecting device 4.For the ease of transportation crane arm is divided into some sections, connect by detachable connecting device 4 between each section, respectively each section is welded into independent integral body in order to improve connection reliability, connecting end surface is identical to be square, and connecting device 4 is separately positioned on four drift angles of connecting end surface.The length of each section is as the criterion to be fit to transportation.
As shown in Figure 2, described connecting device 4 comprises public connector 5, female connector 6 and is connected bearing pin 7, and described public connector 5 is connected the crane arm section welding that is connected with needs respectively with female connector, and public connector 5 inserts in the female connectors 6 by connecting bearing pin 7 lockings.
