Abstract

The utility model relates to a rotating arm of a crane. The rotating arm comprises a body, a fixed seat fixedly mounted on one side of the body, a fixed shaft arranged on the outer side of the fixed seat, bearings arranged on the fixed shaft in a sleeving manner, a thrust bearing arranged at the bottom of the fixed shaft in a sleeving manner, a steel pipe tightly arranged at the peripheries of the bearings in a sleeving manner as well as connecting pieces fixedly welded to the steel pipe, wherein the rotating arm is fixedly connected with the steel pipe equipped with the connecting pieces through steel plates fixedly equipped with connecting pieces; the rotating arm further comprises an adjusting arm, the adjusting arm and the rotating arm are connected on one side of the body through identical connecting structures, the connecting structure of the adjusting arm and the connecting structure of the rotating arm are located on the same perpendicular line, and a rotating end of the adjusting arm is connected to a rotating end of the rotating arm. The rotating arm of the crane is simple in structure and convenient to use, and the application range of rotating mechanical equipment especially crane equipment is broadened greatly.

Description

Turned crane pivot arm

Technical field

the utility model relates to mechanical equipment field, particularly relates to the swing boom configuration of weight-lifting equipment.

Background technology

machinery refers to the general name of machine and mechanism.Machinery can help people to reduce work difficulty or labour-saving tool device exactly, as the article of chopsticks, broom and tweezers one class, can be called as machinery, and they are simple machines.And complicated machinery is exactly to consist of two or more simple machine.Conventionally the machinery of these more complicated is called to machine.From the viewpoint of structure and motion, mechanism and machine indistinction, be loosely referred to as machinery.A set of machinery comprises a lot of version, as track, lifting structure, travel mechanism, rotational structure, propulsion source etc.The arm of existing machinery equipment is rotatable type, but which round end mobile space is limited in scope, and Applicable scope is little.Therefore, how to improve the boom structure of mechanical equipment, improve its Applicable scope and become the problem that mechanical equipment field need to solve.

Summary of the invention

for solving the arm of mechanical equipment in prior art, rotate end moving range limited space, field of application little problem, the utility model provides following technical scheme:

a kind of turned crane pivot arm, it comprises body, be fixedly installed in the permanent seat of described body one side, be arranged at the anchor shaft in described permanent seat outside, be sheathed on the bearing of described anchor shaft, be sheathed on the thrust baring of described anchor shaft bottom, be locked on the steel pipe of described bearing periphery and the attaching parts that is fixedly welded in described steel pipe, pivot arm is fixedly connected with the steel pipe that attaching parts is installed by being installed with the steel plate of attaching parts, it also comprises regulating arm, described regulating arm and described pivot arm are connected in a side of described body by same connection structure, and be positioned on same perpendicular line with the connection structure of described pivot arm, the rotation end of described regulating arm is connected in the rotation end of described pivot arm.

as a kind of preferred version of the present utility model, the structure that described regulating arm is adjustable in length.

as another kind of preferred version of the present utility model, plural described bearing is installed on described anchor shaft.

as another preferred version of the present utility model, described attaching parts is the arcuate structure that is provided with connecting bore.

as another preferred version of the present utility model, between described plural attaching parts, by bolt, connect.

as another preferred version of the present utility model, described steel plate has two, and the attaching parts that is connected in described steel plate is fixedly clamped and is installed on the attaching parts of described steel pipe.

the utility model has the following advantages: the utility model is simple in structure, easy to use, by increasing plain bearing and thrust baring between the steel pipe in rotation mutually, realize pivot arm efficient, be arranged in horizontal plane and rotate, by regulating arm, change the height of pivot arm simultaneously, thereby change the plane that pivot arm rotates, greatly improved the particularly Applicable scope of crane facility of rotation class mechanical equipment.

the specific embodiment

below this process example is elaborated, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

as shown in Fig. 1 the utility model structural representation, a kind of turned crane pivot arm, it comprises body 1, be fixedly installed in the permanent seat 2 of described body 1 one sides, be arranged at the anchor shaft 21 in described permanent seat 2 outsides, be sheathed on the bearing 22 of described anchor shaft 21, be sheathed on the thrust baring 23 of described anchor shaft 21 bottoms, be locked on the steel pipe 3 of described bearing 22 peripheries and the attaching parts 4 that is fixedly welded in described steel pipe 3, pivot arm 6 is fixedly connected with the steel pipe 3 that attaching parts 4 is installed by being installed with the steel plate 5 of attaching parts 4, it also comprises regulating arm 7, described regulating arm 7 is connected in a side of described body 1 with described pivot arm 6 by same connection structure, and be positioned on same perpendicular line with the connection structure of described pivot arm 6, the rotation end of described regulating arm 7 is connected in the rotation end of described pivot arm 6.

the structure that described regulating arm 7 is adjustable in length.Plural described bearing 22 is installed on described anchor shaft 21.Described attaching parts 4 is for being provided with the arcuate structure of connecting bore.Between described plural attaching parts 4, by bolt, connect.

described steel plate 5 has two, and the attaching parts 4 that is connected in described steel plate 5 is fixedly clamped and is installed on the attaching parts 4 of described steel pipe 3.

the above; it is only one of specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
