Abstract
The invention relates to a rotary arm for a hoisting crane. The rotary arm comprises a body, a fixed seat which is fixedly installed on one side of the body, a fixed shaft which is arranged on the outer side of the fixed seat, a bearing which is sleeved on the fixed shaft, a thrusting bearing which is sleeved on the bottom of the fixed shaft, a steel pipe which is tightly sleeved on the periphery of the bearing and a connecting piece which is fixedly welded to the steel pipe, wherein the rotary arm is fixedly connected with a steel pipe provided with a connecting piece by the steel plate fixedly provided with a connecting piece, and the rotary arm also comprises an adjusting arm, the adjusting arm and the rotary arm are connected to one side of the body through a same connecting structure, and the adjusting arm stays on the same vertical line with the connecting structure of the rotary arm, and a rotary end of the adjusting arm is connected to the rotary end of the rotary arm. The rotary arm is simple in structure and convenient to use, and the application range of the rotary mechanical device and particularly the crane device can be greatly enlarged.
Description
Technical field
the present invention relates to mechanical equipment field, particularly relate 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 invention 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 preferred embodiment of the present invention, the structure that described regulating arm is adjustable in length.
as another kind of preferred version of the present invention, plural described bearing is installed on described anchor shaft.
as another preferred version of the present invention, described attaching parts is the arcuate structure that is provided with connecting bore.
as another preferred version of the present invention, between described two or more attaching parts, by bolt, connect.
as another preferred version of the present invention, 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 present invention has the following advantages: the present invention 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.
Accompanying drawing explanation
fig. 1 structural representation of the present invention.
number in the figure is:
1-body, 2-permanent seat, 21-anchor shaft
22-bearing, 23-thrust baring, 3-steel pipe
4-attaching parts, 5-steel plate, 6-pivot arm
7-regulating arm.
The specific embodiment
below this process example is elaborated, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
as shown in structural representation as of the present invention in Fig. 1, 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 two or more 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 the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
