Background technology
In engineering, some long-armed device need be around a center rotating, the working platform of long-armed device load is rotated in carrying can only arrange a side, because the armed lever of the long-armed device of rotation is long, load is large, need primary structure member be set in the rostral-caudal of rotating long-armed device and carry the load that rotates long-armed device, and be equipped with corresponding member power is transmitted to working platform, so can improve the stress condition that rotates long-armed device.
When work, working platform is relatively-stationary, and is rotated long-armed device and conduct vertical force and the horizontal force of coming, and rotates long-armed device and need to rotate as required.If as rotating the member of realizing with stressed function, structural element design will be very complicated with processing and fabricating with radial antifriction bearing, thrust bearing.
Some engineer equipment system, rotate long-armed device rotary speed slower, but the long load of armed lever is large, and upper and lower two working platformes is set.Revolution support tool for revolute function, bear level and vertical load ability.Support with two revolutions that are contained in respectively on upper and lower working platform, as rotating the final stress point of long-armed device, can realize rotating function, and bear larger load, improvement will be rotated long-armed device stress condition.
Utility model content
The oblique pull that the utility model provides a kind of double back to turn support is rotated long-armed apparatus system, solve the problem of rotating long-armed device load carrying, need be contained on different platforms for slew gear, and it is low to rotate long-armed device velocity of rotation, the feature that load is large, utilize the function of revolution support rotating and can bear large level and vertical load performance characteristics, described system dispoal choice is upper, two revolutions of concentric of lower working platform are supported, realize wraparound and turn centre of support axle rotor---rotate the rotating function of long-armed device, simplify the structure of rotating long-armed apparatus system rotating part, optimize and rotate long-armed device force-bearing situation, reduce and rotate long-armed apparatus structure stress, improve and rotate long-armed device ability to bear, its technical scheme is as described below:
A kind of double back turns the oblique pull of support and rotates long-armed apparatus system, comprise rotate long-armed and two arrange up and down and the relative static working platform of when work maintenance, be divided into working platform and lower working platform, described upper working platform is provided with upper rotary and supports, described upper rotary supports and is installed with the upper flange plate that possesses pin joint, described lower working platform is provided with lower revolution and supports, described upper rotary supports and lower revolution is supported with identical rotary middle spindle, described lower revolution is supported and is installed with lower flange, the tail end of the long-armed device of described rotation is firmly connected with lower flange, front end is provided with pin joint, diagonal member is hinged with the pin joint of upper flange plate and the long-armed device of rotation respectively.
Described upper rotary supports the upper plane that is arranged on working platform, described upper flange plate be arranged on that upper rotary supports above.
The lower plane that is arranged on lower working platform is supported in described lower revolution, and described lower flange is arranged on below lower revolution support.
Described upper rotary supports and lower revolution support is arranged in respectively on the same angle of corresponding working platform.
The long-armed device of rotation that the utility model is lower for velocity of rotation, armed lever is long, before and after 2 supports can improve that it is stressed, ensure its safety, support the parts of realizing as revolute function with revolution, simplify slew gear, select suitable revolution to support simultaneously and can carry the large load that rotates long-armed device, turn round support by reasonable selection, can be used for bearing large load and need wraparound to turn the engineer equipment field of center rotating armed lever device.
Brief description of the drawings
Be described further below in conjunction with accompanying drawing and example,
Fig. 1 is that the oblique pull that a kind of double back that the utility model provides turns support is rotated long-armed apparatus system schematic diagram;
In figure: 1-working platform (on), 2-revolution support (on), 3-rotates long-armed device, 4-flange (on), 5-working platform (under), 6-revolution support (under), 7.-flange (under), 8-diagonal member, 9-pin joint; 10-pin joint.
Detailed description of the invention
Described double back turns the oblique pull of support and rotates long-armed apparatus system as shown in Figure 1, be provided with the essentially identical working platform 1 of upper and lower two structures and working platform 5, and structure is basic identical, rotates long-armed device 3 two working platform transfixions in the time of rotation work.
On upper working platform 1, the end of plane fixedly mounts a set of revolution and supports 2, revolution is supported 2 and is rotated long-armed device 3 tops in need revolution, revolution is supported 2 tops and is fixedly mounted the flange 4 that possesses pin joint 9, flange arranges pin joint on 4 limits, flange plate structure with revolution support 2 mate and pin joint at avris.Fixedly mount a set of revolution in the end of the lower plane of lower working platform 5 and support 6,6 bottom fixed installation flange dishes 7 are supported in revolution.
Revolution is supported 2 and is arranged in upper plane one side of working platform 1, and is firmly connected with it.Revolution is supported 6 and is arranged in lower plane one side of working platform 5, and is firmly connected with it.Same rotary middle spindle is supported in revolution up and down, and is arranged in separately one jiao of working platform.
Rotate long-armed device 3 tail ends and flange 7 bottoms fixed, rotate long-armed device 3 front ends and establish pin joint 10, diagonal member 8 is connected with the pin joint 9 of flange 4 and the pin joint 10 of the long-armed device 3 of rotation respectively.
While rotating long-armed device 3 rotation work, on it, some equipment can be installed as required, when it rotates, these equipment also rotate.Rotate long-armed device 3 working loads and pass to corresponding primary structure member by the fixed place of tail end and the pin joint 10 of front end, finally pass on working platform.
Like this, rotate long-armed device 3 and possess two load bearing points, rotate the load of long-armed device 3 tail ends and pass to lower working platform 5 by flange 7, the load that rotates long-armed device 7 front ends supports 2 by hinged diagonal member 8, flange 4, revolution and passes to upper working platform 1, and the double back that so formation can be born larger load and be possessed revolute function turns the oblique pull of support and rotates long-armed apparatus system.
The oblique pull that turns support by above-mentioned double back is rotated long-armed apparatus system, rotate long-armed device and realize rotating function, and its stress improves, and rotating mechanism is simplified more, and processing and fabricating is easy, can bear larger working load.
