Abstract
The utility model is portal frame elevating translational mechanism, including portal frame, the synchronization lifting component that is set at the top of the portal frame and the operation wheel for being set to the portal frame bottom；The synchronization lifting component includes several screw lifts that uniform arrangement is set at the top of the portal frame, the fixed block for joint test case being set on the lead screw of the screw lift.The utility model realizes the lifting of chamber by several screw lifts of synchronization lifting, ensures the stationarity of chamber in lifting process, guarantee test efficiency and experiment accuracy rate.
Description
Technical field
The utility model is related to technical field of test equipment, specifically, its displaying is integrated for temperature-humidity-vibration three
A kind of portal frame elevating translational mechanism that chamber is used when carrying out height and horizontal position changes.
Background technology
Three combined test chamber of temperature-humidity-vibration in environmental test equipment need to be done with shake table vertical vibration and
Horizontal vibration is tested, and usual vertical vibration and horizontal vibration use different shake tables.
Vertical vibration table is different from horizontal vibration platform height, when chamber needs to convert between, needs to try
Platform is tested to be promoted or be reduced to corresponding height, then mobile its installation position of realization by chamber horizontal direction migration.
The needs of height change when realizing this chamber migration by hydraulic lift at this stage, however this liter
It is expensive to drop platform, and limited load bearing capacities, cooperation difficulty height is assembled with chamber, simultaneously as existing hydraulic elevator platform
The phenomenon that there is also double swerves in lifting process, there are security risks.
Therefore, it is necessary to provide a kind of portal frame elevating translational mechanism to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of portal frame elevating translational mechanism.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of portal frame elevating translational mechanism, including portal frame, be set at the top of the portal frame synchronization lifting component,
And it is set to the operation wheel of the portal frame bottom；
The synchronization lifting component includes several screw lifts, the setting that uniform arrangement is set at the top of the portal frame
In the fixed block for joint test case on the lead screw of the screw lift.
Further, by matching with the top drive motor being set on the portal frame between several screw lifts
Close the synchronous driving axis connection used.
Further, the screw lift includes the driving nut being set on the portal frame, matches with driving nut
Lead screw using and for setting fixed block is closed, and is additionally provided with the branch being used cooperatively with the lead screw on the portal frame
Arm.
Further, the bottom driving that bottom driving structure drives the operation wheel is provided on the gantry support
Motor.
Further, operation wheel lower section is provided with running track.
Compared with prior art, the utility model realizes the liter of chamber by several screw lifts of synchronization lifting
Drop ensures the stationarity of chamber in lifting process, guarantee test efficiency and experiment accuracy rate.
Description of the drawings
Fig. 1 is one of structural schematic diagram of the embodiments of the present invention.
Fig. 2 is subregional partial enlarged view in the middle part of Fig. 1.
Specific implementation mode
Embodiment：
Refering to fig. 1-2, the present embodiment shows a kind of portal frame elevating translational mechanism：
Including portal frame 1, it is set to the synchronization lifting component 2 at 1 top of portal frame and is set to 1 bottom of portal frame
Operation wheel 3；
Synchronization lifting component 2 includes the uniform several screw lifts 21 being set at the top of portal frame of arranging, is set to silk
The fixed block 22 for joint test case on the lead screw of bar elevator.
It is synchronous by being used cooperatively with the top drive motor 4 being set on portal frame 1 between several screw lifts 21
Drive shaft 41 connects；
The present embodiment is that a kind of 21 distribution form of screw lift is：In four ends of portal frame 1 and two long end sides
Middle part is respectively provided with screw lift 21.
Screw lift 21 include be set on portal frame driving nut 211, with drive nut 211 be used cooperatively and
For setting the lead screw 212 for fixing 22 pieces, and the support arm being used cooperatively with lead screw 212 is additionally provided on portal frame 1.
The bottom driving motor 31 of bottom driving structure driving operation wheel 3 is provided on gantry support 1.
Operation wheel lower section 3 is provided with running track 5.
When the present embodiment does industry, by 22 joint test case 100 of fixed block, after driven by top drive motor 4, pass through
Synchronous drive shaft 41 drives several screw lifts 21 that chamber 100 is driven to be risen, and rear bottom driving motor 31 drives, and leads to
It crosses bottom driving structure driving operation wheel 3 and synchronizes decline after operation in running track 5 reaches corresponding region.
The present embodiment realizes that the lifting of chamber 100, guarantee were lifted by several screw lifts 21 of synchronization lifting
The stationarity of chamber 100 in journey, guarantee test efficiency and experiment accuracy rate.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality
Novel protection domain.
