The mounting device can improve the mounting efficiency of the large-sized ventilator impeller.
Description
Technical field
The utility model relates to a kind of erecting device of large-scale fan impeller, belongs to the technical field of fan impeller erecting device.
Background technique
Impeller needs certain quality of fit requirement as the vitals of ventilator product during installation, thereby needs to adopt reasonable method that draught fan impeller is installed, and avoids causing because of misoperation the damage of draught fan impeller, even damages, and causes and produces waste.The medium and small model of tradition impeller centrifugal or axial fan is installed operation relatively easily, generally can not cause the damage to impeller.The large fan impeller is because boundary dimension is big and heavy, and it is not easy to operate to cause impeller to install, and influences the whole efficiency of assembling of blower fan, and then has influence on manufacturing efficiency.
Summary of the invention
For addressing the above problem, the utility model provides a kind of fan impeller erecting device that improves large fan impeller installation efficiency.
For realizing above-mentioned purpose, the technological scheme that the utility model adopted is:
A kind of fan impeller erecting device; Comprise that the lower end is equipped with the jack of supporting frame; The pull bar lower end of jack is passed supporting frame and is extended downwards with the transmission shaft of fan impeller and is fixedly connected, and dock with the wheel hub upper-end surface of fan impeller the supporting frame lower end surface.
As the further setting of such scheme, be fixed with the external diameter guide cover two identical on the upper-end surface of said transmission shaft with the transmission shaft diameter, the pull bar lower end is fixedly connected with guide cover two.
On the lower end of said pull bar and the top that is positioned at guide cover two is movably installed with guide cover one, and the interference holding is connected between guide cover one and the wheel hub.
Said jack is communicated with the high pressure oil station.
Said jack is connected with manual fluid power booster pump.
A kind of fan impeller erecting device of the utility model; Simple in structure, easy to operate; Can improve large fan impeller installation efficiency; Be applicable to that the transmission shafts head end is shaped as the impeller installation of no thread forms, the jack cylinder size can be selected plurality of specifications according to actual needs for use, to be applicable to the installation to multiple model draught fan impeller.
The utility model cooperates jack and pull bar through supporting frame, accomplishes the installation exercise to fan impeller.The hydraulic pressure that produces through the high pressure oil station orders about the jack effect, axially produces relative displacement, accomplishes the installation exercise to draught fan impeller.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model fan impeller erecting device; Comprise that the lower end is equipped with the jack 13 of supporting frame 11; Pull bar 12 lower ends of jack 13 are passed supporting frame 11 and are extended downwards with the transmission shaft 8 of fan impeller and are fixedly connected, and dock with wheel hub 7 upper-end surfaces of fan impeller supporting frame 11 lower end surfaces.
Wherein, be fixed with the external diameter guide cover two 6 identical with transmission shaft 8 diameters on the upper-end surface of transmission shaft 8, pull bar 12 lower ends are fixedly connected with guide cover 26.On the lower end of the pull bar 12 and top that is positioned at guide cover 26 is movably installed with guide cover 1, and the interference holding is connected between guide cover 1 and the wheel hub 7.Jack 13 is connected with high pressure oil station 1 and manual fluid power booster pump 10.Jack 13 is selected the feedthrough jack for use.
When the utility model carries out the impeller installation exercise,, be connected, form oil hydraulic circuit through the oil pipe 2 of rapid pipe joint 3 with jack 13 oil cylinders through the oil pipe on the high pressure oil station 1.This oil hydraulic circuit also can connect to form through oil pipe 5 with manual fluid power booster pump 10.Pull bar 12 diameter of jack 13 can be carried out processing and fabricating according to the size of different model impeller hub 7; Processing part, the two ends outside thread of pull bar 12; One end and jack 13 adopt nut 14 fastening, and the center screw thread of the other end screw thread and guide cover 26 is with addition of the worker.Guide cover 26 is connected with transmission shaft 8 sections through bolt 9, and the convex portion of guide cover 26 then puts in the transmission shaft 8 end face center holes, should satisfy the design pulling force when wherein bolt 9 is selected for use and check requirement of strength.The wheel hub 7 center end faces of impeller are connected with the supporting frame 11 of jack 13, guide cover 1 and fixedly holding of wheel hub 7, and when supporting frame 11 promotion wheel hubs 7 moved in transmission shaft 8, guide cover 1 also together moved down along pull bar 12.Guide cover one 4 main effects are to guarantee that impeller axially loaded when integral body moves is even, guarantee that simultaneously pull bar 12 center lines and transmission shaft 8 center lines are always on same straight line.Manually fluid power booster pump 10 has mainly been installed the fine adjustment effect to impeller, and the assurance impeller is installed fully, does not have to move axially the gap.Impeller is by after the above-mentioned steps installation; Energized makes jack 13 begin flexible operation by hydraulic pressure, and impeller is producing on pull bar 12 center lines on axial displacement to the transmission shaft 8; When impeller deenergization when the complete installation; Adopt this moment manual fluid power booster pump 10 to accomplish remaining the moving axially of impeller, assurance wheel hub 7 end faces and transmission shaft 8 ladder surfaces are fitted fully, accomplish impeller and install.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
