Abstract
The utility model provides a hold-down mechanism of a shock absorber for a draught fan in an air-handling unit. The shock absorber is mounted between the draught fan and a mounting base. The hold-down mechanism is characterized by comprising a compression beam and a fastening component. The compression beam is arranged between the draught fan and the shock absorber. The fastening component penetrates through the compression beam and the mounting base in a connected mode so as to adjust the compression deformation quantity of the shock absorber. The hold-down mechanism can be used for protecting the shock absorber for the draught fan in the transportation process of the air-handling unit.
Description
Technical field
The utility model relates to a kind of transportation fender guard of air-treatment unit, is specifically related to the hold-down mechanism that a kind of air-treatment unit apoplexy machine is used bumper.
Background technology
The air-treatment unit generally comprises blower fan, temperature booster or the constituent elementss such as cooling vessel and filter.Its groundwork process is: the outdoor new wind that comes is with after indoor a part of return air mixes, after the process filter filters the objectionable impuritiess such as airborne dust, flue dust and organic filler, cleaned air is delivered to cooling vessel or temperature booster through blower fan and is cooled off or heat, and sends into the room after reaching predetermined temperature.
At present the assembling of air-treatment unit mostly adopts base plate is installed in mode on the mounting seat by bumper.Be connected by bumper between blower fan and the mounting seat in this mounting means, for example adopt spring damper.In air-treatment unit blower fan transportation, mounting seat is placed in the casing down and transports, owing to jolting, pass the reasons such as sloping road in the transportation, above-mentioned bumper can be subject to larger impact or be subject to horizontal stress, usually cause occurring in the transportation phenomenons such as bumper gross distortion, destruction, even further damage blower fan, cause direct economic loss and the wasting of resources.
The utility model content
The utility model provides the hold-down mechanism of a kind of air-treatment unit apoplexy machine with bumper, is used for the protection that air-treatment unit transportation blower fan is used bumper.
The air-treatment unit apoplexy machine that the utility model the provides hold-down mechanism of bumper, its bumper is installed on the mounting seat, blower fan is positioned at bumper top, described hold-down mechanism comprises compression beam and fastening assembly, compression beam is arranged between blower fan and the bumper, fastening assembly runs through and connects compression beam and mounting seat, to regulate bumper compressed shape variable.Thereby forward and backward in the transportation of air-treatment unit, can and discharge the bumper compression, in transportation, to protect bumper.
A via hole is respectively offered at described compression beam two ends, and mounting seat is offered respectively via hole corresponding to the position of compression beam via hole; Fastening assembly comprises lock bolt and locknut, and lock bolt passes via hole corresponding on compression beam and the mounting seat, is used with locknut.When the air-treatment unit is prepared transportation; by the rotational lock bolt bumper is compressed to its maximum compression deformation quantity; present rigidly connected characteristics, the contrarotation lock bolt made bumper recover its normal deformation after transportation was finished, thus protection bumper in transit.
Preferably, described compression beam adopts U-shaped steel or channel-section steel, in order to be installed between bumper and the blower fan, is convenient to simultaneously offer via hole at its two ends.
Described bumper is spring damper or rubber absorbers, changes distance between compression beam and the mounting seat by fastening assembly, is positioned at both middle spring dampers or the compressed shape variable of rubber absorbers with adjusting.
Preferably, described hold-down mechanism is two groups, is arranged at respectively the both sides of blower fan.At first two compression beam are arranged on the bumper, then blower fan are installed on two compression beam, so that the bumper of blower fan is stressed evenly in the air-treatment unit transportation, thereby protect better bumper in transit.
Description of drawings
Fig. 1 is the structural representation that air-treatment unit apoplexy machine provided by the utility model is used the hold-down mechanism of bumper.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in detail to the utility model.
As shown in Figure 1, the air-treatment unit apoplexy machine that the utility model provides comprises compression beam 41 and fastening assembly with the hold-down mechanism of bumper, wherein compression beam 41 is arranged at two bumper 2 tops, and bumper 2 is installed on the mounting seat 3, and compression beam 41 can pasted blower fan 1 bottom and arranged.At least one via hole is respectively offered at compression beam 41 two ends, mounting seat 3 corresponding to the position of via hole on the compression beam 41 respectively correspondence offer via hole.Fastening assembly comprises lock bolt 42 and locknut, and both are used.Lock bolt 42 passes via hole corresponding on compression beam 41 and the mounting seat 3 from the top of compression beam 41 via holes, the lower surface that locknut is installed in mounting seat 3 screws in lock bolt 42.
When the air-treatment unit is prepared transportation, rotational lock bolt 42 moves to the locknut direction, the distance that drives between compression beam 41 and the mounting seat 3 diminishes gradually, thereby make the compression set of the bumper between compression beam 41 and mounting seat 3 increasing, force bumper to be pressed onto extreme lower position, present rigidly connected state, keep the shock-absorbing function of bumper.
When the air-treatment unit arrives the erecting stage, contrarotation lock bolt 42, the distance that drives between compression beam 41 and the mounting seat 3 progressively increases, and is positioned at both compression sets of middle bumper and returns to gradually normal deformed state, discharges the shock-absorbing function of bumper.
Above-mentioned hold-down mechanism can adopt two groups, is arranged at respectively the both sides of blower fan 1.At first two compression beam 41 are installed on bumper 2 tops; blower fan 1 is installed on two compression beam 41; then install and amount to four groups of fastening assemblies at the via hole place on the via hole at two compression beam 41 two ends and corresponding mounting seat 3 respectively; so that the bumper of blower fan is stressed evenly in the air-treatment unit transportation, protect better bumper in transit.
Above-mentioned bumper 2 can be spring damper or rubber absorbers, changes distance between compression beam 41 and the mounting seat 3 by fastening assembly, is positioned at both middle spring dampers or the compressed shape variable of rubber absorbers thereby regulate.
Described compression beam adopts U-shaped steel or channel-section steel, with taking off of being installed in easily between bumper 2 and the blower fan 1 and having transported.
The utility model is not limited to above-mentioned concrete embodiment, and for example above-mentioned lock bolt 42 also can pass from the bottom of mounting seat 3 via holes via hole corresponding on mounting seat 3 and the compression beam 41, and locknut is installed in the upper surface of compression beam 41.Described those skilled in the art are from above-mentioned design, without performing creative labour, any modification of doing, are equal to replacement, improvement etc., all drop within protection scope of the present invention.
