A kind of elevator traction machine frame
Technical field
This utility model relates to elevator technology field, a kind of elevator traction machine frame for fixing traction machine.
Background technology
When elevator design, the vibration influence surrounding produced during for reducing traction machine operating and elevator itself, need to install damper element additional.General damper element is arranged between traction machine and frame, but owing to the special tectonic (such as traction sheave is not in the structure at traction machine center) of traction machine causes the damper element under traction machine to need different elastic modelling quantity, not so traction machine can tilt.And general damper element can not tension, if traction machine is axially having torsion, then damper element may disabling damage, even result in toppling over of traction machine.
Summary of the invention
In view of this, the purpose of this utility model is the defect in order to overcome prior art, it is provided that noise that environment is caused by a kind of vibrations reducing traction machine and vibrations, and avoids the most firm safe elevator traction machine frame that traction machine topples over.
For reaching above-mentioned purpose, this utility model provides a kind of elevator traction machine frame, including the frame beam for fixing traction machine, it is characterized in that: on the both ends of its length of described frame beam, be respectively equipped with shock-absorbing support part, the shape of cross section of described frame beam is I-shaped, it has upper backup pad and lower supporting plate, the width of described upper backup pad is more than the width of described lower supporting plate, described shock-absorbing support part has opening up groove, described lower supporting plate extend downwardly into described groove and be supported on described groove bottom surface on, on the opening both sides of the described groove that the both ends correspondence of the width of described upper backup pad is supported on described shock-absorbing support part.
Preferably, it is additionally provided with damper element between described frame beam and described shock-absorbing support part, described damper element includes the lower floor's damper element being arranged between the bottom surface of described lower supporting plate and described groove, is separately positioned on the upper strata damper element between the opening both sides of the both ends of the width of described upper backup pad and the described groove of correspondence.
As a kind of embodiment, the shape of cross section of described shock-absorbing support part is C-shaped, and the both sides of its upper opening are respectively provided with the bending edge of fold inward.
As another embodiment, the shape of cross section of described shock-absorbing support part is U-shaped, and the both sides of its upper opening are respectively provided with the bending edge of outwards turnover.
Compared to prior art, elevator traction machine frame of the present utility model has the advantage that
(1) traction machine is directly connected to frame beam, at frame beam two ends, shock-absorbing support part is set, damper element is placed between frame beam and shock-absorbing support part, under traction machine, directly place damper element relative to prior art and can reduce the torque suffered by damper element, effectively reduce traction machine and environment is caused noise, vibrations.
(2) damper element of both sides, frame beam width direction by changing its size, can easily change the elastic modelling quantity of two damper elements, makes traction machine to tilt.
(3) in further improving, damper element is divided into upper strata damper element and lower floor's damper element, the design of this double-layer shock-absorbing element can prevent frame beam from axially toppling over, and makes traction machine install more firm.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
Embodiment one
Refer to Fig. 1 and 5, a kind of elevator traction machine frame, including the frame beam 2 for fixing traction machine 1, shock-absorbing support part 3 it is respectively equipped with on the both ends of its length of frame beam 2, the shape of cross section of frame beam 2 is I-shaped, it has upper backup pad 21 and lower support 22, the width of upper backup pad 21 is more than the width of lower supporting plate 22, shock-absorbing support part 3 has opening up groove 31, lower supporting plate 22 extend downwardly into groove 31 and be supported on groove 31 bottom surface on, on the opening both sides of the groove 31 that the both ends correspondence of the width of upper backup pad 21 is supported on shock-absorbing support part 3.
In the present embodiment, the shape of cross section of shock-absorbing support part 3 is C-shaped, and the both sides of its upper opening are respectively provided with the bending edge 32 of fold inward.It is additionally provided with damper element between frame beam 2 and shock-absorbing support part 3, described damper element includes the lower floor's damper element 41 being arranged between the bottom surface of lower supporting plate 22 and groove 31, it is separately positioned on the upper strata damper element 42 between the opening both sides of the both ends of the width of upper backup pad 21 and the groove 31 of correspondence, as shown in Figure 5.Damper element can be rubber or other non-metal elastomers.
In the elevator traction machine frame of the present embodiment, owing to traction machine 1 is directly connected to frame beam 2, the damper element 41,42 that cushioning effect is mainly reflected between frame beam 2 two ends and shock-absorbing support part 3, under traction machine, directly place damper element relative to prior art and can reduce the torque suffered by damper element, effectively reduce traction machine and environment is caused noise, vibrations.It addition, the damper element 41,42 of frame beam 2 width both sides by changing its size, can easily change the elastic modelling quantity of two damper elements 41,42, traction machine 1 is made to tilt.Furthermore, damper element is divided into upper strata damper element 42 and lower floor's damper element 41, the design of this double-layer shock-absorbing element can prevent frame beam 2 from axially toppling over, make traction machine 1 install more firm.
During installation, elevator traction machine frame of the present utility model can be supported directly on the reserving hole of well enclosure 100, as shown in Figure 2 by shock-absorbing support part 3.Or, elevator traction machine frame of the present utility model is directly anchored to guide rail 200 upper end, as shown in Figure 3 by shock-absorbing support part 3.Again or, elevator traction machine frame of the present utility model by shock-absorbing support part 3 and is supported the hoistway of shock-absorbing support part 3 is set a roof beam in place and 300 is arranged on the reserving hole of well enclosure 100, as shown in Figure 4.
Embodiment two
The present embodiment is with the difference of embodiment one: the shape of cross section of shock-absorbing support part 3 is U-shaped, and the both sides of upper opening are respectively provided with the bending edge 33 of outwards turnover, are used for placing upper strata damper element 42 and carry out frames beam 2.
Above-described embodiment is only for illustrating technology of the present utility model design and feature; its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this; protection domain of the present utility model can not be limited with this; all equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
