The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the mounting structure schematic diagram of a kind of towing machine common in prior art;
Fig. 2 and Fig. 3 are the principle schematic of the stressed generation deformation of the cushion blocking of towing machine in prior art;
The structural representation of a kind of towing machine that Fig. 4 provides for the utility model embodiment.
The specific embodiment
Just as described in the background section, shear deformation all easily appears in existing cushion blocking, thereby causes the traction sheave position easily to be offset in the horizontal direction.
The contriver studies discovery, no matter cushion blocking is arranged between load bearing cross beam and traction machine support, or arrange between traction machine support and traction sheave base, or between load bearing cross beam and traction machine support and between traction machine support and traction sheave base, cushion blocking is being set simultaneously, in the vertical direction, the tractive force between traction sheave and track adjusting wheel can make the cushion blocking upper and lower surface be subject to simultaneously the effect of the shearing force of gravity and horizontal direction.
Referring to figs. 2 and 3, the cushion blocking of existing towing machine can be subject to the effect of 4 power, comprising: bearing capacity F1 straight up, pressure F2 straight down, the shearing force F3 of upper surface, the shearing force F4 of lower surface.Wherein, F1 and F2 are conllinear and application force and antagonistic force each other, can not impact Horizontal Deformation.And F3 and F4 are the couple on a pair of horizontal direction, can make upper surface and the lower surface generation shear deformation of cushion blocking, from state shown in Figure 2, become state shown in Figure 3, thereby make the traction sheave occurred level skew of towing machine.As can be known according to above-mentioned analysis, as long as the effect of avoiding the upper and lower surface of cushion blocking to be subject to described couple can avoid it that shear deformation occurs, thereby avoid the traction sheave position to be offset in the horizontal direction.
On basis based on above-mentioned research, the utility model embodiment provides a kind of fixed frame of elevator traction machine, and this fixed frame comprises:
Base of traction machine, traction machine support, load bearing cross beam and cushion blocking, between described base of traction machine and described traction machine support and between described traction machine support and described load bearing cross beam, directly fix, described cushion blocking is arranged on the below at described load bearing cross beam two ends.
Between described base of traction machine and described traction machine support and between described traction machine support and described load bearing cross beam, by check screw, be fixed or be fixed by welding manner.It is above-mentioned fixing that the present embodiment preferably adopts screw to carry out.
The elevator traction machine that adopts described fixed frame to make, owing between described base of traction machine and described traction machine support and between described traction machine support and described load bearing cross beam, directly fixing, the three is as a whole.And the traction sheave and the tractive force between track adjusting wheel that are arranged on described fixed frame are internal force to cushion blocking, cushion blocking only can be subject to straight down pressure and bearing capacity straight up, can not be subject to the effect of horizontal direction power, therefore shear deformation can not occur in cushion blocking, and then avoided the traction sheave position to be offset in the horizontal direction, eliminated potential safety hazard.
The utility model another embodiment provide a kind of elevator traction machine, and with reference to figure 4, this elevator traction machine comprises:
By track adjusting wheel 23, traction sheave 25, the sedan-chair top diversion sheave 26 that steel rope connects successively, fixed frame and as the Capstan rotor of engine installation.
Wherein, described fixed frame comprises: base of traction machine 27, traction machine support 24, load bearing cross beam 22 and cushion blocking 21.Described Capstan rotor is fixed on described traction sheave base on 27, and described traction sheave rotor is connected with described traction sheave 25.Between traction machine support 24 and base of traction machine 27, between traction machine support 24 and load bearing cross beam 22, cushion blocking is not set, directly be fixed.Described cushion blocking 21 is arranged on the below at load bearing cross beam 22 two ends.
The present embodiment, between described traction machine support 24 and base of traction machine 27, between traction machine support 24 and load bearing cross beam 22, the preferred screw that adopts is directly fixed, so that debugging and maintenance after installing.
When the described elevator traction machine of the present embodiment is installed, directly in fixed groove, fix described cushion blocking 21, then load bearing cross beam 22 is placed on described cushion blocking 21, stator wheel 23, traction machine support 24, base of traction machine 27 on described load bearing cross beam, fixing Capstan rotor on described base of traction machine 27, fixing sedan-chair top diversion sheave 26 on car top.
When carrying out traction machine support 24, base of traction machine 27 installation, directly by the hardwired mode of check screw, load bearing cross beam 22, traction machine support 24 and base of traction machine 27 threes are fixing as a whole, without cushion blocking, isolate, install simple, simplify installation procedure, improved installation effectiveness; And without considering, adopt the impact of cushion blocking on the three position, accuracy rate is installed high.
In the use procedure of described towing machine after installation, the tractive force between track adjusting wheel 23 and traction sheave 25 is the internal force between the two, can not tell on to cushion blocking 21.The cushion blocking of the described towing machine of the present embodiment only be subject to straight down pressure and bearing capacity straight up, can not be subject to the effect of horizontal couple of force, therefore avoided cushion blocking generation shear deformation, thereby prevented traction sheave occurrence positions skew in the horizontal direction, eliminated potential safety hazard.
