Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment one
Figure 1 shows that the utility model is arranged on the lower view of the secondary lower beam structure on room-free elevator car frame.This secondary lower beam structure is arranged on bottom lift car, it comprise horizontal arrangement underbeam body 1, be the underbeam body guide wheel assembly 2 of horizontal arrangement and the sedan-chair bottom bracket 3 be fixedly connected with described underbeam body guide wheel assembly 2 with described underbeam body 1 respectively with the second fastener by the first fastener with described underbeam body.
Described first fastener can for the bolt be fixedly connected with on four points with described sedan-chair bottom bracket 3 by described underbeam body 1.And described second fastener is the bolt be fixedly connected with on eight points with the lower surface of described sedan-chair bottom bracket 3 by the end face of described underbeam body guide wheel assembly 2.Such 12 point-supported vibrational power flow instead of traditional underbeam body to six of car supports, increase the bearing surface of cage bottom, thus enhance the stability of car, weaken towing machine work and the shock effect of importing in car.
The straight beam brought in order to the layout solving traditional lower beam structure installs the problem retrodeviated from car center-of-gravity position, and the supporting gravity of the bearing surface that this secondary lower beam structure entirety is formed and car center of gravity coincide.Further, in order to ensure that car center of gravity to drop at the bottom of sedan-chair two and returns on the line between rope sheave, described underbeam guide wheel assembly 2 is arranged in the center-of-gravity position of lift car.Uniform force in the process that the secondary lower beam structure of such layout makes steel rope run at elevator, improves service life of steel wire rope, the traveling comfort of hoisting elevator; Further increase elevator traveling comfort.
Embodiment two
As Fig. 2, described sedan-chair frame comprises above-mentioned secondary lower beam structure, main underbeam 4, two sedan-chair frame straight beams 5.Described secondary lower beam structure and described main underbeam are all arranged on cage bottom, and described secondary lower beam structure and described main underbeam be arranged in parallel.Be arranged on the line of centres of the sedan-chair frame straight beam of main underbeam both sides and car center of gravity on the same line.During embody rule, be arranged on elevator car bottom bracket 3 by described underbeam body 1, car frame underbeam is connected with upper beam by two sedan-chair frame straight beams.The existence of underbeam guide wheel assembly 2 and ten two bearing surfaces of described secondary lower beam structure, increase the bearing surface between lower beam structure and car, thus enhance the stability of car.When elevator is in safety tongs 6 action, because being equipped with the sedan-chair frame of stable secondary lower beam structure, car is made no longer to produce larger overturning couple to car guide rail, vibrations preventing car from producing because of towing machine work and turning on one's side; Meanwhile, uniform force in the process that steel rope runs at elevator, guarantees that car center of gravity drops on the line that to return at the bottom of two sedan-chairs between rope sheave, improves service life of steel wire rope, increase the potential safety hazard of elevator.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
