Abstract

A kind of convex straight beam fixing for sedan-chair frame, including straight beam, straight beam is divided into mid portion and two two end portions, mid portion is flat type crossbeam form, each two end portions structure is identical, all includes changeover portion and rear cross, and changeover portion connects the end of mid portion and the front end of rear cross, changeover portion, horizontal by tilting 25 ° ~ 35 ° placements, is all arranged in 145 ° ~ 155 ° with mid portion and rear cross.This design can prevent the sedan-chair arm and straight beam continuous frictional impact in elevator operation, all serve, to straight beam and sedan-chair arm, the effect of being effectively protected so that maintaining surplus between the sedan-chair arm of straight beam and sedan-chair frame after sedan-chair frame is fixed.

Description

A kind of convex straight beam fixing for sedan-chair frame
Technical field
The present invention relates to the device of elevator zero device formation technical field is and in particular to a kind of convex fixing for sedan-chair frame Straight beam.
Background technology
In recent years, with the continuous improvement of people's living standard, high buildings and large mansions get more and more, and its height also rises higher and higher, No matter being therefore to add between neighbours living much liftable lift facility in megastore or all.Elevator is people's More and more extensive and important effect is played in daily life.The various performances of elevator not only affect the life of people, and Also closely bound up with the life security of people.Therefore, the various performances of hoisting elevator, Ji Yaobao should be made great efforts in elevator manufacturer The usual normal operation of card elevator, also can will effectively reduce the loss of elevator part in the design.
For example in the straight beam fixing to sedan-chair frame, because straight beam is flat type, straight beam and sedan-chair frame in the operation of elevator Sedan-chair arm can produce collision friction, thus certain loss all can be produced to straight beam and sedan-chair arm, therefore, elevator manufacturer need right On the one hand this do more improvement, thus eliminating this potential safety hazard on elevator.
Therefore, the problems referred to above are the problems that should pay attention to during the design and use to straight beam and solve.
Content of the invention
For above-mentioned problem, the present invention provides a kind of convex straight beam fixing for sedan-chair frame.
The technical solution of the present invention is:A kind of convex straight beam fixing for sedan-chair frame, including straight beam, described straight beam divides For mid portion and two two end portions, described mid portion is flat type crossbeam form, each described two end portions structure phase Same, all include changeover portion and rear cross, described changeover portion connects the end of described mid portion and the front end of rear cross, institute State changeover portion horizontal by tilting 25 ° ~ 35 ° placements, all set in 145 ° ~ 155 ° with described mid portion and described rear cross Put.
Further improvement of the present invention is:Described mid portion adopts moulding process one to become with described two end portions Type.
Further improvement of the present invention is:The both sides of described straight beam adopt bending technique to form flanging so that described straight The U-shaped structure of beam.
A kind of convex straight beam fixing for sedan-chair frame of the present invention, straight beam left side to straight beam first in the case that entirety is straight Right both sides carry out bending process and form flanging so that the overall u-shaped structure of straight beam.Then straight beam integrally adopts moulding process one Body formed so that straight beam mid portion protrudes, the two ends of straight beam make straight beam two ends form falling tendency, transition using changeover portion Section end is straight rear cross again, and symmetrically, two changeover portions and mid portion form same angle setting for straight beam both sides, Two rear cross 4 are in parallel with the mid portion 1 of straight beam.
The invention has the beneficial effects as follows:To be used for being designed as centre to the fixing straight beam of sedan-chair frame from traditional overall flat type Partly raised form, can prevent so that maintaining surplus between the sedan-chair arm of straight beam and sedan-chair frame therefore after sedan-chair frame is fixed Only sedan-chair arm and straight beam continuous frictional impact in elevator operation, to each producing damage.The straight beam left and right sides adopts bending Process, enhance the intensity of straight beam.Present configuration is simple, easy for installation, and while can guarantee that elevator normal operation Also remain the surplus between straight beam and sedan-chair arm, the effect of being effectively protected all is served to straight beam and sedan-chair arm.
Brief description
Fig. 1 is a kind of partial structural diagram of the convex straight beam fixing for sedan-chair frame of the present invention.
Fig. 2 is a kind of positive structure schematic of the convex straight beam fixing for sedan-chair frame of the present invention.
Wherein, 1- mid portion, 2- two end portions, 3- changeover portion, 4- rear cross, 5- flanging.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is done and retouch in detail further State, this embodiment is only used for explaining the present invention, protection scope of the present invention is not constituted and limits.
As depicted in figs. 1 and 2, the present embodiment provides a kind of convex straight beam fixing for sedan-chair frame, including straight beam, described straight Beam is divided into mid portion 1 and two two end portions 2, and described mid portion 1 is flat type crossbeam form, each described two end portions 2 structures are identical, all include changeover portion 3 and rear cross 4, and the end that described changeover portion 3 connects described mid portion 1 is horizontal with rear portion The front end of beam 4, described changeover portion 3 is placed horizontal by tilting 25 ° ~ 35 °, preferably 30 °, with described mid portion 1 and institute State rear cross 4 all to arrange in 145 ° ~ 155 °, preferably 150 °.Described mid portion 1 and described two end portions 2 adopt molding Technique is integrally formed.The both sides of described straight beam adopt bending technique to form flanging 5 so that the U-shaped structure of described straight beam.
A kind of convex straight beam fixing for sedan-chair frame of the present embodiment, straight beam is first in the case that entirety is straight to straight beam The left and right sides carries out bending process and forms flanging 5 so that the overall u-shaped structure of straight beam.Then straight beam integrally adopts molding work Skill is integrally formed so that straight beam mid portion 1 protrudes, and the two ends of straight beam make the formation downslide of straight beam two ends become using changeover portion 3 Gesture, changeover portion 3 end is straight rear cross 4 again, and symmetrically, two changeover portions 3 and mid portion 1 form same for straight beam both sides One angle setting, two rear cross 4 are in parallel with the mid portion 1 of straight beam.
The beneficial effect of the present embodiment is:To be used for the fixing straight beam of sedan-chair frame from traditional overall flat type is designed as Between partly raised form, therefore after sedan-chair frame is fixed can so that maintaining surplus between the sedan-chair arm of straight beam and sedan-chair frame, Prevent the sedan-chair arm and straight beam continuous frictional impact in elevator operation, to damage each can be produced.The straight beam left and right sides is using folding Crook is managed, and enhances the intensity of straight beam.Present configuration is simple, easy for installation, and can guarantee that the same of elevator normal operation When also remain surplus between straight beam and sedan-chair arm, the effect of being effectively protected all is served to straight beam and sedan-chair arm.
