Abstract

The invention discloses a convex type straight beam. The convex type straight beam comprises a straight beam body, wherein the straight beam body is divided into a middle part and two end parts; the middle part is in the form of a flat and straight cross beam; the two end parts are the same in structure; each end part comprises a transition section and a rear-part cross beam; the transition section is connected with the tail end of the middle part and the front end of the rear-part cross beam; an inclination angle of 25 to 35 degrees is formed between the transition section and the horizontal plane; an inclination angle of 145 to 155 degrees is formed between the middle part and the rear-part cross beam. Due to the fact that the design is adopted, after a car frame is fixed, a clearance can be reserved between the straight beam and a car arm of the car frame, continuous friction and collision between the car arm and the straight beam during operation of an elevator are prevented, and the straight beam and the car arm are effectively protected.

Description

A kind of convex straight beam
Technical field
The present invention relates to the device of elevator zero device formation technical field, be specifically related to a kind of convex straight beam.
Background technology
In recent years, along with improving constantly of people's living standard, high buildings and large mansions get more and more, and it highly also rises higher and higher, no matter are therefore in megastore or between neighbours living, all add a lot of liftable lift facility.Elevator plays a part more and more extensive and important in daily life.The various performances of elevator not only affect the life of people, but also closely bound up with the life security of people.Therefore, the various performances of hoisting elevator should be made great efforts in elevator manufacturer, the normal operation that elevator is usual should be ensured, also want the loss that effectively can reduce elevator part in the design.
Such as at the straight beam fixed sedan-chair frame, because straight beam is flat type, in the operation of elevator, the sedan-chair arm of straight beam and sedan-chair frame can produce collision friction, thus all can produce certain loss to straight beam and sedan-chair arm, therefore, more improvement need be done on the one hand to this by elevator manufacturer, thus eliminates this potential safety hazard on elevator.
Therefore, the problems referred to above should be paid attention to and the problem solved in the design and use process of straight beam.
Summary of the invention
For above-mentioned Problems existing, the invention provides a kind of convex straight beam.
Technical solution of the present invention is: a kind of convex straight beam, comprise straight beam, described straight beam is divided into centre portion and two two end portions, described centre portion is flat type crossbeam form, each described two end portions structure is identical, includes transition phase and rear cross, and described transition phase connects the end of described centre portion and the front end of rear cross, described transition phase, horizontal by inclination 25 ° ~ 35 ° placements, is all arranged in 145 ° ~ 155 ° with described centre portion and described rear cross.
Further improvement of the present invention is: described centre portion and described two end portions adopt forming process one-body molded.
Further improvement of the present invention is: the both sides of described straight beam adopt bending technique to form flanging, make described straight beam be U-shaped structure.
A kind of convex straight beam of the present invention, first straight beam carries out bending process when entirety is straight to the left and right sides of straight beam and forms flanging, makes overall straight beam be U-shaped structure.Then straight beam entirety adopts forming process one-body molded, straight beam centre portion is protruded, the two ends of straight beam adopt transition phase to make straight beam two ends form falling tendency, transition phase end is again straight rear cross, straight beam both sides are symmetrical, two transition phases and centre portion form same angle and arrange, and two rear cross 4 are parallel with the centre portion 1 of straight beam.
The invention has the beneficial effects as follows: the form straight beam being used for fixing sedan-chair frame being designed to centre portion projection from traditional overall flat type, therefore can make to maintain surplus between the sedan-chair arm of straight beam and sedan-chair frame after being fixed sedan-chair frame, prevent sedan-chair arm and the straight beam continuous frictional impact when elevator operation, to all damage being produced separately.The straight beam left and right sides adopts bending process, enhances the intensity of straight beam.Structure of the present invention is simple, easy for installation, and while ensureing elevator normal operation, also remain the surplus between straight beam and sedan-chair arm, all serves actv. protective effect to straight beam and sedan-chair arm.

Fig. 1 is the local structure schematic diagram of a kind of convex straight beam of the present invention.
Fig. 2 is the Facad structure schematic diagram of a kind of convex straight beam of the present invention.
Wherein, 1-centre portion, 2-two end portions, 3-transition phase, 4-rear cross, 5-flanging.
Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
As depicted in figs. 1 and 2, the present embodiment provides a kind of convex straight beam, comprise straight beam, described straight beam is divided into centre portion 1 and two two end portions 2, described centre portion 1 is flat type crossbeam form, each described two end portions 2 structure is identical, include transition phase 3 and rear cross 4, described transition phase 3 connects the end of described centre portion 1 and the front end of rear cross 4, described transition phase 3 is horizontal by inclination 25 ° ~ 35 ° placements, be preferably 30 °, all arrange in 145 ° ~ 155 ° with described centre portion 1 and described rear cross 4, be preferably 150 °.Described centre portion 1 and described two end portions 2 adopt forming process one-body molded.The both sides of described straight beam adopt bending technique to form flanging 5, make described straight beam be U-shaped structure.
A kind of convex straight beam of the present embodiment, first straight beam carries out bending process when entirety is straight to the left and right sides of straight beam and forms flanging 5, makes overall straight beam be U-shaped structure.Then straight beam entirety adopts forming process one-body molded, straight beam centre portion 1 is protruded, the two ends of straight beam adopt transition phase 3 to make straight beam two ends form falling tendency, transition phase 3 end is again straight rear cross 4, straight beam both sides are symmetrical, two transition phases 3 form same angle with centre portion 1 and arrange, and two rear cross 4 are parallel with the centre portion 1 of straight beam.
The beneficial effect of the present embodiment is: the form straight beam being used for fixing sedan-chair frame being designed to centre portion projection from traditional overall flat type, therefore can make to maintain surplus between the sedan-chair arm of straight beam and sedan-chair frame after being fixed sedan-chair frame, prevent sedan-chair arm and the straight beam continuous frictional impact when elevator operation, to all damage being produced separately.The straight beam left and right sides adopts bending process, enhances the intensity of straight beam.Structure of the present invention is simple, easy for installation, and while ensureing elevator normal operation, also remain the surplus between straight beam and sedan-chair arm, all serves actv. protective effect to straight beam and sedan-chair arm.
