CN105923515A - Collision bow of elevator car - Google Patents

Abstract

The invention provides a collision bow of an elevator car. The collision bow comprises a collision bow body and a bracket arranged at the lower part of the collision bow. The collision bow body adopts a integrally-formed structure, and comprises a transverse plate and sloping plates arranged at two ends of the transverse plate. The connection parts between the transverse plate and the sloping plates are in circular arc transition. The transverse plate comprises a bottom and a bending part. The bottom is connected with the sloping plates. The bending part is arranged on one side of the bottom, and is perpendicular to the bottom. The bracket is mounted on the bending part. One end of the bracket is connected onto the transverse plate, and a shock pad is arranged at the other end of the bracket. The collision bow is simple in structure; the collision bow body is preferably made of spring steel, and the sloping plates at two ends of the collision bow body have elasticity, and can realize springback, so that the actual use requirements are met; and since the transverse plate and the sloping plates are designed into an integrated structure, the sloping plates cannot shift and fall, are very reliable to use, and are high in stability. Since the sloping plates have a buffering effect, a collision force generated between the collision bow and a travel switch and noise generated in collision are reduced.

Description

A kind of lift car hits bow

Technical field

The invention belongs to elevator parts technical field, especially relates to a kind of lift car and hits bow.

Background technology

In elevator industry, when lift car up close to layer door time, be arranged on car spacing hit bow touching To the travel switch of pre-position, thus cut off elevator fast loop, force deceleration of elevator, by express Slow train is turned to run.Otherwise when express runs down to, the bow plate that hits on car touches precalculated position Travel switch, forces deceleration of elevator, express turn to slow train to run.Make it is to say, hit bow with car Upper and lower vertical movement, when cage operation is to topmost or bottom when exceeding flat bed, hits bow and can rush open Slow down, trigger spacing and limit switch, thus cut off elevator controlling loop, make elevator stop, preventing sedan-chair At the bottom of the crouching of railway carriage or compartment and rush to summit.The existing bow that hits mounts and dismounts inconvenience, is easily damaged.Common bow structure of hitting is Hitting the transverse slat two ends of bow installation elasticity striker individually, owing to elastic striker is split type with transverse slat Structure, it is fixing the most firm easily to occur, easily shifts or comes off, cause job insecurity during use, There is potential safety hazard.

Describe the invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.

A kind of lift car hits bow, as shown in Figures 1 to 4, including hit bow body 1 and its underpart Frame 2；The described bow body 1 that hits is formed in one structure, and it includes transverse slat 3 and the swash plate at transverse slat 3 two ends 4, the two junction arc transition；The two ends of described transverse slat 3 respectively set support 2 described in.Swash plate 4 has There is cushioning effect, alleviate and originally hit impact force and the noise of generation between bow and travel switch.

For avoiding the elbow gradient too big, length of grade is the shortest, causes the travel switch being knocked to send the most audible The shock sound arrived, easily causes misunderstanding and the fear of elevator passenger.Described swash plate 4 and described transverse slat 3 Between angle be 150 °, the length of swash plate can be between 10-20cm.Even if elevator travels speed Reaching more than 1.75m/s, also will not significantly feel noise, ride quality is high.

Wherein, described support 5 one end is connected on described transverse slat 3, the other end be provided with for car Attachment screw that structural member connects and for the cushion 6 of bumper and absorbing shock, can effectively alleviate and hit bow and touch Contact vibrations during travel switch, reduce noise, and effectively extend the service life hitting bow.

Wherein, described cushion 6 is rubber blanket or nylon cushion, and shock-absorbing capacity is good, durable in use.

Wherein, described transverse slat 3 includes the bottom 7 being connected with described swash plate 4 and is in described bottom The bending part 8 of 7 sides；Described bending part 8 is perpendicular to described bottom 7；Described support 5 is arranged on described On bending part 8.Described support 5 entirety is of an L-shaped structure, and it includes integrated bearing 9 and bearing The connecting plate 10 of 9 sides, described bearing 9 is against described bending part 8 near one end of described connecting plate 10 On, described connecting plate 10 is connected by bolt 5 is fixing with described bending part 8.Bearing 9 props up bending Portion 8, bears the load of vertical direction, reliable and stable.

Wherein, state that swash plate 4 is band radian and can the bent plate of resilience.It is pointed out that and hit bow originally Body preferably employs spring steel and makes, and the swash plate 4 at its two ends has elasticity, it is possible to realizes resilience, meets reality The needs that border uses, and owing to transverse slat and swash plate are structure as a whole design, swash plate 4 does not haves displacement Or come off, use very reliable, good stability.

Wherein, the outer surface of described swash plate 4 is provided with smooth wearing layer.This wearing layer can be chromium coating, Swash plate 4 smooth surface, greatly reduces abrasion, and, the chromium coating of setting, durable wear, use Process stabilization is reliable.

The invention simple in construction, reasonable in design, swash plate and transverse slat are integral type structure, do not have Fixing illusive situation, will not shift or come off during use, and stable and reliable in work, swash plate has Cushioning effect, alleviates and originally hits impact force and the noise of generation between bow and travel switch.Support one end is provided with Cushion, can effectively alleviate and hit the vibrations bent when touching travel switch, reduces noise, and effectively prolongs Grow the service life hitting bow.

The foregoing is only the preferred embodiment of the invention, not in order to limit present invention wound Make, within all spirit in the invention and principle, any modification, equivalent substitution and improvement made Deng, within should be included in the protection domain of the invention.
