Abstract
The utility model discloses a novel crown block rail joint, which comprises two butt-joint rails. The two rails are connected together through a connection plate fixed on a rail web; the abutting joint surface of the two rails is a broken section; and a clamping groove cushion plate capable of clamping the rails at the abutting joint is arranged at the lower part of the abutting joint surface of the two rails. By adopting the structure, the abutting joint surface is the broken section, and the advantage that the vibration of a joint with a 45-degree inclined section is low when a wheel passes the joint is reserved, so that the rail surface in the local range of the joint area cannot be pressed and fed, maintenance troubles are avoided, and the problem of high possibility of wearing of a sharp corner is also avoided; simultaneously, because the clamping groove cushion plate is arranged at the lower part of the abutting joint surface, transverse malposition of the two rails at the abutting joint is limited, the abrasion of wheel edges of a crown block is avoided, and the service life of the crown block is prolonged; and the novel crown block rail joint disclosed by the utility model is simple in structure, reasonable in design and smart in conception, completes an effective improvement of the joint with the 45-degree inclined section, fills the blank of similar joints and is worthy of wide popularization and application.
Description
One, technical field
The utility model belongs to overhead traveling crane corollary apparatus technical field, is specifically related to a kind of novel overhead crane orbit joint.
Two, background technology
Overhead traveling crane is the hoisting device commonly used in workshop, supports in orbit by wheel.Track can reach more than the hundreds of rice according to actual needs, needs many tracks to connect.At present, the joint between two tracks adopts straightforward plane tie or 45 ° of oblique section joints usually, namely at first two tracks is adopted straightforward face or 45 ° of oblique sections to dock, then by being linked together by the connecting panel that is bolted on the web of the rail.Overhead traveling crane is in long-term frequent heavily loaded operation, and straightforward plane tie forms straight-through horizontal rail gap between two tracks, the overhead traveling crane wheel by the time vibration big, rail level easily produces and presses feedback in the joint area subrange, during maintenance, repair welding polishes wastes time and energy, repairing effect is also relatively poor; 45 ° of oblique section joints form between two tracks and tiltedly lead to rail gap, wheel by the time vibration little, solved the problem that straightforward plane tie occurs.But 45 ° of wedge angles that rail level forms very easily are worn, and play appears in rail joint, causes the track transversion malposition, has increased the wearing and tearing of overhead traveling crane wheel rim, has reduced the service life of overhead traveling crane.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, reasonable in design, can effectively overcome the novel overhead crane orbit joint of many deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: this joint comprises two tracks that are docking together, and these two tracks link together by the connecting panel that is fixed on the web of the rail; Be characterized in: the interface of two tracks is the folding cross section; Being provided with in the bottom of two orbital docking faces can be with joint track clamping draw-in groove backing plate within it.
Adopt said structure, interface is the folding cross section, kept 45 ° of oblique section joint wheels by the time vibration little advantage, make that rail level can not produce in the joint area subrange to press feedback, avoid the maintenance trouble, the problem that wedge angle very easily is worn can not appear.Simultaneously, owing to be provided with the draw-in groove backing plate in the interface bottom, limit two tracks and transversion malposition occurred at joint, avoided the wearing and tearing to the overhead traveling crane wheel rim, prolonged the service life of overhead traveling crane.The utility model is simple in structure, reasonable in design, is skillfully constructed, and is the effective improvement to 45 ° of oblique section joints, has filled up the blank of this type of joint, is worth applying widely.
Four, description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the lateral plan of Fig. 1.
Five, the specific embodiment
As shown in the figure, the utility model comprises two tracks 1,4 that are docking together, and these two tracks 1,4 link together by the connecting panel 2 that is fixed on the web of the rail.Wherein connecting panel 2 is to be fixed by welding on the web of the rail, adopt this kind welding manner, can actv. avoid screw that bolt brings to the weakening in web of the rail cross section, make the track of joint area under heavy duty wheel pressure, also can not go out fracture, guaranteed the steady-working state of rail joint.Two tracks 1,4 interface are the folding cross section.Being provided with in the bottom of two orbital docking faces can be with joint track clamping draw-in groove backing plate 3 within it.
Claims (2)
1. a novel overhead crane orbit joint comprises two tracks (1,4) that are docking together, and these two tracks (1,4) link together by the connecting panel (2) that is fixed on the web of the rail; It is characterized in that: the interface of two tracks (1,4) is the folding cross section; Being provided with in the bottom of two tracks (1,4) interface can be with joint track clamping draw-in groove backing plate (3) within it.
2. a kind of novel overhead crane orbit joint according to claim 1, it is characterized in that: connecting panel (2) is to be fixed by welding on the web of the rail.
