Abstract

The utility model relates to a hook for loading or unloading weight and relates to a hook for railway freight-car concretely, solving the problem of that a common hook for railway freight-car is unstable when under force, has low carrying capacity and can lift empty wagon only. The hook for railway freight-car comprises a hook body, a hook head and a suspension point, wherein an inner side of the hook head is circular, an end of the hook head which is bladed-shaped bends to a side of the hook body, a horizontal screwed hole is provided on the hook body, a fixed screw bolt comes into the screwed hole from outside to inside. Compared with present technique, the utility model has the advantages of that (1) a force-bearing point can be changed, and the hook is steady and has good security and reasonable structure by equipping the fixed screw bolt and the specially-shaped hook head, (2) the carrying capacity is big, the suspension point and hook body become into an integral body, a focal point of stress of traditional hook is deleted and a freight-car full of goods can be lifted, (3)goods do not need to load or unload thereby time can be saved and intensity of labor can be reduced.

Description

Railway goods loaded vehicle suspension hook

Technical field

The utility model relates to a kind of weight loading and unloading and uses suspension hook, specifically is a kind of railway goods loaded vehicle suspension hook.

Background technology

Railway truck need lorry is moved apart rail, and dead weight of vehicle reaches more than 30 ton usually, is loaded on the goods in it in addition when breaking down, and total weight can reach more than hundred tons basically.L type suspension hook commonly used is reasonable inadequately owing to structure, and when hanging motor vehicle, its hook is in the vehicle side bar, and stress point is changeless, causes load-carrying capacity low, and instability is dangerous big, may not realize that railway carriage and goods hang jointly, so can only hang empty wagons.When using this suspension hook, must with in the railway carriage tens, up to a hundred tons goods unloads, and refills behind the trouble-shooting, certainly will cause the high-intensity work of workman, and lose time, and influences progress.

Summary of the invention

The railway goods loaded vehicle is used the stressed shakiness of suspension hook always to the utility model in the prior art, load-carrying capacity is low in order to solve, and the problem that can only hang empty wagons provides a kind of safety factor height, stability under loading, the railway goods loaded vehicle suspension hook that load-carrying capacity is big.

The utility model adopts following technical scheme to realize: railway goods loaded vehicle suspension hook, comprise coupler body, gib head, suspension centre, and the gib head inboard is a circular arc, its end is the card bladed, and, offer the tapped through hole of level on the coupler body to coupler body one lateral bending song, standing screw from outer to inner penetrates in the tapped through hole.Because gib head inboard be circular-arc, its stress point changes along with the change of the length of standing screw propelling and itself and side bar angle.Standing screw is locked in suspension hook and is hung on the vehicle, and the end is stuck in suspension hook again on the side bar of lorry below for the gib head of card bladed, and double locking strengthens the stability of whole Lift-on/Lift-off System, guarantees safety performance.The suspension centre of placing lifting steel rope or suspender belt is vertical mutually with coupler body, and suspension centre is axially established tapped bore, and tapped bore passes coupler body and forms through hole, and standing screw is through in the tapped through hole.Suspension centre and coupler body are an integral body, and load-carrying capacity is big.Screw thread on the standing screw is saw shape screw thread.

The utility model compared with prior art has following beneficial effect: 1, rational in infrastructure, the setting of standing screw and the gib head of special shape can change stress point, and suspension hook is stable, the safety performance height; 2, load-carrying capacity is big, and suspension centre and coupler body are as a whole, has removed the focal point of stress of traditional suspension hook, can loaded vehicle that fill goods be hung; 3, labor strength is saved time, reduced to the goods of need not removing stage makeup and costume.

Among the figure: 1-standing screw, 2-suspension centre, 3-coupler body, 4-gib head.

The specific embodiment

In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further, embodiment is used for illustrating of the present utility model, rather than it is imposed any restrictions.

Railway goods loaded vehicle suspension hook comprises coupler body 3, gib head 4, suspension centre 2.Gib head 4 inboards are circular arc, and its end is the card bladed, and to coupler body 3 one lateral bending songs, offers the tapped through hole of level on the coupler body 3, and standing screw 1 from outer to inner penetrates in the tapped through hole.Suspension centre 2 is vertical mutually with coupler body 3, and suspension centre 2 is axially established tapped bore, and tapped bore passes coupler body 3 and forms through hole, and standing screw 1 is through in the tapped through hole.Screw thread on the standing screw 1 is saw shape screw thread.

During use, the gib head 4 of four suspension hooks is stuck in the lorry sole bar, rotation standing screw 1 makes itself and lorry closed contact, then steel rope or suspender belt is placed on suspension centre 4 positions, can hang.In addition, four sleeper beam steady braces also can be set up in the suspension hook both sides.

Claims

1, a kind of railway goods loaded vehicle suspension hook, comprise coupler body (3), gib head (4), suspension centre (2), it is characterized in that suspension hook gib head (4) inboard is circular arc, its end is the card bladed, and to coupler body (3) one lateral bending songs, offer the tapped through hole of level on the coupler body (3), standing screw (1) from outer to inner penetrates in the tapped through hole.

2, railway goods loaded vehicle suspension hook according to claim 1 is characterized in that described suspension centre (2) is vertical mutually with coupler body (3), and suspension centre (2) is axially established tapped bore, and tapped bore passes coupler body (3) and forms through hole, and standing screw (1) is through in the tapped through hole.

3, railway goods loaded vehicle suspension hook according to claim 1 and 2 is characterized in that the screw thread on the described standing screw (1) is saw shape screw thread.
