Abstract
The utility model discloses a drag rod anti-falling structure which solves the problem that an existing drag rod anti-falling structure has potential safety hazards. The drag rod anti-falling structure comprises an anti-disengaging rope, a rope seat and a clamping plate enabling the rope seat to be installed on a drag rod. One end of the anti-disengaging rope is arranged on the rope seat, and the other end of the anti-disengaging rope is used for being connected with a framework or an installation seat of a vehicle body. By means of the drag rod anti-falling structure, when the drag rod is broken, an anti-disengaging steel wire rope installation structure can prevent the drag rod from falling down on a track to cause safety accidents, after the drag rod is separated from the drag seat within a small distance, the steel wire rope can prevent the drag rod from completely falling down, and dragging and braking failures of the drag device are avoided.
Description
Technical field
The utility model relates to a kind of draw bar anti-drop structure, the anticreep steel rope mounting structure of the draw bar of the high or high-speed locomotive steering frame of especially a kind of standard.
Background technology
Draw gear is guideway vehicle and important parts thereof, is mainly used to transmit longitudinal traction power and the braking force of vehicle, also will adapt to the revolution between car body and bogie truck simultaneously.Due to the importance of draw bar, for preventing that draw bar is shed to, on the general draw bar of rail level, anticreep steel rope is all installed and is protected.Conventionally, adopt a kind of simple mounting structure, i.e. welding wire rope erection support on vehicle body bottom frame and truck frame, concentrates but this welding bearing often produces stress.
At present, only 8mm of the wirerope diameter of draw gear, is mainly used in bearing draw bar fracture rear bar weight, and does not consider the impact of bearing after draw bar comes off, and has potential safety hazard; In addition, the installation accessories of steel rope is seldom considered and friction and the noise of draw bar.
Utility model content
In order to overcome existing draw bar disconnecting prevention structure, there is the deficiency of potential safety hazard, the utility model aims to provide a kind of draw bar anti-drop structure, this draw bar anti-drop structure can not only prevent from not being shed on track after draw bar fracture, bears the 30m/s of bogie truck after draw bar comes off
2impact, and can avoid steel rope seat to be directly welded on draw bar, avoid the dry friction of steel rope seat and draw bar and the noise of generation thereof.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of draw bar anti-drop structure, its constructional feature is comprise Anti-rope drop, rope seat and rope seat is contained in to the clamping plate on draw bar; It is upper that one end of described Anti-rope drop is arranged on described rope seat, and the other end of this Anti-rope drop is for being connected with the mount pad of framework or car body.
Welding rope seat on described draw bar can avoid local welding defect to concentrate and crackle etc. as stress.
Be below the technical scheme of further improvement of the utility model:
As a kind of concrete version, described rope seat and clamping plate are connected to form enclosed construction, and this enclosed construction is sleeved on described draw bar.Further, described clamping plate entirety is " Ω " shape.
Further, described rope seat and clamping plate are fixedly linked by fastener.
Between described draw bar and clamping plate, be provided with elastic layer, further, described elastic layer is rubber tie plate.Rubber tie plate can prevent abrasion and the friction noise between clamping plate and draw bar thus, also can play absorbing effect, reaches the effect of protection draw bar.
Preferably, described Anti-rope drop is steel rope, and its diameter is 10mm-24mm, and this overstriking strengthens design, can bear the 30m/s of bogie truck
2impact.
Described anticreep steel rope mounting structure anticreep steel rope mounting structure under draw bar crack conditions can prevent that draw bar from dropping and cause in orbit safety misadventure.
Described draw bar comes off after small distance from traction seat, and steel rope can prevent coming off completely of draw bar, the traction of the draw gear of avoiding and braking failure.
Compared with prior art, the beneficial effects of the utility model are: the utility model makes not to be shed on track after draw bar fracture, and draw bar comes off after a segment distance and still can draw together with steel rope and brake, and has guaranteed the safety in operation of rolling stock; The stress that this structure has been avoided steel rope erection support to be directly welded on and caused on draw bar is concentrated; The dry friction of mounting structure and draw bar and the noise causing thereof have been avoided in the setting of antifriction rubber layer, have protected draw bar.Concrete feature is as follows:
1) rubber tie plate is filled in the gap between clamping plate and draw bar, by hold-down bolt, rubber tie plate, clamping plate and rope seat entirety geometrical clamp are contained on draw bar, on rope seat, safety steel cable is housed, safety steel cable is can wiring seat traversing and rotate, and the safety steel cable other end is arranged on the mount pad of framework or car body.
2) preventing wire rope from falling mounting structure anticreep steel rope mounting structure under draw bar crack conditions can prevent that draw bar from dropping and causes in orbit safety misadventure.
3) draw bar comes off after small distance from traction seat, and safety steel cable can prevent coming off completely of draw bar, the traction of the draw gear of avoiding and braking failure.
4) safety steel cable is that overstriking strengthens design, can bear the 30m/s of bogie truck
2impact.
5) on draw bar, there is no welding wire rope erection support, avoided local welding defect to concentrate and crackle etc. as stress.
6) be provided with rubber tie plate, can prevent abrasion and friction noise between clamping plate and draw bar, also can play absorbing effect, reach the effect of protection draw bar.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
