Abstract
The utility model discloses a core plate for a tunnel locomotive, which comprises a lower core plate, a core plate oil basin and an upper core plate, wherein a core plate bolt is arranged at the center of a lower core plate, a plurality of lubricating grooves are distributed on the lower core plate to improve lubricating capacity and bearing capacity of the core plate, the core plate can bear larger cavity, and a side brace only has an auxiliary function. Contact planes of the core plate are replaced by spherical surfaces so that traction force can be transferred through the action force between the spherical surfaces. Even through the contact surface is abraded, good contact between the spherical surfaces can be kept, and a traction function can be achieved well. The core plate bolt is arranged between the upper core plate and the lower core plate to enable the upper core plate and the lower core plate to be connected together serially, the lower end of the bolt is welded with the lower core plate in a sealed mode, and the upper end of the bolt is connected with an upper core plate nut to limit a movement range of the upper core plate to perform secondary protection on a structure. Clearance among the core plate bolt, the nut and the upper core plate is large so that relative rotation of the upper core plate and the lower core plate is not hindered within a certain range.
Description
Technical field:
The utility model relates to a kind of mechanism that connects locomotive and bogie truck.Particularly be applied to the core dish structure of tunnel hauling engine.
Background technology:
General locomotive core dish only transmits longitudinal force and transverse force, needs the other support structure of comparatively complicated contact to bear vehicle body gravity.The conventional core dish leans on towing pin side transmitting tractive power, and this structure is higher to the requirement of strength of pin, and it is bigger to wear and tear.Abominable for tunnel construction environment, the derailed phenomenon of locomotive is more, and is higher to the security requirement of core dish.
The utility model content:
The utility model proposes a kind of tunnel locomotive core dish to the problem and shortage that exists in the present prior art.
The technical scheme that the utility model adopted: a kind of tunnel locomotive core dish, comprise down core dish, core dish oil tray, go up the core dish, following core disk center is provided with core valve snail bolt, and last core disk center is installed on this bolt and through the core valve snail is female to be fixed.
Upper and lower core dish contact surface is a sphere, promptly in following core dish upper center spherical groove is set, and last core dish downside center is provided with sphere, this sphere and spherical groove coupling.
Arrange many lubrication grooves at following core dish.
The structure of lubrication groove is uniformly distributed with between the two annular lubrication grooves and is communicated with many lubrication grooves of radially dispersing for ring lubrication groove and outer shroud lubrication groove in the chip bolt outside is provided with respectively.
Core dish oil tray and following core dish tight weld, oil tray internal grease liquid level height and sphere.
Core valve snail bolt, core valve snail female all with last core dish free-running fit.
The utility model good effect: this core dish is arranged many lubrication grooves at following core dish, has increased the lubricating power of core dish, has improved the load-carrying capacity of core dish, and the core dish can carry bigger gravity, and booster action is only played in other support.The design changes core dish contact level into sphere, utilizes the force transmission tractive force between the sphere.Even there are wearing and tearing in contact surface, still can keep between the sphere contacting preferably, accomplish traction function preferably.Setting up core valve snail bolt between the core dish up and down.Core valve snail bolt two core dishes up and down is chained together, bolt lower end and following core dish tight weld; The bolt upper end is connected with last core valve snail is female, and the action radius of core dish in the restriction is carried out second protection to structure; The gap of core valve snail bolt, nut and last core dish is bigger, does not hinder relatively rotating of upper and lower core dish within the specific limits.
Description of drawings:
Fig. 1 is the utility model perspective view;
Fig. 2 is following core dish structural representation;
Fig. 3 is the A-A cross-sectional view of Fig. 2;
Fig. 4 goes up core dish structural representation;
Fig. 5 is the B-B cross-sectional view of Fig. 4.
The specific embodiment:
Referring to Fig. 1-Fig. 5, this core dish is arranged many lubrication grooves 8 at following core dish 1, has increased the lubricating power of core dish, has improved the load-carrying capacity of core dish, and the core dish can carry bigger gravity, and booster action is only played in other support.The design changes core dish contact level into sphere, utilizes the force transmission tractive force between the sphere.Even there are wearing and tearing in contact surface, still can keep between the sphere contacting preferably, accomplish traction function preferably.Setting up core valve snail bolt 4 between the core dish up and down.Core valve snail bolt 4 two core dishes up and down is chained together, bolt lower end and following core dish tight weld; Bolt 4 upper ends are connected with last core valve snail female 5, and the action radius of core dish in the restriction is carried out second protection to structure; The gap of core valve snail bolt 4, nut 5 and last core dish is bigger, does not hinder relatively rotating of upper and lower core dish within the specific limits.
Core dish oil tray 2 and following core dish 1 tight weld, oil tray 2 internal grease liquid level height and spheres, grease play the effect of lubricated cooling.
In use, last core dish 3 is connected with car body, and following core dish 1 is connected the other support in the left and right sides with bogie truck can the wiggly degree of freedom of killer; Core dish combined action on former and later two bogie trucks can limit the degree of freedom that it rocks back and forth; So the actual core disc that uses only can rotate around vertical direction.
In the distraction procedure, the tractive force of bogie truck mainly transmits through core dribbling face application force up and down, and core valve snail nail only plays a protective role.
Following core dish 1 is captiveed joint with bogie truck through bolt, and following core dribbling face is to recessed, is being uniformly distributed with lubrication groove on the sphere with contacting of last new building.Play the effect of lubricating contact face.
Claims (6)
