Abstract
The invention relates to the technical field of internal combustion engine supporting devices, in particular to a detachable internal combustion locomotive cowcatcher supporting structure which comprises a beam, an upper hinge base, a lower hinge base, an upper supporting rod and a lower supporting rod. A bolt installation hole is formed in the beam. The lower hinge base is welded to the base. The joint of the upper supporting rod and the lower supporting rod is provided with a rectangular groove. The upper supporting rod and the lower supporting rod are fixedly connected through a square shank bolt and a nut. The upper supporting rod and the lower supporting rod are connected with the upper hinge base and the lower hinge base through an upper hinge bolt and a lower hinge bolt respectively. The upper supporting rod and the lower supporting rod are hollow square steel. The size of the inner edge of the lower supporting rod is equivalent to the size of the outer edge of the upper supporting rod. By means of the structure, the detachable function of the cowcatcher supporting structure is achieved, and a space is provided for locomotive assembling; the length of a cowcatcher supporting rod is adjustable within a certain range, and assembling and adjusting are convenient.
Description
Technical field
The present invention relates to internal combustion engine support meanss technical field, especially a kind of detachable diesel locomotive pilot supports to be tied
Structure.
Background technology
At present, no matter car body bearing-type locomotive or bottom bracket supporting diesel locomotive, its pilot removes leading portion v shape troubleshooting portion
Divide and be fastened on car body with bolt, remainder is all welded on the corresponding position of car body.
The welding of pilot supporting construction is general to be completed with the weldering of body frame group simultaneously, will consider follow-up zero in design
The installing space of part, this often limits the performance of pilot to a certain extent.
And, after body frame group weldering pilot, when locomotive completes assembling, body frame can produce certain amount of deflection, right
Ying Di, can produce unnecessary stress at pilot.
Pilot is the structure in disposable life-span, when locomotive collides, because pilot is welded on body frame, right
Relatively difficult in the maintenance of this part, even and if the safety of second use of pilot also cannot be ensured after keeping in repair.
European standard, for pilot, proposes different design requirements under different speed per hours, and domestic related standard
Require concrete not enough, design also there is uncertainty.Propose a series of detachable pilot of different parameters, both can guarantee that
The traffic safety of locomotive, also can match different pilots according to the speed per hour of locomotive, make cowcatcher design modularity.
Content of the invention
In order to overcome existing deficiency, the invention provides a kind of detachable diesel locomotive pilot supporting construction.
The technical solution adopted for the present invention to solve the technical problems is: a kind of detachable diesel locomotive pilot supports knot
Structure, including crossbeam, upper free bearing, lower free bearing, upper support bar and lower support bar, crossbeam is provided with bolt mounting holes, lower free bearing with horizontal
Beam welds, and upper and lower support bar junction is provided with rectangular channel, is fixedly connected with nut by square shank bolt between upper and lower support bar,
Upper and lower support bar is connected by upper and lower link bolt with upper and lower free bearing respectively.
According to another embodiment of the invention, further include that upper and lower support bar is hollow square steel.
According to another embodiment of the invention, lower support bar inner dimensions and upper support bar physical dimension are further included
Quite.
The invention has the beneficial effects as follows, this device achieves the removable unloading functions of pilot supporting construction, is locomotive assembling
Provide space；The length achieving pilot support bar is adjustable within the specific limits, ease of assembly and regulation.
Brief description
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the scheme of installation of the present invention；
Fig. 3 is rectangular channel partial enlarged drawing.
In figure 1. crossbeam, 2. goes up free bearing, 3. descends free bearing, 4. upper support bar, 5. lower support bar, 6. bolt mounting holes, 7. square
Shape groove, 8. square shank bolt, 9. nut, 10. go up link bolt, 11. times link bolts, 12. supporting mechanisms, 13. car bodies.
Specific embodiment
As shown in Figure 1, Figure 2, Fig. 3 is the structural representation of the present invention, a kind of detachable diesel locomotive pilot supporting construction, bag
Include crossbeam 1, upper free bearing 2, lower free bearing 3, upper support bar 4 and lower support bar 5, crossbeam 1 is provided with bolt mounting holes 6, lower free bearing 3 with
Crossbeam 1 welds, upper 4, lower support bar 5 junction be provided with rectangular channel 7, between upper 4, lower support bar 5 pass through square shank bolt 8 and nut
9 are fixedly connected, upper 4, lower support bar 5 be connected by upper 10, lower link bolt 11 with upper 2, lower free bearing 3 respectively, upper 4, lower support
Bar 5 is hollow square steel, and lower support bar 5 inner dimensions are suitable with upper support bar 4 physical dimension.
Crossbeam 1 is fastened by bolts with car body 13 and couples, and crossbeam 1 side is machined with bolt mounting holes 6, and opposite side corresponds to position
Put processing hole, be using box spanner headspace.
Upper free bearing 2 and car body 13 weld, and lower free bearing 3 and crossbeam 1 weld, upper 4, lower support bar 5 respectively with upper 2, lower free bearing 3
Connected by upper 10, lower link bolt 11.
Upper 4, lower support bar 5 is hollow square steel, and lower support bar 5 inner dimensions are suitable with upper support bar 4 physical dimension, install
When upper support bar 4 insertion lower support bar 5.Upper 4, lower support bar 5 is in junction, and being all machined with pole length direction is in 45 ° of square
Shape groove 7, during installation, upper and lower rectangular channel 7 is in 90 °, can form a square opening, by square shank bolt 8 fastening upper 4, lower support bar
5.The length of rectangular channel 7, ensure that 4, lower support bar 5 has certain displacement in the longitudinal direction, convenient installation.
Described above be merely exemplary for the purpose of the present invention, and nonrestrictive, those of ordinary skill in the art understand,
In the case of the spirit and scope being limited without departing from claims, many modifications, change or equivalent can be made, but all
To fall within the scope of protection of the present invention.
