When pantograph is in chopper bar position, the auxiliary rising bow jacking mechanism be located at the upper push pipe of frame in pantograph just under
Side, upper push pipe are directly contacted with the supporting block.
The present invention provides a kind of pantographs to assist rising bow jacking mechanism, is mounted on the assembling of pantograph chassis by bolt
On, supporting block directly acts in pantograph push pipe on frame, guarantees pantograph in initial rising bow state, in support rod maximum
Jack-up active force is always maintained to upper push pipe in stroke range, in the condition for not influencing pantograph other performances and application safety
Under, the initial rising bow lifting force of pantograph is increased, it can not rising bow failure caused by reducing pantograph due to bow body bonding
Rate.
It should be noted that "upper" "lower" mentioned herein is not specific to the direction except specified otherwise, it is intended merely to
Description is convenient, its different description of the position of the product is not also identical.Those of ordinary skill in the art are not making creativeness
Intelligible orientation under labour precondition belongs to the scope that the present invention protects.
Specific embodiment：
As shown in Figures 1 to 4, pantograph auxiliary rising bow jacking mechanism includes supporting block 1, support rod 2, box body 3, compression bullet
Spring 4, sliding block 5, nut 6.
The supporting block 1 is nonmetallic software material, and the materials such as rubber, nylon can be used, and guarantees the fast prompt drop bow of pantograph
When supporting block will not to contact site bend body surface face paint generate damaging influence；Supporting block 1 is internally embedded installation in M8
The metal mounting flange of threaded hole, metal mounting flange are usually stainless steel material；
The support rod 2 is round steel section form, and stainless steel can be used and be integrally machined molding, both ends are used equipped with M8 external screw thread
In connection and fastening with supporting block 1 and sliding block 5；There are boss for the processing of support rod 2 inside box body 3, are used to support bar
Maximum jacks up the positioning of limit and the sliding block installation of stroke；
The box body 3 is stainless steel material, and top processes 8 through-hole of ￠ and 2 outer diameter of support rod forms clearance fit, guarantees branch
The concentricity of strut 2 and 3 inner cavity of box body；Inner cavity aperture and sliding block outer diameter form clearance fit, are further ensured that support rod 2 and box
The concentricity of 3 inner cavity of body；3 bottom of box body is equipped with mounting flange and 4 mounting holes, and mounting flange can pass through welding or box body one
Body machine-shaping；The depth of 3 inner cavity of box body should ensure that the range and compressed spring elastic force anti-attenuation of support rod 2；
The compressed spring 4, be it is spiral, plane is processed at both ends, be vertically disposed in 3 lumen centers position of box body, one
5 inside grooves of sliding block are held and are embedded in, the other end is directly placed on pantograph underframe support plate；The stiffness K value of compressed spring 4
Setting should fully consider pantograph chopper bar retentivity, it is as big as possible when not influencing chopper bar retentivity standard requirements value；Compression
The free extension length of spring 4 will guarantee that support rod 2 elastic always can act on sliding block before jacking up to maximum height；
The sliding block 5, in order to which support rod 2 can pass through sliding block 5, centre is machined with 8 through-hole of ￠, contacts with compressed spring 4
One end processing is fluted, and for the depth of groove within the scope of 1~2mm, the internal diameter of groove suggests big 0.5~1mm than compressed spring；It is sliding
Block is connect and is fastened with support rod 2 by M8 nut；
As shown in Fig. 2, pantograph assists rising bow jacking mechanism to be fixed on pantograph chassis by four M6 bolts, after being convenient for
The maintenance and maintenance of phase.
Fig. 3 and Fig. 4 illustrates the working principle of pantograph auxiliary rising bow jacking mechanism, when pantograph, which drops, bends, by electricity
Under the conditions of bow self weight, push pipe applies downward active force to supporting block until pantograph is fully located at chopper bar position state on upper frame
When (upper push pipe be placed in rubber buffer backstop), tray interior compressed spring stops compression, and supporting block is at this time to upper push pipe one
The maximum reaction force directly to keep up.When pantograph rising bow, under the synergy of normal rising bow driving force, bow body starts
It progressively disengages rubber buffer backstop and starts rising bow, until support is jacked up across upward to maximum limit height, upper push pipe is detached from support
Block, pantograph complete rising bow under the action of normal rising bow driving force.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
