A kind of open conveying strip
Technical field
The utility model relates to a kind of basic building block of light-duty gravity type boat davit roller conveyor.
Background technology
Existing advanced conveying strip, its long trough shell frame biside plate upper end is extended with the relative square bracket shape groove of notch, running roller is uniform to be arranged in the elongated slot, its rolling axle two ends directly are held under the two square bracket shape grooves on the trough rim plane, and are positioned to be inserted in the breach slotted eye of offering the positioning strip lower end in the two square bracket shape grooves.The advantage of this conveying strip is that assembling is easy for installation, and the running roller location accurately.And the shortcoming that exists is when being the running roller running, and its two ends are bigger to the wearing and tearing of shell frame trough; In addition, long trough shell frame is to rely on the groove or the screw hole of its bottom surface to install and fix, and is not very steady leaning on during load operation.
Summary of the invention
The purpose of this utility model, be that above-mentioned conveying strip is carried out technological improvement, not only assemble easy for installationly that running roller location accurately thereby provide a kind of, and the rolling axle running shell frame trough that do not wear and tear, make long trough shell frame that very firm novel open type conveying strip is installed simultaneously.
The technical scheme that realizes above-mentioned purpose is: it comprises the long trough shell frame that is provided with a pair of positioning strip mounting groove, the uniform running roller that is arranged in the shell frame elongated slot, it is characterized in that having two can insert the rolling axle installing and locating bar in a pair of positioning strip mounting groove on the shell frame, the uniform bearing hole that can hold the rolling axle axle head that offers on its elongate body respectively.
Rolling axle of the present utility model is installed in the bearing hole of positioning strip, and running is lubricated, and noise is little; It not with the shell frame trough direct contact, Gu and the shell frame trough that can not wear and tear has improved the conveying strip whole service life greatly; Conveying strip shell frame bilateral fixed installation simultaneously, very steady reliable.

The specific embodiment
Preferred embodiment, long trough shell frame 1 adopts aluminum alloy to draw and forms, and the relative square bracket shape positioning strip mounting groove 5 of notch is extended in its biside plate upper end, and the biside plate bottom is the outside rail mounted mounting groove 4 of notch; Rolling axle installing and locating bar 6 adopts engineering plastics to make, the uniform bearing hole 8 that can hold running roller center shaft 9 axle heads that offers on its elongate body, and for economical with materials, the uniform material-saving hole 7 that offers on positioning strip also; Center shaft 9 two ends of running roller 2 are inserted in the bearing hole 8 of two relative positioning strips 6, insert abreast then in the shell frame mounting groove 5, two end cap upper cover 3 promptly constitutes the utility model conveying strip.
