Description

DETAILED DESCRIPTION OF THE INVENTION The present invention generally relates to an elongate load engaging body which travels on channel tracks and which can be raised and lowered with respect to at least one bogie body via tilting block and roller means when moving in a relative longitudinal direction. This relates to a type of cargo handling trolley consisting of:

A known example of such an in-track trolley device is the registered trademark “
There is one marketed by the applicant by JOLODA J.

A fairly solid flat floor on which the track rests, and a fairly rigid load such as a container or pallet, allows a small lift height to provide rear balance for the trolley to run freely for the load above the floor after insertion and lift. Suitable for guiding trolleys of significantly lower appearance into sufficiently shallow orbits.

Regarding floors of poor strength and flatness and unsolid loads,
Directed by installing minimal cost floors, pallets and containers. The tendency is for the bending or deflection to produce a sufficient height of rise that is always sufficient to avoid load-to-floor contact during movement of the load by the trolley.

The object of the invention is to provide l-lorries with a higher lifting height and a higher appearance of the trolley in their non-lifting state without requiring deeper tracks.

The fame of the Jorda trolley lies especially in the close inter-engagement of the hanging walls of the load-engaging body with the reverse channel cross-section and the side walls of the bogie body (essentially), the flat bottom of such walls in the non-raised state of the trolley They are based on a robust and well-engineered construction with positive retention mechanisms between the side walls and the hanging walls. Although Applicant further attempts to retain these features, the limitations set by rigid pins and protrusions and groove or slot type positive retention mechanisms prevent achieving the desired amount of increased life. There is.

Accordingly, the applicant has proposed a locking component, namely a locking part, and at least one member connected to the locking part and coupled to the trolley part for movement during relative movement of the locking body and the bogie body. A positive retention mechanism is proposed which is essentially characterized by including an arrangement with two other relatively movable components, i.e. movable parts.

With respect to trolley sections of the same foundation (the inclined blocks are closer to each other due to the correct lateral position of the sides of the bogie body being overlapped by the hanging walls of the load engaging body which are preferably close together over their entire length, the trolley The total lift height should approximate the available height of the space within the reverse channel type load engagement surrounding the bogie, although it is preferred that the total lift height be slightly less than . , preferably with a positioning recess at the highest point of the inclined block, which is larger on approach.

A particularly robust embodiment is a spring link in which the rollers engage with the rollers surrounding the shaft or rod or other lateral connections of the bogie body in slots in the links which are clamped by cooperating wedges and which provide an effective guiding and retaining engagement. It has a holding mechanism in the form of.

The basic operation of the preferred embodiment of the invention is that the internal fillers on the sides of the bogie body work equally well, but the springs for the roller axles or connecting rods when the rollers ride on the tilting blocks of the load engagement body. This is the bending of the deterrent body. The use of a roller axle is because the internal protrusion from the bogie sidewall is usually closest to the slope and is most effective for at least the material, especially when the rollers of the bogie body are not to be displaced, more than for other design reasons. Command from the end of the bogie body associated with the end.

The l-lorry according to the present invention can necessarily be subjected to extremely rough handling, being dropped if not thrown onto a concrete floor, and the trolley can easily withstand such handling without failure and damage. can.

In the present invention, for such handling, the spring link in guiding relation of the roller axle is fully (if dependent) extended beyond the side wall of the load engaging body with a detrimental effect, and then the bogie body is moved to its corresponding position. It is preferable to protect against the possibility of being displaced and ejected from the spring. Suitable latching, the primary action of which is easily provided by spring means, is carried out by means of a flared leg of a generally mouth-shaped wire member having a curved portion which is secured to the underside of the sloped block of the load engaging body. It can be stretched.

Suitable spring links may be formed to engage adjacent to each side of the bogie side walls by a one-piece structure of spring steel, or other suitable material may be provided to be fastened to the underside of the ramp block of the bogie body. formed of a sheet material having a first portion, or locking portion, and a portion, or movable portion, extending on each side of the inclined block, the extensions or movable portions being connected to the first portion, or movable portion; It is folded back at a suitable distance from the locking part, and preferably after a distance corresponding to the maximum displacement of the roller axis, and in the raising of the tilting block, more preferably in that case a slot corresponding to said maximum displacement is formed. and is further preferably folded back through such first fold bend I7 to form a first fold bend, and then preferably folded back along the first-mentioned extension. A very convenient method which has been found to be sufficient to achieve a spring link is to form a spring link in the center so that its flat ends can be formed in overlap with the bends made in both interconnecting side parts. It may consist of a plate or sheet of spring material with openings in it.

Preferred embodiments of the invention will now be described in detail with reference to the accompanying drawings.

In the figure, the detailed trolley 10 carries a load engaging body 12 of channel-shaped cross section with its web 14 pointing upwardly for engaging the load and its side walls 16.degree. 18 depending downwardly. A bogie car body 20 is disposed in the adjacent gap between the side walls 1B and 18, and the bogie car body 20 has embedded bolts 2.
6, a roller shaft 28 and a bearing rod 30 for an articulating link 32 between the bogie bodies, which bearing rod 30 is connected to the load engaging body, i.e. with the trademark "Waterpool". There are usually at least two per trolley or trolley telescoping unit commercially available on the basis of YOLoDA.

Of course, the rollers 34 on the shaft 28 are always connected to the bogie sidewall 22

2 is an inclined block 4 fixed to the underside of the web 14.
0 and has one suitable raised surface 42 for the rollers 34, although this inclined block 40 is actually shown as having two sides. This surface 42 leads via a side or edge 44 into a roller positioning recess 46 for the raised position of the trolley 10. 1. Mouth! Changing between states of J-10 requires relative longitudinal movement of its load engaging body 12 and bogie body 2o, and in practice moves the bogie body 20 of FIGS. 1-3 from left to right. It is necessary to move and stir.

The bogie car body 2o also has rollers 48 for moving the trolley 10 along a track (not shown), and the rollers 48 either rise to protrude from the track to load cargo or descend to the track mouth. and unload the cargo.

It is clear from FIG. 3 that in the raised position of the 1-rolly there is a slight overlap between the side walls 16.18 and 22.degree. 24. Furthermore, as the roller 34 passes over the side or edge 44, there is a small overlap of about 3 mm prior to its raised position.

The retaining linkage for the trolley bogie and load engaging body is designated 50 and is shown in detail in FIGS. 4-6. The spring linkage 50 extends from the connecting plate 56 which is open at 58.60 for fastening to the underside of the ramp 40 through bolt holes 60.60 and has two regularly spaced parallel links which are folded back into the connecting plates 56. It has elastic arms 52,54. Insert the arm 52 so that the roller shaft 28 is tightly housed in the spring link mechanism 50.
