Description

SPECIFICATION Mechanical handling apparatus The invention relates to mechanical handling apparatus.
According to the invention there is provided mechanical handling apparatus including a surface and power means for moving a load over the surface which comprises a substantially vertically reciprocable platform device for actuating the load, and a lever device including at least two oppositely pivoted levers for raising and lowering the platform device.
According to the invention, there is also provided apparatus for mechanical handling of loads, comprising a platform for carrying loads, means for raising and lowering the platform, said means including at least two levers each pivoted relative to the platform and each pivoted relative to a respective one of a pair of actuating members, the actuating members being movable towards and away from each other whereby relative movement of the actuating members in one direction pivots the levers to raise the platform and relative movement of the actuating members in the opposite direction pivots the levers to lower the platform.
Mechanical handling apparatus embodying the invention is hereinafter described, by way of example, with reference to the accompanying drawings.
Figure 1 is a longitudinal sectional view of part of the apparatus in one position; Figure 2 is a view of the apparatus of Fig. 1 in an alternative position; and Figures 3 and 4 show, to a smaller scale than Figs. 1 and 2, respective operating schemes for those two Figs.
Referring to the drawings, there is shown mechanical handling apparatus 1 including a surface 2 and power means 3 for moving a load over the surface 2, which means comprises a substantially vertically reciprocable platform 4 for contacting the load, and a lever device 5 including at least two oppositely pivoted levers 6 and 7 for raising and lowering the platform.
The apparatus 1 may be installed in a container vehicle in which a load is passed along the length thereof on rotatable means such as rollers which are set in the floor of the vehicle in two substantially parallel tracks. Preferably the rollers are raised and lowered with respect to the floor of the vehicle by means such as apneumatically inflatable air bag extending the length of each track. When this back is inflated the rollers stand proud of the floor and the track is "live". When deflated, the rollers sink below the level of the floor, and the track is dead.
The power means 3 comprises an elongate member such as a chain 8 trained round two opposite sprockets 9 and 10 mounted on horizontal axles, the ends of the chain 8 being connected to a roller cradle which comprises two inverted channels 11 and 12 in use each with rollers 13 protruding through the respective open bottoms to roll on a sub-floor or the like of the vehicle. The two channels 11 and 12 are connected by a rod 14 which supports in each channel resilient means such as a spring 15 held between an end wall 16 of the channel and a captive abutment such as a nut 17 on the rod 14. The top of each channel 11 and 12 has a series of slots 18 through which project parallel levers 6, 6' etc., and 7, 7' etc., which are pivoted at one end between opposite side walls of the respective channel and the platform 4.The levers 6, 6' of the channel 11 pivot in the opposite sense to those of the channel 12.
The sprocket 9 is movable in the direction of the arrow "A" in Fig. 3. The sprocket 10 is driven.
In use, for the platform 4 to contact a load, it is necessary for the sprocket 9 to be moved in the direction of arrow 'A' (Fig. 3) so pulling the channel 11 to the left and the channel 12 to the right as viewed because the effective lengthening of the chain 8 is accommodated by the right movement of the channel 12 as the sprocket 10 is fixed. This movement of both channels 11 and 12 is also accommodated by the levers 6, 6', 7, 7' etc., pivoting in unison in opposite senses in the two channels, to raise the platform 4 equally, to the load engaging position. If the power means driving sprocket 10 is now actuated, the chain 8 draws the platform 4 along the vehicle floor as desired. To disengage the platform 7 from the load, it is merely necessary to return sprocket 9 from the Fig. 3 position to the Fig. 4 position.This effectively "shortens" the chain 8 and the stored energy of the springs 15 return the channels 11 and 12 together, as shown in Fig. 1.
