Description

This invention relates to a monorail transport, namely to cargo trolleys of overhead monorail roads.

The purpose of the invention is to simplify the design.

FIG. 1 shows a load trolley of an overhead monorail with an oriented position of the load in the transport position; figure 2 - section aa in figure 1; on fig.Z - truck trolley in the original (on load) position; figure 4 - view B in fig.Z; in FIG. 3, view B in FIG. 3; figure 6 - node I in fig.Z; figure 7 - node II aa figure 2; on Fig - section GG in figure 4; figure 9 - section dD in fig.Z; figure 10 is an arbitrary position of the cargo when lifting; figure 11 - the position of the cargo at the time of capture of the gear when rotating the latter.

The trolley of the overhead monorail contains a carriage 1 moving along the monorail, connected by a frame 2 with vertical guides 3. On the frame 2 a load lifting mechanism 4 is installed, on the hook 5 of which a catch 6 attached with a conical hollow nozzle 7 for centering the load two diametrically located pins 8 with rollers 9 (Fig. 6). Along the guides 3, the slider 10 freely moves with the gear wheel 11, which relative to the center of the slider 10 can freely rotate on the ball bearing 12 (Fig. 8). The gear wheel 11 has two diametrically opposite grooves 13 at the end (FIGS. 4-7), in which, when rotated, slits 8 with rollers 9 are sunk. Gear wheel 11 is driven by gear 4 from gear rack 15 attached to the guide through conical a pair of 16 and a gear 17, which engages with the gear wheel 11 (Fig. 4). The shaft bearings of the pinion 14, the conic pair 16 and the gear 17 are on the slider 10. The stroke of the slider 10 from the lower stop 18 to the upper stop 19 is chosen so that it is equal to 180 ° rotation of the gear wheel 11 (half a turn). The path of the trolley to move over the aisles, passages and workplaces according to the requirements of safety engineering is protected by a stationary fence 20.

Cargo trolley works as follows.

In the initial position (FIG. 3), the load 21 is on the floor and the grip b fixes it. After the load lifting mechanism 4 is turned on, the latter begins to rise. Since the hook 5 relative to the hook clip rotates freely, and the load 21

unbalanced, then when lifting there are forces turning the load in the plan. In addition, when winding the rope (one) onto the drum of the lifting mechanism (the second rope is fixed on the body of the lifting mechanism), the hook of the yoke turns, and consequently, the load tends to turn. As a result, the load, when lifted to the upper position, occupies the position (in plan) shown in FIG. ten.

When the load 21 approaches the slider 10 (the latter is in the lower position and is held by the stops 18), the conical nozzle 7 of the gripper 6 enters the conical opening of the gear wheel 11. Since the grooves 13 of the gear wheel 11 are oriented strictly relative to the axis of the monorail (in the initial period), and the load 2 is in an unoriented position (FIG. 10), then the rollers 9 of the crankshaft 8 do not fall into the grooves 13 of the gear wheel 11. Since the lifting of the load 2

0 with the gripper 6 continues, the latter through the pins 8, the rollers 9 raise the slider 10 together with the gear wheel 11. At the same time, the brush 14 rises, which runs around the rail 15 and causes the conical pair 16 to rotate, and through it

5 is a gear 17 which causes the gear 11 to rotate.

When the gear wheel 11 is rotated in a certain area, the rollers 9 of the hooks 8 coincide with the grooves 13. The gear wheel 11 joins the gripper 6, and the latter also begins to turn. When the slide 10 approaches the anvil 19, it stops lifting, and also the rotation of the gear wheel 11 (it makes a turn of 180 °), while the load 21 becomes the oriented long side along the monorail.
