Description

The invention relates to the area I of the mechanization of loading operations, the pre-I property of the automobile-furgo- f nah.s

The purpose of the invention is to ensure the reliability of work by ensuring the movement of the trolley without distortions and jamming.

Figure 1 shows a lifting device, general view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1; Fig, 4 - section bb In Fig, 2; on fig.Z - section GGD on fig „2; figure 6 - section D-D 15 figure 2; Fig. 7 is a diagram of the stroke and location of the load-lifting cables of the trolley shifting mechanism; Fig. 8 is a section E-E of Fig. 6 (construction of a driving drum); 20, FIG. 9 is a section through ZHZ in FIG. 6 (block set construction).

The lifting device comprises a trolley 1 with a gripper 2 mounted movably on rail beams 25 3 and 4 fixed on the base of side walls} 5 and 6 of the van 7 having a protrusion 8 above the cab 9 with an end wall 10.

The trolley 1 contains a frame 11, on which a lifting mechanism 2 is mounted 12 and a trolley 1 moving mechanism 13, equipped on both sides with four support rollers 14-17 (figure 4) for movement along rail-35 vm beams 3 and 4 .

The mechanism 13 for moving the carriage 1 (Figures 2, 4, 5, and 6) contains an electric motor 18, a gearbox 19, on the low-speed shaft 20 of which a drive train is attached to a multi-drum 21, driving the rope drive containing two drive cables 22 and 23 ( 2, 5, 6, 7), envelopes one above and another below the driving drum 21, 45 blocks 24 and 25 and blocks 26 and 27, mounted on frame 11 of body 1, and further additional (rotary) blocks 28 - 31 mounted on the end wall 10 of the protrusion 8 and the upper door 50 with an opening 32 and secured by all four-f ends to the tensioning device tvam 33-36. The blocks 24 and 25 (Fig. 9) consist of a set of separate blocks 37-39 movably mounted on the common axis 40 of the trolley 1.

The lifting device operates as follows.

The lifting mechanisms 12 of the gripper 2 and the movement 13 of the trolley 1 provide the possibility of mechanized loading, unloading and moving goods at the loading platform and inside the van.

When the movement mechanism 13 is turned on, the plane-parallel translational-return movement of the trolley 1 with the exit grip 2 outside the van 7 through the doorway 32 to perform loading operations is provided.

When the lift mechanism 12 is turned on, the possibility of slinging, lifting and lowering the load is provided. Multi-wheel drive drum 21 in cooperation with blocks 24 and 25 provides reliable, without slippage, movement and fixation in the transport position of the drive carriage
