Abstract

The invention can be used in the installation of metal greenhouses. The purpose of the invention is to reduce manual labor in transferring the lift from the transport position to the working position and vice versa. The mobile hoist contains the main 1 and additional 2 platforms, a cable-block drive, the ropes of which are fixed on racks, stocked through blocks connected to the rod, and fixed on tension devices of additional platforms. Additional pads 2 are connected by a plate in which there is a guide hole for the rod, on which the limiting stop rests. A spacer is installed on the frame for supporting the rod. 1 hp f-ly, 7 ill.

Description

The invention of OVHOCHTCH to the field of mechanization of the installation of metal structures of greenhouses by machines having working platforms is an improvement of the invention according to the authors. St. No. 1370065.

The purpose of the invention is to reduce manual labor in transferring the lift from the transport position to the working position and vice versa.

Fig about 1 shows a mobile lift in the working position; in fig. 2 - the same, in the transport position; in fig. 3 is a diagram of a rope block device and stops with elastic elements at the working position of additional platforms; in fig. 4 - the same, in the transport position; in fig. 5 - the same, when translating additional sites into position; in fig. 6 — node I in FIG. one; in fig. 7 - node II in FIG. 2

The rope-block for transferring the main I and an additional 2 sites from the transport position to the working one and vice versa contains a vertical rod 3, in the upper part of which there is a system of blocks 4 fixed with the help of an adjusting screw 5.

The rod 3 is provided with a limiter-Hbw stop 6, which prevents the connecting plate 7 from moving upwards, connecting the additional platforms 2 and sliding along the rod 3.

Ropes 8 pass through the system of blocks 4, each of which is fixed at one end to the upper end of one rack 9 and the other to an additional platform 2 fixed to the other rack.

The block system consists of the body 10 and the tongs 11, which are connected by plates 12, on axis 13 rotates blocks 4, on which the ropes 8 cross each other. In the lower part of the body 10 there is a threaded hole 14 for connecting the body 10 to the vertical rod 3. - screw screw 5, on which there are lock nuts 15.,

 The tensioning device, fixed at the ends of the additional pads 2, consists of a screw 16 rotating in sliding pins 17, has a nut 18, to which is attached

rope 8 in the clamp 19, the end of the screw 16 is made turnkey 20.

The stops 21 are hinged on; racks 9 with the possibility of rotation in the horizontal plane. The elastic elements 22 connect the additional pads 2 to the stops 21. The device is provided with a support spacer 23 for fixing the rod 3 over the frame 24.

The mobile hoist is operated as follows.

The elevator is installed in the span of the block of greenhouses, after which the pivoting stops 21 are installed in the position indicated in FIG. 5, and, acting through the elastic elements 22, erected t additional platforms 2 from the vertical position,

The lifting mechanism of the transport trolley, for example, including a hydraulic lift and a sliding frame such as Nuremberg scissors, is used to lift the main 1 and additional platforms 2. The latter, fitted with elastic elements 22 and 3 of the vertical position, take a horizontal position at which the connecting plate 7, connecting additional pads 2, and sliding along the rod 3, reaches the limiting stop 6. A further rise is carried out simultaneously by the entire block device, through the ropes 8 which horn retained

additional pads 2 in a horizontal position.

 At the required height required by the technological process, the clamps connecting the main I and the additional 2 platforms are disconnected and a further rise occurs only at the main platform. The additional pads 2 are held in a horizontal position by the ropes 8 through the blocks 4 located on the axis 13, which is held by the plates 12.

The non-horizontality of the additional pads 2 is eliminated by an adjusting screw 5 connecting the system of blocks 4 with the rod 3. To do this, unscrew the lock nuts with a 15 turn of the screw 5 to eliminate the horizontal position of the additional pads 2, then turn the lock nuts 15.

When one of the additional sites takes a non-horizontal position, this is eliminated.
