Description

The invention relates to a device for the capture and unloading of roundwood from the water and can be used in the points of the melt. five

A device is known for unloading floating beams of timber, containing a base moving along a track, to which rods are pivotally attached with an emphasis u [1].

A disadvantage of the known device is the occurrence on curvilinear areas of great effort, leading to rapid wear of the rollers. 15

The purpose of the invention is to improve the conditions around the curvilinear sections of the track.

The goal is achieved by the fact that in the proposed device the base is made in the form of articulated beams with grooves filled with a material with a friction coefficient T = 0.050.2, and supporting skis attached to it. 25

In addition, in order to ensure sustainable movement along the track at idle, supporting skis are hinged

telescopic spring-loaded rods.

FIG. 1 shows a device for unloading floating bundles of timber, side view; in FIG. 2 is a cross section of an articulated beam-slider device; in fig. 3 is a flow chart of the operation of the proposed device for unloading floating bundles of timber, general view; figure 4 is the same, side view; in fig. 5 - the same cross section.

The device consists of several articulated slider beams 1, an emphasis 2 with articulated rods 3 and a flexible coupling 4, for example, a cable or chain, lateral supporting skis 5, articulated telescopic spring-loaded rods 6 and a groove 7 filled with material friction coefficient ί = 0.05-0.2, for example, plastic, wood, etc.

Unloading floating bundles of timber is as follows.

To unload beam 8, two single-loop devices 9 are required, which

installed on two parallel rail tracks 10, laid on the sleepers 11 and spaced from each other at an appropriate distance. The devices are moved on rails using winches and a cable block system. To receive the beam, the devices on the rails are lowered into (water under the timber bundle. With the passage of the devices under the ski bundle 5, due to the presence of buoyancy, they lift and touch the lower part of the beam. After leaving the beam, the stops 2 carry the rods 3 until will not touch the bottom of the beam.

When the device moves towards the shore, the stops 2 capture the beam. The beam rests on slider beams 1, and the stops 2 keep from tilting by flexible connections 4.

The captured bundle of timber is unloaded from the water to the place of processing.

From tipping over the rails, when the device is idle, the device is supported by skis5 connected with slider beams 1 through articulated telescopic and spring-loaded rods 6.

When the device is moving with a bundle of timber, the load on the supporting skis 5 is removed, since the receiving platforms of the slider beams by ensuring the ratio of their width to the height Ug 3 and the action of forces

gravity beam take horizontal flooring.

When introducing the proposed system, the issue of unloading the whips from the water with whole bunches is solved, since in the case of unloading with bunches, bypassing the grinding, the whipwigs are completely eliminated, the litter of the reservoir is eliminated by sludge, mud and dirt, and the conditions for breeding and preserving fish heads are improved.

Compared with similar devices, specific metal consumption is reduced by about five times.

The use of the proposed device makes it possible to increase the productivity of workers' work on unloading timber from water by 2-2.5 times.

Claims (2)

Claim 1. A device for unloading bundles of timber, containing a base moving along a track, to which rods are pivotally attached with a stop, distinguishes it with the fact that, in order to improve the conditions for bending around curvilinear sections of rail tracks, the base 25 is made in the form of articulated beams with grooves filled with material with a friction coefficient (–0.05–0.2, and supporting skis attached to it. 2. Device by π. 1, due to the fact that, in order to ensure stable movement along the track at idle, the supporting skis are suspended on articulated telescopic under 35 spring-loaded rods.
