Description

It is also attached to the water, it is attached to it // in which it is placed on the load to press the lower end of the rod to the bottom of the river or canal. In addition, on the part of the rod, there are clamps Ю, into which, if necessary, an additional end 12 (Fig. 5) is inserted for sliding the rod 7.

The left shoulder of the lever / carries the adjustable counterweight in the form of a water filled crate .3 with a crane. In addition, a cable 24 is attached to the winch 15 via the chain hoist to the left end of the batcher /.

In addition, the lever is also connected by means of a cable 16. The driver through block / 7 on the crossbar 21 of the b-pillars, with the winch 18 at the rear end of the raft.

A further TIXK 25 is attached to the hook of the upper stanza 7, going through the hook 20 of the crossbar 9, mounted on the uprights 26.

The action of the lot is as follows.

If there is no need for a lot, and for a long time it will not be necessary to use it, then nz shchik 3 is released in

(edge) water, and the winch 18 is lifted by cable 16, which is connected through block 17, to the left end of the rod / so that its right end lowers along with axis 4 and the upper end of rod 7. In this case, the lower end of rod 7 rises and does not touch bottom. If the depth of the river is so small that in spite of raising the lower end - rod 7 it still touches the bottom, then with the help of the Lüders block suspended from the hook 20 of the crossbar I push the upper end of the beam 7 upwards. The lower end of it is also pulled up with the help of a levvd / and upwards, the pin of the Kotiett rod 7 to 11е1х; luggage 11e, and the lower end to njroTy, so that the ha of 7 remains suspended. Then water is released from the pin 3. Lower the left end of the horizontal lever / onto the bar 27 racks in (it is advisable to place a spring on this bar to soften the impact of the lever /) and thus give the lever / simultaneous support on the bar 27 and on axis 2.

First of all, it is necessary to pour water into box 3, which requires up to 1.5 sh water. Since it is necessary to fill up once only at the start of the lot, there is no need to make special devices for this, and you can make it manually with buckets (about 150-180 buckets).

Then, it is necessary to lower the pull rod 7 to the required depth. To do this, you first have to pull the cable from the raft to the lower end of the rod 7, which is produced by one person. At the same time, the end of the rod will be lowered to the bottom. Then, using the Lüders block suspended from the crossbar 9. Lower the upper end of the pole 7, which is lowered and lies on the axis 4. This can also be done by OAitHM man. Because of this, if the rafts move, the lot is already starting to work.

If the water load in box 3 is too large for this raft, and the raft stops, then through the tap part of the water is released from the raft and equalize the load with water so that only raft braking takes place.

If, on the contrary, the load of water in box 5 is insufficient, then the lot is strengthened with the help of a hand winch 15, acting on the left end of the lever / to push it downwards.

Due to the weight of water poured into box 3, as well as due to its own weight of the lever /, its left end tends to go down and it turns counterclockwise relative to axis 2. At the end of the lever / there is a force (vertically upward), part of which through the axis 4 transmits the upper end of the rod 7 resting on it.

Gyluch Mye BCpxinnt with the end of the Rod 7 force, 1:; the length of the rod is p11 to the length, so it turns out at the lower end of the bar the force (lapse) that acts (dapit) on the river. The sum of the forces at the upper and lower ends of the P1thang1g 7 is transmitted to a horizontal axis 5 firmly attached to the two end rear logs of the raft.

As a result, the forces acting on the horizontal axis 8, depending

fvri

If it is required to work at depths of more than 4 m, then it is necessary to lower the end of the rod 7 and insert auxiliary bars 12 into the collars 10, which, of course, can only do lower end of the rod 7 to the water level.

In view of the great friction that arises from the action of the rod 7 on the bottom, its lower end can be sheathed with sheet iron and can be made as large as possible by the area of contact with the bottom.

The subject matter of the invention.

Claims (3)

1, Lot for controlling, for example, rafts, made in the form of a lowering rod, characterized in that, in order to regulate the pressure of the lower end of the rod 7 .to the bottom, while maintaining the possibility of automatic 4 Its lifting and lowering in the MocTii depended on the bottom relief, it was installed swinging around support 8 and its upper arm was influenced by beam 4 of the loaded lever /, and the lower arm was mounted Y /, loaded onto the raft as needed. 2. The form of the lot according to claim 1, from scoring with the fact that for a variable load of the lever / on its shoulder opposite to the supporting bar 4. a longitudinally adjustable and filled box 3 is suspended, a cable 14 is attached to the end of the shoulder hand winches 15. 3. In the lot according to claim 1, use for loading chic // metal chains lowered into the box for the length necessary to create the required load.  FIP5 If
