SU509523A1 - A device for opening and closing a swivel hatch cover in places where a load rope is attached to a craneso boom - Google Patents

Description

The invention relates to field transport vehicles.

Known ycTtjoiir-; in order to open and close the liOBOpoTHon hatch cover at the points of passage of the load rope on the crane with the boom fixed on the axle, containing a slider that is not stirred at the hatch fixed on the hatch cover.

However, in the known device the cargo rope, due to the constant T15

hatch cover elements are severely deteriorated.

The purpose of the invention is to ensure the reliability of the device.

This is achieved by mounting a copier on the boom attachment axis, which is connected by a lever-cable system with a slider.

The proposed device schematic JCKH shown in the drawing.

The device includes a cover 1 fixed with the help of the hinge 2 on the casing 3, a rotary strut 4, a cable 5, a spring-loaded cable 6 installed with the help of the hinge 7 on the turntable 8 and a copier 9 fixed on the root part of the boom 10.

In order to reduce the friction between the cam 9 and the hatch b, the roller 15 is mounted on the latter, and in order for the lid 1 to open or lock the lid 1 to correspond to the position of the boom 10 (working or traveling position), the lever 6 is fitted with a spring 16, the second end of which is fixed to the swivel The arc form B, Copier 9 is a disk with a depression 17 and a protrusion 18.

The copier 9 and the boom 1O have one axis of rotation 19. The hoisting rope 2O is laid on the drum of the winch 21 directly from block 22 on the boom tip 10, the width of the lid 1 is selected; depending on the length of the drum winch 21.

In structures of nettles in which lid 1 must open to a vertical position - n more relative to the ground, a hinge spring must be placed in hinge 2 to ensure that lid 1 closes. When the lid 1 is tilted, the lid closes by its own weight. .

In the stowed position of the crane, the boom 1O is in the folded state (position 1), in this case the roller 15 is in the depression 17 of the copier 9, and the lever 6, the cover 1 and turn the brace 4 also occupy the position I.

When translating the boom 10 into position II, the copier 9, turning, presses its protrusion 18 through the roller 15 onto the lever 6, which moves to the position M and t does not take the cable 5. The second cable 5p (turns around the hinge 11 the brace 4, stir the slider 12 along the guide 13 and open the lid 1, which turns around the hinge 2. In this case, the strut 4 and the lid 1 also move to position II.

At the position 11, the GradePoop contact 2O can freely mix without any contact with the elements of the casing 3 or the cover 1.

When translating the boom 10 from the working position II to the traveling position I 6 under the action of the spring 16 and moving the roller 15 back to the cavity 17, Koniqja 9 occupies Position G. At the same time, the Loose cable 5 does not hold the brace 4 in position 11, the cover 1 under its own the weight turns around the hinge 2 and closes,
