Description

Electric hoist cable protection mechanism with small cable offset abrasion

Technical Field

The invention relates to the field of hoisting equipment, in particular to a cable protection mechanism of an electric hoist with small cable offset abrasion.

Background

Electric block is a hoisting equipment commonly used, and electric block has characteristics such as small, and the dead weight is light, easy operation, convenient to use for industrial and mining enterprises, storage, places such as pier, when electric block uses, uses the rope winding ware usually to the even winding of cable of guaranteeing to withdraw is on receiving the line roller, and sets up stop gear on the rope winding ware and carry on spacingly to the cable, ensures that the rolling direction of cable keeps unanimous.

However, when the existing electric hoist is used, the hoisted object is easily influenced by factors such as external wind power and the like to swing, at the moment, the cable swings along with the cable, transverse partial friction is easily generated between the cable and a limiting mechanism of the rope guider, the cable is easily abraded seriously after long-time use, the swinging of the cable is not buffered, the safety of the hoisted object process is influenced, and the energy consumption of the hoisting equipment is increased due to the increased centrifugal force when the hoisted object swings.

Disclosure of Invention

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a cable protection mechanism for an electric hoist with small cable offset wear comprises a positioning sleeve 1, wherein the positioning sleeve 1 is fixedly installed at a cable outlet at the bottom of a rope guider 2 of the electric hoist on the electric hoist, and keeps the positioning sleeve 1 in a horizontal state, i.e. when the electric hoist works, the positioning sleeve 1 keeps in the horizontal state, a notch is formed in the top of the positioning sleeve 1 for a cable to pass through, eight connectors 3 are fixedly connected to the top of an inner cavity of the positioning sleeve 1, the 8 connectors 3 are circularly distributed on the top of the inner cavity of the positioning sleeve 1, a limiting sleeve 4 positioned in the inner cavity of the positioning sleeve 1 is fixedly connected to the top of the eight connectors 3, a through groove is formed in the middle of the limiting sleeve 4, the inner diameter of the through groove is uniformly increased from top to bottom, two cable jackets 5 are movably sleeved in the through groove of the limiting sleeve 4, and the outer sides of the two cable jackets 5 are, the cable passes through the two cable jackets 5, when the cable jackets 5 are not deviated and kept in a vertical state, the two limiting sleeves 4 move upwards relative to the cable jackets 5 so as to be separated and loosen the cable, so that the cable can be paid off and wound, when the cable swings under the influence of a suspension object, referring to figure 1, for example, the cable swings leftwards so that the two cable jackets 5 swing leftwards and the limiting sleeve 4 moves downwards relative to the cable jackets 5, so that after the cable is clamped by the two cable jackets 5, the left side of the limiting sleeve 4 is in contact friction with the inner wall of the positioning sleeve 1, the transverse friction between the limiting sleeve 4 and the outlet at the bottom of the positioning sleeve 1 is avoided, the abrasion degree of the cable is effectively reduced, the service life of the cable is prolonged, the connector 3 far away from the side of the limiting sleeve 4 deviated is in a stretching state, the swinging of the limiting sleeves 4 is effectively buffered, and the swinging amplitude of the limiting sleeves 4 is reduced, and then reduced the swing of cable, be favorable to the suspended object of cable bottom to tend to stable, guarantee cable safety and stability's promotion suspended object, avoided extra useless power consumption.

Wherein, the outer edge of the top of the cable jacket 5 is fixedly sleeved with an annular upper magnetic block 501, the top of the position-limiting sleeve 4 is fixedly sleeved with a lower magnetic block 401 positioned below the upper magnetic block 501, the top of the lower magnetic block 401 and the bottom magnetic pole of the upper magnetic block 501 are the same, the repulsive force of the lower magnetic block 401 to 402 is utilized to enable the cable jacket 5 to overcome the gravity and be hung in a through groove in the middle of the position-limiting sleeve 4, and the two cable jackets 5 have slight extrusion force to the cable in the middle, when the cable moves up and down for lifting, the friction force to the cable is small, and simultaneously when the cable shakes, the cable jacket 5 and the position-limiting sleeve 4 immediately act, thereby reducing the friction between the cable and the outlet part at the bottom of the positioning sleeve 1 when the cable shakes, further improving the service life of the cable, and the use of eight connectors 3 enables the cable to have a, further improving the effect of buffering the swing of the cable.

Wherein, the cable wire casing has been seted up at the middle part that the cable pressed from both sides the cover 5 to the cable passes, and is equipped with the ball 502 that is located wire casing both sides notch department on the cable wire casing 5, and ball 502 from top to bottom equidistance distributes in the cable wire casing, makes two cable press from both sides the cover 5 and carry the cable, and the rolling friction of ball 502 and cable replaces sliding friction, has reduced the friction loss of cable, makes the life of cable improve.

Wherein, the bottom export of position sleeve 1 is loudspeaker formula design, avoids the cable oscillating and position sleeve 1's bottom export position contact friction, and the inclined plane department of 1 inner chamber bottom of position sleeve is fixed with the dog that the round is located stop collar 4 department, and the hardness of dog is less than stop collar 4's hardness, rubs through dog and stop collar 4, protects the inner wall of position sleeve 1 to change when the dog degree of wear is great, need not to dismantle other parts.

When the device is used, the positioning sleeve 1 of the protection mechanism is fixed to the rope arranging outlet of the electric hoist rope arranging device 2, the cable is limited, when the cable swings under the influence of a lifted object, the cable clamping sleeve 5 is driven to move towards one side, the limiting sleeve 4 moves downwards relative to the cable clamping sleeve 5, the two cable clamping sleeves 5 clamp the cable, the limiting sleeve 4 and the cable clamping sleeve 5 swing along with the cable, the outer side of the limiting sleeve is in contact friction with the inner wall of the limiting sleeve 1, meanwhile, when the limiting sleeve 4 moves towards one side, the elastic connecting rope 3 far away from the moving direction is in a stretching state, the limiting sleeve is pulled back, the swinging amplitude of the limiting sleeve is effectively buffered, the buffering amplitude of a heavy object and the cable is further reduced, and the cable can be safely lifted.
