Abstract
The utility model relates to a friction increasing liner for a friction lifter, which comprises a supercharging capsule with a U-shaped cavity body. The supercharging capsule is arranged in a groove of a roller case body of the friction lifer. The bottom of the cavity body is provided with a spring and a shim plate. A radial liner in the shape of a triangle is arranged in the U-shaped groove. Both sides of the utility model are provided with a lateral liner. The supercharging capsule and the lateral liners are clamped in the roller case body by a cover plate which is arranged on the roller case body. The utility model has the advantages of simple structure, and convenient installation, and can enhance the lifting capacity of the lifter in multiples.
Description
The utility model relates to a kind of liner of friction drive hoist, a kind of liner that improves friction drive hoist roll friction power of more specifically saying so.
In order to improve the hoisting capacity of friction drive hoist, consistent way is both at home and abroad: the gasket material of development great friction coefficient, and do not study from the structure of liner, the cost of this gasket material is extremely expensive, and the friction coefficient that improves is also limited.Generally make liner in order to polyurethane, polyvinylchloride or multiple composite material both at home and abroad, its friction coefficient is near 0.25.
The purpose of this utility model is to have designed a kind of friction drive hoist simple in structure, easy for installation, that cost is low, friction coefficient is multiplied in order to overcome above-mentioned the deficiencies in the prior art part to increase the liner that rubs.
The purpose of this utility model can realize in the following manner: a kind of friction drive hoist increases the liner that rubs, include the supercharging capsule that cavity is the U type, it is placed in the groove of friction drive hoist drum housing, the U die cavity perfusion in vivo liquid of supercharging capsule, cavity bottom is provided with spring, be mounted with the radially liner of triangle in the supercharging capsule U type groove, its both sides have the side direction liner of inverted triangle shape respectively, and cover plate is stuck in supercharging capsule and side direction liner in the groove of drum housing.
The utility model compared with prior art has following advantage: 1. utilize the hydrostatic pressure principle, steel rope is subjected to from the positive pressure of liner and two side direction liners radially, thereby improve the friction force between steel rope and liner greatly; Thereby improve the hoisting capacity of friction drive hoist.2. under the situation that does not change existing friction drive hoist structure, this liner can be installed.3. this gasket construction is simple, and is easy for installation, and cost is low, but can significantly improve the hoisting capacity of friction drive hoist.
Description of drawings:
Accompanying drawing is a structural front view of the present utility model.
The utility model is described in further detail with reference to the accompanying drawings:
Shown in accompanying drawing: a kind of friction drive hoist increases the liner that rubs, include the supercharging capsule 4 that cavity is the U type, it is placed in the friction lining groove of friction drive hoist drum housing 3, supercharging capsule 4 usefulness rubber are made, its U die cavity perfusion in vivo liquid, the bottom of U die cavity body is provided with spring 6, it selects laminated spring 6 for use, on the spring 6, following two ends are provided with backing plate 7, to prevent that spring 6 from directly contacting with supercharging capsule 4, damage supercharging capsule 4, be mounted with the radially liner 5 of triangle in the U type groove of supercharging capsule 4, its two base angle is identical, and the best is 50 °～70 °, in the both sides of liner 2 radially the side direction liner 2 of inverted triangle shape is arranged respectively, cover plate 1 is stuck in supercharging capsule 4 and side neck liner 2 in the friction lining groove of drum housing 3.
During normal operation, steel rope 8 is pressing liner 5 radially to overcome the power of spring 6, it is moved down, because perfusion fluid in the supercharging capsule 4, so the chamber, both sides of its two U die cavity is to 2 one power of side direction liner, make 2 pairs of steel ropes 8 of side direction liner that a pressure be arranged, steel rope 8 is subjected to the pressure of three directions, promptly radially liner 5 is given the pressure of steel rope 8, two side direction liners 2 are given the pressure of steel rope 8, thereby improve the hoisting capacity of gig, when steel rope 8 rotated near separation point with liner with drum housing, than drops, the elastic force of spring 6 made radially that liner 5 moves up to steel rope to liner, the side direction liner 2 of both sides is left away to both sides, so that steel rope 8 can separate with liner smoothly.
