Abstract

The utility model discloses a movable cable gripper which comprises a main body board (4) and a hanging seat shaft (6), wherein an upper half griping clamp (1) and a lower half gripping clamp (3) which are opposite and stagger to form a caliper shape are arranged in the position opposite to the hanging seat shaft (6) on the other end of the main body board (4). A steel cable of a ropeway is clamped firmly by the upper half gripping clamp (1) and the lower half gripping clamp (3). The utility model has the advantages of simple structure, simple and fast assembly and disassembly, time and work saving, and big cable clasping force; in addition, the damage to the steel cable of the ropeway is decreased to a maximum extent, and the use cost and the maintenance cost of the ropeway are reduced efficiently. Although the utility model works in the steel cable ropeway with large gradient over 18 DEG, the safety and the reliability of the utility model are improved obviously.

Description

A kind of movable rope clamping device

Technical field

The utility model relates to the movable rope clamping device that uses on a kind of aerial rope way, especially relates on a kind of mining industry aerial rope way for the movable rope clamping device of taking advantage of people's chair lift to use.

Background technology

For the rope clamping device of taking advantage of people's chair lift to use, be divided into fixed type and movable two classes substantially on the present domestic mining industry aerial rope way.The fixed type rope clip device is before being installed on the cableway steel rope, earlier metal sleeve is passed through the rivet rivet clasp on steel rope, and then rope clamping device is fixed on the metal sleeve with bolt, before rivet and bolt are not loosening, the safety of its work and reliability are all relatively good, its weak point is: rivet and bolt are in use loosening easily, the rope clamping device after loosening and the steel rope of motion produce slide relative, cause the work of fixed type rope clip device malfunctioning, safety and reliability are subjected to very big influence; Loading and unloading are once unclamped, the labour intensity when tighting a bolt is big, uses very inconvenient; During the rivet clasp metal sleeve, rivet has certain damage to steel rope, has increased the operation and maintenance cost of cableway on steel rope.Another kind of movable rope clamping device, product with import Germany is an example, the position that this rope clamping device contacts with steel rope is as a hook, directly hang on the steel rope of motion, the weight of chair lift end produces friction force between the contact surface of hook and steel rope, in the gradient of wire cableway less than 15 o'clock, described friction force can balance chair lift end the component that produced at the steel rope direction of fall of weight, guaranteed that movable rope clamping device and steel rope do not produce slide relative, safe and reliable, load and unload easy to use.Its weak point is that above-mentioned component has surpassed friction force widely, has destroyed equilibrium of forces, makes to produce slide relative between hook and the steel rope, causes the rope clamping device operational failure when the gradient of wire cableway is spent greater than 18, when serious safety misadventure may take place.

Summary of the invention

The utility model is intended to overcome the deficiencies in the prior art, provide a kind of simple in structure, reduce loading and unloading labour intensity effectively, easy for operation simple, can reduce and reduce the operation and maintenance expense of cableway to greatest extent, particularly still have very high safety and the high movable rope clamping device of reliability in the application of the heavy grade wire cableway more than 15 degree.

The purpose of this utility model is achieved by following technical proposals: it comprises main board, the chair lift axle, and an end of the solid main board of chair lift axle is provided with two in opposite directions at the main body other end, and dislocation forms first armful card and second armful card of clamp shape.

The utility model can also be realized in the following manner: the centre at first armful card and second armful card is provided with rope blocking plate, is provided with position-limited lever in the middle part of main board.

Mode of operation: on the chair lift axle of the movable rope clamping device of the utility model, install chair lift, rope clamping device is toppled over to one side, under the effect of position-limited lever, first armful card of dislocation formation clamp shape and the line of centers of second armful card are parallel with the cableway steel rope of motion substantially, lift and mobile chair lift, allow the steel rope of motion lean against on the rope blocking plate, the steel rope of motion is fallen among the interior circular arc scope of first armful card and second armful card, put down chair lift, under the combined action of chair lift end weight and steel wire rope tension, make first armful card and second armful card produce the power of backing pressure respectively to the cableway steel rope, steel rope is blocked firmly, its movable rope clip module force is directly proportional with load-carrying.

The utlity model has following advantage: simple in structure, load and unload simple and fast, save time and save trouble, movable rope clip module force is big, reduced damage to greatest extent to the cableway steel rope, reduced the operation and maintenance cost of cableway effectively, even work in greater than the heavy grade wire cableway more than 18 degree, its safety and degree of reliability significantly improve.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a birds-eye view of the present utility model;

Fig. 3 is a then view of the present utility model:

Among the figure: first armful of 1-card, 2-rope blocking plate, second armful of 3-card, 4-main board, 5-position-limited lever, 6-chair lift axle.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, 2, chair lift axle 6 is fixed on an end of main board 4; First armful card 1 and second armful card 3 are arranged on the other end of main board 4, first armful card 1 and second armful card 3 on same line of centers, they mutually in opposite directions, dislocation forms the clamp shape, the dislocation distance of first armful card 1 and second armful card 3 is determined by the diameter of cableway steel rope.

Centre at first armful card 1 and second armful card 3 is provided with rope blocking plate 2, and its effect is to lead for interior elliptic arc that steel rope falls into half armful of card 1 and second armful card 3.

Be provided with position-limited lever 5 in the middle part of main body 4, the distance of it and chair lift axle 6 determines that by the scantling of structure of chair lift position-limited lever 5 is used for limiting the angle that the utility model rotates on chair lift.

After adopting the utility model, at first chair lift is fixed on the chair lift axle 6, rope clamping device is swung on one side, effect at position-limited lever 5, first armful card 1 that making misplaces forms the clamp shape and the line of centers of second armful card 3 are parallel with the steel rope that moves substantially, lift and mobile chair lift, allow the steel rope of motion come on the rope blocking plate 2, steel rope is fallen among first armful card 1 and second armful card 3 interior elliptic arcs, put down chair lift, under the combined action of chair lift end weight and cableway steel wire rope tension, first of dislocation armful 1 pair of steel rope of card applies downward pressure, and 3 pairs of steel ropes of second armful card apply holder power upwards, the steel rope of cableway is firmly blocked, even on greater than the heavy grade wire cableway more than 18 degree, use, can not slide yet, its safe and reliable degree improves greatly.If unload movable rope clamping device of the present utility model, as long as upwards slightly lift chair lift, movable rope clamping device is swung on one side, under the effect of position-limited lever 5, first armful card 1 of dislocation formation clamp shape and the line of centers of second armful card 3 are parallel with the steel rope of motion substantially, continue to move the chair lift of lifting, steel rope is shifted out among first armful card 1 and second armful card 3, at last chair lift and movable rope clamping device of the present utility model are unloaded down from the wire cableway of motion together.
