RU2259937C1 - Device for flexible connection of energy carriers to movable object - Google Patents

Abstract

FIELD: mechanical engineering.

SUBSTANCE: invention relates to means of transmission of energy to moving construction members, for instance, cranes. Proposed device includes power leaf chain and trestle. Power leaf chain with power carriers is placed on rolls for combined rolling. Said rolls are installed on trestle and are interconnected by shaft and tie-rods whose length equal to roll-to-roll distance is defined by length of tolerable supportless section of power leaf chain. Chain sprockets are cut on extreme rolls. Pitch circle diameter of sprockets is equal to diameter of roll rolling. Sprockets are intermediated by roller-bushed chain, one of which is secured on movable object and the other, on trestle. Power chain with power carriers is secured on movable object, being placed on cylindrical part of rolls for free rolling on rolls, and free rolling of rolls on trestle. Length of travel of rolls in assembly with tie-rods is equal to half of travel of movable object, and length of trestle is equal to length of travel of movable object plus overtravel margin.

EFFECT: simplified design of device for connection of energy carriers to movable object, increased service life.

Description

Known power circuit [1] for wiring hoses, cables, etc. containing a thin-walled structure of chain plates connected to each other articulated using pins.

The disadvantage of the design of the circuit is its complexity and lack of reliability in operation with significant movements of the moving object.

A device for flexible current supply to a moving object [2], containing a flexible energy carrier, blocks polyspastnyh drive, a rod having telescopically sliding sections.

A disadvantage of the known device is the unreliability of the design with significant movements of the moving object and the complexity of the telescopic mechanism with retractable sections.

A known device for supplying energy to a moving object [3], adopted by us for a prototype, containing a flexible energy carrier laid on a flexible body and connected with a moving object and a power point, a trolley, deflecting blocks and a drum, mounted on the axis of non-driven wheels and a tension block.

A disadvantage of the known device is the large joint deflection of the flexible connection and the energy carrier attached to it during significant movements of the moving object and the application of great efforts to it, since the flexible connection when moving the moving object is constantly in a tense position, which reduces the durability of the energy source due to increased resistance to movement .

The purpose of the invention is to simplify the design and increase the durability of the device.

This goal is achieved by the fact that the proposed device is equipped with a power plate chain laid on the rollers with the possibility of joint rolling, the rollers are mounted on a trestle and interconnected by shafts and rods, the length of which, equal to the distance between adjacent rollers, is determined by the length of the allowed unsupported section of the power plate chain , sprockets are cut on the extreme rollers, while the pitch diameter of the sprockets is equal to the rolling diameter of the rollers, the sprockets are interconnected, for example, by a sleeve-roller chain, fixed at one end on a moving object and the other end on a flyover, a power circuit with energy carriers is fixed on a moving object and laid on the cylindrical part of the rollers with the possibility of free rolling on the rollers, and rollers on the flyover, the length of the rollers assembled with rods is equal to half the stroke moving object, and the length of the flyover is equal to the stroke length of the moving object plus a margin for overrun.

The use of sprockets and a chain connecting them ensures constant positioning of the power plate chain and the rollers between each other.

The presence of rods allows you to maintain a constant distance during the movement of the power circuit along the rollers, equal to the allowable length of its unsupported section, eliminating damage to the power circuit at any length of its stroke.

The equality of the dividing diameters of the sprockets and the diameters of the rollers provides joint movement with the possibility of free rolling of the power circuit on the surface of the rollers without slipping, which ensures minimal wear of the elements of the power plate chain.

Figure 1 shows a diagram of the movement of the power plate chain along the rollers when moving a moving object to its extreme position.

Figure 2 shows a front view of the power circuit, rollers and overpass.

Figure 3 shows a cross section aa of the power plate chain.

Figure 4 shows a cross section BB along the trestle.

Accepted designations in the drawings:

L is the course of the moving object,

L1 - unsupported section,

L2 is the distance between the extreme rollers,

L3 - total length of the flyover.

The device comprises an overpass 1 of a frame structure, a power plate chain 2, made in the form of separate plates 3, interconnected by pins 4, energy carriers 5 (air, water, electricity, etc.), rollers 6, interconnected by rods 7 and shafts 8, sprockets 9, interconnected, for example, by a sleeve-roller chain 10, one end T.A of the chain 10 is fixed to the movable object 11, and the other end T.B of the chain 10 is fixed to the flyover 1.

The power plate chain 2 is fixed by one end of the t. In on the movable object 11, and the other end is connected to a fixed point t. With the input of energy sources 5 in the power circuit 2.

The power circuit 2 is laid on the cylindrical part D of the rollers 6 with the possibility of free rolling on the rollers 6.

The stroke length of the rollers 6 complete with rods 7 is equal to half the stroke L of the movable object 11, and the length L3 of the trestle 1 is equal to the stroke length L of the movable object 11 plus the margin for overrun (Figs. 1 and 2).

When moving the moving object 11, the rollers 6 roll along the overpass, and the power circuit 2 freely rolls along the cylindrical part of the rollers 6 without sliding. In this case, the unsupported section of the power circuit L1 = const.

The proposed device has a simple design and ensures minimal wear of the power plate chain, and also eliminates its damage during operation.
