SU989645A1 - Device for electric power supply to movable mechanism - Google Patents

Description

The invention relates to lifting and transport machinery, namely, devices for supplying electrical energy to a moving object, such as a hoist.

A device for supplying electric power to a movable mechanism is known, which contains carriages installed with the possibility of moving along the mechanism’s travel paths / interconnected by a cable with an energy carrier attached thereto. The device’s construction allows the energy carriers to twist when the carriages approach each other, which affects its reliability.

It is also known a device for supplying electric power to a movable mechanism, comprising carriages mounted for movement along a rail, connected in pairs by articulated links with an energy carrier 1.21 fixed to them.

A disadvantage of the known device is the limited functionality due to the impossibility of their use for supplying energy to a moving object moving along a curvilinear running gear.

In addition, as a result of the unequal reshaping of the carriages, the energy carrier is unevenly bent, and this reduces its strength and, ultimately, affects its reliability.

The closest to the proposed technical entity is a device containing an energy carrier,

10 mounted on pairs of mounted links articulated at one end by means of a hinge knot and connected at the other with rollers mounted with rewinding 5 along the direction Tsei Z.

However, this device is not reliable enough and has limited functionality.

The purpose of the invention is to increase reliability while expanding operational capabilities.

. The goal is achieved by the fact that in a device for supplying electric power to a mobile mechanism containing an energy carrier fixed at times, displaced by pairs of links articulated at one end by means of a hinge assembly and connected at the other end with rollers mounted 30 connected to the rollers, the ends of the links of neighboring pairs are interconnected by a gear, while the hinge assembly of each pair of articulated links is made with elements that are installed with the possibility ( At least relatively two orthogonal axes are drawn in. Fig. 1 shows the proposed device, and Fig. 2 shows section A-A in Fig., 1 in Fig. 3 shows section B-B in Fig. -1. The rolling mechanism contains rollers 1- with tapered flanges located on guide 2. Rollers 1 are pairwise connected to each other by articulated links 3 and 4 The links have a flexible energy source 5, and toothed sectors 6 are attached to the ends of links of adjacent pairs and 7, which are engaged with each other. The hinge assembly 8, each pair of articulated links 3 and 4, includes two forks 9 and 10, the planes of which are rotated one with respect to the other by 90, and the fingers 11 and 12 installed mutually perpendicularly in the insert 13 and pivotally connected to the ends of the forks 9 and 10. Link 3 and 4 are equipped with bushings 14 and 15, covering the bearing pins of the forks 9 and 10. The device operates as follows. When moving a movable object (not shown), the forced movement is transmitted to all rollers 1 moving along guide 2 by means of articulated links 3 and 4, which unfold together with gear sectors 6 and 7 rigidly mounted on their ends. between the rollers when they move and along the guide 2, the same value occurs. When moving a moving object along curvilinear paths, the hinge assemblies 8, each of which provides two single-motion rotational movements to the articulated links around the mutually perpendicular axes 11 and 12, carry out the computation of the angular distortions of the articulated weight. additionally carry out the bearing pins of the forks 9 and 10 by turning them in the sleeves 14 and 15. When the moving object moves backward, all the links of the hinge suspension are simultaneously folded together In addition to energy carrier 5, the number of links of the hinge suspension is selected depending on the length of the running tracks of the moving object. Due to the equal size of the links of the links and the toothed sectors that are in engagement with each other, the device for supplying energy to the moving mechanism constantly maintains the stability of geometrical dimensions, which are not disturbed also by its j movement along a curvilinear guide, due to the double-movable hinge of each pair of articulated links and this eliminates the unevenness of the bend of the energy carrier, which increases its strength and reliability, the claims of the device for supplying electricity to the mobile a mechanism comprising an energy carrier mounted on pairs of links arranged at one end by means of a hinge assembly and connected at the other end with rollers mounted for movement along a guide, characterized in that, in order to increase reliability while expanding operational capabilities, the ends of the links of adjacent pairs connected to the rollers are interconnected by a gear drive, while the articulated node of each pair of articulated links is made with elements installed You can rotate at least two orthogonal axes.
