Coy tape with a grooved profile. The coupling of the running and running branches of the tape in the form of a loop is removed with the help of a roller 8 mounted on the axis of the shaft 9 and the JO bracket with a tension device (not shown in the drawing). In the groove-shaped profile of the liner 7, the friction turns of the rope 11 are placed. Gears 12 are installed on all the frills on one side, the gears of the even pins are placed on one side of the drum, and the gears of odd nafedok on the other side of the drum. The gears J2 of the finishes b are in engagement with the center al of the fixed sun gears 13 and 14, mounted and fixed in the housings 4 and 5. On the inside diameter of the screw thread of the attachments 6 and on the working surface of the roller 8 the tension device is known in a known manner (knurled a) teeth 15 and 16, similar to teeth 17, made on the surface of lining 7, in contact with workpieces 6 and roller 8. Devices registering the synchronism of rotation of the drum drive shaft and the nat shaft are attached to the ends of the shafts 3 and 9 of the drum and the roller B Nogo roller (registriruyupsche device not shown in the drawing) Traction drum works as follows. Preliminarily, the working support surface of the ram consisting of evenly distributed flanges 1 and 2 of screw fittings 6 around the circumference is wound lining 7 made in the form of a flexible tape with a grooved profile. The running and rolling branches of the lining form a loop pulled by the tensioner rollers of known design. The i. Toe 17 of the lining 7 is engaged with the teeth 15, made on the inside diameter of the screw cutting of the attachments b, and with the teeth 16, made on the working surfaces of the roller 8 In the trough-shaped profile of the futher coat 7, the turns of friction of the rope 11 are laid. When the shaft 3 rotates, the flanges 2 and 1 rotate together with the fixings used with screw thread b. At the same time, the gears 12, which have an equal number of teeth with a sun disc, gears 13 and 14, which are mounted on the ends of the allotments, engage with the latter, resulting in the rotation of the bar with screw thread rotates around the axes with the rotation of the flange 1 and 2 rotational speed equal to the frequency of rotation of the flanges 1 and 2. In the process of rotating the bababan and laying the turns of the lining friction 7 (with the turns of the friction of the rope 11 laid into it) into cutting of the attachments 6, the turns of the friction are shifted along the drum axis in one direction Own axes of the axes cause the friction turns of the protective element to be shifted by the same amount in the opposite direction. As a result, the turns of the lining 7 (together with the turns of the J1 friction rope put into it) occupy a fixed position on the accessories. This ensures the normal operation of the drum. - The presence of teeth 15 and 16, made on the inner diameter of the screw cutting of the adaptations b and on the working surface of the roller 3 of the tensioning device, which engages with the teeth 17, made on the surface of the lining 7, which contacts the finishing b and the roller 8, provides an increased The drum's drumming ability eliminates the slippage of the lining 7 relative to the drum and the roller 8 of the tensioning device. This provides the ability to control the slip of the lining 7 by registering the synchronism of rotation of the drive shaft, 3 and the shaft 9 of the tension roller 8. The presence of special tools to control the slip will reduce the wear of the lining and eliminate the et-o break, i.e., prevent emergency breakdown of the drum and rope.

Claims

754) ROPE DRUM by author No. 1148252, distinguished by the fact that, in order to increase the reliability of its operation, the tensioner roller is made with teeth interacting with the teeth of the lining,

V

The invention relates to hoisting equipment, and in particular to traction drums.

According to the main author. St. No. 1148252, there is known a guiding drum containing flanges mounted on the shaft, in which cylindrical rotary attachments with spiral grooves are arranged uniformly around the circumference and covered by a lining made in the form of an endless chain on which a traction rope is placed that envelopes the tensioner roller, moreover, the lining is made teeth interacting with teeth made in spiral grooves of cutting.

A disadvantage of the known drum is the relatively low reliability.

The purpose of the invention is to increase the reliability of its work.

To achieve this, the roller of the tensioner is made with teeth interacting with the teeth of the lining, 'ί The drawing shows a general view of the i-guide drum of the proposed design.

The drum consists of. two flanges 1 and

2 mounted on the drive shaft 3. The shaft 3 is supported by bearings housed in housings 4 and 5, and attached to the drive by means of a coupling (not shown). Between the flanges 1 and 2, cylindrical adjustments 6 with screw thread are evenly distributed around the circumference. The cradles 6 are covered by a lining 7 made in the form of a flexible ₄ tape with a groove-like profile.

The pairing of the running and running branches of the tape in the form of a loop is pulled by means of a roller 8 mounted on the axis of the shaft 9 and the bracket 10 by the force of the tensioning device (not shown in the drawing). The friction coils of the rope 11 are placed in the gutter-shaped profile of the lining “b 7”. Ι

On all the adjustments, gears 12 are installed on one side, and even gears of even adjustments are placed on one side of the drum, and odd gears are central fixed gears 13 and 14, which are fixed in the housing on the inner diameter

3,1198,877 adjustments - on the other side of the b'araban. The gears J2 of the attachments b are meshed with the solar novelty sahs 4 and 5.

screw cutting of the adjustments 6 and on the working surface of the roller 8 of the tensioner in a known manner teeth 15 and 16 are grinded (knurled). Similar teeth 17 are made on the surface of the lining 7 in contact with the adjustments 6 and the roller 8. To the ends of the shafts 3 and 9 of the drum and roller 8, devices are registered that register the synchronization of rotation of the drive shaft of the drum and the shaft of the tension roller (recording devices are not shown in the drawing).

The traction drum operates as follows.

Preliminarily, on the working supporting surface of the ram, consisting of uniformly: circumferentially arranged flanges 1 and 2 of trim 6 with screw thread, wrap the lining 7, made in the form of a flexible tape with a groove profile. The running and running branches of the lining form a loop drawn using the rollers of a tensioning device of known design /. The teeth 17 of the lining 7 mesh with the teeth 15, made on the inner diameter of the screw thread cutting b, and with the teeth 16, made on the working surface of the roller 8, In the groove-shaped profile of the lining 7 are placed the friction coils of the rope 11. When the shaft 3 rotates, the flanges 2 and 1 together with the installed counterparts 6 with screw thread.

In this case, gears 12 installed at the ends of the fittings, having an equal number of teeth with fixed sun gears 13 and 14, mesh with the latter, as a result of which, when the drum with flanges 1 and 2 rotates, the screw cuttings 6 rotate around their own axes with a rotation frequency equal to the speed of rotation of the flanges 1 and 2. During the rotation of the ba-dough and the laying of friction coils of the lining 7 (with friction coils 11 inserted into it) in the cutting of cladding 6, the friction coils are shifted along the drum axis in one direction, and when turning the claddings in the district of its own axes, the friction coils of the protective element are shifted by the same amount in the opposite direction. As a result, the friction coils of the lining 7 (together with the friction coils of the rope 11 laid in it) occupy a permanent position on the claddings. This ensures the normal operation of the drum. ’. ·

The presence of teeth 15 and J6, made on the inner diameter of the screw thread 6 and on the working surface of the roller 3 of the tensioner, engaged with the teeth 17, made on the surface of the lining 7 in contact with the work ^ 6 and the roller 8, provides increased traction of the drum eliminates slippage of the lining 7 relative to the trim 6 of the drum and the roller 8 of the tensioner. This makes it possible to control the slippage of the lining 7 by registering the synchronization of rotation of the drive shaft 3 and the shaft 9 of the tension roller 8.

The presence of special devices to control slippage will reduce lining wear and eliminate eto breakage, i.e. prevent emergency failure of the ba, raban and rope.
