SU823705A1 - Clamp for rubber-rope band - Google Patents

Description

The invention relates to general engineering, in particular to load lifting, and, more specifically, to equipment for carrying out work on hanging and replacing rubber cable cords in use (as balancing ropes, in 1x multi-rope mines.

A rope clamp is known, consisting of two movable parts with grooves forming a cavity for accommodating the rope therein. Parts of the body are fastened by means of connecting elements and strung diagonally with a compression spring l.

The disadvantage of this clamp is that the clamping force of the rope with the moving parts of the hull depends on the amount of tension in the rope, which reduces the reliability of its operation. At low values of the stretching force. In addition, the clamp design does not allow the rope to move freely through it.

Known clamp, comprising a housing in which a rotary cam, interacting with its working surface with one of the clamping jaws. The profile of the cam's working surface is limited by the plane passing through the axis of its rotation and chamfers located at an angle f2 to it. Such a cam design provides a response speed per mm.

However, the amount of clamping of the cable (rope) with sponges is directly dependent on the amount of force applied to the leash of the steering cam.

S In the clamp of such a construction, to hold the cable it is necessary to apply a constant force to the leash of the steering cam, and even more so if the tension of the cable is greater.

The purpose of the invention is to improve the performance of the clamp by reducing the clamp on force of the clamp and completely removing it when the tape is clamped. 38 as well as increased reliability of holding the tape. The goal is achieved by the fact that the clip is provided with a glass mounted in the housing with the ability to move in the direction of the tape associated with one of the clamping guards, 0ok.and in contact with the cam, while both sponges are provided with return springs. At the firm. i schematically depicts the available clamp; In FIG. 2, section A-A in FIG. 1. The clamp includes a housing 1 in which the upper clamping sponge 3 and the movable cup 4 with the guide 5 and the lower sponge are mounted on the guides 2 6. The guides 2 are installed on one side in the case of the other 7. The guides 5 are one side mounted in a movable cup 4, the other in the bar 8. The clamping jaws 3 and 6 are equipped with return springs 9 and adjustable - 10 h. protection. In the lower part of the body 1 there is a rotary shaft 11 with an eccentric 12 and a leash 13. The eccentric 12 of the rotary shaft 11 its surface is in contact with the mobile station 4 and clamps 14. The direction of the door at an angle of self-wedging to the axis of the passing tape 15 creates for the upper clamping jaw 3 guides 16 fixed to the housing 1, and for the lower clamping jaw 6 guides 17 of the movable cup 4. Clamping jaws 3 and 6 have a lining 18, which is fixed with the help of pins 19. The laths 7 and 8 are attached to housing i and to glass 4 with the help of bolts 20. The clamp works as follows: In the gap between clamping jaws 3 and 6 installed in housing B, p passes tape 15 , the leash 13 turns the shaft 11, an eccentric 12 of which moves the movable cup 4 with the lower clamping sponge 6. In this case, the distance between the clamping jaws is reduced and the ribbon is clamped with minimal effort, sufficient for 5 clamping jaws 3 and 6, due to the friction forces between the moving belt 15 and the lining 18 fastened with the pins 19 began to be carried along guide rails 16 and 17 before self-sealing. In order to release the clamping jaws 3 and 6 and to release the belt 15, the rotation shaft 11 is turned in the opposite direction by the driver 13. At the same time, the eccentric 12 of the rotary shaft, interacting with the clamps 14, lowers the movable cup 4 with the lower sponge 6. The return springs 9 return the sponge 3 and 6 along the guides 2 and 5 to the initial position until the adjusting stops 10. The springs 9 returns protect the self-jamming of the moving tape in case of accidental contact with the clamping jaws. The application of the proposed clamp provides a reduction in the time of clamping and unclenching the tape while holding it in weight, safety of work, reduction of labor costs in the production of works for hanging and replacing, balancing rubber-rope tapes. Formula, invention Clamp for rubber cable, comprising a housing, a shaft with a cam and clamping jaws located on either side of the tape with lining I characterized in that, in order to increase reliability and efficiency, by reducing the activation force and removing it when the tape is clamped, it is provided with a glass mounted in the housing for movement in the belt between the gripping jaws and in contact with the cam, while the jaws are provided with return springs.
