Description

TECHNICAL FIELD

[0001] The utility model relates to tension device technical field, concretely relates to a novel chain type tension belt damping block structure. BACKGROUND

[0002] In the twisting process of the steel wire rope, the laying device of the stranding machine should keep stable laying tension to ensure that the steel wire rope strands are uniform, and the steel wire is not twisted and knotted. Once the steel wire rope jumps out of the guide wheel due to uneven tension, it will cause a series of problems such as fatigue damage, fracture, poor straightness, unstable jumping tension, accelerated wear, equipment damage, and reduced production efficiency.

[0003] The device for controlling the laying tension of the steel wire rope currently generally includes a damping disc, a tension belt including a chain, which is sleeved on the outer edge of the damping disc to give the damping disc a predetermined pressure, a plurality of damping blocks arranged on the chain, which are clamped between the chain and the outer edge of the damping disc, the predetermined pressure applied to the damping disc by the chain being transmitted to the damping disc through the damping blocks, and a control assembly for controlling the pressure applied to the damping disc by the tension belt. When the damping disc rotates with the winding I-beam, a predetermined frictional resistance is generated between the damping disc and the damping blocks, thereby controlling the rotation speed of the laying I-beam and achieving the purpose of controlling the laying tension. For example, Chinese patent CN201410443310.0, entitled "Novel chain type steel wire tension belt", Chinese patent 201711155871.0, entitled "Steel wire rope stranding machine and its laying tension control device", etc. In the existing tension belt, the damping blocks are generally copper-based metallurgical damping blocks, which are resistant to high temperature, have fast heat dissipation, effectively increase the friction degree, ensure wear resistance and slip resistance, and prolong the service life. The copper-based metallurgical damping blocks are provided with an open line groove on one side of the back, and the damping blocks are connected together through the chain. The copper-based metallurgical damping blocks are resistant to high temperature, have fast heat dissipation, effectively increase the friction degree, ensure wear resistance and slip resistance, and prolong the service life.

[0004] Most of the manufacturers of the products on the market also basically adopt similar design, but in the actual use process, combined with the operation of the tension belt, the tension is not stable. It is found that the essence of controlling the tension belt to apply pressure to the damping disc through the control assembly is that the movable end of the control assembly drives the tension belt to tighten or loosen, controls the friction degree of the tension belt and the damping disc, and then controls the rotating speed of the damping disc. During production, frequent tightening and loosening movements are required to continuously adjust the rotating speed of the damping disc. In physics, the size of the friction force can be calculated by the formula F=UN, wherein F represents the friction force, U is the friction coefficient, and N refers to the normal pressure of the contact surface. When the tension belt is loosened, the closer to the movable end of the damping block, the greater the fluctuation of the normal pressure N of the contact surface of the damping block and the damping disc, and the abnormal fluctuation of the normal pressure causes the pressure loss, which is not conducive to the stability of the tension. This phenomenon is particularly prominent in the case of small torque and high frequency fluctuation of the disc bottom, which seriously affects the stability of production.
