[0026] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The straight disk mechanical counter type pre-deformer of the present invention has a structure as follows Figure 1 , Figure 2 and Figure 3 As shown, it includes a device connecting flange 1, a flange main shaft 2 and a plurality of supporting claw plates 3;

[0028] The equipment connection flange 1 is composed of front and rear connection flanges and an intermediate cylindrical sleeve. The rear flange is positioned by a stopper and connected to the rope closing device by bolts. The front flange is positioned by a stopper and connected to the rear plate of the pre-deformer flange main shaft 2 by bolts.

[0029] like Figure 2As shown, the flange spindle 2 is composed of a front disk, a rear disk and a middle spindle. The front and rear disks are of the same size and have a "petal-like" appearance. Each "petal" corresponds to a supporting claw disk 3. The number of "petals" is determined by the number of outer strands of the twisted wire rope. The gaps between the "petals" are arc-shaped grooves 5, which are used to pass the outer strands of the wire rope and reduce weight. The number of arc-shaped grooves 5 is determined by the number of outer strands of the wire rope. The rear disk of the flange spindle 2 and the front flange of the equipment connection flange 1 are matched with the stopper and connected by bolts. The inner surfaces of the front and rear disks of the flange spindle 2 are engraved with slideway grooves, and linear through holes with equal spacing are evenly distributed on the slideway grooves. The diameter of the pre-deformer end disk can be adjusted in conjunction with the supporting claw disk 3. The slideway groove cooperates with the support claw plate 3, and the linear through hole on the slideway groove is connected with the two ends of the support slide plate of the support claw plate 3 by bolts, which is used to adjust the radial position of the support claw plate 3, change the end plate diameter of the pre-deformer, and ensure the twist length and twist distance of wire ropes with different diameters. The front plate of the flange main shaft 2 cooperates with the bracket connecting sleeve 4 by means of a stopper and is connected by bolts. The inner and outer diameters of the middle main shaft of the flange main shaft 2 are consistent with the inner and outer diameters of the equipment connection flange 1. The main shaft is a hollow cylindrical shape, and a strip through hole is processed on the outer surface to observe the passage of the internal steel core, and has a weight reduction effect;

[0030] The supporting claw plate 3 includes an irregular polygonal supporting slide plate, a depression adjustment mechanism is arranged in the middle of the supporting slide plate, and roller spacing adjustment mechanisms are symmetrically arranged near the two ends of the supporting slide plate. The two ends of the supporting slide plate are respectively connected to the linear through holes on the front and rear plate slide grooves of the flange main shaft 2 by bolts.

[0031] like Figure 4 As shown, the pressing amount adjustment mechanism includes an adjusting screw, an intermediate slider connected to the adjusting screw, and a middle wheel connected to the intermediate slider. The end of the adjusting screw of the pressing amount adjustment mechanism is matched with the horizontal mechanical counter 6 by the shaft hole and is connected and fixed by a locking rivet 8, as shown in FIG. Figure 5 As shown; the roller gap adjustment mechanism includes an adjusting screw, an end slider connected to the adjusting screw, and a side wheel connected to the end slider. The end of the adjusting screw of the roller gap adjustment mechanism cooperates with the longitudinal mechanical counter 7 using the shaft hole and is connected and fixed by a locking rivet 8.

[0032] The mechanical counter adopts a typical gear fitting transmission chain structure, including a display device, which is composed of a digital pointer or a digital roller. The mechanical counter displays a numerical value adjusted once each time the pressing screw and the roller screw rotate one circle.

[0033] The straight disc mechanical counter type pre-deformer of the present invention has the following working process: firstly, the middle wheel of each supporting claw disc 3 is adjusted to be flush with the side wheel, and the side wheel of each supporting claw disc 3 is adjusted to the middle position of the side wheel adjusting screw, and is mirror-symmetrical along the center line of the middle wheel, such as Figure 4As shown, then adjust the horizontal and vertical mechanical counter display values ​​to 300 as the "zero position", the middle wheel pressing down is "+", the middle wheel moving up is "-", the side wheel moving outward is "+", and the side wheel moving inward is "-". During the twist adjustment process of the wire rope, the mechanical counter display value is adjusted once for each rotation of the pressing screw and the roller gap screw to achieve accuracy and consistency in the adjustment of the pressing amount and the roller gap, ensuring that the twisting state of each outer layer of the wire rope is uniform.

[0034] The straight disk mechanical counter type pre-deformer of the present invention has the following advantages:

[0035] 1) The mechanical counter is connected with the screw for adjusting the pressing amount and the roller distance, so that the mechanical counter displays a value jump every time the adjusting screw rotates one circle, ensuring the accuracy of the pressing amount and the roller distance of the wire rope during the adjustment and measurement process; compared with the traditional vertical and disc pre-deformers, the structural design is more compact, suitable for use in limited installation spaces, and meets the twisting needs of pre-deformers for large and super-large wire ropes. It has strong applicability and can be promoted for use;

[0036] 2) It is suitable for the twisting of 6-strand and 8-strand steel wire ropes with a diameter of more than 40 mm. It is connected to the adjusting screw through a mechanical counter, so that the value displayed by the mechanical counter is adjusted once for each rotation of the adjusting screw, thereby ensuring the accuracy of the steel wire rope pressure reduction and roller spacing during the adjustment and measurement process. It solves the problem that in the process of twisting parameter adjustment of traditional vertical and disc pre-deformers, the roller spacing and pressure reduction corresponding to each outer strand need to be adjusted and measured separately, which leads to errors in adjustment and measurement and affects the actual quality of the steel wire rope.
