Description

Technical Field

[0001] This utility model relates to the technical field of wire rope production equipment, and in particular to a wire rope pretensioning device. Background Technology

[0002] In the production of wire rope, the stranding process is an indispensable step. On the wire rope stranding production line, in order to reduce the internal stress between strands and the unevenness of the twisting after stranding, and to improve the fatigue life of the wire rope, the wire rope needs to undergo a pre-tensioning process using a pre-tensioning device to make its structure and various mechanical properties more stable. Most existing pre-tensioning devices can only pre-tension one wire rope at a time, which leads to low processing efficiency.

[0003] Chinese Patent Publication No. CN207891637U, published on September 21, 2018, discloses a wire rope pre-tensioning device, comprising a base. The base is characterized by a horizontal groove structure on its upper surface, and a second guide wheel and a first guide wheel at its upper left and right ends. Both the outer surfaces of the first and second guide wheels have several wire rope limiting grooves. The central axes of the first and second guide wheels are at the same height and parallel to each other. The central axis of the first guide wheel has vertically arranged grooves at both ends. The mounting plate is fixedly mounted on the base. One end of the central rotating shaft of the first guide wheel is rotatably mounted on the side wall of the mounting plate. The other end of the central rotating shaft of the first guide wheel passes through the side wall of the mounting plate and is connected to a first motor. The first motor is fixedly mounted on the mounting plate. The output shaft of the first motor is fixedly connected to the central rotating shaft of the first guide wheel. Several vertical lifting devices are arranged parallel to each other below the central rotating shaft of the second guide wheel. The disadvantage of this utility model is that the device can only handle one wire rope when performing pre-tensioning treatment, which is inefficient. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the existing technology in terms of low efficiency in processing steel wire ropes, and provides a steel wire rope pretensioning device that can simultaneously pretension multiple steel wire ropes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire rope pretensioning device, comprising:

[0007] Work board;

[0008] A cable management assembly is installed at one end of a work plate, and the cable management assembly has several cable management holes.

[0009] Tensioning components, wherein there are several tensioning components, which are installed on the working plate, and one side of the tensioning components corresponds to the wire management components;

[0010] A screwing assembly is installed at the other end of the working plate and corresponds to the tensioning assembly.

[0011] The working plate is used to install the overall device. A wire management assembly is installed at one end of the working plate. The wire management assembly separates and feeds the wire ropes. After the wire ropes are organized by the wire management assembly, several wire management holes are opened on the wire management assembly for wire feeding. Then, several tensioning assemblies are used for pre-tensioning. In order to prevent the wire ropes from separating during the pre-tensioning process, the pre-tensioned wire ropes are put into the twisting assembly to ensure that the wire ropes are more tightly connected. A wire rope release device is installed at one end of the working plate, and a wire rope collection device is installed at the other end, so that multiple wire ropes can be pre-tensioned at the same time.

[0012] Preferably, the cable management assembly includes cable management rollers and a motor. Support plates are installed on both sides of the work plate. There are two cable management rollers, with one side of each roller touching. A rotating shaft is installed at both ends of each roller, and the rollers are rotatably connected to the support plates via the rotating shafts. A gear is installed on the rotating shaft at one end of each roller, passing through the support plate. The gears on the two rollers mesh. The motor is installed on one side of the work plate, and a gear is installed on the motor shaft. The gears mesh. Each roller has several evenly distributed cable management grooves, with each groove on the two rollers corresponding to the previous one. The corresponding grooves on the two rollers form a cable management hole. The two wire-reaming rollers of the wire-reaming assembly are mounted on the support plate. The two wire-reaming rollers are pressed together. A motor mounted on one side of the working plate drives a gear to rotate. The two wire-reaming rollers rotate synchronously through the meshing of the gears on the two wire-reaming rollers. The wire rope passes through the wire-reaming hole formed by the combination of wire-reaming grooves on the two wire-reaming rollers. The compression of the wire-reaming rollers feeds the wire rope and pre-treats the wire rope to ensure its shape. Each wire-reaming hole formed by the combination of wire-reaming grooves can pass through one wire rope. This design allows for the pre-arrangement of the wire rope.

[0013] Preferably, a mounting frame is installed on the working plate. The mounting frame has a U-shaped cross-section, and tensioning components are installed on the top and both sides of the mounting frame. To effectively pre-tension the wire rope, tensioning components are installed on the mounting frame on the working plate, and then tensioning components are installed on both sides of the mounting frame. The wire rope first contacts the tensioning component closest to the wire management component before releasing from the top tensioning component of the mounting frame, and finally releasing from the tensioning component on the other side. The three tensioning components work together to make the wire rope wavy. The compression of the tensioning components pre-tensions the wire rope, and the cooperation of multiple tensioning components ensures that the wire rope is fully pre-tensioned. This design allows for sufficient pre-tensioning of the wire rope.

[0014] Preferably, the tensioning assembly includes a pneumatic cylinder and a lifting frame. The lifting frame has a U-shaped cross-section and includes a base plate and two side plates. Two side plates are respectively installed at both ends of the base plate. The lifting frame is equipped with support rods, the two ends of which are connected to the side plates on both sides of the base plate. Several evenly distributed tensioning rollers are installed on the support rods, and the tensioning rollers are rotatably connected to the support rods. Each tensioning roller corresponds to a wire guide hole. The lifting frame of the tensioning assembly can be raised and lowered by the pneumatic cylinder. Support rods are installed on the side plates of the lifting frame, and several rotatable tensioning rollers are installed on the support rods. The wire rope is placed in the groove of the tensioning roller and contacts the tensioning roller. During pre-tensioning after contact with the wire rope, the pneumatic cylinder drives the lifting frame to rise, and then the tensioning rollers act on the wire rope. The rolling tensioning rollers can reduce wear. This design can tension the wire rope.

[0015] Preferably, the twisting assembly includes a lifting frame, a through tube, and a second motor. The lifting frame is mounted on the work plate, and a plurality of evenly distributed through tubes are installed at the top of the lifting frame. Each through tube corresponds to a cable management hole. A twisting tube is installed inside each through tube and is rotatably connected to the through tube. A gear ring is installed at one end of each through tube, and a motor base is installed on the through tube. The second motor is mounted on the motor base, and a third gear is installed on the motor shaft of the second motor. The third gear meshes with the gear ring. A plurality of circumferentially distributed twisting lines are installed on the inner wall of the twisting tube, and the twisting lines are spiral in shape. After being processed by the tensioning assembly, the wire rope enters the twisting assembly to ensure its tightness. The lifting frame of the twisting assembly is used to ensure the height for receiving the wire rope. The wire rope enters the corresponding through pipe and is wrapped by the twisting tube inside the pipe. Then, the second motor rotates, and through the cooperation of the gear ring and the first gear, it drives the twisting tube to rotate. At the same time as the twisting tube rotates, the twisting wire inside rotates together. The twisting wire comes into contact with the wire rope, and the spiral twisting wire drives the wire rope to rotate, thus ensuring a tighter fit. This design can ensure a tight fit of the wire rope.

[0016] Preferably, a reversing rod is installed on the working plate. The reversing rod is U-shaped and corresponds to the screwing assembly. Directly inserting the wire rope processed by the tensioning assembly into the through pipe may damage it. Therefore, the reversing rod changes the direction of the wire rope, ensuring that it can enter the screwing assembly. This design allows for changing the direction of the wire rope.

[0017] The beneficial effects of this utility model are: it can pre-tension multiple wire ropes at the same time, can pre-sort the wire ropes, can fully pre-tension the wire ropes, can tighten the wire ropes, can ensure the tight fit of the wire ropes, and can change the direction of the wire ropes.

The support rod 35 is provided with a number of evenly distributed tensioning wheels 36. The tensioning wheels 36 are rotatably connected to the support rod 35. The tensioning wheels 36 correspond one-to-one with the wire management holes 12.

[0033] like Figure 5As shown, the screwing assembly 4 includes a lifting frame 41, a through pipe 42, and a second motor 43. The lifting frame 41 is mounted on the working plate 1. Several evenly distributed through pipes 42 are installed at the top of the lifting frame 41. Each through pipe 42 corresponds to a cable management hole 12. A screwing tube 44 is installed inside the through pipe 42. The screwing tube 44 is rotatably connected to the through pipe 42. A gear ring 45 is installed at one end of the through pipe 42.
