Description

Technical Field

[0001] The utility model relates to the technical field of wire rope tension adjusting devices, and more specifically, to a wire rope tension adjusting device with preheating. Background Art

[0002] A wire rope is a helical wire bundle formed by twisting steel wires that meet the requirements of mechanical properties and geometric dimensions together according to certain rules. It consists of steel wires, a rope core, and lubricating grease, and has the characteristics of high strength, light self-weight, stable operation, not likely to break suddenly as a whole, and reliable work. During the production process of wire ropes, the wire ropes need to be wound around a collecting wheel, and a tensioning device is usually provided between the wire drawing machine and the collecting wheel. The tensioning device is used to tension the steel wires so that the steel wires can be smoothly wound around the collecting wheel.

[0003] Among them, the patent with the publication number CN216583458U discloses a wire rope tension adjusting device, belonging to the technical field of tension adjustment. It includes an adjustment box and an oil cylinder fixed to the bottom of the adjustment box. A plurality of guide rollers are rotatably installed on the inner wall of the adjustment box along its length direction, and a positioning piece is rotatably connected to the end of the guide roller; a positioning box is fixed to the inner wall of the adjustment box; a first chute is opened on the inner wall of the positioning box, and the positioning box is slidably connected with a plug rod along its length direction through the first chute; a slot for inserting the plug rod is opened on the side wall of the positioning piece.

[0004] When this structure is in use, during the process of the positioning piece inserting into the positioning box, the bottom of the positioning piece first contacts the abutting piece through the second inclined surface. After being pressed, the abutting piece moves towards the inside of the third chute. During the movement of the abutting piece, it presses the limiting piece through the second inclined surface and pushes the limiting piece to move upward for adjustment. However, such operation steps are relatively complex, not easy to automatically adjust appropriately according to its toughness, and not easy to preheat, resulting in a temperature difference between the wire rope after production and the device. The thermal expansion and contraction phenomenon caused by the temperature difference may cause changes in the twisting structure of the wire rope, such as changes in the lay length and relative positions between the rope core and the steel wires. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a wire rope tension adjusting device with preheating, aiming to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A wire rope tension adjusting device with preheating, including a horizontal shaft, and support adjustment components are arranged at both ends of the horizontal shaft;

[0007] The support adjustment component includes a support seat arranged at one end of the horizontal shaft, a lead screw is fixedly arranged on one side of the support seat, and a position-adjustable slide plate is sleeved on the lead screw;

[0008] A support rod is rotatably connected to the outside of the support base through a pin, and a heating plate is provided at one end of each support rod. A support wheel is provided on the heating plate. A plurality of connecting pieces are rotatably connected to the outside of the sliding plate through pins, and each connecting piece is located on one side of the corresponding support rod. One end of the connecting piece extends to the support rod and is rotatably connected to the support rod through a pin. An internal thread sleeve is provided on one side of the sliding plate. The internal thread sleeve is sleeved on the outside of the lead screw, and the internal thread sleeve is threadedly connected to the lead screw;

[0009] It can be seen that in the above technical solution, the heating plate preheats the support wheel to avoid the change of the stranding structure of the wire rope caused by the thermal expansion and contraction phenomenon caused by the temperature difference. According to the needs, by rotating the internal thread sleeve, when the internal thread sleeve rotates on the lead screw, the displacement will abut against one side of the sliding plate, and the position of the sliding plate will be changed. When the sliding plate is displaced, the distance between the sliding plate and the limiting plate is adjusted, and then the displacement stroke of the sliding plate between the internal thread sleeve and the limiting plate can be adjusted

[0010] Optionally, in a possible implementation manner, a limiting plate is provided on the side of the sliding plate away from the internal thread sleeve. The limiting plate is located at one end of the lead screw and is detachably connected to the lead screw through a bolt. A return spring is provided between the limiting plate and the sliding plate. The return spring is sleeved on the outside of the lead screw. One end of the heating plate is installed with a driving motor through a bolt, and a heat insulation plate is provided between the driving motor and the heating plate. The output end of the driving motor penetrates through the heat insulation plate and the heating plate and extends to the support wheel;

[0011] It can be seen that in the above technical solution, the displacement stroke of the sliding plate is limited to adjust the expandable stroke of the return spring, so that when the support rod rotates along the axis point of the connection between the support rod and the support base under force, it drives the connecting piece to deflect and drives the sliding plate to displace. After the elastic force of the return spring itself drives the sliding plate to reset, the function of supporting the wire rope is realized, and then the function of tension adjustment is realized.

[0012] The technical effects and advantages of the present utility model:

[0013] By setting the support adjustment component, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the wire rope is guided and supported by the support wheel, and at the same time, the driving motor is started to drive the support wheel to rotate for conveying it. The heating plate preheats the support wheel to avoid the change of the stranding structure of the wire rope caused by the thermal expansion and contraction phenomenon caused by the temperature difference.

[0014] By restricting the displaceable stroke of the skateboard, the extendable stroke of the return spring is adjusted, so that when the support rod is stressed and rotates along the axis point of the connection between the support rod and the support seat, the driving connector deflects and drives the skateboard to displace. After that, the skateboard is reset by the elasticity of the return spring itself, realizing the function of supporting the steel wire rope, and then realizing the function of tension adjustment, which is easy to adjust appropriately according to the toughness of the steel wire rope.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As shown in the attached Figures 1-4The shown wire rope tension adjusting device with preheating uses a support adjusting assembly arranged on the horizontal shaft 1. After the driving motor 11 is started, the driving support wheel 10 rotates to convey the wire rope, and the heating plate 9 preheats the support wheel 10 to avoid the change in the stranding structure of the wire rope caused by the thermal expansion and contraction phenomenon due to temperature difference. By restricting the displaceable stroke of the sliding plate 4, the expandable stroke of the return spring 8 is adjusted. When the support rod 6 is stressed and rotates around the axis point of the connection between the support rod 6 and the support base 2, the driving connecting piece 5 deflects and drives the sliding plate 4 to displace. Then, the elastic force of the return spring 8 itself drives the sliding plate 4 to reset, realizing the function of supporting the wire rope, and then realizing the function of tension adjustment. The specific structure of the assembly is as follows;

[0023] The support adjusting assembly includes a support base 2 arranged at one end of the horizontal shaft 1. A lead screw 3 is fixedly arranged on one side of the support base 2, and a sliding plate 4 with adjustable position is sleeved on the lead screw 3;

[0024] The outside of the support base 2 is rotatably connected with a support rod 6 through a pin. One end of each support rod 6 is provided with a heating plate 9, and a support wheel 10 is arranged on the heating plate 9. The outside of the sliding plate 4 is rotatably connected with several connecting pieces 5 through pins, and each connecting piece 5 is located on one side of the corresponding support rod 6. One end of the connecting piece 5 extends to the support rod 6 and is rotatably connected with the support rod 6 through a pin. An internal thread sleeve 12 is arranged on one side of the sliding plate 4, and the internal thread sleeve 12 is sleeved on the outside of the lead screw 3 and is threadedly connected with the lead screw 3;

[0025] A limit plate 7 is arranged on the side of the sliding plate 4 away from the internal thread sleeve 12. The limit plate 7 is located at one end of the lead screw 3 and is detachably connected with the lead screw 3 through a bolt. A return spring 8 is arranged between the limit plate 7 and the sliding plate 4, and the return spring 8 is sleeved on the outside of the lead screw 3. One end of the heating plate 9 is installed with a driving motor 11 through a bolt, and a heat insulation plate is arranged between the driving motor 11 and the heating plate 9. The output end of the driving motor 11 penetrates through the heat insulation plate and the heating plate 9 and extends to the support wheel 10.

[0026] When using according to the above structure, the staff installs the device at the specified position. When tension-adjusting the produced wire rope, the wire rope is guided and supported by the support wheel 10. At the same time, the driving motor 11 is started to drive the support wheel 10 to rotate for conveying, and the heating plate 9 preheats the support wheel 10 to avoid the change in the stranding structure of the wire rope caused by the thermal expansion and contraction phenomenon due to temperature difference.

[0027] According to the requirement, by rotating the internal thread sleeve 12, when the internal thread sleeve 12 rotates on the lead screw 3, its displacement will abut against one side of the sliding plate 4, and the position of the sliding plate 4 will be changed. When the sliding plate 4 displaces, the distance between the sliding plate 4 and the limit plate 7 is adjusted, and then the displaceable stroke of the sliding plate 4 between the internal thread sleeve 12 and the limit plate 7 is adjusted.

[0028] The displaceable stroke of the sliding plate 4 is restricted to adjust the expandable stroke of the return spring 8, so that when the support rod 6 is stressed and rotates along the axis point of the connection between the support rod 6 and the support base 2, the driving connector 5 is deflected and the sliding plate 4 is displaced. Through the elasticity of the return spring 8 itself, the sliding plate 4 is driven to reset, realizing the function of supporting the wire rope, and then realizing the function of tension adjustment.

[0029] Different from the prior art, the present application discloses a wire rope tension adjustment device with preheating. The driving motor 11 is started to drive the support wheel 10 to rotate for conveying, and the heating plate 9 preheats the support wheel 10 to avoid the change of the stranding structure of the wire rope caused by the thermal expansion and contraction phenomenon caused by the temperature difference. The displaceable stroke of the sliding plate 4 is restricted to adjust the expandable stroke of the return spring 8, so that when the support rod 6 is stressed and rotates along the axis point of the connection between the support rod 6 and the support base 2, the driving connector 5 is deflected and the sliding plate 4 is displaced. Through the elasticity of the return spring 8 itself, the sliding plate 4 is driven to reset, realizing the function of supporting the wire rope, and then realizing the function of tension adjustment.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
