Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, and particularly relates to a winding driving device for ropes. Background Art

[0002] Natural draft counterflow wet cooling towers are widely used in industries such as energy, petrochemical, and metallurgy. They exchange heat between the cooling water carrying waste heat and the wet air in the tower, transferring the waste heat to the wet air and dissipating it into the atmosphere. Natural draft counterflow wet cooling towers generally adopt a hyperbolic tower body, supported by herringbone columns at the bottom. The air inlet at the bottom of the tower body is located between adjacent herringbone columns. The main facilities inside the tower include a water distribution system, a filler support, a splash packing, a spraying device, a water eliminator, and a sump. High towers also have a water spraying plate and a water collecting trough, etc.

[0003] Natural draft counterflow wet cooling towers mainly rely on the suction force formed by the density difference between the air inside and outside the tower to suck the cooling air from outside the tower into the tower through the air inlet at the bottom of the tower. The cooling air flows through each area inside the tower from bottom to top in turn: the rain zone (conventional tower) or through the inclined plate channel of the water collection device through the light rain zone (high tower), the splash packing area, the spraying area, the water collection area, and then is discharged into the atmosphere through the upper area of the tower body. When the cooling air passes through the rain zone or the light rain zone, the splash packing area, and the spraying area, it comes into contact with the high-temperature cooling water, absorbs the heat of the high-temperature cooling water through mass transfer and heat transfer heat exchange, thereby reducing the temperature of the high-temperature cooling water and realizing the cooling function of the cooling tower.

[0004] In cold northern regions, when the ambient air temperature is below 0°C during the winter operation of the cooling tower, icing may occur on components such as the cooling tower support and the packing. The lower the ambient temperature, the more serious the icing problem. When the ice weight is overweight, it will drag down components such as the support and the packing, causing component damage and seriously affecting the normal operation of the cooling tower. Therefore, an anti-freezing and energy-saving device needs to be installed.

[0005] In the prior art, one way to solve the winter anti-freezing problem of the cooling tower is to install an anti-freezing and energy-saving device with a windbreak curtain as the main facility at the air inlet of the natural draft counterflow wet cooling tower. A steel structure is arranged at the air inlet position of the tower body, and a windbreak curtain that can be lifted and lowered by a motor is used. A lifting rod is arranged on the windbreak curtain. By controlling the lifting of the lifting rod, the lifting of the windbreak curtain is realized. When lifting and lowering the lifting rod, one end of the steel wire rope is fixed and wound around the drum, and the other end is fixed on the lifting rod. The drum is driven by a driving mechanism such as a motor to rotate, thereby realizing the winding or unwinding of the steel wire rope, and further driving the lifting rod to lift and lower.

[0006] However, when the reel rotates forward or backward to drive the wire rope to wind, the wire rope winds around the reel. When the length of the wire rope to be wound is too long, the wire rope winds more than one circle. Since the position of the reel is fixed, it is necessary to increase the diameter or length of the drum, otherwise the winding point position of the wire rope on the drum will move left and right, resulting in a change in the position of the rope. Summary of the Invention

[0007] The purpose of the present invention is to provide a winding drive device for ropes, and solve the following technical problems:

[0008] How to prevent the position of the wire rope from changing during winding or unwinding on the reel?

[0011] It also includes a fixedly installed threaded seat. Internal threads are provided in the inner hole wall of the threaded seat.

[0012] In a further aspect of the present invention: Support seats are respectively arranged at both ends of the rotating shaft. Through holes are provided on both support seats. Both ends of the rotating shaft are respectively rotatably passed through the through holes.

[0013] In a further aspect of the present invention: Bearings are installed in the through holes of the support seats. The outer rings of the two bearings are respectively fixedly connected to the inner walls of the through holes, and the inner rings are respectively fixedly sleeved on both ends of the rotating shaft.

Therefore, even when winding a long-distance wire rope, it can be ensured that the winding point position of the wire rope does not move, and the rope is ensured to be in its original position.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative work shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-2, the present utility model discloses a winding drive device for a rope, which includes two support seats 7 fixedly arranged in parallel. Through holes are provided on both of the two support seats 7, and bearings are installed in the through holes. The inner wall of the through hole is fixedly connected to the outer ring of the bearing, and the axes of the bearings on the two support seats 7 are collinear; a rotating shaft 1 is arranged between the two support seats 7. The two ends of the rotating shaft 1 are respectively fixedly inserted into the inner rings of the bearings of the two support seats 7, and one end thereof is connected to a driving mechanism after passing through the bearing. The driving mechanism is used to drive the rotating shaft 1 to rotate.

[0027] It should be noted that both of the two support seats 7 are fixedly installed, and their installation positions are selected according to the actual situation. In most cases, they are installed on the same plane. For example, they can be installed on the same beam at the required position. In a few cases, they can also be installed on different planes, but it is necessary to ensure that the axes of the bearings in the two support seats 7 are collinear to ensure that the two ends of the rotating shaft 1 are inserted into the two bearings.

[0028] There is no limitation on the specific structure and type of the driving mechanism, as long as it can meet the requirement of driving the rotating shaft 1 to rotate. For example, in the embodiment of the utility model, the driving mechanism is composed of a driven gear 8 and a rotary driving mechanism. Among them, the driven gear 8 is fixedly connected to one end of the rotating shaft 1, that is, this end of the rotating shaft 1 extends to the outside of the bearing after passing through the bearing and is fixedly connected to the driven gear 8. The rotary driving mechanism is used to drive the driven gear 8 to rotate. There is no limitation on its specific structure, as long as it can meet the requirement of driving the driven gear 8 to rotate. For example, in the embodiment of the present utility model, the rotary driving mechanism can be composed of a motor and a driving gear. The motor is fixedly installed beside the driven gear 8, and its output shaft is fixedly connected to the driving gear. The driving gear meshes with the driven gear 8. When the motor starts to drive the driving gear to rotate, the driving gear will drive the rotating shaft 1 to rotate through the driven gear 8.

[0029] Axial key grooves are provided on the surface of the rotating shaft 1. A winding drum 2 and a threaded pipe 3 are sleeved on the rotating shaft 1. Axial splines that are keyed and matched with the axial key grooves of the rotating shaft 1 are provided on the central hole walls of the winding drum 2 and the threaded pipe 3, so that they are keyed and sleeved on the rotating shaft 1. And one end of the winding drum 2 close to the threaded pipe 3 is fixedly connected and combined into an integral body. It only slides along the axial direction on the rotating shaft 1 and cannot rotate around the rotating shaft 1.

[0030] An installation seat 5 is also fixedly installed on the plane where the two support seats 7 are installed. A through hole is provided on the installation seat 5. A threaded seat 4 is fixedly installed on one side of the installation seat 5. The threaded seat 4 is fixed on the installation seat 5 through a connecting member 6. The through hole of the threaded seat 4 communicates with and corresponds to the through hole of the installation seat 5. The threaded pipe 3 is inserted therein. External threads are provided on the surface of the threaded pipe 3, and internal threads matching the threaded pipe 3 are provided in the through hole of the threaded seat 4. A threaded fit is formed between the two, that is, the threaded pipe 3 can rotate in the threaded seat 4 by threads, and thus move its own distance.

[0031] A rope coil is provided on the winding drum 2. By rotating, the wire rope is wound or unwound. During the winding process of the wire rope, the driving mechanism drives the rotating shaft 1 to rotate, and the rotating shaft 1 drives the winding drum 2 and the threaded pipe 3 to rotate together, so that the wire rope is wound on the winding drum 2. At the same time, when the threaded pipe 3 rotates, it rotates in the threaded seat 4, so that the integral structure of the threaded pipe 3 and the winding drum 2 undergoes a displacement along the rotating shaft 1. Then, when the wire rope is wound around the winding drum 2 for one circle, the winding drum 2 moves a small distance along the rotating shaft 1, so that the position of the next circle of wire rope falls beside the previous circle of wire rope, and the displacement of the wire rope remains unchanged, ensuring that the rope is in its original position.

[0032] It should be noted that the pitch of the external thread on the surface of the threaded pipe 3 should be consistent with the diameter of the wire rope, so as to ensure that when the wire rope is wound around the winding drum 2 for one circle, the moving distance of the winding drum 2 is consistent with the diameter of the wire rope, so that each circle of wire rope can be arranged next to each other in sequence, thereby improving the winding effect.

[0033] The working principle of the present utility model:

[0034] In use, a rope coil is provided on the winding drum 2. By rotating, the wire rope is wound or unwound. During the winding process of the wire rope, the driving mechanism drives the rotating shaft 1 to rotate, and the rotating shaft 1 drives the winding drum 2 and the threaded pipe 3 to rotate together, so that the wire rope is wound on the winding drum 2. At the same time, when the threaded pipe 3 rotates, it rotates in the threaded seat 4, so that the integral structure of the threaded pipe 3 and the winding drum 2 undergoes a displacement along the rotating shaft 1. Then, when the wire rope is wound around the winding drum 2 for one circle, the winding drum 2 moves a small distance along the rotating shaft 1, so that the position of the next circle of wire rope falls beside the previous circle of wire rope, and the displacement of the wire rope remains unchanged. Therefore, even when winding a long-distance wire rope, it can be ensured that the winding point position of the wire rope does not move, and the rope is in its original position.
