Description

Technical Field

[0001] This application relates to the technical field of steel strands, and in particular to a device for oiling loose strands of steel strands. Background Technology

[0002] Currently, steel strand is an important engineering material widely used in prestressed structures in bridges, buildings, and other fields. To improve the corrosion resistance and service life of steel strand, it is usually necessary to coat the surface of the steel strand with grease.

[0003] There are many ways to apply oil, including immersion, brushing, and spraying. Immersion consumes too much oil, while spraying causes severe oil splattering. Brushing is the more common method.

[0004] When applying coating to loose strands of steel strands, if the strands are stationary, multiple angles need to be changed during application to ensure even and comprehensive coverage, which is time-consuming and labor-intensive. If the strands are in transit, the application process may result in incomplete coverage. Utility Model Content

[0005] In order to uniformly and comprehensively coat the loose strands of steel strands with oil, this application provides a device for coating loose strands of steel strands with oil.

[0006] The steel strand oiling device provided in this application adopts the following technical solution: A steel strand oiling device includes a support rod and a suspension rod. The support rod is vertically positioned and its top end is fixed to one end of the suspension rod. The suspension rod is horizontally positioned and has a ring, a support ring, and an oil box on it. The centers of the support ring and the ring are collinear and both are pierced by the steel strand during transportation. The ring is rotatably connected to the support ring and rotates relative to the support ring. An oil inlet is provided on the side wall of the ring facing the support ring, and a first oil outlet is provided on the inner wall of the ring. A second oil outlet is provided on the side wall of the support ring facing the ring, and the second oil outlet coincides with the oil inlet. A sponge is detachably connected to the inner wall of the ring for sliding contact with the outer wall of the steel strand during transportation. The oil box and the support ring are both fixed to the suspension rod. The support ring is hollow inside, and the oil outlet end of the oil box is connected to the inside of the support ring.

[0007] By adopting the above technical solution, the grease in the oil box can flow into the hollow support ring. When the ring rotates until the oil inlet and the second oil outlet coincide, the grease can enter the ring and soak the sponge on the inner wall. During transport, the loose strands of steel strand slide against the sponge. With the rotation of the ring, the sponge can coat the loose strands of steel strand with oil from all angles, ensuring uniform oiling and eliminating the need for additional machine stops to adjust the orientation. Furthermore, by adapting to the preferred transport conditions of the loose strands of steel strand, the oiling is more comprehensive, solving the problem of incomplete coating during transport.

[0008] Optionally, two rings are provided and symmetrically distributed on both sides of the support ring.

[0009] By adopting the above technical solution, the two rings apply oil from both sides of the strand of steel wire, which further expands the oiling coverage area, avoids the local omissions that may occur when applying oil with a single ring, and improves the overall oiling effect.

[0010] Optionally, a gear ring is fixed on the circumferential outer wall of the ring, a motor is fixed on the support rod, and a gear set is provided between the motor and the gear ring for the motor to drive the two rings to rotate simultaneously.

[0011] By adopting the above technical solution, the motor can synchronously drive the two rings to rotate through the gear set, eliminating the need for manual operation. This not only saves labor costs but also ensures that the two rings rotate at the same speed, guaranteeing uniform oiling on both sides and improving the automation level and oiling stability of the device.

[0012] Optionally, a collection box is provided next to the support rod, located directly below the ring, with an open top and a filter screen inside.

[0013] By adopting the above technical solution, excess grease dripping during the oiling process can fall into the collection box, and the filter screen can filter out impurities in the grease, making it convenient for subsequent recycling of the grease, reducing grease waste and lowering the cost of oiling operations.

[0014] Optionally, the top of the filter screen is covered with cushioning cotton, which has water absorption and permeability.

[0015] By adopting the above technical solution, the buffer cotton can buffer the dripping grease, preventing the grease from directly impacting the filter screen and causing splashing. At the same time, its water permeability can ensure that the grease can smoothly penetrate into the filter screen, and it can also adsorb some impurities, improving the initial filtration effect of grease.

[0016] Optionally, a reflux pump is fixed next to the support rod, with one end of the reflux pump connected to the inside of the collection box and the other end connected to the inside of the oil box.

[0017] By adopting the above technical solution, the reflux pump can transport the filtered grease in the collection box back to the oil box, forming a grease recycling system, further reducing grease consumption, reducing resource waste, and meeting the requirements of energy conservation and environmental protection.

[0018] Optionally, a shell is fixed to the outer wall of the sponge, and a latch is provided between the shell and the side wall of the ring, with the shell inserted into the ring.

[0019] By adopting the above technical solution, when the sponge is worn or contaminated, the outer shell can be separated from the ring by unlocking the latch, and a new sponge can be quickly replaced. The operation is convenient, without the need to disassemble the entire ring, saving maintenance time and ensuring the continuity of the oiling operation.

[0020] Optionally, the support rod is a telescopic rod.

[0021] By adopting the above technical solution, the telescopic length of the support rod can be adjusted according to the transportation height of the strands of steel strand, thereby changing the height of the ring and the support ring, making the device suitable for steel strand transportation scenarios at different heights, and improving the versatility and flexibility of the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By coordinating the rotation of the ring with the transport state of the loose strands of the steel strand, dynamic oiling is achieved at all angles. At the same time, the precise oil control is achieved by coordinating the holes of the support ring and the ring. This solves the problem of incomplete oiling during transportation and avoids the problems of grease waste and splashing caused by immersion and spraying methods. 2. Combining the detachable sponge design with the grease recycling system not only reduces the difficulty of equipment maintenance and operating costs, but also reduces resource waste, taking into account both practicality and energy conservation and environmental protection; 3. The combination of the telescopic pole structure and the double-ring symmetrical layout allows the device to be adapted to steel strand transportation scenarios of different heights, expands the oiling coverage area, and improves the versatility and oiling stability of the device.

[0025] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0026] This application discloses a steel strand oiling device to solve the problems of incomplete oiling of steel strands during transportation, time-consuming and laborious oiling when stationary, and serious grease waste in traditional oiling methods, thereby achieving uniform, efficient and energy-saving oiling operations.

[0027] refer to Figure 1A steel strand oiling device includes a support rod 1 and a suspension rod 2. The support rod 1 is vertically arranged, and its top end is fixedly connected to one end of the suspension rod 2. The suspension rod 2 extends horizontally, forming an L-shaped support structure. The support rod 1 is a telescopic rod, specifically employing a structure of multiple nested sleeves and locking bolts. By adjusting the nesting length of the sleeves and tightening the bolts, the overall height of the support rod 1 can be changed, thus adapting to different heights of steel strand transportation scenarios and improving the device's versatility.

[0028] refer to Figure 1 and Figure 2 A support ring 3 and an oil box 5 are fixedly installed on the suspension rod 2. Two circular rings 4 are provided on the support ring 3, with the support ring 3 located between the two circular rings 4. The centers of the support ring 3 and the two circular rings 4 are collinear, and this collinear axis is consistent with the transportation direction of the loose strands of the steel strand, ensuring that the loose strands of the steel strand can pass through the support ring 3 and the two circular rings 4 during transportation. Both the support ring 3 and the circular rings 4 have hollow interiors. The oil outlet of the oil box 5 is connected to the interior of the support ring 3 through a conduit. The grease stored in the oil box 5 can flow into the hollow cavity of the support ring 3 through the conduit. Simultaneously, a valve can be added to the oil box 5 to control the rate at which the grease flows into the support ring 3, preventing excessive grease accumulation.

[0029] refer to Figure 1 and Figure 2 Two circular rings 4 are rotatably connected to the two side walls of the support ring 3 respectively. The circular rings 4 can rotate around their own center relative to the support ring 3. Multiple oil inlet holes 41 are provided on the side wall of the circular ring 4 facing the support ring 3. A second oil outlet hole 31 is provided on the side wall of the support ring 3 facing the circular ring 4, which matches the number of oil inlet holes 41. When the circular ring 4 rotates, the oil inlet holes 41 and the second oil outlet hole 31 will periodically overlap. At this time, the grease in the support ring 3 can flow into the interior of the circular ring 4 through the overlapping holes. Multiple first oil outlet holes 42 are provided on the inner wall of the ring 4. Grease flowing into the ring 4 can soak the sponge 6 installed on the inner wall of the ring 4 through the first oil outlet holes 42. A shell 61 is fixed on the outer circumferential wall of the sponge 6. The shell 61 is adapted to the inner wall of the ring 4 and is inserted into the ring 4. A latch 7 is provided between the shell 61 and the side wall of the ring 4. The latch 7 can adopt an elastic snap-fit ​​structure. The sponge 6 and the ring 4 can be quickly disassembled and installed through the latch 7. The shell 61 itself has a slotted hole, which will not affect the oil outlet path from the ring 4 to the sponge 6. When the sponge 6 is worn or contaminated, resulting in a decrease in the oiling effect, it is not necessary to disassemble the entire ring 4. Only the latch 7 needs to be unlocked to replace the shell 61 and the sponge 6, ensuring the continuity of the oiling operation.

[0030] refer to Figure 1 and Figure 2A motor 8 is fixedly installed on the support rod 1 near the suspension rod 2. Gear rings 43 are fixedly fitted onto the outer circumferential walls of both rings 4. A gear set 9 is provided between the motor 8 and the two gear rings 43. The gear set 9 includes two driven gears 91 and one transmission gear 92. The transmission gear 92 is fixedly connected to the rotating end of the motor 8. The two driven gears 91 mesh with the transmission gear 92, and the two driven gears 91 mesh with the gear rings 43 on the two rings 4. After the motor 8 is started, the output shaft of the motor 8 drives the transmission gear 92 to drive the two driven gears 91 to rotate synchronously, thereby driving the two gear rings 43 and the two rings 4 to rotate synchronously. The rotation speed of the two rings 4 is the same, ensuring that the oiling uniformity on both sides is the same. No manual operation is required, improving the automation level and oiling stability of the device.

[0031] refer to Figure 1 and Figure 3 A collection box 10 is installed next to the support rod 1, located directly below the two rings 4. Its top is open to collect excess grease dripping from the sponge 6 or the loose strands of the steel strand during the oiling process. Inside the collection box 10, a filter screen 11 is horizontally installed. The filter screen 11 can be made of metal mesh or a polymer filter membrane to filter impurities in the dripping grease, such as dust and debris from the surface of the steel strand. A cushioning cotton 12 is laid on top of the filter screen 11. The cushioning cotton 12 is made of a water-absorbing and permeable polymer sponge material. When grease drips, the cushioning cotton 12 slows down the impact speed of the grease, preventing it from directly impacting the filter screen 11 and causing splashing. Simultaneously, the cushioning cotton 12 can absorb some fine impurities, performing preliminary filtration of the grease and improving the filtration effect of the subsequent filter screen 11.

[0032] refer to Figure 1 and Figure 3 A reflux pump 13 is also fixedly installed on the support rod 1. The inlet of the reflux pump 13 is connected to the inside of the collection box 10 through a conduit (the conduit inlet is located below the filter screen 11 to ensure that the filtered grease is drawn in), and the outlet of the reflux pump 13 is connected to the inside of the oil box 5 through a conduit. After the reflux pump 13 is started, the filtered grease in the collection box 10 can be pumped into the oil box 5, forming a grease recycling system, reducing grease consumption, lowering operating costs, and meeting the requirements of energy conservation and environmental protection.

[0033] The implementation principle of this application embodiment is as follows: Before use, adjust the extension length of the support rod 1 according to the transport height of the steel strand, so that the collinear axis of the center of the support ring 3 and the circular ring 4 is aligned with the transport path of the steel strand; pass one end of the steel strand through the support ring 3 and the two circular rings 4, ensuring that the outer wall of the steel strand slides against the sponge 6 on the inner wall of the two circular rings 4. Start the motor 8 and the return pump 13, and open the valve of the oil box 5. The grease in the oil box 5 flows into the hollow cavity of the support ring 3 through the conduit; the motor 8 drives the two circular rings 4 to rotate synchronously. When the oil inlet 41 of the circular ring 4 coincides with the second oil outlet 31 of the support ring 3, the grease flows into the circular ring 4 and wets the sponge 6 through the first oil outlet 42; the steel strand moves along the transport direction and slides against the rotating sponge 6. The sponge 6 coats the outer wall of the steel strand with oil from all angles, achieving a uniform and comprehensive oiling effect. During the oiling process, excess oil drips into the collection box 10, and after preliminary filtration by the buffer cotton 12 and fine filtration by the filter screen 11, it is pumped back to the oil box 5 by the return pump 13 for recycling. When the sponge 6 needs to be replaced, the device is turned off and the lock 7 is unlocked. The old sponge 6 and the outer shell 61 are taken out, and after replacing the new sponge 6 and the outer shell 61, they are locked again.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
