Description

Technical Field

[0001] This utility model relates to the field of winch technology, and in particular to a winch wire rope anti-breakage protection device. Background Technology

[0002] A winch is a mechanical device that uses a drum to wind steel wire rope or chain to lift, pull, or move heavy objects. It mainly consists of a motor, reducer, drum braking system, and control system. It is widely used in mines, ports, construction sites, and other places. The electric motor drives the drum to rotate, causing the steel wire rope or chain to wind or release, thereby realizing the vertical lifting or horizontal pulling of heavy objects. Winches are characterized by their compact structure, simple operation, and strong load-bearing capacity, and are an indispensable and important lifting and transportation equipment in modern industry.

[0003] The existing winches lack a lubrication system for the wire rope, causing severe friction between the wire rope and components such as pulleys and drums during operation. This easily leads to scratches and wear on the surface. After long-term use, the grease inside the wire rope gradually depletes, and the metal wires become fatigued due to dry friction, ultimately resulting in a significantly increased risk of breakage. This not only affects the safety and service life of the equipment but also requires frequent oiling and maintenance by staff, increasing maintenance costs and workload. Especially under harsh working conditions, the lack of continuous lubrication makes the wire rope more prone to rust and deformation, further shortening its replacement cycle.

[0004] Therefore, in view of the problem that the existing winches lack a lubrication structure for the wire rope during use, making them prone to breakage after long-term use and requiring periodic maintenance by staff, a winch wire rope anti-breakage protection device can be designed. Utility Model Content

[0005] In order to overcome the problem that existing winches lack a lubrication structure for the wire rope during use, making them prone to breakage after long-term use and requiring periodic maintenance by staff.

[0006] The technical solution of this utility model is as follows: a winch wire rope anti-breakage protection device, including a support and a nozzle. Two supports are symmetrically arranged front and rear. Bearing seats are installed on the outer sides of both supports, and a rotating shaft connects the two bearing seats. A steel cable is wound around the outer side of the rotating shaft. A transmission module is installed on the rear surface of the rear support, including a motor and a reducer. A lead screw is rotatably connected between the two supports. A drive motor is installed on the front surface of the front support, and the output end of the drive motor is fixedly connected to the front end of the lead screw. The drive motor drives the lead screw to rotate. A movable seat is threaded through the outer side of the lead screw. An oil can is installed on the top of the movable seat, and a nozzle is installed on the top of the oil can. A limit rod is provided between the two supports, and a limit block is slidably connected through the outer side of the limit rod. Two connecting rods are fixedly fixed on the top of the limit block, and the tops of the connecting rods are fixedly connected to the bottom of the movable seat. A monitoring mechanism is provided on the right side of both supports to monitor the tension of the steel cable. A limit mechanism is also provided on the right side of both supports to limit the movement of the steel cable.

[0007] Preferably, by setting a drive motor, both the drive motor and the nozzle are controlled by an external controller. After the drive motor starts, its output end will drive the lead screw to rotate. When the lead screw rotates, it drives the moving seat that is threaded with it to move back and forth. When the moving seat moves, it drives the connecting rod and the oil can to move synchronously. When the connecting rod moves, it drives the limit block to slide outside the limit rod, thereby limiting the moving seat. When the oil can moves, it drives the nozzle to move synchronously. The pump inside the nozzle can spray the lubricating oil inside the oil can onto the surface of the steel cable, thereby achieving the lubrication function, reducing steel cable wear, and reducing the frequency of maintenance by workers. This solves the problem that existing winches lack a lubrication structure for the wire rope during use, making them prone to breakage after long-term use and requiring periodic maintenance by workers.

[0008] Preferably, the monitoring mechanism includes a fixing component and a sensing component. The fixing component is used to install the sensing component, and the sensing component is used to monitor the tension of the steel cable during winding and unwinding.

[0009] Preferably, the fixing assembly includes a support rod and a fixing platform; the support rod is fixed to the opposite sides of the two supports by bolts, and the fixing platform is fixed between the two support rods.

[0010] Preferably, the sensing component includes a pulley-type tension sensor; the pulley-type tension sensor is mounted on the top of the mounting platform by screws and is electrically connected to an external alarm.

[0011] Preferably, the limiting mechanism includes a positioning component and a clamping component, wherein the positioning component is used to install the clamping component and the clamping component is used to level the steel cable.

[0012] Preferably, the positioning assembly includes a fixed shaft, sleeves, and a crank arm; the fixed shaft is fixed between the two supports, and two sleeves are installed on the outside of the fixed shaft via torsion springs, with a crank arm provided on the outside of each sleeve.

[0013] Preferably, the clamping assembly includes a roller and a positioning ring; a roller is provided between the two crank arms, and positioning rings are installed at both ends of the roller, and the roller is rotatably connected to the crank arms through the positioning rings.

[0014] The beneficial effects of this utility model are:

[0015] By installing oil cans and spray nozzles, lubricating oil can be sprayed onto the surface of the wire rope regularly and evenly, significantly improving maintenance efficiency, reducing the workload of workers, eliminating the need for frequent maintenance, reducing labor intensity, and the continuous oil film coverage effectively prevents the wire rope from wearing due to dry friction, while also inhibiting corrosion, greatly reducing the risk of breakage, and ensuring that the wire rope can maintain good operating condition even in harsh environments such as high temperature and humidity. This not only extends the service life of the wire rope, but also improves the safety and reliability of the equipment, and the overall maintenance cost is also significantly optimized.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a winch wire rope anti-breakage protection device, including a support 1 and a nozzle 10. Two supports 1 are symmetrically arranged, one in front and one behind. Bearing seats 2 are installed on the outer sides of both supports 1, and a rotating shaft 3 connects the two bearing seats 2. A steel cable 4 is wound around the outer side of the rotating shaft 3. A transmission module 5 is installed on the rear surface of the rear support 1, including a motor and a reducer. A lead screw 6 is rotatably connected between the two supports 1. A drive motor 7 is installed on the front surface of the front support 1, and the output end of the drive motor 7 is fixedly connected to the front end of the lead screw 6. The drive motor 7 drives the lead screw 6 to rotate. A movable seat 8 is threadedly connected to the outer side of the lead screw 6. An oil can 9 is installed on the top of the movable seat 8, and a nozzle 10 is installed on the top of the oil can 9. A limit rod 11 is provided between the two supports 1, and a limit block 12 is slidably connected to the outer side of the limit rod 11. Two connecting rods 13 are fixedly fixed to the top of the limit block 12, and the top of the connecting rods 13 are fixedly connected to the bottom of the movable seat 8. Next, a monitoring mechanism is set on the right side of the two supports 1 to monitor the tension of the steel cable 4. A limit mechanism is also set on the right side of the two supports 1 to limit the steel cable 4. A drive motor 7 is set and started under the command of an external controller. Its output shaft drives the lead screw 6 to rotate. The rotation of the lead screw 6 causes the moving seat 8, which forms a threaded pair with it, to produce a linear displacement along the axial direction. During the movement, the moving seat 8 synchronously drives the connecting rod 13 and the oil can 9 to perform translational movement. The movement of the connecting rod 13 is guided by the sliding of the limit block 12 at its end on the limit rod 11. This structure can effectively constrain the movement trajectory of the moving seat 8 and ensure the stability of operation. The displacement of the oil can 9 directly drives the nozzle 10 to move synchronously. During operation, the pump built into the nozzle 10 pressurizes and delivers the lubricating oil stored in the oil can 9. The lubricating medium is evenly sprayed onto the surface of the steel cable 4 through the nozzle, which can significantly reduce the friction loss of the steel cable 4 during operation and reduce the frequency of maintenance operations.

[0024] Please see Figure 1 and Figure 4In this embodiment, the monitoring mechanism includes a fixing component and a sensing component. The fixing component is used to install the sensing component, which is used to monitor the tension of the steel cable 4 during winding and unwinding. The fixing component includes a support rod 141 and a fixing platform 142. The support rod 141 is fixed to the opposite sides of the two supports 1 by bolts, and the fixing platform 142 is fixed between the two support rods 141. The support rod 141 is used to install and position the fixing platform 142, so that the fixing platform 142 is in a suitable working position. The sensing component includes a pulley-type tension sensor 143. The pulley-type tension sensor 143 is installed on the top of the fixing platform 142 by screws. The pulley-type tension sensor 143 is electrically connected to an external alarm. By setting the pulley-type tension sensor 143 of model SHL-360, the tension of the steel cable 4 during winding and unwinding can be detected during operation. If the tension is not within the threshold range, the external controller will control the external alarm to sound an alarm.

[0025] Please see Figure 1 and Figure 5 In this embodiment, the limiting mechanism includes a positioning component and a clamping component. The positioning component is used to install the clamping component, and the clamping component is used to level the steel cable 4. The positioning component includes a fixed shaft 151, a sleeve 152, and a crank arm 153. A fixed shaft 151 is fixed between the two supports 1. Two sleeves 152 are installed on the outside of the fixed shaft 151 via torsion springs. A crank arm 153 is provided on the outside of each of the two sleeves 152. The fixed shaft 151 is used to install the sleeves 152. The torsion of the torsion spring causes the crank arm 153 to always deflect toward the steel cable 4. The clamping assembly includes a roller 154 and a positioning ring 155. A roller 154 is provided between the two crank arms 153. Positioning rings 155 are installed at both ends of the roller 154. The roller 154 is rotatably connected to the crank arm 153 through the positioning rings 155. By setting the roller 154, under the drive of the crank arm 153, the roller 154 will always keep in contact with the steel cable 4, thereby positioning the steel cable 4 when it is wound up and unwound.

[0026] During operation, the drive motor 7 drives the lead screw 6 to rotate, causing the movable seat 8, which is threaded onto the lead screw 6, to move back and forth. The oil can 9 and the nozzle 10 on the top of the movable seat 8 move accordingly. The nozzle 10 sprays the lubricating oil in the oil can 9 onto the surface of the steel cable 4 for lubrication and to reduce wear. The movable seat 8 drives the limit block 12 to slide on the limit rod 11 through the connecting rod 13 to limit the movement. The pulley-type tension sensor 143 on the support rod 141 and the fixed platform 142 monitors the tension of the steel cable 4. If the tension is not within the threshold range, the external alarm is triggered by the external controller. The sleeve 152 and the crank arm 153 on the fixed shaft 151 keep the roller 154 pressed against the steel cable 4 under the action of the torsion spring. The roller 154 is rotatably connected to the crank arm 153 through the positioning ring 155 to level the steel cable 4 and prevent it from shifting.

[0027] Through the above steps, by setting up the drive motor 7, when the drive motor 7 starts, its output shaft drives the lead screw 6 to rotate. Since the moving seat 8 and the lead screw 6 are threaded together, the rotation of the lead screw 6 will push the moving seat 8 to move axially. The movement of the moving seat 8 causes the oil can 9 and the nozzle 10 to move synchronously. During the movement, the limiting block 12 on the connecting rod 13 slides along the limiting rod 11 to limit the movement range of the moving seat 8 and ensure its stable running trajectory. At the same time, the pump inside the nozzle 10 pumps out the lubricating oil in the oil can 9 and evenly coats it on the surface of the steel cable 4 in an atomized or sprayed manner to form a lubricating film layer. This can effectively reduce the friction loss of the steel cable 4 during operation, extend its service life, reduce the frequency of lubrication maintenance by the staff, and improve the overall automation level. This solves the problem that the existing winches lack a lubrication structure for the wire rope during use, which makes them prone to breakage after long-term use and requires periodic maintenance by the staff.
