Description

Technical Field

[0001] This utility model relates to the field of steel rope anti-loosening, and in particular to a steel rope anti-loosening device. Background Technology

[0002] In coking production, a certain amount of residual coal is carried out during the leveling process of the coke pusher. This residual coal is collected in the residual coal hopper of the coke pusher. After the residual coal hopper is full, it is placed into the lower hopper of the single-bucket elevator, and then transported to the upper hopper by the single-bucket trolley, and finally loaded back into the coal car for reuse. The movement of the single-bucket trolley is achieved by a motor driving a reducer drum. The drum and the single-bucket trolley are connected by a steel cable. During the descent of the single-bucket trolley, if jamming or lower limit failure occurs, the trolley will stop moving while the motor continues to rotate. This will eventually cause the steel cable to loosen and become tangled, and in severe cases, it may even break, causing the single-bucket trolley to fall from a height, resulting in an accident that causes great inconvenience to production. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a steel rope anti-loosening device, which aims to solve the problem of steel rope loosening in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a steel rope anti-loosening device, comprising a platform, a steel rope roller fixedly connected to the top of the platform, an upper fixed pulley and a lower fixed pulley fixedly connected to the outer wall of the platform, a steel rope wound around the outer wall of the steel rope roller and the outer walls of the upper and lower fixed pulleys, a support base fixedly connected to the outer wall of the platform, a steel rope anti-loosening mechanism provided on the top of the support base, the steel rope anti-loosening mechanism comprising a limiting bracket, the bottom of the limiting bracket fixedly connected to the top of the support base, a limiting roller slidably connected to the outer wall of the limiting bracket, the bottom surface of the limiting roller contacting the top surface of the steel rope, and a sensor fixedly connected to the outer wall of the limiting roller.

[0005] As a further description of the above technical solution: an auxiliary mechanism is provided above the platform, the auxiliary mechanism includes a rotating shaft, the bottom end of the rotating shaft is rotatably connected to the outer wall of the platform, and a chuck is fixedly connected to the outer wall of the rotating shaft.

[0006] As a further description of the above technical solution: a half gear is fixedly connected to the outer wall of the rotating shaft, and a sliding tooth plate is meshed with the outer wall of the half gear, with the bottom of the sliding tooth plate slidably connected to the outer wall of the platform.

[0007] As a further description of the above technical solution: a hinge plate is hinged to the outer wall of the sliding tooth plate, and a movable plate is hinged to the side of the hinge plate away from the sliding tooth plate, and the bottom of the movable plate is slidably connected to the outer wall of the platform.

[0008] As a further description of the above technical solution: the outer wall of the platform is provided with a first limiting groove and a second limiting groove, the outer wall of the sliding tooth plate is slidably connected to the inner wall of the first limiting groove, and the outer wall of the movable plate is slidably connected to the inner wall of the second limiting groove.

[0009] As a further description of the above technical solution: a locking mechanism is provided above the platform. The locking mechanism includes two limiting shafts. The bottom ends of the two limiting shafts are rotatably connected to the outer wall of the platform, and friction plates are fixedly connected to the top ends of the two limiting shafts respectively.

[0010] As a further description of the above technical solution: a connecting rod is fixedly connected to the outer wall of the movable plate.

[0011] As a further description of the above technical solution: magnetic blocks are fixedly connected to the outer walls of the two friction plates that are close to each other, and the two magnetic blocks are magnetically connected.

[0012] This utility model has the following beneficial effects:

[0013] 1. After the addition of the anti-slack steel rope device to the single-bucket coal trolley, if the steel rope becomes loose during the descent of the single-bucket trolley, the motor can stop in time and the brake will tighten at the same time, preventing the steel rope from loosening further and avoiding accidents such as steel rope breakage and trolley falling from a height, making production smoother and increasing coke production.

[0014] 2. In this utility model, the limiting roller slides on the limiting bracket and contacts the steel rope. The sensor on its outer wall can monitor the tension of the steel rope in real time. When the steel rope becomes loose, the sensor triggers a signal, and the movable plate in the auxiliary mechanism drives the hinge plate and the sliding tooth plate to rotate, thereby driving the half gear and the rotating shaft to rotate, which in turn drives the chuck to tighten the steel rope. This achieves timely detection and active adjustment of the loose steel rope, effectively preventing the steel rope from becoming too loose.

[0015] 3. In this utility model, two friction plates rotate through a limiting shaft, and their opposing magnetic blocks are magnetically connected. When the auxiliary mechanism is in operation, the movable plate drives the connecting rod to separate the magnetic blocks, so that the friction plates adhere to the outer wall of the half gear to generate friction braking, preventing the half gear from rotating in the opposite direction, enhancing the stability of the steel rope tension state, and improving the overall anti-loosening reliability of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a steel rope anti-loosening device, comprising a platform 1, a steel rope drum 2 fixedly connected to the top of the platform 1 for unwinding or winding a steel rope 3, the other end of the steel rope 3 being connected to a single-bucket trolley, an upper fixed pulley 4 and a lower fixed pulley 5 fixedly connected to the outer wall of the platform 1, and a steel rope 3 wound around the outer wall of the steel rope drum 2 and the outer walls of the upper and lower fixed pulleys 4 and 5, respectively, and a support base 6 fixedly connected to the outer wall of the platform 1, with a steel rope anti-loosening mechanism 7 provided on the top of the support base 6 for bearing... The steel rope anti-loosening mechanism 7 includes a limiting bracket 703. The bottom of the limiting bracket 703 is fixedly connected to the top of the support base 6. A limiting roller 701 is slidably connected to the outer wall of the limiting bracket 703. The limiting roller 701 can rotate and its height can be adjusted on the limiting bracket 703. The bottom surface of the limiting roller 701 is in contact with the top surface of the steel rope 3. A sensor 702 is fixedly connected to the outer wall of the limiting roller 701. The sensor 702 is used to control the height adjustment of the limiting roller 701.

[0024] Reference Figure 1 - Figure 3An auxiliary mechanism 8 is provided above platform 1. The auxiliary mechanism 8 includes a rotating shaft 801, the bottom end of which is rotatably connected to the outer wall of platform 1. The outer wall of the rotating shaft 801 contacts the outer wall of the steel rope 3. A chuck 808 is fixedly connected to the outer wall of the rotating shaft 801, and a half gear 802 is fixedly connected to the outer wall of the rotating shaft 801. The half gear 802 is driven to rotate, which in turn drives the rotating shaft 801 to rotate. After the chuck 808 rotates, the steel rope 3 is drawn inward, providing friction. A sliding tooth plate 803 is meshed with the outer wall of the half gear 802. The bottom of the sliding tooth plate 803 is slidably connected to the outer wall of platform 1. The displacement of the sliding tooth plate 803 will drive the meshing half gear 802 to rotate. A hinge plate 805 is hinged to the sliding tooth plate 803. The displacement of the sliding tooth plate 803 will cause the hinge plate 805 to tilt. A movable plate 806 is hinged to the side of the hinge plate 805 away from the sliding tooth plate 803. Through an external hydraulic device, the movable plate 806 can be controlled to move, thereby driving the hinge plate 805 to move. The bottom of the movable plate 806 is slidably connected to the outer wall of the platform 1. The outer wall of the platform 1 is provided with a first limiting groove 804 and a second limiting groove 807. The outer wall of the sliding tooth plate 803 is slidably connected to the inner wall of the first limiting groove 804. The first limiting groove 804 provides a sliding limiting effect for the sliding tooth plate 803. The outer wall of the movable plate 806 is slidably connected to the inner wall of the second limiting groove 807. The second limiting groove 807 provides a sliding limiting effect for the movable plate 806.

[0025] Reference Figure 2 - Figure 4 A locking mechanism 9 is provided above the platform 1. The locking mechanism 9 includes two limiting shafts 901. The bottom ends of the two limiting shafts 901 are rotatably connected to the outer wall of the platform 1. The top ends of the two limiting shafts 901 are respectively fixedly connected to friction plates 902. The friction plates 902 can rotate around the limiting shafts 901. A connecting rod 904 is fixedly connected to the outer wall of the movable plate 806. Magnetic blocks 903 are fixedly connected to the outer walls of the two friction plates 902 that are close to each other. The two magnetic blocks 903 are magnetically connected. After the movable plate 806 is driven to move, it will drive the connecting rod 904 to move synchronously, which will apply pressure to the magnetic attraction of the two friction plates 902, forcing the two friction plates 902 to no longer be in the magnetic attraction state. After the half gear 802 is driven to rotate, its non-gear arc surface faces the friction plate 902. The friction plate 902 that is released from magnetic attraction will rub against the outer wall surface of the half gear 802 to generate friction force, preventing the half gear 802 from slightly reversing.

[0026] Working principle: When the steel cable 3 is in normal working tension, the tension of the steel cable 3 supports the limiting roller 701 upward, keeping it in a high position within the slide of the limiting bracket 703. At this time, the sensor 702 fixed to the outer wall of the limiting roller 701 does not trigger a signal. Once the steel cable 3 loosens and sags due to equipment failure, the supporting force on the limiting roller 701 weakens, and the limiting roller 701 slides downward along the slide of the limiting bracket 703 under the action of gravity. When the displacement reaches the set threshold, the sensor 702 is triggered and sends a signal. At this time, the external hydraulic system is started, driving the movable plate 806 to open on the outer wall of the platform 1. The sliding plate 803 moves horizontally within the second limiting groove 807. The movement of the movable plate 806 is transmitted through the hinge plate 805, which is hinged to it, pushing the sliding tooth plate 803 to slide horizontally along the trajectory defined by the first limiting groove 804 on the outer wall of the platform 1. The movement of the sliding tooth plate 803 acts on the half gear 802 that meshes with it, forcing the half gear 802 to rotate around its fixed rotating shaft 801. Since the rotating shaft 801 is fixedly connected to the chuck 808, the rotation of the half gear 802 synchronously drives the rotating shaft 801 and the chuck 808 to rotate. The rotational movement of the chuck 808 winds and tightens the slack steel rope 3, realizing the active tensioning of the steel rope 3. This prevents further loosening; simultaneously, the connecting rod 904, fixedly connected to the outer wall of the movable plate 806, moves synchronously with the movable plate 806. The end of the connecting rod 904 acts on the junction of the two magnetic blocks 903 of the locking mechanism 9, applying external force to force the two magnetic blocks 903, which were originally tightly connected by magnetic attraction, to separate from each other. After the magnetic connection is released, the two friction plates 902 lose their magnetic constraint and, under the action of gravity or the linkage of the mechanism, rotate inward around the limiting shaft 901 at their bottom. This causes the wear-resistant layer on the inner side of the two friction plates 902 to be tightly pressed onto the smooth outer wall surface of the toothless half gear 802, producing significant slippage. Dynamic friction; this frictional resistance forms an instantaneous mechanical brake on the half gear 802, effectively preventing the half gear 802 from rotating in the opposite direction under the tension of the steel rope 3 or the rebound force of the mechanism, ensuring a stable tension state; after the fault is cleared and the steel rope 3 is restored to a taut state, the hydraulic system reverses the drive of the movable plate 806 to reset, and the sliding plate 803, hinge plate 805, half gear 802 and chuck 808 return to their respective positions. At the same time, the connecting rod 904 releases the pressure on the magnetic block 903, and the two magnetic blocks 903 automatically re-adhere and close under the action of magnetic force, driving the friction plate 902 to disengage from the half gear 802, and the device returns to its initial standby state.
