Description

Technical Field

[0001] This utility model relates to the field of wire rope testing technology, specifically a crane wire rope testing device. Background Technology

[0002] Wire rope is a helical bundle of steel wires twisted together according to specific rules, meeting requirements for mechanical properties and geometric dimensions. It consists of steel wires, a core, and lubricant. Wire rope is made by first twisting multiple layers of steel wires into strands, then winding a certain number of strands around the core to form a helical shape. In material handling machinery, it is used for lifting, traction, tensioning, and load bearing. Wire rope is characterized by high strength, light weight, stable operation, and resistance to sudden breakage, ensuring reliable operation. After production, wire rope undergoes strength and quality testing, followed by damage assessment.

[0003] For example, application number CN202222674476.6 discloses a crane wire rope testing device, specifically relating to the field of wire rope testing. It includes a support frame, with a testing device mounted on the upper end of the support frame. A rope-releasing device is mounted at the front end of the testing device, and a rope-retracting device is mounted at the rear end. The testing device includes a damage detector, auxiliary components, and fixing components. In this crane wire rope testing device, when the upper end of the auxiliary baffle moves, the auxiliary baffle also rotates accordingly. The rotation of the auxiliary baffle effectively prevents friction with the outer wall of the wire rope, thus avoiding damage to the outer wall or the possibility of fire due to excessive frictional heat. The auxiliary baffle also limits the wire rope's movement, effectively preventing deviation after testing and increasing the difficulty of rope retraction. The auxiliary and fixing components are easy to install and disassemble. The auxiliary baffle can be disassembled and its model replaced, further enhancing the practicality of the entire device.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of existing wire rope testing equipment having an auxiliary device at the rear end, causing the wire rope to easily deviate and rub against the testing equipment during testing, resulting in damage to the outer wall of the wire rope, the auxiliary baffle used to limit and guide the wire rope during use is fixed to the surface of the rotating sleeve. This means that the auxiliary baffle cannot be adjusted to adapt to wire ropes of different diameters, thus presenting certain limitations. Utility Model Content

It solves the problem that the auxiliary baffle is fixed to the surface of the rotating sleeve during use, which makes it unable to adapt to wire ropes of different diameters, thus having certain limitations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crane wire rope detection device, comprising a support frame, a rope winding device, a rope releasing device, a breakage detector, and an operation control panel. The rope winding device is located on the front side of the support frame, and the rope releasing device is located on the right side of the support frame. A wire rope is provided on the top of the support frame, with the front end of the wire rope wound around the surface of the rope winding device.

[0009] In a preferred embodiment of this invention, the movable component includes a movable groove, which is formed on the surface of the adjusting and limiting plate. Several movable grooves are formed and are distributed in a ring at equal intervals. A fixed shaft is fixedly connected inside the movable groove, and a movable roller is movably connected to the surface of the fixed shaft. The movable roller is movably connected to a wire rope.

[0010] As a preferred embodiment of this utility model, connecting grooves are provided on both sides of the surface of the mounting cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting an adjusting limit plate, enables the adjusting limit plate to adapt to wire ropes of different diameters. This solves the problem that when using an auxiliary baffle to limit and guide the wire rope, the auxiliary baffle is fixed to the surface of the rotating sleeve during use, which makes it unable to adapt to wire ropes of different diameters, thus having certain limitations. This utility model has the advantage of adaptability and adjustment.

[0015] 2. This utility model, by setting up a transmission component, enables the dual-output motor to drive the screw to rotate after starting.

Furthermore, by setting up a sliding component, the sliding ring inside the movable groove can reduce the friction between the wire rope and the surface of the mounting cylinder. At the same time, the use of a sealing ring can prevent foreign objects from entering the movable groove and jamming the sliding ring.

[0016] 3. By setting up movable components, this utility model can reduce the friction between the wire rope and the adjusting limit plate by setting up movable rollers on the fixed shaft surface inside the movable groove, thereby further reducing the frictional loss between the adjusting limit plate and the wire rope. Furthermore, by setting up connecting grooves and limiting strips, the cooperation between the connecting grooves and limiting strips can limit the movable cylinder, thereby ensuring the stability of the movable cylinder when it moves.

[0024] As a technical optimization of this utility model, by setting a transmission component 8, the dual-output motor 81 can drive the screw 82 to rotate after starting. After the screw 82 rotates, it can drive the screw sleeve 83 to move outward. After the screw sleeve 83 moves outward, it can drive the movable cylinder 84 to move outward. After the movable cylinder 84 moves outward, it can drive the adjusting limit plate 7 to move outward, thereby adjusting the adjusting limit plate 7.

The sealing rings 93 are movably connected to the inner wall of the sliding groove 91, and the wire rope 17 is movably connected to the sliding ring 92.

[0026] As a technical optimization of this utility model, by setting the sliding component 9, the sliding ring 92 inside the movable groove 101 can reduce the friction between the wire rope 17 and the surface of the mounting cylinder 6. At the same time, the use of the sealing ring 93 can prevent foreign objects from entering the movable groove 101 and jamming the sliding ring 92.

[0027] refer to Figure 1 and Figure 2 The movable component 10 includes a movable groove 101, which is formed on the surface of the adjusting limit plate 7. The movable groove 101 has a plurality of grooves and is distributed in a ring at equal intervals. A fixed shaft 102 is fixedly connected inside the movable groove 101. A movable roller 103 is movably connected to the surface of the fixed shaft 102. The movable roller 103 is movably connected to the wire rope 17.

[0028] As a technical optimization of this utility model, by setting the movable component 10, the movable roller 103 on the surface of the fixed shaft 102 inside the movable groove 101 can reduce the friction between the wire rope 17 and the adjusting limit plate 7, thereby further reducing the frictional loss between the adjusting limit plate 7 and the wire rope 17.

Several connecting grooves 12 are provided and are distributed in a ring at equal intervals. Limiting strips 13 are movably connected inside the connecting grooves 12 and are fixedly connected to the inner wall of the movable cylinder 84.

[0030] As a technical optimization of this utility model, by setting the connecting groove 12 and the limiting strip 13, the cooperation of the connecting groove 12 and the limiting strip 13 can limit the movement of the movable cylinder 84, thereby ensuring the stability of the movable cylinder 84 when it moves.

[0031] refer to Figure 3 The front and rear sides of the surface of the movable cylinder 84 are provided with positioning grooves 14, and the front and rear sides of both sides of the surface of the mounting cylinder 6 are fixedly connected with positioning pins 15, and the positioning grooves 14 and positioning pins 15 are movably connected.

[0032] As a technical optimization of this utility model, by setting the positioning groove 14 and the positioning pin 15, the positioning groove 14 and the positioning pin 15 can be used together to position the movable cylinder 84 and prevent the movable cylinder 84 from separating from the mounting cylinder 6.

[0033] refer to Figure 3 A reinforcing plate 16 is fixedly connected to the surface of the bracket 11.

[0034] As a technical optimization of this utility model, by setting a reinforcing plate 16, the reinforcing plate 16 can reinforce the bracket 11, thereby ensuring that the bracket 11 is more stable during use.

[0035] The working principle and usage process of this utility model are as follows: When adjusting the adjusting limit plate 7, the dual-output motor 81 inside the mounting cylinder 6 is started. After starting, the dual-output motor 81 drives the screw 82 to rotate. The rotation of the screw 82 drives the screw sleeve 83 to move outward inside the mounting cylinder 6. The screw sleeve 83 then drives the movable cylinder 84 to move forward on the surface of the mounting cylinder 6. While the movable cylinder 84 moves, it is limited by the connecting groove 12 and the limiting strip 13, making the outward movement of the movable cylinder 84 more stable. Simultaneously, the outward movement of the movable cylinder 84 drives the adjusting limit plate 7 to move forward, causing the adjusting limit plate 7 to... After the outer side moves, it can adapt to steel wire ropes 17 of different diameters. The movable roller 103 on the fixed surface of the movable groove 101 on the surface of the adjusting limit plate 7 can reduce the friction between the steel wire rope 17 and the adjusting limit plate 7, avoiding large frictional losses when the adjusting limit plate 7 limits the steel wire rope 17. The sliding ring 92 inside the sliding groove 91 can support the bottom of the steel wire rope 17, thereby reducing the friction when the steel wire rope 17 moves on the mounting cylinder 6. The sealing ring 93 can prevent foreign objects from falling into the sliding groove 91 and jamming the sliding ring 92, thus achieving the effect of adaptation and adjustment. (Multiple induction detectors are provided inside the breakage detector 4.)

[0036] In summary, this crane wire rope detection device, by setting an adjusting limit plate 7, enables the adjusting limit plate 7 to adapt to wire ropes 17 of different diameters. This solves the problem that when using an auxiliary baffle to limit and guide the wire rope, the auxiliary baffle is fixed to the surface of the rotating sleeve during use, which prevents the auxiliary baffle from being adjusted to adapt to wire ropes of different diameters, thus having certain limitations.
