Description

Technical Field

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

[0002] Wire rope is a helical bundle of steel wires that meet the requirements of mechanical properties and geometric dimensions, twisted together according to certain rules. Wire rope consists of steel wires, a rope core, and lubricant. Therefore, wire rope is suitable for traction and other purposes. Port lifting equipment uses wire rope for traction. In order to ensure the safe lifting of goods, detection devices are often used to conduct safety inspections.

[0003] For example, application number CN202222593594.4, this utility model relates to the field of wire rope detection technology, specifically a wire rope detection device for port lifting equipment, including a support frame, with motors fixedly connected to both sides inside the support frame. The advantages of this utility model are: first pulleys are fixedly connected to the output ends of two motors, and two second pulleys are rotatably connected to one side of each of the two fixed blocks. The two electric push rods shorten, causing the detector body to open, placing the two second pulleys on the wire rope, bringing the two first pulleys and two second pulleys closer together, and tightening two wing bolts to install the device on the wire rope. The two motors are energized, driving the device to move along the wire rope, facilitating the detector body's detection of the wire rope. The entire process does not require retracting the suspension beam, thus not affecting the lifting and transportation of goods by the lifting equipment, thereby easily meeting the user's needs. Furthermore, the overall structure is simple and easy for users to operate.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of the time required for detection, during which the lifting equipment is in a stopped state, affecting the lifting of cargo at the port, during the application of the equipment, only the first pulley is driven. When the wire rope is pulled, the second pulley, as the driven pulley, cannot rotate synchronously with the first pulley in a symmetrical direction, which leads to slippage. As a result, the tension on both ends of the wire rope is uneven, thus affecting the accuracy of the detection. Utility Model Content

This leads to uneven tension on both ends of the wire rope, thus affecting the accuracy of the detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire rope detection device for lifting equipment, comprising a support frame, a detection device, a motor, a first pulley, and a second pulley. The back of the detection device is fixedly connected to the top of the front side of the inner wall of the support frame.

The second pulley is located on top of the first pulley. Mounting plates are fixedly connected to both sides of the front side of the inner wall of the support frame. A first gear is movably connected to the inner side of the back of the mounting plate via a pin. The back of the first gear is fixedly connected to the front of the first pulley. A second gear is meshed with the outer side of the first gear. A transmission mechanism is fixedly connected to the front of the second gear.

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

[0014] 1. This utility model, by setting a first gear and a second gear, allows the wire rope to be clamped by the first and second pulleys after the lifting assembly drives the second pulley to descend. During testing, the motor is started, driving the first pulley to rotate, which in turn drives the first gear to rotate. Consequently, the second gear rotates in the opposite direction to the first pulley. Then, through the transmission mechanism, the second pulley finally rotates in the corresponding direction. This solves the problem that when only the first pulley is driven, the second pulley, as the driven wheel, cannot rotate synchronously with the first pulley in a symmetrical direction when the wire rope is pulled, resulting in slippage.

The rotation of the second gear is stably transmitted to the second sprocket, which in turn drives the second pulley connected to it to rotate. Finally, the first pulley and the second pulley rotate synchronously in a symmetrical direction, thus stabilizing the tension at both ends of the wire rope to be consistent.

[0016] 3. By setting up a lifting component, when the wire rope needs to be clamped by the first pulley and the second pulley, the wire rope is first placed on the first pulley, and then the electric telescopic rod is activated to drive the support block to drive the second sprocket and the second pulley to descend, so that the wire rope is successfully clamped by the first pulley and the second pulley, thereby improving the user's ease of operation.

[0021] 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.

[0022] like Figures 1 to 3 As shown, the present invention provides a wire rope detection device 2 for lifting equipment, including a support frame 1, a detection device 2, a motor 3, a first pulley 4, and a second pulley 5. The back of the detection device 2 is fixedly connected to the top of the front side of the inner wall of the support frame 1. The back of the motor 3 is fixedly connected to both sides of the rear side of the inner wall of the support frame 1. The back of the first pulley 4 is fixedly connected to the output end of the motor 3. The second pulley 5 is located on top of the first pulley 4. Mounting plates 6 are fixedly connected to both sides of the front side of the inner wall of the support frame 1. A first gear 7 is movably connected to the inner side of the back of the mounting plate 6 through a shaft pin. The back of the first gear 7 is fixedly connected to the front of the first pulley 4. A second gear 8 is meshed with the outer side of the first gear 7. A transmission mechanism 9 is fixedly connected to the front of the second gear 8. A lifting assembly 10 is provided on the front of the second pulley 5.

[0023] refer to Figure 1 and Figure 3 The transmission mechanism 9 includes a first sprocket 91, the back of the first sprocket 91 is fixedly connected to the front of the second gear 8, the front of the first sprocket 91 is movably connected to the outer side of the back of the mounting plate 6 through a shaft pin, the front of the second pulley 5 is fixedly connected to the second sprocket 92, and the back of the mounting plate 6 is provided with a chain 93, and the first sprocket 91 and the second sprocket 92 are meshed and connected through the chain 93.

[0024] As a technical optimization of this utility model, by setting up a transmission mechanism 9, when the motor 3 drives the first pulley 4 to rotate, the first gear 7 rotates, and then the second gear 8 rotates, the first sprocket 91 rotates with the second gear 8, and drives the second sprocket 92 to rotate through the chain 93, so that the rotation of the second gear 8 is stably transmitted to the second sprocket 92, which in turn drives the second pulley 5 connected to it to rotate, so that the first pulley 4 and the second pulley 5 rotate synchronously in a symmetrical direction, thus stabilizing the tension at both ends of the wire rope to be consistent.

[0025] refer to Figure 1The lifting assembly 10 includes a support block 101 and an electric telescopic rod 102. The front side of the bottom of the support block 101 is fixedly connected to the output end of the electric telescopic rod 102. The bottom of the electric telescopic rod 102 is fixedly connected to the inner side of the top of the mounting plate 6. The front of the second sprocket 92 is movably connected to the back of the support block 101 through a pin. The outer side of the support block 101 is movably connected to a tensioning mechanism 11 through a pin.

[0026] As a technical optimization of this utility model, by setting up the lifting component 10, when the wire rope needs to be clamped by the first pulley 4 and the second pulley 5, the wire rope is first placed on the first pulley 4, and then the electric telescopic rod 102 is activated to drive the support block 101 to drive the second sprocket 92 and the second pulley 5 to descend, so that the wire rope is successfully clamped by the first pulley 4 and the second pulley 5, thereby improving the user's ease of operation.

[0027] refer to Figure 2 and Figure 3 The tensioning mechanism 11 includes a connecting rod 111. The top of the inner side of the connecting rod 111 is movably connected to the outer side of the support block 101 via a pin. The bottom of the outer side of the connecting rod 111 is movably connected to a slider 112 via a pin. The bottom of the slider 112 is slidably connected to the top of the mounting plate 6. The back of the slider 112 is movably connected to a tensioning sprocket 113 via a pin. The tensioning sprocket 113 is meshed with the chain 93.

[0028] As a technical optimization of this utility model, by setting a tensioning mechanism 11, when the electric telescopic rod 102 drives the support block 101 to rise and fall, the connecting rod 111 will pull the slider 112 to move back and forth, and drive the tensioning sprocket 113 to move together. Thus, under the action of the tensioning sprocket 113, when the distance between the first sprocket 91 and the second sprocket 92 changes, the chain 93 used for transmission always maintains a suitable tension, thereby preventing the chain 93 from falling off during the process.

[0029] refer to Figure 1 A straight rod 12 is slidably connected to the inner wall of the support block 101, and the bottom of the straight rod 12 is fixedly connected to the rear side of the inner side of the top of the mounting plate 6.

[0030] As a technical optimization of this utility model, by setting a straight rod 12, when the support block 101 is raised and lowered by the electric telescopic rod 102, its inner wall slides along the straight rod 12, continuously providing support for the support block 101, thereby preventing the electric telescopic rod 102 from being damaged due to excessive force during the transmission of the first sprocket 91 and the second sprocket 92 through the chain 93.

[0031] refer to Figure 3 The inner wall of the slider 112 is slidably connected to a trapezoidal plate 13, and the bottom of the trapezoidal plate 13 is fixedly connected to the rear side of the top of the mounting plate 6.

[0032] As a technical optimization of this utility model, by setting a trapezoidal plate 13, during the process of the slider 112 being pulled by the connecting rod 111 and sliding back and forth repeatedly along the mounting plate 6, the inner wall of the slider 112 continues to slide along the trapezoidal plate 13. Thus, under the path limit of the trapezoidal plate 13, the slider 112 can move stably in a straight line, thereby enabling the tension sprocket 113 to stably provide tension to the chain 93.

[0033] refer to Figure 3 A fixing plate 14 is fixedly connected to the outer side of the trapezoidal plate 13, and a spring 15 is fixedly connected to the inner side of the fixing plate 14. The other end of the spring 15 is fixedly connected to the outer side of the slider 112.

[0034] As a technical optimization of this utility model, by setting a fixed plate 14 and a spring 15, when the support block 101 descends and the slider 112 is pushed outward by the connecting rod 111, the spring 15 between the slider 112 and the fixed plate 14 will be squeezed, deformed and generate a rebound force. Then, when the support block 101 rises and the slider 112 is limited by the trapezoidal plate 13, the rebound force of the spring 15 will assist it, making it easier for the connecting rod 111 to pull the slider 112 inward.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to inspect the wire rope, the wire rope is first placed on the first pulley 4. Then, the electric telescopic rod 102 is activated, driving the support block 101 to lower the second sprocket 92 and the second pulley 5 until the wire rope is clamped by the first pulley 4 and the second pulley 5. At the same time, during this process, the connecting rod 111 rotates due to the descent of the support block 101, pushing the slider 112 outward and driving the tension sprocket 113 to move together. Therefore, under the action of the tension sprocket 113, when the distance between the first sprocket 91 and the second sprocket 92 changes, the chain 93 used for transmission between them always maintains a suitable tension. Therefore, to prevent chain 93 from falling off during this process, motor 3 can then be started to drive the first pulley 4 to rotate, and the first toothed block to drive the second gear 8 to rotate. Then, the first sprocket 91 rotates with the second gear 8, and drives the second sprocket 92 to rotate through the chain 93. The rotation of the second gear 8 is stably transmitted to the second sprocket 92, which in turn drives the second pulley 5 connected to it to rotate. Finally, the first pulley 4 and the second pulley 5 rotate synchronously in a symmetrical direction. This ensures that the wire rope will not slip when it is stretched at both ends, and the tension at both ends is consistent. At this point, the state of the wire rope can be checked by the detection device 2, thus providing the advantage of auxiliary force uniformity detection.

[0036] In summary, this wire rope detection device for lifting equipment, by setting a first gear 7 and a second gear 8, allows the wire rope to be clamped by the first pulley 4 and the second pulley 5 after the lifting assembly 10 drives the second pulley 5 to descend. During detection, the motor 3 is started, driving the first pulley 4 to rotate, which in turn drives the first gear 7 to rotate. Subsequently, the second gear 8 rotates in the opposite direction to the first pulley 4. Then, through the transmission mechanism 9, the second pulley 5 finally rotates in the corresponding direction. This solves the problem that when only the first pulley is driven, the second pulley, as the driven pulley, cannot rotate synchronously with the first pulley in a symmetrical direction when the wire rope is pulled, resulting in slippage. Consequently, the tension on both ends of the wire rope is uneven, affecting the accuracy of the detection.
