Description

Technical Field

[0001] This utility model belongs to the field of mechanical components and equipment, and specifically relates to a wire rope flaw detection device. Background Technology

[0002] Slope winch inspection is a key maintenance project in the factory. The wire rope of the slope winch must be inspected every month. During the inspection, two maintenance workers need to cooperate with the inspector to install the wire rope detector on the upper part of the wire rope. The operator holds the flaw detector to keep it stationary and stable. The wire rope passes through the flaw detector at a speed of 1m / s, which generates a metal cross-sectional area loss diagram and a metal wire breakage data diagram of the wire rope on the detection computer. The wire rope detector automatically analyzes the diagram and draws a conclusion, completing the flaw detection of the wire rope on the north and south sides.

[0003] Currently, the inspection process requires a large amount of manpower. During the inspection, the operator needs to maintain a balanced state at the upper opening of the inclined hoist for at least 15 minutes. During the inspection, the operator may not be able to maintain a balanced standing position for a long time, resulting in the inspection not meeting the requirements and requiring re-inspection, which makes the inspection efficiency unsatisfactory. In severe cases, the high viscosity of the lubricating oil in the wire rope can cause the wire rope flaw detector to stick to the wire rope, preventing it from moving normally on the wire rope. This can cause the operator to be dragged along with the wire rope flaw detector and fall, resulting in a safety accident. Utility Model Content

[0004] This invention provides a wire rope flaw detection device to solve the problems of insufficient operator safety and low detection efficiency in the existing hand-held wire rope flaw detectors.

[0005] The technical solution of this utility model is: a wire rope flaw detection device, including a wire rope flaw detector, a flaw detector base and a sliding rod. The flaw detector base is fixedly installed at the bottom of the wire rope flaw detector, and a spring is provided at the top of the sliding rod. The upper end of the spring is connected to the bottom of the flaw detector base.

[0006] As a further improvement of this utility model, it also includes a movable support, and a connecting seat is provided at the bottom of the movable rod, and the connecting seat is slidably sleeved on the movable support.

[0007] As a further improvement of this utility model, a pulley is installed at the lower end of the connecting seat, and the pulley can roll along the floating bracket.

[0008] As a further improvement of this utility model, the movable support is fixedly installed with legs on both sides, and the bottom of the legs is provided with fixing bolts for fixing to the stop device of the hoisting rail.

[0009] The beneficial effects of this utility model are as follows: This utility model uses a freely swinging movable rod connected to a wire rope flaw detector to replace manual wire rope inspection, maintaining the balance of the wire rope flaw detector and effectively reducing the number of re-inspections. A spring at the top of the movable rod allows it to automatically adjust up and down with the wire rope flaw detector. Simultaneously, relying on pulleys and a movable support, the movable rod automatically adjusts horizontally with the wire rope flaw detector during inspection, preventing the flaw detector from sticking to the wire rope due to high lubricant viscosity. This utility model is simple to assemble, easy to operate, reduces safety risks for operators, improves inspection efficiency, and is highly practical for slope hoist inspection.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1 As shown, a wire rope flaw detection device includes a wire rope flaw detector 1.

[0014] A wire rope flaw detection device further includes a flaw detector base 2 and a sliding rod 4. The flaw detector base 2 is fixedly installed at the bottom of the wire rope flaw detector 1. A spring is provided at the top of the sliding rod 3, and the other end of the spring is connected to the bottom of the flaw detector base 2.

[0015] It also includes a movable support 3, and a connecting seat 5 is provided at the bottom of the movable rod 4. The connecting seat 5 is slidably sleeved on the movable support 3.

[0016] A pulley 6 is installed at the lower end of the connecting seat 5, and the pulley 6 can roll along the movable bracket 3.

[0017] The movable support 3 is fixedly installed with legs 7 on both sides. The bottom of the legs 7 is provided with fixing bolts, which can be used to fix the movable support 3 to the stop device of the hoisting rail.

[0018] When using the device, first connect the wire rope flaw detector 1 to the wire rope of the inclined winch. The wire rope flaw detector 1 must completely cover the wire rope. Then, connect the wire rope flaw detector 1 to the testing computer and perform a trial run to confirm that the wire rope flaw detector 1 is working properly and connected to the wire rope correctly. Next, connect the support leg 7 to the stop device of the winch rail with fixing bolts. After connection, check whether the sliding rod 4 can be adjusted normally up and down and left and right. After confirming the connection, start the winch and set the winch to run at a speed of 1 m / s, so that the wire rope passes smoothly through the wire rope flaw detector 1 at a speed of 1 m / s. According to the wire rope metal cross-sectional area loss diagram and wire rope metal broken wire number diagram generated by the testing computer, analyze whether the cross-sectional area loss and broken wires are within the standard range, thus completing the wire rope inspection.
