Description

Technical Field

[0001] The utility model relates to a device for on-site fracture detection of a towed steel wire rope, belonging to the technical field of steel wire rope detection equipment. Background Art

[0002] A steel wire rope is a helical steel wire bundle formed by twisting steel wires that meet the requirements of mechanical properties and geometric dimensions according to certain rules. A steel wire rope consists of steel wires, a rope core, and lubricating grease. First, multiple layers of steel wires are twisted into strands, and then, with the rope core as the center, a certain number of strands are twisted into a helical rope. During the use of a steel wire rope, it needs to bear the action of alternating loads. It has the characteristics of stable operation and high elasticity and can be used for lifting, towing, tensioning, and load-bearing. Its application is very common.

[0003] However, during the actual operation of a steel wire rope, due to frequent normal use, after multiple bendings, drags, and tensions by pulleys and drums, the toughness of the steel wire rope will decrease. When the steel wire rope contacts the outer surfaces of the hook head and the pulley, it will also cause wear on the outer surface of the steel wire rope, resulting in a reduction in the cross-sectional area of the steel wire rope and a decrease in the load-bearing capacity. The steel wire rope itself is also very affected by the environment. Heavy rain and sunlight can cause corrosion of the steel wire rope. The fracture of the steel wire rope will cause the falling off of the transported materials, which is very likely to lead to material transportation quality accidents and personal injury accidents. When a steel wire rope is towing a heavy object, if the steel wire rope breaks, due to the high elasticity of the steel wire rope, the steel wire rope is likely to cause catapulting injuries to nearby operators, and the losses caused are immeasurable. At present, there is no special equipment for detecting the steel wire rope in use. Operators observe the state of the steel wire rope by visual inspection during patrol. When the steel wire rope is long, it is difficult for the operators to observe all parts of the steel wire rope, and when the steel wire rope is bent and fractured, it cannot be detected in time, resulting in accidents. Therefore, it is very necessary to design a device that can detect the steel wire rope during towing on-site. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a movable on-site fracture detection device for a towed steel wire rope. This detection device can detect the steel wire rope that is being towed, tensioned, and load-bearing, and can give an alarm in time when the steel wire rope is bent and fractured, avoiding the occurrence of accidents.

An angle adjustment roller is installed between the upper end of one of the height adjustment plates and the detection support frame. The audible and visual alarm is fixed on the movable base. The audible and visual alarm is connected to the detection limit through a signal wire.

[0007] For the above-mentioned movable on-site fracture detection device for towing steel ropes, the steel rope detection sleeve is composed of two semi-circular steel plates. The detection steel rope is placed on the surface of the lower semi-circular steel plate, and the upper semi-circular steel plate is placed on the upper surface of the detection steel rope. There are connecting plate strips on both sides of the two semi-circular steel plates, and there are corresponding connection holes on the connecting plate strips. The two semi-circular steel plates are connected into one body by connecting bolts passing through the connection holes.

[0008] For the above-mentioned movable on-site fracture detection device for towing steel ropes, the height adjustment plate is composed of two rectangular steel strips.

In the detection support frame 2, a detection support shaft 3 and a detection support spring 4 are installed to support the steel wire rope detection sleeve 1. The detection limit 5 can monitor the swing of the steel wire rope detection sleeve 1. The height adjustment plate 6 is connected to the lower end of the detection support frame 2 and is used to adjust the height and angle of the detection support frame 2 and the steel wire rope detection sleeve 1. The movable base 8 can move the overall mechanism to detect each section of the detection steel wire rope. The sound and light alarm 9 gives an alarm through the signal of the detection limit 5.

[0023] The lower end of the detection support spring 4 is fixed on the center line of the bottom surface of the other end of the inner wall of the semi-circular arc-shaped steel plate of the detection support frame 2 through a rectangular steel block. The upper end of the detection support spring 4 is connected to the lower surface of the other end of the steel wire rope detection sleeve 1, and the detection support spring 4 supports the other end of the steel wire rope detection sleeve 1. When the detection steel wire rope 10 is loose or breaks, the steel wire rope detection sleeve 1 swings downward around the detection support shaft 3, and the detection support spring 4 contracts. When the steel wire rope detection sleeve 1 stops being stressed, the detection support spring 4 returns the steel wire rope detection sleeve 1 to its original position through its elastic force.
