Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary devices for material hoisting, and particularly to a single-leg type hanging unloading platform steel wire rope fixing rod anti-loosening device. Background Art

[0002] As is well known, a hanging unloading platform is a device for hoisting materials to reduce the labor consumption used for material processing, thereby improving the efficiency of material processing or packing and transportation. It is widely used in the field of material processing; the existing method for the steel wire rope of a hanging unloading platform is that one end is connected to the unloading platform, and the other end of the steel wire rope passes through a reserved hole in a shear wall or a beam and is hung on a fixing rod behind the reserved hole to bear force, and the fixing rod is generally fastened to the shear wall or the beam surface by bearing the tensile force of the steel wire rope; however, it is found in the use of the existing hanging unloading platform steel wire rope that during the process of hoisting materials and pulling the unloading platform, the steel wire rope will cause the rear-end fixing rod to loosen and even flip and slide together; when the pulling is over, the unloading platform suddenly drops back, causing a great impact on the steel wire rope and the fixing rod. Over time, it is extremely easy to cause wear of the steel wire rope and the fixing rod, and even premature scrapping due to fatigue and shear failure caused by the impact force before reaching the service life, which not only wastes materials but also easily leads to high-drop safety accidents of the unloading platform. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a single-leg type hanging unloading platform steel wire rope fixing rod anti-loosening device, which can fix the positions of the steel wire rope and the fixing rod during the process of hoisting materials and pulling the unloading platform, prevent the steel wire rope from causing the rear-end fixing rod to loosen and even flip and slide together, and buffer the impact on the steel wire rope fixing rod when the unloading platform suddenly drops back at the end of the work. It can reduce the wear of the steel wire rope and the fixing rod during long-term work, effectively extend the working life of the steel wire rope and the fixing rod, effectively improve the working efficiency of the fixing rod and the steel wire rope, and reduce the probability of high-drop safety accidents.

[0010] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0011] As Figure 1As shown in the figure, a loosening prevention device for a steel wire rope fixing rod of a single-leg type suspended unloading platform of the present invention includes a square steel pressing plate 1, a tying rod 2, a nut 3 and an anchor 4. A through hole is provided on the square steel pressing plate 1. The left end of the tying rod 2 passes through the through hole. A bolt is provided at the left end of the tying rod 2. Thread structures are provided on the outer side wall of the bolt and the inner side wall of the nut 3. The nut 3 is screwed onto the outer side wall of the bolt. A limiting groove is provided on the right side wall of the square steel pressing plate 1. A connecting frame is provided on the side wall of the tying rod 2. A connecting hole is provided on the anchor 4. The connecting frame passes through the connecting hole; Rotate the nut on the bolt to adjust the distance between the nut and the anchor to fix the whole device on the reserved hole. The position of the fixing piece can be fixed by using the square steel pressing plate, and the steel wire rope can be fixed by using the connecting member. During the process of hoisting materials and tying the unloading platform, the position of the steel wire rope and the fixing rod can be fixed to prevent the steel wire rope from loosening or even flipping and sliding together with the rear fixing rod. And when the unloading platform suddenly drops back at the end of the work, it can buffer the impact on the steel wire rope fixing rod, reduce the wear of the steel wire rope and the fixing rod during long-term work, effectively extend the working life of the steel wire rope and the fixing rod, effectively improve the working efficiency of the fixing rod and the steel wire rope, and reduce the probability of high-drop safety accidents.

[0012] A loosening prevention device for a steel wire rope fixing rod of a single-leg type suspended unloading platform of the present invention further includes a gasket 5. The gasket 5 is fixedly installed on the left side wall of the square steel pressing plate 1. The inner side wall of the gasket 5 is in contact with the outer side wall of the bolt; Rotate the nut on the bolt to an appropriate position.
