Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a steel wire rope corner protection device. Background Art
[0002] In the field of building construction, especially in the metallurgical industry, for example, there are many silos and funnels under the batching room of sintering, which are located under the platform of the grid frame beam. When installing, mechanical equipment such as cranes cannot be used, and only manual hoists can be used for hoisting in reverse. At this time, due to the upper lifting rings and guide rails, the frame beam is often used as the lifting point. When installing with a steel wire rope striding across the beam and cooperating with a manual hoist, since the frame beam is rectangular in structure, in order to protect the upper edges and corners of the frame beam and the steel wire rope from being damaged, it is necessary to protect the upper edges and corners of the frame beam.
[0003] There are still some deficiencies in the existing lifting corner protectors during use. The existing lifting corner protectors only adhere to the surface of the frame beam. When connecting with the frame beam, they only adhere to the frame beam by tightening the steel wire rope. However, this connection method is very likely to cause the lifting corner protector to slide with the frame beam. Content of the Utility Model
[0004] In order to solve the above technical problems, the utility model provides a steel wire rope corner protection device to achieve the technical effect of improving the connection stability of the protection device and avoiding sliding during use.
[0005] To achieve this technical purpose, the utility model adopts the following scheme:
[0006] A steel wire rope corner protection device includes angle steels arranged symmetrically. Installation ears are respectively arranged at both ends of each angle steel, and the two installation ears on the same side are connected by a screw rod; arc-shaped plates are respectively arranged outside each angle steel, and both sides of the arc-shaped plate are respectively connected to the two side edges of the angle steel one by one. Baffles are respectively arranged at both ends of the arc-shaped plate on each angle steel.
[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0008] The utility model combines two angle steels into a set to protect the frame beam by the way of pulling with a screw rod, tightly adhering to the beam body, avoiding the movement of the angle steel during hoisting, and improving the stability of the device; baffles are respectively added at both ends of the arc-shaped plate, which can avoid the situation that the steel wire rope slides off the arc-shaped plate during hoisting.
[0009] Furthermore, the preferred scheme of the utility model is:
[0010] A number of stiffening ribs are arranged between the inner part of the arc-shaped plate and the surfaces of the two side edges of the angle steel. The strength and stiffness between the angle steel and the baffle are enhanced by the stiffening ribs.
[0011] The outer surface of the arc-shaped plate is provided with a wear-resistant layer, which improves the wear-resistant coefficient between the surface of the arc-shaped plate and the steel wire rope and extends the service life of the steel wire rope and the arc-shaped plate.
[0012] The inner surfaces of the two sides of the angle steel are respectively provided with anti-slip layers, which increase the friction between the two inner surfaces of the angle steel and the frame beam and prevent the angle steel from sliding relative to the frame beam.
[0013] A number of sleeves are respectively arranged at intervals on the inner surfaces of the two sides of the angle steel. A ejector rod is slidably connected inside the sleeve. One end of the ejector rod is placed inside the sleeve and connected to the inner wall of the sleeve through a spring. The other end of the ejector rod extends to the outside of the sleeve and a top block is arranged at its end. The spring makes the angle steel fit more closely with the frame beam.
[0014] The surface of the top block is provided with an anti-slip layer. Description of the Drawings

[0021] To fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific embodiments, but the present invention is not limited thereto. Embodiment 1:
[0022] A steel wire rope corner protection device is made up of two symmetrically arranged angle steels 2. Installation ears 7 are welded to the front and rear ends of each angle steel 2 respectively. Through holes are provided on the installation ears 7. The two angle steels 2 are respectively placed on both sides of the top of the frame beam 1, and the inner side surfaces of the angle steels 2 are in contact with the surface of the frame beam 1. The two installation ears 7 on the same side are tensioned by a screw rod 5 passing through the through holes, so that the two angle steels 2 connect the frame beam 1.
[0023] An arc-shaped plate 3 is respectively buckled on the outer part of each angle steel 2. The two sides of the arc-shaped plate 3 are respectively welded and fixed to the outer surfaces of the two side edges of the angle steel 2 in one-to-one correspondence. Arc-shaped baffles 4 are respectively welded to the front and rear ends of the arc-shaped plate 3 on each angle steel 2. The radius of the baffle 4 is greater than the radius of the arc-shaped plate 3.
[0024] In this embodiment, in order to enhance the strength of the arc-shaped plate 3, stiffening ribs 9 are respectively welded between the outer surfaces of the two side edges of the angle steel 2 and the bottom of the arc-shaped plate 3.
[0025] A wear-resistant layer is provided on the outer surface of the arc-shaped plate 3, and a lubricant is sprayed on the surface of the wear-resistant layer. The wear-resistant layer can increase the wear-resistant coefficient between the steel wire rope 8 and the arc-shaped plate 3, and spraying the lubricant can reduce the friction between the steel wire and the arc-shaped plate 3, reduce the wear of the steel wire rope 8, and extend the service life of the steel wire rope 8 and the arc-shaped plate 3.
[0026] An anti-slip layer 10 is respectively provided on the inner wall of each angle steel 2. The angle steel 2 is in contact with the frame beam 1 through the anti-slip layer 10, and the anti-slip layer 10 increases the friction between the frame beam 1 and the angle steel 2.
[0027] When this device is specifically applied, the inner sides (inner corners) of the two angle steels 2 are buckled on the outer corners of the upper part of the beam body, and then the screw rod 5 passes through the installation ears 7 on the two angle steels 2 and the two angle steels 2 are locked by nuts 6 to form a whole, so that the two angle steels 2 are fixed on the frame beam 1; a lubricant is sprayed on the wear-resistant layer surface of the arc-shaped plate 3 on each angle steel 2, and then the steel wire rope 8 is placed between the two baffles 4 and sequentially bypasses the arc-shaped plates 3 outside the two angle steels 2. The two baffles 4 limit the steel wire rope 8, and the installation of the steel wire rope 8 corner protection device is completed above.
[0028] This embodiment is simple to operate, convenient to manufacture, and can be reused. During the installation process, the two angle steels 2 are connected into a whole through the screw rod 5, so that the angle steels 2 are not easy to slide relative to the frame beam 1, and the structure is stable and reliable. Embodiment Two:
[0029] The difference between this embodiment and the first embodiment lies in that: several sleeves 11 are respectively arranged at intervals on the inner surfaces of the two side marks of the angle steel 2. A ejector rod 12 is slidably connected to the inside of each sleeve 11. One end of the ejector rod 12 is placed inside the sleeve 11 and is connected to the inner wall of the sleeve 11 through a spring 13. The other end of the ejector rod 12 extends to the outside of the sleeve 11 and is fixedly connected with an ejector block 14 at its end. An anti-slip layer 10 is arranged on the surface of the ejector block 14.
[0030] In this embodiment, the inner surface of the angle steel 2 tightly presses against the frame beam 1 through the spring 13 and the ejector block 14, making the angle steel 2 fit more closely with the frame beam 1.
[0031] Finally, it should be noted that: the above-listed are only the preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and its equivalent technologies, they should all be considered as the protection scope of the present invention.
