A type of I-beam wheel for pipe machinery cradle

Abstract

This utility model provides an I-beam wheel for a tubular machine cradle, belonging to the technical field of I-beam wheels. The I-beam wheel consists of a cylindrical body and end plates welded to both sides of the cylindrical body. The end plates have a stepped portion protruding outward from the side away from the cylindrical body, and a brake band groove is recessed circumferentially along the stepped portion for mounting a brake belt. This utility model's I-beam wheel for a tubular machine cradle features a circumferential brake band groove on the stepped portion outside the end plate, allowing for direct mounting of the brake belt. During braking, the friction between the belt and the brake band groove achieves an emergency stop for the I-beam wheel, eliminating the need for a traditional independent brake disc structure and saving cradle space.

Detailed Implementation

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figure 1 , Figure 2 , Figure 4 As shown, this utility model provides an I-beam wheel for a pipe machine cradle. The I-beam wheel 10 is composed of a cylinder 1 and end plates 2 welded to both sides of the cylinder 1.

[0021] In this embodiment, specifically, as shown in... Figure 5 As shown, the cylinder 1 is made of seamless steel pipe with a wall thickness of 6mm and is processed into a hollow cylindrical shape. First limiting protrusions 11 are provided at both ends of the cylinder 1, and annular grooves 12 are formed on the inner side of the protrusions for positioning the end plate 2. A 10mm diameter cable threading hole 13 is provided at one-third of the cylinder body to facilitate cable threading.

[0022] In this embodiment, specifically, as shown in... Figure 4 , Figure 5 , Figure 8 As shown, the end plate 2 is a hollow disc structure. The end plate 2 has a stepped part 21 protruding outward on the side away from the cylinder 1. The end plate 2 is connected to the cylinder 1 and has a protrusion 22 protruding outward. The protrusion 22 is fitted into the groove 12. A 75° bevel is opened on the outside of the first limiting protrusion 11 and fully welded. After welding, the weld is ground to the rounded corner to ensure that there is no interference when winding the wire.

[0023] In this embodiment, specifically, as shown in... Figure 5 , Figure 6 As shown, the step portion 21 is circumferentially machined with a brake band groove 211. The groove surface is treated with full rounded corners. The full rounded corner design of the brake band groove 211 disperses stress and avoids vibration. During braking, the belt rubs against the brake band groove 211 to achieve emergency stop of the I-beam wheel, eliminating the need for the traditional independent brake disc structure.

[0024] In this embodiment, specifically, as shown in... Figure 3 As shown, four evenly distributed pin holes 23 are provided around the stepped part 21 for precise positioning of the I-beam wheel 10.

[0025] In this embodiment, specifically, as shown in... Figure 4 , Figure 6 , Figure 7 As shown, the end plate 2 has a mounting groove 24 in the center, and a top 3 is embedded inside the mounting groove 24. The top 3 has a cylindrical structure, and a second limiting protrusion 31 protrudes from the middle of the top 3.

[0026] In this embodiment, specifically, as shown in... Figure 4 , Figure 9 As shown, the mounting groove 24 includes a top protrusion limiting groove 241 and a retaining spring limiting groove 242. The diameter of the retaining spring limiting groove 242 is larger than the diameter of the top protrusion limiting groove 241. A second limiting protrusion 31 is embedded in the top protrusion limiting groove 241. A retaining spring 4 is secured on the side of the second limiting protrusion 31 away from the cylinder 1. The retaining spring 4 is embedded in the retaining spring limiting groove 242. The top protrusion 3 is embedded in the top protrusion limiting groove 241 of the end plate through the second limiting protrusion 31, and is fixed on the outside by the retaining spring 4 being engaged in the retaining spring limiting groove 242. When the top protrusion 3 is damaged, only the retaining spring needs to be removed to replace the top protrusion 3; there is no need to replace the entire I-beam wheel 10.

[0027] In this embodiment, specifically, as shown in... Figure 3 As shown, the end plate 2 has an end plate wire hole 25 on the side away from the cylinder 1. There are four end plate wire holes 25 evenly distributed around the circumference. The end plate 2 has four pin holes 23 symmetrically opened for positioning. The four wire holes 25 assist in the cable arrangement. The cable is radially inserted from the cylinder wire hole 13 of the cylinder 1 and axially led out through the end plate wire hole 25 of the end plate 2 to achieve multi-path arrangement.

[0028] The working process of the I-beam wheel for a pipe-machine cradle according to this utility model: The I-beam 10 is placed on the support shaft of the pipe-making cradle. The center pin 3 guides the support shaft through, and the equipment pin is inserted into the pin hole 23 of the end plate 2 to restrict the circumferential rotational freedom of the I-beam 10. The brake belt is directly fitted into the brake belt groove 211 of the end plate to complete the brake system integration. The equipment sends a brake signal, the brake belt tightens, and the belt contacts the groove surface of the brake belt groove 211. The frictional resistance is converted into braking torque, which drives the I-beam 10 to stop rotating.

[0029] When the tip 3 is damaged, use snap ring pliers to remove snap ring 4, pull out tip 3 axially, press in a new tip 3, and snap in a new snap ring 4. There is no need to disassemble the main body 10 of the I-beam wheel.

[0030] The rounded fillet weld at the connection between cylinder 1 and end plate 2 eliminates cable scraping; The beneficial effects of this utility model of an I-beam wheel for a pipe machinery cradle are as follows: 1. The brake groove 211 is integrated into the end plate 2, eliminating the need for a separate brake disc and connecting parts, saving cradle space and avoiding bumps during the disassembly and assembly of the I-beam wheel 10.

[0031] 2. The split design of the top 3 improves replacement efficiency. Only the retaining ring 4 needs to be removed to replace the top 3, avoiding the scrapping of the entire H-beam wheel 10.

[0032] 3. The brake groove 211 is fully rounded around to enhance braking stability. The cylinder 1 and end plate 2 are fully welded and the rounded corner process ensures that there is no scratching when winding the wire.
