Description

Technical Field

[0001] This utility model relates to the field of installation auxiliary tools, specifically a wrapping pad installation tool. Background Technology

[0002] Spiral wound gaskets are high-performance, high-reliability sealing gaskets, typically made of alternating layers of metal strips (such as V-shaped steel strips) and non-metallic strips (such as graphite, asbestos, PTFE, and other soft materials). The metal strips are fixed at the beginning and end by spot welding to form a ring-shaped gasket structure. Based on their structure, spiral wound gaskets can be classified into four types: basic type, type with inner ring, type with outer ring, and type with both inner and outer rings. Spiral wound gaskets with both inner and outer rings are commonly used for flat and raised face flanges to enhance sealing performance and positioning stability.

[0003] Spiral wound gaskets are widely used for sealing flange connections in industries such as petroleum, chemical, power, shipbuilding, and machinery due to their excellent performance and wide applicability. They perform particularly well in applications with uneven loads, loosening of joint forces, periodic temperature and pressure changes, and impacts or vibrations.

[0004] However, in practical applications, the installation of traditional spiral wound gaskets relies on manual operation, such as using screwdrivers, pliers, and other tools to press the gasket into the sealing groove. This method is not only inefficient but also prone to damage to the gasket or inaccurate installation due to improper operation, thus affecting the sealing effect. Utility Model Content

[0005] The purpose of this invention is to provide a spiral wound gasket installation tool to solve the problem mentioned in the background art, which states that the installation of traditional spiral wound gaskets relies on manual operation, such as using screwdrivers, pliers, or other tools to press the gasket into the sealing groove. This method is not only inefficient, but also prone to damage to the spiral wound gasket or inaccurate installation position due to improper operation, thereby affecting the sealing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a connecting flange, a spiral wound gasket, and a tool body, wherein a sealing groove for installing the spiral wound gasket is provided on the upper end face of the connecting flange;

[0007] Operating handles are fixedly installed on both sides of the tool body. Control power boxes are fixedly installed on both sides of the upper end of the tool body. A positioning groove that matches the outer end of the connecting flange is opened in the middle of the lower end face of the tool body. A cross support frame is fixedly installed on the upper end of the tool body. An electric telescopic rod is fixedly installed through the middle of the upper end of the cross support frame. A lifting plate is fixedly installed on the lower telescopic part of the electric telescopic rod. A limit slide rod is fixedly installed on the upper end of the lifting plate. An installation groove is opened on the lower end face of the lifting plate. An internal gear transmission ring is rotatably connected to the inner wall of the installation groove through a rotating shaft. A drive motor is fixedly installed on the upper side of the lifting plate. A transmission gear is fixedly installed through the transmission shaft of the drive motor through the lifting plate. An installation plate is fixedly installed on the lower end of the internal gear transmission ring. A ball seat is fixedly supported on the lower end face of the installation plate. A ball wheel for rolling and squeezing the winding pad is rotatably connected to the lower end of the ball seat.

[0008] Preferably, there are two operating handles, symmetrically distributed on both sides of the tool body, and a mobile power supply is fixedly installed inside the control power box.

[0009] Preferably, the tool body has a through hole in the middle.

[0010] Preferably, there are several limiting slide rods, which are symmetrically distributed around the upper end of the lifting plate, and the upper end of each limiting slide rod is movably connected to the upper end of the cross support frame.

[0011] Preferably, the outer end of the transmission gear is meshed with the internal gear transmission ring.

[0012] Preferably, there are several ball seats, which are symmetrically distributed with respect to the lower end face of the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the spiral wound gasket is aligned with the upper opening of the sealing groove, the positioning groove and the outer end of the connecting flange are fitted together. When the positioning groove and the outer end of the connecting flange are fitted together, the electric telescopic rod is extended downward by control. When the electric telescopic rod extends downward, it will drive the lifting plate to move downward in a straight line. When the lifting plate moves downward in a straight line, it will drive the mounting plate to move downward in a straight line through the internal gear transmission ring. When the mounting plate moves downward in a straight line, it will drive the ball wheel to move downward in a straight line through the ball seat. When the ball wheel moves downward in a straight line, it will squeeze the spiral wound gasket at the upper opening of the sealing groove, so that the spiral wound gasket is squeezed and installed into the sealing groove, thereby realizing the function of facilitating the squeezing and installation of the spiral wound gasket.

[0015] This invention also features a drive motor that, when turned on, drives a transmission gear to rotate. This rotation of the transmission gear meshes with and drives an internal gear transmission ring to rotate. The rotation of the internal gear transmission ring, in turn, drives a mounting plate to rotate. The rotation of the mounting plate, in turn, drives a ball seat to rotate. The rotation of the ball seat, in turn, drives a ball wheel to rotate. When the ball wheel rotates, it rolls and compresses the winding pad, thus achieving both compression and installation of the winding pad. This ensures that the winding pad is evenly stressed during installation, preventing misalignment and damage. Attached Figure Description

[0021] Please see Figure 1-3 This utility model provides a technical solution for a spiral wound gasket installation tool: it includes a connecting flange 1, a spiral wound gasket 2 and a tool body 3, and a sealing groove 4 for installing the spiral wound gasket 2 is provided on the upper end face of the connecting flange 1;

[0022] Operating handles 5 are fixedly installed on both sides of the tool body 3, and there are two operating handles 5, which are symmetrically distributed on both sides of the tool body 3. Control power boxes 6 are fixedly installed on both sides of the upper end of the tool body 3, and a mobile power supply is fixedly installed inside the control power box 6. A positioning groove 7 that matches the outer end of the connecting flange 1 is opened in the middle of the lower end face of the tool body 3, and a through hole is opened through the middle of the tool body 3. A cross support frame 8 is fixedly installed on the upper end of the tool body 3. An electric telescopic rod 9 is fixedly installed through the middle of the upper end of the cross support frame 8. A lifting plate 10 is fixedly installed on the lower telescopic part of the electric telescopic rod 9. A limit slide rod 11 is fixedly installed on the upper end of the lifting plate 10, and there are several limit slide rods 11, which are symmetrically distributed on the upper end of the lifting plate 10. The upper end of the limit slide rod 11 is through and fits against the movement. Connected to the upper end of the cross support frame 8, the lifting plate 10 is vertically and linearly limited by the limiting slide rod 11. The lower end face of the lifting plate 10 is provided with a mounting groove 12. The inner wall of the mounting groove 12 is rotatably connected to an internal gear transmission ring 13 via a rotating shaft. The upper end of the lifting plate 10 is fixedly installed with a drive motor 14. The lower end of the drive motor 14 passes through the lifting plate 10 and is fixedly installed with a transmission gear 15. The outer end of the transmission gear 15 is meshed with the internal gear transmission ring 13. The lower end of the internal gear transmission ring 13 is fixedly installed with a mounting plate 16. The lower end face of the mounting plate 16 is supported and fixedly installed with a ball seat 17. There are several ball seats 17, which are symmetrically distributed with rotation around the lower end face of the mounting plate 16. The lower end of the ball seat 17 is rotatably connected with a ball wheel 18 for rolling and squeezing the winding pad 2.

[0023] Working principle: In use, this utility model aligns the spiral wound gasket 2 with the upper opening of the sealing groove 4. When the spiral wound gasket 2 is aligned with the upper opening of the sealing groove 4, the positioning groove 7 is fitted with the outer end of the connecting flange 1. When the positioning groove 7 is fitted with the outer end of the connecting flange 1, the electric telescopic rod 9 is extended downward by control. When the electric telescopic rod 9 extends downward, it drives the lifting plate 10 to move downward in a straight line. When the lifting plate 10 moves downward in a straight line, it drives the mounting plate 16 to move downward in a straight line through the internal gear transmission ring 13. When the mounting plate 16 moves downward in a straight line, it drives the ball wheel 18 to move downward in a straight line through the ball seat 17. When the ball wheel 18 moves downward in a straight line, it squeezes the spiral wound gasket 2 at the upper opening of the sealing groove 4, so that the spiral wound gasket 2 is squeezed and installed into the sealing groove 4, thereby facilitating the squeezing and installation of the spiral wound gasket 2.

[0024] Simultaneously, when the ball wheel 18 moves downward in a straight line to compress the winding pad 2, the drive motor 14 is activated. When the drive motor 14 is activated, it drives the transmission gear 15 to rotate. When the transmission gear 15 rotates, it meshes and drives the internal gear transmission ring 13 to rotate. When the internal gear transmission ring 13 rotates, it drives the mounting plate 16 to rotate. When the mounting plate 16 rotates, it drives the ball seat 17 to rotate. When the ball seat 17 rotates, it drives the ball wheel 18 to rotate. When the ball wheel 18 rotates, it can roll and compress the winding pad 2. This achieves both compression and rolling compression of the winding pad 2 during installation, ensuring that the winding pad 2 is evenly stressed during installation, preventing misalignment, and avoiding damage to the winding pad 2.
