A kind of boiler heating surface tube row anti-abrasion tile installation auxiliary device

Abstract

A kind of boiler heating surface tube bank anti-abrasion tile installation auxiliary device. Because the tube bank pitch is small, the installation of anti-abrasion tile is inconvenient, and personnel cannot install anti-abrasion tile on the fourth and fifth layers of tube bank due to the small tube bank pitch. The tube bank pitch is enlarged by cutting the positioning block and using a chain hoist, which greatly increases the workload. The utility model discloses a support frame, the support frame is rotatably connected with two rotating rods, the upper and lower ends of the two rotating rods are respectively connected with rotating clamping rods for pressing anti-abrasion tiles, and the upper part of the fixing screw of the support frame is connected with an adjusting seat for adjusting the position of the upper rotating clamping rod. The utility model is used for the installation of anti-abrasion tiles on the boiler heating surface tube bank.

Description

Technical Field

[0001] This utility model relates to an auxiliary device for installing anti-wear tiles on boiler heating surface tubes. Background Technology

[0002] Currently, due to changes in the quality of coal fed into power plants, a large amount of ash adheres to the heating surface tubes, affecting heat absorption, especially at the tail end of the heating surface. The tail end heating surfaces mostly use steam purging technology, which causes some damage to the tubes. A common method to avoid steam purging is to install wear-resistant tiles. For transversely arranged tubes such as economizers and low-temperature superheaters, wear-resistant tiles are installed on the first, second, and third layers of tubes at the factory. However, the small tube pitch makes the installation of these tiles difficult. Because the pitch is too small, personnel cannot install wear-resistant tiles on the fourth and fifth layers; instead, they have to cut the positioning blocks and use a chain hoist to increase the tube pitch, significantly increasing the workload.

The upper and lower ends of the two rotating rods are respectively connected to rotating clamps for pressing the wear-resistant tiles. The upper part of the fixing screw of the support frame is connected to an adjusting seat for adjusting the position of the upper rotating clamps.

[0005] The auxiliary device for installing anti-wear tiles on boiler heating surface tubes includes a support frame comprising two supports arranged vertically, which are fixedly connected by a fixing screw.

[0006] The auxiliary device for installing wear-resistant tiles on boiler heating surface tubes includes a rotating clamp rod comprising a clamp plate connected to each rotating rod, and the two clamp plates are connected by a connecting rod.

[0007] The auxiliary device for installing anti-wear tiles on boiler heating surface tubes includes an adjusting seat comprising a limiting clamp, the middle part of which is connected to a threaded sleeve via a bearing, and the threaded sleeve being threadedly connected to a fixing screw. Beneficial effects

[0008] 1. This utility model can compact the wear-resistant tiles that need to be installed onto the fifth tube bundle, and then weld them at the connection between the reinforcing bars and the first row of tube bundles. After completion, the wear-resistant tiles with two reinforcing bars are placed on the fourth tube bundle from the other side. After adjusting the device, the wear-resistant tiles on the fourth tube bundle are compacted onto the fourth tube bundle. After compaction, they are sequentially welded onto the wear-resistant tiles of the first, second, and third tube bundles that can be touched by the welding rod, thus realizing the installation and compaction of the wear-resistant tiles.

[0009] 2. This utility model can adjust the distance between the two rotating clamps to facilitate the compaction of the anti-wear tiles at different positions, thereby improving installation efficiency. Attached Figure Description

[0011] Reference Figures 1-5 An auxiliary device for installing wear-resistant tiles on boiler heating surface tubes includes a support frame 17, on which two rotating rods 12 are rotatably connected. The support frame includes two supports 7 arranged vertically, and the two supports are fixedly connected by a fixing screw. The rotating rod includes a round rod segment 5 located on the lower side and a square rod segment 3 located on the upper side, and the support is rotatably connected to the rotating rod; The upper and lower ends of the two rotating rods are respectively connected to rotating clamping rods 16 for pressing the anti-wear tile 15; There are two rotating clamping rods, which are connected to the upper and lower ends of the rotating rod respectively. The rotating clamping rod at the lower end includes two lower clamping plates 6. Each rotating rod has a lower clamping plate fixed at its bottom, and the two lower clamping plates are connected by a lower connecting rod 8. The rotating clamp at the upper end includes two upper clamping plates 2. Each rotating rod has an upper clamping plate slidably connected to its top. The upper clamping plates have square holes that mate with the square rod section of the rotating rod. The two upper clamping plates are connected by an upper connecting rod 1. The upper part of the fixing screw 4 of the support frame is connected to an adjustment seat 18 for adjusting the position of the upper rotating clamp rod.

[0012] The adjusting seat includes a limiting clamp 11, which clamps the upper clamp at both ends. The middle part of the limiting clamp is connected to the screw sleeve 10 through a bearing. The screw sleeve is threadedly connected to the fixing screw. Two sliding rods 9 are fixed at the bottom of the limiting clamp. The bottom of the sliding rods passes through the round hole on the support and slides. Working principle: When using it, refer to... Figures 6-8First, weld the anti-wear tile 15 to two steel bars 14. After welding, hold the steel bars and place the anti-wear tile on the fifth tube bundle 13. Then, hold one of the rotating rods and rotate it to rotate the clamping rod. At this time, the device can be placed between two adjacent tube bundles. After placement, the lower rotating clamping rod should be positioned between the fifth and fourth tube bundles 19. Then, rotate the screw sleeve to adjust the position of the upper rotating clamping rod. After adjustment, it should be positioned between the first and second tube bundles. After adjustment, rotate the rotating rod to rotate the upper and lower rotating clamping rods. After the upper rotating clamping rod rotates, it should be positioned between the first and second tube bundles, and after the lower rotating clamping rod rotates, it should be positioned between the fifth and fourth tube bundles. After rotation, press the lower rotating clamping rod onto the anti-wear tile of the fifth tube bundle. Continue to rotate the screw sleeve to adjust the position of the upper rotating clamping rod, so that it is pressed tightly against the bottom of the first tube bundle. This can compact the anti-wear tile on the fifth tube bundle. Then, weld the steel bar to the anti-wear tile on the first tube bundle. After welding, rotate the screw sleeve to limit... The positioning clamp moves the upper rotating clamp rod downwards, releasing it from its compressed state. Then, the rotating rod is rotated so that the rotating clamp rod is positioned between two adjacent tube bundles. The device is then removed, and from the other side, the wear-resistant tile with two welded steel bars is placed on the fourth tube bundle 19. The device is then inserted, positioning its lower rotating clamp rod between the fourth and third tube bundles. The screw sleeve is rotated, and the limiting clamp moves the upper rotating clamp rod to adjust its position, positioning it between the first and second tube bundles. Then, the rotating rod is rotated so that the upper... After the rotating clamp at the end rotates, it is positioned between the first and second tube bundles. After the rotating clamp at the lower end rotates, it is positioned between the fourth and third tube bundles. Press the lower rotating clamp onto the wear-resistant tile of the fourth tube bundle. Rotate the screw sleeve to adjust the position of the upper rotating clamp so that it is firmly pressed against the bottom of the first tube bundle and stops.
