Description

Technical Field

[0001] This utility model relates to the field of heating surface hanger installation technology, and specifically to a heating surface hanger adjustment device. Background Technology

[0002] Heating surface hangers are key structural components in boilers and other thermal equipment used to suspend heating surface equipment (such as water-cooled walls, superheaters, reheaters, economizers, etc.). Their main function is to suspend the heating surface components on the boiler steel frame or furnace top beam grid, while accommodating the thermal expansion displacement of the heating surface during operation, ensuring the safe and stable operation of the equipment.

[0003] During the construction of boilers in thermal power plants, the installation accuracy of heating surface equipment (hereinafter referred to as equipment), such as water-cooled walls, superheaters, reheaters, and economizers, directly affects the operating efficiency and safety of the boiler. After these devices are assembled with the hangers, their elevation needs to be adjusted by the hangers to ensure that the equipment is at the same level. If the equipment is not installed horizontally, uneven force on the hangers will cause additional stress to be generated in the local structure. Long-term operation may cause equipment deformation, weld cracking, or even tube bank rupture, which may threaten the safe operation of the boiler or even cause a shutdown accident.

[0004] The elevation adjustment of the boom is usually achieved by using a large crane to lift the equipment. Specifically, the bottom of the boom is connected to the heated surface equipment, the boom passes through the installation platform, and the boom is lifted by the crane. The height of the equipment is adjusted by adjusting the height of the boom upwards. After adjusting to the target elevation, a lock nut is screwed on the externally threaded boom, so that the lock nut abuts against the installation platform. The clamping force between the internal thread of the lock nut and the external thread of the boom causes the installation platform to support the boom and the equipment upwards, thereby fixing the height of the boom. This traditional adjustment method has revealed many problems in practical applications: (1) For the adjustment of a row of booms, it is necessary to frequently use wire rope hoisting equipment. Each adjustment requires a cumbersome process of hoisting, positioning, and fixing. The adjustment of a single row of booms takes a long time and seriously affects the construction progress; (2) When using a crane to adjust the booms at the same location, the crane's operating range will occupy a large amount of construction space, directly restricting the hoisting work of other equipment, causing the construction connection between various processes to be hindered, and thus affecting the overall construction period; (3) The rental and operation costs of large cranes are high, and crane resources need to be occupied for a long time during the boom adjustment process, resulting in a significant increase in construction costs. In summary, there is an urgent need for a new type of heating surface boom adjustment device that can overcome the above defects. Utility Model Content

[0005] The present invention aims to provide a heating surface suspension rod adjustment device, which, by operating a jack, slowly lifts the suspension rod and the connected heating surface equipment, thereby moving the suspension rod and the connected heating surface equipment up and down, and achieving precise adjustment of the suspension rod elevation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heating surface hanger adjustment device includes a base plate, a partition plate, a vertical plate, and at least two reinforcing plates. The vertical plates are symmetrically fixed to both sides of the base plate. The partition plate is fixedly connected between the two vertical plates and has a through hole in the middle for the hanger to pass through. The reinforcing plates are fixed between the vertical plates and the base plate. After the hanger passes through the through hole, it is height-locked by a locking device that cooperates with the mounting platform and the partition plate. The device also includes a lifting device for lifting the base plate upward.

[0008] The optimized lifting device is specifically a jack.

[0009] The optimized locking element is a locking nut.

[0010] The optimized spacing between the two reinforcing plates is at least 180mm.

[0011] The optimized version is that the base plate, partition plate, and reinforcing plate are made of sheet metal.

[0012] In the optimized configuration, the reinforcing plate is fixedly connected to the vertical plate and the bottom plate by welding to form a rigid support structure.

[0013] Optimized, the locking nuts are at least two.

[0014] The working principle and beneficial effects of this utility model:

[0015] When adjusting the elevation of the heating surface hanger, the hanger is pre-screwed into the bottom locking nut, which abuts against the upper surface of the external installation platform. At this time, the installation platform supports the hanger and the heating surface equipment upward through the bottom locking nut, forming the initial suspension state.

[0016] The device is then placed on a solid mounting platform, serving as a stable support foundation for the entire adjustment system. The boom passes through the through-hole in the middle of the partition, positioning it in the central adjustment position. Next, a top locking nut is screwed into the top of the boom, ensuring its lower surface is tightly against the upper surface of the partition. At this point, the top locking nut, partition, vertical plate, and base plate form a rigid connection, securing the boom within the device. A jack is placed on the mounting platform, lifting the base plate upwards. This causes the boom and connected heating surface equipment to move up and down. The bottom locking nut moves upwards with the boom, disengaging from the mounting platform. Once the boom is adjusted to the elevation specified in the design drawings, the bottom locking nut is tightened downwards, ensuring it is tightly against the mounting platform, thus fixing the boom height.

[0017] Existing technologies rely on large cranes for hoisting and adjusting booms, resulting in high crane rental and operating costs. Furthermore, adjusting a single-row boom requires repeated hoisting, leading to long machine downtime. The large operating radius of cranes also occupies significant construction space, hindering the simultaneous hoisting of other equipment and impacting workflow. This application replaces cranes with jacks as the power source for adjustment, eliminating the need for frequent crane use and avoiding resource waste caused by prolonged crane occupation. The base plate is placed directly on the installation platform, resulting in a compact design and minimal space occupation. Secondly, the double-nut, jack-based adjustment mechanism eliminates the need for a complete hoisting system. During adjustment, the lifting force is transmitted through the contact between the top locking nut and the partition plate, directly moving the boom up and down, shortening adjustment time and thus reducing the construction period.

[0024] The following detailed description illustrates the specific implementation method:

[0025] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0026] Example: A heating surface hanger adjustment device includes a base plate 7, a partition plate 10, a vertical plate 8, and a reinforcing plate 6. The vertical plates 8 are symmetrically fixed on both sides of the base plate 7. The partition plate 10 is fixedly connected between the two vertical plates 8 and has a through hole in the middle for the hanger 4 to pass through. The reinforcing plate 6 is fixed between the vertical plate 8 and the base plate 7. The reinforcing plate 6 is fixedly connected to the vertical plate 8, the base plate 7, the partition plate 10, and the base plate 7 by welding to form a rigid support structure.

[0027] like Figure 1As shown, when adjusting the elevation of the boom 4, the installation platform 1 and the ground are fixed upward to form a support. The installation platform 1 is provided with an installation hole for the boom 4 to pass through. The boom 4 is lifted by a crane and screwed into the bottom locking nut 3. The bottom locking nut 3 abuts against the upper surface of the external installation platform 1. At this time, the installation platform 1 supports the boom 4 and the heated surface equipment 2 upward through the bottom locking nut 3, forming an initial suspended state. The crane can then leave to carry out other operations.

[0028] like Figure 2 As shown, the lifting rod 4 is passed through the through hole in the middle of the partition 10, so that the lifting rod 4 is in the center adjustment position of the device. Then, the top locking nut 9 is screwed into the top of the lifting rod 4, so that the lower surface of the top locking nut 9 is in close contact with the upper surface of the partition 10. At this time, the top locking nut 9, the partition 10, the vertical plate 8 and the bottom plate 7 form a rigid connection, as shown. Figure 3 As shown, jacks 5 are symmetrically placed on the installation platform 1. Jacks 5 lift the base plate 7 upwards, thereby moving the lifting rod 4 and the connected heating surface equipment 2 upwards. The bottom locking nut 3 moves upwards with the lifting rod 4 and disengages from the installation platform 1. When the lifting rod 4 is adjusted to the elevation position required by the design drawings, as shown... Figure 4 As shown, by tightening the bottom locking nut 3 downwards, the bottom locking nut 3 is brought into tight contact with the mounting platform 1, thus fixing the height of the boom 4. Figure 5 As shown, unscrew the top locking nut 9, then remove the device upwards, and then remove the jack 5, thereby completing the height adjustment of the boom 4 and the heated surface equipment 2.

[0029] Existing technology relies on large cranes to lift and adjust the boom 4, resulting in high crane rental and operating costs. Furthermore, adjusting a single-row boom 4 requires repeated lifting, leading to long machine downtime. The large operating radius of the crane during adjustment also occupies significant construction space, hindering the simultaneous lifting of other equipment and impacting workflow. This application replaces the crane with a jack 5 as the adjustment power source, eliminating the need for frequent crane use and avoiding resource waste caused by prolonged crane occupation. The base plate 7 is placed directly on the installation platform 1, resulting in a compact size and minimal space occupation. Secondly, the double-nut, jack 5 adjustment mechanism eliminates the need for overall lifting equipment. During adjustment, the lifting force is transmitted through the contact between the top locking nut 9 and the partition plate 10, directly moving the boom 4 and shortening the adjustment time, thus reducing the construction period.
