Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler technology, specifically a rolling support device suitable for boiler saddles. Background Technology
[0002] A boiler is a device that converts fuel energy (such as chemical energy, electrical energy, etc.) into heat energy to heat water or generate steam. It is widely used in heating, industrial production, power generation and other fields.
[0003] Because boilers are usually operated with full liquid, they are very heavy under operating conditions. In addition, boilers will expand and contract with temperature during operation. If the expansion is not effectively released, it will be transferred to the pressure-bearing components (such as furnace, end caps, boiler shell, door holes, etc.), which will cause damage to the pressure-bearing components and leakage.
[0004] To release the expansion, the traditional method is to equip the boiler with a fixed saddle and a movable saddle. The saddle refers to the boiler's supporting base. One saddle is fixed to the foundation with anchor bolts, while the other saddle is not fixed to the foundation and can slide along the foundation. This structure still has some shortcomings:
[0005] 1. Due to the heavy weight of the boiler itself, the frictional resistance between the saddle and the foundation is relatively large, which may cause difficulty in sliding and affect the effective release of expansion.
[0006] 2. Because the saddle is not fixed to the foundation, the sliding direction is very arbitrary during sliding, which may cause deviation and pose a safety hazard of tipping over. In the event of an earthquake, it is even more likely to overturn. Utility Model Content
[0007] In view of the above-mentioned shortcomings in the related technologies, the purpose is to provide a rolling support device suitable for boiler saddles, so as to solve the technical problem that the frictional resistance between the saddle and the foundation is relatively large, which leads to difficulties in sliding, affects the effective release of expansion, and poses a safety hazard of tipping over.
[0008] The technical solution to achieve the objective is: a rolling support device suitable for boiler saddles, comprising:
[0009] At least two anchor bolts are symmetrically connected to the foundation, with one end of the anchor bolt connected to the foundation and the other end protruding from the foundation;
[0010] The bottom support is fitted onto the anchor bolt and connected to it. Its bottom contacts the foundation, and the other end of the anchor bolt protrudes from the bottom support.
[0011] A stop is connected at the middle position of the top of the bottom support, and is spaced apart from the anchor bolts, with space between the stop and the bottom support;
[0012] Several rollers are arranged at intervals along a straight line in the space, contacting the bottom of the saddle and supporting the saddle;
[0013] At least two sleeves are fitted together, one in a pair, onto the anchor bolt, with one end in contact with the bottom support, and the sleeves and the anchor bolts are inserted together into the waist-shaped slot on the saddle.
[0014] And at least two pads, one on each side of the other end of the sleeve, pressed together by the anchor bolts, with a gap A between them and the saddle for limiting the saddle.
[0015] Furthermore, the number of anchor bolts is two, symmetrically connected to the foundation.
[0016] Furthermore: the anchor bolt includes: a bolt body, one end of which is connected to the foundation and the bottom support, and the other end protruding from the waist-shaped groove and connected to the pad;
[0017] And two nuts, attached to the other end of the bolt body, press the washer down.
[0018] Furthermore: the bottom support is a square plate structure that fits onto the bolt body, with its bottom in contact with the foundation.
[0019] Furthermore, the stop is a square frame structure.
[0020] Furthermore, the space is a square space used to limit the roller.
[0021] Furthermore: the roller is a section of cylinder, the diameter of the roller is greater than the height of the stop, and the roller rolls along the space.
[0022] Furthermore: the number of sleeves is two, each sleeve being a section of round tube, which is fitted onto the bolt body and slidably connected to the waist-shaped groove.
[0023] Furthermore: the number of pads is two, the pads are square plate structures, and the side length B of the pads is greater than the width C of the waist-shaped groove.
[0024] Furthermore: the gap A is five millimeters.
[0025] The above technical solution has the following beneficial effects: A rolling support device suitable for boiler saddles, compared with related technologies, is provided with anchor bolts, bottom support, stop, roller, sleeve and pad.
[0026] Anchor bolts are symmetrically connected to the foundation. The bottom support is fitted onto the anchor bolts and connected to them. The bottom of the bottom support is in contact with the foundation, forming a reliable support structure. The stop is connected at the middle position of the top of the bottom support. There is a space between the stop and the bottom support. Rollers are arranged at intervals along a straight line in the space. A pair of sleeves are fitted onto the anchor bolts. A pair of pads are placed on the sleeves and pressed tightly by the anchor bolts.
[0027] During use, the bottom of the saddle contacts the roller, and the waist-shaped groove on the saddle slides in connection with the sleeve. When thermal expansion and contraction occur or an earthquake occurs, the boiler moves smoothly due to the rolling friction between the saddle and the roller, resulting in relatively low frictional resistance. This creates a buffer, effectively releasing the expansion. Furthermore, the waist-shaped groove and the sleeve form a guide, preventing the boiler from deviating from its direction when moving. At the same time, the blocking and limiting effect of the pad reduces the chance of the saddle coming off the sleeve and anchor bolts, thus reducing the chance of tipping over and making it relatively safe.
[0028] This overcomes the technical problem that the relatively large frictional resistance between the saddle and the foundation can lead to sliding difficulties, affecting the effective release of expansion and posing a safety hazard of tipping over. It achieves the technical effect of reducing the frictional resistance between the saddle and the foundation, releasing expansion more effectively, reducing the probability of tipping over, and providing a relatively safer result, thus demonstrating practicality.

[0034] To make the content easier to understand, the following detailed description is provided with reference to specific embodiments and accompanying drawings;
[0035] A rolling support device for boiler saddles solves the technical problem in related technologies where the relatively high frictional resistance between the saddle and the foundation leads to sliding difficulties, affecting the effective release of expansion and posing a safety hazard of tipping over. This device can be manufactured and used, achieving the positive effects of reducing the frictional resistance between the saddle and the foundation, improving the release of expansion, reducing the probability of tipping over, and ensuring relative safety. The overall concept is as follows:
[0036] Implementation
[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; a rolling support device suitable for boiler saddles, comprising:
[0038] At least two anchor bolts 10 are symmetrically connected to the foundation 100, with one end of each anchor bolt 10 connected to the foundation 100 and the other end protruding from the foundation 100.
[0039] The bottom support 20 is fitted onto the anchor bolt 10 and connected to the anchor bolt 10. Its bottom is in contact with the foundation 100, and the other end of the anchor bolt 10 protrudes from the bottom support 20.
[0040] A stop 30 is connected at the middle position of the top of the bottom support 20 and is spaced apart from the anchor bolt 10. There is a space 31 between the stop 30 and the bottom support 20.
[0041] Several rollers 40 are arranged at intervals along a straight line in the space 31, contacting the bottom of the saddle 200 and supporting the saddle 200.
[0042] At least two sleeves 50 are fitted together on the anchor bolt 10, with one end in contact with the bottom support 20, and the sleeves 50 and the anchor bolt 10 are inserted together into the waist-shaped slot 201 on the saddle 200;
[0043] And at least two pads 60, one to one, are placed on the other end of the sleeve 50, pressed by the anchor bolts 10, and have a gap A between them and the saddle 200 for limiting the saddle 200;
[0044] Specifically, during implementation, the bottom of the saddle 200 contacts the roller 40, and the waist-shaped groove 201 on the saddle 200 is slidably connected to the sleeve 50. When thermal expansion and contraction occur or an earthquake occurs, the boiler rolls and rubs against the roller 40 at the saddle 200, resulting in relatively low frictional resistance. The saddle 200 can move smoothly, forming a buffer and effectively releasing the expansion. Furthermore, the waist-shaped groove 201 and the sleeve 50 form a guide, preventing the boiler from deviating from its direction when moving. At the same time, the blocking and limiting effect of the pad 60 and the anchor bolt 10 reduces the probability of the saddle 200 detaching from the sleeve 50 and the anchor bolt 10, thus reducing the probability of tipping over and making it relatively safe.
[0045] Another implementation method:
[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; in practice, there are two anchor bolts 10, which are symmetrically connected to the foundation 100 to form a reliable support structure;
[0047] The anchor bolt 10 includes: a bolt body 10-1, one end of which is connected to the foundation 100 and the bottom support 20, and the other end protrudes from the waist-shaped groove 201 and is connected to the pad 60; and two nuts 10-2, which are connected to the other end of the bolt body 10-1 and press the pad 60.
[0048] The bolt body 10-1 and nut 10-2 are common structures in the prior art. One end of the bolt body 10-1 is inserted into the foundation 100 to form a reliable support structure. The nut 10-2 is a hexagonal nut used to limit the washer 60 and the sleeve 50.
[0049] Another implementation method:
[0050] like Figure 1 , Figure 2 , Figure 4 As shown; in implementation, the bottom support 20 is a square plate structure, which is fitted onto the bolt body 10-1. The bottom contacts the foundation 100, forming a reliable support structure, which is conducive to connecting the stop 30. After the space 31 is formed between the stop 30 and the stop 30, it is conducive to the roller 40 rolling along the space 31. The rolling is relatively smooth and there will be no jamming.
[0051] The stop 30 is a square frame structure. For example, the stop 30 is welded to the bottom support 20 to form a space 31. The space 31 is a square space used to limit the roller 40. When the roller 40 rolls along the space 31, the rolling is relatively smooth. Moreover, due to the obstruction of the stop 30, the roller 40 will not leave the space 31, and the structural reliability is relatively good.
[0052] Another implementation method:
[0053] like Figure 1 , Figure 2 , Figure 4 As shown; in practice, the roller 40 is a cylindrical section, and there are at least two of them, which are arranged at intervals along a straight line in the space 31 and can roll along the space 31.
[0054] The diameter of the roller 40 is larger than the height of the stop 30. This size control allows the roller 40 to contact the bottom of the saddle 200 and support the saddle 200, while the stop 30 does not contact the saddle 200. This allows the roller 40 to rotate and roll along the saddle 200, resulting in relatively low frictional resistance and enabling the saddle 200 to move smoothly.
[0055] Another implementation method:
[0056] like Figure 1 , Figure 2 , Figure 4 As shown; in practice, there are two sleeves 50, each sleeve 50 is a section of round tube, which is fitted onto the bolt body 10-1 and slidably connected to the waist-shaped groove 201;
[0057] The sleeve 50 and the waist-shaped groove 201 form a guide, which prevents the boiler from deviating from its direction when it moves, making it relatively safe.
[0058] Another implementation method:
[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; in practice, there are two pads 60. The pads 60 are square plate structures, and the side length B of the pads 60 is greater than the width C of the waist-shaped groove 201. The size control allows the pads 60 to form a block to prevent the saddle 200 from detaching from the sleeve 50 and the anchor bolt 10.
[0060] The gap A is five millimeters, so that the saddle 200 will not collide with or rub against the pad 60 when it moves, thus reducing frictional resistance.
[0061] Regarding the foundation 100, boiler, and saddle 200:
[0062] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The foundation 100, boiler and saddle 200 are common structures in the prior art. For example, the foundation 100 is made of reinforced concrete, the boiler is a horizontal boiler, and the saddle 200 is set on the bottom of the boiler. The saddle 200 has two waist-shaped slots 201.
[0063] In the existing technology, boilers are usually equipped with a fixed saddle and a movable saddle. The saddle refers to the supporting foot of the boiler. One saddle is fixed to the foundation by anchor bolts, while the other saddle is not fixed to the foundation. With the technical solution of this utility model, both saddles can also be set as movable saddles (the movable saddle refers to the bottom of the saddle 200 being equipped with "a rolling support device suitable for boiler saddles"). This not only enables the boiler to move smoothly through the rolling friction between the saddle 200 and the roller 40, forming a buffer and effectively releasing the expansion, but also reduces the probability of the saddle 200 detaching from the sleeve 50 and the anchor bolt 10 by blocking and limiting the movement, thus reducing the probability of tipping over and making it relatively safe.
