Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for boiler construction, and in particular to a rigid rod auxiliary docking device. Background Technology

[0002] Thermal power has long held a dominant position in China's energy structure. Boilers are one of the core pieces of equipment in this industry. Their function is to generate high-temperature flue gas from the combustion of internal combustion materials such as coal, which heats water inside the boiler, causing it to evaporate into steam. The steam then passes through components such as heat exchangers and reheaters, where it is heated and pressurized to drive a steam turbine, ultimately rotating a generator to produce electricity. With the continuous growth in electricity demand in recent years, the scale of the thermal power generation industry has also been expanding, with more and more megawatt-class boilers being built and put into use.

[0003] The main body of the boiler heating surface mentioned above all adopts a fully suspended structure, that is, a large number of rigid hangers are set between the plate beam support layer and the main body of the boiler heating surface to bear the static and dynamic loads of the entire boiler. Due to the huge size of this type of boiler, the hangers used are relatively long. The length of the hangers is limited by processing, manufacturing and transportation conditions. Therefore, when using them, multiple hangers need to be connected in sequence using turnbuckles or similar materials to increase their length before being moved to the boiler construction site for installation. Moreover, the above connection work needs to be completed on the boiler construction site to solve the problem of long-distance transportation of long hangers.

[0004] When connecting booms, due to their large length and weight, hoisting equipment is required. During the connection process, the booms also need to be rotated in a timely manner. However, when the booms are in a hoisted state, they lack effective support, making them prone to swaying and unstable. Rotating the booms will exacerbate the swaying, resulting in uneven stress on the contact surfaces of the booms, which can easily cause damage and lead to low connection efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a rigid rod auxiliary docking device that provides stable support, facilitates docking operations, and helps improve work efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a rigid rod auxiliary docking device, including a support beam, at least two support bases are fixedly installed on the top of the support beam, and a rod support rolling device is respectively assembled on each support base. The rigid rod is placed along the length direction of the support beam and supported on the top of the two rod support rolling devices. A lifting hook device is arranged and installed on the side of the support beam or the side of each support base.

[0007] As a preferred technical solution, the rod support rolling device includes two support shafts arranged along the length of the support beam. The two support shafts are fixedly welded to the top of the support base in parallel. Rollers are rotatably mounted on each support shaft, and the rigid rod is placed between the two rollers.

[0008] As a preferred technical solution, a bottom clearance space is formed between the two rollers to increase the stability of the rigid rod placement.

[0009] As a preferred technical solution, the support base includes two support channel steels that span the support beam and are arranged opposite to each other, and a roller clearance space is formed between the two support channel steels to accommodate the bottom of the roller.

[0010] As a preferred technical solution, the lifting hook device is provided in four sets and fixed on the supporting crossbeam, and the four sets of lifting hook devices are arranged opposite to each other on both sides of the supporting crossbeam.

[0011] As a preferred technical solution, the hoisting hook device includes a hoisting hook lug plate extending outward from the side wall of the supporting beam, and a hook hole is provided through the hoisting hook lug plate.

[0012] As an improvement to the above technical solution, the supporting beam is set as an I-beam.

[0013] Due to the adoption of the above technical solution, the rigid boom auxiliary docking device includes a support beam. At least two support bases are fixedly installed on the top of the support beam, and a boom support rolling device is respectively assembled on each support base. The rigid boom is placed along the length of the support beam and supported on the top of the two boom support rolling devices. A lifting hook device is arranged and installed on the side of the support beam or the side of each support base. This utility model has the following beneficial effects: In use, the rigid boom is placed on the top of each boom support rolling device, and the hook of the lifting equipment, such as an electric hoist, is hooked on each lifting hook device. After starting the lifting equipment and moving the rigid boom to the docking point, its lifting state is released so that it can be screwed to the turnbuckle on another rigid boom. During the screwing process, the rigid boom on this device can be rotated. During the screwing process, the support of the rigid boom is stable and will not sway from side to side, thereby eliminating the contact and uneven force between the screwed ends. Moreover, under the action of the boom support rolling device, the rigid boom can be rotated easily, which helps to improve its docking efficiency. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0016] The long-length rigid booms used in thermal power plant boilers are formed by connecting at least two rigid boom sections 1. One end of each rigid boom section 1 is equipped with a turnbuckle nut 2 for connection, and the other end has a connecting thread. The turnbuckle nut 2 enables the threaded connection of the two rigid boom sections 1, making the connection simple and convenient. It is evident that when connecting the two rigid boom sections 1, at least one of the rigid boom sections 1 needs to be rotated. The rigid boom 1 auxiliary connection device in this embodiment is used for lifting and loading, threaded support, and easy rotation of one of the rigid boom sections 1.

[0017] like Figures 1 to 3 As shown, the rigid suspension rod auxiliary docking device includes a support beam 3. At least two support bases are fixedly installed on the top of the support beam 3. The support base includes two support channel steels 4 that span the support beam 3 and are arranged opposite each other. The support beam 3 is set as an I-beam. The support beam 3 and the support base are easy to obtain materials on-site at the boiler construction site. In particular, the support channel steels 4 have a short length and can be reused as scraps, which makes the processing cost of the whole device low.

[0018] Each of the aforementioned support bases is respectively equipped with a corresponding boom support rolling device, and a lifting hook device is arranged and installed on the side of the support beam 3 or the side of each of the aforementioned support bases. The rigid boom 1 is placed along the length of the support beam 3 and supported on the top of the two boom support rolling devices. By using lifting equipment such as an electric hoist to hook onto each of the aforementioned lifting hook devices, the rigid boom 1 can be lifted and easily moved to the docking position.

[0019] Specifically, the boom support rolling device includes two support shafts 5 arranged along the length of the support beam 3. The two support shafts 5 are fixedly welded to the top of the support base in parallel. Rollers 6 are rotatably mounted on each support shaft 5. The rigid boom 1 is placed between the two rollers 6, so that the two rollers 6 and the rigid boom 1 form an approximately point contact, with a small contact area, resulting in less wear on the surface of the rigid boom 1. Furthermore, a bottom clearance space 7 is formed between the two rollers 6 to increase the stability of the rigid boom 1. The bottom clearance space 7 increases the distance between the contact points of the two sides of the rigid boom 1 and the rollers 6, which helps to improve its stability when placed between the two rollers 6, prevents it from rolling off during lifting, and makes it safer and more reliable to use. A roller clearance space 8 is formed between the two support channel steels 4 to accommodate the bottom of the rollers 6, ensuring that the rollers 6 can be smoothly assembled and rolled.

[0020] In this embodiment, four sets of lifting hook devices are provided and fixed on the support beam 3. The four sets of lifting hook devices are arranged opposite to each other on both sides of the support beam 3. When the device is lifted by lifting equipment, the force is more even, which helps to maintain the stability of the lifting.

[0021] The hoisting hook device includes a hoisting hook lug 9 extending outward from the side wall of the supporting beam 3, and a hook hole 10 passing through the hoisting hook lug 9. The hook on the hoisting equipment can be detachably hooked into the hook hole 10.

[0022] like Figure 4As shown, in use, one section of the rigid rod 1 is placed on an auxiliary device 11 such as a support platform or support frame at the same height as the device. At least two brackets 12 can be arranged and installed on the auxiliary device 11, so that the top of the bracket 12 forms an arc groove covering the bottom of the rigid rod 1, providing stable support for the rigid rod 1 placed on top of it. The other rigid rod 1 is placed on each of the rollers 6 of the device. With the help of the hoisting equipment and the hoisting hook lug 9, the device is moved to the side of the auxiliary device 11 such as the support platform or support frame. After adjusting the two sections of the rigid rod 1 to be coaxial, the support beam 3 is lowered, and the rigid rod 1 on the device is pushed so that the threaded end of it engages with the turnbuckle nut 2. By rotating the rigid rod 1 on the device, the connection between it and the turnbuckle nut 2 can be gradually achieved. When rotating the rigid rod 1 on this device, the rolling engagement of the roller 6 results in low rotational resistance, making operation convenient and labor-saving, which helps to improve the screw connection efficiency. Furthermore, during the docking process of the two sections of the rigid rod 1, both can be stably supported, with virtually no collision at their ends and minimal damage.

[0023] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
