Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of manufacturing tube box structure products, and in particular to an auxiliary device for installing tube box serpentine segments. Background Technology
[0002] In waste incinerator products, the economizer is generally a tube box structure. In some overseas projects, the superheater is also a tube box structure, mainly composed of serpentine tubes, inlet and outlet headers, tube box shell consisting of four side walls, and top hanging beams.
[0003] During the installation of the serpentine tube segments, the top hanging beam and three side walls were already in place, leaving only one side and bottom space for hoisting the segments. Due to the presence of the top hanging beam, it was impossible to use an overhead crane to hoist the segments into place in one go. In actual installation, an overhead crane was used to lift the serpentine segments to the side of the tube box where the side walls were not installed. Then, another overhead crane was used to assist, bypassing the top hanging beam, and slowly inserting the segments into the tube box for hoisting and positioning, and securing them to the hanging beam. Because two overhead cranes were required for hoisting, the efficiency of segment installation was low. Furthermore, each economizer tube box required the installation of a large number of serpentine segments, significantly increasing the number of times the overhead cranes had to work together and the time spent on installation. As the segments were installed, the space inside the tube box decreased, gradually increasing the difficulty of hoisting by the overhead cranes and further reducing efficiency. At the same time, the prolonged occupation of two overhead cranes also affected the use of overhead cranes by other products in the workshop, reducing the overall manufacturing efficiency of the workshop.
[0004] Therefore, during the installation process, it is of great significance to consider how to reduce the use of overhead cranes, lower the difficulty of segment installation, and improve installation efficiency. For this reason, designing an auxiliary device for the installation of serpentine segments in a tube box is essential. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model designs an auxiliary device for the installation of tube box-type serpentine segments.
[0006] The present invention adopts the following technical solution:
[0007] An auxiliary device for installing serpentine segments in a tube box includes a bottom frame with rollers installed at the four corners of the bottom of the bottom frame. Long limiting rods and short limiting rods are fixedly installed at the middle positions on both sides of the bottom frame, respectively. The two long limiting rods and the short limiting rods are arranged side by side, forming a limiting and placement groove for the serpentine segments between the long limiting rods and the short limiting rods.
[0008] Preferably, the bottoms of the long and short limiting rods are welded to the bottom frame. They provide limiting and partial support for the serpentine tube segments. The use of the short limiting rod reduces the difficulty of placing the serpentine tube segments into the device. The long and short limiting rods protrude from the entire device and are spaced relatively close together, reducing space requirements during use.
[0009] Preferably, the bottom frame consists of four H-beams, which serve to bear loads and provide support.
[0010] Preferably, the long limiting rod and the short limiting rod are supported by diagonal braces on both sides, with one end of the diagonal brace welded to the long limiting rod or the short limiting rod, and the other end welded to the bottom frame.
[0011] Preferably, a horizontal brace is welded between the diagonal brace and the long limiting rod, as well as between the diagonal brace and the short limiting rod. The diagonal brace and the horizontal brace provide support and reinforcement for the limiting rod.
[0012] Preferably, the rollers are casters, which serve to move the entire device.
[0013] The beneficial effects of this utility model are: the structure of this utility model is simple and reasonable, and the device can be used for the auxiliary installation of serpentine segments of various specifications in the pipe box; the device can move the serpentine segments to the direct below the required installation position in one go, which can greatly reduce the frequency and time of use of the crane and reduce the difficulty of hoisting the serpentine segments.

[0018] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0019] Example: Figure 1As shown, an auxiliary device for installing serpentine segments in a tube box configuration includes a bottom frame 1, long limiting rods 2, short limiting rods 3, diagonal braces 4, horizontal braces 5, and casters 6. Casters are installed at the four corners of the bottom of the bottom frame. Long limiting rods and short limiting rods are welded to the middle positions of both sides of the bottom frame, respectively. The two long limiting rods and the short limiting rods are arranged side by side, forming a limiting and placement groove for the serpentine segments between them.
[0020] The main frame consists of four H-beams. Diagonal braces support both sides of the long and short limiting rods, with one end welded to either the long or short limiting rod and the other end welded to the bottom frame. Horizontal braces are welded between the diagonal braces and the long limiting rods, as well as between the diagonal braces and the short limiting rods.
[0021] like Figure 2 As shown, an auxiliary device and working object for installing a tube box type serpentine tube segment are disclosed. The working object, the serpentine tube segment 7, is placed between the two long limiting rods 2 and short limiting rods 3 on both sides. The lower end of the serpentine tube segment 7 stands on the bottom frame 1, and the middle and upper sides lean against the long limiting rods 2 or the short limiting rods 3.
[0022] like Figure 3 As shown, an auxiliary device for installing serpentine segments in a tube box is actually applied in operation. The serpentine segment 7 to be installed is placed on the auxiliary device. By moving the device, the serpentine segment 7 is transported to the inside of the tube box housing 8, below the top hanging beam 9. During the installation operation, the tube box housing is placed on the tooling stool 10 for installation.
[0023] In actual operation, a crane is used to lift the serpentine segment 7, and the crane is controlled to move the serpentine segment 7 until its lower end passes the short limiting rod 3 and rests against the long limiting rod 2. The serpentine segment 7 is then lowered and inserted between the two limiting rods. An auxiliary device for installing serpentine segments in a tube box is moved to transport the serpentine segment 7 to below the top hanging beam 9 for installation. When a large number of serpentine segments 7 have been installed in the tube box shell 8, the long limiting rod 2 and the short limiting rod 3 of the device need to be aligned with the gaps between the installed serpentine segments 7, and the serpentine segment 7 to be installed is transported into place.
[0024] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
