Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary protective equipment for the installation of serpentine tube banks in boilers, and in particular to a protective device for serpentine tube banks in boilers. Background Technology

[0002] The upper part of the boiler furnace is equipped with serpentine tube banks, which are generally used in large quantities and arranged in upper and lower layers within the furnace. Due to the large size of the boiler, the serpentine tube banks used are also large in size and weight. In addition, their installation position is high, so their installation cannot be completed manually and requires hoisting equipment such as winches and overhead cranes. When installing serpentine tube banks in the boiler, the upper serpentine tube banks must be installed and fixed first, and then the lower serpentine tube banks are installed one by one. In this way, the hoisting steel rope of the hoisting equipment must pass through the gaps between the previously installed serpentine tube banks. In addition, since the hoisting steel rope has no guiding or supporting components, it will sway back and forth under the weight of the serpentine tube banks during hoisting, and it is easy for it to come into contact with the serpentine tube banks on both sides of the gaps, causing serious wear on the surface of the serpentine tube banks, thus affecting their service life. Furthermore, the gaps between the upper serpentine tube banks after installation are very small, making it difficult to maintain, repair or replace the worn serpentine tube banks.

[0017] 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.

[0018] like Figures 1 to 5 As shown, the protective device for the serpentine tube bank inside the boiler is used to limit the hanging between two adjacent serpentine tube banks 1. During the installation of the serpentine tube bank 1 inside the boiler, when hoisting and installing the lower layer of the serpentine tube bank 1, it plays a role in preventing wear and tear on the upper layer of the serpentine tube bank 1 that has already been installed, thereby ensuring the installation quality and service life of the serpentine tube bank 1.

[0019] This embodiment includes two protective panels for pipe rows arranged opposite each other. In use, the two protective panels are respectively located inside the corresponding two serpentine pipe rows 1, that is, between two adjacent serpentine pipe rows 1. A lifting gap 2 is formed between the two protective panels. When the serpentine pipe row 1 is lifted, the lifting steel rope 3 on the lifting equipment passes through the lifting gap 2. Due to the arrangement of the two protective panels, the lifting steel rope 3 will not come into contact with the surface of the serpentine pipe row 1 when it sways, thereby providing wear-resistant and collision-resistant protection for the serpentine pipe row 1.

[0020] A panel connecting beam group is fixedly connected between the two pipe bank protective panels, and each panel connecting beam group is provided with at least two parallel panel connecting beams 4. The panel connecting beams 4 connect the two pipe bank protective panels into an integrated structure, and at the same time form a limit on the side of the hoisting steel rope 3. In cooperation with the two pipe bank protective panels, the hoisting steel rope 3 is surrounded in the hoisting gap 2, thereby improving the protective effect on the serpentine pipe bank 1.

[0021] Each of the pipe bank protective panels is fixedly connected to a protective panel hook 5 at its top end, and the mounting opening of the protective panel hook 5 is located on the outside of the pipe bank protective panel. The entire device is mounted to the two adjacent serpentine pipe banks 1 through the protective panel hook 5, thus confining the entire device between the two adjacent serpentine pipe banks 1.

[0022] In this embodiment, the pipe bank protective panel includes two parallel protective panel beams 6, with a protective panel body 7 fixedly connected between the two protective panel beams 6. Each protective panel beam 6 has a corresponding protective panel hook 5 fixedly installed at its top. Thus, the entire device forms four hook points with the serpentine pipe bank 1, making the installation of the entire device safer and more reliable. To avoid adverse effects on the serpentine pipe bank 1 when using the protective panel beams 6 and the protective panel hooks 5, a rubber layer can be provided on the surface of the protective panel beams 6 and the protective panel hooks 5 for cushioning protection.

[0023] A reinforcing crossbeam 8 is arranged and connected between the two protective panel upright beams 6 to enhance the strength of the entire pipe row protective panel. The protective panel upright beams 6 and the reinforcing crossbeam 8 are respectively set as hollow tubes, which can reduce the weight of the entire device and facilitate use. The protective panel body 7 is made of steel plate or mesh plate, especially when it is made of mesh plate, it can further reduce weight.

[0024] 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.
