Abstract
Description
Technical Field
[0001] This utility model is applied in the field of sintering machine maintenance technology, and in particular relates to an auxiliary tooling for the maintenance of the sealing skin of a sintering trolley. Background Technology
[0002] Flexible sealing skin for sintering machines is a sealing material installed between the sintering machine trolley and the air box, or other parts requiring sealing. It utilizes the negative pressure created by the airflow from the air box to adhere the flexible sealing skin to the corresponding sealing surfaces, thus achieving a seal. Currently, most companies are promoting its use as a replacement for traditional mechanical seals.
[0003] In practice, after the sintering trolley has been in operation for a period of time, the flexible sealing skin will be inspected regularly to check whether the flexible sealing skin has been locally worn or damaged under high temperature and mechanical friction, so as to avoid the problem of air leakage due to poor sealing between the sintering trolley and the air box.
[0004] In current maintenance procedures, if wear is found on the sealing skin corresponding to a sintering trolley, the trolley is usually lifted out by a crane. The maintenance worker then cuts off the worn part of the sealing skin with a cutting knife and then glues a good sealing skin to the worn area. This method results in an uneven cut surface of the sealing skin. After the new sealing skin is glued to the worn area, the uneven cut surface can easily cause air leakage at the bonding point. At the same time, the replacement sealing skin and the original sealing skin may not fit together properly, which can also cause secondary damage to the sintering trolley due to scraping. Utility Model Content
[0005] The purpose of this utility model is to provide an auxiliary tooling for the maintenance of the sealing skin of the sintering trolley, which solves the problems of uneven cutting surfaces, easy air leakage at the bonding position, and secondary damage caused by scratches of the sintering trolley.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] This utility model provides an auxiliary tooling for repairing the sealing skin of a sintering trolley, including a worktable, and further comprising:
[0008] The clamps are provided in at least two, and the at least two clamps are longitudinally distributed along the height direction. The clamp at the lowest end is installed on the workbench. One side of each clamp along the length direction is inclined, and the inclined surfaces of two adjacent clamps are located on the same plane.
[0009] The fasteners are provided with a plurality of fasteners distributed circumferentially along the clamping plate. The fasteners include a lead screw and a fastening nut threaded onto the lead screw. The bottom end of the lead screw is vertically fixed to the upper surface of the clamping plate at the lowest layer, and the top end of the lead screw slides upward to the top of the clamping plate at the highest layer.
[0010] Furthermore, a spring is provided on the lead screw at a position between two adjacent clamping plates.
[0011] Furthermore, a friction layer is provided on the outer surface of the clamping plate.
[0012] Furthermore, the clamping plate is provided with two guide blocks on the upper surface of one end of the inclined surface.

The two guide blocks are located on both sides of the upper surface of the clamping plate in the width direction.
[0013] Furthermore, the number of clamps is three.
[0014] Furthermore, the number of clamps is two.
[0015] Furthermore, the other side of the two clamping plates along the length direction is also inclined, and the inclined surfaces of two adjacent clamping plates are also located on the same plane.

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0030] Example 1
[0031] refer to Figures 1-4 This example provides an auxiliary tooling for the maintenance of the sealing skin of a sintering trolley. It is used to clamp and position the sealing skin 1 of the sintering trolley to be cut, thereby facilitating the subsequent cutting by the cutting blade.
[0032] Specifically, refer to Figures 1-4 The auxiliary tooling includes a workbench 2, clamping plates 3, and fasteners 4. There are at least two clamping plates 3, and in this example, there are three clamping plates 3. The three clamping plates 3 are distributed longitudinally along the height direction. The clamping plate 3 at the lowest end is installed on the workbench 2. Each clamping plate 3 has one side with an inclined surface 5 along its length direction. The inclined surface 5 has an inclination angle of 45°. The inclined surfaces 5 of the three clamping plates 3 are located on the same plane. There are multiple fasteners 4. In this example, there are four fasteners 4 and they are distributed at the four corners of the top clamping plate 3. The fasteners 4 include a lead screw 41 and a fastening nut 42 threaded onto the lead screw 41. The bottom end of the lead screw 41 is vertically fixed to the upper end face of the lowest clamping plate 3. The top end of the lead screw 41 slides upward and extends above the top clamping plate 3. The fastening nut 42 is located above the top clamping plate 3.
[0033] refer to Figures 1-4The working principle is as follows: When repairing or replacing a worn section 8 on the sealing skin 1, the sealing skin 1 is first cut in the middle of the worn part using a cutting blade, thus dividing it into two parts. The cut end of the sealing skin 1 on the left side passes between the top layer clamping plate 3 and the middle layer clamping plate 3 until the connection between the worn and unworn parts of the sealing skin 1 is located at the inclined surface 5 of the middle layer clamping plate 3. Similarly, the cut end of the sealing skin 1 on the right side passes between the middle layer clamping plate 3 and the bottom layer clamping plate 3 until the connection between the worn and unworn parts of the sealing skin 1 is located at the bottom layer clamping plate 3. At the inclined surface 5 of the clamping plate 3, a downward pressure is applied to the clamping plate 3 by tightening the fastening nut 42, bringing the top clamping plate 3 and the middle clamping plate 3 closer to the bottom clamping plate 3, thereby clamping and fixing the sealing skin 1. The on-site worker holds a cutting knife and cuts along the inclined surface 5 of the clamping plate 2 to remove the worn part of the sealing skin 1. The cut surface of the sealing skin 1 is inclined, which facilitates the subsequent adhesive fixing to the good sealing skin 1. In addition, this auxiliary tool can also cut the spare sealing skin for repair. The two ends of the cut sealing skin are also set with inclined surfaces (see reference). Figure 4 It is easy to bond.
[0034] refer to Figures 1-4 A spring 6 is installed on the lead screw 41, positioned between two adjacent clamping plates 3. The spring 6, under its supporting force, spreads the two adjacent clamping plates 3 apart, facilitating the feeding of the sealing skin 1. The thickness of the compressed spring 6 is less than the thickness of the sealing skin 1, ensuring that the clamping plates 3 can adhere to the sealing skin 1 after tightening. A friction layer (not shown in the figure) is provided on the outer surface of the clamping plates 3, which increases the friction between the clamping plates 3 and the sealing skin 1, resulting in a more secure fixation.
[0035] refer to Figures 1-4 Two guide blocks 7 are provided on the upper surface of one end of the clamping plate 3, which is an inclined surface. The side of the guide blocks 7 near the inclined surface 5 is also inclined, and the inclination angle of the inclined surface of the guide blocks 7 is the same as that of the inclined surface 5 of the clamping plate 3 and they are located on the same plane. The two guide blocks 7 are located on both sides of the upper surface of the clamping plate 3 in the width direction. When the sealing skin is cut by the cutting knife, the cutting knife moves down along the inclined surface of the guide blocks 7, which can further improve the flatness of the cut surface of the sealing skin 1.
[0036] In summary, this auxiliary tooling effectively secures the seal 1 to be repaired. Furthermore, when cutting the seal 1 with the cutting tool, a relatively flat, angled surface can be directly cut, facilitating subsequent adhesive bonding. This makes the operation convenient and quick, improving repair efficiency. The repaired seal 1 exhibits a smooth, firm bond at the bonding points, preventing air leakage. The smooth surface of the repaired seal also prevents secondary damage from scratches during the sintering trolley's operation.
[0037] Example 2
[0038] The content of this example is basically the same as that of Example 1, except that:
[0039] refer to Figure 5 and Figure 6 There are two clamping plates 3, and the other side of the two clamping plates 3 along the length direction is also set as an inclined surface 5, and the inclined surfaces 5 of the two adjacent clamping plates 3 are also located on the same plane. When the auxiliary tooling of this structure is working, after the worn sealing skin is divided into two, the two sealing skins 1 after the initial cut are fixed and cut in two stages by this auxiliary device, which can also remove the worn sealing skin, and the cutting surface is also inclined.
[0040] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model.
