Description

Technical Field

[0001] The present application belongs to the technical field of steelmaking equipment maintenance, and specifically relates to a disassembly and assembly device. Background Art

[0002] The coiler plays a key role in the finishing of the finished coil in the cold-rolled automotive plate continuous annealing production line. The coiler coils the strip steel delivered from the process section into a coil, which is then transported out by the coil trolley. In recent years, due to the increase in different demands from order customers, there are different requirements for the coil core of the steel coil, which makes the sleeve replacement frequent.

[0003] At present, manual replacement of rubber sleeves is mostly adopted, and the operation needs to be completed with the assistance of a steel coil trolley. When replacing rubber sleeves, existing disassembly and assembly tools always fail to move in and out along the mandrel due to the influence of the sleeve's own weight, as well as the problem of thermal expansion and contraction of the sleeve caused by its service life and ambient temperature. Disassembly and assembly are inconvenient because the tools often get stuck or require external force. The replacement time is increased, or the replacement cannot be completed on time. The overall rhythm of the production line and the release of production capacity are affected, and the process cost is increased. Eventually, the furnace process is slowed down, thus affecting the normal production of the production line. Operators need to intervene with external force, which poses a great human safety hazard. Utility Model Content

[0004] The present application aims to at least to some extent solve the technical problems that the existing sleeves are always not inserted and removed along the core axis during disassembly and assembly, often get stuck or require artificial external force, and are inconvenient to disassemble and assemble. To this end, the present application provides a disassembly and assembly device.

[0005] The technical solution of this application is:

[0006] The present application provides a disassembly and assembly device, which is used for replacing a coiler sleeve, and the device comprises:

[0007] Drag rack;

[0008] A supporting mechanism, on which the drum frame is clamped;

[0009] The mobile saddle is provided with the support mechanism foldably in a central groove of the mobile saddle.

[0010] Furthermore, a mounting seat is provided at the bottom of the drum frame, and the mounting seat is clamped on the supporting mechanism.

[0011] Furthermore, the supporting mechanism comprises:

[0012] A base bracket, the mounting seat is clamped on the base bracket.

[0013] Furthermore, the base support is a rectangular parallelepiped structure with a length set at 5cm-10cm, a width set at 10cm-18cm, and a thickness set at 1cm-2cm.

[0014] Furthermore, a groove is provided on the upper portion of the base bracket, and the mounting seat is clamped in the groove.

[0015] Furthermore, the depth of the groove is set at 2cm-3cm.

[0016] Furthermore, the shape of the groove is consistent with the shape of the mounting seat, and the side length of the groove is 0.5 cm-1 cm larger than the corresponding side length of the mounting seat.

[0022] The present application provides a disassembly and assembly device with a simple structure, which is economical and practical. The disassembly and assembly device is installed on a steel coil trolley. After it is fixed, it is moved to the rear of the core shaft by the trolley. After the drum frame is in full contact with the sleeve, the trolley moves horizontally, and the drum frame can apply force accurately and move in and out along the direction of the core shaft, ultimately avoiding the problem of being unable to disassemble and assemble the sleeve normally, greatly reducing the need for operators to use external force to assist in intervention, and reducing the potential personal injury caused, as well as greatly reducing the replacement time, reducing the workload of personnel on duty, and ensuring the normal production of the production line.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Figure 1 A disassembly and assembly device according to an embodiment of the present application, combined with Figure 1 The disassembly and assembly device is used for replacing the coiler sleeve. The device includes a drum frame 1, a supporting mechanism and a movable saddle 2. The drum frame 1 is clamped on the supporting mechanism; the supporting mechanism is foldably arranged in the central groove of the movable saddle 2.

[0032] In some embodiments, a mounting seat 3 is disposed at the bottom of the drum frame 1 , and the mounting seat 3 is clamped on the supporting mechanism.

[0033] In some embodiments, the main difference between different sleeve specifications is the outer diameter. The arc of the sleeve support frame is mainly to adapt to sleeves of different specifications, ensuring that sleeves of different diameters can be supported by the sleeve frame and easily replaced. The arc angle of the sleeve support frame 1 is 160°-180°.

[0034] In some embodiments, the support mechanism includes: a base bracket 4, and the mounting seat 3 is clamped on the base bracket 4. The base bracket 4 is a rectangular parallelepiped structure, with a length of 5cm-10cm, a width of 10cm-18cm, and a thickness of 1cm-2cm. In order to better adapt to the actual size of the mobile saddle 2 on site, the small size of the structure is ensured on the basis of ensuring a good supporting structure and a certain force-bearing capacity, so as to facilitate quick installation by personnel.

[0035] In some embodiments, a groove is provided on the upper portion of the base bracket 4, and the mounting seat 3 is clamped in the groove. The depth of the groove is set at 2cm-3cm. If the depth is too small, it is not easy to fix and the sleeve is easily scratched due to poor force during use. If the depth is too deep, it is not easy for personnel to install. Controlling the depth to 2cm-3cm can satisfy the sleeve rack on the basis of having a certain force bearing capacity, and it can also facilitate personnel to quickly install.

[0036] The equipment specifications of the mobile saddle 2 are relatively fixed, and the middle groove part does not change due to the replacement of the saddle, so it has a certain reference and invariance. In some embodiments, in order to use on-site equipment to assist personnel in quickly installing the sleeve, the shape of the groove is consistent with the shape of the mounting seat 3, and the side length of the groove is 0.5cm-1cm larger than the corresponding side length of the mounting seat 3.

[0037] In some embodiments, the support mechanism further includes a sliding bracket 5 , one end of which is hinged to the base bracket 4 .

[0038] Specifically, the sliding bracket 5 is a trapezoidal plate, and the upper bottom of the sliding bracket 5 is hinged to the base bracket 4. In the embodiment of the present application, the sliding bracket 5 is connected to the base bracket 4 by a hinge, and can also be movably connected by other means such as hinges, which are not specifically limited here. When in use, the other end of the sliding bracket 5 can be supported in the central groove of the mobile saddle 2.

[0039] When using the disassembly and assembly device provided in the embodiment of the present application to disassemble and assemble the coiler sleeve, first install the disassembly and assembly device on the steel coil trolley. After it is fixed, first lift the base bracket 4, and the lower bottom of the sliding bracket 5 is supported in the middle groove of the movable saddle 2. The base bracket 4 is erected through the sliding bracket 5, and then the barrel support frame is clamped with the base bracket 4, and the sleeve is placed on the barrel support frame. The principle that the center of gravity of the sleeve and the center of gravity of the barrel support frame are in a straight line is used to complete the fixing of the sleeve, and then the moving function of the movable saddle 2 is used to send the sleeve to the specified position, and then the barrel support frame is removed, and the base bracket 4 is placed flat in the middle groove of the movable saddle 2 using the sliding bracket 5.

[0040] The embodiments of the present application have at least the following beneficial effects:

[0041] 1. The present application can reduce manpower by cooperating with the movable saddle and the base bracket, and utilize the movable characteristics of the movable saddle to complete the installation of the sleeve.

[0042] 2. The present application uses a hinge connection between the sliding bracket and the base bracket, so that the base bracket can be directly placed in the middle slot of the movable saddle, which does not affect other functions of the movable saddle and reduces the preparation time for sleeve installation.

[0043] 3. The present application designs the sliding bracket as a trapezoidal plate, which has a simple structure, good support, and a bottom that fits closely with the groove of the mobile saddle, making full use of the existing saddle equipment to assist personnel in replacing the sleeve.
