Technical Field

[0001] The present application belongs to the technical field of disassembly devices, and in particular, relates to a disassembly device. Background Art

[0002] Unwinders and coilers are one of the most commonly used spare parts in the cold rolling area. There are many coilers in the cold rolling area. The wire is often broken due to the mandrel jumping, and therefore it is necessary to replace the fasteners used to connect the mandrel and the shaft cap buckled on one end of the mandrel. When replacing the fasteners of the shaft cap, it is also necessary to separate the shaft cap and the mandrel, and then reconnect the mandrel and the shaft cap after replacing the fasteners.

[0003] At present, for shaft caps with larger specifications, the shaft caps and the core shaft gradually separate during the process of disassembling multiple fasteners connecting the shaft caps and the core shaft. Due to the large mass of the shaft caps, the shaft caps are prone to shaking during disassembly. If not handled properly, the shaft caps may fall into the pit and cause damage to the equipment, affecting the disassembly and assembly efficiency of the shaft caps and posing safety issues. Utility Model Content

[0004] The present application aims to at least to some extent solve the technical problem that the disassembly and assembly efficiency is affected and there are safety issues during the disassembly and assembly process of the mandrel and the shaft cap. To this end, the present application provides a disassembly and assembly device.

[0005] An embodiment of the present application provides a disassembly and assembly device, which is used for disassembling and assembling a shaft cap, and the disassembly and assembly device includes:

[0006] The trolley comprises a base, a support platform which can be raised and lowered relative to the base, and rollers arranged on the base;

[0007] A mounting seat, arranged on the supporting platform;

[0008] At least two columnar support members are arranged side by side and spaced apart from each other on the mounting seat, two adjacent support members are used to support the shaft cap, and the axial direction of the support member is used to be parallel to the central axis direction of the shaft cap.

[0009] In some or certain embodiments, the mounting seat is a frame-shaped structure in which a frame-shaped hole extends along the normal direction of the surface of the support platform, and the length of the support member is less than or equal to the width of the mounting seat.

[0010] In some or certain embodiments, there is a gap between the support member and both ends or both sides of the mounting seat, and the radial direction of the support member extends along the axial direction of the mounting seat.

[0011] In some or certain embodiments, the support member is disposed on the mounting seat in an axial direction parallel to the surface of the support platform, and in a direction from the mounting seat to the support member, an area of ​​a longitudinal section of the support member decreases.

[0012] In some or certain embodiments, the support member is a triangular prism, and one side surface of the support member is closely connected to the mounting seat.

[0013] In some or certain embodiments, the disassembly and assembly device further includes a magnetic attraction component, which is disposed on the mounting seat and spaced apart from the support component along the axial direction of the support component.

[0014] In some or certain embodiments, the disassembly and assembly device further includes a fixing block, and both ends of the support member are respectively connected to the mounting seat via one of the fixing blocks.

[0015] In some or certain embodiments, the support member and the fixing block are integrally formed.

[0016] In some or certain embodiments, the support platform comprises:

[0017] The platform body can be raised and lowered relative to the base;

[0018] The saddle is connected to the platform body, and the mounting seat is sleeved and supported on the saddle.

[0019] In some or certain embodiments, the disassembly and assembly device further comprises:

[0020] a support plate connected to the platform body and spaced apart from the saddle;

[0021] A tightening column passes through the support plate and is threadably matched with the support plate, and one end of the tightening column is configured as a tightening end opposite to the mounting seat.

[0022] Advantageous effects provided by one or more embodiments of the present application:

[0023] The trolley can provide a mobile function, and the support platform of the trolley can be raised and lowered relative to the base of the trolley, so that the trolley has both lifting and moving functions. The mounting seat supported on the support platform can provide an installation space for the support member, and at least two columnar support members are arranged side by side and spaced apart from each other on the mounting seat. The support member itself can have a certain height relative to the mounting seat, and there is a certain relatively regular space between two adjacent support members. The shaft cap is supported on two adjacent support members and the axial direction of the shaft cap can extend along the axial direction of the support member. The lowest point of the shaft cap will naturally fall to the space between the two support members, and the two adjacent support members will support the peripheral wall of the shaft cap, stably limiting the position of the shaft cap between the two support members, and the position of the shaft cap can be effectively fixed. When the shaft cap and the mandrel need to be separated, the trolley is moved to a position close to the shaft cap, and the support platform is raised and lowered to raise and lower the mounting seat and the support member until two adjacent support members are supported on the peripheral wall of the shaft cap. During the separation of the shaft cap and the mandrel, the shaft cap can be effectively supported and fixed, and there is no need to frequently adjust the position of the shaft cap, which is conducive to shortening the disassembly and assembly time to improve the disassembly and assembly efficiency. Moreover, the shaft cap is supported by the support member and the trolley, and is not prone to falling and damage, which is conducive to improving the safety during the disassembly of the shaft cap. Finally, after the fasteners between the shaft cap and the mandrel are disassembled, the trolley can be moved to separate the shaft cap and the mandrel. Since the axial direction of the support member can extend along the direction of the central axis of the shaft cap and the trolley can be moved, the shaft cap and the mandrel are not prone to collision when separating the shaft cap and the mandrel, which is also conducive to improving the safety during the disassembly of the shaft cap, and to a certain extent solves the problem that the disassembly and assembly efficiency is affected and there is a safety problem during the disassembly of the mandrel and the shaft cap.

DETAILED DESCRIPTION

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

[0029] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0032] For ease of understanding, the wire breakage problem is explained here. If there is a certain error in the assembly of the mandrel of the coiler or uncoiler or if there is a problem with lubrication, it is easy to have a large runout, causing the fasteners connecting the mandrel and the shaft cap to break, resulting in wire breakage, and the fasteners need to be replaced.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Figure 1 A schematic diagram showing a disassembly and assembly device in use in some or certain embodiments of the present application is shown. Figure 2 A schematic diagram showing the matching relationship between a mounting seat and a support member in some or certain embodiments of the present application is shown, with reference to Figure 1 and Figure 2 The embodiment of the present application provides a disassembly and assembly device, which is used for disassembly and assembly of the shaft cap 100, and the disassembly and assembly device includes:

[0035] The trolley 1 comprises a base 11 , a support platform 12 which can be raised and lowered relative to the base 11 , and rollers 13 arranged on the base 11 .

[0036] The mounting seat 2 is arranged on the supporting platform 12 .

[0037] At least two columnar support members 3 are arranged side by side and spaced apart from each other on the mounting seat 2 . Two adjacent support members 3 are used to support the shaft cap 100 . The axial direction B of the support member 3 is used to be parallel to the central axis direction of the shaft cap 100 .

[0038] The trolley 1 can provide a moving function through the roller 13 connected to the base 11 in a rolling manner. The support platform 12 of the trolley 1 can be raised and lowered relative to the base 11 of the trolley 1, so that the trolley 1 has both the lifting and moving functions. The mounting seat 2 supported on the support platform 12 can provide an installation space for the support member 3, and at least two columnar support members 3 are arranged side by side and spaced from each other on the mounting seat 2. Then the support member 3 itself can have a certain height relative to the mounting seat 2, and there is a certain relatively regular space between two adjacent support members 3. The shaft cap 100 is supported on two adjacent support members 3 and the axial direction of the shaft cap 100 can extend along the axial direction B of the support member 3. The lowest point of the shaft cap 100 will naturally fall to the space between the two support members 3, and the two adjacent support members 3 will support the peripheral wall of the shaft cap 100, and the position of the shaft cap 100 is stably limited between the two support members 3, and the position of the shaft cap 100 can be effectively fixed. When it is necessary to separate the shaft cap 100 and the core shaft 200, the trolley 1 is moved to a position close to the shaft cap 100, and the support platform 12 is lifted and lowered to lift the mounting seat 2 and the support member 3 until two adjacent support members 3 are supported on the peripheral wall of the shaft cap 100. During the process of separating the shaft cap 100 and the core shaft 200, the shaft cap 100 can be effectively supported and fixed, and there is no need to frequently adjust the position of the shaft cap 100, which is beneficial to shortening the disassembly and assembly time to improve the disassembly and assembly efficiency. In addition, the shaft cap 100 is supported by the support member 3 and the trolley 1, and is not prone to falling and damage, which is beneficial to improving the safety of the shaft cap 100 during disassembly. Finally, after the fastener 300 between the shaft cap 100 and the mandrel 200 is disassembled, the trolley 1 can be moved to separate the shaft cap 100 and the mandrel 200. Since the axial direction of the support member 3 can extend along the direction of the central axis of the shaft cap 100 and move the trolley 1, the shaft cap 100 and the mandrel 200 are not prone to collision when the shaft cap 100 and the mandrel 200 are separated, which is also conducive to improving the safety of the shaft cap 100 during disassembly, and to a certain extent solves the problem of the disassembly efficiency being affected and the safety problem existing during the disassembly of the mandrel 200 and the shaft cap 100. In addition to being used in the disassembly process of the shaft cap 100 and the mandrel 200, the disassembly device can also be used in the installation process of the shaft cap 100 and the mandrel 200 to ensure the stable disassembly and coordination of the shaft cap 100 and the mandrel 200.

[0039] It should be noted that, due to the large mass of the shaft cap 100 itself, if part of the shaft cap 100 falls off during the process of being separated from the mandrel 200, on the one hand, the shaft cap 100 itself is easily damaged, and on the other hand, the shaft cap 100 may roll and affect other equipment or workers, causing safety problems. Therefore, reducing the possibility of the shaft cap 100 falling and colliding is also conducive to improving the safety of the shaft cap 100 during the disassembly and assembly process.

[0040] In some or certain embodiments, the columnar support member 3 may be prism-shaped or cylindrical-shaped, and may be configured according to usage conditions to improve the adaptability of the assembly and disassembly device.

[0041] In some or certain embodiments, at least two support members 3 may be arranged side by side and spaced apart from each other along their own radial direction A on the mounting seat 2. For the columnar shaft cap 100, the arrangement of at least two support members 3 arranged side by side and spaced apart from each other along their own radial direction A is relatively regular, and the radial direction A is nearly perpendicular to the axial direction of the support members 3. This arrangement also enables the two adjacent columnar support members 3 to stably support the radial sides of the shaft cap 100, improve the supporting and positioning effect of the shaft cap 100, and improve the stability of the shaft cap 100 during disassembly and assembly.

[0042] It should be noted that the radial direction A of the support member 3 can be a diameter extension direction of the support member 3 parallel to the surface 121 of the support platform 12, so as to achieve a better supporting effect.

[0043] In some or certain embodiments, the mounting seat 2 is a frame-shaped structure in which the frame-shaped hole 21 extends along the normal direction of the surface 121 of the supporting platform 12 , and the length of the supporting member 3 is less than or equal to the width of the mounting seat 2 .

[0044] The mounting seat 2 is a frame-type structure, and the overall preparation cost is low. The frame-shaped hole 21 extends along the normal direction of the surface 121 of the support platform 12, and the contact area between the mounting seat 2 and the support platform 12 is also large, and the installation space of the support member 3 is large. The length of the support member 3 is less than or equal to the width of the mounting seat 2, which can avoid interference and ensure the support effect, which is conducive to improving the efficiency of disassembly and assembly.

[0045] It should be noted that the frame-shaped hole 21 is a through hole provided by the frame structure itself, such as a rectangular hole in a rectangular frame, a triangular hole in a triangular frame, or a hole provided by a frame structure of other shapes.

[0046] In some or certain embodiments, there is a gap between the support member 3 and both ends or both sides of the mounting seat 2, and the radial direction A of the support member 3 extends along the axial direction of the mounting seat 2. The structure is relatively compact and the supporting effect is better.

[0047] In some or certain embodiments, the axial direction B of the support member 3 is arranged on the mounting seat 2 parallel to the surface 121 of the supporting platform 12, and the area of ​​the longitudinal section of the support member 3 decreases in the direction from the mounting seat 2 to the support member 3.

[0048] The axial direction B of the support member 3 is parallel to the surface 121 of the support platform 12 and is arranged on the mounting seat 2. On the one hand, the support platform 12 of the trolley 1 is usually arranged horizontally, and the axial direction of the support member 3 is parallel to the surface 121 of the support platform 12 to ensure the support effect on the shaft cap 100. On the other hand, in the direction where the mounting seat 2 points to the support member 3, the area of ​​the longitudinal section of the support member 3 is reduced, which can increase the contact area between the surface 121 of the support member 3 and the shaft cap 100, so as to improve the support effect of the shaft cap 100 and improve the safety during the disassembly and assembly process.

[0049] It should be noted that the surface 121 of the support platform 12 is a surface 121 of the support platform 12 that is used for support and is set as a plane. The axial direction B of the support member 3 is the axial direction of the support member 3, and the longitudinal section of the support member 3 is the surface obtained by cutting the support member 3 with a plane extending along the axial direction of the support member 3.

[0050] In some or certain embodiments, the support member 3 is a triangular prism, and one side of the support member 3 is closely connected to the mounting seat 2. The manufacturing cost is low, and the contact area with the peripheral wall of the shaft cap 100 is large, and the supporting effect is good.

[0051] In some or certain embodiments, the mounting seat 2 may also be configured as a block or plate, and the support member 3 may also be configured as, for example, a quadrangular prism or a hexagonal prism, etc., which can also provide effective support for the shaft cap 100 .

[0052] In some or certain embodiments, the disassembly and assembly device further includes a magnetic member 5, which is disposed on the mounting seat 2 and spaced from the support member 3 along the axial direction B of the support member 3. The magnetic member 5 can provide an adsorption force to the shaft cap 100 of a larger specification and made of ferromagnetic materials, etc., so as to increase the position stability of the shaft cap 100 during the disassembly and assembly process. The magnetic member 5 is disposed on the mounting seat 2 and spaced from the support member 3 along the axial direction B of the support member 3, so that the magnetic member 5 can apply an adsorption force to the shaft cap 100 without affecting the disassembly and assembly process of the shaft cap 100.

[0053] In some or certain embodiments, the magnetic member 5 may be an L-shaped plate, and the magnetic member 5 may be arranged on one side of the frame-shaped mounting seat 2, and the side close to the support member 3 protrudes from the mounting seat 2. The preparation is simple, and a certain adsorption force can be added to the shaft cap 100, and the positioning effect is also good.

[0054] In some or certain embodiments, the disassembly and assembly device further includes a fixing block 4, and both ends of the support member 3 are respectively connected to the mounting seat 2 through a fixing block 4. The fixing block 4 can increase the space between the support member 3 and the mounting seat 2 to facilitate adjustment of the position of the shaft cap 100 relative to the support member 3.

[0055] In some or certain embodiments, the support member 3 and the fixing block 4 are integrally formed to facilitate preparation.

[0056] In some or certain embodiments, the support member 3 and the fixing block 4 may also be connected and fixed by fasteners such as bolts.

[0057] In some or certain embodiments, the support platform 12 may include:

[0058] The platform body 122 can be raised and lowered relative to the base 11 .

[0059] The saddle 123 is connected to the platform body 122 , and the mounting seat 2 is sleeved and supported on the saddle 123 .

[0060] In the supporting platform 12, a saddle 123 is provided on the platform body 122, and the mounting seat 2 is sleeved and supported on the saddle 123. When there is no need to disassemble the shaft cap 100 and the core shaft 200, the mounting seat 2 can be separated from the saddle 123. The saddle 123 can be used to transport coils such as steel coils in the production line, thereby increasing the versatility of the disassembly and assembly device.

[0061] In some or certain embodiments, the mounting seat 2 may be a U-shaped frame structure, which is supported on the saddle 123 through its own rectangular hole. The mounting seat 2 may also be mounted on the saddle 123 through a groove that matches the shape of the saddle 123, which is convenient for disassembly and assembly.

[0062] In some or certain embodiments, the disassembly and assembly device may further include:

[0063] The support plate 6 is connected to the platform body 122 and is spaced apart from the saddle 123 .

[0064] The tightening column 7 passes through the support plate 6 and is threadedly engaged with the support plate 6 , and one end of the tightening column 7 is configured as a tightening end 71 opposite to the mounting seat 2 .

[0065] The support plate 6 provides support for the tightening column 7. The tightening end 71 of the tightening column 7 can apply pressure to the mounting seat 2 to tighten the mounting seat 2 and the saddle 123, thereby increasing the connection tightness between the mounting seat 2 and the saddle 123 and facilitating the disassembly of the mounting seat 2 and the saddle 123.

[0066] In some or certain embodiments, at least two spaced saddles 123 may be disposed on the platform body 122, at least one mounting seat 2 may be disposed on at least two saddles 123, and each mounting seat 2 may be provided with at least two supporting members 3. The disassembly and assembly of the shaft cap 100 is more flexible.

[0067] In some or certain embodiments, the tightening column 7 may be a stud or a bolt, etc., and the tightening end 71 may be one end of the stud or the threaded end of the bolt, which is convenient for preparation and implementation.

[0068] In some or certain embodiments, the lifting between the support platform 12 and the base 11 can be achieved by, for example, a telescopic cylinder or a motor-driven lifting mechanism. The trolley 1 can also be a lifting trolley, which is convenient for implementing this solution.

[0069] In some or certain embodiments, the axes of the plurality of rollers 13 extend in the same direction, and the rollers 13 may have their own locking mechanisms to limit the rolling of the rollers 13 relative to the base 11. The trolley 1 can be moved in the same direction, and the rollers 13 can be locked by the locking mechanism when the trolley 1 does not need to move, and the stability of the shaft cap 100 and the spindle 200 during disassembly and assembly is also good.

[0070] In some or certain embodiments, for the disassembly process of the core shaft 200 and the shaft cap 100 of some winders or uncoilers, if there is no such disassembly and assembly device, the disassembly and assembly process of the core shaft 200 and the shaft cap 100 will take at least 1 hour. With this tooling, the disassembly and assembly can be completed within 0.5 hours, and the broken wire needs to be replaced an average of 6 times a month. According to the average production speed of the rewinding production line, 1 roll of steel can be produced per hour, and each roll is 16 tons, with a profit of 300 yuan per ton. After the improvement, the annual profit can be increased by 300*16*1*0.5*6*12=172,800 yuan.

[0071] It should be noted that the parallel or perpendicular mentioned in the present application is relative to the concept of absolute parallel or absolute perpendicular in geometry, and a deviation of 0 to 5° is allowed, and the present application does not impose any limitation on this.

[0072] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0073] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
