Description

Technical Field

[0001] This application relates to the technical field of equipment maintenance, and in particular to a chain replacement device. Background Technology

[0002] The color-coated vertical looper is designed to store strip steel, ensuring continued production even during shutdowns caused by coil changing at the inlet and outlet or strip steel sewing. The vertical looper mainly consists of a winch, steel structure, looper trolley, sprocket assembly, and lifting chain. The sprocket assembly, in conjunction with the lifting chain, enables the looper trolley to rise and fall.

[0003] When the lifting chain needs to be replaced, a chain replacement device can be used. Existing chain replacement devices include an inlet frame, an outlet frame, and two main sprockets. The inlet mechanism works with one main sprocket to introduce the new chain. The outlet mechanism works with the other main sprocket to export the chain. Therefore, replacing the chain requires an inlet frame, an outlet frame, and at least two main sprockets, making the structure relatively complex. Thus, existing chain replacement devices suffer from structural complexity. Utility Model Content

[0004] The purpose of this application is to provide a chain changing device with a simple structure, including a frame, a drive unit, a sprocket, and a pressure wheel. The drive unit is disposed on the frame. The sprocket is connected to the drive unit, and the drive unit is used to drive the sprocket. The pressure wheel is disposed on the frame, and the pressure wheel and the sprocket are spaced apart to form a gap for the chain to pass through. The pressure wheel is used to press the chain passing through the gap against the sprocket.

[0005] Optionally, the frame includes a main body and a traveling device, the traveling device and the main body are movably connected, and the drive device, the sprocket and the pressure wheel are disposed on the traveling device.

[0006] Optionally, the chain replacement device further includes a telescopic rod, which is fixed to the main body and connected to the walking device. The telescopic rod is used to drive the walking device to move back and forth.

[0007] Optionally, the chain replacement device further includes a movable storage rack, which is disposed inside the frame and is used to store the chain.

[0008] Optionally, the movable storage rack is placed below the sprocket and below the pressure wheel.

[0009] Optionally, the movable storage rack and the rack are arranged separately.

[0010] Optionally, the rack includes a door frame for allowing the movable storage rack to enter and exit the rack.

[0011] Optionally, the width of the movable storage rack is smaller than the inner width of the door frame, and the height of the movable storage rack is smaller than the inner height of the door frame.

[0012] Optionally, the movable storage rack includes a base and four uprights, the base and the four uprights being connected to form a space for placing the chain.

[0013] Optionally, the central axis of the sprocket is parallel to the central axis of the pressure wheel.

[0014] The beneficial effects of this application are as follows: by setting up a frame, a drive unit, a sprocket, and a pressure wheel. The drive unit is set on the frame. The sprocket is connected to the drive unit, and the drive unit is used to drive the sprocket. The pressure wheel is set on the frame, and the pressure wheel and the sprocket are spaced apart to form a gap for the chain to pass through. The pressure wheel is used to press the chain passing through the gap against the sprocket.

[0015] By creating a gap between a single pressure wheel and a single sprocket for the chain to pass through, and by having the pressure wheel press the chain against the sprocket when the chain passes through the gap, the chain replacement device can be simplified without the need for an inlet frame, an outlet frame, and multiple drive sprockets.

[0039] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the accompanying drawings and embodiments. To enable those skilled in the art to better understand the solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0042] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] For ease of explanation, a rectangular coordinate system O-XYZ is established in some of the attached diagrams. The X-axis is parallel to frame 100 (refer to frame 100 for details). Figure 1 (The same below) In the width direction, make the Y-axis parallel to the length direction of the frame 100, and make the Z-axis parallel to the height direction of the frame 100. The positive directions of the X-axis, Y-axis and Z-axis are kept the same in each of the attached figures with coordinate systems.

[0044] like Figure 1 As shown, this embodiment provides a chain replacement device, including a frame 100, a drive unit 101, a sprocket 102, and a pressure wheel 103. The drive unit 101 is disposed on the frame 100. The sprocket 102 is connected to the drive unit 101, and the drive unit 101 drives the sprocket 102. The pressure wheel 103 is disposed on the frame 100, and the pressure wheel 103 and the sprocket 102 are spaced apart to form a gap for the chain 105 to pass through. The pressure wheel 103 is used to press the chain 105 passing through the gap against the sprocket 102.

[0045] like Figure 1 As shown, by forming a gap between a single pressure wheel 103 and a single sprocket 102 for the chain 105 to pass through, and when the chain 105 passes through the gap, the pressure wheel 103 can press the chain 105 against the sprocket 102. In this way, when replacing the chain 105, there is no need to set up an inlet frame, an outlet frame and multiple drive sprockets, which simplifies the structure of the chain replacement device.

[0046] Please also refer to Figure 1 and Figure 2The frame 100 can be a rectangular parallelepiped frame. The drive unit 101 may include a motor 1010 and a gearbox 1011. The motor 1010 and gearbox 1011 can be fixed to the top of the frame 100 by bolts. The output shaft of the motor 1010 and the input shaft of the gearbox 1011 can be connected by a coupling or a key. The sprocket 102 and the output shaft of the gearbox 1011 can be connected by a key. The central axis of the sprocket 102 can be parallel to the X-axis. The sprocket 102 is used to drive the chain 105. The sprocket 102 can be connected to the frame 100 through the drive unit 101. The sprocket 102 can be driven by the gearbox 1011 along... Figure 1 The bidirectional arrow in the image is used for directional driving.

[0047] like Figure 1 As shown, the sprocket 102 and the frame 100 are spaced apart (i.e., the sprocket 102 and the frame 100 do not contact each other). There is one sprocket 102. The clamping wheel 103 can be connected to the frame 100 via a support 104. There is one clamping wheel 103. The clamping wheel 103 and the support 104 are pivotally connected, and the support 104 can be fixed to the top of the frame 100 by welding or bolting.

[0048] like Figure 1 As shown, the central axis of the clamping wheel 103 can be parallel to the X-axis. The gap between the clamping wheel 103 and the sprocket 102 can be set such that when the chain 105 and the sprocket 102 are engaged, the side of the chain 105 away from the sprocket 102 just abuts against the side of the clamping wheel 103. The clamping wheel 103 is a driven wheel, and the chain 105 can drive the clamping wheel 103 to rotate when it is installed or removed.

[0049] Please also refer to Figure 1 and Figure 3 Optionally, the frame 100 includes a main body 1000 and a traveling device 1001. The traveling device 1001 and the main body 1000 are movably connected. The drive device 101, sprocket 102, and pressure wheel 103 are disposed on the traveling device 1001. The traveling device 1001 is configured to drive the drive device 101, sprocket 102, and pressure wheel 103 to move. This facilitates the coiling of the chain 105 when disassembling it and facilitates the delivery of the chain 105 when installing it.

[0050] Please also refer to Figure 2 and Figure 3 The main body 1000 can be a rectangular frame. The main body 1000 can consist of four channel steels at the top, four vertical channel steels in the middle, and two I-beams at the bottom. The length directions of the two I-beams can be parallel to each other and parallel to the Y-axis. The traveling device 1001 can be formed by welding the channel steels.

[0051] Please also refer to Figure 2 and Figure 3 The walking device 1001 may include four wheels 10010, two of which are embedded in a channel steel on the top of the body 1000, and the other two wheels 10010 are embedded in another channel steel on the top of the body 1000. The two channel steels for embedding the wheels 10010 are parallel to each other, and their length direction is parallel to the Y-axis. Drive device 101 (see [reference needed] for drive device 101) Figure 1 The sprocket 102 (hereinafter the same) and the support 104 can be fixed to the traveling device 1001 by welding or bolting. The sprocket 102 is fixed to the traveling device 1001 by the drive device 101. The traveling device 1001 can move back and forth in a direction parallel to the Y-axis.

[0052] like Figure 3 As shown, optionally, the chain replacement device also includes a telescopic rod 106, which is fixed to the main body 1000 and connected to the traveling device 1001. The telescopic rod 106 is used to drive the traveling device 1001 to reciprocate. By driving the traveling device 1001 to reciprocate via the telescopic rod 106, there is no need to install a separate motor to drive the traveling device 1001, which reduces the overall weight of the traveling device 1001 and consequently reduces the size of the traveling device 1001 and the frame 100 (see frame 100 for reference). Figure 1 Friction between them. The walking device 1001 can be a walking frame.

[0053] like Figure 3 As shown, the telescopic rod 106 can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. The axial direction of the telescopic rod 106 can be parallel to the Y-axis (i.e., the telescopic rod 106 can drive the traveling device 1001 to move back and forth in a direction parallel to the Y-axis). The telescopic rod 106 can be fixed to the top of the body 1000 by bolt connection. One end of the telescopic rod 106 can pass through the channel steel at the top of the body 1000. One end of the telescopic rod 106 can be connected to the side of the traveling device 1001 by welding or threaded connection.

[0054] like Figure 1 As shown, optionally, the chain replacement device also includes a movable storage rack 107, which is disposed inside the frame 100 and is used to store the chain 105. By providing the movable storage rack 107, it is easy to move the old chain 105 and bring in the new chain 105. The movable storage rack 107 can be a roughly rectangular frame structure.

[0055] like Figure 1As shown, optionally, the movable storage rack 107 is placed below the sprocket 102 and the pressure roller 103. This arrangement allows the chain 105 to be closer to the sprocket 102 and pressure roller 103 when installing or removing the chain 105, facilitating the chain 105 to fall onto the movable storage rack 107 or be hoisted from the movable storage rack 107 onto the sprocket 102. For example, the movable storage rack 107 can be placed directly below the sprocket 102 and pressure roller 103.

[0056] like Figure 1 As shown, optionally, the movable storage rack 107 and the rack 100 are spaced apart. This arrangement prevents the movable storage rack 107 from colliding with and damaging either the rack 107 or the rack 100 when the movable storage rack 107 enters or exits the rack 100. The spaced-apart arrangement means that the movable storage rack 107 and the rack 100 do not come into contact with each other.

[0057] Please also refer to Figure 1 and Figure 3 Optionally, the rack 100 includes a door frame 10000, which allows the movable storage rack 107 to enter and exit the rack 100. By providing the door frame 10000, the movable storage rack 107 can enter and exit the rack 100 without obstruction. There can be two door frames 10000, which can be located on the left and right sides respectively. The door frame 10000 can be constructed from a portion of two vertical channel steels and two I-beams. The door frame 10000 is generally inverted U-shaped. The bottom surface of the door frame 10000 can overlap with the ground to allow the movable storage rack 107 to pass through. The movable storage rack 107 can enter and exit the rack 100 through the door frame 10000 in a direction parallel to the Y-axis.

[0058] Please also refer to Figure 1 and Figure 3 Optionally, the width of the movable storage rack 107 is smaller than the inner width of the door frame 10000, and the height of the movable storage rack 107 is smaller than the inner height of the door frame 10000. This configuration allows the movable storage rack 107 to enter and exit the rack 100 from a direction perpendicular to the width of the door frame 10000 (i.e., from a direction parallel to the Y-axis). Compared to entering the rack 100 from other directions, a wider door frame 10000 is unnecessary, increasing the contact area between the rack 100 and the ground and reducing the risk of the rack 100 damaging the ground.

[0059] Please also refer to Figure 1 and Figure 3For example, if entry and exit are made from a direction parallel to the width of the door frame 10000 (i.e., from a direction parallel to the X-axis), the I-beam (which is longer) needs to be removed, reducing the contact area between the rack 100 and the ground, thus increasing the risk of the rack 100 damaging the ground. The inner width of the door frame 10000 is the distance between the two inner sides of the door frame 10000. The inner height of the door frame 10000 is the distance from the inner top surface of the door frame 10000 to the ground.

[0060] like Figure 4 As shown, optional, movable storage rack 107 (please refer to the movable storage rack 107). Figure 1 (The same applies below) includes a base 1070 and four uprights 1071. The base 1070 and the four uprights 1071 are connected, forming a space for placing the chain 105. By connecting the base 1070 and the four uprights 1071, the chain 105 is placed in the space formed by the base 1070 and the four uprights 1071, preventing the chain 105 from tipping over when stacked. The base 1070 can be plate-shaped. The base 1070 can be a steel plate. The movable storage rack 107 can be composed of the base 1070 and the four uprights 1071. The bottom of each upright 1071 can be triangular. The base 1070 and the four uprights 1071 can be connected by welding.

[0061] like Figure 4 As shown, the base 1070 and four uprights 1071 form a cuboid space to accommodate the folded chain 105. The base 1070 can be located at the bottom of each upright 1071. The uprights 1071 can be rectangular steel tubes. The length directions of each upright 1071 can be parallel to each other and parallel to the Z-axis. Two of the four uprights 1071 can be arranged facing each other to accommodate one end of the folded chain 105, and the other two of the four uprights 1071 can be arranged facing each other to accommodate the other end of the folded chain 105.

[0062] like Figure 5 Optionally, the central axis of the sprocket 102 is parallel to the central axis of the pressure wheel 103. This arrangement allows the chain 105 to be uniformly pressed in its width direction, preventing the chain 105 from coming off during assembly or disassembly.

[0063] Working principle of chain changing device:

[0064] Please also refer to Figure 1 and Figure 5When the chain 105 needs to be disassembled (the entire chain 105 weighs approximately 0.9 tons; the vertical looper is not shown in the diagram and is located outside the chain replacement device), the empty movable storage rack 107 is moved into the frame 100 in advance using a hydraulic trolley. Then, one end of the chain 105 to be disassembled is lowered into the gap between the sprocket 102 and the pressure wheel 103.

[0065] Please also refer to Figure 1 and Figure 5 The start-up drive unit 101 drives the sprocket 102 to reverse (reverse to) Figure 5 (In a counter-clockwise direction) guide the chain 105 to the movable storage rack 107. While lowering the chain 105, the telescopic rod 106 drives the traveling device 1001 to reciprocate in a direction parallel to the Y-axis. As the traveling device 1001 moves, it drives the sprocket 102, the pressure wheel 103, and the drive device 101 to reciprocate, thus coiling the chain 105 (coiling means stacking the chain 105). After all the chains 105 are placed in the movable storage rack 107, a hydraulic trolley is used to transport the movable storage rack 107 away. After all the chains 105 are placed in the movable storage rack 107, the central axis of each pin of the chain 105 is parallel to the X-axis.

[0066] Please also refer to Figure 1 and Figure 5 When it is necessary to install the chain 105 on the vertical looper, the movable storage rack 107 containing the coiled chain 105 is moved into the frame 100 in advance using a hydraulic trolley. One end of the chain 105 is hoisted upwards into the gap between the sprocket 102 and the pressure wheel 103 using a steel wire rope. The drive device 101 is then started to drive the sprocket 102 to rotate forward (forward rotation is...). Figure 5 The chain 105 is fed to the vertical looper in a clockwise direction. While the chain 105 is being fed, the telescopic rod 106 drives the traveling device 1001 to move back and forth in a direction parallel to the Y-axis. When the traveling device 1001 moves, it drives the sprocket 102, the pressure wheel 103 and the drive device 101 to move back and forth, so that the chain 105 can be reinstalled on the vertical looper.

[0067] The chain replacement device provided in the embodiments of this application has been described in detail above. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope.
