[0035] The elbow assembly / disassembly auxiliary device provided in this embodiment of the invention is simple to operate when removing the elbow from the work area. It avoids the problem of easy skewed pulling and lifting caused by the difficulty in determining the hoisting point during the operation of the prior art, which can lead to objects falling and causing safety accidents. At the same time, after the elbow is assembled / disassembled, it can be quickly transferred, reducing secondary operations and improving work efficiency.

[0036] The elbow disassembly and assembly auxiliary device and elbow disassembly and assembly auxiliary system provided in the embodiments of this utility model will be described by way of example below with reference to the accompanying drawings.

[0037] Figure 1 This is a schematic diagram of the structure of an auxiliary device for disassembling and assembling elbows provided in an embodiment of the present utility model. Figure 2 This is a structural schematic diagram of another elbow assembly / disassembly auxiliary device provided in an embodiment of this utility model. Figure 1 and Figure 2 The structures shown differ only in perspective. For example... Figure 1 and Figure 2As shown, the elbow assembly and disassembly auxiliary device includes: a bracket 10, a sliding base 12 and an adjustable sleeve structure 11. The bracket 10 is located above the sliding base 12, and the bracket 10 is fixed to the sliding base 12 by the adjustable sleeve structure 11.

[0038] The support 10 includes a first square structure 111 and a second square structure 112; the first square structure 111 and the second square structure 112 are both formed by four enclosing tubes in sequence.

[0039] The direction of the first square structure 111 is perpendicular to the direction of the second square structure 112, and the first square structure 111 and the second square structure 112 share a common enclosing tube 04; the direction of the first square structure 111 is parallel to the direction of the horizontal plane.

[0040] The adjustable sleeve structure 11 is located at the four corners of the first square structure 111, and the lower end of the adjustable sleeve structure 11 is fixedly connected to the sliding base 12.

[0041] The support 10 also includes a first diagonal bracing tube 08 and a second diagonal bracing tube 09; the first square structure 111 includes a first enclosing tube 01, and the second square structure 112 includes a second enclosing tube connection; the first enclosing tube 01 is arranged opposite to the common enclosing tube 04, and the second enclosing tube 02 is arranged opposite to the common enclosing tube 04; the first enclosing tube 01, the first diagonal bracing tube 08, the second enclosing tube 02, and the second diagonal bracing tube 09 are sequentially enclosed to form a third square diagonal bracing structure 113, which is used to support the elbow;

[0042] Among them, a first fixing ring 010 and a second fixing ring 011 are provided between the first diagonal bracing tube 08 and the second diagonal bracing tube 09; the middle position of the first fixing ring 010 and the first fixing ring 011 can be opened and closed to fix the elbow placed on the third triangular diagonal bracing structure 113.

[0043] Specifically, the elbow assembly / disassembly auxiliary device includes a bracket 10, a sliding base 12, and an adjustable sleeve structure 11, with the bracket 10 fixed to the sliding base 12 via the adjustable sleeve structure 11. The bracket 10 is made of DN50 steel pipe, and a first square structure 111, a second square structure 112, and a third square diagonal brace structure 113 are formed on the bracket 10. The third square diagonal brace structure 113 can hold the elbow. A first fixing ring 010 and a second fixing ring 011 are made of flat iron and installed on the third square diagonal brace structure 113 to fix the elbow and prevent it from slipping. The sliding base 12 has sliding locking components 114 (described below) installed at its four corners to ensure the device can move freely to the target position and remains fixed thereafter. Furthermore, the adjustable sleeve structure 11 between the bracket 10 and the sliding base 12 allows for height adjustment of the bracket 10.

[0044] The first square structure 111 is formed by the first enclosing pipe 01, the third enclosing pipe 03, the common enclosing pipe 04 and the sixth enclosing pipe 06 in sequence; the second square structure 112 is formed by the common enclosing pipe 04, the fifth enclosing pipe 05, the second enclosing pipe 02 and the seventh enclosing pipe 07 in sequence; and the third square diagonal bracing structure 113 is formed by the first enclosing pipe 01, the first diagonal bracing pipe 08, the second enclosing pipe 02 and the second diagonal bracing pipe 09 in sequence.

[0045] Specifically, in this embodiment of the invention, when using the elbow disassembly and assembly auxiliary device, the device is moved to the working area, for example, below the elbow, and the sliding base 12 is fixed, thereby securing the elbow disassembly and assembly auxiliary device. The height of the bracket 10 is adjusted so that the elbow is precisely placed on the triangular brace structure 113, and then the first fixing ring 010 and the second fixing ring 011 are used to fix the elbow. At this point, disassembly can begin. After disassembly is complete, the sliding locking component 114 of the sliding base 12 is unlocked, and the elbow is removed from the working area.

[0046] Therefore, the elbow disassembly and assembly auxiliary device provided in this embodiment of the utility model is simple to operate when removing the elbow from the work area, avoiding the problem of easy skewed pulling and lifting caused by the complex working environment and difficulty in determining the hoisting point in the existing technology, which can lead to objects falling and causing safety accidents. At the same time, after the elbow is disassembled and assembled, it can be quickly transferred, reducing secondary operations and improving work efficiency.

[0047] In some embodiments, such as Figure 1As shown, the slidable base 12 includes a first pair of base tubes 13 arranged opposite to each other and a second pair of base tubes 14 arranged opposite to each other; the length of the first pair of base tubes 13 is greater than the length of the second pair of base tubes 14, and the second pair of base tubes 14 is connected between the first pair of base tubes 13; the lower end of the adjustable sleeve structure 11 is fixedly connected to the base tubes of the slidable base 12, and each end of the first pair of base tubes 13 is provided with a sliding locking component 114.

[0048] The first pair of base tubes 13 includes a first base tube 012 and a second base tube 013, and the second pair of base tubes 14 includes a third base tube 014 and a fourth base tube 015. The first base tube 012 and the second base tube 013 are arranged in parallel and have the same length, and the third base tube 014 and the fourth base tube 015 are arranged in parallel and have the same length. The length of the first base tube 012 and the second base tube 013 is greater than the length of the third base tube 014 and the fourth base tube 015. Specifically, a sliding locking component 114 is provided at each end of the first base tube 012, and a sliding locking component 114 is provided at each end of the second base tube 013, thereby providing four sliding locking components 114.

[0049] Specifically, a sliding locking component 114 is provided, which enables the automatic movement of the elbow disassembly and assembly auxiliary device. Specifically, when the elbow disassembly and assembly auxiliary device moves to the target position, the position of the elbow disassembly and assembly auxiliary device can be fixed by locking the sliding locking component 114. Afterwards, if the elbow disassembly and assembly auxiliary device needs to be moved, the sliding locking component 114 can be unlocked.

[0050] In some embodiments, Figure 3 This is a partially exploded structural diagram of an auxiliary device for disassembling and assembling elbows provided in an embodiment of this utility model. (See attached diagram.) Figures 1 to 3 As shown, the sliding locking assembly 114 includes a sliding wheel 022, a rotating shaft 026, and a locking rod 020; each of the first pair of base tubes 13 has a rotating shaft 026 embedded at both ends, the rotating shaft 026 is connected to the sliding wheel 022, the rotating shaft 026 is provided with a slot 023, and the first pair of base tubes 13 is provided with an opening 024 corresponding to the slot 023 of the rotating shaft 026, and the locking rod 020 is inserted into the slot 023 through the opening 024.

[0051] Specifically, by setting up sliding wheels 022 and rotating shaft 026, when locking rod 020 is inserted into slot 023 of rotating shaft 026 through opening 024, the position of sliding base 12 can be fixed, thereby fixing the position of elbow disassembly and assembly auxiliary device; when locking rod 020 is not inserted into slot 023 of rotating shaft 026, sliding base 12 can move freely, thereby allowing elbow disassembly and assembly auxiliary device to move freely.

[0052] In some embodiments, such as Figures 1 to 3 As shown, the adjustable sleeve structure 11 is provided with a limiting structure 025, which is located near the opening 024 on the base tube; the limiting structure 025 is provided with a through hole 021, through which the insertion end of the locking rod 020 moves into and out of the opening 024.

[0053] Specifically, by setting a limiting structure 025, when the locking rod 020 is not inserted into the slot 023 of the rotating shaft 026, the limiting structure 025 can serve as a temporary storage structure for the locking rod 020; when the locking rod 020 needs to be inserted into the slot 023 of the rotating shaft 026, the limiting structure 025 can also serve as an auxiliary support structure for the locking rod 020, making it convenient for manual operation to insert the locking rod 020 into the slot 023 of the rotating shaft 026.

[0054] In some embodiments, such as Figures 1 to 3 As shown, the adjustable sleeve structure 11 includes an outer sleeve 016 and an inner sleeve 017; the top end of the outer sleeve 016 is fixedly mounted on the first square structure 111, and the bottom end of the inner sleeve 017 is fixedly mounted on the base tube, with the bottom end of the outer sleeve 016 facing the top end of the inner sleeve 017; the inner diameter of the outer sleeve 016 is larger than the outer diameter of the inner sleeve 017.

[0055] Specifically, by setting the adjustable sleeve structure 11 to include an outer sleeve 016 and an inner sleeve 017, the overall length of the adjustable sleeve structure 11 can be adjusted by moving the positional relationship between the outer sleeve 016 and the inner sleeve 017, thereby adjusting the height of the bracket 10.

[0056] In some embodiments, combined with Figures 1 to 3 Multiple pin holes 018 are provided at intervals on the side walls of both the outer sleeve 016 and the inner sleeve 017; the outer sleeve 016 and the inner sleeve 017 are fixed together by inserting a fixing pin 019 into the pin holes 018.

[0057] Therefore, after the overall length of the adjustable sleeve structure 11 is adjusted, the positions of the outer sleeve 016 and the inner sleeve 017 can be fixed by the fixing pin 019, that is, the overall length of the adjustable sleeve structure 11 can be fixed.

[0058] In some embodiments, both the first fixing ring 010 and the second fixing ring 011 are semi-circular arc-shaped. Specifically, the first fixing ring 010 and the second fixing ring 011 are both semi-circular arc-shaped to match the shape of the elbow. When the elbow is placed on the third-dimensional diagonal brace structure 113, the elbow placed on the third-dimensional diagonal brace structure 113 is fixed to prevent the elbow from falling off.

[0059] Therefore, the elbow disassembly and assembly auxiliary device provided in this embodiment of the utility model can avoid the use of a hand chain hoist, thereby eliminating the phenomenon of skewed pulling and tilting that occurs during elbow disassembly and assembly operations. It also achieves the goal of rapid transfer after disassembly. This utility model has a simple structure and is easy to manufacture, enabling its rapid adoption in elbow disassembly and assembly operations. It also eliminates the previous situation where personnel were manually holding the hoisted object, which could lead to the elbow falling and causing injury.

[0060] Based on the above embodiments, this utility model provides an elbow disassembly and assembly auxiliary system, including the elbow disassembly and assembly auxiliary device as described in the above embodiments, and therefore has the same or similar beneficial effects, which will not be repeated here.
