Description

Technical Field

[0001] This utility model relates to the field of gate maintenance technology, and in particular to a hinge disassembly tool. Background Technology

[0002] As a common type of gate in water conservancy facilities, the arc gate mainly consists of four parts: gate leaf, support arm, hinge, and hydraulic cylinder. When the gate is in operation, it moves in an arc around the hinge, relying on the support arm and hinge.

[0003] The hinge device consists of components such as a hinge seat, hinge chain, bearing, hinge shaft, and stop plate. The hinge chain connects to the support arm and is the movable end; the hinge seat connects to the embedded parts in the concrete foundation and is the fixed end; the hinge chain and hinge seat are rotatably connected by the bearing.

[0004] When performing maintenance on the hinge, the entire hinge must be disassembled and transported to a specialized processing plant for disassembly, inspection, and maintenance. However, due to space constraints, the support arm must be removed before disassembling the hinge. Currently, the following problems exist when disassembling the support arm and hinge: the hinge seat and hinge chain of the hinge are relatively movable. After the support arm is removed, the hinge seat, as the fixed end, remains stationary, while the hinge chain, as the movable end, will rotate downwards around the bearing of the hinge seat due to the loss of force. This will lead to two consequences: first, the hinge chain may suddenly rotate downwards around the bearing of the hinge seat, potentially with too large an amplitude, causing the entire hinge device to swing violently, posing a safety risk to construction personnel and equipment; second, since the installation angles of the support arm, hinge, and embedded parts in the concrete foundation need to remain fixed, changes in the angles of the hinge seat and hinge chain will require readjustment of the hinge seat and hinge chain angles when reinstalling the hinge device. This usually requires repeated adjustments using a hand-operated hoist, which is time-consuming and labor-intensive. Utility Model Content

[0005] In order to solve the problem in the background technology that when the support arm is removed, the hinge will suddenly rotate downward around the bearing of the hinge seat, which not only poses a safety risk, but also causes the hinge and hinge seat to need to be repeatedly adjusted in angle during reinstallation, this utility model proposes a support hinge disassembly tool.

[0006] The technical solution of this utility model is: a hinge disassembly tool, including a hinge seat and a hinge chain connected by hinges, a hinge seat end plate away from the hinge chain is fixedly connected to a concrete base, a hinge chain end plate away from the hinge seat is used to be fixedly connected to a support arm, and also includes a plurality of cross braces arranged around the hinge seat and the hinge chain and cross bracing between the hinge seat end plate and the hinge chain end plate, one end of the cross brace is provided with a length adjustment member, the length of the length adjustment member is adjustable, one end of the length adjustment member abuts against the hinge chain end plate, and the length adjustment member is used to press and fix the end of the cross brace away from the length adjustment member onto the hinge seat end plate.

[0007] All the cross braces are surrounded by a U-shaped vertical brace, which is used to clamp the cross braces between the hinge seat and the hinge.

[0008] Preferably, the cross brace is an I-beam or U-shaped steel structure, and a fixing plate is fixed at one end of the cross brace. The fixing plate has a first screw hole that is open to the left and right.

[0009] The length adjustment component includes a fixed nut fixed on a fixed plate and an adjusting screw threaded to the fixed nut. The fixed nut is coaxially arranged with the first screw hole, and the adjusting screw passes through the fixed nut and the first screw hole. One end of the adjusting screw abuts against the hinge end plate.

[0010] Preferably, the vertical support member is fixedly provided with an inner support strip on the side facing the horizontal support, and the inner support strip is inserted into the groove of the horizontal support itself.

[0011] Preferably, at least two vertical bracing members are provided around the outer sides of all the cross braces, and at least one vertical bracing member is provided on both the hinge seat and the hinge.

[0012] Preferably, a horizontal plate is fixedly provided at the top of the vertical support member near the hinge seat, which is vertically arranged and extends in the front-back direction, and the top of the horizontal plate is higher than the top of the hinge seat end plate.

[0013] Preferably, the side of the horizontal plate away from the hinge end plate is hinged to a diagonal brace that can swing up and down. The diagonal brace is a rod-shaped structure with adjustable length, and the end of the diagonal brace away from the horizontal plate is used to abut against the adjacent vertical support member.

[0014] Preferably, the vertical support component includes vertical rods disposed on the front and rear sides of the hinge seat and the hinge. The vertical rods include a first vertical rod segment and a second vertical rod segment. An adjustable length connector is connected between the lower end of the first vertical rod segment and the upper end of the second vertical rod segment. A horizontal rod can be detachably connected between the upper ends of the two first vertical rod segments and the lower ends of the two second vertical rod segments.

[0015] Preferably, the connector includes a first connecting plate, a second connecting plate, and bolts;

[0016] The first connecting plate is fixed at the lower end of the first vertical rod section, and the second connecting plate is located at the lower end of the second vertical rod section. Both the first and second connecting plates are provided with corresponding second screw holes, and bolts are inserted into the second screw holes to connect the first and second connecting plates.

[0017] Preferably, multiple first ribs with vertical spacing are fixed on both the front and rear sides of the hinge base, multiple second ribs with vertical spacing are fixed on both the upper and lower sides of the hinge base, multiple third ribs with vertical spacing are fixed on both the front and rear sides of the hinge, and multiple fourth ribs with vertical spacing are fixed on both the upper and lower sides of the hinge.

[0018] The bottom of the upper horizontal brace abuts against the top of the uppermost first and third ribs, while the top of the lower horizontal brace abuts against the bottom of the lowermost first and third ribs.

[0019] Advantages of this utility model: In use, this fixture employs multiple cross braces surrounding the hinge seat and hinge, positioned between the hinge seat end plate and the hinge end plate. A length adjustment component is used to press and fix the end of the cross brace furthest from the length adjustment component onto the hinge seat end plate, initially limiting the rotation angle of the hinge seat and hinge. Then, a U-shaped vertical brace component surrounds the outer sides of all the cross braces, hinge seat, and hinge, clamping the cross braces between the hinge seat and hinge, further improving the cross braces' resistance to slippage and deformation. This ensures that when disassembling the support arm and hinge, the hinge will not rotate downwards around the hinge seat bearing after the support arm is removed, guaranteeing that the angle of the hinge and hinge seat remains unchanged after disassembly. Therefore, no further adjustment of the hinge and hinge seat angle is required during subsequent reassembly, improving maintenance efficiency and safety. Attached Figure Description
