Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to an aluminum alloy profile lifting device. Background Technology

[0002] Lifting machinery refers to electromechanical equipment used for vertically lifting or vertically lifting and horizontally moving heavy objects. Lifting machinery can be classified into several categories according to its structure, including light and small lifting equipment, elevators, cranes, and overhead monorail systems. Light and small lifting equipment is mostly small in size, lightweight, and easy to use. Manually controlled light and small lifting equipment is often used in aluminum profile processing. However, most manually controlled light and small lifting equipment can only achieve simple lifting and hoisting of profiles; it cannot move the lifted profiles horizontally, or moving them is difficult, which causes inconvenience to the work.

[0003] Existing patent number CN217732486U discloses a hoisting device for aluminum profile processing, including a main beam, a support frame, and a support base. The upper surface of the support frame has two symmetrical sliding grooves, each containing a slider. The upper surface of the slider is connected to the main beam. A hoisting trolley is slidably connected above the main beam via a third sliding groove, and a hand-operated hoist is installed below the hoisting trolley. This hoisting device for aluminum profile processing allows the main beam and hoisting trolley to move horizontally (left, right, forward, and backward) by rotating handles one and two, thus simplifying operation and improving work efficiency.

[0004] Using the above method, it was found that the pulley lacks a limiting mechanism, which can easily lead to accidental contact with the pulley, causing it to rotate and thus changing the position of the workpiece. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum alloy profile lifting device, which solves the problem found in the use of existing devices that the pulley has no limiting mechanism, which can easily cause accidental contact with the pulley, resulting in the pulley rotating and thus changing the position of the workpiece.

[0006] To achieve the above objectives, this utility model provides an aluminum alloy profile lifting device, including a support base, a pulley, and a lifting mechanism. The pulley is mounted on the support base via a support rod, and the lifting mechanism is disposed on the support base.

[0007] The device also includes a limiting mechanism, which comprises a fixed base, a positioning column, a clamping block, a limiting plate, a moving component, and a locking component. The fixed base is fixedly installed on the support base, the positioning column is rotatably installed on the fixed base, the clamping block is fixedly installed on the positioning column, the limiting plate is disposed on the clamping block via the moving component, and the locking component is disposed on the clamping block.

[0008] The movable component includes a movable block and a screw. The movable block is fixedly connected to the limiting plate, and the screw is mounted on the clamping block via a bearing. The movable block is threadedly connected to the screw.

[0009] The moving component further includes a rotary switch and a protective pad. The rotary switch is fixedly mounted on the screw, and the protective pad is detachably mounted on the limiting plate.

[0010] The locking assembly includes a locking threaded hole and a locking bolt. The locking threaded hole is located on the clamping block, and the locking bolt matches the locking threaded hole.

[0011] The locking assembly further includes a magnet one and a magnet two. The magnet one is fixedly installed on the clamping block, and the magnet two is fixedly installed on the support base.

[0012] This utility model discloses an aluminum alloy profile lifting device. When it is necessary to limit the pulley, rotating the clamping block causes the first magnet and the second magnet to disengage. After the clamping block contacts the pulley, the rotary switch drives the screw to rotate. The rotation of the screw drives the moving block to move, and the movement of the moving block drives the limiting plate to move and contact the pulley. At this time, the limiting plate and the clamping block cooperate to resist and fix the pulley, preventing the pulley from rotating accidentally. This solves the problem found in the use of existing devices where the pulley lacks a limiting mechanism, which easily causes accidental contact with the pulley, resulting in pulley rotation and thus changing the position of the workpiece.

[0021] This embodiment provides an aluminum alloy profile lifting device, including a support base 101, a pulley 102, a lifting mechanism 103, and a limiting mechanism. The limiting mechanism includes a fixed base 104, a positioning column 105, a clamping block 106, a limiting plate 107, a moving component, and a locking component. The moving component includes a moving block 108 and a screw 109, and also includes a rotary switch 110 and a protective pad 111. The locking component includes a locking threaded hole 112 and a locking bolt 113, and also includes a magnet 114 and a magnet 115. The aforementioned solution solves the problem found in the use of existing devices where the pulley 102 lacks a limiting mechanism, which easily leads to accidental contact with the pulley 102, causing the pulley 102 to rotate and thus changing the position of the workpiece.

[0022] In this embodiment, the pulley 102 is mounted on the support base 101 via a support rod, and the lifting mechanism 103 is disposed on the support base 101. The lifting mechanism 103 includes a main beam, a support frame, a first slide groove, a slider, a first support plate, a first threaded rotating rod, a first pulley, a first transmission belt, a support rod, a second pulley, a third pulley, a connecting column, a fixing plate, a second transmission belt, a third slide groove, a mounting plate, a second slide groove, a hoist, a second support plate, a second threaded rotating rod, a fifth pulley, a fourth pulley, a second rotating handle, a third transmission belt, and a first rotating handle, etc. This structure adopts the connection method and principle in the prior art comparison document, therefore, it will not be described in detail here. The pulley 102 is limited by the cooperation of the limiting plate 107 and the clamping block 106 to prevent accidental rotation.

[0023] The fixed base 104 is fixedly mounted on the support base 101, the positioning post 105 is rotatably mounted on the fixed base 104, the clamping block 106 is fixedly mounted on the positioning post 105, the limiting plate 107 is disposed on the clamping block 106 via the moving component, the locking component is disposed on the clamping block 106, the clamping block 106 has a limiting groove, the limiting plate 107 is located in the limiting groove, the limiting plate 107 and the clamping block 106 are in contact with the pulley 102, and the clamping block 106 and the limiting plate 107 are made of corrosion-resistant material. The fixed base 104 and the positioning post 105 are made of metal. When it is necessary to limit the pulley 102, after the clamping block 106 is rotated to contact the pulley 102, the moving component drives the limiting plate 107 to move and contact the pulley 102. At this time, the limiting plate 107 and the clamping block 106 cooperate to resist and fix the pulley 102, preventing the pulley 102 from rotating accidentally. This solves the problem found in the use of the existing device that the pulley 102 does not have a limiting mechanism, which easily causes accidental contact with the pulley 102, thereby causing the pulley 102 to rotate and thus changing the position of the workpiece.

[0024] Secondly, the movable block 108 is fixedly connected to the limiting plate 107, the screw 109 is mounted on the clamping block 106 through a bearing, the movable block 108 is threadedly connected to the screw 109, the clamping block 106 has a movable groove that communicates with the limiting groove, the movable block 108 is located in the movable groove, the movable block 108 has a threaded hole that matches the screw 109, and the clamping block 106 has a slot that matches the screw 109. The movable block 108 is moved by the rotation of the screw 109, and the movement of the movable block 108 causes the limiting plate 107 to move.

[0025] Furthermore, the rotary switch 110 is fixedly mounted on the screw 109, and the protective pad 111 is detachably mounted on the limiting plate 107. The protective pad 111 is installed on the side of the clamping block 106 that contacts the pulley 102. The protective pad 111 protects the pulley 102, and the rotary switch 110 drives the screw 109 to rotate.

[0026] Meanwhile, the locking threaded hole 112 is located on the clamping block 106, and the locking bolt 113 matches the locking threaded hole 112. The locking threaded hole 112 is connected to the slot. After the position of the moving block 108 is adjusted, the locking bolt 113 is rotated to contact the screw 109, thereby resisting and fixing the screw 109 and preventing the screw 109 from rotating.

[0027] In addition, the first magnet 114 is fixedly installed on the clamping block 106, and the second magnet 115 is fixedly installed on the support base 101. The first magnet 114 and the second magnet 115 correspond to each other and are magnetically connected. When the limiting plate 107 is not needed, the clamping block 106 is rotated so that the first magnet 114 and the second magnet 115 are attracted together.

[0028] When using the aluminum alloy profile lifting equipment of this embodiment, when it is necessary to limit the pulley 102, the clamping block 106 is rotated to disengage the first magnet 114 and the second magnet 115. After the clamping block 106 contacts the pulley 102, the rotary switch 110 drives the screw 109 to rotate. The rotation of the screw 109 drives the moving block 108 to move. The movement of the moving block 108 drives the limiting plate 107 to move and contact the pulley 102. At this time, the limiting plate 107 and the clamping block 106 cooperate to resist and fix the pulley 102, preventing the pulley 102 from rotating accidentally. This solves the problem found in the use of existing devices that the pulley 102 does not have a limiting mechanism, which easily causes accidental contact with the pulley 102, thereby causing the pulley 102 to rotate and thus changing the position of the workpiece.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
