Description

Technical Field

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

[0002] Currently, long profiles (such as bundles of steel pipes) are typically hoisted using specialized gantry cranes due to their considerable length, ensuring stable lifting. The hoisting mechanism of a gantry crane generally includes an electric gear mechanism and connecting plate, movable hooks, a frame, and a cross frame. The upper middle part of the cross frame is fixedly installed at the lower end of the connecting plate. The electric gear mechanism and connecting plate are mounted on the frame, and the uppermost part of the frame is installed under the trolley. The lower front and rear sides of the cross frame have multiple openings spaced at intervals. Two movable hooks are installed through fixed holes at their upper ends and via movable pins into two of these openings on either side of the cross frame.

[0003] When the existing long profile-specific gantry-type hoisting equipment moves the two movable hooks to different distances under the horizontal frame, it requires manual operation and adjustment by the staff, which causes inconvenience to the staff and is not conducive to improving work efficiency.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the lifting equipment used for aluminum profile processing. Figure 2 This is a schematic diagram of the slide 104. This utility model provides a lifting device for aluminum profile processing: it includes a body 101, a pulley mechanism, and an adjusting mechanism. The adjusting mechanism includes a bearing seat 102, an adjusting screw 103, a slide 104, a reducer 105, a first gear 106, a second gear 107, a guide rod 108, a signal device, and a hook device. The signal device includes a bracket 109 and a detection switch 110. The hook device includes a hook 111 and a mounting assembly 112. The pulley mechanism includes an auxiliary frame 113 and a cooperating pulley 114. This design enables automatic adjustment of the hook spacing during use; that is, the aforementioned design can automatically adjust the working distance of the working hook.

[0021] In this embodiment, a pulley mechanism is provided on the top of the machine body 101, and the pulley mechanism cooperates with the telescopic steel wire rope of the external lifting mechanism.

[0022] The bearing housing 102 is fixedly connected to the machine body 101 and is arranged in pairs on both sides of the machine body 101. The adjusting screw 103 is rotatably connected to the bearing housing 102 and is symmetrically arranged. The slide 104 is slidably connected to the machine body 101 and threadedly connected to the adjusting screw 103. The reducer 105 is fixed to the machine body 101, and its output shaft is connected to the adjusting screw 103 through a coupling. The first gear 106 is fixed to the adjusting screw 103, and the second gear 10... 7 is fixed on the output shaft of the reducer 105 and meshes with the first gear 106. The guide rod 108 is integrally formed with the slide 104 and slides in cooperation with the guide groove on the body 101, and is symmetrically arranged. The signal device is set on the body 101, and the hook device is set at the bottom of the slide 104. The bearing seats 102 are fixed by positioning pins and bolts and are matched in pairs. The two sides of the adjusting screw 103 are mounted on the bearing seats 102 by rotating bearings. The reducer 105 is bolted to the rectangular mounting plate of the body 101. Its output end is connected to the adjusting screw 103 via a coupling. The reducer 105 adopts a locking structure, such as the device disclosed in prior art CN221569362U, for locking the shaft when stopping. Other existing devices with locking structures can also be used; no single limitation is made here. The first gear 106 is fixed to the adjusting screw 103 via a flat key and locking bolts, and the second gear 107 is fixed to the adjusting screw 103 via a flat key. The slide block 104 is bolted to the output shaft of the reducer 105 and meshes with the first gear 106. The slide block 104 has a rectangular portion that slides and limits the movement of the body 101. This structure facilitates the bearing of force during direct hoisting and also prevents deformation of the adjusting screw 103. The guide rod 108 is integrally set at the bottom of the slide block 104 and slides with the guide groove on the body 101. The signal device is used to detect the position of the slide block 104, and the hook device is used to hoist the profile.

[0023] The sliding contact surfaces of the body 101 with the slide block 104 and the guide rod 108 are respectively coated with wear-resistant coatings. This structure helps to extend the service life of the body 101, and the slide block 104 that wears out faster can be directly replaced in the future.

[0024] Secondly, the bracket 109 is detachably connected to the body 101 and is symmetrically arranged; the detection switch 110 is disposed on the bracket 109. The bracket 109 is fixed by bolts arranged from bottom to top and has mounting holes. The detection switch 110, model LJ12A3-4-Z / BX, is fixed to the bracket 109 by a self-locking threaded plate and is used to detect the position of the slide 104 for limiting movement.

[0025] Then, the hook 111 is detachably installed below the slide block 104; the mounting assembly 112 is detachably connected to the slide block 104 and the hook 111 respectively. The mounting assembly 112 includes a T-shaped connecting rod and a locking nut, and the hook 111 can be set at the bottom of the slide block 104 through the mounting assembly 112.

[0026] Finally, the auxiliary frame 113 is integrally formed with the body 101 and is located on the top of the body 101; the mating pulley 114 is disposed on the auxiliary frame 113. The auxiliary frame 113 is provided with a detachable mounting arm by high-strength bolts arranged from bottom to top, and the mounting arm is provided with mating holes for the rotating stepped shafts on both sides of the mating pulley 114 to provide rotational support.

[0027] When using this utility model to automatically adjust the hook spacing, the machine body 101 cooperates with the telescopic steel wire rope of the external lifting mechanism through the pulley mechanism. Then, the hooks can cooperate with the lifting straps set on the profile, and the profile is lifted and lowered when the telescopic steel wire rope of the external lifting mechanism is raised and lowered. When it is necessary to adjust the spacing of the hook devices, the operator can directly control the reducer 105 through the mobile operating box. The action of the reducer 105 can drive the adjusting screw 103 to rotate. After the adjusting screw 103 rotates, the slide 104 can be moved, thus realizing the automatic adjustment of the spacing between the hook devices. Then, the worker can hook relatively long profile goods on the two hooks 111 for lifting. The detection device is used for limit detection. After a signal is detected on one side, the reducer 105 needs to be controlled to reverse the action to drive it. This also avoids manual adjustment when needed, thus enabling automatic adjustment of the hook spacing during use.

[0028] Example 2:

[0029] like Figure 3 As shown, where Figure 3This is a schematic diagram of the overall structure of the lifting equipment for aluminum profile processing. Based on the first embodiment, this utility model provides a lifting equipment for aluminum profile processing. The adjustment mechanism also includes a reinforcing frame 201. The reinforcing frame 201 is fixedly connected to the body 101 and the auxiliary frame 113 respectively, and is arranged symmetrically.

[0030] In this embodiment, the reinforcing frame 201 is arranged in a figure-eight shape, and its two ends are fixed by high-strength bolts. After being set up, it is used to improve the stability of the auxiliary frame 113.
