Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a crane for lifting tubular components. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range; it is also called an overhead crane, gantry crane, or hoist. Tubular workpieces refer to pipes or tubes. On construction sites, tubular workpieces require crane lifting tools to suspend them at high altitudes. However, current crane lifting tools for tubular workpieces typically use ropes to bind the workpiece and then hang it from the crane hook. Because the rope binding can become loose, this can create a dangerous situation. Furthermore, if the binding is not at the center of the tubular workpiece, resulting in different lengths at both ends, the workpiece can easily tilt, increasing the risk of accidental detachment and thus posing corresponding safety hazards during the lifting process.

[0020] Reference Figures 1 to 6 As shown, this utility model provides a crane for hoisting tubular components, including: an auxiliary component 4. The crane body 1 is fixedly connected to the auxiliary component 4 through a hoisting component 2. The auxiliary component 4 consists of a storage frame 12, a fastening plate 10, and a fixing plate 3. The upper surface of the fixing plate 3 is fixedly connected to the hoisting component 2. The two sides of the fixing plate 3 are fixedly connected to clamping plates 5 through fixing ropes 7. The surface of the clamping plate 5 is symmetrically connected to fitting blocks 6. The two sides of the storage frame 12 are symmetrically connected to guide components 11. The fixing ropes 7 are slidably connected to the outer side of the storage frame 12 through the guide components 11. The upper surface of the storage frame 12 is symmetrically screwed with fastening screws 8 through screw holes. The lower end of the fastening screws 8 is movably connected to the fastening plate 10 through a bearing. At the same time, the bottom of the inner cavity of the storage frame 12 is fixedly connected to the main fastening layer 14.

[0021] In this embodiment, the tubular components are sequentially embedded into the storage frame 12. The fastening screw 8 is rotated, and it pushes the fastening plate 10 downwards through the screw hole, causing the secondary fastening layer on the lower surface of the fastening plate 10 to adhere to the surface of the tubular component. The hoisting assembly 2 of the crane body 1 is pre-started, allowing the hoisting assembly 2 to move the fixed plate 3 upwards a certain distance. The fixed plate 3, through the fixing rope 7, can synchronously move the clamping plate 5. At this time, the worker adjusts the position of the clamping plate 5 so that the fitting blocks 6 on the surface of the clamping plate 5 can be embedded into the openings at both ends of the tubular component. The hoisting assembly 2... Through the cooperation of the fixing plate 3, the fixing rope 7 and the clamping plate 5, the loading frame and the tubular component can be lifted off the ground and suspended in the air. At this time, the tubular component will move relative to the loading frame under the clamping of the two sets of clamping plates 5, so that the loading frame can be located in the center of the tubular component. Then, the fastening screw 8 is rotated again, and the fastening screw 8 pushes the fastening plate 10 to abut against the fixed tubular component, realizing double-layer fixation of the tubular component. Then, the lifting assembly 2 of the crane body 1 is started, so that multiple sets of tubular components can be stably lifted and moved in batches, enhancing the safety of the tubular component lifting and moving.

[0022] As a preferred embodiment, the storage frame 12 has a square cylindrical structure, four sets of guide components 11 are symmetrically connected on both sides of the outer side of the storage frame 12, and the main fastening layer 14 fixedly connected to the bottom of the inner cavity of the storage frame 12 has a rectangular structure.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3, the structural setting of the storage frame 12 enables multiple groups of tubular parts to be placed in batches inside the auxiliary component 4, thereby improving the hoisting and moving efficiency of the tubular parts.

[0024] As a preferred embodiment, the guiding component 11 is composed of three guiding blocks. The three guiding blocks are distributed in an L shape on the outer side of the storage frame 12, and the guiding blocks are in an overall cuboid structure.

[0028] As a preferred embodiment, the fastening plate 10 is in a rectangular structure. The length dimension of the fastening plate 10 is adapted to the width dimension of the inner cavity of the storage frame 12. The positions of both ends of the fastening plate 10 corresponding to the guiding grooves 9 are connected to the guiding blocks 13 respectively. The guiding blocks 13 are in a rectangular structure. At the same time, the fastening plate 10 and the guiding blocks 13 are combined together to form a structure like the Chinese character "Shen".
