Description

Technical Field

[0001] This patent relates to the field of crane technology, specifically a tubular workpiece crane lifting tool. Background Art

[0002] Crane refers to a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called overhead crane, overhead crane, and crane. Tubular workpieces are pipes and tubes. On the construction site, tubular workpieces need crane lifting tools to suspend them on high-altitude buildings for use. However, the current tubular workpiece crane lifting tools generally use ropes to tie the tubular workpieces when lifting tubular workpieces, and then hang them on the crane hook for suspension. Since the ropes are loose, the suspension causes dangerous problems.

Round holes 403 are respectively opened on the rubber blocks 402. The two sides of the tubular workpiece 404 are respectively inserted into the round holes 403. The tubular workpiece 404 is manually inserted into the round holes 403 on the rubber blocks 402 on both sides of the box body 1 one by one, and the rubber blocks 402 increase the friction between the tubular workpiece 404 and the through holes 401 on the box body 1. Then the crane suspends the rope, so that the hook 3 drives the tubular workpiece 404 in the box body 1 to be suspended to the specified position through the vertical plate 2. During the suspension process, the damage caused by the loosening and falling of the tubular workpiece 404 is avoided.

[0029] A square plate 8 is installed in the box body 1, and five transverse and five longitudinal pipe openings 9 are opened on the square plate 8. The pipe openings 9 correspond to the tubular workpieces 404 one by one, and the tubular workpieces 404 pass through the pipe openings 9;

[0030] An elastic structure 10 is installed in the pipe mouth 9. The number of the elastic structures 10 is six. The elastic structures 10 are distributed in the pipe mouth 9 in an annular shape and at equal intervals. The elastic structure 10 includes a groove 11, a spring 12 and a ball 13.

[0031] The groove 11 is opened in the pipe mouth 9, the spring 12 is installed in the groove 11, and the ball 13 is installed on the spring 12. The ball 13 is pressed against the outside of the tubular workpiece 404. When the tubular workpiece 404 is inserted into the box body 1, it is simultaneously inserted into the pipe mouth 9 on the square plate 8. The spring 12 in the groove 11 gives the ball 13 an inward force, and the ball 13 is pressed against the tubular workpiece 404, so that it is fixed and limited in the box body 1, to prevent the tubular workpiece 404 from loosening and falling off during the suspension process.

[0032] The box body 1 is provided with a blocking structure 14, and the number of the blocking structures 14 is two. The blocking structures 14 are symmetrically distributed on both sides with the center line of the box body 1 as the center.

[0033] The blocking structure 14 includes a sleeve plate 15, a horizontal plate 16, a baffle plate 17, a threaded hole 18, a bolt 19 and a handle 20;

The elastic member can be an elastic workpiece such as a spring. When the insert block 7 is retracted into the slot 6, the elastic member is compressed. At this time, the opening on the hook 3 can be opened to allow the crane rope to enter. Conversely, the elasticity of the elastic member causes the insert block 7 to pop out and seal the opening of the hook 3 to prevent the crane rope from escaping from the hook 3.

[0037] When using the tubular workpiece crane lifting tool, firstly, the insert block 7 is manually retracted into the slot 6, and the elastic member is compressed. At this time, the opening on the hook 3 can be opened to allow the crane rope to enter. Conversely, the elasticity of the elastic member causes the insert block 7 to pop out and seal the opening of the hook 3 to prevent the crane rope from escaping from the hook 3. The inclined plate 5 strengthens the connection between the vertical plate 2 and the box body 1. The tubular workpiece 404 is manually inserted into the circular holes 403 on the rubber blocks 402 on both sides of the box body 1 one by one. The rubber blocks 402 increase the friction between the tubular workpiece 404 and the through holes 401 on the box body 1. When the tubular workpiece 404 is inserted into the box body 1, the corresponding insertion square is simultaneously The spring 12 in the groove 11 applies inward force to the ball 13, and the ball 13 presses against the tubular workpiece 404 to fix it in the box body 1. Then, when the tubular workpiece 404 is placed in the box body 1, the baffle 17 moves close to the two ends of the tubular workpiece 404 and contacts the tubular workpiece 404. At the same time, the cross plate 16 is retracted into the sleeve plate 15. After the position of the baffle 17 is adjusted, the handle 20 is screwed to screw the bolt 19 into the threaded hole 18 and press it against the cross plate 16 for fixation. Then the crane suspends the rope to make the hook 3 drive the tubular workpiece 404 in the box body 1 to be suspended to the specified position through the vertical plate 2.
