Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, specifically to a hoisting device for coiled steel. Background Technology

[0002] Coiled steel bars are a type of steel used in construction. They are spiral steel bars coiled like springs with ribs on their surface. These ribs increase the bond between the steel bars and concrete, allowing them to work together better to bear various loads in the building structure. When moving coiled steel bars, lifting equipment is needed to lift them for transfer.

[0003] Existing technologies, such as patent document CN220148998U, disclose a coil material lifting device, including a lifting tool, a boom, a handle, and reinforcing ribs. The lifting tool is hook-shaped and extends into the coil material to be lifted. The lifting tool includes a crossbeam and main ribs, and the crossbeam has several anti-slip grooves. The boom is located at the top of the lifting tool and is inclined. The boom and the lifting tool are fixedly connected, and the boom has lifting holes. The handle is located on one side of the lifting tool and is fixedly connected to it. The lifting tool and the boom are reinforced by the reinforcing ribs. This device conveniently inserts the crossbeam or extension of the lifting tool into the coil material, eliminating the cumbersome process of threading slings, achieving rapid lifting and unloading, greatly saving manpower, reducing overall operation time, and ensuring the safety of lifting as the coil material does not sway or swing during movement due to the pull rope control.

[0004] The aforementioned and existing technologies have the following drawbacks: During the hoisting of coiled steel bars, the horizontal bar of the lifting device passes through the coiled steel bar, and a stop block is used to restrict and limit one side of the coiled steel bar to prevent it from falling off during transportation. However, even with rope control, the lifting device inevitably sways due to inertia during actual transportation. This swaying between the lifting device and the coiled steel bar can cause the one-sided restriction to easily lead to the coiled steel bar sliding on the horizontal bar and colliding with the restriction structure or the lifting device, resulting in deformation and twisting of the coiled steel bar due to compression or impact. Based on this, a coiled steel bar hoisting device is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a coiled steel hoisting device to address the shortcomings of the prior art.

[0006] The technical solution adopted by this utility model is: a coiled steel hoisting device, including a crossbeam and coiled steel bars. A vertical pipe is fixedly mounted on the lower surface of the crossbeam, and a horizontal bar is fixedly mounted on the surface of the vertical pipe. The coiled steel bars are sleeved on the arc surface of the horizontal bar. A lifting ring is fixedly mounted on the upper surface of the crossbeam. A sliding ring is slidably fitted on the arc surface of the horizontal bar. A stop bar is fixedly mounted on the arc surface of the sliding ring. A steel pin slides through the sliding ring. A limiting strip is fixedly mounted on the arc surface of the horizontal bar. The limiting strip is slidably connected to the sliding ring. A plurality of limiting holes are opened on the surface of the limiting strip. The size of the limiting holes is adapted to the size of the steel pin.

[0007] The effect achieved by the above-mentioned components is as follows: by setting two stop bars, the two stop bars can block the two sides of the coiled steel bars when hoisting, thereby preventing the coiled steel bars from sliding during hoisting and avoiding deformation of the coiled steel bars due to squeezing or impact, thus improving the practicality of the hoisting device.

[0008] Preferably, a round rod is fixedly connected to the outer wall of the slip ring, and a baffle is rotatably connected to the arc surface of the round rod, with the upper surface of the baffle abutting against the lower end of the steel pin.

[0009] The effect achieved by the above components is that when the upper surface of the baffle contacts the lower end of the steel pin, the baffle restricts the position of the steel pin and prevents the steel pin from falling off.

[0010] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to a slip ring and a baffle, respectively.

[0011] The effect achieved by the above components is that the baffle can rotate automatically with the help of the torsion spring.

[0012] Preferably, a positioning rod is fixedly connected to the lower surface of the slip ring, and the baffle abuts against the arc surface of the positioning rod.

[0013] The effect achieved by the above components is that when the baffle contacts the positioning rod, the positioning rod restricts the position of the baffle, preventing the baffle from disengaging from the steel pin due to excessive torsion caused by the torsion force of the torsion spring.

[0014] Preferably, a traction rope is fixedly connected to the surface of the steel pin, and the traction rope is fixedly connected to the slip ring.

[0015] The effect achieved by the above components is that the traction rope can prevent the steel pin from being lost after it has been pulled out.

[0016] Preferably, the arc surface of the stop bar is fixedly fitted with a protective sleeve, which is a rubber sleeve.

[0017] The effect achieved by the above components is that the movement of the stop bar will cause the protective sleeve to come into contact with the coiled rebar, and the rubber sleeve material of the protective sleeve can reduce the friction between the coiled rebar and the stop bar.

[0018] Preferably, the arc surface of the crossbar is provided with a plurality of anti-slip grooves.

[0019] The effect achieved by the above components is that the anti-slip groove can increase the friction between the coiled steel bar and the crossbar, further preventing the coiled steel bar from slipping and improving the stability of the coiled steel bar.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model, by setting two stop bars, blocks both sides of the coiled steel bar during hoisting, thereby preventing the coiled steel bar from sliding during hoisting and avoiding deformation due to compression or impact. This improves the practicality of the hoisting device and makes it very convenient to limit the position of coiled steel bars with different numbers of turns. Attached Figure Description

[0030] Example

[0031] Please see Figures 1-4 As shown, this utility model provides a coiled steel lifting device, including a crossbeam 1 and coiled steel bars 17. A vertical pipe 2 is fixedly mounted on the lower surface of the crossbeam 1, and a horizontal bar 3 is fixedly mounted on the surface of the vertical pipe 2. The coiled steel bars 17 are sleeved on the arc surface of the horizontal bar 3. A lifting ring 4 is fixedly mounted on the upper surface of the crossbeam 1. A sliding ring 5 is slidably fitted on the arc surface of the horizontal bar 3. A stop bar 6 is fixedly mounted on the arc surface of the sliding ring 5. A steel pin 7 slides through the sliding ring 5. A limiting strip 8 is fixedly mounted on the arc surface of the horizontal bar 3. The limiting strip 8 is slidably connected to the sliding ring 5. The surface of the limiting strip 8 is open. A number of limiting holes 9 are provided, the size of which is adapted to the size of the steel pin 7. A round rod 10 is fixedly connected to the outer wall of the slip ring 5. A baffle 11 is rotatably connected to the arc surface of the round rod 10. The upper surface of the baffle 11 abuts against the lower end of the steel pin 7. When the upper surface of the baffle 11 contacts the lower end of the steel pin 7, the baffle 11 restricts the position of the steel pin 7 and prevents the steel pin 7 from falling off. A torsion spring 12 is sleeved on the arc surface of the round rod 10. The two ends of the torsion spring 12 are fixedly connected to the slip ring 5 and the baffle 11 respectively. The baffle 11 can rotate automatically with the help of the torsion of the torsion spring 12.

[0032] like Figures 2-4 As shown, a positioning rod 13 is fixedly connected to the lower surface of the slip ring 5. The baffle 11 abuts against the arc surface of the positioning rod 13. When the baffle 11 contacts the positioning rod 13, the positioning rod 13 reaches the position of the baffle 11, preventing the baffle 11 from disengaging from the steel pin 7 due to excessive torsion caused by the torque of the torsion spring 12. A traction rope 14 is fixedly connected to the surface of the steel pin 7. The traction rope 14 is fixedly connected to the slip ring 5. After the steel pin 7 is pulled out, the traction rope 14 can prevent the steel pin 7 from being lost. A protective sleeve 15 is fixedly fitted on the arc surface of the stop rod 6. The protective sleeve 15 is a rubber sleeve. When the stop rod 6 moves, the protective sleeve 15 will contact the coiled steel bar 17. The protective sleeve 15 can reduce the friction between the coiled steel bar 17 and the stop rod 6. Several anti-slip grooves 16 are opened on the arc surface of the crossbar 3. The anti-slip grooves 16 can increase the friction between the coiled steel bar 17 and the crossbar 3, further preventing the coiled steel bar from sliding and improving the stability of the coiled steel bar 17.

[0033] The overall working principle is as follows: When hoisting the coiled rebar 17, the steel cable of the crane or tower crane is passed through the lifting ring 4 and fixed. Then, the crane or tower crane drives the horizontal beam 1 to move. The vertical pipe 2 moves with the horizontal beam 1, which in turn drives the horizontal bar 3 to move. When the horizontal bar 3 moves to a suitable height, it is moved to pass through the coiled rebar 17. At this time, the slip ring 5 is moved, which drives the stop bar 6 to move. When the two stop bars 6 move to both sides of the coiled rebar 17, the horizontal bar 3 moves upward. When the horizontal bar 3 contacts the coiled rebar 17, the slip ring 5 continues to slide along the arc surface of the horizontal bar 3 and the surface of the limiting strip 8. The movement of the slip ring 5 drives the stop bar 6 to move. The movement of the stop bar 6 will cause the protective sleeve 15 to contact the coiled rebar 17. The rubber protective sleeve 15 can reduce the friction between the coiled rebar 17 and the stop bar 6. Then, the baffle 11 is rotated. The baffle 11 rotates along the arc surface of the round bar 10, which will torsion the torsion spring 12. Then, the steel pin 7 is passed through... The slip ring 5 is inserted into the limiting hole 9, and then the baffle 11 will rotate with the help of the torsion spring 12. When the upper surface of the baffle 11 abuts against the lower end of the steel pin 7, the baffle 11 reaches the position of the steel pin 7 to prevent the steel pin 7 from falling off. The steel pin 7 reaches the position of the slip ring 5. When the baffle 11 contacts the positioning rod 13, the positioning rod 13 reaches the position of the baffle 11 to prevent the baffle 11 from being disengaged from the steel pin 7 due to excessive torsion of the torsion spring 12. At this time, the two stops 6 will limit the position of the coiled steel bar 17, which is convenient for subsequent hoisting of the coiled steel bar 17. The anti-slip groove 16 can increase the friction between the coiled steel bar 17 and the crossbar 3, further preventing the coiled steel bar from sliding and improving the stability of the coiled steel bar 17. At the same time, by adjusting the distance between the two stops 6, it is convenient to limit the coiled steel bar 17 with different numbers of turns. After the steel pin 7 is pulled out, the traction rope 14 can prevent the steel pin 7 from being lost.
