Description

Technical Field

[0001] The utility model relates to the technical field of steel coil lifting, in particular to a vertical steel coil lifting device. Background Art

[0002] During the production and transportation of steel coils, vertical coils are often hoisted because they are most stable when stored upright. Existing vertical coil hoists (such as the tiltable vertical coil clamp disclosed in Application No. 201120213004.X) lack a locking mechanism that allows the two clamps to remain open when not in use. Therefore, when hoisting a vertical coil, the inner clamp arm must first be pulled outward to open the inner and outer jaws, which is quite cumbersome. Furthermore, this clamp structure provides poor clamping performance. Utility Model Content

[0003] The purpose of the present utility model is to overcome the above-mentioned technical deficiencies and propose a vertical steel coil hoist to solve the technical problem that the prior art does not have a locking device so that the two clamps can be in an open state when not working. When lifting the vertical steel coil, it is necessary to pull the inner clamp arm outward first to open the inner and outer jaws, which is more troublesome. In addition, the clamps of this structure have a poor clamping effect.

[0004] To achieve the above technical objectives, the technical solution of the present utility model provides a vertical steel coil sling, comprising:

[0005] bottom beam;

[0006] An upper beam is arranged directly above the bottom beam and can move up and down relative to the bottom beam;

[0007] two clamps, both slidably connected to the bottom beam;

[0008] Two transmission mechanisms, each having its upper end connected to the upper beam and its lower end connected to the two clamps, respectively, so as to convert the up-and-down movement of the upper beam relative to the bottom beam into the two clamps moving closer to or away from each other;

[0009] The locking mechanism has a lower end connected to the bottom beam and an upper end slidably connected to the upper beam. When the upper beam moves downward to the lowest point relative to the bottom beam, the locking mechanism locks the position of the upper beam.

[0010] Furthermore, the bottom beam is a rod-shaped structure and is arranged horizontally.

[0011] Furthermore, the upper beam is a rod-shaped structure and is arranged vertically.

[0012] Furthermore, the two clamps are relatively arranged on the sides of the upper beam, the upper ends of the two clamps are slidably connected to the bottom beam, and the lower ends of the two clamps are used to clamp or loosen the outer wall of the steel coil.

[0013] Furthermore, two guide grooves are provided on the bottom beam, the two guide grooves are arranged opposite to each other and both extend along the length direction of the bottom beam, and the upper ends of the two clamps are respectively slidably arranged in the two guide grooves.

[0014] Furthermore, the two transmission mechanisms are relatively arranged on the sides of the upper beam, and each includes a first force arm and a second force arm. The upper ends of the two first force arms are hinged to the upper end of the upper beam, the upper end of the second force arm is hinged to the lower end of the first force arm, and the lower ends of the two second force arms are respectively hinged to the upper ends of the two clamps.

[0015] Furthermore, the locking mechanism includes a sliding shaft and a connecting rod. The sliding shaft is horizontally arranged and slidably connected to the upper beam. The lower end of the connecting rod is hinged to the bottom beam, and the upper end of the connecting rod is hinged to the sliding shaft. When the upper beam moves downward to the lowest point relative to the bottom beam, the sliding shaft moves to the highest point of the upper beam and is clamped with the upper beam.

[0016] Furthermore, a slide groove is provided on the upper beam, and the slide groove has a first section, a second section and a third section. The first section extends along the length direction of the upper beam, the second section extends along the length direction of the upper beam, and is located above the side of the first section, and the length of the second section is smaller than the length of the first section. The third section is an arc section, and the lower end of the third section is connected with the high end of the first section, and the high end of the third section is connected with the high end of the second section. The sliding shaft is slidably arranged in the slide groove and can move along the length direction of the slide groove. When the upper beam moves downward to the lowest point relative to the bottom beam, the sliding shaft enters the second section and is located at the high end of the second section.

[0017] Furthermore, the vertical steel coil hanger also includes a pushing mechanism, which is arranged on the upper beam and located on one side of the second section, and is used to push the sliding shaft from the high end of the second section into the third section.

[0018] Furthermore, the ejection mechanism includes a push rod and a telescopic driving member. The push rod is horizontally arranged and aligned with the high end of the second section. The telescopic driving member is fixed on the upper beam. The output end of the telescopic driving member is fixedly connected to the push rod so that the push rod can move back and forth in the horizontal direction.

[0019] Compared with the prior art, the beneficial effects of the present invention include: when in use, the upper beam is connected to the lifting rope of the lifting equipment, and the locking mechanism locks the position of the upper beam. At this time, the upper beam and the bottom beam are in a state of being close to each other, and the two clamps are in an open state. When the vertical steel coil needs to be lifted, the lifting equipment drives the entire lifting device to move to the top of the vertical steel coil, and then the lifting equipment drives the entire lifting device downward until the bottom surface of the bottom beam abuts against the upper surface of the vertical steel coil. Then, the locking mechanism on the upper beam is released, and the lifting is carried out. The equipment drives the upper beam to move upward, and the upward movement of the upper beam relative to the bottom beam can be converted into the mutual approach of the two clamps through two transmission mechanisms, and the vertical steel coil is clamped. The lifting equipment continues to drive the upper beam to move upward and lifts the vertical steel coil off the ground, realizing the clamping and transportation of the vertical steel coil. The position of the upper beam is locked by setting a locking mechanism, so that the two clamps can remain open when not working. When lifting the vertical steel coil, there is no need to operate the two clamps to open first, which is very convenient. In addition, the lifting device with this structure has a better clamping effect. BRIEF DESCRIPTION OF THE DRAWINGS

The upper beam 200 is arranged directly above the bottom beam 100 and can move up and down relative to the bottom beam 100; the two clamps 300 are both slidably connected to the bottom beam 100; the upper ends of the two transmission mechanisms 400 are connected to the upper beam 200, and the lower ends of the two transmission mechanisms 400 are respectively connected to the two clamps 300 to convert the up and down movement of the upper beam 200 relative to the bottom beam 100 into the two clamps 300 approaching or moving away from each other; the lower end of the locking mechanism 500 is connected to the bottom beam 100, and the upper end of the locking mechanism 500 is slidably connected to the upper beam 200. When the upper beam 200 moves downward to the lowest point relative to the bottom beam 100, the locking mechanism 500 locks the position of the upper beam 200.

[0026] When in use, the upper beam 200 is connected to the lifting rope of the lifting equipment, and the locking mechanism 500 locks the position of the upper beam 200. At this time, the upper beam 200 and the bottom beam 100 are in a state of being close to each other, and the two clamps 300 are in an open state. When it is necessary to lift the vertical steel coil, the lifting equipment drives the entire sling to move to the top of the vertical steel coil, and then the lifting equipment drives the entire sling downward until the bottom surface of the bottom beam 100 abuts against the upper surface of the vertical steel coil. Then, the locking mechanism 500 on the upper beam 200 is released, and the lifting equipment drives the upper beam 200 upward. The two transmission mechanisms 400 can convert the upward movement of the upper beam 200 relative to the bottom beam 100 into the mutual approach of the two clamps 300, and clamp the vertical steel coil. The lifting equipment continues to drive the upper beam 200 to move upward, and lifts the vertical steel coil off the ground, so as to realize the clamping and transportation of the vertical steel coil. The position of the upper beam 200 is locked by setting the locking mechanism 500, so that the two clamps 300 can remain in an open state when not working.

When the upper beam 200 moves upward relative to the bottom beam 100, the upper ends of the two first force arms 410 are driven. When the upper beam 200 moves downward relative to the bottom beam 100, the upper ends of the two first force arms 410 will move downward synchronously. At this time, the lower ends of the two first force arms 410 will rotate outward synchronously, thereby driving the two second force arms 420 to move outward synchronously, so that the two clamps 300 are close to each other.

The pushing mechanism 600 is started to push the sliding shaft 510 The high end of the second section 212 is pushed into the third section 213 to release the lock on the upper beam 200. Then, the lifting equipment drives the upper beam 200 to move upward, and the sliding shaft 510 moves downward along the third section 213 and enters the first section 211. The sliding shaft 510 continues to move downward along the first section 211. During this process, through the transmission action of the two first force arms 410 and the two second force arms 420, the two clamps 300 approach each other and clamp the vertical steel coil.

[0037] In order to better understand the present invention, the following Figure 1 - Figure 3 The working principle of the technical solution of the utility model is described in detail:

[0038] When in use, the upper beam 200 is connected to the lifting rope of the lifting equipment, and the sliding shaft 510 is located at the lower end of the second section 212. Since the lifting rope provides an upward pulling force to the upper beam 200, the bottom beam 100 tends to move downward due to its own gravity. At this time, the sliding shaft 510 tends to move downward and is abutted by the upper beam 200, so that the upper beam 200 and the bottom beam 100 are locked, and the two clamps 300 remain in an open state. When the vertical steel coil needs to be lifted, the lifting After the lifting equipment drives the entire sling to move to the top of the vertical steel coil, the lifting equipment drives the entire sling to move downward until the bottom surface of the bottom beam 100 abuts against the upper surface of the vertical steel coil. Then, the lifting equipment continues to drive the upper beam 200 to move downward. At this time, the sliding shaft 510 moves upward along the second section 212 and reaches the high end of the second section 212. The telescopic driving member 620 is started, and the telescopic driving member 620 pushes the push rod 610 to move toward the direction close to the sliding shaft 510, and the sliding shaft 510 is moved upward. 10 is pushed into the third section 213 to release the lock on the upper beam 200. Then, the lifting equipment drives the upper beam 200 to move upward, and the sliding shaft 510 moves downward along the third section 213 and enters the first section 211. The sliding shaft 510 continues to move downward along the first section 211. During this process, through the transmission action of the two first force arms 410 and the two second force arms 420, the two clamps 300 approach each other and clamp the vertical steel coil. The sliding shaft 510 stops at the first The section 211 continues to move downward, and the upper beam 200 and the bottom beam 100 are locked again. The lifting equipment drives the entire sling to move upward, and lifts the vertical steel coil off the ground and reaches the preset position, thereby realizing the clamping and transportation of the vertical steel coil. The position of the upper beam 200 is locked by setting the locking mechanism 500, so that the two clamps 300 can remain in an open state when not working. When lifting the vertical steel coil, there is no need to operate the two clamps 300 to open first, which is very convenient. In addition, the sling with this structure has a better clamping effect.

[0039] The utility model provides a vertical steel coil sling with the following beneficial effects:

[0040] (1) After the lifting equipment drives the entire sling to move directly above the vertical steel coil, the lifting equipment then drives the entire sling downward until the bottom surface of the bottom beam 100 abuts against the upper surface of the vertical steel coil. Then, the lifting equipment continues to drive the upper beam 200 downward. At this time, the sliding shaft 510 moves upward along the second section 212 and reaches the high end of the second section 212. The telescopic drive member 620 is started, and the telescopic drive member 620 pushes the push rod 610 toward the direction close to the sliding shaft 510, pushing the sliding shaft 510 into the third section 213, thereby releasing the lock on the upper beam 200.

[0041] (2) After the vertical steel coil is transferred to the preset position, the lifting equipment drives the upper beam 200 to move downward, the sliding shaft 510 moves upward along the first section 211, enters the third section 213, and then enters the second section 212. During this process, through the transmission action of the two first force arms 410 and the two second force arms 420, the two clamps 300 move away from each other and release the vertical steel coil. The lifting equipment then drives the upper beam 200 to move upward, the sliding shaft 510 moves downward along the second section 212, and reaches the lower end of the second section 212. The upper beam 200 continues to move upward, and the bottom beam 100 tends to move downward due to its own gravity. At this time, the sliding shaft 510 tends to move downward and is abutted by the upper beam 200, so that the upper beam 200 and the bottom beam 100 are locked, so that the two clamps 300 remain in an open state.

[0042] (3) By setting the locking mechanism 500 to lock the position of the upper beam 200, the two clamps 300 can remain in an open state when not in operation. When lifting a vertical steel coil, there is no need to operate the two clamps 300 to open first, which is very convenient. In addition, the lifting device of this structure has a better clamping effect.
