Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated beam plate hoisting, and in particular relates to an adjustable tensioning type hoisting device for corrugated beam plates. Background Art

[0002] In the production and processing of stainless steel guardrails, the lifting and transportation links play a vital role. Due to the fixed structure of traditional lifting equipment, it is difficult to adapt to the diverse length requirements of corrugated beams, resulting in the need to frequently replace the lifting equipment during operations. This not only increases the construction cost burden, but also significantly reduces the overall construction efficiency. In addition, when using rope lifting, the sharp edges and corners of the guardrail directly act on the slings or lifting belts, which can easily cause serious wear and even breakage of the wire rope. Even with the protection of pads, the operation is still cumbersome, and irregular operations during the binding process, such as dragging the slings, deviation of the center of gravity, and loose binding, all pose potential safety hazards that cannot be ignored.

[0003] In response to the above-mentioned lifting difficulties, although some adjustable length hoists have appeared on the market, they still have shortcomings in terms of adjustment accuracy, stability, ease of operation and economic applicability. In addition, the original design was not specifically aimed at the lifting needs of guardrails, so there are many limitations in actual applications. Utility Model Content

[0039] An upper driven gear 24 and a detachable upper handle 25 are fixedly provided at the front end of the rotating shaft of the outer rope reel 5. The upper driven gear 24 and the upper handle 25 are both located in front of the front fixed plate 23.

[0040] A lower driven gear 26 and a detachable lower handle 27 are fixedly provided at the front end of the rotating shaft of the inner pull rope reel 7. The lower driven gear 26 and the lower handle 27 are both located in front of the front fixed plate 23.

When the upper brake lock block 34 on the upper sliding rod slides to fit with the upper brake gear 33, the upper brake gear 33 cannot continue to rotate, thereby preventing the outer rope drum 5 from continuing to rotate. When the upper brake lock block 34 on the upper sliding rod slides to disengage from the upper brake gear 33, the upper brake gear 33 can continue to rotate, thereby allowing the outer rope drum 5 to continue to rotate.

When the lower brake lock block 36 on the lower sliding rod slides to fit with the lower brake gear 35, the lower brake gear 35 cannot continue to rotate, thereby preventing the inner rope drum 7 from continuing to rotate. When the lower brake lock block 36 on the lower sliding rod slides to disengage from the lower brake gear 35, the lower brake gear 35 can continue to rotate, thereby allowing the inner rope drum 7 to continue to rotate.

[0047] The working principle of the utility model is:

[0048] Step 1: When the corrugated beam plate 37 needs to be hoisted, first slide the driving gear 28 to engage with the transition gear 30 and the lower driven gear 26, and at the same time slide the lower brake lock block 36 and the upper brake lock block 34 to disengage from the lower brake gear 35 and the upper brake gear 33 respectively.

[0049] Step 2: The active handle 29 is rotated forward, and the active handle 29 drives the active gear 28 to rotate forward. The lower driven gear 26 and the transition gear 30 rotate in the opposite direction to the active gear 28, and the upper driven gear 24 rotates in the same direction as the active gear 28. In this way, the upper driven gear 24 rotates in the opposite direction to the lower driven gear 26, so that the outer rope drum 5 rotates in the opposite direction to the inner rope drum 7. The outer rope drum 5 drives the two outer ropes 6 to be wound around the outer rope drum 5, and the two tightened outer ropes 6 drive the two moving seats 3 to move away from each other. The rotating inner rope drum 7 gradually releases the two inner ropes 8, and the released two inner ropes 8 move synchronously with the two moving seats 3, so that the released two inner ropes 8 are also in a taut state. When the distance between the two hanging claws 4 is greater than the length of the corrugated beam plate 37, the active handle 29 is stopped from rotating.

[0050] Step 3: Move the hoisting device as a whole to the corrugated beam plate 37, at which time the two lifting claws 4 are located at the two ends of the corrugated beam plate 37. Then rotate the active handle 29 in the opposite direction, so that the outer rope drum 5 and the inner rope drum 7 start to rotate in the opposite direction, and the inner rope drum 7 drives the two inner ropes 8 to gradually wrap around the inner rope drum 7, and the two tightened inner ropes 8 drive the two moving seats 3 to gradually approach. The outer rope drum 5 gradually releases the two outer ropes 6, and the released two outer ropes 6 move synchronously with the two moving seats 3, so that the released two outer ropes 6 are also in a taut state. In this process, the horizontal sections 20 of the L-shaped rods 18 of the two lifting claws 4 move to the lower sides of the two ends of the corrugated beam plate 37, until the vertical sections 19 of the L-shaped rods 18 of the two lifting claws 4 contact the two ends of the corrugated beam plate 37, and then stop rotating the active handle 29.

[0051] Step 4: Slide the lower brake lock block 36 and the upper brake lock block 34 until they are respectively engaged with the lower brake gear 35 and the upper brake gear 33, so as to prevent the outer rope drum 5 and the inner rope drum 7 from rotating, ensuring that the distance between the two moving seats 3 will not change unexpectedly.

[0052] Step 5: Lift the hoisting beam 1 as a whole, and the horizontal sections 20 of the multiple L-shaped rods 18 of the two lifting claws 4 are in contact with the multiple wave crests at both ends of the lower end surface of the corrugated beam plate 37, respectively, and the corrugated beam plate 37 is supported and fixed by the two lifting claws 4. In this way, the corrugated beam plate 37 can be hoisted smoothly.

[0053] Step 6: After the lifting beam 1 moves the corrugated beam plate 37 to the designated location, the active handle 29 is rotated forward again, so that the two moving seats 3 drive the two lifting claws 4 to move away from each other, thereby lowering the corrugated beam plate 37 to the designated location.

[0054] Step 7: Repeat the above steps 1 to 6 to lift different corrugated beam plates 37.

[0055] Step 8: After the sling has been working for a period of time, the driving gear 28 is slid outward to be disengaged from the lower driven gear 26 and the transition gear 30, and then the upper handle 25 is fixed to the rotating shaft of the outer rope drum 5, and the lower handle 27 is fixed to the rotating shaft of the inner rope drum 7, and the outer rope drum 5 and the inner rope drum 7 are controlled to rotate respectively, so that the loose outer rope 6 and the inner rope 8 are re-tightened. Then the driving gear 28 is re-engaged with the lower driven gear 26 and the transition gear 30.

[0056] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
