Description

Technical Field

[0001] The present invention relates to the technical field of crane hooks, in particular to a construction hoisting sling. Background Art

[0002] In actual construction work, materials usually need to be lifted by cranes. The hook on the crane is an important lifting device. The hook is usually equipped with a pulley to facilitate the steel wire rope passing through the crane to reduce resistance and save effort through the pulley. Especially for construction materials, which are usually heavy, crane lifting needs to ensure safety. The current construction lifting slings are not convenient for testing rope damage, displacement and oil pollution, which may easily cause safety hazards. Manual visual observation is not accurate enough. At the same time, traditional hooks are prone to swinging under the action of inertia during tilted lifting, which may easily cause safety hazards. It is not convenient to perform bottoming friction anti-sway and swing safety detection, nor is it convenient for staff to adjust the hook lifting position.

The safety is improved, and the detection is more comprehensive, which can reduce safety hazards. After a safety problem is detected, the staff can be evacuated in time or the rope can be inspected. The structure is more reasonable. The squeezing block 303 is used in conjunction with the detection protrusion 203 for detection to ensure comprehensive detection. Under the extrusion of the fitting spring piece 205, the bristles on the inner side of the four brush sliders 204 are fitted to the rope. When the rope is partially damaged or produces more greasy impurities, the brush slider 204 will be stuck on the surface of the rope. At this time, the detection connecting plate 201 is driven to rise or fall, and after driving the detection protrusion 203 to press the squeezing block 303, the alarm micro switch 302 is squeezed to control the indicator light 102 above to light up.

[0037] In the embodiment of the present disclosure, the connecting hook part 4 includes: a hook 401 and a friction head 402, the hook 401 is rotatably mounted on the hook mounting frame 101; the friction head 402 is fixedly mounted on the bottom of the hook 401; the hook 401 is a cast iron structure; the friction detection part 5 includes: a friction detection column 501, an anti-false touch spring 502 and a bottom switch 503, the friction detection column 501 is slidably plugged into the hook 401; the anti-false touch spring 502 is sleeved on the bottom of the hook 401; the anti-false touch spring 502 is fixedly mounted on the top of the friction detection column 501, and the end of the anti-false touch spring 502 is connected to the inside of the hook 401; the bottom switch 503 is fixedly mounted on the top of the friction detection column 501, and the bottom switch 503 is located inside the hook 401; four slots are provided at the bottom of the friction detection column 501; the bottom switch 503 is electrically connected to the indicator light 102 in the middle, using The friction detection part 5 can use friction to avoid the situation when directly pulling the connecting hook part 4. If the landing point of the connecting hook part 4 is greatly offset from the end of the boom, the rope will be skewed. At this time, under the action of inertia, the connecting hook part 4 will swing, which may easily cause safety hazards to buildings or manpower. This structure uses friction to improve safety. When the friction detection column 501 contacts the ground, the bottom switch 503 is squeezed, and the indicator light 102 in the middle of the control lights up to prompt. At this time, there is friction between the friction detection column 501 and the ground. When the friction detection column 501 is just separated from the ground, under the action of its own weight, the hook 401 can automatically restore to remain vertical with the end of the boom. However, the gap between the friction detection column 501 and the ground is small, and its displacement distance is limited. During the process, the friction head 402 will also rub against the ground to prevent the hook 401 from swinging.

[0038] In the embodiment of the present disclosure, the hanging position adjustment member 6 includes: a hanging position adjustment plate 601 and a push bolt 602, and the hanging position adjustment plate 601 is fixedly mounted on the inner side of the hook mounting frame 101; the push bolt 602 is threadedly connected to the hanging position adjustment plate 601, and a handwheel is provided at the tail end of the push bolt 602; the hanging position adjustment member 6 also includes: an electromagnet 603, an electromagnet 603 is fixedly mounted on the end of the push bolt 602, and the electromagnet 603 is externally connected to a power supply; the electromagnet 603 is used to magnetically attract the hook 401; the push bolt 602 is used to push the hook 401 for fine-tuning. The use of the hanging position adjustment member 6 can improve the stability of the connecting hook member 4 after the connecting hook member 4 lifts the cargo, and at the same time reduce the wear of the rotating connection between the hook 401 and the hook mounting frame 101. The present structure uses an adjustable push bolt 602, which can be used to fine-tune the position of the electromagnet 603 to limit the hook 401, and can be used to control and adjust the force point when the hook 401 hangs the cargo, avoid long-term local wear, and improve the service life of the hook 401.

[0039] Example 2, based on Example 1, the rope angle prompt part 7 includes: an installation tension spring 701 and a flashlight 702, two installation tension springs 701 are provided, and the two installation tension springs 701 are fixedly installed on the hook mounting frame 101 respectively; a flashlight 702 is fixedly installed between the two installation tension springs 701; a ball head structure is provided on the top of the flashlight 702; the middle part of the flashlight 702 is used to pass the rope; the bottom of the installation tension spring 701 is a conductive structure; the rope angle prompt part 7 also includes: a ball sleeve 703 and a power ring 704, the ball sleeve 703 is sleeved on the power ring 702; the power ring 704 is fixedly installed on the bottom of the ball sleeve 703, and the power ring 704 is connected to the power ring 704. 02; the power supply is connected in series between the power ring 704, the flashlight 702 and the indicator light 102 below. The rope angle prompt part 7 can be used to detect the angle of the rope, which can prevent the rope from being skewed and not being discovered, and can further ensure the practicality of this structure and reduce safety hazards. At the same time, it is also convenient for detecting abnormal shaking of the goods during the lifting process after the goods are lifted, and timely reminding the staff to reduce safety hazards such as being hit. The detection of this structure is simple and reliable. When the rope is tightened, once the rope is skewed or shaken excessively, it will drive the flashlight 702 to contact the power ring 704. At this time, the indicator light 102 below will light up to remind the staff.

[0040] The working principle of this embodiment is as follows: First, the crane rope passes through the four brush sliders 204, passes through the lifting pulley 103 and then passes through the flashlight 702. When the crane controls the rope to move to lift or lower the lifting connector 1, the rope will pass between the four brush sliders 204. Under the squeezing of the fitting spring piece 205, the bristles on the inner side of the four brush sliders 204 are fitted to the rope. When the rope is partially damaged or produces a lot of greasy impurities, the brush slider 204 will be stuck on the rope surface. At this time, the detection connecting plate 201 will be driven to rise or fall, and after driving the detection protrusion 203 to press the squeezing block 303, the alarm micro switch 302 will be squeezed to control the indicator light 102 above to light up. Similarly, when the rope is damaged, the brushes on the inner side of the four brush sliders 204 will be fitted to the rope. When the position is deviated, no matter the direction of the deviated position, as long as the position is excessive, the four brush sliders 204 can be moved horizontally with the detection connecting plate 201. At this time, the end of the detection protrusion 203 is no longer aligned with the end of the extrusion block 303. At this time, the extrusion block 303 is no longer squeezed. At this time, the alarm micro switch 302 can control the indicator light 102 above to light up. When the crane lifts the hook 401, when the hook 401 rises, the friction detection column 501 will be driven, and with the elastic squeezing of the anti-false touch spring 502, the friction detection column 501 can be elastically fitted to the ground. When the friction detection column 501 touches the ground, the bottom switch 503 is squeezed, and the indicator light 102 in the middle is controlled to light up. At this time, the friction detection column 5 01 has friction with the ground, which can control the crane to lift the hook 401. When the friction detection column 501 is just separated from the ground, the hook 401 can automatically recover and remain vertical with the end of the boom under the action of its own weight. However, the gap between the friction detection column 501 and the ground is small, and its displacement distance is limited. During the process, the friction head 402 will also rub against the ground. In this way, after the indicator light 102 in the middle lights up, the hook 401 is gradually lifted up, and the friction between the ground and the friction detection column 501 is used to prevent the hook 401 from swinging. Rotate the push bolt 602 to fine-tune the position of the electromagnet 603. When the hook 401 lifts the ear or strap of the cargo, the electromagnet 603 is turned on to electromagnetically attract the hook 401. At this time The hook 401 remains stable, and the angle of the hook 401 can be changed by rotating the push bolt 602 to fine-tune the position of the electromagnet 603, and it can be adjusted regularly. When lifting goods, as the hook 401 is pulled by the rope, the rope is tensioned. Once the rope is skewed, the flashlight 702 will also be skewed. However, under the action of its own weight, the ball sleeve 703 remains vertical. Once the flashlight 702 is skewed too much, it will contact the contact ring 704. At this time, the indicator light 102 below will light up to alert the staff. Similarly, when the goods shake, the inertial force will also drive the ball sleeve 703 to shake, and the contact ring 704 will easily contact the flashlight 702, and the indicator light 102 below will light up to alert the staff.
