Description

Technical Field

[0001] The present invention relates to the technical field of crane shackles, and in particular to a crane shackle for large pipe truss hoisting construction. Background Technique

[0002] In actual large pipe truss hoisting construction work, large pipe trusses need to be hoisted with the cooperation of a crane and a shackle. Among them, the shackle is an important connecting component. Usually, the shackle is composed of a horseshoe bar and a bolt. Usually, large trusses need to be bundled with straps and then connected to the shackle. The conventional operation is to sleeved the end of the strap on the shackle bolt, then bundle the strap on the truss, pass the strap through the inside of the shackle horseshoe bar, and then connect the crane for hoisting work, or directly use the shackle to butt against the truss. The current crane shackle for large pipe truss hoisting construction is not convenient for preventing the bolt from being tightened. After the bolt is tightened excessively, the shackle bears a large force, and it is easy to cause problems such as difficulty in subsequent disassembly due to slight deformation. At the same time, if the bolt is directly loosely installed, it is easy to loosen, and it is not convenient to detect the deformation safety of the shackle in real time, not convenient to understand the service life of the shackle, and easy to cause potential safety hazards.

[0022] Among them, the shackle mounting member 1 includes: a shackle bolt 102, a limiting ring 1021, a limiting bolt 103, and a rotating friction column 104. The shackle bolt 102 is inserted into a through hole on the side of the shackle horseshoe rib 101, and the end of the shackle bolt 102 is threadedly connected to an internal thread hole on the other side of the shackle horseshoe rib 101; a limiting ring 1021 is fixedly sleeved on the shackle bolt 102; a limiting bolt 103 is threadedly connected to the shackle bolt 102; a rotating friction column 104 is slidably inserted into the shackle bolt 102, and a spring is provided at the bottom of the rotating friction column 104; the spring at the bottom of the rotating friction column 104 is connected to the shackle bolt 102; the top of the rotating friction column 104 is a hemispherical structure; gaps are respectively provided between the through holes and the internal thread holes on both sides of the shackle bolt 102 and the shackle horseshoe rib 101; the swing control member 2 includes: a swing cylinder 201 and a rotating groove 2011. The swing cylinder 201 is rotatably sleeved on the shackle bolt 102; the end of the swing cylinder 201 is an octagonal structure; the swing cylinder 201 is located between the limiting ring 1021 and the limiting bolt 103; a circle of rotating grooves 2011 is provided on the inner side of the swing cylinder 201, and a circle of rotating grooves 2011 are respectively arc-shaped structures; the end of the rotating friction column 104 is attached to the rotating groove 2011; the stop plugging member 3 includes: a stop mounting cylinder 301, a protective spring 3011, a plugging disc 302, a plugging column 3021, and an indicator light 303. The stop mounting cylinder 301 is threadedly connected to the shackle horseshoe rib 101; the stop mounting cylinder 301 is located at the threaded end of the shackle bolt 102; a protective spring 3011 is fixedly installed inside the stop mounting cylinder 301; a plugging disc 302 is slidably installed on the stop mounting cylinder 301; the end of the protective spring 3011 is connected to the plugging disc 302; a plugging column 3021 is fixedly installed on the plugging disc 302; the end of the plugging column 3021 is plugged into the threaded end of the shackle bolt 102;An indicator light 303 is fixedly sleeved on the stop mounting cylinder 301. By using the stop connector 3 and the rotary control member 2, it is possible to prevent the shackle bolt 102 from being tightened excessively, which can improve the safety of using this structure and reduce the situation where the thread is jammed due to excessive force on the shackle bolt 102 resulting in minor deformation. It can also improve the flexibility of disassembling and assembling the shackle bolt 102 in this structure. The elastic stop can be achieved by using the stop mounting cylinder 301. The structure is simple to operate. During the tightening process of the shackle bolt 102, excessive tightening pressure can be avoided. The rotating friction column 104 can elastically retract, preventing the operator from continuously rotating and tightening, thus realizing the tightening protection work. The structure is simple to operate and is consistent with the traditional way of using a shackle. After putting the end of the strap used for the shackle on the shackle bolt 102, insert the shackle bolt 102 into the shackle horseshoe rib 101, and hold the rotary cylinder 201 to rotate the shackle bolt 102. At this time, the shackle bolt 102 will be screwed into the shackle horseshoe rib 101 using the thread. As the shackle bolt 102 is screwed into the shackle horseshoe rib 101, the end of the shackle bolt 102 can be inserted into the insertion column 3021, and the insertion column 3021 is used to limit the insertion of the shackle bolt 102. At the same time, as the shackle bolt 102 is screwed in, the end of the shackle bolt 102 can abut against the side of the insertion disc 302, and the protective spring 3011 is compressed. At this time, the shackle bolt 102 is not fully tightened, but under the elastic extrusion and block of the protective spring 3011, when the rotary cylinder 201 is rotated, the shackle bolt 102 cannot move forward continuously. At this time, the extrusion force of the rotating groove 2011 on the rotating friction column 104 increases, and the rotating friction column 104 will retract after being pressed. The spring at the bottom of the rotating friction column 104 will be compressed. The rotating friction column 104 can slide on one circle of the rotating groove 2011 to prevent the tightening force of the shackle bolt 102 from being too large.;

[0023] Among them, the anti-loosening and anti-detaching part 4 includes: an anti-loosening sliding sleeve 401 and a stop post 4011. The inner side of the anti-loosening sliding sleeve 401 is an octagonal hole; the anti-loosening sliding sleeve 401 is slidably sleeved on the rotary cylinder 201; a circle of stop posts 4011 is fixedly installed at the end of the anti-loosening sliding sleeve 401, and the circle of stop posts 4011 are respectively attached to the side surfaces of the limit ratchet-shaped blocks 1011; the limit ratchet-shaped blocks 1011 are used for unidirectional limiting of the stop posts 4011; the anti-loosening and anti-detaching part 4 further includes: a positioning spring 402. The positioning spring 402 is fixedly installed at the end of the anti-loosening sliding sleeve 401, and the positioning spring 402 is sleeved on the rotary cylinder 201; the end of the positioning spring 402 is connected to the rotary cylinder 201; by using the anti-loosening and anti-detaching part 4, on the basis of preventing the shackle bolt 102 from being tightened excessively, the shackle bolt 102 can be prevented from falling off, and it can play a role in unidirectional limiting and anti-detaching. When the staff operates to install the shackle bolt 102, it can be limited and attached. When the shackle bolt 102 is rotated and installed, it will not be locked in cooperation with the limit ratchet-shaped block 1011. Only when the shackle bolt 102 is rotated outward for disassembly can positioning be achieved, which can improve the safety of using this structure. When the shackle bolt 102 is rotated and installed on the shackle horseshoe rib 101, rotating the rotary cylinder 201 will also drive the anti-loosening sliding sleeve 401 to rotate together. Under the extrusion of the positioning spring 402, the anti-loosening sliding sleeve 401 can be attached to the side surface of the limit ratchet-shaped block 1011 and slide in real time. By using the ratchet-shaped structure of the limit ratchet-shaped block 1011, when the shackle bolt 102 is tightened, the stop post 4011 will not cause jamming. On the contrary, when the rotary cylinder 201 is rotated and disassembled, the limit ratchet-shaped block 1011 is used for limiting and jamming, which can prevent loosening during actual lifting and transportation.

[0024] Among them, the connecting limit member 5 includes: a connecting limit shaft 501, a connecting cylinder 502, a lifting cylinder 503, and a displacement spring 504. There are two connecting limit shafts 501, and both ends of the two connecting limit shafts 501 are bevel structures; the two connecting limit shafts 501 are respectively inserted into the two positioning inclined slots 1012; a connecting cylinder 502 is fixedly installed between the two connecting limit shafts 501; a lifting cylinder 503 is slidably installed on the connecting cylinder 502; a displacement spring 504 is sleeved inside the lifting cylinder 503; the two positioning inclined slots 1012 are used to position the connecting limit shaft 501; the connecting limit member 5 further includes: a power connection ring 505, and the power connection ring 505 is fixedly embedded inside the lifting cylinder 503; the power connection ring 505 is a copper conductive structure. The connecting limit member 5 can be used to limit the strap of the shackle, which can improve the safety of the strap used in this structure. At the same time, by using the way that the connecting limit shaft 501 is located between the shackle horseshoe ribs 101, the standardization of the shackle strap use can be improved, and it can prevent the staff from putting the end of the strap on the shackle horseshoe rib 101, while the strap passes through the shackle bolt 102. If the strap shakes frequently when hoisting goods, the strap is likely to rub against the shackle bolt 102 and cause loosening, which can improve the safety of this structure and ensure that the end of the shackle strap is sleeved on the shackle bolt 102 to meet the hoisting construction standard. Otherwise, the strap cannot be installed, and the structure is safer. With this structure, when installing the shackle strap, the end of the strap can only be sleeved on the shackle bolt 102, and then the strap is wound around the pipe truss, and the other end of the strap passes through between the shackle horseshoe rib 101 and above the connecting limit member 5.

[0025] Embodiment 2. On the basis of Embodiment 1, the shackle detection member 6 includes: a detection sliding shaft 601, a limit groove block 602 and a positioning bolt 603. The detection sliding shaft 601 is slidably inserted into the lifting cylinder 503; a limit groove block 602 is fixedly installed at the bottom of the detection sliding shaft 601, and both sides of the bottom of the limit groove block 602 are inclined surface structures; the limit groove block 602 is used to fit the pipe truss strap; a displacement spring 504 is connected between the detection sliding shaft 601 and the lifting cylinder 503; the positioning bolt 603 is threadedly connected to the connection cylinder 502; the end of the positioning bolt 603 is used to squeeze and position the lifting cylinder 503; the shackle detection member 6 further includes: a power connection elastic sheet 604, a power connection elastic sheet 604 is fixedly installed on the detection sliding shaft 601, and the power connection elastic sheet 604 is used to fit the power connection ring 505; the power connection elastic sheet 604, the power connection ring 505 and the indicator light 303 are connected in series to the power supply. The shackle detection member 6 can be used to detect the deformation of the shackle, which can avoid the over - deformation of the shackle not being detected and affecting the use safety. At the same time, it ensures that the service life of the shackle can be monitored, reduces safety hazards such as fracture, and can also assist in testing the stable installation and dimensional accuracy of the shackle strap. The structure is more reasonable, can be directly detected, and is compact, which can avoid affecting the use safety and flexibility of this structure. The shackle detection member 6 can be adapted to the shackle strap. Once the shackle bolt 102 is bent or the shackle strap becomes thinner due to wear, at this time, under the extrusion of the displacement spring 504, the detection sliding shaft 601 will move downward to drive the limit groove block 602 to fit. Once the deformation size is too large, at this time, the power connection elastic sheet 604 will be misaligned and separated from the power connection ring 505, and the indicator light 303 will turn off to give a prompt. Similarly, if the shackle horseshoe tendon 101 expands outward due to long - term use and the deformation size increases, at this time, the gap between the two positioning inclined grooves 1012 and the ends of the two connection limit shafts 501 increases, generating play. At this time, under the extrusion of the displacement spring 504, the connection limit shaft 501 will move upward, and the corresponding power connection elastic sheet 604 will be misaligned and separated from the power connection ring 505, and the indicator light 303 will turn off to give a prompt, ensuring the comprehensiveness of deformation detection.

[0026] Working principle of this embodiment: First, when installing the shackle strap, the end of the strap can only be sleeved on the shackle bolt 102. Then, wind the strap around the pipe truss, and pass the other end of the strap through the space between the shackle horseshoe rib 101 and above the connecting limit piece 5. After the end of the strap used for the shackle is sleeved on the shackle bolt 102, insert the shackle bolt 102 into the shackle horseshoe rib 101, and hold the rotary cylinder 201 to rotate the shackle bolt 102. At this time, the shackle bolt 102 will be screwed into the shackle horseshoe rib 101 using the thread. As the shackle bolt 102 is screwed into the shackle horseshoe rib 101, the end of the shackle bolt 102 can be inserted into the plug post 3021 to perform plug-in limit on the shackle bolt 102. At the same time, as the shackle bolt 102 is screwed in, the end of the shackle bolt 102 can abut against the side of the plug-in disc 302, and the protective spring 3011 is compressed. At this time, the shackle bolt 102 is not fully tightened, but under the elastic extrusion and block of the protective spring 3011, when rotating the rotary cylinder 201, the shackle bolt 102 cannot continue to move forward. At this time, the extrusion force of the rotating groove 2011 on the rotating friction column 104 increases, and the rotating friction column 104 will retract after being pressed, and the spring at the bottom of the rotating friction column 104 will be compressed. The rotating friction column 104 can slide on one circle of the rotating groove 2011 to prevent the tightening force from being too large. On the contrary, when disassembling the shackle bolt 102, without the block of the protective spring 3011, the rotating friction column 104 can be inserted into the rotating groove 2011 by the extrusion force of the lower spring. Using this frictional force, the rotary cylinder 201 can be rotated to drive the disassembly of the shackle bolt 102. When the shackle bolt 102 is deformed and a large force is required for disassembly, the limit bolt 103 is connected to the wrench, and rotating the limit bolt 103 can disassemble the shackle bolt 102. When the shackle bolt 102 is rotated and installed on the shackle horseshoe rib 101, rotating the rotary cylinder 201 will also drive the anti-drop sliding sleeve 401 to rotate together. Under the extrusion of the positioning spring 402, the anti-drop sliding sleeve 401 can be in real-time contact with the side of the limit ratchet block 1011 and slide. Using the ratchet structure of the limit ratchet block 1011, when the shackle bolt 102 is tightened, the stop post 4011 will not cause jamming. On the contrary, when rotating and disassembling the rotary cylinder 201, under the extrusion of the positioning spring 402, the anti-drop sliding sleeve 401 drives the stop post 4011 to fit on the limit ratchet block 1011, and the limit ratchet block 1011 can be used for limit jamming to prevent loosening during actual lifting. When it is necessary to disassemble the shackle bolt 102, it is necessary to manually pull the anti-drop sliding sleeve 401 backward to squeeze the positioning spring 402, driving the stop post 4011 to separate from the limit ratchet block 1011 to prevent jamming;After the end of the strap is installed on the shackle bolt 102, slide the lifting cylinder 503 to drive the limit groove block 602 on the lifting cylinder 503 to fit on the strap. At the same time, the lifting cylinder 503 can continue to slide to drive the detection slide shaft 601 to compress the displacement spring 504. At this time, the detection slide shaft 601 can drive the power connection elastic piece 604 to move and fit on the power connection ring 505. At this time, the indicator light 303 lights up to give a prompt, and then the positioning bolt 603 can be tightened to squeeze the positioning lifting cylinder 503. Subsequently, once the shackle bolt 102 is bent or deformed, or the shackle strap becomes thinner due to wear, at this time, under the extrusion of the displacement spring 504, the detection slide shaft 601 will move downward to drive the limit groove block 602 to fit and match. Once the deformation size is too large, at this time, the power connection elastic piece 604 will be misaligned and separated from the power connection ring 505, and the indicator light 303 can turn off to give a prompt. Similarly, if the shackle horseshoe tendon 101 is outwardly expanded and the deformation size increases due to long-term use, at this time, the gap between the two positioning inclined grooves 1012 and the ends of the two connecting limit shafts 501 increases, resulting in play. At this time, under the extrusion of the displacement spring 504, the connecting limit shaft 501 will move upward, and the corresponding limit groove block 602 will fit on the strap.
