Description

Technical Field

[0001] The present application relates to the technical field of engineering technology, and in particular to a torsion block hoist and a hoisting method. Background Art

[0002] Twist block is a kind of prefabricated concrete block. Due to its special shape, it is easy to form a node when placed on a slope, which increases the stability of the slope. It is often used for the outer layer protection of breakwaters, coasts and other slopes. This structure can effectively slow down the scouring and erosion of the slope by water flow.

[0003] Reference Figure 1 In the prior art, the twist block 7 includes a middle portion 71 and side portions 72. The middle portion 71 is in the shape of a long strip, and the width of the middle portion 71 gradually decreases from the middle position to the two sides to form an arc surface 73; the side portions 72 are provided with two and symmetrically distributed on both sides of the middle portion 71, the shape of the middle portion 71 is adapted to the shape of the side portions 72, the length direction of the middle portion 71 is perpendicular to the length direction of the side portions 72, and the two ends of the middle portion 71 and the two ends of the two side portions 72 form overlapping points for overlapping on the slope. When such a twist block 7 is hoisted to the installation position of the slope such as the coast, the usual practice is: use a truck to transport the twist block 7 to the site, then tie the two ends of the middle portion 71 with a sling, and then hoist the sling with a crane, so that the twist block 7 can be hoisted and transferred to the designated position on the slope.

[0004] However, during the process of hoisting and lowering such twist king blocks, since the slope of the coast has a certain inclination angle, when the twist king block is lifted and landed, it is necessary to manually continuously fine-tune the falling angle of the twist king block to successfully place the twist king block on the inclined slope. The construction efficiency is low and it consumes a lot of manpower and material resources. At the same time, the manual assistance method also has certain safety hazards, so it needs further improvement. Summary of the invention

[0005] In order to improve the work efficiency of placing the twist king block, the present application provides a twist king block hoist and a hoisting method.

[0006] In the first aspect, the present application provides a torsion block hanger adopting the following technical solution: A torsion block hanger comprises a hanger, a first lifting chain group and a second lifting chain group, the first lifting chain group comprises two first chains, the two first chains are respectively arranged at the two ends of the hanger, the two ends of the first chain are connected to the hanger, the first chain and the hanger are combined to form a restraining area for restraining a middle part, the hanger is connected to the two ends of the middle part through the two first chains; the second lifting chain group comprises two second chains, the two second chains are respectively arranged at the two ends of the hanger, one end of the second chain is connected to the hanger, and the other end is used to connect to the crane, and the lengths of the two second chains are set to be different.

[0007] By adopting the above technical solution, through the arrangement of the hanger, the first lifting chain group and the second lifting chain group, both ends of the first chain are connected to the hanger, thereby forming a ring-shaped restraining area with the hanger for the middle part of the twist block to pass through, and the hanger is connected to the two ends of the middle part through the two first chains respectively, so that the hanger is connected to the middle part; the hanger is connected to the crane through the two second chains respectively, and the crane is started, and the hanger can be lifted by the two second chains, thereby lifting the twist block; in actual application, according to the inclination angle of the slope, the two second chains are calculated By setting two second chains of different lengths, when the twist king block is hoisted, the two second chains of different lengths can make the hanger inclined, that is, the twist king block is forced to be inclined after being hoisted to adapt to the inclination angle of the slope (in the inclined twist king block, the overlapping points on the lower side of the middle part and the overlapping points on the lower sides of the two side parts, and the plane formed by the combination of the three overlapping points remain parallel to the slope), so that when the twist king block is transferred to the installation position and lowered, there is no need to manually fine-tune the falling angle of the twist king block, thereby improving the work efficiency of the twist king block placement.

[0008] Optionally, the hanger includes a connecting rod and two clamps, the two clamps are respectively arranged at both ends of the connecting rod, the two clamps are arranged corresponding to the two first chains, and both ends of each of the first chains are connected to the corresponding clamp; when one end of the middle part is passed through the restraining area, the bottom wall of the clamp abuts against the arc surface of the middle part.

[0009] By adopting the above-mentioned technical solution, through the setting of the connecting rod and the two clamping plates, the connecting rod and the two clamping plates are combined to form an "I-shape", and the two clamping plates are used for the installation of the two first chains, so that the two first chains can be respectively bound at the two ends of the middle part; when the twist king block is lifted, the two clamping plates respectively abut against the arc-shaped surface of the twist king block, and cooperate with the first chain to limit the middle block, so that the twist king block can be lifted.

[0010] Optionally, a limiting rod is arranged between the connecting rod and one of the clamping plates, and both ends of the limiting rod are extended along the thickness direction of the middle part, and the two ends of the limiting rod respectively support the arcuate surfaces of the two side parts; when the clamping plate abuts against the arcuate surface of the middle part, there is a gap between the limiting rod and the arcuate surface of the middle part.

[0011] By adopting the above-mentioned technical scheme, through the setting of the limit rod, after the torsion block is lifted, due to the two second chains of different lengths, the hanger as a whole is in an inclined state, and then the torsion block is in an inclined state. In this state, the limit rod can support the arc-shaped surfaces of the two sides to prevent the possibility of the torsion block sliding down along the inclined angle, thereby improving the stability of the torsion block during the lifting process; on the other hand, during lifting, the clamping plate abuts against the arc-shaped surface of the middle part. At this time, there is a gap between the limit rod and the arc-shaped surface of the middle part, thereby isolating the limit rod and the arc-shaped surface of the middle part, reducing the possibility of the limit rod contacting the arc-shaped surface of the middle part, which causes the clamping plate to warp, thereby improving the restraining effect of the combination of the clamping plate and the first chain on the middle part.

[0012] Optionally, a first connecting lock and a movable ring are respectively provided at both ends of the first chain, and a connecting groove for hanging the first connecting lock and a movable groove for hanging the movable ring are respectively opened on the plate surface of the pallet, and the connecting groove and the movable groove are respectively arranged on both sides of the pallet; one side of the movable groove penetrates the side wall of the pallet and forms an inlet and outlet of the movable groove, and the height of the movable groove gradually decreases from the side close to the inlet and outlet to the side away from the inlet and outlet.

[0013] By adopting the above technical solution, through the arrangement of the first connecting lock and the movable ring, one end of the first chain is connected to the connecting groove of the card plate through the first connecting lock, and then the other end of the first chain is arranged around the middle part and hung on the movable groove of the card plate through the movable ring, so that the first chain and the card plate are combined to form a restraining area restrained in the middle part, so that the twist king block can be lifted; the movable groove gradually decreases in height from the side close to the inlet and outlet to the side away from the inlet and outlet, so that during the lifting process of the twist king block, the possibility of the movable ring falling off can be reduced, and the connection stability between the first chain and the card plate is improved; after the twist king block is transferred to the specified position and falls, the movable ring is pulled and forced to be out of the movable groove, so that the first chain can be released, thereby improving the convenience of disassembly and assembly between the first chain and the middle part.

[0014] Optionally, the card plate is connected to a hanging plate, and one end of the second chain is connected to the hanging plate; the card plate is provided with a limit stop hook, and the limit stop hook is rotatably installed on the card plate for opening and closing the inlet and outlet of the movable slot; a linkage component is provided between the second chain and the limit stop hook, and the limit stop hook normally opens the inlet and outlet of the movable slot. When the second chain is tightened to lift the hanger, the linkage component drives the limit stop hook to rotate and close the inlet and outlet of the movable slot.

[0015] By adopting the above-mentioned technical scheme, through the arrangement of the limit stop hook and the linkage assembly, the first chain is wound around the middle part and the movable ring of the first chain is hung on the movable groove, and then the second chain is lifted by a crane to lift the torsion block; when the second chain is tightened, the linkage assembly can drive the limit stop hook to rotate, thereby blocking the inlet and outlet of the movable groove to close the inlet and outlet, reducing the possibility of the movable ring of the torsion block being separated from the movable groove during the lifting process, improving the stability of the overall structure, and improving operation safety.

[0016] Optionally, the linkage assembly includes a linkage block and a linkage rod, the hanging plate is provided with a sliding groove, the linkage block is slidably installed in the sliding groove, one end of the second chain is connected to the linkage block, and the second chain is connected to the hanging plate through the linkage block; one end of the linkage rod is hinged to the linkage block, and the other end is hinged to the limit stop hook; the sliding groove has a first point position and a second point position, the first point position is located below the second point position, the linkage block normally falls to the first point position of the sliding groove and the limit stop hook opens the inlet and outlet of the movable groove; when the second chain is tightened to lift the hanging plate, the linkage block moves up to the second point position, and the limit stop hook closes the inlet and outlet of the movable groove.

[0017] By adopting the above-mentioned technical scheme, through the setting of the linkage block and the linkage rod, under normal circumstances, the linkage block is located at the first point of the sliding groove, and the limit stop hook opens the inlet and outlet of the movable groove; when the crane lifts the second chain to tighten the second chain, the second chain can pull the linkage block, forcing the linkage block to move up to the second point of the sliding groove, and the linkage block pulls the limit stop hook to rotate through the linkage rod, forcing the limit stop hook to block the inlet and outlet of the movable groove, thereby keeping the movable ring hooked in the movable groove, thereby improving the stability of the connection between the movable ring and the clamping plate.

[0019] By adopting the above-mentioned technical solution, through the setting of the moving block and the tensioning assembly, the crane lifts the second chain, forcing the limit stop hook to rotate and close the inlet and outlet of the movable groove. At this time, the tensioning assembly drives the moving block to move toward the side close to the movable groove, and the end of the first chain away from the movable ring is connected to the moving block, so that the two ends of the first chain can approach each other, thereby reducing the size of the restraining area to restrain the middle part, thereby improving the stability of the connection between the first chain and the middle part, and thus improving the lifting safety of the torsion block.

[0021] By adopting the above-mentioned technical scheme, the second chain is lifted through the setting of the rotating disk, the eccentric column and the pulling rod to drive the rotating shaft to rotate, so that the limit hook closes the inlet and outlet of the movable groove. During the rotation of the rotating shaft, the rotating disk is driven to rotate synchronously, so that the eccentric column can revolve around the central axis of the rotating shaft. The eccentric column can pull the moving block through the pulling rod, thereby driving the moving block to move, so as to reduce the size of the restraining area, tighten the middle part, and improve the operational convenience of the overall structure.

The height gradually decreases from the side close to the entrance to the side far from the entrance; the two ends of the first chain 2 are respectively connected to the clamping plate 12 of the hanger 1 through the first connecting lock buckle 22 and the movable ring 23, and the first chain 2 and the corresponding clamping plate 12 are combined to form a restraining area 21 for restraining the middle part 71. The hanger 1 connects the two ends of the middle part 71 through two first chains 2. When one end of the middle part 71 is inserted into the restraining area 21, the bottom wall of the clamping plate 12 abuts against the arc surface 73 of the middle part 71.

The locking bolts 222 are sequentially penetrated through the through holes at both ends of the locking rod 221. The locking nut 223 is sleeved on the locking bolt 222 and is threadedly connected with the locking bolt 222.

[0039] Reference Figure 3 , Figure 4 The plate surfaces of the two clamping plates 12 that are away from each other are fixedly installed with hanging plates 14, and the plate surfaces of the hanging plates 14 are opened with hanging holes 144. The second lifting chain group is arranged at the top of the hanger 1 for connecting to the crane and other lifting equipment. The second lifting chain group includes two second chains 3. The two second chains 3 are arranged corresponding to the hanging plates 14 of the two clamping plates 12.

The second connecting lock is hung on the hanging hole 144 of the hanging plate 14. The second chain 3 is connected to the hanger 1 through the second connecting lock. The third connecting locks of the two second chains 3 are commonly hung with a hanging ring 31, and the hanging ring 31 is used to connect the crane.

[0040] In this embodiment, the lengths of the two second chains 3 are set to be different, and the specific lengths of the two second chains 3 are determined according to the inclination angle of the slope; the structures of the first connecting lock buckle 22, the second connecting lock buckle and the third connecting lock buckle are the same, and the structures of the second connecting lock buckle and the third connecting lock buckle are not repeated here. The specific reference to the structure of the first connecting lock buckle 22 can be obtained by the same logic.

[0041] The implementation principle of Example 1 of the present application is as follows: when lifting the twist king block 7, the hanger 1 is placed on the arc surface 73 of the middle part 71, and then the two ends of the middle part 71 are respectively connected and fixed by two first chains 2, and then the two second chains 3 are connected to the crane. The lengths of the two second chains 3 are set to be different, so that after the twist king block 7 is lifted, it can present a certain inclination angle to adapt to the inclination angle of the slope. The twist king block 7 is lifted to the designated position by the crane and lowered, without the need to manually fine-tune the falling angle of the twist king block 7 continuously, thereby improving the work efficiency of the placement of the twist king block 7.

[0042] After the torsion block 7 is tilted and lifted, the two ends of the limit rod 13 can respectively support the arc-shaped surfaces 73 of the two side portions 72, thereby limiting the torsion block 7 and reducing the possibility of slipping of the torsion block 7 during the lifting process; at the same time, the two reinforcement frames 17 can abut against the two side portions 72, thereby improving the stability of the connection between the torsion block 7 and the hanger 1.

[0043] After the twist block 7 falls and is placed at the designated position, the movable ring 23 is pulled to separate the movable ring 23 from the movable groove 122 through the inlet and outlet, so that one end of the first chain 2 can be opened, thereby improving the convenience of disassembly and assembly between the twist block 7 and the hanger 1.

[0044] Embodiment 2: The embodiment of the present application discloses a torsion block hanger.

[0045] Reference Figure 5 The difference between the torsion block hanger disclosed in the embodiment of the present application and the embodiment 1 is that: In this embodiment, a limit stop hook 4 is provided on the plate surface of each card plate 12, and the limit stop hook 4 is located on the plate surface of the card plate 12 away from the connecting rod 11. The limit stop hook 4 is provided with a rotating shaft 41, one end of the rotating shaft 41 is fixedly connected to the limit stop hook 4, and the other end is rotatably installed on the card plate 12, and the limit stop hook 4 is rotatably installed on the plate surface of the card plate 12 away from the connecting rod 11 through the rotating shaft 41; in this embodiment, the limit stop hook 4 is located on the side of the card plate 12 close to the movable groove 122, so as to open and close the inlet and outlet of the movable groove 122.

[0046] Reference Figure 5A linkage assembly 5 is provided between the second chain 3 and the limit stop hook 4. The limit stop hook 4 normally opens the inlet and outlet of the movable groove 122. When the second chain 3 is tightened to lift the hanging plate 14, the linkage assembly 5 drives the limit stop hook 4 to rotate and close the inlet and outlet of the movable groove 122; the linkage assembly 5 includes a linkage block 51 and a linkage rod 52. The hanging plate 14 is provided with a sliding groove 141. The sliding groove 141 has a first point position 142 and a second point position 143. The first point position 142 is located below the second point position 143. The linkage block 51 is slidably installed in the sliding groove 141.

[0047] Reference Figure 5 One end of the linkage rod 52 is hinged to the linkage block 51, and the other end is hinged to the limit hook 4. When the linkage block 51 is located at the first point 142, the limit hook 4 opens the entrance and exit of the movable groove 122. When the second chain 3 is tightened to lift the hanging plate 14, the second chain 3 drives the linkage block 51 to move up to the second point 143. The limit hook 4 rotates under the pull of the linkage rod 52 to close the entrance and exit of the movable groove 122.

[0048] The hanging plate 14 is provided with an anti-slip block 145 at the second point 143 of the sliding groove 141. The anti-slip block 145 is used to limit the linkage block 51 in the sliding groove 141. When the linkage block 51 moves up to the second point 143, the linkage block 51 abuts against the anti-slip block 145. It should be noted that, in the present embodiment, the linkage block 51 slides down to the first point 142 of the sliding groove 141 by its own gravity. In other embodiments, a spring may be added between the linkage block 51 and the sliding groove 141 to ensure that the linkage block 51 is normally in the first point 142 of the sliding groove 141 (i.e., the limit hook 4 normally opens the inlet and outlet of the movable groove 122).

[0049] The implementation principle of Example 2 of the present application is: after the movable ring 23 of the first chain 2 is hung on the movable groove 122 of the clamping plate 12, the torsion block 7 is lifted. When the crane drives the hanger 1 to move up through the second chain 3, the second chain 3 pulls the linkage block 51, forcing the linkage block 51 to move up to the second point 143. At this time, the linkage rod 52 pulls the limit stop hook 4, forcing the limit stop hook 4 to close at the inlet and outlet of the movable groove 122 to block the movable ring 23, thereby reducing the possibility of the movable ring 23 detaching from the movable groove 122 during the lifting process of the torsion block 7, thereby improving the stability of the connection between the clamping plate 12 and the first chain 2, and thereby improving operation safety.

[0050] Embodiment 3: The embodiment of the present application discloses a torsion block hanger.

[0051] Reference Figure 6The difference between the torsion block hanger disclosed in the embodiment of the present application and the embodiment 2 is that: A movable groove 123 is provided on the plate surface of the card plate 12, and both ends of the movable groove 123 are extended in the horizontal direction (that is, the two ends of the movable groove 123 are extended along the length direction of the card plate 12), and a movable block 15 is slidably installed in the movable groove 123. In this embodiment, the connecting groove 121 is provided in the movable block 15; a tensioning assembly 6 is provided between the movable block 15 and the limit stop hook 4, and when the limit stop hook 4 closes the inlet and outlet of the movable groove 122, the tensioning assembly 6 drives the movable block 15 to move toward the side close to the movable groove 122.

[0052] Reference Figure 6 , Figure 7 The tensioning assembly 6 includes a rotating disk 61, an eccentric column 62 and a pulling rod 63. One end of the rotating shaft 41 passes through the side of the card plate 12 close to the connecting rod 11 and is coaxially connected to the rotating disk 61. The rotating disk 61 is rotatably installed on the card plate 12 through the rotating shaft 41; one end of the eccentric column 62 is installed on the surface of the rotating disk 61 away from the card plate 12, and the eccentric column 62 is eccentrically arranged between the rotating disk 61 (that is, the central axis of the eccentric column 62 is parallel to the central axis of the rotating disk 61, and the eccentric column 62 can revolve around the rotating shaft 41).

[0053] Reference Figure 7 , one end of the pulling rod 63 is hinged to the eccentric column 62, and the other end is hinged to the moving block 15. In this embodiment, the pulling rod 63 includes a first pulling part 631, a second pulling part 632 and a connecting part 633. The first pulling part 631 and the second pulling part 632 are coaxially arranged, one end of the first pulling part 631 away from the second pulling part 632 is hinged to the eccentric column 62, and one end of the second pulling part 632 away from the first pulling part 631 is hinged to the moving block 15; the connecting part 633 is sleeved between the first pulling part 631 and the second pulling part 632. In this embodiment, the connecting part 633 and the first pulling part 631, and the connecting part 633 and the second pulling part 632 are all threadedly connected (the thread is not shown in the figure), and the thread rotation directions of the connecting part 633 and the first pulling part 631, and the connecting part 633 and the second pulling part 632 are opposite.

[0054] The implementation principle of Example 3 of the present application is as follows: one end of the first chain 2 is hooked on the connecting groove 121 of the movable block 15, and the other end is hooked on the movable groove 122. When the crane lifts the second chain 3, the second chain 3 pulls the limit stop hook 4 through the linkage block 51, forcing the limit stop hook 4 to close the inlet and outlet of the movable groove 122; in the process of the limit stop hook 4 rotating to close the movable groove 122, the rotating shaft 41 drives the rotating disk 61 to rotate, so as to pull the movable block 15, forcing the movable block 15 to move toward the side close to the movable groove 122, thereby reducing the size of the restraining area 21, that is, forcing the first chain 2 to be tightened to the middle part 71, greatly improving the connection stability between the first chain 2 and the middle part 71; reducing the possibility of slippage between the first chain 2 and the middle part 71.

[0055] When the first chain 2 is wrapped around the middle part 71, the connecting part 633 can be rotated in advance to force the first pulling part 631 and the second pulling part 632 to move closer to or away from each other to adjust the length of the pulling rod 63, thereby adjusting the initial position of the moving block 15, and then one end of the first chain 2 is wrapped around the middle part 71 and hung on the movable groove 122 to adapt to the restraint of the middle parts 71 of different sizes and improve the adaptability of the overall structure.

[0056] Embodiment 4: The embodiment of the present application also discloses a method for hoisting a torsion block.
