It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

As shown, the lifting device includes: a main body 1, a hook 2, at least one lifting lug 3, at least one lifting device 4, and at least one support mechanism 5. The main body 1 is elongated and has a preset length, which can be determined according to actual conditions; this embodiment does not impose any restrictions on this. In specific implementation, the main body 1 can be an H-beam or other structures; this embodiment does not impose any restrictions on this.

[0022] Preferably, the interior of the main body 1 is hollow, and multiple reinforcing plates 8 are spaced apart inside the main body 1. Specifically, reinforcing plates 8 are provided inside the middle part of the main body 1, and also inside the two ends of the main body 1. By providing multiple reinforcing plates 8, the structural strength of the main body 1 is improved, thereby ensuring the strength and stability of the hoisting device.

[0023] Hook 2 is set on the top surface of the main body 1. Figure 1 In the center of the above (as shown), preferably, the hook 2 and the top surface of the main body 1 are welded together.

[0024] The bottom surface of main body 1 ( Figure 1 As shown below, both ends of the main body 1 are equipped with guy lugs 9. Specifically, two guy lugs 9 are respectively located at the two ends of the bottom surface of the main body 1. Each guy lug 9 is fixedly connected to the main body 1 and is used to connect with the guy rope. In this way, the rotation direction of the hoisted object can be controlled manually during hoisting, and collisions with other structures can be prevented.

[0025] Each lifting lug 3 is located on the bottom surface of the main body 1, and the lifting lugs 3 are spaced apart on the bottom surface of the main body 1. Preferably, the lifting lugs 3 are evenly distributed. The number of lifting devices 4 is the same as the number of lifting lugs 3. Each lifting device 4 corresponds one-to-one with each lifting lug 3. The first end of each lifting device 4 is connected to the corresponding lifting lug 3 through a first steel wire rope, and the second end of each lifting device 4 is connected to the object being lifted through a second steel wire rope.

[0026] Each support mechanism 5 is spaced apart on the bottom surface of the main body 1. Specifically, the position of each support mechanism 5 on the bottom surface of the main body 1 can be determined according to the actual situation. More specifically, each support mechanism 5 is placed between two adjacent lifting lugs 3. Furthermore, the height of each support mechanism 5 is adjustable, allowing the height of each support mechanism 5 to be adjusted according to the ground conditions, thereby providing stable support for the main body 1 and preventing the main body 1 from tipping over.

[0027] In practice, the number of lifting lugs 3 and the number of supporting mechanisms 5 can be determined according to the actual situation, and this embodiment does not impose any restrictions on this. In this embodiment, there are four lifting lugs 3, four lifting devices 4, and two supporting mechanisms 5.

[0028] It can be seen that in the embodiment, the lifting lugs 3 are arranged at intervals on the bottom surface of the main body 1, the first end of each lifting appliance 4 is connected to the corresponding lifting lug 3 through the first steel wire, and the second end of each lifting appliance 4 is connected to the hoisted object through the second steel wire. In this way, the stability of hoisting between the main body 1 and the hoisted object can be ensured, and the hoisted object can be normally lifted. In addition, the bottom surface of the main body 1 is in contact with the ground through the support mechanisms 5, the support mechanisms 5 support the main body 1, preventing the main body 1 from being damaged by direct contact with the ground. The height of each support mechanism 5 can be adjusted, and the height of the support mechanism 5 can be adjusted according to the state of the ground. Even if the ground is uneven, the height of the corresponding support mechanism 5 can be adjusted according to the uneven state of the ground, so that the hoisting device can be stably placed on the ground, preventing the hoisting device from toppling over. The problem of poor stability of the hoisting device placed on uneven ground in the prior art is solved.

The clamp 41 is S-shaped, and the middle part of the blocking piece 42 is rotatably connected to the middle part of the clamp 41, so that the blocking piece 42 can rotate relative to the middle part of the clamp 41.

In this way, two hoisting spaces 7 are formed between the blocking piece 42 and the clamp 41, one of which is used to accommodate the first steel wire, and the other of which is used to accommodate the second steel wire.

[0030] The clamp 41 comprises an inclined section 411, two arc-shaped sections 412, a first straight section 413 and a second straight section 414. The inclined section 411 is arranged obliquely, not vertically. The two ends of the inclined section 411 correspond to the two arc-shaped sections 412, each end of the inclined section 411 is connected to the first end of the corresponding arc-shaped section 412, and the second ends of the two arc-shaped sections 412 are connected to the first ends of the first straight section 413 and the second straight section 414, respectively.

The first straight section 413 and the second straight section 414 are also respectively arranged on two sides of the inclined section 411, and the second end of the first straight section 413 and the second end of the second straight section 414 are both free ends, and the second end of the first straight section 413 and the second end of the second straight section 414 are both extended to the inclined section 411, more specifically, the second end of the first straight section 413 is extended to the first end of the arc-shaped section 412 at the second straight section 414, and the second end of the second straight section 414 is extended to the first end of the arc-shaped section 412 at the first straight section 413. In this way, the inclined section 411, the two arc-shaped sections 412, the first straight section 413 and the second straight section 414 form an S shape.

[0032] In a specific implementation, the position of the second end of the first straight section 413 corresponds to the position of the second end of the second straight section 414.

[0033] Preferably, the clamp 41 is integrally formed.

[0034] The blocking piece 42 comprises a first blocking piece 421, a second blocking piece 422 and a connecting body 423. The middle part of the inclined section 411 is provided with a fixed shaft 6, the fixed shaft 6 is arranged in the middle part of the inclined section 411, and the two ends of the fixed shaft 6 are extended to the two sides outside the inclined section 411. And the fixed shaft 6 is fixedly connected with the inclined section 411, so that the fixed shaft 6 is relatively fixed with the inclined section 411.

[0035] The first blocking piece 421 and the second blocking piece 422 are both in U shape, specifically, the first blocking piece 421 has two parallel side walls and a connecting wall clamped between the first ends of the two side walls, the second ends of the two side walls form the open end of the first blocking piece 421, and the connecting wall forms the closed end of the first blocking piece 421. Correspondingly, the second blocking piece 422 also has an open end and a closed end.

[0036] The open end of the first block 421 is rotatably connected with the fixed shaft 6, and the open end of the second block 422 is also rotatably connected with the fixed shaft 6, and the closed end of the first block 421 and the closed end of the second block 422 are oppositely arranged. Specifically, the open end of the first block 421 and the open end of the second block 422 are both corresponding to the fixed shaft 6, and the first block 421 and the second block 422 are respectively arranged on both sides of the inclined section 411, so that the open end of the first block 421 and the open end of the second block 422 are oppositely arranged, the closed end of the first block 421 faces the inclined section 411, and the closed end of the second block 422 also faces the inclined section 411. The second ends of the two side walls of the first block 421 are rotatably connected with the two end portions of the fixed shaft 6 in a one-to-one correspondence, and the second ends of the two side walls of the second block 422 are also rotatably connected with the two end portions of the fixed shaft 6 in a one-to-one correspondence. Moreover, the second ends of the two side walls of the second block 422 are arranged inside the second ends of the two side walls of the first block 421, that is, the positions of the second ends of the two side walls of the second block 422 on the fixed shaft 6 are closer to the inclined section 411, and the second ends of the two side walls of the first block 421 are arranged on the outermost side of the fixed shaft 6. The size of the second block 422 is smaller than the size of the first block 421.

[0037] The two ends of the connecting body 423 are respectively connected with the first block 421 and the second block 422. Specifically, one end of the connecting body 423 is connected with one of the side walls of the first block 421, and the other end of the connecting body 423 is connected with the corresponding side wall of the second block 422, so that the first block 421 and the second block 422 are connected together through the connecting body 423. Moreover, the connecting body 423 is fixedly connected with the first block 421 and the second block 422.

[0038] Preferably, the connecting body 423 is two, and the two connecting bodies 423 are respectively arranged on both sides of the blocking piece 42. Specifically, the two side walls of the first block 421 are respectively denoted as a first side wall and a second side wall, and the two side walls of the second block 422 are also respectively denoted as a first side wall and a second side wall, and the position of the first side wall of the first block 421 corresponds to the position of the first side wall of the second block 422, and the position of the second side wall of the first block 421 corresponds to the position of the second side wall of the second block 422. One of the connecting bodies 423 is respectively connected with the first side wall of the first block 421 and the first side wall of the second block 422, and the other connecting body 423 is respectively connected with the second side wall of the first block 421 and the second side wall of the second block 422.

[0039] In specific implementation, the connecting body 423 can be semicircular or have other shapes, and the present embodiment does not make any limitation in this regard.

[0040] The second block 422 has a greater weight than the first block 421.

[0041] The second end of the first flat section 413 is inserted into the first block 421, and the inner side of the closed end of the first block 421 is fitted to the outer side of the second end of the first flat section 413. Specifically, the second end of the first flat section 413 is inside the first block 421, and the second end of the first flat section 413 corresponds to the inner side of the closed end of the first block 421. In order to ensure that the inner side of the closed end of the first block 421 is fitted to the outer side of the second end of the first flat section 413, the shape of the inner side of the closed end of the first block 421 matches the shape of the outer side of the second end of the first flat section 413.

[0042] Preferably, the outer side of the first end to the outer side of the second end of the first flat section 413 gradually inclines, and the thickness of the first end to the thickness of the second end of the first flat section 413 gradually decreases. Specifically, the inner side of the first end to the inner side of the second end of the first flat section 413 is in a vertical state, and because the thickness of the first end to the thickness of the second end of the first flat section 413 gradually decreases, the outer side of the first end to the outer side of the second end of the first flat section 413 gradually inclines inward. Correspondingly, the inner side of the closed end of the first block 421 is also in an inclined state, and the inclination amplitude and inclination state of the inner side of the closed end of the first block 421 match the inclination amplitude and inclination state of the outer side of the second end of the first flat section 413, so as to ensure that the inner side of the closed end of the first block 421 is fitted to the outer side of the second end of the first flat section 413.

[0043] The second end of the second flat section 414 is inserted into the second block 422, and the inner side of the closed end of the second block 422 is fitted to the outer side of the second end of the second flat section 414. Specifically, the second end of the second flat section 414 is inside the second block 422, and the second end of the second flat section 414 corresponds to the inner side of the closed end of the second block 422. In order to ensure that the inner side of the closed end of the second block 422 is fitted to the outer side of the second end of the second flat section 414, the shape of the inner side of the closed end of the second block 422 matches the shape of the outer side of the second end of the second flat section 414.

[0044] Preferably, the outer side of the first end of the second flat section 414 to the outer side of the second end is gradually inclined, and the thickness of the first end of the second flat section 414 to the thickness of the second end is gradually reduced. Specifically, the inner side of the first end of the second flat section 414 to the inner side of the second end is in a vertical state, and due to the thickness of the first end of the second flat section 414 to the thickness of the second end being gradually reduced, the outer side of the first end of the second flat section 414 to the outer side of the second end is gradually inclined inward. Correspondingly, the inner side of the closed end of the second block 422 is also in an inclined state, and the inclination amplitude and inclination state of the inner side of the closed end of the second block 422 match the inclination amplitude and inclination state of the outer side of the second end of the second flat section 414, so as to ensure that the inner side of the closed end of the second block 422 matches the outer side of the second end of the second flat section 414.

[0045] In specific use, the first block 421 and the second block 422 are pushed to rotate around the fixed shaft 6, so that the first block 421 and the second block 422 no longer block the two ends of the clamp 41, and the first steel wire rope is sleeved on the arc-shaped section 412 corresponding to the first block 421, and the second steel wire rope is sleeved on the arc-shaped section 412 corresponding to the second block 422. The first block 421 and the second block 422 are loosened, and due to the weight of the second block 422 being greater than the weight of the first block 421, the second block 422 rotates downward under the gravity of the second block 422, driving the first block 421 to rotate upward, so that the first block 421 and the second block 422 block the two ends of the clamp 41, and then the first steel wire rope and the second steel wire rope are respectively arranged in the two hoisting spaces 7 formed by the clamp 41 and the blocking piece 42, which can effectively prevent the steel wire rope from falling off the clamp 41. The first steel wire rope is connected with the lifting lug 3 through the lifting ring, and the second steel wire rope is connected with the hoisted object.

[0046] It can be seen that in the embodiment, the structure of each lifting appliance 4 is simple and easy to implement. By rotating the first block 421 and the second block 422 relative to the fixed shaft 6, the two ends of the clamp 41 are in an open state, which is convenient for the first steel wire rope and the second steel wire rope to be sleeved on the two arc-shaped sections 412. After sleeving, the first block 421 and the second block 422 are loosened, so that the two ends of the clamp 41 are in a closed state, and then the first steel wire rope and the second steel wire rope are stably arranged in the two hoisting spaces 7 formed by the clamp 41 and the blocking piece 42, which can effectively prevent the steel wire rope from falling off the clamp 41, ensure the stability between the steel wire rope and the clamp 41, and ensure that the hoisted object can be normally lifted. Moreover, the operation is simple and easy to implement.

[0047] Referring to Figure 1 and Figure 3In each of the above embodiments, each support mechanism 5 comprises a support column 51, a connecting plate 52, an adjusting bolt 53 and a support plate 54. The first end of the support column 51 is connected to the bottom surface of the main body 1, and the support column 51 is perpendicular to the bottom surface of the main body 1.

[0048] The connecting plate 52 is connected perpendicularly to the second end of the support column 51, and the connecting plate 52 is parallel to the bottom surface of the main body 1. The connecting plate 52 and the support column 51 form an inverted "T" shape structure.

[0049] The connecting plate 52 is provided with a threaded hole, and the adjusting bolt 53 is screwed into the threaded hole. The top of the adjusting bolt 53 faces the bottom surface of the main body 1. The bottom of the adjusting bolt 53 is provided with a support plate 54, and the support plate 54 is perpendicular to the adjusting bolt 53. The support plate 54 is used to contact the ground.

[0050] Preferably, the threaded hole is two, and the two threaded holes are respectively arranged on both sides of the support column 51.

[0051] The adjusting bolt 53 is two, and the two adjusting bolts 53 are screwed into the two threaded holes one by one. The top of the two adjusting bolts 53 faces the bottom surface of the main body 1.

[0052] The support plate 54 is two, and the two support plates 54 are respectively arranged one by one at the bottom of the two adjusting bolts 53 and contact the ground.

[0053] It can be seen that in the present embodiment, when the hoisting device is placed on the ground, since the ground cannot guarantee to be a flat surface, the adjusting bolt 53 is rotated to make the support plate 54 at the bottom of the adjusting bolt 53 contact the ground. The adjusting bolt 53 can be rotated according to the concave-convex degree of the ground, and the position of each adjusting bolt 53 on the connecting plate 52 is not uniform, thereby ensuring the stability of the main body 1 placed on the ground and preventing the phenomenon of tilting due to the unevenness of the ground.

[0054] Referring to Figures 1 to 3The use process of the hoisting device is introduced: when in use, the upper end of the first steel wire rope is connected with the lifting lug 3 through the existing lifting ring, the first block 421 and the second block 422 are pushed, the first block 421 and the second block 422 are rotated around the fixed shaft 6, the first block 421 and the second block 422 no longer block the two ends of the clamp 41, at this time, the lower end of the first steel wire rope is sleeved on the arc-shaped section 412 corresponding to the first block 421. The other arc-shaped section 412 is sleeved with the second steel wire rope, and the second steel wire rope is connected with the hoisted object. The pushing force on the first block 421 and the second block 422 is released, and due to the fact that the weight of the second block 422 is greater than that of the first block 421, under the action of the connecting body 423, the first block 421 and the second block 422 block the two ends of the clamp 41, so that the first steel wire rope and the second steel wire rope are stably sleeved on the two arc-shaped sections 412. At the same time, the cable wind rope is connected to the cable wind lug 9, and the portal crane is connected with the hook 2, and the hoisting operation of the hoisted object is carried out through the portal crane.

[0055] When the hoisting device is not used, the hoisting device is placed on the ground, according to the concave-convex degree of the ground, the adjusting bolt 53 is rotated, so that the supporting plate 54 at the bottom of the adjusting bolt 53 is in contact with the ground, thereby ensuring the stability of the hoisting device placed on the ground.

[0056] It can be seen that in the embodiment, the lifting lugs 3 are arranged at intervals on the bottom surface of the main body 1, the first end of each lifting device 4 is connected with the corresponding lifting lug 3 through the first steel wire rope, and the second end of each lifting device 4 is connected with the hoisted object through the second steel wire rope, so that the stability of hoisting between the main body 1 and the hoisted object can be ensured, and the hoisted object can be normally lifted. Moreover, the bottom surface of the main body 1 is in contact with the ground through the supporting mechanisms 5, the supporting mechanisms 5 support the main body 1, prevent the main body 1 from being damaged due to direct contact with the ground, and the height of each supporting mechanism 5 is adjustable, so that the height of the supporting mechanism 5 can be adjusted according to the state of the ground. Even if the ground is uneven, the height of the corresponding supporting mechanism 5 can be adjusted according to the concave-convex state of the ground, so that the hoisting device can be stably placed on the ground, and the hoisting device can be prevented from falling.
