Description

Technical Field

[0001] The present application relates to the field of hoisting structures, and in particular to a hoisting structure for a prefabricated cabin. Background Art

[0002] The lifting structure of a prefabricated cabin refers to the support and connection system used to install and lift the prefabricated cabin. These structures are usually made of steel or other metal materials to ensure sufficient strength and stability to support and operate the cabin.

[0003] At present, the Chinese patent with the existing patent publication number CN207684713U discloses a hoisting structure for a prefabricated cabin body, which comprises two symmetrically arranged cross bars, each cross bar being slightly longer than the width of the prefabricated cabin roof, and two ends of the cross bars (1) are respectively fixed with positioning belts (6), the positioning belts (6) being arranged in a V-shape, the lower end of the positioning belts (6) being fixed with a lifting ring (4) that can be docked with a hoisting seat (3), the two cross bars being connected and fixed into one body by two lifting belts (5), and the middle part of the positioning belts (6) can be hung on the hook of the hoisting equipment. The utility model has a simple structure and a relatively simple docking method, and is convenient for rapid hoisting outdoors. During the hoisting process, the positioning belts will not contact and crush the roof of the prefabricated cabin, and the overall hoisting is more stable, which is conducive to promotion.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that when installing the prefabricated cabin on the lifting structure, cabins of different specifications cannot be fixed, which is inconvenient to use and reduces the diversity of the lifting structure. When lifting the prefabricated cabin, the entire lifting structure is lifted by a crane. When the cabin is placed at a designated location, the lifting structure will be subject to pressure from the ground. The lifting structure may be damaged if it is under the action of force for a long time, thereby reducing the service life of the structure. Utility Model Content

[0005] The hoisting structure of a prefabricated cabin provided in the present application can fix the cabin on the hoisting structure when facing cabins of different specifications, which is convenient to use and improves the diversity of the structure. When the hoisting structure lowers the cabin, it has a buffering effect to protect the structure and increase the service life of the structure.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a hoisting structure of a prefabricated cabin, the hoisting structure comprising:

[0007] base;

[0008] A support rod is fixedly arranged on one side of the base, and a bidirectional motor is installed on one side of the support rod;

[0009] The bidirectional screw is fixedly arranged on the output shaft of the bidirectional motor, and the outer surface of the bidirectional screw is threadedly sleeved with two threaded barrels;

[0010] The long rod is fixedly arranged on both sides of the inner wall of the base, and two slide cylinders are movably sleeved on the outer surface of the long rod;

[0011] Two connecting plates are fixedly provided on one side of the two threaded barrels, and two first supporting plates are fixedly provided on one side of the two connecting plates;

[0012] A plurality of second support plates are movably sleeved on the outer sides of the plurality of first support plates, and a pressure plate is fixedly provided on one side of each of the plurality of second support plates;

[0013] A plurality of limiting rods are movably embedded in one side of the plurality of second support plates, and the plurality of limiting rods are evenly divided into two groups, and a cover plate is fixedly provided on one side of the limiting rods of the two groups;

[0014] The two handles are respectively fixed on the opposite sides of the two cover plates.

[0015] As a further improvement of the present application: both sides of the bidirectional screw are arranged on both sides of the inner wall of the base through bearings, and one side of the two connecting plates is respectively connected to one side of the two slide cylinders.

[0016] As a further improvement of the present application: a protective mechanism is provided on one side of each of the plurality of second support plates, the protective mechanism comprising a frame, and vertical poles are fixedly provided on both sides of the inner wall of the frame.

[0017] As a further improvement of the present application: two sleeves are movably provided on the outer surface of the vertical pole, and springs are fixedly provided on opposite sides of the two sleeves.

[0018] As a further improvement of the present application: the two springs are movably sleeved on the outer surface of the vertical pole respectively, and a first horizontal axis is fixedly provided on one side of the two sleeves.

[0019] As a further improvement of the present application: a transmission rod is movably sleeved on the outer surfaces of the two first transverse shafts, and a second transverse shaft is movably embedded on one side of the two transmission rods.

[0020] As a further improvement of the present application: a convex plate is fixedly provided on one side of the two second transverse axes, and a bottom plate is fixedly provided on one side of the convex plate.

[0021] As a further improvement of the present application: a connecting hook is fixedly provided on one side of the base, and a positioning hole matching one of the limiting rods is opened on one side of each of the plurality of second support plates.

[0022] Compared with the prior art, the advantages and positive effects of this application are:

[0023] 1. In the present application, when the prefabricated cabin needs to be lifted, the lifting structure is hung inside the lifting hook on the crane through the connecting hook. At this time, the bidirectional motor is controlled to rotate in the forward direction, so that the two threaded cylinders move in opposite directions, thereby moving the multiple pressure plates to both sides. At this time, the multiple limit rods are removed from the multiple second support plates through the two handles. The multiple second support plates can slide outside the multiple first support plates respectively. By sliding the multiple second support plates, the distance between the base and the multiple pressure plates is controlled. This distance is the height of the cabin. Then, through the two pressure plates, the multiple limit rods are inserted into the positioning holes on the multiple second support plates to fix the positions of the multiple second support plates. At this time, the lifting structure is moved to the side of the cabin by the crane. The crane uses the connecting hook to position the cabin below the base. At this time, one side of the multiple pressure plates is on the ground. The bidirectional motor is controlled to rotate in the reverse direction so that the multiple pressure plates are inserted into the bottom position of the cabin. At this time, the cabin can be lifted to the designated location. Therefore, through the movable multiple pressure plates, when facing cabins of different specifications, the cabin can be fixed on the lifting structure, which is convenient to use and improves the diversity of the structure.

[0024] 2. In the present application, after the cabin is moved to the designated location, when the crane lowers the cabin, one side of the bottom plate in the multiple protective mechanisms will first contact the ground. At this time, the bottom plate is subjected to pressure from the ground, which is transmitted to the two transmission rods through the convex plate. The two transmission rods can rotate around the two first transverse axes or the two second transverse axes, and the two sleeves can slide on the outer surface of the vertical pole, so that the two sleeves are pushed by the two transmission rods, so that the two sleeves squeeze the two springs respectively. When the two springs are squeezed, a reverse force will be generated, which can offset a part of the force applied to the bottom plate, so that the entire lifting structure has a buffering effect when lowering the cabin, thereby protecting the structure and increasing the service life of the structure.

Therefore, the present application is not limited to the specific embodiments disclosed in the following specification.

[0033] Example 1, as Figure 1-5 As shown, the present application provides a hoisting structure for a prefabricated cabin, the hoisting structure comprising:

[0034] Base 1;

[0035] A support rod 201 is fixedly mounted on one side of the base 1, and a bidirectional motor 202 is mounted on one side of the support rod 201.

[0036] The bidirectional screw rod 203 is fixedly mounted on the output shaft of the bidirectional motor 202. The outer surface of the bidirectional screw rod 203 is threaded with two thread barrels 204. The outer surface of the bidirectional screw rod 203 has two threads with different rotation directions.

[0038] Two connecting plates 207 are fixedly disposed on one side of the two threaded cylinders 204, and two first support plates 208 are fixedly disposed on one side of the two connecting plates 207. The movement of the two connecting plates 207 drives the movement of the multiple first support plates 208.

[0039] Multiple second support plates 209 are movably mounted on the outside of the multiple first support plates 208, and a pressure plate 213 is fixedly provided on one side of the multiple second support plates 209. The multiple second support plates 209 can slide on the outside of the multiple first support plates 208, and the multiple pressure plates 213 can be inserted into the bottom of the cabin;

[0040] A plurality of limiting rods 212 are movably embedded in one side of the plurality of second support plates 209, and the plurality of limiting rods 212 are evenly divided into two groups. A cover plate 210 is fixedly provided on one side of each of the two groups of limiting rods 212. The plurality of limiting rods 212 respectively limit the plurality of second support plates 209, and the plurality of limiting rods 212 are connected together by the two cover plates 210.

[0041] The two handles 211 are fixedly disposed on opposite sides of the two cover plates 210 , and the two limiting rods 212 facilitate removal or insertion of the two cover plates 210 .

[0042] like Figure 1-5 As shown, both sides of the bidirectional screw rod 203 are arranged on both sides of the inner wall of the base 1 through bearings, and one side of the two connecting plates 207 is connected to one side of the two slide cylinders 206 respectively. The bidirectional screw rod 203 can rotate because of the bearings.

[0043] like Figure 1-5 As shown, a protective mechanism 3 is provided on one side of each of the plurality of second support plates 209 . The protective mechanism 3 includes a frame 301 . Vertical poles 302 are fixedly provided on both sides of the inner wall of the frame 301 . The protective mechanism 3 has a protective function for the hoisting structure.

[0044] like Figure 1-5 As shown, two sleeves 303 are movably sleeved on the outer surface of the vertical rod 302 , and springs 304 are fixedly provided on opposite sides of the two sleeves 303 , so that the two sleeves 303 can slide on the outer surface of the vertical rod 302 .

[0045] like Figure 1-5 As shown, two springs 304 are movably sleeved on the outer surface of the vertical rod 302, and a first horizontal axis 305 is fixedly provided on one side of the two sleeves 303. The two springs 304 will generate a reverse force when squeezed.

[0046] like Figure 1-5As shown, the outer surfaces of the two first transverse shafts 305 are movably sleeved with transmission rods 306, and one side of the two transmission rods 306 is movably embedded with a second transverse shaft 307. The two transmission rods 306 can rotate around the two first transverse shafts 305 or the two second transverse shafts 307 as axes.

[0047] like Figure 1-5 As shown, a convex plate 308 is fixedly provided on one side of the two second transverse axes 307 , and a bottom plate 309 is fixedly provided on one side of the convex plate 308 , and the bottom plate 309 is a force point.

[0048] like Figure 1-5 As shown, a connecting hook 2 is fixedly provided on one side of the base 1, and a positioning hole matching one of the limiting rods 212 is opened on one side of the multiple second support plates 209. The connecting hook 2 allows the lifting structure to be hung on the crane, and multiple limiting rods 212 can be inserted through the multiple positioning holes.

[0049] Working principle: When the prefabricated cabin needs to be lifted, the lifting structure is hung inside the hook on the crane through the connecting hook 2. At this time, the external power supply of the bidirectional motor 202 is turned on, and the output shaft of the bidirectional motor 202 can rotate forward and reverse. The two threaded barrels 204 are respectively connected to the two threaded lines of different rotation directions on the outer surface of the bidirectional screw rod 203, and the two threaded barrels 204 are respectively connected to the slide barrel 206 through two connecting plates 207. The two slide barrels 206 can slide on the outer surface of the long rod 205, so that when the bidirectional screw rod 203 rotates in different directions, the two threaded barrels 204 move in opposite directions on the outer surface of the bidirectional screw rod 203. At this time, the bidirectional motor is controlled 202 rotates forward, causing the two threaded cylinders 204 to move in opposite directions, thereby causing the multiple pressure plates 213 to move to both sides. At this time, the multiple limiting rods 212 are removed from the multiple second support plates 209 through the two handles 211, and the multiple second support plates 209 can slide on the outside of the multiple first support plates 208 respectively. By sliding the multiple second support plates 209, the distance between the base 1 and the multiple pressure plates 213 is controlled. This distance is the height of the cabin, and then the multiple limiting rods 212 are inserted into the positioning holes on the multiple second support plates 209 through the two pressure plates 213 to fix the positions of the multiple second support plates 209. At this time, The crane moves the hoisting structure to the side of the cabin, and the crane makes the cabin be located below the base 1 through the connecting hook 2. At this time, one side of the multiple pressure plates 213 is on the ground, and the bidirectional motor 202 is controlled to rotate in the opposite direction so that the multiple pressure plates 213 are inserted into the bottom position of the cabin. At this time, the cabin can be hoisted to the designated location, so that the cabin can be fixed on the hoisting structure when facing cabins of different specifications through the movable multiple pressure plates 213, which is convenient to use and improves the diversity of the structure. After the cabin is moved to the designated location, when the crane lowers the cabin, one side of the bottom plate 309 in the multiple protection mechanisms 3 will first touch the ground. At this time, the bottom plate 309 is subjected to the pressure of the ground, which is transmitted to the two transmission rods 306 through the convex plate 308. The two transmission rods 306 can rotate around the two first horizontal axes 305 or the two second horizontal axes 307, and the two sleeves 303 can slide on the outer surface of the vertical rod 302. As a result, the two sleeves 303 are pushed by the two transmission rods 306, so that the two sleeves 303 squeeze the two springs 304 respectively. When the two springs 304 are squeezed, a reverse force will be generated, which can offset part of the force applied to the bottom plate 309, so that the entire lifting structure has a buffering effect when lowering the cabin, thereby protecting the structure and increasing the service life of the structure.
