Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and in particular to a construction engineering hoisting equipment and a hoisting method thereof. Background Art

[0002] In construction projects, marine lifting equipment can be used as a useful equipment for cargo handling on board ships. It has powerful lifting and recovery capabilities and can be used to handle heavy cargo and equipment that need to be lifted or moved in the handling project. In the case of limited waters near the construction site, ships can be used to load cargo or equipment and use winches for sea transportation. At the same time, when the construction site is located near the water, marine winches can provide additional handling and loading and unloading support, making it convenient to unload building materials and other goods from the ship to the shore.

[0003] Because the hull cannot maintain stability on land when used on a ship, the hoisting equipment as a whole is in a state of shaking, and most of the hoisting devices in the prior art are directly suspended by cables. Combined with the use environment on water, the hoisted cargo is very unstable and has great safety hazards. Therefore, those skilled in the art provide a construction engineering hoisting device and a hoisting method thereof to solve the problems raised in the above background technology.

[0012] Preferably, the upper and lower ends of the telescopic tube are provided with guide rails, and the inner walls of the upper and lower ends of the tube seat are rotatably mounted with balls that are equidistantly distributed and rollingly mounted inside the guide rails. When the telescopic tube slides inside the tube seat, the balls slide inside the guide rails to provide sliding support, thereby avoiding direct friction between the telescopic tube and the inner wall of the tube seat, reducing wear when the telescopic tube moves, and adjusting the rolling support so that the telescopic tube moves smoothly and stably.

[0015] A construction engineering hoisting method, the hoisting method steps are as follows:

[0016] S1: The lifting structure on the ship is hooked by the lifting hook. After hooking, the cargo is transported by the lifting structure.

[0017] S2: The hook structure in the stabilizing structure is connected by a stabilizing cable, which is retracted and released by a winding roller. When an upward pulling force is applied to the upper end of the cargo, the stabilizing cable is released, and the lifting cable and the stabilizing cable are retracted and released in a corresponding manner, so as to keep the stabilizing cable taut, thereby pulling the bottom of the hoisted cargo;

[0018] S3: In the stable structure, the extension motor drives the screw to rotate and cooperates with the nut to adjust the position of the telescopic tube. During the adjustment process, the stable cable is retracted and released, and the retraction and extension are adjusted accordingly with the extension and storage of the telescopic tube. At the same time, the angle of the sleeve is adjusted through the rotating shaft, thereby adjusting the angle of the stable hook, so that the cargo at different positions can be effectively hung at the bottom.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention uses a lifting structure on board to lift the cargo, thereby facilitating the transportation of cargo at construction sites near water areas or at sea. At the same time, when transporting the cargo, the bottom of the cargo is connected by two stabilizing cables. During the continuous lifting of the cargo, the stabilizing cables are correspondingly unwound. Since the bottom of the cargo is supported, the cargo is prevented from shaking greatly due to the instability of the ship. The stability of the cargo when hoisted on board is improved, the risk of cargo falling is reduced, and the safety of hoisting is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 9 , four embodiments provided by the present invention are:

[0036] Embodiment 1:

[0037] A construction engineering hoisting device, comprising a hoisting structure 100, an angle adjustment structure 200, a stabilizing structure 300 and a clamping structure 400, wherein the hoisting structure 100 comprises a hoisting arm 101, a telescopic arm 104 slidably mounted with the hoisting arm 101, a hoisting pulley 102 located at the upper ends of the hoisting arm 101 and the telescopic arm 104, a hoisting cable 103 slidably mounted inside the hoisting pulley 102, and a hoisting hook 105 located at the lower end of the hoisting cable 103;

[0038] In this embodiment: the lifting arm 101 and the telescopic arm 104 are the extension arms of the lifting equipment, and the lifting arm 101 and the lifting hook 105 use the hydraulic cylinder as the power source to unfold the lifting arm 101 and the telescopic arm 104, and adjust the length of the telescopic arm 104 as needed. The lifting cable 103 is slidably supported by the conveying pulley 306, and the cargo is fixed with the lifting cable 103 and connected to the lifting hook 105 for lifting. The conveying pulley 306 is used to lift the cargo or equipment off the ground and ensure a safe distance. The lifting and moving process of the cargo is controlled by correctly operating the lifting cable 103, and the cooperative operator lifts the cargo through the lifting hook 105.

[0039] Embodiment 2:

[0040] The stabilizing structure 300 includes relatively distributed pipe seats 301, a telescopic pipe 303 slidably mounted inside the pipe seat 301, a winding motor 310 located at one side of the pipe seat 301, a reel 309 located at the output end of the winding motor 310, a stabilizing cable 304 wound on the outer wall of the reel 309, a stabilizing hook 311 located at one end of the stabilizing cable 304, an extension motor 316 fixed inside the pipe seat 301, a screw rod 313 located inside the telescopic pipe 303 is provided at the output end of the extension motor 316, and a nut 314 threadedly mounted with the screw rod 313 and fixed inside the telescopic pipe 303;

[0041] A conveying pulley 306 is provided at the lower end of the pipe seat 301, and multiple groups of limiting pulleys 302 whose horizontal height is lower than the conveying pulley 306 are provided at the lower end of the pipe seat 301. Two groups of symmetrically distributed guide pulleys 305 are provided at one end of the telescopic tube 303, and a stabilizing cable 304 is slidably installed inside the conveying pulley 306, the limiting pulley 302 and the guide pulley 305;

[0042] A symmetrically distributed bearing bracket 307 is provided at the lower end of the adjustment seat 204, and the rotating shaft 205 is rotatably installed inside the bearing bracket 307;

[0043] The outer wall of the rotating shaft 205 is sleeved with symmetrically distributed limiting wheels 308, and the stabilizing cable 304 is located between the limiting wheels 308;

[0044] The upper and lower ends of the telescopic tube 303 are provided with guide rails 312, and the inner walls of the upper and lower ends of the tube seat 301 are rotatably installed with balls 315 that are equidistantly distributed and rollingly installed inside the guide rails 312;

[0045] The angle adjustment structure 200 includes a mounting seat 203, and a pitch adjustment motor 202 is disposed at the lower and upper ends of the mounting seat 203. The output end of the pitch adjustment motor 202 is provided with a rotating shaft 205 rotatably mounted inside the mounting seat 203;

[0046] The outer wall of the rotating shaft 205 is sleeved with an adjusting seat 204 fixedly connected to the pipe seat 301, and a mounting plate 201 is arranged at the lower end of the mounting seat 203, and a mounting hole is opened inside the mounting plate 201;

[0047] In this embodiment, during the cargo hoisting process, after the cargo is lifted to a position of about 1.5 meters above the ground by the hoisting hook 105, the extension motor 316 operates to drive the screw rod 313 to rotate. Since the telescopic tube 303 is guided by sliding inside the tube seat 301, the screw rod 313 rotates in the thread rolling inside the nut 314, and then the telescopic tube 303 is adjusted in position according to the rotation direction of the screw rod 313, or extended out of the tube seat 301, or stored in the tube seat 301. In this process, , because the stabilizing hook 311 is located inside the guide pulley 305, it will exert a pulling force on the stabilizing cable 304. At this time, the winding motor 310 operates to drive the winding roller 309 to rotate, and the stabilizing cable 304 is released. The stabilizing cable 304 moves with the telescopic tube 303. At the same time, the pitch adjustment motor 202 operates to drive the rotating shaft 205 to rotate, and the rotating shaft 205 drives the adjusting seat 204 to rotate. The rotation of the adjusting seat 204 drives the tube seat 301 to rotate, and then the angle of the stabilizing hook 311 is adjusted;

[0048] The stabilizing hook 311 moves to the lower end of the cargo, and the two ends of the cargo are sleeved by the stabilizing hook 311. During the cargo lifting process, the stabilizing cable 304 is continuously released according to the movement of the cargo, and the stabilizing cable 304 is kept tensioned to hold the two sides of the lower end of the cargo. The cargo is lifted on the water surface, especially when the lifting structure 100 is also on the ship. The overall structure will shake unpredictably with the water surface conditions, which will lead to unstable cargo lifting. At this time, the two sides of the lower end of the cargo are held, the stability of the cargo lifting is improved, and then, the safety hazards during cargo lifting are reduced.

[0049] Embodiment three:

[0050] The clamping structure 400 includes a U-shaped seat 401 sleeved on the outer wall of the stabilizing cable 304, and a receiving groove 406 is formed on the inner wall of the lower end of the U-shaped seat 401, and the stabilizing hook 311 is located inside the receiving groove 406;

[0051] Screw holes 407 are provided at both ends of the U-shaped seat 401, and screw rods 405 are threadedly installed inside the screw holes 407. The outer wall of the screw rods 402 is provided with a circular array distribution. A clamping plate 403 is provided on one side of the screw rods 405. A bearing seat 404 is provided at one end of the clamping plate 403. One end of the screw rods 405 is rotatably inserted into the bearing seat 404.

[0052] In this embodiment: due to different packaging, some goods cannot be connected with the stabilizing hook 311 at the bottom. At this time, the grasping rotary rod 402 drives the second screw 405 to rotate, and the second screw 405 drives the clamping plate 403 to move relatively. At this time, the stabilizing hook 311 is stored in the storage groove 406 and will not cause any obstruction to the clamping plate 403. The clamping plate 403 clamps the outer wall of the packaging frame of the goods, thereby realizing the connection between the stabilizing cable 304 and the hoisted goods, providing additional fixed adjustment for the stable binding of the goods during the hoisting process, and improving the flexibility of use.

[0055] S1: The lifting structure 100 on the ship is connected by the lifting hook 105. After connection, the cargo is transported by the lifting structure 100. The cargo is transported by the lifting cable 103 that is rolled up and moved by the lifting structure 100. Before the cargo is lifted, the bottom of the cargo is connected by the stabilizing hook 311.

[0056] S2: The hook structure in the stabilizing structure 300 is connected by a stabilizing cable 304, and the cable is retracted and released by a reel 309. When an upward pulling force is applied to the upper end of the cargo, the stabilizing cable 304 is released, and the lifting cable 103 corresponds to the retraction and extension of the stabilizing cable 304, so as to keep the stabilizing cable 304 taut, thereby pulling the bottom of the hoisted cargo;

[0057] S3: In the stabilizing structure 300, the extension motor 316 drives the screw rod 313 to rotate and cooperates with the nut 314 to adjust the position of the telescopic tube 303. During the adjustment process, the stabilizing cable 304 is retracted and extended, and the extension and extension are adjusted accordingly with the extension and storage of the telescopic tube 303. At the same time, the angle of the sleeve is adjusted through the rotating shaft 205, and then the angle of the stabilizing hook 311 is adjusted, so that the cargo at different positions can be effectively hung at the bottom.
