Description

Technical Field

[0001] The present application relates to the technical field of wall lifting, and in particular to a lifting mechanism and a construction method thereof for realizing the installation of house walls based on BIM. Background Art

[0002] BIM stands for Building Information Model or Building Information Management. It uses various relevant information data of construction projects as the basis to establish a three-dimensional building model and simulate the real information of the building through digital information simulation.

[0003] The relevant Chinese patent with authorization announcement number CN213296868U discloses a BIM-based prefabricated building component, including a wall, fixed steel bars are embedded inside the wall, two lifting ear fixing tubes are pre-embedded inside the wall, and reinforcement holes are passed through the left and right sides of the two lifting ear fixing tubes. The tops of the two lifting ear fixing tubes are downwardly opened with threaded blind holes, and the internal threads of the threaded blind holes are connected to detachable lifting ears; during construction, the tower crane or crane's lifting device is combined with the two detachable lifting ears to lift the wall and move it to the designated installation position. After the wall is fixed to the floor, it can be unhooked. After unhooking, a practical crowbar is inserted into the lifting hole of the lifting ear body, and force can be applied to rotate the bolt to disengage the detachable lifting ear from the threaded blind hole on the lifting ear fixing tube to achieve the lifting of the wall.

[0004] Regarding the above-mentioned related technologies, the inventors found that when the wall is lifted to the designated floor by the above method, since the position of the lifting lugs is fixed, the wall is always in a vertical state. If the floor spacing is less than the height of the wall in the vertical state, the wall cannot be inserted into the floor in a vertical state, and the state of the wall cannot be adjusted at this time, resulting in inconvenience in wall installation. Summary of the Invention

[0005] In order to improve the technical problem of inconvenient wall installation existing in the related art, the present application provides a lifting mechanism and a construction method thereof for realizing house wall installation based on BIM.

[0006] In the first aspect, the present application provides a lifting mechanism for lifting house walls based on BIM, which adopts the following technical solutions:

[0007] A lifting mechanism for lifting a house wall based on BIM includes clamping plates symmetrically arranged at both ends of the wall, a clamping assembly for driving the clamping plates to clamp the wall, a lifting rope arranged on each clamping plate, an unwinding assembly for unwinding each lifting rope, and a crane, wherein one end of the lifting rope away from the clamping plate is connected to the unwinding assembly for unwinding the lifting rope through the unwinding assembly, and a lifting end of the crane is provided with a support plate, and the unwinding assembly is located on the support plate.

[0008] By adopting the above technical solution, the clamping plate is driven by the clamping component to clamp the wall, one end of the lifting rope is connected to the support plate, and then the wall is lifted by the crane. At this time, the straight line connecting the two ends of the wall is parallel to the vertical direction. If you want to make the straight line connecting the two ends of the wall and the lifting rope tilt relative to the vertical direction, you can use the unwinding component to release or reel in the lifting rope at both ends respectively. When the lifting rope is released, the end of the wall connected to the released lifting rope will sink under the action of the wall's own weight. When the lifting rope is reeled in, the lifting rope pulls the clamping plate, and the end of the wall connected to the reeled lifting rope will move up under the tension of the lifting rope, thereby achieving tilting or even tilting the wall to a horizontal state, so that the wall can be smoothly moved to the designated lifting position.

[0009] Preferably, the unwinding assembly includes an unwinding motor, a driving shaft arranged at the end of the unwinding motor drive shaft, a driving gear sleeved on the driving shaft, a driven gear meshingly connected to one side of the driving gear, a driven shaft fixedly inserted in the middle of the driven gear, two bevel gear sets, and two rope winding rods;

[0010] The bevel gear set is arranged in a one-to-one correspondence with the winding rod. The bevel gear set includes a driven bevel gear fixedly connected to the end of the winding rod, and a driving bevel gear meshingly connected to the driven bevel gear. The outside of the driving shaft and the outside of the driven shaft are fixedly sleeved with an integrated driving bevel gear; one end of one of the lifting ropes away from the clamping plate is wound around one of the rope winding rods, and the other end of the other lifting rope away from the clamping plate is wound around the other rope winding rod; and the two lifting ropes have the same winding direction on the rope winding rod.

[0011] By adopting the above technical solution, when the unwinding motor drives the driving shaft to rotate, the driving gear on the driving shaft and the driven gear meshing with the driving gear rotate in opposite directions, and the two driving bevel gears rotate in opposite directions, thereby causing the driven bevel gear meshing with the driving bevel gear to rotate in opposite directions, and then causing the two rope winding rods to rotate in opposite directions. At this time, since the two ropes are wound in the same direction on the rope winding rods, one of the ropes can be released and the other rope can be wound up, thereby causing one end of the wall to move down under the drive of the rope, and the other end to move up under the drive of the rope, so as to speed up the adjustment of the wall position.

[0012] Preferably, a protective sleeve is provided on the periphery of the hanging rope near the clamping plate and the periphery of the hanging rope near the supporting plate, and the hanging rope passes through the protective sleeve along the length direction of the protective sleeve.

[0013] By adopting the above technical solution, the setting of the protective sleeve can, on the one hand, limit the moving direction of the lifting rope, thereby preventing the wall from shaking under the drive of the lifting rope during the lifting process; on the other hand, the setting of the protective sleeve can also protect the lifting rope and prevent it from being hit or worn by foreign objects.

[0014] Preferably, a heat-insulating layer and a flexible pad are provided in the protective sleeve, and the sling is in contact with the flexible pad.

[0015] By adopting the above technical solution, the provision of the insulation layer and the flexible pad both protect the hanging rope, preventing the hanging rope from being worn relative to the inner wall of the protective sleeve, and also preventing the hanging rope from being frozen and cracked.

[0016] Preferably, a slider is provided at the pipe mouth of one end of the protective sleeve close to the clamping plate, and the end of the lifting rope away from the rope winding rod is fixedly connected to the slider. The side wall of the clamping plate is provided with an anti-slip groove for inserting the slider along its length direction, and a limiting bolt is threadedly connected to the clamping plate. The side wall of the clamping plate is provided with a plurality of limiting holes for threading the limiting bolt, and the limiting bolt passes through the slider and is threadedly connected to any limiting hole.

[0017] By adopting the above technical solution, the setting of the slider and the anti-slip groove realizes the adjustment of the connection position of the protective sleeve relative to the clamping plate, thereby realizing the adjustment of the lifting position of the lifting rope to the wall. The lifting position of the lifting rope relative to the wall can be adjusted before lifting. Since the clamping plates are clamped at both ends of the wall, if you want to make the straight line connecting the two side walls of the wall parallel to the vertical state, you can move the slider to one end of the clamping plate. At this time, when lifting the wall, the side of the wall away from the lifting rope will droop under the action of its own weight, thereby realizing the adjustment of the lifting state of the wall.

[0018] Preferably, the clamping assembly is arranged in a one-to-one correspondence with the clamping plate, and the clamping assembly includes connecting plates vertically arranged at both ends of the clamping plate, an insertion rod vertically arranged on each connecting plate, and a driving member for driving the insertion rod to slide back and forth along the length direction of the clamping plate. The length direction of the insertion rod is parallel to the length direction of the clamping plate, and the side walls of the wall near the end are symmetrically provided with insertion holes for inserting the insertion rods.

[0019] By adopting the above technical solution, the driving member drives the insertion rod to slide back and forth along the length direction of the support plate, so that the insertion rod can be inserted into the insertion hole, thereby fixing the clamping plate to the end of the wall, so that the wall can be lifted under the drive of the clamping plate.

[0020] Preferably, the driving member includes a driving motor, a linkage rod rotatably inserted in the clamping plate, screw rods arranged at both ends of the linkage rod, and a linkage plate threadedly sleeved on the outside of each screw rod; the threads of the two screw rods on the same driving member have opposite rotation directions, the driving end of the driving motor is connected to one of the ends of the screw rod, the end of the linkage plate away from the screw rod is connected to the end of the insertion rod, and the linkage plate is located at the end of the insertion rod away from the wall.

[0021] By adopting the above technical solution, the drive motor is started to drive the screw rod, the linkage rod and the two screw rods to rotate. Since the spiral rotation directions of the two screw rods are opposite, the two insertion rods can be driven to move towards or away from each other, so that when the insertion rods approach each other, the insertion rods can be inserted into the insertion holes to achieve convenient clamping of the wall.

[0022] Preferably, a plurality of reinforcing rods are vertically arranged on the side wall of each linkage plate, and the length direction of the reinforcing rods is parallel to the length direction of the insertion rod. The side wall of the connecting plate is provided with a plurality of reinforcing holes for the reinforcing rods to pass through and insert. The reinforcing rods and the insertion rods are internally provided with reinforcing ribs, and the length direction of the reinforcing ribs is parallel to the length direction of the insertion rod.

[0023] By adopting the above technical solution, the provision of reinforcing ribs and reinforcing rods can enhance the support and clamping effect of the clamping plate on the wall, thereby achieving stable lifting of the wall.

[0024] Preferably, the clamping plate includes a first clamping plate arranged at both ends, and several second clamping plates arranged between the two first clamping plates. Linkage rods are inserted inside the first clamping plates. The ends of adjacent second clamping plates are detachably connected, the second clamping plates close to the first clamping plates are detachably connected to the ends of the first clamping plates, the ends of the linkage rods between adjacent second clamping plates are detachably connected, and the linkage rods in the second clamping plates close to the first clamping plates are detachably connected to the ends of the screw rods.

[0025] By adopting the above technical solution, the length of the clamping plate can be adjusted by adding or deleting the second clamping plate without affecting the sliding of the slider and the driving of the insertion rod by the driving member, so that the length of the clamping plate can be adjusted according to the length of the wall end, thereby improving applicability.

[0026] In the first aspect, the present application provides a construction method corresponding to a lifting mechanism for lifting a building wall based on BIM, which adopts the following technical solutions:

[0027] Place the clamping plate against the wall end face, then drive the insertion rod into the insertion hole through the driving member, and then slide the slider as needed to adjust the position of the slider relative to the clamping plate;

[0028] Install the support plate on the crane, lift the wall with the crane, and then start the unwinding motor to release the rope at one end of the wall and reel in the rope at the other end of the wall, thereby adjusting the position of the straight line connecting the two sliders of the wall relative to the vertical direction;

[0029] Use a crane to lift the wall and move it to the designated installation location.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Use the clamping assembly to drive the clamping plate to clamp the wall, connect one end of the lifting rope to the support plate, and then use the crane to lift the wall. At this time, the straight line connecting the two ends of the wall is parallel to the vertical direction. If you want to make the straight line connecting the two ends of the wall and the lifting rope tilt relative to the vertical direction, you can use the unwinding assembly to release or reel in the lifting rope at both ends. When releasing the lifting rope, the end of the wall connected to the released lifting rope will sink under the action of the wall's own weight. When reeling in the lifting rope, the lifting rope pulls the clamping plate, and the end of the wall connected to the reeled lifting rope will move up under the tension of the lifting rope, thereby achieving tilting or even tilting the wall to a horizontal state, so that the wall can be smoothly moved to the designated lifting position;

[0032] 2. The setting of the slider and anti-slip groove realizes the adjustment of the connection position of the protective sleeve relative to the clamping plate, thereby realizing the adjustment of the lifting position of the lifting rope to the wall. The lifting position of the lifting rope relative to the wall can be adjusted before lifting. Since the clamping plates are clamped at both ends of the wall, if you want to make the straight line connecting the two side walls of the wall parallel to the vertical state, you can move the slider to one end of the clamping plate. At this time, when the wall is lifted, the side of the wall away from the lifting rope will droop under the action of its own weight, thereby further realizing the adjustment of the wall lifting state;

[0033] 3. Without affecting the sliding of the slider and the driving of the plug rod by the driving member, the length of the clamping plate can be adjusted by adding or removing the second clamping plate, so that the length of the clamping plate can be adjusted according to the length of the wall end, thereby improving applicability.
