[0016] (III) Beneficial Effects

[0017] This utility model provides a lifting device for building structure construction, which has the following beneficial effects:

[0018] 1. This lifting device for building structure construction, through the arrangement of a mounting plate, motor, first bevel gear, second bevel gear, and lead screw, operates by first starting the motor to drive the first bevel gear to rotate, which in turn drives the lead screw to rotate through the meshing second bevel gear. The threaded engagement of the screw groove causes the mounting plate to slide up and down within the rectangular groove, causing the rotating drum to move up and down accordingly. This up-and-down movement of the drum alters the release length of the wire rope. When the drum moves upward, the release length of the wire rope shortens, thereby increasing the maximum lifting height of the protective plate and its loading platform. Conversely, moving downward reduces the maximum lifting height of the protective plate and its loading platform. This allows the entire lifting device to be applicable to various construction environments with different height requirements, improving its versatility and flexibility.

[0019] 2. This lifting device for building structure construction, through the arrangement of connecting blocks, outriggers, limiting plates, springs, locking rods, threaded rods, and support plates, allows the outriggers to rotate. First, the locking rod is pressed down, causing the limiting plate to move downwards, overcoming the spring force and allowing the locking rod to fully enter the circular groove, disengaging from the circular hole in the connecting block. At this point, the locking rod releases the outrigger's limiting function and can rotate around the axis of the rotating groove. After rotating to a suitable angle, the locking rod is released, and under the spring force, it inserts into the corresponding circular hole in the connecting block, thus fixing the outrigger at a new angle. This adapts to different construction site layouts and equipment placement requirements, improving the adaptability and operability of the lifting device. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a lifting device for building structure construction, including a base 1, with mounting blocks 2 installed on both sides of the top of the base 1. A rectangular groove is formed on the top of the mounting block 2, and a mounting plate 3 is slidably connected to the inner wall of the rectangular groove. A cavity is formed inside the mounting block 2, and a motor 4 is installed on the inner wall of the cavity. A first transmission rod is splined to the output end of the motor 4. A first bevel gear 5 is fixedly connected to one end of the first transmission rod. A second bevel gear 6 meshes with the surface of the first bevel gear 5. A lead screw 7 is fixedly connected to one side of the second bevel gear 6. A threaded groove adapted to the lead screw 7 is formed at the bottom of the mounting plate 3, and the lead screw 7 is threaded into the inside of the threaded groove. A rotating drum 8 is installed on the top of the mounting plate 3, and a winding motor 9 is installed on one side of the base 1. The output end of the winding motor 9 is splinedly connected to a second transmission rod. A steel wire rope 10 is fixedly connected to the surface of the second transmission rod, and the steel wire rope 10 contacts the surface of the rotating drum 8. A loading plate 11 is provided at the center of the base 1, and a protective plate 12 is installed on the top of the loading plate 11. One end of the steel wire rope 10 is fixedly connected to the top of the protective plate 12. Through the arrangement of the mounting plate 3, motor 4, first bevel gear 5, second bevel gear 6, and lead screw 7, when using the device, the motor 4 is first started to drive the first bevel gear 5 to rotate, which in turn drives the lead screw 7 to rotate through the meshing second bevel gear 6. Under the threaded engagement of the threaded groove, the mounting plate 3 slides up and down in the rectangular groove, causing the rotating drum 8 to move up and down accordingly. The up and down movement of the rotating drum 8 changes the permeability of the steel wire rope 10. Release length: When the rotating drum 8 moves upward, the release length of the wire rope 10 shortens, thereby increasing the maximum lifting height of the protective plate 12 and the loading plate 11 on it, and vice versa. This makes the entire lifting device suitable for various construction environments with different height requirements, improving the versatility and flexibility of the lifting device. A connecting block 13 is installed on the front of the base 1. A rotating groove is opened on the front of the connecting block 13. A support leg 14 is rotatably connected to the inner wall of the rotating groove. A circular groove is opened on the top of the support leg 14. A limit plate 15 is movably connected inside the circular groove. A spring 16 is connected between the bottom of the limit plate 15 and the inner bottom wall of the circular groove. A locking rod 17 is fixedly connected to the top of the limit plate 15. The top of the connecting block 13 has multiple round holes that fit the locking rod 17. The locking rod 17 engages with the inside of one of the round holes. The top of the support leg 14 has a threaded hole, and a threaded rod 18 is threaded into the inside of the threaded hole. A support plate 19 is installed at the bottom of the threaded rod 18. Through the arrangement of the connecting block 13, support leg 14, limiting plate 15, spring 16, locking rod 17, threaded rod 18, and support plate 19, when it is necessary to rotate the support leg 14, first press the locking rod 17 down to move the limiting plate 15 downward, so that it overcomes the elastic force of the spring 16, allowing the locking rod 17 to fully enter the inside of the round groove and disengage from the round hole of the connecting block 13. At this time, the locking rod 17 releases the limiting effect of the support leg 14 and can rotate around the axis of the rotating groove. After rotating to a suitable angle,Release the locking rod 17. Under the elastic force of the spring 16, the locking rod 17 is inserted into the corresponding round hole in the connecting block 13, thereby fixing the outrigger 14 at a new angle to adapt to different construction site spatial layouts and equipment placement requirements, improving the adaptability and operability of the lifting device.

[0029] A protective door 21 is rotatably connected to the front of the protective plate 12. The protective door 21 can prevent materials from falling out of the opening of the protective plate 12 during transportation. A fixing component 20 for fixing is installed on one side of the protective door 21.

[0030] A guide wheel 22 is fixedly connected to one side of the mounting block 2. By setting the guide wheel 22, the guide wheel 22 can ensure that the wire rope 10 moves in a specific direction and the surface of the wire rope 10 is in contact with the surface of the guide wheel 22.

[0031] A turntable 23 is fixedly connected to the top of the threaded rod 18. The turntable 23 allows the operator to easily rotate the threaded rod 18. A handle is installed on the top of the turntable 23.

[0032] The bottom of the base 1 is fixedly connected with casters 24. The casters 24 improve the mobility of the device. The casters 24 are arranged in a rectangular shape.

[0033] A rod 25 is fixedly connected to the inner bottom wall of the rectangular groove. A movable plate is provided on the top of the rod 25. The movable plate can ensure that the mounting plate 3 can move in a specific space. A limiting groove adapted to the movable plate is provided inside the mounting plate 3.

[0034] In this invention, the working steps of the device are as follows:

[0035] First step: First, start the motor 4 to drive the first bevel gear 5 to rotate, which in turn drives the lead screw 7 to rotate through the meshing second bevel gear 6. Under the threaded engagement of the threaded groove, the mounting plate 3 slides up and down in the rectangular groove, and the rotating drum 8 also moves up and down accordingly. The up and down movement of the rotating drum 8 will change the release length of the wire rope 10. When the rotating drum 8 moves upward, the release length of the wire rope 10 becomes shorter, thereby increasing the maximum lifting height of the protective plate 12 and the loading plate 11 on it. Conversely, the maximum lifting height of the protective plate 12 and the loading plate 11 on it decreases, making the entire lifting device suitable for various construction environments with different height requirements, thus improving the versatility and flexibility of the lifting device.

[0036] The second step: Next, press down on the locking rod 17 to move the limiting plate 15 downward, so that it overcomes the elastic force of the spring 16 and allows the locking rod 17 to fully enter the interior of the circular groove, so that it disengages from the circular hole of the connecting block 13. At this time, the locking rod 17 releases the limiting effect of the outrigger 14 and can rotate around the axis of the rotating groove. After rotating to a suitable angle, release the locking rod 17. Under the elastic force of the spring 16, the locking rod 17 is driven to insert into the corresponding circular hole of the connecting block 13, thereby fixing the outrigger 14 at a new angle to adapt to different spatial layouts and equipment placement requirements of construction sites, and improve the adaptability and operability of the lifting device.

[0037] Example 1

[0038] Please refer to Figure 5 The fixing component 20 includes a fixing block 2001 and a pin 2002. The fixing block 2001 is installed on the top of one side of the protective door 21. The top of the fixing block 2001 has a through hole, and the pin 2002 is installed inside the through hole. The top of the protective plate 12 has a slot that matches the pin 2002. By setting the fixing block 2001 and the pin 2002, the protective door 21 is effectively prevented from being accidentally opened during the operation of the lifting device.

[0039] Example 2

[0040] Please refer to Figure 6 The fixing component 20 includes a fixing block 2001, an A magnetic block 2003, and a B magnetic block 2004. The fixing block 2001 is installed on the top of one side of the protective door 21, the A magnetic block 2003 is installed on the top of the protective plate 12, and the B magnetic block 2004 is installed on the bottom of the fixing block 2001.
