Description

Technical Field

[0001] The invention relates to the technical field of curtain wall hoisting, in particular to a hoisting mechanism for building curtain walls. Background Art

[0002] Building curtain wall refers to the non-structural external wall system installed on the facade of a building; common curtain wall materials include glass, aluminum alloy, steel, etc.; the construction sequence of building curtain wall installation is to first measure and lay out, then install the L-shaped adapter according to the layout mark of the embedded parts, and then install the columns and beams from bottom to top, that is, connect the aluminum columns with the L-shaped adapter; install the beams on the columns so that the columns and beams form the support frame of the curtain wall; then hoist the prefabricated curtain wall components to each floor through the hoisting mechanism to facilitate the installers to install the prefabricated curtain wall components on the support frame; finally, inject glue into the gaps between adjacent curtain wall components, and after the injection of glue, clean the facade to ensure the beauty of the curtain wall; The existing curtain wall hoisting mechanisms mainly include tower crane hoisting mechanisms, mast hoisting mechanisms and hanging basket hoisting mechanisms; among them, the hanging basket is a suspended hoisting mechanism that can provide a relatively stable and safe working environment, and workers can safely operate and install curtain wall components in the hanging basket; compared with large tower cranes and mast hoisting mechanisms, the hanging basket usually has lower equipment rental and operating costs, and the rise, fall and docking of the hanging basket are controlled by workers in the hanging basket, and the height and position can be adjusted as needed to accurately install curtain wall components; in addition, in the case of narrow space around the building or height restrictions, the hanging basket can also be more easily entered and operated, unlike tower cranes or mast hoisting mechanisms that require a large amount of operating space and layout area; therefore, the hanging basket hoisting mechanism is widely popular in the field of curtain wall construction; Most of the existing hanging baskets are suspended hanging baskets, that is, a hoist is installed on the top of the building, and the hanging basket is connected to the hoist through a wire rope, so that the hanging basket is continuously lifted upward from the bottom of the building under the lifting of the hoist, so as to install the building curtain wall from bottom to top; however, when the wire rope lifts the hanging basket, the change of air flow in the high altitude will exert pressure on the surface of the hanging basket and the curtain wall contained in the hanging basket, thereby causing the hanging basket to swing, which not only affects the stability and accuracy of the staff's operation, but also reduces the efficiency of the curtain wall installation, thereby affecting the overall construction progress; In view of this, in order to overcome the above technical problems, the present invention proposes a hoisting mechanism for a building curtain wall, which solves the above technical problems.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figures 1 to 8 As shown, the hoisting mechanism for a building curtain wall according to the present invention comprises: A suspension frame 1 is provided with a hanging basket 2 below the suspension frame 1; a counterweight 11 is fixedly installed at one end of the suspension frame 1, and a pulley 12 is rotatably installed at the other end; a hoist 21 is fixedly installed at both sides of the hanging basket 2; a steel cable 211 is fixedly installed at the upper end of the hanging basket 2; the end of the steel cable 211 away from the hanging basket 2 passes around the pulley 12 and is connected to the hoist 21, A screw rod 22, which is rotatably connected to a side of the hanging basket 2 close to the suspension frame 1; the threads at both ends of the screw rod 22 are arranged oppositely; both ends of the screw rod 22 are spirally connected to a mounting tube 221; a mounting hole 222 is provided on the surface of the mounting tube 221; a connecting frame 23 is slidably connected inside the mounting tube 221; a connecting hole 237 matching the mounting hole 222 is provided on the surface of the connecting frame 23; a hinged rod 24 is provided on one side of the two connecting frames 23 close to each other; the hinged rod 24 is rotatably connected to the connecting piece through a torsion spring; a drive motor 25 is installed on one side of the hanging basket 2; the drive motor 25 is used to drive the screw rod 22 to rotate.

[0018] As an embodiment of the present invention, a through groove 231 is provided on the surface of the connecting frame 23; two sliders 232 are slidably connected in the through groove 231; the hinge rod 24 is rotatably connected to one side of the slider 232 through a torsion spring; the two sliders 232 are connected by a screw rod 233 through a spiral transmission; the threads at both ends of the screw rod 233 are arranged in opposite directions; a rocker 234 is arranged under the screw rod 233; the rocker 234 is used to drive the screw rod 233 to rotate.

[0019] As an embodiment of the present invention, the rocker 234 is rotatably connected to the connecting frame 23; a bevel gear 235 group is arranged between the rocker 234 and the screw rod 233; the bevel gear 235 group includes two bevel gears 235 meshing with each other; one of the bevel gears 235 is fixedly connected to the lower end of the screw rod 233; the other bevel gear 235 is fixedly connected to one end of the rocker 234 close to the screw rod 233.

[0020] As an embodiment of the present invention, the output shaft of the driving motor 25 is installed with a bevel gear shaft 251; the end of the screw rod 22 close to the driving motor 25 is fixedly connected with a bevel gear ring 223; the bevel gear shaft 251 is meshed with the bevel gear ring 223; a dustproof shell 26 is fixedly installed on one side of the hanging basket 2; the bevel gear ring 223 and the bevel gear shaft 251 are both located in the dustproof shell 26; During operation, the existing hanging basket 2 is mostly a suspended hanging basket 2, that is, a hoist 21 is installed on the top of the building, and the hanging basket 2 is connected to the hoist 21 through a steel wire rope 252, so that the hanging basket 2 is continuously lifted upward from the bottom of the building under the lifting of the hoist 21, so as to install the building curtain wall from bottom to top; however, when the steel wire rope 252 lifts the hanging basket 2, the change of the airflow in the high altitude will exert pressure on the surface of the hanging basket 2 and the curtain wall contained in the hanging basket 2, thereby causing the hanging basket 2 to swing, which not only affects the stability and accuracy of the staff's operation, but also reduces the efficiency of the curtain wall installation, thereby affecting the overall construction progress; In this regard, the present invention sets a hinged rod 24 so that the hinged rod 24 contacts the column used for installing the building curtain wall. When the high-altitude airflow changes and pushes the hanging basket 2 to swing left and right, the hinged rod 24 blocked by the column can block the hanging basket 2 from swinging through the installation tube 221 connected thereto, thereby preventing the hanging basket 2 from swinging, ensuring that the staff can perform the installation stably, not only improving the installation accuracy of the building curtain wall, but also improving the installation efficiency of the building curtain wall, thereby accelerating the overall construction progress of the building curtain wall, so that the practicality of the present invention is improved. In the initial state, the hanging basket 2 is located on the ground, the suspension frame 1 is fixedly installed on the top of the building, and one end of the hanging frame 1 on which the pulley 12 is installed extends out of the side of the building curtain wall to be installed; the hanging basket 2 is suspended below the pulley 12 through the steel cable 211; the counterweight 11 is installed at the end of the hanging frame 1 away from the hanging basket 2, so that the counterweight 11 can balance and stabilize the hanging hanging basket 2; when the staff on the ground carry the curtain wall unit into the hanging basket 2, two staff members then board the hanging basket 2, so that the two staff members stand at both ends of the hanging basket 2 to help balance the weight distribution of the hanging basket 2, ensuring that the hanging basket 2 remains horizontal and stable during the hanging and moving process; the staff controls the hoist 21 so that the motor of the hoist 21 can drive the internal drum of the hoist 21 to rotate, so that the steel cable 211 connected to the hoist 21 is wound around the internal drum, and then the hanging basket 2 is lifted to the required height; when the hanging basket 2 lifts the contained curtain wall unit to the specified height, the staff member takes out the carried curtain wall unit and installs it on the columns and beams; When the curtain wall of a building is being hoisted, the hanging basket 2 is easily affected by the lateral airflow. This is because the airflow in the front-to-back direction is blocked by the building itself and is relatively weak, while the side of the building has no shielding against the airflow. The airflow blowing from the side of the building will directly affect the hanging basket 2, causing the hanging basket 2 to swing left and right. Therefore, the staff needs to first insert the hinged rod 24 between the two adjacent beams above the hanging basket 2. Since the sizes of the curtain wall units used in different buildings are different, the spacing of the installed beams is also different. In the initial state, the two hinged rods 24 installed on the same connecting frame 23 are in a state of being close to each other. When the staff connects the same connecting frame 2 After the two hinged rods 24 of 3 are inserted between two adjacent crossbeams, the staff first drives the driving motor 25 to drive the bevel gear shaft 251 to rotate, so that the bevel gear shaft 251 can drive the bevel gear ring 223 meshing with it to rotate, so that the bevel gear ring 223 drives the screw rod 22 fixedly connected with it to rotate; because the threads at both ends of the screw rod 22 are arranged in opposite directions, the rotating screw rod 22 can drive the two installation cylinders 221 to move in a direction close to each other, so that the two installation cylinders 221 are close to the connecting frame 23; because the installation cylinder 221 is located below the connecting frame 23 at this time, when the installation cylinder 221 is located directly below the connecting frame 23, the staff controls the operation of the hoist 21 to make the hoist The machine 21 can drive the hanging basket 2 to rise, so that the hanging basket 2 drives the mounting tube 221 to rise, and the lower end of the connecting frame 23 is set in a cone shape, so that the connecting frame 23 is easy to quickly insert into the rising mounting tube 221. When the connecting hole 237 on the surface of the connecting frame 23 is aligned with the mounting hole 222 on the surface of the mounting tube 221, the staff uses bolts to insert the mounting hole 222 and the connecting hole 237, and then the mounting tube 221 is fixedly connected to the connecting frame 23; because the mounting hole 222 on the surface of the mounting tube 221 and the connecting hole 237 on the surface of the connecting frame 23 are both provided with a plurality of them, it is convenient for the user to adjust the height of the connecting frame 23 according to the needs, so as to facilitate the use of the user, thereby improving the convenience of the present invention. The user then rotates the rocker 234, so that the rocker 234 can drive the screw rod 233 to rotate through the bevel gear 235 group; because the threads at both ends of the screw rod 233 are arranged in opposite directions, the rotating screw rod 233 can drive the sliders 232 at both ends to move away from each other along the through slot 231, so that the sliders 232 can drive the two hinged rods 24 to move away from each other; and when rotating the rocker 234, the staff needs to control the hoist 21 in real time to release or wind the steel cable 211 to prevent the lower crossbeam from blocking the lower hinged rod 24 from descending, until the upper hinged rod 24 contacts the upper crossbeam, and the lower hinged rod 24 contacts the lower crossbeam;Then, the driving motor 25 is controlled to drive the screw rod 22 to rotate, so that the screw rod 22 drives the two connecting frames 23 to move away from each other through the installation tube 221, so that the hinged rods 24 of the two connecting frames 23 can be driven by the connecting frames 23 to continuously approach the columns on both sides thereof until the hinged rods 24 contact the columns. At this time, the hinged rods 24 are located at the four corners of the rectangle surrounded by the columns and the cross beams. At this time, the connection between the columns and the cross beams blocks and supports the hinged rods 24. Because the connection between the columns and the cross beams is usually the place with the highest structural strength, when the hanging basket 2 is pushed by the lateral airflow, the connection between the columns and the cross beams can effectively support the hinged rods 24 in contact with them. The dust-blocking shell 26 is provided to prevent sand and gravel and other impurities on the surface of the building from falling between the bevel gear ring 223 and the bevel gear shaft 251 under the blowing of the airflow, and prevent the meshing part of the bevel gear shaft 251 and the bevel gear ring 223 from being stuck due to the entry of sand and gravel and other impurities, which not only ensures that the bevel gear shaft 251 and the bevel gear ring 223 can be stably meshed, but also prevents sand and gravel and other impurities from causing wear to the meshing part, thereby increasing the service life of the bevel gear shaft 251 and the bevel gear ring 223, and effectively improving the practicality of the present invention; When the curtain wall unit below the hinged rod 24 is installed, the user controls the hoist 21 to operate so that the hoist 21 can drive the connecting frame 23 to rise, so that the connecting frame 23 drives the hinged rod 24 to rise, so that the hinged rod 24 located above overcomes the torsion force of the torsion spring and rotates downward under the obstruction of the cross beam. At this time, the rotating hinged rod 24 rises under the drive of the connecting frame 23, so that the hinged rod 24 slides and contacts with the upper cross beam until the upper hinged rod 24 passes over the upper cross beam. At this time, the hinged rod 24 is reset and extended under the action of the restoring force of the torsion spring. Similarly, when the hinged rod 24 located below contacts the upper cross beam, the hinged rod 24 blocked by the cross beam overcomes the torsion force of the torsion spring and rotates downward until the lower hinged rod 24 passes over the cross beam. At this time, the hinged rod 24 is reset under the action of the restoring force of the torsion spring, and the rising hanging basket 2 drives the staff to continue the installation of the curtain wall unit.

[0021] As an embodiment of the present invention, a steel wire rope 252 is fixedly connected to the lower end of the connecting frame 23; a circular hole 236 is opened on one side of the mounting tube 221; the end of the steel wire rope 252 away from the connecting frame 23 passes through the circular hole 236 and is connected to the hanging basket 2; and a rubber block 241 is fixedly connected to the lower end surface of the hinged rod 24.

[0022] As an embodiment of the present invention, a mounting rod 261 is arranged between the bevel gear shaft 251 and the output shaft of the driving motor 25; the mounting rod 261 is fixedly connected to the output shaft of the driving motor 25; a groove 262 is provided at one end of the mounting rod 261 away from the driving motor 25; the bevel gear shaft 251 is slidably connected in the groove 262; the bevel gear shaft 251 is connected to the bottom of the groove 262 by a connecting spring 263; an electromagnetic sheet 264 is inlaid at the bottom of the groove 262; the end of the mounting rod 261 close to the bevel gear shaft 251 is rotatably connected to a swivel 265; a rectangular groove 266 is provided in the center of the swivel 265; a rectangular sleeve 267 cooperating with the rectangular groove 266 is fixedly connected to the surface of the bevel gear shaft 251; the end of the wire rope 252 away from the connecting frame 23 is fixedly connected to the surface of the swivel 265.

[0023] As an embodiment of the present invention, a bellows 27 is sleeved on the surface of the screw rod 22; the number of the bellows 27 is three; the two ends of the bellows 27 located in the middle are fixedly connected to two mounting tubes 221; one end of the two bellows 27 located at the two ends of the screw rod 22 is fixedly connected to the mounting tube 221, and the other end is fixedly connected to the hanging basket 2.

[0024] As an embodiment of the present invention, a side of the hinge rod 24 close to the connecting frame 23 is rotatably connected with a ball 242; During operation, when all the curtain wall units in the hanging basket 2 are installed, the user needs to control the hoist 21 to drive the hanging basket 2 to the ground and continue to hoist the new curtain wall units; and in the process of repeatedly hoisting the curtain wall units, the user needs to repeatedly remove the connecting frame 23 and align and adjust the connecting frame 23, which will increase the hoisting time of the curtain wall units and reduce the installation efficiency of the building curtain wall; for this purpose, the present invention provides a steel wire rope 252, and after all the curtain wall units in the hanging basket 2 are installed, the user rotates the rocker 234, so that the rocker 234 can drive the two articulated rods 24 to move away from each other through the screw rod 233, and as the upper articulated rod 24 continues to rise, the upper articulated rod 24 is moved away from each other. The connecting rod 24 rotates under the obstruction of the cross beam. At this time, the hinged rod 24 at the top is pressed against the cross beam at the top under the action of the restoring force of the torsion spring. At this time, the hinged rod 24 at the bottom is pressed against the cross beam at the bottom through the rubber block 241 under the drive of the screw rod 233. The rubber block 241 is elastic, so that the rubber block 241 will be deformed by the blocking force of the cross beam at the bottom, so that the contact area between the rubber block 241 and the cross beam at the bottom is increased, thereby increasing the friction between the cross beam and the hinged rod 24. The rubber block 241 is made of vulcanized rubber material. Vulcanized rubber usually has higher wear resistance and friction coefficient, so that the rubber block 241 made of vulcanized rubber material can increase the friction between it and the cross beam. The friction force causes the connecting frame 23 to be stuck between two adjacent beams by the friction force; at this time, the user pulls out the bolt and controls the electromagnetic sheet 264 to be energized, so that the electromagnetic sheet 264 can generate magnetic force to attract the bevel gear shaft 251 into the groove 262, so that the bevel gear shaft 251 is separated from the bevel gear ring 223, until the bevel gear shaft 251 drives the rectangular sleeve 267 on the surface to contact the rotating ring 265, and controls the driving motor 25 to rotate in the opposite direction, so that the driving motor 25 drives the bevel gear shaft 251 to rotate through the mounting rod 261, so that the bevel gear shaft 251 can drive the rectangular sleeve 267 to rotate until it matches the rectangular groove 266, and at this time, the bevel gear shaft 251 is in the electromagnetic sheet 264. The connecting spring 263 is sucked and squeezed to extend out of the groove 262, and the rectangular sleeve 267 located on the surface of the bevel gear shaft 251 enters the rectangular groove 266 under the drive of the bevel gear shaft 251, so that the bevel gear shaft 251 is slidably connected with the rotating ring 265 through the rectangular sleeve 267, and then the driving motor 25 is controlled to rotate in the opposite direction, so that the driving motor 25 can push the rotating ring 265 to rotate through the rectangular sleeve 267 on the surface of the bevel gear shaft 251, so that the wire rope 252 on the surface of the rotating ring 265 is released, and the hoist 21 is controlled to release the wire rope 211, so that the hoist 21 drives the hanging basket 2 to descend, so that the hanging basket 2 drives the installation cylinder 221 to descend, so that the installation cylinder 221 is separated from the connecting frame 23; After the user lands on the ground and installs the curtain wall unit, the user controls the hoist 21 to wind the steel cable 211 and rise. At this time, the drive motor 25 is controlled to rotate forward, so that the drive motor 25 drives the swivel 265 to rotate forward, so that the steel wire rope 252 is wound around the surface of the swivel 265. Since the end of the steel wire rope 252 away from the swivel 265 is connected to the connecting frame 23, the driving speed of the drive motor 25 is controlled to ensure that the steel wire rope 252 is in a relaxed state to prevent the steel wire rope 252 from winding too fast and pulling down the connecting frame 23. When the installation cylinder 2 When the connecting frame 21 is located directly below the connecting frame 23, the user supports the connecting frame 23 and controls the driving motor 25 to continue winding the wire rope 252, so that the wire rope 252 is in a taut state. Since one end of the wire rope 252 is fixedly connected to the connecting frame 23, and the other end passes through the circular hole 236 of the installation cylinder 221 and is connected to the swivel 265, the taut wire rope 252 can provide a guide for the installation cylinder 221, so that the installation cylinder 221 can be aligned with the connecting frame 23, so as to ensure that the connecting frame 23 can be quickly inserted into the installation cylinder 221, thereby The difficulty of aligning the connecting frame 23 is reduced, the alignment time is shortened, and the hoisting speed of the curtain wall unit is increased, so that the practicality of the present invention is improved; by setting the bellows 27, the bellows 27 can protect the screw 22, prevent the external sand and gravel and other impurities from entering the thread of the screw 22, and thus prevent the sand and gravel and other impurities from blocking the normal driving of the installation cylinder 221, so as to ensure that the installation cylinder 221 can operate stably, and the articulated rod 24 is rotatably connected to the side of the connecting frame 23, so that the articulated rod 24 and the column are connected. The balls 242 make rolling contact between the hinged rod 24 and the column, and when the hanging basket 2 rises, the hinged rod 24 is blocked by the cross beam and rotates downward. The sliding friction between the hinged rod 24 and the column is converted into rolling friction, which reduces the friction between the hinged rod 24 and the column. In addition, the surface of the column is easily solidified in mud or gravel, and the hinged rod 24 will be blocked by mud and gravel when passing through, and rotates upward normally. The rolling contact of the balls 242 can pass through these obstacles more easily and avoid friction, so as to accelerate the upward rotation of the hinged rod 24.
