Description

Technical Field

[0001] The invention relates to the technical field of construction auxiliary equipment, in particular to a building curtain wall installation auxiliary equipment and a construction method thereof. Background Art

[0002] Curtain wall, referred to as curtain wall for short, is a light wall with decorative effect commonly used in modern large-scale buildings and high-rise buildings. Curtain wall is mostly used on the facades of commercial buildings or office buildings. Taking a commercial building or office building with 33 floors as an example, when workers are installing the facades of the 2nd to 33rd floors, they need to use a high-rise building suspended crane for auxiliary installation. However, since each entrance and exit of the ground floor (i.e. the 1st floor) has a tempered glass canopy, workers cannot use a high-rise building suspended crane to install the curtain wall on the facade of the ground floor. For the curtain wall on the facade of the ground floor, multiple workers are usually used to manually erect the curtain wall, and then move the erected curtain wall to the facade, and then install the curtain wall on the facade of the ground floor by setting up scaffolding.

[0003] However, when using the scaffolding in the prior art to install the building curtain wall, there are still certain technical defects, such as: the scaffolding in the prior art is mostly fixed after assembly and installation, and cannot be raised or lowered according to the use height, and the scaffolding in the prior art is difficult to assist workers in loading and unloading the building curtain wall.

[0004] After searching, the Chinese utility model patent with announcement number CN220036049U discloses a lifting scaffold for installing building curtain walls, including two support frames, the front and rear sides of the upper ends of the two support frames are plugged with plug rods, the upper ends of the four plug rods are fixedly connected with vertical poles, the middle parts of the four vertical poles are connected with mounting mechanisms, a load-bearing plate is commonly connected between the four mounting mechanisms, through holes are opened at the four corners of the load-bearing plate, the middle parts of both sides of the lower end of the load-bearing plate are fixedly connected with clamping plates, two retaining rings are sleeved and fixedly connected to the outer sides of some vertical poles above the four mounting mechanisms, and a rotating plate is provided between the two retaining rings on the same vertical pole.

[0005] However, in conjunction with the drawings of the patent document Figure 1-Figure 5 It can be clearly seen that the lifting scaffolding used for installing the building curtain wall is fixed, cannot be raised or lowered according to the use height, and cannot assist workers in loading and unloading the building curtain wall.

[0006] A Chinese utility model patent with announcement number CN220285268U discloses a scaffold for curtain wall installation, including a plurality of inner and outer uprights vertically arranged on one side of a building, wherein the inner and outer uprights are each provided with a plurality of longitudinal horizontal bars, the installation direction of the longitudinal horizontal bars being perpendicular to the length direction of the corresponding inner or outer uprights, a plurality of transverse horizontal bars being provided between the inner and outer uprights, the transverse horizontal bars being provided on the top surfaces of the longitudinal horizontal bars, scaffolding boards being provided on the transverse horizontal bars, fixing components being provided in the scaffolding boards, and movable cavities and sliding cavities being respectively provided in the scaffolding boards, the fixing components comprising an unlocking member rotatably provided in the movable cavity, two driving blocks slidably provided in the sliding cavity, a connecting rod provided on the driving block, two fixing blocks fixedly provided on the inner wall of the sliding cavity, a clamping block provided on the connecting rod, a clamping groove being provided on the transverse horizontal bar, and the clamping block being clamped in the clamping groove.

[0007] However, in conjunction with the drawings of the patent document Figure 1-Figure 4 It can be clearly seen that the scaffolding used for curtain wall installation is also fixed and cannot be raised or lowered according to the height of use. In addition, it cannot assist workers in loading and unloading the building curtain wall.

[0008] Based on this, a building curtain wall installation auxiliary equipment and a construction method thereof are now proposed. Summary of the invention

[0009] 1. Technical issues to be resolved

[0010] In view of the shortcomings of the prior art, the present invention provides a building curtain wall installation auxiliary equipment and a construction method thereof, so as to solve the problems raised in the background technology: when using the scaffolding in the prior art to install the building curtain wall, it still has certain technical defects, such as: the scaffolding in the prior art is mostly fixed after the assembled installation, and cannot be raised or lowered according to the use height, and the scaffolding in the prior art is difficult to assist workers in loading and unloading the building curtain wall.

[0049] To achieve the above object, the present invention also provides the following construction method, comprising the following construction steps:

[0050] S1, equipment movement and positioning:

[0051] S1-1, make sure the hydraulic telescopic cylinder is in the retracted state, with the outriggers on the ground and the universal wheels suspended in the air, check whether all parts of the equipment are firmly connected, and whether the screw rods, transmission belts, etc. are normal;

[0052] S1-2, when the equipment is moved, the hydraulic telescopic cylinder is started to extend. As the hydraulic telescopic cylinder extends, the piston rod pushes the lower shaft rod, causing the swing arm to rotate downward around the pin on the U-shaped connecting seat;

[0053] S1-3, when the swing arm rotates until the universal wheels touch the ground and support the equipment, the extension operation of the hydraulic telescopic cylinder is stopped. At this time, the weight of the equipment is borne by the four universal wheels, and the four legs are not in contact with the ground;

[0054] S1-4, by pushing the equipment, use the universal wheels to move the equipment to a suitable position at the construction site for the installation of the building curtain wall;

[0055] S1-5, after the equipment is in place and reaches the predetermined position, the hydraulic telescopic cylinder is started to retract it, the piston rod pulls the lower shaft rod, and the swing arm rotates upward around the pin axis until the legs touch the ground again and stably support the equipment. At this time, the universal wheels are suspended in the air and in a folded state. When the four legs touch the ground again and stably support the equipment, the equipment is in a stable state;

[0056] S2, building curtain wall loading:

[0057] S2-1, start the servo reduction motor, and the output shaft of the servo reduction motor drives the active pulley to rotate;

[0058] S2-2, the driving pulley drives the two driven pulleys to rotate through the transmission belt, thereby causing the two screws to rotate synchronously;

[0059] S2-3, since the screw nut is fixed on the holder, the holder is connected to the guide slider and the lifting platform, the rotation of the screw will cause the screw nut to move up and down along the screw, thereby driving the lifting platform to adjust to a suitable height. This height should be convenient for workers to load the building curtain wall into the U-shaped mounting frame. During the operation, the limit side wing of the guide slider slides in the slide groove of the inverted U-shaped fixing frame, and the sliding sleeve slides on the guide rod to ensure the smooth lifting of the lifting platform;

[0060] S2-4, curtain wall loading: Move the building curtain wall to the vicinity of the equipment and align it with the U-shaped mounting bracket on the lifting platform;

[0061] S2-5, clamp and install the building curtain wall into the corresponding U-shaped mounting frame. During the installation process, multiple suction cups on the side wall of the U-shaped mounting frame will absorb and fix the building curtain wall to ensure the stability of the curtain wall during the loading process;

[0062] S3, building curtain wall lifting and installation:

[0063] S3-1, start the winch, and the reel of the winch starts to reel in the wire rope;

[0064] S3-2, the free end of the steel wire rope passes through the circular groove of the lifting platform and the mounting hole of the connecting cross plate, and is fixed to the rope buckle. As the winch is wound, the steel wire rope lifts the two U-shaped mounting frames upward, and the building curtain walls installed on the two U-shaped mounting frames are also lifted upward synchronously;

[0065] S3-3, curtain wall installation: According to the height requirement of the installation position of the building curtain wall, the height of the lifting platform is adjusted again by the servo reduction motor so that the building curtain wall reaches the installation position;

[0066] S3-4, workers install the building curtain wall on a lifting platform or other safe working platform, and accurately install the building curtain wall on the building facade;

[0067] S4, device reset:

[0068] S4-1, after the installation of the building curtain wall is completed, the suction cup is released from the building curtain wall, the steel wire rope is released, and the lifting platform returns to the initial position;

[0069] S4-2, turn off the servo reduction motor and winch;

[0070] S4-3: If you need to move the device to the next installation location, repeat the operation steps of S1.

[0071] Beneficial effects:

[0072] The present invention provides a building curtain wall installation auxiliary device and a construction method thereof, which have the following beneficial effects:

[0073] 1. In the present invention, the auxiliary equipment realizes the lifting function of the lifting platform through the cooperation of the servo reduction motor, the belt transmission system, the tensioner, the driven pulley and the transmission belt, the lead screw and the lead screw nut. During the installation of the building curtain wall, the position of the building curtain wall can be accurately adjusted according to different installation height requirements, and is no longer restricted by the fixed height of the traditional scaffolding, thereby overcoming the technical defects of the traditional technology that the scaffolding is fixed and the use height cannot be adjusted.

[0074] 2. In the present invention, the liftable design of the auxiliary equipment enables the equipment to quickly adapt to different installation scenarios, reduces manual adjustments or equipment replacements due to inappropriate heights, and greatly improves the work efficiency of building curtain wall installation. Workers can adjust the curtain wall to the required height in a short time, thereby speeding up the entire installation process.

[0075] 3. In the present invention, the multiple suction cups on the U-shaped mounting frame in the auxiliary equipment can absorb and fix the building curtain wall. During the loading and unloading process, these suction cups can effectively prevent the curtain wall from being damaged due to shaking, tilting, etc. For example, when the curtain wall is transported to the equipment or removed from the equipment and installed on the facade of the building, the adsorption effect of the suction cups can ensure the stability of the curtain wall position, which provides convenience for loading and unloading.

[0076] Fourth, in the present invention, the auxiliary equipment including the winch, steel wire rope, rope buckle, U-shaped mounting frame and connecting cross plate can assist in the installation of the building curtain wall. This function makes up for the defect that the scaffolding in the prior art is difficult to assist in the loading and unloading of the building curtain wall, and reduces the labor intensity of the workers.

[0077] 5. In the present invention, the slide groove on the inverted U-shaped fixing frame in the auxiliary equipment cooperates with the limiting side wings of the guide slider, and the combination of the sliding sleeves and guide rods at the four corners of the lifting platform provides a stable guide for the lifting platform. During the lifting process, it can be ensured that the lifting platform does not deviate, ensuring the smooth lifting of the building curtain wall. This stable structural design can prevent the curtain wall from shaking, colliding, etc. during the lifting process, thereby improving the reliability of the equipment and extending the service life of the equipment.

[0078] 6. In the present invention, the setting of the tensioner in the belt drive system of the auxiliary equipment can adjust the tension of the drive belt, ensuring the effective transmission of power. Through the reasonable layout of the pulleys and the V-shaped design of the drive belt, the power transmission is made more stable and efficient, reducing the situation where the equipment cannot work normally due to transmission failure, and further improving the reliability of the equipment.

[0079] 7. In the present invention, since the U-shaped mounting frame is plugged and installed in the rectangular through groove of the lifting platform, it can be appropriately adjusted according to the size of the building curtain wall to a certain extent. For building curtain walls of different widths and heights, as long as their sizes are within the range allowed by the equipment, they can be installed through the equipment, which improves the versatility and applicability of the equipment and reduces the demand for installation equipment for curtain walls of different sizes.

[0080] 8. In the present invention, each leg of the auxiliary device is connected to a universal wheel through a swing arm. This design enables the device to change direction easily when it needs to be moved;

[0081] The universal wheels can rotate 360°, allowing the equipment to be flexibly moved to a suitable position on the construction site, reducing manpower consumption and operating difficulty during equipment movement;

[0082] The setting of the hydraulic telescopic cylinder allows the equipment to flexibly switch between the mobile state and the fixed working state. When the hydraulic telescopic cylinder is extended, the swing arm drives the universal wheel to touch the ground, and the equipment can be moved through the universal wheel; when the hydraulic telescopic cylinder is retracted, the universal wheel is suspended in the air and is in a folded state, the outriggers touch the ground, and the equipment is in a stable supporting state, which is suitable for the installation of building curtain walls;

[0083] The swing arm is movably installed on the U-shaped connecting seat through a pin shaft. This movable installation method allows the swing arm to rotate flexibly around the pin shaft. Combined with the telescopic operation of the hydraulic telescopic cylinder, the angle of the swing arm can be accurately controlled, thereby controlling the lifting and lowering of the universal wheel, making the switching of the equipment between the mobile and fixed states more stable and controllable.

[0147] The upper limit ring 31 on the upper shaft rod 29 and the lower limit ring 32 on the lower shaft rod 30 can effectively prevent the shaft rod from axial movement during operation. During the telescopic operation of the hydraulic telescopic cylinder 28, the limit ring ensures the relative position stability of the upper shaft rod 29 and the lower shaft rod 30, thereby ensuring the stability of the movement of the swing arm 26, preventing the equipment from shaking or deflecting when moving or working, and improving the overall stability and safety of the equipment;

[0148] The swing arm 26 is movably mounted on the U-shaped connecting seat 25 via a pin shaft. This movable mounting method enables the swing arm 26 to flexibly rotate around the pin shaft. Combined with the telescopic operation of the hydraulic telescopic cylinder 28, the angle of the swing arm 26 can be accurately controlled, thereby controlling the lifting and lowering of the universal wheel 27, making the switching of the equipment between the mobile and fixed states more stable and controllable.

[0149] Embodiment 5

[0150] like Figure 1-11 As shown, the present invention also provides a construction method for building curtain wall installation auxiliary equipment, comprising the following construction steps:

[0151] S1, equipment movement and positioning:

[0152] S1-1, ensure that the hydraulic telescopic cylinder 28 is in a retracted state, at which time the outrigger 101 is on the ground and the universal wheel 27 is suspended in the air, and check whether the various components of the equipment are firmly connected, and whether the screw rod 11, the transmission belt 18, etc. are normal;

[0153] S1-2, when the equipment is moved, the hydraulic telescopic cylinder 28 is started to extend, and as the hydraulic telescopic cylinder 28 extends, the piston rod pushes the lower shaft rod 30, causing the swing arm 26 to rotate downward around the pin shaft on the U-shaped connecting seat 25;

[0154] S1-3, when the swing arm 26 rotates until the universal wheels 27 touch the ground and support the equipment, the extension operation of the hydraulic telescopic cylinder 28 is stopped. At this time, the weight of the equipment is borne by the four universal wheels 27, and the four legs 101 are not in contact with the ground;

As the winch 21 is wound up, the steel wire rope 22 lifts the two U-shaped mounting frames 19 upward, and the building curtain walls installed on the two U-shaped mounting frames 19 are also lifted upward synchronously;

[0166] S3-3, curtain wall installation: According to the height requirement of the installation position of the building curtain wall, the height of the lifting platform 3 is adjusted again by the servo reduction motor 13 so that the building curtain wall reaches the installation position;

[0167] S3-4, workers perform installation operations on the building curtain wall on the lifting platform 3 or other safe working platforms, and accurately install the building curtain wall on the facade of the building;

[0168] S4, device reset:

[0169] S4-1, after the installation of the building curtain wall is completed, the suction cup 24 is released from the building curtain wall, the wire rope 22 is released, and the lifting platform 3 returns to the initial position;

[0170] S4-2, turn off the servo reduction motor 13 and the winch 21;
