Description

TECHNICAL FIELD

[0001] The present application relates to a hoisting device, in particular to an automatic fixing large glass hoisting device. BACKGROUND

[0002] When hoisting large glass, the glass is prone to vibration during the lifting process due to its large area and heavy weight, and the influence of high-altitude wind. These vibrations can cause the glass to deviate in the air and easily collide with the outer wall, resulting in edge defects or pits on the glass. In severe cases, the glass may even break in the air. In large glass hoisting operations, the glass is heavy, and it is difficult for workers to install / dismantle the large glass hoisting fixing device. Sometimes, the glass surface can be damaged due to excessive force. SUMMARY

[0003] Therefore, the present application provides a hoisting device with protection function and automatic fixing, which includes a limiting block that can be driven to clamp the glass plate, an air bag layer that can buffer the impact of collision, and a limiting mounting seat. The limiting block is installed at the four corners of the glass plate.

[0004] Further, the limiting block includes a protective pad in direct contact with the glass, two movable limiting movable plates, a limiting block shell, and a rotating block that changes the position of the limiting movable plate. The protective pad is made of a slightly hard gasket to avoid direct friction between the inner wall of the limiting block and the surface of the glass plate, which can cause scratches on the edges of the glass plate during hoisting. The limiting movable plate can be slightly displaced along the length direction of the limiting block shell. By changing the position of the limiting movable plate, an installation slot of different width is formed to accommodate glass plates of different thicknesses installed in the installation slot formed by the two limiting movable plates.

[0005] Further, the protective pad includes a first protective pad in contact with the side surface of the glass plate and a second protective pad in contact with the bottom surface of the glass plate. The side surface of the glass plate refers to the relatively narrow side surface, and the bottom surface of the glass plate refers to the larger area of the glass plate. The first protective pad in contact with the side surface of the glass plate requires higher friction to reduce the vibration of the glass plate during hoisting. The second protective pad in contact with the bottom surface of the glass plate needs to be softer to avoid scratching the surface of the glass plate.

[0006] Further, the rotating block is provided with a rotating cap and a bidirectional screw rod connected thereto. The bidirectional screw rod is axially fixed on the limiting block shell, and the rotation of the rotating cap can drive the rotation of the bidirectional screw rod, but the bidirectional screw rod will not move axially.

[0007] The bidirectional screw rod and the limiting movable plate are connected through threads, the rotating cap can drive the bidirectional screw rod to rotate but the bidirectional screw rod does not move axially, so the limiting movable plate moves axially relative to the bidirectional screw rod, and the two limiting movable plates are installed in two spiral directions of the bidirectional screw rod respectively, so when the screw rod rotates, according to the rotating direction of the screw rod, the two limiting movable plates move away from or close to each other, so the width of the mounting groove formed by the two limiting movable plates changes, thereby realizing clamping and loosening of the limiting movable plate.

[0008] Further, the air bag layer is sleeved outside the limiting block, comprising an air bag shell, an air valve and an air bag, the air bag shell supports and protects the air bag layer from being scratched by external hard objects, and limits the space to prevent the air bag layer from over-inflating; and the air bag shell covers the limiting block, but the air bag shell is provided with an opening to expose the rotating cap of the limiting block, so that the rotating cap can be connected with the fixed mounting seat; the air bag can be inflated through the air valve, and the air bag layer after inflation can buffer and absorb the kinetic energy of the glass plate when accidentally colliding, reducing the damage of the glass plate when being hit, and the air bag layer allows the glass plate to be placed vertically on the ground after being hoisted to the specified position.

[0009] Further, the fixed mounting seat is sleeved outside the air bag layer, which is the core driving structure of the hoisting equipment, and is provided with a gas inlet port matched with the air valve and a rotating groove matched with the rotating cap, the size of the gas inlet port is the same as that of the air valve, and the gas inlet port is easy to plug and unplug, the rotating groove can be driven and is provided with a groove matched with the size of the rotating cap, the cooperation between the rotating groove and the rotating cap should not be too tight or too loose, as long as it is easy to install and remove and does not affect normal rotation; the fixed mounting seat is provided with a driving mechanism for driving the rotating groove to rotate and a small fan for pumping air into the air bag layer, the driving mechanism should have adjustable output torque, at least including a small motor and a corresponding speed reduction mechanism.

[0010] Further, the fixed mounting seat is provided with a battery for supplying power to the driving mechanism and the small fan, and the battery can be replaced; the fixed mounting seat is externally provided with two remote control devices for starting and stopping the driving mechanism and the small fan respectively, the limiting block clamps or loosens the glass plate through the remote control device, and the signal range of the remote control device should not be too large to avoid signal conflict;

[0011] The driving mechanism should set the corresponding normal pressure for clamping the glass plate according to the friction coefficients of the first protective pad and the second protective pad of the actual limiting block, that is, adjust the parameters of the motor and the speed reduction mechanism, so as to change the force of the rotating bidirectional screw rod, and the bidirectional screw rod should be self-locking when it is stationary.

[0012] Further, at least two of the fixed mounting bases are welded with lifting rings for installing lifting ropes for hoisting by a crane, and the fixed mounting bases welded with the lifting rings should be adjacent and cannot be arranged at opposite corners.

[0013] Further, the fixed mounting bases are provided with detachable screw rods, the screw rods and the fixed mounting bases are connected through threads, and both are right threads; the screw rods are arranged between the fixed mounting bases at adjacent corners of the glass plate, and are connected and fixed through screw rod-nut sleeve-screw rod, the threads at both ends of the nut sleeve are in opposite directions, and the middle section of the nut sleeve is a light hole; the nut sleeve with opposite thread directions can be normally installed in the middle of the two right thread directions of the screw rods.

[0021] Therefore, the application provides a hoisting device with protection function and automatic fixing function, which comprises limiting blocks 1 capable of being driven to clamp a glass plate, an air bag layer 2 capable of buffering collision impact, and a limiting mounting base 3.

[0022] In the embodiment, the limiting block 1 comprises a protective pad in direct contact with the glass, two movable limiting movable plates 103, a limiting block shell 102, and a rotating block 101 for changing the position of the limiting movable plates. The protective pad is made of a slightly hard sponge pad to avoid direct friction between the inner wall of the limiting block shell and the surface of the glass plate, which may cause scratches on the corners of the glass plate during hoisting. The limiting movable plates 103 can be slightly displaced along the length direction of the limiting block shell 102, and by changing the position of the limiting movable plates 103, installation grooves of different widths are formed to accommodate glass plates of different thicknesses.

[0023] In the embodiment, the protective pad comprises a first protective pad 104A in contact with the side surface of the glass plate and a second protective pad 104B in contact with the bottom surface of the glass plate. The side surface of the glass plate refers to the relatively narrow side surface, and the bottom surface of the glass plate refers to the larger area surface of the glass plate. The first protective pad in contact with the side surface of the glass plate requires higher friction to reduce vibration of the glass plate during hoisting, and the second protective pad in contact with the bottom surface of the glass plate requires a relatively soft sponge material to avoid scratching the surface of the glass plate.

[0024] In the embodiment, the rotating block 101 is provided with a rotating cap 1012 and a bidirectional screw rod 1011 connected thereto. The rotating cap is a regular quadrilateral, and the bidirectional screw rod 1011 is axially fixed on the limiting block shell. The rotation of the rotating cap 1012 can drive the rotation of the bidirectional screw rod, but the bidirectional screw rod 1011 will not move axially. Small bearings are required at both ends of the bidirectional screw rod 1011, which are specifically set as conventional technology and will not be described here.

[0025] The bidirectional screw rod 1011 and the limiting movable plate 103 are connected by threads. When the rotating cap 1012 is driven, it can drive the bidirectional screw rod 1011 to rotate but not to move axially. Therefore, the limiting movable plate 103 moves axially relative to the bidirectional screw rod, and the two limiting movable plates are installed in the two spiral directions of the bidirectional screw rod 1011. Therefore, when the screw rod rotates, according to the different directions of the screw rod rotation, the two limiting movable plates move away from or close to each other, and the width of the installation groove formed by the two limiting movable plates changes, thereby realizing the clamping and loosening of the limiting movable plates.

[0026] In this embodiment, the air bag layer 2 is sleeved outside the limiting block 1, including an air bag shell 203, a gas valve 201 and an air bag 202. The air bag shell 203 supports and protects the air bag layer from being scratched by external hard objects, and limits the space to prevent the air bag layer from over-inflating. The air bag shell covers the limiting block, but the air bag shell is provided with an opening to expose the rotating cap of the limiting block, so that the rotating cap can be connected with the fixed mounting seat 3. The air bag 202 can be filled with air through the gas valve 201. The air bag layer after inflation can buffer and absorb the kinetic energy of the glass plate when it is accidentally collided, reducing the damage of the glass plate when it is hit. At the same time, after the glass plate is hoisted to the designated position, the air bag layer is provided to allow the glass plate to be placed vertically on the ground.

[0027] In this embodiment, the fixed mounting seat 3 is sleeved outside the air bag layer 2, which is the core driving structure of the hoisting equipment, and is provided with a gas inlet 302 which is connected with the gas valve and a rotating groove 301 which is connected with the rotating cap. The size of the gas inlet is the same as that of the gas valve, and it is easy to plug and unplug. The rotating groove can be driven and is provided with a groove which matches the size of the rotating cap. The cooperation between the rotating groove 301 and the rotating cap 1012 should not be too tight or too loose, as long as it can be easily installed and removed and does not affect normal rotation. The fixed mounting seat is provided with a driving mechanism for driving the rotating groove to rotate and a small fan for pumping air into the air bag layer 2. The driving mechanism should have adjustable output torque, at least including a small motor and a speed reduction mechanism. Here, it is a common transmission scheme in the market, which will not be described here.

[0028] In this embodiment, the fixed mounting seat 3 is provided with a battery for supplying power to the driving mechanism and the small fan, and the battery can be replaced. The fixed mounting seat 3 is provided with two remote control devices which are respectively used to start and stop the driving mechanism and the small fan. The limiting block clamps or releases the glass plate by operating the remote control device. The signal range of the remote control device should not be too large to avoid signal conflict. According to the use scene, a 2.4G signal transmitter is used. The related specific setting scheme and equipment can be easily purchased in the market, which will not be described here.

[0029] The driving mechanism should set the normal pressure for clamping the glass plate according to the friction coefficient of the first protective pad and the second protective pad of the actual limiting block, that is, adjust the parameters of the motor and the speed reduction mechanism. It can be realized by changing the input voltage of the motor. The related setting belongs to the conventional scheme in this technical field, which will not be described here. By changing the output torque of the motor, the force of the rotary bidirectional screw rod 1011 is changed, and the bidirectional screw rod 1011 is self-locked when it is stationary.

[0030] In this embodiment, at least two fixed mounting seats are welded with lifting rings 6 for installing lifting ropes for hoisting machines. The fixed mounting seats 3 welded with lifting rings should be adjacent and cannot be arranged at opposite corners.

[0031] In the embodiment, the fixed mounting base is provided with a detachable screw rod 4, the screw rod and the fixed mounting base are connected through threads, and both are right threads; the screw rod is arranged between the fixed mounting bases of adjacent corners of the glass plate, and is connected and fixed through the screw rod-nut-screw rod mode, the threads in the two ends of the nut are in opposite directions, and the middle section of the nut 5 is a light hole; the nut with opposite thread directions can be normally installed in the middle of the two right thread direction screw rods.

[0032] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
